Abstract
Abstract A portable rivetting machine of the type including a channel (20) for slidingly receiving a series of interconnected rivet elements (rivets, U-shaped staples and the like), a resiliently-loaded slidable pusher for pushing the series of elements towards a discharge end. The channel (20) is internally provided with more than one pair of longitudinal dividing walls (38, 40) extending up from its base wall so as to define pairs of interstices (50, 52) disposed symmetrically with respect to the centre line of the channel as well as a central interstice (54) extending along the centre line of the channel. Each pair of two interstices (50, 52) is arranged to receive the legs of a respective series of U-shaped staples (E i , E 2 ) of a width corresponding to the distance between the interstices themselves. The central interstice (52) is arranged to receive a series of rivets (E 3 ). The pusher (56) includes the same number of parallel blades (60, 66, 68) as the number of interstices with each blade being housed in an interstice itself. The blades are interconnected by a yoke (62, 68) above the upper edges of the dividing walls of the channel (20).

1 . Portable rivetting machine of the type comprising a channel, defined by a base wall and a pair of side walls, for slidingly receiving a series of interconnected rivet elements (rivets, U-shaped staples and the like), a resiliently-loaded slidable pusher for pushing the series of elements towards a discharge end of the channel where there is a slit for the discharge of the elements from the bottom of the channel, and a blade punch reciprocably movable through the slit to detach the elements one by one from the series and discharge them through the slit itself, characterised in that the channel (20) is internally provided with more than one pair of longitudinal dividing walls (38, 40) extending up from its base wall such as to define pairs of interstices (50, 52) disposed symmetrically with respect to the centre line of the channel as well as a central interstice (54) extending along the centre line of the channel, each pair of two symmetrically-disposed interstices being arranged to receive the legs of a respective series of U-shaped staples (E 1 , E 2 ) of a width corresponding to the distance between the interstices themselves and the central interstice (52) being arranged to receive a series of rivets (E 3 ), and in that the pusher (56) comprises the same number of parallel blades (60, 66, 68) as the number of interstices with each blade being housed in an interstice itself, the blades being interconnected by a yoke (62, 68) above the upper edges of the dividing walls of the channel.

1 . Portable rivetting machine of the type comprising a channel, defined by a base wall and a pair of side walls, for slidingly receiving a series of interconnected rivet elements (rivets, U-shaped staples and the like), a resiliently-loaded slidable pusher for pushing the series of elements towards a discharge end of the channel where there is a slit for the discharge of the elements from the bottom of the channel, and a blade punch reciprocably movable through the slit to detach the elements one by one from the series and discharge them through the slit itself, characterised in that the channel (20) is internally provided with more than one pair of longitudinal dividing walls (38, 40) extending up from its base wall such as to define pairs of interstices (50, 52) disposed symmetrically with respect to the centre line of the channel as well as a central interstice (54) extending along the centre line of the channel, each pair of two symmetrically-disposed interstices being arranged to receive the legs of a respective series of U-shaped staples (E 1 , E 2 ) of a width corresponding to the distance between the interstices themselves and the central interstice (52) being arranged to receive a series of rivets (E 3 ), and in that the pusher (56) comprises the same number of parallel blades (60, 66, 68) as the number of interstices with each blade being housed in an interstice itself, the blades being interconnected by a yoke (62, 68) above the upper edges of the dividing walls of the channel.
Claim 3
Dependent Claim
65 words
Rivetting machine according to Claim 1, characterised in that it includes two pairs of dividing walls (38, 40) for defining one pair of outermost interstices (50) and one pair of innermost` interstices (52) for the sliding of two series of different U-shaped staples (E 1 , E 2 ), as well as a central interstice (54) for the sliding of a series of rivets (E3)..
Claim 4
Dependent Claim
162 words
Rivetting machine according to Claim 2, characterised in that of the two pairs of dividing walls the outermost (38) have a greater height and the innermost (40) a lesser height with respect to the bottom of the channel, the outermost dividing walls being arranged to be slidingly embraced by a series of U-shaped staples (E,) of greater width and of lesser length, these staples being supported, by means of their yokes, on the upper edges of the outermost dividing walls, and the innermost dividing walls (40) being arranged to be slidingly embraced by a series of U-shaped staples (E 2 ) of lesser width and greater length, these staples being supported, by means of the tips of their legs, on the base wall of the channel, and the innermost dividing walls (40) being arranged to embrace with sliding coupling a series of rivets (E 3 ), these rivets being supported by means of their tips on the base wall of the channel.
Claim 5
Dependent Claim

Rivetting machine according to Claim 2 or Claim 3, characterised in that the channel (20) includes two sheet-metal elements (28, 34) with substantially U-shaped profiles, inserted one in the other to define the walls (30) of the channel and the outermost dividing walls (38) as well as the base wall, and two sheet-metal strips (40) which define the innermost dividing walls, these strips being provided with tabs (42) which pass through respective slits (44,48) formed in the base wall of the channel and which are upset to secure the strips and the profiled elements together.
