IMPROVEMENT IN DRAFT-DEFLECTING PLATES IN COOKING-STOVES.

Specification forming part of Letters Patent No. 210,440, dated December 3, 1878;4 application filed I March 4, 1878.

' the city of Troy, county of Rensselaer, and

State ofNew York, have invented an Improved Method of Operating a Draft-Deflecting Plate within the Draft-Chamber of a Cooking-Stove, of which the following is a specification:

My invention relates to a manner of constructing a hinged draft-deilecting plate and a slide-damper, so that the latter shall operate the former to open and close the space in the draft-chamber of a cooking-stove, between the edge of the grate and the inside of the stove-wall, at the front.

The object of the invention is to have the slide-damper andl swin ging plate cooperate, so that when the damper is opened it will in opening force the detlecting-plate to swing up, 4so as to close the draft-space between the edge of the grate and the inside of the front wall of the stove, and thus force the entering airdraft to pass up through the bottom of the grate, and when the damper is closed will allow the deilecting-plate to swing down, so that the open clinker-cleaning space at the bottom ofthe front wall of the fire-chamber will be in communication with the draft-chamber area below.

My invention consists in arranging a hinged draft-deflecting plate within the draft-chamber of a cooking-stove, so that it will freely swing up and down, and between the wall and front edge of the grate, by means of an upturned and curved projecting foot formed upon the end of the sliding draft-damper plate, whose curved surface upon its inner side engages the end of the hinged swinging plate, and as the damper-plate is moved laterally it forces the plate to swing up or allows it to drop down.

In the accompanying drawing there are three iigures illustratingmy invention.

Figure l shows a vert-ical section of the firechamber of a cooking-stove, illustrating the hinged swinging plate in contact with the proj ectin g curved foot, with the plate partly turned up. Fig. 2 shows a rear view of the swin ging plate.

The various parts of the device and the stove to which the same are applied are designated as follows by letter-reference: J J, the stovejambs; A, the draft-chamber below the grate; G G, the part ofthe grate in position 5 I), the hinged plate; D', the damper-handle; D, the sliding damper-plate; O O, the draft-damper openings 5 F, the projecting curved foot, which engages the edge of the hinged plate l) at E. T T designate the journals for the latter to swing in. H denotes the hearth 5 S, a portion of the fire-chamber front wall, and R the front wall of the stove, to which, on its inner side, the swinging plate is hinged.

The operation of the combination is as follows: The damper-plate D is of the usual construction, and arranged, in the usual manner, to slide horizontally upon the inside of the front stove-wall, the latter having apertures O O, to correspond with the apertures formed in the damper-plate, and which when opposite allows all the draft to enter the opening; but when moved Ahorizontally until the blank surfaces on the plate come opposite the openings in the stove-wall it closes the draft. The foot F, formed upon the end of the damperplate D, engages the end ofthe swinging plate at E, so that when the former is moved horizontally to open the damperapertures the plate swings up, so as to cause the draft to enter the grate at the bottom, instead of allow-l ing part of it to enter the clinker-cleaning opening at the front and bottom of the iirechamber wall. When the draft-damper is moved horizontally to close the damper, then the swinging plate, no longer held up by the curved foot under the influence of gravity, falls down to open the space between the front of the grate and the inside of the stove front wall, and to which the plate is hinged.

While I have shown the curved foot as formed upon the damper-plate, it is plain that it may be formed upon the hinged plate, and so as to engage a projecting cam-surface upon the sliding draft-plate, and thus arranged to produce the same result.

Vhile I have illustrated the damperplate with its projected curved and upturned foot arranged upon the front stove-wall, it may be formed upon the hearth with the foot so curved and projected upward and rearward as to engage the end of the swin ging plate in the same manner and operate in the saine way.

Having thus described my invention, what up to close the space between the grate and front stove-Wall when the draft-damper is opened, and releases it to swing down when the draft-damper is closed, as shown and described.
