THREAD-WINDING MACHINE.

SPECIFICATION forming part of Letters Patent N0. 788,632, dated May 2, 1905.

Application filed August "7, 1902. Serial No. 118,730-

To It whom, it Wuty concern.-

Be it known that I, CHARLES H. CREssY, a citizen of the United States of America, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Thread- Winding Machines, of which the following is a specification.

This invention relates to thread-winding machines, and particularly to machines of this class adapted to wind a plurality of shuttle or other bobbins simultaneously, these bobbins being wound on a paper or other tube. After winding the tube is cut between each bobbin in the usual manner in this art. While, however, this is the preferred use of the machine and the use to which it can be most advantageously put, it may be used for' winding cops or other form of bobbins.

The object of the present invention is to improve the construction of a machine of this class in respect to simplicity and compactness of construction and ease of operation; and the invention consists in the construction described in the following specification and pointed out in the claims forming a part thereof.

The invention is illustrated in the accompanying drawings, in which Figure I is a perspective view of a machine constructed according to my invention. Fig. 2 is a sectional plan view of part of the base of the machine and some parts carried thereon, said section being taken on line 2 2, Fig. 1. Fig. 3 is a partlyseotional perspective view of a portion of the machine to which' the thread-guide is attached; and Fig. 4 is a side elevation of one of the flier-arms which carries the thread-guide and of a spring thereon, whereby the thread-guide is pressed toward the spindle. Fig. 5 is a longitudinal section through the lower end of the flier-arm and the sleeve of the thread-guide.

In its essential features this machine consists of a non-rotatable spindle on which the cops are wound and around which the arms of a flier rotate, one of said arms carrying the thread-guide. This flier is mounted on a tubular shaft whose axis coincides with that of the spindle, and on which shaft there is located a spool-carrying platform.

The frame of the machine is indicated by a, and it is provided with the base I), which maybe bolted or otherwise secured to a standard c or other form of support. On the base I) of the frame is a projecting portion (Z, on the front side thereof, in which is rigidly mounted a depending sleeve 6, within which the spindle f is carried and in which said spindle has a vertical sliding movement, the spindle being otherwise stationary. A paper or other tube 9 is fitted over the top of the spindle f, and the bobbins h of thread are wound on this tube in separated relations one to another. A lever '21, connected to the lower end of the spindlef by a pair of links, may be operated to draw the spindle f downward against the tension of a spring whereby the tube 9 may be stripped off the upper end of the spindle, the latter moving through a suitable bushing 70, within which it fits closely for this purpose. Upon the release of the lever i the spring 9' moves the spindle up again into the position shown in Fig. 1.

Mounted in a suitable boss m, cast on the forward end of the frame a, is a verticallydisposed tubular shaft W, said boss constituting the bearing for said shaft. On the upper end of this shaft is a spool-carrying platform 0, which is splined to the shaft, so as to permit the latter to have a vertical reciprocating movement through the hub of the platform while the latter is rotated with the shaft. This spool-carrying platform is preferably circular in shape, and thespools p are disposed on pins or otherwise around the platform. Preferably the top of said shaft n eX- tends above the platform 0 to a point about midway between the ends of the spools. The lower end of this shaft 'n extends through the boss m, and there is secured thereto a head carrying the flier-arms g and r, and the axis of said shaft coincides with the axis of the spindlef.

A collar 8 is secured to the shaft n, and it has an annular groove with which a fork t engages, which is operated in a manner which is described farther on to impart to the shaft n reciprocating vertical movements, said shaft being adapted to be thus moved in its bearing m and also to thus move through the hub of the spool-platform 0.

Mounted on the shaft 11 below the spoolcarrying platform is a pulley u with a geared hub 12, having an antii'riction thrust-bearing 2 on the boss m. The pulley u is splined to the shaft n, so that while a rotary motion can be transmitted to the shaft and the parts rotatable therewith through the medium of a belt 1), running over the pulley u, the shaft can also have a vertical reciprooatory movement independent of the pulley. The geared hub 12 of the pulley u forms one of a train of gears whereby a vertical shaft to is rotated, which shaft is suitably supported on the frame of the machine and carries at its lower end a cam-wheel x, in the periphery of which a camgroove y is out. An arm 2 on a rockshaft 2 engages with said cam-groove y, the fork 1. also being secured to said rock-shaft, to the end that the rotation of the cam may, through the described connections, impart vertical reciprocating movements to the shaft n by the connection therewith of said fork. The speed of the cam-shaft w is varied in the ordinary way by reversing the position of the gears 3 and 3 which are rigidly attached to each other and detachably mounted for rotation on a stud adjustable on the frame, so that the gears may be reversed and the gear 3 may be made to mesh with the gear 1 and the gear 3 with the gear 2, and vice versa. By varying the speed of the cam-shaft w the cam y is caused to rotate at a higher or lower speed, whereby the vertical reciprooatory movements of the shaft n will be changed, whereas the speed of rotation thereof is constant. Therefore the angle at which the thread is wound on the bobbin it may be thus also changed.

