  • HANS DISTLER OF FEUERBAGH, NEAR STUTTGART, GERMANY, ASSIGNOR TO THE FIRM SPEZIAL-WERKZEUG-EABRIK FEUERBAGH-G. M. B. 1-1., OF FEUERBACH, GER- WRENCH WITH HEAD HINGED ON THE SHAFT AND WITH REVERSIBLE RATCHET MECHANISM.
  • ⁇ Vrenches have become known in which a head is connected with a shaft by an adjustable joint, a feed mechanism reversible for movement in right or left direction being arranged in the head. It has further become known to arrange in feed mecha nisms of the type mentioned the pawls. which have an inclined back, in the head parallel to the axis of rotation in a circle around the same and to hold them by means of pressure springs in engagement with corresponding notches in the joint.
  • all the pawls of the feed mechanism are turned in the same direction and engage with the notches of the feed mechanism.
  • all the pawls are reversed at the same time for reversing the direction of movement.
  • the pawls have on part of their circumference teeth with which engage teeth in the inner surface of the adjusting ring.
  • Fig. 1 is a vertical section.
  • Figs. 2 and 3 show in plan view the feeding mechanism in the position for movement in right hand direction or left hand direction respectively.
  • feed pawls f In the head piece 0 rotatably connected to the joint element 6 by a screw (1 a number of feed pawls f are arranged. These feed pawls consist each of a bolt f shiftably mounted in one of a number of bores which are arranged in the head piece 0 in a circle around the central axis ofthe same.
  • the bolts 7 are permanently pressed upward by the action of pressure springs g,'and the upper ends of said bolts engage with notches 72 arranged in the lower end'face of the joint element 1), and adapted to be brought into register with the bores in the'head piece.
  • the upper portion of the bolts f is bevelled on one side and said bolts have grooves 7 in a portion of their circumference. a tooth being formed by every two consecutive grooves. With these grooves i engage teeth t: on the inner circumference of an adjusting ring a.
  • the inner teeth of the adjusting ring e exor pawl rotate 180. The portion-between.
  • these toothed portions are smooth and the ends of the smooth portions limit the rotation of the adjusting ring and consequently of the bolts or feed pawls.
  • a Wrench comprising in combination a shaft, a head piece, a joint element having notches and connecting said head piece with said shaft, an adjusting ring between said head piece and said joint element, teeth on the inner surface of said adjusting ring,
