ATTORNEYS Patented Nov. 17, 1931 r 1 FRED MYERS, OF FALLBROOK, CALIFORNIA PACKING STAND Application filed 'April 30,

My invention relates to and has for its purpose the provision of a simple, substantial and inexpensive packing stand particularly adapted, although not necessarily, for use in citrus fruit packingplants, and by which the packing of fruit in the different compar ments of the conventional form of crates or boxes is greatly facilitated, and themanual labor attendant the necessary moving and shifting about of the box with respect to the usual traveling conveyor from which the fruit to be packed is removed by the operator, tothe positions most convenient to the operator for the packing of the fruit in the different compartmentsofthe box, is reduced to a minimum, and the manipulation of the box while packing the fruit therein accomplished with the utmost ease and dispatch and to the entire elimination of any lifting 29 or other physically fatiguing labor on "the part of the operator. 7

I will describe only one form of packing stand embodying my invention and will then point out the novel features in claims.

In the accompanying drawings,

1928. Serial No. 274,111.

Figs. 8 and 9 are enlargeddetail sectional views taken respectively on the lines88 and 99 of Fig. 5, and illustrating one of two latching devices embodied in the packing stand.

Referring specifically to the drawings in which similar reference characters designate similar parts in eachof the several views, my invention in its present embodiment comprisesa support designated generally at S constructed ofwood 'or other suitable material to provide two pairs of upright members 10' and 11, with themembers of each pair rigidly connected together in spaced and up.- wardly converging relation by means of upper and lower transverse rails 12 and 13 respectively, .while the upright members of one pair are rigidly connected in spaced parallel relation to those of the other pair by 'upper and lower longitudinal rails 14 and 15 respectively, to the end that all of the members will co-operate .to form a rigid skeleton frame which is mounted for rolling movement over the floor by means of casters 16 secured to the lower ends of the pairs of upright members 10 and 11.

To provide means for supporting a box B to be packed with fruit, in an elevated position on the support, a platform designated generally. at P is shown; and means is providedfby which the platform is mounted for movement on the support to occupy a horizontalposition as shown in Fig. 4 or either one of two inclined or tilted positions as shown in Figs. 2 and 6. p

The platform P in the present instance comprises a pair of longitudinal bars 17 of L shaped cross section rigidly connected in spaced parallel relation by transverse bars 18 also of L shaped cross section and secured to'the undersides of the longitudinal bars by fastening members 19. Spanning the longitudinal bars 17 area plurality of rollers 20 having stub shafts 21 at their ends ournaled in the vertical portions 22 of the longitudinal bars. Upon the rollers, the box or'crate to be packed with fruit is adapted to rest,'andit will be appreciated that while the rollers normally firmly support the box, they permit 7 the box when'fully packed with fruit to be rolled from the platform with a minimum amount of laber on the part of the operator.

The means for mounting the platform for movement in the frame to occupy is two oppositely tilted positions and its horizontal position comprises in the present instance two frames designated generally at F and F which are mounted for vertical movement in the support S at opposite sides thereof. As the frames F and F are identical in construction a description of one will suffice for both, and to distinguish the reference characters of one frame from those of the other, the characters for the parts of one frame are provided with exponents.

The frame F comprises a pair of upright members 23 disposed at the inner or confronting sides of one of the members of each pair of members 10 and 11 of the support S and pivotally connected at. their upper ends by bolts 24 to the transverse bars 18 of the platorm P, while the upright members 23 are tied together in definite spaced relation adjacent their lower ends by a single horizontal member 25. The extremities of the horizontal member 25 project beyond the upright members 23 and ride upon the outer sides of the members 10 and 11 of the support S as the frame F is raised or lowered to thus prevent inward displacement of the frame F, and it will be clear that as the latter is raised or lowered, a corresponding movement will be imparted to one side of the platform P. Such movements of the other frame F will impart corresponding movements to the opposite side of the platform, to the end that with the frame F lowered and the frame F raised as is shown in Figs. 2 and 3 the platform P will be inclined towards one side; and with the frame F lowered and the frame F raised as shown in Fig. 6, the platform will be inclined towards the opposite side, whereas with both frames F and F raised as shown in Figs. 4 and 5,'the platform will occupy a horizontal position.

For each of the frames F and F I provide an actuating mechanism by which the frames can be moved to their raised positions and releasably retained or latched therein, and as these two mechanisms are identical, a description of one will suffice for both, the reference characters designating the parts of one mechanism being distinguished from those of the other by exponents.

The actuating mechanism for the frame F comprises a foot actuated member in the form of a lever 26 pivot-ed at one end at 27 on the outer side of the horizontal member 2 of the frame F and projecting at its free end beyond one end of the support S. Pivoted at 28 on a lower longitudinal rail 15 of the support S is a link 29 pivotally connected to the lever 26 at 30, while an equalizing lever 31 is pivoted medially between its ends at 32 to the rail 15 of the support S. To one end of the equalizing lever 31 is pivotally connected a link 33 pivotally connected at 34C to the actuating lever 26, and to the other end of the equalizing lever is pivotally connected a link 35 in turn pivotally connected at 36 to said horizontal member 25 of the frame F. Upon depression of the free end of the actuating lever 26 by the foot of the operator, from the position shown in Fig. 3 to that shown in Fig. 5, it will be clear that through the medium of the compounded lever system above described the frame F will be raised to the position shown in the latter figure to impart a corresponding movement to the respective side of the platform P.

