POCKET LAM P.

SPECIFICATION forming' part Of Letters Patent No. 454,642, dated June 23, 1891.

Application filed May 15, 1890. Serial No. 351,856. (No model.)

T0 at whom it may concern:

Be it known that I, WILLIAM F. FOLMER, of New York, in the county and State of New York, have invented a certain new and useful Improvement in Pocket-Lamps, of which the following is a specification.

The object of my improvement is to provide a lamp which may be convenientlycarried in the pocket and readily lighted.

I will describe a lamp embodying my improvement, and then point out the novel features in the claims.

In the accompanying drawings, Figure 1 is a front View of a lamp embodying my improvement with the front lids broken 0%. Fig. 2 is a view of the inside of the inner front lid. Fig. 3 is aview of the inside of the outer front lid. Fig. 4 is a transverse sec- 'tion of the lamp. Fig. 5 is a transverse section through the inner lid at the plane of the dotted line 00 :0, Fig. 2. Fig. 6 is a sectional top viewofthe body of the case of the lamp.

Fig. 7 is a side view of one of a number of hooks employed to secure in place pieces of material provided with an igniting substance. Fig. 8 is a transverse section taken at the plane of the dotted line y 3 Fig. 4. Fig. 9 is a portion of a ring having embossments and igniting substance thereon.

All the views are made on an enlarged scale.

Similar letters of referencedesignate corresponding parts in all the figures.

A designates the case of the lamp. It may be made of any desired number of parts. If desired, it may be made in precisely the same manner as an ordinary watcli-case nainely, of a body made in the form of a ring with lids hinged to opposite sides. Perhaps it will be preferable to form one side integral with what would be the body portion in a watch-- oil and will be filled with cotton or similar material to keep the oil from moving about.

It is shown as made of cylindric form and as resting against that side of the case which is opposite the lids A A It may be secured by solder or otherwise. This reservoir may be advantageously made of sheet metal: Ithas a filling-mouth b, which is shown as made in the form of a screw-plug, so that it may readily be removed and replaced. 1

A wick-tube 1) extends from the reservoir. Preferably this wick-tube consists of a portion extending outside the reservoir obliquely toward the lids A A and another portion extending obliquely into the reservoir. The 6 5 advantage of extending that portion which is outside of the reservoir obliquely arises from the fact that thus any tendency of the inner lid A to force the wick down in the wicktube as saidlid closes is obviated. Prefer- 7o ably the wick-tube will extend through that portion of the reservoir which is near the stem A of the lamp-case. Around the outer extremity of the wick-tube I preferably arrange a flaring collar b for the purpose of catching any oil which may run over from the tip of the wick. That portion of the wicktube which is surrounded by this collar will preferably be perforated, so that any oil caught by the collar may run back into the wick.

The lid A has an opening a opposite the outer end of the wick-tube. The wick is free to protrude through this opening, and the flash resulting from the explosion of igniting 8 substance which is employed in the lamp may pass through this 'opening to the wick. Opposite this opening the lid A is preferably provided with a pad or cushion afgmade' of or faced with asbestus, so that when said lid is closed the flame will be extinguished. The lid A may be formed to constitute a reflector, or may be provided with a reflector or lens for the better utilization of the light produced by the lamp. I have shown a reflector 5 a attached to it. This reflector may be made of any suitable material-as, for instance, polished metal.

Having now given a general description of the parts whereby the light is produced, I Ice will now describe certain other features which provide for igniting the lamp without the use of a match.

- designates a number of pieces of paper of like material made in the form of rings and provided with pellets or small portions a of any suitable igniting substance. Each of the rings preferably has two circular rows of these pellets or portions of igniting substance. It will be advantageous to provide circular embossments concentric with the edges of the rings and to arrange the pellets or portions of igniting substance upon the same. These rings are arranged one against another, so that the lamp may be supplied with a number of them at one time, and as each becomes used up it may be readily removed.

