SPINDLE-DRIVING DEVICE FOR SPINNING-MACHINES.

SPECIFICATION forming part of Letters Patent No. 415,827, dated November 26, 1889. pplicatiou filed June 4, 1888. Serial No. V275,930. (No model.)

To all whom it may concern.-

Be it known that I, JOSEPH E. TYNAN, of Paterson, in the county of Passaic and State of New Jersey, have invented an Improvement in Spindle-Driving Devices for Spinning-Machines, of which the following is a specification.

My invention is especially designed for use in that class of machinery in which either a single thread is twisted and wound or two threads are twisted, doubled, and retwisted and wound; but my said invention may be used in other kinds of silk -twisting machinery and also in machinery for twisting cotton or other thread.

Vhere the spindles of a spinning-machine are each driven by a separate belt, as is generallythe case, said spindles are not always all driven at the same rate of speed; hence there is inequality in the twist given to the threads. This irregularity of speed of the spindles is caused by the slip of the belts upon the spindles and driving-drum' and by the varying tension of the belts.

An endless belt has passed along between two rows of pulleys to drive them simultaneously, as in English Patent No.1,938 (old law) and United States Patent No. L1,215 to W. Baxter, and spindles for spinning have been driven by such pulleys, and in some instances several spindles or groups of spindles with pulleys have been driven by one endless belt; but in case of one thread breaking it either had to be joined while running or else all the spindles had to be stopped, and where stop mechanisms have been provided for each group of spindles they have either had separate belts or else were driven by frictionwheels that in practice are found to be more irregular than belts.

In my improvements I employ one endless belt to drive numerous groups of supply and lay-up spindles, the belt passing between the pulleys of each group, so as to drive the layup spindles in the reverse direction to the supply-spindles, and I combine with this a drop-bar-stop mechanism to each group, so

from being moved by the contact therewith of the traveling belt, and in carrying out this invention I cause the pulleys to press against the belt by the force of springs and swing' them away by a positive action.

In the drawings, Figure 1 is a plan view showing my improvement applied to a silk doubling and twisting machine, only a portion of the machine being shown and the spindles being represented without their spools orl bobbins. Fig. 2 is an elevation of the parts shown in Fig. l, with the spools or bobbins upon the spindle. Fig. 3 is a sectional elevation at the line Qc of Fig. 2, the parts being shown in larger size. Fig. 4 is a seotional plan at the line y 'y of Fig. 3. Fig. 5 is a rear view of the lower end of the dropbar, showing also the ends of the spindle-carriers operated by said drop-bar.

A A are the frames ofthe machine, and B the spindle-rail supported by said frames A A.

In Figs. I, 2, 3, and 4 the spindles are shown as arranged in groups of three, as in Letters Patent No. 364,783, granted to me June 14, 1887. The spindles 3 3 carry the spools 6 6, that supply the single thread, and these threads, after being twisted, are laid together and wound upon the spool 8 of the spindle 5.

9 is the ring-rail carrying the ring-travelers, and this rail may be actuated in any manner for laying up the threads upon the spools 8.

The spindles 5 are supported and revolve in bolsters a, secured to the rail B, (see Fig. 3,) and said holsters are ranged in a straight line lengthwise ot the machine. The spindles 3.3 are in a line parallel with the spindles 5; but their bolsters or bearings f are mounted upon supports or carriers c c, pivoted at to projecting portions of the rail B.

E is the endless belt for giving motion to the two rows of spindles. This belt is carried by the drums F G upon shafts 13 14, respectively supported in bearings I-I II upon the fra-me A, and motion is given to the belt by a belt from the driving-shaft of the machine passing around a pulley 16 upon the shaft 14. The endless belt in its travel passes between the two rows of spindles 3 3 and 5, and said spindles are rotated by the contact of the edges of the belt with the pulleys a a and fi fi upon the spindles. The arrows upon Fig. l indicate the direction of travel ot' the IOO ' lof belt E and the direction of rotationof the spindles 3 8 and 5, the spindles 3 3 rotating in the opposite direction to that of the spindles 5, so as to give the proper twist to the single and doubled threads.

In order to keep the endless belt in Contact with all the spindles of the two rows, I mount the spindles 3 3 upon pivoted carriers c c, as aforesaid, and I provide a helical spring hfor each pair of spindle-carriers, as shown in Fig. 4, which springs draw the longer arms of said carriers toward each other and bring the pulleys a a of said spindles 3 3 against one edge of the endless belt, thereby forcing the opposite edge of therbelt against the pulleys t1' of the spindles 5 andinsuringuniformity of contact of the belt with all the pulleys of the two rows of spindles. The longer arms of the spindle-carriers c c extend beyond the rear of the rail B and receive between them the double inclined end ot' the link or drop-bar D, which drop-bar D is to be connected at its upper end to the lever of a stop-motion device, preferably such as that shown in my application for patent, Serial No. 256,728, filed December 2, 1887, it being understood that there is a drop-bar for each group of spindles 3 3 and 5. lWhen a drop-bar of any group of spindles falls from a thread breaking or otherwise, the inclined end of said drop-bar acts upon the longer arms of said spindle-carriers c c and causes said carriers to swing upon their pivots c, andthe pulleys a a of that group of spindles are moved away from the belt and brought into contact with the spring-brakes l Z, which arrest their rotation. At the same time the spindle 5 is stopped by the arms m of the dropbar coming into contact with the top surface of the pulley z' of said spindle 5. When the drop-bar is raised by the attendant after the broken thread has been joined, the pulley t of the spindle 5 is released and the spring 7L swings the spindle-carriers so as to move the pulleys a a away from the brakeslland into contact with the edge of the belt E, .and the group of spindles is again put into motion by said belt. By thisimprovement all the spindles of each row will be driven at the same rate of speed, as there is a constant and uniform pressure of the pulleys againstthe belt. The drop-bar D is guided in its movementby the pin d, projecting from the end of the oiltube (l5 and passing into a slot in said dropbar.

It is necessary that the endless belt should travel in a straight line, or nearly so. If the endless belt is not sufficiently stiff, the pressure of the pulleys a a against said belt at` places where there are no idler-pulleys opposite said pulleys a a might bend said belt and cause its edges to travel in undulatory lines, and the spindles 3 3 would be moving out of line of each other, which would interfere with the spinning operation. To prevent this I stift'en the endless belt by a band 't of sheet metal secured to the belts by rivets.

This metal baud may be between the two thicknesses of leather of the belt,it the beltis of two thicknesses; or it maybe applied to the outer surface of thebelt, as shown. In either case it prevents the belt stretching and stiftcns it so that the belt will travel in a straight line and thereby keep all the spindles of the single row in line with each other.

I claim as my inventionl.
