The invention has reference to ring spinning, doubling and twisting machines, both of the more usual kind in which the relative movement between the spindles and the rings which is necessary to bring about the desired formation of the packages of yarn or thread wound upon the spindles is obtained by raising and lowering the ring rails, the spindle rails being stationary, and of the kind incorporating stationary ring rails and rising and falling spindle rails. The object of the invention is to provide in either of such kinds of ring spinning or like machine an improved method of suspending and guiding the reciprocatory elements (i. e. either the ringrails or the spindle rails) and improved mechanism for transmitting to said reciprocatory elements the alternating rotary movement determined by the buildin motion.

According to this invention the reciprocatory elements at both sides of a ring spinningdoubling or twisting machine are connected across the machine by horizontal cross-members guided to follow a vertical path, constituting with said elements a frame capable of vertical reciprocatory movement, and said frame is suspended by chains or equivalent members suspended from and actuated by two inter-geared shafts one of which is driven by the building motion.

The said inter-geared shafts may be disposed in parallelism longitudinally of the machine, one

thereof being aligned with and coupled at one end to a shaft component of the driving mechanism associated with the building motion, the other shaft being geared with the first in such manner as to rotate in the opposite direction to members 3 and the outer casings. 4. Each of said from one shaft by two chains attached at either I end thereof.

The manner in which the invention may be carried into effect in a ring spinning frame having stationary ring rails and rising and falling spindle rails, is hereinafter more fully described with reference to the more or less diagrammatic illustrations contained in the accompanying drawings. Fig. 1 of said drawings is a plan of an embodiment of the invention incorporatin longitudinal shafts; Fig. 2 is a cross-section thereof taken on the line II-l'I of Fig. 1, and Fig. 3 is a fragmentary view in plan depicting a modifiedguiding arrangement for the reciprocatory frame. Figs. 4 and 5 are details illustrating two alternative inter-gearing arrangements for the longitudinal shafts,

Figs. 6 and 7 are respectively an elevation and a plan of a portion of a spinning frame embodying a modification of the invention.

The machines illustrated in the drawings are of a sectional unitary construction comprising a number of self-contained units erected end to end and each having at either extremity an endframe or spring-piece I to which are attached the stationary ring-rails 2, the longitudinal frame end-frames I is provided on its inner face with a vertical groove 5 extending along the centre-line of the end-frame; such groove 5 may conveniently be moulded in the casting of the frame I and subsequently machined to form a guide with truly parallel Walls.

' r The spindle-rails, denoted by the reference numerals {6, are connected together across the machine at each end by a cross-member 1 which carries on its outer face a block 8 arranged to slide in the adjacent groove 5, thereby ensuring that reciprocatory motion imparted to the frame constituted by the spindle rails 6 and the members l is constrained to follow a vertical line.

Mounted above the said frame in bearings 9, 9 etc. are two shafts l0 and II respectively, extending lengthwise of the sectional unit of the machine. The shaft Ill is connected at one end by a coupling [2 to a driving shaft I3 forming part of the building motion which is enclosed in the headstock casing l4, and at the other end by a short coupling shaft l5 to the shaft I 0 of the next machine unit. The shaft II is geared to the shaft [0 by two sets of identical spur wheels l6 and H, as shown in Figs. 1 and 2, or by spur wheels l8 and I9 with intergearing idler pinions 20 and 2|, as shown in Fig. 4, or by cross-connected chain-and-sprocket gearin as shown in Fig. 5.

Each shaft III, II carries a pair of sprockets 22, 22 over which driving chains 23, 23 are suspended to'support the spindle-rails 6 by means of the attachments 24, 24. The slack of each chain 23 is led under a jockey sprocket 25 at the base of the machine, an arrangement which ensures that the spindle rails 6 are moved positively in both upward and downward directions and avoids the possibility of their jamming or failing to fall at the proper speed as might occur if the positive drive were used only to raise the rails, and their return movement effected simply by gravity. A further advantage of this arrangement is that it enables the reciprocatory elements to be returned to the positions appropriate to dofiing and the subsequent resumption of the spinning operation.

In order to minimize the power required to raise the spindle-rails the mass of the combined reciprocatory elements (including the electric motor used to drive the spindles, where an independent motor is provided in each machine unit) is counter-balanced by balance weights 26, 26

slung by straps 27, over pulleys 28 fixed upon the shaft I I as shown. The mass of the reciprocatory structure 29, 29 carrying underslung bearing 5) brackets 30, 30 which support for each machine unit a pair of transverse shafts 3|, 3|. Each of said shafts has a sprocket 32 fixed thereon and engaging an endless driving chain 33 which extends throughout the length of the machine and y,

is suitably driven by the building motion enclosed in the headstock casing I4, the arrangement being such that every shaft 3| of each unit rotates in unison with the rest when actuated by said chain 33. At each end of each shaft 3| is a sprocket 34 over which is slung a chain 35 attached to the spindle-rail frame at 36. (Alternatively an endless chain, giving positive driving motion in both directions, such as that which has already been described with reference to Figs. 1 and 2 may be employed in lieu of the unidirectional chain drives shown in Figs. 6 and 7.)

Balance weights 31, 31 are suspended by chains 38, 38 slung over the sprockets 39, 39 on said shafts.

It will be evident that either of the two embodiments of the invention hereinbefore described with reference to Figs. 1 to 5 or Figs. 6 and 7, respectively, of the drawings is capable" of application without modification in principle to a machine in which the ring rails are the reciprocatory elements.

What I claim as my invention and desire to secure by Letter Patent is:

A ring spinning, doubling and twisting machine comprising thecombination of stationary ring rails, spring pieces, and reciprocating spindle rails, horizontal cross members connecting said spindle rails constituting with said spindle rails a frame, guide members for said cross members for guiding them to follow a vertical path so that said frame is capable of vertical reciprocatory movement, a plurality of intergeared shafts supported vertically above and within the area formed by said frame, means for driving one of said shafts from said power input means, flexible members fixedly attached to said frame suspended and actuated from said shafts for suspending said frame, whereby reciprocal rotary movement of said shafts produces reciprocative vertical motion of said frame.
