WILLIAM R. PHILLIPS, 0F TRENTON, NE'W JERSEY.

APPLE-PARING MACHINE.

To all whom it may concern:

Be it known that I, IVILLIAM R. PHILLrrs, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain new and useful Improvements in Apple-Paling Machines, of which the following is a specification.

My invention relates to iniprovements in machines for slicing and paring fruit of a certain kind, as apples, pears, peaches, and the like, as well as for coring the same, also for peeling and slicing potatoes.

Said invention has for its object to secure the aforesaid results in a simple and effective manner and to promote simplicity, as well as to cheapen manufacture.

It therefore consists of sundry features or instrumentalities substantially as hereinafter fully disclosed and specifically pointed out by the claims.

In the accompanying drawing illustrating the preferred embodiment of my invention- Figure l is a side elevation thereof. Fig. 2 is an opposite side elevation of the same. Fig. 3 is a plan View thereof, and Fig. l is a sectional elevation produced transversely through the machine. Fig. 5 is an end elevation thereof. Fig. 6 is a detached perspective view, taken from the underside of the guide-bar. Fig. 7 is a detached perspective view of the knife carriage. Fig. 8 is a view showing the machine equipped for the treatment of vegetables as potatoes for slicing the same.

In carrying out my invention, I mount the operative parts thereof upon a suitable f ame or casting l adapted for retention in rigid position at any convenient point as will be readily understood.

A screw or worm shaft 2 suitably journaled in position and intergeared as at 3 with a crank or handle is equipped with an interiorly toothed gear-wheel il. Said shaft has mounted so as to travel thereon a carriage 5, the latter having alining openings with a sleeve G between said openings for the passage through the same of said shaft but not having screw-threaded engagement therewith. Said carriage has a downward extension 7 having in its lower end a notch receiving an edgewise-arranged rib er rail 8 integral with the frame or casting l for the effective guidance and stability of said carriage. Also said carriage .is equipped with, and carries a paring knife 9 preferably of Specification of Letters Patent.

Application filed April 25, 1907.

Patented Apr. 5, 1910. Serial No. 370,283.

the construction disclosed, comprising a flat surfaced block or head l0 rounded at its forward edge, and a curved edgcwise-arrangcd blade l l having its ends suitably secured to said head by a screw-bolt and conformable to the rounded forward edge thereof but outstanding from the latter sufficiently for effecting the paring of the fruit as it is juxtaposed thereto in the usual way. A stem or rod l2, to which said block or head is held by a set-screw 13, has a right-angled lower end-portion pivoted in an aperture in the corresponding portion of the extension 7 of the carriage 5; and said stem or rod l2 is controlhid by preferably two helical or coiled springs 1.1L connected thereto and to said carriage, holding said stem forcibly against the latter and the knife in effective position. Said stem or rod is also equipped with a cam projection l5 extending in under the top-plate of the carriage 5, the function of which will be made apparent later.

A handle-equipped dog 16 suitably pivoted to and carried by the carriage 5, has its effective inner portion adapted for engagement with the screw shaft 2, also with a guide or holding bar later described, said dog being, however, normally held automatically out of such engagement with the parts noted by the action of a preferably coiled spring 17. Said spring is adapted to exert downward pressure upon the outer arm of said dog for that purpose, it receiving at its upper end a stud or pendant 18 of said dog and receiving at its lower end an upstanding terminal of a plate or bracket 19 held preferably by a bolt or screw to the underside of the carriage 5. The dog 16 has an integral lateral extension or arm 20 for engagement with the cam-projection 15 on the rod 12 for affecting the action of the paring knife as will be later' seen. The carriage has connected thereto in any suitable way one end of a preferably coiled or helical spring 2l, connected at its opposite end preferably to a thumbscrew 22 threaded into the frame l and which may serve for compensating tension of the spring as required, said spring being designed to provide for automatically returning the carriage to its initial position after performing its forward movement as will presently appear. A stop 23 preferably in the form of an edgewisedisposed plate removably held upon the rear end upright of the frame l and having a right-angled or bent portion equipped with a cushion or buffer 24, is adapted to reduce the concussion which would otherwise occur and arrest the return movement of the carriage as the spring 2l delivers its stress or pressure upon the latter.

A preferably tubular rod or mandrel 25 capable of reciprocating is held in an upper end tubular bracket 26 of the rear end upright of the frame 1; and into the forward end of said rod or mandrel may be screwed or held either a tubular corer 27, or a pin 28, as it may be desired to core fruit, as an apple or the like, or support a vegetable as a potato for treatment, as in slicing the same. A brace or rod 29 has one end hooked into an aperture in the top-plate of the knife-carriage 5 and its upper end provided with an upstanding eye-ended terminal adapted to allow the insertion through it of the eXtension of the corer 27, or of the pin 28, whichever may be desired for use, in connecting either of these latter to the mandrel 25, said rod or brace thus serving to eect connection between said mandrel, carrying said corer or pin, and the knifecarriage.

