My invention relates to improvements iin.
switches of the single or plural circuit. controlt pe andlias or its primary object to g rovide a novelland'improved device of this 5 d which is especially adapted` for use in controlling the signalcircuitsl of motor ve-` hicles, althou h capableof other adaptations, as lwill be rea ily appreciated by those skilled in the art.
.- Another object of vthe linvention lresides in the revision of a switch, as characterized, which 1s very simple and inexpensive in construction, easily assembled andinstalled, and which is highly eilicient andsatisfactory in practicalV use.
The invention vfurther lcontemplates a switch construction incorporatin a` novel and improved snap action circuit closing element, which is ca able of assuming a plurality of positions or closing different circuits and which will automatically maintain itself in such position until manually released. Y A still further object of the invention is to a5 furnish a switch of this kind having anovel and improved multiple and selectively "operable circuit closing element, there being `em ployed novel guide means for directing said circuit closing element to a position to close so the respective circuits and which guide means permits universal movement of said circuit closing element.
The invention also resides in certain novelconstructions, combinations and modes of operation of the various parts.
In order that the invention may be fully understood, reference should be had to the accompanying drawings in connection with the following descriptive matter.
The drawings illustrate the now preferred .embodiment of the invention, but it is to be Figure 2 is a central longitudinal sectional view through the yswitch unit andits enclo-A sure or housin and showing the same` applied to the das board the view having been taken on the line 2-2 of -Figure 3.
Figure 3 is a longitudinal sectional view taken on the line 3-3 of Figure 2 and showo ing two additional circuit closing positions of the switch element; l
Figure 4 is a group perspective view of certain of the iixed elements of the switch disassembled;` p
Figure 5 is a cross-sectional view taken on Vthe line 5-5 of Figure 2, and
Figure 6 is a group perspective view of thermovable elements of the switch assembly. i
The various elements of the device are designated by common reference characters through-out the several figures of the drawings. Numeral 1' designates Jthe instrument board of a motor vehicle which is provided with asuitable hole to receive the cylindrical casing 2 of the switch` The casing includes a circular base plate 3 which is bolted to theinstrumentboard, as shown at A, thelinner face of the base plate being circularly cored out as at 3a to receive the cylindrical body portion`2 of the casing. The disk-like closure plate 5 for the inner end o'f the vcasing 2 is tifghtly secured in effective position by means o elongated screw shanks 6 extending there` through and through the base plate A3V-there being nuts on the ends of said screws 6, as indicated at 7, for binding the closure plate in place. t is also proper to note thatthe heads of the screws 6 are bound vagainst the 'base' plate 3 by nuts 8 which bearagainst the counter-sunk face 3* thereof.
The screws 6- serve as the supportafor can` rying the annular switch block 9, a 'guide disk 10 for the'switch operating handle 11 and the transverse supporting bar 12 which receives ther inner end of the auxiliary sup`` porting stem 13 of the circuit closing disk 14:, whichkis mounted upon the inner` end of the handle 11. It will be apparent from "the foregoing general description that the screws 6 perform a? number of very important of- The switch operating handle, previously referred to, has a knobbed linger piece 11,
remotefrom vplate 3. Thus, shoulder 15 serves as a stop to limit movement of the handle in an axial direction toward the plate 3.
The circuit closing disk 14 has a central hole tightly receiving a bushing 17 of insulating material which is -ri 'dly fitted .upon a short c lindrical -metal b ook 18,-'keyed or sweatedY upon the end of handlell. As clearly shown inthe drawings, the inner end of the member 18 projects a substantial distance beyond the insulatin bushing 17. This end of member 18 issp erical'ly cored out as at 20 to receive the ball end 13 of the supporting stem 13. The supporting stem 13 has keyed tliereon just inwardly of the ball end 13, a shoulder or enlargement 21, and it will be noted that the same has its end surface cored out or rooved, as at 22, to receive the beveled rim 23 of the socket 20. A sleeve 24 is loosely 'mounted on the supporting stem 1,3, vand between the sleeve 24and the shoulder 21 there is interposed a coil spring 25. 'This spring 25 forces the ball end 13 into the socket 20 and the sleeve 24 against the transverse supporting bar 12. It will be manifest from the foregoing description that the supporting stem 13 and opv erating rod or lever 11 will be normally maintainedl in axial alinement.' However, when the handle l1 is moved in a radial direction,- whichis to say, toward the periphery of base plate 3,-the ball joint 13, 20 will permit the members 11, 13 to be thrown out of axial alinement, although remaining in end con` tact. The spring 25 will, of course, hold the .members 11, 13 4in the position mentioned until the lever 11 is manually moved toward the dead center of the hole 3b whereupon the spring 25comes into action to complete the return .alined l sition.
