` ly applicable for applying covers to the cores of endlessbelts.

An object of the invention is to provide a machine for applying covers to elongate articles which shall becapable of .winding the cover circumferentially of the article and simultaneously folding its edges laterally.

In one of its practicalembodiments, the invention includes a driven disc disposed adjacent a plurality of adjustable'rollers, and in the. plane thereof, which rollers are adapted to retain a belt core drivenv by engagement with a peripheral portion of the disc. A strip of adhesive fabric to be applied to the core asa cover therefor is fed between'the latter and the disc, whilestitching rollers and folding devices successively apply portions of the cover to the core. Any number of layers of covering material may be appliedin this manner merely by continuing the winding thereof on the core.V

For a better understanding of the invention, reference may now be had to the accompanying drawings, forminga part of the specification, of which: f f

As best shown by Fig. 3, the aforesaid bracket supports a motor 24 that is provided with a shaft 25 having a clutch member 26 slidably keyed to its end, as indicated at 27. A second clutch member 30, disposed adjacent the clutch member 26 and adapted to be engaged therewith. is rigidly mounted on a shaft 31 that is rotatably supported in

bearings

32 and 33 in a housing 34 mounted on the frame plate 23. v

The clutch member 26, on its face adjacent thev motor, is provided with a groove38, in which the forked end 39 of a bell crank 40` pivoted intermediate its ends as indicated at 41 to the bracket 22, is disposed. The opposite end 42 of the bell crank is pivotally connected to a vertically depending rod 44, that projects'through an apertured plate 45 secured to the bracket. An adjustable spring 46 encircles the rod 44 and abuts Ithe lower of a pair of nuts 47 threaded on the rod 44 and the plate 45 at its opposite ends. Consequently, the spring tends to move the rod 44 and the arm 42 upwardly, in which event the.

clutch member 26 and the clutch member 30 are separated. Upward movement of the rod is limited by a pair of nuts 48 threaded thereon below the plate 45, one of which rod is in its upper- Referring again to Fig. 1, the lower end of Vthe rod 44 is connected by a turn buckle 49 to a rod 50, pivoted at its lower end 51 to a crank 52, which is keyedl on a shaft 53 rotatably supported in a pair of brackets 54 bolted to the base 20. A treadle 55, provided on the shaft 53 at its end opposite the arm 52, facilitates operation of the clutch member 26. Normally, the

clutch members

26 and 30 are disengaged, but upon downward movement of the treadle 55, the member 26 is brought into engagement with the .'clutchi member30, and the motor shaft 25 yand the shaft 31'are operatively connected' Vtogether'.

Anelongate vertically'idisposed barV 106, secured by Vbolts 107 and` 108 to an oHset-ljr'io'rtiony 105 of the bracket 97, has lan offset andi'ncl'ined apertured block 110 at its upperend", in .which an opening' 109,inclined downwardly toward the'plate 23,'is 1 formed.

Api-11111 is secured in the opening 109l VWAsbest shown b vrFigfS, *the pin 1111.*is

Vprovided with a circular Vhead 113, 'at' its Lovverend, which isdisposed in'a recess 115 ,in the'lower endof a vconical rollervr 114 '-romountedl onthe pin. The roller'is resiliently `maintained against the headV 113 by a'spring 116 abutting at its upper endA a Vcollarj117 secured by aset screw118 tothe pin, and at its lower end a thrust bearing119 abutting the roller.

' The frame' plate 23,'.oppos1te the 1 06 and'onits side adj acentthereto, is provided 'with a vertically extending bar 125 ,secured thereto by bolts 124. This bar'h'as a block 126 at its upper end inclined oppositely to theblock 110 on the bar 106 and having an opening 128 inclined oppositely to 'the'open ing 109 in the latter. A pin 127, disposed in the opening 128 and secured therein by a set screw 123, is'provided'on its lower end with a resiliently mounted conical Aroller 1-29 and a spring mounting assembly similar to that employed on the pin 109. The rollers 114 a'nd'129 are'so mountedrthat'xtheir conical surfaces' substantially coincide, respectively,

with. the.verticalvplanesin which `the sides "ot the disc'71 are disposed, but this relation ofthe rollers/and discmay be varied by adjusting the pins'111 and 127 by their respective set screws' 112 and 123".

- :A bar 130, secured against' the outer fend of a stud 145threaded into the outer side ot the base 79 'of the block 76 by afscrevv .133-

projectingthroughthe bar` and vengaging an n opening in the outer end of the stud, is provided with openingsv 131 and 132 on opposite sides ofthe screw 133, which loosely receive-the'fsleeve 95 and the bolt 94. Thisbar hasv an odset arm' 134 atitsupperendwhich is disposed above the disc' 71 transversely of lthe plane thereof. and vadj a'centV the rollers 114landv129.V N f i.

