POCKET- LAM P.

SPECIFICATION forming part of Letters Patent No. 451,301, dated April 28, 1891.

Application iiled December 13, 1890. Serial No. 374,536l (No model.)

To all whom it may concern,.-

Be it known that I, JOHN HARVEY FARREL, a citizen of the United States, residing at Camden, in the county of Oamden and State of New Jersey, have invented certain new and useful Improvements in Pocket-Lam ps, of which the following is a specifica-tion.

My invention relates to that class of lighting devices designated as pocket-lamps proto vided with means for feeding and exploding by contact with a device a fulminating pellet, cap, or ignitible material.

My invention consists of a lamp of the construction and having the parts and devices I5 arranged for operation substantially in the manner hereinafter described, and particularly as pointed out in the claims.

The nature of the invention and the characteristic features thereof will be more fully zo understood from the accompanying drawing,

forming part hereof, which represents in perspective a pocket-lamp embodying the features of my invention, with the divided housing, oil-receptacle, and part-s thereof exposed to view.

Referring now to the drawing, the exterior housing of the lamp is divided and is composed of two members A and A', connected together by means of a hinge d.

A2 is an exterior lid or cover attached to one of these members by a hinge a', and adapted to close the upper portion of the housing and extinguish the lamp. In the drawing the lid A2 is represented as hinged 3 5 to the member A; but, if preferred, it may be hinged to the member A. The lid A2 is retained in a closed position by means of a spring-catch a? of any preferred construction.

A3 is a receptacle adapted to receive oil or 4o an absorbent material or substance saturated with oil. This receptacle A3 is connected with or attached to one of the members A or A. In the drawing it is represented as attached to the member A; but, if preferred, it

may be attached to or connected with the member A.

A4 is an interior cover or lid mounted in or on or attached to the oil-receptacle A3 in any suitable manner-for example by means of a hinge CL4- and adapted to be opened in order to iill the same. This cover A4 is provided with an aperture a5, adapted to permit of the passage of one extremity of the wick from the interior of the receptacle A3 through the lid or cover A4, so that when the latter is closed the extremity of the Wick a: occupies a position adjacent to the point at which the fulminating pellets, drops, orbits of ignitible material are exploded.

a6 is a lug or latch-pin attached to the mem- 6o ber A2 and adapted to penetrate an aperture of, formed between the Wall of the receptacle A3 and the member of the housing A, and engagingin a slot d8, formed in the 'interior lid or cover A4 of said receptacle, and adapted 65 to retain the latter in a closed position when the member A of the housing is closed.

`b is a retaining pin or lug, preferably secured to the Wall a9 of the oil-receptacle A3.

c is' a stud pin or support provided with a 7o loose sleeve c', located in proximity to the exposed end x of the wick when the interior lid or cover A4 is in its normal or closed position.

d is a toothed disk mounted on a pin CZ and arranged so that a portion of its periphery projects through a slot formed in the wall of the housing` and extending outside thereof. The pin d of the disk d is bifurcated for a purpose to be presently described.

e is a spring having one extremity thereof in engagement with the lid A2 in order to maintain the latter normally in an open position, and having the other extremity thereof in contact With the toothed disk d in order to prevent said disk from being turned in a reverse direction. This spring e is preferably composed of a continuous strip of metal and is secured in place by being fitted into a recess e,'formed in a fixed lng e2, and caused 9o to engage with one of the internal corners of the housing, as at e3.

e4 is a bend or curve formed in the springmetal strip c at the point Where it engages in the recess e of the lug e2 in order to pre- 95 vent vertical displacement thereof. It may be remarked that this arrangement of the spring e not only affords a simple, efficient, and convenient means for the 'purposes mentioned, but also presents a .device having imro: portant resilient effects in action.

