. To @ZZ whom, ibm/ty carl/cern# Be itknown that JAMES H. DoUsM-AN, a citizen of the United States, residing at Kan? sas City, in the county o'l Jackson and State ol Missourh have inventedcertain new and useiiul liiiprovemcnts in Hangers, of which the following is aspecification. My invention vrelates to hangers for supporting false work for cement flooring, oeil ing, and other Suspended work; and my ob# ject is to produce a cheap hanger of this chan` acter which performs its work efficiently and reliably. x

A further object is to produce a hanger of this character of such-construction that its more expensive portion can be easily dis-` lodged, after the cement or 'concrete flooring is fset fonfuture use. i

. Toy-these ends the invention consists in cer- "tainnovel 'and peculiar features of construetion and organization, as hereinafter described and claimed, and in orderthat it may be'lfully understood reference is to be had to the accompanying drawings, in which- Figure 1 is a vertical cross-section `taken on the line l I of Fig. 2. Fig. 2 is a horizontal section taken on the line '111101 Fig. 1 with the cement'ilooring omitted. Fig. 3 is a detail perspective view Vof a modified construction oi' a hanger with its parts in operative relation. Fig-4 isa plan. View of the saine with the parts in the position they are caused to-assume lorthe purpose of dislodging or ref moving the rod, members,y said construction being modified in a respect hereinatter referred to.

ln the said drawings, 1 indicates one of the lciistomary Fbeams or its equivalent used in the construction of iloors and ceilings.

2 indicates headed rods arranged vertically at opposite sides of the base-fianges'ol the fil-beam with their non-headed ends projecting above said basedlanges, said nonheaded ends bein provided with threads 3 in Fig. 1 and wit projecting lugs 4 in Figs. 3 and 4.

' 5 indicates detachable heads for .the nonheaded ends ofthe rods, said heads in Figs'. 1 and 2 beingin the form of eccentricallypierced nuts, whilein Fig. 3 they are in the form of eccentrically-pierced plates provided with 'one or more offsetting passages G,

through which lugs L1 may freely pass. y rlhe detachable headsin each case inward of' thev rods rest upon .the base-ilaiiges'of the *li*4 Specicaton ofiLettere Patent. `lipplieiiticn filed July 6, 1905.A Serial No.- 268,493.

one or more outwardly-- Patented May 15, 1906..,

said rodssaid overlying portions of said de jtachablejheads are beveled at their under sides at 7' tocorrespond with,"aiid .therefore i i rest squarely upon,'the upper inclined sides of said 'base-'llanges,` as yshown clearly in Fig. 1.

`Inthisconnc-iction it should be stated that while said detachable headsare' prelerably pierced eccentric/ally, so as to obtain alongei i .bearing on the Vflan es oiv the Fbeain, it is not vabsolutely essentiathat heads "of such con struction beeniployed, as an brdinary nut of sufiicient size maybe utilized for said head. 8 indicates cross-bars iitting upon rods 2 and supported upon the permanent heads..

thereof, and 9 indicates longitudinal planks or timbers resting' upon said Crosabars, it being.

understood iii this connection that. tlieie'wil'l be a series of hangers depending from each li-beam in order to `form a' proper supportfor thev longitudinallyfextending planks or timbers, and it will also be understood that said cross-bars and planks or timbers are preferably secured in position beforethe heads are secured uponthe upper ends ofthe rods to. support them in position, lthe workman.

reaching in from opposite sides ofthe plankling 9 to secure said 'detachable heads in operative position.- -After the planking is dthus suspended from the beanithe side planking 10 and uprights11are secured in place, the

lattery serving .to support the side'planliing 1() in place and also to support the plank ing 12,

which underliesand forms a base for thatportion ofv the cement flooring extending from beam to beam, it being understood, of course, that the opposite ends ofy the floorplanking 12 rest upon the uprights 11 oil contiguous beams. To this false work per se no claim islmade, -because it is of common and well-known type, and it is only claimed in combination with this character of hanger. After the falsework is secured -the cement or concrete is deposited -to aboutl the level indicated in Fig. 1, that portion occupying the space between side planking 10 and floorplanking 9 forming depending ribs 13 in line with and below each ll-beain, as usual, While the portion 14 formsv the major part of the ioor between the beams'. It is to be understood that the rods receive'a coating in any suitable manner of heavy hibricating-oil, so ,asV to prevent the Vcement adheringA to them so tightly as to prevent them turning.

'l in the usual manner.

then unserevv said rods until thetv are wholl)IVY Withdrawn from the detachable heads', which of course remain embedded 1n the cement orA concrete, the cross-bars S and flooring 9 be.- ing removed from position with the rods. The above remarks appb,7 to the construction shown in Figs. 1 and :2.

, With theeonstruetion shown in Fig. 4 the rods are turned until lugs' 4; register with pas- Sages 6 and are then withdrawn from the detachable heads, the false work being removed If it. is desired, Vith the type of hanger shown in Figs. 3 and 4, to permit of the removal of the side planlging, uprights, and flooring 12 before the rods are totally withdrawn, the upper sides of the detachable heads mayv be provided with the inclined recesses 15, as shown in Fig. Ji, sai d recesses curving concentrieally of the openings and inclining downward toward the passages 6, so that the rods may be turned and permit of the removal of said side planliing, uprightsand ooring l2 before the rods are totally withdrawn.

From the above description it will be .zipparent that I have produced apparatus of the character described possessing the desirable features enumerated and which obiY viousl)Y may be modified in minor particulars without departing from the principle of construction involved.

Having thus described the invention, what I elaim as new, and desire to secure by Letters Fatent,is-` I l In false work for.eoiiorete building construction, the combination with a beam forniing a part of the permanent structure and having lateraltlange's at its lower end, of plates or heads supported by and projecting slightly beyond said flanges and provided with openings'near their outer ends, and removable supporting-rods detaehablyxv engaged in said openings, support-ed by .said plates and depending therefrom on opposite sides of the beam, said rods being provided with fixed heads at their lower ends to support. staging between which and the beam concrete may be placed, and the plates or heads being ermaneirtl)v surrounded by and Kembedded in the concrete.

In testimon)vv whereof l aliix in v signature in the presence of two witnesses.
