To oll whom it ma concern: 7

Be it known t at 1, JOHN W. PEAsn, a citizen of the United States, and resident of Rochester, in the county of Monroe and State of New York, have invented certain new and useful improvements in Fruit- Handling Machines, of which the following is aspeciiication.

This invention relates to machines by which apples or other fruit are automati cally presented or fed to the tork or fruitholding device of a machine for paring and coring, or otherwise treating the fruit, and particularly to feeding machines of the ty e in which the fruit is automatically broug t to, and presented in, a position in which the core-axis of the fruit has a definite position with relation to such ilork or fruit-holding device.

provide a fruit-handling or teeding'machine of the type in question with novel and eta fective means for holding the fruitatter its position has been automatically determined and until the operation by which the fruit is transferred to the paring-machine, or

other machine for operating on the fruit. A second object of the invention is to proride the fruit-handling machine with novel and effective mechanism for so transferring the fruit and for impal'ing it upon a fork,

or equivalent device, said means being particularly adapted to hold the fruit securely againstoaccidentai alteration in the predetermined position of its core-axis, and to at; tain this result without injury to the suriace of the fruit. I

{)ther objects of the invention, and the features of construction by which they are attained, will be referred to hereinafter, and the invention consists in the iiruit-handling machine hereinafter described, as it

fined in the succeeding claims, 7

The invention is particularly adapted for embodiment ina machine operating upon the principle disclosed in United States Let ters Patent Nos. 980,371 and 980,462, granted January 3, 1911, to John A.,Warnor, that is to a machine in which the apple 7 or other ltruit is brought automa'ticall to a One object of the present invention is to,

definite position by floating the fruit in vwater or other liquid, and accordingly the pres ent invention is illustrated as embodied in a machine operating upon this principle, although it will he understood that certain teatiires or" the invention are equally adapted for use in machines in which the fruit is p0- sitioned in other ways or by other means.

' in a previous application filed by me April 5, 1911., Serial No. 819,195, I have disclosed a limit-handling machine, operating upon the. flotation principle, in which the fruit is carried by a series of fruit-holders mounted upon endless chains, thafruit being first fed into the holders, then immersed in a tmk of water to cause it to be automatically positioned in the holders, and

' the holders being'then brought to a position where the fruit may be transferred to the fork of a paring-machine. The present machine operates on the general principle thus disclosed, and the invention consists particularly in the construction of the fruitholders and the manner in which they grip the fruit after ithas been automatically positioned therein, and also in the mechanism by which 'the'fruit is transferred from the holders to the fork of the paring-machine. its in the machine disclosed in my said apliczition, the fruit is'fed one by one to the ruit-holders by ineans 0t feeding mechanism which constitutes no part of the present invention. A suitable mechanism for this purpose is shown in Figs. 1 and 2. The fruit is supplied through a spout 20 connected with a suitable hopper (not shown), and from this spout it is raised by means of a series of receptacles 21, each consisting of several spaced fingers, as shown in Fig. 2. The receptacles 21 are mounted on endless sprocket-chains 22 which pass over upper and lower sprockets 23 and 24, respectively. The sprockets 24 are fixed to a shaft 25 which is connected, by a chain 26, with a sprocket on a shaft 27 journaled in the frame 35 of the machine, and the feedingmechanism is thus actuated through the intermittent movements of the shaft 27, which are produced by mechanism hereinafter described. Each receptacle discharges the fruit held therein, in turn, into a chute 28, through which the fruit is discharged by gravity into one of the holders, indicated generally by the reference-number 29, which at the time is momentarily held stationary beneath the chute. The fruit-holders 29 are mounted in series on r a pair of endless sprocket-chains 31., At the right-hand end of the machine these chains pass over two sprocket-wheels 32 which are fixed to the shaft 27. At the left-hand end of the machine the chains pass over sprocket-wheels 33. The wheels 33 are journaled independently upon studs 34 fixed in the frame 35 of the machine, thus producing a clear space between the wheels in which the fruittransferring mechanism operates.

