PATENT ROBERT AnnELLY, on XENIA, OHIO.

TWlNE-BALLING MACHINE.

SPECIFICATION forming part of Letters Patent No. 347,116, dated August 10, 1886.

Application filed March 11,1885. Serial No. 151E400. (No model.)

To all whom it may concern:

Be it known that 1, ROBERT A. KELLY, a citizen of the United States,residing at Xenia, in the county of Greene and State of Ohio, have invented certain new and useful Improvements in Balling Machines,of which the following is-a full, clear, and exact description, reference being had to the accompanying drawings, forming a part of this specifica--- tion.

My invention relates to that class of machines for balling twine, cords, 820., by which such twine, cord, &e., are made into balls ready for the market, and has for its object the simplification of construction, as well as the increased efficiency, of this class of machines.

The novelty of my invention will be herein set forth, and distinctly pointed out in the claims.

' In the accompanying drawings, Figure 1 is a front elevation of my improved machine. Fig. 3 is an enlarged detail view,partly in section, of one of the winding-spindles and its connections. Fig. lisa detail view of an attachment to be applied to the machine when it is desired to wind cords. Fig. 5 is an enlarged sectional detail of the differential gearing. Fig. 6 is an elevation of one of the finished balls. is an enlarged elevation, partly in section, of the indicator mechanism.

The same letters of reference are used to in dieate identical parts in all the figures.

A represents any suitable well-braced framework, to which the various parts of the machine are secured and journaled,and by which they are supported, and it may consist ofsubstantial end castings united by tie-beams securely bolted thereto. Near thebottom,and at the rear of the machine,issuitably journaled a horizontal shaft, B, upon one outer end of which are secured, side by side, theloose pulley G and tight driving-pulley D, driven from the line-shafting by a belt, E. The opposite projecting end of this shaft 13 is likewise provided with adriving-pulley, F. Keyed upon the shaft B within the frame is a beveled pinion, G, meshing with a .similar pinion, H, keyed upon a horizontal shaft, I, at right angles to the shaft B, and which, suitably journaled, extends to the front of the frame and Fig. 7-

projects therefrom to receive a small pulley, J. \Vithin the frame, and keyed upon the shaft I, is a pulley, K, from which a belt, L, extends up and over two pulleys or (lrums,M, keyed upon the flier-spindles N. These spin-' dles, which are hollow to permit the passage of the cord or twine through them, are journaled in a boX,.O, open at its bottom, and which may be integral with or set into and secured between thesidcs of the frame, and they carry upon their front ends disks P, to which the flier-arms Q are secured. Diametrically opposite the flier-arms and projecting from the face of the disk are balancing-arms R, as is usual in this class of machines. The twinecarrying spools or bobbins S are hung in a frame, T, supported upon the box 0, and are proyided with pivoted drag or brake arms, U, to prevent the twine being unwound more rapidly than is required.

In the present machine I have made provision for only two winding-spindles and two fliers; but by increasing the width of the machine as many spindles aud fliers may be employed as desired.

From the bobbins S the twine passes back and, preferably, twice around two circumfen entially-grooved pulleys,V, each in line with its respective spindle N, thence up over and preferably twice around grooved guide-pulleys \V, thence straight through the spindles N and up around the small guide-pulleys ab 0 to the outer endof the flierarms Q. By thus passing the twine twice around the pulleys V and 'W, or, which 'would be the same thing, around grooved cylinders or drums in place of pulleys, the twine would be prevented from.

slipping, and a more positive and certain driving of the shaft (1 accomplished, and whereby an indicator to show the weight of the twine put.into each set of balls can be connected to either of the shafts of the pulleys V or WV, as will be readily understood by reference to Fig. 7,where the shaft n of the pulley \V is shown extended beyond the framework, and carries at its end a worn1,'0, that meshes with a wormwheel, 1), 'upon the lower end of a vertical shaft, q, whose upper end is provided with a worm, r, that meshes with a gear-wheel, s, withinthe indicator-case L, which has upon its outer side adial with an outer row of equidistant numbers, extending from one to sixteen, to indicate ounces, and to which the ]arger hand, it, points, and also an inner row of equidistant figures, extending from one to twelve, to indicate pounds, and to which the short hand 1" points. The short hand is attached to the larger gear-wheel, 10, within the case, which meshes with the smaller pinion, :r, whereas the long hand is secured to and moves with the pinion 7 which meshes with the larger pinion, s. The size of the gears is made such that the short hand passes over but one division of space, while the long hand makes a complete revolution of the dial.

