At the other end of base I0 there is a post

permit.
While the chief use for a jack is to support the
vehicle while a tire or Wheel is being changed,
it will be readily seen that my device could be

After the wheel has been elevated and the post
is in proper position, nut 22 is released. As the
clamp formed by nut 22 and the lower end of
member I5 is opened, it slides down on wedge I8.
This provides for a gradual andaccurately con

It will be seen that post 33 is curved so that
its upper end may be properly positioned under
the brake drum while its lower end is clear of

extends materially in every horizontal direction

from the vertical that passes through the upper
end of the post where the weight of the car rests.
This insures stable equilibrium and eliminates
any danger of accidental tilting of the post.
