To all whom t may concern: i

Be it known that I, MAXTMILTAN J. O'r'io,

a citizen of the United States, residing in the borough of Manhattan, city, county, and State of New York, have invented new and useful Improvements in Gas-J et Heaters, of which the following is a description.

This invention has reference to heating apparatus and, particularly, relates to devices or apparatus applicable to fixtures, brackets, or arms for supplying gas light, or applicable to gas burners of any type.

Among the objects of my invention may be noted the following: to provide a gas jet heater with nie-ans by which the temperature of the surrounding atmosphere', in a room for example, may be raised through a medium applied to the ordinary fixture for gas lighting purposes; to provide a heating apparatus which may be applied to gas burners, iixtures, etc., of any kind or description, either in combination with the lighting means or to the exclusion thereof, for the purpose of furnishing heat to the surrounding atmosphere; to provide a simple, light, inexpensive heating device applicable to gas jet fixtures for the purpose of providing a suiiicieiit degree ofwarmth or heat in rooms where there is no heating apparatus or where the heating apparatus is inadequate for the purpose; to provide simple, economical, strong and durable means for heating rooms by gas and foi-applying the same to the ordinary gas fixtures or brackets, or to a specially constructed support or bracket which is portable and maybe set upon a table or similar support or upon the floor or otherwise.

With the foregoing objects in view and others which will be detailed during the course of this description, my invention consists in the parts, features, elements and combinations thereof hereinafter described and claimed.

In order that `my invention may be clearly understood, I have provided drawings wherein: y

Figure 1 is a View in elevation showing heating apparatus adapted to be appliedto any gas fixture or other support" `similar thereto ;V -v Fig. 2 is a vertical section on line 2:-2, Fig.l 1 of the apparatus;

Fig. 3 isa perspective view o f the heating drum of iii-y' apparatus shown detached `trein the4 latter;

Fig. l is a view in elevation showing my h eating apparatus applied to the ordinary single arm lighting fixture; I

Fig. 5 is a top plan view showing my apparatus applied to a bracket or fixture in combination with lighting means; and

Fig. 6 is a view in elevation showing the saine combination of means as in F ig. 5 applied to a portable support. adapted to be -connected to a gas source.

Referring to the drawings, the numeral l indicates the cylindrical body of my apparatus, the same being open at its opposite ends, and provided near its lower end withv a large aperture 2 through which the gas at the burner 3 may be lighted. The burner 3 is conventional in form and may be of any known desired or preferable make.` Spe cifically, it` forms no partof my invention. The cylindrical body l, near its lower end, is also provided with a plurality of apertures 4C .encircling the body andadapted to supply a suflicient amount of air for combustion purposes, in combination with the apertures 5 in the conical supporting shell 6 rigidly secured in any suitable manner at 7 to the tubular stem 8 of the burner 3, the

y said stem 8 having an aperture 9 which also furnished air to aid in combustion of the gas. The conical shell 6 is, at itsupper open end, provided with an inturned, substantially U-shaped flange i0, which receives within its opening the outturned flange 11 of a ring member l2 removably secured within the base of the cylinder below the encircling row of apertures 4. l Thus the cylindrical body is supported removably upon the ring 12, which ring in turn is supported by the shell 6, and the latter in turn supported by the stem 8 of the burner, said stem extending below the shell 6 a suicient distance to provide a fixture for application to the usual vburner-valve 13 carried by the usual bracket or arm 14C fixed to the usual source of supply. The shell 6 is also secured to, and braced by, the stem V8 of the burner by means of a diaphragm l5, through the center of which the i stein 8 passes, andwhich'diaphragm, at its This aiiords a very iirm support for the heating apparatus as a whole, which latter as before noted, is removably secured to the said support, the engagement between the ring v12 and the cylinder 1 being trictional, tight and steady. By making` the cylinder and itssupportedparts removable, as noted the drum supported in the cylinder can be removed when necessary for repairs or replacement.

The drum `mounted within is shown as composed,-Figs. two end members or disks 19 provided with a plurality o't apertures 2i in one or more groups, as may be desired or found necessary, said disks being connected together by the perforatedV cylindrical tubes 22 which, at their opposite ends, are provided with a plurality ot lugs 23 turned over and secured upon both surfaces et the disks, this means aiiording a ready and satisfactory way oivsecuring the heating or the cylinder 2 and 3,-o't and 20, each radiating tubes to the disks 19 and 20. The

