- ROTARY 'GLASS CUTTER.
Application T 'oZZ whom it may concern:
Be it fknown that I, CARL F. DOERR, a citizen ofthe United States, and a resident of Yonkers, in the county of VVestchester and State of New York, have inventedv a new and Improved Rotary GlassCutter, of
which the following is a full, clean-and exact description.
This invention has relation to glaziers implements and. has particular reference to an improvement in rotary glass cutters of the type set forth in my co-pending'application Serial No. 463,693,. filed April 22, 1921. 1 The present invention contemplates an specifically refers to an improved-means for circumferentially adjusting the cutter head on the carrier sleeve therefor to simplify th'e construction of said means and the operation of bringing the various disc cutters into operative relation to the surface tobe cut.
in View, the invention resides in the novel constructlon set'forth in the following specification, particularlyvpointed out in the appended claims. and illustrated in the accompanyingdrawings, it being understood that thegright'is reserved toembodiments other than those actually illustrated herein tothe full extent indicated by the general meaning of-th'e terms in which the claims are expressed. I
In-the drawings Figure 1 is a plan view-ofthe improved -rotary iglass cutter with the cutter head shownin section.
Fig.2 isa side elevation of the same. Fig.3 is a transverse 860131011 taken approximately on the line 33 of Fig. 1.
Fig. 1 is a fragmentary longitudinal sectional view of the. adjustable cutter head illustrating the-manner in which the same is uncoupled from the carrier sleeve to permit .of its adj ustment.
Fig. 5 is afront face, view of the cutter head removed from the carrier sleeve.
Referring to 'the drawings by characters, 10 designates the base of the improved rotary-glass cutter which is provided on its under side withalining 11 of felt or any other suitable material adapted tores't upon "the surface of the glass 12 to be cut into a circul=ar shape as willbe hereinafter more ,fullygexplained. The hase 10 is provided.

Specification of Letters Patent. Pat nted Aug. 1, 1922,
filed January 14,1922. .Serial No. 529,183. I
a reduced threaded upper extre1nity14. bearing member 15 ismounted upon the uping movements and is retained against upward-movement by a nut 16 threaded on-the upper reduced extremlty 14 of the-bearing post or pivot. The pivot orpost 13 with its reduced extremity 14 provides a shoulder 17 located a short distance abovethe top of the bearing member 15 to form an abutment for the nut 17, whereby to allow free turning movement of the bearing member '15 without binding the nut. l
The bearing member l 5 is provided to one,
23 extending in the opposite direction from the pivot 13. By the arrangement described the cutter carrier 20 is mounted for vertical swinging movements on thebearing member 15 which latter is mounted,to'turn on the vertical pivot 13. Thenut 16 ispreferably concave on the upper sideto form a finger hold by means of. which the operator may press the base 10. into'firm contact with the surface of the glass 12 during the cutting operation without interfering with the free.
rotation of the cuttercarrier 20.
A. supporting-sleeve 25 having a square bore-26 corresponding to the size and shape standing post or pivot for horizontal turnof the-cutter carrier 20 is mounted thereon, I
.for longitudinal sliding movement and is adapted to'be adj ustably' secured in place by a set screw 27 or any vother suitable fasten- The sleeve is provided at its inner end with acirc'umferential flange 28 and an enlarged peripheral bearing portion 29 which isthrea'de'd as at 30 adjacent its juncture with thef'major portion of the sleeve proper. The 'cutterhead .31 is in'the nature .of an annulus which "snugly "fits over the enlarged peripherahportion 29fof the"carrier sleeve 25 and is provided with a pjeripheral or circumferential groove 32 in which the disc cutters 33 are mounted and 'circumfe'rentially spaced. The "flange 28 is provickdwit'h a laterally p'rcje ctiirg; l cekin I one of the key-ways'35.
