THREAD GUIDE FOR SPINNING MACHINES Original No. 1,500,258, dated July 8, 1924, SeriaLNo. 676,752, filed November 24, 1923. Application for reissue filed January 21,

This invention has reference to guides for wlndlng or spinning machlnes,where a thread is drawn from one spool or bobbin and wound upon another spool. 1

The object ofthe present invention is to provide a thread guide that will have its portion adapted to engage a thread of considerable extent or area, and which member can be readily shifted or adjusted whereby a considerable number of different surfaces can be brought to position for engagement with the thread,'and by a comparatively small and simple adjustment on the support for the guide member.

A further object of the invention is to provide a special guide arm to prevent the thread movement away from its desired engaging osition, and which member is also made adustable to be shifted corresponding with the shifting movement of the thread engaging portion. v

In the accompanying drawing showing one embodiment of my invention,

Fig. 1 is a side elevation of the device.

Fig. 2 is a longitudinal section.

Fig. 3 is a transverse section.

Fig. 4 is a similar view showing Wear in I the disc by the thread.

Fig. 5 shows a modified form of the device with the guide or thread retainer, in side elevation.

Fig. 6 is a transverse section device as shown in Fig. 5. 'In theuse ofsuch devices as these, especially where the memberthat engages the thread is formed of a non-metallic substance such as porcelain, it is found that the friction of the thread passing against the guide surthrough the Serial No. 82,831.

ment, and without shifting the supporting member.

In the arrangement shown herein I provide a support in the form of a disc or spool 7 that is adjustably carried by a supporting member in the form of a rod or stem 8. The disc is shown as provided with a comparatively deep annular groove 9. The disc is provided with a bore 10, into which projects the end portion 12 of the stem, that is bent to extend at a right angle to the stem 8. This bent portion is passed through the bore of the spool, and the extremity is provided with a suitable fastening means, such as a nut 13 en gaging the screw thread extremity 14; of the stem. It will be understood that when this nutis tightened against the side face 15 of the spool, the latter will be pressed on the bent portion of the stem until the opposite face 15' of the spool will engage the stem 8.

Upon loosening the nut 13 the spool can obviously be turned on the bent stem and a different portion of the grove 9 will be brought to the path of movement of the thread 6, as indicated in Figs. 3 and 4, where as shown in Fig. 4 the shaded portion 4; represents a worn portion of the spool groove, that by slightly turning the spool will cause a fresh unworn part to engage the thread 6, and the nut 13 is again tightened to secure the spool in this position.

While such an arrangement would provide a considerable number of adjustments for the spool on the stem, I preferably provide abutment portions on the spool for engagement with the stem. As shown the spool on the side 15 is provided with a series of projections forming notches or radial groves 16', of a size to fit the stem 8 that is brought to registertherewith as indicated in Fig. 2. As shown I provideeight of these radial grooves that will give eight different positions of adjustment for the spool on the stem and which will be equally spaced apart. When any one place becomes worn by the thread 6 the nut 13 is loosened and the spool slightly vmoved to bring the groove away from the stem 8, and then the spool is turned to bring an adjacent groove 16 opposite the stem, when the nut is again tightened. Each fresh surface of the spool groove is in the same position relative to the path of the thread 6.

It is further desirable to provide a kind of guide or retainer for the thread to prevent its getting out of the spool groove. In Figs. 5 and 6 I show a guide formed by a rod 20 having a loop 21 adapted to be clamped between the nut 13 and the adjacent face of the spool, as clearly shown in Fig. 6. The end portion 22 of the guide extends transversely across the plane of the spool, and also that of the stem 8, as indicated in Fig. 6. This member and the stem 8 will prevent the thread from moving out of the groove. lVhen the nut is loosened to adjust the spool on the stem, the guide arm can also be shifted to retain it in proximity to the stem. The side 15 of the spool may also be provided with a series of projectors forming notches or radial grooves 23 arranged to engage the stem 20, and which grooves are an ranged similar to the grooves 16 on the op posite side. lVhen the spool is shifted en the stem to engage another groove with the stem, the guide arm is also shifted in a similar manner, to engage the next groove, and will thus maintain its position relative to the supperting stem 8.

It will be noted, by referring to Fig. 5, that the retainer 20 is angularly bent, so'that the extension 22 thereof overlies the supporting stem 8 permitting the ready introduction of thread therein by a sidewise motion of the thread. In order to accommodate the desired angular relation of the retainer to the supporting stem in the grooves 16 on opposite sides of the guide 7 the said grooves are spaced in staggered relation to each other on opposite sides and they therefore maintain the retainer and support rod 8 in the desired relation.
