Improvements in Rolling Mills.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Bucking-
ham Street, Strand, W.C., London, Patent Agent, do hereby declare the nature
of this invention, a communication to me from abroad by Henry Grey, Mechanical
Engineer, of Duluth, Minnesota, United States of America, to be as follows:-
My invention relates to improvements in mills or apparatus for rolling metallic
beams, girders, columns, etc.
One object of my present invention is to prevent the formation of crop ends
or projecting elongations of the web upon the finished product, in rolling work
of the character indicated.
A further object is to prevent cracking or tearing of the flanges or heads of
the work, or other mutilation of the work, during the rolling operation.
Another object is to more satisfactorily and effectually guide the work, and
prevent displacement of the work during the passage of the latter through the
mill, and to obtain a perfectly straight product.
A further object is to reduce the cost of a product of the character indicated,
and to successfully and accurately roll large and heavy blanks that cannot be
successfully rolled by any mill or process heretofore devised.
With these objects in view, and to the end of realizing other advantages herein-
after appearing, and, particularly, to the end in view of rolling large and heavy
work accurately and economically, my invention consists in certain features of
construction, and combinations of parts, hereinafter described and pointed out.
In the accompanying drawings, Fig. I is a top plan of my improved mill or
apparatus, and portions are broken away in this figure to reduce the latter's
size and to more clearly show the construction.

tively of the work's path, and engaged upon their outer sides, by simultaneously
operated pressure exerting devices shown in the said figure.
My improved apparatus or mill for rolling columns beams, or girders, com-
prises two systems of rolls, one roll system A for rolling the edges of the heads
or flanges of the column, beam or girder, (that is hereinafter termed the blank,
or the work, or the product), and another roll system. B for rolling opposite
sides of the flanges or heads and the web of the work. The two roll systems A
and B are located in line and in such proximity to each other that the blank
or work can be fed from the one system to the other, and the work, in
feeding it from the one to the other roll system shall be received
by the latter before it has left the former and the rolling or operating surfaces
of the rolls of both systems of rolls are driven positively and in the direction
required to feed in opposite directions alternately, and the work is given as many
passes through the mill as are required to complete the rolling or shaping of
the work, and the blank or work is, of course, suitably heated preparatory to
its introduction into the said rolling mill, and the work is fed through the mill
with its web arranged horizontally.
The roll system B comprises a top horizontal roll B¹, a bottom horizontal roll B2
and two vertical side rolls D) and D) arranged at opposite ends, respectively of
said horizontal rolls and all of said rolls are positively rotated in the direction
required to feed the work, as will hereinafter appear. Roll B₁ is arranged hori-
zontally and transversely of the work's path in the position to operate upon the
upper side of the web of the work and upon the inner sides of the work's flanges
.or heads above the web. Roll B2 is arranged below and traversely
of the works path in position to operate upon the lower side of
the work's web and upon the inner sides of the work's heads or
flanges below the web. The two upright rolls D and 11 are arranged
at opposite sides respectively of the work's path in position to operate upon
the outer side of the adjacent flange or head of the work. The work C is shown
in position in Figs. IV and IX. Rolls B B are, of course, rotated in opposite
directions, respectively and rolls D D¹ also rotate in opposite directions respec-
tively.
Roll system A comprises preferably two rolls A¹ and A* arranged at the top
and bottom, respectively, of the work's path, in position to operate upon the edges
of the flanges or heads of the work. That is, the top roll A¹ operates upon the
upwardly presented edges, and the bottom roll A3, when it is engaged by the
work, operates upon the downwardly presented edges.
Two feed tables C₁ and C2 are arranged at opposite ends, respectively, of the
work's path through the mill. Feed table C¹ is located adjacent to roll system B.
and is provided with any suitable number of suitably driven feed rollers C³.
Feed table C is located adjacent to roll system A and comprises any suitable
number of suitably driven feed rollers C. The work is fed from one of the
feed tables to the other feed table, and is passed in opposite directions alter-
nately.
Any mechanism or apparatus suitable for positively driving rolls B¹ B2 of
roll system B and rolls A¹ and A* of roll system A. is provided, and, in the case
illustrated, a trunnion A12 of the lower roll A* of the roll system A. (see Fig. VI)
is operatively connected by means of a suitable coupling or connection A4, with

page_text: a suitably supported horizontally arranged shaft a and a trunnion A³ of the
upper roll A is operatively connected, by means of a suitable coupling or con-
nection A, with a horizontal shaft a arranged above and parallel with shaft a.
Two spur gears a² a³, operatively mounted upon shaft a and a¹, respectively,
and having a corresponding number of teeth, mesh with each other, and gear a
meshes with a driving pinion at operatively connected, in any approved manne,
with a suitably supported and suitably actuated driving shaft a. Hence, rolls A
and A are driven in opposite directions, respectively, as required.
Another pinion a (see Fig. V) is operatively mounted upon driving shaft as
and meshes with a spur gear a operatively mounted upon a horizontal shaft 8
suitably supported at one side of and a suitable distance from shaft and opera-
tively connected, by means of suitable couplings or connections with a spur
gear arranged in line with shaft a8 and between said shaft 18
and the trunnions (see Fig. V) of the lower roll Be of roll
system B and any suitable couplings or connections establish opera-
tive connection between said trunnions bl and gear
A spur
gear a is arranged above and parallel and meshes with spur gear 10. Gear a¹l
is operatively connected, by suitable couplings or connections with one of
the trunnions 64 of the upper roll B of roll system B. The arrangement and
relative size of the gear wheels employed in establishing operative connection
between the engine shaft and rolls A A B and B are preferably such that
the rolling or operating surfaces of said rolls shall be driven at the same speed,
or nearly so.
The two rolls B1, B2 are driven in opposite directions respectively as already
indicated and the upper roll B and the lower roll B2 are driven in the same
direction as the upper
roll A¹ and lower roll A* respectively of
roll system A, and hence the work can be fed from rolls A'
to rolls B' B³ or vica
versa, according as the driving shaft is
actuated in the one direction or the other, and the two systems
of rolls are preferably arranged in sufficiently close proximity to each other to
enable the one system of rolls as already indicated to operate upon the work
before the latter has left the other roll system.
The bottom roll 132 of roll system B is suitably supported from the two hous-
ings G G arranged a suitable distance apart at opposite sides, respectively of
the work's path and suitably tied together and braced apart by rods G³. It is
obvious that for work of the character indicated one or both of the horizontal
web reducing rolls must be adjustable vertically and the upright side rolls D
and must be adjustable apart and in the case illustrated the top roll B₁
is adjustable toward and from the bottom roll 132 and it is also obvious that the
said upright rolls D D and the top roll B are preferably adjusted simul-
taneously relative to the works path, and I have discovered that the said upright
side rolls in adjusting them apart simultaneously with the adjustment of the
top roll must be moved more rapidly than the top roll in order to avoid long crop
ends and torn or cracked flange edges on the finished product.
It is well known by those skilled in the art that the extensions of the web in
the finished product, beyond the ends of that portion of the product that is prac-
tically perfect and called crop ends in the trade are cut off and worth no more
than scrap material and it will therefore be observed that any device or means
instrumental in reducing the length of the crop ends from several feet to a few
inches is of no inconsiderable importance. Crop ends should be avoided, if
possible, and this is practically accomplished in the mill that forms the subject
matter of this application as will hereinafter more fully appear.
I have found that the best results are obtained by moving rolls D and D¹
about one and one fourth times as fast as the movement of the top roll B; during
the adjustment of said rolls. It is obvious that the rolls at the commencement
of the operation of the mill are set as required to accommodate the passage

page_text: between them of the heated blank and generally in the first pass of the work little
more is accomplished than the straightening of the blank.
be
I would here remark that if the rolls D D', in their movement toward and
from each other, were travelling at the same rate as the travel of the top roll
toward and from the bottom roll, all of said rolls will have travelled the same
distance and if for instance the rolls were set say for a finished product to have
one half inch thickness of web and a half inch thickness of flange,
the top horizontal roll B¹ would at the completion of the work
brought within that distance of the bottom horizontal roll, and
the side rolls D D would be brought within that distance of the ends
of the horizontal rolls that form as already indicated the inner sides of the
flanges or heads and web of the work. Now, if the top roll, in its movement
toward the bottom roll, moves at the same rate each of the side rolls move,
in the latter's movements toward each other, and if the top roll's travel during
the rolling of the work is two and one half inches, it follows that after the top
roll has travelled two and one half inches, all the rolls (B¹ D D¹) will have
travelled the same distance, and the top roll B₁ will be three inches from the
bottom roll 12 and the side rolls D D will be the same distance namely three
inches from the flange rolling surfaces of the horizontal rolls B B2. Now, it is
evident that if an even reduction of all parts of the work is to be effected, and
the travel of the top and side rolls, during the adjustment of the said rolls,
were the same, not only had no allowance been left for overcoming the distortion
caused by the shear in cropping or cutting the blank, which is always much
greater on the flanges than on the web, but long crop ends will be had on
the finished product. This subject of long crop ends will be readily under-
stood upon consideration of the fact that the flange rolling surfaces of the hori-
zontal rolls B1 B2 always revolve more slowly than the peripheral or web rolling
surfaces of said rolls, because the flange rolling surfaces of said rolls extend
nearer to the axes of the rolls than the latter's web rolling surfaces and if the
side rolls DD) are not caused to work more vigorously than the horizontal
rolls the finished product will probably be found cracked or torn at the edges
of the heads or flanges and a. great deal of material that should be equally or
properly distributed between the web and flanges and thereby increase the length
of the perfect product, will have been robbed by the web rolling surfaces of the
horizontal rolls to form extensive elongations of the web at the ends of the
product, which elongations or crop ends have to be cut off and are not worth
any more than scrap material, and if the edges of the flanges or heads are muti-
lated the whole product is practically worthless and forms very expensive scrap.
Instead therefore of desiring only to reduce the flanges at the same rate as the
web, I have found it invaluable to reduce the flanges considerably faster than
the web in order to make up for the much slower rate of delivery at the points
of the horizontal rolls from which the edges of the flanges are delivered from
the speed of those parts of the horizontal rolls at which the web is delivered and
when the side rolls D D₁ are adjusted toward each other more rapidly to the
extent required than the movement of the top roll B₁ relative to the bottom
roll B², it will be found that cracking or tearing of the edges of the flanges of
the product will always be avoided. Hence, by travelling the side rolls about
twenty five per cent. more rapidly, in the setting of the said rolls, than the top
roll, in the aforesaid two and one half inch travel of the top roll during the
reduction of the work, there will be room for the admittance of say at least
three eights of an inch more material into each of the flanges and a further
allowance of one fourth inch to a side to accommodate any distortion of the
blank or work, and the latter can be finished without torn or cracked edges and
without long crop ends on the finished part. The additional material going
into the flanges, it will be observed, is instrumental in adding to the length of
the finished product (flanges as well as web) and is not robbed by the web for the
objectionable purpose already indicated.

