MEANS FOR FORMING METAL RIBBONS.

Specification of Letters Patent.

Patented Sept. 2,1919.

Application filedJJeccmber 1, 1916. Serial No. 134,296.

To all whom it may concern:

Be it known that I, EDWARD JOHNSON, a citizen ofthe United States, residing at St. Paul. in the county of Ramsey and State of Minnesota, have invented certain new and useful Improvements in Meansfor Forming li'lctal Ribbons, of which the following is a specification. y

7 My invention relates to means for forming metal ribbons used in making Well screens and has for its object to provide mechansim for arranging a multiplicity of shaped elements which are wider at one portion than another, so that the narrowest portions will be turned in one direction and the elements held parallel and spaced a desired amount between their widest portions, together with mechanism for applying solder tosaid elements at intervals, whereby a continuous ribbon is formed which may be wound upon a perforated tube to construct a'well screen. The elements are preferably formed of wire which is triangular in cross section and which is wound with one apex of the wire at one outer limit of the resulting ribbonand a side of the wire in the other outer limit.

The total number of wires needed to form the ribbon are passedin parallel relation between a roller and a holding block whereby they are arranged and spaced. As so held, the ribbon'thus formed is passed over a drum where a flux is applied at intervals along the ribbon and upon anotherdrum a soldering head is successively clamped over ti o ribbon at the points where thefiuX was applied, and solder ejected aboutfand over the wires to secure them in their fixed relation. The ribbon thus formed is then scraped clean from excess of solder and wound upon ar el. Operations are automaticallv and continuously performed by my machine so that an attendant is only needed to supply the rawinaterial and re= move the product. p

The full objects and advantages ofmy inrcntion will appear in connection with the detailed description thereof and are particularly pointed out in the claims.

In the construction of my well-screen ribbon I prefer to use triangular wire which when arranged and constructed as shown in Fig. 22 comprises the finished ribbon. which may be wound upon aperforated pipe to form a. well screen capable of being driven.

The various steps followed in constructing this ribbon are most clearly shown in 1. Strands of the triangular wire 30 are fed into themachine between two

drums

31 and 32, of which drum 32 is the driver and druni 31 an idler. The drum 31 is provided with circumferential grooves 33, as best seen in Fig. 21, into which the strands are forced by a head 34 clamped tight upagainst the faces of the strands. As the wires 30 pass over drum 32 said wires have applied to them at certain regular intervals a soldering flux contained in a tray 35 by means of a toothed roller 36 which engages a conical roller 37 partly immersed in the flux. Roller 36 and drum 32 are geared to revolve in aratio such that a tooth 38 on roller 36 shall always come opposite to a groove 39 on the periphery of drum 32, permitting the flux applied to wires 30 to flow freely about the same and be properly applied thereto without daubing drum .32. In leaving drum 32 the wires pass over a second drum 40, which is provided with circumferential grooves 41 similar to grooves 33 in drum 31, and is also provided with transverse pockets 42. Drum is geared to rotate with drum 32 so that the spots on the wires which have been coated with flux always come opposite the pockets 42 in the drum 40. While the wires are passing about drum 40 a soldering head 43 communicating with a. solder pct 44 is successively brought up against the drum 40 and clamped thereto by a toggle clamp 45 and solder ejected from the pot 44 through head 43 about the wires'30 into the pockets 42 provided for that purpose by means of a pump 46 extended down into said solder pot. A perfect soldering action cannot be effected unless the metal to which the solder is to adhere is raised to the temperature of the solder. In my machine this is accomplished from the fact that solder not only is applied about the wires and in the pockets 42 by the pump 46, but an excess of this solder is passed over the wires discharging back into the solder pot, this flow of solder continuing for a time sufficient to raise the wires or strand to proper soldering temperature. Head 43 is adapted to travel with drum 40 for a short period of time while solder is being ejected about and over the joint and then is returned to its original position, be ing then ready to form the next joint. Be-

fore the ribbon leaves the drum 40 it is cleaned by being scraped with a knife 47. The ribbon finally passes over an idler 48 and is coiled upon a reel 49, from which it may be easily removed in coils.

