TOOL-HOLDER.
Patented Oct. 17, 1905.
Application filed November 29, 1904. Serial No. 284,803.
To all whom it may concern.-
Be it known that I, CHARLES W. GRANT, a citizen of the United States, residing at Derby, county of New Haven, State of Connecticut, have invented a new and useful ToolHolder, of which the following is a specification.
This invention relates to the class of toolholders illustrated and described in Patent No. 667,350, granted to me July 2, 1901, and has for its object to simplify and cheapen their construction and to still further improve their operation in use.
With these ends in view I have devised the improved tool-holder which I will now describe, referring to the accompanying drawings, forming part of this specification, and using reference characters to indicate the several parts.
Figure 1 is aside elevation, partly in longitudinal section, illustrating the construction and mode of operation of my novel tool-holder; Fig. 2, a plan view corresponding therewith; Fig. 3, an end view of the body with the tool and locking-plunger removed, and Fig. 4 is a plan view of the locking-plunger detached.
A denotes the body of my novel toolholder, which may be of any ordinary or preferred type or design, and B a tool, the operative portion of which may be of any of the ordinary styles in general use. The tool comprises a base 10, having a rear face 11 and a depending shank 12. The body is provided at its forward end with an abutment 13, having a vertical hole 1 1, which receives the shank of the tool. Just above the abutment and back of hole 14. is a recess 15, lying at right angles to hole 14, in which a lockingplunger 16 is seated. The forward end of this plunger is provided with a face 17, which is adapted to engage face 11 on the base of the tool. Back of recess 15, in a plane at right angles thereto and communicating therewith, is a recess 18. As a means of forcing the locking-plunger forward to lock the tool in operative position I provide in recess 18 a plunger 19, having an incline or cam surface 20, which is adapted to engage a corresponding incline at the rear end of the lockingplunger. tends outward from the body and is provided with a thread which is engaged by a nut 21 to raise and lower the plunger, and thus move forward or release the locking-plunger. In the present instance the nut is shown as bear- The upper end of plunger 19 eX- ing upon the base of a recess 22 in the body. Plunger 19 is shown as made round and as retained against rotation by means of a pin 23, which is rigidly secured to or integral with the plunger and engages a slot 2 1 in the body. The locking-plunger is retained in the body by means of a set-screw 25, whose point engages in a slot 26 in the locking-plunger, the slot being of course made long enough to permit the slight longitudinal movement of the locking-plunger required in locking and releasing a tool.
The use of this tool-holder will be obvious from the drawings and description. By turning the nut backward from the locking position plunger 19 is allowed to drop downward slightly, which relieves the pressure of the incline on said pl unger against the corresponding incline on the rear end of the lockingplunger, and consequently relieves the pressure of the locking-plunger upon the base of the tool, leaving the tool unlocked, so that it may be readily removed by lifting the shank out of the hole in the abutment. To secure a tool in the holder, the operator simply places the shank of the tool in the hole in the abutment, allowing the base of the tool to rest upon the abutment, and then turns the nut downward, the effect of which is to raise plunger 18 and force the incline on said plunger against the corresponding incline on the rear end of the locking-plunger, which forces the latter forward and causes face 17 of the locking-plunger to engage face 11 upon the base of the tool. The cam action of the incline 20 is such as to cause the locking-plunger to be moved forward with great pressure, and the effect of the forward movement of the locking-plunger is to crowd the base of the tool forward and to cause the shank to bind in the hole in the abutment, thereby locking the tool firmly and rigidly to the holder without exercising great force on the nut 21. A slight backward turn upon the nut releases the pressure of the plunger upon the lockingplunger and of the latter upon the base of the tool, leaving the tool free, so that it may be readily removed.
Having thus described my invention, I claim-- 1. A tool-holder comprising a body having its forward end provided with a hole to receive the shank of a tool, said body having a recess 15 and a recess 18 at right angles thereto, a
locking-plunger in recess 15, the relative construction of the plunger and recess being such as to permit only longitudinal movements of the plunger, a plunger in recess 18 having an incline adapted to engage the rear end of the plunger, and means for moving the plunger into engagement With the locking-plunger whereby the latter is forced into engagement With the tool to lock the tool to the holder.
2. The combination With a tool-holder having a body provided With a recess 15, and with a recess 18 at right angles thereto, an abutment to form a support for a tool, and having a hole at right angles to recess 15, of a tool having an enlarged portion adapted to rest CHARLES W. GRANT.