page_text: Before referring to the mechanism employed for effecting the adjustment of
said adjustable rolls B. D and D¹ I would remark that live surfaces should be
present to all sides of the work, and consequently all of said rolls and the bottom
roll B2 should be rotated positively and in unison. A suitable operative con-
nection between each of said upright rolls D and D and the adjacent trunnion
of the upper horizontal roll B' comprises, preferably, a horizontal friction disc d
(see Figs. III and IV) operatively connected with the respective upright roll
in any approved manner and preferably by the formation of interlocking lugs d³
and 13 upon said friction disc and the roll, respectively. The upright roll'is
bored centrally, as at D (see Fig. IV) and the lugs D³ are formed upon the
upper portion of the surrounding wall of said bore. The friction disc is, therefore.
arranged within or extends into the upper portion of the bore through the roll,
and the aforesaid interlocking lugs are arranged vertically to accommodate an
up and down movement or adjustment of the friction disc for the purpose herein-
after made more apparent. Said friction disc d, at its upper end is provided
with an external annular friction surface 2 that is frictionally engaged by a
corresponding annular friction disc B3 formed upon, or operatively connected
with, the adjacent trunnion of the upper horizontal roll B

horizontal roll 13, that, it will be observed, is supported from the said discs.
The means acting to elevate each friction disc d and maintain frictional
engagement between said friction disc and the engaging friction disc 133, com-
prises, preferably, a piston E (see Fig. IV) that is secured to the said disc d in
any approved manner. The piston extends downwardly in to the chamber f
formed in the vertical cylindrical lug or cylinder F formed upon the inner end
of a horizontally arranged slide H, and upon said cylinder the upright roll, that

or passage way f¹ for conducting water or fluid under pressure to chamber fis
formed, in any approved manner, within a lower head of said cylinder, and
communicates with the aforesaid chamber. The fluid under pressure, within
said chamber, acts to force the piston upwardly and thereby causes the hori-
zontal friction disc d to be held in frictional contact with the engaging friction
disc B³ and supports the top roll Bt. A stuffing box is provided around
the piston at and supported by the upper end of cylinder F, and prevents upward
leakage of the fluid under pressure from chamber f. Each housing G, near its
lower end, and at the top of the trunnions of the lower horizontal roll, (see
Figs. III and IV) is provided with laterally and outwardly projecting brackets G¹
that are provided with suitably constructed slideways G2 designed for slides H
and arranged parallel, therefore, with the direction in which the side rolls D
and D are adjustable. That is two horizontally movable slides H H are
arranged at the outer sides of the different housings, respectively. One of said
slides carries roll D and the other slide carries roll D. Both slides H H are
adjustable toward and from each other, and the two rolls D D¹ are moved there-
or from each other according as slides H H are actuated
fore toward
toward or from each other. Each slide His provided preferably with two
screws H arranged parallel with the slideways for said slide and a suit-
able distance apart, and operatively connected with the slide in any approved
manner. Screws H engage, preferably, correspondingly threaded nuts I con-
fined or held stationary within recesses g¹ formed in the outer sides of the afore-
said slideway forming housing brackets, and by this construction, it is obvious

page_text: that each slide H and the roll supported thereby are adjusted toward or from
the pair of horizontal rolls B 12, according as the engaging screws are turned
in the one direction or the other.
Each slide H is provided, also with a thrust bearing J for the upright roll,
which bearing is constructed in any approved manner.
The upright screws L L (see Figs. I, II, and IV) engage correspondingly
threaded holes formed in the tops of housings G G, and are arranged to form
stops that limit the upward movement or elevation of the upper horizontal roll 13¹.
Saddles are interposed between the lower ends of said screws and the trunnions
of said roll, and one of the said saddles is shown and marked 1, in Fig. II. By
this construction, it is obvious that upon turning screws L in the direction
required to elevate them, the upper roll B will be elevated by the action of
the fluid under adequate pressure upon pistons E, and upon turning the said
screws in the opposite direction the said roll will be lowered against the said
pressure.
My present invention involves, broadly, the required greater reduction of the
space between the side rolls than between the top and bottom rolls, during
the setting of the said rolls, and specifically embraces not only the travel of the
side rolls D D¹ more rapidly than the movement of the top roll B' in the simul-
taneous adjustment of said rolls, but embraces, also, any device, mechanism or
apparatus whereby the screws L instrumental in adjusting the top roll vertically
and the screws H² employed in adjusting apart the side rolls are operatively
connected together in such a manner that they are shifted endwise simul-
taneously, and at the same time the side roll adjusting screws are shifted more
rapidly so that rolls D D¹ shall be moved more rapidly than roll B¹ in setting
said rolls, and to this end, in the case illustrated, the threads of screws H2 have
twenty five per cent. more pitch than the threads of the screws L, as shown in
Fig. VII.
The mechanism employed for rotating screws L and H2 is, preferably, as
follows; upon the upper end or portion of each screw L (see Figs. Ï, II
and IV) is operatively mounted a worm wheel L¹ that meshes with a worm M
formed upon a suitably supported horizontally arranged shaft M. The upper
ends of screws L are, in the case illustrated, angular in cross section and extend
through corresponding holes in the central portion of the engaging wheels L'
so that the said screws are capable of endwise movement independently of the
said wheels L' without interrupting operative connection between the said
wheels and screws. Upon the outer end of each screw H2 of a slide H (see
Figs. I, III and IV) is operatively mounted a bevel gear he that meshes with
a bevel gear h³ operatively mounted upon horizontally arranged shaft + sup-
ported from brackets H that are rigid with the said slide. Shaft M is inter-
geared as at m (see Fig. 1) with the reversibly rotatable shaft m¹ of an electric
motor m². Each shaft his operatively provided, also, with a worm wheel h
that meshes, with a worm formed upon an upright shaft 7 that, at its lower
end, is supported from a bracket rigid with the adjacent slide H and at
its upper end, is supported from a standard H2 rigid with the said slide.
bevel gear 8 is operatively mounted upon the upper end of the said shaft
and meshes with a bevel gear m8 mounted operatively and slidably, by means
of groove and feather m upon the shaft M; and said gear is carried by the
aforesaid standard H12. By the construction just described, it is obvious that
the mechanism establishing operative connection between the shaft M and the
screws of each slide H is carried by and movable with the said slide. By the
construction just herein before described it will be observed that all of the said
screws L and H2 are operatively connected with one and the same motor shaft m',
and are consequently movable in unison. All the gears and worm wheels of the
mechanism that establishes operative connection between shaft M and the said
screws correspond diametrically, and the worms of the said mechanism corre-
spond in diameter, so that all the screws are rotated at the same speed when
A

page_text: they operate. Hence, in the case illustrated, the more rapid endwise, movability
of screws H² is due solely to the greater pitch of the threads of the said screws.
Of course, the members of the mechanism establishing operative connection
between the reversible shaft m¹ and screws H2 and L are preferably so arranged
that the side rolls 1) ]) and top roll 13 shall be simultaneously shifted inwardly,
or outwardly, according as the said shaft is rotated in the one or the other
direction and the said rolls are set as required at the commencement of the
operation of the mill upon a predetermined size of blank, to form the initial
passage way, between the said side rolls and between the top and bottom rolls,
for the said blank, and the said adjustable rolls are adjusted as required to
reduce the said space after each subsequent pass of the said blank. I would here
remark that so far as concerns the shifting of slides H simultaneously with
more rapidly than the shifting of the top roll B¹, my invention involves,
broadly, any mechanism for accomplishing the said results.
Roll's A¹ and A of roll system A (see Figs. I and II) are of course, arranged
in the same vertical plane, and roll A¹ has its trunnions resting in half boxes A
movable up and down within the two upright housings A5 that are arranged at
opposite sides, respectively, of the works path. Half boxes A* rest upon and
are consequently supported from any suitable number of upright bars or rods A
(see Fig. VI) operatively connected at their lower ends, with vertically tilting
weighted levers A' whose weights A8 somewhat more than counterbalance the
weight of roll A¹ and act in the direction required to elevate said roll. Saddles
or blocks A⁹ rest upon the trunnions of roll A¹ above half boxes A and suit-
ably operated screws A10 engage correspondingly threaded holes in the tops of
the housings and engage the upper surfaces of saddles A9 and not only limit
the upward movement of roll A but are instrumental in lowering the said roll
against the action of weights A8 Roll A¹ is adjustable vertically, therefore,
as required preparatory to operating upon the edges of the heads or flanges of
a predetermined piece of work. Screws A10 when they are rotated or turned,
are operated uniformly, and the mechanism employed for uniformily operating
said screws comprises, preferably, two beveled gears A. A" operatively mounted
on the different screws, respectively, above the housings, and meshing with
heveled gears Ab that are operatively mounted upon a horizontally arranged
shaft A suitably supported above the housings, and the arrangement of said
last mentioned gears relative to gears A is such that the screws, when the said
shaft is rotated, are simultaneously turned in the same direction.
A gauge for regulating the width of the heads or flanges of the work is pro-
vided and comprises, preferably, a collar i (see Figs. I and II) mounted upon
the bottom roll A* of roll system A, at the under side of the path of, and
arranged to afford bearing for, the web of the work, between the paths of the
work's flanges or heads. The central portion of roll A is provided, preferably
with an annular groove or recess Ad and collar i is mounted upon roll A* within
the said recess. Said collar, therefore, affords bearing, as already indicated, for
the work during the operation of rolls A¹ and A. The side walls of recess Ad
prevent endwise displacement of the collar upon the roll A, and the portions of the
roll A at opposite sides, respectively, of said recess are instrumental, when
they are engaged by the work, in operating upon the edges of the heads or
flanges of the work. One of the rolling portions of roll A* is keyed, as at A°,
(see Fig. II) or otherwise removably secured, to the remaining portion of the roll,
to accommodate the mounting of collar 41 upon the central reduced portion of
the roll and, of course, said keyed part of the roll is not applied until after the
collar has been placed in position. Collar i is adjustable vertically as required to
enable it to be lifted or elevated a suitable distance after each pass of the work
and thereby render roll A¹ capable of operating as required upon the upwardly
presented edges of the work's flanges or heads. The vertical adjustability of
collar i is obtained preferably by having the collar's hole through which the
as shown in
central portion of roll A* extends constructed
Fig. II.