fis a scratcher or ignitor of any suitable construction-such, for example, as a coil of wire-having one extremityf in contact with the support c or sleeve c and thev other extremity f2 attached to the lid or covering A4 of the oil-receptacle in any suitable manner. For instance, as shown, the extremity f2 of the springf is bent so as to form a shankf3 and is attached to the cover A4 by means of loops f5 and f6, struck up or otherwise formed therein. These loops f5 and f6 are disposed at an angle to each other, so that thescratcher or ignitor fis firmly secured to place Without the employment of solder. It may be remarked that the pressure exerted by the cx-l tremity f of the scratcher or ignitorf maybe increased or diminished by opening the lid or cover A4 and bending theV extremity f downward by means of the fingers or in any other convenient manner. Moreover, inasmuch as the cover A4 is normally retained in a closed position by the pin a, the extremity f of the scratcher or ignitor f is normally held in contact with and presses against the sleeve cor support c. f

g is a narrow strip or ribbonof muslin, linen, or other suitable material, provided with percussion-capsor f ulminating pellets g2, disposed at suitable distances apart along the same. The narrow ribbon or strip g, formed into a coil, is inserted onto the retaining pin or lug b, and then led around the loose sleeve c of the stud-pin or support c, beneath the extremity f of the scratcher or ignitor f, and

, into proximity to the exposed extremity x of the wick and the forward end thereof is passed between the bifurcated pin d', and then coiled around the same, as shown in the drawing. The cover A4 of the oil-receptacleis then closed, so as to bring the extremity fr of the wick a; and scratcher or ignitor finto an operative position with relation to the pellets or caps g2, and the cover A4 is secured in a closed position by turning the members A and A toward each other, so that the pin or stud a6 engages in the slot or groove a8. The disk d is then actuated by the thumb or in any other preferred manner and the narrow strip or ribbon g fe'd upward from the retaining-pin l) around the loose sleeve c of the stud pin or support c, whereby the individual caps or pellets g2 are brought into frctional contact with the scratcher or ignitor f and exploded, and the explosion of the pellets or caps causes the extremity 0c of the wick to be lighted.

The tape, strip, or ribbon g, after its caps or pellets g2 have been exploded simultaneously with the feeding of the same, is wound around the bifurcated pin d of the toothed disk (l until the entire strip has been rendered useless by the consumption of all the capsor pellets thereof, when the strip or ribbon may be readily removedand another inserted by simply causing the lamp to assume the position illustrated in the drawing.

The stud pin or support c, instead of being provided with a loose sleeve c', may be formed in one piece.

Although the present invention has been described with relation to certain mechanism for feeding and exploding the caps or fulminating pellets, still it is not limited to the elnployrnent of such mechanism, because it is applicable in whole or in part to any type of pocket-lam p provided .with means for exploding a fulminating substance in proximity to a wick.

' Having thus described the nature and objects of my invention, what I claim herein as new, and desire to secure by Letters Patent, is-

l. A pocket-lamp havinga divided housing provided with a cover and comprising two members, whereof one is provided with areservoir having a hinged cover through which a wick passes, a scratcher or ignitor attached to said cover, a support disposed adjacent thereto, a fulminate-carrier adapted to be pulled or drawn over the support to ignite the fulminates thereof, and the other of said members provided with a pin adapted to engage Said hinged cover and hold said divided housing together, substantially as set forth.

2. A pocket-lamp having a two-part housing provided with a cover, an oil-absorbent material receptacle mounted therein and provided wiLh a cover having loops struck up therefrom and a Wick extending through said cover, a scratcher or ignitor held in and by said loops, a supported fulminate strip or carrier, and means for pulling or drawing said strip or carrier into contact with said sera tcher or ignitor, forthe purposes set forth.

3. A pocket-lamp provided with a housing having a hinged cover, a disk, and a spring engaging with a lug in said housing and the extremities thereof in contact with said cover and disk, for the purposes set forth.

In witness whereof I have hereunto set my signature in the presence of two subscribing Witnesses.

JOHN HARVEY FARREL.
