GRATE.

SPECIFICATION forming part of Letters Patent'No. 329,375, dated October 27, 1885.

Application filed March 3, 1885.

To @ZZ whom it may concern.-

Be it known that I, .IAMEs DUFFY, of Quincy, in the county of Adams and State of Illinois, have invented a new and useful Improvement in Grates; and I do hereby declare that the following is a full, clear, and exact description of the same.

My invention relates to grates for cooking stoves, and is designed to render the grates more durable.

It consists of a certain construction, hereinafter fully described in principle and` detail, whereby the grate is made, as a whole or in part, reversible, and, while capable of being moved longitudinally for shaking, may be used with either side uppermost, and at the same time may be held securely in position with either side up.

My improved grate is shown in the accompanying drawings, in which Figure l is a plan view of the grate as it appears in position within the stove. Fig. 2 is a transverse section atross the supporting-rod. Fig. 3 is a perspective View of one of the grate-sections. Fig. 4 is a detail view showing how the sections are fitted into each other.

The grate is composed of sections, of which ctare uniform in shape and size. At the ends are sections b, 'having central bosses ou one side only, and provided with studs c c, the purpose of which is hereinafter explained. Every one of these sections forms a bar of the grate. The sections c have an enlargement on each side at the center. On one side this is recessed, as shown at d, and on the other side the projection d is fitted to enter the re cess of the contiguous section. All the sections have central transverse holes for the admission of the bar or rod B, on which they are supported and turn, and they are placed on this bar or rod with the contiguous projections interlocking throughout, so that all the sections are held together and form a solid grate, as if cast in one piece. At the same time any section may be removed and replaced by another in case of wear or breakage. The sections are held from turning on the rod or bar by the shape of the bar and holes in the sections, and all turn with the bar. It will be observed that the upper and lower faces of the sections are alike in shape, so that either face of the grate may be used. The sections should be held in close contact with each other, and this may be done in any convenient way. I have shown one of many which may be used. This consists in threading one end of the bar or rod and turning on a nut, f, to press against the section at one end. The 'other end section bears against another nut or projection, g, on the other end of the bar or rod. Sufficient space is left in the frame D of the stove for the necessary endwise movement of the grate. On one end of this frame are pockets 7c 7c, one on each side of the central rod or bar on which the grate turns, in line with the studs c c, and adapted to receive these studs when the grate is pushed endwise toward the pockets. Vhen thus pushed into the pockets, the studsc c hold the grate and prevent it from turning, whichever side of the grate be uppermost; but when the grate is drawn back the studs are withdrawn from the pockets and the grate may be turned. Ordinary projections, O', on the end of the grate opposite the pockets serve to ll the space left for the endwise movement of the grate.

Any ordinary means may be used for turning the main pivoting bar or rod of the grate.

'Io dump the ashes and cinders it is necessary only to draw the grate endwise until the studs leave the pockets, when the grate may be turned over and shoved back to bring the studs again into the pockets.

I claim as my invention- 1. In combination with a frame having pockets at one end, a reversible grate movable endwise in its bearings, composed of sections alike on both sides, a central pivoted shaft supporting said sections, which turn therewith, and studs on the end section of the grate, said studs engaging with the pockets on the frame, whereby the grate is prevented from tilting, substantially as described.

2. A grate composed of sections alike on both sides, having enlarged central portions, said central portions having horizontal projections d upon one side and vertical projections d upon the other, whereby said sections are caused to interlock with each other, and a central opening through each for the tie bar or rod pivoted on the grate-frame, combined with said bar or rod, substantially as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.

JAMES DUFFY.
