DAM PER FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 358,330, dated February 22, 1887.

' Application filed April 30, 1886. Serial No. 200,660. (No model.) i

To all whom it may concern.-v

Be it known that we, ALPHEUS'M. BLAKES- LEY, and DANIEL G. WHITE, citizens of the United States, and residing in the city of Rock Island, in the county of Rock Island and State of Illinois, have jointly invented certain new and useful Improvements in Dampers for Stoves and Ranges, of which the following is a specification.

Our invention is an improvement in dampersordiuarily employed to the exit-flues of stoves and ranges; and it consists in the features of construction and combinations of parts hereinafter fully described, and pointed out in the claims.

In the drawings, Figure l is a perspective view of the rear upper portion of a stove embodying our invention, parts of the plates being broken away to more clearly illustrate Fig. 2 is an inside view of the upper portion of a rear flue-plate with the damper removed. Fig. 3 is a horizontal section. Fig. 4 is a perspective view of the damper detached. Fig. 5 is a vertical cross-section of the upper part of a stove on a line in front of the damper, and Figs. 6 and 7 are views of the rear upper corner of a stove where the damper-handle is located.

Our invention may be applied to all stoves and ranges where the orifice in the exit-fines is capable of being closed by a dampervalve on a line with its handle. For convenience we haveillustratcd it in the drawings, and will describe it in the specification as embodied in an ordinary three-flue stove in which the exit-flue is in the middle of the rear portion.

0 is the oven of an ordinary three-flue stove, its exit-flue having a damper, A,formed from a single casting or piece of metal, of which its valve (1 is adapted by its reanpintle, a',working in the slotted bearing 1) in the side plate B of the exit-flue, and its handle a,working in the slotted bearing 0, in the side plate 0 of the exit-flue, and the bearing 6 in the outer plate of the stove,to open and close the draft-orifice in the exit-flue. The outer end of this damper is provided with a suitable crook, a by which it is actuated.

B G are the side plates of the exit-flue, each having a slot,b c, forming bearings for the damper, and flanges or ribs 1) c b 0" upon their inner faces, upon which the damper-valve rests, respectively, when open or closed.

To the outer face of the flue-plate B is riveted a button, D, itstfree end being provided with a shallow recess, as at d, and adapted to embrace the pintle end,a,of the damper, hold the damper in its slotted flue-plate bearings, and prevent its escape therefrom when adjusted. Upon this side of the rear flue-plate is a stop-lug,b ,to limit the upward movement. of the button.

The outer stove plate, E, has a hole,e,forming the outer bearing for the damper, and beyond which the crook of the damper projects. This hole or bearing is not made at right angles to the outer plate. The metal of the plate is slightly re-enforced in front of the hole, as at e, and the orifice is made on an angle in the direction of the crook on the outer end of the damper when adjusted to the stove.

v The damper is adjusted to the stove by placing it entirely under the top plate and pushing the crook of the handle through the hole in the outer stove-plate until the pintle and bearing-surfaces of the damper fit into their bearings formed on the exit-flue plates, and it is secured in position by dropping the button over the pintle, the button and the rear slotted flue plate together forming a snug bearing for the pintle, and with the bearing on the outer stove-plate serving to retain the damper in close working position.

The advantages of this device are obviously the employment of asingle castingfor the purpose of a damper and avoiding the necessity of having it in two or more pieces and rivet-' ing or otherwise securing them togetherin.

adjusting it to the stove; in dispensing with rivet-sor equivalent means for securing the damper'to the stove-plates, (this ordinarily side of the flue plate or plates, we may rivet construction and increased edeetivenessin operation.

By the peculiar construction of the orifice in the outer plate-that is, elongated in the direction of the crook in the damper when adjusted, with the metal on the plate slightly I reenforced-the crook of the damper may be thrust through it without providing a larger orifice at right angles to the plate than the diameter of the handle, thereby affording a snug bearing for this end of the damper and dispensing with a slot and button or other de 1 vice for holding the damper in close adjusti ment.

Instead of the button attached to the enter it to the top flue'plate of the stove,with its free i end adapted to slide over the pintle end or .1 other bearing-surface of the damper, as shown 1' in Fig. 5, and thus hold the damper in close i adjustment in its bearings and prevent its lateral escape therefrom. IVe may also eniploy in place of the inclined hole in the outer plate an elongated sleigh, as shown in Fig. 6, of about the size of the creek a, and provide a slide,f, to cover a portion of such slot and afford a snug fit for the damper.

e claim as our invention-- 1. In a stove or range,the combinatiomwitli the outer stove-plate and the exit-flue plates, formed with bearings b c c, of the damper A and a pivoted button, D, having a slot to engage the pin'tle of the damper, substantially as set forth.

2. In astove or range, the combination,witl1 lthe outer stove-plate and exit-flue plates formed with bearings b c c, of the damper A, comprising a valve, a pintle, a, and a handle,

i a, of a single casting, and a pivoted button,

D, formed with a slot,substantiall y as set forth.

3. In a stove or rangc,thccombinatiomwith the outer stove plate and exit-flue plates formed with bearings b c e, of the damper A, having a crook, a and a pivoted button, D, constructed and arranged substantially as described.

4. In a stove or range, the combination,with the outer stoveplate and the exit-flue plates, of the damper A, formed with acrook, a, the outer stove-plate having a slot, F, and the slidef, substantially as set forth.
