UNITED STATES?! WILLIAM H. COLLIER, OF PAINEfiiVILLE, UHIO.

CIRCUIT-CONTROL DEVICE FOR AUTOMOBILES.

Application filed October 24, 1921. Serial No. 510,078.

To all whom it may concern:

Be it known that I, WILLIAM a citizen of the United States, and a resident of Painesville, Lake County, State of Ohio, have invented certain new and useful Improvements in Circuit-Control Devices for Automobiles, of which the following is a specification. 1

My invention relates to devices for controlling the various electric circuits with which motor vehicles, particularly passenger cars, are usually equipped for operating the lights, the starter, the i signal. The object of my invention is to provide a simple device for opening and closing these electric circuits by means of a hand-operated member conveniently located within the drivers reach.

My invention is characterized by a novel construction of switches, which lnclude a rotary switch arm for controlling some of the circuits and a separate switch arm adapted to Operate between a pair of spaced terminals-for controlling other circuits. Both switch arms are actuated by a rod or shaft mounted in the steering post of the autovehicle. A button or like member projecting out of the center of the steering wheel serves to turn the shaft for operating the rotary switch arm and to move the shaft axially for operating the other switch arm. The switches are preferably enclosed in a casing to protect them from dust, moisture and other deleterious elements.

The novel features and advantages of my invention will be understood from a detailed description of the construction illustrated in the accompanying drawings, in which- Figure 1. shows a preferred form of my new control device, certain of the arts being shown in vertical cross-section or clearness;

Fig. 2 is a transverse cross-section'on line 2-2 of Fig. 1;

Fig. 3 is a cross-section approximately on line 33 of Fig. 1; i

Fig. 4 is a detached perspective view of the spring which holds the switchoperat ing shaft in normal position axially; and

Fig. 5 is a detached pers ective view of the rotatable switch arm which controls the lighting and ignition circuits.

In Fig. 1, I have shown part of a steering wheel 1 mounted at the top of a steering post 2, the latter being shown broken away. At the lower end of the steering ;ing to the support 3.

ition and the A I post 2 is a housing or support 3 for the steer- H. COLLIER,

ing screw. These parts are of usual constructlon and require no further descrlptlon.

The support 3 carries a casing indicated as a whole by A. The casing has an extension or bracket 4 through which pass 'uitable fastening members 5 for securing I The casing in practice will preferably be Il'lFv-J. drical in shape, has a chamber e .:iosed at the bottom by a removable cover '5". In the casing A are mounted switch terminals,

usually called binding posts, to which the conductors of the various electric circuits are connected. These binding posts, which may be of any suitable construction, are shown in the form of bolts adapted to receive nuts for clamping the wire connections. This is one of the most common forms of binding post in use. The binding post 8 is for the signal or alarm circuit, which operates a suitable signal, usually a horn. The binding post 9 is in the starter circuit. The binding post 10 is in the battery circuit, or other source of electrical energy. The three binding posts 11, 12 and 13 are connected in the lighting circuits. The circuit of the headlights leads to the binding post 11; the circuit of the tail-light goes to t e binding post 12, and the circuit of the sidelights goes to the binding post 13. All of the binding posts 8 to 13 inclusive are propfrly insulated fromthe casing A by suita le insulating bushings 14,

An operating shaft or rod 15, mounted in the steering post, extends into the casing A through an opening in the to late 16 of the casing. The upper end 0 t e shaft 15 projects through the hub of the steering wheel and terminates in a knurled head or button 17 by meansof which the shaft is turned or moved up'and down, as desired. The lower end of the shaft is provided with a pair of bushings 18 of insulating material,vwhich are held in place by a nut 19, or otherwise. The bushings 18 form a'circular groove 20 for a purpose which will presently appear. The shaft 15 carries am- I tary contact member indicated as a whole by C and best shown in Fi 5. The part C, which may conveniently is stamped out of a single piece of metal, is formed with a bushing 21, a flange 21 and an extension 22, which I will call a switch arm. The..,contact member C is firmly mounted on an insulating bushing 23, in the opening of which is secured a metallic sleeve 24. The contact part C, bushing 23 and sleeve 24 are mounted as a single member upon the operatln shaft 15. Any suitable means may be use for compelling rotation of the switch arm 22 with the shaft 15, and yet permit an axial movement of the shaft in either direction relative to the contact member. conveniently be accomplished by a key or spline 25 secured to the shaft 15 and extending into a groove or slot 26 in the sleeve 24. In this way the shaft 15 may be moved up and down without disturbing the position of the switch arm 22. However, a rotary movement of the shaft is always accomplished by a corresponding rotary movement of the switch arm 22.

The axial movements of the shaft 15 0 erate a switch arm 27, which I have shown In the drawings as part of a spring member S, best illustrated in Fig. 4. The member S, which is made of spring metal having good conductivity, comprises the

arms

27 and 28, connected by a neck portion 29, The member S is secured to the binding post 10 and electrically connected thereto, but insulated from the casing A. The binding post 10 passes through a hole 29 in the neck portion 29 of the member S. It will be understood that this integral construction of the

arms

27 and 28 is here mentioned merely as a preferredform and not by way of limitation. The switch arm 27 has an opening 30 in which fit the insulating bushings 18 at their reduced or grooved portion 20, whereby the arm 27 is operatively connected to the shaft 15 and insulated therefrom. That is to say, an axial movement of the shaft 15 in either direction is accompanied by a corresponding movement of the arm 27. The engagement between the bushings 18 and the switch arm 27 is sufliciently loose to permit free rotary movement of the shaft 15. The arm 27, acting as a spring, normally holds the shaft 15 in the position shown in Fig. 1.