A laterally extending rod 135, `proj eating atone endithrough the'tramev plate 23 directly' beneathfthe block 76, is securedthereto by nuts 136Qand 137' on the rodthat abuts opposite'si'des ofthe-frame plate.V 'This rod,

at its vouter end, projects through an apen tured bloclry 138 which is' secured `theretoxby 'a'set screw 139.. The block'138` alsois aperturedto're'ceive va 'vertically' disposed rod 141, which is secured therein by a set screw 140. Thelatt'er rod has an offset portion 14 at its lower end extendingparallel to the :rod'f'135,"`which is-'disposed transversely to Vthe lplaneof butv below the disc 71. 4Inad- -diti'on,ithe ext-ended portion L1.42'is reversely bent to provide a loop 143. f f

'An upright'150'securedi by bolts 151 to the upper 'end of the-frame plateV 23 on the side thereof adj acent-y the block 76, has in turn an offset portion 152A at its upper endto 'which avertically eXtendinggui'd-emember 154 is `secured by bolts 153 (Figs. land 7 This lguide member has an elongate vertically dis-v '.posedlsl'ot l155 in which Va roller mechanism "156 is 'adjustably mounted.l Thel latter mechanism'includes a stud 157 having a reyduced'po'rtion 158 adjacent its inner endl projectingsthrough' the 'slot 155', and Va shoulder 159 abutting'theguide member 154 at the sidesof the slot.l *Thes'tud isv adjustably securedto the guidemember by'a screw 160 having va head 163, extending through a collar'16-1 adjacentthe'guide member', and threaded4 into the reduced portion '158fof the stud.V 1n lo'rderto adjust the position. ot the studl and the." guide 'memberya'V pin 162 or other suitable instrument, is inserted 'into mitting movement of thel stud and collar relative to the guide member, `whereafter it istightened'to secure the studin its newly yadjusted position. f

The stud 157 yis provided with a reduced portion 165 outwardlyof the shoulder 159. and other successively reduced portions 1.66 and 167, the latter of which terminates in a threaded end 1.68. A collar 169, rotatably supported on the reduced portion 165, is provided with a chordally disposed aperture 170, through which an elongate rod 171 slidably projects. The reduced portion 166 of the stud in turn supports the inner race of a ball bearing 173 which is enclosed within a roller housing 174, retained in position by a bushing 175 on the reduced portion 167 of the stud and a `washer 176 against which a nut 177 on the threaded end 168 of the stud abuts.

As illustrated best by Fig. 1, an arm 183, pivoted at 184 to the lower portion of the frame plate 23, extends upwardly in the plane of the disc 71 and is provided with an arcuate upper portion 185V of slightly greater curvature than thatof the disc. Normally, the arcuate portion is disposed concentrically to the disc, but spaced a small distancetherefrom and its free end rests the seat 85 provided in the offset portion 84 of the block 76.

` An angle bracket 188 (Fig. 6) ,having an arm 189 provided with an elongate slot 190, is adjustably secured to the aforementioned arcuate portion 185 by a bolt 191 that projects through a locking washer 192,the slot 190,and is threaded into such arcuate portion. The bracket also includes a cylindrical offset portion 194 having a threaded opening 195 in its outer end that receives the threaded end of the bolt 196, the head, ofwhich is provided with a longitudinally disposed threaded aperture 197. This bolt supports an oscillatory collar 199 disposed againstthe offset 194, and a roller 200 between its head and the collar. A threaded opening 198 inthe collar 199 receives the threaded end ofthe aforementioned rod 171 that has previously beenl described as slidably passing through the collar 69 mounted on the guide member 154. A plate 201, disposed on the periphery of the collar, in spaced relation to the opening 198 and secured to the collar by screws 202, is provided with a threaded opening 204 that receives the threaded end of a radially. extendiugfguide rodv 203. lThe side of the collar 199, next to the roller 200, is provided with a threaded opening 206, extending parallel to the axis'of the collar, in which an angle guide rod 205 is secured by a set screw 207. Thisv rod. at its outer end, extends parallel'to the rod 203, but is disposed on they side of the roller 200 opposite thereto.

