A Worm ear 144 is supported on the shaft 141 and the hub 145 of the worm gear 144 is provided with a transverse slot 146 which receives a pin 147 secured'to the shaft 141. The end 148 of the shaft 141 rests in a suitable orifice 149 in the covercap 132 which rests in a circular opening 150 in the housmg extension 131 and forms a, bearing for this end of the v shaft 141. The other end 151 of the shaft 141 extends through the hub 135 of the gear wheel 134,'and this hub 135 serves as the other bearing for the shaft 141. The worm gear 144 meshes with the Worm Y the spindle shaft 3 causes rotation of the 'to' in turn transmits rotation to the vworm gear 144. Rotation of the worm gear 144 is also transmitted to the shaft 141 upon which the Worm gear is supported, dueto theslot- 146 and pin 147 connection between the worm gear 144 and the shaft 141, as already described.- The pinion 143 on the shaft 141 transmits rotation to the gear wheel 137 and the pinion 138 secured theregear wheel 134 rotatably supported in the orifice 136 in the housing extension131. The rotai5 152 and 153, respectively, secured thereto for tion of the shaft 141 and hub 135 on the gear wheel 134 will rotate the indicator arms purposes as will presently be described.

I The hub 135 secured to the gear wheel 134 protrudes through the central orifice 136 in the housing extension 131, and its reduced end portion 154 is threaded; The indicator 153 is supported on thereduced portion 154 of the hub 135 between-a washer 155 and a sprinr Washer-156. A washer 157' is now placed upon the reduced end 1540f the hub 135, and a nut 158 having screw-threaded engagement with the threaded end of the hub 135 forces the Washer-158 against the spring washer 156, causing it to grip the in dicator 153 and frictionally hold it in position on the hub 135 between the washers 155 and 156 so that as the hub 135 rotates the in- I dicator 153 will also move with it, and in addition, theindicator 153 can be moved A 'gagement with the threaded end of the shaft 141 forces the washer 159 against the spring washer 160, springing the same and causing it to grip the indicator 152 and frictionally hold it in position on the shaft 141 between,

the washers 159 and 160 so that as the shaft 141 rotates the indicator 152 ,will also move with it, and in'addition, the indicator 152 may be moved about its shaft support-141 to set the same at its zero position v The housing extension 131 is provided with a circular ridge 163 forming a dished circular portion in which I place a dial 164, suitably calibrated, the outer scale reading from 1000 to 10000, and the inner scale reading from 1 to 100, and to associate the indicator arm 153 secured on the hub 135with the 1000 to 10000 scale and the indicator arm the pinion143 on the shaft 141 will rotate of the scale;

this gear wheel134 inturn makespge onehundredth of a revolution.

- From this description it is'readily appa entthat for each revolution of theshaft i 141, the indicator arm 152 thereon will have traveled one revolution, indicating that one hundred convolutions of wire have been placed onthe spool associated with the windingspindle 3, and the indicator arm 153 of the hub 135 will point to the first graduation For each ten revolutions of the shaft-141, the indicator 152 will also have made ten revolutions,-and the-hub 135, due to the gearing ratio, will. have made onetenth of a revolution and will point to one thousand on the scale.

The rocker arm R which is pivo'tally supported upon the sliding member 79 is associated with adjustable means which controls the length of the stroke of the reciprocating is secured to the rocker arm R through the medium of this adjustable'means various lengths of coils may be wound, as will now be described. The rectangular plates 70 and 71 which form. the rocker arm R are vided with depending members 166 and 167 which, Whenthe plates 70 and 71 are secured together, form a depending leg 168, which is provided with a slot 169.

A rack 170 which rests in a suitable channel 171 in the housing C is provided with teeth 172 out in its side face 173 and is secured to a stud 174 intermediate of its ends by means of a riveting operation or any other suitable means. The forward end 175 of the stud 174 is 4 threaded and protrudes I through a slot 176 in the housing 0 and is adapted to receive a knob 177 and a collar 178 provided with a central orifice is adapted to be slipped over this protruding end 175 of the stud 174 and rests between the knob 17 7 and the housing C. The housing C is provided with a channel 179 which is adapted to receive the rectangular shaped portion 180 of the collar 17 8 to permit the collar 178 to slide up and down inlthe channel 179. The knob 177 and collar 178 are used for clamping purposes. A bushing 181 provided with fiat faces 182 rests in the slot 169 in the depending leg 168 of the rocker arm R and is adapted to slide in the said slot 169. The portion 1830f the stud 174. extends through a central orifice 185 in the bushing 181 and the reduced end 186 of the stud 174 Which protrudes, is threaded to receive a nut 187, a suitable washer 188 being placed between the nut 187 and the face of the depending leg 168 of the rocker arm R. The

