SPECIFICATION forming part of Letters Application filed June 13,1899.

To all whom it may concern.- Be it known that I, ALFRED 13. Moses, of E'aston, county of Bristol, State of Massachusetts, have -invented an Improvement in" Winding-Machines, of which the following description, in connection with the :accompanying drawings, is a specification, like letters on the drawings representing like parts.

My invention is an improved winding-machin-e particularly adapted for windin g yarn, my improvements relating more particularly v to the means for mounting, guiding, and maintaining the proper pressure of the thread guide, certain details of improvement also relating to the mounting and adjustment of the quill.

The various details of construction and particular features of invention contained in my 5 new machine will be more fully explained and the invention more particularly defined in the following description, reference being had to l the accompanying drawings.

In the drawings, Figure l is a top plan view of sufficient portions of my machine to make the invention readily understood. Fig. 2 is a front elevation thereof. Fig. 3 is a lefthand end elevation. Fig. 4 is a broken detail of the quill-spindle and adjacent parts, the connections being shown in section subst-antially on the line 4 4., Fig. 1. Fig. 5 shows in broken detail the thread-guide support and adjacent parts, partly in vertical longitudinal section. Fig. 6 is a vertical cross-section taken on the line 6, Fig. 5. Fig. 7 is a sectional View similar to Fig. 6, showing a modification. Figs. 8 and 9 are longitudinal vertical sectional views showing two means for permitting the swivel action of the threadguide as the cop builds up, and Fig. 10 is a sectional detail on line 10, Fig. 1.

The driving mechanism and throw-cam arrangement herein shown are not claimed herein.

Power is derived from a pulley a, coupled by means of any suitable clutch mechanism a and clutch-lever a to usual cone-pulleys a at, the latter operating a gear-pinion a which meshes with a drive-gear a, connected with and driving the throw-cam of. A beltshifter a is provided for shifting the belt carried by the cone-pulleys a a.

ingly The parts above described are all substan- Patent n eveaev, dated iea 18, 1901.

Serial No. 720,362. (No model.)

tially as shown in my application, Serial No. 684,585, filed June 27, 1898.

The thread-guide or guide-button b is carried at the end of an arm I), provided with a suitable rib or bracket b perforated to slide on a guide-rod b supported in special manner, presently to be described. The arm I) has its hub b shrunk onto the end of a thin tubetr, supported by internal ribs 1) on a bar or rod b in substantially the same manneras shown in'my above-mentioned application. In my said application, however, this tube was reciprocated by carrying a roll at one side traveling in the throw-cam and a guide pin traveling in a slot adjacent the rod b, but on the opposite side thereof from the throwcam. I have found, however, that a much smoother and more uniform reciprocation of the thread-guide is obtained by placing the direction-slot between the throw-cam and the bar If and throw member tube b and accord- I have herein shown a slot 0, adjacent the rod 12" and between it and the throw-cam a in-which the stud b carried by the tube 19 operates, the free end of said stud entering the groove of the throw-cam and serving to reciprocate the threadguide. As herein shown, the slot 0 is provided in one edge of a casing or housing a, which I employ as a convenient frame for the adjacent portion of the machine and in which the adjacent parts are j ournaled; but it will be understood that the guide-slot 0 may be provided in any other suitable manner, provided its location is as stated. As herein shown, I ha-ve made-the quill-spindle stationary, so that as the threadmass builds up the quill doesnot swing away from the thread-guide; but instead thereof the thread-guide swings away from the thread mass, and the mechanism by which I accomplish this constitutes a chief part of my present invention.

Viewing Figs. 5 and 6, in connection with Figs. 1 and 2, it will be seen that I provide a sleeve d within and projecting from the hollow upper end of a stationary bracket (1, and on this projecting sleeve I mount a hub (P, which supports eccentrically the guide-rod b already alluded to, so that as the thread mass builds up the thread-guide can raise its guiderod 19 simply by rotating the hub (1 thereof on the supporting-sleeve (1. As is well understood, however, it is necessary for the proper winding of the thread or yarn that the thread-guide should have a constant and considerable pressure on the thread mass, and accordingly I secure this pressure by means of an automatic frictional resistance, preferably in the form of a frictional strap or collar (1 to the lower side of which is suspended by a rod (1' a suitable weight d the result being that all tendency of the threadguide to leave the thread mass isresisted, and the pressure thereof on the thread mass is kept uniform by the constant frictional resistance of the strap or collar of, subject to the weight d In Fig. 7 I have shown another means of securing the frictional resistance, said means comprising a brake-shoe or collar d having a stem d supported in a hollow post d and normally held in constant frictional engagement with the hub d by means of a spring (1", adj ustableby a set-screw (1 In order that as the thread mass builds up the thread-guide may lift without inconvenience to the tube 6 I may make the latter in two sections, as shown in Fig. 8, in which said sections are shown as provided with annular ribs Z7 Z1 permanently secured thereto, the former of said ribs carrying a flange 19 with an'inturned lip Z2 which embraces the rib b and constitutes a swivel-coupling, permitting the portion of the tube b which carries the thread-guide to turn independently,

of the other portion.

