Patented July 4, 1922 MIN* num/5885s yany one of the cutters 44 can be moved into lowermost cutting position, and after tlus adjustment has been made the cutter "head 43 is fastened in position on the sleeve 40.
" spending notch 48 with thescrew 50 and at For this .purpose the hub 42 ofthe-@cutter head 43 is provided with notches 48 extendiiigh longitudinally and spaced equal dis-` tances apart circumferential-ily in alinenient.
with the corresponding axles or shafts carryingi the cutters 44.V The sleeve 4.0 1s provideI withV an upwardly extending screw "(50 on which screws` a nut 51, andthe said screw l50y isadapted to engage any one of the notches .48 after 'the cutter head 43 :has

`When Athe desired notch. 48 -i-s in .engagement A with the screw 5.0 then the nut 51 is screwed .down t0 fasten the cutter head 43 to the sleeve 40. 'It is understood that on moving the sleeve 4() lengthwise on. the carrier 27 the cutting edge of the cutter 44 iny bottom.- position atthe time is a .desired distance from .the axis of thepivot 15 to .cutthe disk. a vdesired size. 1n order to aid= the glazier or .other .person using ,the vrotary glass cutter .1toaccu` rately set vthe cutter for cutting a disk .of-the desired diameter the har forming the ,carrier 2,? is,V preferably 'graduated with a 1li-near ifeasurement, as plainly indicated in Figure l.
VFrom the ,the arrangement described the user of the rotary glass cutter can readily. adjust Va cutter-head 43 ,to cut a glass disk of anydesi-red diameter.- By providing their head 269i the .cutter .carrier 27 with a counterbala-neing `weight 130, the cutter carrier 27 andthe cutter head 43 mounted thereon are counterb-al- 'vaneedfto permit of readiflyswinging the cutyter carrie r around vfor the lowermost cutter 44 to ont. into .theglass 1.2.
