Specification of Letters Patent.

Patented Feb.i8,1913.

Application filed May S, 1912. Serial No. 696,022.

To all whom it may concern:

Be it known that I, CHARLES E. ADAIR, a citizen of the United States, and resident of Buffalo, in the county of Erie and State of new and .This invention relates to hovers of the self-contained or portable type, such as are adapted for use in a broodcnchamber or house without the necessity of special provision thereirrfor heating the hover, the heating-means being contained entirely within the hover itself and above the level of the floor upon which the hover maybe placed.

The invention relates particularly to a hover, of the type in question, in which. a lamp is employed as the heating-means, and one object of the invention is to provide the brooder with a heating-device and a lampctising of a form which will heat the brooder- .chamber elfcctively and at the same time U ,provide for proper ventilation of the cham- 25 be Another object of the invention is vide against fire risk through overheatin of the lamp-casing, or any other cause; and a third object of the invention is to produce "a construction in which the lamp may be readily removed from the hover-chamber without disturbing the hover as a whole.

' Other objects of the invention, and the features of construction by which they are attained, will be set forth in connection with the following description of the illustrated embodiment of the invention.

In the accompanying drawings:--Figure 1 is a transverse, vertical, median section of a hover embodying the present invention; and Fig. 2 is a horizontal section on the line in Fig. 1, showing in detail the construction and arrangement of the lamp-cas ing and the lamp.

In the illustrated embodiment of thein- I vention. a hover-chamber of the usual form is employed, this chamber comprising a circular sheet-metal upper portion having a flat top 5 and a cylindrical wall 6, and a cur tain f suitable flexible n'iaterial depend- "ing from the lower edge of the wall. This chamber is supported upon adjustable legs 8.

The top 5 of the .hover-ehau'lber hasa wide central opening from whichdepends the cyl ndrical bodv .l of the lamp-casing,

to prothe lower end of this casing being closed airand oil-tight by means of an imperferate bottom 10. The opening in the top 5 and the upper end of the body 9 is normally closed by means of a removable cover 11, which consists of a hollow sheet-metal men ber filled with asbestos or other material having nonconducting and fireproof qualities.

The air within the hover is heatedby means of a radiator, which is in the formof a shallow, wide drum 12. This drum extends outwardly all around the lamp-casing, near the upper end thereof, being in tree communication with the lamp-casing. The

heating-lamp may be of any ordinary or ,13 with a burner 16 and a chimney 17 of ordinary form.

The oil-font 13 is provided, at the top, with a peripheral flangev 14E whicl'i rests upon a ring 15, and this ring is connected, by means of two metal strips 18, with the cover 11. The ring and the strips, in connection with the cover, constitute means by which the lamp maybe raised from the lampcas1ng, the cover being provided, for

this purpose, with a handle ill? by which it may be conveniently lifted. The parts just described also preferably constitute means for normally supporting the lamp, the oil-- font being held a short distance above the bottom 10 of the lamp-casingso as to v de a space into which any oil which may leak from the lamp may collect, thus retaining the oil within the lan'lp-casiug and guarding against risk of fire from this cause.

The air by which the combustion of the lamp issupported is admitted to the lampcasing through lateral air-openings 19, which are protected by wire-gauze, this gauze having a. mesh sutlicient-ly line to prevent the passage of flame through the airopenings. The heated products of combustion fromthe lamp, after their passage through the radia or as hereinafter de scribed, are finally conducted from the lamp- (asing through a vent-pipe 20 which passes upwardly through the cover ll, and this pipe is also provided with a fire-screen 21. of wire-gauze.

The temperature of the cover is regulated by means of an opening in the top 5, controlled by a damper 23 of ordinary form, this damper being automatically opened and closed through a mechanism comprising a time contributing to the ventilation of the lever 24 and a rod 25 connecting the damper with a thermostat: 26, which is located in the upper part of the hover-chamber.

The lower end of the vent-pipe 20 projects downwardly to a point 'bstantially below the radiator 12, and by this arrangement a proper circulation of hot air within the radiator is secured. The products of combustion from the lamp, issuing from the upper end of the chimney 17, strike against t-helower surface of the cover 11 and then spread in all directions into the radiator and along the upper wall thereof, and they are more or lesscooled by contact with the walls of the radiator they descend at the periphery of the radiator and then pass inwardly along the lower wall of the radiator,

[thus returning to the lamp-casing. The partially cooled gases then descend within the lamp casing to the lower end of the ventpipe, through which they are finally discharged. The downward extension of the vent-pipe prevents the products of combustion from at once issuing through the outlet, causing them first to ascend and flow through the radiator, as just described.

The provision of air-inlet openings in the sides of the lamp-casing results in the ventilation of the hover-chamber, since a constant flow of air is produced through the chamber to these openings, and the flow of thisair also acts to prevent overheating of the walls of the lamp-casing, thus maintaining it at a temperature which permits the chicks to-nestle against the casing without injury.

By the arrangement of the lamp-casing and the radiator just described the hoverchamber is efliciently heated, while at the sametime the lamp is inclosed within a casing which is entirely fire-tight. When it is necessary to trim or fill the. lamp this may be conveniently done by raising the cover 11 and the lamp from the lamp-casing, and

I for this purpose it is necessary only to have its access to the top of the hover, the hoverchamber being in no way disturbed in the operatibn Since the lamp-casing terminates at or above the level of the floor or surface upon which the hover is supported, it is unnecessary to provide any opening or recess in this floor, to receive the lamp casmg so that the hover may be used in any closed compartment and moved from place to place as convenience may requine, or it may, in fact, be used in the open ail}, being complete in itself.

When the temperature within the hoverchamber rises above a predetermined degree the thermostat 26 opens the damper 23 auto-- matically, and permits more or less heated air to discharge from the hover-chamber, thus automatically regulating the temper-w ture within this chamber and at the same hover chamber and extendin downuardlv.

from the top of the chamber, the lamp-ca ing being closed at the top, a wide, shallow, annular radiator projecting horizontally around the lamp-casing, near the top thereof, and closed except at the center, where it freely communicates with the casing, and a vent-pipe passing upwardly through the top of the lamp-casing near the side thereof, the lower end of the vent-pipe being at a sub stantial distance below the radiator so as not to receive directly the heated gases from the lamp.
