OSCAR SAYRE, OF ANGERONA, WEST-VIRGINIA..-

APPLE-CORER.

SPECIFICATION forming part of Letters Patent No. 551,099, dated December 10, 1895. Application filed June 14,1894. Serial No. 514,563. (No model.)

To all whom it may concern:

Be it known that I, OSCAR SAYRE, a citizen of the United States, residing at Angerona, in the county of Jackson and State of Vest Virginia, have invented a new and useful Apple Corer, of which the following is a specification.

My invention relates to apple-corers, and has for its object to provide a simple, inexpensive, and efficient device adapted to simultaneously core and divide an apple, two sets of cutters being employed to provide for continuous operation, the cutters operating alternately.

Further objects and advantages of this invention will appear in the following description, and the novel features thereof will be particularly pointed out in the appended claim.

In the drawings, Figure 1 is a perspective view of a device embodying my invention. Fig. 2 is a vertical central section of the same. Fig. 3 is a detail view of one of the plungers. Fig. at is a detail transverse section of the operating-gear and the contiguous parts of the device to show the means for mounting said gear. Fig. 5 is a plan view of a modified form of cutter.

Similar numerals of reference indicate corresponding parts in all the figures of the drawings.

1 designates an elliptical frame spanned longitudinally by an arch 3, having vertical sides or standards 2. Arranged within the elliptical base or frame 1 and concentric with the foci thereof are core-knives 5, and radiating from said core knives are straight knives.

The arch is provided with a parallel-sided slot 6, in the sides of which are formed bearings 7 and 8, the bearing 8 being larger than the bearing 7 and being adapted for the reception of the hub 10 of the gear 9. Extending through the central opening of the gear and through the aligned bearing 7 in the arch is a spindle 10, to which the gear is keyed, said spindle being provided with an operating-handle 12.

Mounted in the ends of the slot 6 are staffs 13 of plungers 16, said plungers being adapted to force apples upon the upper sharpened edges of the knives, and the staffs are provided at their inner sides with racks 15 for engagement, respectively, by opposite sides of the gear. Secured in the ends of the slot 6 and embracing the outer and lateral surfaces of the plunger-staffs 13 are the fixed channel-guides 14, which hold the staffs with the racks in engagement with the teeth of the gear.

- From the above description it will be seen that the operation of the plungers is alternate,whereby an apple may be arranged upon one of the core-cutters, while the plunger which co-operates with the other core-cutter is in its depressed position, or as it approaches its depressed position, whereby the operation of the apparatus is substantially continuous.

In order to reduce, as far as possible, the weight of the corer, the arch is made hollow, as shown in Figs. 2 and 4, and hence the use of the channel-guides 14 provides the requisite bearing-surfaces for the plunger-staffs and strengthens the same to prevent displacement of the parts due to the lateral thrust of the gear.

In the modified form shown in Fig. 5 intermediate cutters 17 are employed to divide the fruit into smaller pieces.

Various changes in the form, )roportion, and the minor details of construction may be resorted to without departing from the spirit or sacrificing any of the advantages of this invention.

Having described my invention, what I claim is- The herein described apple corer, the same comprising an open elliptical base or frame provided with core and straight cutters, an arch spanning the base longitudinally and provided with a parallel-sided slot, vertical channel-guides arranged at the extremities of the slot and extending above and below the arch, a gear mounted in bearings at the center of the arch and having a spindle and means connected thereto for operating the gear, and plungers having staffs mounted in said channel-guides and provided at their inner sides with racks in engagement withopposit-e sides of the gear, whereby reciprocatory movement in alternate directions will be imparted to the plungers, substantially as specified.

In testimony that I claim the foregoing as my own I have hereto alfixed my signature in the presence of two Witnesses.

OSCAR SA'YRE. Vitnesses:
