I have found themechanism of invention .highly practical in iiiaiiofabtre and; se, but I desire 'that the embodiment of my invention shown herein shall be considered in the illustrative sense rather than in a limited sense.

Referring to the drawings in more detail reference character I designates the -base of the equipment carrying the motor support 2 providing mounting means for the driving motor 3 which drives live spindle 4. The motor 3 may be of small size of either D. C. or A. C. type operating from conventional 11.0 volt power sources. The live spindle 4 connects to the shock absorbing fiexible coupling 5, the opposite end of which connects to the driven shaft 6. Driven shaft 6 has a hand wheel control 1 secured thereon for revolving the driven shaft 6' under manual control. The driven shaft 6 is journalled in bearings in upwardly extending members 48 and 9 supported on base plate I3 secured by suitable means I4 to the base I. ing members 8 and 9 are interconnected by a plate portion I2. Base plate I3, plate portion I2 and the upwardly extending members 8 and 9 may be formed as a single casting .serving vas a housing for the adjustable stroke controlling mechanism. The front of the interconnecting plate I2 is represented at I2b representing the front of the casting which' includes the base plate I3, intermediate .plate I2 andV upwardly extending members 8 and 9`.

The bearings formed in the upwardly extending members 8 and 9 serve asv journals for the driven shaft 6 which is confined in a predetermined position by means of adjustable collars IIland I I which may be set in position on driven shaft 6 to limit end-.wise movement of driven shaft 6. The driven shaft 6 is provided with a worm I5 intermediate the upwardly extending members 8 and 9 and the driven shaft 6 extends through upwardly extending member 9 and is reduced in sectionat. I6 and again at I1 to form an arbor for receiving the bobbin L to be wound. l

The worm I5 engages a worm wheel I8 keyed to which is a transverse shaft I9, united by key and key-way indicated at I9a, which is journalled in sleeve bearing mounted in the support I2 which extends ,between upwardly extending mem- bers 8 and, 9. The sleeve bearing 20 is provided with a lubricating aperture 20a alignable with the lubricating aperture I2a in the intermediate plate I2 for maintaining the shaft I9 lubricated at all times. The shaft I9 extends beyond the front. of the face-plate I2b and through the indicator dial 2I and is secured there to thevferrule 22 to which is attached the radially extending pointer 23. The indicator dial 2I is fastened to the face I2b of intermediate plate I2 in any suitable manner such as screw 2Ia and carries .graduations thereon for indicating the number of turns on the bobbin, properly compensated for the variation in diameter of the bobbin as the size of the bobbin increases during the progressive winding process.

The transverse shaft I9 carries Va plate-like cam 24 on the end thereof and secured thereto by a readily removable set-screw 25 shown more clearly in Fig. 6. The screw 25 is readily removable and replaceable to permit the interchange of the plate-like camrfor the selective control of strokes of different lengths. 'I'he plate-like cam is of cardioid shape which I have employed to secure the reversal in movement of the guide mechanism for the wire or textile being distributed along the bobbin and to ensure reversal of the stroke at the proper instant. To provide for the entire 360 of movement of The lupwardly extendthe plate-like cam 24 of the various increasing sizes which may be applied to the winding mechanism for the winding of bobbins of various lengths I form the upwardly extended member 8 and 9 with inwardly curved recesses shown at 26 and 21. Similarly base plate I3 is recessed at 28 to permit sweep of the plate-like cam 24 or the associated cams of the increasing size of the set of cams employed for the winding machine. In controlling the stroke for bobbins of different lengths plate-like cams of a throw almost suiicient to approach the limiting distance allowed by the recesses 26, 21 and 28 Y may be applied to'the end of shaft I9 so that adequate clearance is provided in the mechanism initially.

The stroke control mechanism includes bar V29* of polygonal section which is controlled by the plate-like cam 24 and is mounted for reciprovcative movement in vertical extending members 8 and 9 which are recessed at 30 and 3I in section conforming to the polygonal section of the bar 29. Bar 29 is confined in the recesses 30 and 3| by removable strip members 32 and 33 removably securedin position by screws 34 and 35. When it is necessary to substitute platelike cams for the cam 24 strips 32 and 33 are readily removable whereupon access is immediately had to the cam mechanism for the interchange of cams and the application of a cam of proper size. However, by virtue of the individual adjustment means 36 and 31 which I provide' on bar 29, one plate-like cam may be made to serve over a wide range of stroke adjustments. thereby. minimizing the number of cams to be utilized.

