To all whom 'it 'may concern:

Be it known that I, CHARLES J. G. KEINER,- a citizen of the. Unlted States, residing at Baltimore, in the State'of Maryland, have invented' certain new -and useful Improvements in Connectors for Elect-ric Wires, of which the following is a specification.

This invention relates to im )rovements in connectors forclectricwires andhas particular reference to a two part and a two-way insulated connector'by whichthe ends of the conductor wires. may be brought -into electrical connection vand securely held against accidental displacement.

The device is particularly well adapted lfo'c use on motor cars where the connector is su h jccted to vibration in that the-use. of binding screws is avoided and all liabilitv of the connection being broken by the screwslworking loose.

The' invention is illustrated in the accompapving drawing, in whieh,-

l proved device o eratively connected.. Fig.

i 2 illustrates a si( e elevation 'of the two parts of the connector separated.- Fig. 3 shows' a .longitudinal sectional view of the device.

Fig. 4-illustrates a similar view of.a slightly modified form of device. 'Fig. 5 shows an end'view ofthe plug or insertible'memberof the connector, andFig. 6 illustrates acrosssectional viewof thedevice-fthesection bcing taken on the line 6 6 of Fig. 3.

Referring to thedra'wing by numerals, 1.,

.designates the socket-member ol the device and, 2, the plug-member.thereof, it being understood that the completed eonnect or com prises two parts, oneoi which fits into and en ages the other.`

he socket-member, l, comprises an inner metal bushing, 3, having a tape-red rer-.ess

or chamber, 4, extending longitudinally ,therein and a .central longitudinal iassage,

' 5, which extends from the outer en of said bushing and o ens-into the smaller end of said recess or e lamber. The inner or larger end of this bushing is .provided with a series ol' longitudinal slots, 6, forming spaced-apart.

fingers, 7, at said end, as'scen in Fig. 2.

A sleeve, 8, of insulating material surrounds thc bushing and forms a covering therefor. This sleeve is longer than the bushing and' projects beyond the outer end thereof while the inner end of said insulating sleeve is provided `with spaced-apart ingers. -9, which project over and 'coverthe'fin gurc 1 shows a side elevation of the im- Awhen the two members are connected,

cumferential rrooves, 25.

gers, 'Lol' the bushing. "lhese fingers, 9,-.are rovided with beveled ends, 10, whereby to orm acom'plcteand, tight covering when en# aging the socket member as will presently Je described.. A circumferential groove, l1, is provided -on the exterior of each of the fingels between the two' ends of said fingers.

The wire, l2,to be connected to the socketmember, 1, is passed through the central passage,.5, ofthe bushingand projected into the chamber, 4,'v and a tapered thimble or shell, "1'3, is then insert-ed 'overthe end of thc'wire,

and the latter is then secured in sajid thimble,

preferably by means of solder, 14, which'is poured into thc thimble. Bv this means the wire is secured in the thimble or shelland can not. be drawn back through the passage, 5. The plug-member, 2, of the connector is valso provided with a metal bushing, 15, having a longitudinal central chamber, 16, and

into .said chamber. 'lhis bushing is-pro vided at. its inner end with a pluralityv of L i lon yitudinal slots 18, formin 'a `iluralit of f g y ylc dunr or spring hngcrs, .19, wnch latter pro'eet intothe la cred recess, 4, of the soclietmwmlwr bus ling and will contact with the walls thereof. f 'lhe wire, 2U, to be connected to the plugnrember passes through the passa eway, 17,l

and is secured -bv solder in n. thimb e or shell,

2l, in tlul chamber, '16.

An insulating sleeve or covering, 22, surrounds the outer end of the liushing, I5, b'ut lea-ves the yielding lingers,i 19, uncovered. T his sleeve, like the sleeve, 8, of the socketmember, is provided with spaced-apart fin gers, 23, having beveled ends, 24, and. cir- Af ter the wires have had their ends secured in the two members the plugmember will then lie-inserted in the socket-member and the. two pushedl together -un'til'the fingers of one will fit between the fingers of the other '100.

and the beveled ends of the fingers onone member will project beyond-the Inner en ds of the fingers of the other member, thus iin-- suringa perfect covering for the two mem bers, as can beseen in Fig. 3. When the two gerswill aline and. form a continuous groove 75. a passageway, 17, at the outer lend leading io 7' 'members have thus been interlocked the cir- Q currferential grooves on the two sets of finwound around the interlocked fingers and in the ooveland serves to prevent the two mem ers from being se or,otherwise. It'wlll t ius be seen thatthe connection of the two wires is mede without em loying screws or devices of any character" which may work loose by vibration.

In the device shown in Fig. 4 the modiiication consists only in the manner of securing the wires in the bushings. Inthis device l end recesses, 27, are provided in the bushings, 28, and the wires are secured ln said recesses by pouring solder, around the wire.

Having thus described my invention what 2S), ltherein and I claim as newand desire to secure by Letters Patent is,

1. An-electric wire connector having a socket-member and a plug-member; an 1nsulating covering around each of seid members and the adjoining ends of said coverings havingintermeshing lingers and means for en agmg the 'lingers on the two coverings to hod the members together.

2. An electric wire connector having a socket-member and a plug-member; wires attached to said members; en insulating covcoverings having iingcrs and euch linger being provided wlthan exterior groove winch latter when the two members are joined, will register and form a continuous circumferential groove around the two members, and

means extending, around the grooves of all arated by vibration.

of said fingers to'hold the coverings and members together. -f f 3. .-Xrrfalctric wire connector having a socket-member provided at one end with lingers; n'wire connected to said socket-meni- 'kber a {dug-member having a yielding plug to enter the. socket-member and also having iingers to mtermesh with the lingers of the socket-member; n wire connected to the plug-member, and means engaging the lin# gers of 'both members to lock the two together.

"In'testnnony whereof l-allix my signature vin presence of two witnesses.
