page_text: LETTERS PATENT to Henry Salsbury, of the firm of "J. E. Salsbury," of 125
& 126, Long Acre, in the County of Middlesex, Carriage Lamp Manufacturer,
for an Invention of "IMPROVEMENTS IN OR APPLICABLE TO HANGING LAMPS
FOR BICYCLES AND SUCH LIKE PURPOSES."
PROVISIONAL SPECIFICATION left by the said Henry Salsbury at the Office
of the Commissioners of Patents on the 27th January 1880.
HENRY SALSBURY, of the Firm of "J. E. Salsbury," of 125 & 126, Long Acre,
" IMPROVEMENTS IN
in the County of Middlesex, Carriage Lamp Manufacturer.
OR APPLICABLE TO HANGING LAMPS FOR BICYCLES AND SUCH LIKE PURPOSES."
This Invention relates to certain improvements in or applicable to hanging lamps
for bicycles, tricycles, and such like purposes where the lamp is to be hung upon a
running axle or shaft, the object being to provide a socket piece which is in two
parts, hinged together and opening as a pair of jaws, that will be perfectly secure
from becoming detached or unhung from the axle or bar upon which it is suspended,
and all rattle or shake of the parts is provided against, and also provision is made
for retaining the oil reservoir within the lamp in case of the door of the lamp being
accidentally left unfastened.
The divided socket is made with the hinge at the back part thereof opposite to
the opening of the jaws, and a spring, either a spiral "mouse trap" spring, or
preferably a flat spring, is attached to the hinged parts, so that the socket jaws will
be held apart when the lamp is unhung, or when the securing device is not in
action to hold the parts together. The leather bearings in the ends of the socket
piece which rest upon the supporting shaft are in two halves, and by the horizontal
position of the hinge and of the opening the undivided surface of the leather edge
will be brought to bear upon the shaft, thus preventing wear of the leathers.
The said sockets are carried upon suspension wires secured on the back of the
lamp, which wires are either carried over towards the front or are bent at the
upper part to form at once a spring tongue piece and two vertical guides, for
purpose to be described.
In the case of the curved wires the upper half of the socket may fit into and be
soldered into the loop thus formed, and in the other case one half of the socket will
be provided with vertical slide tubes to slide upon the suspension wires.

page_text: In the first of these two cases the fastening of the socket piece may be (1)
by vertical sliding bolt or screw secured on the back of the socket on one half of
the same, and acting when depressed upon a projecting shoulder upon the lower
half of the socket piece; (2) by a lever piece attached to the lower half of the
socket, and capable of latching with a hook on the back of the body of the lamp;
or (3) by the mouse-trap spring the two halves of the socket will be held together
closely, and upon applying the said socket to the suspending shaft a thumb piece
upon the lower half of the socket will be operated to open the jaws of the said
socket to pass onto the shaft.
In the second of the two cases the socket piece is carried upon two guide tubes
sliding on the suspension rods, and the top of the said rods will act to secure the
perfect closing of the parts of the socket, (1) by being curved over and springing
upon the outer half of the said socket, which will hold the two parts firmly
together; or (2) by the tongue piece bearing against a projecting shoulder piece
formed upon the lower half of the socket piece, and in this case the guide tubes will
be secured upon the upper half of the socket piece, and in both these fittings the
weight of the lamp tends to and assists in the closing of the socket.
For securing the lamp reservoir in case of non closing of the lamp door the spring
clip or catch provided at the bottom of the lamp for fastening the said door is made
so as to project upwards and so retain the lamp reservoir in position and from falling
out, even when the door is not closed.

