A method and tool (15) for securing V-shaped, open connector elements (14) o belt ends (1) in a manual operation use staples (8) that are driven by hammer blows applied to a punch held by the tool. Each connector element (14) has at least two shanks (11, 12) and at least one eye loop (13) interconnecting the shanks. The staples (8) are initially held in place for the driving by one shank (11) of the connector elements (14). The securing elements (8) first penetrate holes in one shank (11), then the belt end (1), and then holes in the shank (12), whereupon the free end pieces (53, 54) of the staples (8) are bent over in the tool provided with a die (29) for this purpose. The connecting elements (14) have downwardly projecting shanks (12) which extend initially away from the belt end. These shanks (12) are first pressed against the belt end (1) with a manually produced force increased with the aid of a tool mechanism providing a mechanical advantage. Then the staples (8) are driven by the hammer blows and finally bent over.
An apparatus for securing connector elements (14) by staples (8) to a belt end (1), said connector elements (14) having a first shank (11), a second shank (12) angled away from said first shank (11) and an eye loop (13) interconnecting said first and second shanks (11, 12), said staples (8) having free staple ends (53, 54) interconnected by a cross-piece (8A), said apparatus comprising a tool guide rail (6) having holes (7) therein for holding said connector elements (14) and said staples (8), a tool (15) movably guidable on said guide rail for movement along said guide rail (6), said tool (15) comprising a first tool section (16) movable along said guide rail and a second tool section (17), at least one guide member (27) interconnecting said first and second tool sections (16, 17) for guiding a relative movement between said first and second tool sections, a punch (20) movably carried by and guided in said first tool section (16) for operation by a hammer, a manual drive (19) carried by said first tool section (16) and connected to the second tool section (17) for manually driving said relative movement between said first and second tool sections, and wherein said second tool section (17) has a tool portion for moving at least said angled shank (12) against said belt end (1) in response to said relative movement between said first and second tool sections, wherein said manual drive (19) comprises at least one hand lever (36) connected to said first tool section (16) and at least one guide rod (37) connecting said hand lever (36) to said second tool section (17) so that said hand lever (36) is movable between two positions through a dead point position, a first journal (38) journalling said hand lever (36) to said first tool section (16), a second journal (40) journalling said guide rod (37) to said hand lever (36), and a third journal (41) journalling said guide rod (37) to said second tool section (17) to form a tilting drive, said apparatus further comprising at least two die depressions (29', 29") positioned in said second tool section (17) for cooperation with said punch (20) to simultaneously drive two staples whereby free staple ends (53, 54) of one staple (8) of said two staples are bent initially toward said belt end while free ends (53, 54) of the other staple of said two staples are simultaneously completely bent into a finished connector locking position.
