FRUIT-PARING MACFHNE.

SPECIFICATION forming part of Letters Patent 130,340,937, dated April 27, 1886.

Application filed September 21,1885. Serial No. 177,729. (No model.)

T0 at whom it may concern:

Be it known that I, HERBERT COTTRELL, a citizen of the United States, and a resident of Newark,county ofEsseX, and State of New Jersey, have invented a new and useful Improvement in Fruit-Faring Machines, of which the following is a specification.

My invention relates to a rotary cutter for fruit-paring and to the means employed to actuate it,

My object is to provide simple and effective means for supporting the cutter-spindle. and for guiding the movement of t-heannular cutter toward and away from the fruit during the process of paring and after its completion. I secure this object by journaling the rotary spin dle, which carries the cutter in a supportingarm, and imparting to said arm a variable movement by means of a stationary eccentriccam,which it traverses, by mechanism hereinafter described.

Figure 1 represents a front elevation of my improved parer. Fig. 2 represents a plan View. Fig. 3 represents a plan view of the supporting-arm and the cutter-spindlc which revolves therein detached. Fig. 4 represents a cross-section of the arm and cutter-spindle drawn on line Y Y of Fig. 3. Fig. 5 represents a cross-section of the arm and spindle drawn on line X X of Fig. 3.

Like letters and figures indicate like parts.

Z is the main frame, carrying the several gear-wheels which actuate the annular cutter 2 and rotary fork T, having tines l0. JDh-e fork is rotated through action of driving-wheel M, intermediate gear-wheel, N,and gear-wheel O, the lastnamed wheel being rigidly secured to the base of the fork-spindle T at 18. cutter-spindleBreceivesits variablemovement around cam F through drivingwheel M, spindie 14, spur-wheel I, and wheel G, with which the spur-wheel gears. The supporting-arm O is journaled on the face of said wheel G atD D, (shown in Figs. 1 and 3,) and held in its bearings by plate The bearing of the supporting-arm 0 against the cam F is secured by spring 9, one end of said spring being secured to the arm 0 at 4, the other end to the center of the cam F.

It will be seen that the rotation of the wheel The G will carry the supporting-arm of the cutterspindle 13 around the cam F, and thereby impart to it the required movement toward and away from the fruit.

WVhile the supporting-arm Cis being carried around the cam F the annular cutter 2 is being revolved on its own axis or spindle B. This rotary movement is imparted through driving-wheel M, pinion V, spindle L, having bearings in projecting

studs

11 and 12, gearwheels K and H, the latter loosely journaled on the camsupport and communicating a rotary motion to spindle B through pinion E, carried on the end thereof.

15 is the handle, rigidly attached to driving wheel M.

S is the standard which supports the machine. This standard is secured to the frame Z by means of a dovetail socket, into which it fits, and tothe table by means of aflanged foot and clamping-screw 19 connected therewith.

The supporting-arm (3 and parts connected therewith are best shown in Fig. 3. The form of the arm is that of a half-sleeve longitudinally, having covered bearings for spindle B at 7 and 8. The outer end of the arm forms the guard 3, which governs the depth of the out while paring. I

A is the cutter-head, carried by spindle B, and 2 the annular cutter thereon.

5 is a slotted piece held by set-screw 6to the projecting plate 4, made part of arm 0. This piece 5 projects under and nearly touches the annular cutter when in place. Its function is to prevent the cutter from leaving the cutterhead and its inner surface from being clogged by the fruit-skins during the process ofparing.

The annular cutter2 is simply a strip of thin steel having one of its edges sharpened,and so bent in circular form as to adapt itself to the annular groove in the cutter-head A by its own elasticity. The two ends of the circular strip are kept sufficiently apart on the cutter-head to enable the sharp-edge angle of one end to come in contact with the fruit as the cutter re- Volves.

of the out. By this form of cutter the tendency to scrape the skin without cutting, noticeable in paring peaches with a rotary knife having a continuous cuttingedge, is entirely removed.

This contact secures the initial point ICO 2.