The frame of my novel machine, as best shown in Fig. 2, consists of a box-like structure substantially open at the front and rear, comprising

side members

50 and 51 and top and

bottom members

52 and 53. This structure is supported upon pairs of

legs

54 and 55 attached to the frame member 36, which legs may be bolted to the floor.

The drivingmechanism for the machine is most clearly shown in Fig. 3. A motor 56 is bolted to a bracket 57 issuing from the

frame members

50 and 53. Bracket 57 is provided with an upright portion 58 to which is secured along bearing 59 supporting the motor shaft 60. The aperture 61 in portion 58 of bracket 57, through which bearing 59 extends, is of ample size so that the motor shaft and a worm gear 62 secured to the end thereof may be passed through said aperture. thus facilitating the assembling of the machine. Vorm gear 62 meshes with a worm wheel 63 loose on a shaft 64 journalcd at one endin a boss 65 integral with the frame menn ber 51 and at the other end in a boss 66 formed on a plate 67 bolted to the frame member 50. Plate 67 covers an aperture 68 in the frame member 50through which the shaft 64, with all its parts, may pass in assembling the machine. Worm wheel 63 is provided with a clutch member 69 engaging a corresponding clutch member 70 splined to shaft 64, which latter clutch member may be operated from the front of the machine by a lever 71 pivoted to an arm 72 issuing from frame member 50 and terminating in a forked portion 73 operating in a groove 74 in said clutch member. Shaft 64 may hence be considered as the drive shaft of the machine.

The method of attaching the drum 31 to the machine and details of the arranging head 34 will be found in Fig. 21. A studded screw having an enlarged central portion 7 is threaded at both ends 76 and 7 7 and is attached to the frame member 52 by the end 77 which is screwed therein. J ournaled upon the enlarged portion of this stud is the idler drum 32 which is retained thereon by a washer 79 and a nut 78 screwed on the end 76 of said stud. The head 34 of the arranging and spacing member is slidably mounted in a socketed casting 80 attached to the frame member 2 through a base plate 81. Head 34, as noted in Fig. 21, is, provided with a. stem portion 82 which slides in the socket 83in casting 80 and can be advanced up against strands 30 with any desired pressure by means of a screw 84 which is threaded into casting 80 and butts up against the end of stem 82.

The flux applying device is best shown in Figs. 1 and 4. Drum 32 is attached to a reduced portion 85 of a shaft 86 journaled in .

bosses

87 and 88 integral with

frame members

52 and 53 by a washer 90 and a nut 91. Roller 36 is similarly secured to the reduced end 89 of a shaft 92 journaled in

bosses

93 and 94 integral with the

frame members

52 and 53 by means of a similar washer 95 and nut 96.

Shafts

86 and 92 are geared together by

gears

96 and 97 fast thereon and are driven by a drive to be later explained. The teeth 38 on the roller 36, as best seen in Fig. 1, have inserted in them strips of felt or cotton 96 which run the length thereof and which receive flux from the cone roller 37 and apply it to the strands on the drum 31. The tray 35 extends under drum in Fig. 5.

igsre oea 31 so that all of the fiunwhich drops off from thestrands 30 returns to the tray. Tray 35 also extends outbeyond the rear of the frame member 52, where a corked draining spout 97 is provided. The cone roller 37 is preferably made of felt the more easily to retain and earrythe flux, and has a stem 93 attached to it whiclrrotates in a bearing 99 integral with a bracket 100 secured to the bottom of the tray35. The apex of cone roller 37is ninety degrees, so that the lower portion of the cone travels in the flux parallel to the, tray 35 and the forward portion of the same travels parallel to the flux applying roller36. Roller 36 fits tight enough up against roller 37 so that the latter is rotated a small amountevery time one of the teeth 38 engages it. Inthis manner the flux is brought up from the tray 35 to the spaced Wires 30. To prevent flux from entering the bearing 93 of shaft 92, a boss 115 integral with tray 35 is provided which surrounds a portion ofshaft 92and roller 36 and extends up even withthe top of said tray. 1