' key 3e and the cutter head with a plurality of circumferentially spaced key-ways= 35 adapted to selectively receive the locking key 34 to position and arrange one of the disc cutters in cutting relation tothe glass. A retaining nut 36 is threadedly engaged with the threads 80 to retain the cutter head 31 into engagement with the flange 28 and the locking key 34 in locking engagement with When it is desired to bring another. of the cutting discs 33 into operative position, the locking nut 36 is unscrewed as illustrated in Fig. l to permit axial shifting ofthe cutter head. and relative separation of the same from the flange 28 whereby the key-way 85 will be, disengaged from'the' locking key I This, uncouples the cutter head 31' from the carrier sleeve to permit free circumferential movement of the same thereon whereby any of 7 said key-ways maybe brought into registry with the locking key 34. VVhen-the desired i adji 1stn1ent has been obtained the cutter head 31 isadvanced toward the flange 28 and the nut 36jis again threaded thereagainst to retain. the cutter head in its adjusted position.
The set screw '27 which ,afFOrds means for locking the sleeve 25 in its longitudinal adfjusted positions on the carrier bar 20, also functions as a stopfor engagement with the nut 36 to prevent the entire unthreading of the same from the threads thereby eliminating the'trouble incident to re-engaging the threads and also preventing possible stripping of the same. Under this arrangement the disc cutters which are here illus trated as six in number are designed to be I used one at a time and when dull the cutter head can be readily; adjusted on the sleeve to bring anotherof the cutters into cutting position. When all the cutters have become dull theycan be readily removed from the cutter head 81 and replacediby new ones.
' 1. In a cutting implement having a plurality of cutters adapted to'be selectively brought into cutting relation, embodying a cutter bar, a carrier sleeve longitudinally adjustable thereon, a stationary abutment at one extremity thereof, an axially movable abutment thereon, a cutter head mounted for j axial' and rotary movement on the sleeve'be ,tween said abutments having circumferentially spaced cuttersprojecting from the periphery thereof and interengageable means on the confronting, faces of the stationary abutment and :-the cutter head adapted to lock. said elements against relative axial and V rotary movement upon clamp ng engagement of said cutter headbetween the stationary and movable abutments.

4;, In arota-ry glass cutter, a cutter bar, a sleeve mounted for longitudinal adjustments on said cutter bar, a set screw threaded transversely through said sleeve for securing the same in. its longitudinally adjusted positions on the 'cutterbar, a cutter head provided with circumferentially spaced cutters projecting from the periphery thereof, the
latter being mounted for rotary and axial noverhents on the sleeve, and means for securing said cutter head in itsad usted position on the sleeve to selectively dlspose one of the cutters in cutting relation, comprising a peripheral abutment at one end of the i? sleeve, an inwardly projecting locking key on said abutment and a portion of said'cutter head having an annular series of axially disposed key-ways adapted to selectively receivethe locking key, and anut threaded on the sleeve for. axial. movement to afl'ord means for advancing the cutter head toward the abutn1ent, the said set screw coacting with the nut to prevent complete unthread-- I mg of'the same from the sleeve. I 5. The combination with a rotary glass cutter including a base adapted'to rest on and retaining the same in engagement with the glass and having. an upstanding pivot, a
bearing member mounted for complete rotation on said pivot, a counterbalanced cutter bar pivoted to saidbearingmember, a cutting elementadjustably mountedonthe cutterbar comprising a sleeve mounted for longitudinal adjustments on saidcutter b'ar,
- a cutter head provided with circumfere'n- 13G tially spaced cutters projecting from the peflange, a portion of said cutter head having riphery thereof and mounted for rotary and an annular series of axially disposed key- 10 axial movements on the sleeve to selectively Ways for selectively receiving the locking bring the cutters in cutting position, of key, and axial movable means for advancmeans for securing said cutter head in ading the cutter head toward and retaining justed positions on the sleeve embodying a the same in abutting engagement with the peripheral flange at one end of the sleeve, an flange.