throu hthe-bushing 181 is slightlylonger than t e bushing 181, so that when the nut 187 is turned down, the washer 188 will be; locked but at the same time allow the bushing 181to rock on' the stud 174 and permit the bushing 181 to slide in the slot 169. The knob 177 which is threaded upon the forwardend 175 of the stud 174 which protrudes throu h the slot 176 in the housing 0 is provided with a handle 189 which facilitates turning of the knob 177. I The toothed rack 170 meshes with a pinion 190integrally formed with a rod 191 which extends through an 'orifice 192 in a boss 193 formed integrally with the housing 0 and its protruding end has pinned to it a knob 194 which may be'turned to rotate the pinion 190 which is in mesh with the toothed rack 170. To adjust the stud 174 in the slot 169in the depending leg 168 of the rocker arm R the knob 194 on the rod 17 0 the toothed rack 17 0 is raised or lowered in the channel 179 as the case may be.

- I As before described-the stud 174 is secured to'the toothed rack 17 0 and as the rack is moved up or down the stud 174 is also raised or lowered in the slot 169 in the depending leg 168 of the rocker arm R and when the proper adjustment is obtained the knob 177 is turned down by means of the handle 189 tolock the stud 174 in its adjusted position. The knob 177 is provided with an indicator arm 195 suitably secured theretowhich cooperates with a scale 196 secured to the housing C which give the operator anindication of the distance that the stud 174 is to be raised or lowered to change the throw of the rocker arm R for the various lengths of coils to be wound.

A square block 200 (Fig. 6) provided with integrally formed studs 201 and 202 are adapted to receive bushings 204 and 205 202 which protrudes through the bushing 205 has secured thereto, by means of a set screw 210 a shoe 211 which rests in a slot or channel 212 out in the. inner face of the cover cap 105, when the same is in position, and secured to the housing C. The block 200 is provided with a central orifice 213, which is adapted to receive a guide rod 214 which is adapted to be secured therein by means of a drive fit.

This guide rod .214 extendsthrough a guide' bearing 215, and serves as a guiding means for the rocker arm R in its to and fro travel. The shoe 211 secured tothe'stud 202 is provided with an orifice 216 which is adapted to receive the end of the dis tributing bar or reciprocating shaft 165, and secured therein by means of a drive fit. This distributing bar-165 extends through an-aligned orifice 317 in the side 5 of the housing 2 to which the distributing arm D is secured.

The cam members 60 and 61 as before described are secured respectively to the shaft- 64 and the sliding sleeve member 79 and as the profile or lead of the cam faces 217 and 218 of the cams 60 and 61 are the same they mesh or match when the distributing .bar orreciprocating shaft 165 is in its extreme left position as illustrated in Figs. 1 and 3. The cam 61 secured to the sliding sleeve member 79 is heldin engagement with cam 60 by means of a helical spring 219 around the shaft 64, one end of which rests against a plate 220 resting in the bore of the bearing 66 and its other end rests against the sliding member 79 on the shaft 64. The shaft 64 when rotating causes the cam 60 to rotate and the lead angle of this rotating cam 60 engages the lead angle of the cam 61 supported on the sliding sleeve 79 and forces the sleeve 7 9, its supported cam 61 and rocker arm R to the left with reference to Fig. 4, against the normal compression of spring 219 and when the sleeve 7 9 and its supported parts have reached theirlimit of travel in that direction and starts their travel in the opposite direction, the sleeve 79, and its supported parts are moved in the opposite direction under the influence of the compressed spring 219 with the lead angle of the cam 61 following the lead angle of the rotating cam 60 on the shaft 64 which will be more fully hereinafter described.

