APPLE PARER, CORER, AND SLICER.

SPECIFICATION forming part of Letters Iatent No. 288,956, dated November 20, 1883.

Application filed March 26, 1883. (Modehl To all whom it 717,601] concern:

Be it known that we, CHARLES S. Sector, of

Cadiz, in the county of Harrison and State of Ohio, and ROBERT P. SCOTT, of Baltimore city,

Maryland, have invented certain new and useful Improvements in Apple Parers, Corers, and Slicers; and we dohereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention relates to that class of appleparers which pare, core, and slice the apple in one operation.

1 1 The object of our invention is to produce a machine that will pare, core, and slice in a more expeditious and superior manner than usual with machines of its class, and also to be able, by simple adjustments, to only pare and core the apple, or simply pare the same, and accomplish these results by the most simple mechanism and convenient motions of the handsof the operator.

The invention consists, largely, in the mechanism for obtaining the desired motion of the slicing-knife, and also in the construction of the fork for holding the apple.

In the drawings, Figure 1 is a counter plan or under view. Fig. 2 is a front elevation. 0 Fig. 3 is a plan view. Fig. 4 is a detached view of connectingwheel G. Fig. 5 is a detached viewof coring and slicing knife K I. Fig. 6 is a view of connecting-worm E.

The peculiar style of parer to which our improveinents are attached is the common form of turn-table machine-that is, in so far as the relative motions of the driving-wheel, tablewheel, and fork are concerned. Instead of the usual pinion connecting the drivi ng-wheel shaft 40 with table-wheel, we substitute a worm. we have first a frame, A, Figs. 1, 2, and 3, which is attached to a table or board by means of lugs a a a, Figs. 1, 3. The lugs a a, are above and a is beneath the table. a is provided with 5 a clamp-screw. A driving-wheel, B, Figs. 1,

2, 3, is provided with a shaft, 1), having bearings in frame A, and by means of worm E, Figs. 1,2, 3, 6, turns the table-wheel F. The latter carries the usual paring-knife, L, both taking direction of the arrow on table-wheel F. The paring knife L drops toward the fork D at the outer or left end-that is, the apple is pared, commencin g at the blossom, and not at the stem, as most common. Asyou look at Fig.2, theknife L is held against the apple by a spring during the lower half of its annular course. It then throws outward and passesunder the shaft 0, Fig. 1, being held away from the apple during the remaining half-revolution.

The above motion of the paring-knife is so similar to other machines that it requires no further attention.

The table-wheel F revolves about a center screw or, pin, and is provided with a series of teeth, f, on its face, into which the worm E works. There is also a cam, f, which is apparently a continuation of a wide cylindrical surface extending at right angles from the face 7 of table-wheel F. The cam f and the three distinct series of teeth, f f f all projecting from cylindrical surface, operate the coring and slicing knife in connection with other parts, as follows: The teeth f f f 3 all work into a series of teeth on the face of wheel G. (Shown in Fig. a, on the anterior face of middle drawing by g.) The teeth f, Fig. 3, by their length and gradual slant, cause the toothed wheel G to revolve slowly. The short teeth f 2 cause a more rapid motion, and the one long straight tooth, f", causes a stationary position.

Now, it is desired that the slicing-knife I K should advance slowly from left to right against the apple, coring and slicing the same, and then that it should reverse its motion and return more rapidly to its original position and remain at the outer or left end, when it is tilted backward. To explain how this is accomplished, observe the middle drawing, Fig. 4, and notice the action of the teethf f 2 f as you would see them operate upon the series 9 on the face of toothed wheel G. The series f are intended to work below the line at y, Fig. 4, and the series f above said line, and the long tooth f 3 runs directly across the center of toothed wheel G. It is therefore evident that motion of wheel G will be as desired. The teeth 9, carried from right to left above the center, will carry the upper periphery of toothed wheel G from right to left, while the series f, running below the center, will carry the series 9 in a contrarydirection', and hence reverse the motion of wheel G. It is also evident that thelong tooth 1, running across the center, will hold wheel G stationary. Now,the tcethf,beinglonger and more sloping,

will cause wheel. G to revolve more slowly than the abrupt series f. The motions being understood, the corresponding action of the rack h and carriage H is apparent, as the wheel G 5 gears directly into the rack hby means of the second series of teeth, on the other face of wheel G. The carriage H slides upon a rod, M, Fig. 2. An arm, h, projecting, comes into contact with the cam f* and causesthe carriage H to' tilt back, thereby giving room at the end of the fork D to impale another apple. The portion of Wheel G shown as cut away, Fig. 1, is to allow the rack h to pass out, and,

if desired, can be thrown entirely out of gear.

A small spring, 6, pushes on the carriage, but does not prevent it being thrown entirely out of connection, if it is desired to only pare the apple. The carriage H has an arm, to which a coring device or corer and slicer, I K, is attached. The knifeI K is of peculiar construction, no single feature of which is entirely new; yet the combination is new and produces superior results.

The coring and slicing knife I K is composed of two elementsnamely, a blade, I, and a full circular ring, K. The former does the slicing and the latter cuts out the core. The ring is sharpened on its advancing edge, or may be provided with saw-teeth. The edge of the blade which performs the slicing part does not approach the ring in a line normal to the circumference thereof, but at an angle thereto. The blade I may be straight for its entire length; but it is preferred to har e it about straight until it comes nearly up to the ring, and then either curve or make a sharp angle toward the ring. Such a blade is common in knives not having the solid ring, and the said ring, with its advancing edge sharpened, is the subject of another application of one of the inventors. The fork D, Figs. 1, 2, 3, is rotated in the ordinary way by means of a pinion gear,- ing into wheel B. Said fork consists of two tines, d d, a knife, (1 between them, and stops d, which keep the apple from being pushed on too far. WVhen the apple has been cored and removed and the core left on the fork, we push the core out at the side from between the tines. If desired, the core can be pushed back against the knife and split in two. A coredoffer could easily be operated by the carriage H, but it is not thought necessary.

The especial style of knife L for paring is not necessarily a part of this invention, as a 5 5 paring-knife could be attached to the carriage H in advance of the knife I K. In this case the forward motion of the paring-knife would be somewhat similar in its action-on the ap-. ple to some machines in which a fork or car- 60 riage is operated by a screw.

The operation of the machine is substantially as'follows: The corer and slicer knife I K and parer-knife L, Fig. 2, both stand at the left end of their course, the knife L away 6 5 from the'fork D. An apple is now impaled on fork D and driver B revolved, when mo tion is transmitted to table-wheel F and knife L drops against apple and commences to pare. Almost simultaneously the cam f 4 passes from under arm h, when the carriage drops into position and the knife I K advances upon and through the apple, cutting out a cylindrical core and slicing the apple in a continuous spiral of the now common form. When the operation is so far completed, the knife L throws back and passes under the fork-shaft c, Fig. 1. At this instant the motion of the carriage H is reversed and the apple is carried off the core. The operation is complete when the carriage H has returned to its origi- 8o nal position and been tilted back by means of the cam f 4 coming into contact with the arm h. The core is removed as suggested in the description of fork D.

What we claim is 8 5 1. The combination, in an apple-parer, of the table-Wheel F and toothed wheel G, the former having a series of teeth or projections, f, j, and on its cylindrical surface, arranged, as described, to communicate motion to the toothed wheel G in both directions, and to retard or accelerate said motion, said toothed wheel Gr operating a reciprocating knife-carriage, substantially as described.

2. In an apple-parer, tlie table-wheel F, having a cam, f*, on its upper side, operating an arm, h, of a reciprocating knife-carriage, H, thereby tilting the knife I K, for the purpose of making room to place an apple on the fork, substantially as described.

3. The combination, in an apple-parer, of the three elements-namely, table-wheel F, connecting-wheel G, and knife-carriage H, said table-wheel F carrying a paring-knife, L, carriage H carrying a coring and slicing knife, I K, and connected with wheel G by means of a rack, h, the whole operating in such a manner as to impart a positive motion in either direction to the said carriage H without the use of springs, substantially as described.

4. The fork D of an apple-parer, provided with a knife, (1, between the tines, for splitting the core, substantially as described.

5. The combination, in an apple-parer fork, of a'shaft, 0, two tines, (l d, with a knife, d, between them, and stops c d for preventing the apple from being pushed on too far, substantially as described.

6. The combination, in an apple-parer, of a frame, A, shafts b a, worm E, table-wheel F, fork D, paring-knife L, connecting-wheel G, rack and carriage h H, rod M, and knife I K, working together for the purpose, and substantially as described.

In testimony whereof we aflix our signatures in presence of witnesses.
