CONNECTING CONSTRUCTION FOR BATTERIES AND THE LIKE. I

Application filed January 14, 1922. Serial No. 529,120.

To all 'wkom it may concern:

Be it known that I, THEODORE S. Conn, a citizen of the United States, and a resident of New Haven, in the county of New Haven 5 and State of Connecticut, have invented an Improvement in 7 Connecting Construction for Batteries and the like, of which the following is a specification.

This invention relates to electrical con- 10 necting devices and alloys for making same,

and with regard to its more specific feature,

to connecting devices for storage battery terminals.

' One object thereof is to provide a practical device of the above character adapted to meet the conditions of hard use.

Another object is to provide a device of 'the above nature of strong and simple con; struction, which shall be secure and dependabl'e in action.

Another object is to provide a device of the above naturewhich can be readily assembled and taken apart.

Another object is to provide a practical and inexpensive alloy for forming a device of the above nature.

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

The invention accordingly consists in the features of construction, combinations of elements,'arrangement of parts, and combinations of constituents, all as will be illustratively hereinafter described in the .scope of the application which will be indicated in the following claims. 7

The accompanyiii drawing is a side elevation of one of t e various possibleembodiments of theinvention.

Referring to this drawing in detail there is shown at 1, one of the members which is to be connected and it may .be considered a terminal lead member of a storage battery. At 2 is shown the other member which is to be connected and which may take the form ofthe le-ad'covered metallic eye or ring at the end of a storage battery lead.

Obviously the invention is applicable to other members, but it is of special advantage in making connection between members the surface of which is lead.

It being understood that the members 1 and 2 are perforated as indicated by the dotted lines 3, there is passed therethrough a bolt having a head 4 and shank 5, the

- latter being threaded and provided with a nut 6. This nut'is preferably provided with a boss or shoulder 7.

The bolt and nut above referred to em body certain of the broader features of this invention'and as conducive to a thorough understanding, the following brief explanation is made at this point.

The connected parts being of the nature herein dealt with, there is a likelihood of injury or deterioration of the parts due to not only the corrosive action of acid which comes in contact therewith, but to electrolytic action between the parts. For example, if the parts to be connected are provided with a lead surface and the connecting device be formed of brass, the difference of potential will give rise to electrolytic action, if an electrolyte be spilled on their surface and will quickly injure the parts. On the other hand, the use oflead as the material for-a connecting member is objectionable due to its physical qualities and even a lead coated member is for similar reasons unsatisfactory.

The present invention accordingly comprises the formation of the bolt and nut above referred to of an alloy having a similar potential as against sulphuric acid as that possessed by lead, and having nevertheless such physical'qualities as will well adapt it for use in this relation. For this bismuth is found to attain the above advantages, possessing excellent degree of plhlysical strength and being readily worka e.

Accordingly the bolt and nut are formed of an alloy, the composition of which is illustrated above, and by the use of this alloy in the relation set forth, the various objects of this invention are achieved.

It may be here noted that wherever the term leaden is used, it is to be 'ven a broad meaning, to indicate any mem er, the surface of which is lead or contains a substantial proportion of lead.

As various changes might be made in the aboveponstruction and in the constitution of theabove alloy without departing from the see sto d that the matter herein described and of this invention, it is to be underthat shown in the accompanying-drawings are to be interpreted as illustrative and not in a limiting sense.

Having described my invention What I claim is: I

1. In an apparatus of the general nature of that herein described, in combination, a terminal connecting device for connecting v adjacent leaden members of di'lferent material from such'members and of substantially the same potential relative to acid as lead, said device being formed of an alloy of tin and bismuth.

2. In an apparatus of the general nature of that herein described, in combination, a terminal connection for connecting leaden members formed of an alloy of tin and bismuth, comprising several parts of tin to one part of bismuth.

I 3. In an apparatus ofthe generalnaturc of that herein described, in combination, a connection for leaden storage battery members, comprising a bolt passing therethrough and formed of an alloy of bismuth and tin, with the tin constituent substantially greater than the bismuth constituent.

4. In an apparatus of the general nature of that herein described, in combination, a connecting device for storage batteries and the like, comprising a pair of co-acting threaded members each made up of an alloy comprisingtin and bismuth with the tin constituent substantially exceeding the bismuth constituent.

5. In an apparatus of the general nature of that herein described, in combination, a connecting device for storage batteries and the like, comprising a pair of co-acting threaded members each made up of an alloy comprising substantially tin five parts to bismuth one part.-

In testimony whereof, I have signed my name to this specification this 5th day of January 1922.

THEODORE S. COLE.
