*SPE'CIPI'CK'I'ION'fOrming part0! Letters Patent No. 366,709, dated July 19, 1 87.

Application filed December 3, 1856. Serial No. l-iflfiilil. (ModeL) To aZZ whom it 11mg concern:

Be itknown that L/HENRY E. AMOORE, a subject of theQueen of Great Britain, residing at Yokohama, in the Empire of Japan, have invented a new and useful Pocket Hand-' lVarm'er, of which the following is a specification.

- My invention. relatesto portable warmers for the hands, and for other purposes where it is desired to place a heated body in contact with the object to be warmed, or in its vicinity, or to increase the heat .of the surrounding atmosphere.

' The object of the invention is, first, to provide a warmer which can be conveniently carried about the person or applied to any part of theperson where alocal application of heat is required; second, to construct the warmer so that it can'lic'placed in any'p'ositionwnthout liability of the ashes or dust sifting through the air-holes; third, to produce a fuel which will burn freely, produce a gentle but steadyheatfemit no unpleasant odors, and can be conveniently carried about and handled.

In the accompanying drawings, Figure 1 represents a side elevation of my improved handw'armer; Fig. 2, a top view 6f the same; Fig. 3, a longitudinal vertical section of the warmer; Fig. 4, a cross section; Fig. 5, a plan of the under side ofithe cover; and Fig. 6 represents the fuel cartridge or stick.

Referring to the drawings, A represents the case of the warmer, which is made of sheet.

metal, and in a general rectangular form when viewed in front elevation; but it may be made in'any suitable shape to adapt it to any special is convex in the-center,

use. The top edge of the case is provided with a groove, a, which extends entirely around one end, but is terminated a short distance from the opposite end on both sides, as indirated at I) b, and from these points the end and adjacent sides of the box or case are out down to a depth below the bottom of the groove in equal tothethickness of a semi-elliptical plate, (1, which is soldered to the top edges of the case, where they are cut down, as above stated, so that itsupper surface lies flush with the bottom of the groove a. The cover B of the box with projecting horiz'ontal flanges e,whi ch run in the groove a, and thus connect the cover with the box. At one end of the cover a plate, f, of the same shape as plate (I, is soldered to the under or concave side. WVhen the cover is placed on the box-or case, the plate f slides overtime plate d, and

thus a tight joint is formed, which prevents the ashes'and dust from escaping at this point. Thejoint is'made still tighter by means 'of a piece of fabric, g,which is pasted or otherwise fastened to the plate f, and which'projects outside of the cover'when closed, forming thus, in addition to packing the joint, a handle or tab by which the cover can be conveniently drawn off.

The sides and ends of the box or case are provided with numerous small perforations, h, which serve as air-holes or draft-openings for the entrance of air to the interior to support combustion. The top or cover is provided with similar openings, h,

The box or case is covered or mcased 111 a covering orcasiug, D, of cotton cloth, muslin, or other suitable fabric, and the top or cover is lined with a similar material. The object of this covering and lining is to stop or cover the draft-openings in such a manner that while an ample supply of air will be admitted to the burning fuel, at thesame time the ashes and dust resulting from combustion will not be permitted to siftor escape through theperforations. The'fabric does not close the openings sufficicntly to shut out the air. The top or cover Bis also lined with a similar fabric, 70.

The fuel used inthis device is composed of charcoal,which maybe made from hemp, grass, wood, 800., and saltpeter and alum mixed together, or wood-charcoal mixed with and alum, or either one of the latter ingredients alone; but I 'do not limit myself to the fuel composed of said ingredients, as any slowburning smokeless-and odorless fuel will answer thati gnites and burns easily and steadily.

The fuel -E,used in these warmers,is put up in saltpeter paper cylinders Z, forming cartridges or sticks F, a trifle less in length and'width than the in-- lows: The fuel-cartridges may be carried in the box or case, or in a separate receptacle.- VVhcn the warmer is to be used, one'of the cartridges is taken (preferably at the end where the paper is gathered in and tied,) and then replaced in the box. \Vhen well lighted, cover the box. If the application is to be local, place the box on the place where heat is required,- butifitisto be used for warming the hands it maybe placed in the pocket or carried in the. hand.

If the fuel should not burn as freely as desired, leave the cover partly open for a few 1noments,when the exposure will have the de sired effect. 7

The warmer may either be carried in the hand or pocket, as stated, or it may be carried in any other convenient way that may be found beneficial. It can also be used for a local application of heat in cases of pain in the stomach, neuralgia, &c.; and for convenience it can be inserted or carried in a bag or other suitable receptacle of cotton-flannel or other material, for thcpurpose of avoiding the spilling of the charcoal, or the ashes and (lust re sulting from combustion.

I donot confine myself to the manuerofap plying the cover herein described, nor to the use of a fabric to close the draft openings. \Viregauze may, for example, be substituted for the cotton cloth.

I claim-- L. A-pocket hand-warmer consisting of a receptacle for the fuel, composed of a metal out and lighted at one end,

of paper, substantially as box the sides of which are provided with per- 35 foratious and having a casing of cloth coveri ng the said perforations, and a suitable cover, substantially as specified.

2. The combination of a metal box having perforated sidescovered by or incased in .a textile material, and the sides provided with a groove, (1, with a cover which is provided with perforations covered by a lining of textile material, said cover being held in the, groove in the sides of the box and'sliding therein, substantially as specified.

3. The combination of the metal box provided with a groove, (1, and the plate (I, fixed to the sides at one end of the box and flush with the bottom of the groove a, and the cover B, provided at one end with a platc,f, which, when the cover is closed, slides over and rests on the plate (I, substantially as specified.

4. The. combination of the box provided with perforated sides and a suitable cover, the box being covered with a suitable textile fabric and the coverlined with the same, and a fuel-stick composed of a suitable powdered or triturated fuel inelosed in a case or cylinder specified.

In testimony that I claim the lbregoingimproved hand-warmer as my invention I have hereunto set my hand, at Yokohama, Japan, this 29th day of October, in the year 1886.
