`26 Claims. (Cl. 173-263) This invention relates to connecters.

It is an object of this invention to provide forelectrical conductors, a connecter which may be manipulated with one hand when connecting two or more conductors.

In comparing a. connecter embodying this invention with those of the prior art, it will be observed that the parts are so arranged to co-operate with each other and with the electrical con- I ductors to be connected, that the operator may,

with one hand, place the connecter upon an electrical conductor and with the same hand operate the clamping elements, his other hand being free for other uses; whereas, the prior art connectors comprise elements whichnecessitate the use of both hands of the operator in applying the connecters.

A connecter embodying this invention generically comprises but three elements related to each 2 other in such manner, that they are always secured together regardless of Whether or not they are in clamping relation to each other. It will be noted in the subsequent description that this device when applied to an electrical conductor is virtually supported by the conductor and engaged thereaboutin such manner as to utilize the conductor as an element supporting the connecter and serving as one of the means of preventing rotation of the connecter when clamping the same.

Obviously, this will permit the operator to use one of his hands for other purposes.v

It is another object of this invention to provide a connecter which, when supported by an electrical conductor, will have its parts so -related at the beginning of the clamping operations, as

to prevent the connecter from being accidentallyl removed from the supporting conductor when the severalparts are being manipulated to clamping v vide a connecter of the type-noted which willl maintain proper alignment'of the several elements thereof, irrespective of the fact whether they may be assembled or disassembled invclamping relation.

Another object is to provide -a connecter of the type noted in which the'clamping pressure is disposed at all times in a plane substantially parallel to the axis of the clamping nut, thereby placing the threads in direct line of pressure.

Another object is to provide a connecter comprising simple elements necessitating a -minimum number of operations in the manufacture and assembly ofthe several parts. This object may be accomplished by using standard material, such as, tubing, rods, and sheet metal. 5

Figure 9 is a view in perspective of a portion. of the connecter. Fig. 10 is a view inside elevation of a modified form of the device shown in Fig. 6. 30 I 'Throughout the several views, like parts arev identified by the same reference characters.

'I'he connecter, shown in Figures 1 and. 2, comprises a wire engaging member or bifurcated sleeve I, a retainer 2, and a. clamping nut 3. The 35 wire engaging member I comprises a tubular element threaded upon its exterior periphery, provided with a shoulder 4 upon its interior periphery, and a transverse slot 5 upon opposite sides ofthe wire engaging member. The retainer 2 40 of the connecter comprises a disc or plunger portion 6 substantially the diameter of the larger bore 1 of the Wire vengaging member I, a second disc or closure portion 8 substantially the diame ter of the smaller bore 9 of the wire engagingv 45 member I, and a retainer disc I0 secured to the -second disc portion 8, in'any suitable manner.

such as, rivet II. The retainer disc` I0 is of a diameter larger than the diameterl of the wire engaging member I upon its outer periphery. 50

Threadably mounted on the wire engaging member I is a clamping nut 3 which, as shown in Flg- A ure 1, forces the conductors I5 toward the bottom of the slots 5 in the wire engaging member I.

#Irwin be noted that the discs fand s cf me retainer are connected at one side by means of the rod I4, which, in Figures 1 and 2, is segmental in cross-section. From this it will be seen that the disc 6 is held in contact with the adjacent electrical conductor Il by reason oi' the iact that the retainer disc III is in engagement with I the electrical conductors, it is necessary only to rotate the clamping nut l in a direction forcing it toward the retainer disc III. A continued rotation thereof will remove the clampingnut from engagement with the wire engaging member I and position it in supported relation upon the retainer disc III and about the second disc or closure portion 8. When the several parts are in the relation noted, the wire engaging member I may be then lifted vertically-to withdraw the conductors I5 from the slots 5, until the lower margin of the wire engaging member I is disposed above the conductors and the disc portion i of the retainer is' engaged with the shoulders 4. In this position the connecter may be then moved sidewise to withdraw the conductors from between the disc portions i and 8 of the retainer and from beneath the wire engaging member I. Obviously, when the connecter is applied' to an electrical conductor, the clamping nut 3 ,should be disengaged from the wire engaging member I and supported by the retainer portion 2 in spaced relation to tlrewire engaging'element, to receive an electrical conductor between the disc portions O. and l of the retainer and beneath the wire 'engaging member I. I! the retainer portion 2 is positioned so that the electrical conductor is disposed angularly relative to the slots 5 in the wire engaging member I, the conductor may be engaged or brought into contact with the rod I4 of the retainer to hold the retainer in given relation thereto, and to permit the wire engaging memberltoberotatedsothatslotswillbe in registry with and directly above the conductor. When the parts are disposed as indicated, the disc portion' I oi' the retainer may be positioned upon the conductor and the wire engaging member I allowed to move downwardly with the conductor disposed in the slots l and until it is positioned upon the clamping nut 2 'I'he clamping nut 2 may then be rotated into threaded engagement with the wire engaging member I. further lrotation thereof drawing the wire engaging member I into clamping relation with the conductor, as illustrated.