Referring to Figs. 1 and 10 I show. a distributor arm I) secured to the reciprocating shaft 165. The distributor arm D comprises a split member 221 secured to the reciprocating shaft-165 by means of a screw 222 which passes through a suitable orifice in the upper split portion of the. member 221 and has screw threaded engagement with a tapped orifice in the lower split portion of the memher 221 to clamp the member'to the reciprocating shaft 165. The member 221 is provided with apair of upwardly extending arms 223 and 224 which are provided with aligned orifices 225 for receiving a shaft 226 upon which an arm 221 15 secured, the said shaft 226 and its supported arm 227 being pivotally supported in the aligned orifices .225. A block 228 resting between the arms 228 is positioned between the arms 223 and 224 of the member 221 with the shaft 226 which supports the arm 227 resting in the slots 231 of the legs 230, and the arm 227 supported on the shaft 226-in turn-resting in the bifurcated portions 229 of the block 228. A threaded stud 232 which is threaded through a tapped orifice 233 in the block 228 is rotatably supported in a pair of aligned onfices 234 in the ear extensions 235 of the arms 223 and 224,- its one end being provid ed with a head 236 and its other end 237 being reduced to receive a knob 23.8 which is suitably pinned thereto.

- From the'above description it will beseen that the shaft 226 and its supported arm 227 are pivotally supported by the arms223'and f 224 of the member 221 and the block-228 provided with the slots 231 in which the shaft 226 rests and the bifurcated portion 229 in which the arm-227 rests in combination with the threaded stud 232 which is in a threaded engagement with the .block 228 forms adjustable means for moving the arm 227 to the right or left.- lVith the parts linked together as just described it is readily apparent that when the knob 238 is turned to the right with reference to Fig. 10-the the block 228 is moved .to the right with reference to Fig. 11. This movement of the stud 232 is also rotated and due to thescrew connection between the threaded stud 232 and the tapped orifice 233 in the block 228 block 228 to the right caused'the shaft 226 and its supported arm 227 to also move to v the right for the reason that the arm 227 rests in the bifurcated portion 229 of the block 228 and as the shaft 226 is'pivotally supported in the orifices 225 in the arms 223 and 224 of the member 221. These orifices.

225 form bearings for the sliding shaft 226 in its limited travel to the right or left. The shaft 226 which rests in the slots 231 of the block 228 forms a bearing upon which the block 228 slides and also prevents tilting of the" block 228 when the stud 232 is turned to move the block 228. When the knob 238 is turned to the left the block 228 is also moved to 'the left with reference to Fig. 11 andwauses the shaft 226 and its supported arm 227 to also move to the left for reasons already described. The movement of the block 228 ,to the right or left is limited for when it is moved to its extreme rightor left position the faces 240 and 241 of the block 228 will engage the respective inner faces 242 and 243 of the arms 223 and 224 of the member 221. The arm 227 extends forward toward the winding spindle 3 and sup ports a pair of ball bearing guide wheels 245 and'246 for theusual purpose of guiding the wire from the source of supply to the electromagnet spool upon which the wire is being wound. The arm 227 is adapted to be raised or lowered with reference to Fig. 10,

by reason ofits being pivot-ally supported by the shaft 226 and to maintain it in any of its adjusted up or down positions, I provide a leaf spring 247 Whichis secured to the member 221 by means of a screw 248. The

free end-249. of the angular portion of" the spring 247 engages a portion of the arm 227 and the tension ofthe spring 247 is such as to frictionally hold the arm 227 'in any of its positions. A stop 250 secure'd to the member 221 limits the movement of the arm 227 in its downward movement.

The removable cover capv 105 is secured to the housing G by suitable screws which Y i controlling the length of stroke of'the' reoiprocating shaft 165, I vwill now describe the operation of the winding'machineand the adjusting means for adjusting the length of stroke of the reciprocating shaft 165 from 1 left to right. Now when the clutch pedal of the power drive (not shown) is actuated the belt connection between the source of power and the pulley 4 on the spindle shaft 3 will rotate the spindle shaft 3; The worm 130 and the apparatus associated therewith for on the shaft 3 meshes with the worm gear 109, causing rotation of the worm gear 109,

and through the agency of the] pinion" 108 on the transverse shaft 107 upon which the worm gear 109 is secured. and the gear wheel 111, pinion 110 supported'by' the arm 112 and the gear wheel 106 and bevel pinion 101 ,on the transverse shaft 103, and the bevel gear on the shaft 64 rotary motion the cam 60.- to cause rotation of the same.

extreme right position with reference to Fig. 4 and the arrow indicated on the'cam 60 indicates the direzition of travel of-the cam 60 which "will move the reciprocating shaft 165 to the left.

