UNITED STATES PATENT OFFICE.
OLIVER METCALF, OF MITCHELL, ASSIGNOR TO JOSEPH HARLAN, OF
LEXINGTON, INDIANA.
IMPROVEMENT lN FRUIT-PRESSEQ.
Specification forming part of Letters Patent No. 139,785, dated Apiil 15, 1873; applitation filed December 20, 1872.
To all whom it may concern:
Be it known that I, OLIVER MEroALF, of Mitchell, in the county of Lawrence and State of Indiana, have invented certain Improvements in Fruit-Presses, of which the following is a specification: V
My invention relates to that class of presses intended for family or household use, but is not confined to any particular size. An important feature consists in the method of attaching the forked piston-rod to the piston. Draw mg.
Figure 1 is a longitudinal vertical section of my press on the plane of the line as a; in Fig. 2. Fig. 2 is a plan of the press. Fig. 3
is a sectional view of the piston, showing the The outer and inner perforated cylinders D and E' have an annular space between them for the reception of the fruit to be pressed, and a perforated piston, F, fitted to this space, serves to press out the juice. The piston F.,receives a vertical motion through the medium of a forked piston-rod, G, bear: ing a rack, H, on its upper extremity, which meshes with a pinion, I, on a shaft, J, said shaft having bearings in the uprights L L. A hand-wheel, M, is the medium for applying power. To keep the rack H up to the pinion, it is guided by the bearer N. To prevent the reaction of the piston durin g the intervals of intermittent motion downward, I use a ratchet, b, on the shaft J, and a pawl, c, which acts as a detent or stop. The pawl is disengaged to allow the piston to be raised.
The use of a central cylinder in the chamber necessitates forking the piston-rod; and to render it easily detachable from the piston,
' one branch, 1?, (see Fig. 3,) is made separate,
and attached to the rod by a bolt and nut,
form of the lower extremities of the forks or branches, and the corresponding openings in the piston for their reception, will be readily understood from Fig. 3.
By the use of an interior perforated cylinder, which is located in the center of the crushed mass, an interior exit is allowed for the juice; and a similar advantage may be claimed for the perforated outer cylinder and the perforated piston. As a whole, the press presents an exceedingly large perforated area to the crushed mass, which is very desirable.
For the sake of perspicuity in the drawing, the perforations are represented larger in size and less in number than the reality.
The juice when pressed out finds it way into the vessel 0, and thence through the large openings in the interior cylinder down through the tube a into any desired vessel.
When it is desired to take the press apart and clean it, the piston is raised to its full height and the chamber slipped from under it, the slot B permitting the passage of the tube a.
If thought necessary, the outer cylinder can be removed from its bottom, so as to be the more readily cleaned.
Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
1. The inner perforated tube I), provided with a projection, a at its lower extremity, for leading off the e pressed juice to a proper receptacle, substantially as shown and de= scribed.
2. The device for attaching the piston F to therod G, consisting of a detachable branch, P, and the hooked form of both branches at their lower extremities, substantially as shown.
3. In combination with the elements of the above-described press, the slotted base A, constructed substantially as shown,..and for the purposes set forth.
Witness my hand this 5th day of Decem ber, 1872.
OLIVER METGALF.

WILLIAM H. DAVIS, GEORGE L. MERGER.