In assembling the device shown in Figures 1 and 2, 'the-retainer portion 2 will be inserted vinto 'the larger bore 'I of the wire lengaging member Figures 1 and 2 illustrate a connecter in which the wire engaging member I may be manufactured from standard tubular or rod material. 'Ihe retainer portion I may be manufactured from standard rod material. 'I'he retainer disc may be made of standard sheet metal material.

In manufacturing the wire engaging member I from standard tubular material. it obviously manipulated in the same manner, as

' will be necessary to upset one end to provide theshoulder I, then to thread the outer periphery'of n the tube, and then to slot it transversely o! its axis. 'In manufacturing the retainer portion -2, it would be necessary to turn the tube so that`a portion will have the diameter oi the disc portion 6 and a portion will have the diameter of the disc portion 8.A In turning the retainer 2, a

rivet will be left at the central portion of the disc portion 8 to be receivedin the aperture II in the retainer disc I0. It is, oi' course, apparent that the retainer disc Ill may be stamped out o! standard sheet metal stock.

It is believed that'all of the elements of the device described, lend themselves admirably to die-casting operations, ifit is so desired to manufacture the connecter.

In Figure 3, the embodiment of this invention comprises. a wire engaging member I like that Y shown in Figures 1 and 2. The retainer, however, is constructed somewhat diiIerently from that illustrated in Figures 1 and v2, the elements,

- however, being arranged to function in substantially the same manner as that previously de scribed.

The retainer shown in Figure 3 comprises a cupped plunger -20 having an eccentrically disposed'aperture 2I receiving one end of 'the rod is riveted at eachend to hold these respective parts securely upon the rod 22. 'As shown, the

rod 22 is disposed eccentrically relative to the wire engaging member I so thatit will be positioned at one side of the slots 5 in the wire Aengaging member I, when the connecter is assembled upon an electrical conductor.

'I'he'plunger 20 and the closure 22 may be formed out of standard sheet'A metal stock in a vmanner well known to those skilled in the art. The retainer may be assembled in much' the same mannerfin which the retainer 2` is assembled, as shown in Figures l and 2. The rod 22 may be ilrst secured to the plunger 2li, after which the rod may be passed through the wire engaging member I -with the plunger 20 dis-l posed inthe larger bore 1. The closure 2l may bethen secured to the rod, as illustrated. In use, the connecter illustrated in Figure 3 will be that described in reference to Figures 1 and 2.

In Figure 4 the wire engaging member 2l comprises a bifurcated element similar to that illus- 'trated in Figures 1, 2,' and 3, but it is provided with a flange 29 at its conductor engaging end.

-It will be noted that thismodiiied form of the wire engaging member is closed at its wire engaging end, the closedend being provided with an aperture 20 disposed eccentrically relative to the wirel engaging member 2l and receiving a wire 2|. loosely positioned therein 'for movement longitudinally of its axis. The wire 2i is-held against retraction from the aperture by the" beaded end l2. 'Ihe wire terminates at one end in a loop 23 having a diameter greater than the diaineter oi the wire engagingmember 2l. This looped end serves-to retain the clamping nut 3 in position to beengaged with lthe wire engaging member 28. A

As shown, in Figure 4, the looped end 33 of the Wire 3| may be continued into a smaller loop 34 which will serve to position the clamping nut 33 substantially for registry with -the wire engaging member 28. 'I'he wire 3| is preferably reversely bowed intermediate its ends to provide an arm or plunger portionA 35.

When a conductor is to be engaged by the connecter shown in Figure 4, it willv be passed between the wire engagingl member 28 and the clamping nut 3 to register with the slots 5, in which position the arm 35 will rest upon the conductor. The wire engaging member 28 will then settle upon the clamping nut 3, thus entirely enclosing the conductor so that it will not accidentally be withdrawn from the slots 5. The nut 3 may then be threaded upon the Vwire engaging member 28 to draw the conductor into clamped relation to the bottom of the slots- 5.

The modified form just described will be assembled by threading the nut 5 upon thevwire engaging member 28 and then securing the wire 3| in position, as previously described.

Figure 5 illustrates a connecter in which the wire engaging element 40 is similar to that shown in Figures 1, 2, and 3, with the exception that the wire engaging end is provided with a retainer flange 4|.

a clamping nut 3. The retainer shown in Figure 5 comprises a single piece oi?` Wire bent substantially as shown to form a plunger portion comprising two loops 42 superimposed one above the other and each substantially the diameter of the larger bore -1 of the wire engaging member 40,

and to form a retainer end loop 43 and a closure loop 44. Theclosure loop is substantially the diameter of the smaller bore 9 of the wire engaging member 40. The retainer loop 43 is of a diameter larger than the diameter of the wire engaging member 40.' i

The device shown in Figure 5 is operated in the samemanner as the devices previously described. When the device is being applied to a conductor or conductors, the conductor will be, passed between the wire engaging member 40- and the nut 3 supported by the retainer loop 43. The retainer will then be supported by the conductor upon engagement of the lower plunger loop 42 with the conductor. The wire engaging `-conductor, the nut 3 will then be threaded upon the wire engaging member 40 until it forces the conductor into engagement with the bottom of the slots 5 in the wire engaging member 40.

