Detailed description,

Referring tothe drawings, the machine as here shown comprises a frame 10 from which rises a pair of multiple-bearing brackets 11, 12 upon which are mounted

respective ring winders

13, 14, upon the inner faces of the brackets, the winders being swiveled upon respectivel hollow, radially slotted

stub shafts

13, 14, (Figs. 3. 4 and 5), so that non-rotating work-manipulating devices mounted upon and adjacent their `faces which are the nearer to the middle of the machine.

In general, with a few exceptions, odd nu merals are used herein for parts at the lefthand side of the machine and even numerals for parts at the right-hand side.

Each of the winders is formed with a radial, Work-receiving slot. 15 or 16, the slot being registrable with the radial slot. 17 or 18, formed in the winders shaft and each Winder is formed on its periphery with a set of gear teeth 19 or 2() which are ineshed with two idler pinions 21. 28 or 24. the duplication of pinions assuring proper drive notwithstanding the radial slot in the Winder. The pinions "21 and Q2 are secured upon a shaft Q5 and thepinions 23 and 2l upon a shaft 26. and the pinions :22. 2-1 of the righthand Winder 14 are ineshed with a gear 27 which is loosely journalcd upon a shaft 2S and is provided with .a hub pinion Qi) adapted to be intermittently driven by a nini may be y tilated gear .30 which is secured upon the main drive shaft 31` of the machine, upon the inner side of the bearing bracket 12.

Secured upon the drive shaft 31 outside of the bracket 12 is a large driving gear 32 meshed with a. pinion 33 secured upon a hollow shaft 34a mounted in a bearing formed in the bracket 12, the said hollow shaft 34a havingsecurcd thereon at the other side of the bracket a jaw-clutch member 33a (Fig. 6) formed with a brake surface 33b and adapted to mate with a clutch member 213 which is splined upon a shaft 34 journaled in the hollow shaft 34a and having driving connection, through a sprocket 35, sprocket chain 36 and reduction gear 37, with al motor` 38. I

For engaging a tire bead core 39 and drawing it into the winders the machine is provided at the inner side of each Winder with a hook, 41 or 42, formed upon the projecting end of a slide 43 or 44, (see the slide 43, Fig. 3), the slide being formed with guide-receiving slots or openings and mounted upon guide blocks such as the blocks 45, 47 mounted upon the

shafts

25 and 31. The hooks 41 and 42, as will be seen upon refer ence to the hook 41, Fig. 3, are adapted to receive the bead core 39 from below when the hooks are in projected positions outside of the peripheries of the respective winders, and upon retraction of the slides are adapted to draw the bead core to the axis of the winders, through the radial slots of the'l latter, as shown in Fig. 3, and to clamp the bead core against the end walls of the slots in the winders shafts `(see Fig. 5).

Acting at theouter side of each of the winders to assist in drawing the bead core into wrapping position andy to ejectl the core from the winders after it is wrapped, a slide 47 or 48 (see the slide 48, Fig. 2), generally similar to the slide 43 of Fig. 3, is mounted upon guide blocks, suchas the blocks 50, 52 in Fig. 2, which are mounted upon the

shafts

25 and 31 respectively. Each of these slides is formed near its forward end with a down-v wardly extendingprojection, 53 or 54,

adapted to eject the bead core 39 fromthe winders in the forward movement of the slide, and pivoted to-the forward yend of the slide as at 56 (see Fig.` 2) is a sector-shaped plate, 57' or 58, formed with a peripheral notch such as the notch 60 (Fig. 2), adapted to receive the bead core 39 from below when the plate. in its lowermost position, as

rocking frames

145, 147 are mounted. The said rollers7 frames areconncctcd by a pull spring such as the spring 159 to'hold the rollers against each other when they are retracted 'from the work and to permit them to spread apart upon the work as they are pressed thereagainst, to roll and press the tape against the bead core 39 in opposite directions from one corner thereof, as shown in Fig. 3. A stop 161 is provided upon the face of thewinder to limit the movement of the adjacent arm of the lever 153 toward the Winder' axis when the Winder is empty and stops 163, 165 are provided upon the said arm and adapted to engage rearward projections of the rocking frames 145, 147, beyond their pivots, to assure proper positioning of the

rollers

141, 143 when they are in a retracted position and also during their movement to- Ward the work. i

- For withdrawing the rollers, 141, 143, from the Work at the end of each wrapping operation and for holding them ,retracted while the Winder is stopped, the actuating arm of the lever 153 is provided with a cam roller 167 adapted to coact with a cam arm 169 when the latter is presented in the path of the roller. The cam arm 169 is slidably keyed upon the shaft 28, a generally similar cam arm 170, formed to clear the hub pinion 29 of the gear 27, being secured on the shaft 28 for actuation of the tape rolling devices of the other Winder, and the shaft 28 is provided with a rocker arm 171 (Figs. 1 and 3) having at its outer end a cam roller 172 running in a .cam groove 173 formed in a cam `-disk 174 secured upon the main drive shaft 31, the said cam disk being adapted to cause the earn

arms

169, 170 to he lifted into position to coact with the rollers, such as the roller 167, of the tape rolling` devices, at the 'end of each operation of the winders. to retract the rollers such as the

rollers

141, 143 from the work and hold them in retracted position until the tape ends have been fed into position to be stuckto the next bead core and .unt-il the bead core has arrived at the winding position.

