The curvature of each supporting member 9 may take the form of a cam, or of an arc closely approximating to aquadrant, in order that the curved suring movements upon the ground.

The outer extremities ofthe curved mem- I bers 9are bent inwardlyin order to-be secured by bolts 10 to the/side members 1 of thefframe, and the inner extremities of the curved portions ofthe members are bent upwardly to provide straight portions 9 which are secured by bolts 10 to theframe mem-,

A pair of legs 19 are secured'to the inclined stays 13 to enable the frame and its load to be rigidly supported in the horizontal position,as shown in Figs. .1 and If ole desired, legs or props 19 may be hinged to the front of the lifting frame to furnish additional supports for the load when elevated. 20. is a frame which pivots upon a cross bar 21 secured to the side members 1, and to which frame adog or hooked member 22 is adjustably bolted in order to grip the flanged endofthe oil drum, and to assist in securing the drum to the lifting frame the length "adjustment of the said hooked member 'per mitting it to be emjployedon drums ,of-different diameters. I In 5 the oil drum A is shown retained upon the lifting frame by means of a pair of chains 23, and wherein one end of. each chain is attached to an eye bolt 24, secured to. one of the side members of the lifting frame, the free end of the chain after passing about the drum being inserted and retained in' a sloted bracket 25, secured to the other side member of the frame. If desired the travelling wheels 18 may be dispensed with, when transportation of'the drum is not required, and infFigs. 5,6 and 7 the frame is shown with the wheels removed therefrom; Also in Fig. ifladj ustment bolt holes. 4 are shown formed in the side members 1 of the lifting frame to enable the positions of the concave bars to be adjusted relatively to the ribs a on the oil drums.

- In Fig. 8, the lifting frame is shown in'its vertical position and against a packing case tachably secured by bolts 28 to the frontends of the side members 1. The lip is employed to slide or to be passed underneath the hotthe lifting frame to support the weight of the case. When not required the lip 26 and the supporting brackets may be detached from the; frame by removing the bolts 28.

Chains 29 are also employed to secure the packing case to thelifting frame, said. c i being furnished with gripping hooks 30 which are used to retain the case to the frame. 'In operating the device, the lifting frame is brought into a vertical position and against the upended oil drum, packing case or load, as shown in Figs. 3 or 8, whereupon-the load is secured to the frame by the means hereinbe= fore described. The operator then grasps the handles 5, and exerts a downward and backward. pressure thereon, and if necessary, and in order to obtain additional leverage, stands; or exerts foot pressure upononeof the cross barsll, or upon the axle 17.' Y

A Whentilted approximately intostheposr tion indicated in; Fig. 4:,andf owing to, the rolling contact of thecurved members 9 upon the ground, comparatively little continued-pressureupon thehandles 5 is required to raise-the load by bringing the'loadedi frame into the position shown in Fig. 5 part ofthe weight ofthe load also acting as a counter balance to bring the frame into such position. The weight of the loaded frame is'then tranferred from thecurvedmembers 9 to the wheels 8- if a wheeledframe is empl'oyed' thusenabl-ingthe load to be transported as required. The loaded frame is finallyf'brought to-rest upon the front legs 19, or' upon the latter and the rear legs 19 enabling the oil drum, if such constitutes the load, to be conveniently decanted, Y