The soldering drum 10 and the drive for it, as well as the drive for the drum and roller 36, are shown in Figs. 3, 5 and 11. Referring to Fig. 11, drum 10 is bolted to an escapement wheel 101 which inturn. is secured by a key 102 to a hollow shaft 103 journaled in bosses 10% and 105 integral with the

frame members

52 and 53, as seen Shaft 103 has securedto it adjacent the hub 105 a spur gear 100 \Ylllill meshes with the gar 90 on shaft and a bevel gear 107 meshing with abevel pinion 108 below it, as seen in F 3, attached to a short shaft 109 journaled in a boss110 integral with the frame member 51. Shaft- 109 extends out beyond frame member 51 at 112, where it has attached to it a spur gear 111 meshing with a spur gear 113 secured to asimilar portion 111 of the drive shaft 62L. 'Gears90, 97, and 100 are so proportioned that as the same rotate the slots on the drum 32 and pockets in drum 40 always come opposite the placeson the wires 30 coated with flux by the roller 36. The ratio of gears between shaft 6% and shaft 103 is such that When shaft 103 has rotated through an angle equal to that between two of the pockets 42 on i drum 4-0 then shaft 64 shall have completed one revolution. All of the operations pertaining to each joint in the ribbon can hence bereferred to a single revolution of shz'tfts 6t, and will be so discussed.

In forming the soldered joints, as before stated the soldering head -13 is first clamped against, the drum 10, then follows it for a period of time while solder is being forced about and over the wires 30 at the joint, and is finally released and returned to its original position to engage the wires 30 at the new joint to be formed. The device for successively performing these functions is clearly shown in Figs. 1, 5, 11, 12 and 13. Rotatable on shaft 103 and shouldered against a portion 116 of disk 101, which protrudes throughthe drum 4:0, is a casting 117 supporting the soldering head 13. Casting 117 and disk 101 are secured from longitudinal motionon shaft 103 by a collar 118 integral with said shaft and resting upon the frame member 52' and by a nut 119 tapped to screw upon the end of said shaft against a shoulder 120. Casting 117 has radially-extending

portions

121 and 122 of which portion 121 supports a vertically swinging arm 123 pivoted thereto at 124-. The lower portion 1250f arm 123 has secured to itthe solderinghead 13,-which will later be explained in detail, and the upper portion 126 of said arm is forked and has PIVOtQCl to it at 127 a member 128 of a systemof toggle levers, the other member 129 of which is pivoted at 130 to a forked lug 131issuing from the radial portion 122' of casting 117. It will be noted that member 128 of the toggle levers is forked at 132, where it has pivoted to it at 133 the other member 129 of said toggle levers. The toggle is "operated by a forked head 131 through which the same pivot 133 extends, which head is securely attached to the end of a rod 135 freely positioned within the hollow shaft 103. The lower end of rod 135, as best seen in Fig. 5, is securely bolted to one member-136 of an end thrust ball bearing, the other member 137 of which is clamped to a sleeve 138 surrounding the rod 135. threaded to lar 139 which can be vertically adjusted Sleeve 138 is receive a channeled col- 14A and L15, respectively, engaging cams- 146 and 14-7 attached to shaft 64. Cam 14.6,

as clearly shown in Fig. 5, is lowest at 148,

rises gradually at 1 19,is uniformlyhighest at 150 for the greater part ofthecircuniference of the same, and drops quickly at 151 to the elevation at 148. Cam 1417, which is simply a follower and is complemental to cam 1 16, serves to pos1t1vely actuatelever arm 1 10. As shaft 64 rotates in the direction shown by the arrow, the portion 149 of cam 146 engages roller 144:, causes lever 1410 to be oscillated downward and clampsthe head 4.3 against drum 40. The

head 43 remains clamped for the greater part of the revolution ofshaft 64:, while the roller 144: rides upon the cam surface 150 and quickly disengages when said roller path of the oncoming tooth 168.

engages surface 151, remaining released a short time whlle at 148. This efiectually clamps head 43 agalnst drum 40 and permits it to remain in contact while solder is flowing for the greater part of the revolution of shaft 64 and quickly releases the same at the proper time.

