SEBASTIAN ZIANI DE FERRANTI, OF LONDON, ENGLAND- TURBINE-DRIVENSPINNING, DOUBLING, AND TWISTING MACHINE.

`Speorlcation of Letters Patent.

Patented Aug. 1o, 1909.

Application filed August 13, 1906. Serial No. 330,471.

have invented certain new and useful Improveniente Relating toA Turbine-Briven Spinning, Doubling, and Twisting Machines, of which the following is a specification.`

This invention relates to improvements in turbine driven spinning doubling and twisting machines. Y In the specifications of my patent applications, Serial Nos. 221,295, 260,120 and 272,- 560, I have described certain improvements in textile processes and in theconstructions` of apparatus having for their main object the obtaining of much higher rates of pro-v duction than are now common in textile work.

rFlic present invention Yhas for'its object to provide an improved` construction of machine for obtaining suchV high rates `of production. A

My improvements consist intim-following elements. In a twisting spinning or doubling machine, the twisting elements of which are turbine driven, considerable expense and crnnplication of parts is entailed if the turbine elements are connected to the pressure :nain by pipes in the ordinary manner. According to my lirst improvement, however, noty only is the expense materially reduced, but connecting pipes are entirely dispensed with by inserting the turbine elements into the longitudinal supply trunk; and in those circumstances in which the turbines do not exhaust directly into the atmosphereby so disposing' the exhaust trunk` that the turbine exhaust is discharged directly thereto while the arrangement of parts may preferably be sucn that the trunk or trunks form one of the main structural elements of the machine.

In the oaeration of hioh s eed turbine to effect a substantial reduction in such losses by constructing the-nozzles and casings so "that the blades are as completely shielded as possible, thereby preventing absorption of power by setting air in motion.

Referring now to the accompanying drawings which illustrate my invention and form part of' myspecitication; VFigure l shows a `cross sectional elevation of a machine constructed according to my invention, Fig. 2 shows an elevation and Fig. 3 a plan of the machine illustrated in Fig. l. Fig. Ll shows a detail of a modified form of working fluid trunk to that shown in Fig. l. Fig. 4a showsV cross sectional elevation of a form of machine in which the exhaust from the twisting elements takes place directly to the atmosphere.- Fig. 4b shows a detail view of the vfeed rolls shown in Fig. l. Fig.` 5 is a sectional elevation of one form of ring flier suitable for the twisting machines illustrated in Figs. l, 2, Fig. @shows outside elevation to a reduced scale ofthe ring fliers as shown in Fig. 5. Fig. 7 is a cross sectional elevation and Fig. Sis an inverted plan illustrating one method of reversing the ring flierV shown in Fig. 5. Fig. 9 is a detail view of a turbine bladed member provided with a shielding ring.

In carrying my invention into effect according to one modiication ns applied to the construction of a spinning twisting or doubling machine having leading and lag-V ging parts, I provide a central trunk, c, Figs. l, 2, and 3, which is divided longitudinally by a partition, Z), so as to form two distinct chambers one of which, o, supplies the working fluid to the turbines of the twisting elements, while the other d, leads away the exhaust therefrom. The partition, b, may be formed integrally with the trunk, a, as illustrated in Fig. 4l, or may be assembled therewith in the manner illustrated in Figs. l, 2 and 3. In the latter case the supply chamber, o, and exhaust chambers, d, are formed separately from the partition plate, o, the three parts being assembled in the manner indicated, studs, o, being inserted at intervals along the chamber, o, so as to form supports'for the plate, o. On each side of the trunks, holes, f, are formed into which the cylindrical casings, g, of the twisting elements are inserted. The twisting element in this case may preferably be an air borne turbine driven ring flier such as I have illustrated in Figs. 5 and 6 and will be hereinafter described.

. poses.

In order to prevent any leakage of the working fluid around the parts adjacent to the ring flier casing, g, I cause grooves, h, Figs. 5 and 6, to be formed Vat such places into which grooves one or more rings, z', of elastic packing are inserted. This arrangement not only i provides an exceedingly effective joint but also forms a flexible support for the twisting element and at the same time permits of the ready withdrawal of the element for inspection or other puri In some cases, however, Fig. la I may arrange for only one chamber in the trunk a for supplying the working fluid and allow the exhaust from the turbines to take place directly to the atmosphere.

In the above machines I find it preferable to construct a trunk in sections provided with connecting flanges so that a machine of any required number of spindles can be expeditiously and conveniently assembled by connecting together a suitable number of sections. Standards, j, for supporting the vtrunk are provided at intervals along the length thereof, one or more of which may conveniently be used for conducting the working fluid to the supply and two of them may be used for leading the air away from 'the exhaust chamber. The standard which is used for supplying the air is fitted with a valve for controlling the operation of the machine. A shaft, is, is rotatably mounted on thestandards j, and driven independently of the twisting elements, by a motor, Z, in an oscillatory manner so as to give the required reciprocating motion to the bobbin rail, m. This motion is obtained by mounting on the motor shaft, n, a heart shaped cam, 0, which actuates a roller, p, attached to an arm, q, and to a fixed center, r, by the links, 8 and t, respectively. The arm, Q, is rigidly fixed to the shaft, c, so that the rotation of the heart shaped cam gives an oscillatory or rocking motion of the shaft, 7c. Quadrants, u, are mounted on each end of the shaft and are attached by flexible chains, w, to the rods, o,

fixed to the bobbin rails, m, the motion of the bobbin rails being guided by sockets, m, in which the rods, o, slide.

