FRUIT PARER AND CORING MACHINE.

SPEGFICATION forming part Of Letters Patent N0. 718,687, dated January 20, 1903. Application filed May 16. 1902. Serial No. 107,576. (No model.)

To @ZZ whom t may concern:

Be it known that I, LUCIEN I. YEOMANS, a citizen of the United States, residing at Walworth, in the county of Wayne and State of New York, have invented an Improvement in Fruit Parer and Ooring Machines, of which the following description, in connection with the accompanying drawings, is a specification, like characters on the drawings representing like parts.

This invention has for its object the production of a novel machine by which to rapidly pare and core fruit and remove the saine from the coring-blade.

The machine is devised also to automatically discharge the core from the fork.

The particular features in which this invention consists will be fully described in the specification and pointed out in the claims thereof.

Figure 1 in side elevation represents a machine embodying my present invention in one of the best forms now known to me. Fig. 12 is a detail referring to the clamping-hub holding the coring-blade. Fig. 1b is a'detail showing the core detached from the machine, said core being also represented in Figs. 1 and la. Fig. 2 is a plan view of the machine shown in Fig. 1. Fig. 3 is a sectional detail in the line fr, Fig. 2. Fig. 4 is also a partial sectional detail inthe line oo, Fig. 2. Fig. 5 is an under side View ofA the casting shown in Fig. 4 in section and the arm or lever to which the knife-carrier and knife are secured. Fig. 6 is a detail showing the stop-plate detached. Fig. 7 is a sectional detail of the core-discharging means. Fig. 8 is a section looking to the right of the dotted line ac3, Fig. 7. Fig. 9 is a section in the dotted line 004, Fig. 7.

The framework A of the machine is of suitable shape to sustain the working parts, to be described. The right-hand end of the machine-frame has a base part A', (shown best in Fig. 1,) it being adapted to set on a table, and the left-hand end A2 of the machine is extended forwardly from the base, leaving an overhanging part with a space below it in which the coring-blade and the paring-knife may be moved, said coring-blade and paringknife depending below the overhanging end of the frame.

The framework has suitable lugs A3, that receive and sustain a guide-rod A4, that is embraced by hubs A5of a carriage A6, having a foot A7, that rests upon and partially embraces a guide-rod A8, held in the base of the frame. This carriage sustains the turn-table, to be described, carrying the paring-knife and also the coring-blade, and said carriage and blade are moved to and fro during each par- 6o ing and coring operation, the turn-table carrying the paring-knife being partially rotated during such action and the coriug-blade being tipped that the cored fruit held upon the coring-blade may be discharged therefrom by a suitable doffer, to be described.

The outer or right-hand end of the carriage A6 is bored to receive loosely a stud B, with which is connected by suitable setscrews an H-shaped frame BX, represented as having 7o four bearing-points, that in the sliding movement of the carriage A6 contact with the lower edges of suitable guides, as C. The outer part A2 of the framework sustains two such guides, only one being shown in Figs. 1 and 75 2, each guide being acted upon by two of the bearing-points of the frame BX.

Each guide O is slotted at O2, and bolts C', extended through said slots, enable the position of the guide to be changed to provide for 8o wear between it and the carriage BX, and by extending the bolts C through slots C3in the part A2 of the framework the guides may be adjusted longitudinally to provide for the turning of the frame BX at any desired point in its outward throw. The guide O has connected with it by bolts ca depending dolfer O6, that stands in a plane at one side the plane of movement of the coring-blade B2.

The stud B has secured to it the part B of 9o the ooring-blade carrier, other parts of said carrier being designated as an arm B3, connected with the part B by a suitable bolt B4, and a splitcarrying-sleeve B6, connected with said arm by a bolt B5. The split carryingsleeve has a set-screw ax, (see Fig.1*,) that may be made to contract the split carrying-sleeve and clamp firmly the coring-blade bushing B7, said bushing being shaped to present a space, as shown in Fig. 1b, having longitudiroo nal shoulders 61. The rear end of the coringblade is inserted in space 60. The concaved inner side of the blade contacts with the convexed bottom 62 of the space, said bottom being in a circle of a lesser arc than the circle defining the rest of the body. The side edges of the blade contact with the shoulders 61 of the space 60.

