Abstract
Abstract A machine for cutting of the end of rod-like articles such as a rolled-up window shade. The article is held stationary and protrudes through a hole in the center of a flywheel, and a knife suspended from a lever pivoted on the flywheel cuts around the periphery of the article. A weight on the opposite end of the lever forces the knife against the flywheel by centrifugal action as the flywheel rotates.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
125 words
A machine for cutting rod-like articles into required lengths, comprising: a. a fly-wheel rotatably mounted on a machine base; b. a cradle of angular cross-sectional shape, in which an article to be cut may be rested, mounted on the machine base by means enabling elevational adjustment of the cradle to bring and hold the longitudinal axis of said article into substantial co-incidence with that of the fly-wheel; c. a first order lever eccentrically fulcrumed on the fly-wheel so that the lever may turn about its fulcrum in a plane normal to said fly-wheel axis; d. a knife on one end of said lever; e. a weight heavier than said knife on the other end of said lever; and f. drive means for rotating said fly-wheel.
Claim 2
Dependent Claim
125 words
A machine for cutting rod-like articles into required lengths, comprising: a. a fly-wheel rotatably mounted on a machine base; b. a cradle of angular cross-sectional shape, in which an article to be cut may be rested, mounted on the machine base by means enabling elevational adjustment of the cradle to bring and hold the longitudinal axis of said article into substantial co-incidence with that of the fly-wheel; c. a first order lever eccentrically fulcrumed on the fly-wheel so that the lever may turn about its fulcrum in a plane normal to said fly-wheel axis; d. a knife on one end of said lever; e. a weight heavier than said knife on the other end of said lever; and f. drive means for rotating said fly-wheel.
Claim 3
Dependent Claim

A machine for cutting rod-like articles into required lengths, comprising: a. a fly-wheel rotatably mounted on a machine base; b. a cradle of angular cross-sectional shape, in which an article to be cut may be rested, mounted on the machine base by means enabling elevational adjustment of the cradle to bring and hold the longitudinal axis of said article into substantial co-incidence with that of the fly-wheel; c. a first order lever eccentrically fulcrumed on the fly-wheel so that the lever may turn about its fulcrum in a plane normal to said fly-wheel axis; d. a knife on one end of said lever; e. a weight heavier than said knife on the other end of said lever; and f. drive means for rotating said fly-wheel.
Claim 4
Dependent Claim
125 words
A machine for cutting rod-like articles into required lengths, comprising: a. a fly-wheel rotatably mounted on a machine base; b. a cradle of angular cross-sectional shape, in which an article to be cut may be rested, mounted on the machine base by means enabling elevational adjustment of the cradle to bring and hold the longitudinal axis of said article into substantial co-incidence with that of the fly-wheel; c. a first order lever eccentrically fulcrumed on the fly-wheel so that the lever may turn about its fulcrum in a plane normal to said fly-wheel axis; d. a knife on one end of said lever; e. a weight heavier than said knife on the other end of said lever; and f. drive means for rotating said fly-wheel.
Claim 5
Dependent Claim
146 words
A machine for cutting rod-like articles into required lengths, comprising: a. a fly-wheel rotatably mounted on a machine base; b. a cradle in which an article to be cut may be rested and held with its longitudinal axis substantially co-incident with that of the fly-wheel; c. a first order lever eccentrically fulcrumed on the fly-wheel so that the lever may turn about its fulcrum in a plane normal to said fly-wheel axis; d. a knife on one end of said lever; e. a weight heavier than said knife on the other end of said lever; f. drive means for rotating said fly-wheel; and g. a clamping plate pivotally mounted on the machine base and able to rest upon an article work-piece in said cradle, a handle pivoted on said clamping plate and spring means which resiliently oppose mutual approach of said clamping plate and said handle.
Claim 6
Dependent Claim
