WIRE CLM?.

Application filed February 20, i920. Serial No. 360,233.

To ali whom it'may cof/wem:

Be it known that I, JoHANNss FRANoIsoUs SCHLEPER, a subject of the Queen of the Netherlands, residing at Amsterdam, the Netherlands, have invented certain new and useful improvements in Wire Clamps, of which the following is a specication.

The invention relates to the provision of a cheap and reliable clamp for electric Wires by which soldering of the Wires may be completely dispensed with.

This and other features of my invention 'will be more readily understood by the folm lowing description., reference being `had to the accompanying drawing in which:

Fig. i shows a longitudinal sectional View a wire cian-'ip constructed in accordance with the invention;

F is an elevation of a branch or dis- "ributing box with two wire clamps each for our Wires, tlieccover plate being resectional View, partly in elevau tien,

' sections-i View along the ntine 1 '7 oie-a second embodiment of sectional View of e,

d effe passed lengthwise into tuoni member i. The Wall of the 'i is provided wits some s mrough i800 slots 4i opening into its bare wire ends are bent v are received in .f 1 i the niemeer i 1 nte. it is obvia t ins disposed and 7, the ring 6 and the bottom portion of member 1, thus ensuring` the required insulation.

It will be. understood that the ringr 6 may be integral with nut 71, in which case the lock nut 8 may be dispensed with.

Fig. 2 illustrates how the described wire clamp may be used for branching two cables 14 and l5 of a lighting main. This figure need not further be explained.

in manv instances it is vervconvenient to replace the rigid ring 6 by a Sleeve or a can of thin sheet metal. lf such a sieeve or can is forced tightly on the bent'over bare i wire ends, it is deformed in such a manner that it ensures a perfect electrical contact 'with all Wires, even when the latter here different thicknesses. This cannot ai'ays be realized with a rigid clamping ring.,

A wire clamp comprising such a thin sheet metal cap isiliustrated in Figs. 3 and The bare ends c25 the cut cables 2 are ik pessed into a tubular member and bent i through about i800 through axial slots 'opening' in the top 'ieee 3. Passed o tubular member l and the bent ov ends 2 is e can ld of 'verv thin sheet bray so :formed 'that bottom does not thi, top -face of member 'i when is simply put in piace, The said c crcibiy pressed on the bare Wire eens of screw il extending; n the bottom 'the csp en ne tubo it; member (iii covering is lirmly pressed against the "Walls of the holes, perfectly tight joints are obtained.

The Wire clamp shown in Fig. 5 is provided with a porcelain cap 9a screwed on the tubular member l.

Having now particularly described and ascertained the nature of my said invention and in what manner the same is to be performed, l declare that what ll claim is:

ll. An electric wire connector comprising in combination a member upon which the ends ot Wires are bent; arms extending from said member having slots between. them through which the Wire ends pass, said arms having screw threads thereon; means for engaging and holding the Wire ends in bent condition; and a4 screw threaded member engaging the screw threaded arms and. adapted when adjusted to bear down and clamp the last named means in position to hold the Wire ends.

2. An electric Wire connector comprising in combination a member having an upstanclinp; collar over which the ends of Wires are bent; arms projecting from said collar and having spaces between them to receive the Wire ends and hold the same spaced; means surrounding said arms and adapted to engage the bent ends of the wires and electrically connectingthe same; and means engaging said arms and also engaging said means surroundingthe arms for camsing` the latter to clamp the Wires and ensuring good electrical connection.

3., An electric Wire connector, comprising a member having an upstanding collar over *which the ends of the Wires are bent, arms projecting trom said collar and having1 spaces between them to receive the Wire ends and hold the same spaced, means surroundnasi-raar ing said arms and adapted to engage the bent ends ci the Wires and electrically connecting the same, said means being deformable to lit Wires of different diameters, and means engaging said arms and also engaging said means surrounding1 the arms for causingf the latter to. clamp the Wires and insure good electrical connection.

4. An electric Wire connector comprising in combination a hollen tubular member through which the Wires pass and upon which the bent ends ot Wires are disposed; a metal member adapted to simultaneously engage the bent ends of all the Wires to make electrical contact therewith, said metal member being;I yieldable so as to securely engage wires ot a number of sizes at the same time; and means for clamping the last yieldable metal member in eective position.

5. An electric Wire connector, comprising a hollow member through which the wires pass and upon which the bent ends of the Wires are disposed, 'said member being closed at its bottom by a Wall perforated for the passage of the Wires, arms projecting from said hollow member and having spaces between 'them to receive the Wire ends and hold the' same spaced, means surround'- ing said arms and adapted to engage the bent ends of the wires and electrically connecting the same, and means engaging said arms and also engaging said means surrounding the arms for causing the latter to clamp the Wires and insure goed electrical connection.
