BEISSUED Application filed March 29, 1922. Serial No. 547,745.

To all who'mit may concern:

Be it known that we, MCCLELLAN A.

KUHN and FRED STEBLER, citizens of the United States, residing, the said KUHN at Porterville, in the county of Tulare and State of California, and the said STEBLER at Riverside, in the county of Riverside, State of California, have invented certain new and useful Improvements in Packing-Service 0 Apparatus, of which the following is a specification.

The hereinafter described invention is designed for use in connection with the fruit packing industry, and is utilized for bringing boxes of unsorted fruit to sorting stations where they are removed by operators known as sorters for the sorting of the fruit contained therein; the construction of the apparatus being such that a line of boxes containing unsorted fruit is constantly maintained at the sorting stations, the various sorting stations being automatically maintained filled on the removal of one or more boxes from the line of sorting stations, the feed means for'the boxes being intermittently thrown into operative relation the moment a box of unsorted fruit is removed from a sorting station for sorting purposes. In other words, the removal of an unsorted box of fruit throws into action the means for allowing another box to take its place.

The boxes as brought in from the orchards contain fruit indiscriminately mixed as to sizes and grades, and it is required that the 35 fruit be sorted to remove the imperfect and undersized specimens prior to packing for shipment. I

The principal object of our invention is to provide-an apparatus by the use of which the sorting and packing of the commodities will be greatly facilitated, in that the boxes of fruit to be sorted are automatically fed to the individual receiving. stations, as fast as boxes are removed therefrom by the packers .45 for sorting purposes.

Our invention consists in an apparatus employing preferably a straight conveyor of considerable length, over which the unsorted boxes are fed from one end, with; stations 50 provided for the packers on each side throughout its length, whereby considerable labor and time is saved by eliminating the necessity for the unsorted box handlershaving to keep watch over the whole length of the device and place the boxes directly at the polnts Where the individual packers are located.

Another object of the inventionis to provlde means for automatically regulating the travel of the unsorted boxes along the device; that is, if the conveyor for the entire length of the machine is filled, the movement of the boxes will automatically discontinue, while as soon as any one box of the series 'of boxes is removed to be sorted, the travel or feeding of the boxes is automatically resumed, so as to fill the space rendered vacant by the removal of the box; a further object being to arrange, in connection-with the various sorting and packing stations, means for conveying the culls and other fruit not suitable for packing to a predetermined point from all the packing stations, and separate means for returning the initial boxes after being emptied, to another predetermined point, with but very little work and effort on the part of the packers being necessary, and to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purposes for which it is designed.

In order to comprehend the invention reference should be had to the accompanying sheets of drawings illustrative of a preferred embodiment of an apparatus for the practical carrying out of the invention, and wherein Figure 1 is a broken top plan view of a portion of an apparatus for carrying out the igvention, taken adjacent the rear end there- 0 Figure 2 is a cross sectional view, taken on the line 2-2 of Fig. 1.

Figure 16 is a similar view of the rearmost station and the box-receiving skids therebeyond, showing an electrical contact mechanism arranged between the skids for the purpose hereinafter explained.

In carrying out of our invention, we employ a structure which comprises a suitable and substantial supporting frame, consisting essentially of longitudinal, spaced and parallel beams 1, connected at intervals by cross ties or beams 2, and supported from the floor by standards 3. These members, as above stated, form the essentials of a supporting frame, such bracing being used in addition as will make a structure rigid and substantial enough to stand up under the fairly heavy loads and work to which it is subjected.

Positioned between the beams 1 at spaced intervals throughout the length of the apparatus are provided box receiving platforms or stations 4, each one being pivotally mounted at one end to the beams as at 5, Figs. 5, 6 and 7 of the drawings, at the end of the station opposite to the forward end of the line of stations, the opposite ends of the platforms being free .for limited vertical movement, and each platform bein of a size to receive a box of unsorte fruit thereon.

Normally these platforms 4 are held on a level and horizontal plane by means of coun terweights 6, Figs. 5 and 6 of the drawings,- mounted on. arms 7 which are pivoted intermediate their ends to the transverse beams 2 as at 8, while the ends of said arms opposite to the weights thereon are pivotally linked as at'9 to the free ends of the platforms, it being understood that the platforms 4 are mounted independent of each other. The platforms 4 are prevented from raising above a horizontal level by means of brackets 10 fixed thereon adjacent their free ends, (see Fig. 7 which project under the longitudinal beams 1, one of each pair of brackets 10 carrying a contact 11 adapted to bear against a similar contact 12 fixed on one of the lonitudinal beams 1, when the platform is in its raised position, the purpose of these contacts and the parts co-operating therewith being set forth hereinafter.

