UNITED STATES PATENT OFFICE.

GEORGE BERGNER, OF WASHINGTON, MISSOURI.

IMPROVEMENT IN APPLE-PARERS.

Specification forming part of Letters Patent No. 135,622, dated February 11, 1873.

To all whom it may concern:

Be it known that l, GEORGE BERGNER, of Wa-shington, in the county of Franklin and State of Missouri, have invented a certain Improved Knife-Stock and Gutter-Head for Apple-Parers, of which the following is a specication:

The object is to form a simplified, accurately-operating, and readily constructed and applied outter-head and knife-stock; therefore lthis invention consists in the peculiar construction of knife-stock and cutter-head, and their arrangement and combination in manner now more fully to appear.

Of the drawing, Figure l represents a front elevation with parts removed to show sections; Fig. 2, a front elevation in reverse position to that of Fig. l.

The invention is designed, in application and use, for apple-paring machines, similarly` operating to that described in my patent aforesaid of date January 10,1872. In said patent a sliding rack-rod operates the knifestock, and imparts to same the required motion to revolve the cutter devices. Similarly the sliding rack-rodoperates the knife-stock, here shown, which, for this purpose, has -an armsupport, A, having` its base formed with a part pinion, c. To the end of the .arm A is securely bolted the vertical knife-stock B. The knife-stock B is formed near its upper end with a hollow support, b. This further has a projection at b1, and has its face slotted as at b2. (See figures.) The hollow support b of knife-stock forms a housing to inclose the spring O, which coils round the top of the stock, having one end projecting at c, and the other end, c1, extended to abut a lug, c2, at bottom of cutter-head. The cutter-head D is of the constructive formation shown in figuresits circular base d fitted to cap and turn upon the face of the hollow support b of knife-stock. The cutter-head D is secured to the top of knife-stock by screw-bolt d1.. d2 is a projecting lug forming part of cutter-head, which limits the rotation of same when brought to abut against the projection b1 of knifestock. The slot b2 allows and limits the movementof the spring O and cutter-head D, the latter, in its return movement, being estopped by the lugs d2 and b1 aforesaid. To the.` cutterhead D is suitably attached a paring-knife, E.

The knife E cuts in line with the core of the apple, and, as the slide-motion of the rackrod imparts the required motion to knifestock, the spring C forces theciitter-head carrying-knife against the surface of the apple, which is thus properly pared.

Having thus fully described my said invention, what I claim is-f A knife-stock consisting of the stock B, formed with a hollow support, b, inclosing a spring, O, and carrying a cutter-head, D, and knife E, all constructed to operate as and for the purpose set forth. A

In testimony of said invention I have hereunto set my hand. A .Q

GEO. BERGNER.
