6 Claims.

It is the principal object of the invention to provide a machine that Will receive'an apricot, automatically position the same and then cut it into two parts, and finally discharge the halved .3 apricot and pit from the machine.

It is another object of the invention to provide a machine of the character indicated that is so constructed and arranged that it will operate successfully upon both hard and soft apri- 10 cots in rapid succession.

It is still another object to provide a machine of the character indicated that will be economical to manufacture, simple in form and cohstruction, positive in operation, and highly efficient in its practical application.

Figure 7 is a sectional view on line 'l-l of Figure 6. V

In the particular embodiment of the invention herein disclosed I show at l a supporting framework upon which is rotatably mounted as at 2 a horizontally disposed table 3. The table 3 is rotated in the direction indicated by arrow 4 in any suitable manner as indicated at 5.

Upon one. end of the frame 1 and spaced from the table 3 are mounted vertically disposed brackets 6, and in these brackets are formed spaced, paralleL'and'vertically disposed slots as I.

There are two friction-disc turners, the upper one comprising two angle bars as 8 having longitudinal slots as 9 formed therein and rigidly spaced and connected by cross-bars Hi, the front edges of the cross-bars being arcuate in form as at ll and concentrically disposed relative to table 3. Clamped between the bars i is a rubber friction member i2 which extends beyond the edges ll of bars 10 and has a similarly formed and disposed working edge as l3.

The friction-disc turner 8-43 is adjustably mounted in brackets 6 by means of bolts I4 in 1935, Serial No. 30,607

the slots 1 and't, this mounting permitting both vertical and horizontal adjustment.

The lower friction-disc turner is similarly formed of bars i5 connected by cross-bars it having arcuate edges l? and clamping rubber 5 friction member E8 in place. This turner is also adjustably mounted as at I9.

At 20 is shown a knife having an arcuate cutting edge 2! and mounted upon side bars 22 through the medium of a cross-bar 23. The side bars 22 are slotted as at 23 and are adjustably mounted uponthe brackets 6 by means of bolts 25. The knife may therefore be adjusted vertically or forwardly toward or away from the table 3.

Any desired number of apricot holders may be mounted upon the table 3, but they will, of course, be identical in every detail.

Each holder comprises a yoke as 26 mounted upon the table 3 in any suitable manner as at 2? and extending above and below the same.

A freely rotatable spindle is mounted in the upper arm of the yoke to rotate about a vertical axis and is held against vertical movement by collars as 29. A similar spindle 33 is mounted in the lower arm of the yoke to rotate in axial alignment with spindle 28, but the spindle 30 is also mounted to slide freely along its axis and has a ball thrust bearing 3m mounted in its lower end.

At 3! is shown a track member concentrical- 1y disposed relative to the axis of rotation of the table 3. The central portion of this track passes over the frame i in a horizontal plane but its two ends are inclined downwardly toward the bottom of the frame as shown at 32. The center line of the track lies directly under the path of travel of spindle 33 so that when the said spindle approaches and contacts the track it will ride up on the same and thereby elevate the spindle and the carrier head thereon which will now be described.

Upon the upper end of spindle 30 is fixedly mounted a friction-disc 33. The disc 33 lies in a horizontal plane and has a peripheral friction surface adapted to contact the friction member l8 and be turned thereby.

Slidably mounted in the disc 33 are a number of vertically disposed rods 34, each rod having a head 35 on its lower end to limit its upward movement through the disc 33, and a head on its upper end as 35. A light spring as 31 is mounted on the rod to bear against the disc 33 and head 33 to normally hold the said rod in the fully extended upward position as shown.

The upper spindle 28 is similarly provided with slidable rods 3? having heads 38 and 39 and. fitted with springs 40 to normally hold the said rods in a fully extended and lowered position, the disc 4| in which the rods are mounted being adapted to frictionally engage member 12 to be turned thereby.

When the machine is in operation the upper head member will travel in a circle and at a uniformly constant elevation as indicated at 4 la, but during the longer portion of its journey the lower head member will drop to the position indicated at 33a, being raised to its most elevated position only during its passage over the track 3|.

The friction members l2 and I8 are so adjusted that when the lower head is raised to its most elevated position the discs 33 and 4| will contact the same and identical rotary movements will be simultaneously imparted thereto.

Assuming the machine to be assembled and in full operation as above described, an apricot is placed on each head 333'l as it passes the operator. When the spindle 30 is pushed upwardly by track 3| the apricot is brought into contact with the rods 3'! of the upper head with the result that all of the rods of the upper and lower heads that contact the apricot adapt themselves to its conformation and support it firmly, yet lightly, in position. When the discs 33 and 4| contact their respective friction members [8 and I2 the apricot is rotated and at the same time advanced to contact the knife 26. These parts are so proportioned that the apricot makes one complete revolution as it passes over the knife and is cut cleanly into two parts thereby.

When the lower head has passed off of the track 3| a finger 42 mounted on frame I as at 43 contacts the apricot and pushes it off of said head.

It is to be understood, of course, that while I have herein shown and described but one specific embodiment of the invention, changes in form, construction, and method of assembly and operation may be made within the scope of the appended claims.

I claim:

1. An apricot cutter comprising, an annular horizontally rotatable carrier, vertically disposed fruit holders mounted upon the periphery thereof for movement in a given path of travel, each holder comprising an upper head member, rotatably mounted therein and provided with independently movable and resiliently mounted depending fingers and a lower head member having upstanding independently movable fingers resiliently mounted thereon in opposed relation to said first fingers, said lower member having vertical sliding engagement with said holder, a cam track disposed below the path of travel of the holder to slide the lower member, instrumentalities for rotating said members when they pass over the cam track, and a fruit cutting knife disposed in a horizontal plane and between said members when they pass over the track.

2. In an apricot cutter, a fruit holding device comprising, a yoke and means for supporting the same in a vertical position, a vertically mounted spindle rotatably mounted in the upper arm of the yoke and means for preventing axial movement of the spindle, a horizontally disposed disc mounted on the spindle, fingers slidably mounted in the disc and depending therefrom, resilient means disposed to urge the fingers into said depending position, a second spindle rotatably and slidably mounted in the lower yoke arm in axial alignment with the first spindle and gravity actuated to seat on said arm, a horizontally disposed disc mounted on the end of said spindle adjacent the first disc and in opposed relation to the the first disc, fingers slidably mounted in said last disc in opposed relation to said first rods, and resilient means for supporting said last mentioned rods in an upstanding position.

3. In an apricot cutter, a fruit grasping device comprising a pair of vertically aligned, spaced, and relatively adjustable head members having independently adjustable fingers resiliently mounted thereon to project toward each other from their adjacent ends.

4. In an apricot cutter, a fruit grasping device comprising, a pair of vertically disposed, spaced and axially aligned head members having independently adjustable fingers mounted on their adjacent ends, resilient means between said fingers and their respective heads to urge the fingers into extended positions toward each other, and means operative to change the spacing between the opposing finger ends at predetermined periods.