The spring arm 28 terminates'in a pair of curved extensions 31 arranged to engage the underside of the circular flange 21' of the contact member 0. The tension of the spring arm 28 is such that the extensions 31 yieldably press against the member C and hold the bushing 23 against the top 16 of the casing, thereby preventing axial movement of the switch arm 22 when the shaft 15 is moved up and down. The arm 28 performs the additional function of permanentl connecting the switch arm 22 with the blnding post 10 of the battery circuit.

The binding posts 11, 12 and 13 terminate at their lower ends in rounded contact heads or buttons 32 arranged to be engaged by the switch arm 22. The spring arm 28 tends to hold the switch arm 22 firmly against the heads or buttons 32.

To the binding posts 8 and 9 are connected This may contact pieces or terminals 33 and 34, respectively. These terminals, which are insulated from the casing A, may convemently be shaped as angle pieces out of sheet metal.

The free end of the switch arm 27 projects between the terminals 33 and 34. When the shaft 15 is in normal position, the free end of the arm 27 is out of cont-act with the terminals 33 and 34, as shown in Fig. 1.

When the shaft 15 is pushed down, the arm 27 engages the terminal 33 and closes the electric c1rcuit which operates the horn or whatever signal device is used on the car. As soon as the pressure on the button 17 is released, the spring arm 27 moves the shaft 15 back into normal position. When the shaft 15 is moved up by a pull on the button, the arm 27 engages the terminal 34, thus closing the starter circuit.

In the casing A is mounted a suitable switch, indicated as a whole by T. As this switch may be of any construction and does not in and of itself form part of my invention, I need not show or describe any structural details of the switch. It will be suf ficient to say that the switch T may be of a type sold in the open market as a pendant switch, in which there is a spring-pressed pin or plunger 35. The arrangement is such that when the pin 35 is pushed in, it closes the circuit and immediatel snaps back into normal position. \Vhen t e pin 35 is next pushed in, the circuit is o ened. In other words, the circuit contro led by such a switch as T is alternately closed and opened by successive operations of the pm or p unger 35. The switch T is so mounted in the casing A that the pin 35 projects in the path of movement of the switch arm 22. Consequently, when the button 17 is turned clockwise (as viewed in Fig. 2), the point 36 of the arm 22 pushes against the end of the pin 35, which is thus operated to close the c1rcuit. When the button 17 is released, the spring-pressed pin 35 pushes the arm 22 bac into normal or neutral position, as shown in Fig. 2. The switch T controls the ignition circuit of the car. In Fig. 2 I have shown an electrical connection 37 leading from the switch T through the casing A. This connection is supposed to be part of the ignition circuit. When it is desired to open the ignition circuit, it is only necessary to turn the button 17 again clockwise as faras it will go. That movement will operate the pin 35 of the switch T and open 2 the ignition circuit. The spring pressed pin 35 thus serves the double function of operating the switch T and automatically restorin the switch arm 22 to normal position a. ter each operation of the switch. The switch T is, therefore, an independent c ircuit-controlling member for the ignition circuit and remains in actuated position (either open or closed) until again acted upon by the arm 22. It will be understood any other suitable form of circuitclosing device may be used in. conjunction with the arm 22 for controlling the ignition or other circuit.

In order to close'the circuit connections through the lights, the button 17 is'turned counter-clockwise from normal position until the switch arm 22 engages one or more of the binding posts 11, 12 and 13. The arm 22 may be madewide enough to engage all three of these binding posts simultaneously, so that, when the arm is in the position indicated by the dotted line 22' in -Fig. 2, the headlights, sidelights and tail-light are all on. The arm 22 may be moved in position to engage only the contact 11 or 13 or the contacts ll and 12,- or the contacts 12 and 13. If desired, a pointer ma be attached to the u per end of the sha t 15 to indicate on a dial the particular circuit or circuits which are closed in any particular position of the shaft 15. f

I have not deemed it necessary to show the circuit connections'in which the terminals or

bindings posts

8, 9, 10, 11,- 12 and 13 and the switch T are included, because these circuits are well understood by the skilled electrician. It will be enough to say that the

insulated conducting members

27 and 28, which are permanently connected to the binding post 10 of the battery or generator circuit, form a common connection between the source of electrical energy and the circuit wires leading to the

binding posts

8, 9, 11, 12 and 13. The battery or other generator is included in the ignition circuit 37 by a suitable connection 38 between the binding post 10 and the switch T, as" shown in Fig. 2.

It will be seen from the foregoing that I have provided a circuit-controlling device of very simple construction and operation, and which consists of parts that are not easily broken or liable to get out of order. The location of the button 17 at the center of the steering wheel laces the control of the starting, lighting, signal and ignition circuits almost at the finger tips of the driver. Furthermore, the device of mfy invention is easily installed on any type 0 car equipped wlth the usual electrical circuits.
