Application tiled January 28, i916. Serial No. 74,817.

To all whom t may concern:

Be it known that MINUS CARR., a citizen of the United States, residing at Maud, 1n the county of Tunica and State of Mlssissippi, have invented new and .useful Improvements in Switches, of which the iollowing is a specification.

This invention relates to a controller f or electrical ignition systems and has for its primary object to provide a controller' having the inherent property of breaking a battery circuit of the ignition system when the speed of the vehicle in case of an automobile, has reached a predetermined degree and at the same time close the magneto circuit and may also accomplish the additional advantage of rendering both the battery and magneto circuits inactive upon the speed of the vehicle reaching above a second predetermined degree.

My invention also contemplates the use of locking means for locking a portion of the device against further movement upon one operation o'f the ball governor, an object ofthe invention being the provision of two solenolds controlling the operation of an arm toward the magneto circuit closing position or a battery circuit closing position, one of the solenoidsbeing manuallycontrolled while the other solenoid is mechanically controlled, that isto say, the energization of the sole- -noid for throwing the arm toa position to close the battery circuit being manually controlled, while that solenoid moving the arm to a position to close the magneto circuit being .mechanically controlled,` the mechanism for controlling this solenoid depending for operation upon the speed of rotation of the drive shaft of the engine. .My invention also contemplates the use of auxiliary switches for rendering a portion of the governor inactive in case of rupture of a portion of the controller or the refusal to work of the magneto.

invention also makes use of means for allowing the governor to accommodate various speeds. ln order that the principles of my invention may be clearly understood I have disclosed a single type or embodiment thereof in the accompanying drawings, wherein Figure 1 is a diagrammatic view of the system. Fig. 2 is a top plan view of the solenoid control mechanism. Figs. 3 and e reach a are sectional views therethrough. Fig. 5 is a longitudinal sectional view of the governor casing, the mechanism being shown in side elevation. Figs. 6, 7, 8 and 9 are detailed sectional views through Fig. 5. Fig. 1() is a view similar to Fig. 1 showing one position of the governor and one position of the cir: cuit controlling arm, the direction of current being shown by-arrows. Fig. 11 is a sec tional View on the line 11-711 of Fig.'9.

ln the drawings, the numeral 1 designates the well'known form of magneto, the numeral 2 a self-starting motor for the internal combustion engine and the numeral 3, the ordinary dry batteries of the ignition systern.- u

In the drawings and description, I have eliminated the spark plugs and their connection as l'deem it is unnecessary in the disclosure fot' my invention.

The base l has mounted thereupon, the bearings 5, 6 and 7, the first of journaled therein, a shaft 8 having a gear connection with the shaft of the internal combustion engine with which the ignition system cooperates. rll`he shaft 8 has rigidly secured thereto a pair oi governors 10 andv 11, the latter being of a size smaller than the former, and both arranged at 90 degrees in position from each other. The governor 10 has a rotatable connection with a-collar 12 which has.

secured to rod 13 that telescopes within the shaft 8 and the hub portion of the governor 10 and the governor 11 has a similar connection 14 with a sleeve 15 slidably mounted within the bearing 6 and slidably supports the rod 13.

The sleeve 15 has encircling it between a nut 16 and the adjacent side of the bearing 6, a coiled spring 17, the purpose of which is to hold the balls of the governor 11 in a 'retracted position which results in the switch 18 that has a one end of the sleeve being normally held closed, that is to say in a closed position until the balls of the associated governor predetermined outward position, the switch 18 being mounted on a bracket 20 in spaced relation to a second switch 21, the action of which being under the control of the sliding movement of the rod 13.

To distin throughout t e remaining portion of the specification and claims, l have designated ish' between the switches pivotal connection withl the former a battery switch while the latter a magneto switch thus indicating that portion of the ignition system controlled by these switches. diate portionV of the rod 13 is a coiled spring 22 that has its opposite ends abutting an extension 23 of the bracket 20 and a nut 24 adjustable o:- the rod, the purpose of the latter being to increase the tension of .the spring at will for controlling the centrifugal action of the balls of the governor 10 for a purpose hereinafter described.

The protruding endportion of the rod 13 has secured thereto, an L-shaped finger 25, the long arm of which being movably mounted in a slot 26 formed in one end of a pawl 27 that is in turn slidably mounted in a post 28. The short arm of the linger 25 terminates in a hook 29' one face of which being arranged at an incline so` as to give a cam action to the adjacent end of a dog 30 pivoted intermediate of its ends and having its bill 31 coperating with the teeth 32 formed on the periphery of a disk 33. This disk 33 is rigidly mounted upon a shaft 34 that in turn rigidly supports a ratchet wheel 36, the teeth of which cooperate with th pawl 27 and also mounted on the shaft 34 i a circuit closing dev ic'e 37. This circuit closing device 37 has one of its'elements formed in the shape of a wheel 38, the rim of which, is made of linsulating material as well as the hub, or as illustrated in the drawings, a portion of the hub, while the spokes 39 are made of conducting material of low resistance such as copper; The other element of the circuit closing device 37 is in the form of a brush 40 so arranged `to engage the spokes as they move in a circular path.

