Apparatus for cutting disks from sheets

Claim 1

Apparatus for cutting disks from sheets of material comprising: a. a first clamping element having a flat surface disposed to engage one side of and support a stack of sheets of material from which said disks are to be cut, b. a second clamping element having a flat surface disposed to engage the other side of said stack of sheets, c. an elongated connector member having a hook-shaped end pivotally connected to a transverse pin carried by each end of said first clamping element with the other end of each said connector member being adapted to extend toward said second clamping element, d. releasable means connecting said other end of each said connector member to one adjacent end of said second clamping element, e. there being at least one opening through said second clamping element extending perpendicular to said sheets of material and being of a size corresponding to the size of the disks to be cut, f. a cutter member having inner and outer cylindrical surfaces with the outer cylindrical surface being of a size corresponding to the size of said opening through said second clamping element with the inner cylindrical surface being of a constant diameter and providing an unrestricted cylindrical chamber for receiving the cut disks and with said inner cylindrical surface at one end of said cutter member being beveled to provide an outwardly flaring annular surface which terminates in an annular cutting edge, and g. means operatively connecting the other end of said cutter member to rotary power means.
