GRATE.
Patented July 19, 1887.
NITED STATES PATENT OFFICE,
JESSE REYNOLDS, OF PHILADELPHIA, PENNSYLVANIA.
GRATE.
SPECIFICATION forming part of Letters Patent No. 366,687, dated July 19, 1887.
Application filed February 8, 1887. Serial No. 226,884. (No model.)
To aZZ whom it may concern.-
Be it known that 1, Jesse REYNOLDS,Of the city and county of Philadelphia, in the State of Pennsylvania, have invented certain new and useful Improvements in Dumping-Grates, of which improvements the following is a specification.
, My invention relates to dumping-grates of the type used in hot-air furnaces for heating dwellings and other large buildings; and the objectof my invention is to provide convenient and reliable means for lowering or raising the grate-frame containing the grate bars, whereby ashes, elinkers, and other obstructions from the fire-pot may be readily and effectively removed with the least possible trouble.
My invention consists of the construction and arrangement of theparts,hereinafter fully described, and pointed out in the claims.
In the accompanying drawings I have shown my invention in a form found practically efficien t, embodying the essential features thereof, and in which Figure 1 is aperspectiveview of a dumping furnace-grate constructed with rocking bars which serve as an effective medium for the ready withdrawal from the fuel of the superfluous ashes and cinder, and of the type shown and described in Letters Patent granted to me under date of June27,1876; but, however, my present improvements in mechanism for actuating such type of dumping-grates is equally applicable to and susceptible of use in round or square grates fitted with the old style of fixed bars. Fig. 2 is a top or plan of the grateirame, showing the rocking bars therein, and with my improved mechanism for raising and lowering the grate-frame shown in application; and Fig. 3 is a longitudinal section of a furnace ash-pit, showing the grate-bars and mechanism for rocking the same, and also showing one portion of my improved mechanism for lowering and raising the grateframe and holding the operatinglever in a lowered posit-ion while the grate-frame is in its normal operative position.
Referring to the drawings, A and A rep resent the side walls, and B the rear wall, of a furnace ash-pit.
C is the base-plate, and C the top plate, of the aslrpit, which is held firmly in place by means of a series of tie-rods, 0, provided with nuts a, passing upward through eyes 0" and 0', cast with the respective walls and plates forming the furnace ash-pit.
The top plate, 0, is provided with acentral annular opening, and around which open ng is provided a vertical flanged rim, (7, to wlnen is fitted the central combustionchamber of the furnace, of any well-known construction.
In a frame, E, constructed preferably in two parts joined together by means of bolts in any suitable manner, is provided a grate-frame, E, into which is fitted a series of rocking or v1- brating shafts, 0, having their bearings in the cylindrical surface of this grate-frame E, and on these shafts are fitted a series of curveshaped cutters 6, having ribbed sides, and ar: ranged so that the cutters or teeth on one shalt will interlock or come between those of the next shaft in regular succession.
From the middle of each shaft depends an arm, K, these arms K of the several bars being connected together by a rod, f, the outer end of which is hinged to a vertical arm,f, pivoted within abracket, F,cast with the frame E. This arm f has a horizontal projecting socket, f for the reception of abar,f, by the movement of which the several shafts carrying the cutters constituting the grate will be rocked to and fro simultaneously in contrary directions, withdrawing from the fuel in a more or less incandescentstate all superfluous ashes, and at the same time disintegrating all cinder that may be caught between the teeth or cutters by their toand-fro movement, as will be readily understood without further deseriptiom G and G are twolongitudinal arms, pivoted to the side walls, A and A, of the aslrpit by means of bolts 9, or in any othersuitable manner, and upon which arms, respectively, the frame F is supported, which carries the grate' frame E, to which a series of shafts, c, are journalcd, and carrying cutters 0r teeth 0, for grinding up clinkers and other non-combustible matter. The front portions of the arms G and G are preferably provided with vertical lugs 9, against which the frame E rests snugly to place, and prevented from sliding forward when lowered by the mechanism operating in the manner to be fully described.
To the longitudinal supporting-arms G and G are pivoted, by means of bolts and nuts h and h, toggle-levers H H and H H the tuggle-levers H and H being rigidly secured to a shaft, J, by means of a key,j, This shaft J is held in bearingsin the side walls, Aand A,
of the ash-pit, and to which shaft is attached aside wall of the ash-pit it may be located, if so desired; but I prefer to have it located in the face-plate of the ash-pit, because it occupies lessspace, and itis less expensive to build a furnace in the former manner. Hinged to the face-plate n by means of a nut and bolt, 0, is attached an automatic locking device consisting of a depending bar, to which iscast on one side a weighted arm, 1), and on the opposite side thereof a slanting projecting lug, p, which abuts snugly against the socket is when the frame E has been elevated to its normal position.
The manner ofoperating the dumping-grate, with the mechanism hereinbefore described applied thereto, being so simple, a further description of the invention isdeemed unnecessary; and therefore,
Having thus described the nature and objects of my invention, whatl claim as new, and desire to secure by Letters Patent, is'- l. The combination of an ash-pit, the supporting-arms G and G, pivoted to the side walls of the ash-pit, the frames E and E, the cutters e, the series of shafts e, jonrnaled to the frame E, the levers H and H", pivoted to said supporting-arms, and the levers H and H, pivoted to said levers and secured to the shaft J, the shaft J ,held in bearings in the side walls of the ash-pit, and the lever Z, carried by said shaft and operating to revolve the same and thereby raise and lower the frame E, substantially as and for the purposes set forth.
2. The combination of the furnace ash-pit, the longitudinal arms G and G, journaled to the side walls thereof, the frames Eand E, the curveshaped cutters e, and the shafts 6, held in bearings in said frame E, the lugs 9', cast with the supporting-arms G and G, for preventing the frame E from sliding forward thereon, the levers H, H, H and H pivoted to each other and to said supporting-arms, the levers H and H secured to the shaft J, the shaft J, held in bearings in the side walls of said ash-pit, the socket 75, secured to said shaft, and the vertical rod Z, fitting into said socket, for revolving said shaft and thereby raising and lowering said frame E, substantially as and for the purposes set forth.
3. The combination, with an ash-pit, the frames E and the cutters e, and shafts e, journaled to said frame E, two longitudinal arms, G and G, pivoted to the side walls of said ash pit and supporting the frame E, the toggle-levers H, H, H, and H pivoted to each other and to the arms G and G, said levers H and H being secured to ashaft, J, held in hearings inthe side walls of said ashpit, the shaft J, and lever Z, of the device 19,
pivoted to the front plate of the ashpit, with its weighted cross-arm p and lug p operating to hold the lever l in an elevated position while the frame E is in its normal position, substantially as and for the purposes set forth. In witness whereof I have hereunto set my hand in the presence oftwo subscribing witnesses.
