Improvements in Rolling Mills.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of 18, Bucking-
ham Street, Strand, W.C., Patent Agent, do hereby declare the nature of this
invention (a communication to me from abroad by Henry Grey, of New York,
County of New York and State of New York, United States of America,
Mechanical Engineer and Manufacturer), and in what manner the same is to be
performed to be particularly described and ascertained in and by the following
statement:-
This invention relates to improvements in mills or apparatus for rolling
metallic beams, girders, columns, and structural work generally.
The primary object of this invention is to obviate the necessity of employing
different roll collars, or rolls, in rolling different widths of flanges, and thereby
avoid the labor and loss of time whenever a change in the width of flanges, for
any given weight of beam or work, is desired, and to obviate the necessity of
turning the blank or work during the process of manufacture and thereby pre-
vent loss of heat during the process.
With this object in view, and to the end of providing novel and meritorious
means for preventing upward displacement of the work, and realizing other
advantages hereinafter appearing, the invention consists in certain features of
construction, and combinations of parts, hereinafter described and pointed out in
the claims:-
In the accompanying drawings, Fig. is a top plan illustrating the roll system
employed in operating upon the sides of the flanges and web of the work, and
another and novel and meritorious roll system employed in operating upon the
edges of the flanges. Portions are broken away in this figure to reduce the size
of the drawing and to more clearly show the construction.
Fig. 11 is a side elevation relative to Fig. I, partly in section. Fig. III is an
elevation mostly in section on line III-III Fig. I illustrating portions of roll
system B, and particularly the operative connection between the rolls D and
the roll B. Fig. IV is a vertical section on line IV-IV Fig. I looking in the
direction of the arrow. Fig. V is a vertical section on line V-V Fig. I looking
in the direction of the arrow.
Fig. VI is an elevation, partly in section of a vertically shiftable top-guide,
and mechanism employed in controlling the said guide. Fig. VII is an elevation
in section on line VII-VII, Fig. VI looking in the direction of the arrow.
Referring to the drawings, A designates a roll system for rolling the edges
of the heads or flanges of the column, beam, or girder that is hereinafter termed
"blank," section," "work or "product," and B represents a roll system for
rolling opposite sides of the flanges or heads and the web of the work. The two
roll systems B and A are arranged in line, and the rolling or operating surfaces
of the rolls of the two systems of rolls are driven positively, and in the direction
required to feed in opposite directions alternately, and the blank or work is given
as many passes, through the mill, as are required to complete the rolling or

page_text: shaping of the work, and the blank is in a suitably heated condition preparatory
to its introduction into the mill, and the work is fed through the mill with its
web arranged horizontally.
The roll system B (See Figs. I, II and III), comprises a top horizontal roll B',
a bottom horizontal roll 332, and two vertical side rolls 1) and D arranged at
opposite ends, respectively, of the said horizontal rolls. Roll B is arranged
horizontally and transversely of the works path, in position to operate upon the
upper side of the web of the work and upon the inner sides of the works flanges
or heads above the web. Roll B2 is arranged below and transversely of the works
path, in position to operate upon the lower side of the works web and upon the
inner sides of the works heads or flanges below the web. The two upright
rolls D and D are arranged at, opposite sides, respectively, of the works path, in
position to operate upon the outer side of the adjacent flange or head of the work.
The work is shown in position in Figs. II, III, IV and V.
The roll system A comprises a pair of rolls, 1 and 11 and another pair of
rolls 2 and 21. The two pairs of rolls are arranged side by side and a short
distance apart, and the pair of rolls 2 and 21 is arranged between the pair of
rolls 1 and 1 and the pair of web reducing rolls B₁ 132 of roll system B.
Rolls 1 and I are arranged at the top and bottom respectively, of the works path.
The roll 1 is arranged in position to operate upon the downwardly presented
edges of the work, and the roll 11 is arranged to afford bearing or resistance for
preventing upward displacement of the work during the operation of the roll 1.
Rolls 2 and 21 are arranged at the top and bottom, respectively, of the works
path. Roll 2 is arranged in position to operate upon the upwardly presented
edges of the works flanges or heads. The roll 21 is arranged to afford bearing or
resistance for preventing downward displacement of the work during the operation
of the roll 2.
