PROVISIONAL SPECIFICATION.
An Improved Method for Securing Rails to Chairs as Used on
Permanent and other Ways.
JOHN JAMES TAYLOR of 10 Clipstone Avenue Peel Street Nottingham
Engineer, do hereby declare the nature of this invention to be as follows:-
For the purpose of securing rails to chairs as used on permanent & other ways,
instead of employing wood, steel or iron keys in combination with the chair & loose
wedges, I form my improved chair in a determined number of pieces & preferably
with one jaw & the bottom plate cast in one piece, the opposite jaw being loose
& working through guides, these jaws when in position fit against the opposite
outer webs of the rails; to keep the spliced, point & wing rails in a crossing in
their correct position I employ loose pieces made to fit between the rails & by
means of a bolt or screwed rod with nuts, passing through these loose pieces & the
jaws, I am enable by screwing up to perfectly secure any rails from being displaced
from their proper positions, all parts "gripping" together.
Dated this 3rd day of October 1895.

An Improved Method for Securing Rails to Chairs as Used on
Permanent and other Ways.
I, JOHN JAMES TAYLOR of 10 Clipstone Avenue, Peel Street Nottingham,
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 :-
For the purpose of securing rails to chairs as used on permanent and other
ways instead of employing wood, steel or iron keys in combination with the
chair and loose wedge-I form my improved chair of a certain number of pieces,
and preferably with one jaw and the bottom plate cast in one piece; the opposite
jaw being loose and working through guides. These jaws when in position fit
against the opposite outer webs of the rails; to keep the splice, point and wing
rails of a crossing in their correct positions, I employ loose pieces made to fit
between the rails; and by means of a bolt or screwed rod with nuts passing
through these loose pieces and the jaws, I am enabled by screwing up, to perfectly
secure any rails from being displaced from their proper positions, all parts gripping
together.

In order that my invention may be fully understood, and more readily carried
out and into effect, I have appendel hereunto one sheet of drawings whereon
Figure 1 represents my improved chair in sectional elevation along line A. B
of Fig. 2-as made for flange bottom rails.
Figure 2 represents a plan of the same chair.
Figure 3 represents a cross section on line E. F.
Figure 4 represents my improved chair in sectional elevation along line C. D
of Fig. 5-as made for double-headed rails.

page_text: Figure 5 represents a plan of the same chair.
Figure 6 is a cross section view on line G H.
Figure 7 shows a railway crossing fitted with my improved chairs.
Similar letters of reference refer to similar parts throughout the various
figures.
In these figures, K is the chair-formed according to my invention-with one
jaw K' cast in one piece with the bottom plate, and having one or more loose
jaws L and L with their tongue pieces J. J sliding in the inclined or bevelled
guides shown in Figs. 3 and 6, into which they are inserted by dropping the jaw J
into the slot V in the chair K, and then sliding them along the guide until they
touch the rail R. In Figs. 1-2-3 and 7 the loose distance pieces T serve to keep
the rails R. R at the required distance apart for crossings, check rails, and the like,
and where two loose jaws L, L' are used-as in Figs. 4, 5 and 6-the rails R, R
are kept the required distance apart by the jaw K. The loose jaw or jaws, rails,
distance pieces and chair are firmly secured or tied together as shown by the
bolt N passing through them, and one or more lok nuts P, or cotter Q, or other
suitable fastening holding them all securely in place; when screwed or driven up.
In some cases I may use two or more bolts N to one chair; or I may use any
other and usual fastening for this purpose.
My invention is applicable to various kinds of railway chairs, including cast
iron sleeper chairs. Chairs of the kind shown in the drawings can also be
made to suit other distances and inclinations between the rails than shown.
In other cases I may insert leather or other suitable material between the jaws
and distance pieces to form an elastic cushion between these and the rails; and I
may also insert wood blocks into the space V to assist the bolt and nut N. P in
securing the chair to the rail or rails.
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 :-
1st. Railway chairs formed in one piece with one jaw K', in combination with
one or more loose jaws L, L' and fastening bolt and nut N. P; for the purposes
herein set forth, and substantially as hereinbefore described, and shown on the
drawings.
2nd. In railway chairs for the purposes mentioned the combination of one or
more loose jaws with a fixed jaw cast on the chair, and a fastening bolt or pin;
substantially as hereinbefore set forth and shown in the drawings.
3rd. The arrangement and combination of parts forming a railway chair as
herein before described and shown in Figures i to 7 inclusive herewith, for the
purposes, and substantially as hereinbefore described and set forth.
Dated this 18th day of February 1896.
