f In the-construction ofk a modern ltypre of f 5 building, particularly those'with concrete floors, alarge item of the cost of installing the piping is 'that ofpreparing suitable `pas` Y sages for the risers and' for the means of anchoringsuch risers at appropriatejpoints in 170 the building. It has been customary to place a'sleeve in position Apriorto the pouring of theconcrete floors and thus vrhave suchgsleeve.

. satisfactory anchor( The cost of this'work kmaterially adds `to the cost of the construc- 25 -tionof the building and is at bestbut a'makeshift.A Further, where .the 'anchor is buried in the floor it is practically impossible toremovev the pipe f for vrepairs or replacement.

- EPI-n my present invention I-have obviated v; 30ltheobjections of-prior construct-ions and have` v `devised anv improved'combination anchor and l l l'isle.evewhichv may be installed'in permanent positioni duringV the erection of the building and the pouring of Vtheconcretefloors there- *iin-and which may be used as a'straight sleeve or as jaV means for vanchoring a riser in positio'nfat any desired pointin'the building or '.both. In lcarrying'ol'lt my invention I provide ah centrally arranged cylindrical portion- Aprovided with ylaterally extending wings thereon 'and which may befirmly anchored 1 within the concrete formingthe floor of thel A building. This element is preferably located intermediate the upper andlower faces of the nfloor, and screwed into the top and into the bottom, should 'it be desirable, is a sec- Y* tion of pipe, thus forming a through passageV or sleeve in the floor. Secured to the lower end of the cylindrical element so as to -be re- 1f2.50 movable 'from the lower face of the floor is 4 ing of any rsuitable dimensionsl Thecylinthreaded end .of/a section of pipfel.- The an element the shape of collar, acts asa cover for the housing, withinwhigh lengths ofk pipe forming elements of thessystem ofpipe in the building, 'and such coupling 55 togetherv with the "cylindrical :portion an-k chored within the cement floor. acts as ananchor for thepipe forming part of the system of pipe. l/Vhere theV device is to beusedfin connection with furred or dropped ceilingslo Yin concrete floor construction, I preferably i' secure to they ceiling a short length of pipe yextending downward `through the .furredfor dropped ceiling. With my improved device, l am able to readily and easily remove the Q5 piping for repair or replacement. i Theobject of` my invention, therefore, `is ain; improved combination anchor `and pipe sleeve; .Y 1

In the accompanying-drawings- Fig.,1 designates a side'elevation of my' improved anchor and pipe sleeve shown inl Fig. 3 is a sectional botto-m plan onthe yF ig. 4 is aside elevation, partly insectionof amodification. v

lReferring to the drawings, 10 designates a cylindrical member having formed integral therewith and diametrically arranged with respect lto each otherV laterally extending lwings or plates 11, such wings or plates 11bedrical member 10 is counterboredat one end, asindicated 'at 12, such counterbored. porek tion being o flaf` suitable diameter andfdept-h `to receive a coupling lforming'part ofjaj piping s ystem. Also, the Vcylindrical member 10 is counterboredat vthe other end, such coun- .terbored portionl beingof suitableY depth and tapped, asjindicated aty 14, to receive the depth of thecounterbored portions is suchas 5 toleave an---intermediatelylocated wall 16 in .the cylindricalmember 1Q, which is drilled,

fat 17 toV receive as a loosesliding iit a pipe .-18 'formingpart of v the Vpiping 'system of the building, andthis' piping 1 8 is `threaded into igloo -thereofis drilled and tapped to receive the threaded Vend of cap screws 19, which cap screws are utilized to hold a. collar 20 in position on the lower'face of the cylindrical member 10. This collar 2O is drilled at 21 to i soV allow a pipe 22 to pass through as a loose sliding fit and which pipe 22 .screws into the lower end of the coupling'Y 13 and forms part Y of the piping system of the building. The

sleeve above described and as illustrated in `Figs. 1, 2 and 3, is adapted to be embedded in the concrete floor 23 duringthe pouring of such floor and in which event naturally the sections of pipes 18 and 22, as well as the coupling 13, are not present. In such event also it will be obvious that the section-of pipe 15 of suitable length, depending on the thicli- Y ness of the flooring 23, will be screwed into the threads 14; and l viind it preferable to have such section'of pipe 15 extend for 'a slight distance above the finished surac'eoi' the floor, as clearly shown in AFigs. 1 and 2. It is desirable to have, from a inished standpoint, the lower face of the collar 2O substantially flush with the lower facero't the floor V23 andin order that this may be done, I 'iind it preferable to, during the process of construction, substitute for the cap screws 19, other screws somewhat similar but of a lengthtopass through the usual mould board employed in casting the ioor 23. That is,

the mould board is put in position with'the holes registering with the holes in the collar 20 and the long cap screws pass through the holes in the mould board and through the holes in the collar 20 and then intothe tapped holes in the Vbody of the cylindrical member f i combinationof a cylindrical member, anchorf 10. It will obvious therefore that the mould board employed has secured thereto not only a collar 2O but also the cylindrical 'member 10 that carries the section of pipe 15 and that the mould board, being fixed in position as regards the floor, that the cylindrical member 10, togetherV with the attachments thereon, is also similarly iixed in position. After the floor 23 has been cast and has had time to set, the mould boards employed are naturally removed and tliereiore'the long cap screws employed are removedV and the cap screws 19 shown in Figs. 1, 2 and 3, are substituted therefor and the device is vnow in fixed position within the floor 23.

When used as a sleeve and not as an anchor, the .pipe 18 or 22, or a similar pipe'is passed through the openings'21 andf17 and the construction, therefore, is merelyV la sleeve.,

Should itbe desired, however, to utilize the construction as an anchor, the cap screws 19 are removed, the collar 20 also` removed and a coupling 13placed inthe counterbored portion 12, afterwhich'the collar 2() is replaced,

as are alsothe cap screws 19, and the device 18 and 22 are screwed into theupper and low- Vname to this specification.

cylindrical member 10shown in the drawings and expansion takes place, therefore, in such pipes upward and downward respectively from the cylindrical member 10., Y l

My improved device acts as a support for a vertical pipe, obviating the necessity of putting in a pipe hangerorsupport. Further, it maybe used in the horizontal position and acts'in this position as a support, and as an anchor. s Y ,Y y

In Fig. 4, there is shown afmodification of my device employed Vwhere a.; fur-red' or dropped ceilingis utilizedpsuch Vfurred for' dropped ceiling Vbeing indicated by the Vreteience numeral 24. The construction of this inodiiicationvis identical Ywiththat shown in; Figs. 1, 2 and 3, except that the lower, surface oi' the collar 20 is'threaded, as indicated at25, to receive the upperthreaded end of aA section of pipe 26 that is long enough to extend down- Yward and through for a'suitable distance be-f;

yondthe lower ceiling 24.