the said Henry Salsbury in the Great Seal Patent Office on the 27th July
1880.
HENRY SALSBURY, of the Firm of "J. E. Salsbury," of 125 & 126, Long Acre,
in the County of Middlesex, Carriage Lamp Manufacturer. " IMPROVEMENTS IN
OR APPLICABLE TO HANGING LAMPS FOR BICYCLES AND SUCH LIKE PURPOSES."
This Invention relates to certain improvements in or applicable to hanging lamps
for bicycles, tricycles, and such like purposes where the lamp or article to which
the socketed fastening is applied is to be hung upon an axle or shaft, the object
being to provide a socket piece, hinged together and opening as a pair of jaws, that
will be perfectly secure from becoming detached or unhung from the axle or bar
upon which it is suspended, and all rattle or shake of the parts is provided against,
and also in the case of the lamp provision is made for retaining the oil reservoir
within the lamp in case of the door of the lamp being accidentally left unfastened.
The divided socket is made with the hinge at the back part thereof opposite to
the opening of the jaws, and a spring, either a spiral "mouse trap" spring, or
preferably a flat spring, is attached to the hinged parts, so that the socket jaws will
be held apart when the lamp is unhung or when the securing device is not in action
to hold the parts together.
In order that the said Invention may be well understood I have hereunto
annexed a Sheet of Drawings, and will refer to the same by. Figures and letters in
the following particular description:-
Fig. 1 is side view, Fig. 2 a back view, and Fig. 3 side view, with door and
hinged socket open, of lamp constructed according to this Invention. A are the
suspension wires, which are carried down the back and under the bottom of the
lamp case for purpose of strength, and said wires A. are curved over at tops A¹, and
the top half of the socket B is rigidly secured (soldered) into the loop formed by
the wires at A'; C, the vertically sliding bolt for fastening of the socket piece after
adjustment to the bar upon which the lamp is hung, said sliding bolt C being
secured by and sliding in the guide D on the socket, and the point of said sliding
bolt C acts when depressed upon the projecting shoulder E upon the lower half of
the socket piece to hold the jaws of same closed when adjusted in position. A
spring of the kind hereinafter specified is provided on the back of the socket to keep
the jaws thereof apart when same is not locked in position.
Figs. 4 and 4* are detached side views of this socket piece respectively closed
and open, said Fig. 4* representing the position apart of the jaws so held by the
spring.
In Figs. 5 and 5* a screw C¹ is employed for securing the jaws of the socket piece
together instead of the sliding bolt C; a is the spring of flat band steel held in
sockets or loops upon the upper and lower halves or jaws of the socket piece.
In Figs. 6, 6, 6b, and 6° a wire lever piece E¹ is applied upon the lower jaw of
the socket piece, the outer free arm whereof will, when closed, engage (by springing)
in a catch to be provided upon the back of the lamp. Fig. 6' represents in section
the jaws of the socket piece with a spring band piece al soldered at b to the inside
of one jaw, and acting upon the other jaw by the nose of said spring to hold the
jaws open ready for being placed upon the axle or rod upon which the lamp is to
be suspended. When placed in position the arm of lever piece El will be pressed
down in position, as shown in Figs. 6ª, 6, and 6°, to secure tightly or securely the
lamp or other article carrying the fastening upon the rod whereon it is to hang. In
Fig. 6° the door of the lamp is shown hinged at the bottom, so that in adjusting the
lamp to the hub of a bicycle, for instance, the said lamp will, by leaving the door
open, be narrower for introduction of same between the spokes of the wheel.
Figs. 7 and 7 represent the application of the "mouse trap" spring, the lower half

page_text: of the socket being shown provided with a nose or thump piece for facility of
holding the jaws apart when lamp or article to which the said socket is attached is
being placed in position.
When the socket piece B is not secured in the top loops A' of the suspension wires
A one half of said socket piece will be provided with vertical slide tubes F to slide
upon the said suspension wires, and the top of the said rods will act to secure the
perfect closing of the jaws or parts of the socket (1) by the curved portion A* of
the suspension wires, as shown in Figs. 11 and 11, wherein the said suspension
wires are formed of one piece, the part A2 being bent across, as shown, to form a
spring into which the front jaw B¹ of the socket will be pressed after application of
the lamp to the rod upon which it is to hang suspended; Fig. 11* represents this in
front view.
In Figs. 8, 9, and 10, being respectively side view of lamp with socket jaws closed,
like view with jaws open, and back view with jaws closed, the suspension wire is
formed as a spring tongue piece A³, which will bear against the projecting shoulder
piece E formed upon the lower half of the socket piece, and in this case the guide
tubes F are secured upon the upper half of the socket piece, and in both these
fittings the weight of the lamp tends to and assists in the closing of the socket.
For securing the lamp reservoir from falling out in case of non closing of the
lamp door the spring clip or catch G is provided at the bottom of the lamp for
fastening the said door and made with a long nose, as shown, so as to provide a
considerable projection upwards at the inner end of the said nose, and so retain the
lamp reservoir in position and from falling out, even when the door is open.
Having now described the nature and particulars of the said Invention, I claim,―
The improvements in or applicable to hanging lamp, suspension and securing
apparatus for bicycles, and such like or analogous purposes, consisting of the parts
herein specified and described in reference to Figs. 1, 2, 3, 4, and 4; 5 and 5*; 6, 6,
6b, and 6; 7 and 7*; 8, 9, and 10, and 11 and 11* of the accompanying Drawings.
In witness whereof, I, the said Henry Salsbury, have hereunto set my hand
and seal, this Twenty sixth day of July, in the year of our Lord One
thousand eight hundred and eighty.