The pulleys I) c are suitably pivoted to the flier-arms, and the pulleys a are pivoted in cars proieeting from the disks P, and all of these guide-pulleys of the twine are so arranged as to guide it properly to prevent its wearing or chafing against any of the parts of the machine.

The pulleys V are keyed upon a shaft, (2', extending across the frame and projecting from one side.

The winding spindles A are constructed and applied in the following manner: Hung to the front of the frame by arms 0 is the vibrating spimllecarrier B, occupying a horizontal position across the front of the frame, and which I preferably formin the shape of a hollow U -shaped casting, as shown. The spindles A are inserted through hushed or bosscd apertures in the upper plate of the carrier, and receive upon their lower ends, after being inserted, keyed worm-wheels f. A. tie-bolt, g. is inserted from the under side through the bottom plate of the carrier and up through the spindle, where it is secured by a head or washer, 71, attached by a tapscrew or otherwise. Journaled through the ends of the carrier 13 is a shaft, 1', carrying within the carrier wormsj, which mesh with the wormavheelsj', to cause the revolution of the spimlles as the twine is being wound on them. In this manner I provide a very secure and simple support for the spindles, wherein the driving parts are housed and shielded from dust and dirt. The outer end of the shaft i7 is provided with a grooved pulley, k, either single, as shown, or in the form of a cone to permit the driving cord or belt to be changed to regulate the speed of the shaft 1; during the finishing of the balls. Pivoted, as at Z, to the rear side of the frame, is a forwardly-proiecting arm, m, carrying an adjustable weight, 11, adapted to slide thereon and be secured at any point desired. The outer end of this arm in has a lateral stud or spindle,on whichis pivoted two grooved pulleys, 0 0. A cord or strap, 1), passes down around the pulleyso oand up around a grooved conepulley, r, secured to a sleeve, 8, upon the projecting end of the shaft (Z. Keyed to the shaft (1, just outside of the cone 2-, is a drum, 1, upon two of the armsor spokes of which are loosely fitted beveled gears u it, which mesh with abeveled pinion 0, keyed upon the end of the sleeve 8. Upon the outer eml of the shaft (1 is slipped a sleeve, 10, carrying at itsinner end abeveled pinion, 3 meshing with the pinions u it, and at its outer end a pulley, O, driven by a belt, D, from the pulley F. This construction constitutes a differential gearing, as will be readily understood, the objeet of which is to cause therapidity with which the twine is fed to govern the speed of revolution of the winding-spindlesin the following manner: The shaft :5 is driven from the conepulley 1' through the medium of the cord or strap 12, and the cone-pulley is driven by the pulley C through the medium of thedifferential gearing. 1f the gears a were stationary, so as to have a revolution on their axes merely, the speed of the pulley r would -be uniform with that of the pulley 6; but as the drum i is secured to the shaft 11, so as to revolve therewith by the action of the twi ne passing through the machine, it is evident that the gears u, in addition to rotating on their axes, revolve around the gears 3 and '0 and in the direction of revolution of the gear r; hence the speed of the gear 12 aml conei' varies with the speed of the drum 1, so that the faster the drum 1, travels the slower will be the speed of the cone 9, and consequently of the shaft i and winding spindles A. This change in the speed of revolution of the winding-spindles is rendered necessary to secure a proper winding of the balls by the gradual increase in the size of the balls, and as the balls grow larger they take off the twine more rapidly, and thereby increase the speed of the pulleys V and shaft (1 to effect the decrease in the speed of the winding-spindles, as before stated, and thus the machine is remlered automaticin this particular, as in others to be presently explained.