Yproviding thereby a very effective deiiector heating drum thus composed is suspended within the inclosing cylinder 1 by means of bent arms or brackets 2a secured by vertical intermediate portions to the upper end ot the cylinder 1 by means of screws 25 and nuts 26. The arms, at their lower ends, are each bent inwardly to provide a horizontal support 27 on which the disk 19 is set and to which said disk is secured by means of screws 28 and nuts 29.' Thus, with a plurality of supporting` brackets or arms, such as 24, the drum is rigidly mounted within the cylinder 1, clear of the walls thereo't, a spacebeing provided between the disks 19 and 2O and the cylinder 1 for the passage ot heat from the chamber 30 between the burner` 3 and the disk 20, in which chamber the burner 3 is located. Between the heating tubes 22 and the wall otthe cylinder another chamber is provided, and between the upper disk 19 and the heating tubes and the'upper end of the apparatus still another chamber is provided, as presently described. The brackets or arms 24 are outwardly bent so as to extend a considerable distance beyond the cylinder l and then are inturned, as at 31, to provide a ll-shaped iiange or support for the flanged open end 32 of the conical dome 3S of the apparatus. Bracket arms 24 rigidly support the dome 33 in position directly above the cylinder 1 and separated from the latter by a. sur'licient space to allow of the escape of the heat into the surrounding atmosphere. Preferably, the dome 33, at its lower end, is considerably greater in diameter than the cylinder l,

for the heat and enabling the said dome to thereby carry the heat outwardly a considerable distance from the cylinder 1 into the surrounding atmosphere. The dome 33 thus provides an extensive chamber above the disk 19 and the heating drum; and said dome is provided with a plurality ot apertures 3a suitably arranged for the escape olf heat from within the said chamber directly into the surrounding atmosphere. .\t its upper end, the dome is provided with a ccntral aperture surrounded by a short inturned 'tiange 35, upon which rests a tei-rule or sleeve surrounding a screw boli" 3T, which extends through the aperture in the dome 33 and is securely held b v :l nul ils on the threaded end oit the bolt. cap plate 3S) conical in Vtorni is mounted upon the terrule 3G and has the stem ot the bolt 3T passing theretlnrough. Thus. the head of the bolt tightly ecures the cup plate 2in upon the :terrule 3G and the .support oi' the said cap plate upon the dome 33 is unite rigid. The Yfunction oi the cap plate is to prevent the heat rising from the dome. or any products of combustion passing through the dome. reaching the ceiling. Thus the possibility oit blackcningor soiling the ceiling' is eliminated. The cup also bas the function of deflccting the heut rit-:ing through the dome downwardly and outwardly into the surrounding` atmosphere.

The heating apparatus produced as thus described may be, as shown in lig. l, mounted upon the iixture 1li, which is the usual gas bracket arm, after removing the lighting tip therefrom. Il? it is desired to obtain light and heat simultaneously. the entire burner and tip can be removed from the valve member 13 oit the bracket arm and in its place a fixture can be applied as shown in Figs. and G, the fixture in this instanci` being a T-shaped member 40, the stem ol' which is applied to the valve member lil oi the bracket arm 14.-, and the head ot which has extending therefrom in opposite directions the pipes or arms Lll and 112, the arm L11 having my heating ap] nuatus applied thereto, as shown in Fig. 4. and the arm A,li having the usual gas cock and burner indicated generally by 4163 applied thereto. Thus, heat and light can be furnished at the same' time through a single fixture ,il having applied thereto the attachment l0-42; and heat or light may be obtained as desired. Instead oit supporting my heating apparatus upon a fixed arm or bracket such as la, it may be applied to n heavy portable base L14, as shown in Fig. G, the same consisting oi a weighted or very heavy circular or other shaped member adapted to rest on a table, the floor or otherwise, and having extended centrally therefrom a stem 45 connected with a fixed pipe 1G. in turn coupled in suitable manner to a flexible pipe 47 secured to the source of supply.

The stem 45 of the base or support t1 has the heatingand lighting ixture shown in Fig. 5 applied thereto in the same manner as it is applied te the bracket arm 14. Thus a lighting and heating device portable in character can be set upon a table, in a room or otherwise; to provide either or both heat and light in manner similar to a drop light, students lamp, etc.

From the foregoing it will be seen that I have' produced a very simple and effective heating apparatus which is adaptable to the ordinary gas jet or bracket arm as a substitute for the light burner, or Which can be so applied to a supporting member or device as to afford both light and heat simultaneously. It Will also be seen that my heating device will supply a very great amount of Warmth, and, when it is thoroughly heated, Will radiate heat quite extensively into the surroundingatmosphere and afford a sufficient heating medium even in very cold Weather.

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

l. A gas jet heater comprising a cylindrical body; a heating drum and means for suspending the same Within the body; means at the bottom oi the heater for supporting the 'same upon a gas fixture; a dome mounted upon the body; and a cap mounted centrally upon the dome with its circumference free to prevent products oi' combustion from rising.

2. A gas jet heater comprising a body portion; a perforated base entirely closing the body portion; a burner mounted centra-lly in the base and having an extended stem for supporting the heater upon a gas fixture; a drum consisting of a plurality ot' perforated tubes joined at opposite ends by disks; and means for suspending said drum within the body portion out of contact with the latterand above the burner.

3. In combination With a support through which a supply of gas may be obtained; a h'xture applied thereto; a source of light secured to one end of the fixture; and a source of heat secured to the other end oi? the ixture; said source of heat comprising a supporting base; a' cylindrical heat radiating body; a heating drum Within said body; a dome mounted on said body; and a cap mounted upon the dome.
