- the presentinvention relates to a spinningmachine regarded as standing ina class by itself described --in Letters Patent of the United States issued to me May 8, 1894, No. 519,491, and having in common with that machine a number of instrumentalities for the accomplishment of the'ultimate object; but the reason of the present improvements is to provide more efficient and practicable mechanism for carrying out the spinning operations and to further provide mechanisms for rendering this machine available for the spinning of rovings of widely-differing sizes and qualities and for the production of yarn also of widely-differing sizes, as occasions may require.
- the invention consists in the combinations of mechanisms and in the constructions and Vcombinations of parts, substantially as will scale from a complete full-sized factory operating spinning-machine comprising the present improvements.

- Fig. l5 shows powerparts shown in Fig. ll.
- Figs. 18 and 19 areelevations at right angles to each other, showing modication in the composition and arrangement of the variably-speeded driving mechanism ⁇ for the drawing-rolls.
- 2O represents the roving drum or cylinder, on which a spool 2l of roving bodily rests, the core-rod 10 of the spool being held against displacement by the forkedarms 11, the spool deriving a rotational movement for its delivery by reason of the corresponding motion intermittently imparted to the cylinder through frictional'engagement.
- the surface speed of the cylinder imparts a corresponding motion to the roving, so that if there is twelve inches of peripheral movement ofV the cylinder there will be substantially twelve inches of rovingdelivery,v no matter whether the spool is full or more or less depleted.
- 22 and 23 represent sets of delivery-rolls adjacent and axially parallel with the aforesaid cylinder.
- 24 represents a vibrator device located between the delivery-rolls and the twister-head.
- the said gear-wheel W represents a comparatively large spur gear-wheel mounted loosely and concentrically on the journal for thecylinder 20, and this gear is constantly and uniformly rotated by the spur-gear 52, which is interchangeable on the horizontal shaft 12,and which shaft has the bevel-gear 13 on its opposite end,which meshes with the bevel-gear 14 on the upright shaft 15, which is driven by the worm-gearing 16v 17 by the main shaft A.
- the said gear-wheel W has the series of small holes or sockets 51 at regular intervalsin any of which to receive a stud or pin 53, extending inwardly suflicien'tly far to comeinto engagement with the latch at, hereinafter described and explained. (See Figs. 1, 3, and 16.)
- main shaft A On one end of main shaft A is 'mounted a bevel gear-wheel b, meshing into bevel gearwheel b2 on shaft 3, having on its opposite end a pulley b4.
- a belt b runs around said v pulley and also around the loose pulley b5, a
- the roving drum or cylinder 2O is 'driven' from one of the delivery-roll shafts c6, which has chan ge spur-gear c7 and which meshes into the spur-gear cs, compounded with the spurgear cls, which compound gear is adj ustably mounted, as seenat 017, Fig. 4E, and said ⁇ gear c1s meshes into the spur-gear o9, which is fast to the shaft or arbor of the cylinder 20.
- the aforesaid spur-gear W provided with a series of socket-holes, has in' addition to the' laterally-projected detachable stud or pin 53, also at some point around in the circular line of the holes within its face or near such circular line, the laterallyprojecting shorter stud g. i
- a frame or lever P Pivoted on the end of the framing at 47 is a frame or lever P, (seen in Figs. 1, 3, and 16,) having the engagement member p,with which the shoulder d2 of the aforementioned latch has periodically an engagement and disengagement, ythe latch being under the stress of a spring a3, whereby it is maintained inits position of engagement except at such times as it is forcibly moved or depressed from such position.
- the lever P has engaged therewith ⁇ the rod g', which connects one member of the intermediately-pivoted two-armed lever g2, to the ⁇ opposite arm of which is connected the rod g4, which carries the belt-shifting fork g for the aforementioned belt b'.
- the small roll or stud g projecting inwardly from the face of the continuously-rotating gear-wheel W, comes at the proper instant in contact with the member 19 of the swinging lever P and forces this to the left, as the parts are relatively seen in Fig. 3, sufficiently far to permit the latch a to spring upward and hold the lever P from returning to its normal position, as it has tendency to do by reason of the weight Q7, connected to the end of the chain g3, which is attached to the belt-shifter vmechanism with which the lever P is connected.
