lMPROVEWENT IN STOVE-DAMPERS.

Specication forming part of Letters Patent No. 128,85),-datcd July 9, 1872.

Specification describing a certain Improvement in Dampers for Stoves, invented by AN= DREW Cowan, of Scranton, in the county of' Luzerne and State of Pennsylvania.

This invention relates 'to the combination of a swinging damper, situated Within a stove,- and having a handle that projects thron gh the side of the stove and works in a slot therein7 with a slide which serves both to keep the damper in place when raised, and to close the said slot when the damper is either raised or lowered, said slide moving with lhe handle when in motion.

Figure 1 is a transverse vertical section 5 Fig. 2, a perspective view; and Fig. 3, a side elevation.

A is the damper, aforesaid, the same' being placed, in this instance, under the grate a ot' a cooking-stove, and at the front end of the lower line of the same, and hung so as to swing and open and close the hole in the partition c. The handle e otl the damper extends through a curved slot, c', in the side of the stove, which slot allows the handle the play necessary to raise and lower the damper, being enlarged at its ends to hold the handle when the damper is either raised or lowered. A slide, m, is fastened to the side of the stove by means of a l pin passing through a slot in the slide. This slide is curved at the edge r, next the handle e, in the same arc as the slot i. It has a recess, n, which the handle e occupies when the damper is lowered, and shoulder 0, which can be shoved under the handle when raised, to assist in holding it. When the slide is thus shoved endwise, it covers the slot i and prevents dust from escaping thereat.

To lower the damper, the slide must be moved backward so as to clear the handle, and the latter, descending through the slot i, enters the recess n, and, striking the slide, moves it so asto close the slot i. NVhen the damper is raised, the handle also moves the slide m, so that the latter does not have to be moved by hand except to close and open the slot i when the damper is raised.

.I claim as my invention- The slide fm, having the recess n, shoulder o, and curved edge r, in combination with the slot c', damper A, and handle c, arranged as described.

ANDREW OOWAN.
