CHARLES W. HOTTMAN, OF PHILADELPHIA,

PENNSYLVANIA, ASSIGNCR OF ONE-HALF TO y CHRISTOPHER OFFENHAUSEB, OF PHILADELPHIA, PENNSYLVANIA.

MACHINE FOR CUTTING CABBAGE.

Specification of Letters Patent.

Patented Sept. 8, 1908.

T o all 'whom it may concern:

Be it known that I, CHARLES W. HOTT- MAN, a subject of the Emperor of Germany, having declared his intention of becoming a citizen of the United States, residing at Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Cutting Cabbage, of which the followingl is a specification,

My invention relates to improvements in devices for slicing vegetables, particularly cabbage, and is designed to overcome the dead center common to cutters in which rotary knives are employed and thereby obviate the central grinding action which not only hasa tendency to bruise the product but also tends to retard the free cutting action of the knives.

My invention further embodies a means for adjusting the knives with respect to the plate by which they are carried for the purpose of gaging the thickness of the slices to e severed from the mass of material acted upon.

My invention will be more fully understood by reference to the accompanying drawings, in which:

Figure 1 illustrates a plan view of my vegetable cutter. Fig. 2 represents a front elevation of same. Fig. 3 denotes a vertical section on a line 3 3 of Fig. 1. Fig. 4 shows a detached lan view of the rotatable knife plate, the {nives being removed to show the shape of the openings formed to receive them. Fig. 5 illustrates a detached plan view of the knives and the spider by which they are supported. Fig. 6 represents a transverse section of the knife plate with the knives in position the section being taken approximately on line 6-6 of Fig. 4. Fig. 7 shows an enlarged section of a portion of the knife plate and a portion of one of the knives the purpose of which is to illustrate the relative position of one with respect to the other, and Fig. 8 illustrates a section similar to that shown in Fig. 6 except that the means for supporting and adjusting the knives has been slightly modified.

Referring to the reference letters of the drawings, A, represents the hopper; B, the cutter plate; C, the vertical shaft on which the cutter plate is fastened; I), the horizontal driving shaft; F, the fixed vertical shaft; and, G, the bracket carrying the shaft C.

l, The lshaft C, is mounted in suitable bearings in the bracket G, and is provided with a pinion 7L, which meshes with a gear wheel II, fastened to the fixed shaft F. The bracket G, is connected to a bevel pinion E', by means of a sleeve c which loosely surrounds the shaft F, but is fixedly secured both to the bevel pinion and to the bracket. The beveled pinion E', meshes with a corresponding gear E, which is mounted upon a driving shaft D, rovided respectively with fast and loose pu leys D and D2. rPhe shaft D, is journaled in bearings I' I', projecting from a bed plate I, which is also rovided with a column I2, which supports tIie fixed shaft F. The hopper A, is sup orted by uprights A', A', projecting from tlie bed plate I, and is provided with an inclined chute A2, to carry off the finished product.

cent-shaped openings B', in which rest the knives B3. These knives are fastened to a spider as shown in Fig. 5, the same consisting of a hub B2, having an opening h3, which embraces a corresponding hub B5, on the cutter late B, and arms b2, b2, etc., to which the nives B3, are fastened. The spider together with the knives is vertically adjustable with respect to the plate B, for the purpose of gaging the thickness of cut, and to this end is provided with a special spring S, located between the plate and the hub B2 -of the spider and tending normally to press the latter down. The hub B5, is threaded at or near the bottom to receive a nut BG, which bearing against the bottom of the hub B2, may be turned to force the spider upwards against the action of the spring S. A similar construction is shown in Fig. S, except that the knives B3, are mounted upon independent lates 612, 612, which are fastened to studs L, and these are held by projecting arms K, K, connected to or forming part of the hub of plate B. The adjustment is similarly made by means of nuts M, M, acting against the action of springs S', S'.

The operation of the machine is as follows: IVhen the shaft D, is rotated it imparts a rotary motion to the bracket G, through the medium of the bevel gears E, and E', and as the shaft C, is journaled in the bracket G, it is also turned and describes a circle concentric to the wall or rim of the hopper. I/Vhile this rotary motion of the shaft C and bracket G, is taking place the shaft C, is also caused The cutter plate B, is provided with cresto turn in its bearings by the pinion h, on the l and rovided with bearings to receive the ro shaft C engaging a gear H, iixedly secured to the stationary shaft F, and thus it Will be seen that the cutter plate B, is given two motions, one on its own axis and another on an axis of which the shaft F, is the center.

Having described my invention what Il claim and desire to secure by Letters Patent is:

- A vegetable cutter comprising a hopper, a cutter plate arranged below the hopper, a rotatable shaft supporting said cutter plate, a bracket loosely mounted upon a fixed shaft tata le shaft, a gear Wheel secured to the fixed shaft, a pinion in en agement therewith secured to the rotatable s aft, a bevel pinion fastened to said bracket and a bevel gear engaging the same mounted upon a shaft suitably driven, substantially as specified.

In testimony Whereofl aflix my signature in presence of tWo Witnesses.
