METHOD AND MACHINE FOE .MAKING CORD TIRES.

Original No. 1,359,632, dated November 23, 1920, Serial No. 321,533, f led September 4,1919. Application for reissue filed April 29,

This invention relates to a methodan'd machine for making cord-tires. In the present state of development of this art, the carcass or casing for pneumatic vehicle Wheel 6 tires which encloses the inner inflatable tube is largely composed either of sheets or laminations of woven textile fabric vulcanized together, or, on the other hand, of circumforentially continuous layers of individual cords superimposed on each other, the cords of adjacent layers extending in reverse angular'directions with respectto the longitudinal axis of the tire. It has been found in practice that tire casings of the latter con struction are superior in wearing quality and give greater general satisfaction than tire casings of the textile or fabric construc- .tion. However, the method of manufacture;

of tire caszings of the latter class is simpler than the method heretofore employed in the production of cord tires. It is primarily due to the fact that known methods of manufacturing cord tires are very time-consuming and exacting in the care with which the numerous manual operations must be carried out, that such tires are relatively expensive. Generically considered, it is therefore the primary object and purpose of my present invention to provide a method of manufacturing cord tires which is relatively simple, will greatly expedite production, eliminate much of the onerous manual labor heretofore required and will, therefore, appreciably reduce the mamifacturing and selling cost of such tires. I

In one practical example of the new method I first assemble individual cords of predetermined length in parallel relation to each other, said cords being closely arranged and adhesivcly connected by a suitable rubber con'uoositum and I then form the multiplicity of assembled cords into a continuous annular layer corresponding to the cross sectionalshape of a tire. Upon the first. cord layer of this character therev is built up a succession of other cord layers similarly forinr-xl'in superposed relation until a body for the tire carcass of the desired predetermined tl'iiclcness is produced. It is also the'purpose of my present-invem tion to provide a machine for automatically.

posed cord'layers by means of a series of such machines upon a tire forming core.

Among the IIlOIQlIHPOIttLIllZ characteristics of true machine, may be mentioned asimple and novel mechanism for assembling the individual cords from a' series o-fcord rolls and automatically severing theassembled cords to obtain the desired length thereof;

.meansfor transferring the assembled cords to a cord layer mounted for radial move ment with respect to the forming core, and

an improvedconstruction of the cord layer and op erating n'ieans therefor to fold the series of cordsabout and upon the body of a tire forming core.

Another important feature of the invention resides in the provision of simple and effective means for clamping the ends of each cord layer to the core and thereby ap tion, looking ,inthe direction of arrow 9. of

For convenience of description. the machine of the present invention may be divided into several coacting sub-mechanisms and to that end the machine will be: considered as it operates in consecutively advancing the cords from their source of supply to their delivery and seating about the forming-core.

General desm'iption.Theprincipal mech anisms of my improved machine are grouped 4, about an annular forming core 10, pro

' ably arranged in a horizontal plane andhaving axial shaft 11 upstanding vertically" therethrough. Said principal mechanisms,

' because they are required to operate at all points about the circumference of said core- 10, are conveniently divided into a plurality of duplicate segmentai portions, all the segas 24 depending from table 25.

mental portions'of any one kind uniting to form a complete circumferential mechanism. For convenience of illustration said mecha nisms are shown as quadripartite, but might with equal propriety comprise more parts or possibly less. Each set of qnadripartite mechanism is a duplicate of each of the other three of its kind and all operate in unison, so that each sub-operation is carried on throughout the Whole circumference at one time. i

Motion is transmitted to the various submechanisn'is at the proper times, through shafting, gearing, cams, intermittent transmission and the like, all from mainshaft 12, Fig. 1, which, by suitable known means connected with gear. '7 but not shown, is caused to make one half rotation and stop; the

complete operative cycle of the machine taking place during one half rotation of said main shaft. Y

In describing the various sub-mechanisms of my improved -machine, the description, will be confined toone each ofthe quad-' ripartit-e elements, it being understood that such description will serve equally for the other three of the same kind.

