PINEAPPLE-GOREB IN A PINEAPPLE CORING AND SLICING MACHINE.

Specification of Letters Patent.

Patented June 8, 1915.

Original application filed October 12, 1914, Serial No. 866,330. Divided and this application filed February 18, 1915. Serial No. 9,024.

To all whom z't may concern:

Be it known that I, FRED W. VVOLF, a citizen of the United States, residing at Honolulu, island of Oahu, Territory of Hawaii, have invented a new and useful Pineapple- Gorer in a Pineapple Goring and Slicing Machine, of which the following is a specification.

This application is a division of my application filed October 12, 1914, Serial No. 866,330, for pineapple coring and slicing machine.

The object of the invention covered by the present application is theprovision of novel coring means and novel means for holding the pineapple during the coring operation and subsequentl Y to discharge it. I attain these and other objects of my invention as hereinafter more fully disclosed, by the mechanism illustrated in the accompanying drawings, in which I Figure l is a side elevation of my machine; Fig. 2 is a top plan of the machine; Fig. 3 is an enlarged detailed sectional view of the turret showing the means for'holding the pineapple during the coring; and Fig. 4 is a detail sectional View of the coring means on line 44 of Fig. 3; Fig. 5 is a detail of member 48.

Like characters of reference indicate like parts throughout the several views.

Referring to the accompanying drawings, mounted on a suitable supporting frame I provide a main driving shaft 2, operated by pulley 1 and clutch 3. Mounted on the main driving shaft 2 is a bevel gear 4 meshing with bevel gear 5 on an upright shaft 7, which is supported by bracket 6. Mounted on the upper end of the shaft 7 is a crank disk 8, to which is secured a pitman 9. The opposite end of the pitman 9 is connected to crosshead 10, the latter being slidable on guide rods 11, which are supported by castings 12 on the frame, as illustrated in Figs. 1 and 2. Crosshead 10 in turn operates coring tube 40. On main driving shaft 2 are keyed disks 13 and 14, between which is mounted a locking hub 15. Inserted in disks. 13 and 14 is a pin (not illustrated) which operates Geneva wheel 17, which is keyed on turret shaft 18. Mounted on turret shaft 18 is the turret 19, which, as illustrated, is composed of novel hooked, starpointed plates or disks 20, spaced apart one from the other by offset ribs 21. The series of disks 20 are held together by bolts 23 and hub members 22 which bolts 23 fasten together. The series of disks 20 revolve between two turret castings 25 which are mounted on the main framework of the machine. Suitable means (not illustrated) are provided to prevent hub members 22 from becoming too tight.

Rotatably mounted on top of the turret castings, as shown at 31 in Fig. 3 is a shaft 32 to which is attached a curved plate member 33. It has a pivotal or swinging movement when shaft 32 is partially rotated. To the end of shaft 32 is attached a cam lever 34, to the lower end of which is attached a spring (not illustrated), which in turnis fastened to the frame of the machine so as to hold the member 34 in tension against a cam 36 mounted on the main driving shaft 2. WVhile the fruit is being cored it is held in the pocket formed between the hooked star ends of the turret plates or disks 20 by plate 33. A stationary cover plate 37 is fastened to the turret castings 25 forward of the flap or cover plate 33.

Pineapple coring tube 40, carried by crosshead 10, is supported by castings 12. It is reciprocated by the crosshead to core the pineapples at intervals when the turret is stationary, intervening between its intermittent movements. An inner sleeve guard 41 encircling coring tube 40 is mounted between casting 12 and turret casting 25. Goring tube 40 has a sharpened mouth 42. For the reception of the mouth 42 of coring tube 40 I provide a coring knife guide 43. This member has an annular groove 44 which encircles a central core 45, over which the mouth of the coring tube 40 projects as it completes its coring stroke, thus preventing dulling of the sharpened mouth 42 and pushing the cored portion of the pineapple farther into the coring tube, and ultimately discharging successive cores from the opposite end of the coring tube. An outer sleeve guard 48 (shown with part broken away, in Figs. 1 and 2, only a small portion of the member being shown) projects from the end of the frame to protect the outer end of coring tube 40. This is shown in detail in Fig. 5.

In operation, the pineapples, which have previously been suitably prepared (pared and trimmed), are fed into the turret by suitable means such as chute A and received in the pocket, as at B in Fig. 4, between suc- V the turret revolves step by step, regulated by the Geneva wheel 17, until it reaches the coring position, indicated by C. lVhile the shaft 2 is making one revolution, the Geneva wheel 17 and the turret 19 are moved forward one step or pocket and then locked in a temporarily fixed position by locking hub 15 engaging with the curved surface of the Geneva Wheel 17 The crank diskS is so timed with the main driving shaft 2 that the coring tube is pushed through the fruit while the turret is locked or stationary, the fruit being held by plate 32. After the coring operation the next step or movement of the turret 19 brings the pineapple in contact with means for slicing the pineapple, set forth in my original application, iereinbefore referred to. The pineapples remain in a horizontal position throughout the coring and slicing operations.

What I claim is:

1. In a pineapple machine, the combination of an intermittently revoluble turret adapted to retain fruit in a stationary horizontal position during the coring operation,

a horizontally slidable coring tube to core Copies 01' this patent may be obtained for the fruit while in a stationary position, horizontally actuated reciprocating means driving the coring tube, and tubular protecting members within which the coring tube travels. V v

2. In a machine of the class described, the combination of a revoluble turret consisting of spaced plates having hooked, fruit-engaging star ends to retain the fruit in horizontal position, a pivotally mounted curved plate intermittently engaging over the fruit to retain it in a fixed position, a reciprocating coring tube positioned to core the'fruit While engaged by the aforesaid plate, and means for actuating the coring tube to core the fruit during the interval that it is in stationary position, substantially as set forth.

3. In a pineapple machine, a revoluble turret having a plurality of hooked star end portions to convey the fruit, adjustable 'means engageable over the fruit to retain it in a fixedposition relative to the portion of the turret in which it is disposed, and means for coring the fruit when thus retained.

In testimony whereof, I hereunto affix my signature in the presence of two witnesses.
