ENGINE SHIPPING CASE Filed June 19, 1944 2 sheeeizs--SheerI 2 j2me/WI Vwall lof the case-cover.

which extends the full width of the plywood casebottom 21 and is secured to the

sections

29 and 30 of' thecase-bottom by its-.outwardly directed flanges 3Ifsuitably by rivets inithe manner illustrated in Fig. 6 for the channel-member 32. The Y opposite side edges of the panelA II are-slidably received in'two other sheet Ymetal channel-

menibers

32 and 33 which extend the `full height of Ythe case-cover 26, the channellmember 32 'being disposed between the sectionsV 34 `and 35 of the one plywoodl side wall of the case-cover, and the channel-member 33 being, .disposed vbetween the

sections

36 and 31 of theiotherplywood-side The channel-

members

32 and 33 are secured by their outwardly projecting anges 3I to the adjacent wallsectio'ns by rivets 38, asmost clearly appears in Fig. 6,

Vreinforcing metal strips 39 of angular crosssection being placed overthe 'edges of the plywoodwall sections, and the rivet's'being-'passed through registering holes in thesestrips and in the plywood `and flanges, vas shown.v vIn that way there isno4 danger of the rivets splintering the plywood, the angular metal strips 39 affording the 'desired amount Vof bearing surface to disn" Vtribute the load sufllciently'to prevent splintering. .'IVlfiertopswall of thecase-coveris made in two sections like'the two side walls, as indicated at 4Il'and' 4I in Fig. 2,V anda sheet metal'channel-member42 is disposed between these sectionsfandriveted theretof'byits outwardly directed angesl, `asyindicated at 38, annular sheet ,metal strips 39 being provided VIover the edges Yof theV plywood sections 4I! and 4I, similarly as in thefother portions o f the cover.- The end Vwalls'43 and 44 ofthe case-cover 26 are also of plywood'like the rest` of the cover. It fshould be clear that when the case-cover 26 is dropped i'down over the engine, l the two-piece panel YI IY enters thechannels 32,l 33, andy 4'2 and is, therefore, interlocked along allV four edges" with the case-cover 26 and case-bottom 21, inasmuch lower'niain panel section lI2 has apairlof brace rods 45Y disposed diagonally between `the caselmo'ttonuandY the' paneland bolted 'to' the casef bottomv at 46 and tothe panel sectionV I2 at 41,

whereby to lgive thefdesired rigidity to the panel v.

section I2Vforl support of the engine 'when the kcase-cover is notlin placeV over'i'the engine and fastened to the case-bottom. 7VAnother pair of brace rods 43 extend-s diagonally between the being bolted Vto the bottom 21 by the vrsame'bol'ts v46 used in'connection with'thebracerods 45 and Ybeing secured Yto the support Y23 by other cause any enlargement of the bolt holes, a1- though it will, of course, be clear that due to the interlocked relationship of the two-piece panel I I and the case-cover 26 and bottom 21, the bolts 46 are not called upon to assume'any great load YA'in the shipment of an engine.

The brace rods 45 yand 48 being all disposed in acute angular re- `lationship to the side walls oi the case and in 'acute angular relationship to one another, as clearly appearsin Fig. 2,7instead of in parallel relationship, give compound reinforcement to the engine mounting. These

rods

45 and 43 are furthermore disposed most advantageously with relation to the engine 1, so that maximum working clearance is left on both sides of the'engine, which, of course, is of advantage both in packing and unpacking.

When the case-cover'is slipped down over the engine, it may be fastened at the bottom to the case-bottom 21 along all four sides thereof, there being hollow sheet metal frame members 52 of square cross-section, as shown in Fig. 5, permanently securedto the edges of

theV plywood piecesV

29 and 30 by their inwardly 'projecting anges 53, as by means of rivets 38 entered through sheet metal strips 39 of angulaif form, similarly as in Fig. 6.' The' other flange removal andreplacementof the ease-cover; The 2;'

YThe side and end walls, it should` be clear from Fig; 2, are secured together at the corners Iby Vsheet metal frame. members' 52a. of Vsimilar form to the frame members 52, but all of these corners are riveted together, and the same is true `in regard to the top corners where frame members 52b of similar formare provided, yas indicated in'Fig. Y1, thereibeing no necessity for detachable connections. atV any of these corners, and, hence, no necessity for the use of screws.
