Improvements in or connected with Spikes and Rolts for Securing
Railway Chairs.
I, GEORGE ASHTON BROOKES of West View, Higher Poynton, Cheshire, 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 an improved spike for securing railway chairs to
sleepers, and is intended to provide a spike which will not be liable to get loose.
In carrying out my invention I propose to make the spike in three main parts,
the central one of which consists of a wedge driven in between the two sides which
form the main part of the spike. These two side pieces which are formed with
heads projecting at one side are provided with a wedge shaped groove in their
inner faces. The central wedge is preferably longer than the side spikes and
after the latter have been placed in the sleeper the end of the spike is inserted in
the grooves, and is then hammered down. This forces the sides apart, and causes
the spike to wedge itself firmly in the wood.
According to a modified arrangement a screwed socket provided with a plate is
placed in a recess formed in the lower side of the sleeper, and the pin is screw
threaded to fit the socket and provided with a square or other head. To secure
the pin it is passed through a hole in the sleeper until its end projects into the
end of the socket into which it is screwed tightly. This arrangement also
prevents any danger of the pin or bolt becoming loose.
In order that the invention may be more clearly understood, reference is had
to the accompanying sheet of drawings, in which Fig. 1 shows one form of my
improved railway spike in section, Fig. 2 shows the parts separate, and Fig. 3 is
a modification.
Referring to Figs. 1 and 2, the two side pieces or spikes A are employed, having
the heads a. Between these two spikes or side pieces the central wedge B is
placed fitted into the grooves a¹ in the inner faces of the pieces A. This central
wedge forces the, side spikes apart and causes them to bite in the wood.
According to a modification shown in Fig. 3, the socket C is employed, having
the plate or socket c. This socket is screw threaded internally, and is placed in a
recess in the sleeper. The pin D is also screw threaded and provided with the
head d allowing it to be passed through the sleeper and to be screwed into the
socket.
Having now particularly described and ascertained the nature of my said in-
vention and in what manner the same is to be performed, I declare that what I
claim is :-
(1) An improved railway spike formed from two side pieces and a central wedge
adapted to be forced between the two pieces, substantially as and for the purposes
specified.
(2) The improved railway spike formed from two side pieces each having a
wedge shaped groove in its inner face, and a central wedge adapted to be inserted

page_text: between the two side pieces, substantially as described and shown in Figs. 1
and 2 of the accompanying drawings, and for the purposes specified.
(3) An improved railway fastening, consisting of a screwed socket fitting into
the lower part of the sleeper, and a screwed pin or bolt passing through the
sleeper and screwing into the socket, substantially as described and shown in 5
Fig. 3 of the drawings, and for the purposes specified.
Dated this 26th day of March, 1897.
