Improvements in Rolls for Shaping Connecting Plates for the Joints
of Railway Rails.
I, HUGH DONALD FITZPATRICK of 70 Wellington Street Glasgow in the County
of Lanark, Registered Patent Agent, do hereby declare the nature of this invention
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 certain improvements in rolls for shaping connecting
plates for railway joints, the object of which is to facilitate the operation of
manufacturing said connecting plates and to enable the same to be made with
great uniformity and exactness and thus better adapted to engage the bearings on
the railway track or rail.
The invention consists in the improved rolls having the arrangements and
constructions of parts substantially as will be hereinafter set forth and finally
embodied in the clauses of the claims.
Referring to the accompanying drawing in which like letters indicate corresponding
parts in each of the several figures,
Figure 1 is an elevation showing the relations of the rolls to one another, the
bearings for the rolls being merely indicated in outline, there being no particular
features of novelty therein.
Figures 2, 3, 4, 5, 6, 7 and 8 are enlarged detail sections of the rolls showing more
clearly the outlines of the several apertures or passages between said rolls through
which the bar of iron or steel is passed.
In said drawings, a, b, c, indicates three rolls having sets of peripheral grooves
and ridges a', a², b¹, b², c¹, c³, d¹, d², e', e², f'¹ ƒ², g¹, g², which co-operate in forming the
series of apertures or passages in which the bar is shaped longitudinally and given
the final form in which the said bar, when cut to proper lengths and otherwise
finished, is adapted to engage the bearings of the rails.
The first pass or opening, through which the square bars of iron from which the
connecting plates are made has been numbered 1 in the drawing and has been shown
more clearly in Figure 2. The said opening is formed by the low projecting male
ridge a entering a deep groove in the opposite roll. The said projecting ridge
having on the peripheral face thereof, the set of working faces a'. Said set consists
of the ridge a having the two inclined faces a, a, the first being nearly parallel
with the axis of the roll and the second having a greater inclination, and the ridge a',
having the long inclination a³, formed at an angle to the face or bearing aº, and
forming with said face, a, a shallow groove a".
"
The female part on the opposite roll is adapted to receive the male projection, a³,
and form the passage 1. The sides of the deep groove are inclined as at a
to a degree closely approaching a right angle to the axis of the roll, and at
the bottom is formed a low projection, a", having oppositely inclined working
faces, a, a, approaching the inclination of the working faces, a³, a³, in the
opposite rolls.
In passing the square iron or steel through the first aperture or passage, the same
is given an irregular oblong shape in cross section, with a longitudinal V-shaped
groove on one side and a corresponding ridge on the opposite side.
In passing the iron from the first passage 1, to the second passage 2, the ingot is
reversed in position, for convenience in rolling, but the outlines are similar to those
described in connection with passage 1, excepting that the depth of the passage is

page_text: more shallow and the bar is consequently reduced in thickness but increased in length
as will be understood..
In the set of this aperture, the projecting ridge 6 corresponds with the ridge a¹³,
and the working faces, 65, 66, 68, likewise correspond with a³, a', a³.
The
In the next passage of the bar, through aperture 3, the lines of the bar are
materially changed and the said bar is still further reduced in thickness.
roll is provided, in addition to the ridge c¹, with another ridge, c¹³; which is of a
rounded shape in peripheral outline and has the groove, e, between.
The projection, e corresponding to a¹ and is given increased projection, and
on the opposite co-operating roll bearings, c; the working faces, c, co, become
oppositely inclined and as a result the bar is given a more distinct corrigated shape
with distinct grooves on one side and a second groove on the other.
.
And so in apertures 5 and 6, the working faces change by gradual variation and
shape the bar so that when it is: prepared to pass through the final passage, 7, no
work is left but to bend the bottom Hange to a condition to engage the bottom of
the rails when the inner working faces of the vertical part of the connecting plate
engage the web of the rail.
The construction of the aperture 7 through which the bar passes is substantially
as shown in Figure 8, where the portion 17 of the passage 7 is substantially the same
in outline as the portion 16 of the passage 6.
The roll; b, at this final passage, is formed, at 93, to engage or nearly engage
the opposite roll. From this point the surface extends in a direction substantially
parallel with the axis, of the roll a distance equal to the desired thickness of the
bottom flange to be formed in the portion, 27, of the aperture or passage 7; the
surface then abruptly inclines outwardly at g', and then backwardly as at 9, in an
opposite direction and forms the narrow flange g. At the base of the flange, a
shallow annular recess 9, is provided from which the peripheral surface, has
another low but comparatively wide projection, 9', and on the opposite side of
the projection, from the recess, 6, is another recess g. The walls of the
recesses g, g, form the bearings on the inner side of the vertical portion of the
connecting plate, while the projection, y', forms the recess on the rear of said
vertical portion.
From the recess, y, the walls of the aperture extend a distance equal to the
desired thickness of the said vertical portion into or near to engagement with the
co-operating roll as at g³.
The set of working faces, 92, of the roll, c, give shape to the exterior faces of the
connecting plate and have the following constructions and relations.
At go a long, working face is formed extending substantially at right angles
to the working face which working face. terminates at a point distant from
the working face equal to the desired thickness of the plate portion, which
engages the top of the flange of the rail. From this point, the surfaces, form a
deep groove, in the roll c, the bearings being substantially parallel with
the working face, g, and the opposite working face, g, being substantially
parallel with the working face g, and terminating at or near the point, 31, of
the roil .