Feed-tables not shown, of any improved construction, are provided at opposite
ends of the works path through the mill, and any suitable intervening supports
for the work, in addition to the support afforded by the aforesaid rolls, may be.
provided.
The work is passed in opposite directions, alternately as already indicated.
The mechanism or apparatus, preferably employed for positively driving the
aforesaid rolls, comprises the following:-
An engine shaft 4 is operatively provided with a gear 5 that is operatively
connected, in any suitable manner, with the trunnion of the bottom web reducing
roll B2, and the said gear meshes with a diametrically corresponding gear 6 that
is operatively connected, in any approved manner, with the adjacent trunnion
of the top web reducing roll. Hence the two web reducing rolls are driven at
the same speed and in opposite directions, respectively.
The engine shaft is operatively provided also with a bevel gear 7 that meshes
with a bevel gear S operatively mounted upon a suitably supported shaft 9 that
is arranged horizontally and at right angle to the engine shaft, and operatively
provided also, with bevel gears 10 and 11. Gear 10 meshes with a bevel gear 12
operatively mounted upon a suitably supported shaft 13 that is arranged
horizontally and parallel with the engine shaft and is operatively connected, in
any manner, with a trunnion of roll 21 and the adjacent trunnion of roll 2 is
operatively connected in any approved manner, with gear 15 that meshes with a
gear 14 operatively mounted upon the shaft 13. The gear 11 meshes with the
bevel gear 16 operatively mounted upon the suitably supported shaft 17 that is
arranged horizontally and parallel with the shafts 13 and 4 and operatively con-
nected, in any suitable manner with a trunnion of roll 1, and the adjacent trunnion
of roll is operatively connected in any approved manner with the gear 19
that meshes with the gear 18 operatively mounted upon the shaft 17.
The arrangement of the parts, that. establish operative connection between
the said rolls and the engine shaft, is such that all of the said pairs of rolls shall
be driven in the direction required to feed the work in the one direction or the

page_text: other according as the engine shaft is driven in the one or the other direction.
It will be observed, therefore, that the two web reducing rolls, B1 and B2 are
driven in opposite directions, respectively, as already indicated; that the upper
web reducing roll and the lower web reducing roll are driven in the same direction
as the upper rolls and lower rolls, respectively of the roll system A; that the
work can be fed from and between the rolls of the pairs of rolls of the roll
system A, to and between the rolls of roll system B, or vice versa, according as
the engine shaft is rotated in the one direction or the other, and, preferably, the
relative arrangement of the two roll systems, and the relative arrangement of the two
pairs of rolls of the flange edge rolling rolls are such as will enable the work,
in the latter's passage through the mill to be operated upon by another pair of
rolls before it has left an operating pair of rolls.
The lower web reducing roll B is suitably supported from the two housings GG
that are arranged a suitable distance apart at opposite sides, respectively, of the
works path. It is obvious that, for work of the character indicated, one or both
of the 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 1 is shiftable vertically.
It is obvious, also that the rolls, at the commencement of the operation of
the mill, are set as required for the first pass of the heated blank.
Before further reference to the adjustment of the rolls B, D and D, I would
remark that live surfaces should be present to all sides of the work, and, con-
sequently, all of said rolls and the bottom roll 12 should be rotated positively.
A suitable operative connection between each of the upright rolls D and I) and
ihe adjacent trunnion of the upper horizontal roll B₁ comprises, preferably, a
horizontal friction disc (see Fig. III) operatively connected with the respective
upright roll in any approved manner and preferably by the engagement of
lugs formed upon and depending from the discs into recesses I formed in
the roll, and friction discs d are frictionally engaged by friction collars 133
formed upon or operatively connected with, the trunnions of the roll B. The
vertical adjustability of discs & accommodates the maintenance of frictional
engagement between the said discs and the friction collars B3. The arrange-
ment of the frictionally engaging surfaces of members and 133 is such that a
desirable adequacy in the contact is maintained between the said friction members
during the adjustment of the vertical side rolls toward and from the horizontal
rolls and during the adjustment of the top web reducing roll toward and from
the lower web reducing roll. The means acting to elevate each friction disc d
and maintain frictional engagement between the disc and the engaging friction
collar 13 comprises preferably a piston E that is secured to the disc in any
approved manner. The piston extends downwardly into the chamber f formed
in a suitably supported slide H that carries the side roll that is operatively
connected with the said disc. The chamber is provided with an inlet flat
which fluid under pressure is introduced to the lower end of the piston. This
fluid acts to force the piston upwardly and thereby causes the disc d to be held in
frictional contact with the engaging friction collar 133, and can if desired assist in
supporting the top roll B. As already indicated, each side roll 1) is carried by a
slide H. The slides H H are movable toward and from each other, and, con-
sequently, the two rolls D D are adjustable toward and from each other. The
mechanism for shifting the rolls D D toward and from each other, and the means
employed in maintaining operative connection between the rolls D D and the
roll B³, form no part of the present invention and further illustration thereof and
reference thereto in this application is not considered necessary.
