3Claims.

The main object of this invention is the provision of a novel electrical cable terminal or connecter particularly adaptable to storage batteries as used on automobiles, where there is considerable and sometimes severe vibration and shock which tends to loosen the ordinary connecter, and this invention aims to prevent such loosening as a result of such disturbances.

Another object of the invention is the provision of a cable terminal connecter which permits quick and simple detachment of the connecter without the aid of tools and in a minimum of time.

Still another object of the invention is the provision of such a connecter which may be readiLv snapped on or 011 a terminal post with the fingers.

Yet another object of the invention is the provision of such a terminal with means for readily and simply tightening the connection in case it should for any reason become loose, as.

for instance as a result of corrosion.

And yet another object of the invention is the provision of such a connecter with means for adjusting the vertical position of the terminal on a battery post so that lost play resulting from wear or corrosion may be taken up and the connection again made securely tight.

Figure 1 is a plan view of the connecter applied to a storage battery terminal.

Figure 2 is a side elevational view of the same.

Figure 3 is a perspective view of one of the clampin jaws.

Figure 4 is a perspective view of the connecter per se, prior to its application to the terminal post.

The above and other objects of the invention will become apparent in the descriptionbelow, in which characters of reference refer to -10 like-named parts in the drawing.

Referring briefly to the drawing, the reference numeral 10 indicates an upwardly-tapering terminal post of lead, such as is commonly used on storage batteries, having a widened base 11 usually lying flush with or upon the surface of the battery. The connecter of this invention comprises, first, an outwardly-tapering body 12 having the usual opening therein, shown dotted in Fig. 2 for the insertion of the end of the cable,

the latter being soldered therein. At the end of the body 12 oposite the hollow end, a rounded mount 13 is formed by opposing curvedjaws 14 extending from the body 12, these jaws engaging the post 10 on one side as shown in Fig. 2. Projecting bosses 15 extend, one from each side,

from the rear of the jaws 14, and have the ends of a substantially U-shaped resilient member 16 looped thereabout, thus pivoting the ends of this member on' these bosses.

A locking member 18 has its lower end bent around as shown in Fig. 2, to provide a sleeve 19 having an axial opening therein through which passes the bridging arm 17 of the resilient member 16. A separate clamp member 25 is mounted against the post 10 opposite the mouth 13, and is provided with rounded jaws 20 enclosing a mouth 21. The jaws of both members are of such width that when both are mounted as shown in Figs. I and 2, a vertical space is provided between adjacent edges of opposite jaws. The outer face of the clamp member 25 is flat, as shown at 22, and one or more horizontal grooves 23 are provided centrally in said flat face. One side of the sleeve 19 is extended to form a substantially sharp edge or ridge 24 which is adapted to register in the groove 23. All of the parts described, excepting the resilient member 16, are made of lead, or other suitable metal.

In using the device, the mouth 13 is first placed against the post 10, with the locking member 18, with its extended, flattened handle or grip 26, swung into substantially vertical position. The clamp member 25 is then placed against the post opposite the mouth 13, and the member 18 is swung downward with the ridge 24 lying at the entrance to the groove 23. The handle 26 is then swung downward and toward the post 10, whence the ridge 24 is wedged firmly into groove 23, looking the opposite mouths against the post as shown in Fig. 2. The resiliency of the member 16 provides a tight connection at all times and causes absorption of vibration and shock such as loosens ordinary battery connecters. In case the post should become worn or corroded and its diameter thereby lessened, the jaws are simply lowered a distance to a point where the tapering post is sufficiently wide to insure a tight closure.

It is obvious from the above that the procedure of attaching the cable to the post, or detaching the same, is a very simple operation, being accomplished simply by means of the fingers without requiring the use of tools such as pliers or screw drivers, as is usually necessary.

It is to be noted that modifications in form 105 and structure may be made without departing from the spirit and scope of the invention.

We claim:

1. In a device adapted to releasably connect a cable to an upwardly tapering terminal post, a 110 pair of jaws, one of said jaws having the cable secured thereto, said jaws engaging said post, pins extending from opposite sides of one of said jaws, a substantially U-shaped resilient member having coiled ends rotatably mounted on said pins, a locking member comprising a sleeve portion rotatably mounted on said resilient member opposite to said pins, a handle portion extending from one side of said sleeve portion, a wedgeshaped ridge extending from the opposite side of said sleeve portion, said device being locked to said post by rotating said resilient member to enclose both of said jaws and causing said sleeve to lie adjacent the back of the other of said jaws, said handle being rotated downward toward said post to cause said ridge to frictionally force said other jaw downward on said tapering post to tightly lock said jaws on said post.

2. In a device adapted to releasably connect a cable to an upwardly tapering terminal post, a pair of jaws, one of said jaws having the cable secured thereto, said jaws engaging said post, the back of one of said jaws having a plurality of spaced-apart parallel grooves therein, pins extending from opposite sides of the other of said jaws, a substantially U-shaped resilient member having coiled ends rotatably mounted on said pins, locking member comprising a sleeve porjaw, said handle being rotated downward toward said post to cause said ridge to register in one of said grooves to frictionally force said grooved jaw downward on said tapering post to tightly lock said jaws on said post.

3. A device of the class described comprising a pair of jaws, one of said jaws having means for connecting a cable thereto, said jaws being adapted to engage an upwardly tapering terminal post, a substantially U-shaped resilient member pivotally mounted on one of said jaws, a locking member having a sleeve, the base of said U-shaped member being mounted rotatably in said sleeve, the other of said jaws having a groove therein, a ridge on said locking member engageable with said groove to cause said member to force said other jaw down toward the base of said post to lock said jaws releasably against said post.
