UNITED STATES PATENT OFFICE.

RUFUS'E. BOSOHERT, OF SYRACUSE, NEW YORK.

APPARATUS FOR TREATING GARBAGE.

SPECIFICATION forming part of Letters Patent No. 700,727, dated May 27, 1902. Application filed September 9,1901. Se ial No. 74,743. (No model.)

To all whom, it may concern:

Be it known that I, RUFUS E. BOSCHERT, a citizen of the United States, and a resident of Syracuse, in the county of Onondaga, in the State of New York, have invented new and useful Improvementsin Apparatus for Treating Garbage, of which the following, taken in connection with the accompanying drawings, is afull, clear, and exact description.

This invention relates to the class of apparatus which are employed for separating oils and liquids from solid matter in garbage; and it has more particularly reference to the apparatus shown in my prior application for patent, Serial No. 52,962, filed March 26, 1901.

My present invention consists in certain improvements of the details of construction which in some respects simplify the apparatus and increase the efficiency thereof, as hereinafter explained, and as illustrated in the accompanying drawings, in which- Figure l is a side elevation of my improved apparatus. Fig. 2 is a vertical longitudinal section of the same; Figs. 3, 4, and 5, top plan views of, the interiors of the three portions of the apparatus, indicated at A, B, and O in Fig. 1. section on line X X in Fig. 4:. Fig. 7is a vertical transverse section on line Y Y in Fig. 6', and Fig. 8 is an enlarged end view of the feeding portions of the two feeding rollers.

D represents the ohamber,which completely incloses the devices for separating oils and liquids from the solid matter of garbage and is sufficiently air-tight to prevent escape of gases and odor from the interior of the chamber.

E denotes the hopper, which is connected to one end of the chamber D and delivers the garbage from the usual digester (not shown) to the feed-rollers F F, which extend across the end of theinterior of the chamberD and are mounted in suitable journal-boxes in the sides of the chamber. The journal-boxes s of one of said rollers are supported movably on longitudinal guides t, and by means of springs 3, bearing on the sides of said boxes, the roller supported therein is forced toward the opposite feed-roller and is allowed to yield to the pressure of hard substances passing between the rollers. The end portions of these rollers are smooth to allow the hopper to be fitted closely thereto. To augment the Fig. 6is a vertical longitudinal,

efficiency of theIfeed-rollers, I corrugate them longitudinally in such a manner as to cause the ribs of the two rollers to coincide in their positions and meet diametrically opposite each other and form directly overthe meeting ribs a pocket t, extending lengthwise of the bite of the rollers, as illustrated in Fig. 8 of the drawings. Said pocket allows the material to freely pass from the hopper to the bite of the rollers, from whence it subsequently drops onto the subjacent conveyer during the rotation of the rollers. The feeding of the apparatus is thus rendered more positive.

p The feed-rollers F F are caused to rotate in unisonby means of intermeshing gears 26 t attached to the shafts of said rollers. A sprocket-wheel t is attached to the shaft of one of the feed-rollers and connected by a chain 25 to a sprocket-wheel t, which is attached to a transverse shaft 16, mounted in bearings on top of the chamber D. Parallel with the shaft 29* and in proximity thereto is a rotary shaft 27, to which is attached a pin,- ion i meshing with a gear 15 secured to the shaft if. .The feed-rollers thus receive motion from the shaft 15 To allow the speed of feeding to be regulated according to the degree of moisture or density of the material in transit to the conveyer, I employ suitable variable gears for transmitting motionto the feed-rollers. This may be accomplished by means of a cone-pulley P, attached to the shaft 6 and connected by belt P to a reversely-disposed cone-pulley P on the main driving-shaft.

