This invention relates-Ato a `hand operated metalworking tool and more particularly'zto a swaging toolv for applying a iitting .to a member such as an elongated member .andY hasbeen shown as adapted toapply a at'strand,'cable or rope.v H I Among-the objects'. of this invention are irnpr'ovements in hand operated metalk working toolsmore particularly for applying altting on.

a cable or the Vlike or for applying afconnector to adjacent ends ofcableslorffthe like and which is'ofsuch :light weight as to ber portable and which has provision for adjustments` so thatethe swaging or other metal working operation'may be performed in` several stages.U

The legs of the cable supporting bracket are provided `with slots 32 and-33 in-alinement with the slot I3 in the body portion. 6 and ofi'arwidth equal to the `diameterrof theA cable and the lower'ends of the slots lare provided with half round right angularly related extensions' 34 and 35 ofthe same diameter as the diameter of the cablefand in alignmentfwith the. groove I9 and in the vdie block yII, 'the'A lower edges of kthe ,extensions being alined :with vthe bottom wall of the slotl3 in thebodyto support the cable.

dieIZ to move the die 1I2 into the Topen. positiony in.Fig.1.* o The upper operating handle r8 extendsk into ya socket in a slidable pivoted cam head 4I)` in'which The head 40 is providedwth a^narrow portion 4I which operates between inwardly extendingr opposed

flanges

42 and 43 `on the upper edges of shoe plates 44 yand 45 secured to ythe body portion-by screws46 as indicated in some of the vfigures. This head is of the general form shown in the' gures and its depending portion 56 isprovided with a. wide bearing portion 5I carrying a pivot pin52 operating in slots 54 and 55. in the shoe plates 44 yand 45, This wide portion provides -zshoulders vcooperating with the`

opposed fianges

42 and 43 tolimit the opening movement, of the operating handle 8. The forward end ofthis wide portion is provided with a cylindrical face 60 bearing in a concave scat 6I inthe rear end of the movable die I2, and alining the groove 20 of the movable die I27with vthe groovefl9` of the stationary die II. t The rear end of the enlarged portion 5I is'provided with an arcuate eccentric carn face 62 cooperating with a backerfroller 63 supported by a leaf A'spring 64 secured to the body portion by. means ,of l'a bar plater 65 tenoned `in the shoe plates 44 and45.- The backer roller is retained in position by a bar plate 66 tenoned in the .shoe plates as shown.

y:The roller cooperates with a roller backer block 10 provided with rectangular guide lugs "II, 12, operating in horizontal slots in the shoe it may be adjusted in the slots in the shoe plates to control the forward limit of movement of the movable die during its forward movement. This adjustment screw is rotated by means of the lower handle 1 to which it is secured by a transversely extending pin '15. The front face of the roller backer is arcuate and substantially concentric with the pivot pin 52 so that the cam face on the rear ofthe head 5I operating on the roller will cam the head and move the die I 2v forwardly to swage and compress the end fitting on the cable.

In the use of the swaging tool, the lower hxiirL.` ".I

dle 'I is rotated to control the operated position.4 of the movable die in accordance with the said body portion, an opposed movable die supported in said body portion, a roller supported v. in said body portion, a cam between said roller vfg'rand said n'iovable` die, a handle for operating amount of reduction desired to be'eifectedfduring the lrstseries of swaging operations. The dies are then separated and the cable with the blank i Y tting on it is passed through the slots32 and 33 of the cable supporting bracket 3I into the

extensions

34 and 35 of these slots vand the blank tting is seated in the die face kI'I of thestatio'nary die II. These diesk are .closed and opened and the cable is rotated until thedies have op-` erated at the required number of different points circumferentially of the tting after which theY lower handle is turned clockwise as viewed from the right of Fig. 1 to advance the roller backer 'Il the head`5I of the upperhandlef and the movable die I2 afterwhich a second series of operations is performed as before and so forth and for the last series of operations the roller backer is advanced to cause the movable die to engage the stationary die at the limit of `its forward movement.

It is obvious that this invention is not limited to the shape of the faces of the dies and that these faces may be given yany desired Vshape de.

pending upon the original and/or desired ilnal cross sectional shape of the fitting or the shank of the fitting and that a'swaging tool built .in ac, cordance with this invention may be used to apply fittings not only to an end but alsoat. any point along the length of a cable or yanyoth'er elongated member and to connect anymember to or about another member regardless of the relative axial dimensions or lengths of the members and to change the cross sectional shapes of,

perform other operations on, articles of various kinds.l

While I have described a preferred formiof my.

invention, it is to `beunderstood that this .has been done for the purpose of disclosure only and that I reserve the right to make such changes as fall within the principle of the invention` dise1 provided with a handle, a fixed die Ysupported-in said cann'said roller being supported for rolling movement with said cam, a spring normally urgingsaid "roller into its home position, means on saidbody portion stopping the roller in its home position, and means also on said body portion` stoppingl said cam in its home position.
