Improvements in and connected with Chairs for the Permanent Way
of Rail and other like Ways.
L. BENJAMIN RAMSDES, Crofton House, Greetwell, Lincoln, Gentleman, 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
statment:-
My invention relates to improvements in and connected with chairs for the
permanent way of rail and other like ways, and the objects are to prevent
movement of the chair and consequently to obviate the unevenness caused by
the present chair: to prevent wet and grit getting to the spikes; to keep the
sleepers dry to give the key greater hold, and to prevent it falling out.
It is well known that the ordinary chair owing to its insuflicient base works
itself into the sleepers, and that the rain water and dirt getting into the cavity
thus formed, finds its way down the spike holes, and a churning motion is set up
by the passing traffic, the consequence being that the spikes begin to work up-
wards and once loose, they can never be made properly fast again.
The existing chairs are not broad enough to ensure a good grip of the sleepers,
and the keyways are not sufficiently long to keep the keys in position for any
length of time."
My new chair has a longer keyway than usual, and has also an opening in it
to enable a split pin or the like to be inserted in a hole provided in the key for
the purpose of preventing the latter working out of the chair.
The essential features of my new chair are. a keyway of greater length than
usual: a broad base having downwardly overlipped ends for clipping the upper
part of the sleeper; providing the upper surface of each base with a channel for
catching the wet and running it off over the overlipped parts already mentioned..
My invention also includes the provision of a slot or equivalent in the keyway
side of the chair for the purpose of allowing a split pin or the like to be inserted
therethrough, and driven into the key or passed into a hole provided therein for
its reception, the object being to prevent the key working out. In connection
with my improved chair. I employ holding down spikes of special form, the
spikes being constructed with a screw thread of quick pitch, and also with a
Square head.
In order that my invention may be the more readily understood, 1 make
reference to the accompanying sheet of drawings in which. Fig. 1, is a front
view, Fig. 2, a side view, and Fig. 3, a plan of my improved chair. Fig. 4, is
a side view of my improved spike. Similar letters indicate the same parts where
they occur.
a is the base having the overlipped ends and the channels c. d is the key
keeping the rail e in place in the chair. f is an opening in the keyway through
which the split pin or equivalent g can be driven into to keep it from falling
out or moving longitudinally for a greater distance than the length of the
opening is the sleeper, and the spike which has the quick pitched screw

page_text: thread and the square head &. The spike is driven home in the ordinary
manner, a final turn being given by the head to ensure its taking hold of the
sleeper securely.
I de not confine myself to the precise shapes, dispositions and relative pro-
portions of the various parts shewn in the drawings or mentioned in the specifica-
tion, as any or all of them may be considerably varied without departing from
the spirit of the invention.
Having now particularly described and ascertained the nature of said
my
invention and in what maner the same is to be performed, I declare that what 1
claim is:
CLAIMS.
1. In chairs for the permanent way of rail and other like ways, constructing
the base with greater length than usual and providing it with downwardly over-
lipped fore and aft ends for clipping the top edge of the sleepers, the whole
substantially as described in the above specification and excimplified in the
accompanying drawings.
2. In chairs for the permanent way of rail or other like ways, providing the
base with channels for running off water falling theroon, the whole substantially
as described in the above specification and exemplified in the accompanying
drawings
3. In chairs for the permanent way of rail or other like ways, providing the
keyway with an opening through which may be passed a split pin or equivalent
destined to be driven or otherwise inserted into the key, the whole substantially
as described in the above specification and exemplified in the accompanying
drawings.
4. For use in holding down to the sleepers chairs constructed in accordance
with the above claims, spikes having square heads and a quick pitched screw
threaded shank, substantially as described in the above specification and exem-
plified in the accompanying drawings.
5. The improvements in and connected with chaire for the permanent way of
rail and other like ways, provided for substantially as described in the above
specification and exemplified in the accompanying drawings.