Feed rolls, 5 one of which is resiliently mounted in the spring, 29 Fig. 4th, are disposed in a trough, y, formed integrally with the exhaust chamber and are driven from the lagging part in the manner described in my patent applications 26012() and 272560 by means of telescopic spindles, e, which pass through tubes, l, inserted in the working fluid trunk in an air tight manner. The material to be twisted is disposed in holders,

Ypreferably situated at the ends of the frame,

2', attached to standards, 3, and is led to the feed rolls, 5, through guide eyes, 4, which are 'attached to a rotatably mounted shaft, 6, extending the whole length of the machine so that the feed may be varied in all the individual units simultaneously in a manner which I have described in the specifications above referred to. After leaving the feed rolls the material passes over a guide rod, 7, through the guide eye, 8, to the winding hooks, 28, on the ring flier by which it is wound on the bobbin, t), mounted on a lagging tube preferably of the airborne type. It will be evident that this construction produces a machine of exceedingly compact form while the working fluid trunk forms one the main structural elements of the machine.

I will now describe a form of air-borne turbine driven ring flier suitable for insertion in the working fluid trunks and which is provided with ruiming bearing parts and ineans for reversing` the direction of rotation. which ring flier however forms no part of the invent-ion claimed herein.

Referring to Figs. 5 and G, the ring flier, l2, carries turbine blades, l0, of the Laval or other suitable type at its lower extremity the working fluid being led to the blades from the fluid supply trunk, c, by nozzles, 13, sets of which may be provided for either directions of rotation. The length of the nozzles, as shown is considerably shortened owing to Vthe manner in which they are cut by the sectio-nal plane. The ring of blades i0 is retained in position by a ring, l0, which is provided with winding hooks and is atiached to the flier, 1Q, by means of a bayonet joint or other suitable means. The turbine blades, it), are shielded by a ring or casing, Il, which, however, has a suflicient number of openings formed therein in adacent positions to discharge from the nozzles` so as to allow a free path for the exhaust. The ring, ll, is formed integrally with the part, lo, and incloses the turbine blades, 10, as much as possible in order to reduce the losses due to the fanning action of the blades. The casing, g, is formed in two i ,iria as shown and has projections, lef, attached to its inner surface so as to form an annular chamber, i5, between the casing, g, and the stationary part, It?. `Between the stationary part, i6, and the highest speed rotating part, 12, which constitutes the ring flier, running bearing parts, I7 and 1S are disposed having flanges, 19 and 20, which rest on au angled seat formed on the casing, g. The part, l2, is also provided with a flange, Q1, which is arranged above the flanges, lf) and 20. The exhaust from the turbine passes through the chamber, l5, lifts and supports the flanges, I9 and 20, and is thereby introduced below the flange, QI, upon which it acts in a similar manner and finally escapes to the exhaust chamber, (l, by the ducts, 22, and the holes, 23. It will thus be seen that the dead weight of the rotating parts is supported on a cushion of elastic fluid. Enlarged clearance spaces, 24, are provided in the running parts and the bottom of the parts, 16, 17 and 18, as well as the shielding ring, 11, are cut away as shown so as to allow a free path for the exhaust. The ring Hier, 12, is provided with winding hooks, 28, at both ends inv order to prevent fouling of the material.

ln order to economize space as much as possible the outside of the casing is flattened at the point, 25, whereit adjoins the adjacrut casings, the section at other points being as indicated by the dotted lines at 26. Between the ianges, 19, 20 and 21, cushions, 27, of rubber or other suitable material are inserted which act as bulfers and allow the ianges, 1S), 20 and 21 to be lifted silentl and together.

ln the above construction of ring flier I effect reversing by removing the ring yflier from its casing, inverting the bladed ring and then returning the flier toits casing. Sets of opposite handed nozzles, 13, il 7 and 8, are required in this case and a blanking valve or washer, 30, having a rubber face, 31, is disposed atthe entrance of the nozzles which washer is arranged to be rotated so as to cover the set of nozzles which it is desired to render inoperative.

1t will be obvious that the above device is of exceedingly simple construction and one in which the tanning losses occurring in the case where opposite sets of blades are provided for each direction of rotation are eliminated. i v p A i The amount of diametrical clearance between the various running bearing parts :should bc of 'the order for air bearings which i have stated in my patent applications Nos. 26u12() and 272560, in which specifications will also be found certain precautions which ought to be taken with regard to the condition of the air in order to obtain the best results.

l't will be obvious that my inventionvis not limited to a machine of the leading and lagging part type as with slight modification it could be applied to other types for example a cup or cylinder spinner and the example illustrated shows one `typical method of carrying my invention into effect.

1n turbine driven spinning twisting or doubling machines using an elastic working Yluid for actuating thetwisting elements of the machines, the turbines may be of any of the well known types, according` tothe second part of my invention however 1 construct the nozzles and casings so that 1 have the blades of the turbines as completely shielded as possible thus preventing them setting air in ino-tion and so absorbing power. For this purpose the turbine blades, 10, Fig. 9 rotate inside a smooth and closely fitting casing, 11, which has only sutlicient openings therein to efficiently discharge the exhaust. l prefer also to form the nozzles closely adjoining each other so that the eX- haust may be all discharged as nearly as possible in a solid jet, and also arrange the speed of the blades to that of the jet so that the velocity thereof y,is as fully utilized as possible. rlhis l am enabled to do by using low 'pressure air with nozzles which converge to the throat and either contract or do not substantially expand from the throat t0 their discharge orifices. The range of fall of pressure is only small.
