MACHINE IFOR PARING APPLIES.

.SPECIFICATION forming part of Letters Patent No. 319,332, dated inne 2, 1385.

Application tiled May 3, 1881i. (Model.)

To all whom it may concern:

Be it known that I, L. HERBERT SCOTT, of the city of Newark, in the county of Essex and State of New Jersey, have invented a new and useful Improvement in Machines for Paring Apples, of which the following is a specification.

`My invention relates more particularly to machines for paring apples, and by the same operation cutting out a cylindric core and forming or producing a spiral shaving or slice from the portion surrounding the core; but certain features of the invention are applicable to paring-machines which do not core or slice the apples, and, although machines of the Vclass to which my invention relates are most lcommonly known as apple-parois,77 they maybe used for paring other kinds of fruit.

The object of my invention is to increase the facility which machines of this kind afford for rapid work, as a few seconds of time saved in the paring of each apple is a matter of importance where the machines are in constant shown inFig. 3, showing them in a differentl Fig. 5 is a view of a blank from position. which I produce a coring and slicing knife,

vand Fig. 6 is a view similar to Fig. 3, but

showing only the paring-knife, its supports, and a portion of the frame.

Similar letters of reference designate corresponding parts in all the figures.

A designates the frame of the machine, which may be made of malleable or cast iron, and Iwhich comprises a clamp and screw, ,whereby the machine may be iirmly secured to a ta- The frame of the mable or other support.

thine, which ymay be of cast metal, comprises a base portion, A, end portions, A A, and a rib, A3. In the end portion A are bearings b,wherein is arranged to turn and slideaspiiidie, B, having at the inner end a fork, c, and at the outer end a hand-crank, d, for turning it. The apple or other fruit is to be iinpaled on the fork c.

The paring-knife c is similarto those here tofore in use. It is secured in a knife-holder, c, which is carried upon a piiitle or pivot, e?, projecting upward from the outer or free end of an arm, G, which is pivoted at e3, so as to be capable of swinging in a plane transverse tothe axis of the fork'spindle B. A spiral or other spring, e4, applied at the pivot c, tends to hold the arm O in the position .shown in Fig. 3, and the end of said arm then rests on top of the rib A3 on the base portion A o f the frame, as shown in Fig. 6, and forms a stop to prevent further upward movement of said arm.

The movement of the arm C on its pivot ci, and the turning of the knife-holder e' on its pintle e2, provide for reaching all parts of the apple by the paring-knife c.

The coring and slicing knife D is best shown in Figs. l and 3, and the blank from which it is formed is shown in Fig. 5. The knife is formed by cutting out a blank of the forni shown in Fig. 5 from sheet-steel. This blank has an aperture, f, of the size of the core to be cut, and a lip or projection, f", extending thereinto. The blank is slitted at :i: from the aperture f downward, and the two portions thus formed are set out of line-that is, one edge is set forward and sharpened to form a slicing-knife, ft, and the lip f is turned ontward at right angles to the face of the blank 'to form the coring-knife, also designated by the letter f v Y The coring and slicing knives are thus produced ata low cost, and are very effective. The knife D is secured to the end portion A2 of the frame. Y

E designates a feed-rack, which is mounted on centers or journals f/ inthe end portions A A2 of the frame, in such manner that it may be swung from a position shown in Fig. 3, in which the teethare presented approximately Vradially to the center of the fork-spindle B, to

IOO

a position shown in Fig. 4, in which its teeth are presented away from the machine.

'Io the end of the rack-bar E, which is adjacent to the knives, is pivoted alatch or catch, g', adapted to engage with a projection or abutment, g2, on the rib A3, as shown in Fig. 3, and by pressure on the upwardly-presented arm g* of this latch or catch it may be disengaged from the projection or abutment g2 and the rack E swung outward on its pivot g, as shown in Fig. 4. rIhe latch g is held in engagement with projection g2 by a spring, g3.

Upon the fork-spindle B is a disk or wheel, F,whereon is formed a cam, h, consisting of a section of a screwthread adapted to engage with the' teeth of the rack E.

At the end of the rack E -distant from the knives the rack is provided with a single tooth, z', isolated by a space, z", from the remaining teeth of the rack, and the purpose of which will be soon explained.

In order to detach the core from the fork c automatically, I arrange in a groove in or upon the spindle B a push-piece, j, which consists of a rod or piece of metal bent down at the outer end, so as to lie within or at the bottom of the fork c, and bent outward at the other end, so as to strike upon the bearing b of the frame when the spindle is pulled backward.

It is obvious that if the spindle were not held in some way against backward movement an apple could not be placed on the fork c, for the necessary pressure would force back the spindle, and the push-piecej would be thrown forward and prevent the impaling of the apple on the fork.

In order to operate the machine, the parts are brought to the position shown in Figs. l and 2, the rack-bar E being held in place by the catch or latch g engaging with the Xed abutment g2 on the frame. The cam or screwthread h is engaged with the isolated tooth t', which serves to hold the spindle against backward movement while an apple is placed on the fork c. Now, it is obvious t-hat after thus securing the apple on the fork the spindle must be moved ahead a short distance before the knives operate upon the apple. To move the spindle forward by turning it (the rack being continuous from the tooth i) would require two or three idle turns and eonsumean appreciable time, and it is to avoid this waste of time that I form the space t" between the isolated tooth t and the teeth of the rack proper, and thus enable the spindle to be slid ahead after the apple is on the fork until the apple comes to the knives. As the spindle is turned the cam 7L, by engaging with the teeth of the rack E, advances the spindle, and carries the apple past the paring-knife, and also subjects it to the action of the coring and slicingknife D, whereby a spiral slice or shaving is cnt oft', leaving a eylindric core on the fork. When the spindle B has advanced far enough to complete the operation of coring and slicing, the end h* of the spiral cam h comes against the upward projection g* pusher or push-piece j strikes the bearing b the core will be thrown off the fork. The spindle B is then pushed forward until the cam h is in line with the space i. The rack E is then swung into position and secured by the latch or catch g', and the operation is again repeated.

I am aware that it is not new to employ for feeding the spindle of an apple-paring machine longitudinally a fixed rack and a cam consisting of a section of a screw-thread engaging with said rack and Xed on the spindle, said cam having a gap or space, which permits the direct longitudinal movement of the spindle when the cam is turned, so that said gap or space coincides with the rack.

I am also aware that it is not new to employ in such a machine a fork-spindle which is incapable of longitudinal movement, on which the apple is placed, and- 'a sliding frame carrying the paring-knife and provided with a rack, with which :engages a worm on the spindle for the purpose of moving the rack. In such a machine the spindle has been sup'- ported in slotted bearings, so asv to permit of its being raised to free the worm from the rack, in order that the sliding frame maybe quickly returned after operation, and for the same purpose the rack has been pivoted at one end, to permit of a vertical swinging movement in order to free it from the worm.

I do not claim any of the features above described as of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is-

l.' The combination, with a lfork spindle provided with a disk, F, having upon it a screw-thread cam, of a rack, with which said cam engages for feeding the spindle along, and which is provided with an isolated tooth, with which said cam maybe engaged for holding the spindle while placing an apple upon the fork, substantially as and for the purpose herein described.

2. The combination, with the frame and its bearings b, of the spindle B, provided with the fork c, disk F, with its screw-thread cam 7L, the pusher j, and the rack E, having the isolated tooth i, all substantially as andy for the purpose herein described.
