JOHN REBBLA 33.Foster St. New Brighton Morley in the County of York Tuner
do hereby declare the nature of my invention for THE FASTENING OF RAILS TO
THE CHAIRS FOR RAILROAD OR TRAMWAY LINES to be as follows:-
:-
The object of my invention been to enable the fastening of such keys or wedges
to be performed more effectively than heretofore the keys or wedges is made in
shape to fit the ordinary rail & chair now in use & and is made either in wood or
iron or other metals in a tapering form in thickness the front part of the keys or
wedges as a portion of it cut away from the centre or latter part to the opposite end
so as to receive a small key made of steel or iron which fits the part cut away &
projects out past the end of the larger key or wedge the other end of the smaller
key as a short bend on it in the shape of an L the large key or wedge been cut
away deeper to receive the bend or L which keeps the keys from becoming
detached endways when put together when put in the chair & driven up tight the
projecting part of the smaller key is bent partly round the jaw of the chair thus
keeping it perfectly safe from becoming detached, & leaving the lines or rails much
firmer.

I JOHN REBBLA of 33 Foster Street, New Brighton, Morley, in the County of
York, Loom Tuner, 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 :-
The object of my invention is to more effectually secure or fasten such keys or
wedges.
The keys or wedges are so shaped as to fit the (ordinary) rail and chair now in
use, and are made either in wood or iron, or in other metals, tapering widthwise
in the front part of the keys or wedges, a portion of it being cut away from the
centre or latter part to the end so as to receive a smaller key or wedge made of
steel or iron which fits the part cut away, and projects past the end of the larger
key or wedge, the other end of the smaller key or wedge has a short bend on it in
the shape of anthe larger key or wedge being more deeply cut away in order to
receive the bend or which prevents the keys or wedges from becoming detached
or slipping out end ways.
When put in the chair and driven up tight the projecting part of the smaller
key or wedge is bent partly round the jaw of the chair, thus preventing it from
becoming detached or slipping out endways,
DESCRIPTION OF DRAWINGS.
Fig. 1. shews a side elevation of an ordinary chair, rail in section, with my
improvements attached.
Fig. 2. shews a plan of Fig. 1.
Figs. 3. 45 and 5ª are detail views of my improvements.
Figs. 6 and 7 shew a modification of my invention, wholly in metal.
A is the rail (in section) B, B are the two jaws of the chair, C is the larger key
or wedge into which the smaller key or wedge D fits (as shewn in Fig 3.) and the
end of which smaller key or wedge D projects past the larger key or wedge C, as
sbewn in Figs. 2 and 3 and indicated by the letter E. When the said keys or
wedges are driven up tight the end E of the smaller key or wedge is bent round
the jaw B. as shewn in dotted lines in Fig. 2. which prevents the said keys or
wedges from becoming detached or slipping out end ways.
Figs. 6 and 7 shew a modification of my invention, the larger key or wedge A
and the smaller key or wedge B being constructed wholly of metal, the smaller key
or wedge B is slightly bent or deflected, and the larger key or wedge A is slightly
recessed, as shewn at C in Fig. 6. When the said keys or wedges are driven up
in the chair the bend or deflection of the smaller key or wedge is diminished, in
accordance with the extent of the driving up, the recess C allowing the said smaller
key or wedge B to assume a straightened condition. The larger key or wedge
may be dished out or cut away on the top and under sides as shewn at E E in
Fig. 7. in order to lessen the weight of the same.

page_text: Having now particularly described and ascertained the nature of my said
invention and in what manner the same is to be performed, I would have it
understood that I do not confine or limit myself to any particular form shape or
configuration of the bend or the portion of the smaller key or wedge which fits
into the larger key or wedge, (as the same admits of various modifications,) but
what I claim, I declare to be the following,
(1.) Forming in the larger key or wedge (or ordinary wooden block) a recess,
into which a key or wedge of metal is fitted, one end of which may be bent round
the jaw of the chair for the purposes herein specified.
(2.) The use and employment of a partly bent or deflected smaller metal key or
wedge, which fits into a recess in the larger metal key or wedge as shewn in Fig. 6,
for the purposes specified.
