Umreo STATES ELIE MONEUSE, OF NEW YORK, N. Y.

FlRE-GRATE.

SPECIFICATION forming part of Letters Patent No. 228,376, dated June 1, 1880.

Application filed March 24, 1880. (No model.)

To all whom it may concern Be it known that I, ELIE MoNEUsE, of the city, county, and State of New York, have invented a new and useful Improvement in Fire- Grates, which invention is fully set forth in the following speci fication, reference being had to the accompanying drawings, in which- Figure 1 represents a front view of my grate applied to a furnace. Fig. 2 is a vertical crosssection thereof. Fig. 3 is a vertical longitudinal section of the same.

Similar letters indicate corresponding parts.

My invention is adapted to grates for any useful purpose; and it consists in the combination of a revolving grate having a segmental or semicircular cross section and a latch for retaining the grate in its normal position, so that the grate may be dumped and returned to an upper or normal position without difficulty. The latch allows the grate to be oscillated or shaken on its axis, and, moreover, is self-acting, the latch being arranged to engage a radial arm projecting from the grate-shaft, and having two beveled ears, between which the radial arm is permitted to move, and which allow such arm to take its place between them when the grate is moved to an upper position.

In the drawings, the letter A designates a portion of a furnace or stove, forming bearings for the shaft B of the grate G. The shaft B projects through the front of the stove, and is squared at the outer end to receive a key for revolving the grate.

In cross-section the grate 0 forms a segment of a circle, and it is preferably made semicircular, as shown in Fig. 2. In its normal position the grate 0 stands above its axis and presents a convex surface to the fire-pot of the stove.

In stoves containing the ordinary flat revolving grate it is necessary to remove the ashes from the ash-pit, after dumping the same, before the grate can conveniently be returned to an upper or normal position, and since the ashes are usually dumped in a burning state it is common to leave the whole untouched, after (lumping, until the ashes cool off. The result of this practice is that the grate-bars burn out in a short time.

It will be readily perceived that by the shape of the grate 0 it is adapted to be overturned for the purpose of dumping the ashes and immediately returned to an upper position.

The letter D designates a lat-ch used for the purpose of retaining the grate O in its upper or normal positionh This latch is hung on a pivot, c, at one end, and acts on a radial arm, F, projecting from the grate-shaft B, both the latch and arm being situated on the front of the stove, where the latter is provided with a rest, g, for the free end of the latch. On the latch D are two ears, h, which are beveled on their outer edges, their inner edges being straight.

When the grate G is turned from a lower to an upper position the radial arm F strikes the beveled edge of either of the ears h, according to the direction of rotation of the grate, and by this means the latch is raised, so that the radial arm may take its place between the two cars. The space between the ears It allows a movement of the radial arm F, and it follows that the grate C may be oscillated or shaken on its axis.

The letter I designates the bars of the grate C. These bars are mounted on the shaft B, and held or fastened together by a tie-rod,j, passing through lugs projecting inwardly from the bars. By this arrangement the bars I are rendered removable, and may be respectively replaced, when burned out, by a new bar.

On one side of the bars I are spurs I, while on the opposite side thereof are sockets which correspond to and register with the spurs, so that when the bars are put together such spurs and sockets interlock with each other.

In this manner the bars I are held against longitudinal displacement, and the joint between them is improved.

In this example the bars I are independent of each other throughout the grate; but, if desired, the bars intermediate of the two end bars may be cast all in one piece. Said two end bars are fastened to the grate-shaft'by pins m.

What I claim as new, and desire to secure by Letters Patent, is-
