To all whom it may concern;

Be it known that I, JOHN RYAN, a subject of the King of Great Britain, residing at Winnipeg, in the Province of Manitoba and Dominion of Canada, have invented new and useful Improvements in Twisting-Machines, of which the following is a specification.

This invention relates to machines or de- Vices for twisting yarn preparatory to reeling the same to form skeins, and it has for its object to produce a simple and eflicient device whereby two or more threads may be easily and expeditiously twisted to form a yarn.

A further object of the invention is to provide a simple and efficient stop motion whereby in the event of the breaking or running out of any one of the threads the twisting device may be stopped.

A still further object of the invention is to produce a simple and eflicient twisting device which may be run at high speed without danger of undue vibration.

A still further object of the invention is to produce a simple and eflicient twisting device the shaft of which as well as one of the shaft bearings shall be slotted for the insertion of the threads required to form the am. y With these and other ends in view which will readily appear as the nature of the invention is better understood, the same consists in the improved construction and novel arrangement and combination of parts which will be hereinafter fully described and particularly pointed out in the claims.

In the accompanying drawings has been illustrated a simple and preferred form of the invention, it being, however, understood that no limitation is necessarily made to the precise structural details therein exhibited, but that changes, alterations and modifications within the scope of the claims may be resorted to when desired.

In the drawings,Figure 1 is a View in front elevation showing a single unit of the improved twisting device and a portion of the supporting frame for the same, Fig. 2 is a sectional View taken on thejline 22 in Fig. 1. Fig. 3 is a sectional view taken on the line 33 in Fig. 1. Fig. 4 is a sectional view taken on the line 44 in Fig. 1. Fig. 5 is a sectional view taken on the line 55 in Fig. 1. Fig. 6 is a sectional detail view 1 front elevation diagrammatically showing a plurality of units of the improved twisting device and related parts. Fig. 8. is a verti= cal sectional view taken on the line 88 in Fig. 1.

The frame A of the improved device may be of suitable dimensions to accommodate any desired number of units or twisting devices, and said frame comprises in its construction a bench including front and rear members 1, 1* a foot piece 2 and a cap piece 3, said members being usually sustained in parallel relation by uprights, one of which is shown at 4.

Each unit of the improved twisting device comprises a shaft 5 which extends vertically through the bench 1 and the lower end of which is stepped in the foot piece 2. Each of the shafts 5 is provided at its upper end with a fru'sto-conical.enlargement 6 having a bore or recess 7 and a slot 8 which communicates with said bore or recess.

The cap plece 3 has a recess 9 constituting ,a bearing for the frusto-conical portion 6,

said bearing being formed adjacent to the front edge of the cap piece; the slot or aperture 10 at the front of the recess 9 may when desired be brought into registry with the slot 8 of the shaft. Each shaft 5 carries a disk or table 11 upon which any desired number of spindles 12 are equidistantly disposed to support the spools or bobbins 13 holding the thread which is to be twisted. In the drawing three bobbin holding spindles have been shown, but any desired number from two upward may be used.

Pivotally connected with the shaft 5 adjacent to the upper face of the disk or table 1 is a plurality of levers 14, one of which extends radially from the shaft adjacent to each bobbin carrying spindle. Each lever 14 is provided with an upwardly extending arm 15 havingan eye 16. The shaft 5 is also provided at a suitable distance from the upper end with a plurality of radially disposed arms 17 the number of which corresponds to that of the levers 14, said arms being provided adjacent to their outer ends with eyes 18. Pivotally mounted upon the rear member 1 of the bench adjacent to and in rear of the shaft 5 is an arm or lever 19 which may be guided through a keeper 20 upon the front member 1 of the bench. Pivotally connected with said lever is a finger 21 which when placed in an upright in Fig. 1, is adapted to engage a notch 23 in a slide 24 which is movably supported in keepers 25 upon the front edge of the bench 1. To this slide reciprocatory motion is imparted when the machine is in operation by any suitable means, such as a cam wheel 26 on the line shaft 27, said cam wheel being provided with a zigzag groove 28 engaging an arm 2-9 connected with the slide 24, which latter will thus be constantly reciprocated when the line shaft is in motion.

