  • the one hand, or plier type generally contains integral dies for a given external connector configuration while the bolt cutter and hydraulic types generally have provision for interchangeable dies for any given external connector configuration.
  • Prior devices for the most part, have therefore been dependent on a multiplicity of die sizes for each individual conductor size.
  • the tools of the prior art which have provided a fourway crimp have not been usable for overhead work by linemen and they have not been adapted for midspan crimping operations on a continuous conductor.
  • the present invention provides a novel tool which eliminates all of the undesirable features enumerated above and provides many advantages hitherto unrealized.
  • Ano her object is to provide a self-centering, positive acting crimping tool which will give a completely symmetrical four-way crimp on a single connector sleeve covering a wide range of conductor diameters.
  • An additional object is to provide a four-way crimping tool which crimps to a pro-selected pressure rather than volume of metal.
  • a further object is to provide a mechanical four-way crimping tool in which the crimping dies or nibs are maintained in orientation with a common center at all times during the crimping action and in which the dies move towards said common center in a straight line.

  • a pair of roller guide means each rotatably mounted in said head, are in rolling contact with
  • a first spring means biases the first slide member away from said stationary die.
  • Second and third spring means bias the auxiliary slide members outwardly from the axial extension against the respective roller guide means and the auxiliary slide members are movable toward the axial extension by the roller guide means during crimping movement of the first slide member toward the stationary die, whereby all of the movable dies are closed with respect to the stationary die.
  • Means is provided for actuating the first slide member and release means is also provided for limiting the operation of the actuating means at a pre-selected crimping pressure of the dies.
  • the angular relation of the arm member relative to the axial extension is such that the movement of the die member on the extension relative to the stationary die is the same in a linear sense as the movement of the other two dies is relative to one another.

  • a crimping tool embodying the principles of the present invention is shown and designated generally by reference numeral 2%. It has a head .21, hydraulic pump means 2.2 and a pair of handles 23, 24.
  • the pump means and handles are standard parts and of conventional design.
  • Head 21 provides single rigid means for mounting dies and has an opening or mouth portion 25 at the forward end as (see also FIG. 6) which is suitably dimensioned to receive a workpiece or sleeve 27.
  • Head 21 is composed of a metal housing 23 comprised of top and bottom halves 2 9 and 3d contacting one another along inwardly disposed edges 31 and being held in place by screws 32.
  • the front or forward part 33 of the housing 28 is open, permitting access into the operating space of the mouth portion 25 for the movable male crimping dies 34, 35, 355.
  • stationary jaw member 37 integrally formed with the head 21 at the forwend end 26 thereof is stationary jaw member 37 carrying inwardly disopsed male nib or die 38.
  • a first opposed pair 34 and 33 of dies and a'second opopsed pair 35 and 36 of dies are arranged around the space 42 and automatically providerfor sidewise entry of acable or the like into space 42 between/die 38 ahd die 36.
  • the .dies 34, 35, 36 and 38 each have a nose portion for biting into a connector.
  • slide member 39 Slideably disposed within housing 28 is slide member 39 having forward axial extension 40 carrying die member 34 at the front end 41 thereof facing die 33, and die 34 is movable by slide member 39 rectilinearly toward die 38 on stationary jaw 37 across operating space 42 of mouth portion 25.
  • Slide member 39 has a pair of outwardly extending arms 43, 44 which are angularly disposed in a forward direction relative to axial extension 40.
  • auxiliary slide members 47, 48 Slideably disposed along the forward edges 45, 46 of respective arms 43, 44 are rectangular trapezoidal auxiliary slide members 47, 48 which have base edges slideable on roller bearing means 49 or the like. Respective nibs or dies 35, 36 are mounted on facing edges 50, 51 of said auxiliary slide members 47, 48 so that they are oriented in a line at right angles to the line passing through dies 34, 38 and all dies are thereby aligned with a common center defined by the intersection of said lines.
  • auxiliary slide members 47, 48 are disposed at an angle with respect to the axis of rectilinear movement of slide member 39 and are maintained in rolling contact with respective roller guide means 54, 55 which are rotatably mounted within housing 28 near the forward end 26 of the head 21.
  • the slide members 47, 48 are thus cammed simultaneously toward each other.
  • Respective spring means 56, 57 bias auxiliary slide members 47, 48 against roller guide means 54, 55.
  • Additional spring means 58, S9 interconnect the outer ends 6t), 61 of arms 43, 44 with the back or rearward end 62 of the head 21 and thereby bias slide member 39 rearwardly, i.e. to the right as viewed in FIG. 6.
  • the back end 63 of slide member 39 is afiixed to piston member 64- which rides in hydraulic cylinder 65 and head 21 clamps around cylinder 65, said head being rotatable around cylinder 65 for positioning or alignment.
  • Hydraulic cylinder member 65 has suitable means such as threaded portion 66 for interconnection with suitable hydraulic pump and supply means 22 (see also FIG. 8).
