r This invention-relates, to a sectional core for formlng an orifice or passage'throughja concr'ete'floor during the processof molding 'thesam'e in situ'uponthe usual temporary form or false work. Andthe present} improvement has for its object: 7 V To provide a structural. formation and combination of parts in a sectional core of the tubular type, adaptedforv readya'pplica tion and substantial attachment to the surface of themold board npon which the floor is formed in situ, and at the location in which an orifice or passage is desired inthe floor, all as will hereinafter more fully appear.
In the accompanying drawing Y Fig.1 is a perspective View of the upper .member of thepresent tubular core struc-l ture, in a detached condition.
Fig. 2 is a similar view of the lower member of the tubular core in a like detached condition.
Fig. 3 is a detail top view of the upper core member;

v Fig. 5 is a detail section of the lower core member on line 55, Fig. 4.. V Fig; 6 is a detail section of a portion of concrete flooring havingthe present core in place, with the upper and lower core members shown inse etion online 5'5, Fig. 4;.
Fig. 7 is a detail section similar to Fig. 6,

' .Like reference numerals indicate like parts 1n the several views." 1 7 The present improvement is intended for use in connection'with that classof concrete floors 1 which are molded in place upon a 'horizontal'mold board or form 2 supported .in position by the usual temporary frame or false work, and has for its purpose to 'aiford a ready and substantial means for forming vertical'orifi'ces or passages throughthe con-' crete floor at points desired and during the molding of the floor. I
7 To such end the present inventioncomprises an upper tubular member 3, prefer-' ably of a cylindrical form as shown, and
havinga length somewhat greater than the thicknessof the concrete floor 1 with whichit is'associated. At its lower end the mem oer 3 is formed with a pluralit -of outstand ing lateral coupling ears or flanges; for in terloc king engagement the fixed: erjcmember of theappliance now to bejdescrib'ed. v
I The base or socket member above. referred 1 to is of a diskshapeand formed withajse- ,ries of nail holes ';6 by. which 7 it is firmly "nailed to the mold "orform2 at the desired locations. In the present improvement said socket'member'is formed witha raised central crownlor web' 7 provi'dedlwitha central orifice 8 adapted to receive and have'a hold;
jing engagement with the lower'endi of the tubular memberv 3f aforesaid and with .the 1 coupling lugs 4. of the upper member engaged beneath the margin of said orifice.
At intervals aroundthe margin of the orifice 8, and in the margin thereof, a plurality of notches 9 are formed, with'said notches having a complementary shape to that of the coupling lugs t ofthe upper tubular memher 3, to permit downward passage of the lugs through said notches in anassembly of the two members of the appliance.
Adjacent to the notches'9, the margin ofthe central orifice 8 is formed with a plu rality of inclined webs 10, underneath which the coupling ears 4 of the tubular member 3 ride to force said upperfmember downward against the upper surface of the form or mold board'2 to attain arig id andsubstantial attachment'of said uppermember in proper vertical position.
In the preferred construction shown, the outer'portion of the base or socket member is formed with a plurality of raised webs 11, alternating with'the nail holes '6 of the same, and witheach web 11 formedwith apertures 12, for the entry of unset concrete below the webs 11' to insure an effective attachment of said base or socketmember in place in'the finished concrete floor, 1. t
In practice, and during the concrete Lfloor 1, th e cavity of the upper likeloose material to prevententryof any of the concrete materialfrom which the floor is formed.
iHaving thus fully desc ribed my invention socket member having nail holes for fasten the formation of r 'tubularmeinber 3 will be filled with sand or ing the member place sp a s inoklhnarsl v said socket member having a central raised portion formed with a central orifice and floors, the combination of; a"' 31ate m'eta1 socket member hat ihgnail holes for faetening the member in place upon a mold board, said socket member having a central raised portion-formed; with a central orifice, and anuppejr tubnlar core member the lower end of which passes through the central orifice of said socket member and is provided with .qutsmndn ig flanges tor engagement beneath the margin of said orifice, the. portion of the socket member surrounding its central of March, 1926'.

raised and orific'ed webs; V c
3. In an orifice forming core for concrete floors, the combination of a plate metal socket member having nail: holes for "fastening the member in lace upon a, mold board, said socket member having a central raised portion farmed-with a central orifice and with notches and nclined surfaces in the niargiiiof said orifice, and an upper tubular core member the loWer-end of which passes throng'h th'e "c'eiitral "or'ifice er" the so ket member and is provided with outstanding flanges for 'n agementbeneath the inclined surfaces in t e margin, of the aforesaid central orifice, the portion of the socket member surrou'ndiilgits central raised portron be ng formed' wi'th a series of raised and orifice'd' Webs;.
