Application filed January 10, 1927. Serial No. 160,017.

This invention relates to wire connectors or clamps for uniting and electrically connecting current wires, although applicable to other uses, and the object of the invention is to afford a tight mechanical clamp for holding the wires against displacement, and at the same time insure a close electrical contact between the wires and the connecting or clamping member, so that the latter will serve in the capacity of a conductor.

A further object pertains to the provision made for connecting wires of different diameters, or for clamping the member to a single wire, as the case may be, as well as to its use in connection with wires of uniform diameter.

The device is so designed that it may be readily stamped out of a sheet or plate of metal, or other suitable material, if any, and to the means provided for holding the parts in clamping relation with one another.

Further objects will appear from a detailed description of the invention, in conjunction with the accompanying drawings, wherein Figure 1 is a perspective view of the connecter in its preferred form;

Fig. 2 is a sectional view of the same;

Fig. 3 is a rear face view of thefemale member,

Fig. l is a sectional view showing a slight ly modified form of connecting screw;

Fig. 5 is a view similar to Fig. 4, showing the male clamping member tilted to clamp a single wire;

Figs. 6, 7 and 8 are views in section showing modifications in the formation of the male member; and

Fig. 9 is an elevation of the device used in connection with a wire splice.

The wire connecter or clamp consists of a male member A and a female member B. Each of the members is of rectangular shape and preferably stamped out of a sheet or late of conducting metal, such as copper. Both of the members are preferably of equal length, but the femalemember is preferably of greater width than the male member.

The male member is provided on each of its side edges with an inturned flange or tongue 10, which, as indicated in Figs. 1, 2, 4: and 5, may have a smooth inner acting edge; or said edge may be configured, as indicated in Figs. 6, 7 and 8, to present either a slightly concaved face 11 or a V-shaped channeled face 12, or a series of serrations 13, as the case may be.

The coacting female member is provided along each of its side edges with a groove 14 of a size and shape to receive the tongues, which grooves may be provided with slightly rounded base walls 15. The base walls of these grooves, however, may be otherwise formed, as, for example, by following the general form which the male member has taken in Figs. 6 to 8 inclusive. The rear outer face of the female member 13 may be provided with a cross channel 16, as indicated in Figs. 1, 2 and 3. or said face mayv be plain, as indicated in Figs. 4 and 5.

The clamping members or plates are held in clamping relation by the provision of a screw 17, which is disposed centrally of the plates and in intermediate relation between the tongues and grooves. The screw is provided with a head 18, and the male member in each instance is provided with a smooth bore 19, which permits the screw to be freely entered through the male member. The female member may be provided with a threaded bore 20, as indicated in Figs. 4 and 5, or the female member may be provided with a smooth bore 21,-as indicated in Fig. 2. lVhere a smooth bore is employed, the screw must of necessity be used in conjunctionwith a nut 22, which preferably occupies the channel 16, which is thus held against turning while the screw is being drawn up, although a similar nut 23 may be employed in conjunction with the threaded bore 20 in the female member, in which case the nut will act merely as a jamb nut to assist in preventing the loosening of the screw.

Other variations in detail may suggest thennselves, and it is not the intention, unless otherwise indicated in the claims, to limit the invention precisely to the forms indicated, since the principle of the invention is one which permits of its embodiment in other modifications.

In use, the

wires

24 and 25 are laid within or wires 26 and 27, as in Fig. 9, may be spliced together by leading the oppositely disposed ends through the wire connecter, and afterwards twisting or coiling the ends as indicated. Wires of different diameters may be connected, or a single wire may be clamped, as in Fig. 5, in either of which latter cases the male member is tilted more i or less, and one of the tongues will act as a fulcrum, lying within its channel in the female member, while the other tongue is elevated toward the mouth of the channel, to a greater or less degree.

In these circumstances, although the male member is tilted, it will still retain full engagement with the female member, so that displacement of the parts will be prevented, and the screw will tend to bear down the male member sufficiently to effect a firm and rigid clamping of the parts. The male member thus acts on the lever principle under the influence of the screw, so that a full clamping effect will be secured irrespective of variations in the size of the wires, and even to the point of permitting a complete elimination of one of thewires.

By employing coacting tongues and grooves of the character indicated, the clamping members will be positively interengaged at all times, so that any lateral or r'otative displacement of the parts will be prevented, and the screw can be turned down as tightly as possible without any tendency to rotate the clamping members on one another, and without setting up any abrasive action against the surfaces of the wires, which are simply compressed and clamped by the interlocking action of the tongues and grooves.

The device as a whole is of extremely simple formation and may be readily stamped from copper or the like, which reduces the cost of manufacture to a minimum.

I claim:

1. A wire connecter, comprising two clamping plates, one of said plates being provided with a pair of tongues extending longitudinally of said plates and the second plate being provided with a pair of longitudinally extending grooves of a width to closely receive said tongues to enclose and clamp a wire running lengthwise along the base of one of the grooves, and means for drawing the plates into clamping relation.

2. A wire connecter, comprising two clamping plates, one of said plates being provided with a pair of tongues extending longitudinally of said plate and the second plate being provided with a recess on its outer surface and with a pair of longitudinally extending grooves on its inner surface of a width to closely receive said tongues, and a clamping screw extending through said plates and having a nut seated in the recess in said second plate.

3. A wire connecter, comprising two clamping plates one of said plates being provided on its inner surface with a pair of parallel spaced grooves and on its outer surface with a recess disposed between said grooves and the second plate being provided with inwardly extending tongues adapted to closely fit within said grooves, and a headedscrew freely entered through said second plate and extending through said first plate and having a nut adapted to be seated within and held by the recess in the outer face of said first plate.
