Claims. (01. 105-367) My invention relates to an improved means for loading cars with fruit, or other perishable merchandise placed in packages for transportation.

In order to better understand my invention it is here noted that the present method for loading cars with boxes, crates, packages, or lugs,

- hereinafter referred to as lugs, for transportation,is to place the lugs in rows crosswise in the end of the car, nail car strips across the top of the row of lugs to more securely hold them from shifting and being jostled in the car, then to place a second row on the top of the first described row, and again nail strips thereon, and so continue until a tier of rows are thus constructed, and in the same manner build successive tiers to fill the car. In order to keep the load of lugs from side shifting and jostling about in the car durin transportation, it is necessary to place the lugs close together in the row so they support each other, and likewise to put the tiers close together to form a solid pack, or load. As the inside widthof the car is seldom an exact 7 multiple of the length of the lugs, unwanted spaces in this form of loadingexist between the load and the .walls of the car. To compensate for these spaces between the wall and the load, the car strips are extended 'at'eitherend so the alternate car strips bear against opposite walls of the car. This is the only means provided in the present used method, to prevent the load of lugs from shifting sidewise, thus loosening the load, and subjecting the lugs to be jostled in the car. As the car strips are normally one-half inch in thickness and two inches, in width the precaution stated for preventing side shifting is not sufllcient. This results in extensive damage to fruits and merchandise thus loaded which is.

shipped long distances, through the shifting of the load and resultant broken lugs and packages.

It is also noted that in unloading the car, the .strips must be torn orripped from the lugs to which they were nailed, which procedure likewise results in broken lugs and damaged fruit.

It is further noted that when the lugs of fruit are packed closely-together, forming a compact load as hereinbefore described, the only oppor-' tunity to secure ventilation between the lugs is through the small open spaces between the top of one lug and the bottom of the lug next above, the lugs generally being provided with cleats on the top and on the bottom to provide said space.

In my invention I have overcome those objections and have accomplished the following obiects:

The arrangement of the-lugs forming the load,

with my improved spacers, form a rigid, firm and compact load which cannot shift, and will more easily withstand the shocks given to the car in transportation, thereby eliminating excessive breakage and damage to the lugs and contents which is now prevalent.

Y Each individual lug is braced and made secure at all four corners.

My improved method and means for loading the car holds each lug separate and apart from the adjacent lugs, thereby providing complete and adequate spaces around each individual lug for ventilation, and for refrigeration, both of which are highly necessary and desirable in the shipment of perishable products.

Skilled labor for loading the car is not required.

I eliminate the nailing of car strips to the lugs, and thus avoid damage occasioned by ripping off such strips when the car is being unloaded.

A car only partly filled can have the load thereon rigid, braced, and compact as a complete load.

To accomplish these objects I have invented the following described method, together with my improved spacers, for loading cars for transportation, described in the following specification, and illustrated on the accompanying drawings, hereby made a part of this specification, in which,

Fig. 1 shows a top plan view of a plurality of lugs packed into a 'car with my spacers in use,

a fractional view of the car only being shown.

Fig. 2 is an enlarged unit view,of a spacer, or

post, which is inserted at the meeting corners of the stacked lugs.

Figs. 3, 4 and 5 are each enlarged unit views of modified forms of spacers which can be substituted for the form shown in Fig. 2.

Figs. 6, 7 and 8 are modified forms of spacers which are to be used at the sides, ends and corners ofthe car' and adjacent to the load.

Fig. 9 is a wedge adapted to occupy space when the width of the car is wider than a multiple of the width, or length of the lug and spacer.

Fig. 10 is a perspective view of a portion of a load in a car, the .view being taken from end of g the pack of lugs.

