Definitions

  • My invention relates to tool holders shown in the accompanying drawings and more particularly described in the following specification and claim.
  • the primary object of the present invention is to provide a tool holder of simple and inexpensive construction in which a positive driving relation is obtained between the tool. and the holder.
  • a further object of the invention is to provide for material reduction in the cost of tools manufactured of high speed steel now upon the market by forming the tool with a relatively short slightly tapering shank, ground and fitted to the tool socket to insure accuracy of operation; the holder being constructed with interlocking means adapted to engage the shank of the tool to provide a positive driving connection between the tool and holder.
  • a further object of the invention is to provide for the rapid interlocking of the tool in the holder and for releasing the same therefrom as required.
  • a further object of the invention is to provide a device adapted to receive and support different tools as for example drills, reamers, counterbores, spot-facers or the llllu as required.
  • a further object is to provide a holder titted with positive driving means equally etl' ective for either metal or wood working tools and in carrying these objects into ef feet the tool holder is fitted with a driving pin having an enlarged head projecting from a counterbore in the wall of the holder into a longitudinal peripheral groove in the tapering shank of the tool, thus insuring a positive driving connection between the tool and holder in which the danger of shearing the driving pin'is reduced to the minimum.
  • the latter is constructed with a transverse which form a Serial No. 585,129.
  • Figure 1 is a side elevation of the holder with a drill inserted therein.
  • Figure 2 is a side elevation partly in section of the holder showing reamer engaged therein.
  • Figure 3 is a cross-sectional view taken on or about line 33 of Figure 2.
  • A denotes a tool having a relatively short slightly tapering shank A, fitted to the tapering socket B, of the tool holder B,
  • C is a driving pin having an enlarged head 0 projecting into the tool socket from a perforation B which is enlarged at its ends to form inner and outer shoulders B" and 13 respectively, adjacent the ends ot the perforation.
  • the shank C of the driving pin is slightly tapered and when driven into the wall of the holder from the inside of the socket its outer end is riveted as at C against the shoulder B that it may be rigidly secured to the holder;the outer end of the perforation is then filled with solder D, covering the riveted end of the pin flush with the outer surface of the holder.
  • B" is a tapering perforation extending transversely through the wall forming the socket of the holder, to receive a tapering pin (not shown) designed when driven into the perforation to bear upon the arched end of the tool shank wher by the tool may be released from the holder.
  • the transverse tapering perforation and the tapering pin inserted therein are so constructed in relation to each other that the pin cannot be driven completely through the holderwhich might result in the latter being lost the pin however is adapted to bear upon the arched top of the tool shank and thus release the tool from the socket of the holder.
  • the perforation for the driving pin C may be bored through the wall of the holder from the opposite side;-the pin C may then be inserted through the wall into its seat in the counterbored end of the perforation opposite thereto, the open perforation through which it was inserted may then be closed with solder.
  • a tool holder provided with a socket, the wall of which has a perforation enlarged at its inner and outer ends to form an inner and an outer shoulder adjacent the ends of the perforation, a tool having a shank fitted in the socket of the holder provided with a longitudinal groove extending from the end of the shank, and a pin inserted in the perforation from within the socket and having an enlarged head at its inner end fitting the enlarged inner portion of the perforation with the outer side of the head bearing against the inner shoulder of the perfora tion to prevent the pin from working 6X- teriorly through the wall of the socket and at its inner side projecting into the groove of the shank of the tool to provide a driving connection between the tool and holder, the outer end of the pin being riveted against the outer shoulder of the.