To cause the spindle-carrier with its spindles to so vibrate as to present the spindles properly to the twine being wound on them, I secure an arm, E, to the lower side of the carrier B, which arm carries at its lower inner extremity a roller, F, that bears against a cam-disk, G, of the shape shown, which is keyed upon a horizontal shaft, 11, suitably journaled in the frame. A belt, 1, passes from the pulley J around a pulley,J", fastened, as will be hereinafter explained, upon a shaft, K,whose inner end is provided with a worm, L, meshing with a worm-wheel, M, upon the shaft 11. In this manner motion is communicated from the shaft 13 through the medium of the shaft I, pulleys J and J,and other parts described, to the shaft 1[, and consequently to the cam, which is shown at its normal position of rest in Fig. 2, just before or at the starting of the machine,and which makes one complete revolution during the complete wi ndingofthe balls upon thespindles, aml then stops to permit the removal of the balls. This cam in its revolution forces out the S] )ll1(ll0-Cillll(31' B through the medium of the arm 19', and

causes the winding-spindles, whose position of inclination at the starting of the balls is shown in Fig. 2, to gradually assume a more horizontal position, and then to return again to their first position as the winding of the balls is completed. From this vibration of the spindle-carrier B will be seen the necessity for having the weighted arm m and pulleys o, for as the carrier travels up or down the pulleys 0 rise and fall, and at all times maintain the proper tension of the driving-strap 1).

To cause the machine to stop automatically when the balls are finished and the cam has made an entire revolution, I employ the following mechanism: Two horizontal rods, N O, extend across the machine and have slid ing bearings in uprights I suitably secured to the frame-work. These rods, which are preferably round in section, are held from turning bya clam p-brace, a, Fig. 1. The rod N carries at its projecting end an adjustable perforated head, It, from which the beltshipper rod S, embracing the belt E, extends and is secured by a set-screw, b. Coiled around the rod N is a spring, 0, which bears at one end against one of the uprights, I and at the other against a shoulder or swell upon the rod N. A lever, U,pivoted, as at d, at the back of the frame, extends forward tothe front of the machine, and is provided with an operating-handle, c. This lever U is con nected by a slot and pin to the rod N, so that by taking hold of the handle 6 the rod can be drawn back to compress the spring 0 and to cause the belt E to be shipped to the drivingpulley. To hold it when thus shifted the for- .ward end of the lever U rests upon the top of a standard, V, at the front of the machine,

provided with stop'shoulders f, to one of which is pivoted a latch, g, that catches over and engagessthe lever U when the belt has been shifted to the fight pulley. A stud or pin, h, is so arranged upon the cam G that when said caln has just about completed its revolution the pin it comes in contact with the projecting end of and lifts the latch thereby freeing the lever U and the spring 0, which, recoiling, forces out the rods N O and consequently the shipper, thereby throwing the belt onto the loose pulley and stopping the machine. To restart the machine, itis only necessary to draw back the lever U until it is engaged by the' latch g, whereupon the belt will be shifted to the tight pulley, as before described.

Ifit is desired to stop the machine-lat any time before the completion of the winding of the balls, it is only necessary to trip the latch g and the spring 0 will cause the belt to be shifted to the loose pulley, and to do this the more readily I provide an operating-handle, i, which projects forward from the rear end of the latch g, as shown.

The arrows in the different figures will show the direction of revolution of the various parts, .and it will be understood that the rod 0 is only employed to prevent the turning of the rod N through the medium of the clampbraee a.

\Vhen it is desired to ball cord, I provide an attachment to the machine, which is shown in Fig. 4, which can be readily put onto or taken off the machine, as the case requires. It consists of any suitable frame, j, carrying grooved rollers 7t" and rope-covered stretching and rubbing rollers Z, which are rex'olved in directions opposite to the line of travel of the cord by a belt, an, arranged as shown, and driven from a pulley (not 'shown) upon the shaft B. The cord leaving the pulleys l, by which it is stretched and its projecting fibers removed, passes over a small grooved guide-pulley, m, and thence around the pulley V on its way to the winding-spindles.

Having thus fully described my invention, I claim- 1. The combination, with the winding-spindles, the winding-spindle driving-shaft connected to said spindles by Wormgearing, and a shaft revolved by the passage of the twine through the machine, of the differential gearing, substantially-as described, connected to said shaft, and a cord or belt connecting said differential gearing and the spindle-driving shaft, whereby the speed at which the twine is fed onto the spindles determines and regulates the speed of said spindles, substantially as described.
