I LOOP-WINDING MACHINE.

Application filed February 10, 1925. Serial No.-. 8,282.

Greneri-cally this invention relates towinding or reeling machines, but it more. especially comprehends the type adaptable'for winding loops,-reeling wire, winding field coils, transformer coils,-and the like.

' One objectof this invention is to provide a winding machine embodying a novel type of rigid winding head bar graduated. to facilitate an accurate set-up for length of loop and designed to eliminate possible variations inloop lengths where a plurality of loops arewound at one setting.

Another object of this invention is to design a winding machine embodyinga rigid winding head bar provided withad-justable means for forming varied width loops, means for releasing the tensionon thecompleted loop, and-additional means instantly -detachable to facilitate removal of the loop from the winding pins. 7

Still another object of this invention is the provision of a machine of :the above character embodying a clamping block means associated with the windinghead bar for holding the starting lead wires, eliminating any wastage of wire, and placing inside lead wire or wires in correctposition for finished loop.

A further'object of this invention is the provision of a winding machine of the above thedrive or high speed shaft for facilitating the rapid winding of field coils and for transferring wire from large to small reels.

lVith these and other objects in view, which will become apparent as the description proceeds, the invention resides in the construction, combination and arrangement of parts, hereinafter more fully described and claimed, and illustrated in the accompanying drawings,'in which like characters of reference indicate like parts throughout 7 theseveralfigures, of which:

tory, in that, they were eitherv not accurate 1I1 theividth or length of the loops, or the finished loop was diflicult .to remove, or the Ileadwires could not be expeditiously held in .place, and it .was toovercome the deficienciesof such devices and to provide a winding machine. and Windinghead comprehending novel. and improved features embodying means for perfectly controlling the device, rigid winding head bar, lead clamping trigger-block, variable speed shafts, and surplus power on winding head shaft through special gearing interconnecting the said shafts, and other features that will be more fully explained. as the description proceeds.

that I evolved .the loop winding. machine forming the subj ect. matter of this invention.

In the illustrated embodiment characterizing this invention thereis .shown a frame 1 .formed with cross bars 2 adapted to. support-bearings 3 in which isjournaled power 9 is a left end elevation of Fig.8;

IOU

shaft 4 carrying a-plurality of ratioed pulleys 5, 6, and 7. The said frame 1 isformed with integral upper cross bars 8 adapted to support suitable bearings in which. are mounted the power or high speed shaft 9, intermediate or gearing shaft 10 and.low speed or Winding head shaft 11. Loosely mounted-on the drive shaft 9 intermediate the bars-dare the pulleys 12, 13, and .14,

ratioediinversely to the lower pulleys'5, 6,

and 7, the outer face of the said pulley 14 is adapted to enga e the inner'surface of, brake drum 23 suitably secured to frame bar 8 when member 18- is moved to braking position. The hub 19 is centrally recessed as at 24 to receive the. fingers of the U- shaped clutch fork 25 which is secured to a horizontal pin 25 by means of set screws 25. The said pin passes through holes in the two lugs 25 formed on horizontal plug member 25 which connects the prime memher 1 together at the top just under the hood. The right hand end of pin 25 is beveled for contact with the complement-a1 beveled surface 25 at the upper end of connecting rod 27, the lower end of said rod being hingedly connected to arm 28 secured to the inner end of pedal rod 29 j ournaled through the lower extremity of frame 1 and provided at its outer end with pedal 30. Thus when stepping on pedal 30, the rod 27 is moved vertically contacting the bevel surfaces in a wedging action which forces the clutch fork 25 to the left bringing surface 16 of clutch A in contact with the cone pulley 14 to transmit driving power to shaft 9 .and through the train of gears to rear shaft 11. The clutch fork 25 is connected intermediate its length to frame 8 by coil spring 26 which normally holds surface 22 in contact with the inner surface of brake drum 23, which serves to lock the machine in normal position and prevents it from backing up and slacking up on the wires which are being wound into a loop on the winding head.

One end of shaft 9 extends through the casing 31 to which may be secured a reeling attachment (not shown) for winding field coils and for transferring wire from large to small reels and the like. Mounted on the other end-of shaft 9 adjacent pulley 12 is the small gear 32 adapted to'mesh with the large gear 33 secured to shaft 10, which also carries adjacent gear 33 small gear 34 adapted to mesh with large gear 35 mounted on winding head shaft 11, one end of which extends through the casing 31 and beyond the frame member 8, and externally threaded to engage the internally threaded hub member 36 of the winding head.

