Fig. 15 is a similar view of the second modification.

Referring to the drawings illustrating the first modification, 1 indicates the bottom member of an insulating base preferably in the form of` adisk, having formed in its top surface a shallow recess or depression 2 having the general configuration of an arrow head, in the center of which is a second depression 3, which is generally rectangular, in which is secured a stationary contact plate 5 provided with depressions 6, one of which is centrally disposed and one each disposed in each of the corners of the substantially rectangular plate 5, said plate having an arm 7, preferably embedded in the base 1 and extending toward the periphery of the disk, the outer end of the arm 7 being engaged by a terminal stud or screw 53 adapted to be connected to a wire or conductor leading to the horn or other audible signal.

About the periphery of the base member 1 is disposed a series of openings 10, 11, 12, 13, 14, 15 and 16 and two diametrical opposite openings 19, the first of which is designed to receive the binding post 53 and the series 11 to 16 forming the passages for the conductor wires from the various fixed contacts, to be hereinafter described, and the openings 19 adapted to receive the screws by means of which the upper insulating member of the base is secured to the lower member 1, and both members are secured to the automobile.

The upper member of the base 3O'isl a disk of insulating material, having a central, generally rectangular opening 32 and provided on its upper face with spacmgbosses 31. Adjacent the central opening 32 are two parallel spaced slots 33 through which project the bent ends of a conductor strip 34,. which is fastened to the base by a stud or'binding post 35, which constitutes the battery terminal of the switch, the bent ends of the conductor 34 passing through the slots 33 for engagement with: a sliding contact plate, to be hereinafter described.

Near the periphery of the disk 30, there is provided a series of openings 10', 11, 12 13. 14', 15 and 16 and two openings 19 corresponding to the openings in the bottom member 1, the opening 10 passing or permitting the passage of the terminal binding post and the openings 11 to 16 registering with the openings. 11 to 16 in the bottom plate and permitting passage of the various conductor wires of the light circuits.

Disposed in substantially triangular arrangement about the center of the disk 3() are three openings 39, 43, 51, and a fourth opening 47 is located in substantially axial alignment with the center and the opening 43 and between the latter and the periphery of the disk, said openings being adapted to permit the hemispherical bosses on the ends of the spring contact members to pass therethrough and project within the recess 2 in the top of the bottom member 1, in position to be engaged by the sliding contact plate to be hereinafter described. The spring contacts are disposed in convenient relation, preferably that shown in Fig. 4, the contact 36 being secured to the top of the disk 30 by a set screw 37, which also constitutes a terminal for the conductor wire leading to the bright lights, the free end of the spring conductor 36 h aving secured thereto a generally hemispherical boss 38, which projects through the opening 39. Spring contact 41 is similarly secured to the base by a set screw 40, which constitutes a terminal connector for the lead to the tail light and the boss 42 on the end thereof projects through the opening 43 in the disk. Spring Contact 45 is secured to the base by screw 44, which constitutes the binding post for connection with the wire leading to the dim lights and the boss 46 on the end. of the contact 45 projects through the opening 47. Spring contact 49 is connected to the base by screw 48, which is connected to the side lights and the boss 50 on the end of said spring contact projects through the opening 51 in the disk 30. By reference to Figs. 4 and 8, it will be seen that the wire from the binding post 53 passes through the registering openings 11 and 11 in the upper and lower members 3() and 1 of the base, the lead from binding post 40 passes through the registering openings 12 and 12, that frombnding post 44 passes through the registering openings 13 and 13, that from binding post 48 passes through registering openings 14 and 14, and that from binding post 37 through registering openings 16 and 16, while the lead: from terminal 35 passes through registering openings 15 and 15.

Sildably mounted in the recess 2 in the bottom member 1 of the base is a contact plate 60 of the general form illustrated in Fig. 7, comprising an end portion 61 generally triangular in shape having lateral portions 62 and63 extending beyond the body, the end portion 61 having formed therein an enlarged circular opening 64 and the opposite end being provided with an elongated slot 65 through which passes the binding post 35, which, as explained, constitutes the battery terminal of the switch, said binding post serving as a pivot about which theV plate 60 may be oscillated or'slid in the recess 2 of the base member l. Projecting from the center of the sliding plate 60 is a sleeve 66, which is screw threaded on its outer end and is provided with a flange or shoulder` 67 intermediate its ends.

