Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
186 words
Device for the slowing down of a mechanical step drive, especially for use in electric automatic cycle operations, in which an automatic cycle switch disc is provided, comprising a conveying latch spring biassed for axial movement in one direction, means for moving said latch to a predetermined extent for axial movement in another direction opposite said one direction, said latch cooperating with gear teeth provided on said disc for turning same during movement of said latch in said one direction, a flywheel mounted on a rod for rotation about the rod axis perpendicular to the movement of said latch, means on said rod in engagement with said latch for causing rotation of said flywheel in opposite directions during movement of said latch in said one and said another directions, respectively, whereby said flywheel serves to decrease the speed of the conveying movement of said latch as said flywheel changes its direction of rotation when said latch commences its axial movement in said one direction, thereby substantially preventing continued rotation of said disc beyond a predetermined conveying step as determined by said predetermined movement of said latch.
Claim 2
Dependent Claim
186 words
Device for the slowing down of a mechanical step drive, especially for use in electric automatic cycle operations, in which an automatic cycle switch disc is provided, comprising a conveying latch spring biassed for axial movement in one direction, means for moving said latch to a predetermined extent for axial movement in another direction opposite said one direction, said latch cooperating with gear teeth provided on said disc for turning same during movement of said latch in said one direction, a flywheel mounted on a rod for rotation about the rod axis perpendicular to the movement of said latch, means on said rod in engagement with said latch for causing rotation of said flywheel in opposite directions during movement of said latch in said one and said another directions, respectively, whereby said flywheel serves to decrease the speed of the conveying movement of said latch as said flywheel changes its direction of rotation when said latch commences its axial movement in said one direction, thereby substantially preventing continued rotation of said disc beyond a predetermined conveying step as determined by said predetermined movement of said latch.
Claim 3
Dependent Claim
27 words
The device according to claim 1 wherein a lock latch is provided for interengaging with said gear teeth thereby further preventing said continued rotation of said disc.
Claim 4
Dependent Claim
32 words
The device according to claim 1 wherein said latch is provided with ratchet teeth, and wherein said means on said rod comprises a gear wheel arranged to intermesh with said ratchet teeth.
Claim 5
Dependent Claim
40 words
The device according to claim 3 wherein said ratchet teeth are provided along a predetermined length of said latch and are so disposed therealong that, after completion of said conveying step, said ratchet teeth and said gear wheel become disengaged.
Claim 6
Dependent Claim
22 words
The device according to claim 4 wherein means are provided on said rod for pressing said gear wheel against said ratchet teeth.