J ournaled onto the beams 1 at spaced intervals and extending between all the platforms are rollers 13, which are arranged to be rotated simultaneously as through the medium of caring 14 driven from a common shaft 15, igs. 1, 2, 3 and 5 of the drawings.

The rollers 13 rotate in a counter clockwise direction when looking from the front to the rear end of the line of box receiving stations, so as to feed boxes onto the various platforms and move themalong from the forward toward the rear end of the line of stations. The upper faces of these rollers are above the top of the platforms 4, which have a plurality of anti-friction box-supporting elements extending longitudinally thereon, and situated in a plane slightly below the top of the rollers 13.

These anti-friction members 16 are preferably in the form of ball-casters 16, Figs. 1, 2, 3, 5 and 6 of the drawings, this type being very substantial, and allowing for easy movement of a box both longitudinally of the box supporting platforms 4 and transversely thereof, when it is desired to pull a box from a platform sideways. However, any suitable forms of anti-friction supporting means may be used, as for instance the type shown in Fig. 8 of the drawings, which consists of endless chains 17 extending longitudinally of the platforms in spaced relation and mounted on sprockets 18 journalled in the platforms. Projecting outwardly of and mounted on the chains are rollers 19 whose axes extend longitudinally of the platforms 4 and which sustain the weight of the boxed supplies. When a box is moved. onto the platform 4 impelled by the adjacent roller, the chain moves lengthwise thereof,

the sprockets rotating, while when a box is to be removed-by pulling the same sideways, the rollers revolve while the chains remain stationary.

Certain of the platforms 4, preferably every fifth one-has adjacent its pivoted end a contact 20, normally engaged by a contact 21 mounted on a bar 22 hinged to the platform 4, as shown at 23 in Fig. 15.

Fixed to or formed with the bar 22 is an arm 24, which projects above the hinge member and toward and over the adjacent roller.

13, Figs. 1 and 15 of the drawings, As far as said roller, the arm is below the level of the roller and casters, but beyond that point the arm is curved upwardly as at 25 so as to be above the level of the roller 13, and to be then engaged by the bottom edge of a box moving toward said roller. The curved portion of the arm 24 will then be depressed, the box passing thereover, and said portion will then rest in a depression 26 cut circumferentially in the roller 13; Since the arm 24 is rigid with the bar 22, the latter will then be turned on its hinge, separating the con- I tacts 20 and 21 for the purpose as will appear. The contacts are normally held engaged, and restored to that position by the tension of the adjustable spring means'27 when the load is taken off the member 25.

There are no transversely disposed rollers 13 situated beyond the rearmost platform 4 of the series of platforms but skids 28 su fie contacts, or a high and low voltage system "any boxes in the event that the system for any reason, due to a broken box or otherwise, should fail to function and halt the travel of the boxes at the last station, as hereinafter described.

Mounted between the skids 28 (see Figs. 1 and 16) is a pivoted arm 29, the upper end of which projects above the said skids, while the lower end thereof has a contact 30 norinally held in engagement with a fixed contact 31 by spring means 32, the breaking of these contacts by a box engaging and depressing the upper end of the arm 29 positively stopping the travel of the boxes. as will be seen.

The boxes are fed onto the line of stations or platforms in single file and from the forward end of the system by means of an elevator 33 (see Fig. 3) which preferably con- Figs. 3 and 9), an endless chain 37 around said sprocket driving a jackshaft 38,.from which the upper conveyer shaft 34 is di- 'rectl driven. The jackshaft here shown is mere y used for convenience of arrangement, and can be omitted if desired.

The shaft 36 is adapted to be driven from loosely on the shaft 36, with which sprocket wheel one member 41 of a clutch is formed or fixed thereon. The co-operating member 42 of this clutch is slidably splined onto the shaft 36. The clutch operating arm 43, in the t pe of mechanism shown in Fig. 9, has a weight 44on its upper end adapted to be raised .by an electrically energized magnet 45, the parts being so arranged that when the magnet is energized the clutch is thrown in and the shaft 36 will turn, driving the elevator 33.

The roller-drive shaft 15 is driven continuously from the shaft 39 by suitable gear and chain means as shown at 46 and 47 respectively, Fig. 3 of the drawings.

It will be understood that while we have specifically designated various forms of drive for the transmission mechanisms, any other sultable devices for transmitting the power to the Various driven members and may be used. Since these are matters of electrical installation and adaptation, we have shown and will describe only the first named type.

