KlNK-PREVENTER FOR SILK-SPINNING MACHINERY.

SPECIFICATION forming part of Letters Patent No. 487,334, dated December 6, 1892.

Application filed March 2, 1892.. Serial No. 423,540. (No model.)

To aZZ whom it may concern:

Be it known that we, EDWIN OLDFIELD and PETER FLYNN, both citizens of the United States, and residents of Norwich,in the county of New London and State of Connecticut, have made certain new and useful Improvements in Kink-Preventers for Silk-Spinning Machinery, which improvements are fully set forth and described in the following specification, reference being had to the accompanying two sheets of drawings.

This invention relates to machinery for spinning or for doubling and twisting silk, and has for its object to prevent the kinking of the fine strands of silk when the machine is stopped; and said invention consists in a simple device formed as a wire loop which may be brought into service at the proper time to hold the strand of silk taut.

Our invention further consists in mechanisms connecting said wire loops with the belt shipping mechanism in such manner that the starting or stopping of the frame will serve automatically to bring into use or withdraw the entire series of kink-preventers throughout the frame.

It is a commonly-known fact that when a silk-spinning frame is stopped-as, for example, at the close of the days work or at the noon-hoursuch strands of silk as become slackened immediately double upon themselves and become badly kinked.- Owing to these strands being very fine and easily broken, the operation of straightening out such kinks becomes both a tiresome and ex-' pensive one. Frequently the strands are broken and have to be knotted, in which case the quality and value of the spun silk are materially lessened.

The drawings hereto annexed illustrate our invention, Figure 1 being a cross-sectional view of portions of a spinning-machine frame, showing in proper relation to each other the delivery-spool, the take-up bobbin, and such other portions of the machine as are immediately connected with our invention. Fig. 2 is an enlarged perspective view of the beltshipper rod, also one of our kink-preventing devices, and of the parts by means of which action of the kink-preventers is efli'ected when the shipper-rod is moved in either direction, as hereinafter explained in detail. Fig. 3

shows the driving-pulleys of the machine with portions of the belts coacting therewith, and also explains the manner of connecting the shipper-rod with the principal of said belts. In Fig. 4 I have shown the shaft which carries the series of kink-preventers, and also a supplemental shaft or rod upon which said preventers rest when in service. Fig. 5 is a front view, in elevation, of several of the delivery spools with their spindles and the belt by means of which the series of spindles is rotated. This View also shows the kink-pie venters in their elevated position-that is to say, the position which they occupy during the operation of spinning.

In the drawings, the letter a denotes the delivery-bobbin suitablymounted upon spindles b, here shown as provided with a pulley b, which is engaged and rotated at proper times by a belt a, which engages the rear side of the entire series of spindle-pulleys throughout the length' of the machine, as perhaps best explained by Fig. 5. The spindles bare journaled in the usual manner in the lower machine-rail b.

c denotes the usual take-up roll at the top of the machine; 6', a guide-eye, and f the strand of silk, the parts thus far described being the same as in silk-spinnin g machines of ordinary construction.

Referring to Fig. 3, g denotes a vertical shaft bearing a loose pulley g and fast pulley g of equal diameters, which are engaged and controlled by a main drivingbelt h, and also a third pulley 9 fast on the shaft g, which last-named pulley carries the belt 0, already referred to in connection with the spindlepulleys.

h denotes an angle lever fulcrumed at 71 1. and having a loop or eye at the end of one of its arms through which the belt h passes, the free end of the other arm of said lever being In the rear of the series of bobbinsa (about i machine, upon which is loosely mounted a series of angle-armslc, corresponding in num;

her with the spindles of the frame, each an glearm having secured to its horizontal portion a wire is, which extends outward and terminates in a ring-shaped coil thatis concentric with the upper. end of the. bobbin and atleast. a complete circle of which is in the same plane and touches the bobbin with which it coacts at all points when the wire is dropped upon said bobbin. The several angle-arms may be prevented from lateral displacement upon the shaft 1'' either by suitable collars secured to said shaft on either.v side. of;- the angle-arms or by pins driven into said shaft, as shown in Fig. 2. Between .-s haft and the. line 1 of bobbins is a supplemental; shaft m- 0a which. is'suppprtedby the.free ends of armsgm', secured; .to the .shaft in such man-ner that when said shaft ;is gpa xgtly rotated tthevarmsm and rod m are liftedco p din 1 em-ti e se .o kn set venters lo rest by gravity on the. rod and it will be; understood thatwhensaidarod is raised the. kink-preventers are carried: upward at the. sametime...
