PROVISIONAL SPECIFICATION.
An Improved Combined Joint and Intermedial Railway Chair and
Apparatus for Securing the Rails thereto.
GEORGE FREDERICK MARTIN of No. 154 Southampton Road Eastleigh in the
County of Hants Smith and Fitter do hereby declare the nature of this invention
to be as follows:-
My Invention relates to an Improved Combined Joint and Intermedial Chair,
and the combined apparatus connected therewith for securing the rails to the
chair as the different circumstances arise. The first part of my Invention consists
of a peculiarly formed Chair A having a wide bearing base, with two sides or arms
of two different shapes or forms to support and keep the rails in a firm position (a)
One side of the arm or support b, is hollowed out near the Base to allow the bottom
bead or flange of rail to fit in, and is then carried to a certain height for the web
of rail to rest against, which part of arm or support is narrowed to a certain
width above the hollowed part to the top of the arm; (b) the other side of the
chair c is carried up from the base vertically to a certain height in which part of
side of arm a rectangular pocket h, is formed, and above the pocket it is both
narrowed in width and hollowed out towards the top of arm thereby forming a
cavity for the wedge n. to fit in, the whole is constructed of Cast Metal.
Under the second part, two steel plates p. o. are used of different shapes or forms
having elongated holes, thereby allowing greater facility for contraction and ex-
pansion of the rails, p. being made to fit between the hollow part of chair and the
Hange or bead of rail the other, o is of a different shape or form and thicker to
allow for a square counter sunk bolt head.
Under the third part I use a peculiarly shaped Key d with a projection i at the
back corresponding to the size of rectangular pocket in the arm of chair e pre-
venting the key from sliding through the arm of chair which is so prevalent with
the ordinary Oak key through shrinkage, the said Key d can be made with a
hollow portion in front to admit of a block of Oak inserted endways to face rail or
other compressible substance, and also made of solid malleable Iron or Steel.
Under the fourth part I secure the foregoing apparatus, which being used under
different circumstances with a spring wedge n which is made of a certain form
with a recess to allow the spring portion to lie in that recess in order to protect
the spring as much as possible when driven either in or out of the arm of chair,
this said wedge can be made of Steel or Iron.
The Method of using the chair (a) when the chair is to be used as a joint chair
the two ends of different rails are placed on the centre of the bed of chair, the
plates are then slipped in the sides apportioned for each plate which are then
bolted together, the top part of the arms of the chair being made of a certain width
allows the bolts and nuts to be freely used and is then tightly secured by the
wedge n. (b) when the chair is used as an Intermedial chair the Key d is inserted

page_text: between the rail and that part of the arm of chair with the rectangular pocket
into which it is placed and is securely fastened by the spring wedge passing over
the projection thereby tightening the key and rail against the opposite arm of
chair.

An Improved Combined Joint and Intermedial Railway Chair and
Apparatus for Securing the Rails thereto.
I, 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 relates to an improved combined joint and intermediate railway
chair and apparatus for securing the rails thereto, as described in my Provisional
Specification, and 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 locking piece.
Figure 3. view of metal piece for insertion between the rail and chair.
Figure 4. view of locking pin.
Figure 5. view of modified form of piece for insertion between the rail and chair.
Referring to Figure 1, the chair is provided with a recess a in which the pro-
jection 6 on the locking piece c engages. The rail is carried between the part d
of the chair and the locking piece. The wedge-shaped pine is provided with the
flexible metal piece f and is inserted between the locking piece and the part g
of the chair. The metal piece is then bent so as to prevent the pin from becoming
disengaged. I sometimes find it convenient in certain positions to employ the
modified forms shewn in Figures 3 & 5 for the purpose of joining the two ends of
the rails together. The pieces c¹ & d¹ are placed on either side of the rail &
secured by means of bolts passing through the holes shown. By this arrangement
it will be seen that the ordinary wedges are dispensed with as the locking piece
cannot become disengaged owing to the engagement of the projection b upon the
recess a in the chair and by driving the wedge-shaped pin in as required the parts
will be held in position, and the pin may be secured when driven in by bending
the flexible metal piece.
Although for purposes of illustration I have shewn this particular arrangement
of parts; it will be readily understood that there may be slight modifications in the
shape of such parts without departing from the object of my invention.
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:
1. In chairs or locking mechanism for the ends of rails. The combined con-
struction and arrangement of the various parts substantially as described and
illustrated herein.
2. In means for securing rails and chairs: a locking piece having a projection
which engages in a recess in the chair; a wedge-shaped pin having a strip of

page_text: 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.
