Abstract
Abstract In apparatus for cutting wire into lengths, the mechanical transmission between a drive and wire cutting means intermittently operable thereby includes an elastically deformable torsion rod having one end fixedly connected to the drive for rotation thereby and its other end connected to locking means operable to prevent rotation of the other torsion rod end whereby the torsion rod is subjected to torsion when the locking means is operated. Means for intermittently freeing the locking means permits rotation of the other torsion rod end.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
152 words
In an apparatus for cutting a flexible elongated element into lengths, which comprises a cutting mechanism including intermittently operable cutting means, means for continuously feeding the flexible elongated element to the cutting means, a drive for operating the cutting means, and a mechanical transmission between the drive and the cutting means, the mechanical transmission including 1. an elongated rotatable element elastically deformable under torsion and having two ends, a. one of the ends of the rotatable element being fixedly connected to the drive for rotation thereby, 2. a locking means connected to the other end of the rotatable element and operable to prevent rotation of the other end thereof while the one end is rotated by the drive whereby the rotatable element is subjected to torsion when the locking means is operated, and 3. means for intermittently releasing the locking means to permit rOtation of the other end of the rotatable element.
Claim 2
Dependent Claim
152 words
In an apparatus for cutting a flexible elongated element into lengths, which comprises a cutting mechanism including intermittently operable cutting means, means for continuously feeding the flexible elongated element to the cutting means, a drive for operating the cutting means, and a mechanical transmission between the drive and the cutting means, the mechanical transmission including 1. an elongated rotatable element elastically deformable under torsion and having two ends, a. one of the ends of the rotatable element being fixedly connected to the drive for rotation thereby, 2. a locking means connected to the other end of the rotatable element and operable to prevent rotation of the other end thereof while the one end is rotated by the drive whereby the rotatable element is subjected to torsion when the locking means is operated, and 3. means for intermittently releasing the locking means to permit rOtation of the other end of the rotatable element.
Claim 3
Dependent Claim
46 words
a locking means connected to the other end of the rotatable element and operable to prevent rotation of the other end thereof while the one end is rotated by the drive whereby the rotatable element is subjected to torsion when the locking means is operated, and
Claim 4
Dependent Claim
46 words
a locking means connected to the other end of the rotatable element and operable to prevent rotation of the other end thereof while the one end is rotated by the drive whereby the rotatable element is subjected to torsion when the locking means is operated, and
Claim 5
Dependent Claim
45 words
In the apparatus of claim 1, a drive shaft connected to the drive and an intermediate shaft connected to the cutting means, the rotatable element being fixedly connected at the one end to the drive shaft and at the other end to the intermediate shaft.
Claim 6
Dependent Claim
56 words
In the apparatus of claim 2, a disc eccentrically mounted on, and keyed to, the intermediate shaft, a circular ring wherein the eccentrically mounted disc is freely rotatably guided, a push rod extending radially from the circular ring, and an actuating mechanism for the cutting means, the push rod being mechanically connected to the actuating mechanism.
Claim 7
Dependent Claim
18 words
means for intermittently releasing the locking means to permit rOtation of the other end of the rotatable element.
Claim 8
Dependent Claim
18 words
means for intermittently releasing the locking means to permit rOtation of the other end of the rotatable element.
Claim 9
Dependent Claim
74 words
In the apparatus of claim 1, a drive shaft connected to the drive, a hollow shaft having two ends and an axial bore through which the elongated rotatable element extends, the one end of the rotatable element and one of the hollow shaft ends being fixedly connected to the drive shaft for rotation therewith, and the other end of the hollow shaft carrying a control for the means for intermittently releasing the locking means.
Claim 10
Dependent Claim
55 words
In the apparatus of claim 1, an intermediate shaft connected to the other end of the rotatable element and to the cutting means, and the locking means comprising a control disc mounted on the intermediate shaft for rotation therewith, and means operable to engage the disc for stopping rotation thereof and of the intermediate shaft.
Claim 11
Dependent Claim
118 words
In the apparatus of claim 5, a drive shaft connected to the drive, a hollow shaft having two ends and an axial bore through which the elongated rotatable element extends, the one end of the rotatable element and one of the hollow shaft ends being fixedly connected to the drive shaft for rotation therewith, the other end of the hollow shaft being freely rotatably journaled on the intermediate shaft, the means operable to engage the control disc comprising a stop on the disc and a stopping rod for engagement with the stop, and the means for intermittently releasing the locking means comprising cam means carried on the other hollow shaft end for disengaging the rod from the stop.
Claim 12
Dependent Claim
15 words
In the apparatus of claim 1, wherein the elongated rotatable element is a torsion rod.
Claim 13
Dependent Claim
17 words
In the apparatus of claim 7, wherein the torsion rod consists of an elastically deformable synthetic resin.
Claim 14
Dependent Claim
30 words
In the apparatus of claim 1, a drive for operating the continuous feeding means, and the drives for operating the feeding and cutting means being coupled for movement in unison.
Claim 15
Dependent Claim
52 words
