I JOHN HICK, of Mytton Hall, Whalley, in the County of Lancaster, Gentleman,
do hereby declare the nature of said Invention for IMPROVEMENTS IN LOCKING
DEVICES FOR SECURING RAILS TO FISHPLATES, RAILWAY CHAIRS IN THEIR PLACES
AND FOR OTHER PURPOSES, which Invention has been communicated to me from
abroad by Thomas Richard Beaumont, of Georgetown, Colorado, United States,
Gentleman, and in what manner the same is to be performed, to be particularly
described and ascertained in and by the following statement:-
This invention consists partly in a novel combination and construction of the
parts of a locknut and bolt or screw device and partly in the method of applying
the same, the improved locking devices being particularly applicable to the
permanent way of railways or wherever the parts are subjected to strain and
vibration, the object of the Invention being to provide a locking device which will
firmly secure articles together and which will not shake loose when subjected to
vibration, but which can be readily released when required.
To effect this object when an ordinary bolt is employed, the nut is flanged to
form a combined washer and nut which may be used either alone as hereinafter
described, or in combination with a special washer provided with a spur or spurs
on one side and a bevelled surface on the other or side which is placed next the
nut. This washer is first placed. over the bolt with the spur downward and
bevelled face upward and the flanged nut is then screwed down thereby pressing
the spur into the wood or if applied to metals bringing the spur into a slot
prepared to receive it thus preventing the washer from turning. The flange of the
nut is then by hammering or otherwise bent over the bevelled part of the washer
thus effectually locking the nut on the bolt.
Instead of employing a washer as described the flanged nut may be used alone
by bevelling the surface of the metal or other material and forcing and bending
down the flange over such bevelled portion, thus locking the nut in position.
And in order that this Invention may be fully understood and readily carried
into effect I will describe the accompanying Sheet of Drawings, reference being
had to the figures and letters marked thereon.
Figures 1 and 2 are two views of this improved bolt which may be used either
with one of the special washers hereinafter shown and described under the nut or
in combination with a specially prepared or suitable surface. Figs. 3, 4, and 5 are
three views of the special washer as prepared for use on metal or other hard
surfaces. Figs. 6 and 7 are views of the special washer as prepared for use on
wood or soft surfaces. Fig. 8 is a view of a machine, screw or bolt made with a

page_text: flanged head according to this Invention and which may be used either with one
of the said special washers or in combination with a specially prepared or suitable
surface. Figs. 9 and 10 are detailed views of one of the flanged screw nuts.
Fig. 11 is a view illustrating this Invention as applied to a screw spike with a
coarse thread used to secure railway chairs to their sleepers and for other
purposes; this screw spike may also be used in combination with one of the
special washers or otherwise as described. Figs. 12 and 13 are views of part of a
railway rail and fishplate joint to which this Invention is applied and Figs. 14
and 15 are views of a bolt or screw spike made with a flanged head according to
this Invention and employed to fasten down a railway chair or other article; the
lug in this case being shaped or bevelled on the surface at one side according to
this Invention.
It is evident from the foregoing description that the flanged locknuts and bolts
may be used either with or without the special washers according to the conditions
under which they are employed.
The bolt a with the flanged nut b shown in Figs. 1 and 2 is in Figs. 12 and 13
represented as applied to a fishplate joint, c c being the fishplates and d the rail.
The nut is screwed up tight on the bolt and firmly locked in its place by
hammering or forcing the flange b' over the edge of the fishplate c, no loose washer
being required in this case. If desired, the bolt might be made with a flanged
head (see Fig. 8) and the flange bent over the fishplate c¹ thus forming. a double
lock.
No vibration or movement of the parts can shake the bolt loose but when
required the nut b can be readily released with a wrench or spanner in the
ordinary manner.
It is obvious that no special preparation of the surface is in this case necessary,
the shape of the fishplates c c¹ being already adapted for the purposes of this
Invention.
1.
Having now particularly described and ascertained the nature of this said
Invention and in what manner the same is to be performed I declare that what
I claim is
1. The improved locking devices consisting, first, of the combination with a
bolt made either with or without a flanged head, of a flanged nut and a specially
prepared or suitable surface, secondly, of the combination with a bolt made either
with or without a flanged head, of a flanged nut for securing rails to fishplates
thirdly, of the combination with a bolt made either with or without a flanged
head, and a flanged nut of a special washer formed with a shaped or bevelled'
surface on the side contiguous to the said nut and provided with a spur or spurs'
on the other or opposite side'; fourthly, of the combination with a screw spike of a
flanged head used in conjunction with a specially prepared or suitable surface, and
fifthly, of the combination with a screw spike formed with a flanged head, of a
special washer as above defined. The several combinations and constructions of
parts being all substantially as and for the purposes herein before described and as
illustrated by the Drawings annexed.
!
2. The method of locking the flanged nut of a bolt, the flanged liead of a bolt,
or the flanged head of a spike by means of forcing and bending said flange over
and upon a specially prepared or suitable surface which may or may not be formed
on one of the special washers, all substantially in the manner herein set forth for
the purposes specified.