Enclosing the base members 1 and 30 is a casing 7 0 having an open bottom and a top provided with an enlarged circular opening 71 through which the sleeve 66 projects.

Mounted on the top of the casing is a circular plate 72 of insulating material having a centrally disposed upwardly extending threaded flange 73, the plate 72 and flange 7 3 constituting the base member of the cap of a circuit closer of the push button type, the other member of the cap being a collar 7 4 of insulating material having the usual projecting flange at its top to retain the metal lined button 75, which is adapted to be depressed to close the circuit to the horn or other audible signal. The cap of the push button or circuit closer is secured to the sleeve 66 of the sliding switch plate 60 by means of a. nut 68, which engages the outer screw threaded end of the sleeve and serves to lock the plate 72 of the cap in engagement with the flange 67 on the sleeve, as illustrated in 6, so that the plate 60 will partake of any normal sliding movements of the cap of the push button or circuit closer.

Slidably mounted within the sleeve 66 is a tubular member 77, which is provided with an integral double bend flange 76, which serves as a support for a helical spring 82, the lower portion of which bears on the flange and the upper portion engages the interior ci" the button 75 and normally holds the latter in its outer position. Fixed within the tubular member 77 is an insulating sleeve 78, in which is secured a metal pin 79 having a rounded lower head 80, which is fitted with an insulating ring 81, the sleeve 78 and the ring 81 serving to insulate the pin from the adjacent metallic parts. Spring 82 also exercises a yielding downward stress on sleeve 78 and the parts carried thereby.

The upper or outer end of the pin 79 projects slightly beyond the insulating sleeve 78 in a. position to be engaged by the member 75 of the push button, when said member is depressed against the tension of the spring, thereby completing the electric circuit to the horn or audible signal device.

The top of the casing is preferably provided with suitably inscribed legends indicating the particular lights which will be energized when the sliding push button is moved in a given direction. These legends appear in the drawings as Side, All, Brt and Dim, indicating that the lights named will be on, when the push button has been moved on the casing toward the particular index. Surrounding the central opening in the casing is another special index marking, which is preferably in the form of an annulus 72 of contrasting color, which is normally obscured by the base plate 72 of the push buttens, but which isr uncovered in part when the vpush but-ton is moved laterally in any direction. In order to'- render this index marina-g visible, it is preferably white and a portion of the same will appear'l as a white' crescent whenever the push button has been mor/ed to close any vof the light circuits. 1When all of the light circuits are onen and push button. is in neutral or centra-l position, this annular band of contrasting color will be completely obscured.

