This invention relates to new and useful improvements in apparatus for winding and completely forming electric coils such as are used in semi-closed slot, three or two phase electric motors of various sizes and speed.
The principal object of the present invention is to provide an apparatus upon which first, a coil can be wound, and secondly, formed to the desired shape in which the same will be used in the electric machine.
Other important objects and advantages of the invention will become apparent to the reader of the following specification.

Figure 16 is an end elevational view of the finished coil.
Figure 1'7 is a top plan view of the finished coil.
Referring to the drawings, wherein like numerals designate like parts, it can be seen in Figure 1 that the apparatus consists of end supports, each end support consisting of a pair of upwardly tapering frame structures 55, these frame structures each formed with brace Figure 7 is a fragmentary detailed sectional means and having their front portions anchored as at 6 to a base 1. Suitable bridgemembers B are provided between theframe structures to support bearings 9 through which the vertical shaft I0 is disposed. There is a vertical shaft 5 at each end of the apparatus and the horizontal drive shaft H extends between the end supporting structures and through bearings l2 in the end supporting structures. The ends of the shaft II are equipped with bevel gears l3 which 10 mesh with bevel gears H! at the lower end of the shafts [0. The upper ends of the shafts l0, are provided with bevel gears I5 which mesh with bevel gears IS on the shafts l1 and, 18 which are journaled through bearings H! at the upper porl5 tions of the said end supporting structure.
A belt 26 is trained over the pulley block 2| on the armature shaft of the motor 22 and also over the pulley block 23 on the drive shaft II, and obviously suitable clutch means desired may be used in conjunction with this belt or in the drive shaft II.
The shaft I1 is provided with the head porti0n'24 securing the block 25 through which the elongated shaft 26 is disposed, the intermediate 25 portion of the shaft being secured to the block 25 by the set screw 21. As is clearly shown in Figure 6, the bar 26 is grooved inwardly from each end thereof as at 28 to a point adjacent the intermediate portion thereof. 30
At each side of the block 25 the bar 26 extends through a block 30 and each of these blocks 30 has a bore 3| therein at right angles to the bore receiving the bar 26. Each of these blocks 30 also has a set screw 32 for disposition into 35 the corresponding groove 28. A bar 33 extends through the bore 3| of each of the blocks 36 and each of these bars has smooth-ed side portions extending toward the ends of the bar from the intermediate undisturbed portion 34, 40 and these flattened portions are disposed through bores 35 in blocks 36. Set screws 31 engaged in the blocks 36 bear against the fiat sides of the bars 33.
Laterally disposed lugs 38 serve to receive the 45 ends of the elongated coil engaging rods 39, each of these rods 39 carrying a plurality of collars 46 serving as coil spacing means.
The shaft 26 outwardly of the blocks 30 carries the blocks 4|, one at each end portion of 50 the bar 26. Each of these blocks 4| carries a set screw 42 for disposition in the corresponding groove 28 of the bar 26 and each of these blocks 4| is bifurcated as at 43 to receive the corresponding end of the rod 44. Each of these rods 44 carries a sleeve 45 from which a plurality of pins 48 extend in substantially the same spaced relation as the collars 40 on the rods 39. As shown in Figure 10, the rod 44 is provided with a tongue 4'! for disposition into a longitudinally extending groove 48 in the sleeve 45. A set screw 49 on the sleeve can be driven against the rod 44 to prevent longitudinal adjustment thereof.
The remaining ends of the rods 44 are also equipped with the blocks 41 adjustably disposed on the grooved short bars 50.
Each of thes blocks 4! carries a pair of pins 5l5la which extend through a slot 53 in the corresponding end of the rod 44 to'secure the rods 39 against pivotal and endwise sliding movement and obviously to permit the-apparatus to swing in forming a coil, one of these pins-must be removed at each of the blocks 4| whereby the wire carrying rods 39 may pivot and slide endwise.
vAs shown-in Figure 8, the short shafts .50 each has its end poritonsprovided with circumferentially extending grooves forreceiving the set screw- 59a in the arm. 52 and also the set screw 53' in the'block 54, theblock 54 being formed with a bore 55 at right angles to the opening'receiving the bar-:59 for supporting the blocks 56 which carry the'lugs -5'l for receiving-the re- .maining ends of the rods 39. Set screws 58 on the: blocks 54engage .the rod 59 to prevent selfadjusting thereof.
The longitudinally groovedbar-BO is carried by the head structure 5! .on aforementioned shaft l8 and this part9 is disposedthrough the end portions of thearms 52 andthese arms are .held in place by set screws .62.
It can be seen that the lugs 5'l are swivelly connected as at 65 .to the corresponding blocks 56 through whichlthe bar 59 extends, the rod 39 being providedwith-al reduced portion 66 secured in the lugs 51 by set screws Bl.
-Obviously, in--the operation of the apparatus, thewire is-started-onto the apparatus and the apparatusis rotated until all of--the spaces between the lugsand pins havebeen filledwith coils. Subsequentlythe set screws and certain of the'pins- 5l5la canbe removed to permit the apparatus to be tilted down. in the manner shown in Figure 3, in which action the coils 68 are brought to the desired-form as shown in Figures-15,=16 and 17; I
To hold'the coils against slipping over the pins andcollars, it can-be seen that the collars are formed with extensions- 69 recessed as at 10 for receiving the lock rod all which can be held in place by a cliptype spring 12. -These clips and rods can be removed when: the coils are to be removed.
*-While the foregoing specification sets forth the invention in specificterms, it is to be understood'that numerous changes in the shape, size and materials maybe resorted-to without departing from the spirit and scope of the invention as claimed'hereinafter.
