Abstract

Device, knurling, characterized by consisting of a U-shaped body, on the inner edge of whose bridge there is a central longitudinal rib that, cooperating with a throat in a box piece, constitutes the sliding guide for said box, which is a carrier of a knurled knurling rotating roller, which is constantly moved in confrontation with two other analogous rollers mounted rotatable in the area of the inner edge of one of the branches of said u, said associated box carrying a spindle in such a way that it can rotate therein. But it is solidary in its longitudinal movements, whose spindle crosses the other branch of the u, constituted in nut for the same, ending externally in suitable handle for the grip and for the turn, arranging on the same spindle locking means such as nuts that pressing against the end of the nut configuration of the u, can produce a counter-nut action, all in such a way that the rotation of the spindle in its nut in one direction or another causes the sliding of the box approaching or moving away from its roller in relation to the other two rollers considered fixed axes of rotation, presenting the outer edge of the carrier branch, these rollers a blind threaded bore provided to receive the threaded end of a bar which, thus coupled, becomes a handle for the use of the tool in its work of the wheel.
