Spring Lifters, of which the. following is-a,
specification;
This, inventions relates to, an. improved.
10 valve spring, liter' espeially designed'for
use in connetion- with internal 'nomibustion
engines and' has as. its. primary object; t
provide a device ofthis. character which
may be readily engaged with the engine.
15 and operated to lift; anyone of the intake
or- exhaust valve springs thereof and then,
adjusted for rigidly holding the said spring,
in elevated, position[ so; that the-:retaining
pin. or.other anchor'for the said.spring rnay,
20 be readily attached. to or detached from the
stem of the valve:
The invention has as. a further object to
provider a device, of the above described.
characters employing a. main lever jaw.
25 adapted to. engage. the valve spring with
the lever of-the jaw, operakle for lifting the
spring, and.I to further provide a second jaw
adjustable upon the nin.jaw for support-
ing the main jaw to. hold 'the spring ele-
30 vated..
A further object of- the; invention is. to
provide, means- upon the main, jaw of the
device for' automatically-.lcking the sup-
porting jaw at adjustment with respect to
35 the main' jaw.,
And the invention. has as a still further
object to provide an.arrangement wherein-
the lever for the.main jpa N'will7 be formed
by a handle which may-rbe detached- from.
40 the said- jaw so-thatinany instance where:
the presence of the handle 'would hamper
the operation of coinedting the pin with
the valve, stem or displacing the, said pin,
the said .handle:.maybe;readilyremoved.