00rd supply and gripping mechamsm.- This mechanism .is particularly shown in Figs. 8, 11, 13, 9 and 20. The cords 13, previously impregnated with a soft and sticky solutionof rubber, are received from a source of supply, not shown, but which is preferably located below floor 14, over guide rolls 15 and thence over delivery rolls 19, 20, 21 and 22, positioned and proportioned to approximately conform to the contour of fixed curved rail 23. Said delivery rolls may be supported in bearings Said table is of annular conformation and may be supported from floor 14. by suitable legs as 26. In Fig. 1 said table 25 is shown by dot and dash line only and is regarded in that figure as transparent, so as to show in full lines those parts below said table. Curved rail 23, it will be observed, is not a continu-',

, vid'ed, projecting a short distance from the inner face of said rail. For gripping the leading ends of the cords to the lower portion of the face of cord-carrier 28, clamp 29 suitably hinged for parallel movement in ears 30, depending from web'70 of arm 54, is provided. Said clamp 29 is hinged to said ears 305 by links 31, 32, and one of links 31 lift) 1 has ball-ended projection 33 thereon for en- I fixed ball-ended arm 36 and spring arm 37.

Said ball-ended arm 36 engages at suitable times spring-seated latch cam 38, pivotally mounted on the inner face of cord-carrier cam 40. Arm 37 is connected by spring 39 l with a pin outstanding from one of ears 30 and said spring acts alternately on either side of the axis of rock-shaft 35.

00rd-0awying mec7m'n'ism.This mechanism is particularly shown in Figs. 8, 9, 1O

and 16 and the description thereof will include the cutting mechanism, which oper ates directly after the cords have been pressed into the carrier. Arranged about and parallel with central shaft 11, at equal distances therefrom, are four shafts 41, 42, 43 and 44, fixed in bed-plate 45, which plate also supports central shaft 11. Directing attention particularly to shaft 41, mounted for oscillation thereon is sleeve 46, extending substantially the whole length of said shaft. Near the lower end of said sleeve is formed gear-segment 47 meshing with gear 48 turning freely on shaft 11. Fixed to the lower face of said gear 48 is bevel-gear 49 for turning therewith. Surrounding sleeve 46 and nearly co-extensive lengthwise therewith is sleeve 50, having formed thereon near its lower end gear segment 51 meshing with gear 52 turning freely on shaft 11,just above gear 48 thereon. Fixed to the upper face of gear 52 is bevel-gear 53 for turning therewith. Rotary motion is transmitted to bevel gears 49 and 53 from the main driving train of the machine by means to be hereinafterdescribed. Mounted on sleeve 50 for sliding engagement therewith is cord carrier arm 54. Said arm, while free to move lengthwise on said sleeve 50, is constrained for rotative movement therewith by key 55 in coengagement therewith.

Cord-carrier 28, of curved contour in plan view, Fig. 8, comprises in vertical section, Fig. 9, upper and lower straight portions 28 and 28", respectively, connected by a dished. midportion 28, all conforming in general profile to the profile of the cord folders 6O tliereabove. The outer face of said cord-carrier 28 is preferably provi 1 en With a series of parallel. grooves 64, Fig. 11,

from top to bottom,for the reception of the cords, one groove to a cord, and said grooves are angularly disposed insubstantial para lelism with the end profiles of said cordcarrier, Fig. 16. Also near its top and paral- 1e]. therewith, through it's grooved face is slot 67 for the reception of the cord-seven ing knives. Projecting inwardly from said cord-carrier 28, toward shaft 41 is stout stem 56 for sliding engagement within the socket portion of arm 54. Said stem is flattened on its upper face for engagement with a similar flat surface in the socket portion of arm 54 to keep said stem from turning.

For moving cord-carrier 28 toward and from shaft 41 at suitable times, sleeve 57 is slidably mounted on a reduced portion of shaft 41 and is constrained for .rotative movement with sleeve 46 by key 58 in co engagement therewith. Said sleeve 57 has arm 59 projecting laterally therefrom through suitable slots in sleeves 46 and 50 just above the hub of. arm. 54, and said slots are of sufficient length to permit armedsleeve 5759 to traverse the reduced portion of shaft 41 from the position of Fig. 9.to that of Fig. 11, and the slot in sleeve .50 is extended. circumferentially at its upper end 61, to permit the required oscillation of arm 59. For transmitting the oscillatory motion of arm 59 to produce a radial movement of cord-carrier 28 relatively to shaft 41, said carrier is provided with ears 62, between which is pivotedone end of link 63, the other end of said link being pivoted to the outer endof arm 59.

