FRUIT OR VEGETABLE PARER.

SPECIFICATION forming part of Letters Patent No. 759,264, dated May 10, 1904.

Application filed April 18, 1903.

To all whom it 11110 concern.-

Be itknown that I, MARTIN GLAssnR, a citizen of the United States, and a resident of New York, in the county and State of New York,

have invented certain new and useful Improvements in Fruit or Vegetable Parers, of which the following is a specification.

My invention relates to an improvement in devices for paring fruits and vegetables.

One of the principal objects of my invention is to produce a device of this character which shall be rapid in its action, thus insuring productive capacity, simple, thus insuring cheapness of construction, together with I5 freedom from repairs and derangement, and

'one which shall at the same time be certain and reliable in its action.

Another object of my invention is to provide a locking mechanism which shall stop the operating parts in a certain definite position at the end of each cycle of operations and shall hold the same against movement in either direction until a fresh apple or other fruit has been placed in position for paring.

Other objects of my invention will be seen by referring to the claims terminating this application.

The drawings accompanying herewith represent an embodiment of my invention which 3 is now preferred by me.

In the drawings, Figure 1 is a front elevation of my device, the parts being in the position in which they are locked after paring an apple. Fig. 2 is an elevation from the 3 5 handle side of the machine, the same being at right angles to Fig. 1. Fig. 3 is a front elevation of the working parts of my device, showing the parts in somewhat different position from that shown in Fig. 1. Fig. 4 is a 4 detail plan view of the revolving head, the end of the supporting-arm being broken away. Fig. 5 is a side elevation of the pusher-rod and its attached parts.

Corresponding parts in all the figures are denoted by the same reference characters.

The mechanism of my device may be mounted permanently upon any desired form of support or may be mounted upon a frame designed for attachment to a table or other sup- Serial No. 153,158. (No model.)

port by means of a clamp. The latter is the 5 form of construction herein shown.

The frame 1 is provided with a foot 11, adapted to rest upon the top of the table or other support, and with an arm 12, adapted to project beneath the table, said arm having a clamping-screw 10, adapted to engage the under side of the table. The frame is provided at a suitable distance above the tablesurface with a laterally-projecting arm 21, within which and the main part of the frame is journaled a fork-shaft 2, carrying upon one end a fork 22 and upon its other end a pinion 20. In the frame 1 and in a lug depending from an arm 13 is a shaft 41, having upon one end a pinion 42 and upon its other end 5 the main drivinggear 4, which latter gear meshes with the pinion 20 upon the fork-shaft. Secured to the main driving-gear is a crank 43, by which the same is turned. Instead of a crank any suitable power connections may 7 be made with-this wheel for the purpose of driving the same. in such an event an arm corresponding with a portion of the crankarm would be used for a purpose which will hereinafter appear.

Upon the outer end of the arm 13 is supported a revolving head which consists of a bevel-gear 7, which has its teeth downward and meshes with the pinion 42, by which it is driven. Pivoted upon the under side of this 30 gear are two knife-arms 8, which are connected at a point beneath the revolving head and at such an elevation as to clear the apple being pared by a spring 81, which tends to draw the arms together and to hold the operating- 5 knife 83 against the apple. These knife-arms are secured to rock shafts or pins 84, which have short arms or extensions projecting upwardly through slots in the head, said upper end 80 being adapted to engage a double cam 9 or wedge 82, which is pivoted at 85 to the lower side of the arm 13 immediately over the gear. This cam is designed to assist and accelerate in the lifting of the knife-arms in their passage over the fork-shaft. One edge or camsurface of the cam 82 projects beyond the periphery of the bevel-gear slightly, so as to be engaged by the pins or projections 73, carried by the gear and projecting upwardly from the same just outside its periphery. The other cam-surface is adapted to engage the upper end 80 of the knife-arms, so that when engaged by one of the pins 73 the knife-arm will be quickly thrown upward and so held for a short distance until it has passed the forkshaft and frame. It will be noticed that two of these pins 73 are provided and located diametrically opposite upon the gear. The gear is designed to have a half-revolution only during one cycle of operation-that is, during the paring of one apple. To insure this action, I have provided a stop mechanism which is combined with a push-0E member in such a way that the operating parts are locked against turning in either direction until the push-off member has been returned by the placing upon the fork of another apple in position for paring. This mechanism comprises a shaft 3, mounted in bearings upon the frame and approximately, but preferably not exactly, parallel with the axis of the fork-shaft. The inclination of this shaft is shown in Fig. 5 and is approximately the same both to the horizontal and vertical planes. Upon its rear end or the end farthest removed from the fork is mounted a head 30, which constitutes a detent. This head or an arm projecting therefrom when in the position which it would occupy after pushing ofi an apple projects into the path of a stop 40, carried by the gear 4, so that the gear may not be turned in one direction. In this position the end of the shaft at the fork is projected to such a position that a plate 32, carried thereby, is nearthe outer end of the fork. This plate projects toward and preferably slightly embraces the fork, so as to engage the back side of the apple to push it off. This pusher-head may also carry a small knife 33, adapted to remove the skin from the cavity at the stem or blossom, as the case may be. IN hen a fresh apple is placed upon the fork, the pusher will be pushed backward, and consequently will free the stop 40 of the main gear. hen the gear is given one complete rotation, a cam 44, carried by the crank 43, engages the head 30 upon this end of the pusher-rod and forces it outward to push the apple off the fork. A spring 31 engages this pusher-rod or its head to slightly return it after it has been pushed outward by the cam. As a result of this it is projected behind the cam in such a way that the wheel cannot be turned backward. The head therefore lies between the cam 44 and the stop 40, thus locking the parts against movement in either direction.

The operation of my device is as follows: Commencing with the parts as shown in Fig. 1 an apple or other article to be pared is forced upon the fork, and in doing so it engages the plate carried by this end of the pusher-rod and releases the mechanism, so that it may be turned. The crank and gear attached thereto are then given one complete turn. This causes the fork to revolve and the head carrying the knife-arms to also revolve, the latter, however, making but half a turn. As the crank completes its revolution the cam 4C4, carried thereby, engages the head upon the backward end of the pusher-rod, forcing it outward and pushing the apple off the fork. At the same time it engages the stop upon the main wheel to prevent its forward movement and drops behind the cam 44, so as to prevent rearward movement.

I do not desire to be understood as limiting myself to the details of construction and arrangement as herein described and illustrated, as it is manifest that variations and modifications may be made in the features of construction and arrangement in the adaptation of the device to various conditions of use without departing from the spirit and scope of my invention and improvements. I therefore reserve the right to all such variation and modification as properly fall within the scope of my invention and the terms of the following claims.

Having thus described my invention, I claim and desire to secure by Letters Patent 1. In a fruit and vegetable parer, the combination with a rotative main driving member, of a crank for operating said driving member, a detent, means whereby the placing of the fruit in position will move said detent into inoperative position, and means on said crank for bringing said detent into engagement with the rotative member at one point in the latters movement whereby to lock the latter and prevent it from turning.

2. In a fruit and vegetable parer, the combination with a rotative main driving member, of acrank for operating said driving member, a detent, means whereby the placing of the fruit in position will move the detent into inoperative position, and a cam carried by the crank and designed to engage the detent and move it into engagement with the rotative member.

8. In a fruit and vegetable parer, the com bination with a rotative main driving member provided with a stop and acam in advance of the stop, of a detent, means for pressing the detent into the way of said cam and stop, and a pusher connected to said detent, a fork, and means whereby the placing of fruit on the fork will free the detent from said stop.
