HANGER-SUPPORT FOR CONCRETE OEILINGS.

Specifieation'of Letters Patent.

Patented April 9, 1907.

' Application filed. September 19,1906. Serial No. 395.229.

To all whom it may concern:

Be it known that I, ARTHUR J. PERKINS, a citizen of the United States of America, and a resident of S ringfield, in the county of Hampden and tate of Massachusetts, have invented certain new and useful Improveowing is a full, clear, and exact description.

This invention resides in a hanger-support, preferably made as a casting, to be embedded 1n 0. vertical position in a concrete ceiling and consisting of a hollow body having at the lower portion thereof a vertical downwardlyleading opening with ledges at o posit-e sides of such opening, said opening aving a dimension in one direction greater than in the other, whereby a hanger-nut may be inserted in said opening and be positioned within the support to rest on said ledges.

The invention furthermore consists in subordinate features orformations and provisions for advantages hereinafter rendered apparent.

he improved hanger-support is illustrated inthe accompanying drawings, in

Figure l is a vertical sectional view through a concrete ceiling, showing a hangersupport embedded therein' and interlocked therewith, the said support having combined therewith a hanger for a pipe. Fig. 2 is a vertical section, on a larger scale, through the support and hanger as taken on the line 2 2, Fig.1. Fig. 3 is a similar sectional view, but as taken .on the plane at right angles thereto,

indicated by line 3 3, -Fig. 2. Figs. 4 and 5 are horizontal cross-sections taken onlines 4 4 and 5 5, Fig. 3-. Fig. 6 is an end view of the support as seen at the'bottom thereof.

Similar characters of reference indicate corresponding parts in all of the views.

I may be engaged with and suspemled from In the drawings, A represents the hangersupport, B Fig. 1 representing a concrete ceiling, in which the support is embedded, and C represents one form of a hanger which ing, the said opening, as clearly'seen in Fig. 6, avin g a dimension in pne direction greater.

than in the other.

The lowered chambered portion 0 of the cast-iron or otherwise constituted hangersup ort is shownas rectangular in form,

whi e between such rectangular portion and its upper end the casting is cross-sectionally circular, is downwardly tapered,- is made with sidewise extended webs or flanges f f, and has transversely-extended flanges g get its upper end, such formation and flanges roviding for an efiicient interlocking ofthe anger-support in the. concrete, preventing displacement in a downward direction or under any force tending to turn or twist it from its given set'position.

It will be observed that the flanges ff are substantially diametrically opposed and that the flanges g g are similarly related and that the two sets of flanges are, roughly speaking, arranged in quadrature. Moreover, the

flanges ff and g 9 both project beyond the the body, and the flanges f f are set free of the overhang of the flanges g g. From this arrangeinent flows a very important advantage as follows: As to downward strain, the hori zontal flanges g g bear upon underlying bodies of concrete, which are not broken up or (llvided by the vertical flanges f f, while, as to a rotative force, these latter flanges are resisted by portions of the concrete structure which are not subjected to the downward compression of the flanges g g. The result is a very strong embedding of the hanger-support in the surrounding material.

1* represents a nut, which in the. present instance isshowir as of a rectangular form having a distance from side to side greater than the width of the opening I), but not quite so great as the length of said opening, and the thickness of the nut is less than the width of said opening I), and it is to be understood that in the construction of a building having concrete ceilings the hanger-supports are embedded in suitable arrangement in the concrete ceiling, with their lower ends flush,

or substantially so, with the under surface of the co crete which makes the ceiling, and when .it is desired to mount a hanger the nut is inserted. cdgewise through the opening b within the chamber above the ledges d d and then turned flatwise to rest on the ledges, as represented in Figs. 3 and 4, whereupon the hanger, having a screw-threaded or bolt-like shank, may be inserted through the opening b and engaged with and screwed through the: threads of the nut more or less far, as de-' sired, for acquiring a reliable supporting of the hanger and the proper adjustment thereof.

It will be perceived that the walls of the rectangular portion of the hanger-body will engage with or be engaged by the nut, so that the latter will be prevented'from rotating while'the threaded shank of the hanger is screwing therethrough. It is to be noted that lower chambered portion 0 of the hanger is restricted in extent as-to both lateral dimensions. Preferably these two dimensions are substantially equal, so that the-chamber will be but little larger horizontally than an ordinary rectangular nut of the' 'proper size. This construction insures that not onl will the nut be locked againstirotation whilla liO or o ening b.

Tii

ate portion of its hei'ght an internal flange 1',

inclosing an opening permitting the free passage therethrough in an upward direction ofupward and. rotated to causel'itsthreads to engage with the tapped-portionigof the nut. It Wlll be recognized that i 'is important'to provide some such stop or abutment for the nut, else. the latter --wou ld have to be forced clear to the top of the interior'ofthe hanger before the threads of the bolt could secure a purchase. It will be obvious, however, that a flange is not necessary for the provision of such a seat, as, any suitable form of stop or constriction in the bore of the hanger a short distance above the opening I) would serve the urpose. hie utilityto become available in cases, for -instance,- where the ledges might become broken away to lose the nut-support or'in cases where" some special hangers having larger shanks might be'desi'rably used, and it is evident that by inserting a tap or thread cutting tool upwardl through the opening b a thread, as indicate at a: by dotted lines in Fig. 2, may be formed in the inner edge ofthe fla e j to receive screw engagement therewit of the threaded shank of the hanger of properly large'diameter.

or the purpose 111st mentioned it follows that the circular aperture through the flange would have to have a smaller diameter than the width of the opening I) in order that it 6 might fit closely the bolt which passes loosely ;slotted, opening and communicating with the bolt is being screwed therein, but the nutwill be prevented from sliding side'wise in either direction to a material extent. This is also insured by limiting the length of theslot f "longitudinally eadin This flange is a provision of possithrough the latteri If the flange serves merely as a seat for the. nut, it is'apparent that such relation between the diameter-of the flange-aperture and the width of the ter minal opening need not exist.

Hangers havin otherwise than hook for: mations at their ow'er portions' will be pro- .vided for the supporting of various objects from the ceiling.

Various changes may be made in the design andshape of the parts'without depart- 'ing from this invention or sacrificing 'any'pf the advantages thereof, and it"is manifest,v

. 1 a that the castings may beem loyed in ho 'h the interiorof the zontal positions in the side wa ls-ofbuildings',

as well as in ceilings.
