RENDERING-TANK.

Application filed September 27, 1918.

To all whom it may concern:

Be it known that I, LEBOVICS IVLARTON, a

- citizen of the United States, residing at Terre Haute, in the county of Vigo and State of Indiana, have invented certain new and useful Improvements in Rendering- Tanks; 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 it appertains to make and use the same.

This invention relates to rendering tanks or apparatus and has for its object toprovide a means of this nature which will be comparatively inexpensive to construct, and more certain and simple in action than those which have been heretofore proposed.

With these and other objects in view the invention consists in the novel details of construction, and combinations of parts, more fully hereinafter disclosed and particularly pointed out in the claims.

Referring to the accompanying drawings forming a part of this specification in which like numerals designate like parts in all the views Figure 1 is a vertical sectional view of an apparatus made in accordance with this invention;

Fig. 2 is a cross sectional view taken on the line 2-2 of Fig. 1, looking in the direction of the arrows;

Fig. 3 is a cross sectional view taken on the line 33 of Fig. 1, looking in the direction of the arrows;

Fig. 4 is a cross sectional view taken on the line H of Fig. '1, looking in the direction of the arrows;

Fig. 5 is a perspective view of the perforated press member detached from the apparatus; and

Fig. 6 is a diagrammatic detail perspective view of a portion of the parts shown in Fig. 5, illustrating the pivoting members 30 in their operative position.

1 indicates any suitable power pulley for rotating the shaft 2 and pinion 3 which meshes with the bevel gear 4 rigid with the nut 5, mounted on the press frame 6 supporting said shaft 2. Said frame is in turn supported by the standards 7, passing through the upper flange 8, and the lower flange 9 of the tank 10 provided with the bottom 11, and steam jacket 12 surrounding said bottom as shown.

Passing upwardly through said bottom and steam jacket is the short shaft 13 on the Specification of Letters Patent. Patented Dec, 241:, 1918,

Serial No. 255,945.

upper end of which are mounted therotating knives 14. Below'said jacket is mounted on said shaft 13 the bevel gear 15 meshing with the pinion 16 carried by the shaft 17 on which is mounted the power pulley 18, as shown. 20 represents a steam inlet and 21 a steam andwater outlet.

Fitting the interior 25 of the tank 10 are the vertically disposed ribs, rods or spacers 26 made of any desired form, and rigid with the perforated vertically moving press member 27 leaving a space 28 between its outer surface and the interior 25 of the tank 10. Said perforated press member is conveniently made in two parts hinged together as at 28, which are outwardly flared as at 29 to fit the interior 25 of the tank 10, for a purpose that will presently appear. Near the lower edge of the press member 27 and on the interior thereof, are located the lifting members 30 hinged to the interior of the member 27 as at 31, see Fig. 6. Said lifting members 30 are capable of being swung up into the positions shown in Figs. 1 and 5, or they can be swung down as shown in Fig. 6, whereupon their right angular extensions 33 will contact with the member 27 and hold the lifting members 30 in their horizontal positions.

Around the top rim of the compressor member 27 are the turned over lips 35, be neath which are located the disk like lifting and compressing member or press plunger 36. Said plunger member 36 is secured to the screw 37 which passes upwardly through the nut 5, and which may not rotate. On top said lips 35 contact with the holding or' clamping member 40 through which said screw 37 also passes, and which is held in its clamping position by the nut 41. 42 represents a vent or gas escape pipe; while 43, 44, 45 and 46 represent pipes for carrying off water and grease, the, last two passing through the steam jacket 12 as illustrated.

In addition to said

pipes

43, 44, 45 and 46, I provide a plurality of pipes 46 which I call cookers. These pipes 46 are preferably three in number, only one being shown, and their function is to supply live steam to the meat and cook the same as will be readily understood. In addition to supplying steam through said cookers 46 I may also supply live steam through the pipe 46 by means not shown when the latter is not carrying off water and grease.

50 represents a cover for the tank 10, conveniently hinged as at 51, and provided with the handle 52. The operation of my invention will be clear from the foregoing but may be briefly summarized as follows After operating the shaft 2 to lift the press member 27 entirely out of the tank 10, either Whole carcasses or portions thereof may be placed in said tank whereupon the materials are subjected to the action of the knives 1 1 while the cover 50 is closed and steam is turned on. After the meat material has been thus cooked, the cover 50 is lifted, the pulley 1 reversed and the press lowered to force out the fats from the mass. During the lowering of the press member 27, its flanges 29 fitting the interior of the tank will press down the cooked material, and will force any bones or other like solids toward the center, thus enabling the said flanges 29 to substantially reach the bottom of the tank 10.

The placing of animals or other material into the tank 10 is or may be facilitated by locating the flange 8 of said tank flush with a'sloping surface 7 5 of a floor as indicated in Fig. 1. In other words, the animals may come directly from the skinning or dismembering floor, and be thrown directly into the tank 10.

It is an important feature of the invention that the steam jacket 12 is located on the outside of the tank 10 instead of on the inside, for its outside location enables one to provide a continuous smooth interior of the tank for the press to traverse, and therefore, to greatly increase its capacity over what the latter would be if the jacket 12 is located on the inside of said tank.

While the member 27 is descending the hinged lugs 30 occupy the positions shown in Figs. 1 and 5, but when the press is ascending they automatically assume the position shown in Fig. 6, andthus enable the press to lift out of the tank the cooked compressed mass.

After the flanges 29 reach the bottom of the tank the clamping member 10 may be turned by any suitable means to one side to clear the lips 85, whereupon a continued motion of the pulley 1 will cause the plunger 36 to descend independently of the member 27 and thus to compress the cooked material to any desired degree. During the above described operations, the fats, etc, that have been expressed from the cooked material will pass through the perforations 55 in the member 27. The fluids passing through the perforations 55 will enter the spaces 28 and pass down to the bottom of the tank, to be forced through the pipes 45 and 16. But, the grease during the close of the operation will of course mainly pass through the pipe 46. After all the grease has been thus recovered the cooked and pressed material may be lifted by again reis facilitated by reason of the member 27 being hinged. That is to say,when said member containing said material is raised sufliciently above the flange 8, a truck may be backed over said tank withits wheels resting-on said flange on each side of said tank, and the member 27 holding said compressedmaterials may now be opened out, or turned on its hinge whereupon said material will drop into said truck and becarted away. In case it is desired to dry thecompressed material, or materials, it may be conveniently dumped back into the tank 10 from the truck, whereupon the cover 50 may be closed and steam turned into the jacket 12. lVhile the material is drying it is best to continuously rotate the cutting and agitating device 14:, andthis said device 14 may also be rotated to force the material out of the opening 65.

It will be observed that I have left a considerable space 7 7 between the bottom of the tank and the bevel 15 so that said bevel may lift against the weight of the parts when the cutting means 14 strikes a bone and thus disengage its teeth from the driving pinion 16. After passing the obstruction said bevel and pinion automatically retank 10 may be entered near its'bottom and 66 represents a suitable closure for said opening.

It is obvious that those skilled in the art may vary the details of construction as well as the arrangement of parts without departing from the spirit of the invention, and therefore, I do not wish to be limitedto the above disclosure except as may be required by the claims.
