LIFTING AND CARRYNG DEVICE.

Application lcd June 10,

The present invention relates generally to handles for receptacles and is more especially directed to the provision of a detachable handle or bail for containers and the like, which, owing to the conditions under which they are used, do not embody handles or other forms of gripping surfaces intheir construction.

vWhile my invention has a wide range of applicabilty, I shall describe it, and the method of utilizing the same, in connection with handling containers for ice cream and similar receptacles. However, I would have it understood that this is not to be construed as a limitation of my invention, which, as will be manifest `from this disclosure, may be used in connection with vessels of different types and for various purposes. For example, containers as used in some types of ireless cookers, or tanks in cooling systems, which are generally without grips or bails, may be readily handled by means of my invention, as well as other devices to `which my invention may be conveniently applied.

As is well known, ice cream cans or containers are usually stored Within a cabinet containing a refrigerant or within which a refrigerant is circulated, the cans being set or supported in cylindrical sleeves of a diameter which provides la very small clearance between the inner walls of the sleeves and the outer walls of the cans positioned therein, this being necessary to obtain the most satisfactory results from the refrigerant. rhis small tolerance does not admit of locating a handle or other gripping surface upon the can and consequently some means must be provided for inserting the can in the sleeve or removing it therefrom. Heretofore, it has been the practice to perforate the wall of the can at diametrically opposite points adjacent its mouth, these holes being designed to receive the ends of hooks held in the hand of Vthe one n'ianipulating the cans. The cans, when filled, are bulky and heavy and the insecure gripping surface afforded by the tips or nibs of the hooks in engagement with the thin metal of the wall of the can has been pro ductive of many accidents induced generally by the wall of the can yielding under pressure, so that the hook ends become disengaged v therefrom. A greater number of accidents result in the removal of the cans from their sleeves, owing to the fact that a film of ice 1926. lSerial No. 114,912.

cans are virtually frozen to the sleeves. Manifestly, it must be possible to exert a suflicient pull in a substantially Vertical plane, to break this ice lock, and, many times, in the effort to do so, the hooks become dislodged from the can openings, by the yielding of the wall of the can, or by the bending of the hooks, or the manner in which thehooks are manipulated. This possibility will be readily apparent from the fact that the small clearance between the walls of the can and its sleeve, together with the small openings in the can, do not admit of the use of a deeply curved hook,

and, at best, the entrance ofthe hook in the can openings is limited to about one-eighth of an inch or less, sothat the supporting or bearing surface is practically negligible. As the attendant usually must assume a stance upon the top of the cabinet, in order to exert a vertical pull, to separate the can from the sleeve, it will be evident that the disengagement of the hook from the can under his effort, will have disastrous results. In fact, in man cases, serious personal injuries have followed the sudden releasing rof the hook, while property damage is common.

From the foregoing, it will be manifest that the present methods of handling containers of the types specified are extremely unsatisfactory and the general object of the present invention is to provide a means for handling ice cream cans and similar types of containers or the like, which will eliminate or overcome the disadvantages which are inherent to Such existing methods. v j

A further object of my invention is to provide a simple and economical as well as durable medium, whereby ice cream cans and other containers of the kind, may be expeditiously and safely handled with less effort than is now required.

My invention also comprehends the provision of a means for attaining the aforesaid objects which is designed andadapted for use A with many existing types of containers, and especially ice cream cans, without alteration thereof, and which may also besatisfactorily employed in conjunction with other receptacles whose walls may be perforated in the manner of ice cream cans.

More specifically, myinvention is directed to the provision of a portable or detachable yhandle orbail which may be positively ork `5sprii1gactuated into engagement with the wall of the container or the like, soV as to em-v body all of the advantages of a permanently attached handle, my invention affording a substantial and convenient gripping surface, whereby anice cream can, for instance, may be readily ,manipulated within the sleeve to separate it therefrom, and removed without distorting the wall of the can or otherwise affecting the usefulness of the same or of the sleeve.

Other objects andadvantagesflowing from the practicing of my invention will present themselves as the description proceeds, and I would have it elearl understood thatl reserve unto n'iyself all rights tothe full range ofequivalents, both in structure and in use, to which I may -be entitled under Vmy invention in its broadest aspect.

