TERMINAL.

Specification of Letters Patent.

Patented June TT, Jldtd.

Application filed January 4, 1915. Serial No. 432.

To all whom it may concern:

Be it known that I, CHAnLEs W. BECK, a citizen of the United States of America, residing at Detroit, in the county of lVayne and State of Michigan, have invented certain new and useful Improvements in Terminals, of which the following is a specification, reference being had therein to the accompanying drawings.

The invention relates to electrical terminals, and consists in the provision of a simple and efficient terminal that may be easily and quickly attached to or detached from a binding post or other member; in a construction of terminal that may be employed for engaging binding posts or other-members of various sizes, and which-when attached to the binding post or the like-will be secured thereto against accidental disengagement; in the provision of a terminal that may be readily engaged with an electrical conduit; and further, in a construction of coupler that may be easily and cheaply manufactured. The invention further resides in certain constructions, arrangements and combinations of parts as will more fully hereinafter appear. In the drawings,--

Figure l is a perspective view of a terminal embodying the invention;

Fig. 2 is a front elevation showing the terminal applied to a binding 0st;

Fig. 3 is a longitudinal, sectional view through the structure of Fig. 2;

Fig. 4 illustrates a blank from which a part of the terminal is made; and

- Fig. 5 shows the manner of attaching the terminal to the conduit and binding post.

Referrin to the one embodiment of the invention s own in the drawing, A desig nates the improved terminal composed of a member B formed of suitable metal and a clamping sleeve C made of insulating ma terial. In the structure illustrated the member B is provided with cooperating segmental portions D and E, forming in effect when engaged with the conduit, a split shank. The portions D and E are provided with threads which are engaged by the internal threads of the sleeve C, as shown in Fig. 3. The latter is preferably slightly tapered so that upon ad ustment of the sleeve C the portions D and E will be tightly clamped against the insulation of the electrical conduit F. G is the wire of the conduit F which engages a struck-up bearing portion H on the part D. The bearing H is such as to allow the end of the wire G to be inserted from the forward side thereof and then bent over the top of the bearing H, as shown in Fig. 3. The wire may then be soldered in place if desired. The member B is provided with a wide, flat portion J which when. the terminal is assembledforms an eye for engaging the binding post K or other member to which the terminal is to be attached. If the binding post K is provided with threads, the portion J may also be provided with threads complementary to the threads of the binding post.

By the arrangement just described, the memberB may be stamped from a flat blank of metal into the form shown in Fig. 4.

' When it is desired to apply the terminal to an electrical conduit, the sleeve C is first engaged with the conduit, then the wire of the electrical conduit is connected to the bearing H, as heretofore described, and the members B bent around the binding post until the portions D and E are both in engagement with the conduit F, as shown in dotted lines in Fig. 5. The sleeve C is then moved into engagement with the threads of the portions D and E. Upon screwing the sleeve upon the ortions D and E the latter willbe tightly c amped to the insulation of the conduit, and also the eye J clamped to the binding post.

From the foregoing description it will be readily apparent that the terminal is one that may be easily and cheaply manufactured, and that may be readily attached to or detached from an electrical conduit. Furthermore the terminal is clamped to the conduit and also to the binding postby the same operation.

While I have shown and described the preferred form of the invention, I do not wish to limit my protection to the particular structure illustrated, and also while I have shown the terminal as adapted for enaging abindinglpost, it may be constructed or engaging ot er members.

What I claim as my invention is:

1. A terminal-comprising a blank bent into substantially U-shapedform, the legs of the U havin segmental portions for engaging the in ator covering, of a wire and one of the legs having a struck-up hearin portion for engaging said wire, the base 0 will be.

the U forming a bearing for engaging a terminal or the like, and a sleeve engaging said segmental portions.

2. A terminal adapted to be connected to 5 an electrical conduit, comprising ablank bent into substantially LI-shaped form, the

legs of the U having segmental portions for engaging said conduit and one of the legs having a struck-up bearing portion for enw gaging the end portion of said conduit, the

base of the U forming a bearing for engaging a terminal or the like, and means for clamping said segmental portions of the leg upon said'conduit.

In testimony whereof I afix my signature M in presence of two witnesses.
