WILLIAM W. LEACH, OF PINELAND, TEXAS.
MECHANICAL STARTER FOR INTERNAL-COMBUSTION ENGINES.Specification of Letters Patent.
Patented Dec. 21, 1915.
Application filed September 18, 1914. Serial No. 862,279.
To all whom it may concern:
Be it known that I, WILLmi W. LEACH;
a citizen of the United States of America,
residing at Pineland, in the county of
Sabine and State of Texas, have invented
certain new and useful Improvements in
Mechanical Starters for Internal - Combus-
tion Engines, of which the following is a
specification.
This invention relates to certain new and
useful improvements in a mechanical starter
for internal combustion engines.
The primary object of the present inven-.
ti on is to rotate the crank shaft of the en-
i, gine by new and novel mechanical means of
simplified and improved construction for
the purpose of starting the motor or engine.
A further object of the invention is to
provide means that can be easily and con-
* o veniently operated at a point remote from
the engine, for instance, from the 'driver's
seat of a motor car.
Further the invention aims to provide a
starter, the parts of which are automatically
25 returned after operation to their initial po-
sition preparatory to again rotating the
crank shaft.
The above and other objects are attained
by the mechanism illustrated in the accom-
30 panying drawings, in which:
Figure 1 is a side elevation of a conven-
tional form of motor or internal combustion
engine to which the present invention is ap-
plied, the latter being shown partly in sec-
35 tion; Fig. 2 is an end elevation of Fig. 1;
Fig. 3 is a detail view partly in section of
the spring wound drum; Fig. 4 is an end
view of Fig. 3 showing the spring of the
drum; Fig. 5 is an end elevation partly in
40 section of the drum on the engine shaft;
Fig. 6 is a side elevation of the sleeve, and
connected parts that are loose on the engine
shaft; and Fig. 7 is an end view of Fig. 6.
The invention is illustrated in connection
45 with a conventional form of motor 1, having
the usual. crank shaft 2, to which latter a
drum 3 is rigidly fastened by a set screw 4.
A sleeve 5 is mounted on the shaft 2 and
has one end thereof provided with a drum
50 6 and its opposite end provided with a
ratchet wheel 7. The sleeve is rotatably
mounted upon the crank shaft 2 and .the
ratchet wheel 7 thereof is inclosed within
the drum 3. A collar 8 is rigidly fastened
55 to the crank shaft 2 and abuts the drum 6- of the sleeve to prevent endwise movement
of the sleeve on the shaft 2.
For the purpose of rotating drum 3 from
drum 6, a series of pawls 9 are arranged
around the inner circumference of the drum 60
3 and are provided with balls 10 which piv-
otally fit into sockets 11 provided therefor
in the drum 3. The pawls will, when the
drum 6 is rotated in the direction of the
arrow, engage with the teeth of the ratchet 65
wheel and rotate the crank shaft 2 through
the medium of the drum 3.
A stub shaft 12 is attached to any suit-
able support on the motor vehicle and is
located substantially as shown in Fig. 1, 70
and has a hollow sheave drum 13 rotatably
mounted thereupon as more clearly shown
in Fig. 3. In order to rotate the drum 13
a belt or strap 14 is attached, for instance
by the rivet 15, to the periphery of the drum 75
6 and is wrapped a number of turns upon
itself and around the drum 6.
A cable 16 has one end 16' fastened to
the web 17 of the drum 6 and its opposite
end 18 fastened to the flange of the drum 80
13, and is wound several times around the
periphery of the latter.
In order to return the drum 6 to normal
position after operation thereof, a clock-
like coil spring 19 is fitted in the drum. 13 85
and has one end 20 attached to the inner
circumference thereof, and the opposite end
21 attached to the stub shaft 12.
A cover 22 is fastened to the drum 3 to re-
tain the pawls 9 in their socket bearings. 90
As shown in Fig. 6, the drum 6 has its
outer side open and an end of the cable 16
passed through an opening provided there-
for in the closed side or wall 17, which cable
is knotted or otherwise provided with a pro- 95
jection that engages wall 17. This structure
allows the cable to be easily secured to drum
6 and also enables the knot to be easily ac-
cessible through or from the open side of
drum 6 should the cable break and conse- 100
quently necessary to form a new knot
thereon.
The end of the belt or strap 14 has a
handle 23 attached thereto and located in
close proximity to the driver of the vehicle 105
so as to be accessible to the driver without
his leaving his seat.
The operation of the starter is as follows:
The driver grasps the handle 23 and exerts
a pulling action thereon, thereby unwind- 1101,165,008.
