| Most of the patents prior to 1836 were lost in the Dec. 1836 fire. Only about 2,000 of the almost 10,000 documents were recovered. Little is known about this patent. There are no patent drawings available. This patent is in the database for reference only.
"For a Cooking Stove for burning Lehigh, and other hard coal; Cornelius Schermerhorn, New York, June 23.
Judging from the drawing and description, we should think this stove well adapted to its purpose. At all events, it is distinctive in its character, the structure of the stove, and the management of the fire, differing essentially from every other which we have seen.
The body of the stove is a rectangular iron box, closing in front with folding doors. This box contains a sliding grate, or furnace. In the drawing accompanying the specification, the grate is repre
sented in the form of the ordinary Lehigh coal grate, with open bars in front. The box in which the grate is contained, is in length and height just sufficient to receive it, but in depth, from front to back, about three times that of the grate. A bar, or rod, projects forward, by means of which the grate, which slides upon ledges, may be drawn forward, or pushed towards the back of the containing box. The top of the box, in front, is perforated to receive boilers, &c. under which the grate may be drawn, whilst at the same time roasting may be effected in front of it. The back half of the box is surmounted by an arched oven, formed of double plates, to allow a passage to the escape pipe. There are sliding dampers, and other appendages, which appear to be ingeniously contrived and likely to operate well, but which we shall not attempt to describe.
The claims are to the sliding furnace acting directly on the boilers, and all parts of the oven; and likewise the ventilators, preventing a too intense heat upon the bottom of the oven plate; also the portable slide, or damper, and the construction of the double flue."
