TWISTING-MAC'HINE FOR YARNS, COTTONS, AND THE LIKE.

Application filed November 24, 1920.

To all whom it may concern:

Be it known that I, ALLEN ARTHUR Bow- ERMAN, subject of the King of Great Britain, and a resident of Hope Bay, in the Province of British Columbia, Canada, have invented certain new and useful Improvements in Twisting-Machines for Yarns, Cottons, and the like, of which the following is a specification.

My invention relates to improvements in mac iines for twisting yarn, cotton, silks and the like, or for making the same into spools, and the object of my invention is to devise machine capable of accomplishing this object in simple, practical, and highly satisfactory manner.

I attain this object by the construction illustrated in the accompanying drawings in which- Figure 1 is a side elevation of the machine.

Fig. 2 is a front end view.

Fig. 3 is a rear end view.

Fig. 4 is a detail view in perspective of the cylinder.

Fig. 5 is a detail view of the roller driving mechanism.

Similar figures of reference indicate similar parts throughout the several views.

1 indicates generally the front end frame of the machine consisting of the. side uprights 2 and 8 connected together by upper and lower transverse members f and 5 respectively, while 6 indicates generally the rear end fra .ie consisting of the side up rights 7 and 8 connected together by the upper and lower transverse members 9 and 10, the upper transverse member 9 being provided with a plurality of spaced vertical pins 11. shown in Fig. 3, on which are rotatably mounted bobbins 12 filled with the material to be twisted, a guide plate 13 for the threads being mounted on the frame in advance of the bobbins having separate notches 1s for each thread to run in, as shown in Fig. 8. 15 indicates a roller mounted on the frame 1 for supporting the threads at the front end of the machine.

Rotatably mounted between the front transverse members a and 5 is what may be termed the cylinder of the machine, indicated generally by the numeral 16, consisting of upper and lower circular plates 17 and 18 connected together by bars 19, 20, and 21, the upper plate being provided with a central tubular journal 22 extending ro- Specification of Letters Patent.

tatably through the member 4-; While the lower plate is rotatably mounted on a shaft 23 which extends at its opposite ends through the plate 18 and lower transverse member 5, being rotatable in a bearing 24!: fitted into the member 5, bevel gears 25 and 26 being secured to the opposite ends of the shaft, as shown more particularly in Fig. 5. A sheave 27 is secured centrally to the underside of the plate 18 and through the sheave the shaft 23 also passes freely. I

28 indicate a shaft rotatably mounted on the cylinder 16 provided with a bevel gear 29 meshing with the gear 25 and'having toward one end a spur pinion 30 meshing with a spur gear 81 secured to one end of a roller 32, this roller being .rotatably mounted on a shaft 33 one end of which is secured to the bar 19 of the cylinder.- A similar roller 34- is mounted rotatably adjacent the upper end of the cylinder on a shaft 35 also scoured at one end to the bar 19, as shown more particularly in Fig. 2. At suitable points on the bar 19 between the rollers 32 and 3% arms 36 and 37 are pi'votally connected so as to be capable of being swungto and remaining in any adjusted position, each of which arms carries at one end a guide roller, 38 and 39 respectively. 40 in dicatcs the main driving shaft, operated by any suitable means, which shaft is mounted transversely of the machine at the rear thereof and is provided with a cone gear 41 belt-connected to a corresponding cone gear 42 secured to the shaft 13 rotatably mounted on the front end of the machine, this shaft 413 being provided with a bevel gear lt meshing with the bevel gear 26 on the shaft 23, while 45 indicates a sheave secured to shaft 10 connected by a rope 46 to the sheave 2'? on the lower plate 18, as shown in Fig. 1.

The manner in which the machine operates may be briefly described as follows. The respective threads from the bobbins are taken and carried forwardly over the roller Patented A110". 2, 1921."

15, being then gathered together at their the guide rollers and thus the sides of the loop areprevented from flying outwardly as it is rotated. If the machine be now started in operation the cylinder will be rotated by means of the rope 46 while the lower roller 32 will also be rotated by the gear mechanism disposed between it and the shaft 48, as hereinbefore described, so that the threads are unwound from the bobbins and formed into a skein by the rotation of the roller 32 and at the same timethe twisting is effected by the rotating cylinder. It will of course be understood that the number of threads and the amount of twist in the finished skein may be readily determined and controlled by the respectivespeeds at which the roller and the cylinder are driven.

From the foregoing it will be seen that I have devised a simple and inexpensive twist ing machine for yarns and the like which is hi hly practical and efficient.

What I claim as my invention is 1. A twisting machine comp-rising a frame, a cylindrical member mounted vertically on the front end of said frame, said member consisting of an upper circular disk having a central tubular journal and a lower circular disk having a central aperture and a sheave on its'underside concentric with the aperture and through which it extends, said disks being connected together by spaced vertical bars, spaced upper and lower rollers rotatably mounted on one of said bars, the lower roller being provided at one end with a gear, a suitably supported driving shaft, a driving connection between said shaft and said gear, and means for supporting a plurality of filled bobbins so that the free ends of the respective threads therefrom nay be gathered together and passed through the said tubular journal and looped around said horizontal rollers.

2. A twisting machine comprising a frame, a cylindrical member mounted vertically on the front end of said frame, said member consisting of an upper circular disk having a central tubular journal and lower circular disk having a central aperture and a sheave on its underside concentric with the aperture and through which it extends, said disks belng connected together by spaced vertical bars, spaced upper and lower rollers rotatably mounted on one said bars, the lower roller bemg provided at one end with "a gear, a rotatable shaft carried by said cylinder having a gear at one end meshmg with the roller gear and a bevel gear intermediate its length, a shaft extending vering with the aforesaid bevel gear and a bevel gear on its lower end, an intermediate shaft rotatably mounted on the frame having a gear; meshing with the lower'bevel gear of the vertical shaft, a maindriving shaft, a driving connection between the main shaft and intermediate shaft, a driving connection between the main shaft and the said sheave, and means for supporting a plurality of filled bobbins so that the free ends of the respective threads therefrom may be gathered together and passed through the said tubular journal and looped around the said horizontal rollers.

3. A twisting machine comprising in combination, a plurality of stationary spool supports, a rotatable frame having a single aperture through which the several strands from the spools associated with said sup ports are adapted to be passed into the frame, a plurality of rotatable rollers disposed to rotate about an axis at right angles to the axis of rotation of said frame, and means for rotating said frame and oneof said rollers.

4;. A method of twisting together a plurality of strands and winding the twisted strands into a skein, which consists in pass ing the several strands through a relatively small opening in a stationary member, then forming the ends of the strands into a loop extending over a pair of spaced rollers disposed with their longitudinal axes at right angles to thatof the opening, rotating said rollers about an axis coincident with that of the opening and simultaneously rotating one of said rollers about the longitudinal axes thereof.

5. A twisting machine comp rising a frame,

a cylinder rotatably supported at its ends by said frame and equipped at one of said ends with a central opening through which the strands to be twisted are introduced into the frame, a pair of spaced rotatable rollers within the cylinder extending transversely thereof, the ends of the said strands being adapted to be passed over the said rollers and secured to form a single loop embracing both of the rollers,and means for simultaneously rotating said cylinder and one of the rollers to twist the strands together and to form the twisted strands into a skein.