- FIG. 7L is a brake-shoe pivoted at t' to a suitable supporting part of the machine, and operating in conjunction with this brake-shoe is the inclined bar h3, carried by Y. the depending lug h4 at the-end of the beltshifter rod g4, this last-mentioned part being most clearly seen in Fig. 16.
- the inward movement of the belt-shifter rod, whereupon the belt is carried onto the loose pulley insures the impingement of theinclined bar h3 against the brake-shoe to force it just as the belt is fairly off from the fixed pulley into braking engagement with said fixed pulley for the manifest result.
- the relative location of the studs or projections gand 53 governs the time or duration of roving-delivery at each draw or complete operation of the machine represented by one complete rotation ofthe said gearwheel XV. Hence if the stud 53 is placed in a socket-hole farther behind the projection g, considered relative to the course of the rotation of these parts, the stud g always being considered as leading or ahead of the stud 53, the roving will be delivered duringa greater length of time than if the stud 53 were placed less far behind the stud g.
- the size of the interchangeable gear c3 determines the quantity of the roving delivered during the delivery period acquired, as just above explained.
- lach twister has a driving-band B3, passing around twister-head drum ,132, driven from main shaftA by means of the changeable and adjustable gear-wheels 62 63 G4. (Shown in the end View Fig. 4.)
- This gearing is changeable and adjustable to vary the normal and continuous speed of the twisters by substituting the gear 62 on the drum for a larger or smaller gear and correspondingly adjusting the intermeshing gear 63, intermediate between this and the main-shaft pinion 64.
- the roving from the spool through the delivery-rolls and through the twister-head passes from the jaws of the latter to the drawing-rolls C C2, which are continuously and variably driven.
- the draw-rolls are driven bythe sprocket-wheel f fixed on the common shaft C for the one side series of draw-rolls C2,
- worm e5 On Vinner end of cone-shaft is fixed a worm e5, which engages the worm-wheel e4, fixed to such delivery will be faster than the rate at which the drawing is done during the time of delivery, and when the delivery begins the sprocket-wheel f', which is fixed on drawingroll shaft being driven, will drive the crossshaft e faster than the rate at which the cone D has been driving the sleeve e2. Therefore ratchet-'wheel e3, which is seen as provided fast to the shaft e, will run ahead of its pawl c6, clicking past it during part of the time that the cone iscontinuously though uniformly speeded.
- the sprocketwheel f which is loose on delivery-roll shaft c6, will have its pawl f3 click past the teeth of the ratchet-wheel, which is fast on saidA **d in order to insure relatively to the degree of elongation of the stock an increased twisting thereof by the continuously-rotating twister-head B, which result is accomplished by the friction-cone belt D2.
- the cone E drives cone D through said belt in the manner common in variable cone-driving mechanism.
- the cam F operates the cam-roll on lever G, to the outer end of which is attached the fiexible connection 62, having winding engagement on pulley-drum 63, fast to which drum is a larger drum G4, (see Fig. 5,) in wind- IOO IIO
- the said ca'm F is fastened adj ustably to the gear-wheel W, the object of which, in a general way, is to insure that the cam will be so relatively set that when the latch has been tripped or released and the delivery stopped the cam will begin to draw up the friction-belt of and between the cones and decrease the speed of the drawing-rolls, and the decrease of the speed, both in amount of decrease and also-in the suddenness or slowness thereof, is of course governed by the throw and grade of the cam.
- the spinning-machine which has been constructed in accordance with the present invention as exemplified in the accompanying .drawings is seen to embody a let-off cylinder or roller 20 and a driving connection for said let-off cylinder, consisting of a constantlyrunning wheel (instanced, the one b4) -and mechanism of driving connection between such wheel and the controller, comprising devices for rotating the cylinder for any required intervals relative to the rotation of said constantly-running wheel, (this involving the shaft c, gearing c3 c4, driving the deliveryrolls, which are geared to drive the cylinder, and the belt-shifter devices and operating means employing the wheel W with its studs or projections, and the latch d,) and.