A bar 208 is adjustably secured to the head of the bolt 196 by a second bolt 209 which projects through the bar and is threaded into the aperture 197 in the first mentioned bolt. This bar is apertured at its outer end to receive a pin 211 secured at one end in the aperture by a set screw 210. The other end extends toward the roller 200 and is providedl with a reduced portion 212 rotatably supporting a roller 214 maintained thereon by a nut 215 on the end of the pin. The pin 211 also is disposed parallel to the bolt 196 and the roller 214 rotates thereupon in the plane of the roller 200. It is apparent that the position of the roller 214 may be varied relative to the roller 200 by varying the positions of the bar 208 and the pin 21.1.

A second angle bracket 225 (Fig. 4) spaced relative to the bracket 188, is rigidly secured by bolts 226 to the arcuate portion 185 of the arm 183 and, like the bracket 188, is provided with an offset portion 228 having a threaded opening 229 in its outer end that receives a bolt 231. This bolt rotatably supports a roller 230. A sleeve 238, adjacent the bracket 225 above the offset portion 228, is rotatably secured to the arcuate portion 185 of the arm 183 by a bolt 239 which is threaded into an aperture-240 in the arm. The sleeve 238, in turn, has an integral offset arm 242 adjacent its outer end, which is apertured as indicated at 244 (Fig. 5), to receive an elongate stud bolty 245. The end of the latter adjacent the arcuate portion 185 of the arm 183,

projects throughV an eye 247v of a vertically i disponed eye-bolt 248 and has a washer 249 disposed outwardly of the eye which is engaged by a nut 253. The eye-bolt 248 projects at its upper end through an apertured arm portion 256 of an angle bar 257, which has a depending arm 259 secured by bolts 260 to the arcuaterportion 185. Above the arm 256, the eye-bolt has a nut 263 adjustably secured thereon which is adapted to limit the downward movement of. the eye-bolt, while beneath the arm a spring 266 is coniined between the arm, and a nut 265 adj ustably secured on the bolt.

The bolt 245, on the side of the arm 242 opposite the eye-bolt 248, rotatably projects through

legs

269 and 270 of a U-shape block 268, between which legs it rotatably supports

rollers

275 and 276. These rollers are of sufficient diameter that they project slightly below the base or bottom side of the block. The bolt 245 is retained in the block by a head 280 engaging the leg 270.

The legl 270 of the block 268 has on its lower side a bar 285 pivoted thereto by means of a vertically extending bolt 283, which projects through the bar and engages the block. In order to retain the bolt 283 in position, but loose enough to permit pivotal movement of. the bar 285 thereon, the upper end there 'of has a screw 282 threaded therein, which Aso abuts the'upper surface of the'l'eg270 of the block. The barv285 (Fig. 4) hase. portion 286 projecting substantially'I parallel tothe n Y I vbolt'245 toward the rollers 275 and'27 6, which istwisted adjacent the outer side of the roller l 27.5, asindicated at287, to provide a vertically. disposedlip 288,.which lip isnormally'disposedl in\sub'stantially` the plane ofthe outer sideof the last mentioned roller. j-'This bar normally ,is maintained vin this positionby a rod 294pivotally secured tothe bar,`asin dicated at" 292, and which hasV a normally disposed threadedy portion 296extending through an apertured plate 299 secured lby ,lbolts-301tothe sideA of the block 268. V Between the'bracket 299 and the pivoted end of the rod 294, the portion 296has a nut 302 thereoin'to limit the movement ofthe bar 285 toward therollers 275and 27 6, while on yits ,Qouter endv it isprovided with anut 303. A

j thereupon.v A spring 319is disposed in encircling relation to therod between thelug 314 and a nut 318 threaded on the lower portion ofthe rod. y b j The arcuatey portion 185 of the arm` 183 also supports a sleeve 330, disposed between f V.the sleeve 238and the roller 200, which is. -740 retained on the arm by a bolt 331 projecting through the sleeve and engaging a threaded aperture 333 in Vthe arm. Adjacent its outer end, the sleeve is providedwith an. integral voliiset arm 334 that terminatesin an apertured portionsimilar to the arm 242previously described-' A block 337, (Fig. 1) of lU-shape like the block 268,i's pivotally secured to this arm by an elongate stud bolt I33'6,which sup- Y Vports pair of rollers 345 similar to the

rollers

275 and 276 between thellegs of the'V block. An eye-bolt l338, mounted on the outer end v oi:V the stud bolt, is secured thereon by a nut 340 threaded von the outer end of the bolt. Like the eye-bolt 248, the eye-bolt 338 extends upwardly and projects through a bracket 350 (Fig. 1') whichhas a depending portion 351 secured by bolts 352 to ythe arcuate arm portion 185.l A nuty 354 on the upper end of the eye bolt is adaptedV to limit downward movement thereof relative to the bracket 350, while between the 'bracket and a nut 355 a spring` 357 isfencircled about the bolt.

l Y An arm 370 of an angle bracket 360 is searm 371 of thebracket has a'rod 363 rpivotally secured thereto, as indicated at 362. This rod,in turn, `projects through-a lug-365 Vintegral with the` sleeveY 330.A 1.The outer end of the rod engages-a nut 367, whereas 'aresilient spring 369 thereon is confined between a nut-368 and the lug'365.

