Abstract
Abstract An apparatus 10 for safely cutting cordage has central frame members 11 that defines a cord working space 17 in which a cutting blade 33 having an elongated cutting edge 34 is mounted. Spring biased blade guards 40 are mounted on each side of the blade which are movable between a position shielding the blade cutting edge and a position exposing the blade cutting edge. A length of cordage is manually cut by drawing it against the blade guards and forcing them from their blade edge shielding position to their blade edge exposing position and then drawing the cordage over the exposed blade edge.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
169 words
Apparatus for safely cutting cordage and other elongated materials comprising, in combination, a frame at least partially defining a transverse opening therethrough, said frame having a top wall defining an upper boundary of said transverse opening; a blade mounted to said frame with an elongated cutting edge positioned within said frame opening; a pair of side shields mounted for movement straddling said blade between a position shielding said blade cutting edge and a position exposing said blade cutting edge and spring means biasing said side shields towards said blade edge shielding position, whereby cordage may be safely cut by drawing it against the side shields in their blade shielding position and forcing the shields to their blade exposing position, and drawing the cordage over the blade until it is severed whereupon the side shields are returned by the spring means to their blade shielding position, and wherein said side shields have in-turned top flanges that may engage said frame top wall under the bias provided by said spring means.
Claim 2
Dependent Claim
169 words
Apparatus for safely cutting cordage and other elongated materials comprising, in combination, a frame at least partially defining a transverse opening therethrough, said frame having a top wall defining an upper boundary of said transverse opening; a blade mounted to said frame with an elongated cutting edge positioned within said frame opening; a pair of side shields mounted for movement straddling said blade between a position shielding said blade cutting edge and a position exposing said blade cutting edge and spring means biasing said side shields towards said blade edge shielding position, whereby cordage may be safely cut by drawing it against the side shields in their blade shielding position and forcing the shields to their blade exposing position, and drawing the cordage over the blade until it is severed whereupon the side shields are returned by the spring means to their blade shielding position, and wherein said side shields have in-turned top flanges that may engage said frame top wall under the bias provided by said spring means.
Claim 3
Dependent Claim
22 words
The apparatus of claim 1 wherein said frame top wall has a channel therethrough canted with respect to said elongated cutting edge.
Claim 4
Dependent Claim
23 words
The apparatus of claim 1 further comprising a pair of side panels rigidly mounted to said frame beside said pair of side shields.
Claim 5
Dependent Claim
113 words
Apparatus for cutting cordage comprising a frame; a blade rigidly mounted to said frame and having an elongated cutting edge along which cordage may be manually reciprocated and cut; a pair of side shields mounted to said frame for movement beside said blade between positions shielding and exposing said blade elongated cutting edge; and spring means biasing said side shields towards said blade shielding position, and wherein a portion of said frame extends over said blade cutting edge and is formed with a channel through which cordage may be passed into contact with said side shields, and wherein said side shields are biased by said spring means into engagement with said frame portion.
Claim 6
Dependent Claim
113 words
Apparatus for cutting cordage comprising a frame; a blade rigidly mounted to said frame and having an elongated cutting edge along which cordage may be manually reciprocated and cut; a pair of side shields mounted to said frame for movement beside said blade between positions shielding and exposing said blade elongated cutting edge; and spring means biasing said side shields towards said blade shielding position, and wherein a portion of said frame extends over said blade cutting edge and is formed with a channel through which cordage may be passed into contact with said side shields, and wherein said side shields are biased by said spring means into engagement with said frame portion.
Claim 7
Dependent Claim
34 words
The apparatus of claim 4 wherein said side shields are formed with in-turned flanges that substantially completely block an end of said frame portion channel with said side shields biased against said frame portion.