- This head consists of a tubular body having journalsteps 72, intermediate of which is the grooved sheave 73, the upper spindle-like portion 74, having the closed rounded top 75 and considerably therebelow the sidewise-opening aperture 76, leading into the axial passage 77, continuing from the junction thereof down through the lower end of the device.
- This supplemental head M' is driven by drivingband 7 9 from the drum 78, suitably rotated in the same direction as the main twister-head drum B2, but at a somewhat lower rate of speed than said twister-head drum.
- the said head M is located j ust above the twister B, its axis being angular to the line ofthe run of the'roving from the delivery-rolls to its side, in which is the said aperture 76 for the entrance of the roving into the passage leading therefrom down through the head to also enter and pass to the twisting action of the twister-head B.
- the elongation or drawing of the roving is almost entirely performed in that portion thereof between the delivery-rolls and the TOO head M, each rotation of the head M impart- V ing a twist to the roving between it and the delivery-roll, which is most properly regarded as the drawing twist.
- the twister-head B running faster, (for instance, twice as fast as the head M in the same dir.ection,) imparts between its jaws and the part of the roving in tension on the cylindrical portion 74 of the said head M an additional twist, or a second twist, so that there is lessened liability of breakage of the roving between the jaws of the twister B and the draw-roll within the short distance between them, and also to prevent the roving from becoming parted anywhere between the draw-rolls and the place of tension engagement on the part 74 of head M, more especially at the time that this variable tension exists in its greater degree, which is just before it has made a complete turn around .said portion 74E and has fallen off therefrom.
- the delivery-rolls 23 22 are intermittently driven in the same l manner as has been already described, and the drawing-rolls are driven by the sprocketchain 43 during the delivery rotation of the delivery-rolls, and when the roving has been fully delivered the belt b' is shifted onto the loose pulley b5, said belt being always around the constantly-running pulley b4, and substantially the same devices illustrated in Fig. 16 may be utilized as the belt-shifter mech- .anism in the corresponding manner as described in the foregoing portions of this specication.

SPECIFICATION forming part of Letters Patent No. 622,836, dated April 1 1, 1899.
l Application filed January 14,1898. Serial No. 666,727. (No model-l` structurally widely different and operating in A a widely-different manner from the mule.
The present machine comprises mechanism for periodically delivering as required a certain amountof roving without draft, the
' amount delivered at each delivery period depending upon the size of the roving and the required size of iineness of the finished yarn and comprises improved means for operating and controlling the twisting and drawing mechanism, whereby the proper amount of drawing twist relatively to the amount that the roving is drawn or elongated may be secured in accordance with varying classes of spinning previous to thewinding of the yarn onto the bobbins.
The presentinvention relates to a spinningmachine regarded as standing ina class by itself described --in Letters Patent of the United States issued to me May 8, 1894, No. 519,491, and having in common with that machine a number of instrumentalities for the accomplishment of the'ultimate object; but the reason of the present improvements is to provide more efficient and practicable mechanism for carrying out the spinning operations and to further provide mechanisms for rendering this machine available for the spinning of rovings of widely-differing sizes and qualities and for the production of yarn also of widely-differing sizes, as occasions may require.
The invention consists in the combinations of mechanisms and in the constructions and Vcombinations of parts, substantially as will scale from a complete full-sized factory operating spinning-machine comprising the present improvements.

In this machine a suitably-designed framework is understood.
A represents the main shaft, having at the rear end of the machine the fast and loose pulleys 7 and 8 with driving-belt and beltshifter 9 and 9, Figs. 4 and 6.
IOO
2O represents the roving drum or cylinder, on which a spool 2l of roving bodily rests, the core-rod 10 of the spool being held against displacement by the forkedarms 11, the spool deriving a rotational movement for its delivery by reason of the corresponding motion intermittently imparted to the cylinder through frictional'engagement. The surface speed of the cylinder imparts a corresponding motion to the roving, so that if there is twelve inches of peripheral movement ofV the cylinder there will be substantially twelve inches of rovingdelivery,v no matter whether the spool is full or more or less depleted.
