T0 @ZZ whom t mag concern.-

Be it known that we, HENRY WILDE and THOMAS Oosenovn, citizens of the United States, residing at New London, in the county of-New London and State of Connecticut, have invented a new and useful Bobbin or Quill finding Machine, of which the following is a specification.

This invention relates to improvements in machines for winding bobbins and quills, and is designed more especially for use in connection with the winding of iiner grades of silk and other yarns where undue strain and friction cause frequent breakage during the winding operation.

A further object of the invention is to construct a winding-machine in which the bobbin or quill holder is automatically adjusted to present successively fresh winding-surfaces as the winding operation progresses and, further, to provide a winding-machine in which the bobbin or quill is held on a non-revoluble support that is adjusted longitudinally, receiving a step-by-step movement during the winding operation.

A still further object of the invention is to construct a winding-machine in which the winding operation will be automatically stopped when the bobbin or quill is full.

A still further object of the invention is to construct a winding-machine including a hollow revoluble spindle into which the bobbin or quill enters, the latter being moved vertically by the traverse-rail while the spindle is held from longitudinal movement.

With these and other objects in view, as will more fully hereinafter appear, the invention consists in the novel construction and arrangement of parts hereinafter described, illustrated in the accompanying drawings, and particularly pointed out in the appended claims, it being understood that various changes in the form, proportions, size, and minor details lof the structure may be made without departing from the spirit or sacriiicing any of the advantages of the invention.

In the accompanying drawings, Figure 1 is an end elevation of a portion of a windingmachine constructed in accordance with the invention. Fig. 2 is a side elevation of a portion of the frame. Fig. 3 is a view of a number of the parts shown in Fig. 2, drawn to an enlarged scale. Fig. 4 is a transverse sectional elevation of one of the spindles. Fig.

5 is a plan View of the same. Fig. 6 is a detail sectional plan view of the belt-shifter and its support. Fig. 7 is a rear elevation of a portion of the traverse-rail together with the `bobbin-holder.

Similar numerals of reference are employed to indicate corresponding parts throughout the several figures of the drawings.

In the drawings there is shown a portion of a winding-machine including an end frame 1, a spindle-rail 2, and a traverse bar or rail 3.

The end frames have bearings for the reception of a horizontally-disposed shaft 4, carrying a number of shafts 5, over which extend driving-bands 6 to the several spindles, or the usual drum may be employed, if desired. At one or both ends of the shaft 4 are pinions 8, intermeshing with gears 9, and each of said gears is mounted on ashort shaft 10, adapted to a bearing in the end frame, the opposite end of the shaft at the outer side of the frame carrying a pinion 11, which intermeshes with two gears 12, that are mounted on stud-shafts 13. The pinions 12 have elongated hub portions 14, carrying cams 15, against which bear pins or antifriction-rollers 16, carried by the inner ends of a pair of rock-levers 17, that are pivotally mounted on studs 18, projecting from the frame.

In the upper portion of the frame are bearings for the support of a pair of horizontallydisposed traverse-rail rock-shafts 19, having rocker-arms 20, that are connected by links 21 to the rock-levers 17, and said rock-shafts 19 will receive an oscillatory movement at each revolution of the cams 15. On the spindlerail are arranged standards 23, which also eX- tend through guiding-bolts near the ends of the traverse rail, and on each standard is mounted an elongated lower sleeve 24, above which isa second sleeve 25, although the two lsleeves may be formed integral, if desired.

The lower end of the sleeve 24 has an enlarged collar or Harige 26, which rests on a forked arm 27, projecting from the rock-shaft 19, and the movement of the rock-shaft is thus transformed into a vertical movement, the traverse-rail being raised and lowered any desired distance in accordance with the character of the bobbins or-quills being wound, and this may be adjusted byproviding the rocklever 17 and rocker-arms 20 with slots in order that the point of connection of the links 21 may be made at a greater or less distance from the fulcrums of said members, and thus alter the throw.

