IMPROVEMENT IN AND CONNECTED WITH LAMPS AND THEIR REFLECTORS
Year: 1884

page_text: I HENRY SALSBURY of 125 and 126. Long Acre in the county of Middlesex
Lamp Manufacturer do hereby declare the nature of my said Invention for AN
IMPROVEMENT IN AND CONNECTED WITH LAMPS AND THEIR REFLECTORS, to be as
follows:-
The object of this invention is, to so construct or arrange the back portion of a
lamp, that the reflector. can be drawn out partially to admit of the wick being
lighted from the back without removing the lamp from the position it occupies
or to be drawn wholly out and detached for cleansing or other purposes, a spring
being fitted to fix the reflector temporarilly in either the half open or in the closed
positions.
For the purpose of my invention I form two ribs on or channels in the back of
the lamp one channel being above and one below an aperture therein of about
the size or diameter of the reflector proper.
ㄓ
From a slotted hole in the back I arrange the end of a spring which serves to
lock the reflector in either of the positions already mentioned.
The reflector is preferably dished and is in a piece with a shutter which slides
in the channels and the bottom edge has an angle notch or recess at or about the
middle of its width and another notch near one edge into which the spring can
engage.
The middle notch or recess is chamfered or inclined on one side only to facilitate
the reflector being pushed in, but the spring must be depressed to release it from
either notch.
For head lamps of Bicycles and for side; lamps of Tricycles or other vehicles
I bridge or span the strap over the reflector but for carriage, railway, hand or
other lamps or lanterns the bridge or span will not be necessary.
Dated this Second day of January 1884.

page_text: I HENRY SALSBURY of 125 and 126 Long Acre in the county of Middlesex,
Lamp Manufacturer, do hereby declare the nature of my said invention for :-" AN
IMPROVEMENT IN AND CONNECTED WITH LAMPS AND THEIR REFLECTORS," and in
what manner the same is to be performed, to be particularly described and
ascertained in and by the following statement:—
The object of this invention is to so construct or arrange the back portion of a
lamp, that the reflector can be drawn out partially to admit of the wick being
lighted from the back without removing the lamp from the position it occupies
said reflector can however be drawn wholly out and detached for cleaning or other
purposes, a spring being fitted to fix the reflector temporarilly in either the half
open or in the closed position.
For the purpose of my invention I form two ribs on or channels A B in the
back C of the lamp as seen in Figures 1 and 2 of the annexed drawings one
channel being above and one below an aperture D therein of about the size or
diameter of the reflector proper E. From a slotted hole F in the back C I arrange
the end of a spring G which serves to lock the reflector E in either of the positions
already mentioned. The reflector E is preferably dished and is in a piece with a
shutter H which slides in the channels A B, and the bottom edge I has an angle
notch or recess J at or about the middle of its width and another notch K near
one edge as at Figure 3 into which the spring G can engage.
The middle notch or recess J is chamfered or inclined on one side only to
facilitate the reflector E being pushed in, but the spring G must be depressed to
release it from either notch.
For head lamps of bicycles and for side lamps of tricycles or other vehicles
I bridge or span the strap L over the reflector E but for carriage, see Figure 4,
railway, band, see Figure 5 or other lamps or lanterns, the bridge or span will not
be necessary.
Any roughened or punctured surface such as at M can be arranged for striking
matches on to obtain a light.
The draw out reflector or the combined reflector and shutter before mentioned
and shown, as I prefer to arrange it with the notched edge for the spring.
adjustment, is applicable to the lamps described in my previous patents No³ 503
and 5562 of the year 1882 but I do not limit myself to fitting such a moveable or
removeable reflector to any particular form or kind of lamp; the invention being
of such a character that by slight modifications it can be adapted to any lamp
having its burner enclosed in a casing in or to which a reflector is fitted.
It will be seen by the drawings that my invention is distinct from a fold up,
a hinged, a pivotted, a swung, or other method of fitting reflectors and it embraces
many advantages over all known methods, notably. The facility of opening the
back to any desired distance without risk of the reflector being accidentally
withdrawn altogether and the certainty of its fixture when pushed in.

page_text: Having now particularly described and ascertained the nature of my said
invention, and in what manner the same is to be performed, I declare that what
I claim is,
A sliding reflector, or shutter and reflector, capable of adjustment in the back of
a lamp by a spring and of being locked by said spring, the adjustment notch of the
reflector having one edge inclined as and for the purpose explained the whole
arranged substantially as shown in the annexed drawings.