For coaction with cord-carrier 28 for seating the cords in grooves 64 of the outerface of said carrier, cord-piston 65 is provided. Said cord-piston has an operative surface contour complementary to the major part of the outer face of cord-carrier 28, except that said surface of the cord-piston is not cord-carrier is in its lower and inner position of Figs. 9, and 10, horizontally over the upper face of table 66 upstanding from bedplate 45. parted to said piston from shaft 68, connected to the main driving train by means hereinafter described. Said shaft has fixed thereto intermittent gears 71, 72 in engagement with racks 73, 74, respectively, fired to said piston. Said racks are supported for engagement with their respective gears by rolls, as 69, pivoted on legs, as 26. Said shaft 68 is rotated one revolution in anti.- clockwise direction, Figs. 9 and 10, the first half of which revolution is effective to cause the toothed portions of 71, 72 to engage the toothed portions of racks 73, 74, respectively, thus delivering said piston from the position of Fig. 9 to that of Fig. 10, the other half of which revolution is idle. The shaft then rotates a full revolution in clockwise direction, the first half idly and the second half effectively. with the toothed portions of gears 71, 72 in en- Reciprocatory movement is im-v gagement with the toothed portions of racks 73, 7 4, respectively, thereby returning piston 65 to the position of Fig. 9. In Fig. 10, said shaft 68 and gears 71, 72, while having portion of'said piston, and rotate in one horizontal planefor entrance into slot 67 across the path of the cords. The shafts of cutters 75 have gears 77, respectively, fixed thereto and are connected by intermediate gears 78. Said train of gears 77, 78 is driven from shaft 68 by the following means E Fixed to shaft 68 isintermittent gear 79, driving at certain times, through intermediate floating ear 81, small gear 80 fixed to shaft 82. Also xed to shaft- 82 is bevel gear 83 meshing with bevel gear 84 fixed to vertical shaft 85, to the upper end of which shaft is also fixed gear 86 meshing with adjacent intermediate gears 78, 78 which in turn drive cutter gears 77. Cutters 75 normally stand idle, with their overhanding eccentric portions projecting outwardly away from slot 67, Figs. 8 and 9, and those cutters must-not rotateto cut off the cords until piston-65 has seated those cords in carrier 28. However, there is no ob ect1on to saidcutters rotating idly at any other time and for convenience and in the interest of simplicity of mechanism,during the movement of piston 65 from the position of Figure 9 to'that of Figure 10, the

plain portion of the periphery of inter-' mittent gear 79, rotating in anti-clockwise direction, will engage'plain portion 81 of intermediate gear 81 and said intermediate gear 81 being held against rotation on its own axis but having planetary movement about shaft 68, will rotate gear-80 in clockwise direction, thereby causing each of cutters 75 to make about one rotation in anti-' clockwise direction and return approX1mate-' 1y to their positions, respectively, of Figs. 8 and 9." But immediately piston 65 reaches its inner position, clamping the cords against carrier 28, the toothed portion of gear 70 Fig. 10 to that of Figs. 8 and9, this operaand 14 to '18 inclusive. 'COIIIPIISQS, prlmarily, four sets of cordmoss tion will be reversed and the cutters re turned to their idle 8 and 9.

For raising the cord-carrier from the posltion of Fig. 10, after the cords have been pressed therein by piston 65 and severed by cutters 75, and after piston 65 has been retracted to the position of Figs. 9 and 11, to deliver those cords into position. to be taken by the cord-folders 60, Fig. 11, roll 87, pivotally mounted in hubs 137 of one of cars 30, engages cam 40. The oscillatory movement of arm 54 in anti-clockwise direction from the position of Figs. 8, 9 and'lO, in connection with "the movement of roll 87 angularly upward in cam 40, from the position of Fig.' 16, causes cord-carrier 28'to move upwardly in a helical path to the position of Fig. 11.