For assuring the proper stopping and holding of the winders in work-receiving position, with their radial work-receiving slots in registry with the slots formed in their shafts, a ratchet disk 175 is rotatably mounted upon the shaft`28 and secured to the gear 27.

For severing appropriate lengths from the leading end portions of the tapes 95. 96 after the rollers such as the

rollers

141, 143 have attached the leading ends of the tapes to the bead core, and -for gripping the severed lengths of tape with sufcient force. to cause them to he drawn onto the core with suitable tension, each Winder is formed with a pair of guide ways, 183, 183 (Fig. 3) or 184,184 (Fig. 5), for a pair of slides, 185, 187 (Fig. 3) or 186, 188 (Fig. 5), which are connected on the outer side of the 'Winder by a pair of

toggle links

189, 191 or 190, 192, and by

Ia pull spring

193 or 194 adapted during rotation of the Winder to hold the slides together with their toggle in broken position.

f On the inner side of the Winder the slides ing position, to separate the slides and admit adapted to be occupied by the said stud when are provided on their upper faces With shear plates such as the plates 195, 197 (Figs. 3 and 4) adapted to sever the tape as the slides are brought together upon the latter, and the slides are provided With downwardly extending grippers such as the

grippers

199, 201 adapted to grip the severed length of the tape as shown in Fig. 3, under the force of the

spring

193 or 194, to cause the Winder to pull the tape onto the bead core Withappropriate tension, the tape gradually slipping from the said grippers as the Winder' rotates.

For straightening the toggle at the times when the Winders are stopped in Work-receivthe next'length of tape, and then to break the toggle and. permit the slides to be drawn together by the spring to sever and grip the tape, an arm, 203 or 204, is secured upon the shaft 91 and formed at its outer end with a laterally facing slot disposed tangentially of the Winder and adapted to receive a stud, 207 or 208, mounted upon the hinge pin by which the slide actuating toggle links are connected With each other, the slot vbeing the Winder' is stopped in Work-receiving position. v

For appropriately lowering and raising the

arms

203 and 204 the shaft 91 is provided with a rocker arm 210 having at its outer end a cam roller 211 (Fig5) running in a cani groove 212 formed in the rear face of the mutilated gear 30.

For cyclic operation of the machine in succesive wrapping operations the jaw-clutch member 213, splined on the shaft 34 and adapted to mate With the jaw-clutch member 33, is circumferentially groved and engaged by a shipper fork 214 (Fig. 6) formed on the upper arm of a three-armed lever 215 secured upon a shaft 216 which extends to the trout ofthe machine, the lowermost arm 217 ol the lever 215 being connected With a part ot' the machine frame by a pull spring 218 adapted to urge the clutch member 213 toward disengaged position.y

For latching the clutch member 213 in engagement with the clutch member 33a the lever 215 has a middle arm 219 adapted to be engaged by a shoulder formed upon a latching lever 220 tuleruuied on the 'frame of the machine at 221 (Figs. 2 and and urged toward latching position by a pull spring 222 (Fig. 2) connecting its lower arm with the machine frame, the construction `and arrangement being such that when the clutch member 213 is thrown into driving engagement it is so held by the lever 220 and the latching arm 219 until the said latching lever v push rod 223 (Fig. 2) is slidably mounted in themachine frame in position to be thrust against the lower arm 220 oi' the 'lever 220 and is provided at the front end of the ma` chine with a hand knobA 224 backed by a compression spring 225 seated against the machine frame to hold the push rod 223 normally out of contact` With the latching lever 220.

For turning the latching lever 220 to unlatching position to stop the machine automatically at the end of each operation of the Winders, the upper arm 220b of the said lever extends into the path of a dog or cam 226 mounted on the periphery of' the cam disk 174.

To 4prevent over-running of the machine upon the disengaging of the clutch, member 213 a brake arm 227 (Fig. 6) is secured upon the shaftV 216 and is adapted to coact With the braking surface 33h formed upon the clutch member 33 under the force of the spring 218 when the clutch is disengaged.

