rarenr-orriee CORPORATIONA CORPORATION DELAWARE BOTTOM LIFT CONTAINER Application filed August 25, 1932. Serial No. 630,475.

This invention relates to containers for container cars and to means vfor lifting the same for transfer to and from the car. More particularly the invention relates 'to containers of the crane-lift type and to improved lifting means for use in connection therewith.

Containers of this type are generally made of sheet metal and provided at the top, generally at the corners, with links or like engaging members for connection with the crane lift chains or tackle. Such containers are, therefore, lifted from the top and, in order that the lifting strains may be properly distributed, and buckling of or other damage to the container prevented, it is necessary not only to strongly brace the container but to use comparatively heavy material in its construction, so that such contain' ers are of much greater strength and weight than necessary for them to otherwise be.

The main object of the present invention is to provide novel and l improved lifting means for the container, whereby the container may be lifted from the bottom instead of from the top, thus enabling the weight of the container and its load to be sustained without throwing undue strain upon any part of the container, and thereby enabling a container for any given purpose ofv lighter weight and less cost to be produced. y

A further object ofthe invention is to provide ai simple, reliable and efficient construction of lifting means of the character and for 'the `purpose specified.

rPhe invention consists of the features'of construction, combination and arrangement of parts, hereinafter fully described and claimed, reference being had to the accompanying drawings, in which Fig. l is a top plan view of a container embodying my invention.

Referring now more particularly tothe .'-f drawings, l designates a container of that type adapted for use on container cars and which, in practice, may be made of any suitable size and of rectangular orioblong rectangular' form, a container of oblong rectangular form being shown in the present instance. The container is shownr as having side walls 2, cnd walls 3, a top wall i and a bottom wall 5. The walls 2, 3 and d and the wall 5 also, if desired, may be made of sheet metal of suitable gage or thickness. The con tainer' may be provided in practice with any suitable type of door or other closure means and may carry upon certain of its walls, asv the walls 2, guiding vand retaining shoes G i' for guiding the container into and out of a container car and holding it therein in spaced relation to adjacent containers.

Generally a container of this character is provided upon itstop wall, in the region of ts corners, with stay plates carrying links or like engaging members for connection of theV lifting chains or tackle of the crane therewith. In the present vinstance the use of such top links or engaging members is dispensed with, but the container top is provided in lieu thereof with corner stays havingl outwardly projecting portions 8 extending laterally beyond the walls and provided with grooved their lower ends, as lindicated at 10. These retainers 9 are adapted for the reception and retention in position of the four lifting chains 1l commonly employed which are united atv their upper ends by a ring or link or other 9 like element 12, whereby the lifting chains or tackle-may be connected with the crane hoist Then chains when in engagement with the container depend along the walls 3 thereof and are provided at their lower free ends with engaging hooks A13 for connection with engag-y ing links, rods or members 14 on thebase or bottom of the container, whereby the container and itsl load may be vsupported l, and lifted from its bottom instead of bein@ chain engaging ends of the hooks to lie par- 6.09 wise beheld securely by the retainers 9 from ing supported and lifted from its top, in the customary way, thereby relieving the top of the container and adjacent portions of the walls from the weight of tl c load and properly distributing the load weight and lifting strains so as to avoid any liability of buckling or other damage to the container during the lifting action. By this means the walls of the container may be made of lighter metal, and the use of wall braces wholly or largely dispensed with, enabling a container of lighter weight for any given'purpose to be made at less cost and having other resulting advantages. Y v

The engaging members 14 are preferably arranged on the inside of the container walls 3 below the bottom wall 5, which is elevated toa desired degree, thus adapting the members 14 to be placed directly beneath the bottom wall and within the bottom portion off-the .container where they will be securely housedand protected from injury. To permit of the engagement of the hooked ends of the grappling hooks 13 with the links or engaging members'. 14 the walls 3 are provided in. alinement with said engaging members 14 with openings 15 of a size to allow of the ready and convenient insertion and withdrawal :of the4 hooks. In. order to adapt the allel and snugly in contact with the walls 3 when the hooked ends of the hooks are in engagement with the engaging members 14, the body. portions of the grappling hooks are preferably made L-shaped, so that their hooked ends and chain engaging arms lie substantially at right angles to each other: This construction adapts the hooked arms of the grapplinghooks to be engaged with the inner .surfaces of the engaging members 14 andto be maintained in engagement there with as long as thechains 1.1 are in operative position and taut, while, at the same time, admitting of the ready and quick release of the hooks and chains by simply slacking the chains to a 'degree to adapt the relatively heavy or weighted chain engaging arms of the hooks to. drop by gravity down to the dotted lineposition shown in Fig. 3i, in which operationthe hooked ends of the hook` will swing` upwardly and outwardly on the engaging members 14 to a released position. This simple and effective construction and arrangement of the -engaging hooks l13 and members 14 not only ensures the proper housing of the members 14 from liability of injury, but also ensures the secure retention of the hooks in engagement with the members 14 as long as the chains yare taut, as the chains will other.

any possibility of displacement duringraisi ing,.loweringand transfer movements of the container.

It will be understood. ofcourse. that the retainers 9 and engaging members 14 may, 1f-

Y other.

desirechbe placedupon the same walls as the guide shoes 6, but are preferably placed upon the container walls at right angles to the walls bearing the guide shoes, for greater convenience in applying and removing the chains where the shoes 6 are employed to more or less narrowly space the containers from each In the present instance the retainers 9 and engaging members 14 are placed upon the fend walls of an .oblongrectangular` container which may be designed'for use, for example, in a drop side container car, so that when the drop sides are down the chains may be applied or removed with great ease and facility. The bottom-lift attachments may, however, be applied upon square containers orcon-tainers of other desired Vforms and upon ,the same walls as the guide shoesor other walls as re-. quired to suit exigencies of service.

lnorder to enable theup-per part of the container to be madev of lightweight, and to relieve the same from cushioning strains, a spreader' 1G, which iswsuitablyl supported, preferably fromthe link l12, is. provided to engage the chains 11 at la suitable levelabove the container top 4 to hold the cha-ins spread for sucha distance above the top,4 .of the container asfto maintain the chainsstraight and vertical from thelifting points upto `the spreader point, from which spreader points the chains may converge to :thelink 12. By this means the lifting pull is main, tained in straight linesy to a point sufficiently above the container to 'prevent any converging pressures from thecorners 7` toward the center line of the container which would tend to crush and cause collapse ofthecontainer at its top. Hence the container may be made of comparatively light material throughout without liability` of injuryI from lifting strains. y n

' An important advantage of this invention, in addition to those stated, isthat thebottom-lift avoids thenecessity. of employing what is knownas a c ar rider, that is` a man to ride on the crane' hook and stand onthe top of the containers to engage the .lifting chains'with the links of a ,container as usually constructed.

While the construction disclosed y is. preferred, it will, of course, be understood that changesk in the form, proportions, details of construction and 'arrangements of parts may be made within the scope ofthe appended claims, without departing from the spirit or sacrificing any of the advantages of thel in vention.
