Be Vit known that I, J, J. SAVAGE, of 'Iroy,.in the county of Rensselaer, and State of New York, have invented a new and improved Grate for Stoves; and I do hereby declare that the following is a full, clear, and

.exact description of the construction and operation of the same, reference lbeing had to the annexed drawings Vand to the letters offreference marked thereon, forming part of this specification, in which- Figure 1 is a perspective view of said improved grate as arranged and combined for use in a self-feeding stove.

Figure 2 is a vertical sectional view of said stove and grate, the end plate being in part removed to more clearly show the manner of operating said grate to dump clinlrers and cinders therefrom, and also to show the manner of holding back the fuel in a reservoir of self-feeding stoves while dumping the grate of the same.

Figure shows a modification of construction and arrangement of said improved grate, as shown in fig. 2.

Figure 4 shows another modification of the same.

Figure 5 shows an additional device to the arrangement and combination, as shown in iig. 3.

Figure 6 shows a manner of` using my said improvements incombination with a non-dumping :fire-grate.

The same letters refer to'like parts in each of the said figures.

The 11a-ture of my said invention and improvements consists in constructing for stoves a fire-grate composed of acurved or angular-shaped lifting and hold-back grate part, provided with end or side pieces, and suspended within the fire-box by journals, that it may swing upward when operated, and having arranged to operate in combination therewith a horizontal or front fire-grate part, which jointly with said lifting and hold-back part constitutes a fire-grate, the same substantially as hereinafter fully described.

-It also consists in the arrangement, in combination with a fuel-reservoir of stoves and `a horizontal or front grate part thereof, of a lifting and hold-backgrate part, arranged in such position thereto,..1espectively,

as to operate to lift from the ie-boxand retain within said hold-back grate part awportion of live coals, and

likewise prevent fuel falling out of said fuel-reservoir while said horizontal or froiit grate part is cleaned of clinkers and other refu'sematters, substantially as hereinafter fully set forth. v

It also consists, in combination with a fuel-reservoir of stoves and fire-box thereof, of a lifting and hold-baclc grate part, arranged in connection with a dumping or tilting-grate part in such a-manner `Jthat said hold-back grate part is operated simultaneously by and with the `dumping or tilting-grate part, in manner substantially and for the purpose as hereinafter fully set forth. o

It also consists in combining, with a fire-grate `and a lifting and hold-back grate or plate, a lifter-arm arranged to work loose on the journal of the fire-grate, in manner substantially and for the purpose as hereinafter set forth.

To enable others skilled in the art of constructing stoves andpnre-grates to construct and use my improved fire-grate, I will now proceed to fully describe the same, to wit:

In the annexed drawings, A shows a heating-stove, one of those provided with a fuel\eservoi1',l, for holding a supply of fuel for self-feeding the fire in the usual known manner. C is a fire-grate, which occupies about oneshalf, more or less, of the horizontal area of the lire-box. is a lifting and hold-back grate or plate, provided at its upper part with bearings or journals FF, or their equivalents, upon which it operates or turns when lifted up from or droppeddown to the ire-grate used with it. The bottom or lower parts of this liftingfgrate or plate can be formed into gratehars, which may extend more or less up the back part of said liftingfplate or grate D, and at each end of the same may be side pieces G. vOne of the journals F projects through the side plate of the stove, so' that it can receive a lever with which ,said lifting-plate D may be turned up and turned down, or it may be turned up by a loose lifter-arm hereinafter described, or any other suitable contrivancc may be used to turn up and down said lifting-plate D whenever it is necessary to clean the fire-gate C from clinkers or slate. This lifting and hold-back grate or plate D is arranged'in position between the feed-month of afuelreservoir of self-feeding stoves and the fire-grate used in connection with said reservoir, substantially in manner as shown in figs. 1 and 2 of annexed drawings.

The aforesaid' fire-grate C may beveither a non-dumping one or a' dumping or tilting one, 'as the proposed manner of operating the aforesaid lifting and hold-back grate or plate may require, that is to say, when the aforesaid liftingr and hold-back grate or plate D is operated by itself, to lift from the fire-box 'and hold-back a portion of live coals, and also to hold back the fuel in the reservoir, a non-dumping fire-grate 'can be used;but

when the aforesaid lifting and hold-back grate is to be operated by and in connection with a'fire-grate, C, a dumping or tilting nre-grate is then tobe used. i y

The operation of this lifting and hold-baclt grate or plate D, as placed in* interposition between a fuelreservoir and a non-dumping fire-grate of self-feeding stoves, is :is follows: A lever is lapplied to the said pro-v jecting journal E, and the aforesaid lifting and hold-baek grate-or plate D is turned upv by it, in manner as .shown in fig. 6, thereby lifting and holding back from the fire-box a portion of live coals, and also at the saine time holding back the fuel in the fuel-reservoir B, said lifting and hold-back grate being held up byeatching the lifting-lever on a stud er hook, orlanypther suitable eontrivance may be used to turnand hold said liftinggrate or plate up while elinkers and cinders are beingremoved from the fire-grate by means of a poker orf'other convenient article for such purpose. 'After removing the clinlcers and einders, the lifting and hold-back grate or plate is then dropped down to the tire-grate C again, and the live coals before lifted and held back from the re-box now serve to again start the tire in the fire-boit. Thus no material interruption of the fireis occasioned by the operation ofcleaning the fire-grate C,as in manner above described.

