(Cl. 217-69) Our invention relates to the construction of milk crates especially, but not exclusively, of the slatted style, i. e. of the type in which the side and end walls are made up of wooden rails or slats. -5 In such crates it has hitherto been suggested to use inner and outer corner irons between which the slats or rails are engaged. It has also been suggested to provide these corner irons with ears lying between the slats and to fasten the struc 10 ture together with a wire lacing passing through the slats and through the ears. 'I‘he lacing has usually been bent over at the bottom, and shoe members have been provided to cover it. We shall describe our invention in an exem 15 plary embodiment, from a description of which it will be understood that the objects of our in vention are the provision of an improved corner construction, and a novel way of fastening the several parts together, which fastening is strong the shoe member. Locking means are provided forrthe rod. A new type of stacking iron is like wise intended for use with this combination, and is claimed in a co-pending application entitled Milk crate corner assemblies, filed of even date 5 herewith. The general assembly of an exemplary crate is shown in Figure 1, where the sides are indicated at I and the ends at 2. Longitudinal bottom forming rods are shown at 3, and longitudinal l0 and transverse partition forming rods at 4 and 5. Bottom strut members are shown at 6, and arms 1 connect the partition rods at their crossing points and have an operative relationship with the bottom structure. The interior rodded or 16 other construction of the crate, however, has no necessary bearing upon our invention, and will not be further described. Reference to-Figures 2 and 3 will show that the 2o and positive, but easily removed for replacement ‘» sides and ends of our crate are formed of slats Ia etc. and 2a etc. respectively.

Ears I2 are bent up describe the aforesaid exemplary embodiment, normal to the side walls of the corner iron at in tervals. These ears are perforated for a pur reference being had to the accompanying draw pose hereinafter to be described, and are intended 30 _ 30 ing, wherein: to cooperate with the ears on the inner corner Figure 1 is a plan view of a milk crate embody ing our invention. A Figure 2 is an elevational View of a corner thereof. 35 Figure 3 is a sectional view taken along the lines 3--3 of Figure 2. Figure 4 is a perspective view of an outer cor ner iron. Figure 5 is a perspective view of an inner cor 40 ner iron. Figure 6 is a perspective view of a stacking iron. Figure 7 shows a tool for removing the locking rods. ' Figure 7a is an enlarged view of the end of the 45 tool. . Briefly in the practice of our invention we pro vide inner and outer corner irons in a slatted construction, the corner irons having ears lying between the slats. The slats and the ears have 50 registering perforations, and fastening means are provided in the form of a rod which passes through the registering perforations. The outer corner iron is turned over to form a shoe mem ber, and the rod is removable by means of a tool 55 which is insertable through the perforations in iron to lie above, below and between each pair of slats or rails in the sides and ends of the box and to act as spacers therefor. The bottom por tions of the outer corner iron are bent over to 35 form bottom shoe members I3 and then are con tinued upwardly to form interspaced members I4 which terminate in perforated, bent over ears I5. The portions of the side walls of both corner irons Ybetween the ears are preferably beveled as at I6 40 excepting at the top, as shown. The inner corner iron is likewise of angular formation, having top ears I'I, and other ears I8 ìnterspaced therefrom. Whereas in the outer corner iron the ears are bent over inwardly, in 45 the inner corner iron they are bent over out wardly, so that when the irons are assembled Y with the ends of the slats or rails therebetween the ears and the perforations therein may be aligned with each other and with perforations in 50 the slats or rails. By reason of the portions I4 of the outer corner iron, the inner corner iron does not need to be as long. In one embodiment of our invention, we form a stacking iron as a separate piece. This is a 55 2 Ul 2,111,896 member of generally angular cross section hav ing a body (Figure 6) and a stacking extension 2li. This extension is reduced, and offset from the body, and is of the usual shape to permit its It will be understood that modifications may be made in our invention without departing from engagement within the bottom shoes of an over lying crate when the crates are stacked. Upper and lower ears 2l and 22 are struck up outwardly claim as new and desire to secure by Letters the spirit thereof. Having thus described our invention, what we Patent is: 1. In combination in a crate, a corner rein from the body of the stacking iron, and are per forated. They are of a size and shape adapted to permit their alignment with the ears on the crate, ears on said member entering in between said slats, a continuous perforation extending inner and outer corner irons as clearly shown in Figures 2 and 3. Both the corner and the stack continuous perforation extending substantially ing irons are preferably formed as sheet metal stampings, galvanized or otherwise protected 15 from corrosion. In assembling the crate the slats or rails go between the inner and outer corner irons. The ends of the upper rails are notched out as at 23 to bring the top ears of the corner irons substan~ 20 tially into the plane of the top of the crate. The lower rails or slats are also notched out as at 24 to bring the shoe portions I3 of the outer corner irons to the level of the bottom of the crate, and further, to accommodate the offset end of a shoe 25 strip 25 which underlies each bottom rail and which may be riveted thereto, as at 26. The stacking irons are added to the assembly with their ears in alignment with -the ears of the outer and inner corner irons. When the parts have 30 been put together in this way, assemblies of ears underlie and overlie each rail or slat, and act as supports and as ultimate spacers therefor. Per forations in the several metal members and in the slats or rails are brought into alignment, and the crate may be fastened together with rod means to be described hereinafter. y The perforations in the top rails or slats are somewhat larger than the'perforations in the other rails, and also have still further enlarged 40 portions indicated at 26. Rod members 21, which are preferably long enough to extend from the top almost to the bottom of the crate, but are in no event longer than the crate is high, are pro vided with heads 28, and crooks or shoulders 29. These rod members may be driven through the aligned perforations to complete the crate. When they are so driven, the crook 29 in the rods com presses as it passes through the perforation in the top rails, but expands into the enlargement 50 26 of the perforation locking the rods against dis lodgment. The rods may otherwise be expanded, or other suitable locking means provided. The crate, or any corner portion thereof, however, is easily disassembled for repair or replacement 55 either of a corner iron, a stacking iron, or the rails themselves, by merely driving out the rods 21 until the locking means have come above the upper ears or have otherwise been disengaged. This is conveniently done by means of a tool such as that shown in Figure 7, having a handle and driving head 3U, and a shank 3| of about the same size as the rod. The upper end of the shank is preferably hollowed as shown at Sla in Figure '7a so as to provide a positive engagement with the end of the rod. 'Ihe shank of this tool is in serted through the perforations in the shoe mem bers of the corner irons, and when it contacts the end of the rod, is tapped with a hammer until the rod has been driven far enough out to free the crook therein as aforesaid. After this the rod may be easily withdrawn by the ñngers for the remainder of the way. When a new part has re placed the old, the crate is reassembled by rein sei'tion of the rod. There will, as shown, be two of the rods at each corner of the crate. forcement member, slats forming a wall of said through said ears and said slats, a rod in said the full length thereof, and releasable means for holding said rod in said perforation, said means comprising a crook in said rod and a cooperating abutment in said perforation. 2.
