page_text: I, HENRY ARTHUR GADSDEN, of 6 Crosby Square, Bishopsgate, in the City
of London, Merchant, do hereby declare the nature of this invention to be as
follows:-
This invention relates to means for securing in place bolts or nuts, and keys or
wedges such as are used for fastening ends of rails together or in railway chairs
and like purposes.
A piece of metal such as sheet iron or soft steel of any suitable shape has formed
through it a hole or holes large enough to slip over a bolt or bolts and to form an
arm or tail piece or arms or tail pieces of any desired length for the purpose of
being nailed or otherwise secured to wood or other material, or the arm or tail
piece or arms or tail pieces may be bent over or around any fixed object or
movable piece of machinery. The edges of the plate near the hole traversed by
the bolt are bent after the bolt head or nut is in the desired position, so as to
embrace the bolt head or nut. Thus when the plate is in position and its arm or
tail piece or arms or tail pieces is or are suitably secured rotation of the bolt or of
the nut embraced will be prevented.
To facilitate the bending of the edges of the plate to embrace the bolt head or
nut radial slits or cuts may be made therein, or the plate may be otherwise formed
for the purpose.
A single plate may be made with two or more holes so as to
secure two or more bolts or nuts from turning. In this case additional tail pieces
or arms are not required. In order to prevent keys or wedges from moving
endwise owing to vibration or from other cause I provide the following arrange-
ment as applied in the case of a railway chair. A metal plate is bent at one end
over a cheek of the chair and at the other end is bent over the thick end of the
wedge or key to which it may be secured by nailing or screwing if found desirable
but for ordinary use this extra fastening is not necessary.
Thus any tendency
of the key or wedge to move endwise will be counteracted by the further end
of the bent plate taking bearing against the chair itself or it may be against
some other fixed part. The metal instead of only partially surrounding the wedge
may entirely surround it and both ends of the metal be lapped over or nailed to
the chair or other part.

1, HENRY ARTHUR GADSDEN, of 6 Crosby Square, Bishopsgate, in the City
of London, Merchant, 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 means for securing in place (1) bolts or nuts, and
(2) keys or wedges such as are used for fastening ends of rails together or in
railway chairs and for like purposes.
.
A piece of metal such as sheet iron or soft steel of any suitable shape has formed
through it a hole or holes large enough to slip over a bolt or bolts and to form an
arm or tail piece or arms or tail pieces of any desired length for the purpose of
being nailed or otherwise secured to wood or other material, or the arm or tail
piece or arms or tail pieces may be bent over or around any fixed object or
movable piece of machinery. The edges of the plate near the hole traversed by
the bolt are bent after the bolt head or nut is in the desired position, so as to
embrace the bolt head or nut. Thus when the plate is in position and its ann or
tail piece or arms or tail pieces is or are suitably secured rotation of the bolt or of
the nut embraced will be prevented. To facilitate the bending of the edges of the
plate to embrace the bolt head or nut radial slits or cuts may-be made therein, or
the plate may be otherwise formed for the purpose. A single plate may be made
with two or more holes so as to secure two or more bolts or nuts from turning.
In this case additional tail pieces or arms are not required. In order to prevent
keys or wedges from moving endwise owing to vibration or from other cause
I provide the following arrangement as applied in the case of a railway chair.
A metal plate is bent at one end over a cheek or jaw of the chair and at the other
end is bent over the thick end of the wedge or key to which it may be secured by
nailing or screwing if found desirable but for ordinary use this extra fastening is
not necessary. Thus any tendency of the key or wedge to move endwise will be
counteracted by the further end of the bent plate taking a bearing against the
chair itself or it may be against some other fixed part. The metal instead of only
partially surrounding the wedge may entirely surround it and both ends of the
metal be lapped over or nailed to the chair or other part.
