WILLIAM M. HOWLAND, OF LEOMINSTER, MASSACHUSETTS, ASSIGNOR TO HIMSELF AND JOHN H. LOGKEY, OF SAME PLACE.

IMPROVED FRUIT-PARING MACHINE.

Specification forming part of Letters Patent N0. 411,044, dated August 30, 1864.

To all whom it may concern:

Be it known that l, WILLIAMM. HOWLAND, ot' Leominster, in the county of Worcester and State of Massachusetts, have invented a new and useful improvement in the construction of knife heads or stocks for machines for paring fruit or vegetables and I do hereby declare that the following is a full, clear, and exact description of the construction and operation thereof, taken in connection with the accompanying drawings, making a part of this specification, in which- Figure l is a front elevation. Fig. 2 is an end elevation. Fig. 3 is a plane; and Fig. 4 is a vertical section on the line x of Fig.

rl`he subject-matter of my invention is an improvement in the mode of constructing the knife head or stock of a fruit-paring machine, and consists in combining in the same knife head or stock the mode of operation described in Letters Patentgranted to Ephraim L. Pratt October 4,1853, with the mode of operation described in Letters Patent granted to Horatio Keyes June 17, 1856, by which the beneficial results due to both modes of operation are realized in the same machine.

In the drawings, A represents the knifestock, which is constructed with a lip, B, to rest against the fruit; anda is the knife. rlhe stock is jointed to a bail or yoke, 0, at d, which permits it to vibrate in a vertical direction to conform to the surface of the fruit, and is constructed substantially as is described in the Letters Patent ot' E. H. Keyes before referred to. The yoke C is jointed at e to the extremity of the bent arm D,b y which the kni'e is held in the machine and by which it is carried over the surface of the fruit to pare it. This joint permits the knife to have a vibrating motion in a plane transverse to the first, and in this respect itsmode of operation is substantially like that described in the Letters Patent of E. L..Pratt before mentioned. The extent ofthe vibrations in a vertical direction is limited by the stops fand g, and those in a horizontal direction by the stops hand i, the position of the knife-stock at the limits of vibration being shown by thc red and blue dotted lilies in Figs. 2 and 3. This mode of constructing the knife-stock may be employed in paring-machines with advantage in connection with any suitable devices for holding and rotating the fruit, and for carrying the kni'e over its surface.

Having thus described my improvement, what I claim is- The employment in the same knife-stock of suitable devices for giving to it a Vibratin g or rocking movement in a plane transverse to the plane of revolution ofthe fruit, in combination with a vibrating or rocking movement in a plane coincident with the plane of revolution of the fruit, substantially as described.

Executed at Leominster this 18th day if June, A. D. 1864.

IVM. M. HOWLAND.

In presence of- JAMES BENNETT, LUTHER STONE.
