  • a fastener for use in the blind riveting of apertured members comprising a rivet having an annular head and a tubular shank frictionally telescoped over a self-plugging mandrel having a mushroom-like head and a stem, wherein the stem of the mandrel is -of reduced cross-sectional area over a neck region adjacent the head, so that when the head of the mandrel is pulled into the rivet, material from the rivet is forced into the reduced neck so as to lock the retained part of the mandrel in the rivet.
  • a fastener for use in the blind riveting of apertured members comprising a rivet having an annular head and a tubular shank frictionally telescoped over a selfplugging mandrel having a mushroom-like head and a stern, wherein the stem of the mandrel is formed, adjacent the mandrel head, with a neck of reduced cross-sectional area located between the mandrel head and a shoulder which latter has an external cross-sectional area substantially identical with that of the internal cross-sectional area of the rivet shank, the arrangement being such that when the rivet is upset fby pulling the mandrel 1he-ad into the rivet, metal passes from the rivet into the neck so as to lock the mandrel head in the shank of the rivet.
  • the mandrel is also formed with a breaker groove located between the said shoulder an-d a second shoulder spaced longitudinally from the first shoulder towards the pull-ing end of the mandrel.
  • the rivet may be externally of reduced cross sectional area over approximately that portion of its length intended to be within the thickness of the members t-o be riveted.
  • the neck of the mandrel is of eliptical cross section with the length of the major axis equal to the diameter of the main portion of the stem, the transverse dimensions of the neck region being preferably constant throughout its length axially Iof the stem.
  • the breaker groove may be of similar eliptical formation with the major axis of the elipse in a plane parallel to the major axis of the elipse of the neck, if not with said two axes parallel with one another.
  • the neck region may be of plain cylindrical or conical formation, or it may present a number of annular grooves with intervening ring-like portions of which the outer circumferential surfaces may be of cylindrical or tapered, for example, frusto-conical configuration.
  • the rivets and mandrels are offered for sale with the mandrels already forced into the corresponding rivets.
  • the shank of the rivet is crimped radially for a slightly greater length axially than the combined total thickness of the members, such as sheets, to be riveted together whereby the external and internal -diameter of the rivet shank is reduced at this region.
  • This crimping may be such that the rivet diameter is reduced uniformly continuously, or interruptedly at intervals only, around the circumference of the rivet.
  • the crimping may be such as to leave a plurality of longitudinal ribs spaced one from another around the circumference of the rivet.
  • the thickness of the ribs measured circumferentially of the rivet is small, and in a typical case there will be four in number.

  • a tubular rivet 10 has a head 11 and a shank 12 formed with a parallel bore 13 merging into a taper bore 14 towards the squared-off tail end 15 of the rivet.
  • the rivet 10 is adapted to be frictionally telescoped over a mandrel 16 of a self-plugging type which has an annular mushroom-like head 17 at one end and pulling portion 13 of a stem 19 at the other end.
  • the underside 20 of the head 17 of the mandrel 16 which, when the rivet 10 is fully telescoped over the mandrel 16 is brought to bear upon the tail end 15 of the rivet 10, has a curved surface 21 of a frusto-cone, the included section of the mandrel taken on angle of the frusto-cone being preferably of the order of 160.
  • the annular face of the underside of the head 17 may lie in a plane to which the axis of the stem 19 is at an angle of 90.
  • the mandrel 16 Adjacent its head 17 the mandrel 16 is formed with a neck 22 of reduced transverse dimension, the cross section of which is of eliptical shape.
  • the major axis 22a of the elipse corresponds to the full diameter of the main portion of the mandrel stem 19 whilst the minor axis 22b is substantially reduced.
  • the neck 22 extends for a short distance from the head 17 towards the pulling portion 18 of the mandrel 16, and merges into a shoulder 23 which has a diameter equal to the full diameter of the stern 19.