The main power lines 48 lead directly to a motor 49 through wires 50, a switch 51 being interposed between the wires 48 and 50, this switch being connected with a novoltage release structure conventionally illustrated at 52. For this purpose, we prefer to employ a Trumbull 3-pole switch, with no voltage release attachment. 'From one of the wires 50 a line 53 leads to the rearmost station-contact 12, while branches 54 lead from said wire to the other similar contacts.

Between the first station and the main line 50, a switch 55 is interposed, normally open.

From the other one of the wires 50 a wire 56 leads to the magnet 45, from the other pole of which a wire 57 leads to the rearmost movable station contact 11, there being branches 58' from said wire to all the other similar contacts, so that all the sta-' tion contacts are wired in series.

A wire 59 leads from the wire 53 between the switch 55 and the feed wire 50 to the first contact 21 of the fifth station and roller structure, Fig. 15 of the drawings, another wire 60 leads from the adjacent contact 20 in an unbroken line.

to the next contact '21, and so on to the end of the line of stations where the final wire 61 leads from the last contact 20 to the wire 53 adjacent thereto.

It will thus be seen from the foregoing arrangement that, owing to the normally open switch in the station-contact wiring, a. circuit therethrough will only be closed when the current can pass through the wires 61, 60 and 59, the latter of which bridges the switchap.

It will a 0 be borne in mind that it is only when this circuit is closed that the magnet will be energized, holding the clutch 41- 12 thrown in and the box delivery elevator running.

In operation, assuming the motor to be running, and the box receivlng stations all empty. This causes the contacts 1112 to be made, causing the aforementioned clutch to be thrown in and the elevator to be operated.

The boxed supplies are then fed onto the elevator which carries them onto the line of stations, the driven rollers (which it will be remembered are not affected by any inoperation of the elevator but only of the motor) which impels them along the line of stations. As each box rests on a statlon, the weight becomes greater than the counterbalancing effect of the weights 6, and the station is depressed at its free end, breaking the contacts. It will be noted, however, that owing to the series form of wirlng used, the contacts at all the stations must be broken before the circuit will be broken through the clutch-magnet and the elevator discontinued, while on the other hand, the engagement of any one pair of such contacts, had when a box is removed from a station, is Sufficient to close the circuit and set the elevator in operation.

Now the object of the additional contacts at the fifth stations and rollers is this With the elevator running and boxes being fed continuously onto the line of boxre-' ceiving stations, the boxes naturally abut one against the other and are pushed along Since each receiving station is approximately the length of a box, the extra and unavoidable space occupied by the rollers between the stations does not rightly locate a box directly above each station under these conditions, as will be evident, It is to permit the boxes tobe separated at intervals so as to allow them to rest squarely on a station that these fifth station contacts are employed.

When a box abuts against an arm 25, with the continued movement thereof the arm is depressed, at once breaking the contacts 20 and 21, which breaks the circuit through the magnet, causing the elevator to stop, regardless of the filled or unfilled condition of all the stations. The rollers howare on the line of stations and resting on the rollers to be moved to the rear until they individually rest on the platforms, this inoperativeness of the elevator continuing as long as it takes the length of a box to pass over the roller having thearm 25 projecting thereover. As soon as the arm is released and the contacts re-made, the elevator will again start, provided all of the stations are not filled, which, as previously explained, automatically causes the circuit to be broken and the elevator to be discontinned.

Now regarding the contacts 30 and 31, at the rear end of the line of stations, these are connected to the no-voltage release structure 52 and to the wires 50 by means-of wires 62, the contacts 30 and 31 being normally closed.

If the boxes should for any reason pass beyond the last station and on to the skids, the arm 39 will be depressed, breaking the contacts and breaking the no-voltage release circuit, causing the main switch 51 to be opened, stopping the motor, which not only stops the elevator but the rollers 13 as wel It will be evident then that the only attention as to the feeding of supplies onto the stations is to keep the elevator loaded, since whenever a box is removed from any station of the series of stations, the feeding is instantly resumed to fill the vacancy.

