Improvements in Chairs and Railway Joints, and Means for Securing
the Rails therein.
GEORGE FREDERICK MARTIN, 154, Southampton Road, Eastleigh, 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:-
This invention consists of improvements in chairs & railway joints and
means for securing the rails therein, the object being to provide secure means
of retaining rails in the chairs, and at the same time giving an easy running
joint.
In carrying out my invention, I provide two pieces of suitable material such
as metal, which are placed one upon each side of the rail in the chair which
is shaped and adapted to receive them. One of these pieces is provided with
a projection which engages in a corresponding recess in the chair, a spring pin
being employed for locking same in position when required. The ends of the
rails where they meet are slotted or cut so as to form when together a square
or other shaped recess into which a projection formed upon one of the pieces
preferably upon that which is known as the inside of the rail, engages or fits.
By this means a wheel in passing over a joint will bear directly upon the pro-
jection aforesaid, thus reducing the jolting when passing over a junction of
rails to a minimum.
The chair, rail, and securing pieces aforesaid may be bolted together in any
convenient & well known manner.
For purposes of illustration, I will now refer to the annexed drawings in
which:-
:-
Figure 1, is a perspective view of my improved chair.
Figure 2, view of metal piece for insertion between the rail & chair.
Figure 3, view of locking pin.
Figure 4, view of form of piece for insertion between the rail and chair
having the projection thereon.
Figure 5. plan view of arrangement for connecting the ends of the rail
together.
Figure 6, vertical section through line -y in Figure 5.
Fig. 7 perspective view of rail ends showing cut away portions.
Fig. 8, perspective view of locking piece h.
Referring to Figure 1 & 6 the chair is provided with a recess a in which
the projection b on the locking piece c engages. The wedged shaped pin e
is provided with the flexible metal piece f & is inserted between the locking
piece & the part of the chair. The metal piece is then bent so as to pre-
vent the pin from becoming disengaged.
By this arrangement it will be seen that the ordinary wedges are dispensed
with as the locking piece cannot be disengaged owing to the engagement of
the projection upon the recess in the chair and by driving the wedge shaped

be
The ends of the rail are cut as shewn in Fig. 5 & 7, and the piece h is pro-
vided with a projection i which fits into a recess or slot in the ends of the
rails. The locking piece c is secured by means of the wedge shaped pin e.
The projecting part 2 upon the piece h prevents the shock or jar which occurs
when a train or the like is passing over the ends of the rails.
If desired, the parts may be bolted together, in the ordinary way.
Although for purpose of illustration I have shewn this particular arrange-
ment of parts, it will be readily understood that there may be slight modifica-
tions in the shape of such parts without departing from the object of my
invention.
Having now particularly described & ascertained the nature of my said in-
vention, and in what manner the same is to be performed, I declare that what
I claim is:-
1. In means for securing rails & chairs: a locking piece having a projection
which engages in a recess in the chair; a wedge shaped pin having a strip of
flexible material which is driven between the locking piece and the chair;
said strip of flexible material being bent so as to secure the pin in the desired
position, a plate or piece shaped & adapted with a projection which engages
in recesses formed in the meeting ends of the rails for the purpose of reducing
jar or shock between the wheels & rail, substantially as described & illustrated
herein, and for the purpose set forth.
2. The combined construction and arrangement of the various parts sub-
stantially as described & illustrated herein & for the purpose set forth.
