Claims. (01. 179-259) This invention relates to certain new and useful improvements in connecters and particularly to the typefor-connecting cables or conductors to the terminals or posts of storage batteries.

The primary object of the invention is to provide a battery terminal connecter embodying a sleeve to be placed in. enclosing relation to a battery terminal post combined with a clamping ing screw from the frame, but to prevent de- 7 connecter. I P With the above and other objects in view that will become apparent as the nature of the invention is better understood, the same consists in the novel form, combination and arrangement of parts hereinafter more fully described, shown in the accompanying drawing and claimed.

In the drawing:-

Figure 10 is a cross-sectional view taken on .line 10-10 of Figure 2, showing the key hole' slot in an end wall of the frame for cooperation with a keyor flattened portion on the clamping screw adjacent the'he ad permitting removal of the clamping screw from the frame of the 'con- Figure 11 is a cross-sectional view similarto Figure 9 showing the substitution of clamping ribs for spurs: and

Figure 12 is-a topplan view showing a chromium plated lead or other sleeve upon the end of a conductor inserted in the tube portion of the connecter.

Referring more in detail to the accompanying drawing, there-is illustrated a battery terminal connecter 15 including a cylindrical sleeve 16 receivable upon the terminal or post P of the battery B as shown in Figure 2. A cable or conductor receiving tube17 is carried by one side of the sleeve 16 by means of a connecting neck 18 and said tube is longitudinally split at its outer side as at 19 to permit the positioning of a conductor end -therein and relative movements between the split parts of the tube 1'7 for clamping engagement with the conductor.

The side of the sleeve 16 opposite the tube 1'7 is open and at the open side of the sleeve there is provided a frame including .parallel side walls 20; a bottom wall 21, an outer end wall 22 with oppositely disposed inwardly directed ribs 23 carried by the side walls 20 in spaced relation to the outer end wall 22 providing a rectangular 1 pocket 24.

The clamping screw 25 of the connecter is interlockingly and removably associated with the frame portion, being provided upon one end with a polygonal head 26 with the shank of the screw adjacent the head unthreaded and oppositely flattened as at 27 to provide a reduced key portion. A clamping plate28 having an arcuate clamping face is swivelled as at 29 upon the threaded end of the screw 25 and said screw passes.

. key portion 27 of the screw and is placed over the open side of the connecter frame, the nut 30 registering with the rectangular pocket 24 and the end wall 22 of the frame provided with.

an upper edge opening key slot, 31 through which t e key portion 27 of the clamping screw 25 When the clamping screw is e ged with the frame of the connecter, the nut confined within the pocket 24 while the c mping plate 28 is located betweeen the ribs 23 and closed side of the sleeve 16 as illustrated in Figure 6. Upon rotating the screw 25, the same threads through the nut 30 that is prevented from rotation and displaces the key portion 27 of the clamping screw with respect to the key slot 31 in..the end wall 22 of the frame, thereby moving the clamping plate 28 in a direction toward the open side of the sleeve 16 to the position shown in Figure 1 and at which time the same may be placed upon the battery terminal post P as shown in Figure 2. The key slot 31 in the end wall of the'frame maintains tery terminal post for anchoring the connecter thereto, and in lieu of said spurs 28a, the clampingplate 28 as shown in Figure 11 is provided with ribs 28b for biting engagement with the battery terminal post. The pockets or crevices resulting from the assembly of the connecter frame and clamping screw may receive grease or lubricant which acts to eliminate corrosionaround the battery post.

In the form of invention illustrated in Figure 12, the connecter 15ais .constructed similarly to the connecter 15 shown in Figs. 1 to 11 with the exception that the closed side of the connecter opposite the frame portion thereof is open and the sleeve portion 16a carries a transversely extending tube portion 17a that receives a chromium plated-lead or other tubing 32 se-.-' cured to one end of the conductor 33. The tubing 32 extends through the outer open side of the sleeve 16a for direct engagement by'the clamping ates 280, the outer side of the tubing 17a carrying inwardly pressed transversely extending ridges or beads 34 for binding engagement with the chromium plated lead or other tubing 32. g

From the above detailed description of the invention, it is believed that the construction and operation thereof will at once be apparent and while there are herein shown and described the preferred embodiments of the invention, it is nevertheless to be understood. that minor changes may be made therein without departing from the spirit and scope of the invention as claimed.
