5 Claims. 1

My invention relates to chick boxes, and more particularly to that type of chick box provided with a cover bearing spacing members which prevent a superposed box from occluding ventilation openings in the cover. my invention to produce a spacing member which can be made of corrugated board or similar material, which can readily be attached to the cover, and which will be suf iciently strong and rigid to provide a support for one or more superposed boxes. i

In carrying out my invention, I form the spacing member from a generally rectangular blank of corrugated board or similar foldable material.

This blank is folded about three transverse fold- 5 lines to produce a central wall of double thickness and two divergent side walls. The cover is slotted to receive the lower edge of the center wall and also to receive ears on the lower edges of the side walls. That portion of the central wall which projects through the cover is reduced in width to provide shoulders which rest on the top surface of the cover and transmit thereto the load resulting from another box supported on the spacing members.

The accompanying drawing illustrates my invention: Fig. 1 is a fragmental plan view of a chick box provided with my improved spacing members; Fig. 2 is a fragmental end elevation of the chick box on an enlarged scale; Fig. 3 is a vertical section on the line 3--3 of Fig. 1; Fig. 4 is an end elevation of the spacing member in place on the box-cover; and Fig. 5 is a plan view of the blank from which the preferred spacing member is formed.

The box shown in the drawing comprises an open-topped box-body l and a cover ll therefor. The box-body and the cover are provided with a multiplicity of distributed ventilation openings 12 and may be formed of any suitable material, such as corrugated board.

The spacing members which are to be attached to the box cover may be arranged thereon in any desired pattern; but I prefer an arrangement in which. the members include four extending obliquely across the corners of the cover I l in the manner indicated in Fig. 1. In such an arrangement, the cover is provided at each corner with an obliquely extending slot l which terminates short of the edges of the cover. Between the slot [5 and the adjacent cover-corner, a shorter slot I6 is provided; and on the opposite side of the slot I5 two alined slots I! are provided. The slots l6 and I! extend parallel to the slot 15.

The spacing member which is to be associated It is the object of divided'by three transverse fold lines 2!] into four

panels

2 l, 22, 23; and 24. The panel 2| is provided at the end of the blank with two spaced ears 25, while the panel 24 is provided at the opposite end of the blank with a single centrally located ear 26. .The side edges of the blank are provided respectively with notches 21 having parallel side edges 28 located at equal distances from the center fold line, 29. Inca-ch of the panels 22 and 23 I provide an elongated tongue 30 defined by a fold line 3! spaced a short distance from the center fold line 20 of the blank, 3, cut 32 parallel to the fold line 3|, and1cuts'33 interconnectingthe ends of the cut 32 with the ends of the fold line 3|.

In erecting the spacing member from the blank shown in Fig. 5, the blank is folded about the center-line 20 to bring the

panels

22 and 23 into superposed relation, and the panels 2| and 24 are then folded in the opposite direction about the end fold lines 20. Those portions of the

panels

22 and 23 which are reduced in width by reason of the presence of the notches 21 form an car, which is inserteddownwardly through the slot IS in the box-cover ll until the side edges 28 of the notches rest on the upper surface of the box-cover, as shown in Figs. 2, 3, and 4. The tongues 30 are so disposed that with the'cleat inserted in the slot l5 as above described each tongue will spring outwardly beyond the plane of its associated panel in the manner indicated in Fig. 4, in order that its upper edge will engage the lower surface of the box-cover l I and prevent removal of the spacing member. The tongue 26 is inserted in the slot I6, and the tongues 25 are inserted in the slots IT.

The width of the blank is such that the

superposed center panels

22 and 23 will extend substantially to the side edges of the cover when the spacing member is in place. To prevent the ends of the panel 24 from projecting beyond the sides of the cover, they may be beveled as indicated at 35 in Fig. 5. As a result of this arrangement,

any load applied to the top of the spacing member is transmitted directly through the substan tially vertical, double-thickness wall 22-23 to the box-cover ll through the shoulders 28," and such load is then transmitted directly through the box cover to the side walls of the box body ID, as will be clear from Fig. 3. The end panels 2| and 24 of the blank, which occupy an inclined position when the spacing member is in place, may aid in transmitting some of the load, but their chief function is to maintain the center wall 22-23 in a substantially vertical position. When the blank is formed of corrugated board, the corrugations desirably run longitudinally of the blank so that they will extend vertically in the center wall 22-23 and provide increased stiffness and strength forsuch center wall.

I claim as my invention:

1. In a chick box having a body and a cover, spacing members secured to the cover on the upper side thereof to support a superposed box, each of said spacing members comprising a central vertical wall and two inclined walls which are vertically coextensive with said vertical wall and which extend obliquely between the top of said vertical wall and said cover, said walls being provided at their lower edges with ears, and said cover being provided with slots in which said ears are received, at least one of the ears on said -central wall carrying releasable means engageable with the lower surface of the cover to prevent removal of said ear from the ear-receiving slot in the cover.

2. In a chick box having a body and avcover, spacing members secured to the cover on the upper side thereof to support a superposed box, each of said spacing members being formed of corrugated paper and including a central vertical wall of double thickness and an inclined wall extending from the top of each thickness of the central wall to said cover, said walls being provided at their lower edges with ears, and said cover being provided with slots receiving said ears, at least one thickness of said central wall being provided with an integral tongue engageable with the lower surface of said cover to prevent removal of the spacing member.

3. A spacing member for use on the cover of a chick box, said member comprising a generally rectangular blank of foldable material, said blank being provided in opposite edges with similar notches, each of said notches having parallel side edges respectively alined with the side edges of the other notch whereby said notches will have a common center-line, said blank being folded upon itself about said center line, the end portions of said blank being folded away from each other on lines parallel to said center-line, said end portions being provided with ears at their outer edges.

4. The invention set forth in claim 3 with the addition that said blank is provided on opposite sides of said center-line and between said notches with integral tongues having free edges parallel to and spaced from said center-line.

5. The invention set forth in claim 3 with the addition that said blank is provided on one side of said center-line and between said notches with an integral tongue having a free edge parallel to and spaced from said center-line.
