ALBERT G. BREWER, OF NATIOK, MASSACHUSETTS, ASSIGNOR TO HARRISON HARWOOD AND ROBERT W. HARWOOD, OF NATIGK, MASSACHUSETTS, A FIRM.
. BALL WINDING AND ROLLING MACHINE.
To all whom it may concern:
Be it known that I, ALBERT Gr. BRIWVER', of Natick, in the county of Middlesex and State of Massachusetts, have invented cer' tain new and useful Improvements in Ball Winding and Rolling Machines, of which the following is a specification.
This invention relates to machines for forming playing balls, and particularly base balls, by winding a continuous filament of yarn or string to form a gradually increas ing spherical body, a hemispherical cup being employed in which the ball of yarn is formed by the rotation of the incipient ball by contact therewith of a winding wheel having a roughened periphery opposed to the cavity of the cup, and so arranged relatively to the cup that as the ball increases in size, it recedes gradually from the axis of the winding wheel, means being employed to impart a lateral movement to the cup as the winding action progresses.
The invention has for its object to provide certain improvements in a ball winding machine of this character looking to the more perfect formation of the yarn into a ball, and the variation of the speed of winding as the ball increases in size.
Of the accompanying drawings forming a part of this specification, Figure 1 represents a top plan view of a ball winding machine embodying my invention. Fig. 2 rep resents a front elevation of the same. Fig. 3 represents an elevation of parts of the machine, and a section of other parts on line 33 of Fig. 1. Fig. 4 represents a section on line 4-4 of Fig. 1, and an elevation of parts at the left of said line. Fig. 5 represents a section on line 5-5 of Fig. 1, and an elevation of parts at the right of said line.
The same reference characters indicate the same parts in all the figures.
The supporting frame of the machine, as here shown, comprises a bed or base12, having bearings 13 in which is journaled the driving shaft 14, to which motion may be applied by a driving belt running on a pulley 15 affixed to said shaft.
16 represents the frictional winding wheel having a roughened periphery which may be provided by striking up spurs on the metallic surface of the wheel,or in any other suit-able way, the object being to provide a periphery adapted to engage the surface of Specification of Letters Patent.

Serial No. 443,678.
a ball of yarn and impart a rotary movement thereto. The ball-f rniing cup is here shown as a block 17 provided with a hen'iispherical cavity 18, and detachably secured to a carrier 19, which is rnovably supported by a horizontal table 20 Mixed to the frame of the machine, the carrier being provided with anti-frictional -balls 21. movable upon the table. The cup may be secured to the car rier by means of brackets 22 al'lixed to the I,
carrier, and thumb screws 23 passing through slots in the vertical arms of the brackets, and entering the back of the cup. The carrier and cup are pressed yieldingly toward the winding wheel 16 by means of a spring 24 bearing at one end against a bell crank lever 25, the other end of the spring bearing upon a washer 26, which is adjustably supported on a screw-threaded rod 27 by a thumb nut 28, which permits an adjustment of the 14 washer 26 to vary the tension of the Splflllg 24. The bell crank lever is pivoted at 29 to a fixed ear on the base 12, and one of its arms is connected by a rod 30 with a treadle, not shown. The lever 25 is normally held by a spring 31 in the position shown in Figs. 1 and 4 with the cup retracted from the winding wheel. The spring 31 is here shown as interposed between the lower arm of the lever 25 and the bed 12, although in practice :3.
the spring would be applied to the treadle at a point below the bed. When the rod 30 is depressed by the treadle, the lever 25 projects the cup toward the winding wheel, the
lever being movable independently of the W the carrier cup has provisions for varying the speed of the movements, so that the reciprocating movement may be relatively slow at the commencement of the winding operation, and may increase in rapidity as the size of the ball increases. includes a frictional driving wheel 32 affixed to the driving shaft 14:, and a frictional driven member 33 adapted to engage one side of the disk 32, and movable laterally of said disk, so that it may engage the disk at 119:
Said mechanism any desired distance from the axis of the driving shaft. The driven member 33 is here shown as a leather belt which loosely encircles a horizontal drum 34, which is journaled in bearings in the upright arms 35 of bell crank levers, which are mounted to oscillate on a stud 36 supported by ears 37 afiixed to the base 12. The upper ends of the lever arms are connected by a cross bar 38. The said bell crank levers have horizontal arms 39 which are connected by a cross bar 40. A spring 41 connected with the cross bar 40, and with an arm 42 atlixed to the supporting base, yieldingly holds the lever arms 35 in the position shown in Figs. 1, 2 and 3, with the driven member 33 out of contact with the friction disk 32.
43 represents a lever fulcrumed on the stud 36. and having av longer arm engaged with the treadle rod 30, and wit-h the lower arm of the lever 25, and a shorter arm having a slot 44 which engages a stud 45 on one of the horizontal lever arms 39. hen the treadle rod 30 is depressed, the longer arm of the lever 43 is also depressed, and its short-er arm is raised, forcing the lower end of the slot 44 against the stud 45, thus causing the lever arms 35 to swing inwardly toward the friction disk 32, and bringing the driven member 33 in contact with said disk, so that the driven member is rotated and imparts rotation to the drum 34 by its frictional contact with the latter.
46 represents a. cam which is affixed to one end of the drum 34, and when said drum 34, and when said drum is rotated, acts on is rotated, acts on a lever 47 which is mounted to oscillate on the stud 36.