For the purposes of ,this disclosure, I have elected to ,illustrate and describe 4certain preferred embodiments vof my invention. My invention may ytake other forms however, without departing from the spirit and scope thereof, as defined by the appended claims.

ln the accompanying drawings: n

Figur-e 1 is a View, partly -in section, of a preferred embodiment of my invention, wherein the can engaging means are positively actuated into and out of engaging position.

Figure 2 is a view, similar to Figure 1, of a modified -form of my invention, -in which lthe can engaging elements are spring-actuated in one direction.

Referring now to the drawings in detail,

in which likecharacters `of reference are Vemployed to designate similar parts in the several views, and more particularly to the structure Yshown in Figure 1 the body or bearing-portion of the device is composed or two equal lengths of metal tubing 7 and T which are connected adjacent their outer ends by a preferably tubular handle or gri-p 8, which may be of the configuration shown, or of any other suitable shape. The ends Iof the grip lor handle 8 may be extruded and shaped Vto provide supporting surfaces generally conforming to the contour `of the bearing-portion, as indicated at 8a, the meeting parts being united, as by welding. course, in lieu of employing tubing for the formation of the handle or grip 8, it may be cast in vthe desired shape and suitably vjoined 4to lthe body portion, or the latter and the handle may be cast as a unit. y A

AS will be observed, the inner opposed ends of the Vtubing 7 and 7 are spaced to provide for Athe reception of a barrel 9 which is mounted upon a shaft 1 0 and locked thereto by means of a set screw 10a.

The ends of said shaft extend on each side of said barrel and are threaded, ,as indicated at 11a and 11b with right and left threads which are adapted to mesh with similar threads in the bores of the respective reciprocable elements or plungers 12 and 13. These elements or plungers are cylindrical, to conform to the bearing surfaces` afforded by the inner walls of the tubing 7 and 7e, the outer ends of said members terminating in reduced portionsor lugs 12LL and 13a which are. sized to enter the usual openings provided in the walls of the receptacles with which my invention is employed, as hereinafter described.

From the foregoing, it will be evident that as the barrel 9, which is preferably lrnurled as shown, is rotated in one or the other direction, the shaft, similarly rotating within the elements `or plungers 12 and 13, will urge them in opposite directions, rotary movement of said members or elements, in response to the torque created by the meshing of the threads being prevented by the set screws 14 anc 15 which ride within ,the slots 16 and 17 extending longitudinally of ,said elements.

As is obviousfthesc screws valso function asr stops which engage the inner ends of the slots and limit the outward movement of said members.

In use, the barrel 9 is rotated to withdraw the elements 12 and 18 sufficiently -to permit their lugs to be readily alined with the openings in the can, the rotation vof the barrel in the opposite direction expanding said elements so that the lugs will enter said openl ings with their shoulders abutting upon the inner wall of the receptacle. Thus, the wall is rigidly braced diametrically andthe respective lugs are securely restrained against displacement, irrespective of the direction of the pull upon the handle 8,. The relative positions of the can 17, its sleeve 18 and the top of the cabinet 19, are clearly shown in Figure 1. v

In the modification shown in Figure 2, the plungers 12 and 13 are formed with triggers 2O and 21, projecting through the slots 22 and 23 in the wall of the tubular body-portion of the device, the opposed ends of said plungers being shouldered, as at 24 and 25, to provide supports or seats for the expansion spring 26.- It will be apparentthat the plungers may be retracted against the tension of the spring 26 by means of the triggers, the release of the latter permitting the spring` to eirpelv the plungers into engagement with Vthe can wall.r In tl'i is form of my invention, the ends of the handle or grip 8 may be in the form of collars 27 and 28, which, when located on the bodyportion of the device and fixed thereto by the set screws 29 and 30, alsov function as stops which close the slots 22 and 23 and limit the expanding movement of the plungers.

As will be manifest from the description Aof my invention, a positive and strong interlock between the plungers 12 and 13 and the wall of the receptacle is effected, which will be maintained regardless of the leverage applied to the handle, so that the danger of the latter becoming detached from the container, with the results heretofore mentioned, is entirely eliminated.

rlhe .screw-actuated plungers are desirable Wh ere strong resistance is likely to be encountered, While the structure shovvn in Figure 2 is preferably designed for handling relatively light loads, although with a spring of the proper tension, it may be satisfactorily used for any purpose to which my invention may be applied.
