Definitions

  • This invention relates to a clamp for suspending the overhead section wire for electric railways.
  • the object of the invention is, to make the r, overhead wire clamp of a construction which is as simple as possible, and can be easily and quickly manipulated, while having a very firm holding capacity and maximum adaptability to the curvature of the wire in bends.
  • the overhead wire clamp comprises substantially two clamping jaws hooked the one on the others without hinge pins, one of these jaws being rigid whereas the other is oscillatable and this rigid clamping jaw carrying a suspension boss and a screw threaded element mounted thereon which when being tightened swings the oscillatable clamping jaw into the clamping position.
  • FIG. 1 shows an overhead wire clamp in side elevation with the oscillatable clamping jaw bro- ,ken away on the right
  • Fig. 2 is a side elevation of Fig. 1,
  • Fig. 3 is a section through the oscillatable jaw taken on line 3-3 of Fig. 1.
  • Fig. 4 is a section through the open clamp taken on line 4-4 of Fig. 1,
  • Fig. 5 shows in a similar view to Fig. 1 a clamp of modified construction.
  • Fig. 6 is a top plan view of Fig. 5.
  • Fig. '7 is an end view of Fig. 5 with the oscillatable clamp removed.
  • Fig. 8 shows a part end view of Fig. 5, the
  • Fig. 9 is a section on line 9-9 of Fig. 5.
  • the clamping jaw l has on its inner side upwardly directed hookshaped projections 5 situated above the engaging edge 2 of the clamping jaw I.
  • the clamping jaw i as shown in Fig. 1 has three and as shown in Fig. 5 two internal hook-shaped projections 5.
  • the oscillatable jaw 6 has on its inner side downwardly directed hookshaped projections 9 by means of which the oscillating clamping jaw can be hingedly engaged in the projections 5 of the rigid jaw I.
  • the oscillatable jaw 6 also has at its mouth end a gripping edge 1 which when the clamp is tightened causes .5 the correspondingly sectioned overhead wire ll to be firmly gripped by the clamping jaws, see Figs. 2 and 9.
  • the rigid jaw i has a boss 3 which extends over the oscillatable jaw 5.
  • the oscillatable clamping jaw 6 is moved from its open position shown in Fig. 8 into the clamping position shown in Fig. 9 by a screw nut l0 mounted on an external screw thread on boss 3 and acts on a counter pressure surface 8 of the oscillatable clamping jaw 6.
  • a suspension bolt !2 loosely extending through the hub 3 and provided with a flange I3 is employed for suspending the clamp, the clamp remaining pivotable about this bolt even after the tightening of the nut.
  • side of the rigid jaw I rib-shaped lateral abutments 4 are provided which prevent mutual axial displacement of the jaws l and 5.
  • these abutments 4 are arranged on both sides of the middle hook projections 5, whereas in the modification shown in Figs. 5 to 9 they are provided on the inner side of the two projections 5.
  • the clamp can be bent into the necessary curved shape, to correspond with the curvature of the wire at the place of erection, provided the clamp is made of a suitable workable material.
  • Clamp for the suspension of profiled overhead wires for electric railways comprising in combination a rigid jaw, a wire guide at the lower end of said rigid jaw, upwardly extending hookshaped projections arranged one behind the other in the longitudinal clamping axis on the inner side of said rigid jaw, leaving intervening clear portions to permit subsequent bending of said wire in curves, a movable jaw, an oppositely directed wire guide at the lower end of said movable jaw, downwardly extending hook-shaped projections corresponding to the downwardly extending projections of said rigid jaw and forming therewith a hinge joint, a boss at the upper On the inner i:
