Complete Specification Left, 18th June. 1900-Accepted, 28th July, 1900
JOHN EARNSHAW LEACH, Gentleman, 3, Selborne Terrace, Bradford Road,
Shipley, Yorks, do hereby declare the nature of this invention to be as follows:-
The improvement consists of making the chairs in two separate parts, which
are secured in position by a wrought iron cotter, or wedge, which have a series
of holes bored to receive a split pin, this prevents the wedge, or cotter, from
falling out.
The jaws is then drawn up and fixed in position by the cotter, or wedge, on
the top side of chair, by this system, the inside jaw, is left perfectly loose, and
can be taken from together, when the cotter, or wedge, is driven out, by this
method no wood keys are required.
Dated this 18th day of September 1899.
I, JOHN EARNSHAW LEACH, of 3, Selborne Terrace, Bradford Road, Shipley,
in the County of York, Gentleman, do hereby declare the nature of this inven-
tion 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 improvements in railway chairs, and its primary
object is to dispense with the wooden wedges or keys at present largely in use.
To fully describe my invention, reference is made to the accompanying sheets
of drawings, forming a part of this specification, in which similar figures of
reference indicate corresponding parts in each of the views.
Figure 1, is a plan view of one of my improved chairs with a portion of a rail
shown therein.
Figure 2, is a section of the same on the broken line a, b in the former figure.
Figure 3, is an end view.
Figures 4 and 5 are two separate views of the loose jaw employed.
Figure 6, is a plan view showing the modified form of chair adapted to hold
the fish plates as well as the rail at a joint in the rail.
Figure 7, is a section of the same on the broken line y, z.
The base 2 of the chair is made to be secured to the sleeper in the usual way,
but is only made with one fixed jaw 3. The other jaw 4 is made loose, and it-
base 5 is made to fit and slide between the cheeks or guide pieces 7 formed on
Di Q77

page_text: the top of the base 2. Horizontal slots 8 are made through the cheeks 7 to
receive the metal wedge 10 one edge 12 of which bears against the back 13 of
the loose jaw, and when the wedge is driven in forces such jaw firmly against
the rail 14 and the rail is therefore tightly gripped between the two jaws.
A series of holes 15 may be drilled in the end of the wedge and a split pin 20
slipped into one of them to prevent the wedge shaking loose.
In Figures 6 and 7 the shape of the jaws is modified as shown to receive the
fish plate 30 as well as the, rail 14..
Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is:
The combination with the chair having a fixed jaw 3 of the loose jaw 4 and
the wedge 10 for the purpose specified, substantially as herein shown and
described and illustrated in the accompanying drawings.
Dated this 14th day of June 1900.
