7 Claims. 1

This invention relates to a collapsible metal crate of a type used in the handling and shipment of poultry and animals.

An object of this invention is to provide a collapsible metal crate of strong, Simple and durable construction that is not expensive to manufacture, that can be quickly and easily folded into compact form for storage and shipment and that can be quickly and easily unfolded or opened up for use.

Another object of this invention is to provide a crate that is made entirely of metal thus making it sanitary and easy to clean and sterilize.

Another object is to provide a crate having a flanged bottom portion of slightly larger size than the top of said crate whereby when two or more of these crates are stacked one on another the bottom flanges oi the upper crates will slightly overlap the sides of the crates on which they rest thus providing stability andpreventing relative sliding movement of the crates one on another.

Other objects are to provide a crate having ove and emcient, pr n mean f r lo king he top of the crate to the ends thereof to hold the several parts of the crate in an open position, to provide a crate having a removable partition therein and to provide a crate having side bars that are outwardly offset near their lower ends for more compact folding.

Other objects of the invention will be apparent from the following description taken in connection with the accompanying drawings.

Like reference numerals designate like parts throughout the several views.

This crate comprises a crate bottom It, two crate sides ll, two crate ends it, a crate top or cover l3 and preferably a removable folding partition l4.

The crate bottom I0 is preferably formed or a flat piece of sheet metal having transverse corrugations l5 therein which increase the stiffness or the bottom ill and prevent it from sagging and which provide a better non-skid foothold so that the poultry or animals in the crate will not tend to slide around on the bottom it as much as they otherwise would. The corrugations [5 are preferably upwardly convexed so they extend above the plane of the bottom it, Preferably perforations l6 are provided in the bottom It] to facilitate rapid drainage of liquid.

The corner portions of the bottom H! are ,cut' away, see Fig 4 to Provide corner notches ll. Between these cornernotches li the marginal pflrtions oi the bottom ll] are bent to form upwa dly e ten ing fla p i n l8, u u portions [9 within which a reinforcing wire or rod 2!] is disposed, downwardly extending flange portion 2 a d ther u u p rt ns 2 i hi which ano e re nfor in ire or od 23 is disp sed. o t rm a b The nwardly ext ndins por ion 21 ex end a stant a distan e below the bottom Ill so that said bottom It will be supported clear of the ground or floor.

Slots 24 are provided at spaced intervals in the parts I8, IE! and 2| to facilitate the attachment or the sides II and ends 2 to the reinforcing member 20, as hereinafter explained. These.

slots 24 are preferably punched in the bottom l8 before the marginal portions of said bottom are ent. reierably the portions 2| are res utwardly slightly toward their lower edges to provide a base structur that is well adapted to rest on and extend over the top portion of another similar crate, see Fig. i, in which the lower crate is fragmentarily shown by dot and dash lines.

Each side member I I is formed of a plurality of parallel bars 25 having at their bottom ends eyes 26 that arepositioned in the slots 2t and extend around and are pivotally connected with the reiniorcing rod zuintthe upper edge IQ of the marginal portions or the bottom Hi. Adjacent the eyes 26 the bars 25 have outwardly offset portions 21 which facilitate a compact folding of the crate as hereinafter explained. The upper end portions of the parallel bars 25 are rigidly secured to a horizontal top bar 28. The two end bars 25 at the respective ends of each side member II are preferably integral with the top bar 28, as shown in Figs. 1, 2 and 3.

Each end l2 comprises upright parallel bars 29 having their bottom end portions pivotally connected by eye members 30 with the base rod 20 and having their top end portions rigidly secured to a horizontal top bar 3|. The structure of each end I2 is similar to the structure of the sides just hereinbefore explained except that the upright end bars 29 are slightly shorter than the side bars 25 and do not have any offsets corresponding to the ofisets 21 of th side bars 25. The upright bars 32 at the ends of each end section are preferably integral with the top bars 3|.

