Definitions

  • the present invention is described as embodied in a hydraulically operated hand tool in which the head of the tool can be freely rotated with respect to the hydraulic cylinder and tool handles and with the die assemblies keyed to the head so that they remain in proper alignment with respect to each other and with the head, and the operator can work the tool handles from a convenient angle.
  • One aspect of this embodiment permits the tool to be used in making connections on the standing part of a wire where no ends are available over which to slide the tool head. This feature also saves time in making connections near the center of long loose wires, for the head of the tool may be snapped quickly around the wire rather than threading the wire through the tool head or disassembling the head and reassembling it around the wire.
  • An additional advantage of this embodiment is that the head of the tool can be unlatched and the dies quickly removed and replaced by a different size or type of die.
  • a single tool may be used for several different sizes of wire and for making difierent types of connections.
  • a'single tool together with a set of dies is relatively light in weight; so that a lineman can carry these up a pole or into a manhole and work on several difierently sized cables without exchanging his tool.
  • Another advantage of the described embodiment is that the die assemblies are maintained in precisely accurate alignment regardless of the way the operator may twist and turn the tool handles to obtain the most convenient operation during crimping.
  • Figure 1 is a perspective view of a hand-operated hydraulic crimping tool, generally-indicated at 10, embodying the present invention
  • Figure 2 is a perspective view of a crimped connection such as may be made by the tool 10;
  • Figure 3 is a partial axial sectional view of the head and of the hydraulic cylinder of the tool 10, taken along the line 3-3 in Figure 1, showing the die assemblies in fully closed crimping position;
  • Figure 4 is a partial view showing the head of the tool in unlatched position and the ease with which the impression die and nest die may be removed;
  • Figure 5 is a cross sectional view of the base portion of the head
  • Figure 6 is another view of the base portion of the head shown in Figure 5;
  • Figure 7 shows a portion of the die assembly which may be used in the tool 10
  • Figure 8 is a partial axial sectional view of the head base swivelly connected to the cylinder of a differently arranged tool.
  • Figure 9 is a cross sectional view of the swivel joint taken along the line 9-9 of Figure 8.
  • the embodiment of the tool 10 as illustrated is adapted to make connections of the type formed by telescoping a sleeve or ferrule portion 11 (Figure 2) of a connector 12 over the bared end (not seen) of a conductor 13, the insulation 14 being shown broken away to reveal the conductor 13.
  • the connector and conductor are placed within the head 15 of the tool 10 and the connection is made by crimping the walls of the sleeve against the conductor, for example, as more fully described in U. S. Patent No. 2,535,013 to Thomas C. Freedom, issued December 19, 1950.
  • this tool may be adapted for use with various size conductors and for making connections to the intermediate portions of existing electrical lines where an end of the line is not available.
  • the top of the head of the tool as explained hereinafter, in detail, can be unlatched and quickly snapped around any wire on which a connection is to be made.
  • T-tap and X-tap types of connections such as are described in the application of William R. Evans, Serial No. 299,201, filed July 16, 1952.
  • T-tap or X-tap connectors have a generally U-shape which can be hooked onto the existing wire and then slid onto a new line from the side and crimped closed to form a junction.
  • the tool 10 shown in Figures 1 through 7 comprises, generally, a body 16, the head 15, which is free to rotate with respect to the body, and a pair of handles 17 and 13.
  • the tool is hydraulically operated, that is, during crimping the movable handle 17 is manually pressed toward the fixed handle 18 with a series of pumping strokes, and a piston rod 19 forces a hydraulic fluid into the ram chamber 20 within the cylinder wall 21 (see Figure 3) and behind the rear of ram 22 to drive it toward the head 15'.
  • Figure 3 shows the ram 22 fully advanced toward the head 15 after completion of the crimping operation.
  • the details of the operation and construction of the movable handle 17 and the fixed handle 18 and of the hydraulic circuit of this tool may be similar to those de scribed in the application of Kenneth E.
  • the compression spring 24 which acts to-returnithe ram 22 to-its-initial posit-ion when a pressure release valve .(not shown) is manually unseated :by turning a release-knob 25 ,(see Figure 1') following a'crimping operation, fits within-the cylinder 21 between anannular recess-26-in theb'ase 28 of the head -15 and rpushes against a :shoulder iltl on the ram 22.
  • the shoulder 30 has a peripheral ,groove 32 holding-an --ring backed up by va-leather washer.
  • adie assembly In order to support and drive adie assembly, generallydndieated at-3'4, comprisinga dieholder-36 and'an impression die piece 38, the faceof-the ram 2211215 a sooket40 into which the d-ie holder 3'6 is-pivotallysecured bya shoulder screw 42.
  • the-stem44 may be provided with an additional retaining groove to adapt the impression die piece for use in other tools.
  • a channel 52 (see Figure 7) is cut across the end of the die holder into which snugly fits the rectangular base 53 ( Figure 4) -of the impression diepiece 38.
  • a smaller channel-54m right angles thereto co-operates with a relieved area- 56 in the base of the die 38 to provide clearance so that when'the-dies are to be changed, thedie 38 may be started with a screw driver blade or the like, ifnecessary.
  • the impression die piece 38 and its die holder 36 are locked together -s a unit and are free to rotate with respect to screw 4.. turning independently of but bearing upon the ram 22.
  • the'tool 1-0 is particularly adapted for use in the maintenanceand construction of electrical power distribution systems and for work oft-intermediate and large size wires where the performance requirements of the connections are high.
  • crimped connections such as those described .above, it is known that-the form of the-crimp and the accuracy with which it is'made-are extremely important .factors indetermining its performance.
