Specification of Letters Patent.

Patented Dec. 12, 1905.

Application filed December 5, 1904. Serial No. 235,588. 4

To aZZ whom, it may concern;

Be it known that I, STEWART L. CAMPBELL, a citizen of the United States, residing at the city of Kalamazoo, county of Kalamazoo, State of Michigan, have invented certain new and useful Improvements in Pitting- Machines, of which the following is a specification.

This invention relates to improvements in pitting-machines for peaches and like fruits.

The objects of this invention are, first, to provide an improved pittingmachine by which the pits of fruits, such as peaches, may be removed without tearing or bruising the pulp; second, to provide an improved pitting-machine for peaches and like fruits which is simple and convenient to use and of large capacity; third, to provide an improved pitting-machine for peaches and like fruits which is simple and economical in structure and durable in use.

Further objects and objects relating to structural details will definitely appear from the detailed description to follow.

I accomplish the objects of my invention by the devices and means described in the following specification.

The invention is clearly defined and pointed out in the claims.

A structure embodying the features of my invention is clearly illustrated in the accompanying drawings, forming a part of this specification, in which Figure 1 is a side elevation view of my improved fruit-pitting machine looking from the left of Fig. 2. Fig. 2 is a front elevation view of my improved fruit-pitting machine. Fig. 3 is a detail plan view, the movement of the swinging knife-carrier being indicated by dotted lines. Fig. 4 is a detail side elevation view showing one of the pivoted knives 0 in its inner position. Fig. 5 is a detail side elevation View of the swinging knife-carrier with the knives in position thereon. Fig. 6 is an enlarged detail sectional view, taken on a line corresponding to line 6 6 of Fig. 5 looking in the direction of the little arrows at the ends of the section-lines, showing the manner of securing the pivoted knives. Fig. 7 is an enlarged detail view showing how the pits are engaged by the knives and the twisting movement which is imparted thereto. Fig. 8 is a detail sectional view showing the cams carried by the revolving knife-carrier U for engaging the pivoted knife-carrier, taken on the curved line 8 8 of Fig. 1 looking in the direction of the little arrows at the ends of the section-line. In the drawings similarletters of reference refer to similar parts throughout the several views.

Referring to the drawings, A is the base of the machine, on which are upwardly-projecting standards A. Mounted in suitable bearings, which are carried by these standards, is a shaft B. A knife-carrier 0, having forwardly-curved arms O, is mounted on this shaft. The shaft B is provided with a suitable sprocket-wheel H, which is connected to the sprocket-wheel H on the hub of the grooved pulley I by the chain it. The pulley I is mounted on the spindle H, projecting from one of the standards A. If desired, the machine may be operated by means of the handle I on the pulley I.

Acircular disk C, having knives C formed thereon, is secured on the side of the knifecarrier (1. Outwardly and forwardly curved knives 0 are secured to the arms C of the knife-carrier, so that they form continuations of the knives C. Inwardly-facing curved knives c are pivoted to the ends of the arm C.

When these knives c are in their inner position, they form continuations of the knives a. (See Fig. 4.) Stops c are provided to limit the inward movement of these knives 0.

A bracket (4 projects upwardly from the right-hand standard A. The swinging knifecarrier D is pivoted on the journal D, carried by this bracket. A spring (Z is connected to the arm D and to the journal D, on which it is pivoted. This journal is adjustably secured in the bracket (0 by means of the set-screw d, so that by adjusting the journal the tension of the spring d may be controlled. The pivoted knife-carrier D is provided with a rearwardly projecting outwardly curved arm D. (See Fig. 5.) This arm when the carrier is inits normal position lies alongside of the disk C. (See Figs. 2 and 3.) Secured on the inside of this arm D is a knife E, having a compoundly-curved cutting edge. The curvature of the forward portion of this knife corresponds to the curvature of the knives C. The knives E and O are sharpened on opposite faces, so that when they are in contact they form a single cutting edge.

An inwardly-facing curved knife E is pivoted on the arm D of the swinging knife-carrier. This knife when in its inner position forms a continuation of the knife E. (See Fig. 5, where the same is shown in its inner position by dotted lines.) A spring 0 is secured to the pivoted knife E and the supporting-arm D therefor, so that the pivoted knife is normally held in its outer position. The pivoted knife E is secured to the sleeve E, which is arranged through a suitable boss on thearm D by the pin 6.

A pair of oppositely-arranged set-screws c e secure the parts together. The inner ends of the set-screws e c engage and serve to lock each other. The knives c are pivoted in substantially the same manner.

The operation of the device is as follows: The peach to be pitted is placed upon a knife 0, preferably at the seam of the peach. The peach is carried forward by the knife until it is engaged by the knives E E. It is then slipped along on the knife 0 until it is engaged by the pivoted knife 0. These knives also cut into the pulp of the peach. When the pit is reached, it closes or forces the pivoted knives to their inner positions, in which positions, coacting with the fixed knives, the pit of the peach is entirely surrounded and the pulp practically entirely severed, the pit being engaged by the pivoted knives E and c, as is illustrated by dotted lines in Fig. 1. As the forward movement of the revolving knife-carrier is continued the pivoted knife-carrier is swung backward and outward, thus giving the pita twist and releasing the pulp therefrom. If desired, the halves of the pulp may be grasped at this point by the operator and laid into pans or trays, or they may be permitted to drop. The continued movement of the rotary knife-carrier brings the cams C into engagement with the rollers c on the swinging knife-carrier, throwing the same rearwardly to release the pit. These cams are double cams, so that the swinging arm is returned to its normal position in an easy manner and without noise. In the revolution of the revolving knife-carrier the arms F on the pivoted knives c are engaged by the curved plate Gr, which returns the knives to their outward position. (See Fig. 1.)

My improved pitting-machine is very desirable, as the pits are removed without bruising or tearing the pulp, which is of course very desirable and of very great advantage. The same is very convenient to operate and is of large capacity. I have illustrated and described the same in detail in the form preferred by me on account of its simplicity in structure and operation. I am, however, aware that it is capable of very great structural variation without departing from my invention.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is
