IMPROVEMENT IN GRATE-BARS.

Specification forming part ofLetteIs Patent No. 164,401, datc d June 15, 1875; application filed September 24, 1874.

To all whom it may concern:

Be it known that I, JAMES A. SINCLAIR, of Bridgeport, county of Belmont and State pgfOhio, have in vented Improvements in Gratears.

The following description, taken in connection with the accompanying plate of drawings hereinafter referred to, forms a full and exact specification, wherein are set forth the nature and principles of the invention, by which the same may be distinguished from others of a similar class, together with such parts thereof as are claimed as new and are desired to be secured by Letters Patent of the United States.

My invention relates to that class of grates in which the bars are made to reciprocate in reverse directions and the nature thereof consists in certain improvements in the details of the construction of the same, and novel combinations of the parts thereof, hereinafter shown and described.

In the accompanying plate of drawings, in which corresponding parts are illustrated by similar letters, Figure l is a top view. Fig. 2 illustrates in detail one of the bars. Fig. 3 is a view of the operatinglever.

A designates the grate, which is arranged, in the ordinary manner, over the ash-box, and is provided with projections b, which. form a series of slots, 0, in which are placed the bars d. The said bars are of the form clearly shown in Fig. 2, and are provided with upwardly-projecting lugs, having intervals between them, which shield the bar from the intense heat. The said bar is also provided with projections d, the under sides of which may be either parallel with the top of the bar or at an angle therewith. In the latter case the movement of the bar will be not only in the horizontal direction, but also in the vertical plane. The end of the said bar is provided with a projecting lug, g, of proper size to fit the apertures in the operating-lever.

The operating-lever It consists of a plate provided with apertures 70, and having a handle, m. The lugs g are inserted in the apertures k, and the handle m is moved backward and forward. This movement causes the bars on each side of the handle to reciprocate in reverse directions alternately, and effects the removal of the ashes and clinkers with the greatest facility.

Bars of this construction can be placed on the same bearing as that occupied by common bars without change of construction, and have about twenty-five per cent. more air-space than the common bars.

Having thus described the construction and operation of myinvention, Iclaim and desire to secure by Letters Patent of the United States The bars, having bearings d and projecting lugs g, in combination with the operating-lever h, having a handle, m, and aperture 70, into which the lugs g are inserted, as and for the purposes described.

In testimony that I claim the foregoing, I have hereunto set my hand this 6th day of July, 1874.

JAS. A. SINCLAIR.
