Improvements in Apparatus for Rolling Metallic Beams, Girders, or
Columns.
I, REGINALD HADDAN, of the Firm of Herbert Haddan & Co., of
18, Buckingham Street, Strand, in the County of London, Patent Agent, do
hereby declaro the nature of this invention a communication to me from abroad
by Heary Grey, of Duluth, in the County of St. Louis, United States of
America, Mechanical Engineer and Manufacturor, 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 apparatus for rolling metallic beams,
girders, or columns, and comprises primarily, a pair of suitably rotated parallel rolls
arranged horizontally, one above the other, and in the same vertical plane, and
adapted to roll the web and inner sides of the heads or flanges of the column,
beam, or girder, and a pair of upright rolls arranged centrally between the axes of
the two horizontally arranged rolls and at opposite ends, respectively of the
horizontally rolls, and adapted to roll the onter sides of the flanges or heads of
the column, beam, or girder, in combination with simple and reliable means for
driving the upright rolls in unison with the horizontal rolls and compelling the
upright rolls to participate in the feeding of the work between the rolls.
The invention involves, also, an apparatus of the character indicated that com-
prises, in addition to the system of rolls for rolling the web and opposite sides of
the heads or flanges of the work, another system of rolls arranged to roll the
edges of the work's flanges or beads, and arranged, furthermore sufficiently near
to the first mentioned system of rolls to cause the blank or work to be operated
upon by either one of said roll systems, before it has left the other roll
system, and suitable driving machinery for operating both of said roll systems
in unison.
The invention consists also, in certain novel and meritorious features of
construction, and combinations of parts, hereinafter described and pointed out
in the claims.
In the accompanying drawings

Fig. 8 is a top plan in horizontal section on line 8-8 Fig. 7.
This improved apparatus for rolling columns, beams or girders, as illustrated in
Fig. 1, comprises two systems of rolls one rll system A for rolling the edges of
the heads or flanges of the column, beam, or girder, and the other roll system B
for rolling opposite sides of the flanges or heads and the web of the girder, beam,
or column. The two roll systems A and B are located side by side, and in suh
proximity to each other that the 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, preferably at the same
speed, and the work is fed in opposite directione, alternately, between and through
the two roll systems us many times as required to complete the rolling of
the work.
The rolls of the two systems of rolls are, of course rotated in the direction
required to feed the work, and the direction of their rotation is of course
reversed preparatory to feeding the work in the opposite direction after the
latter has been fed in either direction through the systems of rolls.
The roll system A employed for rolling the edges of the beads or flanges of
the beam, girder, or column, comprises two pairs of parallel horizontal rolls. See
Figs. 1, 2, and 3.
A designates the rolls of one of said pairs of rolls, and A' represents the
rolls of the other pair of rolls. The two pairs of corresponding rolls are arranged
a suitable distance apart, and the rolls of each pair of rolls are arranged, one
below the other, and in the same vertical plane. The upper rolls of the two
pairs of rolls are operatively mounted upon, or connected with, a horizontal
shaft A that is adjustable vertically and has hearing in half boxes A' movable
up and down within the two upright housings A, and resting upon or supported
from any suitable number of upright bars A operatively connected, at their
lower ends, with vertically tilting weighted levers A' whose weights A³ somewhat
more thau counterbalance the weight of shaft A and the rolls upon said shaft,
and act in the direction required to elevate said rolls. Saddles or blocks A' rest
up n shaft A above half boxes A' and suitably operated screws A10 engage corre-
spondingly threaded holes in the tops of the housings and engage the upper
surfaces of saddles A and limit the upward movement of shaft A and the rolls
upon said shaft.
Means or mechanism of the character indicated for adjusting
a horizontal roll vertically and retaining it at the desired elevation, are well under-
stood by those skilled in the art and do not require further description in this
sjecification. Suffice it to state that screws A should he uniformly operated,
and that the upper rolls are elevated or lowered, according as said screws are
turned in the one direction or the other. The two upper rolls are confined upon
shaft A between the different housings A' A respectively, and a collar A" formed
upon said shaft centrally between the two housings. The two lower rolls are
operatively mounted upon or connected with a horizontal shaft A" suitably supported
from housings A', and said lower rolls are confined upon said shaft A" between the
different housings, respectively, and an annular collar As formed upon the shaft
centrally between the housings.
Although the drawings illustrate rolls adapted for the production of I-beams or
girders, it should be understood that the principle of the invention is not merely
applicable to the rolling of this particular form of beam or work.
