1 HEATING ATTACHMENT FOR STOVES.

Application filed March 14, 1928. Serial No. 261,651.

This invention relates to a heating attachment designed primarily for use on laundry stoves and similar devices one of the objects being to provide a simple and efficient device of this character which can be set up readily on the top of a stove and in position where the hot gases escaping from the open top of the stove will enter the attachment and heat it to a high temperature, thereby presenting extensive heat radiating surfaces which will quickly raise the temperature of the surrounding atmosphere.

Another object is to provide an attachment of this character adapted to be closed at the top by the lids of the stove which are transferred from position on the stove to position on the attachment.

lVith the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed may be made within the scope of what is claimed, without departing from the spirit of the invention.

In the accompanying drawings the preferred form of the invention has been shown.

In said drawings,

Figure 1 is a side elevation showing the attachment in position on a stove, a part of the attachment being broken away.

Figure 2 is a vertical section through the attachment, the same being shown in position on a stove.

Figure 3 is a top plan View on an enlarged scale.

Figure 4 is an enlarged section on line 44, Figure 1.

Referring to the figures by characters of reference 1 designates the bottom plate of the attachment preferably so shaped as to fit smoothly on the top T of a stove S which can be an ordinary laundry stove or a cooking stove. This bottom plate has an opening 2 co-extensive with the opening in the top T and an extension 3 is provided on plate 1 which has an opening 1 for receiving the flue collar 5 which projects upwardly from the extension E of the stove S.

Mounted on the bottom plate 1 is a body portion 6 of the extension. This is preferably formed of a sheet of corrugated metal bent to form three corrugated sides and one flat side. The flat side, indicated at :7, is at the back of the casing. By having the other parts of the casing corrugated an extensive surface for the radiationof heat is provided. A top plate 8 is mounted on the body portion of the attachment and has an opening 9 therein adapted to be closed by the lid L of the stove S, this lid being removed from the openings in the top of the stove and placed on the top 8. The top plate 8 also has an extension 10 corresponding with the extension 3 and fitted therein is a pipe 11 the lower end of which is adapted to engage the collar 5. This pipe has a flange 12 which extends downwardly on to a collar 13 extending upwardly from the back portion of the plate 8 where it communicates with the heating chamber defined by the body portion 6. A damper 14: may be arranged in the branch pipe 12.

The plate 1 and the plate 8 are each formed with a continuous flange 15 which is waved or corrugated so as to fit snugly against the adjacent corrugated portion of the body 6. The flange on the plate 8 is lo cated on the lower surface of said plate while the flange 15 on the plate 1 is arranged on the upper surface thereof. Bolts 16 are extended downwardly through the plates 8 and 1 and through the top key of the stove, these bolts being spiked in any suitable manner, as by means of nuts 17 so as to bind all of the parts together tightly.

With the attachment thus located it will be apparent that when fuel is burned in the stove the hot gases will rise into the easing 6 and heat it to a high temperature. Thus an extensive radiating surface will be provided which will enable the ordinary cooking or laundry stove to be used as an eflicient heater. In warm weather, when there is no need of using the attachment, the same can be disconnected readily by removing the bolts 16 after which the several parts can be separated and storedaway for future use.

Attention is called tothe fact that the device is very cheap to manufacture, it can be easily stored, and can be quickly and readily set up for use without requiring the services of a skilled mechanic.

What is claimed is:

A heating attachment including a bottom plate having an opening,a top plate having an opening, an extension on each of said plates, each extension having an opening for the reception of a smoke pipe leading from a stove, the opening in the bottom plate being adapted to register With an opening in the top of a stove to which the attachment is applied and the opening in the top plate being adapted to be closed by a lid removed from a stove top, a corrugated sheet of metal bent to provide four sides of the heating attachment, said sheet being interposed between the top and bottom plates, ribs on said plates lapping the corrugated sheet for holding it against lateral displacement relative to the top and bottom plates,

bolts extending through the plates for detachable engagement with 'the'top of a stove to bind the plates upon the corrugated sheet and to hold the attachment to a stove top, and a pipe connection between the smoke pipe and the top plate and opening into the space defined by the top and bottom plates of the corrugated sheet.

In testimony that I claim the foregoing as my own, I have hereto affixed my signature.

CHARLES E. LOMBARD.
