Abstract

Portable riveter, of the type comprising a channel, defined by a bottom wall and a pair of lateral edges for the reception and sliding of series of rivet elements (nails, U-shaped metal tips and the like) joined together, an impeller slidable, elastically loaded, to drive the series of elements towards an end of expulsion of the channel, end where there is a slit of expulsion of the elements from the bottom of the channel, and a laminar punch, moving alternately through the slit, to detach the elements one by one from the series and expel them through the slit, characterized in that the channel (20) comprises within it more than one pair of longitudinal partitions (38, 40) extended from the bottom wall and such that define pairs of interstices (50, 52) arranged symmetrically with respect to the perpendicular bisector of the channel, as well as a central gap (54) extending along the perpendicular bisector of the channel, and each pair of two in symmetrically disposed termites is apt to receive the stems of a respective series of U-shaped metal points (e1, e2) of width corresponding to the distance between said interstices, while the central gap (52) is apt to receive a series of rivets (e3) ); and in that the impeller (56) comprises a number of parallel lamellae (60, 66, 68) equal to the number of interstices and each of them contained in the respective gap, which lamellae are joined together by a yoke (62, 68) above the upper edges of the channel partitions.