page_text: Roll A is supported from housings A5, in any approved manner, and collar i
is supported preferably, by a saddle arranged below the collar and having
its upwardly facing surface arranged circumferentially of and concentrically
with the collar, and anti-friction rollers are interposed between said surfaces.
of the saddle and the lower external surfaces of the collar that turns upon said
rollers during the operation of the mill. Saddle has two sides i arranged
at opposite ends, respectively, of the collar, and the antifriction rollers ex-
tend between and are supported from said sides. The means employed for
adjusting or moving collar i vertically comprises preferably an upright screw
that extends through and engages a correspondingly threaded nut 26 that is
located a suitable distance below saddle 2 and rendered stationary in any ap-
proved manner. A suitably supported worm wheel is operatively connected
in such a manner, for instance, by feather and groove 28 with screw that the
latter can move endwise independently of the said wheel without interrupting
operative connection between said wheel and said screw 25. Worm wheel
meshes with a worm that is formed upon a suitably supported horizontally
arranged shaft 2¹0 (see Figs. I and II) and shaft 10 is intergeared at at 21 with
a suitably supported shaft ¹ that extends diagonally to shaft M and is inter-
geared, as at 13 with the said shaft M.
It will be observed therefore that screw 25 is operatively connected with the
motor shaft m¹ so that the setting or adjusting of collar i preparatory to each
pass of the work for the purpose, as already indicated, of gauging or controlling
the width of the work's flanges is effected simultaneously with the adjustment
of the adjustable rolls of roll system B worm wheel worm and gears 13
correspond diametrically with the worm wheels, worms and gears that officiate
in establishing operative connection between shaft M and screws L H2, so that
screw is rotated at the same speed as screws H2 and L. Therefore, if collar i
is to be shifted about one half as far as the top roll B₁ of roll system B, as
desired, it follows that the threads of screw 5 (see Fig. VII) have fifty per
cent. less pitch than the threads of the screws L employed in adjusting the said
roll. The said collar or cylinder i will, therefore, in shifting rollers B₁ and DDI,
raise one half as much as the said roll B₁ lowers and this is desired inasmuch
as the position of the said member i determines the width of the work's flanges.
As the rolls B B² dig into the web of the blank or work, the distance between
the upper side of the works web and upper roll A¹ is increased in proportion
and this being the case, although there is no collar or cylinder i on said roll A¹,
still as the work that is being operated upon, can be turned at will, as will
hereinafter more fully appear, it follows that the distance between member i
and roll A, for the initial pass of the work. is determined by the position of
the roll A relative to the position of the said member i, and this distance is
increased or decreased, for the work's initial pass, by raising or lowering the
said roll A¹, according as wider or narrower flanges or heads upon the finished
product are desired. The lowering of the top roll B₁ of roll system B will result
in raising member i one half of the distance travelled by the said roll B¹ and
member will consequently gauge or control the width of the work's flanges
or heads after the mill has commenced to operate. The function performed by
member is therefore primarily, the gauging of the width of the work's heads
or flanges, and as the work is turned over at suitable intervals as will presently
appear, it follows that the edges of the flanges of the finished product will be
even.
I would here remark, however, that my invention embraces broadly, a gauge
forming collar or cylinder on either one of the flange edge rolling rolls and
arranged to engage the work's web between the flange edge rolling portions of
the said roll, and my invention, so far as rolling of the works flanges is con-
cerned, embraces, also and broadly a reduction of the space between the said
collar or cylinder and the roll relative to which the said cylinder or collar is
adjustable, less to the extent required than the reduction of the space between

page_text: the top and bottom web reducing rolls B₁ B2, in the setting of the said adjustable
members after a pass of the work and before the work's next pass.
In other words, I would have it understood that although I consider the details
of construction, illustrated and described in this application, desirable and
valuable, my invention is not limited to the said details, but embraces any means
suitable for accomplishing the desired results herein enumerated.
The diagonal shaft is made, preferably, in two sections arranged end to
end and provided, at their adjacent ends, with a clutch that has one of its parts ¿¹5
fixed to the shaft's upper section and has the companion part operatively and
slidably mounted upon the shaft's lower section. The slidable clutch member
is shifted in any approved manner to cause it to operatively engage or disengage
the companion clutch member. Suffice it to state here that operative connec-
tion between screw and the shaft M is established or interrupted according as
the said clutch is rendered operative or inoperative, and the operation of the said
screws is, therefore, under the control of the operator.
The rollers and 1, (see Figs. I and II) arranged transversely of the lower
side of the work's path, at opposite sides, respectively, of roll A, are instrumental
in guiding the work to and fro and from said roll system A, and the roll that is
located between the said roll system A and table C2 is a feed roller that is suitably
driven in the direction required to feed the work to and from the said roll
system from and to the said table. The said table comprises any suitable number
of feed rollers C, as already indicated, and the feed roller at the inner end of
the table is operatively connected, by means of sprocket wheels and chain C³,
with feed roller ¹. Operative connection between the feed rollers of the table
is established, preferably, by shafting and gears C suitably driven to feed the
work in the direction required (see Fig. 1). To remove scales from the work,
that can be readily removed by a tumbling process, the work, when it is upon
table C, is automatically overturned any suitable number of times, and this
process of tumbling the work is valuable also as already indicated, to insure
adequate operation on all of the edges of the work's flanges in roll system A.
The means employed for overturning the work upon table C2 comprises
preferably, (see Figs. VIII and IX) an oscillating shaft C7 that is suitably sup-
ported below and arranged horizontally and longitudinally to the table and is
provided at two points, located a suitable distance apart, with two arms C8 C³
extending transversely of the table, and arranged to engage the work upon the
table from below and throw the work laterally against the inclined uprights or
backs C with which the table is provided. Each arm C8 of shaft C7 is arranged
to operate between two adjacent feed rollers of the table, so that said rollers
shall not interfere with the location and operation of said arms. Arms C8, in
their normal or inoperative position, are below the path of the work that, in
solid lines, Fig. IX. is shown resting upon the feed rollers of the table, and. in
dotted lines in same figure, in shown thrown laterally against the inclined sur-
faces of backs C, which inclined surfaces extend upwardly and outwardly from
their lower extremities. Each arm C has its outer portion bent or extending
upwardly, so that said outer portion, when the work is thrown against backs C⁹,
shall overlap the work and prevent the latter from rebounding back into the same
position upon the table, and the inclined surfaces of members C are sufficiently
far from a perpendicular that the work, when the work tumbling arms
returned below the table, will fall with its opposite side upon the table.
said over turning operation is repeated, if desired, any suitable number of times,
and is very effectual in shaking scales from the work. The means for oscillating
the work over turning shaft comprises, preferably, (see Fig. IX) a gear Cio
that is operatively mounted upon the shaft, preferably at some point between
the two arms C8, C8, and said gear meshes with a reciprocating rack C that is
arranged transversely of the feed table, between two adjacent feed rollers of
said table, and attached, in any approved manner, to the rod C12 of the pis-
ton C³ of a hydraulic engine or motor C¹. In order to render the action of the

are
The

page_text: extremities of arms Cs easy, in overturning the work upon table C, each of
said arms, at its outer end, is provided with a wheel or roller C that engages
the work in the overturning operation and prevents the arm from holding
onto or detaining the work during the said operation, and, in order to render
the over turning of the work still more positive, and positively insure the over-
turning of the work during the overturning operation of the said arms C³.
one or more hydraulic cylinders C16 are provided. In the case illustrated, two
cylinders C are arranged at a suitable distance apart and at right angles to
table at the rear of backs C. Each cylinder C₁ is provided internally with
a piston C capable of reciprocating endwise of the cylinder's chamber and
actuated by fluid, under pressure, admitted to the cylinder in any approved
manner, and the said piston has its rods C18 extending forwardly, and the said
rod, when actuated forwardly, engages the lower portion of the work from the
rear, and participates in the over turning of the work and renders the over-
turning operation infallible. (19 designates a forward side guide for the work
in the latter's passage over table C² and is, of course, arranged along the for-
ward side of the work's path. The forward or outer end of each rod or push-
ing device C18 is provided, preferably, with an upright arm C20 that is pivoted
horizontally and transversely at C21 to the said rod, and, at the rear of its axis,
is provided with a weight or poise, C23 that acts to retain arm C in the latter's
upright or normal position. The said weight C22 normally straddles the rod C18
and engages the upper side of the rod, and the said arm cannot therefore, tilt
rearwardly beyond its normal position. The arrangement of parts is such that
the said arm, when in its normal position, projects above the table far enough
to engage upon being actuated forwardly, the lower portion of the work thrown
against back C³ and participate in overturning the work upon the said table
and the work when overturned tilts the said arm forwardly and downwardly
out of the way if the said arm is struck by the over turning work, and hence
the said arm is not injured in case it is struck by the overturned work.
Two suitably formed bottom guides or bearings Q Q¹, (see Figs. I and II)
for the work are provided at opposite sides, respectively, of rolls 131 132 of roll
system B at the under side of the path of the work. Guide Q₁ is arranged
between roller j and roll B2 and extends into close proximity to the said roll B².
Guide Q is arranged between roll B2 and table C₁ and extends into close
proximity to the said roll. Said guides prevent downward displacement of
the work in the latter's passage to and from roll system B.
A top guide T for the work in the passage of the work from the roll system B
to the roll system A is provided (see Figs. I and II), for the purpose of pre-
venting the work from being thrown upwardly out of its path in said passage.
Said guide consists, preferably, of an approximately horizontally arranged
heavy plate suspended over and in close proximity to the path of the upper side
of the work's web and between the paths of the work's flanges. Guide T is
located between the two roll systems and in close proximity to roll B¹ of roll
system B. Guide T is movable vertically to accommodate its adjustment corre-
spondingly and simultaneously with the vertical adjustment of the top web
reducing roll B¹. To effect the movement of guide T simultaneously with and
in the same direction as the vertical movement of roll B¹, and to prevent any
injury to any parts by any upward blow received by said guide from the work
in the passage of the work below the guide, the following construction is pro-
vided the guide, at or near its central portion, is suspended by means of a rod
or bar T that depends from one end of a vertically tilting weighted lever Tª and
is attached, at its lower end to the guide in any approved manner. Lever T2
is supported from a vertically movable slide 13 that extends between and
engages vertical slideways (not shown) formed upon housings G G. The
said lever is fulcrumed, therefore to any suitable member that is rigid with or
supported from the said slide, that, near each end is suspended from a pis-
ton T (see also Fig. XI) arranged to operate within and endwise of an upright

page_text: stationary cylinder T5 having closed ends. Two upright cylinders T5 T5 are
provided, therefore, over opposite ends, respectively, of slide T3 (and the latter
is suitably attached to the piston rods To depending from the pistons within
said cylinders. Each cylinder T5 (see Fig. XI) is provided with two lateral
ports 1 and T8 at the upper end and the lower end, respectively, of the cylinder.
The lower port T8 connects the lower extremity of the cylinder's chamber with
a pipe or pressure line T employed in supplying water or other fluid under
adequate pressure into said chamber below the piston in said chamber. The
fluid pressure upon pistons T from below acts to lift guide T, and I would here
remark that the poise T, with which lever T2 is preferably provided, counter-
balances preferably the aggregate weight of the guide T and the connection
between the fever and the said guide. Adjacent to each cylinder T5 is provided
another stationary upright cylinder T that is preferably integral with the said
cylinder T5 and is closed at its lower end open at its upper end. A piston T12
is arranged to operate within and endwise of each cylinder T, and the latter,
at its lower end, is provided with a lateral port 13 that is required in the
establishment of open relation between the lower extremity of the chamber of
the said cylinder and the port T7 of the adjacent cylinder T. The cylinders T
above the pistons therein, the cylinders T below the pistons therein, and the
connections between ports T and T13, are supplied with water or other suitable
fluid from any suitable number of supply pipes T¼. Each piston T¹² has its
rod T15 extending downwardly below the cylinder and operatively connected
with an arm projecting laterally from and rigid with the saddle upon the
adjacent trunnion of the top web reducing roll B. The said piston T, and
consequently the guide T, will, therefore, move downwardly correspondingly with
any downward travel of the top web reducing roll B'. It is obvious that, as already
indicated, the top web reducing roll B and with it the flange reducing
rolls D D¹, are set, preparatory to the first pass of a heated blank that requires
reducing, the distance apart required for the first pass, which distance forms
the largest work receiving passage between said rolls during the reducing opera-
tion upon the blank, and said passage is rendered smaller preparatory to each
successive pass of the work. It follows, therefore, that the work's top guide T
must be correspondingly set preparatory to every pass of the work. The opera-
tive connection of pistons T12 with the saddles 7 on the top roll B lowers the
said pistons T, as already indicated, upon lowering the said roll B, and water
is thereby displaced from below said pistons in cylinders T into the upper ends
of cylinders 15, through the connections between said cylinders, and the water
forced into said cylinders T depressed the pistons T against the power exerted
by the water from the pressure line, and thereby lowers the guide the distance
required. Guide T bears against or abuts the under side of slide T³ as at T16
(see Fig. II), so that the guide cannot tilt. After the work has had its finishing
pass, the rolls are again adjusted to enlarge the work receiving passage between
them as required for another blank, and the elevation of the top roll B during
said resetting of the rolls by the pressure upon them by the horizontal friction
discs d as soon as the screws L are backed up, lifts pistons T12, permits the dis-
placement of water from the upper ends of cylinders T into cylinders T and
accommodates the elevation of pistons T by the power from the pressure line,
and thereby results in the corresponding elevation of the work's top guide T.
It will, therefore, be observed that said guide is adjusted simultaneously and
uniformly with the adjustment of the top roll B It is desirable to lock the
said roll and the said guide in the desired adjustment, so that they cannot be
displaced vertically during the pass of the work, and I interpose, therefore, a
valve V (see Figs. I and XII) in the line of the pipe connection between
cylinders T and T which valve controls continuity in the passage way between
each cylinder T and the adjacent cylinder T. When, therefore, said valve is
closed water cannot pass between the said cylinders and the said top roll and
the said guides are locked against vertical displacement, and when the said

