Be it known that If, I-IynnMAn Isnnn, a citizen `of the United States, and a2 resi` dent of Norwoochin the county of Hamilton and State of- UhiO, `have invented certain new and useful Improvements in Cutter-Setting Indicators, of which the following isa full, clear, andI exact description, reference being had to` the. accompanying drawings, for-minga part of this specifica IOII.` i
liv/Iy invention relates tomeans for positioning a toothed cutterso that the teeth are in such angular relation to the grinding wheel that they may be properly sharpened with any predetermined amount of clear-` ance. I
It has heretofore been the custom of skil ful operators to follow clearance tables to effect the adjustment of a toothedJ cutter so that the teeth thereof will be in proper a`nguiar relationto the grinding wheel to give to the sharpened teeth the propercleara-nce angle. I am awarevalso that cutter setting indicators have heretofore been usedwherein scale graduations and indicators have beenV provided `between the head-stock of a grinder and a positioning pulley, whereby suitable adjustments of the nature above mentioned have been effected. In the adjustment of work on machines equipped with such indicators, however, it is first necessary to bring into registration the indicator and Zero mark of the scale graduations and to lock the pulley in such position, after which the cutter to be sharpened must be secured to the pulley in the precise position with reference to the grinding wheel which it is to occupy before adjustment through the desired clearance angle. It is one of the objects of my invention to provide a cutter setting indicator wherein the work may be mounted on the pulley and then rotated to the required position with reference to the grinding wheel, after which the indicator and zero marks may be brought into registration without disturb ing the position of the work. Other objects will appear from the following description of my invention.
In the drawings: Figure 1 is a plan of the head-stock of a grinder equipped with my new lcutter setting indicator.
lfig. 2 is a side elevation of said headstock.
Fig. 3 is a central section of a portion of the head-stock and spindle illustrating my invention.
Fig.` 4l is an elevation of zu grindingmaa chineshowing therelation of the head-steelt to the other mechanisnn The; numeral 1 indicates thewbase" of the head-stock of `a grinding machine. .l?iv otally supported on the base Iris an angle block 2, to one face of which the head 3 is pivotally secured. Journaled in thehead 3 isla spindle el. `Itetatably mounted oir the spindle 4e isa pulley 5; a setlscrew t5 is provided whereby said pulley maybe finedlysecured to the spindle if desiredn The parts thus far described'areof a form andwiconstruction familiar toithose skilled in the art. Secured to the spindle Ll, near the end thereof, is collar 7, a( flange 8 of whichis arranged `to fit into: an annular groove in the face of the pulley 5. Therear faceoft the pulley 5 is provided with al flange 9.`
The head 3 has a reduced endl 10, provid.- inga seat for a ring 11 which isarranged to be secured thereto by means of a thumb screw- 12. `The periphery of thering 11 as will be seen, is adjacent and: fluslr witlrthe `flange9oflthe pulley 5. Either on `thering 11 or the flange 9 are scale graduations 13, the same beingfshown in thepresentembodiment of the invention on the periphery of the ring 11. @n the flange 9, or on the ring 11, if the scale graduations be placed upon said flange, is a plurality of indicator marks 14, the same being sufficient in number so that one of said marks may be conveniently read from any position which the operator may be called upon to occupy during the performance of his work.
In Fig. Ll of the drawings, I have shown the head-stock constructed in accordance with `the foregoing description in its relationship to the other portions of a grinding machine. This machine comprises briefly a column 15 upon the upper end of which is a grinder head 16. Mounted upon said column 15 is a table 17, the said table carrying the head-stock heretofore described, and the usual tail-stock (not shown). The table 17 is adjustable in the usual manner so that work mounted between the head and tailstock, or upon the head-stock alone, may be brought into any desired relationship to the emery wheel 18, on the grinder head 16. A tooth rest 19 of ordinary construction is provided.
The operation of my cutter setting indica- .the art, from the foregoing manner by means ofdogs or a suitable chuck, the cuttingedgeof one of the teeth and the centers of the spindle 3a and the emery wheel 18 being brought into alinement. Y The operator next turns the ring 11, after loosening the thumb screw. 12, until the zero point or' 1 the scale registers with one of the indicators 14 on the iiange 9 of the pulley, having reterence in such operation to the position from which he 'may most :conveniently read the scale; in this position the ring is locked to the head by the thumb screw 12. The pulley 5 is then rotated so that the indicator 14 registers with the mark on the scale,rindicative of the degree of clearance to be given the sharpened tooth. The head-stock is next moved in the ordinary manner so that the l: positionfor grinding Y by Letters Patent is:
the combination with a e y(Topics .ofthis patent may be obtained for ve cents each, by addressing the cuttingv edge ofthe tooth is horizontally at right anglesto the grinding surface of the emery wheel at the point of contact. Subsequent teeth are readily brought into proper by bringing each tooth 1n succession to position on therest 19.
What I claim as new and desire to secure character described, head-stock and a cutter supporting member rotatably mounted therein, of an indicating member adj ustably mounted on said head-stock adjacent "said l. In a device 'of the cutter supporting member, and reciprocally adjustable therewith, and scale graduations and an indicator mark disposed between said indicating member and said cutter supporting member, substantially as and for the purpose described.
2. In a device of the character described, the combination with a head-stock and a cutter supporting member rotatably mounted therein, of an indicating member adj ustably mounted on said head-stock adjacent said cutter supporting member, and reciprocally adjustable therewith, scale graduations and an indicator mark disposed between said indicating member and said cutter supporting member, and means for locking said indicating member to said head-stock substantially as and for the purpose described.
3. In a device of the character described, the combination with a grinding wheel, a table, a head-stock, and a cutter supporting member rotatably mounted in said headstock, of an indicating member adjustably mounted on said head-stock and adjacent said cutter supporting mem er and reciprocally adjustable therewith, scale graduations and an indicator mark disposed between said indicating member and said cutter supporting member, and a tooth rest whereby subsequent adjustments of said cutter through said angle may be effected without reference to said indicator and graduations, substantially as and for the purpose described.
