llVlPROi/EMENT IN GUIDES FOR SILKWINDERSV.

Specification forming part of Letters Patent No. 137,417, dated April l, 1873; application iiled September 25, 1872.

To all whom it may concern:

Be it. known that I, J AMES H. CAMPBELL, of Willimantic, county of Windham, State of Connecticut, have invented a new and useful Improvement in Machine for Winding Silk, of whichthe following is a full, clear, and exact description, reference being had to the accompanying drawing makin g part of this specilication, in which- Figure l is a perspective view. Fig. 2 is a longitudinal section. Fig. 3 represents a modiiication of my invention. Y

Similar letters of reference denote corresponding parts in all the figures.

It is well known by all who are familiar with the manufacture of silk goods that the raw silk is of such a hard Wiry nature that it will when running rapidly over a stationary guide cut into it, thus making a new path for itself, and rendering the operation of said guide very imperfect when winding bobbins, because these new or false paths will not accommodate the various sizes of silk that are necessary to run over the same guide, and thus cause a great waste of material and labor by breaking down 7 the silk at every knot or enlarged place thereon. With a view to obviate this defect revolving guides have been employed; but as heretofore constructed they produced so much friction upon their bearings that the slight friction of the thread of silk upon this surface is not sufficient to keep them in motion 5 hence they will sometimes stop and cut in the same manner that an ordinary stationary guide does. The object of this invention is to produce a revolving guide which shall run with but little friction, whereby the cutting action of the silk above referred to is obviated. To this end the invention consists'in mounting a revolving guide in the opposing ends of two shafts or arms, the said shafts or arms being made adjustable longitudinally, whereby the aforementioned advantages are attained, as will be hereinafter fully explained.

In the drawing, A represents the traverse beam or bar, which may be of any usual or approved construction, as may be the bobbins and other mechanism not particularly referred to in this specification, and which need not therefore be shown or described. B is the bedplate, made preferably of metal, and adjusted on the traverse-beam by means of screws, which pass through slots b, or other equivalent device. C are knee-standards formed in one piece with or fastened to bed-piece B. In many cases it may be advantageous to have one or both of these knee-standards fastened to the bed-plate by set-screws, and be capable of being turned around, thus releasing the other parts, and making it convenient to clean, oil, or change any of them. D D are supporting arms or bars mounted in standards 0. In the drawing I have represented bars D D as being screwed into the standards G in such manner that they may be adjusted thereinthat is, their inner ends may be made to approach or recede from each other-for a purpose which will be explained. It is apparent that the standards might be moved upon the bed-plate to accomplish the same end. E is a grooved guide wheel or sheave, mounted upon pivot-bearings formed on the ends of arms D D, and it will be readily seen that by adjusting said arms the guide may be always maintained in the desired position relative to the bed-plate and the receiving-bobbin.

Now, it will be easily seen that any lateral motion of the guide E relative to the traverse beam will counteract the purpose of t-he traverse-beam, it being the oce of this traversebeam to so carry the running silk as to perfectly fill the receiving-bobbin from end to end. Anything less than a perfect bobbin-t'. e., having the silk piled to any extent in the center of the bobbin more than at the bobbin ends or headscauses a proportionate amount of waste of material, as the higher portions of the silk will slide down toward either bobbinhead, and prevent its being rewound from the imperfectly-shaped bobbin.- To remedy this is one of the offices of the adjustable arms I) D, as the pivot-bearings on the ends of said arms present but very slight surface to sides of guide E, and thus perfectly control its lateral motion and still cause but the slightest friction. d are jam-nuts on arms D to securelyllock them in position. F are metallic guides employed to conduct the silk to guide E. They are made preferably of metal, and secured to bed-plate B by means of in-turning and clasping shanks or lips f, which are made preferably elastic, and retain their position by their own gripe, or are held by being clasped between the bed-plate andthe traverse-beam.

Many other methods might be adopted for fastening the guidesF in place; as, for instance, the shanks f might be secured to the bed-plate by means of a set-screw; or grooves might b e made in the sides of the bed-plate, into Which the lips or Shanks.;C could be clasped by their own elasticity.

rIhe operation of this device will be understood without further description; and it will be readily seen that by the employment of the pivot-bearing to support and adjust the revolving guide E the friction is very much reduced, and that my method of supporting the guides F upon the bed-plate enables me to use very short arms to mount the guide E, thus making a cheap, compact, andelective construction.

As a modiiication of this construction, I may mount the guide either loosely or rigidly upon a small spindle, e, Fig. 3, supporting the spindle in sockets in the ends of arms D D, the position of the guide being adjusted by the opposing ends of the arms. In the practical working of this modication, in many cases it would be better to have the spindle so tted that it could be removed from the guide and be replaced by a new one as it became worn, because this could be done with much less expense than replacing the whole guide and spindie.

It is evident that spindle e might be made in one piece with one of the arms; but for convenience of manufacture and of replacing, I prefer to make them separate; and a small spindle might be used with stationary arms arranged upon each side of the guide to prevent lateral movement; but there will always be more orless wear of the ends of the arms, after which the guide will not feed the bobbins perfectly. When desired, oil-holes e may be bored in the guide F in order that the pivotbearings vmay be oiled without removing guide F from the position shown in the drawlng.

Having thus described my invention, what I claim as new, and desire to secure by Letters Patent, is v l. The herein-described device for guiding silk or other thread to a bobbin, consisting of a grooved pulley or sheave mounted upon the two adjacent ends of the arms D D attached to the bed-plate B.

2.v The combination of the sheave E and the supporting-arms D D with the guides F F.

3. The combination of the she-ave E and the supporting-arms .D D with the traverse-beam A.

In testimony whereof l have hereunto set my hand this 14th day of September, A. D. 1872.
