cover 2 are preferably of cardboard of the Jfolding orknock-down type, so that they may be shipped flat and occupy but rel-atively small space.

The cover 2 telescopes on the body 1 and provides at the four sides of the body, a double thickness of material throughout the egg space between the upper and lower partitions 3 and 4 respectively, which more fully hereinafter described. The partitions 3 .and 4 each comprises a slngle piece ofrfairly heavy cardboard conforming i'n size of the body and spaced from the top Be it known that I, CARL-R. SHAFER, a citizen of the United States 'of America, residin at Detroit, in the county of Wayne tate of Michigan, have invented cer-- tain new -and useful Improvements in Safety E g-Cases, of which the following reference being had. therein to the'accompanying drawings.

My invention relates to improvements in safety egg cases, the obj ect of the invention being to provide a simple, inexpensive casing, which can be utilized for packing "and shipping eggs, and is particularly deslgned for transmitting through the mail, packages of a dozen ormore eggs, utilizing the w and 5. 'This packing 5 may consist of excelslor, A further object is to provide improvements of the character stated which can be shipped flat tothe farmer or shipper, and can be assembled by him as he packs the eggs for shipment. A further object is to provide improvements of the character stated which not only shocks and jars and also' absorb the contents of broken eggs.

Said partitlons, which are preferably duplicates, are provided with a suitable number ofv egg-engaging o enings 6. These openings are formed by rst producing inbottom ofthe receptacle by relatively thick other similar material which will absorbwill be l tothe interior dimensions thoroughly rotect the'eggs from breakage, cisions `at right 'angles to each other as but also ma e provision for absorbing leakshown Y1n Fig. 4, and then bending the tongues or lingers 8 formed by said incisions at an angle to the partition as shown clearly in Figs. 2 and 3.

age from cracked eggs which may have been placed in the package by mistake;

With these and other objects in view, the invention consists in certain novel features of construction and combinations and arrangements of parts as will be more fully hereinafter described and pointed out in the claims. In the accompanying drawings:

.Figure 1 is a broken perspective view openings 6, form resilient or. flexible partitions or spacers between thefeggs `having su'iicient strength to hold theeggs properly spaced, and yet of -sufficient .elasticity or iexibility to compensate for'various sizes "and conditions -of. the eggs. Between thev partitions 3 and 4 are .air spaceswithin which the tongues 8-permit alimited lateral movement of the eggs,.whereby shocks or blows acting on the package Iare absorbed without damage to. they eggs. Said tongues also yieldably resist/shocks acting axially of the eg such shocks being further cushioned by the lagers of packing 5. Iii-assembling the pac.

of excelsior 5 is rst positioned in the box 1, and the lower partition 4 is then located upon said layer.- The eggs 'are then positioned inthe openings 6 between the tongues 8. The next step is to positionthe upper partition 3 above the eggs with the upper ends of the eggs projecting vthrough the openings 6. The upper layer of excelsior' is hen positioned upon the partit1on 3, and

.Fig 3 is a view similar to Fig. 2 illus-- trating a modification;

Fig. 4 is a fragmentary plan view on a reduced scale of the egg partition, used in Fig. 5 is a similar view of anv egg parti-- tion, used in the construction shown in Fig. 6;

Fig. 6 is a view similar to Fig. 2 showing the use of two diierent egg partitions for engaging the. large and small ends of the.

Figs.. 7 8 and 9 are views similar to Figs. 2 and 6, illustrating other modiflcations.

1 represents the body of the box, and 2 a. cover fitting thereupon. The body 41 and These tongues 8, whenthe-eggs are in the I the cover 2 located on the box and secured 'by' Ia string 12 or other suitable means.

In Fig. 2, I illustrate a single horizontal series of eggs, and Fig. 3 illustrates a receptacle provided withtwo series of eggs one above the other. In both instances I employ the same construction of partition with the corresponding arrangement of excelsior or packing, and except in the particulars noted, thepackages are the same.

With -my improved construction andarrangement of parts, theeggs are securely held and protected 'from blows from any direction.

Asabove stated, the cover 2 and the body 1 provide a double .thickness of material' all around the egg space, and as the eggs are all spaced from the outer wall or walls 'of the package, such blows cannot be imparted to the eggs. The layers of excelsior or other packing protect the ends of the eggs fromv blows or jars from above or 4 ben low, and also serves the purpose of absorbing the contents of a cracked or broken egg,

hence preventing the distiguring of theV package in case a cracked eggis placed in the box through carelessness and subsequently leaks or becomes broken.

' In Fig. 6 there is illustrated a modification employing a somewhat different partition for-engaging the smaller endsl of theeggs than that which has been described. Said partition is indicated at 9 and is provided with openings 9a, through which the upper ends of the eggs project. These openings are preferably circular in form, vand around the same, the partition 'is provided with radial incisions l10 forming tongues 11. The tongues 11 are alternately left flat and bent downwardly at an angle to the partition. If the e gs are lof the ordinary size, the `downwar ly bent tongues will engage the small ends of the eggs as shown clearly in Fig. 6. If the eggs are unusually large, the flat 'tongues will be bent upwardly, as shown at thehextreme right of Fig. 6.

In vother words, while `certain ofthe tongues 11 remain straight or flat so asto more or less snugly lit the end of the egg, the alternate tongues are bent at an angle to engage the eggs at other points, and thereby provide a more secure and more resilient holding means than would be the case1 'were the tongues 11 bent at the same an e.

n Fig. 7, I illustrate a modication in which the tongues or fingers 8 of both partitions 3 and 4 project upwardly.

In Fig. 8, I illustratea Amodification in which only one partition is employed and in addition 'to the two layers of excelsior arranged respectively above and below the y eggs, a filling of sawdust lor similar granu. lar material is used between the fingers 8 of the partition.

In Fig. 9, a construction is shown em ploying a single partition as in Fig. 8, but

using only a single packing material 18,

preferably sawdust or some similar granular material.

Various slight-changes might be-made in the general form and arrangement of parts described without departing from my( inpacking, and formed with openings for engagement by the ends of the eggs, tongues being struck out of said partitions. in forming said openin s, land occupying an angu- I lar relation to t e partition to resist movel .ment of the eggs parallel to 'the partitions Aand to hold the eggslixed regardless of differences in the sizes of the eggs.

2. In a shipping case for eggs, the cornengaged, arranged between said layers of ,i

bination with a receptacle formed of card board or similar material, of layers of resilient absorbent packing material adjacent opposite walls of said receptacle, and a pairv of partitions between which the eggs areengaged, arranged between said layers of packing,and seated thereupon, said partitions being formed with 'openings for en-I gagement by the ends of the eggs, said packing primarily resisting movement of the eggs transverse to the partitions, and the partitions resisting movements of the eggs parallel thereto.

3. In a shipping case for eggs, the combination with a receptacleformed of card board or similar material, of a partition member within said receptacle formed with openings for 'engagement by the eggs .and having tongues struck out of said openings and occupying angular relation to the partition to resist movement of the eggs parallel to the partition, a layer of resilient absorbent packing material interposed`between said partition and the adjacent wall of the closure, resisting movement of the eggs toward said wall, and resilient absorbent packing material resisting movement of the eggs toward the opposing wall.

In testimony whereof I affix my signature.

CARL R. SHAFER.
