SPlNNlNG-MULE SPECIFICATION forming part of Letters Patent No. 408,540, dated August 6, 1889.
Application filed January 12, 1889. Serial No. 296,186, (No model.) Patented in France September 6, 1888, No. 192,815, and
' in Belgium September 6,1888, No. 83,158.
To all whom it may concern:
Be it known that I, OSCAR S HIMMEL, a subject of the King of Saxony, residing at Chemnitz, in the Kingdom of Saxony, Germany, have invented new and useful Improvements in the Driving-Gear of Self-Actors, (for which I have obtained Letters Patent in France September 6, 1888, No. 192,815, and in Belgium September 6, 1888,, No. 83,158,) whereof thefollowing is a specification.
My invention relates to the driving-gear of the carriages of spinning-mules employed in spinning carded yarn, the said gear comprising a run-out pulley with two portions of different diameters; and the invention consists in features of novelty hereinafter described with reference to the accompanying drawings, and particularly pointed out in the claims.
In the annexed drawings, Figure 1 shows in sectional side elevation at rope-pulley of the present construction, together with a part of its driving-gear.
cording to my invention. Fig. 4 is a sectional side View of a part thereof. Fig. 4 Fig. 5 is a skele. ton view of a self-actor provided with the im-. proved gear, and Fig. 6 a plan corresponding,
shows another part in plan.
to Fig. 5.
In self-actors for carded yarn the carriage.
carrying the spindles is driven during its run out with decreasing speed. During the first, part of the said run in which roving is sup:
plied, the carriage is caused to move as fast as possible in order to shorten this period,
which is unavailing to the spinning opera tion proper, whereas during the second part,
in which the roving that had been supplied.
is drawn out and twisted, the carriage moves slowly. These different motions are ob-- tained by means of a pulley, (run-out pulley,)
such as the one shown in Figs. 1 and 2 and marked by the letter S. The said pulley has helical grooves, which serve to receive the.
Fig. 2 is a front view of the pulley. Fig. 3 is a sectional vlew of a pulley and its driving-gear carried out ac:
and a spiral which connects the grooves of the said portions together. In order to avoid a breakage of the roving while being drawn out, this operation must be carried out gently by causing the carriage to run Very slowly at the time. A considerable difference of diameter of the pulley portions L and V is therefore required, which renders it necessary to make the diameter of the portion L Very large and the portion V of such small size that it is hardly possible to pass a shaft of sufficient thickness through the same, the pulleys being for this reason mounted on the ends of shafts reduced in diameter, as shown by Fig. 1. Moreover,it follows from the great difference in the diameters of the pulley portions L and V that the connecting spiral, which, in order to avoid shocks must not be made too steep, will have alength corresponding to a considerable portion of the run-of the carriage, and this is another source of inconvenience. For the purpose of always keeping the roving-threads between the delivering-rollers and the spindles stretched, the operation of drawing out the said threads should commence, and consequently the stoppage of the delivering-rollers takes place, when the carriage-rope passes over at the point a, Fig. 2, from the pulley portionL to the spiral; but as from the great length of the spiral the speed of the carriage decreases but slowly the drawing out of the threads would in such case ensue too rapidly, so that they would break. For this reason the delivering-rollers are not stopped until the carriage-rope has passed by a certain length on the spiralsay to the point b-the consequence thereof being, however, that the speed of the carriage meanwhile decreases to less than the peripherical speed of the rollers and that the threads become slack, wherefrom an uneven yarn results. For the purpose of obviatin g these inconveniences I reduce the difference between the diameters of the two portions of the rope-pulley by making the larger portion smaller and the smaller portion larger than heretofore, while at the same time '1 impart to the pulley two different speeds in succession, the speed at which it rotates when the rope runs on the larger pulley portion being by so much greater than in the present machines as that the usual high speed of the carriage is maintained at the time roving is supplied, whereas the speed of the pulley is comparatively less when the rope runs on the portion of smaller diametert'. e., at the time the delivering-rollers are at rest and the reving is drawn out and twisted. In consequence of the said reduction of the difference of the diameters of the pulley portions the spiral that connects the said portions together becomes shorter, so that the change from the greater speed of carriage to the lower speed ensues more rapidly, while, nevertheless, this change takes.place gently enough, as the slope or angular incline of the spiral is not altered. This mode of driving the pulley presents the additional advantage that different proportions of speeds of the carriage may be obtained with the same pulley by changing the gear-wheels that produce either of the said speeds.
In the improved pulley-drivingmechanism shown by Fig. 3 the ordinary driving-gear of the pulley is connected to the roving-delivering roller by a differential wheel-work in such manner that as soon as the said roller is stopped the pulley will rotate more slowly.
Z and Z are two spur-wheels, such as are now in use in self-actors. As shown by Figs. 5 and (3, these wheels are driven from the main shaft A through the medium of the wheels 0 p q. The wheel Z has fixed to it the change-wheel .2, which gears with the wheel R, being the present pulley-driving wheel, (see Fig. 1,) while-the wheel Z is connected by the toothed coupling K with the shaft 0 of the roving-delivering roller 0. The wheel R, heretofore directly connected to the pulley-shaft \V by the toothed coupling K, as in Fig. 1, is loose on the sleeve g of the latter, while the shaft IV carries, loosely rotating thereon, the spur-wheel R, which gears with the pinion 0', keyed to the shaft 0.