The mechanism for oscillating and accurately timing the clamping head and toggle arrangement is shown in Figs. 1, 3, 5, 6, 7, 11,12 and 13. As best shown in Figs. 1 and 5, the radial portion 122 of casting 117 extends downward at 151, where it is grooved at 152 to receive a verticallypositioned pin 153 having a tongued head 154 adjustably held in said groove by a bolt 155. Pin 153 is engaged by a slotted arm 156 keyed to a vertically-positioned. shaft 157 and-is adapted to operate in a slot 158 in said arm. Shaft 157 is journaled in

bearings

159 and 160 east with the

frame members

52 and 58 and is adapted to oscillate to move the toggle head back from one joint to the next. Attached to shaft 157, as seen in Figs. 6 and 7, is a casting 161 to which is secured a diagonally-positioned flat spring 162. Spring 162 carries at its extreme end a forked bearing 163 in which is pivoted a spherical-surfaced cam roller 164 engaging a cam 165 fast upon the drive shaft 64. As best seen in Figs. 12 and 13, arm 156 is provided with a detent 166 which is adapted to engage, as hereinafter described, a number of

teeth

167, 168, etc., on the disk 101 which equal in number and rotate in fixed relation to the die pockets 42 of drum 40. When the cam 165 is positioned as shown in Fig. 6, arm 156 and the toggle head are positioned as shown in Fig. 13, with detent 166 free from and out of the path of the

teeth

167, 168, etc. As shaft 64 rotates, roller 164 engages the cam surface 169, and arm 156 and the toggle head are shifted approximately to the positions shown in Fig. 12 through the medium of pin 153 and slotted arm 156, with the detent 166 in the At this instant roller 164 should be at the highest point 17 0of cam 165. After the arm 156 arrives at the position shown in Fig. 12 the detent 166 is picked up by the advancing tooth168, reversing the motion of lever 1.56, and through pin 153, the motion of head 1 17, which is still free to rotate independ' ently of drum 40, as the toggle is open. The casting 117 carrying soldering head 43, is therefore timed accurately and caused to move forward with drum 40 through engagement of detent 166 and tooth 168,

lever 156 having ceased to receive motion from cam 165-and the toggle still being open. The soldering head 43 is now clamped to the drum 40 by the toggle device previously described. The casting .117 now rotates with drum 40, driving lever 156 in its backward stroke through the means of pin 153 and slotted arm 156, the relation of the parts being such that the detent 166 ceases to contact with tooth 168 and moves rap-idly out of its path, where it remains until the revolution of shaft 64 again brings cam surface 169 into play. The cam surface 171 of cam 165 is negative only and might be left out as the retraction of lever 156, and through it lever 162, is secured from the toggle-head as described.

The adjustment afforded by groove 152 in head 117 and tongued head 154 of pin 153 serves to secure the accurate alinement of solder head 43 and die pockets 42 acting through detent 166 and

tooth

167 and 168 as described. The casting 117 and solder head 43 continue to rotate with drum 40 until the operation of making a solder joint has been completed, when the toggle is ,opened by cam surface 149 and lever 140 and they are free to be returned to the position of Fig. 12, as described.