In fitting the bushing for use the exterior thereof is made to correspond as nearly as possible with the circle occupied by the exteriorof the corng-blade, and one-half of the bushing at one side of a line longitudinal to the axis thereof is reduced and shaped to eX- actly iit the interior concaved side of the coring-blade, so that said blade whenever inserted in the clamping-hub and sustained by the bushing may be accurately held and positioned wherever desired.

The level-B of the coring-blade has an upwardly-extended lug b, that as the carriage A6 is moved to the left after the fruit has been pared meets the adjustable stud C5 just as the left-hand bearing-points of the frame BX arrive at the rounded ends 2O of the guides C and cause the eoring-blade to be tipped, the stud B turning in the end of the carriage A6, and during this operation the cored fruit held on the coring-blade striking the edge of the doffer C6 and ejected from the coringblade dropping into any suitable receptacle.

The carriage A6 has secured to it by suitable screwsE an arch E, (see Fig. 2,) the upper end of which (see Fig. et) receives a post E2, the post being retained in the arch by a suitable nut, as The post has a shoulder d4, that sustains a turn-table E4, provided at its lower end with a series of teeth d5, (represented as three in number,) the lower end of the turn-table being slotted at E5 to receive the rod E, having at its upper end a hook (see Fig. 4) to engage a projection a6 of the turn-table and suspend the rod E loosely. The rod EG has connected to its lower end in usual manner the knife-carrier 007x, containing the usual knife employed for paring the fruit. The lower end of one of the teeth a5 has inserted in it a screw bl, said screw being made to sustain a plate b2, provided with a series of notches, (represented in plan view in Fig. 6,) into any one of which the arm E6 may enter whenever the fruit of whatever size is removed from the fork, a spring b2, connected with said lever and with said tooth, acting to seat the arm EG in one of said notches when the fruit is off the fork, thus preventing the paring-knife from contacting with the fork.

vAs has been stated, the carriage A6 is moved to and fro-t'. e., it is moved to the right,view ing Fig. l, when the fruit is to be pared and to the left after the completion of the paring operation.

The part A2 of the frame has a slotted bracket G, to which is secured by suitable screws G2 a toothed plate G', that as the carriage A6 is moved to and fr0 engages the teeth a5 of the turn-table and rotates the carriage, causing the knife-carrier and paring-knife to travel about the circumference of the fruit from one to its other end.

Referring to Figs. 2 and 1, it will be seen that the post E2 occupies a position directly over the longitudinal axis of the fork-shaft HG, and consequently over the axis of rotation of the fruit, so that the cutting edge of the paring-blade is always presented at the same angle to the exterior surface of the apple, whatever its size or shape.

The framework sustains a shaft D7,that carries a beveled toothed gear D5, having secured to it a partial gear D4, and at a distance from said shaft said gear D5 has secured to it a segmental rack D7.

That the carriage may be moved as stated said carriage has connected with it by suitable bolts ct2 a rack D, that is engaged by a gear Dl, secured to a shaft D2, mounted in suitable bearings in the frame, said shaft having a pinion D3, that may be engaged either bya partial gear D4 or by the segmental series of teeth D7.

,To rotate the gear D5, I have mounted upon a stud at the end of the frame a toothed wheel Il', having at its inner side albevel-gear H2, that engages the bevel-teeth of the gear D5. Nut H holds the gear on the stud and, as herein shown, the gear H is illustrated as being driven by hand, and for this purpose it is provided with a handle H2. The peripheral teeth of the gear H' engage an intermediate gear H4, that in turn engages a gear H5 on the fork-shaft H6, thus rotating said fork, and with it the fruit which may be impaled thereon.