To provide means for latching the frame F in its raised position, the free end of the actuating lever 26 is bent back upon itself to form a latching arm 37 which in the depressed position of the lever is adapted to be engaged with a keeper 38 secured to the upright member 11 of the support S. The latching of the lever 26 in its depressed position is effected by a slight lateral shifting of the free end of the lever towards the keeper as the foot of the operator depresses the lever, and the unlatching of the lever is effected by a slight reverse lateral movement of the latter, thus permitting the frame F to gravitate to its lowered position under the weight of the platform and the box supported thereon.

t will be understood that the actuating mechanism for the frame F is associated with the horizontal member 25 of the latter and the lower longitudinal rail 15 at the opposite side of the support S in the san'ie manner just described for the actuating mechanism of the frame F, to the end that the free ends of the actuating levers 26 and 26 will project from the support S at diagonally opposite corners thereof for actuation of the respective frames independently of each other.

The lower ends of the members 23 and 23 of the frames F and F respectively are provided with friction elements 39 in the form of rubber buttons which engage the floor when the frames occupy their lowered positions, thus definitely limiting the lowered positions of the frames and positively prethe platform P under the action of gravity 1 5 when the platform occupies its inclined positions, stop members designated generally at M are provided, one at each end of the support S, and each comprising a length of strap metal secured upon the top side of an upper transverse rail 12 of the support S and having its free ends bent upwardly to provide abutments 40 which are disposed in the path of movement of the box should the latter tend to slide downwardly on the platform under the action of gravity. However, when the platform is in its horizontal position, the bottom of a box on the platform will clear the upper extremities of the abutments 40 so that the latter will not interfere with rolling of the box off of the platform.

In the operation of the packing stand, reference will first be had to Fig. 1 wherein C indicates a conveyor alongside of which stands an operator who is facing the pack ing stand which has also been rolled to a position alongside of the conveyor and has a box B to be packed with fruit, supported on its platform P. The operator stands sufficiently close to the conveyor as at X to conveniently reach and remove fruit from the conveyor with one hand as the conveyor travels in the direction of the arrow.

Let it be assumed that the platform P has been adjusted on the support to one of its inclined positions wherein the box 13 will be tilted downwardly towards the operator so that the latter can conveniently reach into the compartments 41 and 42 of the box B; and that the side of the platform directly in front of the operator is that which is controlled by the actuating lever 26, the latter being disposed at the forward right hand corner of the support S as is shown in Fig. 1. The operator now removes an article of fruit from the conveyor with the right hand and wraps the article with tissue pap-er, after which the article is placed. by the left hand of the operator in the right hand compartment 41 of the box, this operation being repeated until the compartment 41 is filled.

The operator'now steps upon the lever 26 and latches the latter in. its depressed position, which operation raises the side of the platform directly in front of the operator so that the platform and hence the box occupy horizontal positions. I

The friction elements 39 of both frames F and F now clear the floor, so that the operator can now rotate the packing stand bodily on its casters 16, 180 from its former position so that the empty compartment 42 of the box will now be the right hand compartment and the actuating lever 26 occupies the same relation to the operator as previously did the actuating lever 26. The actuating lever 26 which during the filling of-the compartment 41 was latched in its depressed position is now released allowing the side of the platform at present directly in front of the op erator, to lower, so that the platform and hence the box is again inclined downwardly towards the operator. The filling of the compartment 42 is then accomplished in the same manner as was the compartment 41, after which the operator steps upon the actuating lever 26 to move the latter to and lat-ch it in its depressed position, thus again restoring the platform and hence the box to horizontal position.

The operator now rolls the packing stand over the floor to another conveyor (not shown), and then rolls the completely filled box of fruit off of the platform P onto this conveyor. The packing stand is then returned to the conveyor C; another and empty box is placed on the platform P; and the side of the platform directly in front of the operator is lowered, after which the above described operation is repeated.

1 From the foregoing operation, it will be manifest thatbroadly I have provided a packing stand capable of being readily moved from place to place and embodying a means for supporting a box or crate to be filled with fruit, which means is capable of being adjusted in such manner and with a minimum expenditure of manual labor as to dispose a box or crate supported thereon in a position tilted downwardly towards the operator to permit the rapid and convenient filling of both the compartments of the box,

which would be impossible unless reversing of the positions of the box compartments with respect to the fruit delivering conveyor while maintaining the box tilted downwardly towards the operator, could be effected, as the operator cannot remain in easy and convenient reaching distance of the conveyor and of both the box compartments at one end the same time.

Although I have herein shown and described only one form of packing stand embodying my invention, it is to be understood that various changes and modifications may be made therein without departing from the spirit of the invention and the spirit and scope of the appended claims.
