:l(itizen of th United States, residing at
Teiarkana, in the county of Bowie and
5 Sate of Texas, have i nvente( new and use-
If ixipro oiem ents in Starters, of which the
1l owin'g is ; specification.
I\ y' invention relates to starters for in-
tern al combustion motors and has for its
10 pilinary object to provide a starter which
will not transmit the occasional backward
kick" of the motoi and resut .in 1ijera r
0 lie operator.
Atifurlther object of on ixventioni is to
15 provide means 11or locking the starter in a
inopel'ai i)e position to prevent i na'ltholrized
operatio of the inotor.
With these and other objects in view
which will be hereinafter fully described
20 and particularly pointed out in the claims,
the invention consists in ti- novel construe-
1ion and arralgemi eniti of parts illuistrated
in the accomipanying l'xravings.,fOring

ro'mally rotating in a clockwise direction
as is the 'usual practice. The tor ward end
of the crank shaft is provided with a

the clntchin ' faces of the clutch 3 fae-
in' in a counter-clockwiise direction.
Mounted on the structure of the motor is
a frame 5 comprising a rear plate 6 and
55 front plate 7, the edges of said front plate