. the circuit closing f members 11, 13 to their .normal The switch block9 is held in laceon screw 6 by nuts 30 on either side t ereofr-there being washers 31 of insulating material between one set of nuts and the main current carrying annulus 33, which bears against one face of .side of the annular block 9; It is understood that block 9 is of insulating material a'ndfthat thescrews 6 extend `therethrough. The device 'shown in the drawin is a vthree point switch. 4In other wor s, three circuits are adapted to be controlled by switch block 9 has itsl outer periphery and its end or side adJacent the current carrying 4 'annulus 33, notched, as indicated at 35,' to

v lus 9 having'the contacttabs 36, 36".
disk l 14. The annular ters 36, 37, 38, respectively. The straps 36, 37, 38 are thus spaced from contact with the member 33 and it will be seen that their ends are bent. inwardly and rearwardly within the annular block 9 to define tabs or contacts 36, 37, 38, respectively. The current carrying vannulus33 has inwardly projecting contact tabs 36"', 37b and38b which are disposed opposite the respective tabs 36, 37, 38, as shown, each pair of tabs 36, 36h, etc. defines a restricted, substantially V-shaped,
recess to receive the periphery of the circuit closing disk 14. Each of the contact straps 36, 37, 38 is retained in place by a binding post or screw, these being denoted by reference characters 36', y37', 38', res ctively. Wires lead from each of the bindpuei posts to the respective signals. Of course, t e battery and the signals will be grounded as usual.- The straps 36, 7, 38 and likewise the current carrying annulus 33 will preferably.
be of spring copper or some other resilient material so that theirtabs will maintain or rather resume their normal relative position upon disengagement of the circuit closing disk 14 therefrom.
-The current carrying annulus 33 has a lateral strap 49 extending around the member 9 and terminating at the opposite side thereof to receive the bindingpost l41 to* which the main current supply wire from the battery attached. As shown, strap 40 isembdded'in u notch or cut-out 43'n the peripheryof block 9. i
Nuts 44threaded on screws 6 and dispod enable the same to' he adjusted len the screws 6 soas to increase or decrease the .at opposite sides of the'supportin bar'12 wiseof compression ofthespring' 25 so that the correct degree of -compression can be secured and maintained.
The uide disk 10, which has been briefly l referre to hereinb'efore, is located at a redetermined point between the annular switch member 9, and the base plate 3 by means of 6 and dis- The operating handle 11 extends through a triangular hole 51 in diskl() and when the handle 11 is inA its vnormal position,'which is to say, in `axialrialzi'.llcmeiit with supporting stem 13,-it is in contact with the bottom wall of the triangular hole. The corner 52 of hole r51 is disposed toward the partof annu- Thus when the handle 11 is moved 1n a general rightwardly direction (Figure 1) the disk 14 will be thrown leftwardly (see dotted lines Figure 3) and the handle 11 wedged into the corner .52 of hole 51 so that disk 14 will engage the contact tabs 36, 36" to close the signal circuit, which includes` the right turn signal. By ,the same token, leftward movement of the handle 11 will cause it to -be guided into the opposite disk-ho1e corner left turn 53 to eect theengagement of circuit closing disk 14 with the contacts 37 37 b to close the signal circuit. Downward movement of the handle 11 results in its being guided into the upper or intermediate notch 54 of hole 51 and since -such notch is in a vertical plane with the contacts 1193'3'9",l
of the stop signal circuit the engagement of disk 14 with such vcontacts will be e'ected to close said circuit.
There is reat advanta e in the use of the disk 10 wit f the triangu ar hole 51 in that said holeenables the operating handle 11 to partake of a universal movement Without necessitating itsy being returned to neutral position when it is desired to move it from one circuit closing position to another. For instance, the driver ma have actuated the handle 11 to right turn position. In makingu the right turn traffic conditions may necessitate a sudden stop. This stop can be immediately indicated by simply hitting lever 11 in a general downward direction. The wall of hole 51 will guide the handle 11 into the intermediate or upper corner 54 and the stop signal circuit will be instantly closed.
An important feature of the device resides in the dat ended sleeves orstops 15, 24 which vbear against base plate 3 and supporting bar 12, respectively, normally tending to hold 'parts 11, 13 in axial alinement. When parts 11, 13 assume any of the circuit closing positions the sleeve or stop members are balanced on edge as shown.. Thus, it will be manifest that a slight knock on 11 to. start circuit closer 14 toward neutral position `will result in the pressure of the spring 25 ,forcing the flat ends of 15, 24 to seat against 3 and 12 respectively.y It willbe seen that the device is automatically brought back to a true neutral position with'll, 13 in alinement.
