I JOHN V. SOHAFER, a tates, residing at Marietta, in the vcounty of Washington and State of Ohio, have invented new and useful Be it known that Improvements in Switches, ofwhich the fol# 1- thus closing a number of circuits and belowing is a specification.

This invention relates to an electric switch and has for` its primary object to provide a switch capable of lclosin a plurality ofcircuits upon simple operation thereof.

An object of the invention is to provide .a switch of substantiaf construction consist'- ing of fewv parts the movable member of| which may be mechanically supported in any of its adjusted positions.

With these and other objects in view the4 invention will be better understood from the following detailed description taken in connection with the accompanying drawing wherein;

Figure l is a sectional view through the switch. r n

' Fig. 2 is a detailed View showing one position ofthe blade. f

Fig. 3 is a top plan view -with the top removed.

Fig. 4' is a diagrammatic view showing one use of my improved switch.'

of the switch My invention consists of a metallic base 1 supported in any suitable form ofv Casing 2. To this base is connected a bindlng screw 3 to which one terminal of a circuit is conf l nected. Spaced from the base .is a plurality of contacts 4 each associated with a binding screwI 5. These contacts are provided with hook shaped extremities 6 fora purpose j hereinafter described.

Embracing the base 1, but disconnected therefrom, is a substantially inverted U shaped blade '7 to the'h'orizontal portion of which is connected the handle 8 projecting eXteriorly 4of the casing. Each of the arms 9 and'. 10 of the bladeare bent in a manner to allow a rocking movement of the blade J upon the base and further provided with curved extremities 11 adapted to engage with the extremities 6 of thecontacts and in this particular showing the blade 7 -is of a width great enough to c onneet the contacts in pairs as clearly shown 1n Fig. 3. Intermediate of the length of the arms `9 and 10, I provide openings 12 of a size to engage portions of the surface of the balls 13 slidably7 mounted in an opening 14 in the base. These/ballsare normally forced into engagement with the openings/12 by a coil spring 15.y

From the foregoing descriptionit will be seen that in a very simple manner the blade may be rocked for electrically connecting` pairs of contacts together and with the baose sides the arrangement of the balls 13 are such that the blade 7 will'be held in any of its adjusted positions. One use" of my s'witchis clearly shown in Fig. 4, wherein the switch is capable of closing the lamp cir-` cuits of an automobile or other vehicle. One :terminal of the battery 16 is connected by the condhctor 17 'to a strip 18 that connects one contact of each pair together.- VAt this pointI wishfto call attention to the fact that in certain uses of the switch the strip 18 will bedispensed with. The remaining contact of one pair is connected by a conductor 19 to the conductor 17 whilethe remaining contact ofthe other pair is connected by a conductor 20 to the conductor 17. Arranged .in

the conductor 19 are the head lights 21 while arranged in the conductor 20 are the side-lights' or other .suitablel auX- iliary lights" 22. The tail-light 23 and `'dash-lights'2l1 arearranged in the 'conductor 17. Thus it will be seen that when theswitch'is thrown to a position as shown in Fig. 2 the head lights, tail lights and dash lights or other suitable lights are illuminated while the l/remaining lights are^ illuminated when the switch is thrown into its Iother position. It is of course tol be understood that the invention may be con- :structed in various lother manners than that shown. It is my intention by the following claims to fully protect the novel manner of connecting the switch blade to the base 1 so that the sa e may assume a plurality of positions and connect the contacts in pairs, therefore I do not wish to be limited in the exact showing except as set forth in the appended claims.

Having described my invention, what` I claim is;

1. In an electric switch, al metallic base, a i

blade of substantially inverted U-shape straddling the 4base and fitting snugly over the same, and contact members positioned at opposite sides of the base and insulated therefrom, said blades being tiltably mounted on the base so as to move either 'arm of the blade, optionally, into contact with the adjacent contact member, the other i thereof, and ContactI members at sides of and' insulated from the base, said positioned to contact with arm of the blade being in contact lwith the base.

2. In an electric switch, .a metallic base, a blade of substantiallyinverted U-shape straddling the base, contact members positioned at opposite sides of the base. and

insulated therefrom, said blade being tiltvably`mounted on the base so as to move either arm of the blade, optionally, into contact with the adjacent contact member, the other arm of the blade being moved into contact with the base, and means for holding said blade in adjustment. In an electric switch, a metallic base, a blade of substantially inverted `lJ-shape straddling the base and fitting snugly about the upper portionthereof, the lower portions of the arms of said blade in either direction upon the Lbase transversely opposite members being the adjacent arm of the blade when said blade is tilted into operative position.

4. In an electric switch, a metallic base, a

substantially U-shaped blade member strad- .dling the base and being tiltably mounted thereon for movement transversely of the base,v said blade member being movable vertically of the base in either direction, the arms of the blade member being provided 'at their lower ends with outwardly projecting contact elements, and Contact members mounted at opposite sides of and insulated from the base,

transversely of the blade extending loutwardly to permit tiltinor said contact members being provided with contact elements ward the base and positioned over the contact elements of the arms of the blade member.

5. In an electric switch, a metallic base, a blade member including two arms `eXtending downward along the sides of the base,

said 3member being tiltably mounted upon the base for movement in either direction thereof, and contact members adjacent to the sides of and insulated from the base, said members being so positioned as to contact with the adjacent arm of the blade member when said member is tilted into operative position uponthe base.

6; In 'an electric switch, a metallic base provided with a transverse bore, a substantially inverted `U-shaped blade member straddling said base and having the lower portions ofits arms bent outwardly, locking balls mounted in said bore, an eXpanprojecting inwardly; to-V arms of the blade member being provided with openings for reception of theballs positioned to'hold the said member in lowered position while permitting tilting thereof transversely lof the base, and contact members/mounted adjacent to the sides of and insulated from the base member, said contact members having elements projecting abovethe lower ends of the arms of said blade member.v 4

In testimony whereof I aflix my signature.

JOHN VINCENT SCHAFER.
