CONNECTION-TERMINAL FOR ELEQTRIO CONDUCTORS.

Specification of Letters Patent.

Application filed April 26, 1906. Serial No. 313,868.

To all whom it may concern."

Be it known that I, HERBERT G. ADDIE, a citizen of the United States ofAmerica, re-' siding at Cresco, in the county of Howard and State of Iowa, have invented a new and useful Connection-Terminal for Electrical Conductors, of which the following is a specification, reference being had'to the accompanying drawings, illustrating same My invention relates to connection terminals for connecting electrical conductors, to be used in various places, as, for instance, on electrical condensers, distributing strips, or wherever such terminals are required.

- The principal objects of my invention are to provide a terminal which does away with screw, bolt, or pin fastenings; to provide a terminal whichmay accommodate a conductor leading out of an inclosed portion and at the same time seal the inclosed pOrtionperfectly air or moisture tight; to provide improved means for insulating such a terminal from conducting parts to which it is mounted; and to provide simplicity, durability, and accessibility in such a terminal connector.

It is 'enerally customary tomount such terminal s by the use of screws or bolts, and with the terminals generally in use it is very hard to seal the aperture through which electrical conductorsextend from an inclosure to the termmal, as in a condenser, wlthout going to extra trouble and expense, and then generally the sealing of the aperture is not perfect.

The terminal of my present invention has a hollow portion through which an electrical conductor may extend and be soldered thereto so that the solder completely seals up the hollow portion, the latter also serving as a rivet to secure the terminal in place. Thus it will be seen that this terminal, made of a single piece of metal, serves as a connection terminal for electrical conductors and also as a means for mounting itself and sealing up the aperture through which a conductor may extend from the interior of an inolosure Referring to the accompanying drawings illustrating the preferred form of -my invention, Figures 1 and 2 are side elevations of the connection terminal of the invention. Fig. 3 shows an insulating washer. Fig. 4

' shows a cross-section of the terminal riveted in place to a piece of sheet metal and suitably insulated therefrom. Fig. 5 is a bottom end view of Fig-1. Fig. 6 is a bottom view of- Fig. 4, showing how the terminal is riveted in place. Fig. 7 is a side elevation of a condenser provided with the terminals of my invention. Fig. 8 is a top view of Fig.7. Fig. 9 is a front elevation of a distributing strip showing a modified form of terminal connector. Fig. 10 is an edge elevation of Fig. 9. Fig. '11 is an end view of Fig. 9.

The terminal of Figs. 1 and 2 preferablycomprises a metal strip 1. provided with a portion 2 bent at right angles thereto, a part of the metal of portion 2 being drawn outinto a thimble 3 which is preferably scarred on the inside as shown at 4 so that when it is riveted over as shown in Fig. 4 it will split as shown in Fig. 6. The portion 1 may be provided with a slot 5and a hole 6 therein to accommodate electrical conductors leading thereto. of sheet metal 7, Fig. 4, and insulating same therefrom, an insulating washer 8 is placed on each side of the sheet metal 7, and the thimble ortion 3 of the terminal is then inserted t rough the washers 8 8, and the plate 7, and riveted thereto. The hole through the plate 7 is considerably larger than the holes through the washers, so as to give considerable'clearance between the terminal and the plate. In riveting, the thimble portion 3 is tightly riveted over as shown in Figs. 4 and 6, thereby tightly squeezing washers 8 8 against the plate 7 and together through the hole therein. This riveting makes a perfectly tight joint between the plate 7 and the thimble 3, and at the same time insulates the terminal from the plate. The plate 7 may be provided with projections 9 9 thereon to press in washers 8 8 to prevent the washers from turning on the plate after the terminal is riveted thereto. The bottom portions 10 of the thimble 3 embed themselves in a washer 8 so as to prevent the terminal fromturning in the washer.

InFig. 7 the condenser is provided with the terminals of my invention secured to the lid 11 thereof as just described in connection with Figs. 4 and 6. The conductors 17 17 leading from the conducting strips of the condenser, inside the case '12, extend through the 'hollow thimbles 3 3 of the terminals and are soldered thereto by solder 13 which completely seals up the apertures leading from In securing the terminal to a piece and 16 leading to any suitable circuit arrangement, may/be; secured to the portion 1 1 of the terminals in the usual manner.

In Fig. 9 1 have shown a modified form of my terminal provided with two legs 1 1 thereon and riveted to an insulating distributing strip l4. In securing these terminals to the strip 14 it is not necessary to use insulating washers 8 8, as in Fig. 4, as the terminals are riveted direct to the strip 14. Conductors 15 and 16, to be distributed, may be soldered to the portions 1 1 of the terminal, as shown in Fig. 11. If desired, conductors may be brought from the rear of the strip 14 through the hollow portions of the terminals and soldered thereto as described. The distributing strip of Figs. 9, 10 and 11, may be suitably mounted in place in the usual manner.

I do not wish to limit this invention to the particular details of construction as herein shown, as many modifications may be made without departing from the scope of the invention.

What I claim as my invention and desire to secure by Letters Patent is;

The combination with a metallic casing formmg an inclosure for electrical conductors, of a one-piece terminal member having a hollow portion extending through the wall 3 of the casing and a'portion exterior of the casing extending out therefrom and adapted for a terminal for an external conductor, insulating members for insulating the said hollow portion from the metallic casing, the 1 said hollow portion being riveted to the said insulating members whereby the said terminal member is securely mounted to the said casing, means for preventing the said terminal member from turning relatively to the HERBERT G.
