- My invention relates to a starter for an engine, .more particularly a gas engine and the like, characterized by the employment of a screw-shaft operated by a prime mover such as an electric 'motor and a pinion screwthreaded upon the shaft and adapted to travel longitudinally in one direction along the shaft into engagementwith the rotary member of the engine to. be started and to travel longitudinally in the opposite direction after being automatically thrown out of engagement with the engine member when the engine begins to run on itsown power.

- the object of my invention is to provide an automatic electric switch controlled by the movements of the pinion whereby after a manually operated switch is operated to start the electric motor, the movement of the pinion will cause the automatic switch to be closed and the operator thereby relieved from further operation of his switch so that only a momentary manual operation is required, and whereby also the circuit is antomatically, broken when the pinion has been retracted a predetermined distance.

- Inertia of the pinion or friction between it and the yoke 16 should prevent rotation of the pinion until it is in mesh, but a slight rotation thereof before it reaches the engine wheel is immaterial.
- the movable connector blade 14 will cooperate with the fixed contacts 13 to close the automatic switch so that the driver or operator may now release the manually operated switch, which will breakthe circuit which includes the wires 10, the other circuit now supplying the necessary current to the motor.

VINCENT BENDIX, 0E CHICAGO, ILLINOIS.
I ENGINE-STARTER.
To all whom it may concern Be it known that I, VINCENT BENDIX, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Engine-Starters, of which the following is a specification, this application being divisional of an application filed by me on December 30, 1912, Se-. rial No. 739,168.
My invention relates to a starter for an engine, .more particularly a gas engine and the like, characterized by the employment of a screw-shaft operated by a prime mover such as an electric 'motor and a pinion screwthreaded upon the shaft and adapted to travel longitudinally in one direction along the shaft into engagementwith the rotary member of the engine to. be started and to travel longitudinally in the opposite direction after being automatically thrown out of engagement with the engine member when the engine begins to run on itsown power.
The object of my invention is to provide an automatic electric switch controlled by the movements of the pinion whereby after a manually operated switch is operated to start the electric motor, the movement of the pinion will cause the automatic switch to be closed and the operator thereby relieved from further operation of his switch so that only a momentary manual operation is required, and whereby also the circuit is antomatically, broken when the pinion has been retracted a predetermined distance.
In the drawing, Figure 1 is a sectional elevation of'my device shown in connection with the wheel driven by the engine such as a fly wheel and showing my invention operating in connection with the starting mechview of a portion of the starting mechanismincluding the pinion and screw shaft and illustrating the automatic switch.
Describing the construction shown in the drawing,the engine wheel which is here intended as the fly wheel 1 of a gas engine,is provided on its periphery with teeth 2. The prime mover comprises an electric motor 3 which is here shown as having an extended armature shaft 4 which is in the plane of the engine wheel and in proximity thereto. For a portion of its length this shaft is provided with spiral or screw threads 5 with Original application filed December-30, 1912, Serial No. 739,168. Divided and this 1915. Serial No. 24,028.
application filed April 26,
which cotiperate corresponding threads in the central openin of a pinion 6 adapted to mesh with the teet 2 of the engine wheel.
The construction and arrangement of the screw shaft and pinion are such that the latter is ca able of an advance movement longitudina ly of its shaft upon the initial rotation of such shaft by the electric motor and until the consequent advancement of such pinion'brings the latter into mesh with the engine wheel, whereupon the continued rotations of the shaft rotate the pinion and therebyv rotate and drive the engine wheel.
- As soon as the engine itself starts on its own end of thescrew shaft is provided with a suitable bearing 8 in the end of any suitable support such as a bracket 9 which is here shown secured to the body of the motor.
The motor is provided with two supply circuits, one being manually operated and the o her automatically. The manually controlled circuit comprises the wires 10 and-an interposed manually operated switch shown diagrammatically at 11. In case the device is used in connection with an automobile this switch mav be placed upon the dash or elsewhere within easy reach of the driver. The automatic circuit comprises the wires 12 in which is interposed an automatlc switch including two stationary contacts 13 anda movable connector blade 14. This blade is mounted upon and carried by a which is adapted to beeng'aged by a spring catch 19 whose inner end is slightly inturned so as to .yieldingly engage said am to be advanced whenever the electric motor is operated. However, this catch device is not necessary but may, if desired, bedispensed with.
Describing the operation of my starter, the first step is the closing of the switch 11 by the driver, with the result that the motor 3 is instantly started and its armature shaft 4:, which is also the screw shaft, is rotated. The pinion 6 thereupon moves longitudinally of the shaft into mesh with the engine wheel and when it is fully in mesh, and has reached the end of the threads 5 and abuts against the shoulder 4 it will rotate in unison with the armature shaft and consequently drive or rotate the engine wheel. Inertia of the pinion or friction between it and the yoke 16 should prevent rotation of the pinion until it is in mesh, but a slight rotation thereof before it reaches the engine wheel is immaterial.
Aft-er the starting of the motor by the push button, the movable connector blade 14 will cooperate with the fixed contacts 13 to close the automatic switch so that the driver or operator may now release the manually operated switch, which will breakthe circuit which includes the wires 10, the other circuit now supplying the necessary current to the motor. This condition remains until the engine starts under its own power from the explosions, whereupon the pinion 6 will be withdrawn from mesh with.the engine wheel in the manner hereinbefore' described. At a predetermined point in this longitudinal movement of the pinion the contact between the fixed contacts 13 and movable connector blade 14 is broken and the electric motor will thereupon cease to operate. When the pinion returns to its normal posit1on the spring catch will engage the connector blade .14 and hold the pinion in retracted position.