A tank 36, holding the water in which the fruit is automatically positioned, is mounted at the upper portion of the frame of the machine, so that several of the fruit-holders are at all times within the tank. To bring,"

the holders successively into, through and out of this tank, intermittent partial rotations are imparted to the shaft 27 and the sprocket-wheels 32 thereon. To thisend a cam-shaft 37 is journaled in the frame of the machine, and this shaft is connected, by gears 38 and 39., with a shaft 41 which may be connected'with an suitable source of power. The cam-sha t rotates constantly, audit is provided with a cam-disk 43 engaging a roller 44 on a cam-lever45, which is pivoted upon the frame of the machine. Th1s cam-lever is provided with a gear-segment 46 which meshes with a gear-segment 47 loosely pivoted upon the shaft 27. The segment 47 carries a spring-pressed pawl 48 whlch engages a ratchet-wheel 49 fixed to one of the sprocket-wheels 32. The camdisk 43 imparts intermittent oscillating movements tdrthe gear-segments, thus causing the pawl periodically to impart a partial rotation to the ratchet-wheel and the sprocket-wheels 32, the angular movement thus produced being equivalent'to the linear distance between two successive fruit-holders. The return movement of the ratchetmechanism is producedby a spring 40 conis idle as regards the sprocket-wheels and chains, owing to the idle movement of the pawl 48 over the ratchet-wheel.

A valuable feature of the present invention resides in an arrangement by which immersion of the chains 31 in the liquid contained in the tank is avoided. To this end the fruit-holders are arranged as shown in Figs. 3 to 6. The chains are located at the sides of the tank, and are provided, at suitable intervals, with yoke-shaped members 51 which extend upwardly and downwardly so as to bridge the sides of the tank. These members thus support the operative parts of the fruit-holders within the tank. At their inner extremities the yoke-shaped members 51'of each holderare integral with a fiat ring ,or base-member 52, which supports themovable members of the holder. A series of studs 53 project upwardly from the base-ring, and on these studs are pivoted a series of arms 54 having, at their inner rection will cause the corresponding simultaneous movement of all the blade-arms and the blades carried thereby, whereby the blades aremoved simultaneously toward or from the center of the cup. The ring '57 is provided with. two downwardly-projecting pins 61 to which tension-springs 62 are fixed, the opposite ends of the springs being fixed to pins 63 projecting downwardly from the base-ring 52. These springs tend constantly to rotate the ring 57 in a direction to move the blades 55 to closed position, as in Fig. 3, and this arrangement affords provision for yieldingly gripping a fruit in the holder.

The mechanism just described acts to hold the fruit in definite position in the holder while the fruit is being transferred from the tank to the fork of the paring-machine.

While the fruit is being automatically posi t-ioned by flotation, however, it is necessarythat it be free to turn within the holder. Accordingly, means are provided for holding the blades 55 in open position, as in Fig. 4, during this latter operation, The, ring 57 is provided with'two cam-rollers 64 on studs projecting downwardly from the ring, and in the bottom of the trough a double-faced cam 65 is fixed. This cam ex- 7 tends substantially throughout the length of the trough, from a point beneath the chute ,28. Accordingly, when the fruit-holder reaches this point the beveled end of the cam engages the rollers 64 and forces them in a direction to move the holder to. open position, and in this position the holder is maintained until it reaches the left-hand end of the tank. The sprocket-chains 31 pass beneath rollers 66 by which'the chains and the holders are depressed to cause the holders' to enter the tank after receiving the fruit, and the chains pass under similar rollers 67 near the lefthand end of the tank and thence upwardly over the sprocketwheeis 33, thus causing the holders to rise out of the tank. The cam 65 terminates ad- 15 jacent the rollers 67, so that just before each holder begins to leave the tank the blades 55 are allowed to close and grip the fruitin the position to which it has been automatically brought by flotation.

.By the use of a considerable number of vertical blades I produce a holder which adapts itself to fruit of a wide range of sizes, while at the same time the space be tween any two successive blades is not suiticient, when the holder is wide open, to permit the smallest fruit to escape .or become lodged between the blades. The simultaneous inward movcmentof the blades also provides for the automatic adjustment of the fruit to a position in which its core-axis is centrally located with respect to the holder, so that thefruit is properly positioned in this respect when presented to the fork of the paring-machine. The parallel 5 vertical blades have the further advantage that when'the fruit is forced out. of the holder in an axial, direction they diminish the tendency of the fruit to turn in consequence of the frictional engagement be- 0 tween the fruit and the blades.

