Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
109 words
A stabilizing system for the oscillator plate of a multiple spindle drive head which includes a housing, means for mounting said oscillator plate in the housing for non-rotative circular translatory motion relative to the housing and surrounding space, and a drive crank for the oscillator plate, characterized by the provision of at least two parallel motion linkages connected to and supporting the oscillator plate in the housing, one at each of different sides of the oscillator plate, the driving connection between the drive crank and the oscillator plate being located at the center of the plate between the sides thereof and at the center of gravity of the plate.
Claim 2
Dependent Claim

A stabilizing system for the oscillator plate of a multiple spindle drive head which includes a housing, means for mounting said oscillator plate in the housing for non-rotative circular translatory motion relative to the housing and surrounding space, and a drive crank for the oscillator plate, characterized by the provision of at least two parallel motion linkages connected to and supporting the oscillator plate in the housing, one at each of different sides of the oscillator plate, the driving connection between the drive crank and the oscillator plate being located at the center of the plate between the sides thereof and at the center of gravity of the plate.
Claim 3
Dependent Claim
148 words
A gearless multiple spindle drive head including a housing, a drive crank, an oscillator plate driven by the drive crank, means mounting the oscillator plate in the housing for non-rotative circular translatory motion relative to the housing and surrounding space, the radii of the circular paths of translation of points on the oscillator plate being the same as the throw radius of the drive crank, the oscillator plate being adapted to drivingly engage a plurality of driven cranks each having the same throw as the drive crank, characterized by the provision of at least two parallel-motion linkages connected to and supporting the oscillator plate in the housing, one at each different sides of the oscillator plate, the driving connection between the drive crank and the oscillator plate being located at the center of the plate between the sides thereof and at the center of gravity of the plate.
