"My invention relates toa display ease particularly intended for containing and d1s playing vbull: oysters.-

The particularobjects of my' invention are to 'provide a" simple inexpensive case wherein bulk oysters can be kept in a sanitary condition and wherein refrigeration of the contents .can be .readily carried out; to arrange on the display case, avglass' cover through which the oysters may be readily' inspected; and to provide a case which may be easily and. quickly taken apart and' cleaned. I

'10 the above purposes my invention consists in certain novel `features of construct-ion and arrangement of parts hereinafter more fully described and claimed.

In the construction'of the shown, l designates a box-like structure preferably vformed ofvwood 'panels which are sheathed or covered .with -sheetl metal.

' Fixed on'the interior of this box or receptacle adjacent the upperendfis a pai-r of opositely disposed segmental frames2, and ormed in the central portions of the inner faces thercotarethe rectangular notches 3.

et' designates a circular Wall of reticulated material, which wall tits snugly between the l secmental frames and tortned on or fixed `to said circulaiwall, adjacent the 'upper end is apairof oppositely'dispospd lugs 5, which displayv case as' pass through the notchesA 3 whenvthe circuar Wall is positioned in the box or receptacle 1. After said Wall has'been properly seated, it is rotated a short distance in either direction, thus moving the lugs 5 into position beneath the-end portions of the frames 2,

'6 designates a sheety metal cover for lthe box orreceptacle'l. This cover is removably held on the box bymeans of hooks, .'-or like vfasteningl devices which are ivotally mounted on thesides ofthe box an enga-ge pins or projections carried by a marginal tiange 6a depending from the edge otthe cover. Formed in the center 'of the cover 6l is a. circulary opening and the edge of said cover around this o ening is flanged down- .Wardly and -inwar ly as designated by 8. 'Seated on "this vflange and fixed thereto by means ofcement r in any suitable manner is. a packing ringgt) 'of 'rubber or analogous material.`

10 designates the inner container or oyster receptacle, .which is preferably constructed of galvanized or enameled sheet met-al .which construction is especially desirable in maintaining .cleanlinessand sanitary conditions. ,This receptacle 10 is in the form of a cylinder ha ving a rounded lower end and fits snuglvwithin the reticulated Wall el.. lVhen in properposition the lower` end of this receptacle. rests upon the bottom of the box 1 and the upper end occupies a position infime diatelyl beneath the cover 5 and Jaround the flange 8 thereon.. VHandles 1l. are placed on the upper end of the recep tacle 10 to facilitate handling. I

Fixed on the rear wall of the box 1 ad-- jacent the upper end thereof is a plate 12 cally disposed cylindrical bearing 13, in the top of which is'formed avnotch lfl.

15 designates a. swinging arm which is provided with a rod or shaft 15?-, which is journaled 'in the bearino4 13, and located on the portion of said shat or rod which extends a short distance below-said hearing, is an expansive coil spring 16.

A washer 1T isloca'ted on the lower end of the shaft or rod 15 beneath the spring l() and held in-any suit-able manner. Fixed on the under sidelot the arm 15 immediately `adjacent the rodl1 is a lug 18 which norand firmly holding said wall in proper. po

and formed on or fixed thereto 'isa verti-.

mally occupies the notch 1l. rl `he bottom of the notch is rounded and the surfaces of the sides of said notch curve gradually out ward away from the center of said notch and unite with the top surface of the bearing 18 in order that the lug 18 will ride freely into and vout of said notch when the arm 15 is swung from one side to the other. rlhe forward end of the arm 15 is forked and extends over the top of the display case and carried by said forked forward endis a disk. 19 of glass or other'transparentmaaerial, which forms a closure for the opening in the top or cover 6.

When the arm 15 is in its normal position with the lug 1S in the notch 14, the transparentcover I9 fits snugly upon the packing or gasket 9, due to the pressure of the spring 16 on the rod 15aL and thus an air and dust proof joint is formed between the cover and packing rinU.`

The contents of the. receptacle 10 can be readily inspected through the transparent cover 19, and when itis desired to remove a portion of said contents, the .cover 19 is manually engaged and swung to either. side. In thus moving said cover the armI 15 swings upon ,the bearing 13 and the lug 18 rides out ofthe notch 14 onto the flat to"p\ surface of saidbearing 13. When the cover is again swung into position to close the .receptacle 1U the lug 1S will-drop into the notch- 14 by .reason of the expansive action oi. the spring 16, and thus'the cover 19 will be tightly held upon the packing ring or gasket 9. Refrigeration for the contents of the case is obtained by packing broken ice in the space outside the perforated wall 4, and thus the contents of the receptacle 10 are kept cool and in a fresh condition.

The perforated wall L prevents the broken ice from coming in'direct. contact with the .surface of the receptacle 10 and bruising or denting the same. s

When it is desired to take the case apart for the purpose of cleaning the same, the over 19 is swung around to the rear of the bon' or receptacle 1, after which the hooks 7 are disengaged to permit the sheet metal The receptacle l() is now lifted from its position Within the perforated wall et, after which said wall is partially rotated to bring the lugs 5 into position whore they can be drawn through'the notches 3 as said perforated wall is lifted from the box or receptacle.

A display case of my improved construction is very compact, is easily supplied with ice for the purpose of refrigeration, can be easily taken apart and cleaned and maintains the oysters or like commodity in a lieat, clean and sanitary condition.

I claim:

l. In a display case of the class described,

i a receptacle, a pair of arcuate framesoppositely arrarged within the receptacle, there being notches formed in the inner faces of said frames, a` perforated wall adapted to be removably positioned in the receptacle between the frames, the lower end of which perforated wall is open, and normally rests on the bottom of the receptacle, projections on opposite sides ofsaid. wall, which projections pass through the notches in the frames when the perforated wall is positioned in the receptacle, and engage beneath the frames when the wall is partially rotated in either direction, and a cover detachably arranged on the receptacle, and which cover is provided with an opening coinciding with the space Within theperfo- .rated Wall.
