IwIACHIIIE FOR VJINDING VTARP SHEETS.

Application filed February 5, 1925. Serial No. 6,978.

To all whom it may concern:

Be it known that I, EDWI E. Garrison, a citizen of the .United States, residing at Chester, in the county of Delaware and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Winding Warp Sheets, of which the following is a specification.

My invention relates to winding machines and is primarily designed for winding a binder thread upon the warp sheets which pass through the solutions employed for mereerizing yarns.

In mercerizing yarns, strands of yarn have usually been grouped in rope "form and a number of groups are concurrently led through the mercerizing solutions. A bind ing thread is wound spirally about each group to hold loose ends of threads which may be broken in the mercerizing process to their group and prevent their clinging to and being wound around the rollers in the mercerizing mechanism. This requires a winding unit for each group. It is common practice to provide mechanism capable of dealing with 24 groups at one operation and this involves providing 24 winding units. It has recently been found advantageous to group the strands slde by side 1n single ply, thereby forming a s ngle warp sheet, and to bind the entire warp sheet with a single thread instead of binding each group separately.

The object of this invention is to provide a machine for winding, or unwinding, warp sheets or other continuous sheets which may require such winding or unwinding.

I have illustrated my invention in con nection with asingle ply warp sheet but it is adapted for use with continuous sheets of any type. I i

In the -drawings,

Figure 1 is a topplan view,

Figure 2 a side'elevation,

Figure 3 a section on line 33 of Figure 2,

Figure 4 a section on line H of Figure .2,

Figure 5 a vertical section through one form of spool carrier and spool,

Figure 6 an enlarged detail of a thread guide, and

Figure 7a side elevation of another form of spool with the thread guide.

In the drawings, 1 indicates the frame of the machine, 2 the top or table, 3 cross bars, 1 a guide slot in the table through which the warp is led, 5 an oblong raceway of slot type encompassing the warp and having guide walls 6 and 7 within and upon which a spool-carrier 8 travels, 9 a drive sprocket and 10 a companion sprocket both disposed beneath the raceway, 11 a sprocket chain carried by the sprockets, encompassing the warp and having one of its links 12 d etachably connected with a bearing block 13 adapted to support a spool-carrying spindle 14, 15 a sprocket chain spaced from chain 11, disposed parallel thereto and in the same horizontal plane therewith and detachably fixed to a series of brackets 16 extending from the frame, 17 a sprocket wheel fixed to the spool spindle and meshing with chain 15, and 18 the spool which carries the binding thread 19. The spool is rotatable upon its spindle 14 and is mounted upon spool-carrier 8. The spool-carrier, shown in detail in Figure 5, preferably consists of a sleeve 20 having an annular flange 21 and an enlarged part 22 and is threaded at its upper end to receive a stepped ball bearing 23 having annular flanges 2A and 25. The upper flange .25 carries a friction disk 26 upon which spool 18 is seated. The lower flange supports the carrier upon the guide walls 6 and 7 .of the raceway and flange 21 holds the carrier against upward displacement. Enlarged part 22 fits in the raceway slot and serves as a guide block for the spool carrier. As the spool is seated upon friction disk 26, it is free to yield to any unusual strains. A bracket 27, extending from the spool carrier, carries a standard 28 upon which a thread guide 29 is adjustably mounted. The thread guide has twofiXed members or eyes 30 and 31 extending therefrom and adapted to receive the binding thread 19. A shaft 32 is rockably mounted in the guide and carries, a crank arm 33 which carries, at its free end, an electrical contact member 34-, adapted to engage with a fixed contact member 35 extending from the guide, the Com tact member being in a normally open circuit including a switch which controls the motor. The guide is provided, between the stems of eyes 30 and 31 with a socket 36 and a block 37 fixed to shaft 32 is rockably seated in the socket. A pin 38 extends from the block in a plane between eyes 30 and 31. The binding thread 19 as it goes from the spool to the warp sheet passes through the eyes and over pin 38. The tension of the thread normally holds the crank arm in raised position and contact member 34 out of contact but, if the thread should break or the tension cease for any cause, the weight of the crank arm causes it to drop and close the circuit. Brushes 39 and 40 are mounted upon the spool carrier and are connected by wires 41 and 42 with contact members 34 and 35 on the thread guide. The brushes are adapted to respectively engage conducting strips 43 and 43 mounted upon insulating brackets 44 extending from the frame. Strips 4-3 and 48 are in circuit through a source of current 4;?) with a solenoid switch 46 which controls the motor 47 and engagement of contact members 34: and closes the circuit through the solenoid switch and stops the motor. 7

Drive sprocket 9 is mounted upon a shaft 48. A drive shaft 49 carries a spiral pinion 50 which meshes with a spiral gearbl on shaft 18 and imparts motion to the shaft and consequently to the drive sprocket and the movable chain.

- The thread spool shown in Figures 2, 3 and 5 is in the form of a cylinder. In Figure 7 I have shown a cone-shaped spool 23 which is mountedin the same way as spool 23 but the'standard 28 is extended and the thread guide 29 is disposed above instead of alongside the spool.

In operation, the binding thread which I has been wound upon the spool, leads from the spool through eye 30, over pin 38 and through eye 31 to the warp sheet. Motion being imparted to drive sprocket 9 from drive shaft 49, sprocket chain 11, to which spool carrier 8 is connected, is caused to travel continuously around the warp sheet thereby causing the spool carrier to travel in raceway 5 around the warp sheet. As the spool and thread guide are mounted upon the spool carrier, they also travel around the warp sheet and cause the thread to be wound spirally thereon. As the spool travels rotary motion is imparted to its spindle lt by sprocket wheel 17 meshing with fixed chain 15. As the spool is seated upon friction disk 26 which is carried by a ball bearing member it is free to yield to undue strains. In case the binding thread should break, crank arm 33, which has been held in raised position by the tension of the binding thread upon pin 38, will drop by gravity thereby bringing contacts 34 and 35 into engagement and closing the circuit through solenoid switch 46 and thereby stopping the motor.

While I have described my invention as taking a particular form, it will be understood that the various parts may be changed without departing from the spirit thereof. and hence Ido not limit myself to the precise construction set forth, but consider that I am at liberty to make such changes and alterations as fairly come within the scope of the appended claims.
