Stove Grate.

IMPROVEMENT iN STOVE-GRATES.

Specification forming part of Letters Patent No. 123,588, dated February 13, 1872.

Specification describing certain Improvements in Stove-Grrates,77 invented by J AMES SPEAR, 1116 Market street, Philadelphia, Pennsylvania.

My invention relates to improvements upon the grate known to the trade as the pirotbar and drop-grate; and consists in making one part of the grate slide beneath the other part, so that the iirc can be dumped into the ash-pan Without drawing the grate outside of the base, or Without its interfering in any way with the removal of the ash-drawer.

Referring to the drawing, Figure l is a plan of the ring. Fig. 2 is a plan ofthe grate complete. Fig. 3 is a section on the linexy. Fig. 4 is a section on line v w.

I construct the gra-te first, With the rim or band A, with a notched edge, carried by a depressed pivot-ba-r, B, and turning upon the center pivot b. On each side of the ring is cast a groove or slide, G, upon which one portion of the grate D slides beneath the other part, E. rIhe part E is i'n the form of a semicircle, and rests upon the ring A by the three lugs e, two of which are secured by screws e". The part D, somewhat thinner, is also in the form ot a semicircle. It slides upon the bear ings C close above the pivot-bar B and beneath the grate'E and ring A. It is operated by the rod g', which passes through ahole in the base oi' the stove to the handle G.

rEhe advantages of my grate over the dropgrate are that it does not obstruct the removal of the ash-drawer, and permits thev use of a deeper one than can be used in the present stove bases, so that more ashes can be carried out at a time. The slides D can be pulled out a sufficient distance to drop a panful of ashes at a time, without the danger ot' filling it too full and spilling the ashes in the base, with the trouble and dust consequent therefrom.

Again, I am aware that sliding bars are drawn out from iat grates, and grates are made to slide out from under the re; but these must be drawn outside of the stove-casing, thus permitting dust and ashes to fall on the floor.

My improved grate can be worked inside of a base, which is small and elegant in design, and can be adapted to cylindenstoves now in nsewithout the necessity of making a new base.

I do not claim the dumping of the fire by the drawing out of a bottom slide from beneath the fire-pot or ring of the grate. My invention consists in drawing out one portion of the grate under the other part, so as to avoid the drawing out of' the Slide beyond the outer edge of the grate or outside of the outer wall or' the stove, and at the same time providing a large opening through the grate. Slides otherwise constructed necessitate'the enlargement of the base, or the bottom must be drawn outside the Wall of the store.

l. A horizontal stovegrate, constructed with an openingthrough one side, as shown, covered by a slidin g section, D, which slides under the other part E, as and for the purpose herein described.

2. rlhe construction of the ring A with pivotbar B, in combination with a slide, C, for the purpose herein set forth.

3.- The combination of the ring A, pivot-bar B, and grate E with the sliding grate D, as herein described.
