Abstract
Abstract A hand operated rope cutter for cutting metallic rope or cable. The cutter includes a pair of handles connected to each other for relative pivotable movement and a pair of reciprocatable cutting blades having opposed V-shaped cutting edges. The cutting blades are operated through a rotary actuating member which transmits pivotable movement of one of the handles into equal and opposite reciprocating movement of said cutting blades. The cutter has self-contained means for supporting itself in an upright position on a flat work surface to facilitate the application of greater leverage to the operating handle and for permitting ready measurement of the rope that is to be cut.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
140 words
A rope cutter comprising, in combination, a pair of handles, one of said handles having a head at an end thereof and the other of said handles being pivotably secured to said head, a pair of cutting blades having opposed cutting edges mounted within said head for opposite reciprocating movement, actuating means for moving said cutting blades between an open position for receiving a rope to be cut and a closed cutting position, said actuating means including an actuator member rotatably mounted within said head, first linkage means connecting said actuator member to said pivotable handle for imparting rotary movement to said actuating member in response to pivoting movement of said handle, and second linkage means connecting said actuator member to said cutting blades for imparting reciprocating movement to said cutting blades in response to rotation of said actuator member.
Claim 2
Dependent Claim
140 words
A rope cutter comprising, in combination, a pair of handles, one of said handles having a head at an end thereof and the other of said handles being pivotably secured to said head, a pair of cutting blades having opposed cutting edges mounted within said head for opposite reciprocating movement, actuating means for moving said cutting blades between an open position for receiving a rope to be cut and a closed cutting position, said actuating means including an actuator member rotatably mounted within said head, first linkage means connecting said actuator member to said pivotable handle for imparting rotary movement to said actuating member in response to pivoting movement of said handle, and second linkage means connecting said actuator member to said cutting blades for imparting reciprocating movement to said cutting blades in response to rotation of said actuator member.
Claim 3
Dependent Claim
29 words
The rope cutter of claim 1 in which said second linkage means includes a pair of toggle links each connecting one of said cutting members to said actuator member.
Claim 4
Dependent Claim
41 words
The rope cutter of claim 2 in which said toggle links are connected to said actuator at diametrically opposed points and cause said cutting blades to reciprocate in equal and opposite directions in response to pivoting movement of said pivotable handle.
Claim 5
Dependent Claim
21 words
The rope cutter of claim 1 in which said cutting blades have opposed V-shaped notches which each define two cutting edges.
Claim 6
Dependent Claim
34 words
The rope cutter of claim 1 in which said head and actuator member have aligned apertures through which rope to be cut may be passed when said cutting blades are in an open position.
Claim 7
Dependent Claim
51 words
The rope cutter of claim 1 in which said one handle head comprises a pair of longitudinal sections joined together along a common longitudinal plane, at least one of said sections being formed with a recessed area which defines an internal compartment for housing said cutting blades and said actuating means.
Claim 8
Dependent Claim
48 words
The rope cutter of claim 6 in which one of said sections is formed with a recessed area for containment of said actuator member for relative rotational movement and the other said section is formed with a recessed slot for receiving said cutting members for relative reciprocating movement.
Claim 9
Dependent Claim
49 words
The rope cutter of claim 1 in which said one handle has a support bar mounted near the outer end thereof, said support bar being selectively rotatable from a stored position in longitudinal alignment with said handle to a transverse position for supporting said cutter in an upright position.
Claim 10
Dependent Claim
45 words
The rope cutter of claim 5 including a measuring rod rotatably supported at one end adjacent said head aperture for selective movement from a stored position adjacent said one handle to a transverse position for measuring rope that is to be cut by said cutter.
Claim 11
Dependent Claim
56 words
The rope cutter of claim 9 in which said measuring rod has a selectively positionable marker mounted thereon, locking means for locking said marker in a selected position on said rod, and said measuring rod and marker being adapted to support said cutter in an upright position when said measuring rod is in a transverse position.
Claim 12
Dependent Claim
90 words
The rope cutter of claim 1 in which said one handle has a support bar mounted near the outer end thereof, said support bar being selectively rotatable from a stored position in longitudinal alignment with said handle to a transverse position for supporting said cutter in an upright position, a measuring rod rotatably supported at one end to said head for selected movement from a stored position adjacent said one handle to a transverse position for supporting said cutter in an upright position and for measuring rope to be cut.
