' origini s. 430,914, Mmm si, im. Appie-.eu man 1.a nu eo, rss2. smnnmase .To all whom it may concerm' -Be it known' that I, HERCULES Smear., a

citizen of the United' States, residing at De troit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Electric Connections, of which thefollowing is a specification'.

In the drawings-Figure 1 represents a sectional elevation of myimproved electric connection or binding-post for electrical instrufnientsin which each part is held upon the wire belonging to the'part beneath it by a common binder at the tcp of the post. Fig.

2 isa vertical section of a terminal.

Heretofore tl. fastenin gs whereby wires, or

tensile cords, over which electric currents are passed, are connected to the various forms of binding posts o r to variousA forms .of apparatus, have always been a source of great annoyance to persons using electrical machines. Thus where sti wires are' employed-such as 4are used in the telephone-service or in the varions applications ot electricity for burglar- `alarms, medical. instruments of various kinds, andthelike-the ends are very apt to project Vand are unsightly and are liable to catch upon "the ngers or the clothes. Again, each time the circuit is broken or disconnected the wire has' to be unwoundor untwisted, and is thereby generally injured or broken.

It is the purpose of my invention to produceaterminal adapted for connection t0 a binding-post, or serving directly as a bindinglpost in connection with the object to which it is to be attached, the said terminal .remaining always on the end of the wire to be connected,

0 4' attached ends of the several wires or cables and to provide means whereby each terminal is held or clamped upon the wire belonging or terminal beneath it by a comwill be concealed from view and together with their terminals be securely clamped 1n position until they are required to be disconnected.

`To this end the reference letter-A designates a wire or cable and A its insulation winding of silk, worsted or fabric.

B is a terminal adapted to be permanently connected with one end of the insulated wire orcable. The .terminal B may be provided with 'a screw shank B' land it hasan oriilce or. perforation'b through which the end of the wird oroableis passedsothat it may be wound or coiled about this shank` as shown. Each wire has its own terminal B and when it is deaired to connect it with the binding post C it is only necessary to drop the terminal over the end of the binding post and screw the jam nut C' down upon it. Annmber of these ter- ,minal pieces B may thus be dropped over the binding post and be bound to adjacent terminals or to the post itself by means of the jam nut. As shown in the drawings the lowermost terminal maybe integral with the binding-post C and the other terminal pieces are centrally perforated to pass readily over the said post. If desired the terminals may be hollowedor cupped on one side. so that when one is clamped down upon another the end of the wire or cable coiled between adjacent terminals is completely housed or hidden from view. lt is preferable to so construct the terminals B that the lower portions of the nppermost ones will partly lap by or telesco the' upper portions of the ones immediate y beneath, the upper portion of each terminal being, for instance, rabbeted as shown at b' lalso hollowed or cupped on its under side,as shown, for a similar purpose whereby it not only'honses or conceals the end ot the wire 'attached to the adjacent terminal but, by partly telescoping the said terminal, it can be screwed down on the binding post so as to securely clamp both the terminal and its attached wire. .Itis obvious that by this construction of an electric connection or binding post and terminals the wires or cables can be readily attached r-orfdetached at will, without subjecting them to any liability of breakage or other injury.

1. vThe combination with an electric wire or cable, a binding post, and a terminal having a perforation through'which one end of the said wire or cable is passed, of a janifnut or binder screwed down on saidbindingpost in telescopic engagement with the terminal, whereby said terminal and attached wire or, cable are securely clamped, substantially as described.

2. The combination of a. terminal provided with a shank, an electric wire or cable having one end passed through a perforation in said terminal and coiled around its shank, and a jam nut or binder cupped or hollowed on its under side and adapted to telescopically engage the terminaland house or conceal the attached end of the said wire stantially as described.

3. In a binding post or electric connection, thecombination with a terminal having a perforation for passage ot' an electric wire or ca ble and hollowed or cupped on its under side to telescopically engage a. lower terminal and house or conceal the end of its attached wire or cable, of a jana-nut or binder cupped or holloWed/on its under side to telescopically engage the adjacent terminal and in turn conor cable, sullowitnesses.
