GRATE FOR FURNACES, 800.

SPECIFICATION forming part of Letters Patent No. 565,888, dated August 18, 1896.

Serial No. 558,646. (No model.)

To all whont it ntay concern.-

Be it known that I, FRANK P. FULLER, a citizen of the United States, residing at Mount Vernon, in the county of Knox and State of Ohio, have invented certain new and useful Improvements in Grates for Furnaces and the Like, of which the following is a full, clear, and exact specification.

My invention relates to a new and useful improvement in grates for furnaces and the like, and has for its object to provide such a device that will facilitate the removal of ashes and cinders from the fire without interfering with the dumping of said fire or the remains thereof.

With these ends in view the invention consists in the details of construction and combination of elements hereinafter set forth, and then specifically designated by the claims.

In order that those skilled in the art to which my invention appertains may understand how to make and use the same, I will describe its construction and operation in detail, referring by number to the accompanying drawings, forming a part of this specification, and in which- Figure 1 is a plan view of a grate embodying my improvements; Fig. 2, a bottom view thereof; Fig. 3, a section at the line a: as of Fig. 1; Fig. 4, a section at the line y y; Fig.

'5, a detail perspective of the rocking bar by which the several parts of the grate are supported.

Referring to the figures, 1 represents the base of a furnace, which incloses the ash-pit v2, and is adapted to receive and support a furnace of the desired construction, the lower edge of which fits within the annular flange 3 to form the fire-box. Cast or otherwise formed upon the inner side of the walls of the base are the lugs 4, having suitable bearings formed therein to receive the supporting-bar 5, which is adapted to rock at right angles to its axis for the purpose of dumping the entire grate at one operation. Formed with the bar 5 are two extensions 6, in which are curved slots 7, the purpose of which will he hereinafter set forth.

8 is a swiveled bar fulcrumed upon the bar 5 by the pin 9 and adapted to turn in a hole 10, formed in said bar. 11 is a shaker-bar, formed with the bar 8, and extending from the center thereof to the front of the ash-pit, and

terminating in a wrench-hold 12, by which the grate may be oscillated upon the pin 9 for the purpose of removing ashes, as will be hereinafter set forth. This shaker-bar is held in its normal elevated position by the rod 13, supported in the lugs 14, formed upon the sides of the ash-pit.

15 and 16 are two semicircular sections of which the grate proper is composed, and these sections are provided upon their under sides with depending lugs 17, having suitable bearings formed therein adapted to fit upon the bar 8, so that the sections may oscillate in the direction of the arrow in Fig. 3, independent of any other movement of the grate, for the purpose of dumping material upon the said grate into halves, as will be readily understood.

18 are two levers pivoted at 19 upon either side of the lug 20, which projects from the bar 11, and 21 are connecting-rods pivoted at 22 to the grate-sections and at 23 to these levers, so that any motion of said levers will be imparted to the grate-sections.

24 are operating-rods, pivoted at 25 to the levers 18, and extending through the front casing of the ash-pit and terminating in handles 26, and by these operating-bars the gratesections may be dumped independent of each other, or of any other movement of the grate, as before specified.

The rear end of the levers 18 are preferably weighted, so as to overbalance the grate-sections and hold them in their normal closed position.

27 and 28 are grate-bars, formed by a number of arms 29, projecting from a central bar, and these bars are pivoted at 30, within the grate-sections 15 and 16, respectively, and depending from these bars are the rods 31, which project into the slots 7, formed in the extensions 6 of the supporting-bar, so that upon the grate being oscillated back and forth, as indicated by the arrow in Fig. 1, the rods 31 will travel in the slots 7, which are of such contour as to impart to said rods a to-and-fro movement crosswise of the axis of the gratebars 15 and 16, which will cause said bars to rock upon their pivots 30, thus thoroughly agitating the coals upon the grate, and as this agitation takes place during the oscillation of the grate proper, it follows, that any refuse, such as ashes, will be quickly dislodged from the grate and caused to fall within the ash-pit.

From this description it will be seen thata grate made in conformity to my improvement may be dumped as a whole by the removal of the cross-rod 13, upon which the shakerbar 11 rests, or that one-half of the grate may be dumped by the proper manipulation of one of the rods 26, as before described, and also that the fire may be thoroughly agitated and relieved of its refuse by simply oscillating the shaker-bar. These combinations of movements are very advantageous in that they permit the proper regulation and manipulation of a fire within a furnace, with but little labor or skill upon the part of the attendant.

Having thus fully described my invention, what I claim as new and useful, is-

1. In a grate, the combination of a supporting-bar pivoted within the ash-pit and carryin g extensions having slots 7, formed therein, swinging bar 8, fulcrumed to the first-named bar, shakerbar 11, formed with said swinging bar, levers 18, pivoted to said shakerbar, grate-sections 15, and 16, pivoted. upon the bar 8, rods 21, connecting said grate-sections with the levers 18, operating-rods 24,

adapted to impart motion to said levers for tipping said grate-sections, grate- bars 27, and 28, pivoted within said grate-sections, rods 31, depending from said grate-bars, and projecting within the slots 7, substantially as and for the purposes set forth.

2. In combination, a supporting-bar pivoted within the ash-pit of a stove or furnace, diverging extremities 6, integral with the bar and havin g longitudinal slots, a bar 8, having a pin turning in the aperture of the supporting-bar, a shaker-bar 11, formed with the tensions 6, levers 18, pivoted to the lugs of the shaker-bar 11, and connecting-rods leading from the levers to the grate-sectionsand operating-rods connected with the levers, as

I and for the purpose described.

In testimony whereof I have hereunto affiXed my signature in the presence of two sub scribing Witn esses.
