SPECIFICATION forming part of Letters IPatent No. 654,488, dated July 24, 1909. Application. filed September 21, 1899. Serial No. 731,170. (N0 model.)

To aZZ whom it may concern: I Be it known that 1, Bauer PETERSON, of Dassel, Meeker county, Minnesota, have invented certain new and useful Improvements specification.

The invention relates to devices used in connection with heating-drums; and the object of the invention is to provide means tually cleaned of the accumulated soot and dust.

The invention consists generally in various constructions and combinations, all as hereout in the claim.

In the accompanying drawings, forming part of this specification, Figure 1 is a plan view of a heating-drum embodying my inven- Fig. 2 is a vertical sectional view on the line y y of Fig. 1. Fig. 3 is a horizontal section on the line a: 00 of Fig. 2.

In the drawings, 2 and 3 represent, respectively, the opposite heads of a drum, having the heads are preferablyinclined or converge, and the inner ends of said heads are closed by partitions or walls 6 and 7. A series of holes are provided in said walls 6 and ,7, ar-

the heads, and said holes'are connected bya series of flues 8, communicating with theinterior of the heads 2 and 3 and through which the smoke and products of combustion pass Within said smoke-fines 8 I prefer to arrange a series of smaller flues 9, whose ends extend through the heads 2 and 3and are secured to the outside inclined walls of the same, causing said open air. The drum is designed particularly to be inserted between two sections of stovepipe, and as the smoke and products of combustion enter the end of the dr11m say up through the fines 8, heating the air-flues 9, through which a current of cool air is constantly passing to be heated and discharged the room.

concentrically,with but a short space between them, it follows that the soot will gather upon the walls of said flues and after a time se riously interfere with the heating of the same and in consequence decreasethe heating capacity of the drum. I therefore provide a series of rods 10, one for each hot-air flue, adapted to slide up and down in holes in the top of the drumhead and in the space between said flues and having their inner ends bent at a right angle to the main portion of the rods and looped around the dues 9, the loops being sufficientlyloose to permit the rods to slide freely up and down Within the space between said fiues and scrapethe walls of the same clear of all accumulated soot and dirt, whichfalling upon the inclined lower-end "of the drum will slide down into the smoke-pipe and thence to the fire. Instead of forminga loop at the bottom of the rod I may provide a ring upon each flue, connecting the same withithe vertically-moving rod. 1

With the aid of the cleaning de vice,asabove set forth,the hot-airflu'es of the heating drum may be kept thoroughly clean from soot and other foreign material without the necessity of taking the drum apart, and in this way the highest degree of efficiency of a heating drum may be obtained at all times.

In various ways the detailsof the device may be modified. Hence I do not wish to be confined to the particular construction herein described. 1

Having thus described my invention, I claim as new and desire to secure byLetters Patent I A heating-drum, comprising heads 2 'and 3 having, respectively, smoke inlet and outlet openings 4 and 5, the walls forming the outer ends of said heads being inclined toward their respective openings, a series of smoke-flues 8 connecting said heads, a series of air-flues 9 having open ends extending through said heads and provided one within each of said smoke-fines and concentric therewith and spaced from the walls of the same forming a series of annular smoke-passages between 'theinolined walls of said heads through the 10 said heads, and a series of rods 10 provided opening therein, substantially as described. one within each of said smoke-passages, the In witness whereof I have hereunto set my outaeril enis ofdstalild rods projgetling tlrirouglci hand this 16th day of September, A. D. 1899. sai ea S an 611 inner en S 8111?, oope loosely around their respective air fiues, BENGT PETERSON whereby when the rods are moved up and In presence of down the soot willbe cleared from the walls LoUIs PALMERSTON,
