Definitions

  • ABSTRACT The invention relates to a free cable winch.
  • Each pair 7 July 29, 197i) France "70217876 of jaws 11 14 is guided by two pairs of rollers 18 52 U s (:1 24/68 1) 226/164 254/134 3 R in-geliqways [5 ⁇ ] B65h the winch case to ensure rectilinear traction of the [58] Field 6 1 3656 ;11111112113126 i/i iils' 226/163 cable .W tant no fl xi 0f the cable between the two pairs of jaws.
  • the invention can be applied to powerful winches with consequent low wear of the cable.
  • the present invention relates to a freely portable cable winch controlled by two external levers, one for traction, and the other for release or unwinding of a load, which permit good response to the requisite conditions for the rational use of this type of apparatus, that is:
  • Each of the two clamps of the known freely portable cable winch is solidly connected to a pair of dragging rods, by articulation of the extremities of two pairs of short levers of the clamp under consideration, on two fixed axes positioned, at one extremity of the pair of corresponding rods.
  • the two pairs of rods have different lengths, and are articulated on the two opposite ends of a crank which oscillates on a central axis.
  • FIG. 4 is a sectional elevation taken on the line X-X in FIG. 1,
  • the jaws 12 of the clamps by their double role on the one part as receiving members of unitary very high pressure transmitted by the earns 13 are made in steel of high quality characteristics and, on the other hand, the entraining members for the cable demand on their part mechanically contradictory qualities.
  • a steel treated to produce great hardness for resisting the high pressure of the cams l3, and a soft steel or an autenitic steel with a gripping tendency for the easy control and nonslipping of the cable are formed in two parts, providing between them a transversal socket of a dovetail form, the which profile is obtained by forming the jaws in long lengths by a hot extrusion and subsequent cutting off, which is a very economical method of production.
  • the central parts of the two supports 24, are connected and spaced apart by a shaft 25 on which oscillates in the space between the supports, a lever 26 controlling exteriorally the cable release movement of the apparatus.
  • a lever 26 controlling exteriorally the cable release movement of the apparatus.
  • On the lever 26 are symmetrically arranged with respect to the axle 25, two axles 27 and 28, which are driving members for two pairs of links, that is links 29 connected to the pair of top levers 14a of the short levers 14, of the clamp A, and links 36 connected to the pair of rods 14a corresponding to the clamp B.
  • the opening for the passage of the lever 26 can be enclosed in a plane surface of a length at least twice that of the said opening.
  • the preferred method shown in FIG. 1, comprises the inclusion of the opening 1b 2b, in the top part of the case, situated above the axis of the median zone of oscillation of the shaft 25 of the lever 26.
  • the said top part of the casing has the form of an arc of a circle, constituted by two symmetrical pressed portions of the cheeks 1 and 2.
  • an opening 1b 2b formed in equal halves in the said cheeks l and 2, the which opening is adequate for the extreme displacements of the lever 26.
  • each of the supports 24 is furnished with an opening 24c, and between the said openings 24c, face-to-face with the inside faces of the supports 24 is transversely placed a traction axle fixed to the end of a rod 33, itself articulated at its other end on a transverse axis 34a, fixed on a handle 34.
  • the security locking of the handle 34 is constituted by a latching assembly 35 with automatic closing.
  • the assembly of operating mechanism above described is completed by arrangements for automatic application of clamping of the clamps of a known type, constituted for the clamp A by a compression spring 36 taking bearing on an angle iron 37, solid with the cheek 1, and exercising a continual pressure on the clamp A, through a bearing cap 38, made in sheet steel, bridging the pair of extensions 14a of the levers 14.
  • the arrangement is constituted by a fixed bearing member 39 serving also as a bracing member between the cheeks 1 and 2.
  • a compression spring 40 guided by a rod 41, exercises a continual bearing pressure on a bearing bar 42, solid with the bottom part of the jaw 11 of the clamp B.
  • the thickness of the sheet steel of the case is uniform, and is calculated on the resistance to traction and the deformation which would be presented by a very weak portion of the surface of the case directly concerned in the effort of traction, the said portion of surface of the case concerned being situated between the bearing collar of the retaining book of the apparatus and the carrier bearings of the central shaft of the crank. From this it results that the rest of the surface of the case not concerned by the local effort, is made with an excessive thickness of sheet steel, which causes a useless dead weight.
  • Two symmetrical shells 43 and 44 made in thick sheet steel pressed into a form necessary for boxing respectively in the cheeks l and 2 comprising on their lateral portions a bore hole permitting their common riveting on the said cheeks 1 and 2, having the bearings 6 and 7, of the axle 4c, of the crank 4.
  • the symmetrical parts in angle iron of the shells 43 and 44 each comprise a semi-circumferential covering jointly arranged under the bearing collar 17a of the towing hook 17. This arrangement permits the support in a rational fashion of the transmission of the traction effort exercised by the axis 4c of the crank on the carrier of the collar 17a, by the two shells 43 and 44 only.
  • each shell has formed on itself coincident with the end of an opening at the bottom of the case in each of the cheeks l and 2, a male semi hinge 43a for the shell 43, and 44a for the shell 44, the which semi hinges are not shown on the drawing but are placed on one side and the other of the female hinge 3a of the base cover shown in FIGS. 1 and 3.
  • the said cover 3 is maintained in closed .position by a bolt forming the hinge pin, a bolt at the extremity, and a central bolt, of which the locking is rendered particularly effective by its clamping on the stop 39, which constitutes a cross member between the cheeks 1 and 2.
  • the free cable winch according to the invention does not have any difference in its cycling function from the known cable winch.
  • a free movable winch wherein there are opposed clamps controlled by two external levers, one lever for traction, and the other for release or unwinding of the cable, each of the clamps having two cams for applying the cable-gripping pressure to the jaws of the clamp, a part of at least some of the cams projecting laterally outside the jaws and providing axles carrying guide rollers which engage in rectilinear longitudinal guideways formed in the case of the apparatus, thus providing rectilinear and coaxial movement of the jaws of the clamps.
  • each of the axles projecting laterally from the cams are cut out from the mass of material from which the cam is formed, and has a substantially circular cross-section, which is completely circumscribed by the cam profile.
  • a free cable winch as claimed in claim 1 in which I the clamps are operated from the oscillation of the traction lever through a crank and twopairs of parallel connecting rods, one pair for each clamp of the apparatus, there being an elongated opening formed in each of the connecting rods associated with the clamp furthest from the crank, the axles projecting from the cams passing through these openings.
  • each clamp has a substantially U-shaped main jaw which at least partially embraces the cable, and a movable jaw located within the legs of the U-shaped main the lower part of the movable jaw is made in soft steel.
  • a free cable winch as claimed in claim 6 in which the two parts of the movable jaw are connected by a dovetail joint.