From the description it will be seen that during the rotation of the shaft 8 through the action of the drive shaft of the internal combustion engine, the balls of the governors 1Q and 11 will be thrown outwardly and through their connections with the sleeve and rod 13, the sleeve and rod will be given a sliding movement which movement will be transmitted to the battery circuit closing switch and the magneto circuit closing switch, the former closing at a relatively slow number of revolutions orV the shaftS, while the latter closes at a relatively'higher revolution. Thus it willbe seen that initially, the battery circuit of the ignition systemis closed while subsequently, the magneto circuit is closed. or as illustrated in the drawings, partially'closed, as the circuit closing devlce 37 controls the 'closing of aportion of the magneto circuit in a mannerto be described later. Upon the rod 13 sliding a predetermined distance thefinclined face of the ii'nger 25 willdepr ss the adjacent end of the dog 30 with the result that the bill 3l is retracted from Encircling the interme.

the terminal the teeth of the disk 33. Subsequently to this action, the pawl 37 gives a partial rotation t'o the ratchet 36. This rotary action of the ratchet 36 gives a partial rotation to the wheel 38 of the circuit closing device 37, with the result that one of the spokes is brought into electrical contact with the ybrush 40 for completing the closing of the v2. Arranged in this circuit 4G between the partial circuit 45 `ind the battery 47 is a push button 48 or ther form ofmanually operated switch. Thus it will be seen that when a key is inserteid between the spring pressed contacts 44 for bridging a break in the circuit 45 at this point, and then depressing the push button 48 current will iiow from the battery 47 through the solenoid 49 and simultaneously the current will pass through the starting motor for turning over the internal combustion engine. Upon energization of the solenoid 49, its core is sucked inwardly and as this core is pivotally connected to the switch arm, the latter will be moved toward the solenoid so as to deposit one extremity upon the contact 51 forming for the wire 52 leading from the battery a. action, the remaining terminal or end of the switch arm engages the contact 52't11at is in turn connected by means of a wire 53 with an arcuate-shaped'contact54. Normally engaging'the contact- 54 is an auxiliary switch 55 the pivot of which is connected by a wire 56 leading to the battery switch controlled by the governor. The battery switch ofthe governor is connected to the magneto by wayof the conductor 57. A second solenoid4 58 is arranged in axial alinenient with 'y the solenoid 49 and has its core 59 arranged in alinement with the core 50 and attached to the switch arm at the same point. This solenoid`58 is arranged in a circuit 60 receiving current from the battery 47 u and adapted to be closed by the circuit closing device 37, when one O f the'spokes engages the brush 40 in the manner previously set forth. Upon theenergization of the solenoid 58 which takes place when the device 37 is moved by the governor, the switch arm is thrown to a position to engage a contact G1 to which is connected the wire 62 running Simultaneously with this y from the magneto 1. The switch arm 41 also engages another contact 62 that is to. A

Y operator has inserted minore joined to a second arcuate-shaped contact 53 by means of ing the contact 63 is an auxiliary switch 64 electrically connected in the magneto switch controlled by the governor by means of the conductor 65. The connection between the switch controlled by the governor and the magneto is made by means of a wire 66. In case ol"v a defect in the governor and its associate parts I provide means for short circuiting, the magneto switch and the battery switch being controlled by the governer. I accomplish this and 68 which are'engaged :by the auxiliary switches 55 and 64 when they are moved in one direction out of engagementwith the contacts 63 land 54. These contacts 67 and 68 are connected respectively-witl'i the conductors 66 and 57 tapped onto the conductors 57 and 66. l y v I will now give a brief description of the operation of my device.

In starting the system into operation, operator presses the push button. i8 with the result that current from the battery 47 passes through the motor and simultaneously through lthe solenoid 49 which energizes the solenoid, as previous to this, the a key so as to bridge the distance between the contacts 44. At

lthis point I wish it to be understood that the same key may be utilized for moving the auxiliary switches 55 and 64 to a position engaging the contacts 67 and 68 or by a separate key that lits the auxiliary switches 55 and'64, the construction oi such special key is such that the removal of the same will move the auxiliary switches 55 and 64 into engagement with contacts 63 and-,54 where-- upon the ball governors 10 and l2' will be rendered active. -It is to :be understood that the first special key does not operate both of the auxiliary switches simultaneously but separately `one at a time. zation of the solenoid 49, the switch arm is thrown into the position to throw the battery 3 incircuit for energizing the spark plugs, the current then passing through the battery switch. controlled by the governor. s the speed of the en ine increases, the battery switch 18 is bro ren by the associated overnor which may be so regulated as Ato appen .when the engine is making about 150 revolutions a minute.' As the speed of the engine continues to accelerate, the battery switch having been broken the next action will be upon the magneto switch 21. We will assume that the apparatus is regulated for stopping the engine upon reaching above 500 revolutions a minute. As soon as this speed is reached, the ated with the magneto switch moves it to open position with the result that the spark Upon the energiplugs are denergized' for cuttingoii energy' supply to the engine.