The shaft 5 of each unit is provided with a grooved pulley 30 connected by a quarter-- twisted band 31 with a grooved pulley 32 which is loosely mounted upon the line shaft, said grooved pulley 32 being provided with a clutch member 33 adapted to be engaged by a slidable clutch member 34 which is feathered or, keyed upon the line shaft. The slidable clutch member 34 is eng'aged by a bifurcated arm 35 associated with the arm or lever 19 which constitutes a shipping lever, a suitably arranged spring 36 being provided whereby the clutch member 34 will be normally held in engagement with the clutch member 33 of the loose pul- In connection with this device, reeling mechanism of any ordinary well known construction may be employed for the purpose of reeling or skeining the yarn as it comes from the twisting device. Such reeling mechanism may be driven in any convenient manner from the shaft 5 so that it will be stopped or started concurrently with the stoppage and the starting of the twisting mechanism.

From the foregoing description, taken in connection with the drawings hereto annexed, the operation and advantages of this invention will be readily understood by those skilled in the art to which it appertains. The thread coming from each cop or bobbin is threaded through the eye 18 of an arm 17 and through the eye 16 of the arm 15 assothe shaft may be provided with as many slots 8 communicating with the bore as there are threads to be twisted, although this is not deemed absolutely essential. As the twisted yarn issues from the bore of the shaft it passes to the reeling device, whereby it is reeled to form skeins, as is well understood. In the event of the breakage or running out of any one thread the lever 14, which has been sustained in an elevated position by such thread, will drop by gravity and will presently engage the finger 21 of the arm or lever 19, tilting such finger to theposition indicated in dotted lines in Fig. 1, and causing it to engage a notch 23 of the reciprocating slide 24. The shipping lever will thereby be moved in the direction and out of engagement with the clutch member 33 associated with the loose pulley 34. The latter thus becomes idle upon the line shaft, and motion of the twisting unit and associated parts will thus be instantly stopped. To start the unit, the operator merely releases the shipping lever 19 fromthe spring catch 37 and restores the finger 21 to an upright position where it is retained by the lateral projection 22. This may bedone while the lever 19 is held by the handle 21, and said lever is then moved in the proper direction to replace the clutch member 34 in engagement with the clutch member 33 where it will be safely retained by the action of the spring 36. It will thus be seen that each unit of the machine may be stopped automatically by the running out or breaking of a single thread and may be again started in motion without affecting the operation of the remaining units of the'maand of the bearing enable the threads to be conveniently and quickly inserted so that interruptions caused. by broken threads or from other causes will be of the shortest possible duration.

Having thus described the invention, what is claimed as new, is

1. In a twisting device, a twisting unit including a vertically supported shaft, a disk on said shaft having a plurality of upstanding spool carrying spindles, levers extending radially from the shaft and having arms provided with guide eyes, arms eX- tending radially from the shaft and having guide eyes, a line shaft, means for transmitting motion from the line shaft to the vertical shaft including a loose pulley having a clutch member and a slidable clutch feathered upon the line shaft, a shipping lever having a bifurcated arm engaging the slidable clutch member, said shipping lever being provided with a finger having a lateral extension whereby it may be supported in an upright position in the path of the levers extending radially from the vertical shaft when the said levers lie flat upon the disk, and a reciprocatory slide having a notch adapted to engage the finger when the latter is tilted.

2. In a twisting device, a twisting unit including a vertically supported shaft, a disk on said shaft having a plurality of upclutch member and a slidable clutch feath- V ered upon the line shaft, a shipping lever having a bifurcated arm engaging the slidable clutch member, said shipping lever being provided with a finger having a lateral extension whereby it may be supported in an upright position in the path of the levers extending radially from the vertical shaft when the said levers lie fiat upon the disk, a reciprocatory slide having a notch adapted to engage the finger when the latter is tilted, spring means to retain the slidable clutch member normally in engagement with the clutch member on the loose pulley, and a spring actuated catch to retain the shipping lever in retracted position.

In testimony whereof I have affixed my signature in presence of two witnesses.
