I represents a retaining nut, tapped to receive the threaded end of the shank, to secure the collar H in position.
J denotes a driving key projecting from a longitudinal groove 7' formed in the socket portion C and secured thereto by rivets or other engaging means.
K indicates a co-operating element adapted to receive the tapering shank L of a boring or other tool. The shank L is provided with feathers L having parallel outer faces adapted to enter corresponding recesses M in the tapering socket M of the tool holder, thereby providing a driving connection between the same.
N designates a tubular shank provided with a longitudinal groove N adapted to receive the driving key J of the co-operating portion of the holder A. The tubular shank is also tapped at bl to receive the shaft D of the connecting element.
P denotes an adjustable shaft, screwed into the wall of the tubular shank, provided at its lower end with a relatively wide gear P in mesh with a plurality of planetary gears Q, journalled in peripheral recesses formed in the wall of the tool holder. P indicates an extension of the shaft P adapted to bear upon the end of the tool shank.
R indicates a manually rotatable collar formed with an internal annular gear R in mesh with the planetary gears Q.
S denotes a nut screwed upon the shank of the holder adapted to retain the rotatable collar R in position.
T indicates a split ring encircling the nut having one end T bent inwardly that it may enter a recess in the shank of the holder to secure the nut against accidental release.
Having now indicated the several parts by reference letters the construction and operation 10f my invention will be readily understooc The upper portion A of the tool holder is first engaged to the spindle of a drill press or like machine,the lower co-operating portion of the holder is then fitted with a tool, as for example that indicated in Figgure 11,-the projecting feathers L of which enter the recesses M in the socket of the holder. The tubular shank N of the element K is then inserted in the socket C of the upper cooperating element,-the key J of the latter entering into the longitudinal groove N of the tubular socket. The shaft D is then screwed into engagement with the threaded end la of the lower portion of the holder. Y
To take up any wear that may occur in the tool the collar G is manually rotated,
thereby turning the shaft D through the cooperation of the planetary gears H,the element K and the tool carried therein being thus raised or lowered and thereby adj usted relative to the upper supporting member and the work] When it is desired to remove the tool from the socket of the lower member K the collar 1% rotatedits annular internal gear rotating the planetary gears Q, thereby causing the shaft P to move downwardly between the planetary gears with which it remains in meshits end P bearing against the end of the tool shank, forcing the latter outwardly and thus releasing the tool.
To detach the lower portion K from itsv co-operating supporting member A, the collar G is rotated so as to disengage the shaft D from the screw threaded end of the tubular shank N of the lower member, whereupon the lattermay be removed from the socket of its co-operating element.
Having thus described my invention what I claim is:
1. A tool holder of the character described, comprising two cooperating detachable interlocking members operating as a single unit, one of which has means adapted for driving connection with a power operated machine also means to receive and support the other member,in turn adapted to sup port a cutting tool; means adapted for l0ngitudinally adjusting said members while remaining in interlocking relation with each other and means carried by one of said memhere for forcing the tool carried thereby from its supporting socket each of said means including a screw and gearing for rotating the screw.
2. A tool holder comprising two cooperating detachable slidably interlocking members adapted to operate as a unit, one of said members having means adapted for driving connection with a power operated machine and also means to receive and support the other member, in turn adapted to receive and support a cutting tool .in driving relation therewith; a rotatable shaft carried by said first named member adapted to engage the second member; means for manually rotating said shaft, whereby the second member may be adjusted longitudinally in relation to the first member and means carried by the second member adapted to bear upon the end of the tool, whereby it may be released from the socket of said member, said means including a screw and gearing for rotating the screw.
3. A tool. holder comprising two cooperating members adapted to operate as a unit and arranged in longitudinal alignment, one of the members forming an extension of the other member and having a shank fitting within and slidably interlocked with the same, one of said members having means adapted for driving connection with the spindle of a power driven machine and the other member being adapted to receive a cutting tool in driving relation thereto, means adapted for longitudinally adjusting said members while remaining in interlocked relation with each other, said means includ ing a screw and gearing for rotating the screw, a longitudinally movable shaft carried by the tool supporting member, and manually operated means having a threaded shaft arranged to engage the end of the tool to release the latter from the member supporting it.
4:. Adevice of the character described, comprising a member having a tapering socket and grooves to receive the tapering shank and fins of a cutting tool, said member having an interiorly threaded portion; a shaft provided at one end with a relatively wide gear and threaded at its opposite end to engage the interiorly threaded portion of said member; planetary gears journalled in peripheral recesses provided in said member in mesh with said gear; and a manually ro tatable collar with an internal annular gear in mesh with said planetary gears, whereby upon rotating said collar the shaft may be longitudinally adjusted to bear upon the end of the tool shank to force the latter from the socket of said member.
In testimony whereof, I sign this specification.
JOHN HUGO SMITH.