The upright screws L L (see Fig. III) engage correspondingly threaded nuts L
fixed or formed in the tops of housings G G. Saddles are interposed between
the lower ends of said screws and the trunnions of the said roll. The trunnions
of the top roll have bearing in boxes that rest upon vertically movable frames
or structures engaged and held in the desired adjustment by the pistons of

page_text: hydraulic cylinders and thereby supporting the roll at the desired elevation
controlled by the screws L.
The mechanism employed for rotating screws L is shown to be as follows:-
Upon the upper ends or portions of screws L (see Figs. I and III) are operatively
mounted corresponding worm wheels L' that mesh with corresponding worms M
formed upon a suitably supported and suitably driven horizontally arranged
shaft M. The operative connection between each wheel L' and the screw is
formed by the upper angular portion of the screw extending easily through a
correspondingly angular axial bore formed in the wheel, so as to accomodate an
endwise movement of the screws L independently of the wheel, without interrupt-
ing operative connection between the wheel and the screw.
The two rolls of each pair of rolls 1, 1 and 2, 21, of roll system A, are, ef
course, arranged in the same vertical plane.
The upper roll of each of the said pairs of rolls is adjustable vertically and
has its trunnions resting in boxes A+ movable up and down in upright
housings A A that are arranged at opposite sides, respectively, of the works
path. Boxes A rest upon and are consequently supported from vertically movable
frames or structures A engaged and held at the desired elevation by the pistons A
of hydraulic cylinders A8 and thereby supporting the roll at the desired elevation
controlled by suitably operated screws. Sadilles or blocks A rest upon the
trunnions of the roll above half boxes A, and the said screws engage correspond-
ingly threaded nuts fixed or formed in the tops of the housings and have their
lower extremities engaging the upper surfaces of saddles A.
The lower roll 2 of the pair of rolls 2 and 21, is suitably supported from the
iwo housings of the said pair of rolls.
The lower roll 1, of the pair of rolls 1, 1', is adjustable vertically and has its
trunnions resting in boxes A10 that are movable up and down in the upright
housings of the said rolls, and each of the said boxes rest upon, and is con-
sequently supported from, a vertical or upright screw 40 (see Figs. II and V)
that extends through and engages a stationary nut A
It will be observed, therefore, that the upper roll of the pair of rolls 2 and 21
and both rolls of the pair of rolls 1 and 1 are shiftable vertically for the purpose
hereinafter made apparent.
The screws 20, that are instrumental in vertically adjusting the upper roll of
the pair of rolls 1 and 1', are, when they are simultaneously rotated or turned,
operated uniformly, and the screw turning mechanism for the said screws com-
prises, preferably, two corresponding worm wheels 21, 21 operatively mounted
the different screws, respectively, above the housings, and meshing with
corresponding worms 22 that are formed upon a horizontally arranged shaft 23
suitably supported above and from the housings.
on
The screws 30, that are instrumental in vertically adjusting the upper roll of
the pair of rolls 2 and 24, are when they are simultaneously rotated or turned,
operated uniformly, and the screw turning mechanism for the said screws com-
prises, preferably, two corresponding worm wheels 31, 31, operatively mounted on
the different screws respectively, above the housings, and meshing with corre-
sponding worms 32 that are formed upon a horizontally arranged shaft 33 suitably
supported above and from the housings.
