I, JOSEPII HENRY BETTELEY of 42 Old Broad Street, in the City of London,
Engineer do hereby declare the nature of my invention for "IMPROVEMENTS
IN SECURING THE PERMANENT WAY OF RAILWAYS, AND WHICH MAY BE MADE
APPLICABLE TO OTHER PURPOSES to be as follows:-
"
My Invention has reference to the novel construction of, firstly:-A washer for
the purpose of locking the nut, and, secondly :-of a wedge of novel construction
for securing the key in the chair in position, and preventing its shifting, as
hereinafter described.
I design the washer as before mentioned of any suitable metal, and stamp or
otherwise make, an indentation or depression across its diameter, for the purpose to
be described hereafter. Around its periphery I further make several slits or cuts,
so as to form tongues.
The object of the depression or indentation is that it shall fit into a corresponding
depression or indentation in the fish plate, which depression can be made either
when the fish plate is being rolled, or on existing and ordinary fishplates, by means
of a cold chisel or fuller.
After the nut has been screwed home, the washer becomes firmly fixed in
position, and in order that there may be no loosening of the nut by vibration,
I bend up one or more of the aforesaid tongues against the sides of the said nut,
thus effectually locking both nut and washer.
In respect of the before mentioned wedge, according to my invention, I take a
plate of metal of suitable width and thickness, and bend one end at right angles,
which forms a head-piece for the reason hereinafter described. This plate of metal
with its aforesaid bent head-piece, shall have the same length as the wooden key
ordinarily in use. The other end of the before mentioned metal plate, I design to
taper, split, cut or otherwise fashion it. I also bend it either along its length, or
its width in order both to increase its elasticity, and to ensure a certain amount of
spring.

page_text: In fixing the key, I place the bent metal plate against the said key; the bent
head-piece aforesaid covering and protecting the head of the key from injury
whilst being driven home; when the key and the accompanying wedge are firmly
fixed in position, I bend the other or tail end of the aforesaid plate or linen against
the side of the chair, which effectually prevents either the key, or the wedge from
shifting.
Should however the key as aforesaid become loosened by vibration or atmo-
spheric variations, it is only necessary to drive both home until again firmly fixed,
and then rebend the tail end of the plate or liner against the chair.

JOSEPH HENRY BETTELEY Engineer of 42 Old Broad Street in the City of
London do hereby declare the nature of my invention for IMPROVEMENTS IN
SECURING THE PERMANENT WAY OF RAILWAYS &C and in what manner the same
is to be performed, to be particularly described and ascertained in and by the
following statement :-
My invention has reference to the novel construction of Firstly; a washer for
the purpose of locking Nuts, and Bolts, and Secondly, of a wedge of novel
construction for securing the key in position of Railway chairs as hereinafter
described, and represented, and for other work where required.
I design the washer as before mentioned of any suitable metal, and stamp, or
otherwise make, one, or more projections on the face of the same for the purpose
to be hereinafter described; around its periphery I further make several cuts, or
slits, so as to form tongues.
The object of the aforesaid projections is for securing the washer in its place,
suitable indentations being made on the surface of the metal to receive the
projections, but when used on wood, or other plastic substances, the projections on
the washer will make the required indentations by pressure, in the act of screwing
up the Nut, or Bolt.
After the Nut, or Bolt, is screwed home, the washer becomes firmly fixed in
position, and in order to lock the Nut, or Bolt, I bend up one, or more of the
aforesaid tongues against the side of the Nut, or Bolt, which will prevent the Nut,
or Bolt, from being unscrewed, but when the ordinary washer is used having a
radial or diametral indentation or impression, I bend up a portion of the same for
securing the Nut, or Bolt, as shewn in the accompanying drawings,
Secondly in respect of the before mentioned wedge for securing the key in
Railway chairs, I take a plate of metal of suitable width, and thickness, and bend
one end of the same to a right angle, which forms a head piece to protect the bead
of the key; and the other end, I taper; cut, or split, into one, or more parts to
form tongues for the purpose hereinafter described I also bend it, if advisable,
either in its length, or width to give it elasticity, or spring, in order that the
pressure of the wedge, through its spring, or elasticity may be continued to a
certain extent against the key, to counteract the effect of shrinkage in the key.
In fixing the wedge, I place its head piece against the head of the key to protect
it when being driven home whilst the face of the wedge protects the key from
being cut into by the edge of the chair, and when wedge, and key, are driven home,
I then bend one of the tongues formed at the other, or, tail end of the wedge,
downwards against the key, and another of the tongues upwards against the chair,
chus securing both the wedge, and, key in the chair.
The aforesaid wedge may be applied in a similar manner for securing other keys
of metal, or other material, for other purposes, than that of keys of Railway chairs,

page_text: In order that my Invention may be clearly understood I will proceed aided by
the accompanying drawings more fully to describe the same,
Fig. 1 is an elevation of a Rail shewing the Fish plates and chairs in position:
where a, represents the metal wedge, and b, the. key, and al represents one tongue
of the wedge bent up against the chair, and a another tongue bent down against
the key-c, is a stop to prevent the wedge and key being driven too far.—d, is the
serrated washer, and d', is the washer with one tongue bent up against the Nut,
for locking the same, e, is a plain washer; and f, represents the indentations in the
Fish plate. Fig. 2, is a plan view-of- Fig. 1.-Fig. 4, is the end view of Rail and
chair. Fig. 3, is the end view of Rail, and Fish plates.-Fig. 5, is a plan view of
the wedge, and Fig. 6, is the edge view of the wedge representing it as bent
- longitudinally to give it elasticity or spring. Fig. 7, is the end view of the
wedge. Fig's. 8, and 9, are edge views of wedges, showing the bends.for elasticity,
made in them transversely.-Fig. 10 represents the serrated washer, with two edge
views, c, and f-Fig. 11 represents a plain washer, to be used for woodwork with
conical projections shewn at g, g, and 'h, represents the edge view of the same.
Fig. 12, represents a Nut, locked by a portion of an ordinary washer bent up
against the side of a Nut, and, where i, and j,'are plan and side views respectively.
and represents the projection-Fig. 13, represents a Nut, locked by a portion of
an ordinary washer bent up into a hollow formed in the under odge of the side of
the same, while k, and l, are plan, and side views, respectively and ³ represents
the projection-Fig. 14, represents an ordinary washer, bent up into a recess
formed on the under side of the Nut, and m, represents a plan view of the same
and represents the projection - Fig. 15, represents a coach screw, locked by a
washer with a portion of the same bent up against the side of the head of tho
coach screw. Fig's. 16, and 17, represents an edge and plan view respectively of a
washer to be secured by bending a portion of the same under the Fish plate.-
Fig. 18, represents coupled washers, which may be made in one picce as shewn, or,
in two parts, with a suitable joint between them.-Fig. 19, represents modern
designed Fish plates, and with these plates, the washers having tongues or slits
may be secured, by making them square at their lower parts, as shewn.
Having now particularly described and ascertained the nature of my said
Invention, and in what manner the same is to be performed I declare that what
I claim is
Firstly. The locking of Bolts, and Nuts, by the aid of a washer of any suitable
material, with one, or more projections on the face of the same, as described and
represented in Fig's. 1, 2, 3, 10, 11, 12, 13, 14, and 15,-and for locking Bolts, and
Nuts, with washers made, as shewn, and represented at Fig's. 16, 17, 18, and 19.
Secondly. The metal wedge for locking and protecting keys in Railway chairs,
as described and represented in Fig's. 4, 5, 6, 7, 8, and 9,-and for securing other
keys, in other work where required.
