To all whom t 'may concern.: A

'Be it known that I, STEVEN KoBzY, a former subject of the Emperor of Hungary (who have declared my intention of be- States), and a resident of the city of Chicago, county of Cook, and State of Illinois, have invented certain new and useful Improvements in Electric Switches, of which the following 1s a specification.

My inventionrelates to improvements in electric switches, and has for its object the provision of an improved construction ot this character, whereby one switch may be readily utilized for `controlling a plurality of electric circuits. l

Other objects. will appear hereinafter.

, The invention consists in the combinations and arrangements of parts-hereinafter described and claimed.

The invention'will'be best understood by reference to thev accompanying drawings `forming a part of this specicaton, and in which- Fig. 1, is a side view of an electric switch embodying the invention and shownin positionv of use. l

Fig. 2, a top plan view of the same shown partially in section,

Fig. 3, an enlarged top plan view of a switch detached and with the enclosing casing removed, and Fig)l 4, a longitudinal section of said switc 'and having a casing 6 of sheet metal itted.

The preferred form of'. construction, as illustrated in lthe drawings, comprises `a suitable base block 5 of insulating material and secured thereto. The casing 6 is provided at each side with perforatedears 7, securedfto a supporting bracket 8,which in turn is securedvto the steering post 9 of van automobile, said bracket carrying a contact `rscrew `10by means @of which the samel iselectrically connected or grounded on said steeringv post, as best indicated in Fig ,1..j2.

A'vertic'al metallic post or stem 11 is swivel'ed` centrallyon the base 5 and is provided free passageof said stem.

at itsbottom lwithf-aA head` 12 engaging against the under side of ametallic Contact plate 13 securedrin the bottom of'block' 5, said platefbeing perforated to permit of the i The VAplate 13 is in turnjconnected with al ,to which an electric feed Wire 15.4 is connect-` of insulating material bile. served that depression of the switchfarml, i

binding postl 114i` switch. A metallic switch arm or plate 16 is pivotally connected with the upper end of the stem 1 1, said stem being bifurcated for the purpose and a cotter pin being passed horizontally through said stem and switch arm as shown. A bearing washer 17 is slidably mounted pression spring 18 is imprisoned between said washer and the base block 5, said spring serving to hold said switch arm 16 normally elevated-and at the same time insuring good electrical contact between said stem and the plate 13. A t its outer end the switch arm 16 is provided with a handle 19 operating through a substantially T-shaped slot 20 in the wall of the casing 6, andwhereby the switch arm 16 may be readily swung vertically or laterally from side to side. j y

A metallic contact plate 21 is arranged Within the casing 6 on top ofthe base 5 and' is provided with a suitable binding post 21 to which is connected a lead wire 22 for supplying current to anelectrical appliance, such as the tail light of an automobile. The plate 21 carries a springvleaf contact 23 positioned under the central position of the switch arm 16 and cooperating'with a companion spring leaf contact 24 ona metallic plate 25 secured to the'base 5, as shown. The plate 25 is post 26 to which a lead wire 27 is connected and which leads to an such as an arm of a signal for anautomo- By this arrangement, itv .will be obwhen in central position, will cause said switch arm to the spring contacts 2 3. y and 211, thus closing the circuits Vand supplying current through the wires 22 and-27. -j y .f

A metallic spring contact leaf 28 is also mounted on the base' in electrical connection'with the binding post 21 and in position to operativelyengage the base 'of a signal light 29 mounted in a suitable socket in the ktop of the casing 6, said light being ground- 'ed `through said casing in the usual way and whereby when the current is supplied to the contact 21 in any way, the light 29 will be operated to'indicate to the driver of the automobile that the switch is in ,proper working order and also to Ienable him to see that on the stem 11 and a comprovided with a bindingv electrical appliance pass-between and become fric! lt-ionall'y engaged and V.held by i the switch has been properly manipulated.

Another metallic plate is also electrically connected with the contact 21, said plate 30- to which is connected a leaf- The arrangement is such that when the switch arm 16 is swung laterally to one side or thebther, it passes between the contacts 31 and 33 or the- contacts 32 and 36 and is held therebypthus placing one pair or the other'of said contactsin electrical connection'withthe switch arni 16 and consequently with the feed wire 15. In either position o't the'switch arm,l current will be supplied to the corresponding lead wire 35 or 38 as the case' mayy be and also to lead 4wire 22 and thelight 29.

- either of the three operative positions of the switch arm, the lead wire 22 and the light 29 will be supplied with current concurrentlyT with the lead wires 27 35 and 38, as the case may be. In this way, the various circuits adapted for o eration of asignal at the rear of an automo ile maybe convenientlyT and eiiiciently controlled by the' manipulation of a sin le switch which is of simple'fconstructlon and capable of economical production.

W'hile I have illustrated and described the preferred form of construction for carryin my invention into eiect, this is capa le of variation and modificationwithout departing from the spirit of the invention. I therefore, do not wishA to be limited to the precise details of the construction set "forth, but desire to avail myself of such vaating against contact 36 provided withto `another electrical a-pplance such as a signal arm of an automobile.

It will `thus be seen that in 'Lacasse riations and modifications. as come within the scope of the appended claims.

Having described my invention, what l claim as new and desire to secure by Letters Patent is:

l 1. An electric switch comprising a base; a stem swivelled in said base; a switch arm pivotally connected with said stem; a bearing washer slidable on said stem' and opersaid switch arm; a compression spring imprisoned between said bearing washer and said base and arranged to hold said switch in open circuit position; and lelectric contacts arranged to be engaged by lateral and verticalswinging of said switch arm, substantially as described.

2. An electric-switch comprising a base of insulating material; a casing secured to said base; a vertical metallic stem swiveled in said base; a binding :post having electrical connection with said stem; a metallic switch arm pivotally connected with the upper end of said stem, said stem being bifurcated and said switch arm being pivoted on a horizontal axis in said bifurcation; a bearing washer slidable on said stem and bearing against the under side of said switch arm; a compression spring imprisoned between said bearing washer and said base; a handle of insulating material on the outer end o said switch arm, there being a substantially T- shaped slot in said casing, through which said handle projects; central contacts arranged to be engaged by depression of said switch arm, when in central position; and lateral contacts arranged central position arranged to be engaged by thel lateral swinging of said switch arm, substantially as described.

In testimony whereof I have signed my naine to this specification in the presence ci' two subscribing witnesses.

STEVEN KoBZY.
