Application filed December 26, 1919. Serial No. a l-7,588.

one for attachment to each terminal of the.

.wires to be connected, with means whereby the members may be readily connected or disconnected to establish electrical communication between the wire terminals.

Tn addition to the foregoing this invention comprehends improvements in the details of construction and arrangement of parts, to be hereinafter described and particularly set forth in the appended claims.

lln the accompanying drawings in which similar and corresponding parts are designated by the same characters of reference throughout the several views in which they appear,

Figure 1 is a view in side elevation of a termmal connector constructed in accordance with my invention.

Figure 2 is a view thereof in longitudinal section.

Figure 3 is a view of the members of the connector shown in separated relation and Figure t is a detail section taken on the line l4t of Figure 2.

With reference to the drawings, 10 indicates the receptive member and 11 the penetrative member. The former consists of an inner metallic tubular member 12 which is provided at one end with a transversely extending pin 13, and with a threaded socket 14: at its opposite end in which to receive a threaded member or screw 15, the latter having a socket 16 in one end to receive the terminal 17 which may be an electric wire or electrical member to be connected. Movable within the tubular member 12 is a plug 18 having a reduced extension 19 formed at one end, the latter to enter the convolution of a coiled spring 20 also enclosed within the member and bearing at one end against the end wall of the member and its opposite end against the plug- 18.

sorted in one end of the tubular member21,

and a cap 23 in the opposite end, the latter to enclose the screw member 15 and to cover all metallic parts.

The penetrative member 11 consists of an inner metallic tubular member 24 which is of a diameter smaller than the inside diameter of the tubular member 12 whereby it may enter the same. The end of the member 24: is formed with a pair of longitudinally extending slots 25, each of which is formed with lateral circumferential extensions 26, the latter being also extended again as at 27 to lie parallel to the slots 25 and directed toward the terminal of said member 24:. The opposite end of the member 24 is formed with a threaded socket 28 in which to receive a screw member 29 similar to the member 15 to likewise receive the opposite terminal 30 to be. connected. A tube of insulating material 31 is embraced about the tubular member 24 but is faced from the slotted end thereof as shown, it however extending beyond the opposite end of the tubular member whereby a cap 32 of insulating material may be inserted therein to entirely enclose the screw member 29 and thus hide all metallic parts.

From the foregoing it will be apparent that in order to connect the members it is but necessary to insert the member 11 into,

pin 13 will thus be seated in the extension 27 of the slots 25 and further movement of the parts will be prevented. An absolute contact between the metallic parts is thus established.

While l[ have illustrated and described my invention with some degree of particularity.

I realize that in practice various alterations thereto may be made. it therefore reserve the right and privilege of changing the form of the details of construction or otherwise altering the arrangement of the corre lated parts Without departing from the spirit of the invention or the scope of the appended claims.

What I claim as new and desire to secure Letters Patent of the United States is:

1. An electrical connector comprising a tubular member of conducting material closed at one end, a pin extending diametrically thereac-ross, a second tubular member of conducting material adapted for insertion in the first and having a pair of diametrically opposed slots extending longitudinally thereof, each slot having a lateral offset adapted to receive the pin to lock the members against separation and resilient means urging the members apart to ensure retention in locked position.

2. An electrical connector comprising a tubular member of conducting material closed at one end, a pin extending diametrically thereacross, a plug provided in said member between the pin and the closed end thereof, a coil spring within the member and interposed between the closed end thereof and the plug, a casing of insulating material enclosing the tubular member, a second tubular member of conducting material adapted for insertion in the first, said second tubular member having a pair of longitudinally extending slots in opposed relation to each other each slot having its inner end formed with a lateral offset, said offsets extending in opposite direction to receive the pin, and a casing of insulating material enclosing the second tubular member but faced away from the slotted end thereof.

In testimony whereof I afiix my signature in presence of two Witnesses.