During the period of time when head 43 is clamped against drum 40 solder is being discharged through said head by a device shown in Figs. 8, 9 and 10. A tube 172 is supported in a socketed bracket 173 attached to a portion 174 of the frame issuing from the

frame members

50 and 53 and. by a casting 175 attached to a portion 176 issuing from the

frame members

50 and 52, said casting having a. fluted head 177 extending down into said tube. About the upper portion of tube 172 and spaced therefrom is a casting 178 secured to said tube by set-screws 179 and having cast therewith a circular frame portion 180 supporting the melting pct 41. Frame portion 180 has secured to it a jacket 182 having a vent pipe 183 leading from it to the rear of the machine, as shown in Fig. 5. Pot 44 is heated by means of a Bunsen gas burner 184 of usual construction supported from a bracket 185 attached to tube 172. The function of the tube 172 and the fluted connection 177 is to serve as an insulator to prevent heat from traveling to the major portion of the machine and greatly raise the temperature of the same. Attached to casting 178 and frame 180 by means of a bracket 186 is a pump 46 having a cylinder 187, shown in detail in Figs. 9 and 10. The cylinder chamber 188 comnmnicates through

ports

189 and 190 with a pair of

valve chambers

191 and 192 provided in a casing 193 issuing from the bottom of the cylinder 187.

Chambers

191 and 192 are closed at the tops by

caps

194 and 195 having

valve seats

196 and 197 therein engaged by

balls

198 and 199, which balls are limited in motion by

pins

200 and 201 passing diametrically through the

chambers

191 and 192. (lasing 193 forms a third chamber 202 which is socketed to receive the spherical end 204 of a tube 203, which end is held in place for uni versal movement relative to said casing by means of a socketed plate 205 screwed thereon. A leakage port 206 is provided whichleads to chamber 188 and whiclrn iay be partially or completely closed by a screw 207" extending up above themelting pot 4:4. Cylinder 187 is provided witha piston 208 which is operated by means to be presently described. lVhen thepot 441 is filled with solder the

balls

198 and 199 floatand are normally seated against; the

seats

196 and 197.. As the piston 208 raised, solder is drawn through valves 195 and 194: and also back through the tube 203 to fill the cylinder chamber 188. Upon the reversal of the movement of piston 208 the balls .198 and 199 again seat themselves and solder is forced up through the tube 203 and into the soldering head 43 with which said tube com municates. The quantity i of solder discharged through head 43 is regulated by the leakage port 206 and valve 2.07,so that the excess amount is discharged out of cylinder chamber 188 through said port. i a The means for operating the a charge pump 44: shown in Figs t and 8. Piston 208 is connected to a piston rod 209 by a ball-and-sooket oint 210. bridge 211 connects piston rod 209 with a rod 212 parallel thereto and slidably mounted in thehead 17 7 and the bracket 3. Rod 212 issecurely fastened in bridge 211, but rod 209 is secured therein for both longitudinalyand lateral adjustment by means of a pair of

nuts

213 and 214 advanceable upon the end 216 of rod 209 and passing through a slot 215 insaid bridge. As seen in Fig. 1,. rod 212 passes through bracket 17 3 and is p ovided at its lower end with a forked head 217 to which it is loosely pivoted at 218 one arm 219 of a bell-crank 220. Bell-crank 220 is pivoted in a casting 221 bolted to the underside of the frame member 53, and the other arm 222 of said bell-crank extends up through an aperture 223 in said frame member and carries a cam roller 22% which engages a cam 225 fast on shaft 61. Cam 2251s made with a graduallysloping surface 226 which operates the pump uniformly to cause the sameto deliver solder into the soldering head 43 while thelatter is clamped to the drum 40. Cam roller221is kept in engagement with cam 225 by means of a tension coil spring 229secured to arm 222 and to the bracket 57 of the frame proper. As the roller224c is caused to follow surface 228 of cam 225 by means of spring 229 to pass from the position shown in dotted lines in Fig. 4, to thefullline position, solder is drawn into the pump ready for another discharge. This latter action durates while the head 43 is being unlocked, returned and locked relatively to drum 4:0.

