Improvements in and relating to Pocket Lamps.
We, WILLIAM TRABUE, Inventor, JOHN BACON HUTCHINGS, Dealer, and
MARK MCKNIGHT, Draughtsman, citizens of the United States of America,
residing respectively at 2219 Brook Street, 1 Hutchings Place and 232 Secon
Street, Louisville, Jefferson County, State of Kentucky, one of the United States
of America, 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:-
Figure 1 is a central longitudinal section of a lamp or lighter according to this
invention, in extinguished position.
Figure 2 is a similar section of the lamp in lighted position.
Figure 3 is a side view of Figure 2.
Figure 4 is a section in the position of Figure 2, the construction slightly
modified.
Figure 5 is a section on line 5-5 Figure 1.
Figure 6 is a broken detail plan or diagram of igniting device.
Figure 7 is a broken horizontal section of the pellet chamber and plunger.
The lamp body is made in tubular form, preferably of metal. The tube A has
an end plug B, secured in usual manner, a wick and oil chamber C, a partition D
through which the wick passes, a notch E which is open when access is had to the
lamp as for lighting a cigar, a partition F with a small hole therein, through which
one igniting pellet may pass at a time, and a pellet chamber G in which the igniting
pills or pellets are stored.
In the modification, Figure 4, the tubular body has in addition a side opening H,
and a closing end 1, and a non-conducting wad K is attached to partition F, by a
rivet or otherwise.
The tube A has an opening M through which the debris of an exploded pellet
may fall, and an igniter O, having spring arms and roughened surfaces between
which pellets are fed, in igniting. This igniter is preferably attached at its central
part to the partition D, with its arms extending toward the pellet chamber, as
indicated in Figures 1 and 2.
The outer casing P is tubular and surrounds tube A for part of its length. The
tube P has a notch Q, which may be brought in register with notch E, and a small
spring R, lying in a groove between the two parts of the frame, limits the longi-
tudinal movement of the tubes and prevents rotation. A hole W in the bottom of
tube P may be brought into or out of register with the hole M in tube A.
Tube P is closed at the end except for an end opening S provided with a cover T,
and a small tube U extends inward from the end of the tube. A spiral spring V
is interposed between the closed end of the tube P and the end of the tube A, and
closes the notches in the tubes by throwing them out of register.
In the modification, Figure 4, tube P¹ has one end closed, and has a hole X
which may be brought into register with hole H in tube A.
The chamber C may be filled with oil or other combustible, and provided with a
wick d. The chamber G may be charged with a large number of small globular
ignition or percussion pellets, which may be fed in through stopper T, in Figure 1,
or through holes X, H, Figure 4, according to construction.
The partition F has a small hole therein, large enough to pass a single pellet.
and a light spring a lies in front of this hole, to prevent the escape of a pellet
unless pushed through the hole.

page_text: The plunger is attached to the tube P, and extends inside chamber G, so that
when the tubes are pressed apart, as in Figure 1, there is just room for a pellet
between the end of plunger c and spring a.
The position of Figure 1 is the normal position of the lamp, the large notches
being out of register, and the wick chamber being thus closed. It is not very
material whether the openings M, W, are then in register or not. When in the
position of Figure 1, if the tube A be quickly pressed into tube P, the pellet in
front of the plunger c will be forced through the opening in partition F, by said
plunger, the light spring a yielding for the purpose. The plunger forces the pellet
between the roughened surfaces of spring arms O, and ignites it just under the end
of wick d, thus lighting the wick. The same movement telescopes the tubes A
and P and brings the notches E and Q into register, so that the flame of the wick
may be exposed, as for lighting a cigar. The debris from the pellet will fall out
when the lamp is open or closed, according to the arrangement of the holes M. W.
On releasing the pressure on the ends of the tubes the notches E and Q will
move out of register, and the lamp will be extinguished for lack of air.
It will be readily understood by persons skilled in this art that other modifications
may be made without departing from the spirit of this invention.
Having now particularly described and ascertained the nature of our said
invention and in what manner the same is to be performed we declare that what
we claim is.
1. The combination of the tube containing the lamp body, and having a side
notch, and the tube telescoping therewith and also having a side notch to be brought
in register with the notch in the body tube, a spring interposed between the tubes
and tending to hold them extended, and the pellet chamber in one of the tubes having
a plunger to convey a pellet toward the lamp wick, all substantially as described.
2. The pocket lamp consisting essentially of the two telescopic tubes having
chambers and notches substantially as described, the plunger operating to expel a
single pellet from its chamber, and the spring igniter having roughened surfaces
nearly in front of the pellet chamber and in proximity to the lamp wick, all
combined substantially as described.
3. In a pocket lamp, the telescopic tubes provided with chambers and notches
substantially as described, the plunger operating through the pellet chamber and
through the small opening in the end thereof, and the light spring arranged to
prevent the escape of the pellets except when propelled by the plunger, all combined
substantially as described.'
4. The novel features of invention in a pocket lamp, substantially as hereinbefore
described.