  • Hydraulic pump means 22 is comprised of pump body 67 to which is pivotally mounted on a lateral extension as thereof socket member 69 in which is rotatably connected pump handle 7% Socket member 69 has respective fore and aft pivot stop members 71 and 72 to limit the pivoting action thereof (see also FIGS. 7 and Pump piston 73 is linked at its outer end with socket member 69 and is reciprocally movable in body 67 by action of socket member 69 through pump handle 70 in the usual fashion. Pumping action of piston 73 draws hydraulic fluid from reservoir 74- through check valve means 75 and delivers the fluid through interconnected passages 76, 77 and 73 into cylinder member 65 of the head 21 to actuate piston 64.
  • a second handle member 79 is threadably mounted at one end in extension 84 ⁇ on cap 81 threadably afixed to body 67.
  • Handle 79 has a hollow portion 82 which carries Within it rearward guide portion 83 of piston member 84 which is slideable in reservoir 74.
  • Handle 79 is threadable into extension 8t? to bring its inner end 85 against flange portion 86 of piston 84- to urge the latter to the left as viewed in FIG. 6 whereby the hydraulic pressure in reservoir 74 is caused to increase as will be explained in greater detail hereinafter.
  • Pressure release valve means 87 is included in pump body 67 and is interconnected between passage 78 and reservoir 74 (see also FIG. 13); By adjustment of the tension of spring 88, the rel ase pressure needed at inlet 89 can be preselected to determine the maximum pressure in cylinder 65 at which hydraulic fluid will be released through inlet 89 and pass via outlets 90' and a passage 96A back into hydraulic reservoir 74.
  • the actual operation of the release valve means 87 is indicated by an audible click and a partial release of pressure on the jaw mechanism.
  • Pump handle 70 is rotatable about its longitudinal axis from a normal pump position shown in FIG. 9 (in the direction of arrow A) clockwise to bring stud 91 in line with release pin 92 of hydraulic pressure release valve means 93 in the pump body 67. With the stud 91 and release pin 92 aligned, pivoting movement of pump handle 70 downward as viewed in FIGS. 6, 7, 9 and 10 causes stud 91 to bear against release pin 92 moving the latter downwardly against ball check 94 whereupon hydraulic fluid is permitted to drain from cylinder 65 back through passage 95 into reservoir 74 when handle 79 is unscrewed to its outermost position, i.e. to the right as viewed in PEG. 6 so that piston 34 may move to the right and permit the reservoir 74 to receive additional hydraulic fluid.
  • stop means may be provided for limiting the threaded movement of handle 79 into and out of extension 80.
  • stop means may be provided in socket 69 for limiting the angular rotation of handle 79 therein between the normal pumping and release positions heretofore described.
  • Handle 79 is then turned clockwise, and thereby screwed into extension so that handle end 35 will bear against piston flange 86 and as a coarse adjustmcnt cause hydraulic fluid to be delivered through the pump mechanism 22 into cylinder 65 of the head 21 and move piston s4 therein to the left as viewed in FIG. 6.
  • Slide member 39 moves against the bias of springs 58 and 59 causing die member 34 to move toward stationary die 38 and by such action dies 35 and 36 likewise move toward one another when the forward movement of slide member 39 and the reaction of roller guide means 54, 55 against auxiliary slide members 47 and 48 moves the latter against their spring bias toward axial extension 40 on slide member 39.
  • the coarse adjustment provided by handle 79 is continued until the sleeve 96 is gripped at four positions spaced around the connector by the four nibs 34, 35, 36 and 38 (see FIG. 14). At this point with the pump handle 70 in its angular position as shown in FIG. 9 it is pumped to actuate piston 73 and continue to deliver hydraulic fluid from the reservoir 74 through check valves 75 into the cylinder 65.
  • Such pumping action causes the movable dies or nibs to crimp or deform the sleeve 96 radially inwardly in conjunction with stationary die 33 through the progressive stages shown in FIGS. 15, 16 and 17, until the sleeve is crimped into generally cruciform shape in transverse cross section as shown in FIGS. 4 and 5.
  • Such progressive radially folding in of the connector sleeve 96 in the manner shown provides the universal adaptability of the tool and connector for joining various diameters of condoctors by one connector.
  • Die 34 moves at twice the rate as dies 35 or 36 to compensate for the stationary die 38 not moving in order that there will be relative movement of the dies equally in all directions to a common center.
  • die 34 moves up one-eighth of an inch while dies 35 and 36 move in one-sixteenth of an inch and up one-sixteenth of an inch.
  • each die is kept substantially equidistant from its respective two adjacent dies throughout the simultaneous movement of the dies.
  • the jaw nibs are of a triangular shape, or pointed, havsubstantially twice the rate of movement of each of the dies of said second pair, said dies being movable from an open retracted position wherein they are relatively spaced for reception of a connector toward one another for crimping the connector with each die remaining equidistant from its respective two adjacent dies throughout the simultaneous movement thereof, and means responsive to increase in pressure of the dies on the connector to a predetermined value for automatically relieving the pressure to terminate the crimping operation independently of the extent of die movement.