Instead of the coupling mechanism shown in Fig. 8 I may mount the. hub Z) ofthe thread-guide directly on the end of the tube 'b", as shown in Fig. 9, where it will be seen that I have threaded the parts together by extremely fine threads, so that the slight turning occasioned by the thread-guide will not materially afiect the relative longitudinal position of the parts.

Referring now more particularly to Fig. 4, it will be seen that the quill-spindle e, for supporting any usual quill or bobbin e and mounted in an adjustable-bracket e pivoted at a is shown as arranged obliquely to support a conical quill, and in order that the spindle may be readily connected to and driven by the drive-shaft f I have coupled the same thereto by a universal joint, the adjacent end of the drive-shaft fbeing provided with a disk f, preferably flanged, as at f and containing a pin f to enter a slot 6 of a flange or disk a, rotating with the spindle e. The bracket 6 constitutes a journal-support and swings from a horizontal position to an inclined position for maintaining the Winding-surface (by which I mean the surface on which or above which the thread-guide rests) in perfect parallelism with the path of reciprocation of said thread-guide, said swinging movement, both of the spindle and the jour-- nal support, being shown herein as accomplished by the adjustment at the pivot e but I mean the word swinging to include any means whatever of adjustment for moving said support and permitting the spindle to swing from a horizontal position to the inclined position shown in Fig. 4, or vice versa, it being necessary only that the j ournal-bearing shall move similarly as the spindle swings between the two positions required, respec- Yively, by a parallel quill or a conical quill. Heretofore various connections have been provided, and in my before-mentioned application I have shown gearing for this purpose; but the gearing is expensive and inconvenient and other constructions are cumbrous, while the one shown is simple and automatic in its accommodation to its different posi tions, the slot being in an inward position relatively to the pin f when it is uppermost, as shown in Fig. 4, and being toward the free end of said pin when it is lowermost or in an opposite position to that shown in Fig. 4. Moreover, this connection enables me to adjust the angle of the spindle e to any minute degree desired, inasmuch as a slight change in the angle thereof does not necessitate any attention whatever to the connection.

While I do not intend to restrict myself to the particular kind of universal joint shown, yet for various reasons this joint is to be preferred. For instance, usually it is more convenient simply to-take off the bracket 6 and spindle when a cone has been running and replace them by another bracket and spindle when it is desired to use a parallel or tubular quill, and in such case'it is obvious that the slot-and-pin connection shown facilitates such replacing of parts, inasmuch as the slot simply pulls off from the pin or slides thereon, as the case may be. It will be evident that with this connection the quill-spindle will be rotated with equal facility in either its 0blique or horizontal position. I prefer to employ this connection for the reason that it is extremely simple, inexpensive, and easily kept in order.

In operation as the thread-guide is reciprocated the tendency of the tube 5' and adjacent parts to vibrate or bind on the rod 5 is largely counteracted by the position of the guide-slot c, as already explained, and the smooth and uniform. As the thread mass builds up the thread-guide is permitted to swing by reason of the swivel connection joining the two parts of the throw-tube b and yet the thread-guide is constantly held down with the requisite pressure on. the thread mass by reason of the resistance offered by the guide-rod 11 due to the constant frictional pressure of the brake-like device engaging the hub (Z thereon.

Various other mechanisms have been suggested for maintaining the proper pressure of the thread-guide upon the thread mass,

and in my before-mentioned application I have shown a very desirable meansfor ac-- complishing this object; but it will be evident to those skilled in the art that the pres-.

ent. apparatus possesses many advantages ICC running of the parts is rendered extremely thereover, requiring no particular skill in running it, but, on the contrary, being absolutely automatic and always uniform irrespective of the size of the thread mass and the speed of the machine.

If it is desired to change from winding conical quills, as shown, and to wind parallel quills or tubes, the change may be instantly efiected simply by removing the bracket 6 and spindle carried thereby and replacing the same by a bracket, which carries the spindle in a horizontal plane, inasmuch as the coupling mechanism automatically accommodates itself to the new conditions, it being unnecessary to remove or change in any way any of the driving parts.

While I have herein shown and described certain preferred mechanisms for carrying out my invention, I donot limit myself to any of the details herein shown otherwise than as specified in the claims.
