Letters Patent No. 91,833, dated June 29, 1869; a-nteflated June 15, 1869.

The Schedule referred to' in theael Letters Patent and making part of l the same,

To all whom t may concern.-

Be it known thatwe, JOHN ERPELDING and WIL- LIAM E. HUTTMANN, .both of Chicago, in the county of Cook, andS'tate of Illinois, have invented certain new and useful Improvements in Pocket-Lamps; and we do hereby declare that the followingr isa full, clear, and exact description thereof', reference heilig had to the accompanying drawings, making part of this specitication, and to the letters of reference marked thereon, like letters indicating like'partswherever they occur. Y

To enable others skilled in the art to construct and use our invent-ion, we will proceed to describe it.

Our invention consists ot' a combined pocket-lamp and match-box, of novel construction, as hereinafter explained.

Figure l is a side elevation ofthe same, closed;

Figure 2 `is a longitudinal section ofthe same;

Figure 3 is a side elevation of the same, representing both thel lamp and match-box open; and

Figure 4 is a transverse section of the same, taken on the line x-x of iig. 2. y

To construct our lamp, we form two cylinders or cases, a and b, one being'less in diameter and slightly shorter than the other, as represented in section in.

gA bottom is soldered to the inner case l, and it has a wick-tube, e, and screw-cap, j, fitted to its top, in the ordinary manner," after which it is secured to the outer case a, at the top, by means of an annular ange or ring, as represented in iig. 2, thus holding the case l suspended within the case a, the two being arranged concentricallly, so as to leave an annular space or chamber, t, between them, for the reception of matches.

The simplest method of constructing these cases is to take the ordinary drawn-brass or other metal tubing, of two sizes, and ,cut them into pieces of the proper length; or, the inner case may be formed with bottom complete, by drawing it into the required form, in the same manner that metallic cartridges are formed. s

A hingedv lid, k, is secured to the bottom of the outer case a, and has a spring, t, arranged on the inside of case a, in such a manner as to keep the lid k closed, except when power is applied to open it, the

spring being shown in tig.- 2, with the lid closed, and the lid being shown open in iig. 3.

To the cup or reservoir Z, is fitted a screw-top, f, provided with a wick-tube, c, and within thel reservoir, depending from the top, is secured a finely-perforated tube, g, which surrounds the wick, and reaches down to 'a sponge, h, which fills atleast one-half of the reservoir, and which is intended to absorb the bulk of the oil, and prevent it from splashing or leaking out, in case the lamp should beteinporarily inverted, as may at times be necessary, to withdraw matches or insert thesanie. If' desired, the cavity may be filled nearly full of sponge.

A hinged cap, b, is fitted to the case a, so as to shut down over-the wick-tube, and close the whole securely, in which condition it may be carried convenientlydu the pocket.

AWithin the top portion of the cap or lid b, is yplaced a reflector, c, which I'nay consist of any suitable material, the raising of the lid to the position shown iu proper position to tig. 3 bringing the reflector into throw the light forward.

By these simple means, I provide a cheap, compact, and efcieut combined lamp and match-box, that can be carried in the pocket, or packed in a trunk, or other conveyance, where it will always be ready at hand, whenever a light is required for any purpose whatever.

XVe areaware that pocket-lamps have heretofore been described as composed of a single case, divided into two compartments, hy means ot'a diaphragm or division-plate, and, therefore, we do not' claim such but, having thus described our invention,

1. A pocket-lamp, consisting of a lampcase,'l, and

an oiiter case, a, united, as shown, so as to leave an annular chamber, t, between them, for the reception of matches, substantially as herein described.`

2. The -reiiector c, located in the top otthecover b,

and arranged to operate as described,