Then the gear D5 is rotated in the direction of the arrow, Fig. l, the partial gear D, in engagement with the pinion D2, will turn the shaft D2 in a direction to cause the gear D', engaging the teeth D of the carriage A, to draw the same to the right; but after the teeth of the partial gear D4 run out of mesh with the teeth of the pinion D3 then the segmental rack D7 engages the teeth of the pinion D3 and turns the shaft D2in the opposite direction, thus causing the gear D to slide the carriage to the left at a speed faster than its forward movement.

The fork-shaft H6 is split at its forward end, as represented in Figs. 7 and 9, and is bored longitudinally for a part of its length, the bore receiving a core-discharger c. The inner end of the core-discharger has a connected pin that is extended through slots e' of the shaft HG, said pin entering a suitable collar c2.

The fork GX is provided with a screw-thread, by which to attach the fork to the split end of the shaft H, and the fork has a longitudinal central hole through which the core-discharger e may be moved.

At the proper time the core-discharger is moved forwardly with relation to the shaft H6 and the fork GX by means of an actuating device e3, shown as a curved lever, pivoted at IOO IIO

e4 and havinga backwardly-extended arm e5, that is acted upon at proper times after the fruit has been removed from the fork by the coring-blade to discharge the core from the fork, the actuator e3 deriving its motion from a suitable projection at the foot of the carriage AG. Y

In the operation of the device let it be assu med that the knife-carrier occupies its farthest position to the left, Figs. l and 2, the position in which it is left after the action of the segmental rack D7 on the gear D3, and that the coring-blade is thrown up and is in the position occupied .by it when the pared fruit was discharged therefrom. In this condition the fruit to be pared-such, for instance, as an apple-is placed upon the fork GX in usual manner, and the fruit acting against the carrier or its blade pushes the carrier away from the longitudinal center of the shaft HG against the stress of the spring b3. Now turn the gear II and start the gear D5 in the direction of the arrow thereon, Fig. l,

and immediately the first tooth of the partial.

gear D4 will engage the teeth of the pinion D3 and will turn the shaft D2 in a direction to move the carriage A6 to the right. During this movement the coring-blade will come into its horizontal position andwill enter the fruit and the turn-table will be started and revolved in the direction of the arrow, Fig. 5, causing the paring-blade held by the spring b3 and contacting' with the inner end of the apple to travel about the apple from its inner toward its outer end, thus paring the apple, and at the same time the coring-blade passes through the apple and cuts out the core, leaving it held by the fork. During this movement of the coring-blade it is prevented from moving laterally or vertically or other than longitudinally forward by reason of its firm hold between the bushing and the split hub and by reason of the projections bx running squarely on the guide C. The turn-table is turned a half-revolution about the post E2.

As the paring-knife finishes the paring the coring-blade completes the cutting of the core, and at this time the carriage A6 reaches its extreme throw to the right and the last tooth to the left of the partial gear D4 retires from contact with the pinion D3, letting the first tooth of the rack D7 engage the said pinion and rotate the shaft D2 in the opposite direction, returning the carriage at a relatively greater speed than the speed at which it was rotated during the paring and coring operation. As the carriage retires to its starting position the coring-blade withdraws the cored apple from the fork,and as the lug b strikes the adjustable stud C the coring-blade is tilted, causing the apple held by the paring-blade to meet the doffer C6, thus discharging the apple from the paring-blade. As the carriage A6 nears the end of its stroke to the left a pin, cam, or lug upon the outer part of gear D5 strikes a projection attached to the arm E5 of the actuator e3 and moves said actuator, so that its upper split end embracing the shaft H6 acts against the collar e2 and slides the core-discharging device to the left, effecting the discharge of the core from the fork, leaving the parts at the completion of a cycle of operation in position to have another apple placed on the fork and the operation repeated.
