V IMPROVEMENT IN GRATES.

Specification forming part of Letters Patent No. 40.34 I, dated October 20, 1863.

To all whom, it may concern:

Be it known that 1, SAMUEL J. KELLY, of Pemberton, in the county of Burlington and State of New Jersey, have invented a certain new and useful Improvement in Stoves and other Grates; and I do hereby declare the following to be a full and exact description thereof, reference being had to the accompanying drawings, making part of this specification, in which- Figure 1 is a front end elevation of my improved grate. Fig. 2 is a plan thereof, showing the movable portion of the grate partially withdrawn. Fig. 3 is a vertical section of a portion of the same, taken in the line was, Fig. 2.

bimilar letters of reference indicate corresponding parts in the several figures.

This invention consists in a grate of peculiar and simple construction, designed to facilitate the removal of cinders, ashes, and other refuse.

To enable others skilled in the art to which my invention appertains to fully understand and use the same, I will proceed to describe its construction and operation.

In the accompanying illustration of my im proved grate A A A represent separate castiron or other metallic plates, formed with flanges a a a at top, which are designed to rest upon a horizontal rib permanently located within the stove at the front thereof, and thus to constitute the ineans for sustaining this part of the grate. To these plates are attached at suitable regular intervals the gratebars B, the lower front portions of which are curved in the usual manner. At their opposite horizontal ends the bars, which are attached to the plates A A, are secured in corresponding notches formed in a horizontal bar, (J, extending from end to end at the back of the grate. The form of this bar is clearly shown in Fig. 2. Those portions of it occupied by the bars of the plates A A, are of uniform dimension. At the termination of these portions, where it is intended to insert the bar D, to which the grate-bars of the plate A are attached, the bar 0 is formed with conver ing or oblique rests or projections E E, upon which the bar D is to be supported, the ends of the latter being formed to correspond therewith, as shown by dotted lines in Fig. 2.

I'Vheu it is desired to remove the contents of the grate for the purpose of rebuilding the fire, this may be expeditiously performed by merely placing the hand beneath the central section, A a. pressing it slightly upward and then drawing it forward a little. Thus a sufficient space is made to permit the passage of cinders, ashes, or other refuse, most of which are precipitated into the ash-pan below by the movement of the section A a.

I am aware that it is not new to construct grates with one or more removable bars for the purpose of facilitating the clearing of the grate. One among many examples of this is seen in the patent of Wm. L. McDowell, granted April 28, 1863.

My invention is a new and improved construction of the parts to effect the above object. Its superiority over that of McDowell, above referred to, consists in providing for the removal of a section of the front and bottom of the grate, the aperture thus formed extending completely around from the top to the extreme rear and lower part without the intervention of any transverse bars to interfere with the freedom of the discharge.

Having thus described my, invention, the following is what I claim as new therein and desire to secure by Letters Patent:

In combination with the plates A A a a, grate-bars B, and bar 0, the movable section A B, supported at front by means of the flange a, and at back by the beveled bar D, resting in a corresponding recess, E E, in the bar (3, when the said movable section extends completely around from the front and top to the lower and rear part of the grate, and all the parts are constructed and arranged in the manner and for the purposes specified.

SAMUEL J. KELLY.
