Improvements in Wire Connectors, (Case I N 0. 2,281,) of which the following is a specification.

This invention relates to devices for electrically connecting the adjacent ends of two wires; and its object is to provide a connector which can be easily made from sheet metal at a low cost and practically without any waste. Y

The connector most generally used, especially in telegraph-lines, is made of two short tubes flattened on one side, with the flat portions brazed together. The end of each wire is passed through one of the parallel tubes, one in one direction and the other in the opposite direction, and the short end of each wire is then wound around the standing portion of the other. The whole is then pulled taut, and solder is run into the tubes to secure the wires and insure a good electrical connection. s

In my invention I bend a sheet of metal into such shape as to form two parallel tubular receptacles forthe ends ofthe wires. I am aware that this is not broadly new; but my specific modifications ofthe general idea are believed to be novel and patentable. In one form the sheet is cut into two rows of narrow parallel strips extending from each side in toward the middle of the sheet. These strips or fingers are then bent in opposite di rections, alternately forming a series of rings on each side of the sheet, united by the integral middle i ortion thereof. In another modification t e sheet is formed into a tube, which then has a row of holes punched along each side, and the sides are then forced inward until the portions between the holes pass through the holes in the opposite side. wire is then run through the protruding loops and the singled tube has become a double one. a

The invention will be better understood by reference to the accompanying drawings, in which Figure 1 shows a sheet of metal cut'into a double row of strips or fingers. Fig. 2 is a perspective view showing fourpairs of strips or fingers bent outwardly. Fig. 3 shows the completed connector. Fig. 4 shows the punched tube for making the second form of connector. Fig. 5 shows the punched sides bent inward, and Fig. 6 shows the completed connector.

In Fig. 1 the sheet A has two series of parallel slits a, running from opposite edges of the sheet in toward the middle, where an integral longitudinal ,portion a is left. Alternate pairsof fingers l 2 arebent in opposite directions, as clearly shown in Fig. 2 being curved into semicircles with their ends adjacent,

thereb forming rin s1 '11 in lanes perpendicular to the axis 5f die i ecegtacle. When all the fingers have been so bent, the structure presents the appearance shown in Fig. 3, being that of two parallel skeleton tubes slit along the outside and integrally united along their adjacent sides.

When the wires are slipped through such a connector and wound in the usual fashion,

' solder can be'readily run in through the 0 en spaces between the fingers to give a good e ectrical connection. Moreover, thefingers can be clamped upon the wiresbysuitable pliers, if desired. A

Fig. 4 shows a sheet-metal-tube B, having 1 arow ofholes bpunched in each side, the holes in each row standing opposite the intermediate solid portions b in the otherrow. I/Vhen thesepunched sides are forced inwardly, as shown in Fig. 5, the portions 1) pass through the opposite-holes b and protrude in the shape of loops, as seen in Fig. .6. A pin 0 is then run through these loops. The'tube B has now become two parallel integral tubes B, forming a strong and eflicient connector.

These connectors can be easily and cheaply made and afford a strong and integral metallic connection btween the wires.

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

1. A wire-connector consisting of two parallel sheet-metal tubular. portions with a wall of metal between them integrally connected therewith on both sides of the plane of their axes.

2. A wire-connector consisting of a single piece of sheet metal formed into two cylindrical receptacles with a wall of metal. separating them and integrall connected thereto on opposite sides ofthe p ane of their axes.

Q seams 3. A Wire-connector consisting of a strip of metal having integral circular portions extending alternately on both sides thereof.

4. A Wire-connector consisting of a strip of metal having pairs of integral curved fingers extending from each sidethereof. ingwith those in the other. v
