To all whom it may cc-azc Be it known that i, F

of Pittsbnrin the county c invented licsticn.

memo-electric U the. Winding as to I with ice vcntilz-ition of the structure.

in the construction of leininsted cove ii'iemhei's for dymnno-electric machines, suitable Ventilating plates have usually been inserted intervals between laminae. These plates l'orn spaces or openings through which the six can readily ciiculste. which the winding is located are often nearly closed and located near the suri's'ee formed "oyt-he edges of the laminae sotliat the portions of the lznninze wh cent to the small openings in slots are easily bent out of shape. T his particle lzuly true of such ls ininsa as are adjacent to the ventilating spaces.

in order to niske the. with out interfering with the core ventilation, provide of suitsble 1n steriel, the open ings in which. COII'QSPOllil in size and shape to use coil-section and thicknesses of c l comniiensurete with the WldhlS of J- vezitilctiiig Before the or "s, whih ordinarily inserted in the slots, are Flsced in position, the sfcrc-- core structure 1 of s. dynsmo-eicct'ic niachine is provided with ally closecl slots 2 which. at winding 3 located. Ventilct; ing oistes 4 are introduced at frequent intervals between leniinm to form series of air The slots are ccljw slots continuous 'weils o1 the slol in a, dynamo electric machine, the cont nineties with e laminated core structure Fig. 2 is a. I lan View, of c porf in each *sntilsting specs and encircling the core 2 which may pie "cbly, out not necessarily, he constructs n-insgnctizahle, meteriel, such as osses and which make the core slots continuous support the adjacent corners '03 the laminae Without materially interi'ering 1th the ventilation of the core.

.fiithougli 1 have shown s. portion c, sta tionm'y armature coie having substantially cylindrical and part e ll y' closed core slots the spacing mem'oei's of 111V invention are not restricted to so. lL sppli ion sml may be appnecl to cit i r she stationary or the rotating members of; various types of dynamo-slew tiic machines, the spacing members themselv s icing inside to conform in size and sh s nc to the coil-sections of the winding with which they used.

1 claim as I 'cntion:

.1. in a (c slim-electric machine, the com bination with stitionei'y frame, of s nmghie core. comprising groups of magnetizshle separated by ventilating spaces and having s plurality of slots, of spacing rings which fit into said ventilating spaces and. .eiicircle'seid slots.

In c dynamo-electric machine, the com bin ion with e Incgnetizehle core structure having ventilating spaces and. ccre slots substantially perpendicular to each other, of spacing Tings 'e'hich. ,enoiiole the slots and lit into I. venti s eces. v

is machine, the comlimited core structure in ii perpendicular to the ninze, of ventilating pistes is between said lamina,

havingsl ole.-w of' la located at mte and SP ting c ntnn onn lg slots for the reception of coils, of sewing members which are located at interels between the lsniinee and encircle the slots.

5. in e dyncmwclectric machine, the com lainzition with s laminated core structure haw- "ing members which are located in are spacing rings 6 mg slc-ts for the receptioncf coils, and venti in the ventilating 3. TINGLEY.
