Improvements in Railway Chairs.
A communication from THOMAS DAVIES, Brewer, and President of the Davies
Brewing and Malting Company, Limited, of the City of Toronto, in the County
of York, in the Province of Ontario, Canada.
CHARLES AUBREY DAY, of 321 High Holborn, in the County of London, Fellow
of the Institute of Patent Agents, do hereby declare the nature of this said invention
and in what manner the same is to be performed to be particularly described and
ascertained in and by the following statement :-
The object of this invention is to provide a chair for railroad iron, which will
effectually prevent the rail tilting spreading or being displaced on curves, and when
used in connection with a fish-plate, will act as an effective nut-lock; and it consists,
essentially of a chair composed of a bed plate having an upwardly-projecting flange
designed to fit against and brace the bottom side of the rail head; the junction
between the base-plate and the upwardly-projecting flange being formed to receive
and securely hold one side of the foot of the rail, and when used in connection with a
fish-plate the upwardly-projecting flange is shaped to fit between and lock the nuts
of the fish-plate bolts, substantially as hereinafter more particularly explained.
Figure 1) is a perspective view of my improved chair applied to a rail without a
fish-plate.
Figure 2) is a cross-section of same.
Figure 3) is a perspective view of my improved chair as it will appear in the act
of being applied to a rail-joint secured by a fish-plate.
Figure 4) is a similar view, but showing my chair in position to brace the rail and
act as a nut-lock.
Figure 5) is a view of the opposite side of the rail-joint shown in Fig. 4.
Figure 6) is a cross-section of Fig. 4.
Figure 7) is a cross-section of my improved chair applied to a double-headed rail.
In the drawing, A represents the head of the rail; B the web or stem connecting
the head A, to the base or foot C, of the rail, and D, is the base of my improved chair
designed to fit below the foot of the rail. E, is an upwardly-projecting flange
extending from the base D, to the bottom of the head A, forming a lateral brace for
be rail, which is further securely held to the chair B, by the side of the foot C, fitting
losely into the recess formed by the junction between the flange E, and base D, as
ndicated.
F, represents spikes driven into the tie or sleeper G through holes made in the
ase D and fitting into a notch made in the foot C, of the rail. H, represents other
bikes driven into the tic or sleeper G, through holes made in the flanged side of the
air.
By the adoption of my invention, fish-plates may be dispensed with, and at the
me time the rails will be very securely braced.
My improved chair is also applicable to the joints of rails secured together by fish-
ates, and as a rule it will be found that by the adoption of my improved chair, a
h-plate on one side of the rail only will be found sufficient.
When my improved chair is made to be used in connection with fish-plates, the
wardly-projecting flange E, is designed to fit between the nuts I, on the fish-plate
lts, the heads of which bolts are countersunk in the fish-plate J, and shaped so that
y will not revolve.
My improved chair may be made of any metal desired, but I prefer to make it of
ht steel.
When my improved chair is adapted to act in connection with a double headed
as shown in Figure 7, I arrange the chairs so that the bracing flange E. of each
[Price 6d1

page_text: chair shall be on alternate sides of the rail-first on the outside, then on the inside,
and so on, forming a solid brace which will effectually prevent the rail from tilting
towards either side. It will be observed in the application shown in Figure 7 that it
will be necessary to remove one spike F, in each two spikes in the chair, the latter
may be removed without disturbing the rail.
Having now particularly described and ascertained the nature of the said inven-
tion and in what manner the same is to be performed 1 declare that what I
claim is:
1) A rail-chair composed of a base designed to fit below the foot of the rail, and an
upwardly-projecting flange designed to fit against the bottom side of the head of the
rail, the junction between the upwardly-projecting flange and the base of the chair
being shaped to receive and grip one side of the foot of the rail; substantially as
aud for the purpose specified.
2) A rail-chair composed of a base designed to fit below the foot of the rail, and an
upwardly-projecting flange designed to fit against the bottom side of the head of the
rail and between the nuts of the fish-plate bolt, the junction between the upwardly-
projecting flange and the base of the chair being shaped to receive and grip one side
of the foot of the rail; substantially as and for the purpose specified.
