  • This invention relates to clamping devices used for suspending conductors from insulators.
  • the principal Object of the invention is to provide a suspension clamp which may be manufactured very simply and cheaply and yet be capable of giving as efli-' cient service as those of more expensive design.
  • An important object of the invention is to provide a suspension clamp formed in a pcculiar manner toprovide van'adequ-ate-bearing seat to which'is clamped a conductor engaging keeper, said seat or ssaddle portion :16 being struck out from the sides of :the body portion, the entire device, aside from the keeper member, being capable of being formed from a single pieceof sheet metal stamped or cut and'pressedto possess the de- 2 sired configuration.
  • Yetvanother object of'the invention is to 1provide a suspension clamp embodying a eeper' or relatively movable clam-ping element anda U-bolt, the keeper memberzha'ving portions thereon coop'erating'with the bolt to prevent longitudinal displacement, said portions being inth'e "nature of lugs straddling thesides of the bolt and" these lugs being capable of engagement withthe side of the clamp when load'is applied whereby to increase the slip strength of the clamp and make it possible'to employ a U-bolt-of comparatively smallisize.
  • the clamp as comprising a 'relatively stationary member 1 andvarelatively section movable member :orkeeper 2.
  • Themember 1 is preferably of curved shape throughout andis substantially U-shaped in cross section in that it includes a channel-like bottom portion 3 and upstanding side portions 4 which are formed with-openings 5 for the reception o'fsuspension means such as ,a-hook or thelike located at the bottom of a string of insulators or other support.
  • the bottom wall or portion 3 of the member 1 is not only curved transversely throughout the -major portion of its length but is also longitudinally curved to provide flaring ends 6 which permit a certain'play in the conductor 7 without it coming in contactwith the edges of the ends it being well understood-that chafing or other wear at these points should be strictly avoided as being injurious to the conductor.
  • a "base, seat or saddle portion 8 which is preferably flat and "which is defined partly by' lateral projections -9 stamped or struck outfro'm the sidesA: whe'n'the-openings 5 are formed'therein.
  • this base or saddle portion by striking out a portion of the metal left when the openings 5 'are formed, thejmaterial of the sidesis pressed out adjacent the openings 5 as shown at 10, the material at these points merging into the lateralextensions 9.
  • the conductor lies upon the curved bottom portion, 3 and the flat central base or saddleportion 8 of the member l, and clamping is effected by means of -a preferably elongate'd' relatively movablemember or keeper 11 which is preferably concavo-convex in cross section with: its concave side engaging the conductor.
  • the device includes a U-bolt 12 which passes through suitable holes in the base or saddle portion 8 and which has" its-arms provided with nuts 13 engaging against the underside of the saddle portion.
  • the keeper is shown as provided at opposite sides with lugs 14 notched at'15 for the accommodation of the arms of the U-bolt.
  • the device may be made from a flat blank which is stamped or cut to give it the proper contour and to define the openings 5.
  • the material at these openings 5 is not all removed as sufficient is leftand pressed out to define the lateral extensions 9 which form the base or saddle portion through which the U-bolt extends when installation is made.
  • the blank is folded longitudinally and pressed by means of suitable dies to give it the longitudinal curvature and the proper shape in other respects. The bulgingof the material outwardly at the sides of the openings 5 to permit it to merge into the lateral extensions 9 will increase the strength and rigidity'of the clamp.
  • the device is of course installed and used in the same manner as any other clamp for the same purpose. WVhen heavy strain comes upon it it is possible that there will be a tendency for the sides to draw toward each other and if this should occur it is clear that they may engage against the opposite edges of the keeper member 11 and assist the clamping action theerof. If a conductor of sufficiently large diameter be clamped by the device, the lugs 14 may possibly engage against the inner faces of the sides 4. It will be noted that owing to the provision of the notched lugs at the side edges of the keeper there will be no possibility of longitudinal displacement of the keeper with respect to the relatively stationary portion of the device and the holding action will therefore at all times be assured.
