The shafts 18 are provided outside of the bear-- ings 17 with sprocket-wheels 85 over which runs 'a sprocket-chain 86 communicating motion from one roller 19 to the other.

The `rollers 19 are caused to rotate and thereby revolve a tire mounted thereon by .the following mechanism: Mounted on one of the shafts 18, preferably the left onein Fig. 2 and the front one in Fig. 1, is a bevel gear 21 arranged to mesh with a bevel- ,pinion 22 Splined on a vertical Vshaft 23 mounted in suitable bearings in the base 3 and head 4 of 4thestandard 2. The carriage 15 isprovided with a laterally-projecting apertured lug24 which receives the shaft 23 Vand which serves to support the beveled pinion 22 and 'to cause its vertical which forms the driving member o a clutch,'

a driven 'member 32 is splined on the shaft 28 and is adapted to engage therewith when shifted through the medium of a lever 33 fulcrumed at 34 on the bracket 30 and operated by a pull rod 35 the handle of which is positioned within ready access of the operator when standing at the left of the machine i'n Fig. 2.

It will be noted that lwhen the vertical position of the carriage 15 has been `secured, the member 32 of the clutch is shift- Y edinto clutching relation with the pulley 31 and a motion is communicated to the latter thrpu h the medium of any instrumentality such or instance as a belt, the rollers 19 will be rotated in vunison lin the same direction and. consequently revolve a core 2() mounted thereon. Mounted on the upper faces of the heads 4 of the standards 1 and 2 is anA inverted U-shaped frame provided with two downwardly-extending legs 36 and 37 resting on the heads f4 and secured thereto by any suitable mechanism. In order to sustain the upper portion of a tire or other annular object mountedon the rollers 19 during the revolution thereof, guidin mechanism which is shown in detail in Flg. 7, is provided. This mechanism consists of a horizontal threaded shaft 38'bearin a hand wheel 39 by whichit is lrevolved an is supported in a threaded bearing 40 so that as the shaft 38 is rotated it is shifted horizontally, Secured tothe inner end of the shaft 38 is a. volw/41 bearing a guiding roller 42 sizes.

preferably inclined at an angle with respect tothe U-shaped frame. Fixedly secured to the inner portionA of the shaft38 is an immovable arm 43 to the u er end of which is pivotally connected a 11n 44. Positioned 70 on the opposite side of the' opening inclosed .by the U-shaped frame is a bearing 45 in portionof the tire 20 during' its revolu ol'f" on the rollers 19 and -by 'thismaflsf'tle vdistance between thelrollers 42 and'may bechanged'to accommodate tires of vdifferent serve as a guide and support for-g he'up er 35 n L. '90 W ndz'ng mechanism-Briefly, 'the winding mechanism embodies a pair of broken-A annuli revolving on offset axes of revolution and constituting a shuttle or a bobbin-car rier. In detail, there is provided on the 95 front face of the U-shaped frame in Fi l,

a plurality of flanged rollers 51 arrange at the angles of an imaginary hexagon so that an annulus may be revolved on their periph-n eries. Also secured on the front face of the det U-shaped frame is a condseries ofroll: ers 52 arranged eccentrically vvithrespect to the 'series .of rollers 51. Mounted on the peripheries of the rollers 51 is a broken an, .gz-. nulus 53pm-vided nea'r the boker'rportion'- *los with counterweights 54'and also rovidedl with a series' of apertures in w ichra'e mounted wrist-pins 55.-` The frontfac'e the annulus 53 1s also provided with a pht I rality of horizontally-projecting pins 84 for 11o a: purpose to belater `lescribved. Y

The axisv of the annulus 53-is 'at 57. Rev' olubly mounted on the peripheries of the rollers 52 is a second annulus 58 theaxis' of which is at 59. This annulus is also provided "11i`$ with a plurality of apertures inwhich are mounted wrist-pins 60 a.nd connecting"t he. wrist-pins 55 in the ann'ulus 53 With. the ad# jacent wrist-'pins 60 in the annulus 58 .are,

links G1 vfor a purpose to be later describedig'12`0' The two annu'li are adapted to constitute a' shuttle'and are arranged to revolve in unison inthe same direction during' both the wiid'- ing and the unyvinding operations and the revolutionpof these annuli-is effected by the 125 following mechan'em: Y In fafsuitable bearin extending through the U-shaped frame 36 1s a shaft 62 bearing near its rear end a sprocket wheel 63 which receives a sprocket chain 64 running overa 130 sprocket wheel 65 tlxedly secured on the Ymunicated from the driving shaft Q8 to the vshaft 62 the annulus`53 will be revolved.

