Patented June 30,. 1838- UNITED STATES PATENT oEEIoE.
JOSIAH DUTGHER, OF NEW YORK, N. Y.
MODE OF RAISING AND I IOWERING THE GRATES OF STOVES.
Specification of Letters Patent No. 822, dated June 30, 1838.
To all whom it may concern Be it known that I, JOSIAH DUTCHER, of the city of New York, in the county and State of New York, have invented an Improvement in the Mode of Raising and Lowering the Grates of Stoves for the Burning of Coal or other Fuel; and I do hereby declare that the following is a full and exact description thereof.
The object in view is to graduate the height of the grate so as to adapt its position to the burning of different quantities of fuel, and to cause it to approach near to,
or be removed from, such cooking utensils as may be placed above it.
The apparatus by means of which I raise, or lower the grate consists of two cams upon a shaft which crosses the stove under the grate each end of the grate resting upon one of these cams, so that by turning the shaft by means of a winch, the desired effect may be produced. The grate may be used in stoves of various kinds, either with or without ovens, the particular c0nstruction of the stoves being so varied as to adapt it to the raising grate.
The accompanying drawing represents a vertical section of a stove, from front to back, having an oven behind the grate, with flues surrounding it, as in many other stoves.
A, is one of the cams for raising the grate; this cam I make in the form'of one quarter of an oval; a, being the center, or shaft upon which it turns. By revolving this shaft it may be made to rest upon the points I), or 0, the length of the quadrant being such as is equal to the greatest rise required, and these different elevations bein fuI purposes. The bottom edge 01, of one end of the stove is shown as resting on one all that will be found requisite for useof the flat sides of the cam; e, e, are the I sented inthe drawing, the draft passes in.
this direction, but when it is raised it closes the flue g, g, and passes around the flue j, j, at each end of, and under the oven.
What I claim as my invention is The raising and lowering of the. grate by means of cams upon a revolvin shaft, which cams are one quarter of an ellipsis,ior oval, and operates in the manner herein described. i
It is distinctly understood that I do not claim to be the first who has made a grate to raise and lower, this having been done by racks and pinions; chains and weights, and in other modes.
I claim only the manner of effecting this Witnesses:
