- 3,170,345 PLIERS ESPECIALLY FOR (IRE [PING Roger Poingt, Vincennes, France, assignor to the Societe dite: 'Etablissements Prone: an Anonymous Societe, Montreuil-sous-Bois, Seine, France v Filed Dec. 18, 1961, Ser. No. 160,117 Claims priority, application France,l)ec. 19, 1960,
6 Claims. (Cl; 81-15) Farticularly when crimping electrical cables, the jaws of the pliers are separated morethan is required for the crimping itself, because the object to becrimped must be placed between them. For this reason, the closing of the jawconsists of two steps: the first for bringing the jaws closer together, the second for the crimping itself. During the first step, the exertion is theoretically zero and practically very little. All of'the exertion is expended during the second step; In practice, the second step begins just before the startofthecrimping;
The maximum opening of the jaws of the pliers demands a great spread of its handle; and if there is to be a suificient mechanical advantage, the extremities of the handle are so far spread apart that, at the maximum jaw opening, the handle cannot be grasped in one hand-an obvious inconvenience. r c
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.
By way of exarnpleonly, in the accompanying drawing;
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
fixed jaw 1 and a movable jaw}. The fixed jaw l, which has a notch 1a for accepting the object to becrimped, is 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 lil 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. One
extremity 3b of the .trigger is heldby spring 14 and has a toothed portion 8d which cooperates with latch 16,
mounted on axle 5a carried. by arm 5 and held by spring 17. 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,
togetheraforcejaw 2-towards jaw 1. v
an inclined slope, pushes pin 13 until it falls intonotch r 6,176,345 Patented Feb. 23,1965
When pin 13 falls into notch 3a of trigger '8, the latter ice is locked to arm 9. The pliers has now taken the position shown in FIGURE 2,.so'that when arm 9 is moved towards arm 5, the additional closing of jaw 2 quickly crimps the object placed in notch 1a.
During these movements, latch 16 engages toothed portion 8d, preventing arms 5 and 9 from'opening. -In the position shown in FIGURE 3, the toothed portion So has been moved beyond latch 16, thereby permitting arms 5 and 9 to reopen. I
Because of the latch, the person employing the pliers Spring 18 is sufiiciently strong to prevent movement of arm 9 while trigger 8 is moved by the index finger, but not so strong that more than negligible exertion is rem quired during the operation of crimping.
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. Consequentl'y,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. i