22 and 23 represent sets of delivery-rolls adjacent and axially parallel with the aforesaid cylinder. f
B represents the twister-heads, and adjacent them are the paired drawing-rolls C C2.
27 represents the spindles and bobbins.
24 represents a vibrator device located between the delivery-rolls and the twister-head.
W represents a comparatively large spur gear-wheel mounted loosely and concentrically on the journal for thecylinder 20, and this gear is constantly and uniformly rotated by the spur-gear 52, which is interchangeable on the horizontal shaft 12,and which shaft has the bevel-gear 13 on its opposite end,which meshes with the bevel-gear 14 on the upright shaft 15, which is driven by the worm-gearing 16v 17 by the main shaft A. l The said gear-wheel W has the series of small holes or sockets 51 at regular intervalsin any of which to receive a stud or pin 53, extending inwardly suflicien'tly far to comeinto engagement with the latch at, hereinafter described and explained. (See Figs. 1, 3, and 16.)
On one end of main shaft A is 'mounted a bevel gear-wheel b, meshing into bevel gearwheel b2 on shaft 3, having on its opposite end a pulley b4. A belt b runs around said v pulley and also around the loose pulley b5, a
. su pporting-arm c thereof detachably confined' fixed pulley b being alongside, said fixed and loose pulleys being on a horizontal shaft c, which is mounted to rotate in the journalbearing c2, which is adjustable by having the to a suitable lug of the framework by the clamp bolt and nut 18. (Indicated in Fig. 3.) On the opposite end of shaft @from the location of'the pulleys t5 b is placed a change-gear c3,detachably held in place by the nut 1.9,which gear meshes with the gear c4, fixed on delivery-roll drivin g-shaft c5, which, by the bevelgears 40, drives the shafts cG for and in common to one series of both sets or pairs of the delivery-rolls 23.
The roving drum or cylinder 2O is 'driven' from one of the delivery-roll shafts c6, which has chan ge spur-gear c7 and which meshes into the spur-gear cs, compounded with the spurgear cls, which compound gear is adj ustably mounted, as seenat 017, Fig. 4E, and said `gear c1s meshes into the spur-gear o9, which is fast to the shaft or arbor of the cylinder 20.
The aforesaid spur-gear W, provided with a series of socket-holes, has in' addition to the' laterally-projected detachable stud or pin 53, also at some point around in the circular line of the holes within its face or near such circular line, the laterallyprojecting shorter stud g. i
Pivoted on the end of the framing at 47 is a frame or lever P, (seen in Figs. 1, 3, and 16,) having the engagement member p,with which the shoulder d2 of the aforementioned latch has periodically an engagement and disengagement, ythe latch being under the stress of a spring a3, whereby it is maintained inits position of engagement except at such times as it is forcibly moved or depressed from such position. The lever P has engaged therewith `the rod g', which connects one member of the intermediately-pivoted two-armed lever g2, to the`opposite arm of which is connected the rod g4, which carries the belt-shifting fork g for the aforementioned belt b'.
