Definitions

  • An adjustable wire stripper comprises a pair of stripperblades attached to associated jaw members pivotably coupled to one another, the extent of closure of the jaw members being controlled by the cooperable engagement between a cam means coupled to one of the jaw members and a cam engaging means coupled to the other of said jaw members, the cam means, in one embodiment, being slidably movable lengthwise of its associated jaw memberin discrete steps to selectively position given portions of a cam means surface in confronting relationship with the cam engaging means on the other jaw member so that upon closure of the jaw members the cam engaging means is caused to abut a predetermined portion of the cam means surface.
  • Discrete positioning of the cam means is accomplished by the employment of a detent arrangement including, in one embodiment, a series of aligned depressions in the cam means engagable with a protrusion on its associated jaw member, the cam means being biased towards the protrusion for releasable retention in any one given position.
  • the cam means is fixedly coupled to its associ' ated jaw member while the cam engaging means is slidably movable along the length of its associated jaw member.
  • the stripper blades may be disposed on an offset portion of the jaw members to provide a more comfortable stripping motion.
  • lndicia provided on one of the jaw members serves as a strip length indicator adjacent the stripper blades.
  • a pair of cooperating cutting edges may be provided for severing a given length of the conductor from the remainder thereof.
  • the stripper blade closure is regulated by the manipulation of a disk-like cam member eccentrically rotatable about a pivot on one of the jaw members and engagable with a stop means on the other of said jaw members.
  • These devices although embodying relatively simple mechanisms, require the use of an external tool such as a screw driver or the like to lock the cam member in a desired position.
  • accurate adjustment is often not only difficult but also generally time consuming and cumbersome.
  • a further difficulty with this arrangement is the tendency of the eccentrically mounted cam member to be displaced out of adjustment as it is brought into abutting contact with the engaging means on the opposite handle of the strip per.
  • 2,863,158 differs from the aforesaid devices in that a sliding member is employed for controlling the extent of a jaw closure.
  • two separate manipulations are required to establish a required setting both manipulations requiring manipulative acumen to establish an accurate adjustment of the stripper blades. Accordingly, re-establishment of a particular setting after a change has been made therein requires the user to repeat the above procedure in each case.
  • the cam means may be suitably slotted and the jaw member provided with a rib portion slidably engagable within the cam means slot.
  • Situated 7 within the cam means is an obliquely angled cam surand repetitive stripper blade settings.
  • Stripper blade adface which may be either planar or stepped for cooperative engagement with the cam means so that, upon movement of the cam means, selective portions of the cam surface are presented to the cam engaging means for controlling the closure of the jaw members.
  • Predetermined selective positioning of the cam means may be accomplished by the employment of a series of aligned notches or indentations extending lengthwise of the cam means and engagable with a protruding finger affixed to the jaw member.
  • the cam means is fixedly coupled to is associated jaw member and comprises an obliquely oriented surface disposed preferably within the confines of the jaw member and engagable with a slidably movable cam engaging means coupled to the other jaw member.
  • the cam means may be further provided with one or more window-like apertures for viewing indicia located on the leg portion upon which the cam means is slidable to indicate, for example, the conductor size for which the stripper blades are adjusted.
  • the ends of the jaw members containing the stripper blades may be disposed generally at right angles to the plane of the jaw members to facilitate more convenient removal of the slug of severed insulation from the conductor.
  • Additional features include a return spring for biasing the jaw members in an open position for more convenient manipulation thereof, and locking means comprising, in one embodiment, an undercut portion on the cam engaging means engagable with a shoulder within the cam means to maintain the jaw members in a closed position during nonuse. It is therefore an object of this invention to provide an improved adjustable wire stripper.

  • FIGS. 1 and 2 there is shown an adjustable wire stripper 20 constructed in accordance with the concepts of the invention.
  • the adjustable wire stripper 20 comprises a pivot pin 22 extending through aligned apertures (not shown) in a first jaw member 24 and a second jaw member 26, each of said jaw members 24, 26 having a first end 28, 30, respectively, and a second end 32, 34, respectively.
  • a portion of the first ends 28 and 30 of the jaw members 24, 26 are formed at right angles to the plane of the jaw members, as shown more clearly in FIG. 9, the right angle portions having thereon stripping means 36 and 38 (FIG.
  • the second jaw member 26 further comprises a leg portion 40 extending lengthwise of the jaw member 26 and generally parallel to the inner edge 42 thereof. Slidably disposed on the leg portion 40 is a cam means 44 which, as more clearly illustrated in FIGS. 2 and 4, comprises a leg receiving slot 46 through which the leg portion 40 extends.
  • Cam means 44 further comprises a cam surface 48 extending generally oblique to the longitudinal axis of the cam means 44, and a series of selectively spaced, aligned indentations 50 disposed slightly inwardly of one edge of the cam means 44.
  • the leg portion 40 may have provided thereon selective indicia 52 which, for example,
  • the obliquely angled cam surface 48 may comprise a series of steps 54 (FIG. 3) on a cam means 44' following a similar path for engagement with a cam engaging means 56 rigidly affixed to the first jaw member 24 and having a flattened end 58, and an undercut portion 60 located adjacent the lower edge thereof.
