FR U IT-PITTVI NG MACH IN E.

SPECIFICATION forming part of Letters Patent No. 407,965, dated July 30, 1889- Application filed september 21, 1888- Serial No. 286,026. (No model.)

To all whom it may concern:

Be it known that I, JOHN ROSASSCO, of Healdsburg, in the county of Sonoma, State of California, have invented an Improvement in Fruit-Fitting Machines; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to that class of fruitpitting machines in which the fruit rests upon a properly apertured and slitted bed, and a vertically-movable spring-controlled punch provided with side knives or cutters is brought down upon the fruit, whereby its flesh is cut and its stone or pit is driven out through the bed.

My invention consists in certain improvements in this class of machines and in the combination of parts hereinafter fully described.

Referring to the accompanying drawings,

&c., Figure 1 is a perspective view of my fruitpitting machine. Fig. 2 is a section of the base-plate.

A is the baseplate, having formed therein a socket-seat a, having three beveled side flanges a and a central aperture 0 with side slits a B is a rubber cushion havingits edges beveled correspondingly to the flanges of the socket-seat a and adapted to fit in said seat. In this cushion is made a central aperture 1), with side slits b, said aperture and slits corresponding with the aperture and slits in the seat a. Around the central aperture of the cushion is a recessed. seat b for receiving the fruit.

O is a standard from which the gnidearms D project at right angles.

E is a bent rod having a long arm e and a shorter arm 6, the lower end of which forms apunch, (represented by 6 Both arms of the bent rod pass through and are guided in the arms D, while the longer arm also passes through the bed-plate A, and may have attached to its lower end a treadle-connection, whereby the machine may be operated by the foot, if desirable.

F is a hand-lever, which is pivoted by pin f to the top of the bent rod E. The rear end of this lever is fulcrumed at g in the upper ends of the links G, the lower ends of which are pivoted to the back of the standard near its base. Said links thus form a fulcrum-for the lever, and being themselves pivoted at their lower ends provide for the proper movement of the lever, so that it will direct its power to move the bent rod E perpendicularly.

H is a spring, here shown as made in two independent parts, one being on each side of and conforming to the general direction of the upper portion of the links and the rear portion of the lever. The lower ends of the springs are attached fixedly to the upper end of the standard, while the upper ends are at-' tached to the upper end of the bent rod E, preferably upon the pin f, which pivots the lever to said rod.

The punch e of the short arm of the rod is slitted, and into this slit is let and secured the bent knife or cutter I, so that one-half of the knife passes downwardly on each side of and below the lower 'end of the punch.

The base or bed plate A of the machine .is adapted to be screwed to the table, so as to hold it in proper position.

The operation is as follows: The fruit is placed on end within the recessed seat 11 of the. rubber cushion. The leverF is then forced down, so as to force down the bent rod E, which movement first brings the wings of the knife I into contact with and cuts the flesh of the fruit, while the punch e comes down on top of the pit and forces it dowm'vardly through the central aperture of the cushion and of the socket-seat of the bed-plate, the slits in the cushion andin the socket-seat of the bed-plate receiving the wings of the knife. WVhen the lever is relieved, the spring returns the bent rod for the repetition of the operation. The rubber cushion being fitted to the base-plate, as' described, renders it easily removable to be cleaned and another substituted when desired. The recessed seat b in the cushion provides for the proper holding of the fruit under operation. The bent winged knife I properly cuts the flesh. of the fruit, so that the pit or stone is sufficiently freed to be driven out without bruising the fruit.

The arrangement of spring as herein described is simple and effective, and is less liable to get out of order than the spiral spring encircling the rod, as has heretofore been customary. The lever-connection having the va riable fulcrum is of advantage in providing a simple power device for imparting a perfectly vertical or perpendicular motion to the bent rod.

Having thus described my invention, what I claim as new, and desire to secure by Letters 10 Patent, is'

An improved fruit-pitting machine consisting of the combination of a bed-plate having an apertured and slitted socket-seat with beveled surrounding flanges and a fixed standard with guide-arms, a cushion having beveled sides fitted in the socket-seat and having an aperture and side slitsand a recess-seat for the fruit, a vertically-movable bent rod In witness whereof I have hereunto set my 30 hand.

JOHN ROSASSCO.