When the aforesaid lifting and hold-back grate or plate D is to be operated by and in connection with a fire-grate, G, the hre-grate is then constructed to dump or tilt its contents into the ash-box. or pit; and it is also constructed with lifting-arms E, extending back from the grate in manner substantially as shown in fig. 1, there being a lifting-arm at each end of said vdumping-grate, or one aru'i arranged at and projecting from the central parts of the baclc'of said fire-grate may be used, substantially in manner as shownjn fig. 4. One of the journals H of said dumping-grate passes through theouter plate of the stove, and it is fitted to receive a lever and be turned byl it, thereby dumping or tilting said grate C. The aforesaid lifting and hold-back grate or plate D is arranged in relation to the feeding-mouth of a fuel-reservoir of self-feeding stovesand combined with it so as to act in manner as hereinafterdescribed.

A dumping or tilting hre-grate, C, and the aforesaid lifting and hold-back grate or plate D being arranged in astove, in combination with each other andV with a fuel-reservoir in manner substantially as herein shown, jointly form a good and efficient fire-grate surface for the fire-box of the same, and its operation when thus arranged and combined is as follows, to wit: A suitable lever` is applied to the projectingjournal-head H and turn ed quickly downwards, thereby dumping the iiregrate.0, in manner as shown in'iig. 2, so that the elinkers and cinders lying thereon are cast down into the ash-box or draw l, and at the same time the dumping motion of the fire-grate carries up the lifter-arms E, which in their up motion act upon the side pieces G of the aforesaid lifting and hold-back grate D, which causes the lower part of said grate D to turn up and lift from the re-box and carry with it a portion of live coals to the mouth of the fuel-reservoir, where said grate or plate D acts to hold' back and prevent the fuel in said reservoir from falling out ofthe saine into the fire-box and ash-pit when clinliers and cindcrs are dumped from said grate C, in manner as shown in said fig. 2.

After said dumping fire-grate is cleaned from clinkers and cinders, the dumping-lever is quickly reversed vin its m0ti on,'thereby causing the lifting and dumping-grates to return to their proper position as they were before, as shown in iig. l., for supporting the fuel in the drehen. The live coals lifted from the fire-box by the operation lof said lifting-grate or plate D, falling down first on the fire-grate C, serve to kiudle the fresh fuel fed from the reservoir upon said live coals, and thereby preventing any inconvenient or material interruption of the fireby-the operation of dumping clinkcrs and cinders from the same.

Fig. 3 showsa modification of the construction, as shown in iig. 2. In this modification the lifter-arms E are aiixcd tothe lifting and hold-back grate D insteadof being attached to the tilting fire-grate C as before,

`and said grate fs tilted er turned up, or innn opposite direction from that shown in fig. 2, by which operation the said grate, acting enthe lifter-arms E attached to the lifting-grate D, lifts said grate up in manner as shown in fig. 3, thereby lifting up a portion of live coa-ls from the {ire-box and holding back the yfuel in the .fuelreservoir, and also tilting the Ere-grate C, so as to dump cinders and clinkers'from the same, substantially inmanner as is done by the arrangement as shown in fig. 2. i

Fig. 4 Shows a manner of arranging a-lifter-arm, E, when the aforesaid improved grate is to be adapted to an oval or a circularform of fire-box.

Fig. 5 shows a combination of an additional device, vwith'the arrangement and combination. of dumping or tilting fire-grate and lifting and hold-back grate or plate, as described and shown in tig. 3, which vis for they purpose of turning up the aforesaid lifting-grate or plate D a distance more or less, as previously arranged for before the tilting movement of said fire-grate C commences, thereby obtaining a more free discharge of clinkers and einders from said lire-grate, when its succeeding vtilting movement docs commence thanv wouldhave been a e a e I u l l o n had without using said additional device. Said device consists of a lifter-arm, L, arranged en the l)ournal H ot the dumping-grate C, and so aste work loose on said journal, while it rst turns up the aforesaid lifting-grate or plat-e D without moving the tilting or dumping fire-grate C the distancearranged for it to so move. It then, together with completing the upward movement of vsaid lifting-grate D, acts upon a pin or stud; afiixed to tbe dumping or tilting fire-grate b'y means of a connecting. hook. or link, a, or by other suitable means for that purpose, and thereby dumps or tilts the same, soa-s to cast the elinkers and cinders freely therefrom,

The advantages secured by my improved stovegrate are as follows, viz i Whea'used in combination with a fuel-reservoir; of self-feeding stoves it enables such a stove to dump readily and effectively all refuse matters frein its front or horizontal `{irc-grate part witlioutfuel falling froin the reservoir into the ash-pit while so dumping' and cleaning the grate. This improved fire-grate ina-y likewise be used in stoves not having fuelreservoirs, thereby enabling such stoves that-use itvto dump clnkers andother refuse substances from their fire-boxes without dumping the whole lire into the ash-pit to free tlie'grate of clinlters :is is done withtheordinary dumping irc-gralte, but a portion of live coals is lifted from the firebox by said lifting and hold-back grate part and reta-ined within it until the lioiizontaliire-grate is dumped or cleaned of clinlici's and cindei's; then,

when said lire-,grote is re-adjusted for use, the reserved portion of live coals serves to start thetire again by quickly igniting a fresh supply of -fuel placed thereon.

What I claim as my invention, and desire to secure by Letters Patent, is-

1, Isla-im are-grate for stoves composed of a. curved or angular-formed lifting and hold-back grate part D, having side or end pieces G G, and suspended within the tire-boxv by journals F F,or their equivalonts,in such manner1` that it may swing upward, for the purpose herein set forth, and having arranged to operate in combination therewith a. horizontal grate part, C, which, jointly with said grate part D, constitutes said firegrete, in manner substantially as herein described and operating for the purposeset forth.
