is quite thin saidscrew v Application filed Augustl provemen't' in Circuit-Wire Terminals, of

which the following is a specification.

Certain for s of circuit-wire terminals heretofore ma d e consists of plates having means at one or both ends for connection therewith of one or more circuit-wires, and

having minal for connection therewith of a circuitwire' consists of a b inding-screw. which extendsthrough a screw-threadedhole in the end-portion of the plate, and as the plate has but a short bearing and easily becomes loosened. Furthermore, such a; terminal is liable to turn on its attaching-screw and thereby engage adjacent terminals or objects, causing electrical troubles, also produces a strain on the circuit-wires and their connections .with the terminal.

-This invention relates to improvements in circuit-wire terminals of this type,-and conthreaded walls thereof;

sists in providing one end-portion ofthe attacbirig-pr-rtion of the plate-with an overturned portion, and forming screw-threaded holes respectively in said overturned portion and the attaching-portion, which are ar ranged in alinement', and employing a binding-screw, 'inade; long enough to extend through. both holes and jto engage the and preferably long enough to 'projecta short distance be. low thejbottom of the attaching-portion of the plate to enter a hole in the support to which the'terminal is attached, thereby insuring a long'bearing for the binding-screw to prevent it from becoming easily loosened,

and also to preventthe. terminal from turning on the attaching-screw. As the inven tion involves essentiall one end of the plate only the other end thereof may be fprovided with any form ofcircuit-wire connection or may be devoid of a circuitwire connection.

Figure'l, is-a side elevation of a circuitwire terminal illustrating one embodiment of my invention. Fig. 2, is a plan view of the same. Fig. 3, is an enlarged sectional detail of one end-portion of the terminal.

The terminal consists of an elongated plate of any suitable length and width, but

usually made of sheet metal. It has a sub- ZrEeLnn, 5