The outer end of hub 36 is apertured to receive the headbar 37 firmly secured therein by cap; screw or pin 38 which passes through said hub and head bar and which also serves to secure slotted adjustable plate 39 carrying pin 40 to which the ends of the wiresmay be fastened when starting to wind a loop, in case the lead wire clamping trigger'block hereinafter described is not'emsaid bar. Slidably mountedon the said head 7 bar 37 on each side of the hub 36 arethe winding pin blocks 42 provided with winding pins 43 threadedly or otherwise suitably secured therein and externally; threaded to engage the internally threaded adjustable nuts 44. s V r The trigger-block 45 embodies a pair of spaced circular plate, members joined by an eccentric segmental hub section 46 and a trigger member 47 adapted for insertion between the plates and pivotedly mounted therebetweenby a pin passing through apertures 48 in the plateinembers and 49 in the trigger 47,. A compression spring 50 is mounted on the pin 50 and adapted to seat against the trigger and the hub 46 to normally maintain the notch 51 in engagement with an annular groove formed in the pin 43 predeterminedly spaced from the adjust able nut44. The said trigger-block 45 may be detached from the winding pin 43 by depressing the free end of trigger 47 disengaging the notch 51 from the groove.

The winding pin blocks 42 are provided at their rear ends with projections 42 suitably secured thereto and on which are adapted to be fastened extension arms 52 with their upper ends apertured to receive extension pin blocks 53 secured thereto by nuts 54, the outer ends of blocks 53 carrying winding pins 43, adjusting nuts 44 and trigger blocks 45' exactly as heretofore described in connection with the pinblocks 42, these extensions being provided for use where it is desired to wind odd shaped coils.

Oneside of the winding head bar 37 is graduated on each side of the hub 36, as'at 55, so that the winding pin blocks 42 may be accurately adjusted to provide loops of varying lengths, and. they are firmly secured on said bar 37 by clamping members 56 positioned adjacent saidblocks and connected thereto by bolts 57 carried by said members 56 and adapted to threadedly engage the blocks 42, the said. clamping members being secured to the bar 37 at any desired points by bolts 58.

In order to expedite the removal of the finished loop 59-fro1n'the winding pins 43 it. is advisable to haveone of the pin blocks 42 independently adjustable with respect to its adjacent clamping or anchoring member 56 which is eifectedby substituting'for the: bolt 57, rod 60 having one end threadedly or loo otherwise secured to block 42 slidably extending through clamping member 56 with its outer end pivotedly secured to cam lever,

' mounted on one of the winding pins L3, similar to trigger block 45 heretofore described, and embodying an integral trigger mechanism 68 positioned directly under face member 64 of body portion 65. A center bore 66 extends through members 64, 63 and adapted to receive the pin 43 when the said block is operatively positioned thereon, the operation of the trigger mechanism being similar to trigger blocks 45.

The reduced end'of body portion 65 is formed with an integral clamping or vice jaw 67 and is transversely or interiorly recessed, one side of which is closed. by the detachable plate 68,, the said plate and the opposite side being apertnred to receive the adjusting screw 69 provided with operating knob 70. Mounted on'said screw 69 within the said opening or recess isthe flanged nut 71 adapted to engage both sides of the adjustable clampingplate 72 slotted as at 73 and provided with handle 74 by which it may be adjusted vertically. The nut 71 is internally threaded to engage the threads 75 of the screw 69, so that by actuation of the said screw the plate 72 will move towards or away from the jaw 67, gripping or releasing the lead wire or wires 59 as desired.

The other end of body portion 65 is constructed with a substantially yoke-shaped member 7 6 hinged to said body portion, as at 77 and carrying screw 78 provided at its outer end with hand wheel 7 9 and its inner end with clamp plate 80, the said yoke memher 7 6 being locked in operative position by lock-pin 81 extending through the body portion 65 and contacting with the under surface of the free end of the said yol'zemember as at 82, the said screw 81 carrying coil spring 83 adapted to hold the said pin in locked position when the yoke member 76 has been brought to operative position and the plate into clamping contact with the lead wires 59, as clearly shown in Fig. 10 of the drawings.

lVith the types of winding heads heretofore employed it has been necessary when commencing a loop to fasten the end of the .wire to some part of the mechanism which had to be straightened and positioned to provide a correct lead, with a consequent loss of time and material which difficulties were materially increased when a plurality of wires were simultaneonsly wound, and it was to overcome such deficiencies that Idesigned the starting lead wire clamping mechanism above described.

From the foregoing it is apparent that I have designed a coil or loop winding machine embodying many novel features in advance of those now in use, of great adaptability, simple in construction, efficient for the purposes intended, and the operation of which it is thought is sufficiently clear from the above description to render furticr explanation unnecessary.

Although in the foregoing, certain elements have been set forth as best adapted to perform the functions allotted to them, nevertheless,it is to be understood that various minor changes as to form, substance, etc, may be resortedto within the scope of the appended claims without departing from or sacrificing any of the. principlesof this invention.
