. G RATE FOR HEATlNG-STOVES.

SPECIFICATION forming part of Letters Patent No. 370,362, dated September 20, 1887.

Application filed April 2, 1885.

To aZZ whom it may concern:

Be it known that we, WILLIAM E. WALKER and GEORGE E. WILBUR, both of Taunton, in the county of Bristol and State of Massachusetts, citizens of the United States, have invented new and useful Improvements in Grates for Heating-Stoves, of which the following is a-full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specilication,in describing its nature, in which Figure 1 is a vertical section from side to side of a stove containing the grate. Fig. 2 is a vertical central section of the said stove from front to back. Fig. 3 is a section upon and a plan view taken on a horizontal plane with the upper surface of the upper base-plate of the stove.

Theinvention relates especially to the means of supporting or hanging the grate for dumping it.

In the drawings, A is the ash-pit; B, the fire-pot; O, the combustion-chamber; D, the

outer casing of the main portion of the stove. E E are downflues connecting the combus tion-chamber with the base-flue. F is the uptake. G is the grate. It is carried or supported by the crossbar g, which extends from side to side across the upper portion of the ash-pit chamber, and has bearings g in the plates forming the sides of the ashpit chamber, and one end, 9 extends through the outer plate of the base-section, and is shaped to receive a wrench or handle, whereby it is turned. The cross-bar 9 also has a backward-extending arm, 9 (see Fig. 2,) the end of which enters a slot, 9, in the downward-projecting lug 9 extending from the under surface of the rear portion of the grate.

The back edge or section, 9 of the grate is supported, when the grate is in a horizontal position, by the shoulder or ledge g which projects downwardly and outwardly from the plate h, which supports the firebrick. The front portion or section, 9 of the grate preferably extends beyond the inner line of the fire-pot wall, as represented in Fig. 2. The front portion, of the combustion-chamber does not extend down to the Serial No. 161,018. (No model.)

vide a space by which the upper surface of the grate can be reached from the door 9, and also to prevent the contents of the combustion-chamber from crowding into said space.

It will be observed from the above description that the grate is arranged to dump its contents toward the front of the ash-pit chamber, and that the arm 9 of the bar G strengthens the support and balances the grate, so that it is firmly held in a horizontal position against the shoulder and cannot readily be tipped from that position, unless the door 9 is turned; also, that the arm 9 acts as a lever when moved by the arm 9", and brings the turning bar or force against the back edge of the grate, so that the dumping or turning of the grate is more easily accomplished.

It will be observed that by means of the opening 9 and by hanging the grate so that it can be moved or tipped slightly downward at the front, clinkers can be readily sliced or moved off its upper surface into the ash-pit chamber below.

The subject-matter of this application was originally described in our application for Letters Patent filed December 22, 1884, Serial No. 150,907, and was removed therefrom by amendment duly filed.

Having thus fully described our invention, we claim and desire to secure byv Letters Patent of the United States- 1. The combination of the grate G, the slotted lug extending downward from its rear end, the operating-bar g and its backward-extending arm 9 the end of which enters the slot in the said lug 9 all substantially as and for the purposes described.

2. The combination, in a stove, of the fireenters the slot in the said hanger 9 as and for pot having the fingers h extending downthe purposes described. ward and inward from its front wall into the chamber or space 9", the said space or chamggg Q 5 ber 9 the door 9 thereto, the grate G, having the hanger or lug 9 extending downward Witnesses:

from its rear end, the operating-bar g and its JOHN F. MONTGO ERY,

backward-extending arm the end of which ELISHA T. J AOKSON.
