Abstract

Apparatus is disclosed for bringing into proximity and connecting a quench stack and monomer ring for the melt spinning of synthetic polymer fibers. These members are brought into proximity through use of a reel assembly and are connected by means of a clamping device. The clamp, which is mounted on the quench stack, features a drawpiece comprising a rod. The rod is curved into a "U" shape, the base of which engages with a keeper element and the legs of which describe a circle bend prior to terminating in a threaded shank for mounting to the clamp.

Claims

1. Apparatus for bringing into proximity and connecting a quench stack and the apparatus next upstream of said quench stack, comprising:

(A) a first keeper element, which is mounted on said upstream apparatus;

(B) a reel assembly, comprising;

(1) a reel which is biased to retract and which is mounted to said quench stack;

(2) a cable, which is engageable at one end to said first keeper element and which is fastened at its other end to and which retracts by means of said reel;

(C) a second keeper element, which is mounted on said upstream apparatus; and

(D) a toggle clamp, which is mounted on said quench stack and which comprises a drawpiece, said drawpiece comprising a rod which is curved into a "U" shape, the base of which engages with said second keeper element, each of the legs of said "U"-shaped rod describing a circle bend prior to terminating in a threaded shank for mounting to said clamp, said rod approximating a circle in cross-section, the ratio of the mean diameter of said circle bend to the diameter of said rod ranging from 3 to 5.

2. Apparatus for bringing into proximity and connecting a first member and a second member, one of said members being a quench stack and one of said members being the apparatus next upstream of said quench stack, each of said members forming individual chambers which when brought into proximity and connected form a larger chamber, said apparatus comprising:

(A) a first keeper element, which is to be mounted on one of said members;

(B) a reel assembly, comprising;

(1) a reel, which is biased to retract and which is to be mounted to the other of said members; and

(2) a cable, which is engageable at one end to said first keeper element and which is fastened at its other end to and which retracts by means of said reel;

(C) a second keeper element, which is to be mounted on one of said members; and

(D) a clamp, which is to be mounted on the other of said members and which comprises a drawpiece, said drawpiece comprising at least one leg, said leg being formed of a rod and having a catch at one end thereof, said leg terminating at its other end in means for mounting to said clamp, said leg describing a coil intermediate to its said ends, said catch being engagable with said second keeper element to connect said members when said members are brought into proximity by said cable retracting by means of said reel.

3. Apparatus for bringing into proximity for connection two members which together form a chamber, one of said members being a quench stack and one of said members being the apparatus next upstream of said quench stack, one of said members having mounted thereto a keeper element, said apparatus comprising:

(A) a reel, biased to retract and mounted to the other of said members; and

(B) a cable, connected at one end to said keeper element and fastened at its other end to and retracting by means of said reel;

whereby said members are brought into proximity for connection when said cable is urged to retract.

4. The apparatus of claim 3 wherein the apparatus next upstream of said quench stack is a monomer ring.
