Improvements in Chairs for Railway Rails.
I, JOHN WHITTLE, of 27 Frampton Place, Boston, Lincolnshire, 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
statement :-
This invention has for its object, the construction of chairs for the permanent way
of railways by forming them of a novel shape of base to give greater rigidity and
security when fixed to the transverse sleepers without reduction of strength or
surface as weight supports for rails, said chairs being intended chiefly for the wavy
faced scarf jointed rails, forming another application for Patent under number
17410 of the present year, or for intermediates of the said rails, or for ordinary
kind of rails.
The base of my new chair has extended horns from the sides, and may be varied
and have one end of greater width than that of the other end. The broader end
consists of two segmental extremities with narrowed neck where they merge into
the rail support with the extension horns and has two spike or trenail holes, the
narrow end having one bolt or spike hole, the cheeks of the chair rising up in the
ordinary way for the rail ends to be secured by the usual key.
By this invention, the horns and the tread or bearing surface of the chair ensure
a level and more extended surface for the rail to rest upon and give greater security
against the rails jumping under the intermittent thrusts imparted by the wheels due
to the varying loads passing over the metals.
The invention will be clearly understood by the annexed drawings.
Figure 1 side elevation, and Figure 2 plan of chair with wide tread and horns for
splayed foot rail of any kind but preferably for the rails with scarf ends, or with
rails having increased metal on the outer surface and with wavy faced inner
surfaces as described in my previous application for Patent No. 17410 of the
present year.
Figures 3 and 4 are similar views of another chair of my invention with some-
what narrow tread and horns chair for the ordinary double tee or double headed
rail. A the base. B the tread. C, C, the horns projecting therefrom.
D, D, cheeks. E, E, E, spike or trenail holes. F, the key, and G the rail.
The horns I purpose making of such length as to correspond to the width of the
transverse sleepers on which such chairs have to be fixed, so that by their length
the rails are supported on a much longer surface than is usual, and which gives
greater stability to the permanent way, and consequently greater security to the
rolling stock.
If my chairs be used for the ends of the rails which I consider very desirable,
I can dispense with fish plates, and one key will fix both the ends of two
adjoining rails.
I may observe that my chairs correspond in weight with existing chairs but
instead of having what I term useless metal, such as is indicated by the dotted lines,
I form the horns and utilize the said metal for supporting the rail both in front
and behind the cheeks and obtain more bearing surface for steadiness and
distribution of pressure over a large area.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed I declare that what I
claim is :-
1. The construction of railway chairs with extensions or horns as continuation of

page_text: the tread or bearing surface, as described and as shown on the annexed drawings
for the purposes set forth.
2. Constructing chairs (for railways) with narrowed necks between spike holes
and rail seating, and utilizing the weight of metal otherwise so used, as horns or
extensions of the tread or seating from either side, as set forth.