page_text: valve is open water can pass between the said cylinders and accommodate the
vertical adjustment of the said guide and roll. It is obvious, therefore, that
valve V should be opened simultaneously, or practically simultaneously, with
the commencement of the endwise shifting of screws L and should be closed
simultaneously, or practically simultaneously, with the cessation of the endwise
movement of the said screws. Before proceeding to describe the mechanism
preferably employed for operating valve V, I would remark that said valve is
arranged, preferably, in a valve casing V₁ having a port V2 connected, by means
of a tee V3 with the two pipes V* V*. One of said pipes! V connects with the port T
of one of cylinders T" and the other pipe V is connected with the port T13 of
the other cylinders T". The seat V for the valve is formed at the inner end of
said port V2 and the latter, at its inner end, connects with a passage way V6
extending through the valve casing, and having its opposite ends connected with
different pipes V7 V7 respectively. One of pipes V7 connects with the port T
of one of cylinders T and the other pipe. V7 connects with the port T
of the other cylinder T. By this construction, it is obvious that, when the
valve is shifted off its seat, open relation is established between cylinders T
and T, and said communication is interrupted when the valve is seated.
The valve V for establishing and interrupting communication between the
chambers of adjacent cylinders T5 and T, has a stem V8 extending outside of
the valve casing and operatively connected at its outer end (see also Fig. X),
with a tilting lever V at any suitable point between the opposite ends of the
lever that is fulcrumed, at one end, as at V10, to any suitable support, and, at
its opposite end, is operatively connected, by means of a rod or suitable con-
nection V with the endwise movable core or cores of a solenoid V12. A suit-
ably applied spring V13 acts to retain the core or cores of the solenoid in their
outer or normal position and also acts to retain the valve V in its closed position,
wherein the chambers of adjacent cylinders T and T are not in open relation
with each other and water cannot flow between said chambers as already indi-
cated. However, when an electric current traverses the solenoid, the core or
cores of the solenoid are moved against the action of the said spring and move
lever V in the direction required to open the valve whereupon communication
between said chambers is established as required to accommodate the flow of water
from cylinders T5 to cylinders T, or vice versa, according as roll B is elevated
or lowered. An electric current is caused to traverse the solenoid, therefore,
in any approved manner, simultaneously, or practically simultaneously, with
the commencement of the operation of screws L L, so that the said cylinders
shall be placed in open relation with each other simultaneously, or practically
simultaneously, with the commencement of the operation of said screws, and the
said solenoid is rendered inactive, in any approved manner, simultaneously, or
practically simultaneously, with the cessation of the operation of screws L L so
that communication between the said cylinders shall be interrupted simul-
taneously, or practically simultaneously, with the cessation of said screws opera-
tion. A desirable manner of simultaneously, or practically simultaneously
effecting operation of the solenoid and electric motor, and thereby move valve V
simultaneously with the commencement of the said screws' operation, involves
the arrangement of the solenoid and motor in series in one and the same electric
circuit, as shown in Fig. X, and the electric current is controlled and reversed
at pleasure by any approved controller having a current reverser incorporated
therein. Devices for controlling an electric current and reversing the latter's
direction, and the placing of electric receptive devices in series are so well under-
stood by those skilled in the art that the largely diagrammatic illustration in
Fig. X will be readily understood, and further description or illustration thereof
in this application is considered unnecessary.
The connection of the electric
motor and solenoid in series is important, therefore, because a disabling of
either one of said electro receptive devices would at once interrupt the flow of
electric current, and simultaneously, or practically simultaneously, interrupt the

page_text: operation of the other electro receptive device, and consequently there is no
liability of the operation of the screws when valve V is closed, nor is there any
liability of the closing of the valve while the screws are operating.
Two side guides r r for the work (see Figs. I, II. and III) extend from roll
system B to and beyond roll system A, and are arranged at opposite sides, respec-
tively. of the work. Said guides r r extend into close proximity to the rolls
of roll system B and are cut away at the top below roll A', as at r¹, to accommodate
the location and operation of the said roll A. Guides rr extend a suitable distance
beyond the outer side of roll system A into suitable proximity to table C³.
Guides are parallel, supported in any approved manner, adjustable or mov-
able laterally, and operatively connected, by suitably applied bars, rods or
devices 2. at points between roll system B and roll system A. with slides H
and H, respectively, and hence, said guides are moved apart or toward each other
according as rolls D and D¹ are shifted toward or from each other, and simul-
taneously with and to the same extent as the movement of the said rolls D D¹.
The said guides r. r. between roll system A and table C2 are engaged, upon their
outer sides, by extensions or members ³ ³ of pistons (see Fig. I) arranged
and operated as required to move the said ends of guides rr toward
each other simultaneously with the shifting of rolls B D D' and guide T.
Guides are set as required for the work's initial pass to accommodate the pas-
sage of the heated blank between them, and after the first pass the said guides
are shifted toward each other preparatory to each pass, to reduce the width of
the passage way between them and continue to properly perform their function
of guiding and preventing lateral displacement of the work during the opera-
tion of the mill upon the work. One member 3 engages and is arranged at
the outer side of and at right angles to one of the guides r. and the other mem-
ber engages and is arranged at the outer side of and at right angles to the
other guide r. Each piston 4 is arranged to operate. within a stationary hori-
zontally arranged closed chamber cylinder 5 that at its outer end, has its
chamber connected with a piper employed for supplying water or other fluid
under pressure to the piston in said cylinder. and thereby actuate the said pis-
ton in the direction required to move the engaging guider laterally and in-
wardly. Both pipes are connected with a main supply pipe by a valve
casing, and a valve 7 (see Fig. I) in said valve casing interrupts and establishes
communication between the main pipe 7 and the branch pipes . The con-
struction of said valve and valve casing is substantially the same
as the
construction of valve V and valve casing V1, and the stem 710 of valve r³ is
operatively connected with a vertically tilting lever that is fulcrumed at
one end, as at 1 to any suitable support, and has its opposite end connected
with the core or cores of a solenoid 13 that is electrically energized in any ap-
proved manner and may be connected in series with the solenoid V12 and the
motor m² Valve 9 may, however, be operated in a different manner, if desired,
and suffice it to state, therefore, that any suitably operated valve for controlling
the supply of pressure to cylinders is employed and is opened to admit pres-
sure or additional pressure to the said cylinders simultaneously, or practically
simultaneously, with the inward shafting of rolls B¹ D D¹ and guide T.
The arrangement of parts is such that when an electric current traverses
solenoid 13, valve is opened against the action of means, such for instance as
a spring acting in the direction required to retain the valve seated. Fluid
can be removed from within cylinders through valved drain pipes 15 with which
said cylinders are provided (see Fig. I).
Two side guides R R for the work (see Figs. I, II, III, and XIII) are provided
between table C and roll system B at opposite sides, respectively, of the work's
path, and extend into close proximity to rolls B₁ B². Each guide R is sup-
ported from the adjacent slide H in any approved manner and said guides are.
therefore moved toward or from each other according as the side rolls D and D'
of roll system B are shifted foward or from each other. In the case illustrated,

page_text: each guide R is supported, at or near its inner end, at R¹, (see Fig. III) in any
approved manner, from the supporting slide H, but, at its outer end, is sup-
ported from the slide through the instrumentality of an endwise movable bar
or rod R2 (see Figs. III and XIII) that is supported from and is movable with
as well as independently of the slide. Said bar extends through a suitable
constructed stationary chambered cylinder R³ that is closed at its ends and rigid
with a lug G formed upon the adjacent housing G. The said bar extends
easily through said lug and loosely through a lug H³ formed upon the slide.
The outer end of the bar is round and screw threaded, and two nuts R6 R7 are
mounted upon the bar at opposite sides, respectively of the said lug H3 and
farther apart than the opposite ends of the said lug. The bar, within cylinder R³,
is provided with a piston R arranged to move endwise of the cylinder's chamber
and actuated inwardly, as required to press the attached guide R laterally and
inwardly, by water or fluid under pressure conducted into the outer end of the
cylinder, by a pipe R5 that communicates with the outer end of the cylinder's
chamber. Nut R6 constitutes a stop that limits the outward movement of the
bar independently of the slide, and consequently the bar in its normal position
has the said nut R engaging the lug H3 of the slide and is shifted inwardly
with the slide in moving the side rolls toward each other. The space between
lug H3 and the outer nut R7 of the bar is the distance that the bar can move
independently of the slide, and hence, the bar, when under endwise pressure by
the fluid introduced into cylinder R, will press the attached guide laterally and
inwardly, and the two guides R R are pressed inwardly or toward each other
during the last pass of the work to restrict the passage way between the said
guides at bars R2 R2 to approximately the width of the finished product (measur
ing widthwise of the web) so as to insure that the finished product will,
practically, be perfectly straight.
It follows therefore, that bars R2 R2 are located at the mill's end at which
the finished product is delivered, and the finishing pass is, preferably from roll
system A to roll system B. as in the case illustrated.
The two pipes R³ leading to the two cylinders R³ are connected with a main
supply pipe R8 that is provided with any suitably constructed three way valve R
capable of establishing and interrupting communication between cylinders R³
and pressure line R8 and capable also of draining the said cylinders. The con-
struction of valves of the character indicated is so well known that detailed
description or illustration thereof is not considered necessary in this application.

