Patented Mar. 28, 1933 UNITED STATES PATENT OFFICE THOMAS CHARLES HUGHES, or nEwoAs'rLE-UroN-TYNE, ENGLAND, ASSIGNOR TO LARMUTI-I & BULMEE LIMITED, or MANCHESTER, ENGLAND BOBBIN 0R SPOOL WINDING MACHINE Application filed August 29, 1931, Serial No 560,110, and in Great Britain September 27, 1930.

This invention relates to bobbin or spool winding machines employed for winding wire, thread, cord, rope or the like material on to bobbins or spools, and is directed more 5 particularly to the bobbin, spool or material guide reversing mechanism for laying the windings side by side in superposed layers.

A bobbin or spool winding machine in accordance with my invention has bobbin, spool or material guide reciprocating means which comprises a shaft on which are a loose, driven gear wheel and a fast gear wheel both in mesh with a pinion mounted on a carrier disc which is loosely mounted on the said shaft, positively acting means being provided to prevent rotation of the pinion wheel automatically by locking the ring against rotation and permit rotation atwill, whereby the shaft is caused to rotate in one or the other direction whilst the loose driven gear wheel is rotated constantly in a uniform direction.

Variable speed gearing may be provided in the means employed to drive the driven gear wheel, whereby the speed of the reciprocatory movement can be changed at will.

' The means for controlling rotation of the pinion may comprise a rotatable member having stop means adapted to be acted on by a displaceable abutment and carrying a locking tooth adapted to engage the pinion, spring loaded means being provided to maintain the locking tooth in engagement except when the abutment is caused to act on the said stop means.

My invention is illustrated in the accompanying two sheets of drawings which also illustrate its corporation in a winding machine.

In the drawings Figure 1 is a front elevation of a bobbin or spool winding machine.

Figure 2 is a plan view thereof.

Figure 3 is a detached end view in section of details.

Figure 4 is a detached side View in section of a detail, taken on a line corresponding with the line H of Figure 3 regarded in the direction of the arrow.

with a nut 8 which is engaged by a screw thread 5 provided on a part of a rotatably mounted shaft 6.

A bevel wheel 7 is compounded with a spur wheel 9 and both are mounted on the shaft .6 to rotate independently thereof.

A bevel wheel 10 is mounted on the shaft 6 to rotate therewith and the shaft 6 has -mounted on it between the two bevel wheels 7 and 10 acarrier disc 11 which is free to rotate independently of the shaft 6. The disc 11 is provided with a gap 12 in its periphery and a bevel pinion 13 is situated in the gap 12, the pinion 18 being mounted rotatably on a radial stud 14 provided on the disc 11 and situated in the gap 12. The teeth of the pinion 13 mesh simultaneously and constantly with the teeth of the two bevel wheels 7 and 10.

The disc 11 is surrounded peripherally by a ring 15 which has a block 16 attached to its inner periphery by a screw 17. The block 16 has a locking tooth 18 adapted to mesh with the teeth of the pinion 13 and extends into a gap 19 provided in the periphery of the disc and communicating with the gap 12. The ring 15 is connected to the disc 11 by screws 20 which extend through slots 21 in the ring, whereby a limited amount of relative circular movement between the disc 11 and the ring 15 is permitted. The ring 15 is also provided with an inwardly directed projection 22 which extends into a cavity 23 in the periphery of the disc 11 and is acted on by a compression spring 24 provided in the cavity 23 under initial compression.

The ring 15 is provided externally with one or more suitably positioned stops 25.

An abutment 26 is provided on a tumbler lever 27 which is movable about a pivot 28 and is acted on by rollers 29 and 30 provided on a rod 31 which is slidable to enable the abutment 26 to be brought into and out of the path of the stop or stops 25.

The bobbin spindle 3 is suitably coupled, for example by means of a slot and projection coupling 32 to a spindle which is mounted in a bracket 34 on the carriage and slides in a hollow mandrel 35 mounted on a stationary driving head 36. The spindle 33 is connected to the mandrel 35 to rotate therewith and the mandrel 35 is provided with a fast pulley 37 and loose pulley 38 over which passes a driving strap under the control of a striking fork 39. The mandrel 35 is connected by gearing 40, 41, 42, which comprises one or more change wheels, to the said pinion wheel 9.

The rod 31 is provided with adjustable collars 43, 44 adapted to be impinged against by the carriage 4.