layers, indicated in a general way. by 60, each set arranged in curved formation in plan view, Figs. 1 and 15, in conformity with forming-core 10 about which they fold for delivering the cord thereon. In Fig. 1 the cord-folders are shown broken off close to their bearings, respectively. Each of said sets of cord-layers is mounted on a carriage, as 88, for reciprocation on table toward and from the forming-core 10. riage at its inner end has upstanding therefrom opposite brackets 89, 89, carrying segmental table 90 011 which are mounted bearings for a cord-layer 60. The lateral end edges of the cord-layers and of the cord pistons are disposed in parallel relation and extendat angles of other than 90 with respect to the upper and lower edges of said cord-layers and pistons. The term cordlayers as herein employed, is intended to be generic and applicable to mechanical means automatically actuated to apply or lay the cords upon the periphery of a tire forming core. As herein shown said cord layers each comprises a set of upper members and lower members 60'. The arm portions of said upper members 60 extend upwardly to the right at an angle to the horizontal line of the bearings and the arm portions of said lower members 6O extend near its axis, to conform to the cross-sectional profile of forming-core 10, and straight at its outer end to deliver the cords to the cord-end- gr'ippers 100, 101, Fig. 14.

Said car- Said arm'portions are preferably provided.

with smallpins 120 projecting from their inner faces to engage the sticky cords car tion 91 is .provided with a back rib 92, Fig.

55 tively, fixed to shaft 109 turning in opposite to ,one of which shafts 'motion is transmitted portions of those cord- folders 60, 60, at

v the opposite ends of each quadripartite section are materially wider than those folders therebetween. This is because of the space required for gearing and the like between adjacent sections of said folders. Arm por- 19, terminating in hub 93- having outstandinghorizontally from each side thereof a short shaft 94 terminating in One member 95 of a universal joint for engagement with a similar universal joint member on the end of the next adjacent short shaft 94. Said short shafts 94, extending oppositely from any one hub 93, are in axial line, but the pair of such shafts extending oppositely from the next adjacent hub 93 havetheir common axis at a slight angle to the axial line of said first mentioned pair ,to conform to the general curved arrangement of said cord-folders, Fig. 15. To provide for such angular arrangement, said universal joints are interposed as described. It will thus be seen that each of the bearings, as 96, will be bored from both ends in one horizontal plane but at a slight angle to each other. Said bearings are preferably parted on their horizontal axial plane, and the two halves of the lower box 96 may be all bolted to segmental table 90 by one bolt 98, Figs. 17 and 18. Said short shafts, 94, coupled'together by universal joints 95, terminate at their right hand ends, Figs. 15, 17 and 18, in intermeshing gear segments 99, and the upper line of said short shaftsterminates at its left hand end, Fig. 15, in universal joint 102, by which it is connected to bevel gear 103 meshing with bevel gear 104 on the end of sliding shaft 105. Bearings for bevel gears 103, 104 and the inner end of shaft 105 are carried by bracket 106 fixed to the side of one of brackets 89 of carriage 88. Near the outer end of carriage 88 and at both sides'thereof, fixed to table 25, are several upstanding bearings 110, 111, 116, 120, for shafts and gearing for reciprocat ing the carriage88, and for oscillating shaft 105 at suitable times.

For actuating carriage 88, opposite racks 107 are fixedto the upper face thereof and are engaged by gear segments 108, respecbearings 110. Said shaft 109 is coupled at its opposite ends by universal joints to other like shafts 109 by which motion is transmitted to the other three carriages 88 and by from the main driving train to be described later herein. Oscillating shaft 105 is supported at its outer end by bearing 111, in which bearing rotates bevel gear 112, through which said shaft may slide endwise and is constrained to rotation therewith by key 113. Said bevel gear 112 meshes with similar bevel gear 114 fixed .to one end of shaft 115 turning in opposite bearings 116. Also fixed to shaft 115 is gear segment 117 meshing with similar. segment 118 fixed to shaft 119 adjacently supported in bearing 120. Said shaft 119 receives its power from the main driving train.

Cord-end seating mechanism.-This mechanism is particularly shown in Figs. 2, 3, 6, 14, 15 and 21 and includes means for gripping those ends 13 and 13 of the cords projecting above and below cord- folder arms 60 and 60", respectively, Fig. 12, see also Figs. 6 and 14; and means for pressing those ends into the circumferential grooves lying between the innerboundary of the tubular portion of forming-core 10 and filler rings 121.

