Original No. 1,246,463, dated November 13, 1917, Serial No. 80,991, filed February 28, 1916. Application (or reissue filed September 13, 1921.

To all whom it may concern:

Be it known that I, WILLIAM K. PRI E, a citizen of theUnited States, and a resident of Selah, in the county of Yakima and State of Washington, have invented a new and useful Fruit-Sizing Machine, of which the following is a specification.

My invention relates to what is commonly termed a fruit-sizing machine, although its a plication may be extended to the sorting 0? other objects to which it may be found applicable.

The object of my invention is to produce a device for sizing fruit by weight and to do this more accurately than has been done by previous designs; to simplify and reduce the number of parts required; and to reduce the space required for a given output of fruit when separatedinto two or more grades and the required number of sizes for each grade.

In the accompanying drawing, Figure 1 is a lan View; Fig. 2 is a vertical elevation, part y in section; Fig. 3 is a detail of the cam mechanism; and Fig. 4' is an enlarged detail.

In the drawing, the bins 1 to 16 are arranged. radially to form a circular structure and are adapted to receive the different grades of apples or other fruit to be sized.

The sorting-table 17 is provided for receiving the fruit, with the outlet 17 a through which the apples are fed to the conveyers or

elevators

18 and 19, said elevators being separated by the partitionl'l ..The elevators comprise suitable belts with the wings 18 thereon adapted to engage the apples andcarry them to the top of the elevator. are discharged .into the

cups

20 and 21. e sup orting-frame 23 has the shaft 22 journale therein, said shaft being nonrotary and held in positionby thelpin 25f The gear 26 is mounted to rotate on the shaft 22, said gear having a bearing in the cup 27. The casting 28 connected to the gear 26 has a turning fit on the shaft 22, and the extension 29 is also adaptedto turn on the shaft 22, forming pa'rtof the casting 28.

Serial No. 500,421.

The cup-arms 34 have the knife-edges 34 at their lnner ends, which rest in grooves 35 in the lugs 32. The casting 29 has sixteen arms 36, Wh1ch have forked ends 37 through wh ch pass the cup-arms 34. Pins 38 located in the forked ends 37 of the arms 36 prevent the arms 34 from dropping entirely out of place. Thecup-arm 34 is provided with the vertical arm 39, which passes through the slot 40 in the arm 36. The arm 39 carries a bolt 41, which is adjustable in said arm, and the nner end of said bolt rests against a cam 42, which is secured to the casting 30. The vcups are numbered respectively 20 and 21, there be ng eight of each, and all the bolts 41, wh1 ch are attached to arms of cup 20, bear against cam 42, while all bolts 41, wh ch are attached to arms of cup 21, bear agalnst cam 43.

The arms 36 each supportv a tensionsprlng 44, which are connected to an adustable bolt carried by the cup-arms 34.

The cups 20. and 21 are made of canvas or other suitable material, which is supported by the annular metal rims 46. The metal I'1II1S 46 are Welded or.otherwise secured to bars 47, which extend through the hollow portions-48 of the cup-arms 34, said bars 47'being provided with arms 48, which carry the

fingers

49 and 50. Springs 51 are coiled around the bars 47, one end of said sprlng engaging the arm 48, and the other end of the spring engaging, the vertical portion 34" of the cup-arm 34. In this manner the spr1ng 51 tends to hold the cup in re-. ceiving-posltion, as indicated in Figs. 2 and .4. I

The finger normally rests against the vertical portion 3430f the cup-arm 34.

The bevel-gear 52,.engages the gear 26 and rotates the castings 28 and 29 and the attachedparts-lugs 32 and the arms 36. The bevelgear 54 on theshaft 53 drives a gear 55 onv the shaft 55. A sprocket-wheel 56 on the shaft 55 drives the sprocket-chain 57, which drives the sprocket-wheel 58 on the shaft 59, which carries the elevator belts, which are provided with wing 18 for elevating the fruit, one at a time, for

55 33 throng which pass sixtee i cup-arms 34.

each wing. The motor for driving the machine is belted to the pulley 61 on the shaft 53. The 1. gear and sprocket-wheel ratios are made to drive the cups so they willpass the elevator at the rate of 180 per minute. Each The casting 30 is fixed to the shaft 22 by the in 31. I e casting 28 is provided with'rad1allyextending lugs 32 corresponding to the numberof on s, and said 111 have forked ends elevator belt drops a piece of fruit into a cup at the rate of 90 perminute; the belt 18 drops fruit into cups 20, and the belt 19 drops fruit into cups 21. The machine is so timed that the cups pass the elevator at Ehe right moment to catch the fruit as it alls.

