FRUIT-PARING MACHINE.

SPECIFICATION formingpart of Letters Patent No. 652,181, dated une 19, 1900. Application filed May 11, 1899 Serial No. 716,417. (No model.)

T all whom t may concern:

Be it known that I, HAVEN MARSHALL IIAFF, of Ludington, in the county of Mason which the paring may be done expeditiously and with little waste.

The invention consists in certain arrange` ments and assembling of parts of the complete machine and certain details of construction, which I shall first describe and then point out the novel features in the appended claims.

Reference is to be had to the accompanying drawings, in whichp Figure 1 is a side elevation of my machine. Fig. 2 is a plan view thereof. Fig. 3isa horizontal section on line 3 3 of Fig. 1.

Y My improved parer is mounted on a suitable framework and consists of a cutter-head 21, secured upon the cranked arm 22 of the vertical shaft 23, mounted to rotate in suitable bearings in the' bed-,plate andA base of the framework. The said cutter-head 21 is provided with a horizontal spindle 24, mounted in u prights and rotatable about its longitudinal axis. A paring-disk 25 (shown in detail in Fig. 7) is fixed on one end of the spindle, and on the other end of said spindle is keyed a pulley 26, connected by abelt with a pulley 27 on one end of a short horizont-al shaft 2S, held in depending arms secured to the cranked arm 22, the opposite end of said latter shaft having a bevel-pinion 29 gearing with a bevel-pinion 30 on the upper end of a hollow shaft 31, surrounding the shaft 23, but movable independently thereof.. The outer shaft 31 is rotated by a pulley-and-belt p connection with a large band-wheel 32,mount `ed on a shaft journaled in bearings on up-V rights of the framework, this wheel in turn having connected with it a gear-wheel 32, which meshes with a second though larger gear-wheel 32" on a shaft 33, which shaft is the main shaft of the entire machine and may be operated by an engine orby any other suit-able power. On the shaft 33 at one side of the large gear-wheel 32b is fixed a frictiondisk 34, with which a horizontal and longitudinally-slidable shaft 35 engages by means of a suitable leather 'or other friction drum 36 on its adjacent end, and the latter shaft extends longitudinally of the framework of the machine some distance beyond the vertical shafts 31 and 23. Between its ends the shaft 35 is provided with a wide pinion 37, arranged to mesh with a gear-wheel 38, mounted between short posts on the base of the framework, the shaft of said gear-wheel carrying a crank 39, connected by a wrist-pin with a pitman 40, which is connected with a rack 41, meshing with a pinion 42, secured on the lower end of the cutter-head shaft 23. A flanged pulley 43 is splined on the shaft 35 and is connected by av belt 4with a second flanged pulley 44, mounted on a tiltable frame 45. Adjacent to the pulley 44 and preferably integral therewith is a sprocket-wheel 46, connected by chain with a sprocket-wheel 47 on the fruit-carrier 48, consisting of arotatable spindle 49 and a series of prongs 50 or 51, held thereon bya collar 52, as best shown IOD p in Fig. 9, the prongs 50 being better adapted 35, which in turn moves the gear-wheel 3S comparatively slowly. The pitman is thereby caused to move the rack to turn shaft 23, carrying the cutter-head, which as the pitman reciprocatcs will move the paring-disk half-way around the peach and then back again. All this time the peach has been rotating by means of the rotatable carrier and its pnlley-and-belt connection with the shaft 35, and in order to vary the rate of movement of the peach I mount a throw-off lever 53 in the base of the framework, the said lever extending upwardly between two collars on the shaft 35, whereby to move the drum en the latter into closer or wider engagement with the friction-disk. In order to stop the shaft 35 altogether, the friction-disk is formed with a central recess 54, into which the drum may be carried, so as to be entirely free from contact with the said disk. During this operation of paring it is expedient that the thickness of the paring be carefully adjusted, and to this end I mount a guard 55 (best seen in detail in Fig. 6) on the bed-plate of the cutter-head. The guard is placed in frontof the paring-disk, and through its face the paring-disk comes in contact with the fruit. It is of such shape that where the center of the paring-disk comes against it from the rear the guard is bulged slightly inward, so that no matter if the guard be considerably changed in position the edge of the disk will not come into contact with the metal face of the guard. At its lower end the guard is formed with a curved foot 56, formed with an elongated slot in which works a clamp, whereby the guard is held in a correspondingly-curved recess 56a in the bedplate of the cutter-head. By this construction when the foot is moved forward the upper portion of the guard will be thrown back and the parings will be thicker. If the peaches happen to be very soft, a paring-disk 57 (see Fig. 7) may be used, the said disk having a wavy edge, and when peaches are more than usually soft a drag-knife 58 (shown in Fig. 10) may be used. Referring to Figs. 10, 11, and 12, it will be seen that this drag-knife is operated and supported by the same devices described above in connection with the paring-disks. To this end the upper portion of the cutter-head is slipped somewhat to one side, the paring-disk removed, an eccentric crank-pin 24 is secured in the end of the spindle 24, a guard of the form shown at 55 is secured to the cutter-head, the said guard being formed with an undercut slot 55b and waste-slot 55C, and the crank-pin works in an elongated slot in the knife. It is obvious, then, that when the spindle 24 is rotated it will reciprocate the drag-knife 5S. After the peaches have been pared by one of the disks or knife the operator, whose hand grasps a loose handle 59 on the fruit-carrying spindle, throws the frame 45 to the right, as shown in dotted lines in Fig. 15, which causes the upper pulley 44 to turn down and the belt to become slack, thereby stopping the fruit-carrying spindle. The fruit is then unloaded on the fork GO. As is usually the case with peaches, the fruit may have one or more depressions in its surface which the paringdisks will be unable to reach. In such cases the operator holds the peach in his hand against a very small disk 61 on an upright permanently located on `the bed of the framework, the said disk being actuated from the shaft 31 by means of a pulley 61a on the shaft 31, connected by a belt Glb with a pulley 61c on the shaft of the attachment, and the said shaft extends upward and terminates in a small pinion G1, which meshes in a circle of cogs 61e on the back of the disk 61, as best shown in Fig. 17, or when the valley of the peach is left untouched by the main parer I preferably employ two disks 62, set at an angle of about forty-five degrees with respect to each other, said disks being also actuated from the shaft 31 by a pulley G2a on said shaft, connected by the band 62b with a pulley (32c on one of the shafts of this latter attachment, as shown in Figs. 8 and 18, the other shaft of the said attachment being connected to the first named by cog-wheels, as shown. The guards employed to regulate the size of parings and to protect the operators hand in these instances are of the form shown in Figs. 16 to 20, inclusive.

While I have described my paring-machine in connection with peaches, it is manifest that it is equally as applicable to apples or other fruit and vegetables, such as potatoes or the like.

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