Abstract
A suspension assembly (A) for raising and lowering the ring rails (14, 14') of a textile yarn processing machine is disclosed. Vertical guide posts (18, 18') are disposed adjacent to each of the ring rails for guiding the ring rails as they reciprocate vertically. The opposed ring rails are connected by the suspension assembly which includes a parallelogram linkage comprised of a tension rod (24) pivotally connected to opposing bearing brackets (B, C) and a compression rod (26) which is pivotally connected to the opposing bearing brackets. Slide bearings (20, 20' and 22, 22') are carried by the bearing brackets (B, C) for bearing against the guide posts (18, 18'). The lengths of the compression rod and the tension rod are adjusted to bring the spaced slide bearings into light contact with an associated guide post so that the ring rails may be lifted by a lifter mechanism in unison without causing loads on the guide posts. If loads (D, E) on the ring rails are generally equal, the parallelogram suspension assembly will cancel any loads on the guide posts. Only the difference between the loads will be exerted on the guide posts.