On one of the arms of the flieras 1", for instance-there is mounted a sleeve 4, which may be swiveled thereon in any suitable manneras, for instance, by means of a headed screw 20, the threaded shank of which engages a tapped hole in the end of the flierarm, whereby the sleeve may be freely rotated. (See Fig. 5.) To this sleeve the thread guide 5 is adjustably secured by means of screws 6 or in any other suitable manner. This thread guide 5 is of hard steel, and its forward edge is provided with slots 7, through which the threads 8 run and whereby these threads are guided onto the tube 9 to form a bobbin of a given width.

A11 enlarged view of a portion of the sleeve 4 is shown in Fig. 3 partly in section, and within said sleeve is located a ring 9, through which the end of the flier-arm 7* passes, and encircling the latter is a spiral spring 10, the upper end of which is secured to the arm and the lower end of which is adapted to enter one of the holes 12 in said ring, the latter being fixed in the sleeve 4 by soldering or otherwise.- By disengaging the ring 9 from the end of the spring 10 and shifting the latter to another hole in said ring the pressure of the thread-guide in its contact with the tube may be varied, the function of this spring 10 being to hold the thread-guide in constant contact with the tube or with the bobbins as they are built up in the operation of the machine. The thread-guide is permitted at all times to swing on the arm of the flier on which it is carried.

The belt 12, which drives the shaft n, may run over a tight and loose pulley, (not shown,) clutch-operated or otherwise, by means of an arm 13, which is shown in Figs. 1 and 2. Said arm is locked in position to allow the machine to run by a horizontally-swinging lever 14, which is clearly shown also in said figures. This lastnamed lever is pivoted at 15 in a slot running across the base of the machine, one end 16 of said lever being turned outwardly in position which permits it to be struck by an arm 17, secured by a screw 17 to the sleeve 4 in such position that as the bobbin h fills up this arm will beswung circumferentially on the flier-arm 1 far enough around the latter to strike the end 16 of the lever 14 when the bobbins h have attained a certain size. This contact between the arm 17 and the lever 14 will throw the end of said lever which holds the arm 13 in restraint out of engagement with the latter, and thus permit a spring or weight to operate said arm 13 to unship the belt 4) or to unclutch the driving-pulley over which it runs. By shifting the arm 17 toward or from the spindle f it may be adjusted to come in contact with the lever 14 sooner or later. The preferred way of adjusting this arm is to wind a bobbin of the size desired, then loosen the arm 17 and after setting the flier in the proper position adjust the arm 17 to bear on the end 16 of the lever 14 and secure said arm in this position.

To thread up and operate this machine, spools are placed on the pins on the platform 0, and a thread from each spool is assed down through the shaft n, and all the t eads gathered together are then passed through two eyes 18, secured on the sleeve 4, the second or lower one of which lies substantially midway between the two ends of the threadguide. From this lower eye the threads all run separately, one to each of the slots 7, their ends being-passed around the tube g.

To start the machine, the ship er on the arm 13 is operated by swinging t e arm 13 forward, where it is held by the operator until the nose 14 of the lever 14 is engaged with the arm 13, and it will be readily seen that the nose 14 of the lever 14 and the arm 13 will be held in engagement by the tendency of the arm 13 to assume its normal position, forcing said nose against the base until the lever 14 is automatically disengaged by the arm 17 contacting with the part 16 of the lever. The rotation of the shaft n will now cause the thread to be wound on the tube on the spindle f into bobbins of the desired diameter, the traverse of the thread in buildin up the bobbins being effected by the vertical movements of the flier imparted thereto in the manner described. When the bobbins have attained the desired diameter, the thread-guide has been moved outwardly to partially rotate the sleeve 4 on the flier-arm against the tension of the spring 10, and the arm 17, which extends from the side of the sleeve, has been moved circumferentially with the sleeve, causing the arm to be projected in the path of the end 16 of the lever 14, and when it strikes the end of the lever that element is operated to stop the machine, as has been above described. The lever i may be 0 erated and the tube g strippedfrom the spind e, as described, and a new tube may then be put on the spindle and the operation repeated.

While two flier-arms have been shown, the only one that is operative is the one which carries the thread-guide. The other arm in the construction shown and described herein serves merely to counterbalance the arm car, rying the thread-guide.

Having thus described my invention, what I claim, and desire to secure by Letters Patent of the United States, is