In Fig. 1 the fork 68 of the paringmachine is illustrated in the position which it occupies with' relation to the fruit-handlmgmachme, this position being such that 5 when the fork is reached by one of the fruitholders the axis of the fruit held therein is horizontal and in .alinement with the axis of the fork.

A valuable feature of the invention re- 0 sides in the means by which the fruit is application above referred to this operation is performed by a bodily movement of the holder toward the fork, so that the fruit isimpaled before its removal from the holder.

In the present machine, however; the'holder remains stationary andthe fruit is forced therefrom.

';To hold the fruit-securelywith its axis in.

the proper horizontalposition during the transferring operationI employ a slender as pointed device which is hereinafter referred to as the spear," and designatedin the drawings by the reference-number 71. This spear is fixedin a slide 72 which is inclosed within a hollow plunger 73. The plunger moves horizontally'in bearings 74 on-the frame of the machine. A pin 75 fixed in the slide 72 projects laterally through a slot 7 6 in the plunger, the forward bearing 74 be-- ing recessed, as shown in Fig. 9, to clear the pin. A spring 77, inclosed within the plunger, engages the slide 72 at oneend, and its other end is seated. against a block 78 fixed. in the plunger. The slide and the spear thus normally participate in the movements of the plunger, so that when the plunger is advanced the spear passes through the bot tom of the fruit-holder and enters the. fruit at or adjacent to its core-axis, thus impaling the fruit and effectually preventing it from turning out of, proper position during subsequent operations. The mechanism by which the plunger and the spear are actuated comprises a plate 79 fixed on the cam-shaft 37 and having a campath 80 engaged by a roller on a cam-lever 81. The lever 81 is pivoted on a stud 82 fixed in the frame of the machine, and it has an upper forked extremity 83 coiipcrating with a pin 84. This'pin moves in a slot 85 in the plunger, and is fixed in a slide 86 inclosed within the plunger. A compressionspring 87, between this slide and the block 78, causes the plunger to participate normally in the movements imparted to the pin and the slide by the cam-mechanism. As a further provision to this end the slide is providedwith a lug 88, which projects upwardly through a slot in the plunger and is normally engaged by a spring-pressed detent .89 pivoted upon the plunger. Dur ing the first partof the operative movement of the cam-mechanism the plunger is moved positively forward, carrying the spear with it andthus impaling the fruit. Through the continued movement of the plunger its forward end then engages the fruit, and acts as an abutment by which the fruit is forced out of the holder and into engagement with the fork 68, the fruit being thus impaled upon the fork. As it is necessary that the plunger move sufficiently to completely impale the smallest apples, while at the same time its movement must be arrested at an earlier point where a larger fruit is being ther movement of the slide 86 merely compressing the spring 87. Upon the return movement of the parts the detent again engages the lug 88, however, thus locking the 5 parts'so that the first part of their next forward movement is positive. Since considerable force may be necessary to for ce the spear into the fruit, particularly when its. point happens to engage a stem or other unyielding part, I provide a positive abutment which is engaged by the fruit while the spear is entering the fruit. This abutment is in the form .of a plate 91, integral'with anv arm 92 which is' carried by a 1 shortrock-shaft 93. The rock-shaft is journaled in the frame of the machine between the sprocket-wheels 33. A gear '94 is fixed to the rock-shaft and meshes with a rack 95. V This rack is formed ona horizontal sliderod which slides in bearings on' the frame of the machine, and carries, at its righthand end, acam-roll 96. A cam 97 on the .shaft 37 moves the cam-roll and the sliderod in one direction, while a spring 98, connecting the slide-rod and the frame of the machine, moves it in the opposite direction. The cam is so formed that as one of the fruit-holders. attains a position of presentation, as in Fig. 7, the abutment 91 is swung forwardly and upwardly, between the sprocket-chains, into the position of Fig. 8, where its flat vertical surface may' be engaged by the end of the fruit. In order that-the abutment may bein engagement with the fruit, whatever the size of the latter, at the moment when the fruit is engaged bythe' spear, provision is made for a 'short rearward movement of the abutment in its operative position. To this end the 4 arm 92 is provided, as shown in- Fig.'10,- :with an opening110 inclosing anarm 111 projecting upwardly from the rock shaft 93. A spring 112, mounted on the arm, engages the rock-shaft and normally Holds the parts in the position shown, but when; the abutmenthas been raised to operative position the arm engages the bottom of the fruit-holder, as in F ig. 8, thus arresting its swinging ,movement, and the continued movement of the rock-shaft thentan'ses the arm 11-1 to move the arm 92 and the abutment 91 rearwardly, against the opposition of the spring 112, so that asthe'spea'r engages, and enters the fruit any horizontal movement of the-fruit in the holder is limited by this abutment'until thespear has fully entered the fruit. The abutment is then quickly released and swings backwardly to the position of Fig.7, where it does not interfere with the subsequent move ment of. the chains and the fruit-holders.

