AND APPARATUS FOR WASHING ARTIFICIAL SILK.

Application filed April 26, 1923. Serial No. 634,867.

To all whom it may concern: Be it known that I, ADRIEN PINEL, a citizen of the French Republic, residing at Rouen, in the Department of Seine-Infel rieure and'State of France, have invented or discovered certain new and useful Improvements in Processes and Apparatus for Washing Artificial Silk, of which the following is a s ecification, reference being had therein to tile accompanying drawings. a It is known that bobbins of artificial silk as they leave the squirting and coagulating apparatus have' to be washed and dried.

This washing is necessary for the reason that the cellulose from which the artificial silk is made is impregnated with certain acids and salts which will change the same, both chemicall and physically, when the silk is dried, irnot eliminated.

These two operations such as hithertok-arried out, take considerable time. There is, therefore, a considerable accumulation of materials and of bobbins being treated; and an excessive delay'in the manufacture.

As to the drying, it is possible; to reduce its duration by a reliminary drying of the bobbins by centrif il tage however is to a great extent neutralized by the time and the supplementary opera 30 tions which are necessary for placing in and Withdrawingthe bobbins from the centrifugal drying machine and by the waste which often results therefrom.

The present invention has for its object a rapid and economic Washing of bobbinsof artificial silk which leave thesquirting and coagulating apparatus andat the same time placing them under such conditions that their subsequent drying shall be also more rapid and consequently, more economic:

' To this end, the invention has for its object, amethod of rapid and economic washing of bobbins of artificial silk consisting in principle, in the combinationof successive alternating washings and centrifugal dryings, each being of a comparatively shortv duration, it being possible to vary this method in any suit-able manner and morepartic ularly with a view to'increasing the economic character, by means of a new type of washing and centrifugal drying machines, which is also within the present invention.

The above process may be carried into practice in various ways, among others and by way of example, the bobbins to be washed gal action. This advanmay be sprayed during a few minutes, then they may be subjected to a centrifugal drying also for a few minutes and these two operations may be alternately repeated, thus obtaining a perfect washing after about one hour of this treatment, the last centrifugal drying operation expelling the liquid which impregnates the bobbins, putting the latter in favourable conditions for a subsequent rapid and economic drying.

The duration of the alternating periods ofwashing and centrifugal drying may be equal or not for each of the operations, they may be increasing or decreasing, and also the duration between each period of washing and centrifugal drying necessary for carrying them out, may constitute a third phase of the process, the duration of which may then be prolonged and become equal or longer or shorter than the duration of the periods of washing and centrifugal drying, the said third period permitting the impregnation of the bobbins sprayed'with a small quantity of water and consequently increasing'the economy of the process, by reducing the consumption of the washing water.

For carrying the above said principles of the invention into practice, various means may be used, either manual or mechanical; the washing may be effected byv spraying, immersion, or circulation, and. the drying by means of any centrifugal dryin machines; however, in order to do away with any useless, harmful and costly handling of the bobbins, it will be preferable to carry out the process by means of a newtype of washing and centrifugal drying machine, permitting the washing and centrifugal drying of the bobbins without handling them, according to the chosen mode of carrying the in vention into effect. A machine of this kind may, for instance, be constructed and operated as hereinafter described and diagrammatically illustrated by way of example in the drawings accompanying the present description and in which: Fig. .1 is a front elevation. Fig. 2 is a diametral vertical section.

Referring to the drawings, 1 is a frame in 05' which is journalled a horizontal driving shaft 2 to one end of which is fixed a circular carrier 3 from one or both of the faces 1 of which, and near its peripher extend one, two or a larger number 0 circular series of bobbin-holders, each consisting a leys which may be connected by a belt 10 with fast and loose pulleys on the shaft 12.

"The motor shaft has a suitable connection,

preferably of a pair of spindles 4 on which are placed the bobbins 5. In order to maintain the bobbins 5 upon their bobbin-holders 4, during the working of the machine, one of the holders 4 of each pair is provided at its outer end with a small oscillating or rotary projection 6, which allows or prevents, according to its position, the withdrawal or insertion of the bobbins 5. The said projection may, of course, be replaced by any other means for holding the bobbins 5 on the spindles 4. y

A water distribution pipe system 7 is-arranged outside of the whole or a part of the periphery of the rotary carrier 3, and compises cross pipes having perforations 8 which are suitablejin number and are prop erly located to spray the bobbins 5, mounted upon the bobbin-holders 4, with jets of water, either during a continuous, but slow, or an intermittent rotation of the member 3. To this end, the actuation ofthe bobbin carrier 3, by the shaft 2; will be such, that it will be possible to obtain, at will, either a very high speed of rotation of said carrier, with a view to drying by centrifugal .action, or a slower speed of rotation permitting the spraying; or a very high speed for drying by centrifugal action, and a stoppage for spraying, these combinations being capable of being carried into efi'ectby various driving means. Such operations may be effected by the means of an electric motor 9 having a shaft provided with fast and loose pulshown in dotted lines in Fig.2, with a shaft which is provided with a worm 12 meshing with a worm-wheel 13 near the lower'end of a vertical shaft 11 which is provided near its upper end with a worm meshing with a worm-wheel 14 on the shaft 2. This connection between the motor shaft and the shaft carrying the worm 12 is preferably effected by a pawl which is automatically lifted when the shaft 2 is driven at a high speed by the belt 10 running from a pulley on the shaft of the motor 91 When it is desired to rotate the bobbin-carrier 3 slowly for a washing operation the shaft 2 will be rotated by means of the worm and worm-wheel gearing just described, the belt 10 being at such time shifted to the loose pulleysreferred to; but when it is desired to rotate the bobbin-carrier 3 rapidly, for

centrifugal drying, the worm and wormwheel gearing will be disconnected from the motor shaft and the belt 10 will be shifted to the loose pulleys on the motor shaft and the shaft 2. Either the slow or rapid rotations of the bobbin-carrier 3 may be effected intermittingly by an intermittent energizing of the electric motor 9, by turning the current ofi and on, as will be obvious.

A casing, not illustrated, will, in practice, enclose the bobbin-carrier 3 and its spraying system, with a view to avoiding the splash ing of liquid which is collected and removed for treatment, if desired, with a View to the recovery of the substances which have been carried off by the washing operation.

With this machine or" with any other machine of the same type, constructed or adapted in such a manner as to allow the present process of being carried into effect, according to the above principle, the bobbins to be washed may be treated rapidly and economically, after the bobbins 5 have been mounted u on their holders or supports 4.-

The bob in-carrier 3 is caused to rotate.

very slowly for a few minutes during which the spraying water is projected through the jets 8, uponthe bobbins; afterwards, the, delivery of water being stopped, the carrier is caused to rotate rapidly, in such a manner as to effect the centrifugal drying of the bobbins which have just been washed.

After a few minutes of centrifugal drying, the rapid rotation of the carrier 3 is drying taking lace afterwards, and so on,

the saving in liquidbeing thereby still further effected and also the ex 'ense in the motive power, the duration of t e treatment being about the same as previously.

In certain cases, the washing may take place with the bobbin-carrier 3 stopped, the

spraying being replaced by a temporary im-.

mersion in water of the whole or part of the bobbins mounted upon the carrier which may be disposed horizontally or vertically, all these variations in the carrying out of the rapid and economic method of washing, ac-

cording to the present invention, being within the principle of the invention.