It represents the longitudinally-traveling conveyor, which extends from end to end of the interior of the chamber D and receives the garbage from the feed-rollers F F, said conveyor consisting of draining-slats d d, attached transversely'to sprocket-chains a a, carried on sprocket-wheels G G, arranged in the end portions of the chamber. To maintain the chains a a at the requisite tension, one of the sprocket-wheels has its journalboxesb mountedin longitudinal guides b and sustained adjustably in their positions by means of screws 0. The conveyor R is sup ported at intervals of its length by means of transverse rollers I I, disposed directly under the conveyor and having their shafts protrud ing at the sides of the chamber. These supporting-rollers are formed with circumferential grooves e for the passages of the chains a, and in said grooves are teeth e engaging the chains. The rollers I I are also provided with circu mferential grooves f, through which pass longitudinal barsf, supported on transverse bars g, seated on brackets 71, adj ustabl y secured to the sides of the chamber. The barsf serve to support the slats d of the conveyer.

To the ends of the shafts of the rollers I I are fastened gear-wheels J J,arranged in pairs meshing with an intermediate rotary pinion J The rollers are thereby caused to rotate in unison. Over each of these supportingrollers is a series of compressing-rollers Z Z, which are disposed contiguously side by side and are separate and revoluble independently of each other and ride by gravity on the conveyer. The compressing-rollers of each series I prefer to arrange with the centers of their treads in paths intermediate the paths of the adjacent series of compressing rollers, as shown in Figs. 3 and 4. These compressingrollers are maintained in their positions over the supporting-rollers I I by means of suitable guards arranged in'front and rear of each series of compressing-rollers. I preferably form each of said guards of a series of separate and independently-movable rollers ti,

' mounted loosely upon a shaft 71, extending across the chamber and secured to the sides thereof. The guard-rollers 71 2'- are placed in positions to bear on the rear of the compresthe conveyer, as illustrated in Fig. 6 of the drawings.

1' 1" denote perforated pipes for spraying water over the garbage carried on the conveyer, and thereby expedite the expulsion of oily substances.

n represents a brush arranged to clean the top of the conveyor after it has passed beyond the compressing-rollers.

What I claim is- 1. In combination with the supportingroller, a series of separate and independentlymovable compressing-rollers disposed contiguously side by side, and guards disposed to engage the front and rear peripheral faces of the compressing-rollers to maintain said rollers in operative position over the supporting-roller as set forth.

2. In combination with the supportingroller, a series of separate and independentlymovable compressing-rollers disposed con tiguously side by side, shafts disposed in front and rear of said compressing-rollers and parallel with the axis of the supporting-roller, and a plurality of guard-rollers mounted revolubly independent of each other on said shafts and arranged in series corresponding to the series of compressingrollers and in range therewith as set forth.

4. The combination with the longitudinallytraveling conveyer provided with ducts for draining the superposed material and a plurality of rollers supporting said conveyer at intervals of its length, of compressing-rollers riding by gravity upon the conveyer, and guards disposed to engage the front and rear faces of the compressing-rollers and maintain said rollers in operative positions over the supporting-rollers as set forth.

5. The combination with the longitudinallytraveling conveyer provided with drainingducts, and a plurality of rollers supporting said conveyer at intervals of its length, of a corresponding plurality of series of compressing-rollers riding by gravity upon the conveyer, the rollers of each series being disposed contiguously side by side and revoluble independent of each other, shafts disposed between the successive series of compressing-rollers and parallel with the supporting.-rollers,and a corresponding series of separate and independently-revolubleguard-rollers mounted on each of said shafts as set forth.

6. The combination with the longitudinallytraveling conveyer provided with drainingducts and a plurality of rollers supporting said conveyer at intervals of its length, of a corresponding plurality of series of separate and independently-revoluble compressingrollers riding by gravity upon the conveyer, the rollers of each series being disposed contiguously side by side and with their treads in lines intermediate the treads-of the adjacent series, shafts extending between the successive series of compressing-rollers and par allel with the supporting-rollers,'and guardrollers mounted on said shafts and revoluble independently of each other as set forth.
