removing the insulation about the end thereof for a distance equal to the width of ,said clamp and then inserting the same within the clamp between the flanges 9. The cap C is.

then placed in position,and solder or other material is poured into the chamber 13 through the holes 3 in a liq'uid state, the liquid being of suohconsistency that it will flow freely and lill in all of the open space in the cham- !,D ben-17, thus uniting the clamp and main wire into one solid mass. If, perchance, the wire should be slightly smaller than the open space-between the ilanges 9, putty or some 'other pliable material is worked around the |15 outside of said wire to prevent the liquid from escaping from the chamber 17. After the"`molt`en metal has cooled the clamp is secured in position on the arm 8 and a rigid and'permanent connection is made between said mainwire and the binding-post A. From the 4main binding-post the current is divided and passes through the fuse J upon Tone side through the terminal post E into the branch wirel `11 and 'there conducted to its point of z5 distribution and on the other side through the fuse I, binding-post-E, and branch wire 10. The method heretofore in general use lfor making'solder connections for branchcutouts has been tb first strip the-insulation from the main a d branch Wire, and then after scraping an cleaning the same they have been coiled around each other, after which 'heat is-applied to said coiled part and when sulioiently heated have been' secured together Aby means of solder. This operation v'hns'.been found defective in that the wires become more or less smutted by the heating- 'ilame'and prevents the solder from inakinga perfect connection, which imperfect connection'p'ejrinits thewires to become loosened in time, 'thereby creating a resistance through Y the arcs that are formed and frequently when the Iwires are adjacent to combustible material causes 'a re; but by the use of our device these diiculties are overcome, the main wire being inclosed within the, clamp and cannot-be smutted, but a clean surfacev is presented to the solder, and the resulting connection is a positive and permanent one, the wires and clamp becoming a. single unitary lmass.

' A modified form of clamp is shown in Fig. 5, in which asolder-chamber is formed in both theparts- B and C.

In Fig. 6 we have illustrated a combined 'clamp and binding-post, in which it is de- 'signed` to attach the main wire to said post mechanically withoutI the aid of molten metal.

This is accomplishedby providing the open- 6o ing 26 in the binding-post A and theset-screw Y, which impinges upon the main wire after sof vestes it is inserted within said opening, this binding-post being secured to the plate Gr by setscrews entering the tapped holes 18 and '1.9.

In Fig. 7 we have illustrated a clamp which 65 is secured directly to the base 8 of the binding-post A by the screws 20, thus obviating the use of the cap C. (Illustrated in Fig. 2.)

By the improved construction of this cutout currents of electricity may be deilected by the use of any standard make of non-arcing fuses through the branch Wires Without the usual difculty of installment. Either of .the forms of lugs or clamps herein shown can be used with other forms or kinds of bindingposts, and we do not, therefore, limit ourselves to the exact construction of the posts and clamps as herein shown.

There are many minor changes and alterations that can be made within our invention 8o aside from those herein suggested, and we would therefore have it understood that we do not limit ourselves to the exact construction herein shown and described, but claim all that falls fairly within the spirit and scope of our invention.

Having fully described our invention, what we claim as new, and desire to secure by Letters Patent, is

1. In an electric cut-out, the combination 9o with a binding-post; of a two-part clamp designed to be securedover the main wire, one of said parts being arched and recessed to form as'older-chamber, the ends of which com'- prise fitting-ribs, lthe other of said parts being provided with solder-holes opening into said solder-chamber; means for'secnring said parts together over 'said Wire; and means for fastening said clamp to said binding-post, all constructed substantially as described.

2. In an electric cut-out, the combination with the basevG; of the binding-post A attached to said base; binding-posts E attached to said base and having means for securing branch Wires thereto; fuses I and J secured to said binding-posts A and E;- and a two-part clamp designed to be secured over the main wire, one of said parts being arched and recessed to form a solder-chamber, the lateral sides of which form a tting-rib; means for 11o securing said parts together over said wire; and means for fastening said clamp to said binding-post A, substantially as described.

In testimony whereof we have signed our names to this specification in the presence of 1 x5 two witnesses.