In operation, when the strap is on the fast pulley 37, the mandrel 35 rotates the bobbin 1 through the spindles 3 and 33 and also rotates the shaft 6 and therefore the bevel wheel 7. The compression spring maintains the ring 15 in the circular position shown in Figures 3 and 4, relative to he disc 11 so that the locking tooth 18 is forced into engagement with the pinion 13 and thereby locks the pinion 13 against rotation. The disc 11 and ring 15 are however free to rotate. Owing to the locking of the pinion 13 against rotation, the bevel wheel 10 is locked to the bevel wheel 7 which in consequence of its rotation by the mandrel 35, rotates the shaft 6 and thereby causes the nut 8 and carriage 4 to travel in one direction. Thus the bobbin is traversed in one direction whilst rotating, the spindle 33 be ing free to slide in the mandrel 35 and therefore not interfering with the movement. On operation of the rod 31 by the action of the moving carriage 4 on the collar 43, to bring the abutment 26 into action by oscillation of the lever 27 due to the action of the rollers 29 thereon, the stop or one of the stops 25 impinges against the abutment 26 and thus rotation of the ring 15 is stopped.

The disc 11 however continues its rotation until it has displaced itself circularly against the action of the spring 24 for a predetermined distance and thereby disengaged the pinion 13 from the locking tooth 18. The pinion 13 is now free to rotate on its own axis, but it can no longer revolve about the axis of the shaft 6 because the ring 15 and disc 11 are held by the abutment 26 against rotation. Therefore the continued rotation of the bevel wheel 7 in the same direction causes the pinion 13 to rotate and the pinion 13 rotates the bevel wheel 10 and therefore the shaft 6 in the reverse direction, whereby the nut 8, carriage 4 and rotating bobbin 1 are traversed in the opposite direction until the carriage by its action on the collar 4 displaces the rod 31 in the reverse direction and thereby causes the roller 30 to oscillate the lever 27 in the reverse direction and thereby cause the abutment to leave the path of the stops 25. The ring 15 is then free to rotate relative to the disc 11 and the spring 24 returns the tooth into engagement with the pinion 13, whereupon both the ring 15 and disc 11 rotate and the carriage 4 is thereby caused to again traverse tie bobbin in the first mentioned direction. By this means the material passing through a stationary guide device 45 can be wound on the bobbin 1 in superposed layers of adjacent coils. shown in the positions which they occupy the moment after the abutment 26 has come into operative position to stop the ring 15, but before the disc 11 has moved relative to the ring 15.

The material passes from the swift over a system of guide pulleys 46, 47 and 48 in the stated order before it reaches the guide device 45, the pulleys preferably being arranged so that they operate equally well with the swift at either side of the machine.

The pulley is shown in position for operation when the swift is at the rear side of the machine. If the swift is at the front side the pulley 46 and its stud 49 are trans ferred to the boss 50. The pulleys 46, 47 and 48 are so arranged that the material 2 passes over the pulley 46, then over the pulley 47 and then over the pulley 48 to the guide device 45 and therefore is formed by them into a coil or loop in the bight of which lies the pulley 47. The pulley 47 is arranged on a slidable block 51 which has a roller 52 adapted to act 011 a lever 53 fulerumed at 54 and connected by a link 55 or other suitable mechanism to the striking fork 39 which has a pivotal spindle 59. The pulley 47 is so weighted by the block 51 that it maintains a predetermined position against the tendency of the resistance set up by the usual swift brake to shorten the coil or loop and thereby move the pulley 47 upwards. When this resistance is exceeded or when the material ceases to leave the swift for any other reason than exhaustion of material, the increased resistance acts to shorten the coil or loop and thereby move the pulley 47 upwards, thereby causing the rollers 52 to act on the lever 53 and thereby actuate the striking fork 39 to shift the belt onto the loose I pulley 38 and thereby stop the machine until the material is freed to run under the correct resistance or tension.

A hand lever 56 is provided to operate the fork 39 by hand when desired.

In the fi ures the arts are A spring plunger 57 may be provided to lock the rod 31 yieldingly in its two end positions by cooperation with a V-block 58 on the rod 31.

I claim In a Winding machine, a direction reversing mechanism for laying windings side by side in superposed layers, comprising in combination, a reversing shaft a bevel Wheel secured to the said shaft to rotate therewith, a bevel wheel mounted loose on the said shaft, a driven gear wheel provided on the second named bevel wheel for driving the same direct, a carrier disc mounted loose on the said shaft between the said bevel wheels, a bevel pinion rotatably mounted on the disc and in constant mesh with both of the said bevel Wheels, a ring mounted on the periphery of the carrier disc and circularly displaceable thereon, a tooth fixed to the ring for engaging and locking the bevel pinion against rotation, spring means on the ring for yieldingly holding the tooth in locking engagement with the bevel pinion, external stops on the ring, and a displaceable abutment on the mechanism for cooperation with the said stops in positively locking the ring against rotary movement and thereby disengaging the said tooth against the action of the spring means.

In testimony whereof, I have signed my name to this specification at the city and county of NeWcastle-upon-Tyne, England.

THOMAS CHARLES HUGHES.