The screws 40 that are instrumental in vertically adjusting the lower roll of
the pair of rolls and 11 are when they are simultaneously rotated or turned,
operated uniformly and the screw turning mechanism for the said screws com-
prises, preferably, two corresponding worm wheels 41, 41, operatively mounted
on the different screws, respectively, and meshing with corresponding worms 42
formed upon a horizontally arranged shaft 43 that is supported in any approved
manner.
The operative connection between screws 20, 30 and 40 and the connected
worm wheels is exactly like the operative connection between screws L and
worm wheels L' so that each of the said screws 20, 30 and 40 is shiftable end-

page_text: wise independently of the connected worm wheel without interrupting operative
connection between the wheel and the screw.
The shaft 43 is operatively provided (see Figs. I and II) with a bevel gear 44
that meshes with a bevel gear 45 operatively mounted upon a suitably supported
shaft 46 that is arranged horizontally and at right angles to the shaft 43.
Shaft 46 is operatively provided with another bevel gear 47 that meshes with a
bevel gear 48 operatively mounted upon the lower end of a vertical shaft 49
that is arranged at one end of the pair of rolls 2 and 21 and is operatively pro-
vided, at its upper end, with a bevel gear 50 that meshes with a bevel gear 51
operatively mounted upon the worm shaft 33 that is instrumental as already
indicated, in the operation of the screws employed for shifting the roll 2. The
screws 20, 30 and 40 have the same pitch, and the gears of the operative con-
nection between the worm shafts 43 and 33, correspond diametrically and the
worms and the worm wheels of the mechanism for driving the screws 30 corre-
spond, respectively, with the worms and worm wheels of the mechanism employed
in the rotation of the screws 40, and consequently all of the screws are capable
of being simultaneously shifted at the same speed, so that the rolls 1 and 2 are
shiftable simultaneously and at the same speed, and the arrangement of the
screws and the parts of the mechanism employed in transmitting motion to the
screws, is such that the rolls 1 and 2 are when moved simultaneously by
the screws, shifted in opposite directions, respectively.
A clutch 52, (See Fig. II), of any improved construction, is interposed in the
line of the shaft 49, and is adapted to interrupt and establish continuity in
the said shaft, so that the rolls 1 and 2 can be shifted not only together but
independently of each other.
The worm shaft 33 (See Fig. I) is operatively provided with a bevel gear 29
that is in mesh with a bevel gear 28 operatively mounted upon a shaft 27 suitably
supported at the top of the roll system A and arranged horizontally and at
right angles to the worm shafts 33 and 23. The said shaft 27 is operatively
provided, also with a bevel gear 25 that meshes with a bevel gear 24 operatively
mounted upon the worm shaft 23. All of the gears of the operative connection
between the two worm shafts 33 and 23 correspond diametrically, and the worins
and worm wheels that are instrumental in shifting the roll correspond with
the worms and worm wheels, respectively, of the mechanism employed in shifting
the roll 2 so that the said rolls 1 and 2 are capable of being shifted simultaneously
and at an equal speed.
A clutch 26 capable of establishing and interrupting continuity in the shaft 27
is interposed in the line of the said shaft, and consequently the roll 11 cannot
only be shifted simultaneously with, but also independently of the roll 2.
The bevel gear 29 of the worm shaft 33 meshes, also, with a diametrically
corresponding bevel gear 35 that is operatively mounted upon the suitably
supported shaft 36 extending from over the roll system A to and over the roll
system B into suitable proximity to the worm shaft M of the last mentioned
roll system and operatively provided with another bevel gear 7 that meshes with
a bevel gear 38 which, in the case illustrated, has twice the diametrical size of
gear 37 and is operatively mounted upon the worm shaft M
It is obvious therefore, that the shaft 36 and connected mechanism upon the
transmission of motion to the said mechanism, by the latters operative con-
nection with the worm shaft M, are actuated twice as rapidly as the said worm
shaft, and one or more, or all, of the shiftable rolls 1, 11, and 2 are capable of
being shifted simultaneously with and twice as rapidly as the upper web reducing
roll, if the worm wheels and pitch of the worms of the mechanism instrumental
in shifting the said web reducing roll correspond, as they do in the case illus-
trated with the worm wheels, and pitch of the worms, respectively of the roll
system A.
