JOHN F. CARTER, OF GRAND RAPIDS, MICHIGAN, ASSIGNOB TO WOLVERINE STARTER COMPANY, A CORPORATION OF MICHIGAN.
STARTING MECHANISM FOR MOTORS.
Specification of Letters Patent.
Patented Nov. 14, 1916.
To all whom it may concern Be it known that I, JOHN F. CARTER, a citizen of the United States, residing at Grand Rapids, in the county of Kent and State of Michigan, have invented new and useful Improvements in Starting Mechanism for Motors, of which the following is a specification.
The present invention relates to devices known as starting mechanism for motors, as engines for automobiles, and its object is to provide a device of that character which shall be simple and economical in construction and easy of operation. This object is attained by, and the invention finds preferable embodiment in, the structure hereinafter described and illustrated by the accompanying drawings, in which Figure 1 is a top plan view of said structure; Fig. 2 is a side view thereof; Fig. 3 is a front view of the same; and Fig. 4 is a front view (enlarged) of ball-clutch members, etc.
The forward end of the engine shaft of an internal-combustion engine, as the automobile engine 1, is provided with ratchet clutch teeth 2, with which may engage corresponding teeth 3 of the alined stub shaft 4. The chauffeur by pressing the pedal 5 turns the lever 6 and slides the stub shaft axially against the pressure of its spring 7, thus operatively engaging the clutch teeth 2 and 3. He then drawsthe lever 8 whose connecting rod 9 swings thepivoted arm 10, to which is fastened a cord 11. T he cord, passing around a pulley 17, is fastened to a shaft-revolving member 12 which is in fixed relation to the teeth 3 and keyed to the stub shaft. The engine shaft is thus rotated to start the engine. The shaft revolving member is returned to its normal positionalthough the teeth 2 and 3 may still be held by the pedal in their clutching engagement by means of a spring 13 attached to a chain 14 wound on a drum 15 which is rotatable relatively to the shaft-revolving member: A suitable ball-ratchet clutch having the balls 16, intermediate the drum and the shaft-revolving member as shown, by its clutching operation thus effects the return of the shaft-revolving member by the springs' pressure.
In the construction shown, it will be seen thatthe plane in which the arm 10 swings intersects that in which the lever 8 turns,
which arrangement is more convenient and economical of space in certain automobiles: and that the connecting rod 9 is attached to said arm between its axis 18 and the point where the cord is fastened to said arm.
The parts are shown in Fig. 1 in their normal position or position of rest. It will be seen that in the illustrated construction, the cord is drawn over an arcuate portion 19 of the arm 10 when the lever 8 is moved by the chauffeur, and that the connecting rods point of pivotal connection with the arm 10, when said arm has been swung to a position at right angles to the frame 20, affords greater drawing power on the cord than when the parts are in the position shown in Fig. 1. This is desirable, inasmuch as thereby the position of the pivot 18 may be so located as to register said right-angled position of the arm 10 with the point of greatest drawing strain of the cord on the shaft-revolving member. By properly hardening and shaping (as shown) the sur faces of the shaft-revolving member 12, and the drum 15, between which surfaces the balls 16 engage, these parts 12 and 15 may be relatively rotated by an unusual force even against the clutching operation of such ballsthat is, the ball clutch may slip:
This is desirable in case of back-firing of the engine. When by such back-firing, the member 12 is violently turned backward, it strikes a stop 21 011 the frame, whereupon the engine shaft is permitted to continue its reverse movement by such slipping of the ball clutch.
The invention being intended to be defined solely by the claims, is not to be limited to or by the construction shown or described.
I claim:
1. In a device of the character described; an engine shaft; a shaft-revolving member; a cord attached to said member and adapted to rotate the same; a swinging arm to which the cord is fastened; a lever; and connection between the lever and the arm to swing the arm by the lever.
2. In a device of the character described; an engine shaft; a shaft revolving member; a cord attached to said member and adapted to rotate the same; a. swinging arm to which the cord is fastened; a lever; and connection between the lever and the arm to swing the arm by the lever, the plane in which the arm turns.
swings intersecting that in which the lever' a cord attached to said member and adapted to rotate the same; a swinging arm to which the cord is fastened and having an arcuate surface over Which the cord is drawn; a lever; and connection between the lever and the arm to swing the arm by the lever.
3. In a device of the character described; an engine shaft; a shaft-revolving member; a cord attached to said member and adapted to rotate the same; a swinging arm to which the cord is fastened; a lever; and connection between the lever and the arm to swing the my hand in presence of two subscribing witarm by the lever, said connection engaging nesses.
the arm between the arms swin ing axis 7 and the point of the cords attachment to JOHNF' CARTER the arm. Witnesses:
4. In a device of the character described;
