2 claims. (C1. 72;-118) f This invention relates to Yimprovements in sus` usual plaster layer is applied to the lower or lunder surface of the laths.

The present invention aims particularly at a construction for suspending the horizontal ceiling channel iron members'from the iloor beams and one of the objects is to provide members for.'

anchoragein the beams having integral malleable portions to be readily bent down and tied or secured about thechannel irons which are to be suspended. "I g` v A; further objectofrthefi-nvention is to provide suspended ceiling'l hangers which may be secured to the form boards and then cast directly in lower portions of the floor beams in a manner so that portions will be firmly embedded in the cast beams, while other portions may be bent Aentirely free of the beams for suspension purposes.

A further object of the invention is to provide suspended ceiling hangers which are easily installed and which maybe secured to'ceiling elements very readily and withv a minimum of effort, which are relatively simple and inexpensive, which are strong and durable, and which are well adapted for the purposes described.

With the above and other objects in View the invention consists of the improved suspended ceiling hanger, and its parts and combinations as set forth in the claims, and all equivalents thereof.

In the accompanying drawing in which the same reference characters indicate the same parts in all of the views:

Fig. 1 is a sectional View floor and floor beams showing-the installation of the improved ceiling hangers in the cast beams and the manner in which a ceiling is suspended thereby; v

Fig. 2 is a sectional View of the same taken on line 2 2 of Fig. 1;`

Fig. 3 is an enlarged side View of an improved suspended ceiling hanger in the arrangement in 55 which it is securedto a form and cast in a beam,

through a concrete part being broken away and in section to show details of construction; r

Fig. 4 is an inverted plan-.view of the suspended ceiling hanger; Figi 5 is a sectional View taken on line 5 5 of Fig. 3 andv on a larger scale; and f Fig. 6 is an enlarged fragmentary side View of oneend portion of the device with the frame. strip 'being shown in section. Y

' Referring now more particularly to the drawing it will appear that the ceiling hanger comprises an elongated' frame strip 8, preferably of semi-circular form in cross-section and having its lower edge formed with a longitudinally extending groove or recess 9. Said frame strip 8 '/@f is preferably formed of wood, but it is contemplated that the same may be formed to advantage ofk sheet metal, fiber or' paper board, or of composition. ,Also, said strip may be of any suitable length, dependent upon the particular buildingconditions. Adjacent each end-portion of the strip 8 there is formed therethroughat. right angles to the recess 9 and opening into the same, a bore or aperture 10,'said bores or aper-v tures 10 at opposite ends of the strip being later. 89;; ally off-set from one another, as best shown in Figs. 4 and 5.

The frame strip 8 serves as a housing and support fora pair of anchoring and suspending elements. Each of said elements is formed of bendable wire bent rto form a looped anchoring portion 11. The looped portion of an element is disposed in upright position adjacent lthe upper end portion of the strip 8 alined with an aperture 10 and with its plane at right angles to the 9g, vertical longitudinal plane of the strip. Two thicknesses of wire are depended from the looped portion 11 through the aperture 10 and then at vright angles flatly within rthe recess 9 of the strip and longitudinally of the same. Said thicknesses 95 of each element within the recess 9 form suspending ties and are designated by the numerals 12. It will therefore be apparent that each suspended ceiling hanger comprises a frame strip and a pair of anchoring and suspending elements. Said anchoring and suspending members are so disposed that each end portion of the strip has an anchoring loop of one of the elements pro jecting therefrom, and the double ply suspending ties of both elements extend adjacent each other longitudinally in opposite directions with- .in the recess of the strip.

by Figs. 1 and 2 wherein a cast concrete floor uit is designated by the numeral 13 and the concrete, depending floor beams by the numerals 14. During construction work, form boards to provide molds are suitably arranged to have concrete poured thereinto. The bottom form boards for the beams have nailed to their inner faces at suitable intervals, the frame strips 8. After the concrete for the iioor and beams has been poured and becomes set, the form boards are removed, and the frame strips and elements embodied therein are left embedded or cast in the lower portions of the beams 14, immediately adjacent the lower faces of the same, as shown. Staples 15 which are used to hold the tie portions 12 iiatly within the recesses 9 are removed and then the pair of ties 12 of each element are bent downwardly vertically away from the beam, each pair of ties being bent with respect to its anchoring loop 11 at about the points indicated at 16. The ties 12 as thus depended serve'to suspend channel iron ceiling members 1'7 which are extended transversely of the beams 14, and. the lower free ends of each pair of tie portions 12 are bent about a portion of a member 17 and are secured as shown. Any number of ceiling members 17 are suspended at spaced intervals as described, and below the members 17 are channel iron members 18 extended transversely to the members 17 and tied thereto by wrapping wires 19. Laths or a plaster base 20 are suitably anchored to the undersurfaces of the ceiling members 18 and then plaster 21 and other iinishing material is lapplied to the laths to form the finished ceiling.

It will therefore be seen that by means of the invention very simple and efficient means are provided for suspending a ceiling from the cast floorbeams in concrete construction Work. The ceiling hangers provide a permanent anchored connection between the beams and the ceiling elements and are easily and conveniently cast into the beams without any additional work. When required, the tie portions 12 are readily bent into position to be secured about the channel iron members. The arrangement is also such that any desired distance may be left between the ceiling and'iloor. l

While the improved ceiling hanger has'been described particularly in connection with cast Hoor beams, it is obvious that it is also adaptable to beam and slab, concrete joist and tile, and other constructional arrangements.

The improved suspended ceiling hanger is also of simple and novel construction, and is well adapted for the purposes described.

What I claim as my invention is:

1. In combination, a building element having an outer surface, and a pair of combination anchoring and spacing members, each'of said members having an enlarged vanchoring end portion and an integral elongated rod portion with the rod portion being bendable with respect to the anchoring portion, the anchoring Aportions of said members being spacedly embedded in said building element with the rod portions of the two members extending flatly adjacent the outer surface of the building element in overlapping relation, said rod portions being bendable free of the building element surface for variable spacing connection with separated portions of a second buildsurface of the floor. and the anchoring end por-Y tions embedded in the oor, the ties being in a depending vertical position and having their end portions secured to elements of said ceiling, the ceiling being otherwise entirely free of and spaced from said floor., A