The soldering head and the connections between the same and the pump are shown solder disin detail in Figs. 11 and 23. Head 43 is made of a cylindrical bar and has a longitudinalghole 230 partly throughit which is ,eocentr cally displaced relative to the axis of the bar. Hole 230 is plugged at the top at-231 and turns at232 to leave the bottom of the head 4'3 atthe center of the head. The lower portion 233 of head 43 is threaded and socketed and receives a cap 234c which is also socketed, said sockets serving to hold a the cylindrical head 235 of a tube 236 for unlversal movement relative to said head.

Tube 203, leading from the pump 44:, is arranged to telescope into tube 236, as shown in Fig. 8,so thatthe head 4-3 may have a freedom to move with the drum 40 as previously prescribed and still communicate with said pump. Head 13 is slotted at 237 to form a longitudinal passageway from hole 230 to the exterior ofthe head. The

head is set in a socket 238 formed in the arm 123 and issecurely clamped inplace by a bar 239 inserted in a recess 24:0 in said head and secured to the arm 123 by bolts 24H. The passageway237 in head 13 COlIlr. municates through another passageway 242 in arm 123 with'a chamber 242, and said chamber terminates in a narrow nozzle formed by two blocks 24A: and 245 of stellite or other substance to which melted solder does not adhere, and through which the fluid metal is squirted againstt-he wires 30. These blocks are clamped in place upon the arm 123 by plates 24:6 and 247 screwed thereto and arefurnished with sharp-edged lips a in the dru1n4c0 and opposite a die pocket 42, thefiux also covering the wires 30 at that point, the molten solder is forced through slot 237 in a jet against and between the wires, raising them quickly to soldering temperature, the stream of slightly-cooled solder falling into the solder pot. This action is continued for a definitely-timed period duringwhichthe stream of molten solder is flowing over the wires and discharging. into the solder pot, so that the wires are certainly raised to the necessary temperature to effect aperfect soldering action.

The grooves 41 in drum 40 are cleaned from solder which may stick in them by a scraper 320 adjustably positioned in an upright 321 attached to the frame member 52.

Knife 47, which cleans the ribbon, is mounted on a bracket 322, which may also be adjusted a small amount.

The winding reel is best shown in Figs.

and b which come in direct contact with the

I

1, 2, 15, 16 and 17. A large wheel 248 on .Which the ribbon is wound, having the upper surfaces of the spokes 249 level with the top of the rim 250 and level with the bottom of the finished ribbon as it leaves the 'drum40, is pinned to a shaft 251 journaled in along tubular bearing 252 east integral with a bracket 253 bolted to the frame member 50. As best seen 'in Figs. 1 and '17, the upper portion 254 of shaft 251 is reduced in diameter and is threaded to receive and retain upon wheel248 a collapsible winding core. This core comprises four

segments

255, 256, 257 and 258, which when arranged together and properly spaced, as shown in Fig. 1, present a sectional disk having an annular groove 259 and a conical bore 260. Groove 259 is adapted to receive a flanged" annular ring 261, and the bore 260 is arranged to receive a truncated conical plug 262 provided with keys 263 engaging corresponding keyways 264 in the

variousse'gments

255, 256, 257 and 258. Plug 262 is bored to receive the end 254' of shaft 251 and serves towedge the said segments against ring 261 when a nut 265 on shaft end 254 is screwed down upon it. By this means the core formed is rigidly held togetherupon the center of wheels 248. In attaching the ribbon to the core the ribbon is bent and the bend inserted in one of the spaces between the segments. In removing the core, nut 265 is unscrewed and the whole coil and core lifted up from the wheel 248. When the coil has been properly bound to gether the'cone 262 is knocked out from the back, loosening the core membersand permitting removal of the same.

Shaft 251 is driven as shown in Figs. 2, 15 and 16. The lower end 266 of shaft 251 is reduced to form a shoulder 267 against w which is seated a flanged casting 268 held in. position by a nut 269 screwed on the end thereof. The flange 270 of casting 268 is recess e'd at 271 to receive a fiberwasher 272.

