4 Sheets-Sheet 4 Filed Dec. 31, 1946 Inventor William E Altenpohl 2mm and Z5? Patented May 31, 1949 UNITED STATES ATENT OFFICE AUTOMATIC WEIGHING AND SORTING MACHINE 2 Claims.

My invention relates to improvements in automatic weighing and sorting machines for poultry, especially, although not necessarily.

The primary object of the invention is to provide an efficient, simply constructed machine adapted for substantially continuous operation to weigh and sort by weight chickens, turkeys, ducks, and other poultry for shipment, cold storage, or other purposes.

Another object is to provide a machine of the character and for the purposes set forth which is accurate, comparatively inexpensive to manufacture, install and operate, and which will not readily get out of order as the result of prolonged use.

Other and subordinate objects, also comprehended by my invention, together with the precise nature of my improvements, and the manifold advantages thereof will be readily understood when the succeeding description and claims are read with reference to the drawings accompanying and forming part of this specification.

In said drawings:

Figure 1 is a view in plan, partly broken away, of my improved automatic weighing and sorting machine in a preferred embodiment thereof;

Figure 2 is a view in side elevation looking at the weighing and sorting side of the machine;

Figure 3 is a View in vertical transverse section taken on the line 3-3 of Figure 1;

Figure 4 is a fragmentary view in vertical transverse section taken on the line 4-4 of Figure 2 and drawn to a larger scale;

Figure 5 is a fragmentary View in side elevation illustrating one of the carriages with the trolley wheels positioned on one of the track bridging sections;

Figure 6 is a View in vertical section taken on the line 65 of Figure 4.

Referring now to the drawings by numerals, my improved automatic weighing and sorting machine, in the illustrated, preferred embodiment thereof, comprises a frame structure including a horizontal, endless top conveyor supporting rail '5 of elliptical form, generally, and which may be of any suitable length and width and is preferably of angle bar construction. Transverse angle bars 3 brace the conveyor supporting rail 1 adjacent the ends thereof, and similar transverse bars 9 intermediate said bars 8, the bars 8 and 9 being equidistantly spaced apart longitudinally of said rail 1 for a purpose presently seen. Longitudinal, central brace bars l0 extend between the end bars 8 and the ends of said rail 7.

Pairs of legs, preferably angle bars, support the transverse bars 8, 9 and are spaced apart equidistantly upon opposite sides of the longitudinal center of said rail '5, with the upper ends thereof suitably connected to said bars 8, 9 in inwardly offset relation to the sides of said rail 1 so that said rail at its sides overhangs said legs II, as well as at its ends, for a purpose presently clear.

A track supporting, endless, rail bar 12 of the same shape as said rail 1, but relatively smaller, is suitably fixed in horizontal position to the legs l i below said rail and in centered relation thereto. Lateral bracket arms 13 outstanding from said rail bar 52 carry on the outer ends thereof a bevelled edge, rigid track it of the same shape as said rail 1 and which is vertically aligned with said rail and provided on one side of the machine, hereinafter referred to as the weighing and sorting side, with gaps l5 therein intermediate the legs H on the designated side of the machine.

An endless, brace rail E6 of the same shape as said rail 1 and said bar 12, and of substantially the same size as said bar is suitably fixed in horizontal position to the legs II intermediate said bar and the lower ends of the legs. A pair of end legs ii at the ends of said bar 12 and said rail l5 depend from the brace bars l6 and additionally support the rails 7, l6 and said bar [2. The described brace rail 18, together with the pairs of legs N, form transverse stalls 18 open on both sides of the machine and each centered below one of the described gaps I5 for a purpose presently explained.

Bar-like track-bridging sections 19 of bevel edge form, are fitted endwise in the gaps 15 for Vertical movement in said gaps, said sections I9 forming front cross ends on transverse scale beams 20 extending from the weighing and sorting side of the machine toward the other side thereof in between pairs of the legs 1 l and in the transverse centers of the gaps It. The scale beams 20 are mounted adjacent said sections is to rock vertically in upstanding, bifurcated bearing brackets 21 co-planar with said beams and suitably fixed to the rail bar 12. The scale beams 20 are provided with knife-edge bearing studs, as at 22, rocking on the upper ends of said bearing brackets 2|. The usual graduations, as at 23, indicating pounds and fractions thereof are provided on the scale beams 20 and the usual counterweights 24. Suitably arranged channel stops 25 in which the rear ends of the scale beams 20 play, limit vertical swinging of said beams.

A plurality of trolley carriages 26 are provided.- to run on the track M and the track-bridging sections i9. Each carriage 26 comprises, preferably, a substantially rectangular, forked, yoke 27 with depending end arms 28, and a top, relatively narrower hanger plate 29 upstanding in the vertical center of the yoke 2'1 and connected thereto by a lateral ledge 38 extending from the top of said yoke. The hanger plate 29 is formed with a top wheel housing 32 of inverted channel shape. A pair of grooved trolley wheels 32 are suitably mounted in the wheel housing 3[ to roll along the track i4 and the track-bridging sections l9. The trolley wheels 32 are spaced apart so as to both ride on said sections i9 at the same time.

