PATENT HEAT-REGULATING DRUM.

SPECIFICATION forming part of Letters Patent No. 566,149, dated August 18, 1896. Application tiled June 1l, 1895. Serial No. 552,466. (No model.)

To @ZZ whom, it may concern:

Be it known that I, ERASMUS H. DONALD- SON, a citizen of the United States, residing at Cleghorn, in the county of Cherokee and State of Iowa, have invented a new and useful Heat- Regulating Drum, of which the following is a specification.

The purpose of the present invention is to prevent the overheating of an apartment and supply a stove with means whereby the radiated heat can be controlled and directed into the same apartmentor room in which the stove is located or int-o a conveyer or pipe, to be directed thereby to any desired point of discharge or for heating a distant room or apartment. f

Vith these ends in view and suoli others as appertain to the nature of the invention the latter consists of the novel features which hereinafter will be more fully set forth and claimed, and which are illustrated in the accompanying drawings, in which- Figure 1 is a perspective view showing the invention applied. Fig. 2 is a vertical sec* tion of the heat-regulating drum, showing its relative disposition to the stove to which it is fitted, said stove being shown in side elevation. Fig. 3 is a top plan view of the drum.

It will be understood that the invention is to be applied to any form, make, and style of heater and that its construction will vary to suit the style of heater or stove for which the device is intended, and in order to illustrate the invention I have shown the same applied to an egg or round stove of well-known form, and the drum in its embodiment is shown conformed to meet this particular class of stoves.

The heater or stove l has a drum 2 of usual construction, applied to its upper end, and the body or main portion of the stove is encircled by a drum 3, having an inwardly-extending portionlt at its upper end, and which is provided with a series of openings 5 for the escape of the heated air into the room. This inwardly-extending portion 4 may be properly designated as an inner iiange, and is adapted to extend over and close the space between the drum 3 and the sides of the stove or heater l. This drum 3 is provided with legs 6, by means of which it is supported upon the base of the stove or other structure, and

the lower end of the drum 3 terminates a short distance above the plane or base of the stove, so that access can be had to the said stove and so that the latter can radiate heat directly into the room.

A guard or shield 7 is adapted to telescope with the lower portion of the drum 3, and when lowered nearly or quite closes the space existing between the lower end of the drum 3 and the base of the heater or stove, thereby preventing the direct radiation of the heat into the room to the inconvenience of those sitting about the stove after the room has been comfortably heated. This guard or shield 7 is supported within the drum 3 by means of straps 8, which have pivotal connection, respectively, with the drum 3 and the said guard or shield 7. In order to telescope the guard or shield, it is only necessary to turn the said guard or shield, when, by reason of the straps S, the said guard will move either upward or downward according to the direction in which the said guard is turned, thereby providing for lengthening or shortening the drum 3, as will be readily understood.

- For all practical purposes the guard or shield 7 may be considered as an extensible part of the drum 3 in that it provides for varying the length of the same, as previously stated. Any suitable means will be provided for holding the guard or shield at an elevated position, and, as illustrated, a hook '9 is attached to the guard 7 and its bent end is constructed to engage with an opening 10 in the side of the drum 3 for the desired purpose.

A ring ll is mounted upon the inner flange 4 and is formed with a series of openings 12, corresponding in position and number with the openings 5 in the said' flange 4, so as to register therewith when the ring 1l is in one position and close the said openings when at the limit of its movement in the opposite direction, and this ring ll is limited in its movements by a stop 13, working in a notch '14 in the edge of the said ring.

The hot-air pipe l5, for conveying the heat from the drum 3 to a distant point, is suitably attached to the said drum 3 and has its receiving end opposite an openin g in the flange ,and which openin g is controlled bythe ringdamper 11, which operates across the receiving end of the hot-air pipe and over the said IOO opening. Thus it will be seen that bya proper manipulation of the damper 11 the hot air may be completely shut off from the pipe 15 or partially admitted thereto. The parts are so disposed that when the openings 5 are entirely closed the hot-air pipe is in full register with the drum, so that the maximum amount of hot air passes therethrough, and when the openings 5 are entirely open the hot air will be completely shut off from the pipe l5, and by moving the damper 11 to any point intermediate of its extreme movements the hot air can be regulated and controlled, so as to pass partly through the openings 5 and partly through the hot-air pipe 15. The pipe 16 is the ordinary smoke-pipe and forms no part of the present invention.

In order to admit of access to the body of the stove for supplying fuel thereto, the drum 3 will be provided in the side opposite the stove-opening with doors 17, which in the present instance are constructed to slide and by means of which the interior of the stove or heater 1 is readily accessible for supplying fuel thereto or for any other required piurpose.

By providing a single damper to control the escape of heat into the same room with the stove or into the hot-air pipe a simple and compact arrangement is had and the parts are reduced to a minimum number, and by supplying the drum 3 with an eXtensible part the direct radiation of the heat into theroom can be controlled at will, as will be readily understood. When it is not required to utilize the heat of the drum, the said heat can be conveyed into the smoke-pipe 16 or otherwise disposed of, and by slight modifications the invention can be adapted to drums having the ordinary wheel-dampers, so as to direct the heat to the required point for use.

As previously intimated, it is to be understood that the invention is susceptible of application to the various makes and patterns of heating-stoves. Therefore in the embodiment of the same various changes in the form, proportion, and the minor details of construction may be resorted to without departing from the principle or sacrificing any of the advantages of this invention.

Having thus described the invention, what is claimed as new is- 1. The combination with a heating-stove, of a heat-controlling drum inclosing the upper portion of the stove, a telescoping section at the lower end of the drum, connections between the telesooping section and drum, whereby upon turning the telescoping section it will simultaneously raise or lower, and provisions for sustaining the telescoping section in an elevated position, substantially as set forth.

2. The combination with a heating-stove, of a heat-controlling drum surrounding the upper portion of the stove, a telescoping section at the lower end of the said drum, and straps pivotally connected at their ends, respectively, with the drum and the said telescoping section, whereby a turning of the said section will at the same time result in a vertical movement thereof, substantially as described for the purpose set forth.

The combination with a heating-stove, of a heat-controlling drum enveloping the stove and having a series of escape-openings, a hot-air pipe having its lower or receiving end a short distance from and opposite an escape-opening of the drum, and a single sliding damper operating in the space formed between the portion of the drum having the escape-openings and the lower or receiving end of the hot-air pipe, and having openings corresponding in position and number with the said escape-openings of the drum, and having an extra openi-n g to register with the hotair pipe and establish communication be tween it and the drum when the other escapeopenings are closed, substantially as shown and for t-he purpose described.

4. The herein-specified heat-controlling drum, having an inner iange atits upper end in which are formed a series of escape-openings, and which is provided with a telescoping section, a hot-air pipe having attachment with the drum, and registering with one of the said escape-openings and a damper operating between the said flange and hot-air pipe, and limited in its movements and oonstructed to control the escape-openings and the communication between the hot-air pipe and the drum, whereby when the said escapeopenings are uncovered connection between the drum and hot-air pipe is cut oif, and vice versa substantially as set forth for the purpose described.

In testimony that I claim the foregoing as my own I have hereto afiixed my signature in the presence of two witnesses.

ERASMUS H. DONALDSON.