The medial partition l4 comprises upright parallel bars 33 having their bottom end portions secured to a tubular member 34 and their top end portions secured to a horizontal bar 35, Fig. 5, that is parallel with the tubular member 34 and is integral with end bars 36. A rod 31 extends through the tubular member 34 and through the marginal parts l8 and 2| of the bottom I6 thereby pivotally mounting the medial partition in the crate. Preferably one end portion of the rod 31 is reversely bent to form a hook shaped end 38, Fig. 5, and preferably a short latch bar 39 is connected by a pivot 40 with the other end portion of the rod 31 for locking the same when it is crosswise of the rod 31 and for releasing said rod 31 when said bar 39 is turned parallel with said rod.

The crate top |2 preferably comprises a plurality of spaced apart transverse bars 4|, 42, 43 and 44 each provided at each end with an eye member 45 that is slidable on the upright bars 25 of the side members H. Longitudinal bars 56 connect the transverse bars 4|, 42, 43 and Y44 of the crate top.

Two longitudinally disposed fiat bars 46 of spring metal extend along the respective sides of the cover member l3 at right angles to the transverse bars 4|, 42, 43, and 44. Each flat bar 46 has a hook portion 41 of inverted U shape on each end thereof. Each hook portion 41 is adapted to releasably fit over one of the end cross bars 4| or 44 of the cover I3 and to also fit over the adjacent top bar 3|, of one of the end members l2, see Fig. '1. .Each spring bar 46 is rigidly secured to some of the transverse bars, such as

bars

42 and 43. Preferably each hook portion 41 is provided with holes 52 through which a pin or bolt 53, Fig. '1, or a tie member can beinserted, if desired, to preclude any possibility of accidental release of the hook portions 41. The pins 53 are omitted in Figs. 1, 2 and 3.

Each spring bar 46 is also provided with means for engaging with the top bar 35 of the partition l4 to hold the partition in an upright position. Fig. 1 shows two spaced apart cleats 55 secured to the bottom side of each spring 46 for this purpose. Fig. 7 shows an integral catch member 48 formed in the spring 46 at the proper location to snap over the top bar 35 of the folding partition l4 and hold said partition in an upright position.

, An opening or doorway for the insertion or removal of poultry, animals or the like from the crate is provided in the medial portion of the top member or cover I3. Preferably two sliding

doors

49 and 50 are provided for closing this opening, said doors being operable respectively to close the two parts of the opening on the two respective sides of the partition I4. This provides for separate access to the two compartments of the crate for inserting and removing poultry or small animals through the top. The transverse bars of the doors are provided with eye members 5| that slide on the longitudinal bars of the top member. A readily releasable spring hook 54 is provided for securing each door in a closed position.

The crate ends l2 can be opened outwardly, as shown in Fig. 3, in discharging poultry or animals from the crate. Obviously a decking can be placed on a lowered crate end ID to provide a better surface over which poultry or animals can walk.

I fgdesired the partition member can be removed from the crate. However the partition will ordinarily be used when the crate is used for poultry or small animals. This partition divides the crate into two compartments and thus minimizes crowding and piling up of the poultry or animals and keeps the load in the crate in better balance.

When the crate is not in use it can be compactly folded as shown in Fig. 2. In folding the crate the partition member I4 is first folded down on the floor; the ends |2 are then folded inwardly with one end resting on the partition member and the other end resting on the floor; the top or cover I3 is then lowered and the sides I folded inwardly on the top thus reducing the crate to avery compact form for storage or shipment. The parts can be quickly and easily opened out and erected into a position ready for use as shown in Fig. 1. The offset portions 21 of the side bars 25 accommodate the eye members 5| of the top or cover without binding or strain as the sides are folded down on the top.

These crates are strong and rugged in construction and can be stacked one upon another when loaded without danger of crushing the lower crates. When the crates are stacked the flaring bottom portions of each upper crate extends downwardly over the top edges of the crate on which it rests thus preventing each upper crate from sliding around on the crate on which it rests. The upright bars 29 of the ends |2 are straight and act as compression members in supporting the load when two or more crates are stacked one on another. The fastening members 41 on the ends of the springs 46 hold the crate ends in an upright position with the end bars 4| and 44 of the top member resting on the top bars 3| of the end members. Thus the end bars 29 and 32 are always maintained in an upright position for the purpose of supporting a load when two or more loaded'crates are stacked one upon another.

Obviously changes in this invention can be made within the scope of the appended claims.
