Specification of Letters Patent.

Patented Aug. 8, 1905.

Application filed April 4:, 1905. Serial No. 253,802.

To all] whom it may concern:

Be it known that I, RUDoLF LINKMEYER, engineer, a subject of the German Emperor, residing at Brussels, Belgium, have invented a new and useful Improvement in Devices for the Manufacture of Artificial Silk Threads,

and I do hereby declare the following to be a full, clear, and exact description of the same.

My present invention relates to the manufacture of artificial silk, the object being to provide an improved device for the manufacture of silk threads, and more particularly for the reception of artificial threads. Heretofore many devices of this class have been constructed; but in almost all of them the artificial threads are spooled upon glass cylinders. This operation may be effected very easily; but the threads cannot be unrolled from said cylinders in an easy and ready way. The old method produces, moreover, a large amount of waste, and as only a relatively small amount of silk can be spooled upon a glass cylinder the transportation of the product becomes very expensive. These and other objections are completely avoided by my present invention, which consists in the construction, arrangement, and combination of parts fully described and claimed hereinafter, reference being had to the accompanying drawings.

Figure 1 is a diagrammatical elevation of the improved device, and Fig. 2 illustrates the way in which the thread is deposited.

1 represents the reservoir wherein the solution of cellulose is discharged through minute nozzles and converted into primary threads. The latter are taken from said reservoir and passed through forks 2 over a roller 3, made of glass and rotated by means of any suitable transmission device, so that the threads are continuously pulled thereby out from said reservoir 1. From said roller 3 each thread arrives downwardly into a spinning-pot 4, preferably made of glassor similar material, into which the thread is deposited in a particular way. To this end the pot or receptacle 4 is placed upon -a pan-like disk 6, arranged on a vertical shaft 5, provided at its lower end with a drive-disk 7, frictionally engaged by the roller or pulley 13, keyed on a suitable motor-shaft. The shaft 5 is journaled in bearings 8 8, the lower one of which is made one with a laterally-extending bar 9, adapted to be oscillated in a horizontal plane by the agency of a cam 10 or the like. The bearings 8 are arranged at the ends of horizontal bars 11, connected by means of a vertical shaft journaled in a suitable bearing 12.

It will be seen that in my improved arrangement the spinning-receptacle 4. is rotated and simultaneously oscillated or reciprocated, so that the thread coming from the roller 3 is deposited in uniform crossing layers and cannot be entangled. (See Fig. 2.) This particular deposition of the thread is an essential feature for the subsequent treatment of the artificial silk.

When the receptacle 4 contains a sufficient amount of thread, it is removed from the disk 6 and another similar receptacle is substituted therefor.

The rotary and reciprocating movement may be imparted to the receptacle 4 inany suitable and convenient manner, and I wish it to be understood that I do not limit my invention to the particular form of embodiment shown in the accompanying drawings.

Having fully described my invention,what I claim, and desire to secure by Letters Pat ent, is

1. In a device of the class described, the combination with the reservoir wherein the primary silk threads are formed, of forks for gathering up said threads by series, a rotatable roller arranged in close proximity to said forks, a receptacle arranged below said roller to receive the silk thread as it comes from the roller, and means for simultaneously imparting rotary and reciprocating movements to said receptacle, substantially as set forth.

2. In a device of the class described, the combination with the reservoir wherein the primary silk threads are formed, of forks for gatherin up said threads by series, a rotatable rol er arranged in close proximity to said forks, a receptacle arranged below said roller to receive the silk thread as it comes from the roller, a horizontal plate or disk adapted to receive said receptacle, a vertical shaft carrying said disk, suitable bearings for said shaft, means for rotatin said shaft, and means for imparting an oscil ating or reciprocating movement to said bearings, substantially as set forth.

3. In a device of the class described, the combination with the reservoir wherein the primary silk threads are formed, of forks for gathering up said threads by series, a rotatable roller arranged in close proximity to said forks, a receptacle arranged below said roller to receive the silk thread as it comes from the roller, a vertically-arranged shaft, means carried by said shaft for receiving'and hold-' ing said receptacle, bearings for said shaft, a suitable friction transmission for rotating the same, a pivotal connection between said ing said receptacle, bearings for said shaft, a suitable friction transmission for rotating the same, a pivotal connection between said bearings, a laterally-extending bar made one with one of said bearings, a transmission shaft, and a suitable cam on the same arranged to engage the end of said bar for irnparting. an oscillating or reciprocating movement to said bearings, substantially as set forth.

In testimony whereof I have signed my name to this specification in the presence of two. subscribing witnesses.