The operation ofthe switch is diagrammatically eXempliied in Fig. 14 considered in connection with Fig; 5. When the slid- Y ing Contact plate 60 isv in the position indicated: in dotted lines in Fig. 14, all of the circuits to the various lights are broken, as said contact is out of engagement with all of the contacts 381, 42, 46 and 50, the battery 140 is, however, permanently connected to the sliding contact plate 60 by lead 141, contact screw 35 and the Contact bar 34, so that the circuit to the audible signal may be closed at all times by depressi-ng the member of f the push button, thereby completing the circuit to battery 140, lead 141, terminal 35, contact bar 34, sliding Contact plate 60, sleeve 66', spring 82, push button 75, pin 79, fixed contact plate 5, conductor 7, terminal 53, lead 142, horn 143, to the ground and back to the grounded side of the battery. In order to energize the bright lights and the tail light, the sliding contact plate 60 is moved downward from the position shown in Fig. 14, by slid-ing the push button toward the designation Brt, as shown in Fig; l, thereby causing the sliding contact plate 60 to pivot on the binding post 35 and move into engagement with the contact 38. rThis movement also carries the hole 64 out of registry with he Contact 42' and causes the latter to engage the Contact plate 60, thereby establishing a circuit from the battery through the bright lights as follows: Battery 140, lead 141 to contact plate 60, as before, contact 38, lead 144 to the bright lights, thence by way of the ground connections back to the battery. The circuit from the battery to the tail light is, battery to plate 60, as before, contact 42, lead 150, tail light 151 to ground. If it is desired to use the side lights, together with the tail light, the sliding contact plate 60 is swung upward from the position shown in Fig.v 14 to engage contact 50 and also to engage Contact 42' of the tail light. rifhe cir cuit will then be from the battery to the contact plate 60, as before, contact 50, lead 148 to side lights 149 to the ground back to battery and the tail; light circuit will as hereinbefore described. If it is desired to use the bright, side and tail lights simultaneously, the contact plate 60 is slid to the right by moving the push button in the direction of the legendV All, thereby bringing the sliding; contact plate intol engagement with the contacts 38, 50 and 42, which completes the circuits hereinbefore described to the bright and side lights and also tov the tail light. Then the dim lights are desired, the sliding contact plate 60 is moved to the left, as shown in Fig. 14,. by sliding the push button toward the legend Dim, as indicated in Fig. 1,. which causes the contact plate to engage contacts 46 and 42, so that the circuit to the dim lights will be from the battery, lead 141 to contact plate 60, before, contact 46, lead 146, dim lights 147 and ground back to battery.. As the contact plate 60 is also in engagement with contact 42, the tail light. will be energized. It will thus be seen that, by the proper sliding adjustment of the push button, the bright and side lights may be energized independently or simultaneously or the dim lights may be energized, under all' of' which conditions the tail light will also be ener-v gized and the sliding contact plate 60 will be held in any of its adjusted positions by the convex head of the pin 79 engaging the corresponding depression 6 in the fixed contact plate 5. It will also be seen that the horn or audible signal may be operated for any and all positions of the push button, as the pin 7 9 associated therewith-is always inengagement with the contact plate 5, which is directly connected in the horn circuit, as hereinbefore described.

The switch is adapted to be mounted on the steering post or other suitable location on an automobile and the various wiring connections are taken in through the registering openings in theupper and lower members of the base. The device, therefore, not only involves simplicity and facility in control of the various lights and the audible signal', but lends itself to ready application to various types of steering wheels employed in automobiles, on which the usual type of push button for controlling the horn or au dible signal is mounted, as the switch may be substituted for the push button.

In the modification shown in Figs. 10 to 13, the same general characteristics of operation are involved and the device differs from that heretofore described in structural details only. The base comprises a bottom member 100, which is provided with a countersunk Contact plate having the same type of depressions 106 as the fixed contact plate 5 in the first modification, which contact plate is connected to terminal nut 108 by metallic strip 107, the nut being engaged by a screw or binding post 103. Let into the top surface of the bottom member 100 is a conductor ring 109, which is in electrical connection with terminal nut or socket 110, which is engaged by a screw or binding post 110', which constitutes the terminal for the tail light connection.

The upper member 130 of the base is separated from the lower member by spacer lugs or walls on the latter, not shown, in order to provide a free space between the members. The upper member has an enlarged central opening similar to that in the preceding modification, which opening is surrounded by a countersunk conductor plate 133, on the lower face of the member, which is similarly apertured and is connected by conductor strip 134 to terminal nut or socket 135, in which is mounted the set screw or binding post 135', which constitutes the terminal of the lead to the battery. Concentric with the plate 133 are two arcuate conductor strips 136, 138, which are countersunk in the lower face of the upper base member, as indicated in Figs. 10 and 13 and are connected to terminal nuts or sockets 137 and 139, respectively, which are engaged by screws or binding posts 137 and 139', which constitute the terminals for the bright and side light wires from the switch. Midway between the ends of the arcuate strips 136 and 138 is a contact 140, which is also countersunk or recessed into the lower face of the base member 130 and is connected with a terminal nut or socket 141, which is engaged by screw or binding post 141', which constitutes the terminal connection for the lead to the dim lights. As a matter of convenience in making the wiring connections, the upper base member 130 is provided with a peripheral depression 131, through which the various binding posts pass and both of the members 100 and 130 are provided with aligning openings near the peripheral edges thereof, through which the conductor wires are led and in which the .screws for connecting the base members engage, in substantially the same manner and form shown in the preceding modification. The base members are enclosed in a casing 170, similar, in all respects, to the casing shown in the first modification, having a central opening corresponding with the opening in the upper member 130 of the base and slidably mounted on the casing is a push button similar to that hereinbefore described, including abase plate 172 having a vertically threaded flange 173, which is engaged by cap 174, which retains the button or finger piece 175, which is held in its outward position by a helical spring 182.

