PROVISIONAL SPECIFICATION.
Improvements in Railway Chairs and Fastenings.
I, HENRY WALKER HILL of 47 Hampden Street, Nottingham, Consulting and
Mechanical Engineer, do hereby declare the nature of this invention to be as
follows:-
The object of my invention is to provide improved chairs and fastenings for
securing vignoles, and other forms of rails thereto.
For this purpose, I form on the upper side of the chair, a rib or clip having a
groove or recess on its inner side, for one side of the rail flange or the rail to
enter in the ordinary manner; and for securing the other side of the rail flange
or rail, I form a dovetailed or other suitably formed recess across-or nearly
across the upper part of the chair, near to and alongside the rail; and I also
form a projecting rib with an outwardly inclined face-running alongside this
recess.
I have a strong clip or clamp formed on one side with an inclined face of the
same angle as, and bearing against that of the inclined projecting rib on the chair;
the other side of the clip or clamp is recessed or suitably formed to bear against
the edge of the rail flange or rail. Passing through this clip or clamp, I have one
or more bolts with the head or heads made of the same form as the recess in the
chair, and fitted with one or more self-locking nuts, or with ordinary nuts, cotters
or other suitable fasteners, in such a manner, that when the nut or other fastener is
screwed down on to the clip or clamp, the inclined surface of the clamp slides
down that of the inclined rib, and causes the other side of the clamp to hold the
rail firmly partly in a downward direction on the chair, and also in a lateral
direction, by forcing it into and against the rib or clip formed on the chair on the
opposite side of the rail.
In some cases, I may form the clip or clamp with a dove-tailed projection on
its underside, to slide into the recess in the chair; and fastened thereto by a
suitable taper wedge or key driven in between the projection on the clamp, and the
side of the recess in the chair.
Dated this 23rd day of April 1892.

COMPLETE SPECIFICATION.
Improvements in Railway Chairs and Fastenings.
I, HENRY WALKER HILL of 47 Hampden Street, Nottingham, Consulting and
Mechanical 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 :—
The object of my invention is to provide improved chairs and fastenings for
securing vignoles, and other forms of rails thereto.
For this purpose, I form on the upper side of the chair a rib or clip having a
groove or recess on its inner side for one side of the rail flange or the rail to
enter in the ordinary manner; and for securing the other side of the rail flange
or rail, I form a dovetailed or other suitably formed recess across or nearly
across the upper part of the chair, near to and alongside the rail; and I also
form a projecting rib with an outwardly inclined face-running alongside this

page_text: I have a strong clip or clamp formed on one side, with an inclined face of the
same angle as, and bearing against that of the inclined projecting rib on the chair;
the other side of the clip or clamp is recessed or suitably formed to bear against
the edge of the rail flange or rail. Passing through this clip or clamp, I have one
or more bolts with the head or heads made of the same form as the recess in the
chair, and fitted with one or more self-locking nuts, or with ordinary nuts, cotters
or other suitable fasteners, in such a manner, that when the nut or other fastener
is screwed down on to the clip or clamp, the inclined surface of the clamp slides
down that of the inclined rib, and causes the other side of the clamp to hold the
rail firmly partly in a downward direction on the chair, and also in a lateral
direction by forcing it into and against the rib or clip formed on the chair on the
opposite side of the rail.
In some cases I may form the clip or clamp with a dove-tailed projection on its
underside, to slide into the recess in the chair; and fastened thereto by a suitable
taper wedge or key driven in between the projection on the clamp, and the side of
the recess in the chair.
In order that my invention may be fully understood, and more readily carried
out and into effect, I have appended hereunto one sheet of drawings whereon:-
Figure 1 represents my improved chair in elevation, and partly in section.
Figure 2 represents a plan of the same chair.
Figure 3 a side or end view of the chair.
Figure 4 represents an elevation of my improved fastening.
Figure 5 shows a plan of the fastening.
Figures 6-7-8 and 9 represent various views of the form of bolt and locking
nut I prefer to use with my improved chair and fastening.
Similar letters of reference refer to similar parts throughout the various
figures.
In these figures H is the rib or clip formed with a recess for receiving one side
of the rail F. B is a dovetailed or other suitably formed recess on the upper side
of the chair A running partly across it; and having a projecting rib K with an 3
outwardly inclined face I running parallel with the recess B. C is a strong clip or
clamp forming my improved fastening, and having an inclined face L (Fig. 4) of
the same angle as, and bearing against the inclined face I on rib K; the other
side of the clamp C has a recess M formed along its face, so as to fit the flange of
the rail F. D is the bolt passing through clamp C, having its head N of the same S
form as the recess B.
The bolt D is fitted with a self-locking spring nut E-which forms no part
of my invention or with an ordinary nut, cotter or other suitable fastener.
The action of the whole arrangement is such that when the nut E is screwed
down on to the clamp C, the inclined face L of the clamp slides down the inclined 4
face I on the rib K, and causes the side M of the clamp C to hold the rail F
firmly on the chair A-partly in a downward direction on to the chair, and partly
in a lateral direction by forcing it into the recess under rib H.
My invention is applicable to various kinds of railway chairs, including cast
iron sleeper chairs. of the kind shown in the Figures 1, 2 and 3 can of 4
course be made to suit different distances and inclinations between the 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. In railway chairs, forming them with one or more slots B, one or more 5
inclined ribs K, in combination with one or more fastenings C bolted to the chair į
for the purposes herein set forth, and substantially as hereinbefore described, and
shown on the drawings.
2nd. The improved railway chair and fastening, in which are combined in each
case a cast iron chair, one or more fasteners C shaped to bear against the edge 50

page_text: and upon the top of the bottom flange of a vignoles or other bottom-flanged rail—
at one side of the fastener-and against an inclined face I at the other side of the
fastener, and one or more bolts & nuts for attaching the fastening to the chair;
all for the purposes herein set forth, and substantially as herein before described
5 and shown on the drawings herewith.
Dated this Twenty-fourth day of January 1893.