The retainer, as shown in Figure 5, operates in a manner similar to the retainers previously described. The loops 42 hold the retainer into alignment with the wire engaging member 40 for longitudinal movement therein. f The retainer may be formed prior to its assembly on the wire engaging member v4|). been formed as illustrated, the loops 42 may be inserted through the slots 5 at the lower end of the wire engaging member 40, by disposingA the loops in planes extending longitudinally of the` slots and then, after insertion through the slots, turning the loops to the position illustrated relative to the wire engaging member 40. Obviously,

This wire engaging element is threaded on its exterior periphery to receive When the retainer has when the loops `42 are being turned into the have been properly positioned relative to the wire engaging member 40, theywill maintain the retainer properly aligned.

Attention is directed to the fact that in the modified forms shown in Figures 4 and 5, the wire engaging members are each provided with a flange 29 and 4| respectively. 'I'hese flanges serve to prevent removal of the clamping nuts from their respective wire engaging. members after the arrangements have beenassembled. Obviously, in assembling these modified forms, the nuts must be placed in position before the final assembling operations are completed. If desired, the modified forms, shown in Figures 1, 2, and 3, may be provided with ilanges upon the wire engaging members I similar to the flanges 29 and 40, shown in Figures 4 and 5. In such cases the clamping nuts 3 will first be placed upon their respective wire engaging members I before the retaining portions 2 and retaining discs I0 are secured together as shown.

Figures 6, '1, 8, and 9, illustrate a preferred form of the invention disclosed herein. Inl this form the nut retainer maintains its relationship to the wire. engaging member 50 so that there is slots 55 adapted to receive electrical conductors,

and a beveled end |1 for guiding the clamping nut 53 for engagement with the threads on the wire engaging member 50.

The wire engaging member 50 is provided with a longitudinally extending aperture 51 with one of its walls coinciding with one Iof the walls of each of the slots 55, and the other of its walls vbeing offset from the otherof the walls of the slots 55. 'I'his longitudinally extending opening is rectangular in horizontal cross section, as will be noted in Figure 8, and receives the plunger 5B of the retainer for movement reciprocally thereof. The aperture 5141s provided on one side with a channel 54 extending from one end of the member 50 to a point adjacent the other end of the member, to provide a shoulder 54A. Integral with the plunger portion 55 is a lug 56A extending into the slot 54 and engageable with the shoulder 54A, thereby limiting the movement of the plunger in one direction.

.'I'he nut retainer shown in Figures 6, 7, 8, and

9, comprises the plunger 58 arm 8|, and block 58, having arms 59 disposed on one side of the nut 53 and arms 60 disposed on the other side of the nut 53. The several elements of the retainer vare connected as a unit and the arms 59, together with the block portion 58, serve as a jaw 1|, co-

operating with the jaw portion or bottom 12 of the slots 55. The jaws 1| and 12 are preferably f each V-shaped as indicated at i 1 and l12 in Figure 10. l Thus, when electrical conductors are placed between the jaws, pressure exerted by the jaws upon thezconductors will be substantially of the conductors and'parallel to the axisl of the 'Ihis will prevent the convclamping nut 53.

ductors from slipping sidewise relative to each other and tothe jaws, and will dispose the clamping forces directly in line with the pitch of the threads. In other words, any tendency of the bifurcated ends of the clamping member to warp, or become distorted, will be substantially eliminated, if not entirely so. As a matter oi.' fact. when the conductors areI disposed as they are in this connecter, the block portion 58 will be disposed between the bifurcated ends and serve as an additional strengthening element preventing distortion of the bifurcated ends oi! the wire engaging member.

'I'he nut retainer shown separately in Figure 9 is' illustrated as it appears after the die-casting operation. When completed, as shown,the lug 55A is disposed in a plane projecting upwardly from the plunger portion 56 so that the plunger portion may be inserted through the bifurcated end of the wire engaging member 50 into the aperture 51. After the plunger 56 has been inserted, it may be passed through the aperture 51 l so that the lug 55A may be bent, as shown in Figure 6. When thus bent to extend into the slot 54, it'serves as the retaining element for the retainer preventing withdrawal thereof from the wire engaging member 50. The arms. Eil extend vertically from theblock portion 58, as shown in Figure 9, after the completion of the die-casting operations. When the plunger has been secured in position, as previously noted, the nut 53 may then be positioned adjacent the armsl 59 and the 44,3 will be dropped vertically to enclose the conducoperated by the hand tors within the slots 55 and for engagement with the nut 5i. Obviously, this connecter 'may be operated with one hand when it is placed in position, as just noted, and then the nut 53 may be that positioned the connecter, as noted.

' I'he rectangular shape of the aperture 51 and the plunger 56 insures that the retainer and the nuts I when the connecter is being initially assembled on a conductor. This feature is of considerable importance, because it assists the operator 4in the use of' one hand when assembling the connecter.