A suitably operated clutch 39, of any approved type, for establishing and
interrupting continuity in the shaft 36, is interposed in the line of the said

page_text: shaft, and consequently the shiftable rolls of the roll system A can be shifted
simultaneously with, or independently of, the shifting of the top roll B' of the
roll system B.
The worm shaft.M is intergeared, at any convenient point as at m² with the
shaft m of an electric motor m.
The worm shaft 3 is intergeared, at any convenient place, at at n², with the
shaft of an electric motor #.
By the construction herein before described, it is obvious that any one of the
shiftable rolls can be shifted simultaneously with, or independently of, any of
the other shiftable rolls.
Those portions of the resisting or bearing affording rolls and 21 that are
adjacent to the roll proper, of the said. rolls, are sufficiently smaller diametrically
than the flange edge rolling rolls 1 and 2, to avoid contact or interference with
the work.
The operation of the mill illustrated is as follows:-The rolls; of the roll
system B, are set as required to readily receive the blank or section that is to
be rolled and that is transferred to the said roll system directly from a bloom-
ing mill or heating furnace (not shown) and enters the said roll system after
passing through the roll system A. The latter's shiftable rolls are at this time
so placed that the centres of the top rolls 1 and 2 of the roll system A, are as
much higher than the centre of the top web reducing roll 11 of roll system B,
as the web of the blank or section, that is to be rolled by the mill, is thicker
before entering the roll system B than it is after its first pass through the said
roll system B. Hence the piece under manipulation goes through the roll
system A upon its first pass without being effected by the rolls of the said roll
system A.
The mill is designed, in the case illustrated, to reduce the web, in its roll
system Bexactly as much in the second pass, fourth pass, sixth pass, eighth
pass and tenth pass, (if so many passes are needed) as the web is reduced in the
first. third, fifth, seventh, ninth and eleventh passes. After the section or blank
has made its first pass through roll system B upon the sections passage to the latter
from roll system A, the electric motor m is rendered operative and the shiftable
web reducing roll 13 and the rolls 1) D employed in working upon the outer
sides of the flanges are shifted inwardly far enough for the next or second.pass.
Clutches 39 and 26 are rendered operative simultaneously with the said motor so
that the rolls 1 and 2 of roll system A. are shifted simultaneously with the
shifting of the roll B' of roll system B and into position required for the second
pass of the work. While motor m and clutches 39 and 26 are operative, motor n
and clutch 52 are kept inoperative. As already indicated, the shiftable rolls of
roll system A are shifted twice as rapidly as the shifting of the roll B¹ of roll
system B and consequently, the shiftable rolls 1 and 2 during their adjustment
simultaneously with the roll B₁ are shifted as much. by one operation of their
shifting mechanism, as the said roll B is shifted by two operations of its shifting
mechanism, and therefore if the centres of rolls 2 and 1 are as much higher
then the centre of roll 13 as one half of the distance that the said rolls 1 and 2
are shifted during one operation of their shifting mechanism, as is the fact in
the case illustrated, it will be observed that upon the first operation of the shift-
ing mechanism of the said rolls 1 and 2 preparatory to the second pass of the
work, the centres of the said rolls 1 and 2 and the center of the said shiftable
web reducing roll B will be on the same level. When the roll B has been
lowered as required for the second pass and when the rolls 1 and 2 have been
lowered so as to bring their centres as low as the centre of the roll B', motor m
and clutches 39 and 26 are rendered inoperative. Electric connections and
appliances, whereby motor m and clutches 39 and 26 can be simultaneously
operated, are so well known that illustration thereof, in this application is not
considered necessary. When the shiftable rolls of roll system B have been set
to reduce the thickness of the web and flanges to the degree required for the

page_text: second pass, and when motor m and clutches 39 and 26 have been rendered
inoperative, the motor and the clutch 52 are rendered operative so that roll 1 is
shifted toward the opposing bearing-affording roll 11 and simultaneously roll 2
is again shifted toward the opposing bearing-affording roll 24, and both rolls and 2
are by the mechanism illustrated, shifted at the same speed. Rolls 1 and 2 are
now ready for the second pass, and motor and clutch 52 are again rendered
inoperative.