For throwing the clutch into engagement, the front end of the shaft 216 has secured thereon an arm 228 (Figs. 1, 2 and 7) Which has its lower end pivoted at 229, with substantial play, to a doWnwardly extending arm 230, operating past an over-center position (Fig. 1), o'f a bell crank lever 231 fulcrurned upon a stub shaft 232, the other arm 233 of the bell crank lever being connected by a link 234 with a foot lever 235 ulcrumed at 236 on a bracket rising from the base of the machine, an intermediate part of the link 234 being connected by a pull spring 237 with a higher part of the machine frame, so that the spring 237 acts With the spring 218 to urge the clutch member 213 toward declutched position. Ths the arrangement is such that depressing the foot lever 235 engages the clutch and the clutch thereupon is held engaged by the latching lever 220 and the latching arm 219 ot' the lever 215 (Fig.`

6) until the lever 220 is tripped, either by the operator pressing the hand knob 224 or by the cam or dog 226 striking the upper arm 220b ot the lever and forcing it to the position indicated in broken lines in Fig. 3.A

Secured to the machine frame in position vautomatically to receive upon it the successive bead cores ejected from the winders is a large hook 238 (Fig. 7).

The multiple-bearing bracket 11 preterably is mounted upon a slide l1 provided with a handwheel 11b Fig. 1) and `feed screw 11'" (Fig. and the rotating parts adjacent the bracket are swiveled thereto, and splined upon the transverse shafts of the machine as shown at 300, 300 and 301, 301 in Fig. 1, so that the left-hand winder 13 and its associated ineehanisnis eau he all adjusted together from and toward the otherwinder, as l' neerzet@ indicated by the dotted line position of the tape-drawing slide in Fig. 1, to adapt the machine for bead-cores having the ends of the winding overlapped a greater or less distance.

Operation In the operation of the machine, the motor and connected parts up to and including the clutch m mber 33a being continuously driven but with the clutch disengaged, the coredrawing slides 43, 44, 47 a, '48 being in their forward positions, the tape-drawing slides 97, 98 being in their upper positions and the

toggle actuating arms

203, 204 being in their upper positions with the

studs

207 and 208 stopped in their notches, the operator presents a bead core 89 to the core-drawing devices as shown in broken lines in Fig. 2 and passes the core into the notches of the pivoted plates, such as the "notch 60 there showmand further lifts the core, which tirns the plates upward to their work coniining positions, in which they are latched by coaction of the stud such as the stud 64 with the spring clip such as the spring clip 68.

rlhe operator then depressesthe foot lever 235, which throws in the clutch, the lever 220 automatically latching it in driving engagement.

ln the resulting operation of the machine, the descent of the toggle actuating levers 203, 204 spreads apart the tape-gripping and severing slides, such as the

slides

185, 187, to the positions shown in Fi 4, after which de-- scent of the tape-drawing slides 97, 98 carries the end portions of the tapes past the axis of the winders, as sl'iown in Fig. 4, in position to receive the bead core 39 upon the arrival of the latter, the

presser rollers

141, 143 being held in retracted position at this time by the cam arm 169.

The core manipulating slides are then drawn rearwardly, pulling the bead core through the radial slots of, the winders to the wrapping position at the axis of the winders, and upon the arrival of the bead core against or adjacent the tape ends, the arm 169 is lowered from the position of Fig. 4 to the position of Fig. 3, permitting the spring 157 to force the

rollers

141, 143 against the end portion of lthe tape and stick the latter to the bead core by vrolling in opposite directions thereon to the position shown in Fig. 3. Thetape-drawing slides then rise, sliding upward on the tapes, whose lower ends are now anchored to the bead core, and as soon as the tape-drawing slides have risen from between the gripper and cutter slides 185, 187 the latter are brought together upon the tape by a rising movement of the arm 203 to its original position, the shear-

blades

195, 197 severing a suitable length from the tape as the slides come together, and the

gripper members

199, 201 of the slides gripping the severed length of tape.

Immediately thereafter, the mutilated gear 30 comes into mesh with the pinion 29 (see- Fig. 5), the cam 181 lifts the pawl 177, and the winders are consequently rotated, through a sufficient number of revolutions Vto completely wind the severed lengths of tape upon the bead core, the winders then stopping when the mutilated gear 30 passes out .of 's mesh with the pinion 29 andthe pawl 177 drops into the notch 176 (see Fig. 5) of the ratchet disk 175, the winders stopping with their radial slots `in registry with the slots of their shafts.

Continued rotation of the main drive shaft then causes the core manipulating slides 43, 44, 47a, 48 to run forward until their Working engaging portions are beyond the peripheries of `the winders, to the positions Ishown in broken lines as to the slide 48 in Fig. 2, and as the pivoted core-retaining plates, such as the plate 58, pass the peripheries of the winders they are forced downward about their pivots by engagement with the` respective pawllike trippers such as the one shown at 70, releasing the wrapped bead core and permitting it to drop into a position in which it is pendently supported by the hook 238 (Fig. 7).

The dog 226 on the cam disk 174 then engages the upper arm 220b of the latching lever 220 and disengages it from the latching arm 219 of the lever 215l (see Fig. 6), which permits the springs 218 (Fig.6")and 237 (Fig.

brake 227 machine. The operation as described is then repeated (Fig. 6), and thereby stop the as to successive bead cores."
