H. n. HAMILTON" CUTTER SHARPENING DEVICE. APPLICATION FILED JUNE 2!- 1911- 1,244,493. I Patented Oct. 30, 1917.
- HUGH mam-mew WEBSTER, "MKsshoHUsETrs.
, =ouzr'rnnssnamanmne nnvien;
" To all whom it may concern: I
Beit known that I, Hues a citizen of the Uni-ted statesfresiding at Webster, in the county of Worcestenand State of Massachusettahaveinvented new and useful Cutter-Sharpening Device, of which the following is a. specification. 1:
j This nvention relates to a. cutter sharpen- 'ing device designed for nanualoperation.
Many cutters andother small machine P ts r ui e f equ g ind n ardfia require that the ground ,facebe maintained at its original angle relatively to the other parts or facesgof the article. It is extremely difiicult to perform this grinding operation successfully. while-holding the article :intheir hand and pressing it against the facerof a The grinding wheel as is usually done. correct face angle is commonly attained only after repeated trials and after grinding away a needless amount of valuable material, thereby correspondingly reducing the life of the cutter.
It is the general object of my invention to provide a sharpening device by which the cutter will be supported in a definite position and can be moved in a fixed path past an abrasive member, thus sharpening the cutter at the original angle with no loss of time or material.
With this general object in view, an important feature of my invention relates to the provision of a fixed abrasive member, preferably having at least one straight face, and to the further provision of means for yieldingly forcing the cutter against said member and for holding the cutter in definite angular relation thereto during the sharpenmg operation.
In the preferred form of my invention the abrasive member comprises an emery stone or other similar sharpening device having a rectangular cross section and firmly secured in a supporting stand. The cutter is yieldingly held in a carrier movable longitudinally of the stand and parallel to one of the straight faces of the grinding stone.
My invention further relates to arrangements and combinations of parts hereinafter described and more particularly pointed out in the appended claims.
A preferred form of my invention is shown in the drawings, in which- Figure 1 is a plan view of my improved cutter sharpening device;
Fig. 2 is an end elevation thereof;

Secti nal el w po tioned a sha n n -1 0 ot e Qheld itu nal pes onrla r this and c amp ng e vt l5-- The s o e 1 13 is gprovidedmith a straight. substantially vertical face 18* which is engaged by the article-(to beiground.;-.- 1 1.
=Ehe stand 10 is cut away to provide a guide-way 16 within which a carrier 17 is longitudinally slidable. The carrier 17 is grooved transversely at 18 and a holder 20 is mounted to slide transversel of the carrier in said groove. The holder 20 is provided with a recess 21 adapted to receive a spring 22, the outer end of which engages a plate 23 secured to the carrier 17 and closing one end of the groove 18. At its opposite end the holder 20 is cut away to form a seat 2 1 for the cutter C which is shown in the drawings as secured by a screw 25. A handle or knob 26 is mounted on the upper side of the holder 20.
The operation of the device is extremely simple. The holder is preferably removed from the carrier while the cutter is secured thereto, the face to be ground being set at a right angle to the sides of the holder. The holder is then placed in the carrier, the spring 22 being compressed by pressure upon the handle 26 until the cutter slips freely past the stone 13. When the holder is in position in the carrier the spring is released and forces the cutter yieldingly against the face 13 of the grinding stone. The carrier 17 is then moved back and forth along the guide-ways 16 in the stand 10 until the face of the cutter C has been ground to the required extent.
During this operation the spring 22 keeps the cutter pressed against the grinding stone with the desired pressure and the cutter is held at a fixed angle to the stone dur: ing the entire grinding operation. If the cutter has been accurately placed upon the holder 20 it will be ground with a slight amount of labor and no waste of material.
While I have shown only one form of cute tGIhfilaillQs drawings it aiivill-l-be understood that the device is capable of use -With--3 wide variety of gu ttersg ndgtl er small aaw tic es.
