BACKGROUND OF THE INVENTION In the field of conduit, tubular or pipe couplings a superior tubular connecting device was developed and is described in the Demler US. Pat. No. 3,674,292, the disclosure of which is incorporated herein by reference. The connecting device includes among other elements, a symetrical plastic body having a centrally positioned annular groove, and two ferrule members each having a laterally projecting flange at one end. The two ferrule members are drawn onto the body from either end by a hand tool having semi-circular jaw members. The nature of the tool is that it grips the groove with one jaw member and the flange with the other and, moving one jaw member toward the other, advances the ferrule member'onto an end of the body. The process is repeated for the second ferrule member.
Subsequent to the development of the hand tool it was discovered that the force being transmitted by the jaw members was being unevenly distributed on the I plastic body because the semi-circular jaw members were engaging the body for about 180. The uneven application of force sometimes resulted in body cracking 'or breaking.
Accordingly the present invention provides a hand tool for use in assembling tubular connecting devices wherein the two opposing jaws each consist of a U- shaped rigid base member and, continuing up from either end of the base member, a pair of opposing inserts,
each having a curved inner surface and pivotally at- FIG. 1 is a partial perspective view of the prior art;

DESCRIPTION OF THE PREFERRED EMBODIMENT FIG. 1 shows the head end of a prior art hand too]. At the end of handles 10 and 12 are identical jaw members l4 and 16. Each jaw member includes as an integral part thereof a pair of depending, slot-defining plates 18 which provide a method of attaching the jaw from FIGS. 1 and 2, the differences between the prior art tool and the present invention lie in the jaw members of FIG. 2 which will now be described with reference to FIGS. 2, 3 and'S.
Jaw member 24, which is attached to stationary handle 26, is identical in all respects to opposing jaw member 28 which is attached to moving handle 30. Each jaw member has, asan integral part thereof a pair of slotdefining plates 32. With an end of handles 26-30 being received in the respective slot, the jaw members are attached thereto by welding.
On top of plates 32 is the base portion 34 of each jaw member. Base portion 34 includes two lateral, rear supports 36 separated one from the other by a longitudinally-extending, semi-circular channel 38, and a U- shaped front plate 40 which extends across the front of base portion 34. The rear supports 36 are separated from plate 40 by recesses 42, one on either side.
A longitudinal hole 44 extend thru each rear support 36 and each leg 46 on plate 40.
lntersecting channel 38 is a U-shaped inwardly projecting rib 48 whose legs terminate about half-way up relative to supports 36 and plate 40.
Although the elements of the jaw member described above can be made from separate pieces and then joined together, the preferred method of forming is by milling so that each described element is integral with the whole.
Two generally ear-shaped inserts 50 are pivotally mounted in opposing relation in each jaw member, one in each recess 42, mounting may be by means of a pin 52 extending thru holes 44 and an aligned hole 53 in the inserts.
From the peak 54 of each insert the inside edge; i.e., the edge facing the opposite insert when they are mounted in a jaw member, angles downwardly to a lobe 56. Below the lobe, the edge is curved at the same radius as is rib 48 so that that surface and the shoulder surface 57 provides a smooth, continuous curved surface. The curved portion is designated by refernece numeral 58.
At the lower end of curved surface 58, the edge bends back to provide a generally flat surface which mates with the corresponding flat surface on top of each leg of the aforementioned rib 48. From that surface the edge presents a convex surface 60 curving members to the handles. The preferred method of such attachment is by welding.
The remaining portion of each jaw member includes a channel 20 terminated at its face by a U-shaped shoulder 22. a
FIG. 2 shows the head end of the hand tool embodying features of the present invention. As is apparent about hole 53 to a vertical surface 62 the bottom of which terminates the inside edge of the insert. As is apparent from FIG. 5, the convex surface provides a bearing surface between the insert and the vertical outside surface 64 of rib 48.
The sides 66 of each insert are relieved around hole 53 to accommodate a torsion spring 68. The spring, seen in FIG. 5, is. wrapped around pin 52 with its legs bearing against surfaces 62 and 64 thereby biasing the lower part (below hole 53) of the insert outwardly and the upper part (above hole 53) inwardly toward the opposing insert.
FIG. 4 illustrates the entire hand tool, hereinafter designated by the reference numeral 70. In addition to stationary handle .26 and moving handle 30, the latter being pivotally connected to the former by pin 71 extending through spur 73, the tool includes an actuating lever 72 which is pivotally mounted to moving handle 30, and double links 74 which are pivotally mounted to each side of stationary handle 26 and to lever 72. The arrangement of the handles and linkage is such that as lever 72 is pulled away from the handles, the jaw members 24-28 separate one from the other. As the lever is pushed in towards the handles, the jaw members approach each other.
OPERATION OF THE PREFERRED EMBODIMENT FIG. 7 illustrates a tubular connecting device for which the present invention was developed. The device, used to connect two flexible pipes 80 together, consist of an elongated body 82 having a centrally positioned annular groove 84 defined by annular body flanges 86 and tubular extensions 88 extending longitudinally outwardly from body flanges 86. In addition, there are two pipe insert members 90 (only one of which is shown) which are inserted into the open ends of the pipe being connected, and two ferrule members 92 which are drawn onto extensions 88 by hand tool 70. Each ferrule member has on one end a ferrule flange 94.
In assembling the connecting device, the ends of pipes 80, with insert members 90 therein, are pushed into passages 96 in body 82 as seen in FIG. 7. Ferrule members 92, with ferrule flanges 94 facing toward body groove 84, are pushed onto tubular extensions 88 by hand as far as possible. Hand tool 70 is now placed onto the partially assembled device (or vice versa) so that a body flange 86 is on the inside of one insert and the ferrule flange 94 on a ferrule member 92 is on the inside of the opposing insert. Referring now to FIG. 5, note that inserts 50 pivot outwardly to permit the passing therethru of the partially assembled device and as such comes to rest in channels 38, the inserts pivot back so that the surfaces of ribs 48 (surface 57) and inserts 50 (curved portion 58) almost completely surround the device (or more exactly, groove 84 and ferrule member 92) and that the outwardly facing faces of ribs 48 and inserts 50 bear against body flange 86 and ferrule flange 94. FIGS. 6 and 7 illustrate this positioning. Subsequent to the above positioning, lever 72 is moved towards handles 26-30 and jaws member 28 approaches jaw member 24, drawing ferrule member 92 onto tubular extension 88 upon ferrule flange 94 abutting the outside face of body flange 86, the connection as to that side of the connecting device is completed. The same process is performed on the opposite side to complete the connection.
While the embodiment illustrated in FIGS. 2-7 provide a curved surface 57 and curved portions 58 which together define an arc of about 315, an embodiment shown in FIG. 8 provides a curved surface 57 and curved portions 58 which together define an arc of about 360. This embodiment allows the tubular connecting device to be gripped completely around by the jaw members, of course, inserts 50 may be made with curved portions defining any desired arc.
