IMPROVEMENT IN FURNACE-GRATES.
Specification forming part of Letters Patent No. 135,390, dated January 28, 1873.
To all whom it may concern:
Be it known that l, TEEODOR VON BOLZANO, of Schlan, in the Kingdom of Bohemia, Empire of Austria, have invented a new and useful Improvement in. Fire-Gratos 5 and I do hereby declare the following to be a full, clear, and exact description thereof, which will enable those skilled in the art to make and use the same, reference being had to the accompanying drawing forming part of this specilication, in which drawing- Figure l represents a longitudinal vertical section of my invention. Fig. 2 is a plan or top view of the same partly in section.
Similar letters indicate corresponding parts.
This invention relates to a grate which is intended particularly for burning small coal. My invention consists in the combination of a feed-box with a grate composed of two or more tiers, said feed-box being hungon gudgeons above the other tier of grate-bars, and extending clear across the same in suoli a manner that when the feed-box is filled with coal and then turned on its gudgeons, the coal is evenly spread over the surface of the upper tiers of grate-bars, and at the same time the entrance of cold air is prevented; further, in the arrangement of rods which are actuated by hand-levers, and which engage with the al ternate grate-bars in each of the upper tiers, in such a manner that by actuating said handlevers, the alternate grate-bars in each tier are raised and then lowered, and thereby the lire is cleared and the coals are caused to slide down gradually and uniformly until they reach the lowest or horizontal grate, where they are finally consumed, also, in the a-rrangement of apertures between the several tiers of grate-bars, for the purpose of stirring the lire without materially reducing the temperature in the lire-chamber.
In the drawing, the letters A B C designate three sets or tiers of grate-bars, which are arranged one above the other, the lowest tier or set being placed in a horizontal position, while the other tiers B and A are placed in inclined positions. The inclinations to be given to these tiers may be varied according to the nature of the fuel to be burned 5 but if small coal is to be burned, I have found that an inclination of ten degrees for the lowest tier B, and an inclination of fifteen degrees for the upper tier A, give a good result. I do not wish to confine myself to any precise angle or inclination to be given to the tiers. The grate-bars b b', which constitute the tier B, are supported at or near their centers by a traverse, c, and the bars bl are firmly held in position by a plate, d, which extends across their upper ends and by lips e, which catch under a shoulder of the traverse c. The grate-bars b are provided at their upper ends with forks f, which catch over a rod, g. The ends ot' this rod are bent out at right angles, and they swing on pivots h secured in the side walls of the grate. One of said bent ends is elongated so as to form a lever, i. (See Fig. 1.) The grate-bars b and b alternatewith each other, and by actuating the lever t' the alternate bars b are raised and lowered, and thereby the tire can be cleaned and the fuel is caused to slide down gradually to the next tier below. The tierA is composed ofalternatin g grate-bars a a', Which are arranged similar to the bars b b', respectively, a lever, j, being provided, which connects with a rod, k, for the purpose of raising and lowering the bars a. The horizontal grate C is made in sections, each section being so arranged that it can be drawn, out with a suitable poker, for the purpose of dumping the ashes or cinders which accumulate on this part of my grate. Over the front end of the upper tier A of grate-bars is situated the feedbox D, which swings on gudgeons m, and which, when at rest, bears on the upper edge vof the front plate E of the furnace. From the rear edge ofthe box extends a lip, a, which bears against the abutting-plate F. A handle, q, serves to turn the feed-box on its gudgeons for the purpose of dumping its contents. Said feed-box extends across the entire width ot' the grate, and when its contents are dumped, they are spread evenly over the surface of the grate. In the front plateE are loop-holes, through which the ijre can be inspected without admitting an injurious amount of cold air. Below the front plate E is an aperture, o, for the purpose ot' stirring the fire, and similar apertures o1 o2 are left beneath the lower ends of the tiers A B, so that the fuel can be prevented from clogging.
It will be observed that neither during the operation of feeding in fresh fuel nor duringthe operation of stirring the tire a diminution 2. The arrangement ot' transverse rods g, which are actuated by a hand-lever7 and engage with the alternate grate-bars, substantially in the manner described.
3. The grates A B O, earch constructed and arranged in respect to euch other, as herein shown and described, in combination with the openings o 01 o2, and levers i andj, and transverse rods 7c and g, substantially as set forth.