In each traverse-rail is an opening for the reception of the lower end of a hollow standard 29, through which extends a rod 30, that may be formed of round wire of proper diameter, the rear face of the rod being provided with ratchet-teeth 31, with which may engage a spring-pawl 32, the opposite end of which extends through a suitable opening in the hollow standard. The spring-pawl has a forwardly-extending portion ruiming through a guide-opening in the traverse-rail and terminating at the point of the rail in a pushbutton 34, which may be forced in for the purpose of disengaging the pointed end of the pawl from the rack-teeth, and thus permit the moving of the rod 30. The rod receives a step-by-step upward movement during the operation of the machine and is locked in each new position by the pawl. f

1n the spindle-rail are bearings for the reception of spindles 40, the shank portions of said spindles extending through the rail, and their upper heads, which are preferably in the form of inverted cones, rest above the top of the spindle-rail. At the lower end of the spindle-shank are arranged a loose pulley 41 and a fast pulley 42, the loose pulley being uppermost, and driving-band 6 may extend around either of these pulleys, running idly with the loose pulley after the bobbin has been wound.

At a point adjacent to each of the spindles and guided in suitable opening in the spindlerail is a vertical guide-rod 47, the upper end of which is bent at a right angle and is provided with an eye 48, through which extends the rod 30, and the lower end of the rod 47 rests on a spring-pressed pivotally-mounted belt-shifter 49. Thebelt-shifter 49 is substantially in the form of a bell-crank lever, its apis on the surface of the fast pulley 42. /VhenV the winding of the bobbin has been completed, the top of the bobbin will engage against the eye 48 and raise the rod until its lower end is clear of the shoulder 52, after which the spring 50 is free to turn the shoulder on its fulcrum until the shoulder 53 engages against the end of the rod, and during this movement the driving-band will be shifted from the fast pulley 42 to loose pulley 41. In order to permit of the manual adjustment of the shifter at the commencement of the winding operation, each of such shifters is provided with a thumbpiece 54, which may be grasped by the spinner and turned to shift the band back to the fast pulley 42, but excessive movement is prevented by a shoulder or arm 55, which forms a part of said shifter.

Each spindle 40 is hollow for its entire length, the lower portion of the bore being approximately cylindrical, while near the upper portion it is slightly tapering and at the top is enlarged to form a circular chamber 57, in which is placed a ring 58, that may be formed of vulcanized fiber or of metal, and said ring is grooved at its lower edge to form a ball-race for the reception of an annular row of bearingballs 59, that rest on a ball-rest formed bythe wall of the chamber 57. rIhe internal bore of the ring 58 is tapered to correspond to the tapering winding of the bobbin or quill, andv said ring is confined in place by means of a holding-ring 60, that is secured' to the top of the spindle. although no clamping or binding action will be exercised and the ring may be at any time freely held from movement while the spindle continues to revolve.

Extending at an oblique angle to the main bore of the spindle and communicating therewith is a thread-passage 62, at the upper end of which is an eye 63, formed of porcelain or other like material, in order to keep the thread from contact with the metal, and the thread or other material to be wound passes up from the spool or spools on the spool-rail up through the hollow spindle and eye and is thence wound upon the bobbin.

In the operation of the device a bobbin is secured on the tapering end of the bobbinholding rod 30, and the bobbin and rod are lowered until the bobbin is within the ring 58 and in contact therewith. The winding operation is then started, the spindle rotating rapidly around the bobbin and winding the thread or yarn thereon. During the winding operation the traverse-rail is raised and lowered, and the accumulated yarn will again cause the bobbin to make contact with the ring 58 during the downstroke of the traverse-rail. The traverse-rail, however, is continuing its downward movement while the bobbin and rod remain stationary. This causes the springpawl to click over one or more teeth on the rod 80, and the traverse-rail in again elevating the bobbin will move to a somewhat higher point than before. This operation will continue, andas often as thread accumulates in suflcient quantity to stop the bobbin by contact with the ring 58 the bobbin will be raised higher and higher until finally its upper end comes into contact with the ring 48 and raises rod 47 to permit the changing of the belt or band from the fast pulley to the loose pulley through the operation of the shifter, and this stops the operation. The spinner will then raise the bobbin further and after removing the filled bobbin will put a new one in place and then after first forcing back the pushbutton 34 will lower the rod 80 and bobbin until the latter is in Contact with the ring 58. The shifter 49 is then turned by means oi' the thumb-piece 54 and the bobhin is shifted to the fast pulley 42, the operation continuing as before.

The machine constructed in the manner described may be run at a very high rate of speed, and owing to the fact that it contains but comparatively few parts will need but very little repair or adjustment.

Having thus described the invention, what is claimed isl. In winding machinery, arevoluble winding member, a bobbin-carrier, means operable through the thread or yarn on the bobbin for imparting progressive step-by-step movement to the bobbin-carrier in the direction of its length, and means for locking said bobbincarrier in the position after each movement.