Improvements in Rolling Mills.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Bucking-
ham Street, Strand, London, W.C., Patent Agent, do hereby declare the nature
of this invention a communication to me from abroad by Henry Grey, Mechanical
Engineer, of Duluth, Minnesota, United States of America, and in what manner
the same is to be performed to be particularly described and ascertained in and
by the following statement:—.
My invention relates to improvements in mills or apparatus for rolling metallic
beams, girders, columns etc.
One object of my present invention is to prevent the formation of crop ends

page_text: or projecting elongations of the web upon the finished product, in rolling work
of the character indicated.
A further object is to prevent cracking or tearing of the flanges or heads of
the work, or other mutilation of the work, during the rolling operation.
Another object is to more satisfactorily and effectually guide the work, and
prevent displacement of the work during the passage of the latter through the
mill and to obtain a perfectly straight product.
A further object is to produce the cost of a product of the character indicated
and to successfully and accurately roll large and heavy blanks that cannot be
successfully rolled by any mill or process heretofore devised.
With these objects in view, and to the end of realizing other advantages herein-
after appearing, and, particularly to the end in view of rolling large and heavy
work accurately and economically, my invention consists in certain features of:
construction, and combinations of parts, hereinafter described and pointed out.
in the claims.
In the drawings left with my Provisional Specification. Fig. 1 is a top plan
of my improved mill or apparatus, and portions are broken away in this figure
to reduce the latter's size and to more clearly show the construction. Fig. II
is a side elevation of the same, largely in central vertical section. Fig. III is

rolls. Fig. VII is a view showing, detached, one of the screws employed in the
adjustment of the top web reducing roll, one of the screws employed in the ad-
justment of the upright flange reducing rolls, and the screw employed in the
adjustment of the devices employed in gauging or controlling the width of the
work's flanges. Fig. VIII is a side elevation, mostly in vertical section, of the
mill's feed table that is provided with work overturning apparatus. Fig. IX is

employed in connection with a top guide for the work. Fig. XII is a vertical
section of the casing containing the aforesaid valve V. Fig. XIII is an eleva-
tion of two side guides arranged at opposite sides, respectively, of the works
path, and engaged, upon their outer sides by simultaneously operated pressure
exerting devices shown in the said figure.
My improved apparatus or mill for rolling columns beams or girders, com-
prises two systems of rolls, one roll system A for rolling the edges of the heads
or flanges of the column, beam or girder, (that is hereinafter termed the "blank,"
or the work," or the "product"), and another roll system B for rolling opposite
sides of the flanges or heads and the web of the work. The two roll systems A
and B are located in line and in such proximity to each other that the blank
or work can be fed from the one system to the other, and the work, in
feeding it from the one to the other roll system shall be received
by the latter before it has left the former, and the rolling or operating surfaces
of the rolls of both systems of rolls are driven positively and in the direction
required to feed in opposite directions alternately, and the work is given as many
passes through the mill as are required to complete the rolling or shaping of
the work, and the blank or work is, of course, suitably heated preparatory to

page_text: its introduction into the said rolling mill, and the work is fed through the mill
with its web arranged horizontally.
The roll system B comprises a top horizontal roll B', a bottom horizontal roll B²
and two vertical side rolls D and D arranged at opposite ends, respectively, of
said, horizontal rolls and all of said rolls are positively rotated in the direction
required to feed the work, as will hereinafter appear. Roll B is arranged hori-
zontally and transversely of the work's path in position to operate upon the
upper side of the web of the work and upon the inner sides of the work's flanges
or heads above the web. Roll 12 is arranged below and transversely
of the work's path in position to operate upon the lower side of
the work's web
and upon
the inner sides of the work's heads or
Hanges below the web. The two upright rolls D and D¹ are arranged
at opposite sides respectively of the work's path in position to operate upon
the outer side of the adjacent flange or head of the work. The work C is shown
in position in Figs. IV and IX. Rolls B1 B2 are, of course, rotated in opposite
directions, respectively, and rolls D D¹ also rotate in opposite directions respec-
tively.
Roll system A comprises preferably two rolls A¹ and A* arranged at the top
and bottom, respectively, of the work's path, in position to operate upon the edges
of the flanges or heads of the work. That is, the top roll A¹ operates upon the
upwardly presented edges, and the bottom roll A, when it is engaged by the
work, operates upon the downwardly presented edges.
Two feed tables C and C2 are arranged at opposite ends, respectively, of the
work's path through the mill. Feed table C is located adjacent to roll system B
and is provided with any suitable number of suitably driven feed rollers C³.
Feed table C is located adjacent to roll system A and comprises any suitable
number of suitably driven feed rollers C. The work is fed from
one of the feed tables to the other feed table, and is passed in opposite direc-
tions alternately.
Any mechanism or apparatus suitable for positively driving rolls B1 B2 of
roll system B and rolls A¹ and A* of roll system A is provided, and, in the case
illustrated, a trunnion A of the lower roll A* of roll system A (see Fig. VI)
is operatively connected by means of a suitable coupling or connection A with
a suitably supported horizontally arranged shaft a and a trunnion A³ of the
upper roll A is operatively connected, by means of a suitable coupling or con-
nection A15 with a horizontal shaft arranged above and parallel with shaft a
Two spur gears a² a³, operatively mounted upon shaft a and a', respectively,"
and having a corresponding number of teeth, mesh with each other, and gear a
meshes with a driving pinion operatively connected, in any approved manner,
with a suitably supported and suitably actuated driving shaft as. Hence rolls A¹
and A are driven in opposite directions, respectively as required.
Another pinion (see Fig. V) is operatively mounted upon driving shaft 5
and meshes with a spur gear a operatively mounted upon a horizontal shaft 48
suitably supported at one side of, and a suitable distance from shaft a5 and opera-
tively connected by means of suitable couplings or connections a with a spur
gear arranged in line with shaft 8 and between said shaft a8 and
the trunnion 61 (see Fig. V) of the lower roll 12 of roll system B,
and any suitable couplings or connections 62 establish operative con-
nection between said trunnion bl and gear
A spur gear
is arranged above and parallel and meshes with spur gear a¹. Gear a
is operatively connected by suitable couplings or connections with one of
the trunnions 6 of the upper roll 11 of roll system B. The arrangement and
relative size of the gear wheels employed in establishing operative connection
between the engine shaft and rolls A¹, A*, B1 and B2 are preferably such that
the rolling or operating surfaces of said rolls shall be driven at the same speed,
or nearly so.
The two rolls B1, B2 are driven in opposite directions, respectively, as already

page_text: indicated and the upper roll B¹ and the lower roll B2 are driven in the same.
direction as the upper roll A¹ and lower roll A, respectively of
roll systemi A, and hence, the work can be fed from rolls A¹, A³,
to rolls B1, B2, or vice versa, according as the driving shaft 1s
actuated in the one direction or the other, and the two systems
of rolls are preferably arranged in sufficiently close proximity to each other to
enable the one system of rolls, as already indicated, to operate upon the work
before the latter has left the other roll system.
The bottom roll 132 of roll system B is suitably supported from the two hous-
ings G G arranged a suitable distance apart at opposite sides respectively, of
the works path, and suitably tied together and braced apart by rods G³. It is
obvious that, for work of the character indicated, one or both of the horizontal
web reducing rolls must be adjustable vertically, and the upright side rolls D
and D must be adjustable apart, and in the case illustrated, the top roll B₁
is adjustable toward and from the bottom roll 132 and it is also obvious that the
said upright rolls D D and the top roll B' are preferably adjusted simul-
taneously relative to the works path, and I have discovered that the said upright
side rolls, in adjusting them apart simultaneously with the adjustment of the
top roll must be moved more rapidly than the top roll in order to avoid crop
ends and torn or cracked flange edges on the finished product.
It is well known by those skilled in the art that the extensions of the web in
the finished product, beyond the ends of that portion of the product that is prac-
tically perfect and called crop ends in the trade are cut off and worth no more
than scrap material, and it will, therefore be observed that any device or means
instrumental in reducing the length of the crop ends from several feet to a few
inches is of no inconsiderable importance. Crop ends should be avoided, if
possible, and this is practically accomplished in the mill that forms the subject
imatter of this invention as will hereinafter more fully appear.
I have found that the best results are obtained by moving rolls D and D
about one and one fourth times as fast as the movement of the top roll B', during
the adjustment of said rolls. It is obvious that the rolls at the commencement
of the operation of the mill are set as required to accommodate the passage
between them of the heated blank and generally in the first pass of the work little
more is accomplished than the straightening of the blank.
I would here remark that if the rolls ID', in their movement toward and
from each other, were travelling at the same rate as the travel of the top roll
toward and from the bottom roll, all of said rolls will have travelled the same
distance, and if, for instance, the rolls were set, say for a finished product to have
one half inch thickness of web and a half inch thickness of flange,
the top horizontal roll B would, at the completion of the work
be brought within that distance of the bottom horizontal roll, and
the side rolls D D₁ would be brought within that distance of the ends
of the horizontal rolls that form, as already indicated, the inner sides of the
flanges or heads and web of the work. Now, if the top roll, in its movement
toward the bottom roll, moves at the same rate that each of the side rolls move,
in the latter's movements towards each other, and if the top roll's travel during
the rolling of the work is two and one half inches, it follows, that after the top
roll has travelled two and one half inches, all of the rolls (B' D D¹) will have
travelled the same distance, and the top roll 13 will be three inches from the
bottom roll B2, and the side rolls D D' will be the same distance, namely, three
inches from the flange rolling surfaces of the horizontal rolls B₁ B2. Now, it is
evident that if an even reduction of all parts of the work is to be effected, and
the travel of the top and side rolls, during the adjustment of the said rolls,
were the same, not only had no allowance been left for overcoming the distortion
caused by the shear in cropping or cutting the blank, which is always much
greater on the flanges than on the web, but long crop ends will be had on the
finished product. This subject of long crop ends will be readily under-
stood upon consideration of the fact that the flange rolling surfaces of the hori-
C

page_text: zontal rolls B1 B2 always revolve more slowly than the peripheral or web rolling
surfaces of said rolls, because the flange rolling surfaces of said rolls extend
nearer to the axes of the rolls than the latters web rolling surfaces, and if the
side rolls D D¹ are not caused to work more vigorously than the horizontal
rolls the finished product will probably be found cracked or torn at the edges
of the heads or flanges, and a great deal of material, that should be equally or
properly distributed between the web and flanges and thereby increase the length
of the perfect product, will have been robbed by the web rolling surfaces of the
horizontal rolls to form extensive elongations of the web at the ends of the
product, which elongations or crop ends have to be cut off and are not worth
any more than scrap material, and if the edges of the flanges or heads are muti-
lated the whole product is practically worthless and forms very expensive scrap.
Instead therefor of desiring only to reduce the flanges at the same rate as the
web I have found it invaluable to reduce the flanges considerably faster than
the web in order to make up for the much slower rate of delivery at the points
of the horizontal rolls from which the edges of the flanges are delivered from
the speed of those parts of the horizontal rolls at which the web is delivered, and
when the side rolls 1) ]) are adjusted toward each other more rapidly to the
extent required than the movement of the top roll B₁ relative to the bottom
roll B2, it will be found that cracking or tearing of the edges of the flanges of
the product will always be avoided. Hence, by travelling the side rolls about
twenty five per cent. more rapidly, in the setting of the said rolls, than the top
roll, in the aforesaid two and one half inch travel of the top roll during the
reduction of the work, there will be room for the admittance of say at least
tree eights of an inch more material into each of the flanges, and a further
allowance of one fourth inch to a side to accommodate any distortion of the
blank or work, and the latter can be finished without torn or cracked edges and
without long crop ends on the finished part. The additional material going
into the flanges, it will be observed, is instrumental in adding to the length of
the finished product (flanges as well as web) and is not robbed by the web for the
objectionable purpose already indicated.
Before referring to the mechanism employed for effecting the adjustment of
said adjustable rolls B D and D', I would remark that live surfaces should be
present to all sides of the work, and consequently all of said rolls and the bottom
roll B2 should be rotated positively and in unison. A suitable operative con-
nection between each of said upright rolls D and D' and the adjacent trunnion
of the upper horizontal roll B₁ comprises, preferably, a horizontal friction disc d
(see Figs. III, and IV) operatively connected with the respective upright roll
in any approved manner and preferably by the formation of interlocking lugs
and D³ upon said friction disc and the roll, respectively. The upright roll is.
bored centrally, as at 1 (see Fig. IV) and the lugs D are formed upon the
upper portion of the surrounding wall of said bore. The friction disc is, therefore,
arranged within or extends into the upper portion of the bore through the roll,
and the aforesaid interlocking lugs are arranged vertically to accommodate an
up and down movement or adjustment of the friction disc for the purpose herein-
after made more apparent. Said friction disc d, at its other end, is provided
with an external annular friction surface that is frictionally engaged by a
corresponding annular friction disc 133 formed upon, or operatively connected
with, the adjacent trunnion of the upper horizontal roll B
The two friction discs B are reversely arranged and engage the inner or
oppositely located extremities, respectively, of the different friction discs d. d,
respectively, so that the two upright rolls DD' shall be driven in opposite directions,
and in the direction necessary, to render said upright rolls instrumental, as required,
in feeding the work between them and between the horizontal rolls. By means of the
vertical adjustability of discs & frictional engagement is maintained between said
friction members and the friction discs B3, upon vertically readjusting the upper
horizontal roll B₁, that, it will be observed, is supported from the said discs.

