1 Claim.

As the title of the invention implies, the device hereinafter specifically described has reference to an improved type of terminal clip such as is adapted for connection with the post of a conventional storage battery.

Needless to say, we are aware of the fact that the art to which the invention pertains is characterized by innumerable types and forms of 'socalled terminals of the clamp and clip form. Notwithstanding this highly developed state of the art, we have evolved and produced a novel contribution which, it is believed, possesses features which transcend those exemplified in marketed and patented terminals.

It follows, therefore, that our primary aim is to generally improve upon prior art devices known to us by providing a simple and economical sectional terminal of a two-part clasp type susceptible of expeditious application and removal, and not likely to become anchored on the post by adhesion caused by corrosion.

The specific adaptation and coordination of features will become more readily apparent from the following description and the accompanying illustrative drawing.

In the drawing:

Figure 1 is a view partly in section and partly in elevation showing a terminal clamp constructed in accordance with the principles of the present invention.

Figure 2 is a side elevational view observing the details illustrated in Figure l in a direction irom left to right.

Figure 3 is an elevational view of the opposite or diametrically opposed side of the clamp, that is, observing it in a direction from right to left in Figure l. a y

In the drawing, in Figure l, the conventional storage battery is denoted by the numeral :3 and the tapered post is indicated at 5. These are conventional parts. The sectional or two-part terminal clamp is indicated by the numeral 6. This may be said to be made of a pair of companion or complemental clip units l and 8, respectively. These are formed from metal of appropriate proportions and are substantially alike in construction. The lower end portions are of arcuate or semi-circular form as indicated at 9 to form jaws which efieetively grasp and embrace the post. The jaws are shaped to conform to the contour of the post. The intermediate portions of the units are profided with overlapped lugs or cars ill pivotally' connected together in hinged relationship as indicated at H. The upper end portion is of the unit or section? is formed with a reinforcedv screw-threaded? hole forming a. nut iii to accommodate the screwthreaded stem it! oi the fastening or binding set screw. The outer end of the set screw is formed with a finger piece I! to facilitate actuation. The inner end is rounded somewhat to provide a thrust element I! which is seatable in a socket formed in the thickened upper end portion ll of the unit 8. It follows therefore that the jaws 9 are simply slipped down over the post and the set screw is tightened YDIOI'OG the jaws into efiective binding contact with the post. This set screw arrangement and thrust action is an important factor distinguishing the invention.

We call attention now-to the adapter clip l8 which is constructed and formed as an integral part of the unit 8 to accommodate the cable or conductor line (notshown). In addition, as an' important feature, we call attention to the numeral l9 which indicates a. stop element, this being integral with the law on the part 1 and located at 'right angles thereto so as to overlie the end of the post. This limits the downward placement or positioning of the clamp 6 as a whole. In addition to this, it serves, when the parts I2 and I! are pressed together with a tool, to bear down against the post and to break the corrosion bond, if any, and to aid in loosening the clamp it it has a tendency to adhere to the post. Thatis to say, as the parts I and 8 are pressed together at their upper ends with a tool, this tends to cant the stop element l9 against the post producing a thrust action which is helpful in releasing the clamp from the post.

It is thought that persons skilled in the art to which the invention relates will be able to obtain a clear understanding of the invention after considerlng the description in connection with the drawing. Therefore. a more lengthy description is regarded as unnecessary.

Minor changes in shape, size, and rearrangeping ears on intermediate portions of the jaws pivoted together to form a hinge, a screw thread= ably mounted in one jaw and adapted to bean on the other Jaw to detachably lock the jaws in closed position on the post oi a battery, a laterally projecting conductor sleeve on one jaw, a

horizontal bridge wall formed on the other jaw below the hinge and extending across the major portion or the space between the jaws whereby a fulcrum is provided for canting the jaws free from a corroded pest and at the same time prevent corrosion from efiecting the hinge.