In the lamp-case is a scratcher for effecting the ignition of the igniting material. In the present example of my improvement the scratcher is stationary, excepting only that it is capable of a certain adjustment, which will be more fully explained hereinafter, and the rings are rotated to subject the pellets or portions of igniting substance to the action of the scratcher. The rings 0 are carried by a rotary wheel D, which in the present instance is a crown-wheel. This wheel may be made of sheet metal. It will be made of as large a size as possible to be contained by the watchcase, and the rings 0 will be accommodated between it and the circumference of the reservolr. wheel in position will be to form a rabbet b in the bottom or back of the reservoir and to extend the inner edge of the disk-like portion of the crownwheel into this rabbet. Provision is afiorded for imparting a rotary movement to this crown-wheel by means of a' gear-wheel E, mounted on a spindle F, ex-.

tendingthrough the stem A and provided at the outer extremity with a handpiece F. In order that there may be a longitudinal movement of this spindle for the purpose of unfastening the outer cover A in a manner common in watch-cases, the gear-wheel E is somewhat elongated, so that, notwithstanding such movement of the spindle, it will remain in gear withthe crown-wheel.

The rings 0 are provided at intervals with slots 0, and through these extend rods d, which at one end are fastened to the disklike portion of the crown-wheel and at the outer end are provided with hook-like projections d. The slots 0 of the rings 0 and their elongation is in the direction of the circumference of the rings. jections at the outer extremities of therods 01 extend in the same direction as the slots 0 are elongated. Owing to this the rings may springs for forcing them upward against the hook-like projections of the rods d. Springs A convenient way of securing this The hook-like pro d may advantageously be coiled around the rods (Z for this purpose to bear at one end against the disk-like portion of the crownwheel and at the other end to push the rings C outward. Preferably a ring-shaped platform G will be used beneath the rings 0, and in such case the springs (Z will bear against the back of this platform.

It will be readily understood that after the pellets or portions of igniting substance of the outer ring shall have been used this ring may be readily detached by givingit a slight rotary movement to disengage it from the hook-like projections of the rods d, and that thereupon the next ring will be pressed forward into the place previously occupied by the one removed. As the crown-wheel is rotated the rings 0 will of course be similarly rotated, inasmuch as they are carried by it. This rotary movement brings the pellets or portions of igniting substance of the outer ring into contact with the scratcher, which is aflixed to the lid A. S designates this scratcher. In the present instance it is made of a rod of thin metal, pivotally connected to the inner side of the lid A by meansof a screw or rivet .9. At its free extremity it is provided with a number of prongs, which will act upon the pellets or portions of igniting substance on the outer ring 0. This scratcher is pivoted in place so that it may oscillate into apositionto act upon either of the two through the slot in the lid A, affords provision for adjusting the scratcher into either of the two positions which it is intended to assume for this purpose. When adjusted into either of its positions, it will fall into one of two notches which are provided in a retaining-piece .9 that is fastened to the inner side of the lid A. The scratcher being resilient is free to yield to pass from one of these notches into the other.

The lid A will preferably be opened by'a spring. I have shown aspring H extending around the interior of the-body of the watchcase and having at one end a projectionh for bearing against the lid A and at the other end a projection h for engaging an opposite portion ofthe lid A to fasten it. The end portion which has the projection 71/ formed upon it is intended to engage with a circumferential groove in the spindle For with a shell otherwise provided on said spindle, so that when said spindle is pressed inward the projection 71. will be disengaged from the lid A and the spring H will then open the lid. The spring H may be simply held in place by its own resilience, pressing against the interior of the body of the case.

Preferably I combine with the stem A and spindle F a ratchet and pawlfor precluding IIO fastened to the inner side of the hand-piece F of the spindle and bearing against the ratchet of the stem. It might be very objectionable to have the spindle turn the wrong way, because it would be liable to disarrange the scratcher and also to cause a disengagement of the rings from the rods.

To ignite the lamp the outer lid A is opened and the spindle is rotated to produce a relative movement between the outermost ring 0 and the scratcher for the purpose of causing an ignition of one of the pellets with which the ring is provided. The flash of fire produced by the lighting of this igniting substance will set fire to the wick. The lamp may then be burned as long as may be desired. To extinguish it, it is only necessary to shut the outer lid. Obviously the proper action of the scratcher would be insured by projecting the pellets of igniting substance upward, and because of this I preferably provide each of the rin s 0 with circular embossments 0 and arrange the pellets of igniting substance upon such embossments.

It will be seen that by my improvement I provide a very simple and compact lamp of convenient form for the pocket and of very attractive appearance.
