REFUSE-CREMATORY.

SPECIFICATION forming' part of Letters Patent No. 674,319, dated May 14, '1901. Application filed December 15, 1900. serial No. 39,989. (No model.)

.To all whom, it Wto/,y concern:

Be itknown that I, WARD RISLEY, a citizen of the United States, residing at Jacksboro, in the county of Jack and/State of Texas, have invented certain new and useful Improvements in Refuse-Crematories; and I do hereby 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 g it appertains to make and use the same.

My invention relates to Crematories or fur; naces for burning garbage and other matter; and it consists of the novel structure and combination of parts hereinafter more particularly described and claimed.

Referring to the accompanying drawings,

which illustrate a form of my invention, Fig^ ure l represents a vertical central sectional View of the crematory with parts shown in elevation broken away. Fig. 2 is a transverse vertical sectional View of the saine. Fig. 3 represents a section taken along the line 3 3, Fig. l. Fig. 4 represents a section taken along the line 4 4, Fig. '1. Fig. 5 represents a section In the lower part of the furnace or garbagechamber are the flre-grates C, C', and C2, into which lead the fuel-openings'c, c,'and-c2.'

These fire-grates are closed in by the transverse tiles c3 c4 and c5, the tile c4 extendin r higher than the others.

At about the center of the chamber A is a garbage-grating comprising a series of tubular'cross-bars D, mounted upon rods CZ. These bars extend across the chamber, as shown most clearly in Fig. 2, and the grating which they form extends almost the entire length of the chamber and near the forward end takes an upward curve, as at d', to prevent garbage from falling off the grate into the passage leading to the chimney. The bars of this grate are close together, but do not touch each other. The grating over the fire-grate C is separated from the rest by the tile c4.

In the bottom of the chamber AA and extending almost the entire length thereof is an eVaporating-pan E, preferably semicircular, or approximately so, in cross section and closed at its ends. A flange e extends around the upper edge of this pan and supports it by resting upon the flanges b', formed upon the lowerV edge of the iron casing B, and a flanged support b2, which also supports the tile c3. The end of the evaporatingpan beneath the fire-grate C is covered by means of a removable plate e, which rests on the end of the pan and upon a flanged support b3, the latter supporting also the tile c4.

In the brick housing F are the stokingdoors G G, which communicate by passages g g with the inside of the chamber. A door G' and passage g open into the lower part of the chamber for the admission of a device for stirring or agitating the contents of the evaporating-pan.

A brick housing F incloses `the roasting- 'chamber A and is located at a sufficient distance from the outer iron casing of the said roasting-chamber to form a chamber in which air may be heated by radiation from the roasting-chamber and utilized; for any desired purpose, such, for example, as heating feed-water for steam-boilers, heating buildings, &c. It will thus be seen that bythis arrangement the same fire that is used for destroying the garbage and other refuse may be used for heating purposes. This heated air surround- 'ing the chamber A may be conducted off to any desired point by the flue or duct F. The hot-air space surrounding the furnace proper furthermore acts as a jacket and prevents loss of heat by radiation and at the same time acting to heat the lower ends of the chargingtubes, which will cause to be -burned or removed material that would have a tendency to stick to that part of said tubes were they v 4not kept hot. Moreover, byv thus creating a heated zone through which the garbage passes just prior to reaching the furnace the garbage may be more quickly and readily burned. The foul gases and gases of combustion do not pass into the chamber which surrounds the roasting-chamber A, but pass directly from the bottom of that chamber through the duct t' into the chimney I, located to one sideof the housing, as shown, so that the interior of the IOO roasting-chamber is entirely cut off from the chamber which surrounds it. The admission of cold air into the hot-air space or chamber between the brick housing and the roasting chamber is regulated by the damper J. Access to the bottom of the furnace is afforded l by the door K.

The garbage or other refuse is charged into the crematory through a number of chargingi tubes. In the drawings I have shown three of these, L, L, and L2, which pass from adesired point above the `housing F through it into the chamber A. I have represented ai platform M above the furnace, upon which platform the garbage to be burned may be dumped, or this platform may represent any floor in the building with which the furnace or crematory is used. The upper end of the 3 charging-tube L is flanged, as at Z, whereit engages the platform and is provided witha removable cover l'. Into this tube is charged the dry refuse, while the more moist or liquid portions are charged into the tubes L and L2. The tubes L and L2 are provided with removable extensions Zgand Z3, respectively. In the lower ends of these extensions are pivotedthe bowls N N', which are adapted to rotate on the spindles n n', respectively. i These spindles are connected by arms n2 and ois, respectively, to the levers n4 and h5, which are in turn .pivotally connnected at their upper ends to the hinged covers @t6 917, which close the tops of the tubes L L2.

