SWIFT FOR SILK-WINDING.

SPECIFICATION forming part of Letters Patent No. 417,424, dated December 1'7, 1889.

Application filed August 20, 1889.

To all whom it may concern:

Be it known that we, WILLIAM F. HOCH- SPEIER and LoUIs P. HOCI-ISPEIER, of Union Hill, in the county of Hudson and State of New Jersey, have invented a new and Improved Swift for Silk-Winding, of which the following is a full, clear, and exact description.

This invention relates to swifts for silkwinding, and has for its object to provide a swift by means of which the skein" thereon will be kept spread out and held in a steady position, can be readily and quickly loosened thereon, and can be beaten on the swift to spread the silk and prevent it from catching.

The invention consists of a swift constructed as hereinafter describedand claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar figures of reference indicate corresponding parts in all the views.

Figure 1 is a side view of aswift constructed in accordance with this invention. Fig. 2 is an end view of the swift, partly in vertical section; and Fig. 3 is adetail view, partly in section, onthe line ac 00, Fig. 2.

Heretofore in the swifts employed in silkwinding wires or cords have been employed with the rigid arms of the swift, over which cords the skein extended. The cords were shifted on the arms of the swift to adjust the skein by slipping them along on the arms. The use of cords in this way on the arms of the swift has been found to be objectionable, owing to their notkeeping the skein properly in position and on account of their not being readily shifted to adjust the skein. These objections have been overcome by means of this invention, in which wooden The hub is bored ra-.

trunnions or bearings of the spindle being formed by the pointed ends of the spindle.- VVithin the arms are located radially-movable rods or bars 3, limited in their outward movement by means of a pin 4 in each rod 3 engaging a slot 5 in each arm'2. The bars 3 and sockets in arms 2 are preferably square to give a steady bearing to the bars 3, as shown in Fig. 3 The inner ends of the bars 3 rest against a coiled spring 6, located in the hollow arms 2, and by their tension serving to hold the bars 3 in extended position.

Upon the outer end of each of the bars 3 is mounted a cross-bar 7, over which a skein of silk is placed, the skein being held from 05 slipping off laterally therefrom by means of pins 8 at the ends of bars 7. The pins 8 correspond to the ends of the parallel radial arms extending from the hub in the old form of swift, and the cross-bars 7 correspond to the cords extending crosswise and connected to each pair of parallel radial arms and over which the skein extends.

The skein of silk on the swift in this invention extends over the bars 7,-and is held steadily thereon by the tension of the springs 6 holding the bars 7 outward against the skein. The silk is permitted to spread out on the bars 7 and cannot get loose, as the bars 7 are held steadily against the skein by a the springs (i, with a steady tension always maintained in the skein. 7

All of the foregoing parts are formed of wood to secure lightness, except the springs, the stops 4, and the central spindle-rod,which are of metal. The object of thus forming the swift is to render it just as light as possible, so it may be rotated without breaking the finest'or weakest strand of silk.

The skein can be beaten on the swift by c placing the hand inside of the skein and beating ita little, which makes the ends straight and spreads the skein out, thus making it less apt to catch again.

hen an end of the skein gets caught or tangled, it can be loosened in less time than it can 011 the old form of swift by giving the skein av snap with the fingers, which causes the1 springs to give and at once loosens the en 3y means of this invention, also, the skein is more easily adjusted on the swift than with the old form. Curved cross-bars have also been used; but no pins 8 were provided, and hence the skein can be beaten without 1131110"- ing it from the swift or reel; but with such curved cross-bars the tendency is to crowd the silk to the center, making it liable to tangle, and if the skein were beaten it would fall off.

Having thus described our invention, what we claim as new, and desire to secure by Letters Patent, is-

The herein-described swift, comprising a hub, radial hollow slotted arms projecting from the hub and immovable toward or from each other, the bars 3, sliding in said arms and provided at their outer ends with crossbars 7 and pins 8, the stops 4, passing through
