DEVICE FOR HEATING AND LIGHTING APARTIVIENTS.

SPECIFICATION forming part of Letters Patent No. 554,591, dated February 1 1, 1896. Application tiled January ll, 1895. Serial No. 534,552. (No model.)

To all whom it may concern:

Be it known that I, PETER FRASER, of Whitman, in the county of Plymouth, State of Massachusetts, have invented certain new and useful Improvements in Devices for Heating and Lighting Apartments; and I do hereby declare the following' to be a full, clear, and exact description of the same, reference being had to the accompanying drawing, forming a part of this specification, and'to the letters of reference marked thereon.

The invention has for its object to provide, primarily, a heating device which shall be capable of utilizing in-the most efficient manner all of the heat derived from the flame of a burner, be it coal-oil or gas, to heat a body of air and distribute the air so heated through the apartment, a further object being to provide a convenient arrangement of devices whereby the elevation of the heater and burner may be changed at pleasure.

The invention consists in certain novel details of construction and combinations and arrangements of parts to be hereinafter described, and pointed out particularly in the appended claims.

The accompanying drawing represents in section a heater, together with a burner attachment embodying my present invention,

certain of the parts and the supporting mechanism being shown in elevation.

The lett-er A indicates a burner, such as a coal-oil lamp which gives a good strong iiame, preferably of the Argand type, or a gas-burner of similar character. This burner is supported on the lower end of a slide carriage or frame B, which at the upper end carries the heating mechanism to be presently described.

The carriage or frame B is mounted to slide on a vertically-arranged bracket or way C, which may be secured to the wall or other support at top and bottom, as shown, and to facilitate the adjustment of the frame or carriage on its bracket or way a counterweight D, sliding in a boxing D and connected to the carriage by a iiexible connector d passing over a pulley d', is provided. The counterweight balances approximately the weight of the heating device and burner, and in order to hold the carriage in its adjusted position should a slight excess of weight lie on one side or the other, occasioned, for instance, by

the consumption of oil, I provide a spring E, having its ends passed beneath movable yokes E' extending around the bracket or way and attached to the carriage or frame B by bolts or pins e at top and bottom. The center of this spring bears against the carriage and forces the latter into frictional contact with the bracket or way, and this friction is sufticient to prevent any accidental movement of the devices, although it permits of their adjustment when desired.

The heating mechanism proper consists essentially, first, of a relatively long narrow dome or chamber suspended directly over the burner-chimney, preferably with its lower edge below the top of the said chimney and in position to receive all of the productsheated air, gaseousproducts, Ircpassing out of the chimney. At the top this dome or bell, which I shall hereinafter term the radiator F, is preferably provided with small perforations f to allow the products to escape and insure a circulation and change of air within the radiator. This radiator is preferably suspended on a central pivot at the top, and it will be particularly observed that this radiator is of relatively small diameter and great length. Thus the highly-heated products entering the same pass rapidly up and heat the whole of the radiator-walls to a very high degree, thereby providing a radiating-surface of comparatively large area, and with a View to further increasing the efficiency of the radiator it is preferably constructed of copper, which material transmits the heat from the interior column of heated air or products to the exterior of the radiator with very great facility.

Outside of the radiator and entirely surrounding the same is a hot-air conductor G, having a flaring or bell mouth G' at the lower end and terminating at the top in a hood G2, beneath which hood are formed a series of exit-openings g for the escape of hot air passing up through the conductor. The bellmouth of the conductor catches all of the hot air passing up around the burner proper and all of the products escaping from the radiator either at the bottom or top, and these, united with the large body of air flowing rapidly up through the conductor, and being heated to a high degree by the radiator, furnish a very large volume of hot air to the apartment. This ICO heated air may be allowed to iiow out naturally if desired, but I prefer to dissipate it laterally by means of a fan-wheel I-I arranged vertically, or on a horizontal axis, opposite a lateral opening h. This fan is driven through a pair of beveled gears I from a horizontallyarranged motor-wheel K, located in the conductor immediately above the radiator, and in position to be driven bythe ascending col umn of heated air.

In the preferred construction the fan mechanism is preferably mounted in an independent section G of the conductor G. Thus it may be removed in its entirety and the hood G2 fitted down directly on the conductor.

As before stated, the radiator is preferably suspended from a single pivot at the top, which in turn may be supported from a crossbar, such as m, and at the bottom the radiator is held against excessive vibration by means of a series of springs, such as M,which springs also serve to center the radiator over the burner under all conditions of use, and at the same time permit of a certain degree of flexibility or yielding, which is desirable in order to permit of the device being handled and of the radiator maintaining its true vertical position, so as to secure the greatest efiiciency.

The burner being located beneath the level of the conductor and radiator is left exposed and may be utilized as an ordinary gas or lamp burner for lighting apartments, and in addition the flaring mouth G and bottom of the radiator may be made in the form of reflectors, which will intensify the light thrown down from the burner to a certain degree. Thus with the combination shown not only is the heating effect of the burner vastly increased, but the light is also properly directed so as to be capable of utilization to the greatest advantage.

Having thus described my invention, what I claim as new is- 1. In a device such as described, the combination with the burner, its chimney, and the substantially cylindrical hot-air conductor having the iiaring mouth at the bottom and a discharge-opening at the to p, of the long` approximately cylindrical radiator suspended concentrically within the conductor with its lower end at the top of the chimney, means for positioning and independent supports for the burner and conductor; substantially as described.

2. In a device of the character described, the combination with the burner, its chimney and the relatively long narrowr radiator suspended over the chimney in position to receive the heated products passing therefrom, of the flaring-mouth conductor surrounding the radiator with its walls parallel therewith and springs for preventing the excessive swinging of the radiator within the conductor 5 substantially as described.

3. In a device of the character described, the combination with the burner, the relatively long narrow radiator suspended above the same in position to receive the heated products from the burner, the ilaringnnouth conductor surrounding the radiator, the horizontally-arranged fan in the upper end of said conductor and the vertically-arranged fan driven by the horizontal fan i'or dissipating the heated air passing through the conductor; substantially as described.

4. In a device of the character described, the combination with the vertical bracket or way of the carriage sliding thereon, the friction-brake for holding said carriage in adjusted position, the vertically-arranged radiator and conductor mounted on the carriage and the counterweight for balancing the weight of said parts; substantially as dcscribed.

5. In a device of the character described, the combination with the vertically-arranged bracket or way, the carriage sliding thereon, the friction-brake for holding the carriage in adjusted position and the counterweight, of the burner mounted on the lower end of the carriage and the radiator and haring-mouth conductor mounted on the upper end of the carriage whereby the level of the heater and burner may be simultaneously altered; substantially as described.