page_text: The means acting to elevate each friction disc d and maintain frictional
engagement between said friction disc and the engaging friction disc B³, com-
prises, preferably, a piston E (see Fig. IV) that is secured to the said disc din
any approved manner. The piston extends downwardly into the chamber f
formed in the vertical cylindrical lug or cylinder F formed upon the inner end
of a horizontally arranged slide H, and upon said cylinder the upright roll, that
is operatively connected with the aforesaid friction disc d, is mounted.
A port
or passage way f¹ for conducting water or fluid under pressure to chamber f, is
formed, in any approved manner, within the lower head of said cylinder, and
communicates with the aforesaid chamber. The fluid under pressure, within
said chamber, acts to force the piston upwardly and thereby causes the hori-
zontal friction disc d to be held in frictional contact with the engaging friction
disc 13, and supports the top roll B¹. A stuffing box F is provided around
the piston at and supported by the upper end of cylinder F, and prevents upward
leakage of the fluid under pressure from chamber f. Each housing G, near its
lower end, and at the top of the trunnions of the lower horizontal roll, (see
Figs. III and IV) is provided with laterally and outwardly projecting brackets G¹
that are provided with suitably constructed slideways G designed for slides H
and arranged parallel, therefore, with the direction in which the side rolls D
and D are adjustable. That is, two horizontally movable slides H H are
arranged at the outer sides of the different housings, respectively. One of said
slides carries roll 1 and the other slide carries roll D. Both slides H H are
adjustable toward and from each other, and the two rolls D D' are moved, there-
fore, toward or from each other according as slides H H are actuated
toward or from each other. Each slide H is provided, preferably, with two
screws H2 arranged parallel with the slideways for said slide and a suit-
able distance apart, and operatively connected with the slide in any approved
manner. Screws H engage, preferably, correspondingly threaded nuts I con-
fined or held stationary within recesses g¹ formed in the outer sides of the afore-
said slideway forming housing brackets, and by this construction, it is obvious
that each slide H and the roll supported thereby are adjusted toward or from
the pair of horizontal rolls B¹ B3 according as the engaging screws are turned
in the one direction or the other.
·
Each slide is provided, also with a thrust bearing J for the upright roll,
which bearing is constructed in any approved manner.
The upright screws L L (see Figs. I, II, and IV) engage correspondingly
threaded holes formed in the tops of housings G G, and are arranged to form
stops that limit the upward movement or elevation of the upper horizontal roll 13¹.
Saddles are interposed between the lower ends of said screws and the trunnions
of said roll, and one of the said saddles is shown and marked in Fig. II. By
this construction, it is obvious that upon turning screws L in the direction
required to elevate them, the upper roll B will be elevated by the action of
the fluid under adequate pressure upon pistons E, and upon turning the said
screws in the opposite direction the said roll will be lowered against the said
pressure.
My present invention involves broadly the required greater reduction of the
space between the side rolls than between the top and bottom rolls, during the
setting of the said rolls, and specifically embraces not only the travel of the
side rolls D D more rapidly than the movement of the top roll B₁ in the simul-
taneous adjustment of said rolls, but embraces also any device mechanism or
apparatus whereby the screws L instrumental in adjusting the top roll vertically
and the screws H³ employed in adjusting apart the side rolls are operatively
connected together in such a manner that they are shifted endwise simul
taneously, and at the same time the side roll adjusting screws are shifted more
rapidly so that rolls D D shall be moved more rapidly than roll 131 in setting
said rolls, and to this end in the case illustrated, the threads of screws H2 have

page_text: twenty five per cent. more pitch than the threads of the screws L, as shown in
Fig. VII.
A
The mechanism employed for rotating screws L and H2 is, preferably, as
follows: Upon the upper end or portion of each screw L (see Figs. I, II
and IV) is operatively mounted a worm wheel L' that meshes with a worm M¹
formed upon a suitably supported horizontally arranged shaft M. The upper
ends of screws L, are in the case illustrated, angular in cross section and extend
through corresponding holes in the central portions of the engaging wheels L'
so that the said screws are capable of endwise movement independently of the
said wheels L' without interrupting operative connection between the said
wheels and screws. Upon the outer end of each screw H2 of a slide H (see
Figs. I, III, and IV) is operatively mounted a bevel gear h² that meshes with
a bevel gear h³ operatively mounted upon horizontally arranged shaft h* sup-
ported from brackets H10 that are rigid with the said slide. Shaft M is inter-
geared, as at m (see Fig. 1) with the reversibly rotatable shaft m¹ of an electric
motor m². Each shaft his operatively provided, also, with a worm wheel h
that meshes with a worm he formed upon an upright shaft h that, at its lower
end, is supported from a bracket h" rigid with the adjacent slide H, and, .at
its upper end, is supported from a standard H2 rigid with the said slide.
bevel gear his operatively mounted upon the upper end of the said shaft h³
and meshes with a bevel gear m8 mounted operatively and slidably, by means
of groove and feather m³ upon the shaft M, and said gear is carried by the
aforesaid standard H12. By the construction just described, it is obvious that
the mechanism establishing operative connection between the shaft M and the
screws of each slide H is carried by and movable with the said slide. By the
construction just herein before described it will be observed that all of the said
screws L and H2 are operatively connected with one and the same motor shaft m',
and are consequently movable in unison. All the gears and worm wheels of the
mechanism that establishes operative connection between shaft M and the said
screws correspond diametrically, and the worms of the said mechanism corre-
spond in diameter, so that all the screws are rotated at the same speed when
they operate. Hence, in the case illustrated, the more rapid endwise movability
of screws H2 is due solely to the greater pitch of the threads of the said screws.
Of course, the members of the mechanism establishing. operative connection
between the reversible shaft m¹ and screws H2 and L àre preferably so arranged
that the side rolls D D and top roll B shall be simultaneously shifted inwardly,
or outwardly, according as the said shaft is rotated in the one or the other
direction and the said rolls are set as required, at the commencement of the
operation of the mill upon a predetermined size of blank, to form the initial
passage way, between the said side rolls and between the top and bottom rolls
for the said blank, and the said adjustable rolls are adjusted as required to
reduce the said space after each subsequent pass of the said blank. I would here
remark that so far as concerns the shifting of slides H simultaneously with
and more rapidly than the shifting of the top roll B¹, my invention involves,
broadly, any mechanism for accomplishing the said result.
Rolls A and A* of roll system A (see Figs. I and II) are, of course, arranged
in the same vertical plane, and roll A¹ has its trunnions resting in half boxes A
movable up and down within the two upright housings As that are arranged at
opposite sides, respectively, of the works path. Half boxes A rest upon and
are consequently supported from any suitable number of upright bars or rods A
(see Fig. VI) operatively connected, at their lower ends with vertically tilting
weighted levers A7 whose weights A8 somewhat more than counter balance. the
weight of roll A¹ and act in the direction required to elevate said roll. Saddles
or blocks A rest upon the trunnions of roll A¹ above half boxes A4, and suit-
ably operated screws A engage correspondingly threaded holes in the tops of
the housings and engage the upper surfaces of saddles A and not only limit
the upward movement of roll A¹ but are instrumental in lowering the said roll

page_text: against the action of weights A8. Roll A¹ is adjustable vertically, therefore,
as required preparatory to operating upon the edges of the heads or flanges of
a predetermined piece of work. Screws A10 when they are rotated or turned,
are operated uniformly, and the mechanism employed for uniformly operating
said screws comprises, preferably two beveled gears Aª A" operatively mounted
on the different screws, respectively, above the housings, and meshing with
beveled gears Ab that are operatively mounted upon a horizontally arranged
shaft A suitably supported above the housings, and the arrangement of said
last mentioned gears relative to gears A is such that the screws, when the said
shaft is rotated are simultaneously turned in the same direction.
A gauge for regulating the width of the heads or flanges of the work is pro-
vided and comprises, preferably a collar i (see Figs. I and II) mounted upon
the bottom roll A* of roll system A, at the under side of the path of and
arranged to afford bearing for, the web of the work, between the paths of the
work's flanges or heads. The central portion of roll A is provided, preferably
with an annular groove or recess Ad and collar i is mounted upon roll A within
the said recess.
Said collar, therefore, affords bearing, as already indicated, för
the work during the operation of rolls A' and A*. The side walls of recess Ad
prevent endwise displacement of the collar upon roll A, and the portions of the
roll A, at opposite sides, respectively, of said recess are instrumental, when
they are engaged by the work, in operating upon the edges of the heads or
flanges of the work. One of the rolling portions of roll A is keyed, as at A
(see Fig. II) or otherwise removably secured, to the remaining portion of the roll,
to accommodate the mounting of collar i upon the central reduced portion of
the roll and, of course, said keyed part of the roll is not applied until after the
collar has been placed in position. Collar i is adjustable vertically as required to
enable it to be lifted or elevated a suitable distance after each pass of the work
and thereby render roll A¹ capable of operating as required upon the upwardly
presented edges of the work's flanges or heads. The vertical adjustability, of
collar is obtained preferably by having the collars hole i¹ through which the
central portion of roll A* extends, elongated vertically, as shown in Fig. II.
Roll A is supported from housings A, in any approved manner, and collar i
is supported, preferably, by a saddle 22 arranged below the collar and having
its upwardly facing surface arranged circumferentially of and concentrically
with the collar, and anti-friction rollers are interposed between said surfaces
of the saddle and the lower external surface of the collar that turns upon said
rollers during the operation of the mill. Saddle has two sides arranged
at opposite ends, respectively, of the collar, and the antifriction rollers ex-.
tend between and are supported from said sides. The means employed for
adjusting or moving collar i vertically comprises, preferably, an upright screw
that extends through and engages a correspondingly threaded nut that is
located a suitable distance below saddle and rendered stationary in any ap-
proved manner. A suitably supported worm wheel is operatively connected
in such a manner, for instance, by feather and groove 28, with screw that the
latter can move endwise independently of the said wheel without interrupting
operative connection between said wheel and said screw 25. Worm wheel
meshes with a worm that is formed upon a suitably supported horizontally
arranged shaft 20 (see Figs. I and II) and shaft 10 is intergeared, as at ", with
a suitably supported shaft 2, that extends diagonally to shaft M and is inter-
geared, as at 13, with the said shaft M.
It will be observed, therefore, that screw 25 is operatively connected with the
motor shaft m¹ so that the setting or adjusting of collar i preparatory to each
pass of the work for the purpose, as already indicated, of gauging or controlling
the width of the work's flanges, is effected simultaneously with the adjustment
of the adjustable rolls of roll system B. Worm wheel 7, worm and gears 213
correspond diametrically with the worm wheels, worms and gears that officiate
in establishing operative connection between shaft M and screws L H³, so that