As best shown in Figure 4, the trolley wheels 32 suspend the yokes 271 of thecarriages 2% in vertical position to travel endwise beneath .the track M and the track-bridging sections i9 above the stalls H3. The yoke, 27 of each carriage 26 supports thereon a trough-like shelf 33 pivotally mounted, as area, between the lower ends of crea s 23 toswing forwardly and rearwardly into dumping and normal positions, respectively,

about an axis parallel to the direction of travel of the carriage 2%, the arrangement being such that in the normal position of the shelf 33, the open side thereof faces forwardly of the weighing and sorting side of the machine, and said shelf is normally overbalanced to swing, under the influence of gravity, downwardly and forwardly into inverted dumping position, open side lowermost.

' Co-acting devices are provided on each carriage '26 and shelf 33 for releasably locking the shelf 33 in normal position, said devices comprising a rigid dog 35 extending laterally from the shelf 33 through the, yoke 21, an upstanding trip pin 36' vertically sliolable in a lug ti on the yoke 21 into dog locking and releasing positions, respectiyely, and a horizontal pin raising arm 33 to which the, upper end of said pin 36 is connected by a pin and slot 33, 40, said arm having a front end pivotedf as at M, to a bifurcated post 42 upstanding from the ledge 3d of the yoke 27, and said arm having a free end 43 adapted to be raisedto swing the arm upwardly. Adjustable screws 45 are extended upwardly through the bases ofthe bearing brackets 52!, opposite the transverse centers of the track-bridging sections [9, and are adapted to be engaged b the free ends 4 3 of the pin raising arms 38 when the carriages 26 are lowered, in a manner to be described.

" endless conveyor chain 55 extends around the conveyor supporting rail 'i' and is trained around sprocket wheels i6 rotatable on studs d'l upstanding from lateral edge ears $8 on said rail and which are spaced apart around said rail and slidably support the conveyor chain 45.

An electric motor of any suitable type, is bolted, as at to a brace 5i extending between adjacent brace bars 8, e. The motor 49 is arranged with its armature shaft 52 Vertical and operatively connected by a speed reducing belt and pulley drive '53 to a vertical shaft 54 suitably journalled in the conveyor supporting rail! and provided with a driving sprocket wheel 55 arranged in driving engagement with the conveyor chain 45; Anysuitable and usual controls, not shown, may be provided for the motor 59 and said motor may be connected in any usual manner to a'source of electrical energy.

Verticall extensible couplings are provided between the conveyor chain :iii and the carriages zsm the form of U-shaped links 55 straddling said conveyor chain with one end rigidly con nected thereto, as at 51, and the other ends thereof journalled on and slidable along upstanding studs 58 provided on the wheel housings 3| of said carriages 26.

Wheeled trucks 59 with open top bodies 60 are provided for wheeling into and out of the stalls 18 on the floor or other base on which the machine is installed.

Referring now to the use and operation of the described invention, the scale beams 20 are overbalanced by setting the counterweights 24 along the same so that said beams swing in one direction, counterclockwise as viewed in Figures 3 and 4, to elevate the track-bridging sections IS in the gaps i5, and so that fowls of different weights placed in the shelves 33 of the carriages 26 will overbalance said beams 20 to swing in the opposite direction, 1. e., clockwise as viewed in Figures 3 and 4. The stops 25 limit such movement of the scale beams 20 in both directions. In the limit of movement of said scale beams 2 0, counterclockwise, the track-bridging sections I9 are aligned with the track l4 and level therewith, whereas, in the limit of movement of the scale beams 28 clockwise, said sections I9 are lowered slightly as shown for instance in Figure 6. With the trucks 59 wheeled into the stalls i8, under the path of travel of the carriages 26, and the motor 49 driving the conveyor chain 15, the shelves 33 may be loaded with fowls from the side of the machine opposite the weighing and sorting side, and such fowls carried by the carriages 26 around to the weighing and sorting side of the machine. As soon as the trolley wheels 32 of the, carriages 26 ride onto the trackbridging sections 59 of the scale beams 20 adapted to be overbalanced, clockwise, by the weight of the fowl on the carriage shelf 33 such overbalancing of the scale beams 26 occurs and the carriages 26 are lowered suificiently to engage the free ends of the pin raising arms 38 with the screws 44 so. that said arms will be swung upwardly and the trip pins, 35 raised to free the dogs 35. As soon as said dogs 35 are freed, the weight of the fowls will cause the shelves 33 to swing into inverted dumping position, shown in dotted lines in Figure 3, so as to deposit the fowls in the appropriate trucks 59. When the fowls are thus deposited in the trucks 59, the emptied shelves 33may be swung manually back into normal position to engage the dogs 35 with the trip pins 36 so as to lock the shelves 33 in normal position, the carriages 26 having been raised in a manner which will be understood, when the fowls were dumped, so as to position the parts for camming engagement of the dogs 35 with said trip pins. Themanner in which the emptied shelves 33 may be reloaded or refilled will be clear. Obviously, the shelves 33 may be loaded either at the side of the machine opposite the weighing and sorting side, or at the ends of the machine, or both. As will be clear, the fowls are sorted by weight in truck loads by operation of the machine in the manner described.

The foregoing will, it is believed, suffice to impart a clear understanding of my invention, without further explanation.

Manifestly, the invention, as described, is

susceptible of modification without departing,

from the inventive concept, and right is herein reserved to such modificati ns .asfall within the scope of the appended claims.
