SPOOL HEAD.
APPLICATION FILED MAR. 24, 1910.

UNITED STATES PATENT omen CHARLES E. SMITH, or extreme, nannvois, assrenon 'ro nannoee swrronsoann AND SUPPLY COMPANY, or cnroaeo, ILLINOIS, A oonronanoN-or ILLINOIS.
SPOOIi-HEAID.
To all whom may concern:
Be it known that I, CHARLES a citizen of the United States, residing in Chicago, county of Cook, and State of Illiv face 23 as shownby the dotted lines of the spool head 2 in Fig. 1. .The core 3 may be fastened-in the head Q in-any suitable-inannois, have invented a certain new and useful Improvement in Spool-Heads, of which the following is a specification.
My invention relates to spool heads for electro-magnets, induction coils of all kinds, or any spool having a winding on a core with heads inclosing the ends thereaf, and
more particularly to that type in which the j terminals or ends of tl1)e windings are brought out through the s 001 head.
Heretofore it has been-necessary to drill holes in the spool heads for each different diameter of winding, and the object of my invention is to secure a spool head in which the terminals of any diameter of Winding may be brought through without the use of a difierent opening or different spool head for-each diameter.
In applying my invention to any spool, a single 0 ening in the spool heads :may be used to ring out the terminals of any diameter of winding.
Referring to the drawings,.Figure 1 is a side elevation of a spool, showing the core and the two headswith their terminal clips, but without any winding; Fig. 2 is an end elevation of thestructure shown'in Fig. 1 showing the openings for'theterminals of the windings; 3 is "a vertical" longitudinal section of Fig. 2. through the section 1ine-33 showing the two spool heads, the
core and two windings about the core with.
the terminals of theoutside winding extndingthro'ugh the openings in the spool heads; Fig. 4 is a vertlcal longitudinal sec.-
tion of Fig. 2 along the section line and difi'ers from Fig.8 inthat the terminals of the inner winding are shown lea-ding g in thespool heads; Fig. 5 is a perspect ve view of one of the heads of the spooh Referring to Fig. '1,
through the openin 1 and are the spool heads which are-preferably made of fiber,- although any insulating material may be 'f-nsed, 3 is the core, and 4 and 5 are the terminal clips: which are made of brass to r th 12 1 head 1.

Application filed March 24, 1910. Serial No. 551,322.
Fig. -2' shows the spool head'2'with the core 3 and the small openings Sand 9, the upper and lower sides of which diverge from the outer surface 22 to the in1'1ersurnor. It will be readily noted that the open ing 9 is close to the core --3, while the opening 8 is at a greater distance from the core.
:ing. therethrough. are connected. i there were but one winding on the spool the terminal or end of the layerne-xt to the corewould come through the opening 9 while the.
terminal from the outer layer of; theiwindv ingwould 'come through the opening-8,.
would preferably arrange the terminals as my invention as shown, .a 1thoughiI do not showninFigsfii and}. ."It is obvious'that. .the upper and loyver sides of the openings-8 -and 9 may be parallel, but I prefer to apply the construction shown in; Fig. 2 it may be determined by .an inspection. of the outside of the s all where. anyfcertainterminalf or;
end lea s to,'that; whethe'rit .leads 'to an inner-foronterlayeif where there is onlyone winding,-'of w h outer. winding here thereismore thanone winding? v a v InF-ig', the terminalsxlO and '11 of the outer wi ding 12 are shdwnleadingthrou h their respective openings" 8-" 'and131 in t; e d .While in-,this view I have Ieading-thrbugh theop'enin'gs, it oan be rea ily seen thatthe same openings 'would serve etheritf leads to an inner or the inner winding li-ifdesired. From an examination ofthis figure it can be readily seen that the slottedropenin'g's :8 and 13 could serve as outlets for theterminals or ends of any diameter-off winding which may be fplaced onthe' spool withinfthe range of the opening. In other-words, a winding of any number of layers within the range ofthe large end of the opening maybe placed upon the spool and an end 'ori terminal 'taken through the opening'- at: aipointadj acent to enx-ley net hs w ndma In Fig. 4.- I have shown the terminals 15 and 16 of the winding 14 leading out through their respective openings 9 and 17, but it can be readily seen that these openings could also serve as outlets for the terminals of the outer Winding 12.
While in the Figs. 3 and 4 I have shown the slotted openings 8 and 9 with their diverging sides at different distances from the center of the head 2, they could as readily be placed at different points of the same radius of the head. Neither do I Wish to be limitedto the exact form of opening shown,
as the main feature of my invention is to have an openin in the spool head next to the winding whlch is large enough to receive the terminals or ends at a point adjacent any layer of the winding of any diameter which the spool head is adapted to inclose.
Fig. 5 shows the slotted openings 8 and 9 of the spool 'head, the upper surface of the figure being that side which is placed next to the winding. For fastening the spool to any surface, a screw is passed through the hole 19 and into the surface to which the spool is to be fastened. Holes 20 "are for inserting the screws which fasten the terminals 4 and 5 to the spool head. The hole 21 is for the insertion of the core 3. The dotted lines in this figure show the manner in which the sides of the openings 8 and 9 converge in passing through the spool head 2 from the upper to the lower side of the figure.
What I claim as new and'desire to secure by Letters Patent is:'
1. A spool comprising a core, a spool head secured to each end of said core, an o ening passing through one of said spool hea s from the inner surface to the outer surface thereof, said 0 ening being adapted at the said inner sur ace to receive anend or terminal of any diameter of winding thesaid spool head is adapted to inclose. i
2. A spool for electromagnets' having a windin and a ,spool head inclosing the ends thereo the said spool head having a slotted aperture adapted to "receive an end of any layer of the winding. I
3. A spool for electromagnets, a winding of a definite number of layers on said spool, and an aperture in a head of said spool adapted to receive an end or terminal of any a core, a winding having a plurality of lay-- ers about said core, a spool head secured to said core having an inner and an outer surface, an opening extending through the said spool head, said opening being large at the inner surface and small at a definite point i at the outer surface of said spool head, said opening at the inner surface being adapted to receive the end or terminal .of any definite layer of said winding at a point ad acent to said layer, the position of the small opening designating that layer to which the end or terminal received thereby is connected to.
6. An electromagnet comprising a core, several windings each comprising a plurality of layers about said core, a spool head secured to each end of said core, and orifices extending through said spool heads, said orifices being adapted to receivean end or terminal of any layerof said windings at a point adjacent to any of said layers, the outer aperture of said orifices being so positioned as to indicate th layer to which the end or terminal received thereby is con nected to.
7. A spool for electromagnets having a winding andspool heads inclosing the endsv thereof, one of said spool heads having a slotted. aperture adapted to receivethe end or "terminal of any diameter? of windings,
substantially within the limits of th' apertured spool head.
