Specification of Letters Patent.

Patented Sept. 23,1913.

Application filed January 25, 1911}. Serial No. 604.503.

T 0 all whom it may concern:

Be it known that I, BRUCE FORD, a citizen of the United States, and a resident oi. Philadelphia, in the -count-y of Philadelphia and State of Pennsylvania, have invented a certain new and useful Strap or Connection for Secondary or Storage Batteries, of which the following is a specification.

The principal object of the present invention is to provide a strap or connection which shall be mechanically strong and of good electrical conductivity which shall be capable of resisting any corrosive action to which it is, in use, exposed, which shall be sufficiently elastic or pliable for resisting the .shocks and jars towhich it is subjected, and

u hich shall be capable of convenient attachment and detachment when required.

The invention will be claimed at the end hereof, and although modifications may be made in details 0 arrangement and construction, it will'be described in connection with the embodiment of it chosen for illus- .tration in the accompanying drawings, in which- Figure 1, is a side View, partly in section, illustrating a strap or connection embodying features of the invention in application to a secondary or storage battery. Fig. 2, is a top view, drawn to an enlarged scale, and partly in section of the strap or connec tion shown in Fig. 1, together w th portions of a terminal. Fig. 3, is a side view, partly in section, of the device shown in Fig. 2. Fig. 4, is a side view of a tool in connection with which the strap is useful, Fig. 5 is a sectional view, taken on the line 5-5 of Fig. t. Fig. 6 is across-sectional view of a single strip, and Fig. 7, is a similar view of superposed strips.

In the drawings 1, is a strip as of copper, coated as with lead or lead alloy and corrugated or off-set as at 2, intermediate of its ends. One strip is shown, but, if desired, more than one strip may be employed and in that case the strips can be superposed. The ends of the strip are provided with holes or openings 3 which are somewhat larger'than the lugs 4 of the terminals. At the ends of the strip there are heads 5 as of lead alloy and these heads have through them holes or openings of less diameter than the holes or openings in the ends of the strip 2, so that the material of the heads ineloses the rim of the openings in the ends of the strip. The heads in comparison with the strip are relatively thick 'and Inassive and they'arc provided arpund their openings with projecting flanges 6, the purpose of which will be presently described.

In use the openings in the heads receive the terminal lugs and a e burned or puddled thereto so that good conductivity is insured. of material, as copper, subject to corrosion or attack in use, is coated with lead or the like. The copper adds strength and clas ticity along with good conductivity. The

-set' or corrugation 2 makes the strap springy or elastic and thus protects it from breakage in use. It is often necessary to remove the strap from the terminal connections, and in this connection the flange 6 on the heads is useful. To explain this,referonce is made to Figs. 4 and 5, in which the claw-like jaw 7 has scre\\"-andthread connection with the punch 8 that is surrounded by a skirt 9. In use the claw T underlies the head 5, the punch 8 hears upon the top of the terminal post t and the skirt 9 encir' cles the flange (5. When one of the parts of the tool is moved and the other is'held still, as by means of the handles 10 and 11, the skirt 9 passing over the flange 6 is guided thereby, so that the punch 8 is kept in line with the post 4 and the strap is stripped from the lug.

What I claim is:

1. A connecting strap for secondary or storage batteries, comprising a flexible strip perforated at its ends and permanently provided thereat with perforated'heads, said perforations being co-incident, substantially as described.

2. A. connecting strap for secondary or storage batteries comprising a lcaden coated copper strip perforated at its ends, and perforated massive lcaden heads applied to and inc-losing the ends of thastrip and the rim of openings therein.

3. A connecting stra for secondary or storage batteries comprising a flexible strip having a protective coating and perforated at its ends and permanently provided there at with massive perforated heads, said perforations being co-incident, substantially as described.
