:ELECTRIC SWITCH.

fsrEcInIcATroN forming part of Letters Patent No. 738,969, dtedseptember i5, 1903.

Application filed May 19,1903. Serial No. 157.839. (No model.)

To @ZZ whom t may concern,.-

Beit knownthat I, BENTON W.WOLDRIDGE, a citizen of the United States, residing at Trenton, in the county of Grundy and State of Missouri, have invented certain new and useful Improvements in Electric Switches; and I do declare the following to be a full, clear', and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification. c

This invention relates to new and useful improvements in electric switches comprising a device adapted for connection with a telephone or telegraph line and so arranged that in case of an electrical storm the telephone connection may be broken, thus preventing damage to the instrument from direct contact with the line-wires.

The invention consists, further, in various details of construction and combinations and arrangements of parts, which will be hereinafter fully described, and then specifically dened in the appended claims.

My invention is illustrated in the accompanying'drawings, in whieh- Figure l is a perspective view showing my device as connected to a line and telephone V wire, and Fig. 2 is a detail view showing the device actuated so as to allow the telephonewire to be disconnected.

Reference now being had' to the details of the drawings by letter, A designates a bar which carries insulators B, to which a bar O, having slotted ends,is held by means of staples D. A rod F has one end bent at right angles, as at F', with an eye G in the end thereof, to which a cord I-I is connected, while the lower end of the rod, which is journaled in an aperture in the lower angled end of the staple-carrying rod, is bent to form a hook K at right angles to the length of the rod.l

N designates a rod which is pivoted at N' to the arms of the forked end of the staplecarrying rod, and the pivotal end of said rod is formed into a cam, and said rod N is adapted to engage a slot or recess in the lower angled end of the staple-carrying bar, while a portion of said rod intermediate its pivotal and free `gage the eye S of a telephone-wire S.

ends is bent to form a loop M, adapted to en- Said cam is provided for Vthe purpose of bearing with sufficient frictional force against the rod F to hold the same from accidental displacement, but allowing the rod F to turn when the cord H is pulled upon.

In setting up my improved lightning-arrester the bar-carrying insulators are adapted to be fastened at any suitable location, preferably to the electric pole, and the telephonewire SQ which is detachably held to the pivotal rod, is adapted for connection with an instrument in a house. In connecting up the `telephone-wire with the rod the eye of the telephone-wire is connected to the loop in said pivotalrod, and the latter is held in a vertical position by means of the hook at the lower end of the rod, which is journaled to have a Arocking motion in the angled ends of the staple carrying bar. In this position the telephone-wire is in direct electrical contact with the wire T, which connects with the main line-wire, said wire T being connected to a lug upon the staple -carrying bar, as shown. When it is desired to disconnect the telephone-wire from the main line, the operator merely has to pull upon the string which is connected to the hooked rod, causing the same to make a partial rotation sufficient to free the end thereof from the pivotal rod, and as the pivotal rod is pulled out by the wire S', which may be slightly under tension, the

eye of the telephone-wire is allowed to fall by gravity off the free end of the pivotal rod, and electrical connections will be broken and any damage to the telephone avoided which would otherwise occur from the overcharged wires.

While I have shown a particular construction of apparatus embodying my invention, it will be understood that I may make various changes in the detailed construction of the same without departing from the spirit of the invention.

Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-

1. An electric switch comprising a block having insulators thereon, a bar mounted upon said insulators, and having connection with a line-wire, a pivotal rod mounted upon IOO said bar, and a lock member carried by said bar and having a hook at one end adapted to hold the free end of said pivotal rod, a telephone line-Wire having a loop at one end adapted to engage said pivotal rod, and means for disconnecting said pivotal rod, as set forth.

2. An electric switch comprising a block,in sulators carried by the latter, a bar fastened to said insulators, said bar having its ends bent at angles to its body portion, a pivotal rod mounted upon one of the angled ends of said bar, a lock-rod having a hooked end pivotally mounted in an angled portion of said bar and adapted to engage and hold the pivotal rod, the latter provided with aloop adapt- I 5 ed to receive an eye in the end of atelephone line-wire, as shown and described.

In testimony whereof I hereunto aiiix my signature in presence of the Witnesses.

. BENTON W. VVOLDRIDGE.