Forming-core 10 is made up of a plurality of section-like members preferably four in number, 10', 10", 10 and 10 Fig. 21, to permit the disassembling of said core for the removal intact of thelaid-upcords thereon. Said members have inwardly-reaching flange-portions, as 122, against the upper and lower faces of which are fastened rings 123 to hold said members in assembled con dition. Said flange-portions 122 have their inner faces slightly angled, outwardly and downwardly for snug engagement with ring 124, supported on legs 125 upstanding from bed-plate 45. After lifting core 10 from its seat on ring 124 and removing it from the machine, filler-rings 121, which may be held to their seats, respectively, by friction, may i by one, the other members of said core may be removed from within the laid-up cords. For gripping cord-ends 13 and 13 against the upper and lower'faces of filler-rings 121, cord-end- grippers 100, 101, respectively are provided. Said grippers are annular in form as to their operative faces, and terminate inwardly in suitable hubs 125, 126, respectively, slidably mounted on axial shaft 11 but prevented from turning thereon by suit-' able keys. Lower gripper 101 may be formed integral with its hub 126 and web 128. said web being provided with openings therethrough for legs 125 and other members. Upper gripper 100 is removably mounted on its web 127 by means of interrupted ring joint 129, of well-known character, Figs. 3 and 5. For actuating said grippers 100, 101 from the positions of Fig. 6 to those of Fig. 14, respectively, the following means are provided. Fixed to shaft 11 by key 130,

and resting on collar 131 of said shaft, is gear-head 132. Carried by said gear-head are opposite sets of duplicate gear trains, a description of one of which will suflice for both. Outstanding horizontally from said head 132, and spaced-equidistant in a vertical plane, are three shafts 133, 134 and 135. Shafts 133 and 135 are fixed in said'head and shaft 134 is free to turn in that head and has a second bearing 136 fixed to rin 124. Mounted for oscillation on shaft 133 is gearsegment 138 meshing with vertical rack 139 connected at its upper end at 140'to web 127 of upper gripper 100. Said rack is urged s to engagement with segment 138 by small roll 141 carried by a bracket outstanding from gear-head 132. Mounted for oscillation on shaft 134 is wide gear-segment 142, in engagement with gear-segment 138 and with rack 143 also connected, at 144, to web 127. Opposite rack 139, Fig. 3, mounted for oscillation'on shaft 135, is gear-segment 145, meshingwith segment 142 thereabove and with rack 146, connected at 147 with web 128 of gripper 101; and opposite thereto, Fig. 3, is similar rack 148 also I connected, at 149, -with said web 128, and meshing with 1 segment 142. When segments 138 and 145 are-rotated in anticlockwise direction and segment 142 is rotated is clockwise direction, gripper 100 will be caused to move upwardly and gripper 101 to move downwardly from their positions of Fig. 3 to their posit-ions of Fig. 6, respectively, and when those segments 138, 145 and 142 have their direction of rotation reversedthose grippers 100, 101 will be moved from their positions of Fig. 6 to those of Fig. 3, respectively.

For oscillating segment 142 and from it, segments 138 and 145, each one eighth turn and back again, arm 150 fixed to said segment142 has its outer end connected by link 151 to the outer end of arm 152' fixed to oscillating short shaft 153 mounted in bearings on bed-plate 45. Also fixed to said shaft 153'is arm 154 connected by link 155,

below bed-plate 45, with operative means to be described later herein. Y

For pressing ends 13 and 13 of cords 13 into the circumferential grooves between forming-core 10 and filler-rings 121 and seating in the annular pockets thereby formed, bead-rings 156, respectively, the following means "are provided. Said beadrings 156 are continuous rings, preferably of twisted wire,.to furnish the required strength for the edges of the tire or casing, which are engaged, by the wheel-rims in seating the tire on the wheel. Said beadrings are carried by upper and lower beadring-spiders 157 and saidspiders may be provided with holding-means such as pins 158, Fig. 14, projectingfrom'their faces, re

spectively, for penetrating between the wires of said bead-rings.