Fig. 11 is a fractional view of a wall, a stack .of lugs, and wedge means for holding the stack of lugs against the wall. I r

Fig. .12 is an individual lug packed with fruit. In the drawings, 9 represents a single lug of the a general character of lugs used. for transporting grapes and fruit. It is rectangular in form, and they are made of uniform size for ease in handling and shipping. One form of spacer, 8, is

shown in Fig. 2. This spacer is constructed of two strips of material which is approximately two inches square and the length of the height of the load, although variations from these dimensions can be made without departing from my invention. A board of approximately the same length, and wider than the thickness ofthe strips is inserted between the two strips. II and II, and the three piece 'are fastened together so they form a post, with the board forming tongues II and I2 projecting from opposite faces of the p st. It is noted that a cross section of said spacer 8 would be in the form of a cross, as shown in Fig.- 1. The side walls of the car are shown as It, and the rear wall of the car is indicated as Iii. Modified forms of spacers are shown in Fig. 8, which is a right angle form 80, to be used in loading in the corners of the car, spacer ll, shown in Fig. 6 having one of the tongues removed, which form is to be used along the side walls of the car, and a form ill shown in Fig. 7

in which one of the strips is omitted, said form il being used as a spacer at the end wall of the car. i

The loading of a car with these spacers is as follows: The lugs are arranged in a stack Ii the height it is desired to make the load, and the loading is started in one corner of the car with spacer Bil used in the car corner, spacer I placed against the back wall llil at a corner of the lug, and a spacer 40 placed along the side wall ll of the car at a corner of the stack of boxes. Then additional stacks of lugs are formed and positioned along the end of the car with spacers ill placed against the back wall IM of the car, the strip 83 functioning as a spacer to hold the stacks a spaced distance apart, and the board "-82, functioning to space the stack of lugs from the rear wall. The stacks of lugs arranged in this manner across the end of the car ties. As shown in drawings, there is a space between the top of one lug and the bottom of the next adjacent lug, when said lugs are stacked,

which space is provided by cleats 80 and 91, shown in Fig. 12, and spacers 8 provide open spaces on the sides and ends of the lugs. To further promote ventilation, and adequate refrigeration form a tier of stacks, and provides open spaces 20 between the stacks of boxes, shown in Fig. 10. spacers! are then positioned adjacent to openings III. with strip 84 forced into space 20. This leaves recessed openings between the projecting strips II into which stacks of lugs are placed to form the next adjacent tier of lugs. The loading is thus continued with the use of spacers ill at the endsof the tiers of lugs and against the side walls III of the car, and spacers between the stacks of lugs, until the aproximate center of the car is reached. Thus, in plan view. as shown in Fig. 1, the loading forms a checker board arrangement with parallel rows of stacks extending atright angles to one another. The other half of the car is then loaded in the same manner. and the two end packs forming the car load are then braced against each other, and against the ends Ill of the car by well known means of bracing not shown herein. I

Itis noted that if the tier of lugs and spacers inserted between the stacks of lugs do not at tightl between the walls ll of the car, wedges ill, shown in Fig. 9, can be inserted between the spacers at the ends of the tiers of lugs, and the wall ill of the car is shown in Fig. 11.

Another means for thus tightening the tiers of lugs between walls III of the car is accomplished by using theform of spacer shown in Fig. 3, in which strips Ill and I are formed with converging sides to form a wedge. When these wedge formed strips are forced in openings Ill, they spread the stacks of lugs apart and thus occupy more space. i

It is noted that one of the objects of my inwhich can be accomplished better with ventilation, I have provided a modified from of spacer 8, shown in Fig. 4. by providing a plurality of cross members ll which are substituted for the board "-82. these cross members 88 being spaced apart and clamped between, and attached to strips 83 and I4. I have also used the form of spacer shown in Fig. 5 in which a plurality of holes I0 are formed through the spacer along the line of strip 83.

Figs. 1, 1,0 and 11 show the boxes empty, as

these figures were primarily intended to illus-- stacks and tiers rigidly in said spaced relation,

consisting of a post formed of two rigid strips attached together with members clampedbetween said strips, said members extending beyond the faces of the two rigid strips, said strips and portions of the members extending beyond the faces of the strips'being adapted to snugly enter the interstices between adjacent stacks of packses.
