i machines, and has for an object to provide a machine adapted for digesting, draining, and drying refuse of any nature in a single receptacle and in practically a single operation.

A further object of the invention is to provide a refuse-reduction machine wherein the refuse is taken in its ordinary or natural condition and reduced to a dry and inodorous condition while continuously hermetically sealed, being dried'at a temperature so low as to revent ignition:

further object of the invention is to pro vide a refuse-reduction machine capable of angle-irons 21, extending longitudinally of reducing. to a dry condition refuse therein contained in the shortest possible time and with a minimum expense and labor.

" mounted to rotate upon idlers and provided Specifically the object of the invention is to provide a jacketed cylindrical receptacle with means for the introduction of-live steam during the rotation for digesting the contents, after which the surplus liquid 'is filtered off and the contained air exhausted. Live steam is then admitted between the cylinder and its jacket to heat the cylinder for drying the contents under vacuum, the vapor passin away through the vacuum-pipe.

1th these and other objects in view the invention comprises certain novel construction, combinations, and arrangements of parts, as will be hereinafter fully described and claimed.

In the drawings, Figure 1 is a Vertical longitudinal sectional view of the improved reduotion-machine. Fig. 2 is a transverse sectional view of the machine, taken on line 2 2 1 of Fig. '1. Fig. 3 is a plan View of the perfo rate filter-bottom of the machine with the several constituent elements of said bottom so broken away as to show each. Fig. 4 is an .enlarged detail view of a fragment of. the rece tacle and jacket as shown at the lower si eof Fig. 2 and a transverse section of the parts shown in Fig. 3.

Like characters of reference designate corresponding parts throughout the several views. y

In its preferred embodiment the improved reduction-machine forming the subject-matter of this application comprises a cylindrical receptacle 10, concentrically secured within theijacket 11, spaced therefrom at oneend and completely around the said receptacle, except beneath the perforate bottom 12 formed in the receptacle. disposed within an opening in the periphery of the receptacle extending approximately throughout its length and occupying a small circumferential arc. The said perforate bottom is composed of a plate 13, having openings or thimbles 14, upon which is disposed a late 15, having small perforations. with a filter fabric 16 secured upon the said plate 15 by means of the screen fabric 17. The sev eral plates and fabrics are secured in position The bottom 12 is by means of clips 18, clamped upon the frame 19 by means of bolts 20 inserted through holes 21.

Within the receptacle 10 are secured the the receptacle and with one member of said angle-iron extending radially and inwardly from the shell of the receptacle. 1 About the the perforate bottom and the jacket is separated from the space between the jacket and thereceptacle, and communicating with the chamber thus formed is a pipe 23, provided with a cook 24 for withdrawing surplus liquid from the said chamber which asses through the perforate bottom into said member.

For charging the receptacle manholes are provided formed by the upstanding bosses 25 about one or more openings in the top of the said receptacle and closed by the cover 26, secured in any approved manner, as by thelever -nuts 27 upon the pivoted eyebolts 28, About the opening communicating with the'said manhole a frame or liner 29 is dis osed, whereby the space between the jacliet and the receptacleis closed from communication with the said manhole.

About the casing is secured the bands 30, carried upon idlers 31, 'ournaled in. pillow blocks 32, secured upon sills 33 or in any other approved'manner. Opposite one of the bands 30 is secured a rack-ring 34', en aging the pinion 35, mounted upon the sha 36, upon with theusual and ordinary cover and coverwhich a secured one of the idlers131, which is rotated by means of the friction-clutch (shown conventionally at 37) and driven in ling 43 and with a steam-pipe 44, connected therewith at right angles and with a valve 45, arranged to control the flow of steam throu h said pipe 44. The. pipe 39 is'continued by the pipe 46, into which .the valve 47 is introduced and which communicates with any approved source of pneumatic ex haustion. (Not shown.) At the end opposite the jacket is provided witha gland 48, through which extends a pipe 49 into the space at the end between the jacket and the receptacle. Without the jacket the pipe 39 is provided with an elbow 40, having a packing-box 50, arranged in axial alinement with the pipe 39 and through which extends a pipe 51, connected at its outer end with a steam-trap (shown conventionally at 52) and with its inner end depending within and adjacent to the-periphery of the jacket, as at 53. Connected with the elbow is also a steam-pipe 54, into whichis introduced the valve 55 for controlling the flow of steam therethrough, and a manhole or hand-hole 56 securing means 1s provided in .the end ofthe jacket 0 tween the jacket and receptacle.

For convenience the terms bottom and top have been employed in the descrip-- '.tion of this reduction-machine, it being understood that the said parts occupy such positions only when the cylinder is at rest for charging or drawing off the surplus liquid and that at other times the cylinder ro-' 'tates.

sition shown in Figs. 1 and 2 by means of a jack-like screw 56-, bearing. against either one or both of the bearing-bands 30, and by ,which means the cylinder is held ri idly in 'thesaid position and from accidenta rotary displacement. To charge the device, the -manhole-covers 26 are removed and the refuse inserted therein in any approved manner and by the use of any approved means.

When the approved quantity has been the manipulations of the va ve 45 steam isadmitted through the pipes 39 and 41 'to the.

charged within the receptacle; the manholecovers are secured firmly in osition, and by receptacle, the other valves, as 47' and 55,

remaining closed. Power is then applied at the clutch 37 to rotate the cylinder and by r-obtaining access to the space be' reason of the steam therein admitted and the agitation produced by the rotation and the bathe-plates 21 the contents is quickly digested. When sufiicient time has elapsed for the thorough digestion of the, contents, the cylinder is stopped in normalposition and the cook 24 opened, which permits the surplus liquid to flow through the pipe 23, being forced therefrom by the steam admitted through pipe 44, being a pressfactu When the liquid has ated by fluid pressure.

been drainedout tothe required extent, the valves 24 and 45 are closed and the valve 47 opened, whereby the air within the receptacle is exhausted through the pipe 46, pro-' ducing thereby a partia vacuum within the receptacle. pipes 54 and 49 to the chamber between the jacket and the cylinder, raising the temperature of the cylinder and its contents thereby, and the vapor produced by the drying process passes ofi through the pipes 41 and 46 into the vacuum-chamber. The water of condensation within the chamber between the jacket and. the cylinder is drawn "off through the pipe 51 into the trap 52in the usual well-known manner. By the use .of this machine refuse of any and every nature may be introduced therein thoroughly digested, drained, and dried without-leaving the cylinder and without opening the man- Steam is then admitted through i holes or any communication with the eXternal air: to .permit the escape of foul odors or contained figases, all of the vapors and liquid passing 0 through the pipes as aforesaid and into the usual sewer or other connection.
