FREDERICK J. HILBY, OF CHICAGO, ILLINOIS, ASSIGNOR OF ONE-HALF TO HARRY W. TREAT, OF SAME PLACE.

AIR-WARMING ATTACHMENT FO R STOVES.

SPECIFICATION forming part of Letters Patent No. 413,367, dated October 22 1889.

Application filed May 20, 1889. fierial No. 311,485. (No model.)

To all whom it may concern:

Be it known that I, FREDERICK J. HILBY, a subject of the King of Norway and Sweden, residing at Chicago, Illinois, have invented certain new and useful Improvement-s in Air- Warming Attachments for Stoves, of which the following is a specification.

My invention has for its object to provide an attachment for stoves whereby the waste heat is utilized to warm a body of air which, after being warmed, may be conducted to apartments of the building to warm them.

My improvement consists in a heatingchamber formed by inclosing-walls and having smoke-Flues extended through it, whereby the contained air is warmed, and which is also adapted to receive the radiated heat from the stove either by being placed directly upon it in one construction or by means of a heatdeflecting hcod, which is so placed with reference to the stove and air-warming chamber as to direct the heat into the latter.

In the accompanying drawings, Figure 1 shows the preferred form of construction, Fig. 2 the alternative form, and Fig. 3 a detail.

Upon the stove Ais mounted the air-Warming structure, which has the inclosing side wall B, top wall 0, and bottom wall 0.

D is a partition secured to the side walls B, preferably near the top of the chamber, and E is a second. partition secured across the chamber toward its bottom, but in such manner as to leave an opening between its edge and the side wall.

F represents smoke-fines, which are secured in an upright position, their ends being confined within suitable openings in the plates or partitions D and E. The lower ends of these flues F communicate with the smokeopening G in the top of the stove, and in the construction shown in Fig. 1 a plate E is employed havinga straight portion 6, which is joined to the edge of plate E, and curved portions e, which extend to side wall B at Plate E is provided with an aperture, through which the collar or flange f around the smoke-opening passes- H is the smoke-pipe, which communicates with the top of the chamberand conducts away the smoke after it has passed through the fines F.

In the construction shown in Fig. 2 the heating=chamber is located near the rear of the stove, and the plate E is omitted.

I is a pipe to supply the heating-chamber with air to be warmed.

In the construction shown in Fig. 1, the superposed structure is adapt-ed to be swung into the position shown by the dotted lines, the collar f serving as the pivot on which it swings. The radiated heat enters the cham ber directly in this construction and passes through perforations y in the straight portion of plate E, and after circulating around the smoke-fines F escapes into the hot-air conduit J, by means of which it is led to the apartments to be warmed.

K, Fig. 2, is a deflecting-hood, which is used to cover the front part of the stove and adaptedto direct the radiated heat through the opening b in the wall B.

I prefer to provide a water-chamber L, formed by an open-ended pipe placed inside the heating-chamber, whereby the heatingair is moistened.

The form and size of the device may be considerably changed, and the arrangement of the parts may be considerably varied. Both of the'forms illustrated may be pivotally mounted, as described, and the hood is adapted for use with either form when the chamber is made to occupy only a portion of the top of the stove. Any desired number of smoke-passages may be employed; but I prefer to use sufficient of these flues to provide a large area of radiating-surface about which the air is caused to circulate.

The device may be fitted around the stovepipe; but I prefer the construction above shown and described.

I claim 1. The combination, with a fiat-top stove of an aibwarming attachment therefor, having a heating-chamber formed by inclosingwalls pivotally mounted upon the stove-top and covering substantially the whole thereof, and having suitable air inlet and outlet openings and smoke-passages, substantially as deated heat into the chamber and in conjuncscribed. tion with said chamber covering the whole of 2.