A bar 380,-',rigidlysecured tothe lower side of 'the legv ofthe block.v adjacent the armA 334, is provided withan `arcuate portion 381 that extends oppositelyto the arcuate portion V286 ofthetirst mentioned barY 285,.and'inter mediate of its ends is twisted,as indicated at 382, to provide a verticallyv disposed lip 383, positioned" inthe -planejof the outer side of the roller adj-acent this leg of the block 343. j

Anadjustable bar 390 is pivotally connected at its opposite ends Y391 and ..393 to the arm 183 and toy a `hand Vlever 392, respectively. Thehand lever ispivotally connected, as in-v dicated at v394, to the frame plate 23. An eX- tended portion'396ofthe hand leverfon the side of the pivot 394 opposite the pivot 393 is adapted to engage a lug 395Jsecured by a bolt 397 to the frame plate when the hand leveris in the' position shown by Fig. 1.*v The arm 183 normally is Iresiliently 'maintained in the position shown by this ligurebiy a spring 400, which engages a recessed collar 401, retained bya bolt 402 on the arm1183, and at its oppositeend encir-cles a lug 405, integral with .the boss 68." VIt is apparent when therhand lever 392 is moved counter-clockwise from its position shown by Fig.,11, that as soon i as the rod 390 moves above the pivot 394, the

spring 400 begins to act to move thearm 183 quickly to its inoperative position. However, with the rod390 disposed'below the pivot 394, the spring 400 firmly maintains the eX- tended portion, 396 of the handlever against thel lug 395 on'` the frame plate, andthus the arm 183 in its operative position.

In the operation ofthe apparatus,the endlesscore of, a belt 410 is trained aboutl the rollers`174, 200 and 230 and between the .guide

rods

203 and 205 disposed adjacent the roller 200. Also the core is' disposed between the

lips

288 and 283 of the resiliently mounted bar285 and the rigid bar 380, respectively.

VThereafter the arm 183lis moved to its operative position by the hand lever 392, wherein the core will be disposed against a portion ot' the periphery of the disc 71. Thus when the motor 24 is energizedthe disc 71 drives the core overl the rollers about which it is'trained. In order to firmly contactthe core with a substantial portion of the 'disc 71, the roller 214 feo' Vmay be moved toward the disc by adjustment of the bolt 209, as will be readily understood. With the corein this position, it is disposed between the resilient lconicalrollers'114 and 129 with the conicalsurfaces of therollers engaging the sides of the core.v

'In applying an adhesive cover 411 to the f Vcured byV bolts'361 on the upperV surface of j core, it initially is trained through the loop 11:.;

. the. block 337, `whereas a vertically extending 143, over the `sleeve 9.5,thebolt 94 and the bar 184, and then stitched to the outer periphery of -the core adjacent ythe roller 200. -As the core is movedby the disc 71, the cover is pulled between the conical rollers 114 and 129, and the latter stitches the side portions of the cover against the sidesof .the core. ,Simultaneously with this operation, the lip 383 and the arcuate portion 382 of the bar 380 guide one edge portion of the cover over the inner periphery of the core.y Thereafter, thel lip 288 and the arcuate portion 287 ofthe bar 285 guide the other edge portion of the cover over the inner periphery of the core and also over the first mentioned edge portion of the cover. Itis apparent that any ldesired number of thicknessesof cover may be applied to the core by continuing the windingofan elongate strip thereover. 1

From the foregoing description, it is apparent that a. machine has been provided by means of which a cover may be applied to the vcoreof an endless belt or similar article by circumferentially winding a cover about the core and simultaneously folding it laterally thereabout. Itis apparent also that as many layers of cover ymay be applied to the core of the beltor such article as ymay be desired. By reason ofthe adjustabilityof the roller '174, the resiliency of the conical rollers 114 and 129,and the resiliencyof the

bars

285 and 380, it is apparent that 'covers may beapplied to various lengths and sizes of belts.

yAlthough I have illustrated only one form which the invention -may assume and have described that form in detail, it'will be apparent to those skilled in the art that the invention is not so limited but that various modifications may be made therein without departing from the spirit of the invention or from the scope of the appended claims.
