FRUT-G RADING MACHINE.
SPECIFICATION forming part of Letters Patent No. 5835981, clated June 8, 1897. Application filed November 20, 1896. Serial No. 612340. (No model.)
To (all whom ?it may cowcrn: to the lower end of the screen-frames, as seen Be it known thatAve, LUTHER CUNNING- in Fig. II. At the highest end is provided a HAM, of San Jos, and ROBERT GUY SMITH, grated screen 26, through which pass leaves, of Saratoga, in the county of Santa Clara, stems, dust, or other waste matter of the kind State of California, citizens of the United that may be among the fruit.

The holes therein, ter in or on the gratin g 26. through'which the fruit passes, are of varied At the forward or fecding end of the ma- 50 diameter, increasin g in size from the higher chine we provide a chain or endless elevator zoo 17, passing around the axes 21 22, driven by a pulley 22 and a band 23, connecting to a pulley 20 on the shaft 15.
To drive the machine, power is applied to the end 19 of the shaft 15 by m eans of a handcrank or otherwise, all movements being communicated from this shaft.
In Operating the machine the fruit is placed in the bin 27 and is carried up by the conveyer or elevator 17 and falls on the grated screen 26, Where the meshes are small enough to permit the passage of leaves, stems, or dirt contained in the fruit, but not of the fruit itself, which by reason of the inclination and agitation of the screen-iframe 2 passes on slowly over the perforated plates 25, most that is small enough falling through the first plate and the remainder going on to the next, and so on, down to the last screen, which has perforations large enough to pass the largest fruit.
The fruit passing through the top screenframe 2 falls on the lower screen-frame 3, where a second selection or grading takes place. The opposite screens 25 in the lower screen-frame 3 being one degree or grade less than those above, the selection or grading is repeated. So the operation being double is more rapid, complete, and a greater amount of fruit can be treated in a given time than if but one screen-frame Was employed. Beneath the screen-frame 3 are placed bins or receptacles 28, into which the graded fruit falls, also a bin 29 to catch the Waste material passing through the grating 26.
Any of the fruit which by reason of abnormal size, or is flattened by crushing, fails to pass through the screens goes 011 over them and into a receptacle provided for that purpose.
The screens 25 are preferably made of sheet metal having circular perforations, as shown in Fig. II, but may be made of woven wire or in any other manner that Will permit the fruit to pass through in proportion to its size.
The screen-frames 2 and &having coincident and opposite reciprocatiug movement longitudinally and being nearly balanced, do not produce vbration common to the reciprocating elements of such machines and can be operated Without producingvibration of the main frame or of a building in which the machine is operated.
Having thus described our invention and its objects, We claim- 1. In a fruit-grading machine, the combination of the parallel inclined screen-frames With graduated meshes or openings, the vibratin g links connecting the said frames, pivoted loosely at the center on cross-shafts, and means for imparting coincident lon gitudinal, vertical and lateral m otions to the said frames, substantially as specified.
2. In a fruit-grading machine, the combination of the parallel inclined screen-frames, the vibratinglinks connecting the said frames, pivoted at the Centers on oblon g bearings permitting of coincident longitudinal, vertical and lateral motion, and means for imparting to the said frames the said motions, substantially as specified. r
3. In a fruit-grading machine, the combination of the parallel inclined screen-frames With graduated openings, the vibratory links connecting the said frames, pivoted at the centers on oblong bearings permitting of vertical and lateral motion, cam-yokes on the lower screen-frame, cams 14, and means for rotating said cams, Whereby rapid longitudinal and lateral reciprocating motions are imparted to the said screen-frames, substantially as specified.
4. In a fruit-grading machine, the combination of the parallel inclined screen-frames with graduated openings, the vibrating links connecting the said frames, pivoted at the centers on oblong bearings permitting of vertical and lateral motion, cam-yokes ll, cams 14:, set eccentric on cross-shaft '1.5 and also inclined to the aXis of said cross-shaft, with means for rotatin g said cams, Whereby rapid longitudinal and lateral reciprocatin g motions are imparted to the said screen-frames, substantially as specified.
5. In a fruit-grading machine, the com bination of the parallel inclined screen-frames With graduated openings, Vibrating links 5 pivoted to the said framesand having vertically-oblong central bearingson shaft G permitting of vertical and lateral motion, cam- IOO yokes 11, and cams 14 set eccentric 011 crossshaft 15, and also inclined to the axis of the said shaft, driving-shaft 21, gear connections with cam-shaft 15, and endless-chain elevator 17, substantially as specified.
In a fruit-grading machine, the combination of the parallel inclined screen-frames with graduated openings, vibrating links 5 pivoted to the said frames and having vertically-oblong central bearings on shaft G pernitting of vertical and lateral motion, camyokes 11, lugs 16, cams 14; set eccentric on cross-shaft 15, and also inclined to the axis of the said shaft, driving-shaft 21, gear connections With cam shaft 15, endless-chain elevator l7, a series of graduated receptacles 28, and bin 29, all substantially as specified.
In testimony Whereof We have hereunto affixed our signatures in the presence of two witnesses.
