Specification of Letters Patent.

Patented May 1, 1917.

Application filed August 1, 1916. Serial No. [12,492.

To all whom it may concern:

Be it known' that I, MARTIN MCDAID, a subject of the King of Great Britain, and a resident of 56 Seafield road, Leith, in the county of Edinburgh, Scotland, have invented certain new and useful Improvements in Machines for \Vinding the Cores of (lolf Balls, of which the following is a full, clear, and exact description.

I, My invention relates to improvements in machines for winding cores of golf balls with rubber thread or similar elastic or resilient material which when covered with the usual gutta p rcha covering produces the necessary resil ency in the ball as a whole.

The present invention relates to improvements in such machines and involves an improved and simplified construction over that disclosedin my prior United States Patent No. 838,202, dated l)ecember 11th, 1906.

For a detailed description of the form of invention which I deempreferable, referonce may be had to the following specilica 25 tion and the drawings forming part thereof in which a Figure 1 is a front view of the machine;

Fig. 2 an end elevation thereof showing theright-hand end of the machine as illus- .trated in Fig. 1.

Fig 3 is a plan view thereof; and

F 4c is a cross-sectional view taken substantially on the line 4l4 of Fig. 1.

Referring to the drawings the numeral 1. indicates a suitable table or standard upon which the machine is'secured by a bolt or screw2 passing through the frame 3 of the machine. The rear of the frame 3 is pro vided withtwo upstanding lugs or cars 4. and 5 forming bearings for a main driving shaft 6. This driving shaft is provided at one end with a hand wheel 7 and also with fast and loose pulleys 8 and 9 respectively, over which a driving belt 10 may be operated. The opposite end ofthe shaft 6 has fixed thereto a main driving gear 11 which meshes with two sets of pinions T2-1?J and 145-45. The pinions '1415' are fixed respectively to a'solidshaft 16 and to a concentric tubular shaft 17, which are supported in bearingslt) and 20 fixed to to sidesof the frame 3. The opposite end of the shaft 16 has fixed thereon a roughened or kn'nrled disk or wheel 21, and the tubular shaft 17 has fixed thereon adjacent the wheel 21 a similar knurled or roughened wheel 22.

The gears 1 L and 15 respectively have different numbeis of teeth so that when driven by the gear 1 they will revolve at slightly different speeds. In the present instance the gear l-t has a smaller number of teeth than the gear 15 whereby the gear 14 will be driven at a slightly greater rate'of speed than the go: 1' 15. This will cause the knurled whees 21, and to revolve at corresponding r: tes of speed respectively, the wheel 21 rota ting at a slightly higher rate of speed than the wheel 22.

()n the shalt'o are pivoted a pair of. horizontally extending arms 23 and 24 which at their outer 01 d are lixed to a long tubular bearing 25. Through this bearing pass solid and tub ilar shafts 26 and 27 similar to the shafts 16 and IT. The pinion 12 isatlarhed to th: end of the solid shaft 26 and the pinion 13 to the. end of the tubular shaft '17. The opposite end of said shafts carry the knurled wheels or disks 2S and 29,1'0- spectively. The gear 12 however, is provided with a greater number of teeth than the gear 13 which causes it to rotate more slowly than lhe gear 13. the knurled wheel 28 to rotate more slowly than the lcnui led wheel 2!).

It will now be seen that since the'lmurled This will cause i wheel 21. rot: (es at substantially the same 7 position nndtr spring pressure and in correct relation to the knurled wheels by the following means: v

An arm Ell, is pivoted to the end of the machine at 30, the opposite end thereof is pivoted to tln ends of two upwardly extendinn arms 31 2 nd 32, the upper ends of each of which are in turn pivoted to the arms and 34 whose opposite ends are also pivoted on the end of the machine at 35 and 36. The

pivot betweei the arms 31 and 33 carries a small roll 31, andlthe pivot between the arms 32 and 2-H carries a small roll 38. A coil spring 39 cox meets the arms 31 and 32 and the tension thereof tends to draw the same toward each other, thereby forcing the rolls 37 and. 38 in the same direction. The rolls 37 and 38 are separated from each other by an upward movement of the tubular bear ing at by movement of the handle 40 attached thereto, the connection for this purpose is as follows The arm-24 carries a lpg 41 through which passes a pin +L2 preferably in the form of a screw to permit of ready adjustment. A. connecting link 43 is pivoted on said screw 42 and is connected at its lower end -with the arm 32 by means of the pivot 44. It will now be apparent that when the handle 40 is raised (Fig. l) the link 43 will also be raised thereby raising the arms 31 and 32 which being controlled by the pivots 30, and 36 will cause the rollers 37 and 2-38 to separate against the tension of the spring 3E). The wheels 28 and 29 being at the same time elevate? a core may betasil. inserted between the same and said rollers 37 and 38. which when the handle 40 is released will posit on the ball correctly be tween the knurled wheels 21, 28 and 29. A strand 45 of rubber thread or Similar material may be first wound for a few turns about the-core. before being inserted in the. machine. The winding is then started accurately by turning: the hand wheel 7 slowly until the winding, has progressed to a suf- .ticient point to warrant increasing the I speed. 'lherenpon the belt is shifted to the fixed pulley 8 and the machine operated un der its power until a suliicient quantity of thread has been wound upon the core. The.

.end of the thread is then secured to the ball and the same removed from the machine after whieh it may be treated by having the outer covering supplied in the usual way.

,The numeral 46 indicates a guide roll over which the thread 45 passes and 47 a. r \lin drieal grooved pin for guiding and tensionin{ the thread.

llavinr thus described this form of my invention, what i claim and desire to protect by Letters Patent is:-

1. A ball \Vllltllllg machine. con'iprising' a pair of frictionwheels adapted to contact with one side of a ball. means to hold said ball on the peripheries of said wheels. and means for rotating said wheels in the same direction at different relative constant peripl'ieral speeds.

2. A ball winding machine. comprising pairs of friction wheels adapted to contact with opposite sides of a ball, the wheels of each pair being located adjacent each other. and means for rotating the wheels of each pair at different relative peripheral speeds to turn said ball on an axis at an angle to respective axes of said wheels.

3. A ball winding machine, comprising pats of friction wheels adapted to contact with diametrically opposite sides of a ball, the wheels of each pair being located adjacent each other, and means for positively rotating the wheels of each pair at difl'erent relative peripheral speeds to turn said ball on an axis at right angles to the respective axes of said pairs of wheels.

4. A ball winding machine, comprising pairs of friction wheels adapted to contact with dianietrically opposite sides of a ball, .parallel shafts on which said wheels are car- 'ried, means connecting said shafts for rotating one wheel of each pair at the same speed, and the other wheels of each pair at greater speeds.
