EGG-CRATE.

Specification of Letters Patent.

Patented Aug. 22, 1905.

Application filed September 8. 1904. Serial No. 223,722.

Another object of the invention is to produce a novel arrangement of crate-sections which are effectually interlocked in rigid condition when the crate is being carried by hand and which may be readily released for convenience in separating the crate-sections and to give access to the contents thereof.

A still further object of the invention is to permit of the crate-sections beingsuccessively removed from the top to the bottom of the series and to leave the contents of each cratescction supported upon the top of the next below section, thereby to avoid individual handling of the eggs and also to obviate the necessity of removing the cells from the cratesections in order that the eggs may also be removed therefrom, as is usually the case in egg-crates as now in general use.

With these and other objects in view the present invention consists in the combination and arrangement of parts, as will be hereinafter more fully described, shown in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that changes in the form, proportion, size, and minor details may be made within the scope of the claims without departing from the spirit or sacrificing any of the advantages of the invention.

In the drawings, Figure 1 is a perspective view of an egg-crate embodying the features of the present invention. Fig. 2 is a crosssectional view of the crate at the limit of its capacity. Fig. 3 is a fragmentary perspective view looking at the inner corner of one of the crate-sections. Fig. 4 is a similar view showing a modification in the manner of supporting the cells upon one of the crate-sections.

Like characters of reference indicate corresponding parts in each of the several figures of the drawings.

In carrying out the present invention there is provided a base 1, having transverse cleats or sill members 2 secured across the bottom thereof and surrounded by an upstanding peripheral flange 3, the inner wall 4 of which is beveled or inclined downwardly and inwardly. Superimposed upon this base is a series of crate-sections 5, which are duplicates in construction, and therefore a description of one section is deemed sufficient. Each section is rectangular in shape and of an external size corresponding to that of the base and provided upon its bottom edge with a peripheral pend the inner periphery of the section and has its outer beveled face located inwardly or offset from the exterior of the section. At the top of the section there is an upstanding peripheral flange 7, flush with the outer face of the section, with its inner face 8 terminated short of the inner periphery of the crate-section and beveled or inclined downwardly and inwardly, so as to form an upper peripheral rabbet or seat corresponding to the rabbet or seat formed upon the base by the flange 3. The lowermost section has its flange 6 fitted in the peripheral seat or rabbetupon the base, while the successive crate-sections have their lower pendent flanges fitted in the seats 8 at the tops of the respective next below crate-sections, whereby the several crate-sections are snugly assembled and are held against edgewisc displacement.

The uppermost crate-section is closed by means of a flat top 9, having its peripheral edge beveled, as at 10, and of a size to fit snugly within the rabbet or seat 8 at the top of the uppermost section, thereby to lie flush with the upper edges of said section. Across the upper face of the top are stiffening-cleats 11, disposed at opposite edges of the top and projected beyond the latter, so as to rest upon the adjacent top edge portions of the uppermost crate-section.

A bail-shaped handle 12 is employed for convenience in handling the top of the crate and has its opposite side portions directed outwardly to form journals 13, which are re ceived within bearing openings or grooves 14., intersecting the bottoms of the respective cleats 11 and projected beyond the sides of the crate, with the extremities of the journal portions formed into crank or cam terminals 15. A suitable hand-grasp 16 is provided upon the middle portion of the bail.

ent flange 6, which is substantially flush with In order that the several crate-sections may be connected in a rigid manner and capable of being collectively handled as a single crate, it is proposed toclamp the same between the base proper and the top, and this is carried out by means of connections between the terminals of the bail-shaped handle and the base. Each of these connections consists of a plurality of links, three such links being shown in the drawings and designated 17, 18, and 19, respectively, of which the lowermost link 17 is pivotally connected to one edge of the base, as at 20, the other links being pivotally connected to one another by means of eyelets 21 and 22, there being an eyelet or perforation 23 in the free extremity of the uppermost link 19. Each of these links is of a length to project slightly above and below the adjacent crate-section, whereby when the handle is applied the uppermost seat or perforation of the adjacent link may be engaged with the cam or crank terminal 15 of the handle when the latter has been folded down against the top of the crate, whereby upon raising the handle into its operative position the cam or crank 15 will operate to place a tension upon the connection, and thereby bind the crate-sections between the base and the top members.

It will here be explained that the number of links in each connection determines the number of crate-sections which may be assembled in a single crate, or, in other words, the capacity of the crate in sections corresponds to the number of links in each connection. WVhen the greatest number of sections are assembled, the cam or crank terminals 15 of the handle are engaged with the upper openings or seats of the uppermost links, and when a less number of sections are employed the upper links are turned down, as indicated in Fig. 1, and the crank or cam terminals engaged with the adjacent openings or eyelets, whereby any number of crate-sections may be assembled within the capacity of the link connections.

Each crate-section is of course provided with a collapsible cell 24: of the common or any preferred type, and each cell rests upon a support consisting of an inner annular shoulder 25, provided within the crate-section and substantially flush with the lower edge of the bottom flange 6 thereof, said inner annular shoulder being formed by angle-bars secured to the respective sides of the crate-section.

By this arrangement of parts the cell is supported upon the crate-section when the latter is lifted from the lower sections. A plate or horizontal partition 26 is supported within the bottom of the rabbet or seat at the top of each cratesection, and thereby constitutes bottoms for the respective upper sections, so as to support the eggs therein, whereby upon lifting any section from the next below section the eggs of the upper section remain upon the plate or partition and are prevented from rolling off by the upstanding peripheral flange 7 of the next below section, whereby it is not necessary to individually remove the eggs from the section in order to remove the cell therefrom, as the latter is carried with the section when said section is taken from the crate. This is a very important advantage of the present device, for the reason that it obviates the necessity of individual handling of the eggs from the respective crate-- sections, and the cells may remain within the sections at all times, which saves wear and tear thereon and materially increases the life of the crate.

In Fig. 4 of the drawings there has been shown modified means for the support of a cell, wherein the support is a corner-bar 27 at the bottom of each corner of the crate-section, with its terminals bent up and driven into the bottom of the lower flange 6, thereby to form a corner-brace in addition to supporting the cell.

Having thus described the invention, what is claimed is 1. In a crate, the combination of a base, a series of superimposed crate sections supported upon the base, a top upon the uppermost section, cams carried by opposite edge portions of the top, connections extending between the base and the cams and consisting of pivotally-connected links having openings for individual engagement with the respective cams, and means to actuate the cams to place a tension upon the links.
