I, RICHARD MORLEY HARISON, of 228 West Regent Street, in the County of
the City of Glasgow, North Britain, Engineer, do hereby declare the nature of
this invention to be as follows, that is to say :-
My said invention has for its object to improve the construction of railway
chairs.
The improved chairs are made out of plates or strips of steel or iron or other
suitable metal, such plates or strips being either plain or of special section, and of
uniform or varying thickness, and being divided transversely to form the several
chairs. The chair jaws are formed by punching or cutting tongue-like parts in
each plate the inner or root parts remaining undivided from the plate; and in
subsequently bending up such tongue-like parts into forms suitable for the chair
jaws, the tongue on one side being made to fit the web of the rail, and if desired
extending up to bear against the head of the rail, and the tongue on the other side
being shaped to receive the wooden or other key between it and the rail. The
jaws may be shaped to suit various sections of rail.
In one modification corrugations are formed in the plate either in the rolling
process or by subsequently stamping or pressing, such corrugations being parallel
to and at each side of the part of the chair on which the rail rests. In another
modification the middle part of a chair plate is made thicker or with a shallow rib,
either parallel to the rail seat or transverse thereto. In both cases the plate or
strip is rolled with the thicker part longitudinal, and is cut transversely to form
separate chairs, but in one case the jaws are formed on each side of the thickened
part and in the other case they are formed out of the thickened part.
In another modification the jaws are formed without cutting through the plate
but by doubling up parts of the plate, into the proper shape, the shaping being
effected by a series of separate successive stamping or pressing operations.
The chair plates are formed with holes for spikes or fastenings; and each may
have combined with it an under plate if considered desirable for giving increased
strength.

I, RICHARD MORLEY HARISON, of 228 West Regent Street, in the County
of the City of Glasgow, North Britain, Engineer, 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 in writing :-
My said invention has for its object to improve the construction of railway
chairs.

page_text: The improved chairs are inade out of plates or strips of steel, or iron or other
suitable metal, such plates or strips being either plain or of special section, and of
uniform or varying thickness, and being divided transversely to form the several
chairs. The chair jaws are formed by punching or cutting tongue-like parts in
each plate the inner or root parts remaining undivided from the plate, and in
subsequently.bending up such tongue-like parts into forms suitable for the chair
jaws, the tongue on one side being made to fit the web of the rail, and if desired
extending up to bear against the head of the rail, and the tongue on the other side
being shaped to receive the wooden or other key between it and the rail. The
jaws may be shaped to suit various sections of rail.
In one modification corrugations are formed in the plate either in the rolling
process or by subsequently stamping or pressing, such corrugations being parallel
to and at each side of the part of the chair on which the rail rests. In another
modification the middle part of a chair plate is made thicker or with a shallow rib,
either parallel to the rail seat or transverse thereto. In both cases the plate or
strip is rolled with the thicker part longitudinal, and is cut transversely to form
separate chairs, but in one case the jaws are formed on each side of the thickened
part and in the other case they are formed out of the thickened part.
In another modification the jaws are formed without cutting through the plate,
but by doubling up parts of the plate into the proper shape, the shaping being
effected by a series of separate successive stamping or pressing operations.
The chair plates are formed with holes for spikes or fastenings; and each may
have combined with it an under plate if considered desirable for giving increased
strength.
And in order that my said invention, and the manner of performing or carrying
the same into practice may be properly understood I have hereunto appended an
explanatory sheet of drawings in which the same reference letters are used to
indicate equivalent parts in all the figures where shown.
Figure 1 is an end elevation of an improved metallic chair with wooden block
and rail; Figure 2 shows section of same.
Figures 3 and 4 are side elevations looking at opposite faces.
Figure 5 shews the chair in plan with the rail and wooden block removed.
Figure 6 is an end elevation of a similar but uncorrugated chair, and Figure 7 is
the plan of same.
Figure 8 is also an end elevation of a chair varying in detail from the former,
and Figure 9 is the plan of same and Figure 9 is a cross section of the chair bar
as originally rolled.
Figures 10 and 11 are similar views shewing the application of this chair for
Vignole or tee: rails.
Figure 12 shews a plan and edge view of a plate which may be used as a bearing
sole underneath the chair.
Figures 13 and 14 shew an elevation and plan respectively of chair with a longi-
tudinal central rib, and Figure 15 is an end section taken on the line X-X of
Figure 14, the chair being formed by being punched and then folded into
position.
Figures 16. and 17. are an elevation and plan view respectively shewing the
chair as crimpled or folded up into position to receive the rail and key. While
Figures 18, 19, and 20, are views corresponding to Figures 13 to 15 but formed
by saw or like cutting, and bending or folding up the ends of chair into position for
receiving the rail and key, instead of being punched and folded as in the aforesaid
figures.
Referring to these drawings:-The chair is manufactured from an iron steel or
other, suitable metal plate or bar p. The tongues or lips.a and 5, holding the. rail
in place by means of the ordinary wooden block or key wedge e, are punched or
forged out of the bar p, leaving openings o and of in the body of the plate, as shewn
in the plan, Figure 5. The folds or corrugations c and d shewn in Figures, 1, 2,
& 5 are either forged in the usual process of rolling of original bar or plate, or are