O O' represent two llushing-tanks located above the tubes L and L2, respectively, one of said tanks being oneach side of a partition P. The pipes Q Q' connect the tanks O O' with the upper extensions of the tubes L andL2,1'espectively,the said pipes discharging the Water from said tanks `into the tubes or bowls. Each of these tanks is provided with 1 a float R, which is connected by means of a; spring r and bolt r' with one end of a lever S, i'ulcrumed to the top of the tank. To the bottom of the ioat is secured one end of a; pivoted arm T, which carries upon its other end a valve t, which is `adapted to close an. opening '150, into which lpasses the water-suppl-y pipe t. The flow of the water from the tank into the pipes Q Q' is controlled by` valves U, each secured to one side of a .pivoted arm u, mounted in the flushing-tanks. rlheotherend of each of the said arms u being connected by links it to the lever-arms S. The ends of the-levers S opposite the end connected to the floats are connected by rods V V' to the short arms y'u fu', respectively, which latter are in turn made fast tothe covers n n?, respectively.

While fnrnacesfmay be constructed as above described upon a large scale for burning the ordinary garbage collected from cities or towns, the crematory herein described is especially well adapted for use in burning the refuse from water-closets of jails and other public buildings or private dwellings which have no sewer connections. In such cases the refuse from the water-closet bowl would instead of being discharged into a sewer be discharged int-o one or both of the tubes L L2. When used to burn the refuse from water-closets, the hinged Itops upon the tubes would be employed as covers upon the seats of the closets, and the flushing device described would be that used with the closets, or any other suitable dushing devices may be used. Obviously when the crematory is used in such cases as this the closets would be located far enough away from the furnace to avoid the heat, and the ordinary garbage and refuse from the house would be deposited in the tube or opening L.

The operation of the device is as follows: Assuming that fires are burning in the grates C, C, and C2, the garbage is dumped upon the grate D through the charging-tubes L, L', and L2. In charging the dry refuse or garbage through the tube L all that is done is to remove the cover l and dump the garbage or refuse into the tube, when it falls upon the grate and is consumed, as will be hereinafter more fully described, and when a sufficient quantity has been charged iniothe said "tube the cover is replaced. In charging the more liquid garbage through the tubes L L2 it will have a tendency to adhere to the tube and accumulate there. 'lo prevent this, I eu1 `ploy a flushing device such as 'herein shown anddescribed, which insures agreat degree of cleanliness, that could not otherwise generally be attained. Vhen it is desired to charge `the furnace through either of the tubes `L or L2, these covers are raised, as shown in Fig. l, where the cover it is supposed to open. W'hen this isdone, the bowl N assumes the `position shown, 'its edge eugaging a lug its, which `prevents it from turning too far. When the cover is thus raised, the lever-arm S will cause the float R to rise, Which, acting through the arm T, Ywill close the valve t to the supplyfpipe and open the valve U, which will allow the water from the tank to `pass out of the outlet-pipe Q and thence in to the ,tube L and bowl N. The garbage is then dumped into the tube, and when a sufficient quantity has been thus deposited the iop of the tube is closed, which causes the bowl to dum p to the position shown atN,whcn its contents will fall upon the grate. The closing of the cover of the tube also causes the valve U to close the outlet-pipe from the flushing-tan k and the valve t to open the supply-pipe entrance into the tank, allowing. the water to flow into'the tank until the float rises to a sufiicient level to bring the valve t upon its seat and close the end of the supply-pipe. The garbage falling upon the grating D will be consumed by the lires from`below,while the noxious gases arising from the garbage will mingle with the products of combustion from the fires and be burned therewith before leaving the furnace. The products of combustion from the fire in the grate C will pass over the tiling c5 and around through the pas- TOO IIO

IZO

sage A' into the chimney I; but the gases and other products of combustion from the grates C and C2 will pass both beneath the grating D and then over it, when they will mingle with those from the grate C and pass together therewith into the chimney. The drippings from the more moist garbage will fall into the pan E, where they will be quickly evaporated, the vapors therefrom commingling with the gases from the lires and being consumed as they pass therewith through the furnace, as described. The heated gases passing beneath the evaporating-pan will keep it at a high temperature, and thus insure rapid evaporation.

Having thus described my invention, it is obvious that the same is capable of many modifications which might be made without departing from the spirit of the invention.
