35 designates a cutting disk having on its peripheryV an annular cutting edge 36 and a central opening 37 through which extends the pintle 32, the arrangement being such that the disk 35l may freely rotate upon said pintle, between the nut 34 and the offset 31.
Upon the cross-bar 29, on opposite sides of the shaft 21 from the disk 35, is disposed a Asleeve 38 having threads 39 engaging the threads 23, and an annular flange 40. The sleeve 33 may be moved either outwardly or inwardly upon the cross-bar 29 by rotating it in the properv direction.
41 is a jam-nut engaging the threads 28 and adapted to be screwed up tightly 'against the free end of the sleeve 38 to prevent said sleeve from Vturning upon the cross-bar 29.
Upon the sleeve 38, intermediate the flange 40 and the nut 41,V is rotatably'mounted a relier 43, the functions of which will hereinafter be fully described. Y
rlhe die table 7 is provided upon its upper side with two spaced apart ribs 44, which extend transversely relative to the table and carry set screws 45, which engage opposite 'sides of a die 46 seated on said table between the ribs 44. rThe width of said die 43 is less than the distance between the ribs, thereby permitting the die to be shifted upon the table'so that it may be brought into proper alinement with the shaft 21 which it underlies.
After the die 46 has been placed in proper position on the die table 7, the screws 45 are intended to be turned Vup until they bear equally tight against its sides. kBy loosening the screws 45,Y the die may be removed fromthe table 7 and another, die substituted. Y 1
Upon the upper or face side of the diev46 is cut a central conicaly recess 47, which during operation of the cutter, receives a conical projection 48 at the lower end of the shaft 21, which is intended to assist in alining the die relative to the shaft 21 andthe cutting disk 35 before the screws 44 are tightened. rllhe die 46 is further provided Yupon Yits upper side with annular grooves 49, in either of which grooves the disk may be made to travel when the cutter is inoperation.
lVhile the `device illustrated showsa die provided with two grooves, it is to be understood that the die is not limited to any particular number of grooves, and that, if
desired, it may be constructed with only one groove, or it may have more than two grooves.`
By loosening the nuts 30, the cross-bar 29 ytween the die and the disk 35.
Ymay be rotated to shift it longitudinally of V29 above the die 46 so as to permit the sheet metal intended to be cut to be inserted be- The wheel 10 and screw 9 are then rotated in the opposite direction to'lower the shaft 21 and its cross-bar 29, until the disk 35 engages the said sheet metal, when by rotating the wheel y 25 the shaftl 21 will be made to rotate in the 'at times cause said metal to buckle up, and
in order to prevent orv limit said upward buckling of the metal, l have provided the roller 43, which is intended to roll along on the metal as the shaft 21 revolves, or it may be so constructed and arranged as to normally travel a slight distance above the metal and to engage the same4 only when it bends or buckles up.
Having described my invention, what l claim and Vdesire to secure by Letters Patent, is Y 1. A rotary sheet metal cutter comprising a frame having a pair of spaced apart outstanding brackets disposed in the same vertical plane, a vertically disposed screw carried'by the upper one of said brackets, a vertically disposed shaft rotatably and slidably carriedV by the other of said brackets, said screw and shaft being disposed in axial alinement with eachother and having one end pivotally connected together, a screwthreaded cross-bar carried by the free end of said shaft and having its ends extending at substantially right angles from opposite sides of the shaft, saidV cross-bar movable longitudinally in either direction by rotating it relative to the shaft, nuts on said crossdisposed screw carried by the free end of the ment with said screw and having its upper.
end movably connected to the lower end thereof, said shaft being movable both longitudinally and rotatably relative to ,itsV
bracket, a screw threaded opening extending horizontally through the lower end of said shaft, a screw disposed in said opening vand having its free ends' projecting outwardly a distance from either side thereof, a cutting disk rotatably mounted on one end of said last named screw, and means coperating with said disk for cutting-circular openings in sheet metal.
In testimony whereof, I have hereunto set my hand this `1st day of January, 1920.
