MECHANISM FOR DRIVING SPlNNlNG-SPINDLES.

SPECIFICATION forming part of Letters Patent No. 465,001, dated December 15, 1891. Application filed August 5, 1891- Serial No. 401,741. (No model.)

To all whom it may concern:

Be it known that I, CONRAD SCHREPFER, of the city of Paterson, in-the county of Passaic and State of New Jersey, have invented a new and useful Improvement in Spindles for Spinning and Mechanism for Driving the Same, of which the following is a specifica tion.

My invention consists in an improvement in mechanism for driving spinning-spindles, whereby an accelerated velocity at a regular uniform rate may be obtained Without the use of driving cords or belts, as is the case with those in present use. With this arrangement of driving it is obvious that a greater amount of product is obtained of a .much superior degree of quality with regard to the equal and regular twist given to the strands than is usually obtained; also, I attain by my improvement a longer life for the spindle and its bolster and lessen the amount of power requisite to impart motion and to continue the same at high velocities by reason of the amount of contact-pressure given "to the friction-pulley of the spindle by a facewheel operated by springs attached to a driving-spider keyed to a driving-shaft located on each side of the frame; also, I gain an equality of motion to the spindles on each side of the frame by the gear-wheels and endless chains with their sprocket-wheels located on the end of the frame or system of spindles.

Another advantage I obtain is the facility with which a single spindle can be removed and replaced when so desired without stopping the frame or any of the other spindles, it being necessary only to force the face driving-wheel back on the springs and closer to the spider, which will permit the spindle to be withdrawn with ease, the springs pressing against the face-wheel with sufficient force to cause the same to drive the spindles and not forcibly enough to throw a violent pressure against the bolster.

Another advantage I obtain by my invention is dispensing with the longitudinal rails and substituting in their place transverse saddles, which are formed to receivea spindle at each extremity, and which may be easily removed and replaced by loosening a single bolt. With the rail in use at present, in the event of an accident, the whole frame has to be stopped to repair it when broken. I obtain these advantages bymeans of the mechanism illustrated in the accompanying drawings, in which- Figure 1 is a part front elevation of a single spindle in engagement. Fig. 2 is a side elevation of the same, part sectional. Fig. 3 is a part elevation of one arm of the face driving-wheel, showing hole in arm to receive the pin guiding or holding in position the tension-spring. Fig. 4 is a sectional View of part of the spindle-bolster and the driving mechanism,showing the face driving-wheel forced back to allow the withdrawal of the spindle. Fig. 5 is an elevation of. the end of a frame, showing the mechanism for communicating motion to each side and the winding-bobbins. Fig. 6 is a part front elevation of a frame, showing the driving-shafts and spindles in their relative positions.

I will now proceed to describe the construction of my invention relating to spinningspindles. Arranged on and attached to an end stand or frame a, one of which is located at each end of the machine, (and in case of ma-' chines of great length or number of spindles others are placed intermediate,) is a longitudinal bar F, on the upper edge of which are secured by suitable bolts E the transverse saddles E,with their holders D formed to receive the bolsters O of the spindles A, and which are secured by the set-bolts D. The saddles are located on the bar F at such a distance apart as to allow a sufficient space between the driving-spider L of one spindle and the bolster of another to permit freedom of access, as shown in Fig. 6. On each side of the frame a and j ournaled in bearings formed to receive them are the longitudinal drivingshafts K, to which and upon which are arranged the driving-spiders L, secured by the set-screws N firmly to the shaft K. The hub of the spider is formed at one end with two projecting lugs N to engage similar projections or lugs M on the hub of the face driving-wheel P. On the three arms of the driving-wheel I guide-pins R are located, projecting outward a sufficient distance to enter loosely into the elongated holes P, formedin the arms of the face or plate wheel P to receive them, as shown in Fig. 3. On the guidepins Rare arranged spiral springs S, one end freely on in Figs. 5 and 6.

