coLLAPsIBLEcoEE ron USE IN `TEE motors and the like, from )fiat wire.` Second; to provide animprove'd collapsible coil Winding core, whichcan be readily set up or is quickly knocked-down after the coil has been formed thereon. Third; to provide an improved coil Winding core which is adapted for use as an attachment for lathes.
Further objects, and objects relatingtov structural details, Will delinitely appear from the detailed description to follow..v
I accomplishy the objects of my invention by the devices and means described in `the following specification.
The invention is' lclearly defined and pointed out in the claims..
A structure which is a preferred einbodimentvof my invention isclearly illustrated in the accompanying drawing,`form ing a part of this specification, in Whichz' Figure I is a detail'side elevation of a structure embodying the features of my in-` vention, the chuck and tail stock of a lathe being shown in conventional form. Fig'. II is an enlarged detail sectiontaken on 4a line corresponding to line 2-2 of Fig. I, the parts being shown with a coil partially mounted thereon. Fig. III is a detail side elevation partially and vertically central section on a line corresponding to line 33 of Fig. II. Fig. IV is a transverse section corresponding to that of Fig.'II, with 'the side reachesof the coils hammered down against the sides of the supporting bar 3,
that being the last step or operation inv forming-the coil on the core.
Referring to the drawing, 1 represents the chuck of a lathe and 2 the tail stock.
My improved Winding core consists of a supportin bar 3, which is, in the structure illustrate rectangular in cross section, 1s
" provided with longitudinal grooyes ligand specification of Letters Patent. vApparati@ fixed May e, 1911.
. formedv by the core MANUFACTURIE OF COILS.
Patented sept. 5, 191i. serial No. casetta'. bemg inclined as illustrated in Fig'III The bar l, is .provided with a chuck shank at one end and vvitltl a bearing?"` at' the other.'
A plurality of idis'k like core members 8 having 4hub-like?portions 9 on onevk side fand inwardly projectlng lugs ,1Q on their .inner edges are provided. The corefmembers 8 are arranged in sets 'upon' the clamping bolts 11 and when clamped together "coact to form grooves as l2. The tapered key 13 is arrangedfin the groove 5 andr serves tio ,snpporty the'set of core members arranged in tha'tfgjroove. In use the core members lare, 'assembled on for the strands ofthe coil, j i
their clamping bolts land' larranged in' the4 j supporting barn: being] suitably Vretained therein by the Coil itself. AAdditional means for retaining the parts Itogether' lcan beprof'- vided if desired. "t

The
wire tobelwound is fedfinto the coil groove members as the-bar 3` is revolved. I have not attemptedlto use'sutiicient tension in Windingv the'c'oils to cause ,A the f coils",.tof'lie'dlat1l the side reaches of against thev sides of the. supporting ban-ff In practice, after the coil is ivou'ndas shown in Fig. II, I press or hammer the.
sides of the coil down` against the sides of the bar as shown in Fig. IV. The material used being ordinarily of soft copper this is easily accomplished. After the sides of the coil have been iattened or pressed against the sides of the supporting bar as shown in Fig. I V, the key 13. is removed.
being slipped from This permits the -`coi1 thecore bar.- The clamping bolts 11 are then removed and the core members fall from or may be lquickly removed from between the strands of the coil. when removed from the core ordinarily have avendency to twist on account of the hardening of the metalLresultin from the bending. In practice I relieve is by an- -15 The wire is fed o1" delivered to 1fhejvin-d,
The coils,
nealing. By the aid of improvements .I am enabled to produce very rapidly, cores `provements in a simpleembodiment. I aml aware that the improvementsare capable of y having hub-like I considerable modicationin structural ldetails, but as such modification will no doubt be readily understood by thosel skilled in the art to which this invention relates I have not attempted to illustrate or describe the same herein.
Having' thus described my invention, what I claim as new and desire to secure by Letters Patent is:
l. In a device ofthe class described', the combination of a bar having longitudinal grooves in its edges, the bottom of one of the grooves beingv inclined, disk like core members having hub-like side and groove engaging -lugs on their inner edges, bolts bers together in setsyand a tapered key said groove having the inclined bottom.
- 2. In a device of the class described, the combination otl a bar having longitudinal. ooves in its edges, disk like core members ortions on one side and ugs on their inner edges for oove engaging and l' bolts for clamping said core members together in sets. y 4
3. In a device ot the. class described, the
I combination of a bar having longitudinal -grooves 1n its edges,
grooves in its edges, one oit the grooves havaninclined bottom, a plurality of core lugs at removable clamping bolts fon' said core members, said core members coaoting when assembled to provide grooves for the coil when arranged on said bolts, and' a tapered key adapted to coact with'the inclined bottom of said groove.`
4c. Iny a device of the class described, the combination of aA bar having longitudinal a plurality of core members having groove engaging lugs at portions on one i for clamping said core memfor the coil when arranged on said core.
5. In a device of the class described, the
core vmembers havin hub-like `portions on one side and remova le bolts for clamping said core members together in sets, said core members being spaced by said hub-like portions thereof to receive the strands of a coil therebetween, said sets of core members being removably mounted on said bar.
6. In a device of theclass described, the combination of a supporting bar, a plurality of c ore members, and removable clamping bers together in sets, said corev members being adapted to receive the strands of the vcoil therebetween when arranged on said `bolts, there being two sets ot said core members mounted on `said bar.
7 In a device of, the class described, the
of core members, and removable clamping bolts for said core memberstogether 1n sets,
combination of a supporting bar, disk likey bolts for securing said core mem-` combination of a suppqrtingbar, a plurality said core members coaet'ing to provide coil grooves when arranged on said bolts, there being two sets of said core members mounted on said bar.
In witness whereof, I have hereunto set my hand and seal 'in the presence of two witnesses.
