8 Claims. (Cl. 153—32)
This invention relates to apparatus for repairing vehicle
frames, and more particularly to a portable frame
straightenimI apparatus adapted to be moved to the site
of a piece of wrecked heavy equipment and to be lowered
over the frame of the damaged equipment so that said
frame may be straightened by the use of the apparatus.
A main object .of the invention is to provide a novel
and rearwardly spaced from the plate 21 are the top ends
of a pair of vertical I-beams 23, 23, the lower end por
tions of said I-beams being rigidly connected by a trans
versely extending I-beam 24. As shown in FIGURES
2 and 3, the transverse lower I-beam 24 is rigidly secured,
as by welding, or the like, to the forwardly facing ?anges
of the vertical I-bearns 23, 23. Triangular gusset plates

frame of a piece of wrecked heavy equipment, such as
a large trailer or other heavy vehicle, the apparatus being
relatively simple in construction, being easy to transport
to the location where it is to be used, and being arranged

to be lowered over the frame of the damaged equipment
extend the respective vertical upstanding guide rods 27,
so that said frame may be straightened, the apparatus
27 rigidly connected to the transverse axle 28 of the truck
being relatively inexpensive to fabricate, being durable in
assembly 20. Iournaled on the ends of the ‘axle 28 are
