W.H. FARMER. ELECTRIC SWITCH. APPLICATION men :uLv 22, 1915.

Pafntd 0613.12, 1915.

v LE-. i

member which is designated by the numeral 32 is lformed of brass and has projecting or depending `therefrom a screw threaded'portion 33 which is adapted to engage the screw threads of the integral nut formed beneath the recess in the` insulator block. It will be noted that the connecting member has formed thereon an enlarged portion designated by the numeral 32 intermediate its ends, and this enlarged portion is adapted to move freely in the recess 2 of the insulator block upon coactionl between the threaded portion 33 of the said Amember and the nut 3 below said recess for a purpose to be hereinafter more fully described.A

It will be obvious vthat when the parts of this device are assembled as shown in Figs. l and 5 of the drawings, the current will be fed to one of the conductors through one of the wires which may be designated by the numeral 20, and upon the insertion of the movable member in the recess 2 between the said conductors 5, the contact will be formed therebetween and the circuit will be completed between the wire and the wire 21.

,This connection is controlled by` means of the movable member having its lower end 33 operatively engaging lthel screw threads 4 on thenut 3 which is positioned below the recess 2 in the insulator block, whereby upon rotation of the said member by means of the handle 3l, the enlarged portion 32 of the said member will be brought into and out of contact with the spaced ends of the conductors which are positioned in the said re'- cess. All that is necessary to operate this switch is to rotate the said member as above described to form a connection between said conductors, and this member will always be in position to make a safe and sure, and

water proof contact therebetween.

This switchis adapted to be set up between the batteries and engine, current from the batteries entering the switch on one of the wires as hereinbefore described, and is carried therethrough to the other wire. This switch is operated by simply turning the movable member which is positioned in the recess in said insulating wire which easily @epics of this patent may be obtained for five cents each, by

of some insulating I`na` .terial, and the lower portion of the said messes and simply makesor breaks the connection between the saidV wires. It will be noted that in this switch the ends of the wires go straight in theendsof theinsulator'block, and are firmly and securely held Herein, which is an improvement over devices where the wire has to be wound around a pin or lug, whereby they are veryliable to annoying breakages. Furthermore, the movable connecting member of this switch is formed in one piece whereby vwhen the engine is not in use, said member" may be removed, and thus render the same worthless for further usel until it is replaced, which would prevent anyone disturbing the engine during temporary absence of the op` erator.

- From the foregoing description of the construction of mv improved switch, ,the manner of applying the same to use, and the op eration thereof will be readily understood, and it will be seen that I have provided a simple, inexpensive, and elicient means for carrying out the objects of this invention.

claim:y v

A switch comprisinga one piece linsulator block having a centrally disposed recess with a countersunk internally threaded portion therein, said block having a pair of diametrically extending passages from the recess to the ends of the block and a pair of vertically extendingl passages bisecting each of the first mentioned passages, conductors positioned in the diametrically extending passages projecting in spaced relation in the recess, said conductors having openings therethrough alined with the vertical passages and sockets in their outer ends to re-A WILLIAM iii.
