Application filed December My invention relates to electric circuit connecters. More particularly-it relates to con-.
necters of thetype especially'adapted for use in connecting the so-called tap or ground wire of electrical apparatus to'ground as, for example, through means of a pipeline, a rod, or the like, as is customary in connection with telephone apparatus-or lightning arresters.
Devices of the above generalcharacter are well known but. are complicated or ineffective, not substantial in struoture,.unreliable in maintaining-a permanent ground connection, not eflectively adjustable for use in connection with pipes, rods. and the like of different s sizes-and expensive.
Among the objects of my invention are to provide a connecter which avoids the above objections. However, the invention will be more readily 1 understood from the accompanying specification and claims, reference being had to the accompanyingdrawing,'. Fig.
1 of whichshows in perspective aground connecter comprising the features of the invention, and Fig. 2 of which shows thedevice of Fig. 1 in section. Fig. ,3 is a modified form of the device.
Referring to the drawing more in detail, it
willbe seen that the conneeter is shown connecting two conductors 2 and 3. In this connection it may be assumed that the conductor 3 is a grounded line such as a water pipe. The
clamp comprises a pair of jaws 4' and 5,; du-
plicates of each other. The jaw 4 is provided 7 on one side with aheel element 6. Similarly, 85 the jaw 5 isprovided on the opposite side as may be readily seen by referring to ig. 2,
I with a corresponding heel 7. The'jaw 5 is providedwith a notch 8 for receiving the heel 6, while the jaw 4 isprovided with a notch t).
vfor receiving the heel 7 It will be seen that the lower ends 10 and 11 of the jaws are threaded for receiving the nut 12 which latter is tapered, the larger opening being on the upper side, Fig. 2. The object of the heels6' 65 and 7 and of the notches 8 and 9 is to properly line up the jaws 4 and 5 with respect to each, other so that therthreads will properly line up. It will be seen, therefore, that by means of the nut 12 the jaws 4 and 5 may be tightly clamped about the conductor 2 as shown,

thereby insuring a tight ,and effective connection between the aws and the conductor. Such a connection can be .easily, efi'ectively and quickly set up. Furthermore, this type of construction makes it unnecessaryto have a the. end of the conductor .2 threaded. The
at equal intervals, but at unequal intervals as 1 indicated. With this arrangement it is possible to run the strap around the pipe?) with two of'the perforations 15 in juxtaposition betweenthe jaws 4 and '5 as shown inFig 2. When the strap is thus brought into position about the pipe-3 and threaded by the bolt 13 the strap 14 may be tightly drawn abeut the pipe into effective electrical connection with the pipe and with the jaws by tightening the nut 16 of the bolt 13, thereby drawing the j aws together, thus effectively, simply, and
substantially grounding the conductor 2 with the pipe 3. It is obvious that with a connecter of the foregoing character connection 7 may thus be made between the conductor and so the pipe regardless of the size of the pipe, in-
asmuch as the size of the loop formed by the.
- It is obvious that "a connecter device of the foregoing character can be easily and cheaply manufactured, and quickly, easily 'and eflectively put, together anywhere and at any time underaimost any conditions with a minimum amou of effort and consumption of time. It will be understood that in form- ;ing the loo abo'utthapipe 3 .it may be con- 4 venient," a er the proper perforations are brought into juxtapositionfor receiving the bolt 13, tojcut off the ends of the strap below the bolt 13. I
In the/modified form of the device shown in Fig 3, it will be seen that the jaws are 7 iormei so thatthey may be brought actually 10o against the conductor The face of the jaw is cut away so as to permit the'strap that binds the conductor 2 to pass into the jaws without interfering with the direct contact of the jaws and the conductor 2. 7
With the ty e of device shown in thedrawing, it is evid nt that both of the jaws are identical, which of course simplifies the man-- ufacture. These jaws are so constructed that any two of them may be brought together and assembled to form the connecter of the invention. While in Fig. 1 I have shown an ordinary form of nut 16, a wing nut may be substituted for this-type of nut. In the event that the conductor2 constltutes a conduit for a cable orconductonvthe conductor itself may be directl secured and soldered, if necessary, direct y to the strap that binds the ground conductor3 as indicated in v dotted lines in Fig. 2. i
"It will be understood that while I- have elected to disclose my invention in, connection ,with a specific form of construction, I 'do not wish to be'limited to such construction inasmuch as in view of the disclosure, variations may be made without departing from the s irit of the invention or the scope oitthe c aims appended hereto. I
What I claim as new and desire to secure by LettersPatent of the United States, is 1. An electric connecter having in com ination a pair of jaws, means for'clamping the ends of said jaws to an electric conductor, and a strap of conducting material projecting in the form of a 100 from between the jaws at the other endof t e connecter whereby'an electric conductor may be inserted through said loop and means for clamping the loop about the conductor-whereby an electric connection may be established between the two electric conductors through said connecter.
2. An electric connecter having in combination a pair of jaws, means for clamping the ends of said jaws to an electric conductor, a