The series of projections a, b, c, d, f, g, vary from an obtuse angle to
the acute angle shown at Figure 8 and bring the portions 18, 27, of the passage
7.
so that the inner limits or walls of said passage correspond with the upper and
tinder bearings of the flange of the rail.
By means of the rolls constructed as described, we are enabled to roll out the
connecting plates so that great uniformity in the disposition of bearings, is, secured
which conduces to an increased smoothness and firmness at the joint.

The means for operating the rolls being old, it has been deemed unnecessary to
illustrate the same.
We do not wish to limit ourselves to, the number of rolls employed as it is evident
that the passages may be formed in other than the three. rolls without departing
from the spirit or scope of the invention.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what
we claim is:
1. In a machine for forming railway rail connecting plates, the combination of
the roll, having a narrow projecting flange, g, with oppositely inclined working
faces y, g, and at one side of said flange having the working surfaces, 98, 9³, and
comparatively low projection g7, the said working faces g, g', g, being adapted to
give form with the co-operating roll to the concavous vertical portion of the said
connecting plates, and the roll, e, having a working face substantially parallel
with the line of the working faces g, 98, and having a deep groove formed by the
oppositely inclined faces ", " lying substantially parallel with the faces g', 9, the
said working faces being formed to produce a connecting plate having a vertical
part to engage the web of the rail and bearings to engage the top and bottom of
the flange thereof, substantially as set forth.
2. In a machine for making connecting plates for railway rails, the combination
with the roll, b, having the working surfaces y¹, of the roll, c, having the
working surfaces g', the two sets of surfaces forming the pass, 7, of which the
portions 18, 27 form a sharply acute angle one with the other, and the portion, 17,
having the bearing recesses g and 98, forms an obtuse angle with the portion 18,
to secure a connecting plate having a bearing or bearings on the web of the rail
and on the top and bottom surface of the flanges of the rail substantially as
set forth.
3. In a machine for making connecting plates for railway rails, the combination
of rolls forming passes 1, 2, 3, 4, 5, 6, and 7, of which the first of said passes has
a coincident angular recess and projection, the second a similar recess and pro-
jection, the pass being of reduced depth, the third of still further reduced depth
and having another, an obtuse angle formed in the pass, the fourth, fifth and sixth
passes being also of reduced depth and the projections d, e, and 13, formed with
the coincident working faces pass portions approximating right angles and the
pass, 7, having the projection, formed much more acute than said pro-
jections de "the portions 18, 27, of said pass being adapted to form the upper
and lower bearings to engage the flange and the portion 17, to form the web
bearings, substantially as set forth.
4. In a machine for making railway rail connecting plates, the rolls having
a series of passes which gradually contract in depth, and the last pass of
the series having the portions 27, 18, form a sharply acute angle and the
portions 18, 17 an obtuse angle to give the desired shape or form to the vertical
web bearing and the top and bottom flange bearings substantially as set forth.
