GRATE FOR HEATING SYSTEMS, 86C.

SPECIFICATION forming part of Letters Patent N0. 625,6 59, dated May 23, 1899. Application filed May 9, 1898. Serial No. 680,151. (No model.)

To @ZZ whom, t may concern:

Be it known that I, HARVEY K. ERNsBER- GER, a citizen of the United States, residing at Norwalk, in the county of Huron and State of Ohio, have invented certain new and` useful Improvements in Grates for Use in Heating Systems, dac.; 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 t the figures of reference marked thereon, which form a part of this specication.

My invention relates to an improvement in grates adapted for use in furnaces or other like heating appliances, and is particularly designed for use in combination with the heating system set forth in Letters Patent numbered 578,482 and granted to me on the 9th day of March, A. D. 1897, in the place of the grate therein described.

The object of my invention is to provide an easily-manipulated, durable, and economical device of the class mentioned adapted to shake or agitate the fire-bed either wholly or in part, as desired, whereby the ashes may be made to drop into the subjacentash-pit, while the waste of live coal is reduced to the minimum, all of which I will more fully describe hereinafter. I

In the accompanying drawings, Figure l is a general view in perspective, partlybroken away, of my improved grate as it appears when in position within and supported by a partially-completed brick casing. Fig. 2 is a side view of the same apart from the casing.

Similar numerals of reference when they appear indicate corresponding-parts in both figures of the drawings.

1 designates the partially-completed brick v casing, the residue of which may be constructed in the usual manner.

2 represents a series of horizontal watercirculating pipes arranged in alinement parallel and a distance apart, one end of each of which communicates with the base portion 3 of a hollow device or manifold, the residue of which manifold may be of any suitable form,

but preferably of inverted-V shape, the completed whole forming a triangle. The balance of the device, or what might be termed i the grate proper, consists of a number of I grate-bars 4, which, like the pipes 2 between which they lie, are, it is plain, also arranged inhorizontal alinement parallel and a distance apart. The lower notched edges 5 thereof rest on and said bars are supported by crossbars 6, the upper edges 7 of which are-also notched. The notched edges 5 and 7, it is evident, are adapted to take one into the other or interlock. Parallel with said cross-bars 6 are a pair of shafts or drums 8, each being provided at or near one of itsends with a vertical lever or handle 9 and ata distance from each endv with a downwardly-inclined arm 10, each of which passes into and a distance through a slot l1, found in each end of the cross-bars 6 and adapted as the levers or either of them are worked to elevate one end or the series of grate-bars, as the case may be, there- 'by agitating the lire supported thereby and by the pipes 2 to remove the ashes which drop into the subjacent ash-pit and with but little loss of live coal. l

Itis obvious that the pipes' 2 being when in use full of water are nearly fire or heat proof and tend to preserve the adjacent gratebars, and the heat `which in other devices of this nature destroys said bars' is by virtue of the peculiar construction of this device beneiicially utilized.

Having thus described my invention, what I claim, and desire to secure by Letters Patent, is-

In a grate, a suitable inclosing wall, a manifold arranged in the front end of saidinclosing wall onV a level with the grate-bars, and a series of stationary pipes which are connected tothe manifold, combined with a series of rocking or tilting grate-bars 4 which are placed between the pipes, a shaft extending horizontally across at each end of the gratebars, arms 10 projecting from the shafts, and supporting the cross-pieces 6 upon which the grate-bars rest; the outer ends of the shafts projecting through the inclosing wall and provided with levers orhandles' whereby either or both of the ends of the grate-bars may be rocked, substantially as shown and described.` In testimony whereof I affix my signature in presence of two witnesses.
