HEATING-DRUM.

SPECIFICATION forming part of Letters Patent No. 793,368, dated June 27, 1905. Application filed June 30, 1904. Serial No. 214,790.

To all whom it may concern Beit known thatl, FRANK i\ I.(5ri\n.u. \N,acitizen of the United States, residing at Alma (Jenter, in the county of Jackson and State of \Visconsin, have invented a new and useful Heating-Drum, of which the following is a specification.

This invention relates to heating drums-or radiators of that class which are specially adapted to be used in connection with stoves, the same forming a part of the means for the passage of the products of combustion from the stove or place of combustion to the final point of exit.

The invention has for its object to provide a device of this class which shall be simple in construction, easily applied to an ordinary stovepipe, durable, and efticient in operation.

\Vith these and other ends in view the in vention consists in the improved construction, arrangement, and combination of parts, which will be hereinafter fully described, and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of embodiment of the invention, it being understood, however, that I do not necessarily limit myself to the precise structural details therein exhibited, but reserve the right to such changes, alterations, and modifications as come fairly within the scope of the invention and which may be resorted to withoutdeparting from the spirit or sacrificing the utility of the same.

In said drawings, Figure 1 is a vertical sectional view of a heating-drum constructed in accordance with the principles of the invention. Fig. 2 is a horizontal sectional view taken on the line 2 E2 in Fig. l.

(orresponding parts in both figures are indicated by similar numerals of reference.

The heating-drum of my invention consists, primarily, of a casing 1, preferably cylindrical in shape and provided in its upper and lower sides with openings 2 and 3, surrounded by the flanges or collars 4: 5, by means of which the drum may be conveniently connected with joints of ordinary stovepipe, as indicated at 6. \Yhen thus adjusted upon or connected with the stovepipe, the drum 1 will obviously form part of the smoke-passage. \Vithin the drum l is disposed a diaphragm 7, which is of less diameter than the drum, between the outer wall of which and the edge of the diaphragm is an annularspace or ogening 8. The diaphragm T is provided on its under side with radiating arms 9, which extend from the center of the diaphragm and beyond the edge of the latter, said arm constituting means upon which the diaphragm is supported about centrally in the drum or casing. The arms or supporting members 9 ter minate in contact with the wall of the drum, and their outer extremities are bent or deflected, as shown at If), all in the same direction. Arms 11, similar to the arms 9, butdisposed intercurrently therewith, are mounted upon the upper surface of the diaphragm 7, said arms 11 likewise having bent ends 12, deflected in the same direction as the ends of the arms 9 and terminating in contact with the wall of the casing or drum.

It will be understood that in operation prodnets of combustion ascending from the place of combustion and passing into the drum through the opening 3 at the bottom thereof will be deflected in the direction of the outer wall of the drum by the diaphragm '7, the arms 9, having the bent ends 10, serving to deflect the smoke laterally, and thus set up a spiral movement, which will be augmented by the bent ends of the arms 11 upon the upper side of the diaphragm until the products of combustion escape through the opening 2 in the top of the drum or casing. This whirling or spiral movement will not only have a tendency to improve the draft, but will also distribute the products of combustion, which enter the casing in a highly-heated state, toward the outer walls of said casing, whereby the heat will be freely absorbed and radiated into the room where the device is located. hen, as is the intention, the heating-drum is disposed in close proximity to the stove, the diaphragm 7 will arrest and deflect the burning gases ascending from the combustionchamber and without interfering with the necessary draft will tend to moderate the latter and to cause all the heat units to be extracted and utilized, thus enabling a large her.

saving in fuel to be effected without loss of available heat.

Under the construction illustrated in the accompanying drawings each of the flanges or collars 4E and 5 is composed of an inner member 15, having a lug or flange 16, which eX- tends through and abuts against the inner side of the top or bottom of the drum or casing, as the case may be, and an outer member 17, which is connected to the inner member by means of rivets 18 or other suitable fastening means, the edge of the opening 2 or 3 being in either case upset, so as to form a flange 16, extending between the inner and outer members 15 and 17, thus forming a structure of great strength and simplicity and whereby the several parts are securely retained in the proper position with relation to each other. At the bottom of the casing the outer flange member 17 is longer than the inner flange member 15, so that the connecting-joint of the Stovepipe may be inserted within said outer member and abut upon said inner mem- At the top of the casing the construction is reversed in that the inner flange member 15 is the longer, thus enabling it to be introduced into the abutting stovepipe-joint 6, the end of which abuts upon the outer flange member 17. By this simple construction and arrangement of parts the device is materially strengthened and leakage of smoke at the joints of the device is rendered practically impossible.

It is obvious that by the construction herein employed the device may be reversed and utilized with either side uppermost. Another practical advantage of the device is that the upper side of the drum may be utilized for ,ees

the purpose of heating plates or articles of food which may be placed thereon.

Having described my invention, I claim- 1. A heating-drum consisting of a casing having an inlet in its lower and an outlet in its upper side, a diaphragm supported within the casing and of less diameter than the latter, and radial supporting-arms for said diaphragm having bent ends, all deflected in one direction and terminating in contact with the wall of the casing.

2. A heating-drum consisting of a casing having an inlet in its under side and an outlet in its upper side, a diaphragm of less diameter than said casing and supporting-arms upon the under side of said diaphragm, said arms radiating to the outer wall of the drum and having bent ends all deflected in one direction, and radial arms upon the upper side of said diaphragm disposed intercurrently with relation to the supporting-arms and having bent ends deflected in the same direction as the ends of said supporting-arms.

3. In a heating-drum, the combination with a cylindrical casing of a diaphragm of less diameter than said casing, said diaphragm being provided on its upper and under sides with radiating intercurrently-disposed arms extending beyond the edge of said diaphragm and having bent ends all deflected in the same direction.

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

FRANK M. GARMAN.