page_text: screw is rotated at the same speed 'as screws H2 and L. Therefore if collar
is to be shifted about one hálf-as far as the top roll B₁ of roll system B, as
desired, it follows that the threads of screw 25 (see Fig. VII) have fifty per
cent. less pitch than the threads of the screws L employed in adjusting the said
roll.
The said collar or cylinder i will; therefore, in shifting rollers B and D D',
raise one half as much as the said roll B₁ lowers; and this is desired inasmuch
as the position of the said member i determines the width of the work's flanges.
As the rolls B B dig into the web of the blank or work, the distance between
the upper side of the works web and upper roll A¹ is increased in proportion,
and this being the case, although there is no collar or cylinder i on said roll A',
still, as the work, that is being operated upon, can be turned at will, as will
hereinafter more fully appear, it follows that the distance between member i
and roll A¹, for the initial pass of the work, is determined by the position of
the roll A relative to the position of the said member i, and this distance is
increased or decreased, for the work's initial pass, by raising or lowering the
said roll A¹, according as wider or narrower flanges or heads upon the finished
product are desired. The lowering of the top roll B₁ of roll system B will result
in raising member i one half of the distance travelled by the said roll'B1, and
member will consequently gauge or control the width of the work's flanges
or heads after the mill has commenced to operate. The function performed by
member is, therefore, primarily, the gauging of the width of the works heads
or flanges, and as the work is turned over at suitable intervals, as will presently
appear, it follows that the edges of the flanges of the finished product will be
even.
I would here remark, however, that my invention embraces broadly, a gauge
forming collar or cylinder on either one of the flange edge rolling rolls and
arranged to engage the work's web between the flange edge rolling portions of
the said roll, and my invention, so far as rolling of the work's flanges is con-
cerned, embraces, also, and broadly, a reduction of the space between the said
collar or cylinder and the roll relative to which the said cylinder or collar is
adjustable less to the extent required than the reduction of the space between
the top and bottom web reducing rolls B 132, in the setting of the said adjustable
members after a pass of the work and before the work's next pass.
.
In other words, I would have it understood that although I consider the details
of construction, illustrated and described in this application, desirable and
valuable my invention is not limited to the said details, but embraces any means
suitable for accomplishing the desired results herein enumerated.
The diagonal shaft 7 is made, preferably, in two sections arranged end to
end and provided, at their adjacent ends, with a clutch that has one of its parts 15
fixed to the shafts upper section and has the companion part 216 operatively and
slidably mounted upon the shafts lower section. The slidable clutch member
is shifted in any approved manner to cause it to operatively engage or disengage
the companion clutch member. Suffice it to state here that operative connec-
tion between screw and the shaft M is established or interrupted according as
the said clutch is rendered operative or inoperative, and the operation of the said
screws is, therefore, under the control of the operator.
The rollers and, (see Figs. I and II) arranged transversely of the lower
side of the work's path, at opposite sides, respectively, of roll A*, are instrumental
in guiding the work to and from said roll system A, and the roll j¹ that is located
between the said roll system A and table C2 is a feed roller that is suitably
driven in the direction required to feed the work to and from the said roll
system from and to the said table. The said table comprises any suitable number
of feed rollers C, as already indicated, and the feed roller at the inner end of
the table is operatively connected, by means of sprocket wheels and chain C5,
with feed roller ¹. Operative connection between the feed rollers of the table
is established, preferably, by shafting and gears C6 suitably driven to feed the
work in the direction required (see Fig. I). To remove scales from the work,

page_text: that can be readily removed by a tumbling process, the work, when it is upon
table C, is automatically overturned any suitable number of times, and this
process of tumbling the work is valuable also, as already indicated, to insure
adequate operation on all of the edges of the work's flanges in roll system A.
The
The means employed for overturning the work upon table C2 comprises,
preferably, (see Figs. VIII and IX) an oscillating shaft C7 that is suitably sup-
ported below and arranged horizontally and longitudinally of the table, and is
provided at two points, located a suitable distance apart, with two arms C8 C8
extending transversely of the table, and arranged to engage the work upon the
table from below and throw the work laterally against the inclined uprights or
backs (with which the table is provided. Each arm C8 of shaft C7 is arranged
to operate between two adjacent feed rollers of the table so that said rollers
shall not interfere with the location and operation of said arm. Arms 08 in
their normal or inoperative position, are below the path of the work that, in
solid lines Fig. IX. is shown resting upon the feed rollers of the table, and, in
dotted lines in same figure, is shown thrown laterally against the inclined sur-
faces of backs C, which inclined surfaces extend upwardly and outwardly from
their lower extremities. Each arm C8 has its outer portion bent or extending
upwardly, so that said outer portion, when the work is thrown against backs 09,
shall over lap the work and prevent the latter from rebounding into the same
position upon the table, and the inclined surfaces of members C are sufficiently
far from a perpendicular that the work, when the work tumbling arms are
returned below the table, will fall with its opposite side upon the table.
said over turning operation is repeated, if desired, any suitable number of times,
and is very effectual in shaking scales from the work. The means for oscillating
the work over turning shaft C7 comprises, preferably (see Fig. IX) a gear C₁o
that is operatively mounted upon the shaft, preferably at some point between
the two arms C8 C8 and said gear meshes with a reciprocating rack C" that is
arranged transversely of the feed table, between two adjacent feed rollers of
said table, and attached, in any approved manner, to the rod C12 of the pis-
ton C¹³ of a hydraulic engine or motor C. In order to render the action of the
extremities of arms C8 easy, in over turning the work upon table 0, each of
said arms, at its outer end is provided with a wheel or rollers C15 that engages
the work in the over turning operation and prevents the arm from holding
onto or detaining the work during the said operation, and, in order to render
the over turning of the work still more positive, and positively insure the over
turning of the work during the over-turning operation of the said arms C8,
one or more hydraulic cylinders C16 are provided. In the case illustrated two
cylinders C16 are arranged at a suitable distance apart and at right angles to
table C at the rear of backs C. Each cylinder C₁ is provided internally with
a piston C capable of reciprocating endwise of the cylinder's chamber and
actuated by fluid, under pressure, admitted to the cylinder in any approved
manner, and the said piston has its rods C18 extending forwardly, and the said
rod, when actuated forwardly, engages the lower portion of the work from the
rear, and participates in the over turning of the work and renders the over
turning operation infallible. C19 designates a forward side guide for the work
in the latter's passage over table C and is, of course, arranged along the' for-
ward side of the work's path. The forward or outer end of each rod or push-
ing device C18 is provided, preferably, with an upright arm C20 that is pivoted
horizontally and transversely at C to the said rod, and at the rear of its axis,
is provided with a weight or poise, C that acts to retain arm C in the latter's
upright or normal position. The said weight C normally straddles the rod C18
and engages the upper side of the rod, and the said arm cannot therefore, tilt
rearwardly beyond its normal position. The arrangement of parts is such that
the said arm, when in its normal position, projects above the table far enough
to engage upon being actuated forwardly the lower portion of the work thrown
against back C and participate in over turning the work upon the said table,

page_text: and the work when overturned tilts the said arm forwardly and downwardly
out of the way if the said arm is struck by the overturning work, and hence
the said arm is not injured in case it is struck by the overturned work.
Two suitably formed bottom guides or bearings Q Q', (see Figs. I and II)
for the work are provided at opposite sides, respectively, of rolls B B2 of roll
system B at the under side of the path of the work. Guide Q' is arranged
between roller j and roll B2 and extends into close proximity to the said roll B².
Guide Qis arranged between roll B2 and table C₁ and extends into close
proximity to the said roll. Said guides prevent downward displacement of
the work in the latter's passage to and from roll system B.
A top guide T for the work in the passage of the work from the roll system B
to the roll system A is provided (see Figs. I and II) for the purpose of pre-
venting the work from being thrown upwardly out of its path in said passage.
Said guide consists, preferably, of an approximately horizontally arranged
heavy plate suspended over and in close proximity to the path of the upper side
of the work's web and between the paths of the works flanges. Guide T is
located between the two roll systems and in close proximity to roll B' of roll
system B. Guide T is movable vertically to accommodate its adjustment corre-
spondingly and simultaneously with the vertical adjustment of the top web
reducing roll B. To effect the movement of guide T simultaneously with and
in the same direction as the vertical movement of roll B₁ and to prevent any
injury to any parts by any upward blow received by said guide from the work
in the passage of the work below the guide, the following construction is pro-
vided the guide, at or near its central portion, is suspended by means of a rod
or bar T that depends from one end of a vertically tilting weighted lever T2 and
is attached, at its lower end, to the guide in any approved manner. Lever T2
is supported from a vertically movable slide 13 that extends between, and
engages vertically slideways (not shown) formed upon housings G G. The
said lever is fulcrumed, therefore, to any suitable member that is rigid with or
supported from the said slide, that near each end is suspended from a pis-
ton T (see also Fig. XI) arranged to operate within and endwise of an upright
stationary cylinder T having closed ends. Two upright cylinders T5 T5 are
provided, therefore over opposite ends, respectively of slide 13 and the latter
is suitably attached to the piston rods T6 depending from the pistons within
said cylinders. Each cylinder T5 (see Fig. XI) is provided with two lateral
ports T and Ts at the upper end and the lower end, respectively, of the cylinder.
The lower port T8 connects the lower extremity of the cylinder's chamber with
a pipe or pressure linė T employed in supplying water or other fluid under
adequate pressure into said chamber below the piston in said chamber. The
fluid pressure upon pistons T from below acts to lift guide T, and I would here
remark that the poise T10, with which lever T3 is preferably provided, counter-
balances preferably the aggregate weight of the guide T and the connection
between the lever and the said guide. Adjacent to each cylinder Tǎ is provided
another stationary upright cylinder T" that is preferably integral with the said
cylinder T5 and is closed at its lower end and open at its upper end. A piston T¹2
is arranged to operate within and endwise of each cylinder T, and the latter,
at its lower end, is provided with a lateral port T3 that is required in the
establishment of open relation between the lower extremity of the chamber of
the said cylinder and the port T7 of the adjacent cylinder T. The cylinders T5
above the pistons therein, the cylinders T below the pistons therein, and the
connections between ports T and T13 are supplied with water or other suitable
fluid from any suitable number of supply pipes T. Each piston T has its
rod T extending downwardly below the cylinder and operatively connected
with an arm projecting laterally from and rigid with the saddle upon the
adjacent trunnion of the top web reducing roll B¹. The said piston T2 and
consequently the guide T, will therefore move downwardly correspondingly with
any downward travel of the top web reducing roll B. It is obvious that, as already

