BINDING-POST.

Specification of Letters Patent. Patented Sept. 13 1910.

Application filed. June 22, 1910. Serial No. 568,262.

To all whom it may concern:

lie it known that I, Tnouns E. MURRAY, a citizen of the United States, residing at New York, in the county of New York and State of New York, have invented a certain new and useful Improvement in Bindin Posts, of which the following is a speci cation.

The invention relates to binding posts or wire connectors for circuit conductors, and consists in the construction, more particularly set forth in the claims, \vherebv the device is adapted to hold wires of differentgage and rendered simple and inexpensive.

In theaccompanying dra\vingsl igures l and 2 are side elevations of my binding post. F ig. 3 is an elevation with the heat and wire in cross section. Fig. 4 is a vertical cross section. Fig. 5 is a top view, and Fig.6 is an elevation, of the head and shank separately: and Fig. 7 is an end view of the sleeve.

Similar letters of reference indicate like parts.

.The shank A and head B are referably formed integrally of sheet metal: suitably shapedand bent, so that the shank is bifurcated. The head is elongated and semi cylindrical. The width of the groove in the head is to be sutlicieut to receive the largest size wire which the device is intended to hold, and may be made V-shaped atthe bottom, as shown at C. The sleeve D may also be made integrally of sheet metal, bent in cylindrical form, and fits on the shank. On one edge, or, preferably as -here shown, on both edges of the shank are may be formed similar pairs of recesses H,

I, J, the recesses H being smaller than the recesses G, and the recesses I being smaller than recesses H, and the recesses J smaller than recesses I. In this way, I provide, as here shown, six pairs of recesses, progressively smaller in size. In the upper edge of the head 'B and in roximity to and on each side of the shank A are formed pairs of notches K, L.

In using the device, the wire M is seated in the groove in the head B. The sleeve D is then placed on the shank and adjusted with either end downward, so that a recess, as J, of proper size correspondin Y to that of wire M comes over said wire. T iosleeve is then moved down so as securely to clamp the wire 1n place in said recess and between the sleeveand the head. l/Vhere the wire is, as shown in the drawings, of relatively small diameter, the notches K, L in the head permit this downward adjustment of the sleeve. A headed screw N is then inserted through an opening in any suitable sup ort, as 0, into the shank, and set up, thus olding the sleeve in adjusted positlon upon the wire, and also securing the whole device to the support.

I claim:

1. A binding post comprising a bifurcated shank, a sleeve thereon having a plurality of pairs of oppositely disposed recesses in its edge, each palr of recesses differing in size from the recesses of the other airs, and the wire to be held being receive in a pair of recesses of corresponding size and between said sleeve and the bottom of the shank, and means for holding said sleeve in adjusted position upon said wire.

2. A binding post comprising a bifurcated shank, a sleeve thereon having in each edge a plurality of pairs of oppositely disposed recesses, each pair of recesses differing in size from the recesses of the other pairs, and the wire to be held being received in a pair of recesses of corres onding size and between said sleeve and tie bottom of the shank, and means for holding said sleeve in adjusted position upon said wire.

3. A binding post comprisingI a bifurcated shank, an elongated grooved ead integral therewith and provided with notches in its edges adjacent to said shank, a sleeve on said shank having a plurality of pairs of oppositely disposed recesses in its edge, each pair of recesses difiering in size from the recesses of the other pairs, and the wire to be held being received in seid recesses end between said sleeve and the bottom of said shank, and means for holding said sleeve in adjusted position upon said wire.

II'1 testimony whereof I have aflixed my signature in presence of two witnesses.

THOMAS E. MURRAY.
