JAMES \VELSH, OF PLYMOUTH, PENNSYLVANIA.
$PECIPIC'A'IION forming part of Letters Patent No. 309,590, dated December 23,1884. Application filed April 21, 1884. (No model.)
To a 7071,0721, it 'num concern.-
Be it known that I, Janus WnLsn, a citizen of the United States, residing at Plymouth, in the county of Luzerne and State of Pennsylvania, have invented certain new and useful Improvements in Grates; and I do declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
My invention relates to grates intended for use in large and small fires, furnaces, &c.; and it consists in the novel constructions, as will be described.
In the drawings, Figure 1 is a plan view; Fig. 2, a side view 3 Fig. 3, a detached section on line :0 a Fig. 1, of a grate constructed according to my invention.
The end shafts, A, are journaled at their ends in suitable supports, as B, and one of them is usually supplied with a crank, C, so the desired motion may be given the shaft, and thence to the grate, presently described. I by preference make these shafts angular, so as to serve as sprockets, though it is manifest the said shafts could be made of any desired form, and supplied with suitable sprocketwheels or pulleys to effect the operation of the grate. The grate proper is composed of a number of sections, D, pivoted together at their meeting ends, and arranged in a series of transverse rows, as most clearly shown in Fig. 1. A single red may be extended transversely across the grate, and serve as a connection and pivot for each of the sections'in line; or suitable independent pivots may be used for each adjacent section, as may be desired by the operator. It will be noticed the ends of the sections of one .row are inserted between the ends of the sections of the next row, so that there is a space left between each adjacent section for the passage of the ashes, which space or opening is preferably reduced in width by means of the lateral ribs (1, formed The inner sides or faces of these sections, it will be seen,
are rounded or made convex in longitudinal section, so that the ashes falling through the upper course of the grate onto the lower one will be guided by such rounded faces to the ends of the sections, and pass through to the ash-pit below, and the grate will not become clogged.
In operation, it will be understood, the supporting-shafts A A are arranged close to the side walls of the firechamber, whether of furnace or stove. grate is rotated on the shafts A, or may be given a reciprocating movement, at the will of the operator. This will evenly distribute the fire and shake same evenly and smoothly, as will be appreciated.
By my grate I am able to economically burn eulm and other coal-dust.
The grate can be easily operated, is simple of construction, and eflicient for the desired purpose.
It will be noticed that by pivoting the ends of the sections or grate-bars 1) directly to each other I form the operative grate without the intervention of endless chains, belts, or other supplemental carriers, which only render the devices complicated, more likely to become clogged, and of greater expense.
It will be evident that the grate-bars I) might be made without the lateral wings, (I; but in such case the bars wouldhave to be made very thin, or the openings would be too large to give good results, and as the bars when thin are liable to .become warped I prefer to employ the wings (I, as thereby the use of thick bars is rendered practicable and the openings are reduced to a suitable size.
Having thus described my invention, what I claim, and desire to secure by Letters Patent, rs-
1. A grate consisting of grate-bars arranged side by side in transverse rows, the opposite ends of the bars of one row being pivoted directly to the adjacent ends of the bars of the adjoining rows, the said grate-bars being formed midway their ends with late ally-pro jected wings whereby to reduce the area of the grate openings, substantially as set forth.
2. A grate consisting of a number of bars By means of the crank O the.
Lil
or sections pivoted at their ends directly to In testimony whereof I affix my signature in the adjoining ends of the adjacent bars, and presence of two witnesses. arranged in transverse rows, the said bars being provided with Wings projected laterally JAMES \VELSH. 5 from their opposite sides, and having their lower faces made approximately convex in Witnesses: longitudinal cross-section, substantially as set GEORGE S'rooKHAM, forth. GEO. MCALARNEY.
