Abstract
Abstract Apparatus for the continuous spinning of textile fibers by the open end spinning method, particularly by means of a spinning chamber operating under pressure. The separate spinning units of the apparatus are driven by a common drive from which they are separately disengageable. The spinning chamber of each spinning unit is mounted in a stationary body on the machine frame; the separating and feeding mechanisms of each spinning unit are mounted in a body which is generally movable away from the spinning chamber, whereby to improve the ease with which the spinning units may be attended and maintained.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
89 words
In an apparatus for the continuous spinning of textile fibers by the open end spinning method, said apparatus having a plurality of spinning units which are driven by a common drive means and which are individually disengageable from said drive means, the improved spinning units which comprise two bodies, one of which is stationary and the other of which is mounted for movement relative thereto between operative and inoperative positions, the outer end of the rotatably driven element being exposed when the movable body is in its inoperative position.
Claim 2
Dependent Claim
89 words
In an apparatus for the continuous spinning of textile fibers by the open end spinning method, said apparatus having a plurality of spinning units which are driven by a common drive means and which are individually disengageable from said drive means, the improved spinning units which comprise two bodies, one of which is stationary and the other of which is mounted for movement relative thereto between operative and inoperative positions, the outer end of the rotatably driven element being exposed when the movable body is in its inoperative position.
Claim 3
Dependent Claim
34 words
Apparatus according to claim 1, wherein the machine has a frame, each of the spinning units has a spinning chamber, and the spinning chamber is mounted in a stationary body on the machine frame.
Claim 4
Dependent Claim
41 words
Apparatus according to claim 1, wherein each of the spinning units has a separating mechanism and a feeding mechanism associated therewith, and the separating and feeding mechanisms of the spinning units are mounted in the movable one of the two bodies.
Claim 5
Dependent Claim
16 words
Apparatus according to claim 3, wherein the movable body is swingably mounted upon the stationary body.
Claim 6
Dependent Claim
82 words
Apparatus according to claim 1, wherein the spinning chambers are driven by a driving mechanism comprising a main driven shaft extending longitudinally of the apparatus, a driving disc on the main driven shaft in the vicinity of each of the spinning units, the spinning chambers being provided with driving pulleys, and a plurality of driving belts each of which is entrained over a respective one of the driving discs and over at least the driving pulleys of two oppositely disposed spinning chambers.
Claim 7
Dependent Claim
46 words
Apparatus according to claim 5, comprising two stationarily disposed guiding rollers and an adjustable resiliently biased tensioning roller positioned therebetween, the driving belt engaging the guiding and tensioning rollers between its engagement with the driving pulleys of the units on the opposite sides of the apparatus.
Claim 8
Dependent Claim
44 words
Apparatus according to claim 1, comprising means for selectively disengaging the driving belt from the driving pulley of each of the spinning units, said belt-disengaging means comprising a belt-disengaging roller which is interposable between the belt and the driving pulley for said spinning unit.
Claim 9
Dependent Claim
67 words
Apparatus as claimed in claim 7, wherein the belt disengaging roller is mounted upon an arm, and the arm is selectively moved in opposite directions by a control element, said control element being connected to the movable body of the spinning unit, whereby the belt is disengaged from the driving pulley of a spinning unit when the movable body of such unit is moved into inoperative position.
Claim 10
Dependent Claim
41 words
Apparatus according to claim 1, comprising driving means for the separating and feeding mechanisms, said driving means comprising two continuous shafts extending along each side of the apparatus above and below respectively the stationary body of each of the spinning units.
Claim 11
Dependent Claim
56 words
Apparatus according to claim 9, comprising driving trains extending between each of said two longitudinally extending shafts, and a driving train between the respective shafts and the separating mechanism and the feeding mechanism, said driving train being broken upon the moving of the movable body of a spinning unit from its operative to its inoperative position.
Claim 12
Dependent Claim
66 words
Apparatus according to claim 10, wheRein both driving trains include serially meshing gears, one gear in each train being journaled on an axis fixed with respect to its driving shaft, another gear, which normally meshes with said first gear, being journaled on the movable body so as to move out of mesh with the one gear when the movable body is moved toward its inoperative position.
Claim 13
Dependent Claim
80 words
Apparatus according to claim 9, wherein at least one of the driving means comprises a pulley on the respective shaft, a pulley on the respective shaft, a pulley journaled on the movable body, a belt entrained over such two pulleys, said belt having an excess length, and a resiliently biased belt-tensioning pulley which pulls the belt into a salient run, whereby the drive through the said driving means continues despite the moving of the movable body into its inoperative position.
