Wire can be securely Wrapped oiflfastencd to the terminals and held firmly thereon when the terminal is applied to a binding post. I v a The invention is illustrated inthe drawings, of Which- Figure 1 is a section through the terminal;

Fig. 2 is a transverse section;

Fig. 3 is a vertical section through a modified form;

Fig. 4 is a transverse section through the same form of terminal;

Fig. 5 is a section through modified form;

Fig. 6 is a section taken through another modification Fig. 7 is a perspective view of a further modification;

Fig. 8 is a section therethrough;

Fig. 9 is an elevation of a further modification; and

Fig. 10 is a section therethrough. I

The forms of the invention shown in the drawings are preferredv forms, although it is understood that other modifications'in the construction and arrangement of'the parts and in the character of the materials used i may be adopted Without departing from the spirit of the invention as set forth in the appended claims.

In generally considering this invention, the main purpose is to provide a metal terminal Which Will embrace the end of a cable a still further or stranded conductor and permit the bared ends of the Wires to be firmly and securely Wrapped around the terminal in such manner that when the terminal is connected to a 5n binding post and secured thereon the Wires will be more securely held to the terminal by reason of this connection.

In general, the invention concerns a cuplike casing adapted to embrace the end of a cable or conductor supporting a pair of spaced plates, these plates being provided vitlnsuitable, aligned apertures to-permit of receiving the stem of a binding post. The terminal is provided with openings through the end of the cuptopermit the hated ends of the Wires to be passed therethrough and Wrapped around, betweenqthe spaced plates' These plates may be provided with additional apertures for the purpose ofpassing the wires therethi'ough to niral'ce the Wrapping more secure. WVhen;

this terminal is slipped on toa binding post and the"b1nd1ng post is securely clamped down on the terminal, these spaced plates I will be pressed more closely together and thus clamp the wires more firmly therebe tween. Theplatesfm-ay be provided [with notchcs'or irregular surfaces to further 'secure the fastening of the Wires thereto.

The preferred form of the invention as shown in the drawings comprises a cupshaped metal casing 1 adapted to embrace the end 2 of a suitable conductor or cable, the ends of the Wires of Which are hatred and adapted to pass through an aperture 3 in the end of the cup. On this endzof the cup a pair of spaced plates 4 and 5 are mounted and are preferably formed integral with the cup; These plates are provided with aligned apertures 6 and 7 to receive a binding post stein, as Well as with slots 8 and 9 opening into the apertures 6 and 7. will pass up through the aperture 3 and can be Wrapped around and between theplat-es 4 and 5 to secure the conductor to the terminal. As the terminal is mounted to the stem of a binding post and the pin securely clamped down, it will be observed that it Will. be obvious that the plates 4 and 5 will be pressed closer together, thus more se cin'ely holding the wire 10 in place.

In FigsB and 4%; a modified form of the invention is shcna'n in which the cup 11 is provided with a hole 12 and spaced plates 13 andfli: having apertures 15 and 16 and auxiliary apertures 17 and 18 through which the Wires may be passed to increase the effectiveness of the engagement of the Wires with the terminal. p I

In Fig. 5 a construction somewhat similar to that illustrated in Fig. 1 is shown, with the exception that the aperture 19 leading from the cup outwardly is disposed between the two plates. This modification 1s also The wires 10 from thecondnctoi'" rather elongated, in dimensions.

' t-ions'.

that the Wire can be drawn down through this slot into the lowerslot below said aperture.

In Fig. 6 a modification is showninwhieh the plates and 21 are disposed'at an inclined angle with respect to the cup so that this terminalean be used for particular l0casimilar to'those previously described with the exception that the sides of the plates are provided with notches 22 to further insure the engagement of the wire. Furthermore, auxiliary openings 23' and 24 are provided Also, in this case, the cap is provided with two apertures 25 and 261501 the passage of the conductors therethrough. y

In themodification shown in 'Figs. 9 and lOQ-space'd plates are provided withlateral notches 27 and 28.. These plates also are formed in one piece in a U-sha p'ed manner separate from the cup, the base of the U being fastened by a rivet to the cup, this In Figs. 7 and 8 a construction is "shown whereby the'wires will be more efiectivelyclamped to a binding post.

What Ivclann 1s:- Y I I An electric terminal; comprlsing a cupheld in place as the terminal is more tightly shaped easing adapted to receive the end of a cable and having an opening in the top and provided with two spaced end parallel plates extending from the top and discon nected. r1 m'each other, the plates being provided wih registering openings for the reception of a binding screw and with slots and about which plates and between the same, bare wires from the cable are adapted to be wound and firmly clamped bet-ween the plates when said plates are drawn to-' gether by the binding screw in securing the terminal in position.
