.P. E. CASE.


1,019,423. Patented Mar.5,1912.



I can rants rib-1i;



1?) all whom it may concern:

' Be it known that I, FRANK E. Case, a citizen of the United States, residing at Schenectady, in the county of Schenectady and State of New York, have invented certain new and useful Improvements in Terminals for Electric Conductors, of which the following is a specification.

This invention relates to connecting terminals for electrical conductors and has for its object the provision of a device of this character which is very inexpensive to man ufacture, while at the same time being very reliable and convenient.

One of the objects of my invention is to producea terminal from a metallic strip which maybe punched out of or cut from sheet metal and which may be given the desired form under a punch press with the use of very little or no hand work.

In carrying out my invention I punch a blank out of sheet metal which is provided at its opposite ends with wings which are adapted to be bent so as to form holdlng clips for the conductor. The strip is then bent intermediate its ends so as to bring the two clips adjacent. Y K

In the drawings, in which I have shown a preferred embodiment of my invention, F igure 1 is a plan view of a punched blank from which my connecting terminal is formed; Fig. '2 is a perspective View of the terminal completely formed; and Fig. 3 is a view of a pair of terminals supporting insulated conductor, while the clip 12 encircles the conductor itself, thus making a very firm support for the conductor and at the same time a thoroughly efficient electrical connection. The strip is also preferably perforated at 13 and 14. The strip is then bent Specification of Letters Patent.

Application filed March 7, 1906.

Serial No. 304,648.

7 upon itself intermediate the perforations,

as on the line 15, so as to bring the wings longitudinally adjacent each other, the wings preferably being first formed into the clips. If the perforations are made in the stri before it is bent on itself the line of hen ing should be such that the perforations will come fair with each other. here the clips 11 and 12' are to be of different sizes it is of course desirable that they be coaxial, or concentric, where, as in the pres ent case, they are circular. This is done, as shown in Figs. 2 and 3, by bending the metal adjacent the clip 12, as at 16, 'so as to give the clip an 'ofiset to make them concentric. The clips may be formed in the punch press or in any desired manner, and the bending of the strip on to itself may be similarly form a securing and fastening means for the terminal, although, of course, other means may be provided without departing from the spirit of my invention. These clips may be used in pairs and secured by means of the ,bolt 17 and nuts 18, as shown in Fig. 8.

Tatented Mar. 5, 1912.

It will thus be seen that I have provided a very simple and efficient terminal which, in addition to forming a firm and reliable support-for the conductors, makes also a very eflicient contact. The insulation is firmly held in place and the ravcling of the insulation is prevented.

It should be understood, of course, that various modifications ofgny device will suggest themselves to those skilled in the art, all of which will ooine within the spirit of my invention in so far as they fall Within the scope of the claims annexed to and for1ning a part of this specification.

What I claim as new and desire to secure by Letters Patent of the United States, is,

1. A terininal for electric conductors comprising a metallic strip having holding clips formed at opposite ends thereof,'said clips being arranged so as to be eo-axial and .engage adjacent portions of the conductor.
