Abstract
Abstract A spinning frame having spindles comprising a fixed part for the admission of slivers, and a rotary spinning bowl part, is so arranged that the bowl can be belt driven at relatively high speeds, and the two parts can be pivoted apart for inspection or cleaning, without handling of driving belts, and so that the drive is automatically disengaged.

Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
244 words
A spinning machine having a frame and spindles carried by the frame, each spindle comprising a fixed part and a rotary part a rod carried by the frame and located at right angles to the axis of the fixed part of the spindle, an arm having opposite ends, said rotary part being freely rotatable on one end of the arm, the other end of the arm being pivotable on the rod in such manner as selectively to occupy either a working position in which the rotary part of the spindle coacts with the fixed part, or an inspection position in which the rotary part of the spindle is disengaged from the fixed part, releasable locking means cooperable with the fixed part and the movable part to maintain said parts in the working position, a rotary drive for the spindle said drive including a small pulley secured to the rotary part, a shaft carried by the arm adjacent the rod and extending perpendicularly to the arm, a large pulley freely rotatable on said shaft, a third pulley of lesser diameter integral with the large pulley, a friction-driving belt parallel to said rod trained about said third pulley; so that, when said arm is in its inspection position, the third pulley is disengaged from the friction belt, and, when the arm is in the working position, the third pulley engages the friction belt and an endless belt passing around the small pulley and the large pulley.
Claim 2
Dependent Claim
244 words
A spinning machine having a frame and spindles carried by the frame, each spindle comprising a fixed part and a rotary part a rod carried by the frame and located at right angles to the axis of the fixed part of the spindle, an arm having opposite ends, said rotary part being freely rotatable on one end of the arm, the other end of the arm being pivotable on the rod in such manner as selectively to occupy either a working position in which the rotary part of the spindle coacts with the fixed part, or an inspection position in which the rotary part of the spindle is disengaged from the fixed part, releasable locking means cooperable with the fixed part and the movable part to maintain said parts in the working position, a rotary drive for the spindle said drive including a small pulley secured to the rotary part, a shaft carried by the arm adjacent the rod and extending perpendicularly to the arm, a large pulley freely rotatable on said shaft, a third pulley of lesser diameter integral with the large pulley, a friction-driving belt parallel to said rod trained about said third pulley; so that, when said arm is in its inspection position, the third pulley is disengaged from the friction belt, and, when the arm is in the working position, the third pulley engages the friction belt and an endless belt passing around the small pulley and the large pulley.
Claim 3
Dependent Claim
27 words
The frame in accordance with claim 1, including a brake shoe with which the third pulley is in contact when said arm is in the inspection position.
Claim 4
Dependent Claim
43 words
The frame in accordance with claim 1, in which said other end of said arm is in the form of a two-armed spring clip gripping said rod in such a manner as to form a releasable connection between the arm and the rod.
Claim 5
Dependent Claim
39 words
The frame in accordance with claim 1, in which the spindle is on a vertical axis, with said rod and the friction belt being horizontal and the rotary part of the spindle being arranged below the fixed part thereof.
Claim 6
Dependent Claim
41 words
The frame in accordance with claim 1, in which the spindle has a nozzle for the admission of the fibers, a socket in the fixed part in which said nozzle is fitted, and quick release and attaching means for the nozzle.
Claim 7
Dependent Claim
47 words
The frame in accordance with claim 5, in which the admission nozzle is removable in the direction of the rotary part when the arm is in the inspection position, and spring catches holding the nozzle in place in said socket constituting the quick release and attaching means.
Claim 8
Dependent Claim
189 words
In a spinning machine having frame means, and at least one spinning unit comprising stationary spinning means carried by the frame means and rotary spinning means including a first pulley and a spinning chamber mounted on the first pulley for rotation therewith, a rod supported by said frame means, an arm having opposite ends, one end of said arm being connected to said rod for swinging movement relative to the stationary spinning means, said first pulley being mounted on said arm for swinging movement therewith between an operative position in which said chamber cooperates with said stationary spinning means to spin a yarn and an inspection position in which said chamber is spaced from said stationary spinning means, a second pulley mounted on said arm so as to lie between the first pulley and said rod, said second pulley having two cylindrical length portions of different diameter, a friction drive belt engaged by the smaller diameter portion of said second pulley only when said chamber is in its operative position, and a drive transmission belt trained over said first pulley and the larger diameter portion of said second pulley.
Claim 9
Dependent Claim
189 words
In a spinning machine having frame means, and at least one spinning unit comprising stationary spinning means carried by the frame means and rotary spinning means including a first pulley and a spinning chamber mounted on the first pulley for rotation therewith, a rod supported by said frame means, an arm having opposite ends, one end of said arm being connected to said rod for swinging movement relative to the stationary spinning means, said first pulley being mounted on said arm for swinging movement therewith between an operative position in which said chamber cooperates with said stationary spinning means to spin a yarn and an inspection position in which said chamber is spaced from said stationary spinning means, a second pulley mounted on said arm so as to lie between the first pulley and said rod, said second pulley having two cylindrical length portions of different diameter, a friction drive belt engaged by the smaller diameter portion of said second pulley only when said chamber is in its operative position, and a drive transmission belt trained over said first pulley and the larger diameter portion of said second pulley.
Claim 10
Dependent Claim
38 words
The spinning machine according to claim 7, further including fixed brake means positioned on said frame means to be engaged by said smaller diameter portion of the second pulley when the spinning chamber is in the inspection position.
