CONDUCTOR CONNECTER Filed March 19, 1929 Patented Feb. 16, 1932 UNETED STATES JOSEPH B. JURAD, OF NEWTON, MASSACHUSETTS CONDUCTOR CONNECTER Application filed March 19, 1929. Serial No. 348,176.

The invention relates to clips for connecting conductors to terminals, as, for exanr ple, for connecting a jumper wire to the terminal of a storage battery.

The invention will be best understood from the following description when read in the light of the accompanying drawings showing one example of the invention, while the scope of the invention will be more particularly pointed out in the appended claims.

In the drawings Figs. 1 to 3 show a clip constructed according to the invention in difierent operative positions relative to the terminal of the storage battery; and

Figs. 1 and 5 respectively are plan and bottom views of the terminal according to Fig. 1.

In the embodiment of the invention illustrated by the drawings, the clip is formed of a spring plate, preferably by stamping it from a sheet of spring steel and bending it to shape by means of suitable dies, after which it is coated with lead in the usual manner for preventing corrosion.

As shown, the clip comprises a U-shaped portion 1 having the legs 3 and 5, the leg 5 being connected by a curved portion 7 to an arm 9, while the leg 3 is connected by a curved portion 11 to a terminal contacting portion 13, the latter directed toward the curved portion 7 As shown, the portion 7 forms a shoulder for contacting with one side of the terminal, while the end of the portion 7 forms an edge for contacting with the opposite side of the terminal. Preferably, but not necessarily, the end of the portion 13 is of arcuate shape and provided with teeth 15, as indicated in Fig. 5, while the end of the arm 9 is reduced in width at 17 and formed at its end to present a tubular part 19 (or formed so that it may be readily bent to a tubular shape) for connecting it to a conductor 21.

In practice, assuming the clip is to be at tached to the terminal 23 of the storage battery, the clip will be first presented to the terminal as shown by Fig. 1. Then, by forcing the arm 9 downwardly, the parts will successively move into the positions shown by Figs. 2 and 3. Preferably, the top of the U-shaped member and right leg thereof, as viewed in Fig. l, are formed on such curves, relative to the curves presented by the left leg, curved portion 11, and portion 13, that all the fiexure substantially occurs in the former, with the result that when the parts are in the position shown by Fig. 2, the distance between the center of curvature 25 of the curved portion 11, and the point of contact 27 at the opposite side of the clip with the terminal, is greater than when the parts are in the position shown by F ig. 3, with the result that the terminal snaps from the position shown by Fig. 2 to the position shown by Fig. 3, and is rigidly secured against removal when in the latter position, unless removed by forcing the arm 9 upwardly.

It will be observed that, as above described, no sliding action occurs between the port-ion 13 and the terminal, and that as the parts move successively through the positions shown by Figs. 1, 2 and 3, in attaching the clip, the portion 13 rocks about its point of contact with the terminal, with the result that the teeth 15 bite into the material of the terminal, commonly lead, and secure good electrical contact.

It will be understood that wide deviations may be made from the embodiment of the invention herein described without depart-- ing from the spirit of the invention.

Claims:

1. A clip for connecting a conductor to a storage battery terminal or the like comprising an elongated spring member having a terminal contacting edge at one end portion thereof and a terminal contacting shoulder at an intermediate portion of its length opposed to said edge, said end portion and shoulder being connected by a resilient portion holding them normally in spaced relation, said resilient portion acting to permit said edge and shoulder to grip opposite sides of said terminal in planes transverse to said terminal, and an operating arm at the same side of said clip as said shoulder.

2. A clip for connecting a conductor to a storage battery terminal or the like comshoulder.

prising a spring plate member having a generally U-shaped resilient portion, the latter having at the end portion of one leg thereof a terminal contacting portion directed to- Ward the other leg thereof, an operating arm carried at the end portion of said other leg, and a terminal contacting shoulder portion between said arm and the end of said leg in Which carries said arm.

3. A clip for connecting a conductor to a storage battery terminal or the like compris= ing a spring plate member having a termi= nal contacting edge and a terminal contact= ing shoulder, said edge .and shoulder being connected by a resilient portion holding them normally in spaced opposed relation, said shoulder having a relatively smooth surface or material length whereby said shoulder is readily slidable along one side of said terminal While said edge is in pivotal contact with the opposite side of said terminal.

4. A clip, for connecting a conductor to a storage battery terminal or the like comprisinga spring plate member having a terminal contacting edge and a terminal contactingz shoulder connected by a generally U? shaped resilient portionholding them normally in spaced relation, said edge being carried closer tothe apex otsaid U than said shoulder, the latter having a relatively smooth surface of material length whereby said shoulder isreadily slidab-le alongone side of said terminal, While saidedge isin pivotal contact With the opposite side of said termi-n ah- 5. A clip for connecting a conductor to a storagebattery terminal or thelike comprisinggan elongated spring member having a terminal contacting edge at one end portion" thereof, and a terminal contacting shoulder at an intermediate portion of its length op- P08659130: saidedge, said end portion and shoulder being connected by a generally U shaped resilient portion normally holding, them in spaced relation, said edge normally being. nearer the apex of said U than said In testimony whereof, l2 have signed my name to this specification.
