PROVISIONAL SPECIFICATION.
Improvements in the Construction of Railway Stop-blocks.
I, CHRISTMAS LAWRENCE, of The Railway Foundry, Caerphilly, in the County
of Glamorgan, Engineer, do hereby declare the nature of this invention to be as
follows:-
This invention relates to railway stop-blocks, and consists in improvements.
whereby such structures are of simplified construction and of increased strength.
According to this invention, the headstock is secured to a pair of uprights
erected by turning up the ends of a pair of rails laid down outside and parallel..
with the rails of the railway. That is to say, an additional rail is laid at each end
to receive the headstock. The said additional rails extend forward from the front
of the headstock to a point where they are bolted to the rails of the track and
keyed in place. This distance exceeds the wheel-base of an ordinary railway
wagon or truck. The railway rails are, as is usual, extended back behind the
headstock, and to their rear ends are secured the lower ends of the inclined back
stays which at the other ends are fixed to the headstock and uprights. The
headstock is connected to the pair of uprights aforesaid by an angle iron situated
at the outside, which angle iron is cut and bent to serve as a support for the
headstock. The angle irons also brace the headstock to plates situated both inside
and outside at each end of the headstock. The back stays are, if preferred, tied
together by a bar inserted at each end in a chair and held by wedges. Behind the
headstock the railway rails are bent or turned outwards so as to bring them into a
plane corresponding to that of the back stays. The latter, in addition to being
bolted, as usual, to the headstock, are secured to the uprights by plates of which
there are two for each stay.

COMPLETE SPECIFICATION.
Improvements in the Construction of Railway Stop-blocks.
I, CHRISTMAS LAWRENCE, of The Railway Foundry, Caerphilly, in the County
of Glamorgan, 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 :-
This invention relates to railway stop-blocks, and consists in improvements
whereby such structures are of simplified construction and of increased strength.
According to this invention, the headstock is secured to a pair of uprights
erected by turning up the ends of a pair of rails laid down outside and parallel
with the rails of the railway. That is to say, an additional rail is laid at each side
of the ordinary track and turned up at one end to receive the headstock. The
said additional rails extend forward from the front of the headstock to a length
exceeding the wheel-base of an ordinary railway wagon or truck. The railway
rails are, as is usual, extended back behind the headstock, and to their rear ends
are secured the lower ends of the inclined back stays which are secured to the
headstock and uprights. The headstock is connected to the pair of uprights
aforesaid by an angle iron situated at the outside, which angle iron is shaped to
serve as a support for the headstock. In rear of the headstock the railway rails
are bent or turned outwards so as to bring them into a plane corresponding with

page_text: that of the back stays. The latter, are secured to the headstock uprights by
plates and bolts. The headstock is braced to the said plates by the angle irons
aforesaid.
Referring to the accompanying sheet of drawings, Fig. 1 thereon represents a
side elevation and Fig. 2 a plan of a railway stop-block constructed in accordance
with this invention.
The headstock a is connected to a pair of uprights provided at the back
thereof by turning up the ends of a pair of rails laid outside the rails c of the
ordinary track. The connection of the headstock to the uprights is inade by means
of the angle irons d and bolts d¹. The rails are extended forward from the stop-
block to any desired point distant therefrom a length exceeding that of the wheel-
base of a railway wagon, truck or carriage and are secured at or near such point to
the rails c of the track. The latter rails are, as is usual, carried back behind the
stop-block and, after having been turned under the inclined back stays e, are
connected thereto by the plates and bolts f¹.
The back stays e are extended upwards to the back of the headstock uprights
and are then bent over and continued down parallel and in contact with the
uprights to which they are connected by the plates h, h'. After having been
carried down below the bottoms of the rails c, the back stays are turned thereunder
at a right angle to the track.
The angle irons d, which brace the headstock to the plates h through the bolts i,
are turned under the headstock, as shown, and serve as supports thereto.
The method of construction above described combines strength with simplicity.
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 :-
A railway stop-block in which the uprights for carrying the headstock are
provided by turning up behind it a pair of rails laid outside and extending for a
suitable distance along the ordinary track; and in which the back stays, after
having been inclined from their rear ends up to behind the headstock, are bent
over and continued down parallel with the uprights and then turned under the
track; the connection between the headstock, uprights and back stays, and those
between the back stays and the rails, being made substantially as hereinbefore
described with reference to the accompanying sheet of drawings.