After the drawing of a given delivered quantity of the roving has been completed and a new` delivery is to be given, the small roll or stud g, projecting inwardly from the face of the continuously-rotating gear-wheel W, comes at the proper instant in contact with the member 19 of the swinging lever P and forces this to the left, as the parts are relatively seen in Fig. 3, sufficiently far to permit the latch a to spring upward and hold the lever P from returning to its normal position, as it has tendency to do by reason of the weight Q7, connected to the end of the chain g3, which is attached to the belt-shifter vmechanism with which the lever P is connected. As the said lever P is thus swung to the position to be latched it, through-the said rod g', so swings the two-armed lever g2 that theA shipper-rod g4 moves to carry the beltvb' onto the outer or fixed pulley b, causing, through the mechanism heretofore described, simultaneously for a period the rotation both of the cylinder 20 and the delivery-rolls, both of these having the same surface speed, the cylinder and delivery-rolls being geared together by the gearings hereinbefore pointed out as provided at the end of the machine opposite from that at which said gear W is mounted, it being-remembered that said gear W, while rotating concentrically with the arbor of the cylinder 20, is not directly connected thereto; and thus while the lever P is held in its latched-back position and the belt heid'running on the fixed pulley h6 the roving will be delivered by reason of the rotation of the cylinder and of the delivery-rolls, and such delivery will continue during such portion of the rotation of the wheel WV as corresponds to the distance the stud 53 is from the projection g, for it will be manifest that so soon as the said stud 53 comes against and has a wiping bearing on and past the latch ct to depress it and disengage it from the swinging lever P the latter will automatically return to its original position, reversely placing the beltshifting mechanism with the belt on the loose IOO IIO
pulley b5. shaft c now has no drivingforce imparted thereto, and the delivery-rolls and cylinder have their rotational movement stopped, the stoppage being immediate by reason of the action of brake mechanism operative relative to the said fixed pulley 56 and which is pointed out in the drawings to consist as follows:
7L, Figs. 3 and 5-, is a brake-shoe pivoted at t' to a suitable supporting part of the machine, and operating in conjunction with this brake-shoe is the inclined bar h3, carried by Y. the depending lug h4 at the-end of the beltshifter rod g4, this last-mentioned part being most clearly seen in Fig. 16. The inward movement of the belt-shifter rod, whereupon the belt is carried onto the loose pulley, insures the impingement of theinclined bar h3 against the brake-shoe to force it just as the belt is fairly off from the fixed pulley into braking engagement with said fixed pulley for the manifest result.
The relative location of the studs or projections gand 53 governs the time or duration of roving-delivery at each draw or complete operation of the machine represented by one complete rotation ofthe said gearwheel XV. Hence if the stud 53 is placed in a socket-hole farther behind the projection g, considered relative to the course of the rotation of these parts, the stud g always being considered as leading or ahead of the stud 53, the roving will be delivered duringa greater length of time than if the stud 53 were placed less far behind the stud g.
The size of the interchangeable gear c3 determines the quantity of the roving delivered during the delivery period acquired, as just above explained.
The twisters are continually running. lach twister has a driving-band B3, passing around twister-head drum ,132, driven from main shaftA by means of the changeable and adjustable gear-wheels 62 63 G4. (Shown in the end View Fig. 4.) This gearingis changeable and adjustable to vary the normal and continuous speed of the twisters by substituting the gear 62 on the drum for a larger or smaller gear and correspondingly adjusting the intermeshing gear 63, intermediate between this and the main-shaft pinion 64.
The roving from the spool through the delivery-rolls and through the twister-head passes from the jaws of the latter to the drawing-rolls C C2, which are continuously and variably driven. When the roving is being delivered, the draw-rolls are driven bythe sprocket-wheel f fixed on the common shaft C for the one side series of draw-rolls C2,
