Improvements in connection with Hand Signal and other Lamps.
We ARTHUR VICKERS LINLEY of the Firm of Linley & Co., Lamp Manufacturer,
and WALTER HENRY OWENSMITH, Works Manager, both of Bourne Works 73 Great
Lister Street, Birmingham, in the County of Warwickshire, do hereby declare the
nature of this invention to be as follows:
The main object of this invention is to provide an improved hand signal lamp,
for petroleum or other oil, with removable coloured glasses, which can be operated
by the hand which carries it. For the purpose of this invention, the oil reservoir is
surrounded at its top and sides by a metal shell or cover, a space being left between
the outer surface of the oil reservoir and the inner surface of such shell or cover.
This shell or cover has a hole in its top and an annular metal band is attached to
it surrounding this hole. The burner fits into the top of the oil reservoir within
the annular metal band. The bottom of the lamp is perforated so that when the oil
reservoir is in position, the air which enters through such perforation may pass up
the annular space between the outer shell or cover and the oil reservoir, and
conducted by the metal band may ascend in a tubular stream around the burner.
This arrangement of reservoir, shell, band, and perforation is also applicable to other
kinds of lamps.
The lamp is provided with an inside case or body as usual, which is free to move
within the outside case or body unless held by a catch. The catch in this lamp is
actuated by a push or pull rod, preferably the latter, which is so shaped at its top
end that it can be conveniently grasped by one or more fingers of the hand which
carries the lamp, when the lamp is being carried by its top handle. The catch itself
is attached to the inside body so as to move freely within certain limits, and may
be made as a sliding bolt or as a pivoted crank-or bolt & crank combined-and
may engage in, holes or notches, or be engaged by, studs or projections, in or upon
the outer case or body; it may be "locked" by a spring or by the action of gravity,
and may be released from its "locked" position by means of the push or pull rod
above mentioned. In operating the lamp, the rod is moved by the fingers as
aforesaid, releasing the catch, and the handle is twirled around and then checked by
the hand; the result being that the momentum imparted causes the outside body to
rotate around the inside body, till the catch-now released by the fingers-engages
and checks it at the position required.
It is thus possible to quickly cause the lamp to show white red or green by the
use of one hand.
The coloured glasses fitted to the inside body are held at their sides by metal strips
or clips in the usual way, and are kept in place by a ring which fits into an annular groove,
recess, or swage at or near the bottom edge of the inside body; this ring projects
from such groove sufficiently to form a shelf or ledge upon which the bottom edges
of the coloured glasses may rest. This ring does not form a complete circle but is so

page_text: made that the ends can be sprung together to release it from, or to replace it in, the
annular groove aforesaid. A ready and effective means of replacing broken glasses
is thus provided.

COMPLETE DIMOITICATION
Improvements in connection with Hand Signal and other Lamps.
We ARTHUR VICKERS LINLEY of the Firm of Linley & Co., Lamp Manufacturer,
and WALTER HENRY OWENSMITH Works Manager, both of Bourne Works 73 Great
Lister Street, Birmingham in the County of Warwickshire 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:-
The main object of this invention is to provide an improved hand signal lamp-for
petroleum or other oil, and with removable coloured glasses-which can be operated
by the hand which carries it.
For the purpose of this invention-when petroleum is required to be burned-the
oil reservoir V is surrounded at its top and sides by a metal shell or cover U, a space Q
being left between the outer surface of the oil reservoir V, and the inner surface of
this shell or cover U: this shell or cover U has a hole W in its top, and an annular
metal band R is attached to it surrounding this hole: the burner S fits into the top
of the oil reservoir V within the annular metal band R. The bottom of the lamp is
perforated T so that when the oil reservoir V is in position, the air which enters
through such perforation T may pass up the annular space between the outer shell
or cover U and the oil reservoir V, and conducted by the annular metal band R,
may ascend in a tubular stream around the burner S. This arrangement of oil
reservoir, shell, band, and perforation is also applicable to other kinds of lamps.
For the purpose of operating the lamp with one hand the lamp is provided with
an inside case or body, as usual, which is free to move within its outer case or body,
unless held by a catch. The catch shown in the annexed drawing is actuated by a
push rod E, which may be depressed by the thumb of the hand carrying the lamp,
when the lamp is being carried by its top handle. This push rod E terminates at
its upper extremity in a suitable button or thumb piece C; and its lower extremity I
is attached to one arm of a crank F which is pivoted at K; the other arm of
this crank F engages a portion of the catch G the peg J of which protrudes
through the inside body sufficiently to engage in an appropriate hole recess or
notch in the outside case or body. The catch G is fastened to a spring H which
retains it in its locking position; the spring H being fastened to part of the inside
body, as at L. The push rod E slides up and down in the tube D. Thus, if C is
depressed, the crank F making a partial rotation about the pivot K, pushes back the
catch G releasing the peg J from its hole recess or notch in the outside case or
body whilst in this position the handle is twirled around, the thumb pressure
removed and the twirling movement checked by the hand, the result being that the
momentum imparted causes the outside body to rotate around the inside body, till
the catch engages and checks it at the position required. It is thus possible to show
white red or green by the use of one hand. This catch may be made as a sliding
bolt, with or without a similar crank to the one shewn-and it may be actuated by
either a depressing or lifting rod, and be locked either by a spring or by the action
of gravity and may engage in holes recesses or notches, or be engaged by studs or

page_text: projections in or upon the outer case or body: or the lifting rod may be extended
so as to reach the bottom of the lamp and engage therein, thus dispensing with the
crank.
The coloured glasses N fitted to the inside body are held at their sides by metal
clips or strips M M in the usual way, and are kept in place by a ring O which fits
into an annular groove recess or swage, at or near the bottom edge of the inside
body: this ring projects from such groove sufficiently to form a shelf or ledge upon
which the bottom edges of the coloured glasses may rest. This ring does not form
a complete circle but is so made that the ends P can be, sprung together to release
it from or to replace it in, the annular groove aforesaid. A ready and effective means
of replacing broken glasses is thus provided.
Having now stated the purpose and method of our invention what we claim is:-
1. The combination of reservoir, shell, band, & perforation in connection with the
lamp as herein described.
2. The method of locking the lamp by a catch released in the manner herein
described.
3. The method of holding in the curved coloured glasses N by the retaining ring 0.
in conjunction with the annular swage or recess in the inside body as herein
described.
