AUGUST NOETEL, OF NEW YORK, N. Y.

HEAT-GENERATOR.

Specification of Letters Patent.

Patented Feb. 16, 1909.

Application filed May 16, 1908. Serial No. 488,276.

ful Improvements in Heat-Generators, of

which the following is a specification.

This invention relates to heat generators and more especially to devices in which a small degree of heat may be generated by certain chemicals which may be used in i a parts of the body to impart heat thereto,

various and may be used to warm the hands in cool weather or may be applied to the face in cases of tooth-ache, ear-ache or neuralgia, as will be more fully described in the following specification, set forth in the claims and illustrated in the drawings forming a part of this application.

Figure 1 is a side elevation of the hand warmer constructed in accordance with this invention. Fig. 2 is a vertical sectional view of same. Fig. 3 is a plan view of the heating substance. Fig. 4 is a bottom view of the same.

This device is intended to be constructed in portable form and is of small dimensions on account of the moderate heat which it is designed to impart and is shown in the drawings as being enveloped in a metallic bulb 5 with perforations 6 for the admission of air and also escape of heat. The neck 7 of this bulb fits about a receptacle 8 filled with raw. cotton or other Iibrous substance and into which is to be poured a certain amount of alcohol or similar spirits which it absorbs and gives out in the form of vapor. On the lower end of the receptacle 8 is a nipple '9 over which fits one of the caps 10 or 11, the latter being closed to prevent the escape of the vapor when the device is not in use, but when it is desired to allow the vapor to escape the cap 10 which is open is applied to the nipple. Over the opening of the cap 10 is suspended a button 12 of platen and phosphor sulfur by means of wires 13 passing over hooks 14 at the upper edge of the cap. This platen and phosphor sulfur is sensitive to the vapor of small receptacles for application to the alcohol and when exposed for a short "time to these vapors becomes warm and glows, in a short time becoming sufliciently hot to throw out considerable heat. The formation of the bulb 5 and its location around the button 12 not only protects it against injury but also prevents any damage to outside substances by the redhot button.

In Fig. 2 it will be seen that the cap 11 is embraced by one of a pair of spring fingers 15 which encircle it and serve to retain the cap 10 in its position on the nipple and when it is desired to remove the cap 10 and substitute the cap 11 which puts the button out of commission the cap 10 is also held by these spring fin ers 15 and serves to hold the cap 11 in its pace. The up er end of the receptacle 8 is provided with a loop or eye 16 by which it may be suspended from a chain or cord.

This device may be used in winter and carried in the socket so that it may be held in the hand an serve to warm the same, but the shape may be slightly varied to apply the device to other parts of the body and especially the face where it may be used for certain ailments to keep the flesh of these parts warm.

It is obvious tions of this device may be resorted to so that a gentle heat may be applied to the body where it is necessary to apply the same for surgical purposes.

What I claim as new and desire to secure by Letters Patent is:

1; In a heat generator, the combination with a hollow spherical body, of a receptacle removably engaged with the said body adapted to contain an absorbent substance to be saturated with a volatile liquid, and substance located within the said hollowbody disposed directly in line with the said receptacle, said substance being sensitive to the vapor of the liquid and adapted to be heated thereby.

2. In a heat generator, with a receptacle having a nipple at one end, of a hollow body inclosing the nipple and communicating with the receptacle, absorbent material in the receptacle adapted to contain a volatile liquid, and means removably engaged with the nipple adapted to low when subjected to the vapor of the iquid to heat the said hollow body.