page_text: indicated, the top web reducing roll B₁ and with it the flange reducing
rolls D D', are set, preparatory to the first pass of a heated blank that requires
reducing the distance apart required for the first pass, which distance forms
the largest work receiving passage between said rolls during the reducing opera-
tion upon the blank, and said passage is rendered smaller preparatory to each
successive pass of the work. It follows, therefore, that the work's top guide T
must be correspondingly set preparatory to every pass of the work.
The opera-
tive connection of pistons T2 with the saddles 7 on the top roll B lowers the
said pistons T2, as already indicated upon lowering the said roll B, and water
is thereby displaced from below said pistons in cylinders T into the upper ends
of cylinders T, through the connections between said cylinders, and the water
forced into said cylinders T5 depresses the pistons T against the power exerted
by the water from the pressure line, and thereby lowers the guide the distance
required. Guide T bears against or abuts the under side of slide T3, as at T16
(see Fig. II), so that the guide cannot tilt. After the work has had its finishing
pass, the rolls are again adjusted to enlarge the work receiving passage between
them as required for another blank, and the elevation of the top roll B during
said resetting of the rolls by the pressure upon them by the horizontal friction
discs d as soon as the screws L are backed up, lifts pistons T2, permits the dis-
placement of water from the upper ends of cylinders T5 into cylinders T" and
accommodates the elevation of pistons T+ by the power from the pressure line,
and thereby results in the corresponding elevation of the work's top guide T.
It will, therefore, be observed that said guide is adjusted simultaneously and
uniformly with the adjustment of the top roll B¹. It is desirable to lock the
said roll and the said guide in the desired adjustment, so that they cannot be
displaced vertically during the pass of the work, and I interpose, therefore, a
valve (see Figs. I and XII) in the line of the pipe connection between
cylinders T5 and T which valve controls continuity in the passage way between
each cylinder T and the adjacent cylinder T. When, therefore, said valve is
closed water cannot pass between the said cylinders, and the said top roll and
the said guides are locked against vertical displacement, and when the said
valve is open water can pass between the said cylinders and accommodate the
vertical adjustment of the said guide and roll. It is obvious, therefore, that
valve should be opened simultaneously, or practically simultaneously, with
the commencement of the endwise shifting of screws L and should be closed
simultaneously, or practically simultaneously, with the cessation of the end wise
movement of the said screws. Before proceeding to describe the mechanism
preferably employed for operating valve V, I would remark that said valve is
arranged, preferably in a valve casing V₁ having a port V2 connected, by means of
a tee V3 with the two pipes V4 V. One of said pipes V connects with the port T¹³
of one of cylinders T and the other pipe V4 is connected with the port T13 of
the other cylinder T. The seat V5 for the valve is formed at the inner end of
said port V, and the latter, at its inner end, connects with a passage way V6
extending through the valve casing and having its opposite ends connected with
different pipes V7 V7 respectively. One of pipes V7 connects with the port T
of one of cylinders T5 and the other pipe V7 connects with the port T
of the other cylinder T5. By this construction, it is obvious that, when the
valve is shifted off its seat, open relation is established between cylinders T5
and T, and said communication is interrupted when the valve is seated.
The valve V for establishing and interrupting communication between the
chambers of adjacent cylinders T and T has a stem V8 extending outside of
the valve casing and operatively connected at its outer end (see also Fig. X), '
with a tilting lever V at any suitable point between the opposite ends of the
lever that is fulcrumed, at one end, as at V10, to any suitable support and at
its opposite end is operatively connected, by means of a rod or suitable con-
nection with the endwise movable core or cores of a solenoid V12. A suit-
ably applied spring V13 acts to retain the core or cores of the solenoid in their
D

page_text: outer or normal position and also acts to retain the valve V in its closed position,
wherein the chambers of adjacent cylinders T and T are not in open relation
with each other and water cannot flow between said chambers as already indi-
cated. However, when an electric current traverses the solenoid, the core or
cores of the solenoid are moved against the action of the said spring and move
lever V9 in the direction required to open the valve whereupon communication
between said chambers is established as required to accommodate the flow of water
from cylinders T5 to cylinders T", or vice versa, according as roll B' is elevated
or lowered. An electric current is caused to traverse the solenoid, therefore,
in any approved manner, simultaneously, or practically simultaneously, with
the commnencement of the operation of screws L L, so that the said cylinders
shall be placed in open relation with each other simultaneously, or practically
simultaneously, with the commencement of the operation of said screws, and the
said solenoid is rendered inactive, in any approved manner, simultaneously, or
practically simultaneously, with the cessation of the operation of screws L L so
that communication between the said cylinder shall be interrupted simul-
Faneously, or practically simultaneously, with the cessation of said screws opera-
tion. A desirable manner of simultaneously, or practically simultaneously
effecting operation of the solenoid and electric motor, and thereby move valve V
simultaneously with the commencement of the said screws operation, involves
the arrangement of the solenoid and motor in series in one and the same electric
circuit, as shown in Fig. X, and the electric current is controlled and reversed
at pleasure by any approved controller having a current reverser incorporated
therein. Devices for controlling an electric current, and reversing the latter's
direction, and the placing of electro receptive devices in series are so well under-
stood by those skilled in the art that the largely diagrammatic illustration in
Fig. X will be readily understood, and further description or illustration thereof
in this application is considered unnecessary. The connection of the electric
motor and solenoid in series is important, therefore, because a disabling of
either one of said electro receptive devices would at once interrupt the flow of
electric current, and simultaneously, or practically simultaneously, interrupt the
operation of the other electro receptive device, and consequently there is no
liability of the operation of the screws when valve V is closed, nor is there any
liability of the closing of the valve while the screws are operating.
Two side guides rr for the work (see Figs. I, II and III) extend from roll
system B to and beyond roll system A, and are arranged at opposite sides, respec-
tively, of the work. Said guides extend into close proximity to the rolls
of roll system B and are cut at the top, below roll A¹, as at ¹, to accommodate the
location and operation of the said roll A¹. Guides rr extend a suitable distance
beyond the outer side of roll system A into suitable proximity to table C².
Guides are parallel, supported in any approved manner, adjustable or mov-
able laterally, and operatively connected, by suitably applied bars, rods or
devices, at points between roll system B and roll systemi A, with slides H
and H, respectively, and hence said guides are moved apart or toward each other
according as rolls D and D1 are shifted toward or from each other, and simul-
taneously with and to the same extent as the movement of the said rolls D D'.
The said guides ṛ r, between roll system A and table C2 are engaged, upon their
outer sides, by extensions or members of pistons 4 (see Fig. I) arranged
and operated as required to
the
ends
said
of guides
toward each other simultaneously with the shifting of rolls B' D D' and guide T.
Guides are set as required for the work's initial pass to accommodate the pas-
sage of the heated blank between them, and after the first pass the said guides
are shifted toward each other preparatory to each pass, to reduce the width of
the passage way between them and continue to properly perform their function
of guiding and preventing lateral displacement of the work during the opera-
tion of the mill upon the work. One meniber 3 engages and is arranged at
the outer side of and at right angles to one of the guides r, and the other mem-
move
7°
r

page_text: ber engages and is arranged at the outer side of and at right angles to the
other guider. Each piston is arranged to operate within a stationary hori-
zontally arranged closed chambered cylinder that, at its outer end has its
chamber connected with a pipe employed for applying water or other fluid
under pressure to the piston in said cylinder, and thereby actuate the said pis-
ton in the direction required to move the engaging guider laterally and in-
wardly. Both pipes are connected with a main supply pipe by a valve
casing 8, and a valve (see Fig. I) in said valve casing interrupts and establishes
communication between the main pipe and the branch pipes . The con-
struction of said valve and valve casing is substantially the same as the
construction of valve V and valve casing V and the stem 10 of valve is
operatively connected with a vertically tilting lever that is fulcrumed at
one end, as at 13, to any suitable support, and has its opposite end connected
with the core or cores of a solenoid that is electrically energized in any ap-
proved manner and may be connected in series with the solenoid V12 and the
motor m². Valve may, however, be operated in a different manner, if desired,
and suffice it to state, therefore, that any suitably operated valve for controlling
the supply of pressure to cylinders is employed and is opened to admit pres-
sure or additional pressure to the said cylinders simultaneously, or practically
simultaneously, with the inward shafting of rolls B D D and guide T.
The arrangement of parts is such that when an electric current traverses
solenoid valve is opened against the action of means, such for instance as
a spring acting in the direction required to retain the valve seated. Fluid
can be removed within cylinders through valved drain pipes 15 with which
said cylinders are provided (see Fig. 1).
Two side guides R R for the work (see Figs. I, II, III and XIII) are provided
between table C and roll system B at opposite sides, respectively, of the works
path, and extend into close proximity to rolls B¹ B². Each guide R is sup-
ported from the adjacent slide H in any approved manner, and said guides are,
therefore moved toward or from each other according as the side rolls D and D
of roll system B are shifted toward or from each other. In the case illustrated,
each guide R is supported, at or near its inner end, at R', (see Fig. III), in any
approved manner, from the supporting slide H. but, at its outer end, is sup-
ported from the slide through the instrumentality of an endwise movable bar
or rod R2 (see Figs. III and XIII) that is supported from, and is movable with
as well as independently of the slide. Said bar extends through a suitably
constructed stationary chambered cylinder R³ that is closed, at its ends and rigid
with a lug G formed upon the adjacent housing G. The said bar extends
casily through said lug and loosely through a lug H³ formed upon the slide.
The outer end of the bar is round and screw threaded, and two nuts R6 R7 are
mounted upon the bar at opposite sides, respectively of the said lug H³ and
farther apart than the opposite ends of the said lug. The bar, within cylinder R³,
is provided with a piston R* arranged to move endwise of the cylinders chamber
and actuated inwardly, as required to press the attached guide R laterally and
inwardly, by water or fluid under pressure conducted into the outer end of the
cylinder, by a pipe R that communicates with the outer end of the cylinders
chamber. Nut Rs constitutes a stop that limits the outward movement of the
bar independently of the slide and consequently the bar in its normal position
has the said nut R6 engaging the lug H³ of the slide and is shifted inwardly
with the slide in moving the side rolls toward each other. The space between
lug H3 and the other nut R of the bar is the distance that the bar can move
independently of the slide and hence. the bar, when under endwise pressure by
the fluid introduced into cylinder R will press the attached guide laterally and
inwardly, and the two guides R R are pressed inwardly or toward each other
during the last pass of the work to restrict the passage way between the said
guides at bars R2 R³ to approximately the width of the finished product (measur-.

page_text: ing widthwise of the web) so as to insure that the finished product will,
practically, be perfectly straight.
It follows, therefore, that bars R2 R2 are located at the mill's end at which
the finished product is delivered, and the finishing pass is, preferably, from roll
system A to roll system B, as in the case illustrated
The two pipes R5 leading to the two cylinders R³ are connected with a main
supply pipe Rs that is provided with any suitably constructed three way valve R³
capable of establishing and interrupting communication between cylinders R³
and pressure line R8 and capable also of draining the said cylinder. The con-
struction of valves of the character indicated is so well known that detailed
description of illustration thereof is not considered necessary in this application.
