specification.

My invention relates to cleaning and polishing machines for oranges and other fruit; and it has for its objects to provide a simple and etficicnt construction of machine through which the fruit is fed automatically; to proinclined bars 6.

vide means whereby the fruit is rubbed or polished by the differential rotations of cooperating rolls, and to provide a cheap and efficient substitute for the polishing brushes usually employed in ueviccs of this class.

With such general Objects as the above in view the invention consists in certain features of construction hereinafter specified and particularly pointed out in the claims.

Referring to the drawings, Figure 1 is a perspective View of a machine embodying my invention. Fiz. 2 is a vertical longitudinal sectional view of the same. Fig. 3 is a transverse sectional view. Fig. 4 an end view.

Like numerals of reference indicatelike parts in all the figures of the drawings.

In the practice of my invention I employ any desired construction of framework, and have herein illustrated one simple formnvhich I will proceed to describe.

I employ opposite pairs of vertical posts 1, connecting, said pairs intermediate their ends by transverse and preferably cnstnnetal frames 2, and at their iovxer ends by tie-bars corresponding longitudinally disposed tiebars 4 serving to connect the pairs ct posts or standards 1. intermediate standa ds 5 risea't the sides of the frame and are bolted tothe tie-bars 4, and the said standards 5 project above their companions 1 and are connected to a pair of said end standards by- Arrnnged upon the inclined bars 6 is an inclined hopper 7, into which the fruit is to be introduced, and the said hopper is provided at its lower end with a discharge-chute 8 adapted to discharge directly over the cents and at one end of the machine. A cross-bar 9 sun-mounts those posts or standards 1 adjacent to the lower end of the hopper 7, and from the casting at one side of its center there projects astubshaft 10,

upon which a spur-gear 11 is located, the same having a handle 12 projecting from its outer face by which it may be manually 0p erated. V

The cross-frame 2 at that end of the machine adjacent to the gear 11 is arranged above the plane of the frame 25 at the opposite end of the machine, and each is provided with a -plurality of-journal-boxes 13, in the present instance two, one at each side of the center thereof, and said journalboxes receive the axes 14 of as many longitudinally disposed parallel polishing-rolls 15, the same being inclined contrary to the inclination of the hopper 7. One of the rolls has its shaft or axis H provided with asmall spurgear 16, while the other has its axis provided with a larger spur gear 17, but each, however, meshes with and is driven by the waster-genr 11, so that the rolls are driven in the same direction but at ditferent rates of speed. Each of these rolls is provided with a covering or polishing material 18, of sheepskin,

and between the rollsI prefer tolerate a longitudinal rest-barit), the same having its ends connected to the opposite transversely disposed end castings 2, and therefore partially closing the space between the rolls. Of course any number of rolls may he provided, their fnnctionsnnd operations being substantially the same, but I prefer to employ but two, in that I gain the best results thereby. A bottomless guide-box 2.) is arranged over the rolls and connected to the opposite transverse end-bars of the framework, the said guide box having its opposite side walls slightly elevated above the rolls, so as to give them free motion. The guide-box is inclined so as to be parallel to the rolls, and is preferably provided with aminged cover 21, which, together with the i nterior surfaces of the sides of the box, is covered with a lining 22, also of sheepskin.

This completes the construction of the machine, and the operation thereof is as follows:'lhe oranges, or other fruit, are fed into the hopper 7, and by the inclination of the same, are caused to seek the discharge 8.
