Definitions

  • a major object of thisinvention is toavoid this inconvenience 'byinterposing a means between one of the jaws of the pliers and the arm of the handle that controls I it.
  • the displacement of this interposed means, while said arm is unmoved, causes said jaw to close towardsthe other jaw until said means is locked to said arm, the subsequent closing of which causes said jaw further to close and to crimp.
  • FIGURE 1 shows the crimping; pliers of the invention
  • FIGURE 2 shows an intermediate position of the; pliers:
  • FIGURE 3 shows the plier'sclosed;
  • FIGURE 4 schematically illustrates an advantage of the invention.
  • the pliers of FIGURES l.to*3 comprise two jaws; a
  • the fixed jaw 1 and a movable jaw ⁇ are secured by two rivets 3 to a stationary arm 5.
  • the moveable jaw is rotatablymounted on rivet 4carried by stationary arm 5.
  • An intermediate'meansin the form of atrigger. 8 and a moveable. arm 9 are rotatably mounted on, arr-axle 7 carried by stationary arm 5'. ,Within said arm 9'slides a traveler 19, held by spring 11.
  • Two pins 12 and 13 carried by traveler l il slidein respective slots 9a and 9b of arm 9.
  • a stop 6 carried by arm 5 limits the a movable jaw; intermediate meansconnecting said mov v displacement of trigger 8, which has a notch 8a.
  • extremity 3b of the .trigger is heldby spring 14 and has a toothed portion 8d which cooperates with latch 16,
  • a link 15 is pivotally connected at itsone end to a 5 pin 80 of trigger. 8 and at its'other end to apin 2a of jaw 2. Whenf he jaws are open, link 15 is practically perpendicular to animaginary line drawn between axles-4 and 2a.
  • the spreading of arms 5 and 9 by spring 18 is V tion ot arro,w'F,-towards fixed arm 5. Edge 8 actingas 3a. During this movement arms 5 and 9 remain .staftionary; but trigger 8, pivoting on'its axle 7, andlink 15,
  • latch 16 engages toothed portion 8d, preventing arms 5 and 9 from'opening.
  • the toothed portion So has been moved beyond latch 16, thereby permitting arms 5 and 9 to reopen.
  • the present invention is not limited in application to the above described pliers. It can be used in any pliers in which jaw 2 is displaced in two steps: a first step, requiring'little or noeifort, during which the jaw is moved from an open position 2A to an intermediate position 2B; and a second step, demanding a definite efliort, duringwhich the jaw is moved from position 213 to a closed position 2C.
  • the positionstaken by arm 9 corresponding to 2A, 2B, and 2C of the jaw '2 would be, for a conventional pliers, positions 9A,.9B, 9C. Thanks to the means. of the u invention'interposed between arm 9 and jaw 2, arm 9 takes only a single 'position, the position 9B, whilejjaw 2 is moved from position 2A topositionZB.” Forthis reason, 7
  • the angle of maximum opening ofifthe armsof the pliers handle is not 9A, 7, 9C, as inconventional pliers, but only angle 9B, 7, 9C.
  • the pliers of the invention In addition to its use for crimping, theipresent invention, for example, can be employed for bending, clipping or cutting, or the clamping of objects.
  • a pliers comprising, in cornbinationfa stationary arm; a stationary jaw fixedly mounted on said stationary arm; a movable arm connected to said stationary arm;
  • a pliers comprising,
  • a pliers comprising, in combination, a stationary arm; a stationary jaw fixedly mounted on said stationary arm; a movable arm connected to said stationary arm; a movable jaw; intermediate means in form of a trigger and connecting said movable jaw to said movable arm and being movable relative to said movable arm from a rest position to a locking position for moving thereby said movable jaw from a wide open position to an intermediate position without moving said movable arm; locking means on said movable arm and cooperating with said intermediate means when the latter is moved to said locking position for locking said intermediate means in its locking position to said movable arm so that said movable jaw may be moved from said intermediate to a closed position by moving said movable arm after said intermediate means has been locked thereto; and releasable means cooperating with said intermediate means for preventing return movement of said intermediate means during the movement from said locking position to a position in which said movable jaw is in closed position.
  • a pliers comprising, in combination, a stationary arm; a stationary jaw fixedly mounted on said stationary arm; a movable arm connected to said stationary arm; a movable jaw; intermediate means connecting said movable jaw to said movable arm and being movable relative to said movable arm from a rest position to a locking position for moving thereby said movable jaw from a Wide open position to an intermediate position without moving said movable arm, said intermediate means being formed with a notch; and locking means on said movable arm and cooperating with said intermediate means for locking the same in its locking position to said movable arm so that said movable jaw may be moved from said intermediate to a closed position by moving said movable arm after said intermediate means has been locked thereto, said locking means including a member mounted on said movable arm for movement relative thereto, and a pin carried by said member laterally projecting therefrom and adapted to engage in said notch when said intermediate means is in said locking position.
  • a pliers comprising, in combination, a statonary arm; a stationary jaw fixedlymounted on said stationary arm; a movable arm; pivot means connecting said movable arm to said stationary arm; a movable jaw pivotally mounted on said stationary arm; intermediate means pivotally connected by said pivot means to said stationary arm; link means connecting said movable jaw to said intermediate means, said intermediate means being movable relative to said movable arm from a rest position to a locking position for moving thereby said movable jaw from a wide open position to an intermediate position without moving said movable arm, said intermediate means being formed with a cam face and at one end of said cam face with a notch; and locking means on said movable arm and cooperating with said intermediate means for locking the same in its locking position to said movable arm so that said movablejaw may be moved from said intermediate to a closed position by moving said movable arm after said intermediate means has been locked thereto, said locking means including a member mounted on said movable arm .for movement in longitudinal direction thereof