  • a relatively stationary member of elongated shape substantially U-shaped in cross section and having a transversely and longitudinally curved bottom portion and spaced parallel upstanding side portions, said side portions being formed with opposite openings, the central portion of the bottom being formed with.
  • lateral extensions at the lower ends of said openings said lateral extensions being formed with holes
  • a keeper member located between the sides and cooperating with the bottom of the relatively stationary member to constitute clamping means
  • a U-bolt straddling said keeper member and having its arms passing through said holes and equipped with nuts.
  • an elongated relatively stationary member substantially U-shaped in cross section and including a longitudinally and transversely curved bottom portion and spaced parallel sides merging thereinto, said sides being formed with openings for the reception of a suspension element, a portion of the material left in forming said openings being struck out to define lateral extensions merging into said bottom and into the sides, said lateral extensions defining a central saddle portion, said saddle portion being formed with spaced holes, a keeper member located between said sides and formed at its opposite edges with notched lugs, and a U-bolt straddling said keeper member and passing through said holes with its ends equipped with nuts, said notches accommodating said bolt.
  • a relatively stationary'member of elongated. shape substantially U-shaped in cross section and having a transversely and longitudinally curved bottom portion and spaced parallel upstanding side portions, said side portions being formed with opposite openings, the central portion of the bottom being formed with lateral extensions at the lower ends of said openings, said lateral extensions being formed with holes, a keeper member located between the sides and cooperating with the bottom of the relatively stationary member to constitute a clamping means, and a U- bolt straddling said keeper member and having its arms passing through said holes and equipped with nuts, said keeper member having notched portions at its sides accommodating'said bolt.
  • a relatively stationary member including a curved bottom portion and spaced sides merging thereinto and provided centrally with elongatedopenings adapted to receive a suspension element, said relatively stationary member being provided at the bottom with lateral projections formed from the material struck out in the formation of said openings, said lateral extensions and the portion of the bottom therebetween constituting a central fiat saddle portion, the material at the sides of the openings being bulged outwardly and .merging into said lateral extensions, a keeper member cooperating with. said bottom, and bolt means engaging the keeper member and passing through said saddle portion for effecting a clamping relation.
  • openings folding the blank longitudinally to define spaced parallel side portions connected by a curved bight portion, and striking out a portion of the materials at the adjacent ends of said openings to define extensions projecting laterally beyond said sides to form a central relatively flat saddle portion.
  • a body substantially U-shaped in vertical cross section having its bottom adapted to support a conductor and having sides formed with openings, the body having lateral extensions at said openings, a keeper member located between the sides and cooperating with said bottom to constitute clamping means, and a bolt embracing the keeper member and said extensions.
  • an elongated body substantially U-shaped in vertical cross section and including a bottom portion adapted to support a conductor and further including spaced sides having openings, a lateral extension on the body opposite the opening in the side thereof, a keeper member located within the body and cooperating with the bottom thereof to constitute clamping means, and a bolt engaging the keeper member and passing through said extension.
  • an elongated body including a bottom portion and spaced sides having openings therein and formed with lateral extensions at the openings, a keeper member located between the sides and having laterally extending portions located within the openings, and bolt means embracing the keeper member and passing through said first named lateral extensions.
  • an elongated body including a bottom portion and spaced sides having openings therein and formed with lateral extensions at the openings, a keeper member located between the sides and having laterally extending portions located within the openings, and bolt means embracing the keeper member and passing through said first named lateral extensions, said last named lateral extensions being notched to accommodate the bolt.
  • an elongated body including a bottom portion and spaced sides formed with opposite openings, a keeper member enclosed within the body, and bolt means within the openings. embracing the keeper member and passing through the bottom portion of the body.
  • a body including a bottom portion and spaced upstanding sides having openings therein, a keeper member enclosed within the body and having projections received within the openings, and bolt means located within the open- In testimony whereof I afiix my signature.
