Abstract
Abstract Apparatus for cutting paper, card or the like, having a rotary cutter wheel which is movable along the lateral edge of an elongate fixed blade so as to cut or shear by a continuous scissors action, and in co-operation therewith, a friction drive wheel which rotatably drives the rotary cutter wheel as the cutter is drawn along the fixed blade, and a housing partially enclosing the cutter wheel.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
190 words
Apparatus for cutting paper, cards, and like material, said apparatus comprising, in combination, a base, an elongated, rigid cutting blade mounted on said base, an elongated substantially rigid member mounted on and spaced from said cutting blade, a housing member, a wheel member carried by said housing member, a cutting edge unitary with said wheel member positioned against and transverse of said fixed blade and projecting at least partially into the space defined between said blade member and said elongated member, means unitary with said wheel member and projecting at least partially into said space for positively forcing said cutting edge laterally against said fixed blade by cooperation with said elongated member in response to downward pressure on said housing as said housing and said wheel member are moved along said fixed blade to cut said paper like material in a scissors like action between said cutting edge and said fixed blade, and a Pressure wheel portion unitary with said wheel member for bearing against said material and holding said material in a substantially fixed position during the cutting thereof in a position in close proximity to the cutting operation.
Claim 2
Dependent Claim
190 words
Apparatus for cutting paper, cards, and like material, said apparatus comprising, in combination, a base, an elongated, rigid cutting blade mounted on said base, an elongated substantially rigid member mounted on and spaced from said cutting blade, a housing member, a wheel member carried by said housing member, a cutting edge unitary with said wheel member positioned against and transverse of said fixed blade and projecting at least partially into the space defined between said blade member and said elongated member, means unitary with said wheel member and projecting at least partially into said space for positively forcing said cutting edge laterally against said fixed blade by cooperation with said elongated member in response to downward pressure on said housing as said housing and said wheel member are moved along said fixed blade to cut said paper like material in a scissors like action between said cutting edge and said fixed blade, and a Pressure wheel portion unitary with said wheel member for bearing against said material and holding said material in a substantially fixed position during the cutting thereof in a position in close proximity to the cutting operation.
Claim 3
Dependent Claim
26 words
The apparatus of claim 1 wherein said forcing means comprises a unitary frusto-conical portion on said cutting wheel, said frusto-conical portion bearing against said elongated member.
Claim 4
Dependent Claim
26 words
The apparatus of claim 1 wherein said housing includes a pair of substantially upright slots, and said wheel member includes axle means received in said slots.
Claim 5
Dependent Claim
66 words
The apparatus of claim 1 wherein said housing includes an upright slot in one wall thereof, and a horizontal shoulder on the opposite wall thereof, said wheel member includes axle means received on said slot and on said shoulder, and means are provided for pivoting said housing about the upright axis of said slot in a substantially transverse plane relative to the axis of said slot.
Claim 6
Dependent Claim
43 words
The apparatus of claim 1 wherein said wheel member includes axle means, said housing is resilient, and a pair of depressions are provided in opposite walls of said housing for engaging said axle means so that said housing resiliently retains said wheel member.
Claim 7
Dependent Claim
46 words
The apparatus of claim 1 wherein said housing includes a bearing surface which bears against said elongated member, and means are provided on said housing and on said elongated member for releasably securing said housing to said elongated member, so that said housing is slidable thereon.
Claim 8
Dependent Claim
47 words
The apparatus of claim 1 including a base member, the space between said fixed member and said fixed blade comprising a slot in said base member, said fixed blade being on one side of said slot, and said elongated member defining the other side of said slot.
Claim 9
Dependent Claim
22 words
The apparatus of claim 1 including a pressure pad 18 positioned intermediate said pressure wheel portion and said paper material being cut.
Claim 10
Dependent Claim
16 words
The apparatus of claim 8 wherein said pressure pad is wider than said pressure wheel portion.
