ROBERT L. PAPPY, OF DAYTONA, FLORIDA, ASSIGNOR TO EAST COAST PRESERVING COMPANY, OF DAYTONA, FLORIDA, A FIRM.
SLICING MACHINE.
Application filed July 16,
To all w'hon't it may concern:
Beit known that 1. ROBERT L. PAPPY, a citizen of the United States, and a resident of the city of Daytona, in the county of Volusia and State of Florida, have invented certain new and useful Improvements in Slicing Machines, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification.
My invention relates to machines for she ing fruits, and particularly the softer fruits, such as oranges and grape fruit.
In the treatment of such soft fruits oranges, grape fruit, lemons and the like, the great difficulty is to get a clean slicing which is uniform, without mashing up the fruit or crushing it, and the principal object of my machine is to provide an apparatus or machine which will accomplish a proper slicing of such soft round fruits.
In addition to the fundamental object above noted, it is my purpose in this invention to provide a machine which is capable of sufficient speed in operation to'be efficient and of considerable safety against injury to the operator. V 1
These objects and. other advantages to be noted I accomplish by that certain construction'and arrangement of parts to be hereinafter more specifically pointed out and claimed.
In the drawing Figure 1 is atop plan view of the device.
Figure 2 is a end elevation thereof taken from the driving end of the shaft.
Figure 3 is a side elevation of the machine.
Figure 4 is a detail vertical section of the post for detachably retaining the shaft. 7 The machine as shown in the example selected for illustration of the principles of my invention comprises a table 1, which mounts at one end a motor 2, carrying a rapidly revolving knife disk 3. It is this disk which slices the fruit, andv the balance of the mechanism deals with the means for mounting the fruit and feeding it against the knife,
The shaft which is fed towardthe knife is" shown in this embodiment of the machine at 4, and is provided with two journals,
one of which isswiveled, and the other of which is provided with a latch for auto- Specification of Letters Patent Patented Jan. 17, 1922.

matically opening and engaging the shaft during the operation of the machine as will be noted. 1 I
Describing first the latch device, there is a hollow or grooved post 5, within whi h a plunger or latch 6, pressedupwardly by a springT. The housing is mounted in the table by means of a suitable fitting 8,- and is located toward the endof the machine away from the slicing blade. The upper end of the hollow post isprovided with a partial journal member 9 for the shaft 4, and the latch is formed at its upper edge with a journal face 9 to match the face 9 and practically complete the journal for the shaft. The latch further has a beveled contact surface 10 which, when the shaft is forced against it, will cause a depression of said latch. p v 7 In order to'provide the largest possible amount of bearing surface for the shaft in the latch member, I provide for an arcuate path for said member to'assume during'its depression. This path is provided for by means of a pin 11 in the latch anda curved slot 12 in both sides of the post to receive said pin. The latch has an operating finger 6 by which the: operator can depress it to release the shaft, and at its, lowerend the slot '12is formed large enough at 12, so that the pin 11 may be inserted by forcing down the latch beyond the point to which it will be carried after the handle is mounted thereon. l
In advance of the latch post for supporting the shaft is the swiveled post 13, which has secured fast or integral with its'upper end the sleeve '14. This sleeve is cut away as to its upper half adjacent the-middle portion thereof and is'provided with a movable member, 16, which is movable to complete the shaft housing of the sleeve. This memher is hinged at 15 and is threaded at 15 at the portion where it enters the cut-away part of the sleeve. It has also a handle 17 By raising this member, the shaft a is free to slide in thesleeve, but when it is depressed the threads thereon engage'the threaded member, which will permit the easy sliding of the shaft to whatever position is desired.
While I do not wish to confine my invention to the exact form of thread on the shaft and the threaded member, or split nut member, I find it valuable to provide a flat topped thread in order to cut down wear,-- thus a U. S. standard thread cut on an H,- inch rodr For receiving the fruit, the end of the shaft is provided with a dish-shaped plate 18, at the center of which extend a plurality of prongs 19. I refer three in number. The shaft is further provided with lock nuts 20 for limiting the motion thereof to the right, and the nuts 21 for limiting its motion toward the left; considering the ma chine placed as shown in the drawings.
The end of the shaft away from the slicing knife is equipped with a friction wheel 22, having a handle 23for manual operation. For mechanical operation, a drum 24 is mounted on the table of the machine in a position to frictionally revolve the wheel 22. This drum may be driven by a shaft 26, that receives its power from a belt 27 and ulley 28 on the motor that drives the kni e.
As so constructed, the operation of the device is as follows. The operator first releases the latch device so that the pronged end of the shaft can be swung around toward him and away from the knife. He then mounts the fruit on the prongs pushing it home against the dished backing plate. The shaft easily swings on the swiveled post that carries the split nut device, and when the fruit is mounted is swung back, thereby automatically trippingthe latch and entering the journal in the latch post. Maintaining the split nut or threaded member out of operation, the shaft is thrust forward to a point thatwill bring the fruit fairly close to the knife. The threaded member is then lowered and held down by the operator and the friction wheel, or manual operation by means of the handle, will feedfthe fruit slowly. forward as controlled by the threads.
on the shaft.
The knife is set so that it will just clear the prongs, which said prongs should take fruit in a up but little more space than the core of the fruit. The revolution of the knife and the fruit will then cause a slicing of the continuous thin sliver of a depth equal to the threads on the shaft. dished backing plate for the fruit is quite essential, as t holds the fruit against being forced out of shape, andprovides a fairlv large bearing surface for. the end of the fruit away from the knife.
The nuts' are arranged so. that the feed s stopped just before the knife would be in a position to strike the dished backing The.
lieved to be obvious without full explanation. The reason for the frictional drive is among other things to permit the friction wheel. to travel over the drum while it is revolvin It should be clearly understood that either hand or mechanical operation can be used.
The machine can work very rapidly,and does an efiicient slicing-of soft fruits.
It is not desired that my invention be limited to the precise structure of the latch member, or the. threaded member which forces the shaft to travel. Other mechanical devices for accomplishing a like movement could readily be used, my selection for illustration being of parts which are simple of construction and have been proven out as effective in practical work.
Having thus described my invention, what, I claim as new and desire to secure by Letters Patent, is:' V l 1. In a fruit slicer, the combination with a rotating knife and a rotatable holder. for the fruit. mounted on shafts parallel to-but offset from; each other,-and means for ad vancing the holder toward the knife and simultaneously rotating the fruit, said means adapted to-rotate the fruit through a complete rotation for each frictional part of an inch of advance, and said rotating knife adapted to cut into the fruit on a line perpendicular to the axis .of the fruit.
2. In a fruitslicer, the combination with a threaded shaft and a revolving knife, of a swiveled journal for said shaft, having removable threaded means adapted .to be brought into engagement with the threads of the shaft for forcing it to advance toward the knife, and an additional journal for the shaft having, a releasable element to dis engage the shaft.
3. In a fruit slicer, the combination with a threaded shaft and a revolving knife, of a swiveled journal for said shaft,having removable threaded means adapted to be brought into engagement with the threads of the shaft for forcing it to advance toward the knife, and an additional journalfor the shaft having a releasable element to disen gage the shaft, said additional journal com} prising a support, a partial journal formed thereon, and a slidable member on thesupport, having a complementary journal face.
