IMPROVEMENT IN LARD-PRESSES.

Specification forming part of Letters Patent No- 179,6l5, dated July 4, 1876; application filed April 6, 1876. i

To all whom it may concern:

Be it known that I, CHARLES J OHN SCHIL- LER, of the city of Baltimore, in the State of Maryland, have invented certain new and useful Improvements in Presses for Lard and' other Articles and I do hereby declare that the following is a full, clear, and 'exact description thereof, which will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to theletters of reference marked thereon, which form a part of this specification.

My invention relates to presses forlard and other articles to the pressing of which it is adaptable; and consists in certain improvements in the construction of the same, as hereinafter more fully shown and described. In the accompanying drawing, forming a part of this specification, Figure l is a plan view of my improved press. Fig.2 is a front elevation of the same. Fig. 3is a vertical section. Fig. 4 shows the clamp indicated by U, herein detached. Fig. 5 is a sectional view of the hand-wheel and worm-wheel herein described, and marked, respectively, G and B.

In the saiddrawing, A designates a worm, formed upon a shaft, F, having bearings D and K on the top of the construction, said shaft F being provided with the power-wheel O. B indicates a gear-wheel, which engages with the worm A, and immediately above wheel B is placed the hand wheel G, as. shown. The cross-beam M rests upon t-hesupports 0, connected with the body of the press P, the whole being supported by the legs Q. The said cross-beam is provided with a nut, N, and has an aperture through the center for the passage of the vertical screw H, with which the said nut N engages.

As shown in the drawing, the screw H also passes through apertures in the worm-wheel B and hand-wheel Gr, connection being es-' tablished between the screw and said wheels by means of the gib or key I, placed in the keyseat g, Fig. 5, formed within the said two. wheels, said key projecting into the keyway J, formedin screw H, and extending from end to end thereof, as shown in Fig. 2.

The clamp U is made in two parts, as shown in Fig. 4., the same being bolted to the crossbeam M, and formed to enter the groove m in wheel B, so that the wheels B and G, being combined by the key I, are held in position by the said clamp, which prevents their being displaced by the screw H in its movement. Thus the screw H is allowed to pass freely through wheels B and G, and engages only with the nut N in its passage through the cross-beam.

is a valuable addition, as the power of the press is greatly increased by the use of the lever in operating the screw H, through the worm A and wheel B. The bearing D ofsaid shaft F is usually made twice as long as the worm A, to allow the latter to be turned out of gear from worm-wheel B, this being effected by reversing the movement of wheel (J. The said hearing has within it a steel plate, 0, against which the shaft F presses, the end of the shaft being also of steel. R is the pressplate, which is coupled to the screw H at its lower extremity, the pl'essingsurface of said plate being provided with pins 1", which assist in the withdrawing of the crackling or mass from the basket after the operation of pressing.

In Fig. 2 is shown the crackling or mass, (indicated by 'S,) clinging to thepress-plate as it is being raised from the basket, and this withdrawing of the mass is very important in the pressing of lard or oil cake, as it saves a great deal of labor. The basket T, of metal or any suitablematerial, is made in two halves, hinged together at c, and coupled together at d by the fastening device shown in Fig. 2. Said fastening consists of the pieces at and d. pivoted at 0, to one part of the basket, and connected by the upright piece f. The said pieces 61 and d are made to close on the pins 8, fixed to the other half of the basket, and

The worm shaft F is provided with a ratchet attachment and lever, L, which the plate R by means of a swivel-joint, as shown in the drawing, the clamping part m being made in two parts, and bolted to the press-plate, so that the screw is turned without turning the press-plate. Within a recess in the press plate receiving the lower extremity of the screw, as shown, is placed a steel plate, V, the end of the screw pressing against it being of the same material. The nut N may be made solid with the cross-beam M, or it may be made detachable, as shown in the drawing, so that it may be renewed when worn.

It will be observed that the screw H may be rapidly operated by means of the handwheel G only, the Worm A being out of gear, and the power may be greatly increased by using the worm shat't, provided with handwheel (1, and ratchet and lever L.

Having described my invention, I claim-'- 1. The combination of the hand-wheel Gr, worm-wheel B, gib I, clamp U, and screw H, as set forth.

2. In combination with screw H and wheel B, keyed as shown, the worm-shaft F, having the worm A thereon, and provided with handwheel (J, as shown.

3. In a press, the combination of wheel B and the worm-shaft in the bearings D and F,

said shaft being provided with hand-Wheel C, and ratchet and lever L, as specified.

4. The pressing-screw H, provided With the keyway J, in combination with the Wheels G and B and gib I, as described.

5. The screw H and press-plate R, the iatter being coupled to the screw, as shown, and provided with the projections rfas set forth.

6. The basket T of the press, the two parts being hinged and coupled together, provided with the removable perforated plate a, as shown.

7. The press-basket T, the two parts being hinged together, and also provided with the fastening worked by the handle a and connecting-pieeef, as shown and described.

8. In a press, the combination of the basket T, made in two parts, coupled together, and provided with plate a, the grate-bars b, and the fountain W, as shown, for the purpose set forth.

In testimony that I claim the foregoing as my own I affix my signature in presence of two witnesses.

CHARLES JOHN SCHILLER.