The distance that the roll 2 is lowered determines the amount that the width
of the flanges of the work or section is reduced, and this amount will equal the
distance that the roll 1 is raised plus the distance that the roll is lowered.
Now, the section or piece under manipulation, is passed through roll systems B
and A. The thickness of the web is reduced to the amount of space between
rolls Band B. The thickness of the flanges is reduced to the amount of space
between the side rolls D D and the ends of rolls Band B. The width of
flanges above the web is determined by the distance between roll 2 and 21. The
width of flanges below the web is determined by the distance between rolls ¹
and 1. The upper extremity of roll 21 and the upper extremity of the roll B
are on the same level. The lower extremity of roll 11 is on the same level with
the lower extremity of roll B' whenever roll system A is working on the edges
of the flanges. As already indicated, the said roll system A operates, only, in
the case illustrated, on the second, fourth, sixth, eighth and tenth passes, if
so many passes are needed, whereas roll system B operates upon every pass.
Before the section, that is being operated on, is passed through the roll system B
the third time, motor m is again rendered operative, but on this, as on the fifth,
seventh, ninth and eleventh passes, the clutches 39 and 26 are inoperative, and
hence no work is done by roll system A during the said passes. The section or
piece is then passed through the third time, and in this pass is operated upon by
roll system B only. Before making the fourth pass clutches 39 and 26 are
again rendered operative so that preparatory to the fourth pass the roll B is
lowered as much as it was lowered before the third pass and rolls and 2 are
lowered a distance equal to the descent of the roll B during both third and
fourth passes. Then motor m and clutches 39 and 26 are again rendered
inoperative and motor n and clutches 52 are rendered operative and roll 2 and
roll 1 are shifted simultaneously and correspondingly toward the opposite bear-
ing affording roll. Next, motor n and clutch 52 are again rendered inoperative,
and the section or piece is passed through the mill for the fourth time and is
reduced, in thickness of web and flanges by roll system B, and in width of
flanges by roll system A, and this operation is repeated on the sixth, eighth,
and tenth passes.
It must be obvious that by the mill illustrated flanges may be reduced to any
width at will by the action of motor n which, lowering the top roll 2 and at
the same time raising bottom roll 1, narrows the flanges above the web by and
between rolls 2 and 21 and narrows the flanges below the web by and between
rolls 1 and 11.
It is evident, also, as already indicated, that, before the second, fourth, sixth,
eighth and tenth passes,--the passes during which work is done upon the edges
of the flanges, roll 11 is level with roll B', that roll 2 is level with roll B², and
that roll 2 is always the same distance from roll 21 that roll 1 is from roll 11.
Now, while a very desirable arrangement, and combination of parts, is
described and shown in this application, it should be understood that, and with-
out departing from the spirit and scope of the invention, the operative con-
nection shown between the two roll systems, and comprising gears 37 and 38
might be omitted, and the roll shifting screws of roll system A might be worked
independently of the roll shifting screws of roll system B, and
independently of each other, and, instead of, reducing exactly as much in every
other pass, the reduction might be at the will of the operator who would decide
how much the reduction should be in any pass. The primary object of the

page_text: invention, as already indicated, is to avoid the necessity of changing roll collars,
or rolls, in the flange edge rolling roll system, for making different widths of
flanges, and to avoid the necessity of overturning the work. Of course the coupling
together of the two roll systems in a manner substantially as indicated in this
application, is a matter of convenience, but not of primary importance, although
at times very desirable.
Bottom guides (not shown) for preventing downward displacement of the work
during the mill's operation, and side guides (not shown) for preventing lateral
displacement of the work, should be provided, but such guides form no part of the
present invention and are, therefore not illustrated in this application..
The top guide T for preventing upward displacement of the work as the
latter passes from roll system B to rolls 2 and 21 of roll system A, is provided,
and is shiftable simultaneously and in unison with the roll B'.
A top guide 80 for preventing upward displacement of the work as the latter
passes from rolls
and 2 to rolls 11 and 1 is provided, and is shiftable simul-
taneously and in unison with the roll 2.
The object of a top guide, in the places indicated, is necessary or desirable
for the successful operation of a mill of the character indicated, and the guide
should be shifted simultaneously with the respective top roll and to the same
extent and in the same direction as the roll.
