which the following is a specification.

"My invention rel'atesto improvements .-in beetcutters inwhi'chthe knivesand knife blocks are held in a stationary positionand the beets are rotated during the cutting or i slicing operation.

The objects of this arrangement are primarily to increase capacity over existing machines, to facilitate. inspection,-removal or renewal of knives and knife blockswhile the cutter is inoperation. Another object is betterslices or cossettes,as they are/known in" the beet sugar manufacturing industry, as centrifugal force does not break the. cossettes at high rotational speeds in my cutter. Centrifu al force instead aids in cansingthelieets to track and therefore produce uniform cossettes. I I

Iattain these objects by the mechanism illustrated in the accompanying drawings.

Figure 1 is ahalfsectional plan of assenr bled'cutter taken at CDof Figure 2 and halffull plan. Figure 2'is a sectional elevation of assembled cutter taken at AB of Figure 1. Figure 3 is a sectional plan of a knife block and one guide taken at E--F of Figure 1. Figure 41 is an elevation of a knife block and one guide viewed from the inside or cutting side. Figure 5 is a sectional elevation of a knife block taken at GH of Figure 3. Figure 6 is a part plan of a blank knife block. Figure 7 is a sectional elevation of the guide and frame taken at JK in Figure 3. Figure 8 is a sectional elevation of a feeding device taken at LM in Fig. 9. Figure 9 is an elevation of a feeding device.

Similar numerals refer to similar parts thruout the several views.

The casting land the semi-rings 1 and 1*, Figures 1 and 2 constitute the main frame which are in turn supported on any convenient structure such as I beams 3 and 3 In casting 1 are provided stone pockets 1 with retaining bars 1. The inverted cone hopper 4: is attached to the rings 1 and'l The blank knife block half rings 5 and 5 are supported from casting 1. The knife block ring 6 is also supported on rings 5 and 5 and casting 1. The vertical bearing 7 is carrie'don c'astingl 'and inturncarries shaft' 8. The impeller 9 is attach-ed to shaft 8. With in impeller- 9 are "the vanes 1-9, Directly abovebut not attached'toimpeller '9 is" the feed hopper 10. The shaft 8 is driven thru bevel gearsdl and 12,iwhich' in turn are driven= thruf shaft 13 and clutch pulley 1 1. The shaft 13 i's' 'supportedby bearings 15, 15 and15 Gears 11 and 12ar'eenclosed in casing 16.

ring- 6 areof' the conventional design and are shown in larger detail in Figures 3, 4 and'5. Thelolank flknife blocks 18 are carried in the-"rings 5and 5 These blank knife' blocksha ve; practically the sameidimensions as the knife :block' 17. When the knife bloc-ks 17' are removed from. the ring 6 the-blankknife blocks 18 slide'into their place in'ring G-fromrings 5iand 5 'When the blocks 17' and 18 arein place in? the rings a 6='and '5 "and '5 their position is shown in Figure 5. The h'eads'ofthebolts 17 hold the blocks 17 and 18 together as a unitwhile in"the'" rings 6,5 and 5. "When the blank block-18 is in the ringG in theplace offthe knifeblock 17,- it is j attached or detached from'the knife block 17 by sliding in or'out, the bolts '17? coinciding lvvithslots 18 -Theknife block 17"is conventional and is composed of the frame 17 b which carries the standard corrugated knives 17 and the corrugated rocker bar 17 The knife blocks 17- are held in ring 6 by a removable corrugated stop bar 19, which is secured to the ring 6 by dowel pins 19 and bolts 19".

The object of having bar 19 removable is to be able to substitute a bar with corrugations to coincide with those of the knives 17 The feeding device shown in Figures 8 and 9 is comprised of the stationary hopper 10 With a baffle plate 10. Directly below hopper 10 is the rotating impeller 9. Within the hopper 10' is a multivaned feeder 10*, I

secured to and driven by shaft 10, which in turn is secured to and driven by pulley 10 The belt 20 drives the pulley 10 at the required speed from shaft 13 and pulley 13.

The operation of my beet slicer is as follows: The beets are deposited into stationary hopper 10 and are fed by the feeder 10* into the rotating impeller 9. Centrifugal force throws the beets against the stationary knife blocks 17. The beets are prevented from sliding or rotating in the impeller 9 by the vanes 9*. r

The stationary knives 17 in blocks 17 present sharp edges against which the beets are moved at a high peripheral speed, resulting in a continuous stream of slices or cossettes being deposited from the knives 17 into the hopper 4,

. Should any foreign matter, like stones, find its way into the cutter it will be lodged in the stone pocket 1 and can be removed by the raising of barsl.

I claim: r

L'In a beetcutter, the combination of stationary slicing elements, a rotating element having a centrally located inlet passage diverging into a plurality of spiral peripheral outlet passages which match with the stationary slicing elements, and blank elementsin position to be substituted for the slicing elements.

2. In a beet cutter, the combination of a feeding device, a horizontal rotating element having an inlet opening concentric above its vertical axis, the inlet opening being partitioned by vanes to form a plurality of outlets, stationary cutting elements with which said outlet passages coincide, blank elements in position and adapted to be substituted for said cutting elements, and means for driving the feeding device and the horizontal rotating element.

3. In a beet cutter, the combination of a feeding device, a horizontal rotating element having an inlet opening concentric above its vertical axis, the inlet opening being partitioned by vanes to form a plurality of outlets, stationary cutting elements with which said outlet passages coincide, blank elements in position and adapted to be substituted for said cutting elements, means for driving the feeding device and the horizontal rotating element, means to receive hard or foreign substances, and removable means whereby said foreign substances are removed from the machine.

4:. In a beet cutter, the combination of a rotary impeller having a central inlet and a plurality of lateral outlets, removable knife blocks concentric therewith, and means for receiving and removing hard or foreign substances from the machine.

5. In a beet cutter, the combination of a vaned type of feeding device, means for driving the same, a horizontal closed vaned type of impeller rotating therebelow, means for driving the impeller, the impeller having peripheral openings, removable stationary knife blocks, blank blocks adapted to be substituted therefor, and slotted concentric rings for holding said blocks in a definite position.

6. In a beet cutter, the combination of a rotary impeller having a central inlet and a plurality of lateral spiral outlets, vertically slidable knife blocks concentric therewith, and blank blocks removably attached at the lower edges thereof.

7 In a beet cutter, the combination of a rotary impeller having a central inlet and a plurality of lateral outlets, vertically slidable knife blocks concentric therewith, blank blocks having slotted laterally extended flanges at the upper edge, and bolts extending through the slots in the flanges into the lower edge of the knife blocks.