  • the undercut portion 60 is adapted to engage a post 62 adjacent the lower edge of the cam means 44 or 44' to provide locking means for the jaw members of the wire stripper in a manner shown, for example, in FIG. 5.
  • Engagement between the cam engaging means 56 and the step 62 is accomplished by moving the cam means 44' upwardly in a direction indicated by the arrow 64 in FIG. 5 until the undercut portion 60 of the cam engaging means 56 coacts with the post 62, as shown in FIG. 5.
  • To disengage the locking mechanism it is merely necessary to move the cam means 44' towards the second end 34 of the second jaw member 26 in a direction indicated by the arrow 66 in FIG. 5.
  • Rigidly affixed to the second jaw member 26 is a raised portion 68 extending outwardly from the inner edge of the second jaw member 26 so as to cooperatively engage selective ones of the recesses 50in the cam means 44 (See FIG. 2).
  • the cam means 44 may be conveniently and rapidly repetitively positioned in discrete predetermined steps along the leg portion 40 to permit engagement of selective portions of the cam surface 48 with the cam engaging means 56 to regulate and control the extent of movement-of the first jaw member 24 towards the second jaw member 26.
  • the cam engaging means 56 upon contact with the cam surface 48 of the cam means 44 is in general alignment with the raised portion 68 on the second jaw member 26 so that the raised portion 68 provides an anvil-like support for the cam means 44 or 44 preventing its displacement in either direction from a preselected position upon the application of the force generated thereagainst by the cam engaging means 56.
  • the force applied to the cam means 44 or 44' by the cam engaging means 56 upon closure of the first jaw member 24 thereagainst is substantially counteracted by an opposing force supplied by the raised portion 68 on the opposite side of the cam means 44 or 44 so that the cam means 44 or 44' is, in effect, substantially balanced in its preselected position on the leg member 40 thus relieving the leg member 40 of undue stress during operation of the stripper 20.
  • This feature is also applicable to the embodiment illustrated in FIG. 3. It should be further noted that the end 58 of the cam engaging means 56 is oriented to coincide with the inclined surface 48 of the cam means 44 to provide an extended area of contact therebetween. As shown in greater detail in FIG.
  • a cam means 45 is provided with biasing means such as a spring 70 which bears against the leg portion 40 to resiliently urge the cam means towards the right, as viewed in FIG. 6, and against the raised portion 68 to provide a detent action between the raised portion 68 and the indentations 50.
  • the spring 70 is coupled to the cam means 45 through formed ends 72 and 74 engaging the upper and lower ends of the cam means 45.
  • the cam means may also comprise viewing means such as the single window 76 shown in FIG. 6 or a double window as at 78 in FIG. 7, to permit viewing selected portions of the indicia 52 on the leg portion 40 therethrough.
  • FIG. 1 the embodiment illustrated in FIG.
  • the upper surface of the cam means 47 comprises indicia 80 and 82, the former indicating the letters STR as an abbreviation for word STRANDED, and the indicia applied to the upper surface latter spelling out the word SOLID, both terms referring to the type of conductor configuration from which the insulation is to be stripped. It has been generally found that, for a given conductor gauge the outside diameter of stranded wire of a particular gauge is slightly greater than the diameter ofa solid wire having the same gauge member. Consequently by employing the arrangement illustrated in FIG. 7, a particular setting of the cam means 47 will indicate the proper size stranded wire and the proper size solid wire for which the stripper blades are set.
  • a spring member 84 partly encircling the pivot means 22 intermediate the first and second jaw members 24 and 26 respectively.
  • Each of the jaw members is recessed on its inner surface to provide a pocket or nest for the spring member 84 while a small aperture, such as 86, (see FIG. 1) is provided in each of the jawmembers to receive the respective hooked ends of the spring member 84 thus providing biasing means for maintaining the jaw members 24 and 26 in an open position substantially as shown in FIG. 1 to avoid the necessity for manually opening the jaw members after each stripping operation.
  • the spring member 84 may be replaced by other suitable biasing means such as, for example, a hair pin spring (not shown) affixed to outside portions of each of the jaw members 24 to perform a similar function.
  • the spring member 84 may be omitted completely, if necessary or desirable, so that selective manipulation of the jaw members 24 and 26 is performed manually by the user.
  • the second jaw member 26 may be provided with gauging indicia 87 extending from the stripping means 38 towards the pivot means 22 along one face of the second jaw member 26.
  • the indicia 87 provides a rapid and convenient means for indicating the length of insulation to be stripped from an insulated conductor such as 88 interposed between the stripping means 36 and 38 of the stripper 20.
  • a pair of opposing beveled surfaces 90, 92 formed, respectively, in the first and second jaw members 24, 26 coact to provide a shear for cutting a conductor to a desired length either before or after stripping.
  • FIGS. 11 and 12 there is shown an alternative embodiment of the adjustment portion of an adjustable wire stripper in which a cam means 94 is provided with a rib 96 extending along one edge thereof, rib 96 being slidably disposed within a rib receiving slot 98 extending along the inner edge of a second jaw member 104).
  • the cam means 94 may thus be slidably displaced along the second jaw member 100 to a predetermined or preselected position which may be indicated by an indicator line, such as 102 alignable with a series of indicia such as 104- provided on the adjacent surface of the second jaw member 100.