Top guide T is therefore clevated and lowered simultaneously and in harmony
with the elevation and lowering of the roll 13; and the arrangement of the guide.
relative to the roll, is such that the lower surface of the guide is approximately
flush with the roll's lower extremity. The guide T is arranged, furthermore,
centrally between the two housings G G and above the path of the web of the
work, and is supported, in any approved manner, from a vertically movable
slide. that extends between the two housings and engages slideways 66 formed
in and extending up and down the housings. The slide in the case illustrated,
consists of two parallel bars 60 and 61 that engage the slideways, and blocks or
pieces 62 interposed between and suitably secured to the end portions of the
bars 60 and 61, and forming a space 63 between the said hars for accommodating
the location of collars and nuts 64 and 65, respectively, that are mounted upon
the lower ends of the vertical screws 70 that are turnably attached to the upper
Abar 60. Two screws 70 are provided at opposite end portions, respectively, of
the slide. Each screw has an annular shoulder 71 resting upon the upper side
of the bar 60 and is reduced diametrically below the said shoulder,
and extends downwardly loosely through the said bar, and a nut 65 is
mounted upon the lower end of the screw below the said bar and a collar or
washer 64 is interposed between the nut and the bar. Each screw 70 extends
upwardly through and engages a nut 67 formed upon or rigid with the adjacent
housing, that is, two nuts 67 and 67 that are fixed to the different housings,
respectively, and are engaged by the different screws 70 and 70, respectively.
The screws extend a suitable distance above the nuts, and each screw above the
engaging nut, is operatively provided with a suitably supported worm wheel 72
that meshes with a worm 73 formed upon the shaft 74 that is arranged horizontally
and extends between and through the housings and has bearing in boxes 68
secured to or formed upon the outer sides of the housings. The operative con-
nection between each screw 70 and the engaging worm wheel is such that the
screw can move endwise independently of the worm wheel, and, in the case
illustrated the upper portions of the screws are angular and extend easily through
correspondingly angular axial bores in the said wheels. A sprocket wheel 75
is operatively mounted upon the shaft 74 between the two wormis 73 and 78, and
is operatively connected, by a chain 76, with a sprocket wheel 77 that is operatively
mounted upon the worm shaft M. The arrangement of parts is such that, by
the operative connection between the guide T and the worm shaft M,
hereinbefore described, the guide is lowered or
elevated according as
the roll ¹ is lowered or elevated by power transmitted from the
shaft M, and the guide and the roll are simultaneously shifted. It is obvious

page_text: that if as in the case illustrated, the sprocket wheels 75 and 77 correspond in
diameter, and the pitch of the screws 70, bears the same relation to the number
of teeth on the worm wheels 72 that the pitch of the screws L bears relative to
the number of teeth, on the worm wheels L', the guide T and roll B are equally
shifted during the operation of the shifting mechanism.
A counter balance for the guides, portion that extends between the slide T³
and the roll B is provided, and consists of a weight or poise To that is con-
nected with the said portion of the slide by a lever and links T and T¹ respectively
which lever is fulcrumed to the upper bar 60 of the slide and attached by the
said links to the counter balanced portion of the guide.
The manner of securing the guide T to the slide T3 comprises the provision, at
any suitable points longitudinally of bar 61 of the slide, of a pair of lugs 78
and 78 arranged at opposite sides, respectively, of the said bar and engaged, on
top, by a plate 19 that extends across and engages the upper side of the bar and
is bolted or otherwise secured to the said lugs.
The guide 80 and its shifting mechanism is substantially the same as the
guide and the latters shifting mechanism, and suffice it to state, therefore
that the shifting mechanism for the said guide 80 comprises two upright
screws 90 and 90 (see Figs. I and II) turnably connected to the guide and
engaging stationary nuts 87 operatively provided with and movable endwise
independently of worm wheels 92 that mesh with worms 93 formed upon a
suitably supported shaft 94 that is operatively connected, at 96 with the worm
shaft 33, and the arrangement of parts is such that the guide 80 and the roll 2
are shiftable simultaneously and in the same extent and in a corresponding
direction.
The guide 80 has, however, the arrangement and width required to cause it
to extend over the flanges above the web, and hence is arranged at an elevation
above the guide T as shown in dotted lines Fig. II.
