Improvements in or relating to Lamps and in Fittings Connected
therewith.
I, HENRY SALSBURY, of 19 Mercers Road, Upper Holloway, Middlesex, Lamp
Manufacturer do hereby declare the nature of this invention to be as follows:-
This invention relates to certain detail improvements in lamps and consists, First.
In making conical or semispherical joints with leather lining pieces to that part of
the lamp used with cycles by which it is supported or suspended from a stem or other
part of the machine the conical or semispherical joint portion with leather lining
being used in conjunction with parallel links connected by pins in pairs and the joints
be held rigidly or in close contact by bow or other shaped springs either acting upon
the nuts or heads of the pins or encircling the pins to obtain the necessary degree of
friction of one part of the joint to the other with the leather lining between.
In addition to the springs before mentioned I employ a compensating spring,
preferably of coiled form, having one end secured to the lamp body or back strap and
the other end to one of the links so that any vibration or tremulous motion of the
machine while travelling is absorbed by the compensating spring instead of being
imparted to the lamp, the lamp being thereby kept free from vibration, oscillation, or
jumping, a steady flame in the lamp being the result.
My next improvement consists of an eye or socket piece through which a screw
pin can be inserted and made to bite the extension axle of a Rear Driving Safety
Bicycle, said socket piece having a vertical stem, serving as a bracket for carrying the
lamp, said socket with pinch screw and vertical stem piece may be part and parcel."
a lamp and instead of affixing said appliance to the extension of a Rear Driving
Safety Bicycle, it may be attached to the handle bar or to any other suitable part of
the machine particularly if said socket pinch nut and stem be used in connection with
the appliances referred to in the first part of the Specification.
My next improvement relates to a novel construction or arrangement of single
plate tongue or catch fastener for securing the doors of lamps, said tongue or single

page_text: plate fastener being applicable to Carriage Lamps, generally, Cycle Lamps, and also
to other Lamps in which a door has a folding or swing action.
This part of the invention consists of a single plate of springy material bent curved
and set to shape with a rounded or angle nose piece and with two notches in the side
edges, so that the part of the tongue between the edge and the notches is of greater
width, so that the edge of the door which is also notched can by riding under pressure
on the side portions of the tongue compress the tongue or force it downwards and
when the door is closed to the edge escapes from the tongue, so that the reduced
portion of the tongue, where the notches are, springs up into the notch of the door
and holds it perfectly secure, the lips of the notches in the tongue pressing against
the outside of the door for that purpose.
Instead of the side notches the tongue may be recessed, grooved, or otherwise be
made to engage in or to receive some portion of the door, or the door may be
prepared to fasten itself to the tongue when closed to.

Improvements in or relating to Lamps and in Fittings Connected
therewith.
I, HENRY SALSBURY, of 19 Mercers Road. Upper Holloway, Middlesex, Lamp
Manufacturer, 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 certain detail improvements in lamps and consists, First,
In making conical or semispherical joints A (see Figures 1. 2 and 3 of the annexed
drawings) with leather lining pieces B to that part of the lamp C used with Cycles by
which it is supported or suspended from a stem or other part of the machine, the
conical or semispherical joint portion A with leath lining pieces B being used in
conjunction with parallel links D connected by pins E in pairs and the joints be held
rigidly or in close contact by bow or other shaped springs F either acting upon the
nuts or heads G of the pins E or encircling the pins E to obtain the necessary
degree of friction of one part of the joint to the other with the leather lining
between.
In addition to the springs before mentioned, I employ a compensating spring H
preferably of coiled form, having one end secured to the lamp body or back strap and
the other end to one of the links D, so that any vibration or tremulous motion of the
machine while travelling is absorbed by the compensating spring H instead of being
imparted to the lamp C, the lamp being thereby kept free from vibration, oscillation,
or jumping, a steady flame in the lamp being the result.
Aly next improvement consists of an eye or socket piece, see Figure 4, through
which a screw pin I can be inserted and made to bite the extension axle of a Rear
Driving Safety Bicycle, said socket piece having a vertical stem J serving as a bracket
for carrying the lamp, said socket with pinch screw I may be part and parcel of a
lamp, see Figure 5, and instead of affixing said appliance to the extension of a Rear
Driving Safety Bicycle, it may be attached to the handle bar or to any other suitable
part of the machine particularly if said socket pinch nut and stem be used in
connection with the appliances referred to in the first part of the Specification.
My next improvement relates to a novel construction or arrangement of single
plate tongue or catch fastener K, see Figures 1, 3 and 6, for securing the doors L of
lamps, said tongue or single plate fastener being applicable to Carriage lamps
generally Cycle lamps and also to other lamps in which a door has a folding or swing
action.
This part of the invention consists of a single plate K of springy material bent,
curved and set to shape with a rounded or angle nose piece M and with two
notches N, N, in the side edges, the part of the tongue between the edge and the
notches being of greater width, so that the edge of the door, which is also notched,
can by riding, unler pressure, on the side portions of the tongue, compress the tongue

page_text: or force it downwards and when the door is closed to, the edge escapes from the tongue,
so that the reduced portion of the tongue where the notches are, springs up into the
notch of the door and holds it perfectly secure, the lips of the notches in the tongue
pressing against the outside of the door for that purpose.
Instead of the side notches, the tongue may be recessed, grooved, or otherwise be
made to engage in or to receive some portion of the door, or the door may be prepared
to fasten itself to the tongue when closed to.
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. The improvements in lamps described with reference to Figures 1, 2, and 3 of the
annexed drawings, consisting of conical or equivalent shaped joints A, intervening
leather washers B, used with parallel links D in pairs as described.
2. The bow or equivalent shaped tension spring F connecting the two pins E of
each pair of links D on one or on both sides of the suspension appliance of a Cycle
lamp as and for the purpose set forth.
3. The compensating spring H coiled on one pin of the suspension apparatus
and connected to one link and to the body of the Cycle lamp as set forth.
4. The employment of an eye or socket piece, Figure 4, provided with a stem J for
carrying a lamp and the means of attaching it to an extension axle of a Rear Driving
Safety Bicycle or without the stem J when affixed as part of a Cycle lamp as
described.
5. The single plate tongue or catch fastener K of the form shown at Figure 6 and
its employment to secure the door of a cycle lamp or the door of a Carriage lamp as
herein before set forth.