The two wheels R and R are provided with the respective bevel-wheel teeth It and 7a, with which gears the bevel-wheel U, arranged to turn freely on a pin Z, fixed radially in the disk T, the said disk being keyed upon the end of the sleeve 9, so that its rotation will be transmitted by means of the coupling K to the shaft \V, and consequently to the ropepulleys secured to the same.
If the two wheels R and R are driven simultaneously, as is the case when the roller 0 rotates 1'. e., when roving is deliveredthe disk T will rotate with a speed depending upon the difference of velocity of the wheels R and R, the wheel R being larger than R and the pinion 2 larger than 7'. The shaft \V and the pulley S will consequently assume a certain speed, during which the carriage-rope runs on the large portion of the pulley S. If thereupon the roller 0 is stopped by the disengagement of the coupling K, the wheel R remains at rest and the disk T, together with the shaft XV, immediately assumes a lower speed. About at the* same time the carriage-rope passes onto the spiral of the pulley S, the said pulley being keyed on the shaft \V in the position requisite therefor.
In order to maintain the wheel R with certainty at rest after the roller 0 has been disengaged from its driving-gear, a brake or other equivalent device may be applied to either of the parts R or (J. In Figs. 3 and 4 an arrangement is represented in which a brake-pulley Bis keyed on the shaft 0 of the roller, the said pulley having a brake-strap passing aroundit, which is connected with its respective ends to the fixed pin 0 and to the upper end of the lever e, pivoted to the pin 0, so that when the lever e is turned in the direction of the arrow 9%, Fig. 4, the brakestrap is drawn tight and the shaft C hold fast. The motion of the lever e is brought about by means of a wedge it, which is pushed between the lower end of the lever and a fixed abutment n. This wedge forms the end of a rod 2, movable lengthwise and connected to the lower end of the disengaginglever 71 of the coupling K, the said lever being operated, as in the present machines, by a spring f and a rotating tappet E and maintained in its position subsequent to the action of the latter by apawl i. If for the purpose of disconnecting the roller C the pawl i is raised by means of a counter, as usual, the spring f pulls the top end of the lever to the left, (relatively to the drawings,) so that at the same time the coupling K is disengaged the wedge 11. is moved to the right. If at the commencement of a new run-out of the carriage the coupling K is re-engaged by the tappet E, the wedge 10 is retracted and the roller C and wheel R are released again.
In consequence of the reduction in size of the portion L and increase of the portion V of the run-out pulleys, these pulleys may be united with the counter-pulleys S and keyed on a shaft WV, having a thickness proportionate to the strains to which it is exposed and passing through the pulleys, as shown by Fig. 3. This affords another advantage relatively to the parallel motion of the carriage. For producing this parallelism of motion of the carriages of self-actors for spinning carded yarn various more or less complicated eonstructions have heretofore been employed, as, for the reasons stated, it is impossible to pass a shaft of the requisite thickness through pulleys of the present proportions. The new pul leys being, however, adapted to have such shaft passed through them may be employed for guiding the carriage parallel, in like manner as the cylindrical run-out pulleys of selfactors for spinning cotton. For this purpose the run-out shaft \V, driven at diiferentspeeds, as described, is arranged to extend from one end of the machine to the other, as shown by Figs. 5 and 6. Two, three, or more combined pulleys S S are placed thereon, and all the pulleys S are connected to the carriage directly by ropes 8, while the pulleys S are con- ICC IlO
nected thereto by ropes s, passing over guide: rollers r. The run-out shaft and the carriageguiding shaft of the present self-actors are thus united into one, and the construction is considerably simplified.
I claim as my invention 1. In self-actors, the combination, with the shaft W, the run-out pulley S, fixed thereon and having two portions of different diameters, the roller 0, the shaft 0, and the spurwheels Z Z, of the pinion z, fixed to the wheel Z, the disengaging coupling; K, the parts whereof are connected, respectively, to the shaft 0 and the Wheel Z, the pinionr, keyed 011 the shaft 0, and a differential wheel-work gearing with the pinions .2 and a" and connected to the shaft W, substantially as specified.
2. In self-actors, the combination, with the shaft IV, the run-out pulley S, fixed thereon and having two portions of different diameters, the roller 0, the shaft 0, and the spurwheels Z Z, of the pinion z, fixed to the wheel Z, the disengaging-couplin g K, the parts whereof are connected, respectively, to the shaft C and the wheel Z, the pinion a", keyed 011 the shaft 0', and a diiferential wheel-work comprising the sleeve g, connected to the shaft W, the loose spur-wheels R and R, gearing with the respective pinionsz and r and having the bevel-Wheel teeth k 70, the disk T, keyed to the sleeve 9, and the bevel-wheel U, pivoted to the disk T and gearing with the teeth It and k, substantially as set forth.
3. In self-actors, the combination of the shaft WV,two or more pulleys S S fixed thereon, each having two portions of diiferent diameters, the roller 0, the shaft 0, the spur-wheels Z Z, the pinion z, the disengaging-coupling K, the pinion r, a differential wheel-work gearing with the pinions z and r and connected to the shaft WV, ropes ss, connecting the said pulleys with the carriage, and guide-rollers r, substantially as described.
In testimony whereof I have hereunto set my hand in the presence of two subscribing witnesses.