in pressing contact against the back of the face driving-wheel P and the other against the arm of the spider L, as shown in Figs. 1, 4, and 6. The face driving-wheel P has an angular face P turned true and smooth, which face is forced against the friction-pulleyB of. the spindle A by the springs S, the wheel P being bored somewhat larger, so that the diameter of the shaft K slides freely into engagement. The friction-pulley B is preferably made of hard rubber and isturned rounding on the edge, as shown in Figs. 1 and 4. The spindle A is of the usual form and held in position by the bolster O, which is secured in the bracket E, as before described. On the extreme end of one of iheshafts K is affixed a driving-pulley a, secured by any suitable means, and on both the shafts K K close to the end of frame a are thesprocket-wheels aiwhich are both of the same diameter and fastened in any suitable manner. The peripheries of the wheels a are provided with projections to interlock with indentations in a flexible metallic endless chain f, formed with suitablelinks, which connects the two wheels a as shown On the shaft K is secured a sprocket-wheel d, of smaller diameter than the sprocket-wheels a with similar projections to engage the links of a flexible endless chain f. Located on a stud d, secured to? the side of the end frame a, and fastened by the pin (1 is a larger sprocket-wheel d, with -projections on the periphery to engage the endless chain f, as before described. Attached to and forming part of the wheel (I is a toothed pinion h, which, with the wheel d, revolves the stud d On'the stud k similarly located on the side of the end frame a, is an intermediate pinion h, which gears into the pinion h and thegear-wheels e and communicates motion to them. The gear-wheels e are keyed on the ends of shafts e, arranged longitudinally in suitable bearings on each side of the upper part of the frame a, as shown in Figs. 5 and 6. Arranged at a suitable distance apart on the shaftse are located friction-pulleys e in line vertically with the spinbins are held dies A, which engage the winding bobbins when placed in the frame. On top of frame a and extending its whole length and secured by suitable belts or, screws is a table b to hold bobbins, and to the under side of which are hung the cradles in whichthe winding-bobwhen the machine or frame is in operation, as shown in Figs. 5 and 6.

I will now proceed to describe the operation of myinvention. Motion being given by belt in the usual manner'to the pulley aflit rotates the shaft K and by means of the sprocketwheels a and the endless chain f the shaft K. The spiders L, being secured to the shafts K K by the set-screw N by means of the lug N being in juxtaposition with the lugs M of the face driving-wheels P, imparta. similar rotary motion to the wheels P,the,faces P of which being turned at a suitable angle are forced into contact with the whirls B of the spindles A by means of the springsS, located on the pins R, which form part of the spider L and impart accelerated motion to the spindle A. When any spindle or its pivotal bolster 0 requires removing, a slight pressure applied laterally to the wheel P will compress the springs S sufficiently to allow the wheel P to slide back and out of engagement with the friction pulley l3, freely on the shaft K or K. Sufficient frictional tension is given to the springs S to act against the wheel P and spider Lby closing in the spider L nearer to the Wheel P, compressing the springs S, and when adjusted securing the set-screw N. Aspacesnfficient to allow for the action of the-springs, S. is left between the ends of the lugsMand Non the platewheel P and spider L, as shown in Fig. 1. On the shaft K in front of thesprocket-wheel a is seen red by a suitable key a smaller sprocketwheel (Z which, being put in motion by the shaft K by means of the endless chain F, communicates a rotarymotion to the large sprocket-Wheel d and the pinion h, which revolve on the stud d and which are held in position by the pin 01 as shown in- Fig. 6. The pinion h imparts in its turn-motion to the idle-wheel h, which is located on the stud h and upon which it turns freely. The idlewheel h imparts on eachside ofgits. periphery motion to the gear-wheels which are secured to the end of the shafts e, which extend longitudinally the length of the'frame on each side, as shown .invFigs. 5,-and 6. Located on the shaft cat suitable distances and secured with set-screws are the pulleys e, which, being put into revolution by their shafts e, impartmotion to bobbins or other mechanism when brought intocontact with their faces in the course of themanipulation of the material being manufactured. The diameters of the geanwheels e pinion h, sprocket-wheels d and (1 and wheels a -aresuchas will secure a sufficient tension andwill remove the material being operated upon as fast as the revolving spindle S will deliver it.