Upper-spider 157 is removably attached to carrier 162 by interrupted ring" joint 163, Figs. 3 and 4, and said carrier is slidably mounted on axial shaft 11 and is prevented from turning thereon by key 164. Lower spider 157 is preferably integral and is slidably mounted on axial shaft 11 and is prevented from turning thereon by key 166. Said spider 157 is provided with openings for legs 125, links 151, 172, arms 54 and such other members as may require passage v thercthrough. Fixed to opposite shafts, as 134, are two pairs of opposite eccentrics, respectively, as 159, 160. The straps of the inner eccentrics, as 159, are pivotally connected, as at 161, with the underside of upper-spider-carrier 162, and the straps of the outer eccentrics, as 160, are pivotally connected, as at 165, to lower spider 157. Said eccentrics are'sct diametrically opposite to each other and if rotated one half rotation, preferably in clockwise direction, Fig. 3, upper spider 157 will be raised and lower spider 157 will be lowered, from the positions of Fig. 3 to the positions of Fig. 4, respectively. If then said eccentrics be rotated in anti-clockwise direction back to the positions of Fig. 3, said spiders will be returned to their positions of Fig. 3. For

thus oscillating said eccentrics the follow-.

ing means are provided: Fixed to shaft 134., adjacent eccentric 159, is gear-segment 167 in engagement with gearsegment 168, of twice its radius. fixed to shaft 169 supported in fixed bearings 170 springing from table 124. Also fixed to said shaft 169 is rock arm 171 conne ted by link 172 with one arm of bell-crank 173 pivoted at 174 in a hearing upstanding from bed-plate 45. The other arm of said bell-crank 173 is connected by l nk 175 with .means for rocking bellcrank 173 and arm 171, each through a quarter turn andback again.

cient, when shaft 12 is rotated, to impartv to several short shafts oscillatory movement through the interposition of suitable arms having rolls thereon for engagement with said grooved paths. A characteristic grooved path179is shown in cam 180 and comprises alternate portions of angularly and circum ferent-ially disposed path, respectively. Shaft 181 has arm 182 fixed thereto and carries roll 183 for engagement with cam 180. Also fixed to shaft 181 is gear-segment 184 meshing with small gear 185 fixed to shaft 186. The throw of cam 180 is adapted to oscillate segment 184 in anticlockwise direction. one eighth of a revolu tion thereby in'iparting to gears 185 and 187 onefull revolution in clockwise direction and to gear 188, meshing with gear 187, one full revolution in anti-clockwise direction. Shaft 189, to which gear 188 is fixed, has also fixed thereto arm 190 carrying roll 191 for engagement with cradle 192. During the first quarter of its revolution in anticlockwise direction, roll 191 will rotate cradle 192 one quarter revolution in clockwise direction and also gear segment 193, said cradle and gear segment being both fixed to shaft 194. Gear segment-193 will therefore rotate gear 195, fixed to shaft 109, one half revolution in anti-clockwise direction, and segment 196 willengage the coacting portion of cradle 192 to hold the adjacent gearing at rest during the next two quarters of the described revolution of gear 188. Vhen gear 187 has made three quarters oi a revolution the roll in the end of its arm 197 will engage slot 198 in cradle 192-and turn that cradle and segment 193,in anticlockwise direction, whereby gear 195 and shaft 109 will be rotated one half revolution in clockwise direction back to their original positions, respectively. During this time main shaft 12 will have made one half a revolution and have stopped, thus completing one cycle. i

During the next half revolution of shaft 12 segment 184 will be rotatedin clockwise direct-ion through one eighth of a turn, thereby turning gears 185, 187 a full turn in anticlocl'rwise direction and the roll on arm 197 will rotate cradle 192 and segment 193 one quarter turn in anti-clockwise direction, the

same as before. Then roll 191, during the last quarter of its movement about shaft 189, will return cradle 192 and segment 193 in clockwise direction through a quarter turn. Thus the result on segment 193 and gear 195 is the same, no matter in which direction segment 184 moves. Adjoining gears 187 1.88 and forming one train therewith are equal gears 205, 206 each having roll-bearing arms for engagement with cradle 199 fixed to shaft 119 and which mechanism is efiicient to impart to shaft 119 a quarter turn in clockwise direction and then a quarter turn back again as already described in connection with cradle 192 and its mechanism. It will be observed. that shaft 119 will not be actuated until after shaft 100has made its half turn and stopped. This is because shaft 109 actuates the cord-layercarriage forwardly for positioning the cord-folders relatively to core 10 and thereafter shaft 119 rotates aquarter turn to move those cord-folders into embracing relation to said core.

