STORAGE BATTERY TERMINAL CONNECTER Filed Nov. l. 1929 Y INVENTOR WITNESS ATTORN EY Patented June 2,` 1931 UNITED Ysra ALLAN WILLIAMS FI'SHER, OF ST. PETEBSBiURG, FLORIDA STORAGE BATTERY TERMINAL CONNECTER Application led November 10 and contact with the terminal.

With these objections in mind itis the primary object of my invention to provide a battery terminal connector which is encased in a yieldable housing which will tightl hug the battery binding post and effect a lquid seal so that it willbe impossible for any of the electro-lyte or other foreign substance to find its way to the terminal and the metal,-4

'llc connector associated therewith.

With the preceding and other objects and advantages in mind, the invention consists in the novel combination-of elements, con- Structions and arrangements ofparts and operations to be hereinafter more fully described, claimed and illustrated in the accompanying drawings,wherein:j

Figure 1 is a perspective of my invention operatively connected with a lstorage batwry,

Fig. 2 -is a longitudinal sectional on line 2 2 of Fig. 1;

'Fig 3 is a vertical transversesection taken on line 3-3 of Fig. 2; and Fi 4: is a view in perspective-of the combine ring and clamping jaws..

Referring to the invention in detail a split resilient kloop 'or ring 5 whose terminals are formed with laterally extending parallel transversely bowed clamps 6 is provided.

'The loop 5 is adapted to be receivedon the usual tapered battery binding post 10 and the inner face of the loop is bevelled or graduated in thickness from its lower edge to its upper edge to conform to the contour ofthe 3o view taken binding post. The sln'nned terminal 11 of electrical conductor 10 is arranged between the clamping jaws with one end abutting the binding post as disclosed in Fig. 2. In order to clamp the terminal 11 the opposed faces of the clamping member 6 are provided with 1, 192s. seriall No. 404,154.

teeth or ribs 13 which are forced into the terminal when the jaws are forced together as will be hereinafter pointed out. The inner ends of the clamping-members are flared as at 14 to permit the terminal to spread so that 55 a maximum cross sectional area of the same will contact with the'binding post. l,

Inl order to hold the clamping jaws in clamped engagement'. with the terminal an internally threaded sleeve 15 is provided and 60 is engaged with exterior threads 17 on the jaws 6. When the sleeve is screwed home the interior screw threads bite into the terminal and thereby positively bind the latter to the sleeve.

The outer endof the sleeve is provided with a wrench engaging surface 19 so that the sleeve maybe threaded on and off the jaws 6. v

In order to prevent electro-lyte, water, etc., from contacting with the conductor 12 and the connector a housing is provided which is formed of elastic material and comprises a rounded portion 2l in which the split ring 5Yis encased and a laterally extending sleeve- 75 like portion 22 which receives the interiorally threaded sleeve 15. The interior of the sleeve-like portion 22 is flared as indicated at 23 and the exterior of the sleeve 15 is tapered. Thus the sleeve 15 may be easily in- 80 serted and removed from the sleeve-like portion 22. The rounded portion is provided with an opening 24 in. its lower wall which is concentric to the split ring 5.

With the device connected withthe bind- 35 ing post it will be seen that the walls' of the opening 24 tightly hook the binding postV and due `to the elasticity of the housing a liquid seal-is effected. It will beftherefore apparent that electro-lyte, Water, etc., cannot find its wayinto the housing and cause the metallic parts to corrodef, I

What is claimed is:` 2

A storage battery connector comprisi'n 1 a split resilient ring provided with parallel 5 transversely bowed clamping arms extending from the ends of said ring and adapted to Yreceive a conductor terminal,therebetvireem4 the clamping arms being externally`thread ed, an internally threaded sleeve screwed 1 on the clamping arms' and serving to hold the split ring in clamped engagement with a battery binding post and to holdthe arms in clamped engagement with the battery ter- 5 minal, the outer Wall of the sleeve tapering inwardly from the outer end and a housing formed of yield'able rubber surrounding and snu ly tting the split ring and the internally t readed sleeve, said housing having an lo opening located in registration with the split Y ring, the Walls of the opening being adapted to yieldably grip a battery binding post to eieet a liquid seal around the same, the portion of the housing surrounding the sleeve having the inner Walls thereof tapered in an opposite direction to the tapering of the sleeve so that when the sleeve is screwed into place the outer Walls of the sleeve Will form a tight fit with the inner contacting Walls of that portion of the housing which embraces the sleeve.