48 represents a bent rod having a horizont-al arm or portion mounted to slide longitudinally in fixed guides 49, and provided with bent arms 50, the upper ends of which are arranged in close proximity to the opposite ends of the carrier 19.
51 represents a spring interposed between a fixed support and a nut 52 secured to the rod 48, said spring having a tendency to move the rod in the direction indicated by the arrow in Fig. 2. The vertical arm of the bent rod is pivoted at 53 to one of the lever arms 47; consequently, the spring 51 acts through the rod 48 to hold the lever arms 47 against the cam 46, the cam and spring acting conjointly to oscillate the lever arms 47 and reciprocate the rod 48, thus causing the arms 50 to engage the carrier 19 and reciprocate the latter in the same direction, the carrier being thus moved cross-wise of the periphery of the winding wheel. The movement thus imparted to the carrier and the cup thereon is not exactly rectilinear, but is made somewhat irregular by studs 54 aflixed to the carrier, and projecting rearwardly therefrom into slots 55 in fixed ears 56 on the supporting frame.
The ends of the slots form stops for the studs 54, the slots being of such length that they arrest the studs before the end of the movement imparted to the carrier by the means above described, so that the carrier has a slight swinging movement as it approaches the end of its travel in each direction. The compound movement thus imparted to the carrier is found desirable in causing the proper distribution of the yarn on the periphery of the ball, and preventing the yarn from accumulating in ridges on any particular part of the ball.
The driven member 33 is ITIOVilblO lengthwise of the pulley 34, which is elongated, as shown in Figs. 1 and 5, means being employed to shift the position of the driven member 33 relatively to the axis of the disk 32, provision being thus made for varying the speed of the rcciprmating movements imparted, as above described, to the carrier and cup, it being desirable to make said movements relatively slow at the commencement of the winding operation. when the ball is relatively small, and to increase the speed of said movements as the size of the ball increases. The means here shown for shifting the position of the driven member comprise, first, a slidable rod 57 which is adapted to slide in suitable guides supported by the lever arms 35', and secondly, a collar 59 atlixed to the rod 57 and provided with end flanges (it) which engage the edges of the driven member 33, so that when the rod 57 is moved endwise, the driven incinbcr 33 will be corrcspmidingly moved on the pulley 34. The rod 57 is provided with a suitable hand wheel (31.
(32 represents a cam which is atlixed to a hub 63 (Fig. mounted in a frictional clamp or bearing (34. which is carried by one of the lovers 35, and is adapted to be turned therein to vary the position of the cam (32 which is eccentric to said hub. the object of the cam (32 being to furnish a variable stop for the movement of the lever 47 in the direction indicated by the arrow in Fig. I). provision being thus made for varying the throw of the rod 48, and of the carrier ltl. and the cup thereon. The hub 63 is provided with a squared orifice through which the rod 57 passes. and in which it is adapted to slide, the rod being correspondingly formed. so that when it is turned. it will also turn the hub 63 and cam (32, thus adjusting the latter. The aim is in the path in which the lever 47 oscillates, and therefore constitutes a stop limiting the movement of said lever in one direction. ,.\ccidental turning of the rod 57, hub (ii-3, and cam (32 is prevented by the friction hearing (it. which, as shown in Fig. 3, is composed of two parts adapted to be con'ipressed on the hub (33 by screws (35. One of the parts or members of the friction bearing (34 is proltltl vided with a shank 66 which is attached by a bolt 67 to the cross bar 38 connecting the levers 35. A set screw 68 engaged with the shank 66 enters a slot 69 in the shank 66, and bears on the bolt 67 to maintain the friction bearing 64 at the desired height.
7 0 represents a tension spring between one end of which and a fixed bearing 71 the yarn passes from a suitable source of supply through a guide orifice 72 in the cup 17. The tension spring is provided with a notch '73 which guides the yarn to the point where tension is applied to it. The tension is regulated by an adjusting screw 74;
75 represents a pulley which guides the yarn to the cup.
The operation of the machine is as fol-' lows :-The core or nucleus of the ball is inserted in the cup and the carrier 19 is moved forward toward the winding wheel until the latter suitably engages the side of the core which projects from the cup, this operation being caused. by the depression of the treadle rod 30 which moves the lever 43 in the direction required to swing the levers 35 toward the friction wheel 32, thus causing the driven member 33 to engage said friction wheel. A reciprocating motion is thus imparted to the rod 48 and through the arms 50 to the cup 18 and its carrier, the speed of the reciprocating movement of the cup being determined by the distance of the driven member 33 from the axis of the disk 32. At the commencement of the operation the friction member 33 is relatively near the center of the disk, said member being drawn outwardly toward the periphery of the disk from time to time, as the size of the ball increases. The ball is continuously rotated by the winding wheel so long as it is maintained in contact with the latter, the position of the ball being changed by the described irregular movement imparted to the cup, so that the size of the ball increases uniformly over its entire surface. When the ball has attained the desired size, the operator releases the treadle, whereupon the spring 31 swings the vertical arm of the lever 35 outwardly and retracts the carrier and cup from the winding wheel.
The levers and 39 constitute an oscillatory carrier for the driven member 33 and the pulley 34:, said carrier and the cup 17 being movable simultaneously by the lever 25, which acts to move the cup toward the winding wheel 16, and the driven member 33 toward the driving wheel 32.
I claim:
1. In a ball-winding machine, the combination of a winding wheel, a cup movable relatively to the wheel, means for reciprocating the cup crosswise of the periphery of the wheel, and means for imparting swinging movements to the cup while it is being reciprocated.
2.