through the sprocketchain 43 from the sprocket-wheel f, which is loose on deliveryroll shaft c, said shaft cG having fixed thereon the ratchet-wheelf2, the teeth of which are in engagement with the pawlf, which is carried on the said sprocket-wheelf. (See Figs. 1l and l5.) When the roving-delivery stops, the drawing-rolls vare driven by the variably-rotated cone D or by the mechanism attenuated in Figs. 18 and 19, which maybe employed in lieu of the cone-driving mechanism. The cone D is fast on a shaft therefor running in bearings suitably provided. On Vinner end of cone-shaft is fixed a worm e5, which engages the worm-wheel e4, fixed to such delivery will be faster than the rate at which the drawing is done during the time of delivery, and when the delivery begins the sprocket-wheel f', which is fixed on drawingroll shaft being driven, will drive the crossshaft e faster than the rate at which the cone D has been driving the sleeve e2. Therefore ratchet-'wheel e3, which is seen as provided fast to the shaft e, will run ahead of its pawl c6, clicking past it during part of the time that the cone iscontinuously though uniformly speeded. Now when the delivery of roving ceases the sleeve e:e and pawl e6 continuously revolving will, through the engagement of said pawl with its ratchet-wheel, drive the shaft e, and at 'this period in the operation the rotation of common shaft Cfor the drawrolls having the sprocket-wheel f' thereon will cause a corresponding run of the chain 43 without effect thereby, for, as may be understood on reference to Fig. 3, the sprocketwheel f, which is loose on delivery-roll shaft c6, will have its pawl f3 click past the teeth of the ratchet-wheel, which is fast on saidA duced in order to insure relatively to the degree of elongation of the stock an increased twisting thereof by the continuously-rotating twister-head B, which result is accomplished by the friction-cone belt D2. The cone E drives cone D through said belt in the manner common in variable cone-driving mechanism. Now as the drawing progresses after the delivery the cone-belt Diis drawn toward the large end of the cone D, and therefore toward the small end of the cone E, reducing speed of D, and consequently, through the connected mechanism, of the drawing-rolls, all this being controlled by the action of the cam F on the same shaft as the gear-wheel W, which is the arbor for the cylinder in the present instance, although not necessarily on this particular shaft. j
The cam F operates the cam-roll on lever G, to the outer end of which is attached the fiexible connection 62, having winding engagement on pulley-drum 63, fast to which drum is a larger drum G4, (see Fig. 5,) in wind- IOO IIO
a eas-Lese ing engagement with which is the flexible connection or chain 65,'connected to the sliding belt-shifter 66, mounted on slide-bar 67, said chain thence passing over sheave 68 and havingaweight onits end in order to keep the camroll end of lever G always closely against the rim of the cam F. The said ca'm F is fastened adj ustably to the gear-wheel W, the object of which, in a general way, is to insure that the cam will be so relatively set that when the latch has been tripped or released and the delivery stopped the cam will begin to draw up the friction-belt of and between the cones and decrease the speed of the drawing-rolls, and the decrease of the speed, both in amount of decrease and also-in the suddenness or slowness thereof, is of course governed by the throw and grade of the cam.
The spinning-machine which has been constructed in accordance with the present invention as exemplified in the accompanying .drawings is seen to embody a let-off cylinder or roller 20 and a driving connection for said let-off cylinder, consisting of a constantlyrunning wheel (instanced, the one b4) -and mechanism of driving connection between such wheel and the controller, comprising devices for rotating the cylinder for any required intervals relative to the rotation of said constantly-running wheel, (this involving the shaft c, gearing c3 c4, driving the deliveryrolls, which are geared to drive the cylinder, and the belt-shifter devices and operating means employing the wheel W with its studs or projections, and the latch d,) and. means which is capable of being changed (here the detachable and interchangeable gear-wheel c3 just above referred to) for causing or insuring during the period of time the let-off cylinder is being rotated any required extent of rotation thereof, together with the rotatable draw-rolls and rotatable twisters and driving means' therefor operative to insure such relative and timely speeds of rotation thereof that during the let-off the draw-rolls have proportionately a greater speed relative to the speed of the twisters than at the interval between the let-offs. l
By the provision in the spinning-machine of the peculiar type to which this invention pertains of instrumentalities and mechanisms for imparting thereto the capabilities last above set forth it becomes possible and entirely practicable to utilize the machine for operating on roving having variety within a very wide range both as to quality and the fneness or coarseness thereof, and for the production of yarns either fine or coarse, having, as compared with the roving delivered from the spool, much or little attenuation and having intermediate between its delivery and its winding onto'the bobbins comparatively little or a great degree of what in this art is known as the drawing twist.
