  • the invention is useable in any wrench having a pair of members moveable toward one another to effect gripping of a work piece.
  • the members in this sense would be the forward portion of the handle member 4 and the moveable clamping element 8.
  • One of these members, namely, the moveable clamping element 8 in the preferred embodiment has a forwardly extending arm portion generally designated by the numeral 40.
  • a length of chain generally designated by the numeral 42 is attached to the arm portion 40 preferably at the forward end thereof.
  • the chain 42 is adapted to be releasably peripherally engageable with a work piece such as that designated by the numeral 44.
  • the other of the moveable members in this instance would be the forward portion 6, as noted above.
  • the portion 6 is bifurcated and includes a pair of arms or tines 6(a) and 6(b) forming a claw or claw portion preferably having a chain engaging recess.
  • the recess in detail, is formed by aligned substantially semi-circular grooves 46 in the respective arms 6(a) and 6(b).
  • the chain 42 utilized in the preferred embodiment includes a successive series of links 43 and 50 joined by pivot pins 52 which project laterally of opposite sides of the chain 42.
  • Link chains of the type incorporating projecting pivot pins are well known, and accordingly further detailed discussion thereof appears unnecessary.
  • the first pivot pin 52 (a) of the chain 42 is used in accordance herewith to pivotally connect the forward end 46(0) of the arm 40 with the chain, or conversely to pivotally connect the chain with such forward end.
  • This construction feature is preferred, but of course, any pivot connection can replace pin 52(a), or a fixed connection can be used, although the same imposes certain limitations on operating characteristics.
  • the arm portion 49 of the moveable clamping element 8 has a longitudinally offset recess 6% formed therein intermediate the ends thereof and positioned to receive the chain 42 when the chain is looped under the claw portion formed at the forward end of the handle member 4. Accordingly, when the appropriate projecting pivot pin 52 is engaged within the recesses es of the respective arms 6(a) and 6(1)) of the claw portion, the unused length of the chain can be passed'in aligned relation to the gripping portion of the chain by and effectively through the arm portion 449. This operation may be described appropriately as permitting the chain to be maintained in a single plane, and without requiring any abrupt lateral diversion thereof.
  • the advantage of having the chain pass by and free of the clamping arrangement and actuating mechanism therefor is obvious-the unused chain does not get in the way.
  • the above described tool is adapted to accommodate work pieces of varying size by mere adjustment of the length of the portion of the chain used for gripping purposes.
  • the position of the rear or base end 12(1)) of the toggle link member 12 may be some necessity in adjusting the position of the rear or base end 12(1)) of the toggle link member 12 to permit proper locking of the toggle mechanism and the result proper gripping of the work piece by the used portion of the chain.
  • the required adjustment in this regard can readily be obtained by movement of the screw 14, as will be noted by the alternate positions of the abutment end 14(a) thereof shown in FIGURE 3.
  • the preferred embodiment possesses substantial advantage from the manufacturing standpoint in that the same incorporates a minimum number of components, and in that the relatively fixed handle member 4 thereof is formed as a single or one-piece body substantially entirely, or except for the adjustment screw 14 forming part thereof. Additionally, the moveable clamping element 8 can be easily formed as a single piece readily adapted for the described cooperation and disposition with other elements of the toggle mechanism which are already available.
  • the invention also contemplates certain modifications including the modified construction shown in FIGURES 5 through 7 and hereinafter referred to as the modified embodiment.
  • modified embodiment corresponds in most all respects to the preferred embodiment, and thus prime numerals have been used to designate component parts of the modified embodiment which are the same as components of the.

  • the claw portion 70(a) of the moveable clamping element 70 includes an arcuate recess 82 dimensioned to engage any roller to thereby releasably grip the chain 72 and tighten the same, in operation of the wrench, peripherally of a work piece.
  • the handle member 4' of the modified embodiment has a forward portion 84 forming a forwardly extending arm or arm portion.
  • the forward portion 84 is preferably a separate piece integrally attached to the main body of the handle member 4' as by yielding, and the handle member 4' is channelled to receive the base end 86(1)) of such In this inpiece, which is designated by the numeral 86.
  • the piece 86 forming the forward portion or arm portion as described above, has the longitudinally offset recess 9% therein, and this recess corresponds to the recess 60 incorporated in the preferred embodiment construction.
  • the attachment of the chain '72 to one of the clamping elements of the modified embodiment is the same as the attachment of the chain to one of such ele ments in the preferred embodiment.
  • the first pivot pin 78 is passed through a suitable aperture in the forward end 86(a) of the piece 86, and also through corresponding apertures in the first link 76.
  • the pivot pins 78 have enlarged heads to maintain the cooperative engagement of the chain with the piece 36 and the cooperative engagement between the chain links.
  • the operation of the modified embodiment is essentially the same as the operation of the preferred embodiment.
  • the recess 82 of the claw portion (70a) releasably engages a roller of the chain 72 thereby drawing the chain tight about a work piece between the attachment of the chain with the forward portion of the handle member 4jand the claw portion itself.
  • the operation, during closing of the tool is such that the forward portion 6 of the relatively fixed handle member 4 is effectively moved inwardly by virtue of the arm portioin 40 moving toward the same with forces transmitted to the moveable clamping element 8 by the toggle actuating mechanism.
  • the arrangement of parts andoperation of the modified embodiment is the reverse of the arrangement of the clamping parts and operation of the preferred embodiment.
  • the moveable clamping element 70 of the modified embodiment is dimensioned to be received in the channel of the handle member 4, as well as in the bifurcated forward end portion 19(a) of the handle member 10'.
