Description

PATENT FFIC.
CHARLES TOOPE, OF NEW YORK, N. Y.
IMPROVEMENT IN FURNACE GRATE-BARS.
Specification forming part of Letters Patent No. 158,757, dated January 12, 1875; application filed December 17, 1874.
To all whom it may concern:
Be it known that I, CHARLES To .PE, of the city, county, and State of New York, have invented a certain new and useful Improvement in Furnace Grate-Bars, of which the following is a specification:
This invention is illustrated in the accompanying drawing, in which Figure 1 represents a plan or top View. Fig. 2 is a longitudinal section.
Similar letters indicate corresponding parts.
This invention consists in a grate-bar composed of two side flanges, which are connected by a series of corrugated traverses at the top, and by two or more similar corrugated traverses below, the upper traverses being close together, so as to form a good and even surface for the fuel without preventing the air to pass, in such a manner that a grate-bar is obtained which is capable of expandingand contracting without the liability of cracking.
In the drawing, the letter A designates my grate-bar, which is composed of two side flanges, a a, connected at the top by a series of traverses, b b, and below by two or more traverses, c c. All these traverses are corrugated, as shown in Fig. 1 of the drawing, so that the gratebar can freely expand or 'contract without danger of cracking. The upper traverses, b b, are close together, leaving narrow air-spaces between them, so that they present an even surface for the fuel without obstructing the passage of the air to the fire. The lower traverses, c c, simplyserve to steady the side flanges, and to retain them in the proper relation toward each other. On the outer surfacesof the side flanges, aa, are formed a series of lugs, ef, the lugs e on one side being situated opposite the spaces between the lugs f on the opposite side. In the middle are two lugs, e e, which are situated close together, leaving a space which is opposite to the middle lug, f, on the opposite side, so that when two grate-bars are placed side by sidethe middle lug, f, of one bar will catch between the lugs e e of the adjoining bar, and if the end support of one bar should burn off, said bar will be sustained in the proper position by the adjoining bars. At the same time the lugs e f of one bar bear against the side flanges of the adjoining bars, and thereby all the bars are firmly retained in position, and the side flanges are prevented from warping. The front end, g, of each bar is made inclined, with a flat bottom surface, and a sharp edge, h, the front end of the bar being connected with the first corrugated traverse by corrugated ribs i, which run in the direction of the side flanges, a a, so that the introduction of the fuel is facilitated, and that the fire-bar or poker can be readily inserted.-
Bythese means a grate-baris obtained which can be made comparatively light, which is not liable to warp or to crack, and which allows the air to pass freely to the fire, while the currents of air passing up between the corrugated traverses and the side flanges serve to keep the same comparatively cool, so as to prevent them from burning.
What I claim as new, and desire to secure by Letters Patent, is-
l. The combination, in a grate-bar for furnaces, of the side flanges, a a, the upper series of corrugated traverses, b b, and the lower series of corrugated traverses, c c, for steadying and strengthening the side flanges, substantially as described, and for the purpose specified.
2. The combination, in a furnace grate-bar, of the side flanges, a a, corrugated traverses b b, and the inclined front end, q, connected with the first traverse b by means of the longitudinal ribs i, substantially as described, and for the purpose specified.
In testimony that I claim the foregoing I have hereunto set my hand this 12th day of December, 1874.
, CHARLES TOOPE. Witnesses:
