IVILLIAM IV. MCMILLAN, OF HURLETON, CALIFORNIA..

APPLE PARER, SLICER, AND CoRER.

SPECIFICATION forming part of'Letters Patent No. 334,130, dated January l2, 1886. Application filed December 29, 1884. Serial No. 151,490. (No model.)

T0 all whom t may concern/f Be it known that I, WILLIAM W MCMIL- LAN, of Hurleton, county of Butte, and State of California, have invented an Improvement in Apple Parers, Slicers, and Corers; and I hereby declare the following to be a full, clear, and exact description thereof.

My invention relates to a new and useful apple parer, slicer, and corer of that class in which a carriage carrying the knives for paring and slicing is advanced against and past a rotating apple, which is afterward removed, independently of its core, by aswinging arm, said core being also discharged; and my invention consists in the devices which I shall hereinafter describe, and specically point out in thel claims.

rIhe object of my invention is to provide a machine capable of doing more work in less Fig. 2 is a front elevation oi' one side of the machine. Fig. 3 is a view showing in detail the operation of the lever-rod It, slide S, and pawl-rod T. Fig. 4 is a View showing the treadle engagement with the beveled catches b of the strips B', and the contact of the short arm o with the pivotedlever W.

A is the frame or stand of the machine. At its front is a cross-bar, B, on which are secured iirmly two paring and slicing machines of the ordinary form, well known on the market, and illustrated in United States Patent No. 93,574, August l0, 1869. The two machines are placed in line and have corresponding parts, but are in a reversed position, as shown.

A description of one of the machines will answer for the other. It consists of a rigid frame, C, having astandard, c, in the top of which is journaled the apple-holding fork D, which is rotated by means of a pinion, d, on its stem, which engages with a driving-wheel, E, internally geared. A longitudinal screw, F, is driven by means of a pinion, f, meshing with the gear E. Upon alongitudinal track or slide-rod,'G, is mounted the carriage H, on which is secured the parer-knife h, which is adapted to have a movement on its pivot to conform itselfto the curvilinear surface of the apple by means of a cross-pin, h", by which its' shank is journaled in the carriage I-I, and a' spring, h2, by which it is held to its position.'

The carriage H also carries the Slicer-knife I, of the usual pattern, and a locking pawl or holder, J, `which is adapted to engage with a' longitudinal bar, j, on which the screw is mounted. The-carriage also has the stud K, which engages with the screw, and by means of which the said carriage, with its appurte-I nances, is caused to travel upon its slide-rod.

i The' movements of said carriage are therefore` a longitudinal one, and also one through an' arc of a circle, which takes place when the holder is thrown back from its engagement at the inner limit of its stroke, by reason of the end of the holder coming in contact with an' inclined lug, j, on the back of the track j.

The operation of the device as far as de` 'scribed' is well known, the results being theI paring and slicing of the rotating apple.

It will be observed that the two machines' thus described are seated in a reverse direction-that is to say, their driving-wheels are adjacent.

These are'connected by means of a pulley, L. whereby the two are enabled to lact simultaneously, as I shall hereinafter del scribe.

It is usual, where a single machine is used,

ithat when the parer and slicer are thrown from,

their engagement at the completion of their work to move them back to the beginning of their stroke'by hand; but I intend in this com.- plete machine to cause this movement to beV effected by means of such a connection between `the two carriages as that when one is eoming'up' .to its work it shall cause the other to move` lback to the beginning of its stroke; and for4 this purpose I have thev rod M, the ends of'.

which are bent and have loops in, by which they are fitted, and are adapted to travel on. the slide-rods, on which the carriages H areY mounted. This rod M acts as a strut-connection'. between the two carriages, whereby the move-4 ment of the carriage which is coming up to itsv1 work transmits movement to the carriage", which is thrown out of its engagement, whereby said latter carriage is moved back to thel -Ico beginning of its stroke. It is also usual, in the is a shaft, O, carrying two small pulleys, o;

Attached to these pulleys and wound in opposite directions are straps P, which extend down to and are connected, respectively, with This strap-connection is of such.

the treadles. a character that the downward movement of one of the treadles rotates the shaft O in one direction, while the downward movement of the other treadle rotates it in the other direction, and in each direction of rotation one strap is unwound from its pulley, while the other strap is wound thereon. The center of shaft O has a large pulley, Q, from which an endless belt, q, extends to the pulley L, which connects the driving-wheels of the two machines in front. The respective dimensions ofthe pulleys o and Q and the pulley L between the driving-wheels are of such a nature that by a single downward stroke of the treadle the driving-wheels are rotated a sufficient number of revolutions to effect a complete stroke of the carriage.

Pivoted upon the outer ends of each sliderod G is a lever-rod.'R, one arm of which'is bent and lies for a short distance parallel with the slider-ods, and the other arm behind its pivot-point is connected by a spring, r, with a vertical moving slide, S, seated and guided in the frame A, and which is influenced to remain to its position by springs s. Upon the slides S are beveled catches s,`with which the tops of pawl-rods T engage. These pawl-rods have their lower endsl connected with the treadles and pass through suitable guides on the frame. When a treadle is raised, the upper end of its pawl-rod T rises above the catch s; but when the treadle is pressed down the pawl-rod engages with the catch s', pulling down the slide S, and thus through the spring r oscillates or throws up the lever-rod R.'

This rod, acting against a small lugor heel, w, extending from the carriage H, swings said carriage forward, so that its holder J falls to its engagement. This takes place at the beginning of the stroke, and fimmediately preceding the propulsion of said carriage to its work. There is one of these devices operating upon each side, and being dependent upon the treadles, their operation' is alternate, whereby each of the carriages H at the proper time is thrown to its engagement.

In addition to the slicing and paring of the apple I propose to remove the pared and sliced apple and force it upon a receiver, from which it is discharged into a suitable receptacle, and to follow up such a disposition of the apple bythe complete removal and discharge of its core. The following is the mechanism by which these results are effected: The frame A is provided witha hood, A', in which are pivoted the shafts U. On the ends of these shafts are secured the arms V V. The arm V is in advance of the arm V, and the lower ends of both arms are forked or grooved to enable them to straddle the pared and sliced apple and the core, respectively. In addition to these arms is a short arm, v, which operates against a pivoted lever or arm, W, the lower end of which has a pin, w, at right angles, and which acts as a receiver for the pared and sliced apple. The upper ends of the arms W are infiuenced to throw their lower ends down by means of springs w', and spring-catches X hold said arms in an elevated position when not in use. The arms V V have an oscillating movement imparted to them by the lfol` lowing means: Each set of arms is operated by the opposite treadle; and to accomplish tnis I have the bell-crank or elbowleverslY, pivoted at their angles upon the shafts U, and each connected by a'bar or strap, y, with a crank, Z, firmly fixed on the opposing shaft. The bell-crank levers have connected with their other arms the vertical strips B', the lower ends of which pass down through suitable grooves in the base of the frame,whereby they are guided. On their lower ends are beveled catches b', with which the treadles are adapted to engage, and which are thrown from their engagement by means of guide-strips c in their grooves. The upper ends of the strips B are connected by rods C with springs D on the top of the hood, and which serve to return the rods B to their position.

The full operation of the device is as follows: When at a state of rest, the knife-carriage of one of the machines is at the limit of its inner stroke (having completed its work) and is thrown backward out of engagement with its operating-screw, its heel resting on the cross-bar B, while the other knife'carriage is at the beginning of its stroke, and is also thrown back at an angle, its heel resting upon the bent leverrod It. A fresh apple is now placed upon the holdingfork of the machine to which the latter knife-carriage belongs, while the pared and sliced apple still remains on the fork of the iirst machine. The raised treadle is now pressed down. The iirst effect of this pressure is, through the pawl-rod T, slide S, and the bent lever-rod R, to throw the knife-carriage into engagement with its screw, and the next effect, through the straps P, pulleys o, Q, and L, and belt Q, is to rapidly rotate the screw, whereby the knife-carriage is advanced to its work, while by reason of the strut-connection M between the two carriages the carriage of the other machine is forced over to the beginning of its stroke. When the treadle reaches a point at its stroke 'where it comes into engagement with the catch b on the foot of the strip B', it presses down said strip, which, through the bell --crank lever Y, the connecting-strap y, and crank Z, communicates an oscillating IOO IIO

movement to the opposite shaft, U, whereby the arms V V of the opposite machine are made to describe their arc. In this movement the arm V in advance cornes down upon and embraces the pared apple which still remains upon the machine and forces said apple off the retaining-fork upon the receiving-pin w of the arm W. The continued movement then causes the short arm c to force said arm W upward, carrying the receiving-pin with its apple upward away from the machine until the upper end of the arm W is engaged by the catch X and is held. At the same time the rear arm,V, comes down upon and straddles the core and forces it off, when the operation of one treadle is complete. By this time the other treadle is raised and is pressed down for a repetition ofthe operation on the other machine. Before each stroke the receiver-arm W is released from catch X, when it moves downto position.

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