LAM P H EATER.

SPECIFICATION forming part of Letters Patent No. 495,199, dated April 11, 1893.

Application iiled December 29, 1892. Serial No. 456.626. (No modal.)

To all whom it may concern:

Be it known that I, CHARLES HEMJE, a citizen of the United States, residing at Annapo lis, inthe county of AuneArundel and State of Maryland, have invented certain new and useful Improvements in Lamp Heaters; and I do declare the following to bea full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.l

My invention relates to improvements in heating or increasing the temperature in rooms by means of lamp heaters, and the ob- Jects of my improvement are, first, to create an increased draftin lamps and consequently a better combustion; second, to utilize the heated air formed under the lamp shade and around the chimney, and superheating it by letting it pass over the top of the chimney; and third, by radiating the air so heated by radiation from und er a detlector, for heating purposes.

The invention consists in the construction of certain details and arrangement of parts as will be more fully described hereinafter and specifically pointed out in the claims, reference being had to the accompanying drawings and the letters ot' reference marked thereon.

Like letters indicate similar parts in the different figures of the drawings, in which:

Figure l is a View of an ordinarylamp with my improved heating apparatus held in position by means of a suitable tripod attached to the upper rim of the lamp shade. Fig. 2 is a modification of the heating apparatus, radiating the heated air through channels formed in its upper part, and being placed on a reversed tripod suspended from the top of the chimney. Fig. 3 is a modification of the heating apparatus, arranged so as to stand directly on the lamp shade,

With any ordinary lamp A,the air in the immediate vicinity of the chimney B andl under the shade S, is heated to a certain eX- teut, but the effect of this is quickly lost in the surrounding cold air. By placing around the chimney B, and partly surrounding the same, a heating shade or globe C, as shown in the accompanying views, the partly heated air which has been formed beneath the shade S, is drawn upward as indicated by the arrows shown, (Fig. 1,) and in its upward path, is still further heated or superheated by the heat of the chimney B, and on account of y the heating shade or globe C being contracted in sectional area, just above the top of the chimney B, the ascending, gradually heated air passes directly over the top of the chimney B, Where it is superheated, and after having attained the greatest possible degree of heat, it is discharged or radiated through the circumferential opening formed by the upper flange of the heating shade or globe C with a deflector D.

The heating effect of this apparatus is instantaneous as soon as the lamp is lighted, and in a comparatively short time the temperature in a moderate sizedroom canbe raised from 100 to 12C above the normal temperature.

It is not claimed that the invention takes the place of a stove, but it is a most valuable assistance in insufficiently heated rooms and in bed rooms and sick chambers which have no other means of heating; it eectually dispels all dampness and thoroughly dries the atmosphere, which is so very desirable and necessary to health, and this benefit, obtained without additional cost as to oil or fuel, would be lost without the use of the apparatus.

It will readily be seen, that for obtaining the best possible results, it is necessary that the heating shade or globe C should extend downward over the top of the chimney B to such a depth that the heated air formed under the lamp shade S is quickly and directly drawn into it without loss of heat and that its contraction just above the top of the chimney B Will tend to still further increase the temperature of the ascending air, as, at that point it is directly acted upon by the greater heat coming from the flame. Similar to all other hot air heating apparatus, the force with which the heated air leaves the apparatus, depends entirely on the temperature to which the air can be heated Within it.

The manner of attaching the heating shade or globe C to the lamp is shown in the various views of the drawings.

As shown in Fig. l, a tripod or other suitable arrangement, on which the heating shade or globe C stands, is attached with its legs on the upper rim of the lamp shade S; as shown in Fig. 2, the tripod is reversed and suspended from the top of the lamp chimney B, while in Fig. 3 the tripod is dispensed with and the heating shade or globe C is made deep or high enough to stand directly on the top of the lamp shade S. For bracket or hanging lamps the heating globe can be suspended from above in any convenient manner.

The apparatus may be made of glass, porcelain, spun or stamped metal or any other suitable material, and for convenience of manufacture may be made in two separate parts, the top or detlector D being, in that case, connected to the lower part or globe C in such a manner, as to form a circumferential opening for the discharge of the hot air.

To readily remove the apparatus from the lamp, when hot, it should be provided at the top with a suitable eye d or its equivalent.

As shown in Fig. 2, the discharge ot' the hot air takes place through a number of radiating channels, which may conveniently be formed by corrugating the corresponding iianges of the upper and lower parts as shown, or by other suitable means.

While the apparatus can be used with any ordinary lamp, -the best results will be obtained from a center draft lamp, or from Argand burners when used with gas.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is

Il. The combination of a lamp with a heating globe, suspended or supported substantially as shown, the globe being contracted above the top of the chimney, forming a neck from which a flange extends outwardly, and a deflector arranged above the iiange of the globe, the space between the flange of .the globe and the deiiector containing any deslred number of channels radiating from the neck toward the periphery of the flange, substantially as and for the purpose set forth.

2. The combination ot a lamp with a heating globe, suspended or supported substantially as shown, the globe being contracted above the top of the chimney so as to form a neck from which a flange extends outwardly,

and a deflector, arranged so that it forms,

with the outwardly extending flange of the globe, a circumferential opening for the escape of the hot air, substantially as described.

3. As a new article of manufacture theherein described heating attachment for lamps or gas burners, consisting of a globe which 1s contracted at its upper end so as to form a neck, a plurality of channels radiating from said neck, a deiecting plate, and a holder by means of which the globe can be attached to the lamp, substantially as and for the purpose described.

In testimony whereof I afiix my signature 1n presence of two witnesses.

CHARLES HEMJE.
