APPARATUS FOR USE IN :SPLICING on AssEI r LIivsoAB Es.

To all whom it mag concern Be it known'that I; OAMILLE Po'r -imn, a citizen of the Republic of France, residing at Paris, France, have inventednewa'nd use 'ful Improvements in Apparatus for Use in Splicing or Assembling Cables, of which the following-1s a specification. H I

This invention 1s an improved apparatus especially adapted for use inv clamping the.

cable sockets on the overlapping portions, of a cable or cables to be spliced or formed with an eye at one end.

The invention consists in the construction,

combination and arrangement of devices hereinafter described and claimed.

In the accompanying drawings Figure 1 is a side elevation,partly in scction, of one form of apparatusconstructed and arrangedin accordance with my inven tion. 1 V r Fig.2 is a front end elevation of the same with the die operating nut removed.

Fig. 3. is a detail side elevation of the dies 8, 10, and associated parts.--

Fig. 1 is a vertical central sectional view,

of a modifiedform of apparatus constructed in accordance with my invention.

Fig. 5 is partly an elevation and partly a vertical transverse sectional view of the same. 7 i -1 F 1g. 6 is a detail elevation of a cablc formed with an eye and-spliced'by means of i a cable socket which has been clamped on the overlapping portions of the cable by my improved apparatus.

Fig. 7 is a similar view of the same on a plane at right angles to that of Fig. .6.

Referring first to the form of my invention shown in Figs. 1 and 2 of the drawings,

the frame is preferablymade of steel and comprlsesa base 2, a standard 1, a body 6,

and ana'rmP which extends upwardly from one end of the body and is formed on the front side, andat the upper end, with an overhanging head 3. A vertically arranged screw 4 operates in a threaded opening with whichthe head is provided and said screw has arms .5 at its upper end fornnnglevers which enable said screw to be readily man,-

Serial nafz'ass i'. 4 I I forming a die 15. The body 6 has an openi-ng therein which extends therethrough from front to rear and in the rear portion,

'of said opening is fitteda die block 7* of oblong rectangular forn1,-tl1e said die block belng provided on its upper side with a (he 8 which is exposed in the lower portion of the groove 15 as shown inlflig. '1. The said 1 V die block a so has a torwardly extending screw stem 7. -A movable diesleeve 9 is arranged for slidingmovement in the front portion of the opening in the body 6, toward and 11011111l16'd10 block 7" and has an open- 111g through which the screw stem 7 extends,'

the said die'sl eeve being freely slidable on; sald screw stem and in said opening. The

rear upper portion of the die sleeve open hangs the front upper portion of. the die block 7 as is clearlyindicated in dotted lines inFig. 1 and said die sleeve has a die 10 which is "opposed to the die' 8. 11 U-" shaped spring 12-l1as its bight portion sesleeve 9, the function of said spring being 7 to move the die sleeve 79 away from the die 8'. To cause the die sleeve 9 to be moved rearwardly and thus cause the diel10j to' when an eye is to be formed in one end of a cable the overlapping. cable portions B, C, are first passed through a cable socket A which is a metallic tube of initially substan 9O VVhen' cables are to be spliced together or tial ovalform incross section. Where air eye is to be formed-in the cable as shown in Figs. 6 and '7, a thnnble l) is also placed in the loop or eye 01' the cable and at one end of the socket A. Initially the dies 8, 10,'are apart, and 'fl1G- 111l?61 1116d13,t-B portion or the rablesoclret A s arranged between said dies and on the die 1-3. The die 14 is then moved downwardly by means of the screwd and caused to coact with the die 15 in closing the. end E of the'cable' socket around the overlapping portions B,;-C of the cable; The screw 13 is then turnedby its lever handle'13 to cause the sleeve 9 with its die 10. to move toward the relatively fixed die 8,said' dies'S, 1O engaging the intermediate portion ofthe. cable socket onopposite sides and flattening and widening the same as at G in Figs. 6 and '7, thus completing the rigid gripping and securing of the cable socket. The two screws are then slackened, to w1thdraw the dies, and release the cable socket,

' the latter being then removed from the apparatus, the securing of the said cable socket on the cable being complete, Q According to Figs. 4i and 5 the apparatus is formed by a part 16 having a central space 17 and a cylindricalhead 18 in Which is a screw 19 operated by an ordinary tommy passing through the head of the screw. the lower part a strong tenon 20 fits into a support 21 and a clamping screw serves to fix the whole togetherg In the body of the base plate 16 and horiaont-ally arranged are two holes 23, 2*l into which can be displaced the parts 25, 26 having vice-jaws 27 and 28 which assure the compression of the tubeA intended for the assemblage of the metallic cables when the latter are disposed in the recesses 29 and 30,

of theopposed' dies 81 and 82 and that are maintained in this position by adie 38 hav ng corresponding recesses 3e and The die isloosely mounted at the end of the screw 19 by atail piece 36 engaging an axial hole 37111 the screw. .lVhe'n the latter is operated the pressure is received by the die 83wl1ich rigidly maintains in position the cables to be assembled.

In order to allow of the necessary play or the parts of: the- vice 25 and 26, at the desired moment, the part 25 is PlOVlClGCl with a tail piece 38 screw threaded at 39, passing through the part 26 and receiving a nut l0 with a head a1 and hole a2 for the reception of atommy or operating lever not shown in the figure.

hen the nut 40 is actuated, the parts 25 and 26 approach each other with axial disr the base in a space 1 3 by a screw threaded bolt l6 forming an annular ring.

In order to allow of the operation of assemblage or splicing of the metalliccables, Figs. 6 and 7, the cables, previously provided with the oval'tube to form the cable socket A, are laid in the recesses or grooves compression or squeezing action on 29 and 30 of the opposed dies 31 and 32; the screw 191s operated which effects the the cables through the die 33 and the nut 4:0 is then actuated.

By thelatter operation the parts 25, 26

approach each other, the jaws 27 and 28 come into contact with the tube containing the cables to be assembled and under forcible action on the nut 40, the said jaws 27 and 28 squeeze the tube which forms the cable socket. V

The apparatus which is simple and of rigid construction allows of operating on metallic cables whatever their diameter and assures the assemblage, of metallic cables in such manner that the latter are proof against rupture and the cable socket described is not subjected to being torn off or to deformation.

The cable socket itself or the socket thread may also be used to efiect the connection of electric conducting wires, to ligature all threads in general whatever may be the metal employer.

hat I claim is: 1

1, In a machine for securing a cable socket on overlapping cable members, a pair of opposed dies arranged for relative move ment'toward and from each other and to grip and close the ends of the cable socket, and a second pair of dies arranged for relative movement toward and from each other to grip and press the intermediate portion of the cable socket between them and on the cable members, the plane of relative movement of the last named dies being at an angle to that of the first named dies and intersecting that of the first named dies.

2. In a machine for securing a cable socket on overlapping cable members, a pair of opposed dies arranged for relative movement toward and from each other and to grip and close the ends of the cable socket, and a second pair of dies arranged for relative movement toward and from each other to grip and press the intermediate portion of the cable socket between them andon the cable members, the plane of relative movement of the last named dies being at can angle to that of the first named dies and intersecting that of the first named dies, and a spring to normally move the last named dies apart.

In testimony whereof I afiix my signature in presence of two witnesses. a
