Application filed August 9. 1924. Serial No. 731,009.

The present invention relates to wire ter- In addition to the general ob ects of this invention, which are toprovide a particularly simple, practical, inexpens ye and efli cient wiring terminal, s ecial ob ects of the invention are to provi e a terminal WhlCll can be quickly applied to the wet cell type of B batteries now used in radio worlr' and which while readily detachable will make positive and secure electrical connection in any one of many powible ad ustable enga ements.

Ot er objects and the novel features of construction, combination and relations of parts by which such objects are attained willbe set forth in the following specification. A Q In thedrawing accompanying and comiprising part of this specification the lnvention is illustrated embodied in only one form,

but it should be understood that the stnic ture may be changed and modified in various wa s without departure from the spirit an scope of the invention, as hereinafter described-and broadly claimed.

In said 'drawing: 3 Fig. 1 is a plan view of a multiplecell battery with two applications ofthe terminal clip shown. Fig. 2 is an enlarged broken view ofthe cell shown in the upper right hand corner of Fig.1 with the clip on the free terminal of the same. r

Fig. 3 is a side elevation of the structure of Fig. 2 as viewed from the right. Fig. 4 is a horizontal section on the line 4-4 of Fig. 2.

i Fig. 5 is an enlarged transverse section on the line 5-5 of Fig. 1.

Fig. 6 is a further enlarged vertical cen line until the single shown in the form of a fiat base part 13,

secured in back-to back relation to the flat base 1401? the wire gripping portion,having dependent from one side of the same a relatlvely narrow spring strip 15', doubled back upon itself to form an introverted spring/'60 contact finger 15 and from the opposite side a pan of spring strips 17, doubled back toward the 'base in the-form of introverted tongues or fingers 18.. This entire portion 6 is usually made of a single piece of spring sheet metal with the parts out so that the single finger 16 stands opposite the space between the pair. of fingers 18, providing the triangular relation shown in Figure 4,,

whereby a battery pole 19, or the like, engaged by the device will be gripped between the two out edges of fingers 18 and the fiat face of'finger 16. Also preferably the space between fingers, 18 is at least'as great as the'width of finger 16 so that to increase the .gripping force the opposed gripping fingers may be squeezed to ether, past the "center nger passes in between the other-two. The wire, gripping section of the device I also is usuallyformed of a single piece of spring strip stock and the two parts are conveniently secured in their back-to-back relation by a single tubularrivet extension 20 on one, engaged through an opening provided in theother. v

Some of the uses of the clip are illustrated is shown made up of cell units 21, joined by connector bars 22, theend cells having the cylindrical terminal'posts or pins 19.

'In this view one of the clips is shown forced down over the terminalpost of the end cell in the upper right hand cornerand a second clip is shown forced down over the connec- "in Figure 1, w'herea wet cell. B battery. Q a

clean solid contact andFigure 5 shows how in the second case a three point engagement is effected with the opposite sides .of the con nector strips, establishing a flat firm full-. areal contact. In'both instances, it is simply necessary to push the clip down over the part which is to be wired. Disconnection is effected just as easily by simply pulling the clip straight ofl, but 'the grip of the three fingers is suficient to prevent any accidental disengagement.

The introversion of the spring fingers provides length and resiliency enabling the fingers to adapt and fit themselves to the shape of the battery post'or other conductor.

Thus these fingers stand parallel in gripping 'a parallel-sided object or turn at various angles to take firm hold of angular,

- curved or'irregular shaped bodies.

If desired, the clip may be sheathed with a n0n-c0rr0sive cover 21, of lead or the like,

such as indicated in Figure t. This sheath, in the case of a two-part clip, such as illustrated, has the furtherefiect of unifyixigithe parts both inan electrical and a mechanical sense and overcomes the possibility of one part twisting with respect to the other about the center provided by the'rivet connections between the two.

The triangularly related and relatively A long spring attaching fingers on the base of the clip. support the wire gripping head of the clip in elevated position where it can be readily manipulated for attachment and detachment of the wire. The push and pull attachability and detachability of the clip make it particularly desirable for testing purposes when quick changes of connections -wardly from; one end flange, and a single finger extending downwardly from the aromas K- are required and the structure assures that good contact will be made without requiring the user to exercise any special care.-

.What is claimed, is: A wire terminal having a lower post engaging portion comprising a flat rectangular plate provided with downwardly extending flanged ends \of the same Width as the late, j

a pair of" spaced fingers extending ownjacent thelfirst mentioned flanges, said last.

flanges having their middle portions of V- shape with the'points of the Vs directed toward each other, the V-shaped portion of one flange having a rectangular opening therein and the V-shaped portion of the I other flange being of a width to pass through said opening mc'um PLEASANT rAunrsrocx.

In testimony whereof I aflix my signature.
