This invention relates to a hoist or lift adapted
construction and combinations of parts, herein
after more fully described and pointed out in
the claims, it being undertood that changes may
be made in the construction and arrangement of
parts without departing from the spirit of the
particularly for use in the handling of motor ve

The repair of a motor vehicle radiator of
necessity involves the total or partial immersion
thereof in water vats for the purpose of testing
the radiator for leaks; many such immersions
are required for the repair of a single radiator.
It will be appreciated that during the course of a

arms being welded at I‘! to the jacket in spaced
relation and being extended downwardly at a
steep incline from the side wall of the jacket.
The arms iii are parallel and at their lower ends
are made rigid by welds !8 with a vertically po
post 34, thus to give the head 36 universal move
ment upon the end of the post.
The following characteristics with respect to
the clamp are worthy of note. The clamp is
adapted to grip radiators of any size or thickness,
by reason of the length of the yoke, and adjust
ability of the clamping heads toward and away
from each other. Any radiator so gripped,
meanwhile, is almost fully exposed for making
accessible to the workman any portion thereof

on which repair work is to be done. The spacing
of the arms 23 is such that interference with tools
being used, etc., is held to a. minimum.

of the device, the universal mounting of one of

to the same diameter as plate Hi. This arrange

surface formations of a particular radiator.

opening formed in a bearing plate 28 extending
Then, additionally, the radiator is supported for
swivelling movement in a horizontal plane by
reason. of the rotative mounting of the clamping
heads upon the posts, 3| and 34 respectively.
Thus, to sum up the several operating charac
teristics or features of the lift in respect to the
handling of a supported radiator, it may be noted
that the radiator is lifted or lowered vertically
through a substantial distance, by actuation of
