CUTTER HOLDER.
Application led April 17, 1925.
This invention relates to certain new and useful improvements in cutter holders, and the primary object thereof is to provide improved means for attaching cutters made of expensive high speed steel to holders which are made of cheaper steel, as distinguished from the common practice of the art of constructing the cutter and holder of an integral piece of high speed steel.
A further object of the invention is to provide improved means for centering and rigidly maintaining the cutter in the holder, and to also provide a holder which is of simple and economical urpose; which allows the cutter to be easily and quickly applied to and removed therefrom, and which is effective for its intended function.
The invention still further aims to provide a holder, which enables larger sized cutters to be adjustably held.
In the drawings Fig. l is a sectional View of the invention;
Fig. 2 is a side elevation of the holder per se, and
Fig. 3 is a section on line 3 3 of Fig. 1.
In proceeding in accordance with the prescnt invention, a holder 2O has a bore 21 threaded at its inner end at 22 and receiving therein the threaded inner end of a spring pin 23, the opening being of greater diameter than that ot' the p in. The outer end of the pin 23 is threaded at 24: and projects into conical-shaped outer end 25 of the bore. The outer end of the holder is formed with a series of longitudinal cuts or slots 26 and is exteriorly threaded and of cone-shape as indicated at to receive aclamping nut 27 thereon. A stop collar 28 is formed on the outer end of the holder at the inner end of the conical threaded part 30 thereof so as to provide a stop to limit inward movement of the clamping nut. The cutter 3l has a coneshaped inner end 32 which comformably en- Serial N0. 23,811.
gages the conical walls 25 of the outer end of bore 21. The pin 23 functions as a centering guide and also as a means to positively connect the cutter to the holder. Following inward screwing of the cutter, the nut 27 is rotated to draw the split parts of the outer endof the holder into tight engagement with the conical end 32 of the cutter, thus affordmg a firmer support for the cutter, the nut 27 also functioning to increase the thickness of the outer end of the holder and thereby impart a greater degree of rigidity thereto.
It will be apparent that the holder may be made of cheap material and may also be employed with cutters of varying forms.
Having thus described my invention what I claim as new and desire to secure by Letters Patent is In combination with a holder having a body formedwith an opening at one end terminating in a conical wall, a spring pin of substantially uniform diameter throughout threaded into said end of the body and having a threaded outer end, the opening being of greater diameter than that of the pin whereby the remainder of the pin is spaced from the opening, a cutter having a shank formed with an opening threadedly engaged with said threaded outer end of the spring pin and having a tapered portion conformably engaged with the conical wall of the body, the end of the body surrounding the opening being slitted to form fingers extending axially of the opening, and in register with the threads on the outer end of the pin, and a threaded nut engaged over the fingers to clamp same against the tapered portion of the cutter shank at points in register with the meshing threads of the pin and of the cutter.
In testimony whereof I have signed my name to this specification. v
JOSEPH M. REDINGER.