The cams 42 and 43 are largest at a point opposite the elevator, and they decrease in radius as the bolts 41 move around them from the elevator thus allowing the cuparms to rise and decrease the tension on spring 44. The cam 42 begin to decrease in radius just opposite bin 1, and it is reduced to its smallest radius opposite bin 11. The cam 43 begins to decrease in radius opposite bin 6, and is reduced to its smallest radius opposite bin 16. After passing bin 16 both cams rapidly increase in radius un til they reach the position for receiving the fruit in cups. V

The casting 30' carries sixteen arms 62,

each arm carrying a tripping-arm 63, which i adjustable vertically. The tripping-arms 68 carry both. lugs 64 and 65. The tripping-arms which come opposite bins 1 to 5 carry the upper lugs only; the trippingarms which come oppositebins 6 to 11 carry both

lugs

64 and 65; and the tripping-arms which come opposite bins12 to 16 carry only the lower lugs 64.

In operation, the apples to be sized are dumped on to the sorting-table 17, and are fed

t elevators

18 and 19. The apples passing up the belt 18 drop into the cups 20, while the belt 19 drops the apples into the cups 21. As stated above, all bolts '41 which are attached to arms of cup 20, bear against cam 42, and all bolts 41, which are attached to arms of cup 21, bear against cam 43. The springs 44 are adjusted to hold the bolts 41 in contact with the cams 42 and 43, but with no pressure when an apple weighing, for instance, one pound, is in the cup when the cup is leaving the elevator. The springs are further adjusted sea 2%- oz. apple will cause the bolts 41, which are connected to cups 20 to separate from the cam'42 at the bin 11, and Wlll cause the bolts 41, which are connected to cups 21 to separate from the cams 43 at the bin 16. The radius of the cam 42 is suiiiciently reduced at the bin 1 so the bolt 41 will separate from the cam 42 when the cup is carrying a one-pound apple; and the radius of the cam 43 is, sufiiciently reduced at bin 6 so the bolt 41 will separate from the cam 43 when the cup is carrying a .onepound apple. Apples of intermediate weights will cause a separation of bolts 41 from cams 42 and 43 at bins between 1 and 11 and between 6 and 16 in proportion to their weight.

If there are no apples in the cups, the cups move around the circle of bins from the elevator, the springs 44 holding the bolts 41 in contact with the cam 42 all the way around, which causes the cups to gradually rise until cups 20 pass bins 11 and cups 21 pass bin 16, when they fall until they reach the position for receiving the fruit.

Thelugs 65 are located just high enough to miss the fingers 49 of the cups 20 when there are no apples in the cups. The lugs 65 are located successively higher so they just miss the finger 49 as said fingers are gradually lifted up by the action of the cam 42, said lugs or trips varying in position in the same ratio as the curve of the cam varies. The lugs 64 are arranged successively higher so as to just miss the fingers 49 of the cups 21 when there are no apples in these cups. When an apple drops in a cup the strain on the spring 44 becomes greater, and at some point in the movement of the cup over the bins, the spring 44 will be unable to hold the bolt 41 in contact with the cam 43, which causes the finger 49 to top rising, and said finger then catches against the lugs 64, which tips the cup over and drops the apple into the bin. The spring 51 acting on the bar 47 turns the cup to position for receiving another apple. The point where the bolts will leave the cam 42 for cups 2 0 depends upon the weight of the apple after the springs have been adjusted to drop a pound apple in bin l and a 21} oz. apple in bin 11; and this is also the case with bolts 41, cam 43, and cups 2 1, which drop a pound apple in bin 6and a 2-}-oz. apple in bin 16.

The sizes of apples that will fall in. each bin are indicated by the circles in these bins, Fig. 1. The extra fancy apples are in bins 1 to 11, and the fancy apples are in bins 6 to 16; and both the extra fancy and fancy apples are in bins 6 to 11,'but they difier in size so that the packers are able to pack them in separate boxes and they mark the boxes accordingly.

The cams act as steadying members to prevent vibration of the scale-beams or cuparm until the accurate weight is determinedat which instant the fruit or other article i dropped into the proper receiving-bin.
