It should be noted that the jaw I3 is notched The other or inner ends of the arms I are joined as at I3’ to accommodate the rib formations 3’ by a straight cross portion I I! which by means of and 4' on the strap ends 3 and 4 respectively a staple member II is pivoted to a lever I2 at a whereby a close gripping contact of the jaw trans point approximately centrally of the ends of the versely of said ends is assured and the jaws are lever as shown in Figs. 2 and 6. . prevented from slipping out of place. Fig. 3 shows In addition to providing the outer jaws 2 on how the opposed jaws 2 lie on opposite sides of the their outer ends, the arms I slidably support a rib 3’ in a depression 5' formed by off-setting the sliding jaw I3 extending transversely between said end 3 relative to the strap 5. This makes the jaws arms and which as here shown is one square end 2 lie substantially ?ush with the outer face of the of a plate-like link or arm I4 pivoted at its other and reduced end as at I5 to the lever I 2 at a point 20 offset portion of the end 3 (see Figs. 3 and 4) and permits of withdrawing the jaws 2 by spreading between one end of the lever and the portion I0 them apart after the clip is installed, as shown in and nearer to said one end than to said portion Fig. 4. III. The sliding connection between the jaw I3 With the arms I substantially horizontally dis and the arms I is provided by means of two in tegral guide members It located at the ends of 25 posed as shown for example in Fig. 2, it is seen the arm portions I8 are downwardly inclined from the jaw I3 which forms part of the plate-like and angularly related to the convergent portions link I4 and slidably hooked onto said arms as best I’! from the inner ends of which latter the re shown in Figs. 3 and 6. The members I6 are maining portions I9 of said arms leading to the formed as curled tongues bent to hook around the upper, outer and under sides of the arms I. The 30 pivot or cross portion IQ are extended angularly plate-like character of the link I4 makes it possi ble to form said tongues at minimum cost. The jaw I3 is adapted to engage the outer face upward in the opposite manner to the portions I8. The link or arm I 4 is bent or bowed outwardly intermediate its ends as at 20 so that the link is somewhat angular. These constructions and ar of one of the apertured ends of the strap 5, For example, as shown in Fig. 2, if the jaws 2 are set 35 rangements, together with the locations of the against the outer face of the apertured end 3, then two pivots, make it possible to fully operate the tool with a lever movement of approximately 90 jaw I3 will engage the outer face of the other end 4 upon manipulating the lever I2 from position degrees of are as against approximately 180 de shown in Fig. 2 to position shown in Fig. 7, thereby grees of lever movement required in the tool clamping the ends 3 and 4 together as shown in 40 shown in my former application and this saves Figs. 4 and '7, in preparation for applying the time and effort and makes possible operation of screw or bolt 1'. The tool will remain in position the tool in con?ned spaces, Moreover, the vari shown in Fig. '7 due to its toggle action and past ous bends of the arms I and I4 provide for a center movement of the lever I2 thereby leaving straight line thrust of the jaws, the collapse of both hands of the operator free to install the nut the tool into smaller compass than in the tool shown in said pending application, and make pos or bolt. The arms I are adapted to be spread apart to sible the application of the tool in the various spread the jaws 2 apart whereby they may be positions shown in Figs. '7, 8, 9 and 10. readily moved into position to engage one of the An important feature of this invention is that ends 3 and A of the strap 5, after which the arms 50 of having the jaws 2 and I3 substantially coplanar I and jaws 2 are moved toward one another to instead of the jaws 2 being spaced well below the engage said one of said ends, for example as shown plane of jaw 13 as provided in the tool shown in in Fig. 3. However, where the clip installation, said application. The straight portions E8 of the the width of the ends of the clip, the construction arms on which the jaw I3 rests when engaged of the support for the clip and adjacent structures 55 with one of the ends 3 and 4 make this possible, permit, the jaws 2 and I3 may be positioned to it being noted that in my former tool the portions engage the ends 3 and 4 of the clip without spread of the arms corresponding to portions I8 hereof ing the arms l and jaws 2 apart, it being only were arcuate. necessary to have the jaw I3 moved rearwardly By having the jaws 2 and I3 coplanar or sub along the arms I from jaws 2 sufficiently to bring 60 stantially so, it is seen they will more e?ectively the jaws downward over the ends 3 and 4 in grip and hold the ends 3 and 4 of the strap and opposition to the outer faces of said ends. pull them together so as to insure alignment of To provide for the spreading apart of the jaws the apertures therein. Moreover, this arrange 2, the arms I at points intermediate their ends ment of the jaws 2 and I3 makes it possible to have oblique and inwardly convergent portions I‘! apply the tool in the various ways shown in Figs. which when the guide members I6 and jaw I3 are 7 to 10 inclusive. moved thereon toward the inner or pivoted ends Fig. '7 shows the jaws 2 and I3 engaging the of the arms I, will allow the arms 5 to spring ends 3 and ll respectively with the tool nearly apart, said arms being tensioned as to move apart horizontal and the lever I2 uppermost. Fig. 8 as the jaw is moved in the manner above noted. shows the tool reversed and the lever lowermost. When the arms I are spread apart as shown in Fig. 9 shows the tool applied to bring jaws 2 Figs. 1 and 5, the Straight portions I8 of said arms against end 3 and jaw I3 against end 3. Fig. 10 extending between the jaws 2 and the convergent shows the tool in the reversed position of Fig. 8, portions I ‘I will extend divergently from said por tions I1. Therefore when the jaw I3 is moved 75 and engaging the clip as shown in Fig. 7, but 2,409,784 5 6 the tool extends upwardly and obliquely outward clip therethrough when the tool is positioned in front of said ends when clamping the clip on the as shown in Fig. 10. v To provide for ready access to the apertured ends 3 and 4 of the clip when the tool is set to hold said ends together, particularly as shown in Fig. 10, a large square opening 2| is provided duit-embracing and supporting clip having a pair of opposed ends adapted to be forced to in the arm or link Hi. As shown in Fig. 10, the opening 2| fully exposes the ends 3 and 4 per mitting of an easy insertion or removal of the gether to clamp the clip on a conduit and position said ends for application thereto of means for securing them together, a pair of opposed arms conduit. ‘ 2.
