Definitions

  • the present invention relates to a deformable nut which'automatically locks itself when tightened and the bearing face of which automatically sets itself parallel with the face of the part to be clamped.
  • the nut accordingto the invention is characterised by the fact that it comprises an inner tapped part or barrel and an outer part or skirt which is arranged parallel with the barrel, said two parts beingconnected together by a web which is substantially perpendicularto the axis of the nut on the-opposite side to'the part on
  • the barrel is slit along one or a plurality of generatrices so as to make-the part resilient.
  • the web, substantially perpendicular to the axis of the nut, and optionally the upper parts of the barrel and of the skirt are slit, for the same purpose.
  • Fig. 1 shows the nut according to the invention in vertical section along the line I-I of Fig. 2, and not tightened on a bolt shown in outside elevation.
  • Fig. 2 shows a top plan view of the nut.
  • Fig. 3 is a section along the line III-III of Fig. 2.
  • Fig. 4 is a view similar to Fig. 1, the not locked on the bolt.
  • Fig. 5 is a similar view to the previous one, but showing the nut bearing on a face which is oblique relatively to the axis of the bolt.
  • the nut according to the invention comprises three parts, viz: a barrel I which is internally tapped and forms the nut proper, a skirt 2 and a web 3 which is perpendicular to the axis and connects the barrel to the skirt.
  • the barrel l is shorter than the skirt 2, as shown in'an exaggerated manner in Fig. 1, in which the nut is seen screwed on a bolt 4, but
  • a 5 number of slits may be provided in the nut which make the latter resilient.
  • the barrel may be slit parallel with the axis of the nut over its entire height, along one or a plurality of planes passing through the axis. 10
  • two diametrically opposite slits 6 and I of this kind have been provided, through which pass the section plane Ill-III of. Fig. 3.
  • Said slits impart resiliency to the barrel and help the latter to grip the bolt as explained above and 16 as seen in Fig. 4.
  • slits 8 In addition to said slit or slits in the barrel, other slits 8 maybe provided in the web 3 and in the upper part of the barrel and of the skirt. In the drawing one of same has been provided 20 along each of the angles of the nut. This imparts resiliency to the web 3 and considerably facilitates the downward movement of the central portion of the latter when the nut is screwed home, as seen in Fig. 4. 25
  • the nut according to the invention has a. great number of advantages with respect to ordinary nuts and with respect to the so-called self-locklug nuts which have been constructed hitherto. Such nuts are nearly always made in a plurality of parts, thereby considerably increasing their cost of manufacture or again said nuts have a special thread which is difficult to. construct and Said nut can furthermore be manufactured at' furthermore costly to manufacture, or again they are provided with looking projections which decreases their strength and makes their manipulation for screwing and unscrewing complicated and unpractical. There is nothing of this kind in the nut according to the invention, which furthermore has with respect to ordinary nuts the advantage of being lighter for the same size and of producing a particularly efilcient looking.
  • a particular advantage of the nut according to the invention is that it eliminates the necessity for using the ordinary resilient lock washer.
  • a self-locking nut comprising an inner tapped portion, an outer portion concentrically surrounding the inner portion and forming a skirt extending beyond the inner portion at one end, and. a web connecting said two portions together at the other end, said web being provided with a plurality of radial slits, and said inner portion being provided with a radial slit along its entire length.
  • a I self-locking nut comprising an inner tapped portioman outer portion concentrically surrounding the inner portion and forming a skirt extending beyond the inner portion at one end, and a web connecting said two portions together at the other end, said web and the inner and outer portions having radial slits, the slits along of the inner and outer portions being provided with slits out along diameters of the nut, and Said inner portion being also provided with slits along its entire length but on a diameter of the nut.
