GRATE.

SPECIFICATION forming part of Letters Patent No. 288,864, dated November 20, 1883.

Application filed November Q8, 1881. (No model.)

To all whom it may concern: Y

Be it known that I, THoMAs Bossen, a citizen of the United States. residing at Bellaire, in the county of Belmont and State of Ohio, have invented certain new and useful Improvements in Grates and GrateStoves; and I do hereby declare that the following is a full, clear, and exact description of theinvention, which will enable others skilled in the art to which it appertains to make and use the same.

My invention relates to improvements in gra-tes for use in fire-places, open-front stoves, and other similar heating devices, and is particularly adapted to such heating devices above specified as are provided with a rack and side tile lining.

It consists in a vibrating grate composed of horizontal and transverse bars firmly secured together and supported on aframe of peculiar form, the said frame having its ends and rear parts arranged to support the tiles which line the fireplace.

It consists, further, in the construction, combination, and arrangement of the several parts hereinafter fully described, and pointed out in the claim.

In the drawings, forming apart of this application, I have shown myimprovements applied to an open-front stove, for the reason that in such application the invention can be more conveniently'illustrated and described than if applied to an ordinary fireplace formed in a` chimnevbreast. 4

In the said drawings, Figure l is a front elevation of an open-front stove having a part of the front grating brokenv away to show the edge of the grate and a portion of the supporting-frame. Fig. 2 is a vertical section on line a* fr, Fig. l, showing the grate and supportingframe in crosssection. Fig. 3 is a crosssection on line y y, Fig. l, showing a plan of the grate with its longitudinal bars eX- tended under the tiles. Fig. 4 is a vertical section on line a: x, Fig. 2, showing the grate and frame in longitudinal sec-tion and their relative positions to the tiles. Fig. isaplan of the grate and supporting-frame removed from the fireplace. Fig. 6 is a detail plan Fig. 7 is a detail plan view of the vibrating grate, and Fig. S is a cross-section of the supporting-frame.

The supporting-frame B is made to fit snugly between the end plates of the casing G and bar of the lire-place front A. Its end bars, B3, rest on projections or supports G ou the end plates of the casing. The frame is open at its front side, the opening being closed by the bottom bar of the front. The small portions B2 are turned inwardly, as shown. Crossbars B5 connect the inner ends of theportions B2 and the.f rear bar, Bi. These cross-,bars have their upper edges cut down, so as tb depress their upper surface below the upper surface of frame B. The depression is equal to the vertical thickness of the longitudinal bars of the grate, so that the upper 'faces of said bars, when placed on the cross-bars B5, will be iiush with the top of the said frame.

The vibrating grate B is composed of the longitudinal bars c and the transverse rakers or bars c. The rakers a. being placed on top of the bars a., extend above the plane of the top of the frame B. Their ends therefore extend upward close to the side of the rear tile, E. These transverse rakers extend up into the body of re or ashes in the fire-place, and when moved rake the said ashes down into the ashboX. By the position of their ends in close proximitj,r to the rear tile, they preserve the grate steadily in place in the vibrating movements thereof. One of the longitudinal bars of the grate is provided with a perforated lug, ai, extended downward, the opening therein being arranged opposite a suitable opening in the lower bar of the fire-front. The 'opening in the lug cl receives the end of the shaker by which the grate is vibrated. One or more of the longitudinal bars a is providedA at its opposite ends with stops ai', so arranged that they will come in contact with the cross-barsv B5 and prevent the grate from be'- ing thrown too far endwise. rIhe tiles which line the back and ends of the fire-place rest on the back bar and end bars of the frame B, covering and preventing the fire from coming in contact with the latter. The' end tile E rests on the rear bar, Bi, and the end tiles E rest on the end bars, B.

The frame B, it will be seen, is almost entirely protected from being burned by the great heat of the fire. The only portions er; posed are the cross-bars B and smallportions between the back plate thereof andthe lower of the ends of the parts B2; but these exposed parts are near the edges, or have an air-space between them and the re, so that there is very little liability of being injured. The grate may be slipped endwise till one of the stops a strike the cross-bar B5. This will bringl the opposite end of the grate flush with the inner face of the tile E', and this end can then be lifted upward` and the grate taken out of the stove. It will be seen that thus the old grate may be easily removed and a new one as easily put in. The ends of the bars a eX- tend under the tiles E', and it is impossible Vfor the grate to get clogged by stone or other hard substances often found in coal.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

The combination, with the frame B, having cross-bars B5, depressed below the upper sur- 2o THOMAS ROSSER.
