3,022,900 STACKENG (RATES GR RECEFTACIES Charles C. Averill, Albion, Mich., assigner to Union Steel Products Company, Albion, Mich. Fiied dan. l1, 1960, Ser. No. 1,564 14 Ciaims. (Cl. 21tr-126) This invention relates to improvements in stacking crates or receptacles.

The main objects of the invention are:

First, to provide stacking crates or receptacles which when stacked provide free access to the interior of the crates and which may be compactly nested for transportation and storage.

Second, to provide a stacking crate or receptacle, a plurality of which may be stacked and when stacked aord free access to the contents, and at the same time may be compactly nested.

Third, to provide a receptacle or crate having these advantages in which a superimposed crate serves as a bracing element for the walls on which it is superimposed.

Fourth, to provide a structure having these advantages which may be formed of relatively light stock and at the same time is capable of carrying relatively heavy loads.

Objects relating to details and economies of the invention will appear from the description to follow. The invention is pointed out in the claims.

A preferred embodiment of the invention is illustrated in the accompanying drawings, in which:

FIG. l1 is an end side elevational view thereof.

FIG. l2 is a `fragmentary View in section on a line corresponding to line 12-12 of FIG. ll. l

In the embodiment of my invention illustrated, the crates or receptacles are formed entirely of wire or light rod stock, with the exception of the stacking lug seats. It should be understood that the Various parts are welded together at their point of contact, but I have not illustrated the welds for the parts except for the stacking lug seats to their support members.

This invention is an improvement upon and an adaptation of certain features of my pending application, Serial No. 784,226, filed December l1, 1958, now Patent No. 2,950,825.

The crates or receptacles illustrated are well adapted for the handling of various products with the receptacles in stacked, relation, the contents of each receptacle being accessible and the contents of the crates may be of the same general type or may be of varying types as desired.

The embodiment of my invention illustrated comprises the bottom border frame designated generally by the numeral 1 and the top border frame designated generally by the numeral 2. These frames are of generally rectangular shape, the bottom border frame being of such dimension relative to the top border frame that it may be inserted therethrough for nesting the receptacles. The bottom border frame comprises the front member 3, rear member i and side members 5, these being formed of wire or rod stock bent into shape, the ends of the rod not being illustrated.

The top border frame comprises the rear member 6 and side members 7. The side members 7 terminate in the downwardly projecting uprights 8 integral therewith and connected at their lower ends by the bar 9, which is superimposed upon and lixedly secured to the bottom slats 10 which are superimposed upon and secured to the front and rear members of the bottom border frame. The contacting parts are welded together, the welds however not being illustrated.

The rear slats il are preferably straight, but disposed in an inclined relation to facilitate nesting. The side slats I2 are secured at their lower ends to the inner sides of the sidefmembersof the bottom border frame and at their` upper ends to the outer sides of the side members of the top border frame; These side slats have upwardly facing inner shoulders 13 and downwardly facing shoulders i4 adjacent their upper ends. These slats are reinforced by means of the intermediate frame member designated generally by the numeral' l5 and comprising the rear member` I6 and side members i7, these being arranged on the inner sides of and tixedly secured to the rear slats and to the side slats. They serve not only as reinforcing mernbers, but as slides for the rear tacldng lugs 18 facilitating nesting, as is illustrated in FIG. Si The bottom border frame side members are bowed outwardly to provide front supporting lugs I9 and are looped inwardly at Ztl to provide clearance for the front stacking lug seats 2l which are adapted to receive the stacking lugs 19 when the receptacles are stacked. The rear stacking lugs seats 22 are of such length that the stacking lugs 18 may be slidably engaged therewith to facilitate stacking, that is, the rear lugs of the receptacle may be slidably engaged with the lug seats 22 and moved rearwardly until the loop-like front stacking lugs 19 are above the upwardly projecting detents 23 and lowered thereover or into locking engagement therewith, as is illustrated in FIG. 4. The front stacking lug seats are also provided with stops 2.4 at their front ends which serve the double purpose of stops limiting the forward movement of the superimposed crate and as guide members for the front stacking lugs as the superimposed crate is lowered into position, see FIG. 4. With this arrangement, the superimposed crates are very securely retained in their stacked relation and when in stacked relation each crate or receptacle is open at the front. I

The braces 27 extending between the upright members 8 and the horizontal cross member 9 serve to support the front end of the crate sides. However, inasmuch as the detents 23 are engaged by the loop-like stacking lugs 24 when the receptacles are in stacked position, the superimposed receptacle serves as a tie member for the front ends of the side walls. The side members 17 of the intermediate frame v15 are positioned relative to the shoulders 13 so that they serve as ways for the rear lugs, thereby facilitating the nesting of the receptacles. The end members being in supported relation to the shoulders I3 when the receptacles are nested prevents their becoming wedged. The shoulders 14 being in supported engagement with the top frame end members as is illustrated in FIG. 7 prevents substantial lateral shifting of the stacked receptacles relative to each other. With this arrangement of parts,

the receptacles may be very easily and quickly assembled in stacked relation and may be easily separated. As stated, when stacked they are securely retained in their stacked relation which permits their being handled as a stacked group or as a nested group.

The top border frame end members 7 are, in the embodiment illustrated, provided with downward offsets 25 which serve as thrust abutments for the stacking lugs so that twisting strain on the Welds 26, see FIGS. l0, 11 and l2, is substantially reduced. This is of substantial importance inasmuch as the contents of the crate are frequently heavy.

I have illustrated and described my invention in a highly desirable commercial embodiment thereof. l have not attempted to illustrate other embodiments or adaptations which I contemplate, as it is believed that this disclosure will enable those skilled in the art to embody or adapt my invention as may be desired.
