`GRATE FOR COAL-BURNING ASTOVES.

SPECIFICATION forming part of Letters Patent No. 329,206, dated October 27, 1885. Application filed December 31, 1884. Serial No. 151,624. 4(No model.)

To aZZ whom it may concern:

Be it known that I, DANIEL E. PARIs, a citizen of the United States, residing at Troy, Rensselaer county, New York, have invented new and useful Improvements in Grates for Coal-Burning Stoves, of which thefollowing is a specication.

It is the object of my invention to provide a grate for wood and coal burning stoves by Io which the ashes may be perfectly sifted, and in coal-stovesthe slag and clinkers thoroughly removed or the entire contents of the flrepot dumped, as circumstances may require.

The invention consists in a grate composed I 5 of three parallel sections, whereof the central part is capable of rotation and vibration,with a vibrating basket moving over or upon the outer sections and reciprocating at right angles to the axis of the central section, the side zo of the latter rising as the basket approaches it, whereby the cinders and slag are swept from the side grate-sections, and space given upon each side alternately for their discharge into the ash-pan beneath, the central section being also capable of being completely overturned to break up large adhering masses or cut the bottom out of cinder and slag accumulations which fill the re-pot.

My invention also consists in novel and sim- 3o ple means for operating the grate, and in the several features of construction and combinations of parts hereinafter fully described, and shown in the accompanying drawings, in which- Figure 1 is a plan view of the fire-pot of a stove containing my invention. Fig. 2 is a horizontal section takenin a plane just above the grate. Fig. 3 is a detail perspective of the basket detached. Fig. 4 is a vertical section 4o taken in a plane passingthrough one end of the stove just outside the gearing of the grate-sections. Fig. 5 is a detailperspective of apart of one of the outer gratesections removed from its support. Fig. 6 is a perspective showing one method of operating the grate. Fig. 7 is a similar view showing a modification of the construction shown in Fig. 7.

In the said drawings, the reference-numeral 1 denotes the body of the stove,which may be 5o of any desired form and construction. Within said stovebody, and occupying the upper portion of the same, is the fire-pot 2, beneath which lies the grate, composed of the three sectionsfS, 4, and i5. Of these the first and the last named are outer or stationary sections, and each is composed of a longitudinal bar, 6, having grate-bars 7 projecting from each side, those adjacent to the front and rear -walls of the stove being the shortest.

At one end of each bar 6 is formed a jour- 6o nal, 8, which engages with a seat, 8", in the stove-wall, a lug, 9, being formed upon the extremity of said bearing, which hooks into the aperture 8*. Upon the opposite side of the-bearing 8 is formed a depending lug, 10, 65 which lies against or between one or more bosses, 10, cast upon the inner face of the stove 1,whereby the sections 3 and 5 are prevented from rotating. Upon the other end of each bar 6 is formed-a plain cylindrical bear- 7o ing, 11, which is laid in a half-seat,11, cast upon the stove opposite each aperture 8,

Near each end ofthe bar 6, a flange, 12, is cast upon one of the grate-bars 7, rising slightly above said bar upon the side most remote from the end of the section. The purpose of this construction, which is the same in both the outer sections, will be explained hereinafter. The ange 12 crosses the longitudinal bar 6, and is extended upon a broad- 8o ened at bar, 12b, projecting from the outer edge of the bar 6, the end of the Iiange being curved or carried inward, as shown at 12.

The central section, 4,consists of a longitudin al bar, 13, having grate-bars 14 projecting from 8 5 each side, aeonnecting-web, 15, being formed between the adjacent bars intermediate of the base and the point. Upon one end the bar 13 has a cylindrical bearing, 16, which lies'in the seat 16 formed in the stove-wall, said bar be- 90 ing prolonged and its end, which projects through the wall of the stove, squared to receive a crank or key. The other end of the bar lies in a yhalf seat, 17, similar to those which support the corresponding ends of the. outer sections.

Adjacent to each bearing is formed a segment-gear, 18, projecting upward from the bar 13, for a purpose presently to be described.

Upon the outer sections, 3 and 5, is sup- Ioo ported a basket, 19,' consisting of an inwardlyinclined oval plate, 20, having 'a horizontal flange, 21, upon its longer sides, or, in other words, upon those sides which overlie the outer grate-sections. yUpon itslowcr .edge the rear portion of the plate 2O is provided with short teeth 22, those upon the front and end portions being preferably of greater length, as shown at 22. Near each end of the front and rear portions vof said basket one of these teeth is prolonged somewhat, and itspoint rests and moves upon the flanged bar near the end of each stationary grate-section, being guided in its movement by the flange 12. Upon each end portion of the basket is cast a rack, 23, which meshes with the segmentgears 18 upon the rotary grate-section. basket 19 lies intermediate of the grate and the fire-pot, although it in reality forms the lower portion of the latter. The repot, which is composed of sections 24of corrugated metallic lining or of re-brick,is,supported ,in

any suitable manner whereby the movement of the basket will not be obstructed.

