To all whom it may concern:

Be it known that I, PATRICK J. HARE, a citizen of the United States, and residing at New York, in the county of N cw York and State of New York, have invented certain new and useful Improvements in Apparatus for Extracting Liquids from Garbage or Offal, of which the following is a specification, such as will enable those skilled in the art to which it appertains to make and use the same.

This invention relates to apparatus for extracting or separating liquids from garbage or offal so that said garbage or ofial may be treated in the usual manner for any purpose, and the object of the invention is to provide an apparatus of the class specified which is simple in construction, convenient of and effective in operation, and which is also comparatively inexpensive, and by means of which the said operation of separating liquids from garbage or offal may be quickly, easily and effectively performed; and with this and other objects in view the invention consists in a machine or apparatus of the class specified, constructed and operating as hereinafter described and claimed.

The invention is fully disclosed in the following specification, of which the accompanying drawing forms a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in which Figure 1 is a sectional side view of my complete apparatus with part of the construction broken away;

Fig. 2 a sectional plan view on the line 22 of'Fig. 1 with part of the construction broken away; and,

Fig. 3 a transverse sectional view on the line 33 of Fig. 1 and looking backward and on an enlarged scale.

In the practice of my invention, as shown in the drawing, I provide a strong and substantial main frame consisting of two similar side members a composed of any suitable material and connected, in the construction shown, by two transverse bolts, bars or rods a at the opposite ends and near the bottom thereof and by transverse bars a at the top thereof, but the side members a of the main frame may be formed and connected in any desired manner.

The main frame, or the'side members thereof, are provided centrally of the top thereof with a raised portion a in which are mounted two rollers b, and said raised portion a of the frame, or the side members thereof, are provided with vertically arranged slots or openings 5 over which are secured yoke-shaped brackets 5 and mounted in the slots or openings 5 are vertically movable bearing blocks 5*, and the rollers 79 are provided with reduced end portions 5 through which are passed shaft 5 the ends of which pass into the bearing blocks 5 Mounted in the yoke-shaped brackets b are threaded sleeves provided at their upper ends with nut-shaped heads 5 and at their lower ends with blocks 5 and passed downwardly through the threaded sleeves b and screwed into the bearing blocks 5 are rods 0 provided at their upper ends with handle members 0 and between the blocks 5 and the bearing blocks If are spiral springs c through which the rods 0 pass, and by means of this construction the bearing blocks o and the rollers 12 may be raised and lowered, or adjusted vertically when desired, and the springs a normally serve to depress the rollers 6 as will be understood. The blocks 5 are rotatable with the sleeves 5 and by turning said sleeves the tension of the springs 0 may be regulated.

Mounted directly under the rollers b are cylindrical drums d which are hollow in form and which are provided with end members d having hub portions (Z and shafts d are passed through said drums and through the side portions of the main frame, and the end portions d of said drums are provided with projecting flanges (i The body of the front drum d is provided with circumferential grooves 03, in the form of construction shown, and longitudinal grooves d which intersect the grooves d, and at the points of intersection of these grooves, said drum is provided with apertures (Z and the body of the rear drum cl is provided, in the form of construction shown, with longitudinal slots or openings (Z which are preferably arranged as shown in Fig. 2 so that the longitudinal slots or openings in one line will overlap those in another.

The shafts (Z* of the drums (Z are provided at the right side of the machine with gears e and at the left side of the machine with worm gears 6 and the gears at the right side of the machine mesh with similar gears e mounted on the shafts b which extend through the bearing blocks 6 at said side of the machine.

On the outer side of the left side of the machine is mounted a worm gear shaft having worms f which mesh with the worm gears 0 and the shaft f is provided centrallywith a ratchet f and the left side frame member a is provided between the rollers Z) with projecting arms 7" in which is mounted a vertically movable rod f provided at its lower end with a pawl f operated in one direction by a spring 7 to engage the ratchet f and said rod 7* is provided between the arms 7'" with a collar f between which and the lower arm f is placed a spiral spring 7 which normally serves to force the rod upwardly.

