Definitions

  • T0 aZZ'w/ wmit may concern Bq it known that I, JOHANNES Loosinof 3l harlstrasse, Cannstatt-Stuttgart, in the Kingdom of WVurttemberg, German'Empire,
  • Myinvention relates tomachine tools and more especially-to the means for controlling the feed of the tool into and out of operative position, and its particular object, is a mechanism ofthis kind which allows of throwing the tool, such as for instance the grinding wheel of a grinding machine provided with areciprocating tabla into operative position a short time before the table movement is being reversed, the movement of the feed gear being the same for each end position of the table, and therefor the tool being fed also the same tance.
  • a further object of my invention is the means for varying the tool feed at both end positions of the table either by an equal amount or by different amounts, there being also a chance left of'stopping the tool feed in one end position.
  • FIG. 1 is a front elevation and Fig. 2 avertical section, on the line AB, of the tool feed controlling mechanism.
  • Fig. 3 is a detail view of the reversing lever and pinion.
  • a is the reciprocating machine table
  • Z2 is one of two adjustable stops arranged on said table and designed, on being carried against the reversing lever c, to effect the reversal of the table movement.
  • Doublearmed lever 0 ispivoted to the machine bed at s and its lower arm is provided at its free end with a toothed segment d in gear with a toothed wheel 6 rotatably located on a pin 9 and carrying a double-armed lever 7.
  • a connecting rod 72, embracing the pin 9 carries a cross-arm 70.
  • Patent of WVilcoX, et aL, No. 1,197 ,7 00 As soon as the reversing lever 0 has returned to its initial position, spring it forces rod k and lever p back into their original positions. Now the other stop I) (not shown) in meeting lever 0 will move it the other way, thus causing lever f to be pressed against screw h and lever p whereby another feed movement is imparted to ratchet wheel r and to the tool.
  • a tool'feed ratchet gear anda connecting rod-of variable length connected, to it, two stops on said connecting rod, a doubleanmedlever adapted tocoeperate with either one orthe other of said stops and means influencedzby the stops on said table; for reversing said lever.
  • a reciprocatingtable two stops on said table, a too'l'feed ratchet gear and a connecting a rod connected" to it, aelasti'cjsmeans for varying the length .ofrsaidaconnectingrrod, two stops on said connecting rod,-..aildoublearmed lever adapted to cooperate with either one or the other of said stops and means influenced by the stops on-sai d table for reversing said lever.
  • double-armed ""lever adapted .to cooperate with either one or the' other of said: stops having 'itsfpivotal axis embracedlby the bifurcated end of the connecting rod, a
  • reversing lever adapted. to be. influenced by the stops on said table, a toothed segment on'said reversing-leverand a toothed wheel connected to said double-armed leveriandin gear with said toothed segment.
