Sept. 24, 1935. c. E. HOOVER SOLDERLESS BATTERY CABLE GRIP Filed June 8, 1933 Patented Sept. 24, 1935 UNITED STATES PATENT OFFlC SOLDERLESS BATTERY CABLE GRIP Charles E. Hoover, Lancaster, Pa. Application June 8, 1933, Serial No. 674,956

3 Claims.

My invention relates to means for connecting battery cables to terminals for use with storage batteries and it has for an object to provide a means whereby the cable even though most of its strands shall have been broken "on may yet be securely held, in an acid-proof way, to the terminal.

Further, it is an object to provide a means to receive a cable end, which means is so constructed that it will have an acid-proof pocket in which the wire strands are held, the entrance to the pocket being closed by the insulation of the cable.

Further, it is an object to provide a solderless battery cable grip terminal which is protected against corrosion either by creeping acid or by acid fumes entering the cable socket thereof.

Further, it is an object to provide a solderless cable grip having a straight sided standard threaded plug to fit a threaded hole in the body which has the recess for the cable ends, the plug having a nut head of smaller diameter to allow the plug to be screwed in and accommodate any desired grip according to the number of strands or size of the cable.

A further object is to provide a solderless battery cable grip terminal which will interlock with the cable regardless of whether or not it be of few or many strands.

Further, it is an object to provide a battery cable grip using a screw plug to which other :able terminals may be anchored.

Other objects will in part be obvious and in part be pointed out hereinafter.

To the attainment of the aforesaid objects and ends, the invention still further resides in the iovel details of construction, combination and irrangement of parts, all which will be first fully described in the following detailed descripion, then be particularly pointed out in the apxended claims, reference being had to the ac- :ompanying drawing, in which:

Figure l is a horizontal section on the line I of Figure 2.

Figure 2 is a vertical section on the line 2-2 f Figure l.

Figure3 is a vertical section of a modified orm of the plug.

Figure 4 is an elevation of a modified tom of he plug.

Figure 5 is an elevation of another modified orm of the plug.

Figure 6 is an elevation of a battery terminal with screw shank to lit the threaded bore oi the lug H.

In the drawing, in which like numerals of reference indicate like parts in all the figures, I represents the body of the cable terminal, which body has a flared entrance portion or hell mouth 2, and a threaded plug receiving hole 3, the latter being of greater diameter than the width of 5 the wire receiving socket which is composed of parts 5, 6, l and II, and which intersects the hole 3 at right angles. The bottom of the threaded hole is concave as at 4 and lies at a lower level than the bottom I of the wire socket (see 10 Figure 2) to constitute a seat. 8 represents the portion of the terminal by which it is adapted to be connected to a battery post. The concavity 4 is provided with a central teat or protuberance I! to enter a recess 2| in the screw plug II. The plug ll has a nut head l2, preferably of lesser diameterthan that of the plug as a whole, to receive a wrench for turning the same.

It may also be bored and tapped at I8 to receive the screw I9 whose cap is adapted to re- 20 ceive a wrench for the purpose of turning the same.

The battery cable is designated by the numeral l5 and its strands by the numeral it (see Figure 2).

If it be desired to hitch a split type clamp connector to my terminal, a terminal 22, 22b, 220 of the battery post type (see Figures 4, 5 and 6) may be formed on the plug or screw. Also, instead of making the plug with a threaded bore, it may be made as shown in Figure 3. namely, with a blind end bore 23, the entrance to which is fiared as at 2|.

In Figure 3 those parts which correspond to like parts in Figure 2 bear the same reference numeral plus the index letter d; in Figure 6 those parts which correspond to similar parts in Figure 2 bear the same reference numeral plus the index letter a; in Figure 4 those parts which correspond to similar parts in Figures 2 and 6 bear the same reference numeral plus the index letter b; in Figure 5 those parts which correspond to similar parts in Figures 2, 4 and 6 bear the same reference numeral plus the index letter 0; so a further detailed description thereof is thought to be unnecessary. I

From the foregoing description, taken in connection with the accompanying drawing, it is thought that the complete construction, operation and advantages of my invention will be clear to those skilled in the art', and I wish it under: stood that further changes in the details of construction and arrangement of parts than those illustrated may be made without departing from 55 the spirit of the invention or the scope of the a pended claimsi What I claim is:

1. A battery cable terminal comprising a body having a longitudinal wire receiving chamber which is provided with straight side walls, a top and a V-shaped bottom wall, said body having a flared entrance to said chamber, said body having a threaded bore of greater diameter than the width of said longitudinal chamber, the axes of said bore and chamber intersecting one another, said body having a concaved seat at the inner end of said threaded bore below the level of said longitudinal chamber, a screw plug fitting said threaded bore and having an end to cooperate with said seat, said seat having a protuberance and said plug having a recess to cooperate with said protuberance.

2. A battery cable terminal comprising a body having a longitudinal wire receiving chamber which is provided with straight side walls. a top and a V-shaped bottom wall, said body having a flared entrance to said chamber, said body having a threaded bore of greater diameter than the width 01' said longitudinal chamber, the axes of said bore and chamber intersecting one another, said body having a concaved seat at the inner end or said threaded bore below the level of said longitudinal chamber, a screw plug fitting said threaded bore'and having an end to cooperate with said seat, said seat having a protuberance and said plug having a recess to cooperate with said protuberance, said body having a pocket at the inner end oi. said longitudinal chamber for the purposes described.

3. A battery cable terminal comprising a body having a longitudinal wire receiving chamber and a threaded bore intersectingthe chamber, combined with a threaded plug in said bore, said plug and said body having a concaved clamping surface located below said chamber and said plug having a convexed surface at its inner end to cooperate with said concave surface, said body having a protuberance from said concaved surface and said plug having a recess to register with said protuberance.
