Application and December 17, mi. semi no. 523,153.
To all/whom it may concern.
\ Be it known that I, AnonrH R. Swonona, a citizen of the United States, 'residing lat Newark, in the county of Essex, State of l New Jersey, haveinvented certain new and useful Improvements .in Electromagnets, of which the following is a full, clear, concise,
and exact description.
This invention relates in general to elec- 10 tromagnets, and more specifically to a spool head construction particularly adaptable for electromagnets having laminated cores whichv are rectangular in cross-section. For electromagnets employing ylaminated cores, l it is often desirable that cores be so dimensioned that both ends are of a different crow-section than the central portion.y of the core and difficulty has been experienced in such cases in providingl suita le spool N heads which could be placed over the core end readily. 4
An objectA of the present invention is to4 rovide a spool head construction which can quickly and easilyinstalled or assemb ar or flat type` cores, and moreover, one which will be low in first cost and which will prove satisfactory in operation.
To accomplish this object, there is provided a spool head construction of two or I more parts, which may be quickly assembled on a rectangular typecore and locked in po- Sition.
The spool head is provided with a section lof insulating material securely clam ed bell vtween two metal. side plates and aving openings therein to permit terminal wires passing through the spool head. Referring to the drawing: Fig. 1 is a perspective view of an electro etiel structure employing 'spool heads em ying the invention;
Fig. 2 1s a view of the parts m the spool headof Fig. 1;
.Figs 3 .is a view showing the necessary el parts to rovide a modified structure ofthe typediscosedinFigA; v 1. l dig. 5 is a view of another modification;
*mh df Ispoo ea o Thereisdi skins up 6 shows one of the two parts ofthe lig. 5.`
osed an electromagnet in which the core is com of a number of laminations 7, 7 and a `flat member 8, which is preferably punched out of magnetic ma* Il tenal, such, for example, as siliconv steel.
Y4, a U-sha lare .no l fibre, are pl i rigidlyltogether and 'mii The end 9 is enlarged as shown to provide suitable pole area, and the end 10 is also enlarged to provide suitable mounting means for the device. T'he spool head con-l sists of interchangeable members 11 and 12, which are assembled upon the core in op site directions and are then securely loc ed in lace by bending over the tabs 13, 13. ese `members are preferably punched from sheet metal stock, and when secured together by means ofthe ta-bs 13, provide a ri id spool head, which also serves to hold the aminations 7 securely in place. Before placing the spool heads in position, an insulating member 14 is positioned upon the core, this member having its central rtion cut away to permit aembling. the spool heads and insulatin members 14 in position, the core is rovid with a layer of paper 15 for insulating portions, and then yis provided with a suitable winding 16. The members 11 and 12 have extensions or legs and the distance between legs is led made sufficient to permit the members to be slipped in place 'over the core laminations. In the modification shown in Figs. 3 and pcd member 17 of insulating material, suc as fibre, is locked in position' between U-shaped members `18 and 19. Pelforations 20,20' are rovridedf in the insulating member 17 an suitable openings 21 rov'ided in the members 18, 19 so that the eadin in wires of the winding may be ledthrong the spool heads and insulatedv from each other. n the modification shown in Figs. 5 and 6, a pair of U-sha members 22, of` -insulatin 1 material su as phein opposite directions upon a `cores and e elets 23, 23 passed through suitable pe orations 24, 24, serve to hold -the two members of the spoolhead at the` same time proe leadingvide means for the entrance of th in wires.
What is claimed iszsV `1. In an electromagne a core rectangular in 'cross-section, a Aspool 1 ead therefor comprising two members placed on the comin opposite directions,vand means for fixedly secuni said members together inoverlap' 105. ping re ation.
. 2. In an electromagnet,a laminated core a shoulder portion atene' end, a ead comprising a pair of` U-dllpedj members placedon said core Imo perpendicular mf to the plane of the laminations and sdja.- tions extending in opposite directions, and cent the shoulder portion, the legs of seid a plural-ity o e elets to secure said members l U-shaped members extending in opposite diin position an to permit passing of terrections, and means for securing said legs minnl wires therethrou h.
5 together in overlapping relation. In witness whereof. hereunto subscribe 3. A spool head comprising a pair of my name this 12th day of December A. D.,
homologous members of insulatdn mat'eria'l 1921. positioned adjacent each other wit leg por- ADOLPH R. SWOBODA.