As'the cam 60 rotates, the lead angle of the rotating cam 60 engages the lead angle of the cam 61 supported on the sliding sleeve member 79 and forces the sleeve 79 and its supported cam 61 androcker arm R to the left with reference to Fig. 4, against the normal compression of the spring 219. The stud 174 WlllCll is used for adjusting. the length of stroke of the reciprocating shaft 165 passes through the slot 'l69 in the depending arm 168 of the rocker arm R, and is locked in its adjusted position in the slot I show the"rcciprocating shaft 165 in its 1 10 is'transmitted to the shaft 64, which carries R rocks about theistud 174 and 176,in the housing C means of the locklug-knob 177 and therefore the-rocker, arm ivots about its pivot pins 90 and 91 on the s iding mem- .ber 71 and causes the upper end of the rocker arm Rto tilt to the left. The shoes 208 and T211 supported on the block 200- resting in the upper end of the rocker arm R now slide to theleft in their respective channels 209 and 212. The tiltingj of the upper end of the rocker arm to the left'is permitted, due to the fact that the studs 201 and 202 I 'of the block 200 which supportthe same in the. rocker arm R rest in the bifurcated ends of the rocker arm. R and permit the shoes 208 and 211 supported by the block 200 to move in a horizontal plane to the left in their respective channels 209 and 212. The bushing-181 in the slot 169 in the leg 1680f the rocker arm R is slidably secured therein as before described, and as the'lower endof the leg 168 of the rocker arm R moves to the right, the bushing 181- around the locked stud 174 rotates thereon" to permit =this movement, tothe right of the leg 163 I of the 'rocker arm R. The guide rod 214 secured to the shoe 211 slides through the guide bearing 215 and the combination of the guide rod 214 and the block 200 permits the free movement of the shoes 208 and 211 in the respective channels 209 and 212, and as the reciprocating shaft 165 is secured to the shoe 211 it also moves to the left. The

- movement to the left of the reciprocating of the lead -angle of .the cam 61 which is shaft continues until the-'apex'of the lead angle of the rotating cam passes the apex supported on the sliding'sleeve79 on the shaft 64 and when in this position] the reciprocating shaft 165 is in its. extreme left position with reference to Fig. 4. As the shaft 64 continues to rotate the lead angle of the rotating cam 60 being in engagement with the lead angle ofthe cam 61 on the sleeve 79, the sleeve-79 and its supported parts are moved in. the opposite direction under the influence of the compressed spring 2.19 which permits the lead angle of the cam 61 to follow the lead angle of the rotating cam 60 to permit the reciprocating shaft 165 j to move to the right.

When the lead angle of the cam 60 again matches or meshes with the lead angle of the cam 61 in which positionthe apexes of the respective lead angle of the cams 60 and 61 rest in thebascs of the respective lead angles of the cams GO and 61 the reciprocating shaft 165 is in its reciprocating shaft 165 also receives this to R, and shoes- 208 and 211 movement from left to right and vice verse is transmitted to the reciprocating shaft 165, and for one hand fro movement. Through the a ency of the cam 61, sliding member 79, roc er arm complete revolution of the cam 60, the reciprocating shaft 165 will have traveled from left to right and right to left to place two' layers of convolutions of wire on the spool supported between thehead on'the.

spindle 3 and the tail stock T,

The length ofstroke of the reciprocating shaft 165 is adjustabl'e, and to-this end 1 provide the sliding toothed rack 170 which is in mesh with the pinion 190.

To adjust the stroke of the reciprocating s 1 5 he locking knob 177 which is in threaded engagement with the threaded end of the stud 174 is loosened to permitthe stud 174 to be moved in the slot 176 in the housing C and the slot 169 in the leg 168 I of the rocker arm R. With the locking."

knob 177 loosened, the adjusting knob 194 secured to the rod 191 integrally formed withthe pinion 190 in mesh with the toothed rack 170 may be turned. Now to decrease the throw of the rocker arm R the knob 194 turned in the direction of the arrow indicated in 'Fig. 4 and causes the pinion 190 associated with the knob 194 and-which is in mesh with the toothed rack 170 to move the rack 170 down.- The stud 174 is secured to the rack 170 and is therefore also'meved down and as the'bushing 181 .issupported on the stud 174 it moves down in the slot 169 in the leg 168 of the rocker arm R. This movement 'of the stud 174 and its supporting bushing 181 in the slot 169 increases the distance between the horizontalsiidable pivoted center of the rocker arm R and-the fixed locking center, which in this case is the stud 174. This increase of 1 distance between the pivoted centers 90 and 91 of the rocker arm R intermediate of its ends, and the .fixed locking center or stud 174about which the bushing 181 supported thereon rocks, decreases the distance that the upper end. of the rocker arm R tilts from left to right and vice versa and as the reciprocating shaft is secured to the shoe 211, which is associated with the tilting end I of the rocker arm, the distances that the reciprocating shaft 165 travels from left to right and vice versa is decreased.

