SLICING-MACHINE.

Specification of Letters Patent.

Patented Aug. 3, 1909.

Application filed. May 29, 1906. Serial Nb. 319,326.

To all whom it may concern:

.Be it known that I, LOUIS E. citizen of the United States, residing at Honolulu, county of Oahu, Territory of Hawaii, have invented a new and useful SlicingrMachine, of which the following is a specification.

My invention relates to improvements in machines for slicing fruit and the like, particularly ineapples, in which the fruit is being forced against a plurality of stationary knives.

The object of my improvements is to roduce a machine of this character which is automatic, ra )id and efficient in operation. I accomplish these objects by the mechanism illustrated in the accompanying drawing, in which Figure 1 is a side elevation of the machine; Fig. 2 is a plan view thereof with the blades removed; and Fig. 3 is an isometric view of a cross-bar.

Similar characters ARNOLD, a

of reference indicate corresponding parts in the several views.

The frame .1 is inclined to the horizontal and is supported b the base 2, to which it is bolted by the bolts 3. Guides 4, 5 areattached to the frame 1, and the sides of the block 6 are grooved to receive the said guides 4, 5 and slide thereon. The front end 6 of the block 6 is curved to fit the eeled and sized fruit. A rocker-arm 7 is, eyed to a shaft 8 mounted in the bosses 9, 10 near the bottom of opposite sides of the base 2. The provided with set-collars 11. Links 12 connect the up er end of the rockerarm 7 with the rear enc 6 of the block 6 by the pins 13 and 14 respectively. A gear 15 is secured to the shaft 16 journaled in the box 17 in the side of the base 2. The gear 15 is provided with a crank-pin 18. A brass block 19 fits over the crank-pin 18 and slides within the slotted portion of the rocker-arm 7. A shaft'20 is journaled in boxes 21, 22 in l the sides of the base 2, and is provided with the inion 23 meshing with the gear 15. The sha t is also provided with a tight and a loose pulley, 24 and25 respectively, outside of the base of the machine, and with a setcollar 28. The slotted ortionof the rockerarm 7 is stiffened by distance pipes 26 between the lugs 7 a and boltsv 27 through said lugs and distance-pipes.

A cross-bar 30 is bolted by the bolts 31 to the sides of and below the forward end of the frame 1. A similar cross-bar 32 is bolted by the bolts '33 to the raised sides 1" of the frame 1. These bars 30, 32 are provided with slots 30*, 32 respectively, in which are placed a plurality of small bars 34. One end of each bar 34 is threaded and provided with a nut 35, and the other end is provided with a pin 34. The ends of a knife blade 36 are hooked on the pins 34 of each corresponding pair of bars 34in the slots 30 and 32. The blades 36 are similar to hack-saw blades with a knife edge in lieu of teeth. These blades 36 ass through slots 1 in the frame -1 at its ront end, with their cutting edges downward. Tension on the blades 36 is obtained by tightening the nuts 35. It will be noted that the blades 36 lie in vertical parallel planes, and that their cutting edges are inclined about 30 de rees to the plane of the frame 1. The bloc 6 is slotted to clear the blades 36 when the former is in its forward position. A plate 37 is attached to the top of the block 6 and rojects rearwardly from same. A curved p ate 38 is attached to the front end of the frame 1 and above the crossbar 30.

In operation, starting from the position shown 1n Fig. 1, the peeled and sized fruit rolls down a chute above the machine and encounters the plate 37. The belt, connecting withany suitable source of ower, being now shifted from the loose pul ey 25 to the tight pulley 24, the gear 15 carrying the crank-pin. 18 is revolved, thereby causing the rocker-arm 7 to swing rearward, drawing with it the block 6 which slides on the guides 4 and 5. The fruit rolls on the late 37 and on the top of the block 6 until the rear position of said block 6 is reached, whereupon one fruit drops upon the frame 1 in front of the block 6, and is enga ed by the curved front end 6 of said blocas it now moves forward. Continuing forward, this fruit encounters the blades 36 and is thereb sliced, a shearing cut being effected. The s ices are pushed over the curved plate 38 and dro onto a conveyor (not shown) by which they are delivered to the sorters and packers.

The uice runs down the central portion of the frame 1, and is caught by a trough under the lower edge of same (not shown.)

I claim:

1. An improved slicing machine having in combination an inclined frame-work having a series of parallel slots at its front end, two cross bars extending parallel witheach other and spaced apart and arranged in different above said slots, a corresponding tension of the cutters may inclined, the forward end of said vertical planes, a series of blades or cutters upwardly provided with parallel longituextending between the cross bars having I frame being y their opposite ends connected to the latter, dinal slots, a feed chute connecting with said one of said cross bar's being disposed below frame, a plunger reciprocable in the ,frame and the other above the plane of said slots l and beneath the delivery end of the feed whereby intermediate portions of the blades\ chute, said plunger having an extension extend through the slots, means for feeding l forming a e bottom for said chute material to said blades and means for regui whereby the extension supports the fruit and lating the tension of said blades. allows the same to dro 1nto the range of 2. An irn roved slicing machine including action of the plunger w en the latter is rean inclined rame-work having parallel longitracted until its front end uncovers the end tudinal slots formed in its front end, a cross of the chute, a series of parallel longitudibar fixed in the upper portion of said frame l nallyextending blades inclined relative to cross bar the inclination of the frame, said blades exfixed to the front end of the frame below said i tending through said slots, a cross bar in the slots, blades or cutters extending at an anupper portion of the frame, a second cross gle to the inclined frame-work and passing bar in the front of the frame below said slots, through said slots, bars at the ends of the bars connected to the ends of the blades or cutters extending longitudinally in line therecutters and extending throughthe cross bars with, said last-named bars extending through and forming longitudinal extensions of said the crossbars and having means whereby the '3 blades, and means cooperating with the lastbe adjusted, and named bars and the cross bars for regulating a block or plunger reciprocable within said i the tension of the blades. frame-work adapted to feed the material to be cut beneath said cutters. l 3.