For the productionfrom any given roving of yarn which is excessively fine I have augmented the capability of the machine by the provision of a series of supplemental heads which have in operation the double function of giving an added drawing twist to the roving and of also giving thereto in rapid succession a series of alternate tensionings and releases from tension, and the combination of such supplemental head in the machine is shown in Fig. 17 of the drawings, in which M represents the supplemental head, located directly above the twister-head. This head consists of a tubular body having journalsteps 72, intermediate of which is the grooved sheave 73, the upper spindle-like portion 74, having the closed rounded top 75 and considerably therebelow the sidewise-opening aperture 76, leading into the axial passage 77, continuing from the junction thereof down through the lower end of the device. This supplemental head M'is driven by drivingband 7 9 from the drum 78, suitably rotated in the same direction as the main twister-head drum B2, but at a somewhat lower rate of speed than said twister-head drum. The said head M is located j ust above the twister B, its axis being angular to the line ofthe run of the'roving from the delivery-rolls to its side, in which is the said aperture 76 for the entrance of the roving into the passage leading therefrom down through the head to also enter and pass to the twisting action of the twister-head B. The elongation or drawing of the roving is almost entirely performed in that portion thereof between the delivery-rolls and the TOO head M, each rotation of the head M impart- V ing a twist to the roving between it and the delivery-roll, which is most properly regarded as the drawing twist. The twister-head B, running faster, (for instance, twice as fast as the head M in the same dir.ection,) imparts between its jaws and the part of the roving in tension on the cylindrical portion 74 of the said head M an additional twist, or a second twist, so that there is lessened liability of breakage of the roving between the jaws of the twister B and the draw-roll within the short distance between them, and also to prevent the roving from becoming parted anywhere between the draw-rolls and the place of tension engagement on the part 74 of head M, more especially at the time that this variable tension exists in its greater degree, which is just before it has made a complete turn around .said portion 74E and has fallen off therefrom. l
It will be explained that the elongation of roving results by the draft on the roving between the ldraw-rolls and the delivery-rolls and in that portion having the least degree of twist-that is, the portion between delivery-rolls and head M-it being understood IIO fect is produced above said head M and by a combination of draft, twist, and rapid successive tensionings and releasings, so that it is brought down entirely to the required-fine'- ness at the time it engages and passes through the head M.
In Figs. 1S and 19 of th-e drawings Ihave shown driving connections for imparting the variable speed to the drawing-rolls, which maybe employed in substitution of the conedriving mechanism illustrated in the preceding drawings and hereinbefore referred to,this driving mechanism in no way altering the action or capabilities of the machine; 'but it can be run with less power than the conedrive. Y
Itisto be understood that the delivery-rolls 23 22 are intermittently driven in the same l manner as has been already described, and the drawing-rolls are driven by the sprocketchain 43 during the delivery rotation of the delivery-rolls, and when the roving has been fully delivered the belt b' is shifted onto the loose pulley b5, said belt being always around the constantly-running pulley b4, and substantially the same devices illustrated in Fig. 16 may be utilized as the belt-shifter mech- .anism in the corresponding manner as described in the foregoing portions of this specication. The pulley h6 next to the pulley b5 is fast on the shaft C. On the hub of the loose pulley b5 is a chain-wheel 85, around which passes the chain 86', which also passes around and drives the chain-wheel 87, on the hub of which is a pinion or gear wheel S3, which meshes into a gear-wheel 39 on the shaft 90, The scroll 92 is fast on said shaft 90, and it has throughthe cord 93 a flexible driving connection with the grooved drum 94 externally produced on the sleeve e2, which is mounted in the same way on the drawingroll-driving shaft e, as has been already described, the sleeve having the pawl e6 m ou nted thereon engaging in the ratchet-wheel e3, fast on shaft e. Cord K has a winding engagement with. grooved sleeve ve2, loosely mounted on shaft e, the same supporting a weight 95. Then belt b is on loose pulley b5, shaft 90 receives a constant and uniform speed through the action of driving connections 85 80 37, 33 and 39 therefore driving shaft e and the drawing-rolls at agradually-V i decreasing speed ascord 93 is being wound Ass 92 and wound up on drum 94 until the .de-v
scent of the weight is arrested by the stop or stud 97, which may be adjustable as to height.
'In spinning, itbeingsupposed that the relative time of delivery of roving to time of draw has been adjusted, and also during said time upon during the next roving delivery Weight 95 is permitted to descend and unwind cord 93 from the scroll onto the drum untilthe descent of the weight 95 has reached its limit at just the right instant as determined by the adjustable stop 97. This reversed rotation of the sleeve e2 is permitted by the pawl click.
ing over ratchet c3,and the loose pulley b5 has incidentallya rotational movement in unison with the scroll, because of the described connections between said loose pulley and the scroll-shaft 90, and this is all without effect on the shaft e. ingeared connection with the drawing-rolls at this time being driven from the head-works of the machine-that is, the roving-delivery mechanism.