The push button is locked to a sliding member 160, which is of inverted cup shape and lies within the space between the upper and lower base members. Extending from the center of the member 160 is a sleeve 166, which is locked to the base member 172 of the push button by a nut similar to that in the preceding modification. A metallic sleeve 177 fits within the sleeve 166 and is provided with a flange 176, which forms the lower abutment for the spring 182. Within the sleeve 17 7 is an insulating sleeve 178 and mounted within the latter is a pin 179 similar, in all respects, to the pin 79 in the preceding modification,

the'lower end 180 of which is rounded and is adapted to engage the several depressions 106 in the fixed contact plate 105 to hold the switch ,in its various positions of adjustments and also to form a connecting element in the circuit between the push button and horn. Closely surrounding the sliding member 160 is a helical spring 161, which is of substantially the same diameter as the fixed contact plate 133 and is, therefore, sufficiently large to engage the plate 133 and any of the other fixed contacts 136, 138 and 140, as the push button is adjusted to its various positions for energizing the bright lights with the tail light, the side lights with the tail light, both the bright lights and the side lights with the tail light, or the dim light with the tail light, and also to engage the conductor ring 109 in the bottom member of the base to complete the tail light circuit simultaneously with the closing of the circuits to any and all of the other lights.

The operation of this modification is practically the same as that in the first form of the device and will be understood from the diagram shown in Fig. 15. When the push button is in central or neutral position, all of the light circuits are open, as the sliding iember 160 and the spring carried thereby is in central position and, therefore, out of engagement with all of the stationary contacts in the lighting circuits. As in the case of the first modification, the pin 179 connected with the push button is continuously in engagement with the fixed contact plate 105, so that the circuit to the horn can be closed in any and all positions of adjustment of the switch. When the push button is moved to bring the sliding spring contact 161 into engagement with fixed contact 136, the circuitV to the bright lights is closed as follows: Battery 140', lead 141, binding post 135', conductor 134 to fixed contact plate 133, spring 161 to fixed contact 136, binding post 137', lead 144', lamps 145' to ground. At the same time, the circuit to the tail light is closed by the engagement of the spring contact 161 with fixed contact ring 109, the circuit being completed through binding post 110', lead 150 through the rear or tail light 151' to ground. When the sliding contact is moved by the push button to engage fixed contact 138, the circuit is closed through the side lights 149 as follows: Battery 140', lead 141, binding post 135'. conductor 134, fixed contact plate 133, spring contact 161, fixed contact 138, binding post 139', lead 148', through the side lamp 149 to the ground. l/hen the push button and the sliding spring contact are moved to the right, in the a1'- rangement of the apparatus as shown in Fig. 15, the spring contact 161 engages both fixed contacts 136 and 138 and the parallel circuits are closed through the bright lights, the side lights and the tail light, said circuits being i' lead 146 through the dim lamps 147 to the ground.

`Both` forms of the invention as described, therefore admit of the selective control of the lights and the operation of the aiulible signal by the manipulation of the push button. /Vhen the latter is in central or neutral position, `all of the lighting circuits are interrupted, but, by sliding adjustment of the push button to `the various positions herein- -2"() before indicatedfthe circuits to the bright 'lights :andthe tail light, the circuits to the bright lights, the side lights and the tail light,.or the circuits to the dim lights and the tail light, respectively, may be closed.

"275 In :addition tothe legends on the top of the casing of the switch to indicate which of the light circuits are closed, a'further indication is aiforded b the uncovering of a portion of the annular .and 72 of contrasting color by '3b the base plate of the push button, the particular position of the crescent-shaped section ofthe band which is exposed indicating not only that some of the lights are on, but the ,g particular light circuits which/are closed by 5535 the switch."
