When the U-shaped brackets are in raised position, they wlll support a box 5 thereon until they are tilted by a longitudinal move ment of the hon in the direction of travel or" the conveyors, which is in the direction of the arrow a, Figure 3.

in paomno standsat present constructed, it

is necessary for the packer to lift the filled boxes and deposit the same onthe conveyor, and this is a laborious operation. Inthe present device device there is no lifting of the boxes.

The packing stand proper comprises a base l4 which is supported on casters ii of conventional structure, so the stand can be moved towards and away from the conveyor side. Extending upwardly from the base 14 are uprights i6 connected together by a cross bar l1. Rotatably mounted in bearings l8 in the upper end of the uprights 18 are axially alined arm carrying shafts l9, which extend towards each other and are rotatably mounted in a sleeve 20, which has ing the device to boxes of different lengths.

Secured to the outer ends of the shafts l9, which rotate in unison, are box supporting arms 24, which incline slightly upwardly; and on which the box rests during a packing operation, andv the stand is away from the side of the conveyor,

thereby allowing any other boxes moving on the conveyor to be conveyed and during which action the conveyed boxeswill engage the various brackets at the various packing stations, and swing the same downwardly until the box passes the bracket and at which time it will move to vertical position under the influence of its spring.

Rotatably mounted in bearings carried by the uprights I6 is ahorizontal shaft 25, which is' provided with latching discs 26. One side of the latching disc is provided with a recess 21, and the latching arm 2| extends downwardly and inwardly and terminates in a nose 28, which rides on the periphery of the disc 26 for holding the arms 24 in raised positiorras shown in Figure 4. When the stand is pushed towards the conveyor and the arms 24 are over the conveyor, a trip arm 29 carried by shaft 25 is rocked in the direc-.

tion of the arrow b, Figure 4, and disc-261s rotated to a point where the latch arm nose 28 will enterthe notch 21, thereby allowing the box supporting arms 24 to move downwardly, and the box to be deposited on the hinged brackets 8, and at which time the stand is withdrawn from the conveyor to move the arms 24 from an overlyingrlation to the conveyor and then the packerimparts a longitudinal push on the filled box. This action will tilt the brackets 8 and deposit thebox' on ,the conveyor chains. The above action is repeated as each box is filled and placed on the conveyor.

It will be noted that as the stand is pushed towards the conveyor, trip arm 29 engages the side of the conveyor for the tripping operation. Trip arm 29 is provided with stop arm 30, which limits the pivotal action of the trip arm and maintains the same in position. If desired a spring 8| may be provided for positivelyreturning the trip arm to normal position for resetting the arms 24, as it is obvious the operator, before putting the empty box on the arms 24 could raise the arms 24 slightly and spring 8l would rotate disc 26 to its proper position so the latching nose 28 would engage the periphery thereof, and notch 21 would be in position for the next unloading operation.

From the above itwill be seen. that a fruit and vegetable packer's stand is provided, which sary for the packer to lift boxes as they are filled,

and deposited on the conveyor.

The invention having been set forth what is claimed as new and useful is:

1. The combination with a conveyor having tiltable receptacle supporting means for supporting a receptacle above the conveyor until tilted, of, a truck movable towards and away from one side of the conveyor, said truck having receptacle supporting arms at an elevation above the tiltable receptacle supporting means on the conveyor, latching means carried by the truck and cooperating with the arms for maintaining said arms elevated above the tiltable receptacle supporting means and latch releasing means carried by the truck and positioned to engage the side of the conveyor when the truck is moved towards the conveyor when the receptacle is supported above the tiltable receptacle supporting means on the conveyor.

2. A conveyor loading truck for loading a conveyor from the side thereof, said truck comprising a movable frame movable towards and away from the side of the conveyor, said frame having pivoted receptacle supporting arms at its upper end above the conveyor, latching means carried by the frame and cooperating with the arms for maintaining the same elevated above the conveyor and latch, control means carried by the frame and positioned to engage the side of the conveyor for releasing the latch control means of the arm when the truck reaches its limit of movement towards the conveyor and the receptacle supporting arms are disposed above the conveyor.

3. A receptacle supporting truck adapted to be moved towards the side of a conveyor for depositing receptacles on the conveyor, said truck com prising a frame, a rock shaft in the upper end of said frame, receptacle supporting arms carried by said rock shaft and adapted to support receptacles at an elevation above the top of the conveyor and toextend across the top of the conveyor when the truck is moved towards the side of the conveyor, latching means for maintaining said receptacle supporting arm in raised position and latch releasing means carried by the truck and positioned to engage the sidepf the conveyor as the truck reaches the limit of its movement towards the conveyor forallowing the receptacle supporting arms to move downwardly for depositing a receptacle on the conveyor.

4. A device as set forth in claim 3 wherein the latching means comprises a rockable shaft carried by the truck, notched arms rigidly mounted on said shaft, latching arms carried by the receptacle supporting arm shaft and engaging the cams, said latching arms having members .slidably engaging the cam surfaces of the cams and receivable within the notches thereof upon release of the latching means.

5. A device as set forth in claim 3 wherein the rock shaft in the upper end of the frame is formed from axially alined sections each of which carries a receptacle supporting arm, a sleeve mounted on said axially alined sections and bayonet connections between the shaft sections and the sleeve, whereby the receptacle support- 70 ing arms may be adjusted in relation to each other.
