slots 24, which lie nearest the shafts 10 and
18 serve to prevent spring 29 from mesh-
ing the gears too tight. A separating
shield 30 is mounted for pivotal movement
5 upon the shaft 23 by means of arms 31 ex-
tending downwardly on either side of the
gear 28 engaging said shaft with journals
between the respective arms of the yoke 25
and the gear 28. A lug 32 is formed upon
10 the separating shield 30, and a pair of stops
33 are formed on the rear plate 6 and are
disposed in the path of movement of the lug
32 to limit the movement of the shield 30 in
both directions. A pawl 33 is pivotally
15 mounted upon the shield 30 and is adapted
to engage the teeth of the gear 28, and is so
disposed that when the gear 28 rotates in
a clockwise direction the gear will rotate the
shield through the medium of the pawl. A
20 flat spring 34 has its one end secured upon
the shield 30 and engages the pawl 33 with
its other end and hold the pawl in engage-
mnent with the teeth of the gear 28. A
tongue 35 is formed upon the shield 30 and
25 is adapted to pass between the gear 28 and
the gears 20 and 21 to support the same
against the influence of the spring 29 when
the gear 28 is rotated in a clockwise direc-
tion and the shield is moved thereby through
30 the medim of the pawl 33, as hereinbefore
described. A coil spring 35' has its one end
connected to the shield 30 and its other end
connected to the rear plate 0, and serves
to normally position the tongue of the shield
35 out of engagement with the gear, said lug
32 to respective stop 33 serving to prevent
said spring from moving the shield too far.
It will be noted from the above descrip-
tion, that the shield 30 is held in an in-
40 operative position when the gears 20 and
21 are rotated in a clockwise direction and
the gear 28 rotates in a counter-clockwise
direction. However, when the gears 20 and
21 rotate in a counter-clockwise direction
45 and the gear 28 rotates in a clockwise di-
rection the pawl 33 engages the teeth of
the gear 28 and the shield is moved there-
with in a clockwise direction whereby the
tongue 35 is driven in between the gear 28
5o and the gears 20 and 21, and the gear 28
is moved out of engagement with the gears
20 and 21 against the influence of the spring
29. As soon as the gears are separated the
gear 28 stops rotating the gears 20 and 21
55 slip over the surface of the tongue 35, the
friction of said gears 20 and 21 serving to
hold the lug 32 against the respective stop
33, against the influence of spring 35'.
When the mechanism is in this position the
60 gears 20 and 21 are out of driving connec-
tion with each other, see Fig. 4. Thus it
will be seen that while the gears 20 and 21
are rotated in a clockwise direction a driving
connection may be maintained therebetween.
whereas, when the gears 20 and 21 are ro-tated in a counter-clockwise direction the
shield 30 breaks the driving connection be-
tween the gears 20 and 21, and prevents the
shaft 10 from rotating the shaft 18 in a
counter-clockwise direction, as would be the 70.
case if the motor 1 kicked back while it was
being cranked.
The rod 26 extends some distance beyond
the hole 27 and has a pivot stud 36 mounted
near the outer end thereof. A cam lever 75
37 is pivoted upon said stud at a point in-
termediate its ends and has a cam surface
38 formed at one end thereof, which en-
gages the outer surface of the frame adja-
cent the hole 7 when the cam lever is actu- 80
cted to withdraw the rod out of the hole.
A transverse hole 29 is formed in the rod
27 at the outer end thereof, andti hole 40
is formed in the cain lever 37 which is
adapted to register with said hole 39 when 85
the cam lever is positioned to hold said rod
in its retracted positIon. When in this po-
sition the hasp 41 of an ordinary padlock
42 may be inserted in said holes to lock the
rod in its retracted position. When the rod 00:
27 is in a retracted position the gear 28 is
i; ithdrawn from engagement with the gears
20 and 21, the gears 20 and 21 are out of
driving connection with each other. Thus-
it will be seen, that by locking the rod 27 95
in its retracted position the starter may be
rendered inoperative to prevent unauthor-
ized operation of the motor.
Having thus fully described my inven-
tion, I claim:- 1001
1. In a device of the character described,
the combination with a gear mounted for
rotation, a second gear mounted for rota-
tion and lateral movement and adapted to
mesh with said first mentioned gear, a 105,
spring adapted to normally hold said sec-
end gear in meshed engagement -with said
first mentioned gear, a separating shie.d
adapted to pass between said gears and to
move said second gear out of mesh w ith 110'
said first mentioned gear, and a pawl mount-
ed on said shield and engaging one of said
gears to move said shield between said gears
when said gears are rotated in one direction.
2. In a device of the character described, 115
the combination with a gear mounted for
rotation, a second gear mounted for rota-
tion and lateral movement and adapted to
mesh with said first mentioned gear, a
spring adapted to normally hold said second 120
gear in meshed engagement with said first
mentioned gear, a separating shield adapted
to pass between said gears and to move said
second gear out of mesh with said first men-
tioned gear, a pawl mounted on said shield 126
and engaging one of said gears to move said
shields between said gears when said gears
are rotated in one direction, a lug on said
shield, a pair of stationary stops disposed
in the path of said lugs to limit the move- 130
