This present invention relates toa potato cutter and has for its prime objectto provide a machine of this nature which may be power a lower blocks,

driven in order to obtain speed in the cutting of spud potatoes and the like.

Another very important object of the invention resides in the provision of a machine of this nature having a pluralityof cutting frames mounted in-a rotary table in combination with a follower block for forcing potatoes through the frames, and means for simultaneously operating the follower block and rotating the table in proper coordination so that the block will force a potato through a cutting frame as it arrives thereunder.

A still'further very important object of the invention resides in the provision of a potato cutting machine of this nature which is exceedingly simple in itsconstruction, inexpensive to manufacture, strong and durable, compact and convenient in its arrangement of parts, thoroughly efiicient and reliable in use and operation, and otherwise well adapt-' ed to the purpose for which it is designed.

' lVith the above and numerousother obj ects in view as will appear as the description proceeds, the invention resides incertain novel features of construction,-'and in the combination and arrangement-of parts as will be hereinafter more fully described and claimed.

Figure 10 is a fragmentary side elevation I Referring to the drawing in detail, it will be seen that the numeral 5 denotes an elongated-table mounted on suitable supporting legs 6 and having one end 5 in the form of a seat. A cylinder? rises-from the platform ;5 to receive in its upper end a ring 8 on the thereof to receive the. central portions of the transverse knives which have V-shaped notches 19 in their central portions merging into slots 20; On the ends of: the longitudiknife 17 in each. frame. The longitudinal knife has slots 18 rising from the bottom edge nal knife 17 there are ears 21 which are sea formed with notches 22 to rest on thesides 0f the frame.

A bolt 24 extends through an opening in the lower plate 11 and through the platform 5 to hold the table against displacement but permitting it to rotate on the cylinder 7. Rests 25 and 26 rise from the platform 5 under the table T adjacent its periphery. A dog 27 is=pivotally mounted as at-28=toengage with recesses 29 in the bottom of the .table .for holding it .in stationary ,position .as will 'befmorle clearly explained hereinafter. A spring 30 holds the tion. The numeral 31 denotes a follower block having slots 32 in the bottom face thereof to accommodate the knives 1 6 and 17. Arms 33 .are'zfixed :to the .sides of -;the block and .are

The operator, of course, places the potatoes on the frames as they come to rest in front of him and so places the potatoes on the knives of the frame depending upon the numberof pieceshe desires t0 cut the .potato into as will be quite .apparent. It will be noted that when the cran arm 431 s ac u ting the ca c 4.5 to th "left, referring.pa ticular yto F gur 1 Said catch engages the dog to release it from its .recessand this dog will be released in time to engage the next oncoming recess because at .thistimetheprankarm will be swinging in the lower arc of its movement.
