Specification of Letters Patent.

. Patented July 22, 1919.

Application filed .Tune 20, 1918. Serial No. 241,029.

To all whom it may concern:

Be it known that I, CLYDE M. NYE, a citizen of the United States, residing at Emmett, in the county of Gem and State of 'Idaho, have invented a new and useful" Switch, of which the following is a. specification.

The subject of this invention is a switch such as is used for making and breaking an electric circuit. 7

The main object of'the invention is the provision of means for displaying a signal on an automobile when the same is to 0e reversed or backed.

Another object of the invention is the provision of means operated by the reversing lever for displaying a signa I,

- The invention also contemplates generally improving theconstruction and enhancing the utility of electric switches.

With the foregoing and other objects in view which will appear as the description proceeds, the invention resides in the combination and arrangement of parts and in the details of construction hereinafter described and claimed, it being understood that changes in the precise embodiment of the invention herein disclosed can be made within the scope of what is claimed without departing from the spirit of the invention.

A practical embodiment of the invention is shown in the accompanying drawing, 'wherein: J

Figure 1 is a view in side elevation of a sw1tch constructed in accordance with the mventlon, shown applied, the position assumed by the reversing lever when in reverse being shown in dotted lines;

Fig. 2 is an enlarged view in side eleva- 0 tion of the switch;

Fig. 3 is a plan view of the same; 'g. 4 is a rear end elevation; Fig. 5 is a fragmentary front end elevation showing the 'mountmg of the switch 4 4 elements;

Fi 6 is a diagrammatic view of the switc and its circuit.

Referring to of reference The usual plate is shown at 1, which is fastened to the floor of an automobile, as indicated, and which is suitably slotted to allow roper play of the control lever 2. Secure to the floor of the automobile; im-

' mediately in front of the plate 1, is the the drawing by numerals screws 16 or otherwise, the insula minals 17,0n the forward ends of which 0 switch which forms the subject of this invention.

The switch consists of a base plate 3, the forward end of which is upturned, as at 1. Upon this plate 3 is secured, by screws or otherwise, an arch 5 which is positioned adjacent the rear end of the plate, and which extends transversely of the plate. Secured uponthe top of the arch 5 is a horizontally disposed bar 6 which extends longitudinally of the switch structure, and which has its forward end 7 downwardly bent, and this end is positioned to the rear of and in spaced relation to the upturned end 4 of the plate' 3. The ends 4 and 7 are apertured to receive the threaded end of a horizontally disposed rod 8 which is held in place in said apertures bythe clamping nuts 8 and which also extends longitudinally of the switch. The lower end of the bent end 7 is apertured to receive thehook endmf a retractile spring 9.

' The rear end of the bar 6 is forked and the fork portions apertured to receive a pin 10' which serves to fulcrum a lever 11 on the bar. The downwardly extendin arm of .the lever 11 has the rear end of tie retractile spring 9 fastened thereto. This spring serves to draw the lower end of the lever 11 forwardly and the movement of the lower end or arm of the lever in such direction is limited by the rear end of-the rod 8, against which the'lever strikes.

Secured to the. upper arm of the lever 11 by a bolt 12 and nuts 12' which are threaded thereon, is a wedge block 13, while on the rearwardly projecting end of the bolt 12 is secured a fork 14, which is adapted to straddle the lever 2 when the lever is thrown to reverse ]position, and engage Y e t e the lever so that the ver 2 may rock lever 11 against the tension of the sp 9, and so throw the wedge block 13 forwardly to separate the resilient leaves of the switch, as will be set forth.

A support 15 is secured toand rises from [the bar 6, near the forward end of the-1781.11,

and to this support are attached, b

ter-

are the upstanding connector ends 18. The terminals 17 are of leaf formation and be-' tween these terminals and insulated from them and from the support 15 are the resilieht leaf switch members 20 which are in 0 electrical connection through strip 20. Circuit wires 19 are connected to the connector ends 18 for the purpose of conducting current from a suitable source of electrical supply to the switch.

The circuit wire 19 which leads from one terminal 17 is connected to one pole of a suitable source of electrical supply, such as the battery 21, groundedas at 22. The wire 19 connected to the other terminal 17 is grounded, as at 24, and in this, portion of the circuit are in terposed a lamp 23, which is situated at the rear end of the automobile, and the usual light circuit switch 25.

As will be understood, when the switch 25 is closed, thedevice is in condition for operation. When the lever 2 is thrown to. reverse it comes into contact with'the fork 14C and rocks the lever 11, thereby, throwing the Wedge block 13 between the forward ends of the resilient. leaf members 20, and causin them to contact the terminals 17 This wil place the terminals 17 in electrical contact through the members 20 and the bridging strip 20, and thus complete the circuit from the battery 21 through the lamp 23. This causes the lamp to light and so notifies one to the rear of the automobile that the same 1s reversed. I

Having thus described the invention, what is claimed as new and sought by Letters Patent, is z,

1. A switch, including a base plate, an

arch secured to and rising from the base 7 a bridging the other pole of which is plate, a horizontally disposed bar secured to the arch, .a lever fulcrumed at one end of the bar, a. wedge block carried b th'elever, resilient means for holding the lever in normal position, a support on the bar, terminals securedto and insulated from the support, and

resilient members separated to contact and bridge the terminals when the wedge block is swung between the members 'by' the rocking of the lever, and means for rocking the lever.

2. A. switch including a base plate having an upturned end, an arch secured to the base plate, a bar attached to the arch and having a downturned end in spaced relation to the upturned end of the base plate, arod adjustably secured to the said ends and forming a stop, a lever fulcrumed on one end of the bar, resilient means for normally holding the lever against the rod, a wedge block carried by the lever, terminals mounted on the bar and insulated therefrom and from each other, a resilient bridging member adapted for separation tocontact the terminals, and means for rocking the lever to swing the wedge block between the bridgingmember. I In testimony that I claim the foregoing as my own, I have in the presence of two Witnesses.
