CHECK-DRAFT DAMPER FOR STOVES AND RANGES.

SPECIFICATION forming part of Letters Patent No. 230,832, dated August 3, 1880.

Application filed May 31, 1880. (No model.)

To all whom it may concern Be it known that I, VVILLIAM A. SPIcEE, of the city and county of Providence, and State of Rhode Island, have invented a new and useful Improvement in Check-Draft Dampers for Stoves and Ranges; and I hereby declare that the following is a full, clear, and exact description of the same reference being had to the accompanying drawings, forming part of this specification.

This invention has reference to an improvement in the construction of the collars connectin g the fines of stoves and ranges with the pipe by which the products of combustion are carried to the chimney.

Theobject of the invention is to simplify the construction of the collar and provide the same with a damper or adjustable air-inlet.

The invention consists in the peculiar construction of the collarprovided with inlet-openings, and of a sliding plate, one end of which is provided with a thumb-piece and the other with a deflector, which, when the damper is closed, forms part of the collar.

Figure 1 is a top viewof a part of a stove or range provided with myimproved collar and draft-regulator. Fig. 2 is a sectional view of the top plate of a stove or range, the draftregulator, the collar, and the slide.

In the drawings, A represents apart of the top plate of a stove or range. B is the line through which the products of combustion are discharged. (J represents the collar by which the stove-pipe D is connected with the stove or range.

0 represents a flat side provided with the thumb-piecef. It is shown in Fig.1,in broken lines, as drawn out so as to close the air-inlets and open wide the draft-flue B, and in both figures, in solid lines, in theposition when the air-inlets are open and the draft-flue is partly closed. The damper 6 therefore performs two functions. When the air-inlets are opened by sliding the damper e inward the draft-flue is contracted, and the draft is thus diminished by the admission of the airand by the contraction of the draft-flue. When, now, the damper eis drawn out the draftflue is opened the full area and the air-inlet is closed.

9 is the collar uniting the stove-pipe D with the flue B, and g g are the air-inlet openings. Such collars are usually secured to the stove or range by placing the same over a projecting rim surrounding the fine-outletin the plate. I prefer to secure the same more firmly, and provide a portion of the collar, preferably the portion between the air-inlet openings, with the hooked end h, which is entered into a hole in the stove-plate, and then secure the other end by means of the bolt 1', so that the collar is now firmly secured to the plate A.

The damper e is provided with the slit 7c, the end h is passed through the slit, and thus the damper is secured and a central guide is provided by which the liability of \vedging the sliding damper is prevented and a regular smooth movement is secured. This feature is important in a stove, as dampers have to be frequently moved. When the cook is in a hurry and not often blessed with patience, adamper that will stick or bind will meet with rough usage and frequently with utter destruction.

Z l are theinclined segmental portions of the damper e, which enter the openings g g. When the air-inlet is to be closed, as these parts 1 Z are vertical and preferably inclined like the sides of the collar, they form deflectors, by which the inrushing air is directed upward to check the draft.

By this arrangement great economy in construction is secured over similar dampers as heretofore constructed, in which an extra airbox had to be connected with the flue, into which air was admitted when the damper closed the flue or contracted the area of the same, While in my improved device the air is admitted through the sides of the collar when the damper is pushed inward, and no box or other device is required. The whole is simply secured to the top of a plain plate, as shown, and the air is directed at once into the stovepipe, quickly checking the draft and flowing in above the contracted flue, and not, as has been the case heretofore, below the contraction of the flue, being cheaper, better, and more effective.

This attachment can be secured to the back of the stove or range, when desired, without tions Z Z, arranged to regulate the air-inlet and the flue-opening, as described.

3. The combination, with the plate A, the flue B, and collar 0, provided with openings, of the sliding damper 0, provided with the slit k, constructed to control the draft by increasing or decreasing the area of the flue and open- 20 ing or closing the air-inlet, as described.
