i DEVICE FOR LIFTING Ion cans.

Application filed January 31, 1927. Serial No. 164,878.

This invention is an apparatus for handling ic'e'c'ans employed in the manufacture s; are employed immersed in brine which is cooled by means of pipes arranged in the bottom of the tank or compartment in which the brine is contained and in which a number of the sheet metal cans are arranged. these cans being filled with-the Water to be frozen. I Heretofore these cans had been lifted out by varioustypes ofbooks or grapples but it frequently happens that in. lifting these cable the grapple or hook becomes dis-con- .cted' from the can. o can usually drops and very often the eviing coils arrangedin the bottom of the tank or chamber are injured'to such an extent that the freezing fluid escapes and itis necessary to draw off the brine and likewise the freezing fluid and repair the pipes.

The. object of my invention,-therefore, is to provide a device for lifting the ice cans. preferably two at a time, which deviceshall be so constructed that when once it'i's connected to the top of the can and a pull 6X61t-.

danger of dropping the can and producing the damage heretofore referred to.

lVith this object in view my invention consists in the novel features of construction and in the manner of combining or arranging the same, all of which will be fully described hereinafter and set forth in the appended claims.

In the drawings forming a part of this specification, Fig. 1 is a view showing the practical application of my invention; Fig. 2 is a vertical sectional view partly in elevation showing one of my improved lifting bars arranged in connection with the top of an ice can; Fig. 3 is atop plan view of the same; Fig. 4: is a side elevation showing the relative positions of the various parts during the lifting operation; and Fig. 5 is a similar view showing the position to which the parts are turned when it is desired to connect or disconnect the lifting bar to the ice can.

Referring to the drawings, 10 indicates a sheet metal ice can which is rectangular in shape and in practice the upper edges of these ice cans are reinforced as indicated at 10 In the interest of speed it is desirable Then this happens to lift at least two of these cans at one time and consequently I have shown two of these cans shown side by side and in connection with each can I employ a lifting bar 11 and a connecting bar or double tree 12 for en gaging and lifting two of these bars at one and the same time, the double tree being raised and lowered by means of a cabled?) hooked to the center thereof. ,1 In the rein forced edges'of'the ice cans there areproduced oppositely disposed openings 10, these openings bein engaged by the reduced ends 14 of the bolts 14:, said bolts being arranged in the sockets l5 produced in the opposite ends of the lifting bar 16. Each bolt is projected outwardly by means. of a coil'spring 17and the in-and-out movements of thebolts; are limited by means ofthe cross pins 18 working in the-longitudinal slots l!) produced in the bolts,"the pins 18 passing transversely through the liftingarins and bolts as most clearly shown in Fig. 2.

In order to connect the lifting bar to the ice can one bolt is inserted in one opening and then the other bo'ltis retracted suilicientl-y lOPGIHllt the introduction of the reduced end into the opening in the reinforced-edge of the can. It is only necessary to have one of the boltsretractile and I have only shown one of these bolts ofsuch ,constructionbut it will, of course, be understood that if de sired both of them can be made retracti'le- Each lifting bar is formed with an upwardly extending loop 19 with which engage the hooks 20 arranged at the opposite ends of the double tree 12.

In order to steady the lifting bar while in engagement with the edges of the ice can I provide the laterally or horizontally rearwardly extending arms 21 at each end of the lifting bar and these horizontal arms are each provided'with a. curved finger or hook 22 which is brought into engagement with the edges of the can when an upward pull is exerted upon the lifting bar, the loop.

19 being so positioned with reference to the pivotal points of the bolts that these lingers or hooks 22 will remain in engagement with the upper edges of the ice can so long as an upward pull. is exerted upon the loop. This prevents the bolts becoming disconnected from the can and consequently avoids the possibility of dislocation and damages incidental thereto.

The lifting position is most clearly illustrated in Figs. 1, 2, 3 and 4 and in Fig. 5

I have shown the positions which the parts are made to assume when the devlce 1s belng disconnected from the can, the loop 19 be ing drawn down to a horizontal position and consequently the arms 21 are tilted upwardly lifting the fingers or hooks 22 away from the edge of the can and the bolt can then be Withdrawn from engagement with the opening at the edge of the can and the lifting bar removed or detached from the can.

The device herein shown can be quickly and easily attached to and detached from the ice cans and when in operation lifts the cans directly upwardly and all danger of disconnection is entirely avoided.

'I-Iaving thus described my inventioinwhat I claim is 1. In a device of the kind described, a lift ing bar provided With bolts at each end for engaging the sides of an ice can, and arms rigid With said bar and adapted to engage the edges of the ice can at points spaced from the engagement of the bolts with the sides of the can. v

2. In a device of the kind described, a lifting bar having bolts at their opposite ends for engagement with the opposite sides of an ice can, and arms rigid with the lifting bar and having hooks at their ends for engagementwith the edges of the can at points spaced from the engagement of the. bolts with the sides of thecan.

3. In a device of the kind described, a lifting bar-having means at its ends for engaging an ice can at oppositely disposed points,

said lifting bar being also provided at its ends with means for engaging the edges of the ice can at points spaced from the engagement of the bar ends with the can and whereby disengagement of the bar from the can is prevented.

at. Ina device of the kind described, alifting bar having means at its endsforengag ing the'sides of an ice can at oppositely disposed points, said bar having a loop by means of which said bar is lifted, said'bar also being provided with means at its oppositev ends for engaging the edges of the ice can at points spaced from the bar ends, said edge engaging means being so 7 arranged with reference to the lifting loop that said means are brought into engagement with the edges ofthe can when a lift-ing strain is placed upon the loop. I

5. In a device of the kind described, a lifting bar provided with bolts at its opposite ends, one of said bolts being retractile, a lifting loop and laterally extending arms each provided with hooks at its ends, said hooks being spacedv from the bolts carried at the ends of the lifting bar. a

6. In a device of the kind described, a lifting bar having bolts at its opposite ends, one of said bolts being spring actuated,'an upwardly extending loop, and hoiZontally extending arms, ach arm terminating in a hook at its end, said hooks beingadapted to engage the edges of an ice can'at points spaced from the engagement of the bolts with said can.

7. In a device of the kind described, a lift ing bar having bolts at its opposite ends, a lifting loop and steadying arms provided with hooks at their ends, the lifting loop and arms being. arranged at an angle to one another and whereby when an upward pull is exerted upon the loop the arms will be maintained. in a horizontal position.

Intestimony whereof, I hereunto afliX my signature.
