My invention relates to improvements in apparatusv for preparing cabbage or like vegetables or fruit for cutting into shreds.

An object of the invention is to provide novel means for ready removal of the outer leaves of the cabbage or like vegetable.

A further object is to provide means to cut the cabbage prior to slicing to cause the slicing to result in shreds or narrow strips 15 instead of slabs.

Another object of the invention is to provide means to so cut or shred the cabbage core prior to slicing that the cabbage remains intact until sliced. 7

Another object is to provide means for moving the vegetable relative to the cutters during the cutting operation.

Other objects will appear from the accompanying description, claims and drawlngs.

The invention consists in the features and combination and arrangement of parts, hereinafter described and particularly pointed out in the claims. In the accompanying drawings Figure 1 is a front elevation of my machine. I

Referring to the drawings, the numeral 1 designates the cabbages mounted on vertically slidable supports or holders 2. The sup ports 2 comprise a holderportion 2 and a square stem, 2, having a roller 3 mounted on line at the lower end of the stem (see Figs. 12 i.

and 18). The vertically slidable supports are guided in apertures 4: in a rotary table 5 by guides 6 secured beneath the table. A stationary cam 7 is provided with which the rollers 3 cooperate to support the slidable holders 2 and to cause the holders to reciprocate vertically as the table 5 rotates.

The table 5 is provided with a shaft 8,

which is driven through gear 9, and pinion 10 from drive shaft '11, which may be rotated'by a belt on pulley 12 or in any suitable way as by a motor. The shaft 8 is supported rotatably in vertical position in. frame 13 at bearings 8 and 8 The frame also supports the cam '7. The table shaft 8 is extended above the table to carry the support for the cabbage cutters or knives 1 1 and the electric motors 15 for driving the cutters. Means for transmitting. electricity to the motors which are revolving with the shaft 8, are designated generally by the numeral 16 and will be described hereinafter.

Four motors 15 are provided, and each one is in a driving connection with one of the core shredder knives or cutters 1 1. The motors 15 and the cutters and their connections are all mounted on a support 3 1 carried by the shaft 8 and rotatable therewith; p The driving connection between each motor "15 and its knife or cutter 1 1 is shown in Fig. 9 and comprises upper and lower bevel gears 17 and 17 driven in common by pinion 18 of motor 15, and rotatably carried 1n housing 19 by bearing sleeves 20 and 20*.

The bevel gear members 17 and 17 have opposed dished portions 21 and 21 with flaring walls 22 with an interposed space 23. In this space is disposed a chuck 24 keyed at 25 to the cutter shaft 26 which is rotatably disposed within bearing sleeves 20 and 20. By raising or lowering the chuck friction connection with either bevel gear is established. At the lower end of the cutter shaft 26, is carried the core shredder knife or cutter 14 (see Figs. 10 and 11), having screw point 14 and blades 14*.

Circular trimmer knives 27 having cutting edges 28 are carried by circular guards 29 and are adapted to surround the core shredder knives. The guards 29 are provided with vertically disposed rods 30 having slidable connection through apertured lugs 31 on the outside of the gear and clutch housing 19 so that the guards and trimmer knives may raise or lower relative to the housing 19 and to the cutter 14 and its shaft. Springs 32 are provided surrounding the rods 30 and bearing against the lugs 31 and the guard 29 to urge the guard and trimmer to lowermost position as limited by nuts 33 on the upper end of the rods, and to yieldingly resist upward movement of the guard. The removable mounting 35 of the motors 15 in the bracket 34 is shown in Fig. 9 where the motor is shown mounted on a platform which is removably secured in bracket 34 by means of bolt 36 and plate 37.

The plan view of the rotary table 5 shown in Fig. 2 illustrates the disposition of the slidable cabbage holders, and shows a cabbage deflecting member 38 which engages the 'cabbages as they travel with the table 5 after they have been subjected to the cutting operation and throws them ofi to one side where they may be collected and conveyed to a slicing machine. The deflector 38 is supported by a standard 39 secured to the frame 13, so shown in Fig. 1 and is so I disposed that the table 5 can rotate beneath it. The table and its shaft in this embodiment of the invention are rotated to the right. As shown in Fig. 1 springs 40 are provided between the table and the lower ends of the cabbage supports 2 to urge the slidable supports forwardly and upwardly so that the rollers will start up the incline of the stationary cam easily. The stationary cam 7 comprises part a upon which the rollers bear, and part b which confines the rollers to contact with part a on its descent from the apex a of part a. The part b is supported by brackets 41 secured to part a.

Referring to the electric transmission means, a stationary electric terminal plate 42 is supported by standard 39 at the upper end ofshaft 8 and in the bore 43 of which the shaft 8 rotates. The electric terminal plate 42 comprises a metal portion 42 carrying a wooden electric terminal and brush supporting portion 42 Supports 44 for carrying the electric terminals and brushes are screwed into the wooden plate 42 A revolving electric transmitter 45 is secured to shaft 8 and rotates therewith. This connection and the connection of the wood and iron portion of terminal plate 42 is clearly shown in Fig. 8 to be by means of screws 46 and 47. The transmitter 45 is made up of a wooden body provided with upper and lower contact rings 48 and 49 from which conductors 50 and 51 extend and carry the current to the motors 15. The brush 52 engages contact ring 48 and the brush 53 engages contact ring 49 as shown.

In the operation of the machine the table is rotated and the electricity is turned on. The cabbages are placed in the holders or slidable supports and as the table rotates, the rollers are carried up the incline ofthe cam thereby elevating the holders with the cabbages thereon.

The cabbage contacts with the circular trimmer knife and with the screw point of the core shredder knife when the roller of the cabbage support is part way up the incline of the stationary cam. From this point upward in the movement of the cabbage support the trimmer knife assembly, by means of the slides and springs, yieldin'gly holds the cabbage against the support. The trimmer knife also on contacting with the cabbage severs the undesirable outer leaves at the core so that they fall ofi or may readily be removed. The guard in which the circular trimmer knife is mounted limits the entrance of the ring knife into the cabbage.

When the cabbage contacts in its upward movement with the screw point of the core shredder knife, the knife and its shaft are lifted, the shaft carrying the chuck upwardly into frictional contact with the upper gear. This causes the knife shaft to so rotate that the screw pointof the knife shaft will screw down into the cabbage core as the cabbage continues to be lifted by the roller riding up the cam incline. When the screw has entered the cabbage the blades of the knife will make a spiral cut down through the cabbage. The stationary cam is so designed that the core shredder knife will have cut all the way through the core. of the cabbage when the apex of the cam is reached by the roller.

When this point in the operation is reached, the core shredder knife and its shaft are no longer pressed upwardly by the cabbage, but will be forced down thereby by the holding action of the trimmer or assembly on the cabbage and by the action of the upper cam portion 1) on the roller, thus breaking the drive connection between the chuck and the upper gear and establishing adrive connection between the chuck and the lower gear. This causes rotation of the core shredder knife shaft in the reverse direction causing the knife to work its way relatively upward through the spiral cut in the core, as the roller descends from the apex of the cam, and the cabbage and support descend with it until the cabbage is entirely clear of the core shredder knife and is ready to be removed from the machine. 'During the entire core cutting and knife withdrawing operation until the cabbage is clear of the core knife, the trimmer knife assembly holds the cabbagesecurely in place on its vertically reciprocating holder or support.

The incline of cam face is relative to the pitch of the core shredding knife.