From the description, it is readily apparent that the reciprocating shaft 165 is providedwvith adjusting means for. accurately adjusting the length of its stroke, and it is also apparent from the description that the axjljusting means is inicrometric in that it provides an infinite number of adjustable positions for the fixed locking center or stud 174 to provide an infinite number of lengths of travel of the reciprocating shaft 165.

' of coil to be wound, the locking knob .177 7 When an adjustment of the reciprocating shaft 165 is obtained for a certain length w is again tightened to clamp the studl74 in its adjusted position in the slot 176 in the housing C, to maintain the adjustment.

From this it is apparent that the machine of myinvention is adaptable for various lengths of coils, and that it is a simple matter to change the stroke or distance of travel of the distributing bar. 165 by this simple adjusting means without the necessity of changing; gears or. substituting cams pro- VldGdWIth diiferent pitch cam faces, 7

Spools, .such as" are illustrated. in dotted lines in-Fig. 4, upon which the convolutions of wire are wound, areprovided with'spool heads between which these convolutio'ns of accuracies in manufacture, the distance be-- tween the spool heads varies slightly, and as a predetermined number of convolutions of wire must be placed thereon, if no provisions were made for adjusting'the distributing bar 165 .to overcome this, it; may be readily seen that if the distance between the spool'heads was a trifle over its fixed predetermined dimensions, that there would e a slight space between the inner faces of the. spool heads and the layers of -wire on the spool, permitting these unsupported ends to loosen, whereas, if this distance is below its fixed predetermined dimension, the

first few end turns of each end of the layers would pile up and form a bulge at each end of the coil which would be magnified as each successive layer isplaced thereon. With the adjustable means for giving the distributing bar 165 an infinite-number of lengths.

" of travel from left to right, and right to left, it is readily apparent that after thefirst layer of convolutions of wires are placed on the spool, the operator can readily observe either of these discrepancies, and in either case, the operator may adjust the distributing bar 165 to increase or decrease the distance of travel fromleft to right, and

vice versa, to overcome this variance of distances between the spool heads by the simple adjusting means which includes the knob 177 and its associated rack 170.

The distance between the spool heads is constant, but due to manufacturing inaccuracies, the heads are placed at varying distances along the core of the spool, so that when they are clamped between the head ofthe winding spindle andthe tail stock T, the first'layer when wound on the. core whole, to the right or left, as the. case may will reveal this discrepancy and I provide the adjustable means associated with the .distributing arm 227 so that the operator by turning the knob 238 the threaded stud 232 will move the block 228 and arm 227 as a be, to center the spool with relation to the v distributing and 227 so that the -c onvol1'1- tions will be placed thereon the full-.adistance betweefi the ispool. heads} without a I piling-up at one end of the core and a space 7 e-tween theend of the layer and the face of the spool head, as would be the case if j this. adjustment were not provided. I I From-the foregoingit isreadily apparent thattlier'otation of the drive shaftnot only causes the windingoffc'onvolutionsl of wire upon the magnet spoohbutfalso causes the movement of the distributor member back.

and forth, and that the'mechanism for accomplishing this result-is; very oompactand enclosed in a casing away from dust and in ury.

If itis desired to-plalcei a difi'erent of convolutions of wire .on the spool,.-;all that is necessary to do is a," change th gearing ratio between the drive shaft and; the distributing member. It will be noted 3 that the armf 112 is provided with a slot 1 so that difierent size gears may be secured. I to this arm in mesh with gears 108 and 106.

The rotation of the drivesh-aft also tran ss -1nits motion to the gearsassociatedwith .the counter mechanism thereby causing the hands of the counter to visualize the number of revolutions of the driving shaft. Thecounter mechanism is alien-closed in' a housing or casing, and is so situated that the visualizing mechanism of the counter devi e is immediately before the operator of'the winding machine. 1

As. before mentioned, the operator can, change the-distance of travel of the feeding mechanism while the winding machine is in operation, and the operator can also adjust the distributing mechanism to feed further to the right or left while the machine is in operation. i

While I have described one particular embodiment of my invention, it is to be understood that the same is not limited tothe specific disclosure, but I aim to cover all the changes and modifications that come.