A b1 't-stretcher- 7 0 is employed for 1naintaining tensiony on ,the belt 69 but as this beltstretcher may be of any ordinary construction a detailed description thereof is believed to be unnecessary. The countcrweights 54 are positioned on the annulus 52 to counterbalance the bobbin and its carrier, a detailed description of which follows:

Bobbi'n. und carriera-The mechanism, by

- which .a strip of material is wound onto and unwound from a tire or other object, em-

.bodies a bobbncarrier and a bobbin so ar` rangedfthat the bobbin is permitted to rotate on its own axis, protected hy a .tension device, during the placement of a strip. of material and arranged to be held against independent rotation on its own axis during the unwinding ofa strip of material from an object.'

In detail, annulus 53 opposite to the. broken portion is prpvided with a transverse` opening constitntlngy a bearing in which is mounted a shaft l71 4'formed integral with a crank -72'positioned rearwardly ofthe and nulus 53 and between it and the annulus 58.

The latter' annulus is also provided with an opening to receive a wrist-pin 73 on the opposite end of the crank 72 so that as the annuli revolve in unison the position of the l crankar'm 72 will always be vertical vand this is also true of the links 6l which connect the wrist- pins 55 and 60. B this arrange -Utation .thereon would always normally maintainits relative position during its orbital movement about the tire 20. The shaft 71 in front of the annulus 53 is provided With aA hub 74 from which projects a boss 75 provided with a laterali extending.,y arm 76. The portion 82 of t e shaft 71 which projects forwardly from the boss 74 bears a rotatable drum 77 around which is a band-brake 78 one end of Which is anchored at 79, (see'Figs. l and 6) to the arm 76 and the opposite end of the band is secured to a threaded shaft 80 extending through a suitable aperture in the arm 76 to receive a thumb nut 80 by which the bandbrake 7-8 is contracted for tensionin or en tircly preventing the revolution of t e bobbin-carrier 77. 0n the front face of the bobbin-carricr are a pair of pins 8l adapted to be received in suitably-formed apertures in the rear face of the,bobbin 82 for detachably connecting' the` bobbin 8" to the bobbin-carrier and inducing or preventing rotation of one `with respect tothe other. The bobbin is held on the port-ion 82 of the shaft 71 through the `medium of a nut 83 held in position by a bayonet joint, `or any other preferable or approved means so that the bobbin may be readily placed on the shaft-,wand removed therefrom.

` The placement of a. stri i ot material on an object sucl as atire is illustrated in detail in Fig. 3, and in this instance the stri of material rs'seeured to the riglvside o the tire in this ti ure and the shuttle embodying Mthegtwo annu i is revolved in the direction of the arrow and a suitable degree of tension is imposed on the bobbin carrier through the medium of thebandbrake 78 to place the required amount of tension on the strip during its lacement. During the orbital movement o the bobbin 82 about the tire 9.0 the latter, of course, is revolved on its own axis throu h the mechanism 'already described and t e revolution of the bobbin about the tire is maintained until a sutii'cient has been laced on the tire.

Supply y `relative position, of the crank will be maintained atall times.

1fl it is desired to `unwind a previously placed strip from the tire the band-brake is .tightened sullicientlyto prevent. independen t rotation ofthe bobbur and its carrier and the shuttle is revolved in the same direction as it is during the placement ot a strip, but ther strip is taken from theoppo- 'site side of the tire,'or to be more exact, the Atire is reversed in position and as the bobbin orbitally revolves about the tire in the direction of the arrow, the strip of material is Wound u on the bobbin, see Fig. 4. WVhen it is esired toimpose an additional tension upon the strip durmg its placements, then strip is carried around one or more of the pins 84 on the annulus 53,

From the foregoing it will be seen that the shuttle is rotated in the same direction both for the placement of a strip. of material and its removal from an object and that it is not necessary to reverse the revolution of the shuttle for the two oherations, the only requirement being that tlie position of the tire or other object be reversed during the unwinding of a strip of material therefrom.