Owing to the variable movements of the plunger itis necessary that the movemen of the spear be, to' some extent, independent of those of the plunger. Accordingly, the

in the tank 107, and will 'carry thew-ater spear is mounted, as previously described, in

the slide 7 2, pressed forwardly by the spring 77. The forward movement of the spear is positively arrested when it reaches the position shown in Fig. 12, so that the point of the spear may not engage the base of the fork or other parts of the paring-machine. To this end a stop-arm 101 is located in position to engage the pin when the spear attains the forward limit of its movement, thus arresting the movement of the slide 72 while permitting the plunger to continue its forward movement if necessary. This stop-arm is formed upon a slide-rod 102 which has movements imparted to it for a purpose which will now be described.

After the fruit has been impaled upon the fork 68 the spear must be withdrawn from the fruit, and provision is made whereby the spear is, partially withdrawn 'and loosened from the fruit, while the fruit is still held upon the fork by'the' plunger, thus insuring against the accidental withd'raw'al of the fruit from the fork at this time. To thisend the slide-rod 102is provided with a roll 104 engaging a cam-path 105 formed in the cam-disk 79. This ,campath has a dip 106 so located that before the retreating movement of the plunger begins a shortbackward movement of the slide-rod and the stop-arm 101 occurs. By

this movement the slide 72 and the spear-- are retracted, thus loosening the spear from the fruit. The plunger then returns, carrying the slide 72 with it, and the stop-arm moves forwardly again to the normal posi-. tion shown in the drawings.

1 At the bottom of the machine atank 107 is provided, to receive the water dripping from the operative parts of the machine, and also to retain a supply of water from which the tank 36 may be replenished.- In order that this latter operation may be performed automatically each fruit-holder is provided with .a small .cylindrical receptacle 108, whichv is mounted on one of the yokes 51 and arranged at suchan inclination. thatit willbe filled witlrwater so received upwardly at the right-hand end of the machine, and discharge it into the might-hand end of the tank 36 as each fruit holder is brought: to position ,below the chute 28. i i

The-op'eration of the machine as a whole is as follows: As each fruit-holder reaches a position beneath the chute 28, it is thrown open by the action of a cam 65 located directlyfbeneath the, chute and adapted to engage the rollers'64 on the fruit-holder.

Here ,the fruit holder dwells for a moment while the fruit is discharged from one of the receptacles 21v into the chute, through "which it rolls into the fruit-holder. At the.

'ne'xt intermittent movement of the conveyer130 the fruit-holder, with the fruit, is carried into the water in the tank, and the fruitholder is momentarily closed upon the fruit by disengagement from the cam 65. During the next three successive forwartL movements of the conveyor and the intermediate dwells, the fruit is immersed in the water,

'whilethe fruit-holder is held open, and the advancing movements bring the fruit-holder into the position of presentation with respect to the fork 68 of the paring-machine, the axis of the fruit-holder and the coreaxis of the fruit being in horizontal alinement, with the fork. The abutment 91, now swings into position in frontof the fruit, while the spear 71 advances from the rear and im'pales the fruit. The abutment then retreats from the fruit and the plunger advances and forces the fruit. in the direction movements of the conveyor.
