ATTORNEYS WILLIAM HENRY BRIGGS, or RICHMOND HILL, NEW YORK.

ELECTRICAL CONNECTIONr Specification of Letters Patent.

' Patented Dec. 29, 1908.

Application filed May 9, 1908. Serial No. 431,985.

ToaZZ whom it may concern:

Be it known that 1, WILLIAM HENRY BRIGGS, a. citizen of the United States of America, residing at Richmond Hill, in the county of Queens and State of New York,

have invented certain new and useful Improvements in Electrical Connections, of which the following is a specification.

My invention relates to electrical connec tions and particularly to battery connections, the object of my invention being to provide a device of this character which is not only simple in construction but efiicient and durab e in service.

In the accompanying drawings in which my invention is illustrated, Figure 1 is a perspective view of a battery connection of my improved construction; Fig. 2 is a perspective View of a modified form of terminal clip for the connection; Figs. 3 and 4 are perspective views showing my method of tying the clip to the connecting wire; and Fig. 5 is a perspective of a dry battery showing my clip applied to one of the binding posts.

As shown in the drawing this clip, which is secured to the wire 10 by a special tie, hereafter to be more fully described, comprises opposed wings 11 and 12-angled away from each other, but united by a looped spring section13, which is formed to retain the wire.

The wings are provided with registering perforations through which the binding post 14 passes, or they are forked as shown in the up- .per clip, Fig. 1, in which case the binding post is slipped between the legs of the fork. n Fig. 2 t e lower wing is longer than the upper and the legs of the fork act as guides.

It will be noted also that theupper fork is slightly offset at 15, so that when the cliplis slipped on the binding post the offset portion of the upper fork passes beneath the outer edge of the binding screw 16 or head 19, and

thus locks the clip in position.

In using the forked clip, which is the preferred construction, the binding post, if provided with a screw 16, is slightly spread at its upper end and the binding screw turned up until it is stopped thereby. In this position the screw 16 corresponds to the rigid head 19 50. of. the notched post 18 shown-in Fig. 5. The forked clip'is in either case slipped beneath the head of the binding post, against which it is constantly held in frictional contact by the tendency of the wings to spring apart, while the ofiset portion 15 of the upper fork passing beyond the outer edge of the head, prevents the clip from becoming unintentionally disengaged. I

When the perforated clip is used the binding screw must of course be first removed, and afterv the clip has been adjusted over the post, the binding screw is turned down until a satisfactory contact is established. The pressure of the clip against the screw tends to bind the latter on the post so that it does not work loose. The forked clip obviates the necessity of removing the binding screw since a perfectly satisfactory contact is secured by merely slipping the clip on in the manner above described.

Another feature of my invention is the tie by which not only is the clip attached to the wire 1.0 but the electrical contact between the two secured. As shown particularly in Figs. 3 and 4, a hole 17 is punched in the spring loop and the bared end of the wire inserted through the same from above. The wire is then bent down and carried around the end of the loop and then up between the spread wings of the clip until 1t lies within the loop which, as previously stated, is especially formed to receive and hold the wire thus placed when the wings are again in their normal position. If the clip be stamped as a whole from spring sheet metal, as isthe preferable method of manufacture, the wings will probably return to their normal osition without pressure. I If this is not t e case however, slight pressure may be necessary to close the loop about the wire after the tie is completed. When in this position however, the tie is perfectly secure and the electrical fcontact between the clip and the wire perect.

Vhile thedetails above described arexthe preferred construction of my device, they may be varied without departing from ,my invention, and I do not limit myself to the exact structure shown.

I claim as my invention: l

A battery connection, or the like having a terminal clip provided with a spring loop uniting opposed wings adapted to engage a binding post, said loop being perforated as described, in combination with 'a oonnec-ting I In testimony vyhereof I have signed my wire, the bared end of which is inserte name to this, specification, in the presence of through said perforation from above and the two subscribing witnesses.