Second cam 200, having a grooved path, not shown, similar to-the grooved path in cam 180, is efiicient, through arm 201 and the roll carried thereby, for imparting to shaft 202 an eighth of arevolution in clockwise direction and later back again, and thence to gears 203 and 208, fixed to shaft 207, one full revolution. Gear 209 equal to and meshing with gear 208 carries arm 211 and gear 208 carries arm 212. These arms have rolls for engagement with cradle 213 fixed to shaft 214, to which is also fixed large gear 215. Gear 217 fixed to shaft 68 is connected through intermediate gear 216 with gear 215 of four times its size. By this mechanism shaft 68 is rotated one full revolution in anti-clockwise direction and then back again during a half revolution of shaft 12. i

For reciprocating link 155 for imparting to bell-crank 152 a quarter turn and to lever 150 one eighth turn and back again, cam 210 and its'connected members from arm 218 to quarter of. a revolution of the cradle operating arms later than that of the mechanism operated by cam 210. This is because the cordgrippers9100, v101 operated from cam 210, must operate before bead-ring spiders 1'57, operated from cam 220.

For oscillating bevel gears 49 and 53, near the foot of axial shaft 11, the following means are provided: Meshing with bevel gear 49 is bevel pinion 225 fixed to one end of shaft-225. Near the otherend of said shaft is near 226 meshing with gear 227 on short shaft 228, on one end of which is arm 229, having a roll in engagement withcam 230 fixed to shaft 231. Said, shaft 231 is driven from shaft 12 through two pairs of miter gears and vertical shafts 232.

cashing with bevel gear 53 is bevel pinion 233, fixed to one end of short shaft-234, to the other end of which is fixed spur gear 235 connected byintermediate gear 236 with.

gear 237 fixed to one end of tubular shaft 238 having its bearing on shaft 225. To the other end of tubular shaft 238 is 'fixedgear 239, connected by intermediate gear 240 with gear 241 fixed to the end of shaft 242. Near the other end of shaft 242 is fixed gear 243 meshing with' gear 244, fixed to shaft 345 carrying arm 246 having a roll in engagement with a cam, not shown, similar to'ca-m 230-and fined to shaft 231 behind cam 230, Fig. 7.

Shafts 234; and 242 might well be one continuous shaft, dispensing with the offset rails 23, and so on, until their delivery and seating on forming-core 10 and the removal of that core from the machine. v

The leading ends of the cords are presented to the machine over rolls 19 to 22 inclusive and thence positioned over rail 23 ready to be clamped to the cord-carriers 28; Said cord-carriers, after being retracted horizontallyfrom engagement with cord-layers 60, by means of links 63, Fig. 12, are carried helically downwardly by arms 54, being guided by rolls 87 in cams 40, respectively, to the position of Fig. 13, and during that downward movement clamp; 29 lying behind the cord ends in Fig. 12 are swung upwardly by the'en'gagement of the ball-ends of arms 33 with cams 34:, respectively, and, clamp those ends against the lower portions of the faces of cord-carriers28. Said cordcarriers with the cord-ends gripped thereto continue their downward movement, drawing over rolls 19 to 22 and rails 23, sufficient lengths of cords, respectively, to reach angularly downwardly over the faces of said cord-carriers, Fig. 9. Thereupon cord-pistons move from their positions of Fig. 9 to those of Fig. 10, respectively, andpress the cords into the grooves inthe vertical portions 28 and 28 and into the dished portions 28, respectively, Fig. 10, thereby drawing over rails 23 a further portion of cords. Directly after the cord-pistons have seated the cords in the grooves of the cordcarriers, eccentric cutters 7 5 rotate effectively to sever the cords opposite slots 67 in the upper portions of cord-carriers 28, respectively. The severed cords being now firmly seated in the cord-carriers, cord-pistons 65 withdraw from the position of Fig. 10, and the cord-carriers, oscillated by arms 54 and directed upwardly by their rolls 87. incams #40, respectively, rise in helical-paths to the level of the cord-layers, respectively, Fig. 11. During this" u ward travel of said feud-carriers the ba l-ends of arms 36'engage cams 38 and swing clamps 29, respectively. from engagement with the cord lower ends and leave those clamps in position for lay the cords in parallel angular positions,

respectively, about the outer half of core 10 and lay the projecting ends 13 and 13 of the cords against the upper and lower faces of filler-rings 12], respectively, Fig. 6. It is customary and preferable to cover core l0 with a thin sheet of unvulcanized and more or less sticky rubber, not shown, before delivering the cords thereon, to provide a lining for the casing. Then cord- endgrippers 100, 101 move into engagement with said cord-ends and grip them against fillerrings 121, respectively, Fig. 14."