The adjustment means36 and 31 comprise rod members having screw threaded ends extendable through longitudinally disposed slots 38 and 39 in the bar 29 and projecting in the path of the plate-like cam 24 as shown at 36a and 31a. A'I'he rod members 36 and 31 are clamped in a selected position by means of bolts with'threaded ends Vshown-at 4|Jand 4I. `|I'hus the ends of the'rod 'members at 36a and 31a may be spread apart or moved closer to embrace the peripheral edge of plate-like cam 24 or any one-of a series of 'cams of larger or smaller size which may be 'installed for controlling the length of the stroke.

The end of the bar 29 is screw-threaded as represented at 42 for the engagement of a pair of knurled adjusting nuts 43 and 44 which may be manually adjusted to move the wire or thread guide member 45 to a select position with respect to the bobbin to be wound. The wire or thread guide 45 comprises a plate Vmember which is wrapped loosely around the screw-threaded portion 42 of bar 29 and terminates' in a tapered tongue 45a which carries a pair of yieldably mounted wire or thread'guides represented at 46 and 41. The wire-or thread guide 41 extends across the path'of the wire -or thread guide 46 as shown. A

In4 Figs. v1--16 I have shown more clearly the manner of assembling the bobbin on the arbor I6. In Fig. l0 I have illustrated the insulated tubular core 48 for the bobbin having a flanged end 48a`which'is formed to provide an abutment stop for a coil end 49 of insulation material. The tubular core 48 also has a coil end5IJ of insulation' material slipped thereon before the end of the `tubular core 48 is rolled over to form a flange as represented in 48h. The coil form thus provided is slid upon the end of the arbor I6 and abuts against the. shoulder ISa intermediate asta-evs for the end of the ilange 4817 of the tubular core of insulation 48 and abutmentlfor the end 55 of insulation material as shown clearlyin Figs. 1 and 8.- 'With the support thus afforded for the coil vend4 50 with respect to thetubular coil formr 48 the ,detachable end flange 52 is moved into positon over the terminating end I1 of the arbor i6., TheY end flange 52 has an annular recess 53 forming the end thereof and slotted as represented at 54.

permits insulation member 49 to -be seated directly against the end liange as represented in Figs. 1 and 8. I provide an annular ring member 55 which embraces the flange 52 and is provided; with a set-screw 56 therein with a radially extended pin 51 thereon adapted to extend through a radial aperture 58 in end flange 52 and project into the groove I1a in end section l1 of the arbor and effect an interlock with the bayonet slot 11b in the terminus of the arbor l1.

The flange 52 is pierced at B0 by an aperture which facilitates the threading of the wire 6i therethrough at the start of the Winding operation. The assembly of a bobbin on the arbor I5 is thus greatly simplified as it is only necessary to slide the tubular coil form 48 on to the arbor I6 with the coil end 49 in abutment with the flange 48a, and coil end 50 in abutment with flange 48h. The coil end 5U abuts against the cylindrical sleeve 5| with the flange 4817 projecting into the annular recess 5Ib in the end of the cylindrical sleeve 5|. Similarly, the flange 43a extends into the annular recess 53 in end flange 52 when end flange 52 within ring member 55 is detachably positioned on the terminating end I1 of arbor I5.

In order to commence a winding operation the end of the Wire from the supply reel is threaded through the wire or thread guides 46 and 41 and threaded through the slit 49a in the insulation member 49 and through the aperture 60 as represented at 6| in Fig. 7. The motor 3 is then started and the wire is fed automatically to the bobbin. As each layer is completed the path of travel of the wire guides and 41 is reversed and the succeeding layer wound in position. This automatic reversal of the movement of the wire guides 46 and 41 is automatically controlled by the movement of the cardioid shaped cam 24 until the winding of the bobbin is complete. The free end of the wire is then brought out through the eyelet 62 forming the securing means for the hook shaped lug 63 which is fastened to coil end and looped around the securing clip G4 on cylindrical sleeve 5I Where the end of the supply reel may be severed. The completely wound solenoid is then readily removed by quick rotation of the ring member and pin 51 with respect to the interlock connection with the bayonet slot 11b and the removal of the ring member 55 and the enclosed flange 52. This permits the withdrawal of the solenoid from the arbor IB and the replacement of a new solenoid form ready to receive a subsequent winding.

The Winding process is very readily completed and inasmuch as the motor drive for the Winding machine is directly connected with the gear mechanism the entire unit is made very compact and the control thereof very greatly simpled.

Adequate reduction in speed is secured by the y Thisfacilitates the entry of the. flange end 48a of the tubular'insulator 43 and ic A v each substitutedliat camv 24 I provide for adjustment of thevrod members 36 and 31 Which apaisement sfjiwennL ana [wt-in when drive ;iaine .dii-ringe@ viining', Qperaiion in propor- .tigntothe speed of rotation of the bobbin bftainedby the direct motor drive arrangement.