Referring to the accompanying two sheets of drawings Fig. 1 is a plan and
Fig. 2 an elevation partly in section illustrating the application of a piece of sheet
metal according to this invention for locking a nut. In Fig. 1 the nut is shown
unlocked whilst in Fig. 2 it is shown locked. Figs. 3 and 4 are similar views to
fige. 1 and 2 of a modification. Figs. 5 and 6 are elevations at right angles to each
otber illustrating the application of a single piece of sheet metal for locking two
nuts. In Fig. 5 the nuts are shown unlocked in Fig. 6 they are shown locked.
Fig. 7 is a plan of a rail, chair, and key or wedge provided with means according
to this invention for locking the said key or wedge in position. Fig. 8 is a similar
view to Fig. 7 illustrating a modification.
Referring to Figs. 1 and 2 the piece of sheet metal constituting the locking
device is cut or stamped to form with a single arm or tail piece 1 and an enlarged
part 2 through which is a hole large enough to pass over the end of the bolt 3.
The outer portion of the enlarged part notched as shewn so as to form a number
of radial projections or fingers 4 capable of being readily bent up so as to embrace

page_text: a nut 5 screwed on the bolt 3, as shewn in Fig. 2 and thereby to securely lock the
same and prevent its turning and so working loose. The arm or tail piece 1 is in
the example shown, straight and secured to the piece of timber 6 through which
the bolt passes by nails 7. In the modification shown in Figs. 3 and 4 the sheet
metal locking device has two arms or tail pieces 1 and 1* such as can be secured
as shewn to a piece of timber 6 by bending over the outer end of each arm and
nailing it. The nut 5 is locked in place by an enlarged intermediate portion 2
having projections or fingers 4 similar to those shown in Figs. 1 and 2. In the
arrangement shown in Figs. 5 and 6 the sheet metal locking device is made with
two enlarged portions 2 and 2* and an intermediate connecting part 1. Each
enlarged portion is similar in form and construction to that shown in Figs. 1 and 2.
Each nut 5 is locked by bending the projections or fingers 4 up around the nut
as before In this example the sheet metal locking device need not be secured by
nailing or screwing as in other examples. As will be evident the means above
described for locking a nut are equally applicable to bolts with square or polygonal
heads. Any desired number of fingers or projections 4 may be used-In some
cases even one may suffice.
Referring to Fig. 7 which illustrates the locking of a key or wedge in a railway
chair 8 is a portion of a rail; 9 the chair and 10 the key or wedge for holding the
rail in the chair. The key or wedge is according to this invention prevented from
moving endwise (whether owing to vibration or other cause) by means of a sheet
metal fastening device 11 which is interposed between the key or wedge and the
cheek or jaw 12 of the rail chair. One end (13) of the said sheet metal device 11
is bent round one end of the cheek or jaw 12 as shown and the other end (14) is
bent round the end of the key or wedge as shown in dotted lines after the key or
wedge has been driven home. The said end 14 of the device 11 may if desired be
secured to the key or wedge by nailing or screwing. In lieu of bending over the
end 14 after the key or wedge has been driven home as described the device 11
may be first bent at the end 14; then be driven home with the key or wedge 10
and afterwards the end 13 be bent round the end of the cheek or jaw 12 as shown
thus securing the key or wedge. In the arrangement illustrated in Fig. 8 the sheet
metal locking device surrounds the key or wedge its two ends being bent around
the one end of the cheek or jaw 12 after the key or wedge with the device 11
around it has been driven home. The said ends may be secured by a screw
as shown.
Having now particularly described and ascertained the nature of this inven-
tion and in what manner the same is to be performed, I declare that what
I claim is:
1. Devices for securing bolts and nuts to prevent their turning made of metal
substantially as hereinabove described with reference respectively to Figs. 1 and 2,
Figa 3 and 4, and Figs. 5 and 6 of the annexed drawings, or any mere modifica-
tion thereof.
2. The means substantially as described with reference respectively to Fig. 7 and
Fig. 8 of the drawings annexed for securing keys or wedges in chairs.
