The means employed to detach-ably connect the side and end sections together in set up position is shown in Figs. 2, 3 and t, and with modifications in Figs. 6 and 13, and will now he described.

Referring first to Figs. 2, 3 and 4, it will be seen that a pair of heavy wire flocking members F are rotatably mounted, one in eachofthe endscc-tions B, andare provided with hooks 36 at their ends adapted, towengage receivingbrackets 37 on the side sections C. The members F are.alsoprorided Wlilll. V-shaped bail. portions 38, winch, when the hooks 36 are engaged in brackets 3:, are

substantially horizontal and lie directly under the cover 1). Thus it will be seen that while the hooks 36 positiyely lock the crate corners rigid they vannot be disengaged unless the bail portions 38 are swung up, and

T side and end sections, there is ofcourse nov necessity for. otherwise locking those sections. against inward 1no\e1'11e11t' when the crate is set up. In the corner look modification shown in Fig. 13 a pair of hinge butts L2 are secured one on each section and are/connected by a.removablepin43, which may also'ot coin-so be held in place in a. releasable manner by the crate cover D.

The cover is. detachably secured in place by means, the preferred form of which illustrated in Figs. 1, E2, 3 and L, while modifications thereof are illustrated in, Figs. 7 to 12, inclusive. In any event oneend ot' the cover is provided with a pair of fixed. fingers l which are arrai'iged to engage cor.

responding apertures in one end section. or i apertures 46 in one endof the base. The other end of the crate cover is proVidedwith a retractable bolt G, arranged to releasahly engage in zipertnres L7 (or, etS) in the opposite end of the crate.

The bolt G (F igs, 2, 3) is slidably secured in the member 29, andis offsetso as toconceal a compression sprint, i8 between itself and the member 30. i The top offlthe bolt is flush with the slat 29, but the latter has a depression ttlso that the finger may he used (as shown in dotted lines in Fig. to withdraw the bolt from the end section. The belt G (Figs. '2 and, 8) is slidahly nunmted in the cover, and has a convenient finger lip 50. The spring 51, in this case, merely engages the bolt to 'lrictionally hold it in either open or closed position. The bolt i (Fig. 9) also has a friction spring 553, but a leaf lHiTOI'POSQCl. between the n'ieniber :i and 52-, and has a lip to engage the rear end of the bolt in such a manner that the lip must be depressed before the bolt can be pulledbaclr. The bolt cl (Fig. 10) is slidably secured between the menlbers 29--30,

and has an integral linger {at which carries the spring which reacts with small shoulders 56 to holdiho bolt extended. The bolt (-i (liig's. 11 and IE2) whicltis releasably held in its extended p y tion by a hinge lilie dcyice 57-58.

place it will obviously prevent any Vertical l movements of the radiators in the crate, while the stops 61, 62, 65 and 66 will prevent any longitudinal play. a

In the modification shown in Figs. 17 and 18 the above mentioned stops are substituted by pairs of strips 67 which are rigidly secured to the side sections. These strips are spaced apart to form a channel to slidably receive the radiator members 59, 60 A spacing member K is now employed and consists of a transverse slat 68, which is utilized tospace the radiators from each other, and a pair of depending legs 69, which drop between the members 59 and 67 to hold the slat 68 in an upright position and also to brace or make more rigid the lower radiator.

In Figs. 14, 15 and 16 further modifications in the spacing and horizontal bracing.

are illustrated. Thus, 7 O designates a partly channeled slat, two of which support a transverse brace 71, on which is supported one end of the radiator. may be supported on a somewhat similar brace 72, which guides between strips 73,

and is preferably provided with face plates 7 1 which give a greater bearing surface on the crates and thus prevent injury to the honeycomb tubes of the radiator.

In larger types of crates it is often d-esirable to set the radiators up vertically in the crate, and in this eventit is also necessary to space them from each other to prevent injury. This spacing may be accomplished merely by a series of cross slats 75 slidably retained between guides 76 (Fig. 14). A further improved method, however,

is shown in Figs. 19 and 20, and consists in spacing the slats 75, horizontally, by blocks 77, so that the horizontal pressure from each radiator will not be imparted. to the radiators in front or behind it, but will be taken up directly by the crate. In this event also, it is desirable tospring hinge one of the upper guide members 76 as at 78, so that the strips 75 may beconveniently withdrawn or inserted, by raising the member 76 as indicated by; dotted lines in Fig. 20.