  • the connections must be very accurately 'made andthis is done by maintaining the nest die and impression die piece inaccurate alignment atall times during the-crimping stroke.
  • a nest die 64 Mounted in the head :opposed to'the die piece 38 is a nest die 64 having a stem 66 held in a hole 68 in the top 70 of the head 15 by a spring-biased ball detent 72 which snaps into a retaining groove 74 in the stem 66. Additional grooves may be provided in the stem 66 to adapt the nest die64 .for use in other tools.
  • the nest die 64 is prevented'from twisting in the top 78 by its rectangular base 76 which snugly fits into a recess 77 in the underside of the top 70.
  • One edgeof the base 76 is rabbeted at 78 to provide clearance for a screw driver blade to be inserted between the die 64 and the top 70, in case the die should stick when it is to be changed.
  • the top 70 of the head is hinged at 79 (see Figure 4) on a pivot bolt 80 so that'it may'be swung open.
  • a latch 82 hinged on a pivot 83 and having a hook 84 which catches under a tab or lip 86 on the head base 28.
  • the latch 82 is biased toward closed position by a spring 88 which is held in a slot in the latch 82 and is compressed between a lip 90 on the top 70 and the bottom 92 of the spring slot.
  • a stop 94 prevents the latch from being swung too far open.
  • the top 70 is freely hinged on the'pivot 80, and hence when the head 15 is elevated above the handles, as for example when a lineman on a pole reaches up to hook the top around a line, it may swing down toward closed position. As seen in Figure 4, the top 70 is balanced on its hinge 79 so that when it is fully open and the tool 10 is held in a more or less vertical position with the head 15 above the body 16, the top will remain open. However, when the top begins to swing closed, its center of gravity passes over the pivot 80 and gravity then pulls it toward its closed position.
  • the hook 84 slides down the inclined outer face of the lip 86, and when it has cleared the extremity of the lip, the bias spring 88 pushes the latch 82 into its closed position with the hook 84 under the lip 86.
  • a latch stop 95 holds the latch in a position so that the hook 84 can engage this inclined surface of lip 36 as the top 70 is dropping toward closed position.
  • the lineman can reach up holding one ofthe handles with only one hand and latch the tool in crimping position on an overhead line.
  • This overhead latching can be performed with one sweeping motion, saving the time and effort which is required with other tools for the lineman to climb further up the pole, adjust his safety belt, and put the tool in place.
  • he In using the tool it), he first unlatches the top and holds the head of the tool downwardly so that the top swings open, or opens the top with his other hand, and then with an upward swing the tool is latched in place.
  • this tool 10 may be provided with a quick take-up piston which is operated from the end of the handle 18 (not shown).
  • the quick take-up piston is depressed, causing the dies to close until they take an initial grip on the connector, preventing the tool from being accidentally slid off from the end of the connector.
  • the lip 86 has a slightly downwardly curved overhanging portion and a clearance is provided between the stop portion 95 of the lip 86 and the portion of the top 70 near pivot 83 so that the top 70 can move down toward the head base 28 the extra amount necessary for the hook 84 to catch under the lip.
  • the hook 84 becomes positively engaged behind the overhanging portion of the lip.
  • Still another advantage of this embodiment is the ease with which the die pieces can be removed and changed for other size ranges of wire when the top 70 is in open position, as indicated in Figure 4.
  • the head base 28 has three hinge plates 96. 97, 98 which mate with a correspondingpair of plates 1% (see Figure 3) on the top 70 and the hinge bolt 80 passes through these five plates.
  • the latch 82 has a pair of hinge plates 1102 and 104 ( Figure-1) to provide rigidity and strength and is of the same width as the hinge 79, for it must carry approximately one half of the total crimping force, and ,it serves further to align the die surfaces during cirmping.
  • the inside of the lip 86 and the inside of the hinge 79 are milled out at 106 to provide clearance for the nest die 64 when the top 70 is latched into closed position.
  • the cylinder 21 In order to attach the head 15 to the body 16 and to allow it to swivel thereon the cylinder 21 is provided with a flange 110.
  • Figures 8 and 9 are shown another swivel connection and a different impression die assembly, for use in a tool similar to the tool 10 described above. Parts performing functions corresponding to those in tool 10 have in certain instances been given the same reference numeral as in the previous description followed by the sufiix A.
  • a ram 128 is formed with a recess 130 to receive the stem 132 of an impression die assembly, generally indicated at 134, comprising an impression die 136 and a dovetailed key 138 which is forcefitted into a keyway in the side of the die 136.
  • the die assembly 134 is free to rotate on the ram 128, being held only by the spring-biased detent 140.
  • the key 138 slides along the keyway 139 in the wall 58A of the head base 28A, so that the die assembly 134 is always properly aligned with respect to the head base 28A.
  • a flange 110A is provided on the end of the cylinder 21A.
  • the head base 28A has an annular hp 142 which fits over the flange 110A.
  • a groove 144 is provided on the inside of the lip 142 and a split retaining ring 146 is compressed and slid into the groove 144 where it expands and locks the head 15A firmly on the body 16A.
  • Figure 8 shows the ram 128 and the die assembly 134 in retracted position.
  • a plurality of small holes 148 are drilled through the lip 142 into the groove 144 so that the split ring 146 can be compressed and slid out of the groove 144 when the head of the tool is to be removed from the body.
  • the tool shown in Figures 8 and 9 is also well adapted for work in crimped or awkward places and the dies are held accurately aligned no matter at which angle the tool is held. Moreover, the tool is capable of delivering a high crimping force so that it may be used on the intermediate and larger size wires with convenience and accuracy.