A push-off 80, consisting of a bent, edgewise-arranged plate, is removably held at its rear end laterally upon the bracket 26 of the rear end upright of the frame 1, with its bent or lateral forward end portion rounded out and adapted to provide for the passage therethrough of the corer 27 as the latter is connected to the mandrel 25 as will be readily understood.

.A preferably tri-bladed or winged holder 31 effective for stabbing and holding the fruit for treatment, is arranged at the opposite or forward end of the machine, the -same terminating one end of a shaft or spindle 32 suitably journaled in that end upright, which spindle or sha-ft is driven by a pinion 33 fixed thereon and meshing with the internal toothed wheel 4L as the latter is actuated as is obvious.

A guide-bar 34 is suitably fixed to, and offset laterally from the frame 1, oppositely to, and so as to allow of the engagement therewith of the eXtreme inner or lower end of the dog 16, said bar having in its underside, near the edge neXt to the dog and con- Y tiguous to its forward end, an upward curved cam groove 35 opposed to which is a guardplate 8G fixed to the underside of said guidebar. Also just forward of said cam-groove is a notch 37 indenting laterally said guidebar. Again, indenting said guide-bar laterally, along the same edge, at a point which will allow the escape of the point or extreme inner end of the dog when the knife-carriage has reached the end of its return movement, is a recess or slot 38, which, when desired, may be filled-in or closed by a set-screw held slide or closure 39 as when it may be desired to shorten or lengthen the travel or retum movement of the knife-carriage; in that event an additional recess or slot as at 40 being provided in said edge of said guide-bar for the escape of the point of said dog.

It will be noted that, when the knifecarriage 5 has moved, in its forward travel, so that the point of said doo' will ride up into the cam-groove 35 anc during such movement, the knife will move inward fo-llowing the act-ion of the arm 20, and thereby treating the butt of the apple around the stem-portion, said point of dog then passing out of said groove and accordingly downward and forward bringing the knife back to initial position. 'The point of said dog will finally escape upward out throigh the notch 87 to the upper side of the guidebar, when the action of the spring controlling the dog will have disengaged it (the dog) from the screw-shaft, thus allowing the sending of the knife-carriage back to its starting point for a like operation. l/Vhen the knife-carriage has moved to the eXtreme limit of its forward movement the corer, it will be noted, will have penetrated clear through the fruit thus decoring it, and that, when the carriage makes its return transit, the fruit thus pared and decored will be brought into forcible contact with the push-off, since the latter will stand just sufliciently in rear of the forward end of the corer to be thus acted upon and provide for automatically ejecting or pushing the fruit olf said corer.

Vhen it may be desired to treat or slice and peel potatoes, the various parts used in treating fruit as above noted are dismantled and the machine organized as disclosed by F ig. 8, the knife l1 with the lateral point 42 substituting t-he previously used paring knife and the slide 39 screwed into such position as to fill-in or close the slot or recess 38, as indicated.

It will be appreciated that this machine is simple in construct-ion, readily and advant-ageously operated and cheaply manufactured.

I claim- 1. A device as described, comprising a knife-'equipped carriage, a spring controlled dog carried by said carriage, a guide-bar in engagement with one end of said dog, a screw-shaft engaging said dog, said dog having its handle-member provided with an` arm engaging a cam-projection upon the knife stem, a spring for controlling the movement of the knife stem, said guide-bar being adapted to coperatie with said dog for effecting the aforesaid engagement between said arm and said cam-projection to cause said knife to perform a curving movement just before the knife-carriage reaches the limit of its forward movement.

2. In an apple paringimachine, the combination with a frame, of a screw shaft mounted thereon, a carriage mounted on the shaft, a spring controlled dog on the carriage, a guide bar adapted to engage the doo' for throwing it into engagement with the Screw shaft, a knife mounted on the carriage, and means for rotatingthe screw shaft whereby the carriage is moved and the knife caused to engage the fruit.

3. A device as described, comprising a knife-carriage having a spring-controlled dog provided with an arm effecting engagement with a cam-projection upon the knifestem, a Spring for controlling the movement of ythe knife stem, a screw-shaft for transmitt-ing movement through said dog to said carriage, a tripping guidebar for said dog, and a spring for controlling the return movement of said carriage, and means for actuating said shaft.

4. A device as described, comprising a knife-carriage equipped with a spring-controlled dog, a spring for controlling the return movement of said carriage, a screwshaft, means for actuating said shaft, a sliding mandrel, a push-olf fixed with relation to said mandrel, a corer carried by said mandrel, means effecting fixed connection between said carriage and said mandrel, a guide-bar being equipped with a camgroove for engagement with `the point of said dog and having a closure-controlled slot or recess for the escape of the point of said dog therethrough, said dog being provided with means for controlling the action of the knife carried by said carriage.

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