J. PARMESOYN BATTERY TERMINAL CONNECTER Filed Nov. 20, 1955 CII atentecl May 25|, 1937 UNITED STATES `PATENT OFFIQE 7 Claims.

This invention relates to a battery terminal connecter and more particularly pertains Vto the connection between an electrical conductor and a binding post on electrical batteries of the type employed in the electrical systems of motor vehicles.

An object of the invention is to provide a connecter of the yabove character embodying aY clamp adapted to be -aiiixed to the end of an electrical conductor and to be detachably clamped into frictional engagement with Ythe binding post or terminal of a battery in which means are provided for protecting the clamp and the post against becoming corroded under the action of acid fumes emanating from the battery around Ithe base of the post.

Another object is to form the connecter clamp so 'as to obtain the maximum of resiliency therein, whereby connection of the clamp to the binding post and its removal therefrom will be facilitated.

Another object is to provide a construction in the connecter whereby the electrical conductor affixed thereto will be held in -an elevated position relative to the top wall of a battery box and whereby application and removal of the clamp is facilitated.

With the foregoing objects in View together with such other objects and advantages as may subsequently appear the invention is carried into effect as illustrated, by way of example, in the accompanying drawing in which:

Fig. 1 is a perspective View of the connecter clamp showing it as detached:

Fig. 2 is a perspective view of Va gasket employed in conjunction with the connecter clamp shown in NFig. 1:

Fig. 3 is a View in side elevation of the connecter showing it Vas applied to the binding post of -a battery:

Fig. 4 is a detail in section as seen on the line 4--4 of Fig. 3 with parts in elevation depicting the manner in which the connecter clamp and gasket shown in Figs. 1 and 2 serve to seal the joint between the binding post and the adjacent surface of the top wall of the battery box: Fig. 5 Vis a plan View of the connecter showing is as applied.

Fig. 6 is a view of a modified form `of the connecter clampV showing it in side elevation with a portion broken away:

Referring `to the drawing more specifically Aindicates generallythe connecter clamp, B designates a binding post of a battery on which the connecter clamp A is designed to be mounted,

and C denotes a gasket designed to be positioned to encircle the base of the post B and to be associated with `the clamp A with the gasket interposed between the clamp and the top wall of the battery box at the base of the binding post B.

As here shown the clamp A embodies a substantially U-shaped body portion including an arcuate end member l formed to telescopically receive and to encompass the upper end portion of the terminal B. The clamp also embodies a pair of spaced leg members 8 and 9 formed in continuation of the side portions of the arcuate end member l. A bolt I0 is passed through -aligned openings H formed in the leg members 3 land 9 in longitudinal slidable engagement with the latter;` a head I2 on the bolt bearing against a recessed flat surface I3 on the outer side of the leg vmember 8 with one edge of the head I2 abutting a shoulder I4 on the leg 8 whereby the bolt will be held against rotation when the head I2 is seated on the recessedsurface I3.

A nut I5 is screwed on the threaded end of the bolt I0 to bear against the outer face of the leg 9 as particularly shown in Fig. 5 and when tightened on thel bolt'l IIJ serves to clamp the arcuate end portion 'I into tight engagement with the post B.

Formed on the leg y3 and extending in continuation thereof is a ferrule I6 in the form of a split cylinder within which is mounted in a usual fashion the terminal of an electrical conductor I1, by which construction the conductor will extend in continuation of one of the leg members of the clamp.

'I'he binding post B comprises the conventional terminal of the type of Storage batteries employed in the electrical systems of motor vehicles, being frusto-conical in form and having an annular flange I8 at the base thereof which seats on the surface of the top wall D oi the battery box. The inner periphery of the arcuate end portion 'I of the clamp is tapered to conform to the upper end. portion of the binding post B.

Formed on the clamp A and protruding from the under side thereof as shown in Figs. 1, 3, 4 4

and 5, is a series of spaced prongs I9 which arel curveddownwardly and outwardly from their intersection with the lower margin of the clamp as particularly shown in Fig. 4. These prongs are designed to serve a'two fold purpose, namely to act as spacers to retain the clamp A in an elevated position on Athe binding post B and in spaced relation to the top wall D of the battery box and at the same time serve to tightly compress the gasket C which is interposed between the clamp and the top wall of the battery box.

The gasket C is formed with a circular opening 20 to accommodate the binding post B and is made of felt or similar soft fibrous material which when applied is saturated with an oil, grease or other anti-corrosion substance, and when applied is positioned around the base portion of the binding post to overlie the base flange i5 of the latter as particularly shown in Fig. 4.

The outer margin of the gasket C is formed with a bevel 2l on which the out-turned lower ends of the prongs E9 seat and whereby on pressing the prongs downwardly on the margin of the gasket the latter will be caused to snugly conform to the flange I 3 and eiect a tight seal of the joint between the binding post and the top wall D of the battery box, and whereby the escape of acid fumes around the juncture of the post and battery box is effectively prevented.

As a means for affording adequate protection against the possibility of acid fumes rising against the under side of the ferrule I6 and the bolt IG, the gasket C is formed with a side elongation 22 to overlie the portion of the surface of the battery box extending beneath the ferrule i6 and bolt lll, as particularly shown in Figs. 3 and 5.

In the application and operation of the invention the saturated gasket C is iirst positioned around the binding post B to snugly conform to the base portion thereof and to overlie the flange i8. The clamp A is then positioned to encompass the upper portion of the binding post B with the prongs i9 bearing tightly against the marginal portion of the gasket to tightly press the latter in place whereupon the clamp is caused to tightly engage the binding post by tightening the nut i5 on the bolt l.

The prongs will then also serve to dispose the clamp A in an elevated position relative to the top surface of the battery box thereby supporting the conductor Vl and its engaging ferrule I6 clear of the battery box, and also positioning the clamping nut i5 in such spaced relation to the battery box as to enable its easy adjustment on the bolt ID.

By connecting the conductor Il to extend in continuation of one of the leg members of the clamp the arcuate member 'l of the clamp will be free to ex throughout its entire length and whereby a maximum of resiliency is afforded which serves to facilitate application and removal of the clamp as compared with the type of U-shaped terminal connection in which the conductor is aiixed to the connected portion of the clamp.

In the construction shown in Fig. 6 an apron 23 is formed on the lower margin of the clamp A to serve as a spacer in lieu of the prongs I9, and which apron functions in a fashion similar to that of the prongs in engaging the gasket C and also in spacing the clamp from the battery box.