This lastdescribed mechanism, while of i lighter structure than the cone-driving inechl anism, and The means for shifting the conebelt D2, hereinabove described, tend to siniplify and cheapen the machine, as Well as to economize power, and is believed to involve novelty and is accordingly claimed.
In the drawings are illustrated the mounting of the twister-heads on common supports orbars 100 for each side set thereof, which bars are endwise, movable in suitable ways 101 therefor, and means for impartinga bodily movement to each said bar, consisting of the connecting-rod 102, operated by the eccentric-pin 103 on the shaft 104, having the worinwheel 105, which meshes into the worm 10G on the vertical shaft 15. ersing motion to the twisters, whereby the r'oving delivered therefrom onto the drawrolls is not so delivered constantly at one point and whereby the wearing of grooves into the draw-rolls is prevented. It will be perceived also in the drawings that below the paired drawing-rolls are rolls 110 110,' all on a common shaft, having by belt 112, running around pulleys 113 111 on the drawing-roll shaft C and on the vcommon shaft for saidv TOO IIO
This imparts a travrolls 110, a rotation in unison with and in the same direction with the series of drawing-rolls vcoming upon said rolls will be wound thereupon, so that the attendant at such time as he is able to splice the break may readily do so and remove the slight accumulation of the yarn from the take-up rolls.
The twister-head used in duplicated series in this machine consists of a hollow tubular v cylindrical body 114, having sheave or whirl 115 thereon, and a narrow yarn-gripping iinger 11.6, integrally formed and longitudinally extended. Short ear-pieces 117 are provided on the end ot the body 114 opposite said iinger 116, and a second yarn-gripping finger 11S is pivotally connected on said ear-piece 117 and has a capability for a vibratory movement, due to the passage ot the roving between the two fingers, and it has an extension or arm 120 above its pivotal connection and laterally arranged relative thereto, on which a weight 122 is adjustably supported. Under rapid rotation of the twister-head the centrifugal force of the weight causes the finger 118 to pinch more tightly toward the iinger 116, such pinching action being lessened as the speed is lessened. By adjusting the weight farther up or down the intensity ot' the bite of the gripping jaws or iingers of the twister-head may be regulated to suit varying` kinds of yarn. This twister-head is described and claimed in an application for patent already filed by me November 21, 1896, Serial No. 612,984; but in this application I have included the twister-head supports clearly shown in Figs. 1 and 5, in which views the twisters are omitted, such twisters being shown vin said supports in certain of the other views. Said support consist of the members '123, pivotally clamped by the bolts 124 and nuts '125 on the lugs 126, secured on said supporting-bar 100, said members having the approximately semicircular yokes 127 for the rest and support therewithin ot the twisterhead bodies, the whirls 1 15 thereof having space for occupancy between the upper and lower ones of said yokes. By loosen-ing the nuts 125 the twister-head supports may have their inclination varied, soas to present the twisters axially in the proper line relative to the course of the roving and to deliver the latter directly to the nipping action of and between the drawing-rolls.
It Will be perceived that the individual twister-heads may be separately and independently removed from the supports 'therefor just described.
The vibrator 24 is as shown in the form of a light longitudinally-ranging frame located along each side of the machine between the delivery-rolls and the twisters, the same comprising upper and lower members orrods 128 128,and this vibrator has the motion imparted thereto by the connection with the lever-arm 129 thereof of the connecting-rods 130, op` erated by the eecentrics 132, Fig. 3, on the shaft 133, having, by belt 135 and pulley 136, (shown in Fig. 4,) a connectionvwhereby itis driven from the spindle driving drum N. The said vibratorhas its movements between limits more or less as indicated by dotted lines in Fig. 7, whereby it exerts a beating` action against the delivered roving. This device, however, is not herein claimed.
