Definitions

  • the present invention has reference to certain new and useful improvements in tool holders, and relatesmore particularly to a universal or multiple tool holder to be used in connection with lathes, planin shaping or the like machines, and the attachment essentially comprises a supporting member and a revoluble head thereon having a plurality of-tool clamps in which a corresponding number of tools are mounted, any one of which may readily be brought into operative position relative to the work piece by releasing' a latch bolt which normally relatively locks the tool holding head, rotating the latter until the required tool is opposite the work, and then locking the head again.
  • Each tool is secured to the revolver head by a stirrup-shaped clamping member, which clamps in turn are adjustably secured in elongated seat slots in the revolver head.
  • the supporting member l which is designed to be secured to the tool rest of the machine, terminates in a somewhat laterally disposed tubular bearing socket 2 with conically tapering inner wall.
  • the tool holding revolver head 3 is rigidly concentrically secured to a conical journal bolt 4 litting the bearing socket 2.
  • the nuts 4 serve to draw this journal bolt 4 fast into the bearing socket to prevent inadvertent relative movement.
  • the revolver head 3 is provided with a series (as shown, six) of obliquely extending elongated slots ll, and in its periphery are arranged, intermediate these slots, notches 5 with which cooperates the snap member or latch bolt 6.
  • the latter provided with a head 12, is guided within a casing 7 fixed to the support l, and is acted on by the compression snap into the respective spring 8 which tends to force the bolt into an alined notch 5.
  • the 'slots l1 are so disposed in the revolver head relative to the peripheral notches that upon the latch bolt 6 coacting with anotch the respectively oppositely disposed elongated slot extends rectangularly to the latch bolt or support member axis.
  • a stirrupshaped tool clamp 9 For each slot there vis provided a stirrupshaped tool clamp 9, whose laterally extending square shank portion 9 snugly titsy the receiving slot across its shorter diameter, so that relative rotary displacement is prevented. rI ⁇ he free shank end is threaded as at 9 and a flange nut 18 coacting therewith serves to clamp the tool V4 fast onto the revolver head.
  • a flange nut 18 coacting therewith serves to clamp the tool V4 fast onto the revolver head.
  • the clamp 9 with the tool l0 is moved by lhand into the required position until the tool properly faces the work piece and the nut 13-is then tightened up by means of a wrench,
  • a supporting member adapted to be secured to a lathe or other machine, ing revolver head having Vin coacting relation a series of peripheral notches and a corcomes opposite the a tool supportresponding number of elongated slots therethrough, screw and nut means allowing and preventing rotation of said revolver head on and relative t0 said supporting member, latch bolt means coacting with said peripheral notches for locking said revolver head in a plurality of predetermined operative positions, and a tool clamping member for each of said elongated. slots and adjustably securable therein, substantially as set forth.
  • a device ofthe character set forth a supporting member terminating in an enlarged laterally displaced bearing socket having a tapering bore, a tool carrying head in the shape of a disk with a conical journal bolt centrally extending therefrom and of a configuration conforming to the contour of the tapering socket bore, means for preventing and allowing relative rotation bebolt means on tween said conical bolt and said socket, said tool carrying head having peripheral notches and elongated slots therethrough,
  • ystirru-p-shaped tool clamps adjustably securable in said slots with capability of displacement therein in the longitudinal axis thereof but prevented from relative rotary displacement, and spring influenced latch the supporting member coacting with said peripheral notches in said tool carrying revolver head for locking the latter in various predetermined operative positions, said elongated slots being so disposed inthe revolver head that the slot receiving the clamp which binds the operating tool extends rectangularly to theaXis ofthe said supporting member.
