FLEXIBLE ROLLER Application filed November 22,1929; Serial No. 409,025.

The application of a skin coatofrubber, paint, orany other plastic compound or substance on cordor close, woven cottoniahric or.=similar material, is accomplished by passingthefabric through two rollsone ofwhich is provided with a thin wall of compound to be applied to thefabric, and the pressure necessaryfor this application ofthe compound to the fabric is produced through the medium OftlLtl llI'd :roller asis well known in the art.

Tlhrough the medium ofi feeding the compound between thisthird roller and the said one. roller of the. first mentioned pair of rollers atithesame time the fabric or other matcrial ispassed between said pair ot rollers, and through the application of proper; pressure, a skin coat of the compound Will'be readily pickedup by the fabric, or, other material passing betvveensaid pair of rollers and thus '20 thematcrial' will be coated with thethin layer of the compound such as rubber, paint or other. plastic substance.

The chief function of said third roller which 1S termed the cushion or flex1ble. roller is mallow the passing ofithe fabric or material :ofiva-rying gauge, (within aitolerance of from .001 tofl005 inches) without crushing or, distortingthe fabric, yet; at the same time having suflic-ient pressure to apply theicoat.

properly and in the ma uuerabove referred-tot From the foregoing itswillb'e seen that the third rollermust be fieXible,yet at the same time of sufiicientstrength as to be capable of a thin coat' of rubber, paint or other plastic compound or substance on cord or close woven cottonafabric asin the production of rubber tires otlier rubberized goods, oil cloths and '45 cushion roller which will be fully capable for fulfilling the essential of a third roller as are used for this purpose and which roller will possess certain other highly desirable qualities as to render the same capable of carrying out these necessary qualities in a supplying the neededpressure for applying n anner much,more eflicicnt than has heretofore, been accomplished,

The above and other. objects and advantages of the, invention will be apparentfrom astudy ofthe, following description, taken in connection witl ntllfi accol'npanying draw ings, wherein l igure lisaside elevation oi, a flexible or cushion roller embodying t he, features oi my invention.v

Figure 2 is a fragmentary dctailscctional view thereof;

Figure 3, is an cndiview thereof.-

Figure l is a transverse SOCtlOlIiIIZVlQV therethrough.

Figure 5, is a fragmentary detail elevational view of one ofithe clamping discs.

Figurefi is a perspective view of one of the steel, rings forming the surface of the flexible roller.

With reference more in detail to the drawings, it; will be scenthat my invention comprises a core 5 formcdatopposite ends thereof with reduced ,end portions6 forming journals, which journals (i-in turntcrminate in reduced ter-minals'i, and asshown to advantage in Eigurefi, these end projections Tare PTOVldOClllVdth suitable keyways; 8 whereby ball gears (not shown), for grinding the roller may be keyed; to said projections. Arranged on the core 5 aslshown to advantage in Figure 2 is a sleeve 9 of a length corresponding to the length of the core 5, and this sleeve 9 is formed; of any suitable compound flHdlW-lllClL sleeve 9 may be of any thicknessofjdepthas to fitbeneath for which the roller is intended Arranged on the sleeve 9 isa series-of metallic discs or rings lO'forming the outer or contactingsurface oi": thefiexibleroller. These metallic rings or diseslO have an interior diameter correspondingito theexteriondiameter, of the sleeve 9 and may be-slipped upon to be arranged thereon in end to end relation, the rings 10 being suflicient in ,nulnbe as to extend from one end to the other ofthe roll as shown to advantage inFigure 2.

At each end; ofthe core 5- anddisposed thereagainst; are clamping rings 11 l;1, which clampingrings are mounted, on the journals 6 and bear against the end of the sleeve 9 and the rings 10 on the ends of the core through the medium of which clamping rings the series of rings or discs 10 will be clamped axially together on the sleeve of the core. r

c To preventcreasing of the rings or discs- 10 on the core 5, said rings on their inner periphery are provided with a plurality of.

circumfercntially spaced notches 12 preferably of the shape shown in Figure 6, These notches 12 provide seats for elongated lockin bars 13, which bars 13 in cross section are of a shape corresponding tothe shape of the 1 notches 12. These locking bars 13 fit in the notches or seats 12 and extend longitudinally across the outer face of the sleeve 9 as shown to advantage in Figure 4. The ends of the lock bars 13 are receivable in suitably shaped recesses or sockets 1 1 formed on the inner ends or faces of the "clamping rings 11 as shown to advantage in Figure 2. i

It is also to be noted that the clamping rings 1111 adjacent their inner periphery are provided with a series of circumferentially spaced bolts 16 through which openings are passed headed bolts 17 are threaded into the comb for securing-and retaining the clamping position as is also shown to advantage in'Figure 2. The retaining rods 13 arranged within the seats 12 will retain the rings 10 against relative displacement with respect to one another, and these members 13 having their ends receivable in the suitably formed openings 14: formed in the clamping rings 11 will also retain the said rings 10 againstslippage or rotative movement relative to the composition sleeve 9 as is apparent. I The sleeve 9 is formed of a suitable composition designed to afford the necessary flexibility, and in view of the foregoing, it will be readily appreciated that a roller of this character will he barel stron enou h to i apply the necessary and desired pressure for accomplishing the purpose for which it is designed, and at the'same time preventing crushing, distorting, cutting or otherwise renderingdefective any and all material being socoated in machines for this purpose and equipped with a roller embodying the features of'the present invention.

Even though I have herein shown and I described the preferred embodiment of my invention, it is to be understood that the same issusceptible to some changes fully eomprchended by the spirit of the invention as herein described, and the scope of the appended claims. I v 1 I-Iavmg thus described my invention, what I wish to claim as new 1s i 1. In a device of the character described,
