Referring first to Fig. 2, I have shown the present shipping case 10 in an assembled condition ready for shipping and supporting within its confines an X-ray control box or unit illustrated by the dotted line 11. The shipping case includes a lower casing member 12 and an upper casing member 13. As seen in Fig. 2, the upper casing member 13 rests above the lower casing member 12. The lower casing member 12, as seen in Figs. 2, 5 and 6, comprises generally a rectangular housing having a bottom 14, four side walls 12a, and an open top. The upper edge of each of the side walls is bent back upon itself at substantially 180 and then inwardly of the casing at right angles to the side walls for a short distance providing a horizontally extending flange 15 which extends around the inner periphery of the upper edge of lower casing member 12, as best seen in Figs. 2 and 5. A gasket 16 of sponge rubber or suitable resilient material is suitably secured to the upper surface of the flange 15 and extends completely around the flange, as seen in Fig. 6. It will be noted that the flange 15 is positioned a small vertical distance below the uppermost edge of the lower casing member 12. The bottom 14 is provided with upstanding side walls 14.: whose outer peripheral surfaces fit snugly against the inner peripheral surfaces of the lower casing side walls 12a, thereby permitting the bottom member tobe provided with depending side walls 17a which are adapted' C to be inserted within the confines of the side walls .131: of the casing.13 in a manner similar to that described in connection with the lower casing member 12. The walls 17a are secured to the inner surfaces of the side walls 13a of the upper casing 13 by anysuitablemeans such as welding or riveting. A seen in Fig. 2, the lower edge of each of the side walls 13a is bent inwardly upon itself through substantially 180 and then bent toward the interior of the casing at substantially right angles to the plane of the side walls for a short distance so as to form an inwardly extending flange 18 which extends around the innerperipheral wall of the open side of the upper casing member 13, as seen in Figs. 2, 3 and 4.

It will be notedhthat the interior peripheral dimensions of the upper casing member 13 are somewhat greater than the'outer peripheral dimensions of the lower casing It f'will be further noted that the inner lie closely adjacent the outer surface-of the side walls 12a'of the lowerf'casirig member 12 with a snug fit, as seen in Fig.2. The lower surface'of the flange 18, as seen in Fig. 2, is provided'with' a sponge rubber 'or other suitable resilient gasket 20 which extends completely T faround'the'flange,as seen'in Fig. 4.

The X-ray control unit 11 is provided with a rigidly connected base plate 21 whose outer dimensions are such 1 as topermit the base plate to be snugly received within the confines of the folded portion 22 of the side walls of the lower casing member 12 wherein marginal edge -portions ofits lower surface may rest upon the upper surface of the sponge rubber gasket 16 surroundingthe flange portion 15 in the lower casing member 12.

The method of assembling the various components of the present invention for shipping is as follows: The lower casing member 12 is placed in a position, as seen in Figs,

.t a 9,923,40b,

upper surface of the gasket 16, in a manner as heretofore described, with the main portion of the control unit extendlargerthan the control unit 11 so 'as-to permittherubber gaskets '16 and 20 to engage both the upper and lo'wer surface of the-marginal edges of the. base plate completely around' its entire periphery.

"Suitable toggle catches 25 are p rovidedbetween-the upper and lower casing members12and 13, on both the 'front'and back of the assembly, asseen in Figs.1,2, 3, -'and 7. When latched they provide a tightly closed casing for the X-raycontrol unit 11. T he toggle catches are so constructed and have their'relative partsso positioned with respect to the unit that they"are"always-under ten- *sion when in a latched'po'sition'so as to force the gasket members 20 and '16' toward? one another thereby closely embracing andcompressing the base plate between them. 'Inthis'manner, theX-ray control unit 11 is snugly sup- ,ported between resilient mountingsand is shielded within a totally enclosed stronglyconstructed shipping case so that it may beprotected'against damiage. As seen in Figs.

3' and 7, the mainbody portion of the'toggle catch in- ..cludes a link 26 and an associated lever127 secured to the outersurface of'thecasingmember 13. Hook portions 28 are secured adjacent both the upper and lower edges of the-casing member 12, as seen in Figs. 1 and 5,.so as to .permit latch engagement when the, upper andlower casing members are in shipping position, asiin Fig. 2, orare reversed with respect to each other, asinFig. 1.' The link 26is pivotally secured to the lever 27 at29'while the lever 27 is pivotally secured'to abracket 30 at 31.

Bracket 30 is rigid with casing memberlBQ 'Thetlink is placed over the book 28 and then lockedin placel-by .movement of the 'lever.27 around. pivot31 in the usual manner into the position as seen in Fig. 7.

The shipping case of Fig. 2 may be converted from its assembled position, as seenwin Fig. 2,.into-an X-ray controlunit supporting stand, as seen in Fig. 1. Referring :now to Fig. 1, it will be seen that the upper casing member 13 has been invertedfrom the position of Fig.2 insuch a manner that its closed top portion 17Inow rests upon the :ground. The relative positions of the lower casing member 12 and the control unit 11. and its associated base plate 21, as. seen in Fig. 2, remain unchanged .and. are merelypicked up as a unitand placed upon the open end of the inverted casing member-13. It will benotedlhat the bottom'14ofthe casing member 12 is constructed so as to rest upon therubbengasket 202 and within the vertically'extending flange 19 of casingmember13. It will be .noted that even in the operating position"; asseen in Fig. 1, the X-ray control'unit 11'-is supported against accidential displacement from thecasing member '12 since :the base plate .21 resides inwardlyof .the'upper edge of the casing member 12. Through the provision of this .inovel shipping case, :a :support is provided asseen in Fig. -1; wherein the X-ray control unit is positioned-at a height .for. easy access during use. Reversible handle v35 are secured to opposite sidewalls of the casing- 13'to1facilitate withstand 'severe punishmentwithout injuryto the unit contained therein. IlFWill .be further;'seen that substan- -l2- and '5 withits open end at the top; The X-ray control 7 I unit. 11 is then positioned with its -base -plate-21 upon the have to:travehundenlthe'lower-"edge oiitlre side Walls uptially 'a ll of the'ioining edgesof thenovelcoiitainer are weather-proof. ;-The bottom.14 of the lower casing member 12 and. the top 17 of the upper casing member 13 (which formsthe bottom of the support stand as seen in Fig. 1) are each provided with upstanding side wall portions which are to be disposed interiorly of the side walls of their respective casing members, so as to make it impossible for water to seep therein when used, as seen in Figs. land 2. For' waterto penetrate the join-ts between the "side walls of the casings and thelbottoms, it would first wardly between the surfaces of the-' side wallsand the upstanding walls-of the respective bottom portions and finally flow over the upper edge of the bottom portions, which is extremely unlikely. -The seal formed by the overlap-. ping outer side walls of the upper and lower casing members respectively, coupled with the tightly engaging rubber gaskets 16 and 21) foi-rn substantially 1 double weatherproofing s'eals around theadjoiningfportions of the F housing. 3

- In addition to the weather-proofingifeatures and re- "silient mounting of the control unit, the present casing is designed for. quick an'd easy assembly and disassembly.

The toggle catch permits the members tobe quicklyunlatched from one another' andchanged to their respective positions whether they-be used for the support shown in 'Fig. 1 or the closed shipping case, as seen in' Fig. 2.

In view of the foregoing description, taken inconjunc- "tion with 'theaccompanying" drawings, it is believed that a clearunderstanding 'of the construction, operation and advantages of the devicewill be'quite'apparentf to those V skilled in this'art. l