  • the stem of the mandrel 16 is further reduced in its cross section, which again is of eliptical shape, but the minor axis of the elipse being substantially smaller than the minor axis of the neck 22b to provide a breaker groove 24 which constitutes the weakest portion of the mandrel 16 and breaks when a pre-deter mined load on the mandrel is reached.
  • FIGS. 4a-4e Alternative embodiments of the mandrel according to the invention are illustrated in FIGS. 4a-4e in which the breaker grooves are of the same shape as that in the mandrel shown in FIGS. 4 and 6.
  • the mandrel shown in FIG. 4a differs from the one described in that the neck 25 of the mandrel 16 is of cylindrical shape the diameter of which is smaller than the diameter of the shoulder 23.
  • the mandrel illustrated in FIG. 4b is formed with a plurality of annular grooves 26 with intervening ring-like portions 27.
  • the diameter of the shoulder 27 is equal to the diameter of the main portion 19 of the stem 16.
  • the mandrel shown in FIG. 4c is similar to the one described in FIG. 4b except that the spaced ring-like portions 28 have tapered circumferential surfaces 28a thus forming sharp edges.
  • the neck 29 of the mandrel 16 shown in FIG. 4d is of conical formation diverging from the underside 20 of the head 17 towards the shoulder 23 into which the tapering portion 29 merges.
  • the mandrel shown in FIG. 4e has, immediately under the head 17, a short smooth portion 30 the diameter of which is equal to that of the stem 19 and is followed by longitudinal splines 31 formed by squeezing the material outwards to produce indentations.
  • the bore 14 of the tubular rivet 10 at the tail end is slightly smaller than the external diameter of the mandrel 16.
  • the mandrel stern being an interference fit (a forced t) in the taper bore 14 of the tubular rivet, to force the mandrel stern 19 into the rivet 10.
  • the underside 20 of the mandrel head 17 bears against the tail end 15 of the, rivet when the latter is fully telescoped over the mandrel 16 and the rivet mandrel assembly is then inserted into the aligned rivet holes 31 in sheets 32 and 33.
  • the rivet shank 12 is subjected to a high compressive stress which causes the surplus material at or near the tail 15 of the rivet shank 12 to flow into the neck 22 of the mandrel 16.
  • the remainder of the shank 12 is thickened so that the riveting hole 31 in sheets 32 and 33 is completely filled.
  • the breaker groove 24 yields and the mandrel breaks off. The broken portion of the mandrel falls away whilst the head 17, thte neck 22 and the shoulder 23 of the mandrel 18 are positively held axially and locked in the rivet 10.
  • Sheet thickness of material Crimping region to be riveted
  • the above crimping is such as to reduce the crosssectional area of the rivet uniformly around the circumference of the rivet. In the case of FIGS. l0, 11 and 12, however, the crimping is performed at four equal segments 38 around the circumference leaving four intervening longitudinal ribs 39.
  • the crimping of the rivet mandrel assembly as illustrated in FIGS. 10 and l1 improves still further the function in that the ribs 39 on the rivet shank 12 contribute to the better retention of the rivet 10 in holes 31 of sheets 32, 33 to be riveted when the rivet 10 is placed in these sheets for setting. Furthermore, with the rivet mandrel assembly of FIG. l0 a wider range of sheet thicknesses can -be effectively riveted with the same size rivet.
  • the breaker groove of the mandrel may have opposed flats intermediate its length, such as shown in FIGS. 8 and 9 of the drawing.
  • the sheet thickness was the maximum and in three other cases the sheet thickness was the minimum for the particular rivet. All these specimens have been subjected to water leakage tests under a fluctuating pressure of 0-20 p.s.i. whilst being subjected to temperature variation. So far, the temperature ⁇ has been cycled four times from room temperature to C. and twice from 15 C. to 100 C. During this cycling, the test pressure has been applied at a frequency of approximately 25 cycles per minute and in all, '70,000 cycles have been done without any trace of leaking under any of the conditions for any of the specimens.