The suitably heated blauk or I-beam or work C, in the caso illustrated is, of
course fed longitudinally and with its flanges or heads arranged edgewise between
the upper and lower rolls of the pairs of rolls AA, and the two flanges or heads

page_text: of the blank or work are operated upon by the different pairs of rolls, respectively,
and the two rolls of each pair of rolls operate upon opposite edges respectively,
of the respective flange. Collars A" and A" are larger diametrically than the
rolls, but are narrower than the web of the work constituting beam and are not
sufficiently large diametrically to make contact with, or operate upon the web.
In other words, collars A and A" merely serve as lateral guides for the work
during the rolling operation, and effectually prevent displacement of the work
Interally during the said operation, and the upper rolls can he re-adjusted vertically
after each pass of the work to accommodate the widening of the heads or flanges
of the work during the preceding pass.
Shaft A (see Fig. 2) is operatively connected by means of suitable couplings
or connections A" with a suitably supported horizontally arranged shaft a, and
shaft A is operatively connected, by means of suitable couplings or connections A",
with a horizontal shaft a' arranged above and parallel with shift a. Two spur
gears a³, a operatively mounted upon shafts a and a 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 manner, with a suitably
supported and suitably actuated driving shaft a. By the construction thus far
described it will be observed that the rolls of each pair of rolls A' and A' are
driven in opposite directions respectively, as required.
Another pinion a (see Fig. 1) is operatively mounted upon driving shaft a' and
meshes with a spur gear a' operatively mounted upon a horizontal shaft a suitably
supported at one side of and a suitable distance from shaft a and operatively
connected by means of suitable couplings or connections a with a spur gear alo
arranged in line with shaft a and between said shaft a aud the trunnion (see
Fig. 1) of the lower roll B of the pair of parallel corresponding horizontal
rolls B B arranged one above the other in the same vertical plane, and parallel
with rolls A' A, and employed in rolling the web and the inner side of the heads
or flanges of the beam that is being rolled, and any suitable couplings or
connections establish operative connection between said trunnion b' and gear alo.
A spur gear a is arranged above and parallel and meshes with spur gear a".
Gear a is operatively connected by suitable couplings or connections 6, with oue
of the trunnions & of the upper roll B' of the aforesaid pair of horizontal rolls.
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 such
that the rolling or operating surfaces of said rolls shall be driven at the sanic speedl
or nearly so.
The two rolls B', B' are driven in opposite directions, respectively, and the
upper roll B' and the lower roll B2 are driven in the same direction as the upper
rolls and lower rolls, respectively, of the two pairs of rolls A', A'.aud hence, the
work can be fed from rolls.A', A', to rolls, B, B', or vice versa, according as the
driving shaft is actuated in the one direction or the other, and the two systems of
rolls are 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. Of course, rolls B, B aro arranged in line with
collars A" and A13 respectively, of shafts A and A", but said rolls B', B³, ara
sufficiently wider, and diametrically larger, than said collars to enable them to
properly operate upon the web and the inner sides of the flanges of the beam that
is being rolled. The upper roll B' is of course, adapted to operate upon the upper
side of the web and adjacent inner surfaces of the heads or flanges of the beam,
and the lower roll B is adapted to operate upon the lower side of said web and
the adjacent inner surfaces of said heads or flanges.
Any suitable number of suitably supported horizontally arranged rolls C,
(shown in Fig. 1 only) are preferably arranged between the two systems of rolls
in position to afford a bearing for the beam or work in the passage of the latter
from the one to the other system of rolls.
Two suitably supported side rolls D and D', shown arranged vertically, at

page_text: opposite ends, respectively, of the horizontal rolls B', B', and centrally between
the axes of said horizontal rolls. (see Figs. 4, 5, 7 and 8) are adapted to roll or
operate upon the outer sides of the oppositely located flanges or heads respectively
of the bean. It is obvious that, in order to accommodate repeated rollings of the
work and different sizes of work, the upper roll B' must be adjustable vertically,
and the two upright rolls D and D' must be adjustable apart.