page_text: pressed to suitable curve and height after bar and plate is rolled, as shown; in
order to give suitable seat to foot of rail and to assist in taking the thrust which
may be placed on the rail from flange of wheel coming on the rail. The chair is
fastened to wooden sleepers, by spikes or bolts or other means as usually employed.
In the case of the chair being used in connection with metallic sleepers, the con-
nection would be made by means of the usual bolts, or rivets. Figure 5 shows
three holes for spikes connecting same to sleeper, but the number and position of
these holes may be varied. Figures 6 and 7 shew a chair in which the lips or
tongues a. b. have been bent in towards the rail to retain same, in which case the
plate or bar is made thick enough to obtain the necessary bending resistance at the
points u and c. Figures 8 and 9 shew chair with lips or flanges a. b, bent towards
the rail with thickening at the points m and n. in order to produce sufficient.
strength instead of producing same by means of an original heavier flat bar. In
this latter case the length of the chair from to w' would be the width of the
originally-rolled bar. The thickened portions m and a are produced by rolling
ribs longitudinally in the body of the bars or plates. In case that it is desired the
longitudinal rib, or ribs, is rolled in the direction shewn in Figures 13 to 15,
thereby giving increased thickness to the curved lips a. b. as shewn. In this latter
case the width of original har or plate is y. y'. These ribs may be either on top or
on bottom, or both on the top and bottom of the plate or bar, out of which the
chair is subsequently manufactured. The thickened portion may be produced by
means of longitudinal ribs, such as described, which may be either continuous in
the body of the bar or joggled, so as to produce this thickness at the points m
and n only. If necessary this chair can be reinforced by means of a plate between
chair and sleeper thereby producing greater stiffness over bearing surface; the
said plate being punched sanie as chair as shewn in Figure 12.
Having now particularly described and ascertained the nature of my said inven-
tion, and in what manner the same is to be performed I declare that what I
claim is:
First. The improved construction in arrangement and combination of the parts
of a metallic rail chair, rolled, pressed, or forged out of a metallic plate, or bar,
having two tongues or curved lips pressed out of same and curved inwards and
upwards towards the rail so as to hold same with its ordinary wooden key or block
its bending resistance being obtained by increasing the thickness of the lips, or by
suitable folds or corrugations, or by making the original plate thick enough to
meet the required strain substantially as described in reference to and by way of
application shown in the accompanying drawings.
Second. The improved construction of a rail chair with rolled or forged corru-
gations, in the entire width of bar in the direction parallel with the rail, and then
pressed into required form to hold the rail and its wedge block, substantially as
herein described in reference to and shown in the accompanying drawings.
Third. Rail chairs formed substantially as described in reference to and shown
in the accompanying drawings.