F Upon casting 268 is rotatably mounted a sleeve 273 which rests upon washer 272 and which is itself recessed at 274 to receive a similar fiber'washer 275. The sleeve 273 (is held'in place upon casting 268 by a washer 276 and a nut 277 screw-able upon the upper portion of'casting 268. i A friction drive is "hence .securable through the

fiber washers

275 and 272 between sleeve 273 and the casting 268. Sleeve 273 serves as one member of a plurality of overrunning clutches of which a plurality of

annular rings

278, 279 and 280 form the other vmen'ibers. These members are rotatably mounted upon the sleeve 273 and are held in position upon this sleeve by means of the flange 270 and a flange 281 integral with said sleeve. Each of

members

278, 279 and 280 is provided with drilled channels 282 which run into the bore of said members and each channel is provided with a ball 283 held by a compression spring 284 seated against a pin 285 in contact with the periphery of the sleeve 273. Said clutch members are further provided with radially-extending

arms

286, 287 and 2.88, which are screwed thereto as shown in Fig. 16. When these arms are successively oscillated wheel 248 is given a substantially uniform rotation.

Arms

286, 287 and 288 are indirectly operated from shaft 64. As shown in Fig. 2 a

miter gear 289 is attached to the end of shaft 64 protruding beyond bearing plate 67, which gear meshes with a miter gear 290 attached to a shaft 291 journaled in a boaring 292 rigidly secured to said plate 67. The lower portion of shaft 291 has attached to it three

eccentrics

293, 294 and 295, whose

eccentric rods

181, 296 and 297 are provided with pairs of

pins

298 and 299 which engage the

arms

286, 287 and 288, respectively, and cause the wheel 248 to be rotated.

It will be comprehended that as the coil of ribbon 300 upon the wheel 248 increases in diameter, the wheel 248 will have to be proportionately rotated at a slower rate. To effect this I shift the position of the point of engagement of the eccentric rods with the

arms

286, 287 and 288 in proportion to the diameter of the coil 300 as follows. Journaled in a bearing 301 integral with the bracket 253 is a shaft 302 to the upper end of which is attached an arched arm 303 having a roller 304 mounted at the end thereof and engaging the periphery of the coil of ribbon 300. The lower end of shaft 302 has attached to it a downwardly-slopi11g arm 305 which terminates in a fork 306 embracing all of the eccentric rods. Fork 306 is practically under roller 304, and shaft 302 is substantially in alinement with shaft 291. Roller 304 is kept in engagement with coil 300 by a spring 325 secured to arm 305 and the frame proper. As the coil 300 increases in diameter arm 303 is swung outward and the arm 305 is correspondingly caused to shift the eccentric rods and increase the length of the

lever arms

286, 287, and 288 to cause wheel 248 to rotate at the proper speed to wind the ribbon. The friction drive between the clutch member 273 and the shaft 251 provides for any irregularities in the action of the winding device should the same cause the wheel to rotate too great an amount.

In Fig. 14 is shown a counting device by which the length of the ribbon in coil 300 may be determined. A counter 307 of ordinary construction, having actuating arms 308 and 309, is connected by means of these arms to a connecting link 310 eccentrically pivoted to a gear 311. Gear 311 is the last of a train of reducing gears 312 driven from the pinion 113, and the train is so proportioned that the counter 307 records in feet.

In constructing ribbon of different sizes or shapes of Wire, or having different spaces between the Wires, the

drums

31, 32, 36 and 40 have to be removed and new ones replaced the slots thereon to take the correct positions relatively tothose on the drum 10; It will be noted in Fig. 11 that the Whole toggle head may be lifted off: fromthe machineby removing pin 133 and unscrewing nut 119. Drum 40 can then be removed and another placed upon the disk 101.1 Drum 4l0 can only be placed upon disk 101 innone position, Which is determined bythclrelations of the soldering head and the device for causing the sameto stop at the correct position for each oscillation of said head The adjustment for positioning, of slots andtheifluxapplying device is hence procured by adjnsting the other drums.