When the parts thus describedare properly arranged with relationto each other, the several grate-sections will formlthe floor of the re-chamber,:the interval betweenthe bars of` the inner and those of theouter sections being only sucient to permit the rotation of `the former. `The teeth upon the basket willover- 'hang the outer sections and lie in close proximity to their surfaces, while thegears 18 and the racks with which they mesh will be `protected from clogging by the overhanging ends ofthe basket 19 and of the nre-pot.

The operation of these parts is as follows: By applying a key or crank tothe projecting squared end of the axial bar 13 in 'the central section a greater or less rotary movement may beimparted thereto, from a slightvibratory motion or shaking to a complete overturning or semi revolution thereof. Each movement of the central sectionis accompanied by a Acorresponding horizontal reciprocation of the basket 19, which is limitedin its movement by the curved extremities 12 of the flanges 12, and which is `caused to move toward the central rotary section as the adjacent edge ofthe latter rises and forms an opening between it and the outer section, through which the cinders and other refuse are pushed by the advancing teeth of the basket, which sweep over the surface of the outer sections. This reciprocation of the basket not only-serves to disintegrate accumulationswhich become packed in the lower part of the re-pot, but eo-operates with the other parts to form a per feet ash-sitter, thereby avoiding the necessity of removing the mingled coal, cinders, and ashes and sifting them by a separate apparatus.

If large elinkers are found in the hre-pot, they may be easily and quickly broken up by the rotary section of the grate, and when it is necessary to dump the contents of the flrepot the central section may be turned completely over, cutting the bottom out of the superincuinbent mass and bringing the `contents of the iire-pot down within the basket and upon the grate.

The

VIn operating the central or rotary section of A.the grate, an ordinary key or crank may be propose, however, to operate the grate and vibrate the basket by the following means: In

` Figs. 6 and 7 the numeral 26 denotes the body of the stove, which is shown as being cylindrical, but which may be of any form. The grate-sections are constructed and arranged in these stoves in substantially the manner heretofore described. Both ends of the longitudinal bar 13, which supports the central section, are prolonged to extend through the opposite walls ofthe stove, and upon these projecting ends are mounted downwardly curved arms 27, the lower ends of which support the footrail 28. Upon the outer face of this rail, and at theleentral portion thereof, is formed a handle,.29. This foot-rail serves as a lever whereby the grate may be operated and the basket vibratcd. In Fig. 7 .the construction and arrangement of parts is the same, with the exception that the foot-rail 28l is connected directly to the projecting extremities ofthe central bar .of the rotating section.

It is evident that the construction of the grate may be considerably varied without departing from my invention. The form of the basket and the manner of supporting it may also be modified, and I do not limit myself to the precise form Vor arrangement shown and described.

This grate operates upon the lower part of the {ire-pot, but far enough up to cut out the slag, `cinders, and other accumulation, at the same time making an opening for it to pass .down into `the ash-chamber. The same movementalso causes the grate to act after the manner `of a shovel to push the disintegrated matter vcut out by the upper portion down through the opening formed alternately upon each side, as shown in dotted lines in Fig. 4. The grate is also a perfect ash-sifter. NVith other grates the coals are packed together by vibration, thus preventing the free circulation of air, or else they cut oft the bottom ofthe fire. Both are objectionable, inasmuch as I want to use one motion when the iire is low and the other when the tire is strong but `clogged up at the bottom. In this grate I .get the benefit of both. The whole bottom of theire-pot can be vibratcd gently when the re is low,and thus remove the fine ashes, or, when needed, cut off the whole lower part.

Vhat I ,claim is- 1. The ,combination of a tire-pot, amovable grate, a basket above the grate, anda gearconnection between the grate and the basket, substantially as described.

2. The combination of an oscillating grate, a basket above the same, and a gear connection between the grate and the basket, substantially as described.

3. The combination of a grate composed of' the outer sections and a central oscillating see- IOO IIO

tion, with a basket above the grate, and a f section and the basket, substantially as described.

' '4. The combination of a fire pot, a grate beneath the same, and a movable basket having depending teeth bearing directly upon the upper side of the grate for loosely supporting the basket thereon, whereby the basket may be reciprocated in a right line across the grate, substantially as described.

5. The combination of a grate composed of two outer stationary sections and a central section provided with a shaft, a gear adjacent to each end of the shaft, and a basket having. racks engaging the gears, and provided with a toothed or notched lower edge, substantially as described.

6. The combination, with a re pot, of a Y grate composed of two outer sections, and a central oscillating section provided with gears, and a basket having a horizontal flange and provided with racks engaging said gears, substantially as described.

7. The combination of a movable grate, a basket above the grate, segmental gears connected with the movable grate, and racks upon the basket engaging the segmental gears, substantially as described.

In testimony whereof I affix my signature in presence of two witnesses.
