Improvements in Means for Securing Lamps to Velocipedes and .
other Vehicles.
We, THERESA ELIZA BOLTON of Bolton House, Yeadon, Spinster, and EDMUND
GILYARD of Barkerend Road, Bradford, Machinist, both of the County of York,
do hereby declare the nature of this invention to be as follows:-
It consists in improvements which are applicable in the first instance to velocipede
lamps, but which may be applied to the lamps of other vehicles, such as locomotivo
lamps for railways &c.
The common method of attaching lamps to vehicles is by means of a pin and socket,
the pin usually being attached to the vehicle and the socket to the lamp, but sometimes
the positions are reversed.
But this method of attachment is liable to a serious objection in as much as that the
attachment is rapidly loosened by wear and tear, and the lamps in use shake to such
a degree as to seriously detract from their value as light producers. To obviate
this defect is the object of our invention and we accomplish this in the following
manner :-
We form the top of the pin with a hole or other suitable device for enabling us to
attach thereto a short rod of metal of suitable formn, the lower end of this short rod is
formed into a hook or other suitable device for attaching to the top of the pin and
the upper end is passed through a cap or bridge so formed as to press upon the top of
the lamp socket, and tapped or otherwise formed with a screw thread upon which is
screwed a suitable screw nut, which is tightened until the bridge presses upon the
lamp socket with sufficient firmness to prevent it from shaking. Or, instead of being
formed with a screw thread and nut, the upper end of the short rod may he formed
with a perpendicular slot and tightened by means of a suitable wedge.
Or, we may form the top of the pin with a longitudinal slot and tighten it by means
of a wedge, or form it with a screw thread and tighten by means of a nut, or in any
other suitable manner, without the use of the cap or bridge, which is however in
many cases essential.

Improvements in Means for Securing Lamps to Velocipedes and
other Vehicles.
We, THERESA ELIZA BOLTON of Bolton House, Yeadon Spinster, and EDMUND
GILYARD of 76 Barkerend Road Bradford Machinist, both in the County of York,
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
It consists in improvements which are applicable in the first instance to velocipede
lamps, but which may be applied to the lainps of other vehicles, such as locomotive
lamps for railways &c.
The common method of attaching lamps to vehicles is by means of a pin and socket,
the pin usually being attached to the vehicle, and the socket to the lamp, although
sometimes their positions are reversed.
But this method of attachment is liable to a serious objection, inasmuch as that the
attachment is rapidly loosened by wear, and tear, and the lamps in use, shake to such
a degree as to seriously detract from their value as light producers, or shake off and
get lost altogether.
To obviate this defect is the object of our invention and we accomplish it in the
following manner :-
We form the top of the pin with a hole or other suitable device for enabling us to
attach thereto, a short rod of metal of suitable form, the lower end of which is formed
into a hook or other suitable device for attaching to the top of the pin, and the upper
end of which is in use passed through a cap or bridge, so formed as to press upon the
top of the lamp socket; and is tapped or otherwise formed with a screw thread upon
which is screwed a suitable screw nut; or is formed with a perpendicular slot;
through which is passed a suitable wedge; and by means of the screw nut or wedge
as the case may be, the cap or bridge is pressed tightly down upon the lamp socket
with sufficient firmness to prevent it from shaking. Or, in some cases where a bridge
is not essential, we form the top of the pin with a longitudinal slot, or provide it with
a screw thread, and so by means of a wedge or screw nut tighten it to the requisite
firmness.
In order that the foregoing may be better understood we send herewith a sheet of
Drawings in which :-
Fig. 1 shows a side view of a lamp steadied by our improvements a is the short rod,
formed with a hook a² which is passed through an aperture in the top of the pin b.
The upper end of rod a is formed into a screw thread a on which works the
screw nut at which presses the bridge c firmly down upon the socket d.
Fig. 2 shows the back of the lamp socket d and the rod a in this case the bridge c
is tightened by the wedge e Fig. 3 & 4 show respectively the methods of tightening
the lamp socket d by means of a screw. nut or wedge without the use of a bridge.

page_text: Having now particularly described and ascertained the nature of our said inven-
tion, and in what manner the same is to be performed, we declare that what we
claim is
1st. The combination with a lamp pin of a bridge pressing upon the lamp socket
and tightened by means of a short rod and nut or rod and wedge substantially as
described and shown hereinbefore and in the accompanying drawing, for the purpose
set forth.
2nd. A lamp pin so formed that a screw nut or a wedge may be employed for
pressing upon the lamp socket and so steadying the same, substantially as described
and shown hereinbefore and in the accompanying drawing.