The cords, now being in possei'sion of the forming-core and its gripping mechanism are releasedby the cord-folders which open and are retracted with carriages 88, respectively, to the position of Fig. 11 ready to receive another increment of cords. During this retirement of cord-layers 60, bead-ringsspiders 157, having been previously supplied with bead-rings 156, respectively, deliver those bead-rings against the bight of the cords and press the cordsinto ,the annular channels adjacent the peripheries of fillerrings 121, drawing the cords tightly about core 10, as the cord-ends are pulled from the grip of end- grippers 100, 101, respectively, Fig. 3. Grippers 100, 101' and spiders 157 then retract to the positions, respectively, of Fig. 6, leaving bead-ring 156 seated in place, and the operation of laying one set of cords is completed.

Core 10, having a continuous layer of an gularly laid cords thereon with their-ends held in place by bead-rings 156 is then ready for removal fr0m-the machine. Such removal is accomplished by unlatching upper spider 157 from its carrier 162 and lifting said spider vertically ofl from the machine; 1

then upper end-gripper 100 is similarly unlatched and lifted off. This leaves core 1O free to be parted from its seat on ring 124,-from whence it may be lifted up, over weby127 and carrier 162 and so off the machine. p V

If only one layer of cords is desired, fillerrings 121 are then removed, the holding meansfor rings 123 released and those rings removed. This permits segment 10 of core 7 10 to be withdrawn and thereafter the other segmental portions of core 10, Fig. 21.

the other hand, if it is desired. to lay one or coacting'mechanism would be of cords manual labor.

. tirely more additional layers of cords as 13", Fig. 19, over the one already laid, the core is ren'iovc-d from the macihne as described but said core is not dismantled. rings 121 are removed to'provide space between the endsof the cords already laid and the outer edges of rings 123,,respectively, for the ends of the next layer of cords. F or assembling and laying said second layer 13, a machine which is a substantial duplicate of the. present one is employed, the only essential difference being that the angular inclination of the showing of Fig. 16 and the coacting parts in other figures would be reversed,

so as to lay the second layer of cords crosswise to the first layer, Fig. 19; and that cord-layer.-: 60, cord-carriers 28.and their enough larger core 10 having one layer thereon; also theoperative faces of spiders 157, instead of be'ii'ig adapted to carry bead-rings 156, would be formed to tuck' in the ends of cords 13; From the foregoing} description, [it is to accommodate the thoughtthat the subject matter of my pres ent invention will be fully understood. In the methods now employed for making cord tires, it is quite difficult to apply the individual cords in superin'lposed layers upon the coreat exactly the 'desiredangle and the necessary procedure involves considerable In contrast to this very laborious and time-consuming operation, it will be seen that my new method of mania facturing suehtires provides for the simultaneous applicationof a multiplicity of as sembled cords constituting a circumferentially continuous cord laycr,,to the tire forming core, thus insuring the application of the individual cords at exactly the same angle with relation to the core axis." By means of this method, the superimposed cord layers may be very expeditiously and accurately assembled and as the method is enperformed by. automatically operated mechanisms, it will be appreciatedthat very rapid production is possible. method I have more particularly defined in certain of the appended claims. It, will be readily recognized by those versed in this art that certain of the fundan'iental prim ciples of my present invention may possibly be used to advantage in the manufacture of tire casings largely composed of fabric lam'inations, as well as tire casings wherein the body structure is composed of superimposed .laminations each consisting of a multiplicity of parallel individual cords.

It will further bemanifest that the machine above described for carrying out my new method possesses manyynovel features. These featuresof my machine I havelike- However, filler- I circumferential layer.
