LARD-PRESS.

Specification of Letters Patent.

Patented Oct. 8, 1907.

Application filed April 25,1907. Serial No. 370,214.

To all whom it may concern:

Be it known that I, EMMA A. SPROAT, a citizen of the United States of America, residing at Waynesburg, in the county of Greene .and State of Pennsylvania, have invented certain new and useful Improvements in Lard-Presses, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to lard presses, and the invention has for its object to provide a press wherein positive and reliable means is employed for extracting cooked lard from the cracklings of pork or the fats of other animals. 7

My invention aims to provide an efficient press particularly designed for household use, although the press can be constructed upon a larger scale to adapt it to abattoirs and slaughter houses.

The press consists of a housing of rolls adapted to be manually revolved, and in connection with the rolls, I use a spout for conveying the extracted lard to a suitable receptacle, the cooked lard or cracklings being fed between the rolls, whereby it will be thoroughly pressed and the available lard extracted from the crack-lings.

The detail construction entering into my invention will be hereinafter more fully described and then specifically pointed out in the appended claims.

Referring to the drawing forming part of this specification, like numerals of reference designate corresponding parts throughout the several views, in which Figure 1 is a side elevation of my improved press. Fig. 2 is a front elevation of the same, Fig. 3 is a detail sectional view of one of the rolls of the press.

In the accompanying drawing, 1 indicates a suitable support, as a table, upon which the press is placed.

The press comprises a pair of standards 2, suitably secured to the support or table 1, as at 3.

Journaled in the standards 2 near the lower end thereof is an operating shaft or spindle 4 upon which is mounted a roll 5, covered with metal or anon-absorbent material 6. One end of the shaft or spindle 4 protrudes beyond one of the standards and is provided with a crank handle 7 whereby a rotary movement can be imparted to the roll 5. The standards 2 are slotted, as at 8, to accommodate bearing blocks 9 in which are journaled a shaft or spindle 10 carrying a covered roll 11 similar to the roll 5. The bearing blocks 9 are supported upon springs 12 within the standards and said blocks are adjusted by screws 14 mounted in the standards 2 and engage the bearing blocks 9. The proclivities of the spring 12 are to force the roll 11 upwardly and away from the roll 6, therefore by adjusting the screws 14, the roll 11 can be moved into as close proximity to the roll 5 as desired. In connection with the rolls 5 and 11, I use a combined collecting and conducting member 15 having the forward portion thereof projecting so as to form a spout, which is suitably secured as at 16, to the front edges of the standards 2, the spout protruding over the edge of the support or table 1. The rear edge of the member 15 extends upwardly under the roll 5 as at 17, whereby the drippings from the rolls will be conveyed to the front end of the member 15. I have also illustrated a receptacle 18 and a bag 19 as being used in connection with the press, the latter serving functionally as a strainer for lard. In practice, the'bag 19 is suitably supported in the receptacle 18, while the cracklings are being placed therein. After the bag 19 has been suitably filled with cracklings, the end of the bag is passed upwardly through the member 15 and inserted between the rolls 5 and 11. As the roll 5 is rotated through the medium of the crank handle 7, a rotary movement will be imparted to the roller 11, and these two rolls are adapted to compress the cracklings within the bag 19 and cause a seepage of the lard through the bag, the extracted lard passing down the spout 15 into the receptacle 18. In this manner the cooked cracklings can be subjected to considerable pressure, whereby a thorough extraction of lard from said cracklings can be accomplished. The bag 19 is preferably placed in the receptacle 18in order that should there be any drippings from the cooked cracklings prior to pressing the same, the drippings can be saved.

My improved lard press can also be used for other purposes, as making cottage cheese, or any substance where liquid is to be extracted.

What I claim and desire to secure by Letters Patent, is:-

A lard press comprising a support, a pair of standards carried thereby, rolls journaled in said standards, one above the other, each of said rolls covered with a non-absorbent material, means for vertically adjusting the upper of said rolls, a handle connected with the lower of the rolls for revolving it, and a combined collecting and conducting member having the rear portion thereof cut away so as to extend below the lower of the rolls and abut against the front face of the standard, said member having the forward portion thereof contracted to form a spout, said forward portion projecting from the front of the support, combined with a hold-fast device extending through that part of the member in proximity to the standards for fixedly securing said member to the standards.

In testimony whereof I affix my signature in the presence of two witnesses.