The rod f is provided at is upper end with a yoke g in which is pivoted an antifriction roller 9 and mounted on the top of the main frame and centrally of the raised portion a thereof is a transverse shaft the ends of which project at both sides of the main frame, and at the left side of the apparatus, said shaft is provided with a cam g which operates in connection with the roller g to move the rod downwardly at each revolution of said shaft 9 The shaft is provided at the right side of the machine with a pulley g and mounted transversely of the rear end portion of the main frame and in the top thereof is a shaft which carries a cylindrical brush 9 and the shaft is provided at the right side of the machine with a pulley g and mounted on he pulleys g and g is a belt h.

The shaft 9 is vertically adjustable, and this adjustment is efi'ected by screws 7L2 at the opposite ends thereof and any suitable construction to produce this result may be employed. The shaft 9 is also the main drive shaft of the machine and is provided at the right side thereof with a pulley 71/ and said shaft and the machine may be driven by a belt it operated by any suitable power device.

Mounted in the front and rear end portions of the main frame are belt conveyer rollers 2', and in the bottom portion of the main frame and slightly at the front and rear of the drums (Z are smaller belt conveyer guide rollers i and mounted on the rollers i and passing between the rollers Z and drums (Z and beneath the rollers i is an endless or belt conveyer 2, preferably composed of strong heavy fabric material, and beneath the drums (Z and between the rollers 2' in the construction shown is placed a pan j, the bottom of which is preferably inclined downwardly in the direction of the left side of the machine, and this pan is made in the form of a drawer, and may be inserted into position by passing it through the left side of the main frame, as shown in Figs. 1 and 3, and the front of said pan is provided with handles 7' and with a flexible discharge pipe j Mounted in front of the machine and pro vided, in the construction shown, with an independent support is a feeder m, consisting of a main outer barrel or casing m and a supplemental inner barrel or casing m between which is an annular chamber m The supplemental inner barrel or casing m projects through the front end of the main barrel or casing m and is provided at the front thereof with a hopper m, and mounted centrally in said supplemental inner easing m is a tubular shaft m provided with perforations m and a spiral conveyer web m and the front end of the shaft m projects and is provided with a pulley m" on which is mounted a belt 71- whereby said shaft may be turned, and the casing m is provided with a. hot water or steam inlet pipe 02 and a discharge pipe 01 and a hot water or steam pipe a extends into the front end of the shaft m, and said pipes are provided with valves a.

The back or rear end of the inner conveyer casingm is provided with a. discharge chute 0 having a discharge opening 0 the dimensions of which may be regulated by an adjustable top plate or cover 0 With the foregoing description, the operation will be readily understood in view of the following statement. The garbage or offal is fed into the feeder m through the hopper m and the conveyer shaft m being set in operation, the said garbage or offal is fed through the feeder and discharged onto thebelt i and is carried by said belt between the rollers Z) and the drums cl. During this operation hot water or steam is admitted through the pipes n and a and this aids in separating the liquids from the garbage or offal, and especially is this true when said garbage or offal contains an amount of grease. In the passage of the garbage or offal between the rollers band drums (Z, the liquids contained in said garbage or offal are extracted or separated therefrom and pass through the drums (Z, or the apertures and slots (Z and d therein and fall into the pan and may be drawn off from said pan through the pipe j and said pan may be removed and cleaned whenever desired.

The function of the brush g which is cylindrical in form is to clean the conveyer belt 2' or remove therefrom the garbage or offal after liquids have been extracted therefrom, and in the above described operation, a part of the liquids extracted from the garbage or offal will pass downwardly around the drums (Z and, as will be seen, the operation of the rollers b and drums (Z is an in termittent operation, this result being effected by means of the rod f, the ratchet f on the shaft 7, the pawl f and the cam g on the shaft 9 and this operation also facilitates the extraction of the liquids from the garbage or offal by reason of the fact that the said garbage or ofial remains longer under compression as it passes between the rollers Z) and drums (Z, but my invention is not limited to this intermittent motion of the parts referred to, nor to the exact details of the construcion herein shown and described, and the feeder m may be mounted in connection with the main frame, if desired, and other changes in and modifications of the construction herein shown and described may be made, within the scope of the appended claims, without departing from the spirit of my invention or sacrificing its advantages.
