ELECTRICAL CONNECTOR.
Specification of Letters Patent.
Patented May 25, 1909.
Application filed November 21, 1906. Serial Ho. 344,487.
Electrical Connector, of which the fo owing is a specification.
The object of my invention is to provide a simple and inexpensive, but efficient, electrical connecting device, particularly adapted for use in making ground connections on pipes and cables, and especially for making electrical connections to lead cables to ground them.
In the accompanying drawings Figure 1 is a erspective view of my connector detac ied Fig. 2 is a side view of the connector attached to a pipe or cable; Fig. 3-is a crosssection on the l 1ne33, Fig. 2 Fig. 4 is a perspective View; and Fig. 5 is a cross-section of a modification. I
I take a'strip of copper or other suitable conductin material and of a convenient width, and bend it u into about the shape shown in Figs. 1 an 4, that is to say, into the form of a clip with a hooped part 5 adapted to be fitted to and to em race the pipe or cable 4, and with two wings or free ends, 6 and 7, with. which I combine connecting means to clamp the loo ed part of the con- 1 nector on the pipe or ca le. instance these connectin means are shown as consisting of heads bolts 8 passing through holes 9 in the wings 6, 7, and rovided' with screw nuts 10. Instead of av- In the presenting closed holes for the bolts in both win s as shown in Figs. 1 and 2, I refer to make the holes in the wing 7 in the orm of notches 19, as shown in Fi s. 4 and 5, and to upset the ends of the b0 ts at 18 to prevent the nuts from being lost, as will be readily understood.
.One of the Wings, 6, has its outer ed e curled or rolledover inward to form a tu e 1 l, lying in the direction of the length of the This tube 11 is of a diameter to form a socket to receive with a snug fit the bared end of the electrical conductor 12,
which is to be soldered to the clip. By this provision of a socket lying in the direction of the length of the pipe or cable, the conductor 12 can be more conveniently connected up than where the socket is at right angles, as is the common way. And the fact that the socket is open at opposite ends makes it further convenient to attach the conductor at either end, and at the same time the wireman is enabled to readily see that he gets his wire inthe full length of the socket to make a thoroughly good electrical and mechanical joint. p
The Wing 7 is of a length to enable its outer end to bear a ainst the'outer face of the tube 11 at the mi die of the tube, when the two wings are drawn up toward each other. This will tend to prevent the corners 13 of the clip from being forced into a soft lead cable, as might occur, to the injury of-the cable, if the wing 7 were short enough to pass under the tube 11 and the bolts and nuts 8 and '10, were to draw the wings too close together.
I claim as my invention- 1. An electrical connector, comprising a clip to embrace a free ends, one of w lch has a Wire receiving socket, while the other free end is adapted to bear against the middle of said socket, and bolt and nut means passing throu h the free ends to draw them toward each ot er.
2. An electrical connector, corn rising a strip of sheet metal bent into the orm of a clip to embrace a pipe or cable and having free ends, with bolt and nutmeans to draw the free ends toward each other, one of said free ends having, beyond the bolt and nut means, a projectingface against the outer edge of which said other free and may bear as the bolt and nut means are tightened, as and for the purpose described.
in testimony whereof I have signed my name to this specification, in the presence of two subscrib' Witnesses.