This electrically operated system is the one we prefer. However, referring to Fig. 10, a mechanically actuated clutch throwing mechanism may be used. In this structure, there is employed a longitudinal shaft 63 extending throughout the entire length of all the stations, and turnably mounted on the framework of the device. To one end of this shaft operative connections 64: are made with the clutch member 42*, which is normally held thrown out by spring means 65 or otherwise. Projecting outwardly from the shaft 63 under the free ends of all the stations 4 are arms 66 which when the clutch is thrown in are held raised against the pull of the spring 65 by means of lugs or pins 67 projecting under the arms 66 and fixed on the lower ends of hangers 68 fixed onto the free ends of the platforms and depending therefrom. Now if the stations are all filled, the lugs 67 will be moved down and away from the arms 66, allowing the spring to act and throw out the clutch. The raising of any one lug, however, when a platform is emptied, is sufficient to raise I employ a longitudinal shaft 69 under the line of stations. Figs. 12 and 13.01 the drawin which shaft is movable longitudinally. Saud shaft is operatively'fconneeted with the clutch member 42 as by a forked crank 70 normally held to throw the clutch out by spring means 71. A foot-lever 71, Fig. 11 of the drawings, is provided for each .operator, adapted when depressed to engage and 'raise a wedge-shaped member 72, the wedge face of which engages a pin 73 projecting from the shaft 69, so that when an lever is depressed, the member 72 is raise causing the shaft to be moved endwise. for throwing in the clutch, this operation being done when a packer removes a box from a station, and keeping the lever down until its place is filled.

Referring to Figs. 1, 2 and 4, on each side of the structure and downwardlyinclined therefrom between the stations are transversely disposed beams 74 supported at their outer ends by posts 3 and on which, adjacent the upper, ends thereof, are bearing blocks 75 in which are removably mounted rollers 76, whose upper faces are preferably about at the level of the station-casters 16. At the lower end of the beams 74 are provided racks 77 which extend the full length of the line of stations, any box drawn from a station being moved over the adjacent roller 76 until the outer end rests in the rack, while the opposite end will rest on the said roller, as shown in dotted outline in Fig. 2. Below the beams 74L, and positioned between the rollers 76 and racks 77 is a flooring 7 8,.on which travels an endless conveyer preferably comprising spaced and endless chains 79, mounted on sprocket wheels 80 at both ends of the line of stations, one set of said sprocket wheels being preferably mounted on the shaft 39, to be driven thereby (see Fig. 3).

Beyond one end of the endless conveyer is located a downwardly inclined skid board 81 on each side of the elevator 33, and which said board leads down to the floor, so as to deposit the empty boxes'carried by the endlessconveyer within reach of the field workers.

The boxes after being Withdrawn laterally from the stations by the sorters are positioned and supported as above stated while the fruit is being removed therefrom and sorted and packed. The operator then deposits the empty box onto the conveyer just described, by raising up the end held by the rack, and drawing it toward him or away from the stations sufficiently for it to' clear the roller 76. That end will then drop onto the conveyer, and he will then release the other end simultaneously. The boxes are prevented from missing the conveyer when so dropped by reason of guard boards 82 extending above the flooring 78 and fixed to the posts 3 and 3 lengthwise of the device.

Beyond the beams 74 and arranged in staggered alinement on each side of the station structure are the assorting andpacking tables 83, Figs. 1 and 2 of the drawings, which support the boxes; to be packed; The floors of these tables are below the side walls thereof and in the form of inclined chutes 84', all thoseon each-side leadin down to a trough 85 extending longitu inally of the device and ositioned between the empty boxconveyer and the posts 3. The purposeof these chutes and troughs is to receive the culls etc. removed from the box,

of unsorted fruit being handled by the packers.

The culls, when delivered to a trough, are moved along to a predetermined end thereof by means of a suitable conveyer here represented as an endless chain 86 mounted on sprockets 87, one of which is driven from the shaft 39 (see Fig. 3). Secured to the chain at intervals and extending transversely thereof and for the full Width of the trough are cleats or scrapers 88 arranged to straddle the chain and rest on the floor of the chute, so as to sweep the culls along with the movement of the chain.

From the foregoing it will be noted that our' apparatus comprising a plurality of alined sorting stations, independently dis posed box receiving means associated with. said stations, intermittently actuated mechanism for feeding boxes filled with unsorted fruit, onto said receiving means, and devices for automatically controlling the action of the box feeding mechanism in accordance as to whetheror not the series of receiving means are supplied with boxes of fruit to be sorted.

In the present case the apparatus is illustrated as a double sorter, that is provision is made for sorters to operate from either side of the box runway, but such is merely a preferred construction of the apparatus for obtaining greater capacity 'as to operators and equally so to occupy -less space than otherwise would be required to accommodate a corresponding number of operators or sorters.

While this specification sets forth in detail the present and preferred construction of the device, still in practice such deviations from such detail may beresorted to as do not form a departure from the spirit of the invention, as defined by the appended claims.