Before referring to the mechanism employed for effecting the adjustment of said
adjustable rolls, it should be observed that, in order to render the rolling of a
flanged beam, column or girder practical, live surfaces should he present to all
sider of the work, and consequently the upright rolls for rolling the outer sides of
the flanges must be driven in unison with the horizontal rolls B B and the very
simple and durable operative connection devised between each of said upright
rolls and the adjacent trunnion of the upper horizontal roll B' comprises preferably,
a horizontal friction wheel or disc d (sec Figs. 4, 6, 7 and 8) operatively connected
with the respective upright roll in any approved manner and preferably by the
formation of interlocking lugs d and D upon said friction wheel and the roll,
respectively. The upright roll is bored centrally, as at D. (see Fig. 7) and the
Jugs D are formed upon the upper portion of the surroun ling wall of stid bore,
(see also Fig. 8). The friction wheel 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 wheel for the purpose hereinafter made more apparent.
Said friction wheel d, at its upper end, is provided with an external annular
bevelled or conical friction surface d' that is frictionally engaged by a corresponding
annular bevelled or conical friction wheel or disc B 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 wheels or
discs dd, respectively, so that the two upright sido rolls D D' 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. It is obvious that all of the live surfaces operating upon the
work should be driven at the same speed and hence the relative diameters of
wheels/d and the connected rolls D D' are so proportioned to the relative diameters
of discs B on rolls B 1 that the rolling or operating surfaces of all of said rolls
shall be driven at the same speed or nearly so. Friction discs B are preferably
removably mounted upon the supporting roll trunnions, to accommodate their use
with any size of rolls employed in rolling the wel of the blank or work. By
means of the vertical adjustability of discs d, frictional engagement is maintained
between soid friction members and the friction discs B', upon elevating or vertically
re-adjusting the upper horizontal roll B'.
The means acting to elevate each friction disc d and maintain frictional engage-
inent between said friction member and the engaging Iriction disc B, comprises,
preferably, n piston E provided, at or near its upper end with an external annular
fange E that engages the under side of and supports member d that is secured to
the piston, profera bly by a nut el (see Fig. 7) mounted at the upper side of said
member d upon an externally screw threaded upright lug e of the piston and
extending upwardly through the central portion of said member d. The piston
extends downwardly into the chamber formed in the vertical cylindrical lug or
cylinder F formed upon the upper side of a block F, and upon said cylinder the
upright roll, that is operatively connected with the aforesaid friction disc d, is
mounted. Block F', at the lower end of cylinder or bearing F, is provided with
a horizontal annular shoulder F, (see Fig. 7) and antifriction balls are inter
posed between said shoulder and the lower end of the roll, and reduce the friction
had between the opposing surfaces of euid roll and shoulder, during the operation
of the roll, to a minimum. A port or passage way f¹ for conducting water or
fluid under pressure to chamber F is formed, in any approved manner, within

page_text: block F and communicates with the aforesaid chamber. The fluid under pressure
within said chamber, acts to force the piston upwardly and thereby causes the
horizontal friction disc d to be held in frictional contact with the engaging friction
disc B³. 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. Block F¹ straddles, but does not rest upon the adjacent trunnion of
the lower horizontal roll B' as shown in Figs. 4, 6 and 7. Said roll B has its
trunnions suitably supported within the lower ends of the two upright housings GG
arranged at opposite ends respectively, of rolls B' B', and said block F¹ rests upon
horizontal shoulders g formed upon the opposing internal walls of the adjacent
housing, (see Fig. 6). Blucks F slide upon shoulders g during the adjustment of
the two upright rolls D and D' towards and from each other. Each housing G,
near its lower end, and at the top of the trunnions of the lower horizontal roll, is
provided with Intorally and outwardly projecting brackets G' having tongues G
engaged by the grooves h (see Figs. 4 and 5) formed iu a slide H. That is, two
horizontally movable slides HII are arranged at the outer sides of the different
housings respectively, and each roll bearing block is rigidly secured to the
adjacent slide H by any suitable number of bolts H' extending through the slide
into said block F1, as shown in Fig. 5, and hence, the upright roll borne by said
block is adjusted toward or from its companion roll according as slide H is
moved laterally of the supporting housing in the one direction or the other. Each
slide His provided preferably, with two screws H arranged parallel with the
slideways for said slide, and a suitable distance apart, and operatively connected
with the slide in any approved manner. Said screws engage a correspondingly
threaded out I confined or rendered stationary within recesses y formed in the
outer sides of the aforesaid housing brackets, as shown in Fig. 5. By this con-
struction it is obvious that each slide H and the members supported thereby are
adjusted toward or from the pair of horizontal rolle, according as the engaging
screws are turned in the one direction or the other.
