GRATE.
SPECIFICATION forming part of Letters Patent No. 468,033, dated February 2, 1892.
Application filed March 1 9, l 8 91.
To all whom it nuty concern:
Be it known that I, WILLIAM L. CARTER, a citizen of the United States, residing at Cedar Falls, in the countyof Black Hawk and State of Iowa, haveinvented a new and useful Grate, of which the followingis a specification.
This invention relates to improvements in grates for furnaces, &c.; and the objects in view are to provide a grate of cheap and simple construction that may be easily operated, and which when so operated will thoroughly shake the ashes therefrom into the ash-drawer.
Other objects and advantages of the invention will appear in the following description, and the novel features thereof will be particu larly pointed out in the claims.
Referring to the drawings, Figure. 1 is a perspective of a grate constructed in accordance with my invention. Fig. 2 is a vertical longitudinal section. Fig. 3 is a plan, the grate being removed. Fig. 4c is a bottom plan view of the grate, the same being in detail.
Like numerals of reference indicate like parts in all the figures of the drawings.
1 indicates the ash-pit, into which may be slid the usual ash-drawer, (not shown,) and the same has its rear end rounded and has mounted thereon the cylindrical fire-pot-supporting rin 2.
A cross-bar 3 spans the ash-pit in front of the supporting-ring 2, and upon the same and to the wall of the ash-pit is secured the ring a, the outer edge of which is provided with a series of teeth 5. At intervals upon bearing pins 6, located under the ring 4:, are mounted loose rollers '7. In longitudinallyopposite bearing-brackets 8 there is mounted for rotation in bearings 9, formed therein, a shaft 10, which extends outside the ash-pit, is there provided with an operating-crank 11, and inside the same, under and within the ring 4, is provided with a gear-wheel 12.
The grate proper consists of a cylindrical collar or frame 13, the lower edge of which is toothed,as at let, and the upper edge of which is provided wit-h a flared inclined flange 15,
the inner edge of which extends beyond theinner surface of the cylindrical frame 13 and is provided at intervals with tangentially-disposed ribs 16. The inclined flange 15 loosely fits the fire-pot-supporting ring 2, while the cylindrical frame or collar 13 fits within the Serial No. 385,649. (No model.)
In operation the crank at the front of the ash-pit is rotated, and through the medium of its gear, which engages the lower toothed edge of the grate-frame, said grate-frame is rotated, and in so doing the teeth of the star-wheel of the central shaft of the grate engage the teeth of the grate-ring 4i, and thus said central shaft is rotated and through the medium of its gear transmits motion to the gears of the two side shafts, and in this manner the entire bottom of the grate is revolved, so that a most thorough agitation of the fire may be had and all ashes quickly deposited into the ash-pit. It will be noted that the flange 15, revolving with the grate, being inclined and provided with tangentially disposed ribs, serves to gather and direct the usual wall of ashes that surround the fire to the center of the grate, and from thence into the ash-pit.
Having described my invention, what I claim isl. The combination, with an ash-pit having a toothed ring mounted therein and a shaft rotatably supported and extending under said ring, of a grate-frame having a lower toothed edge,a gear mounted on the shaft and engaging the toothed edge of the frame, a series of shafts rotatably mounted in the frame, gears connecting the corresponding ends of the same, and a gear mounted on one end of one of the shafts and engaging the ring of the ashpit, substantially as specified.
2. The combination, with the ash-pit, the
gear-wheel 12, and also are designed to ride over and be supported upon the loose rollers toothed ring supported therein, a crank-shaft havlng a gear mounted below the ring, and a series of loose rollers also mounted below the rlng, of a cylindrical grate-frame having a toothed lower edge loosely fitting within the ring and having its teeth engaging the gear of the crank-shaft and resting upon the rollers, an inclined flared flange located at the upper edge of the grate-frame and having tangentially-disposed ribs, a main central shaft journaled in the grate-frame, terminating at one end in a star-wheel, engaging the teeth of the ring of the ash-pit, opposite side shafts, disks mounted on the free shafts, and gear- Wheels mounted on the corresponding ends of the shafts and engaging each other, substantially as specified.
and by the same mechanism, substantially as specified.
' In testimony that I claim the foregoing as my own I have hereto affixed my signature in presence of two Witnesses.
\VILLIAM L. CARTER.
