JOHN H. WOOD, OF CHARLESTON, ILLINOIS.

DAM PER-REGU LATOR FOR STOVES.

SPECIFICATION forming part of Letters Patent No. 486,314, dated November 15, 1892.

Application filed February 23, 1892.

To all whom it may concern:

Be it known that I, JOHN H. WOOD, a citizen of the United States, residing at Charleston, in the county of Ooles and State of lllinois, have invented anew and useful Damper- Regulator for Stoves, of which the following is a specification, reference being had to the drawings, and to the letters of reference marked thereon.

' Figure 1 is a side elevation of a stove or range to which I have applied my improvements. Fig. 2 is a vertical longitudinal section of the same. Fig. 3 is a transverse vertical section showing the reservoir-damper open. Fig. t is a similar view showing the damper shut. Fig. 5 is adetail view hereinafter referred to.

My present invention relates to stovedampers.

The improvements consist in applying to a stove, preferably a cooking-stove, a mechism or device so disposed and arranged that Whenever the oven-door is opened the dam per which controls the fines from the stove to the Water-back or reservoir will be closed by the act of opening said oven-door and that when the oven-door is shut after being opened said damper will remain closed, but at the same time free to be operated by the usual handle. It will be understood that when baking the damper leading to the water-back must be closed. Otherwise the heat will not be directed to the space under the oven and the latter will not bake on the bottom. It will also be seen that in order to place any article in the oven for baking the oven-door must necessarily be opened, and this act of opening closes this damper before the baking action takes place.

Referring to the drawings, A represents a stove or range provided with a water-back 0r reservoirB and aflue or fines 0, leading from the stove to the water-back.

D is the damper or dampers, leading from the stove to the water-back and controlling the flue-passages 0, whereby the heatfrom the stove is directed to the water-back or cut off therefrom and thrown down under the flue or air-space beneath the oven. 4

E represents the oven-door, hung upon Serial No. 422,430. (No model.)

hinges F. This door carries a cam, eccentric, or projection G, rigid therewith and moving with the door.

H is a sliding piece or bar adapted to have an endwise movement through a slot made in the side of the stove and suitably arranged in operative relation with the cam G.

I is an elbow-lever pivoted at J to a lug or cars K, rigidly secured to the stove or its lining adjacent to the oven-door E. The lower arm L of the elbow-lever I is pivotally conheated at M with the sliding bar H. The opposite end N of the lever I is projected inwardly and in this instance is given a double-rightangled bend, the extremity of which is free to engage certain hereinafter-described parts. 6 5

D represents dampers covering the flue-passages, before referred to.

O is the rod upon which the dampers D are journaled, and P is the usual damper-operating lever, attached to rod 0 outside the stove.

Q is a projection rigid with the dampersD and rod 0 and projecting out within the vibratory path of the end N of the elbow-lever I, so as to be acted thereon by said lever.

' The opening of the oven-door for the purpose of inserting any article to be baked causes the cam or projection G, moving therewith, to engage the outer end of the sliding bar H and force it inwardly. This inward movement of bar H causes the rocking of the elbow- 8o leverI upon its pivotJ by reason of its pivotal connection M therewith. An upward movement of the inner end N of said lever I ensues, and it comes in contact with the projection Q, secured to the dampers D, and closes them, 8 should they be open, and, if not, the movements of the parts are idle.

When the dampers are closed by my improved dam per-regulator, they remain so until opened by hand by the handle P.

Where the word stove is used throughout the specification it will be understood, also, that a range is meant or any other heat-ing device to which my improvements can be ap plied. It should also be further understood 5 that in speaking of a water-back the usual reservoir of a cooking stove or range is also included.

an operating-piece, a damper controlling the flue-passages to the water-back, and mechanism arranged between the oven-door and the damper for closing the latter upon open- :0 ing. the door, substantially as described.

In testimony whereof I hereunto set my hand this 17th day of February, 1892.

JOHN H. WOOD. Witnesses GEO. A. KRIEG, W. H. WILLCOX.