Housings Gare preferably tied together and braced apart by any suitable number
of suitably applied borizontally arranged rods G³.
Each slide H is also provided with a thrust bearing for the upright roll that is
indirectly supported from said slide, and said thrust bearing cousists preferably, of
segmental plate J (see Figs. 5, 7, and 8, composed of a very hard metal or
material and supported on edge from the slide at that side of the roll that is
opposite to the point at which the roll operates upon the work.
Said thrust plate is furthermore, arranged concentrically of the axis of the roll,
and any suitable number of suitably supported upright antifriction rollers Jaro
preferably interposed between the thrust plate and the roll to reduce the friction
between the opposing surfaces of said plate and roll to a minimum. The port or
passage way formed within each block F is arranged in line and communicates
with a port or passage way that extends through the slide H with which said
block is operatively connected, and communicates, at its outer eud preferably, with
a flexible pipe or hose K (see Fig. 4) that connects with any suitable source (not
shown) for supplying the fluid under pressure and by virtue of its flexibility,
accommodates the adjustment of said slide.
To prevent overheating of the mutually engaging friction discs d and B' and
the connected rolls, each chamber f communicates with a port (see Fig. 7)
extending upwardly through the piston that extends into said chamber, and said
port, at its upper end terminates in a nozzle or nipple e arranged to discharge
upwardly above the adjacent friction discs d and against the adjacent trunnion of
the upper horizontal roll B', and the water or cooling agent spreads or circulates
to the engaging surfaces between said friction discs.
The upper horizontal roll B' is supported preferably, exclusively from the fluid
under pressure, and through the medium of pistons E, upon which said fluid acts,
and the friction discs interposed between said pistons and the trunnions of
said roll.

page_text: Two upright screws L L (see Figs. 4 and 6) engage correspondingly threaded
holes formed in the tops of housings GG and are arranged to form stops that limit
the upward movement or elevation of the upper horizontal roll B'. Saddles
are shown interposed between the lower ends of said screws and the trunnions of
said roll.
By the construction hereinbefore described, it is obvious that upon turning
screws L in the direction required to elevate them, the upper horizontal roll B' wifi
be elevated by the action of the fluid under pressure upon pistons E.
Having thus described suitable means for obtaining the adjustment of the
upright rolls D and D' towards and from each other, not only to accomodate
different sizes of work, but as required during the rolling of work of the charactor
indicated, and having also described suitable means for effecting a vertical
adjustment of the upper horizontal roll B' towards and from the lower horizontal
roll B' and indispensable in the process of doing work of the character indicated,
it should be stated that it is also desirable to have the screws employed in effecting
the vertical adjustment of said upper horizontal roll and the screws employed in
effecting the adjustment of the vertical or upright rolls D and D', operatively
connected with each other, and this is readily accomplished by means of the
following well known gearing and shafting: A bevel gear L' is operatively
connected with the upper end of each scrow L; a suitably actuated horizontally
arranged shaft M is suitably supported from said screws, and two bevel
pinions M M operatively mounted pou said shaft M, mesh with the corre
sponding sides of the different bevel gears L', respectively. A bevel gear h³ is
operatively mounted upon the outer end of each screw H' and meshes with a bevel
pinion O' that is operatively mounted upon a suitably supported upright shaft O.
A suitably supported bevel gear O' is operatively and slidably mounted upon the
upper end of each shaft O and meshes with a bevel pinion M that is operatively
and slidably mounted upon shaft M and provided with a vertically arranged
sleeve M* slidably mounted upon a vertical upright H' that is rigid with the slide H
.below.
Two pairs of horizontal guide bars (see Figs. 4, 5 and 6) are arranged at
opposite sides, respectively, of and centrally between the axes of rolls B', B', and
the bars of each pair of guide bars are arranged at opposite sides respectively, of
the path of the work. Said bars prevent lateral displacement of the work
during the feeding of the latter to and from the rolls. The members of each pair
of guide bars are adjustable apart and are secured in any approved mannor, by
menus of rods P, to the different slides H, H, respectively, and each of the guide
bars is seated near its inner end upon a shoulder F (see Fig. 7) formed upon the
block F that is secured to the slide instrumental in supporting said bar, and said
bluck is provided preferably with an upright lug or flange F bolted as at F', to
the guide bar. By this construction, each guide bar is well supported, at or
near each end, and is not liable to be bent laterally or buckled by the work.
