Letters Patent No. 95,038, dated September 21, 1869.

W mznoven MEAT-CUTTING- MACHINE.

The Schedule referred to in these Letters Patent and making part: or the same.

To all whom it may concern.-

Be it known that I, Aueus'r N rr'rmenn, J r., of thecity and county of Philadelphia, and State of Pennsylvania, have invented a new and useful Improvement in Meat-Cutting Machines; and I do hereby declare that the following is a full, clear, and exact description thereof, reference being bad to the accompanying drawings, and to the letters, of reference marked thereon.

This is an improvement on the meat-cutting machine patented by me, under date of August 11, 1863, in which a rotary table or block is combined with reciprocating knives, and theJsaid knives so arranged on the cross-head that they can. be readily sharpened, and the edges preserved. I Mypres'ent improvement consists in securing on the inside of the framing triangular-shaped guides, so as to carry the cross-heads steady and straight in their up-and-down movements; also,'h0lding the knives by a peculiar arrangement of spring-catches, so that they can be readily sharpened. The spring-catches also secure the guides in proper position when the knives are in operation.

Figure 1 is a side elevationof my improvement, with a portion of the table or' block-rim removed.

Figure 2 is an end elevation of same, with the knives turned into positionready for sharpening.

To enable those skilled in the art to make and use my invention, I will now proceed to describe its construction and operation.

Secured to the bed-plateB of the machine are two frames, F and F, which are connected together at their upper ends, by means of the plate P.

Secured in the centre, and underneath the plate P, is an upright, U, which extends down within a short distance of the table or block 1.

The main driving-shalt S is formed with two cranks, O and G, whiclrwork in bearings E, E, and

Bearings E and E are secured to the interior and at the upper part of the franresh and F, and the.

bearing E is secured to the upright U, on a line with bearings E and E En'circling each bolt which holds the caps of the bearings E,,E, and E in place, are spiralsprings, A A A,flthe lower ends of which bear on the caps, and the upper ends come in contact with the nuts placed verthe ends of the bolts, so that in case any bones should be placed on the block with the meat,

the sharp edges of the knives, in striking them, will cause the shaft to raise .inthe bearings, and thus act as a. cushion for the knives, and prevent their breaking or becoming dull. I

Connected to the cranks G and G are two r0ds, R and R", on the lower ends of whieh'are pivoted crossheads H and H, which work on and are guided in their up-and-down movements by triangular-shaped guides, G, G, G, and G, which are pivoted at their upper ends to the inner sides of the flames FandF', and to the sides of the upright U.

Guides G, G'LG, and-G are held in place by means of spring-catches K and K and reyolving-plate L. V

,The knives 1, 2, 3, and 4 are attached to and adjus'ted on the cross-heads H and H, in the usual manner. I

When it becomes necessary to sharpen the knives, the cross-heads are'turned until the knives assume ,a horizontal position, as shown infig.'2. In this posi-' tion they are retained by means of a spring-catch, K secured to the front of the frames E and F.

Having thus described my. invention, its construction and operation,

What I claim, and desire'to secure by Letters'Pat- 'ent of the United, States, is-

The arrangement ofthe upright U, triangular-shaped guides G, G G and G, spring-catches K, K, and K, and plate L,.substantially in the manner and for the purpose specified.

In testimony whereof, I have hereunto signed'my name, in the presence of two subscribing witnesses.

AUGUST NITTINGER, J R
