T all w hom 'it may concern.'

Be it lmown that I7 MARQUES IVIEPCKE,

a citizen of Brazil, and a resident of thel which act as means for spacing the ceiling elevating screw embodying certain features t from adjacent structures. i

A still further obv'ect is the method of setting up a support and then casting a ceiling 'on the support in such a manner that certain parts of the ceiling will be connected with the floor members of the building. l

In the accompanying drawings- Figure 1 is a longitudinal vertical section through part of a room disclosing a ceiling and supporting scaffolding embodying the invention.

Figure 2 is a sectional view through Figure 1 approximately on line 2- 2.

Figure 3 is a detail perspective view of an of the invention.

F igure 4 is a broken away top plan view4 of a ceiling showing part of the scaffolding and how the matter is applied thereto.

Figure 5 is a perspective view of a number of iioor joists and reinforcing elements connected therewith. n

Figure 6 is a fragmentary sectional view showing a cornice and part of the ceiling, the same embodying certain features of the invention.

Figure 7 is a view similar to Figure 2 but showing how ornamental center and side pieces may be connected with the ceiling.

Referring to the accompanying drawings by numeral, 1 indicates a floor of a. room and 2 one of the walls thereof while 3 indicates the joists of the floor above. In the present invention it isy aimed to place the ceilings in position for each room before the ooring 4 has been placed in position though after the joists 3 are properly arranged. In

carrying out this idea according to they present Yinvention a number of depending plates or strips 5 are secured to the respective joists 3 by nails or otherwise, so' that the apertures therein will be in the same hori- Zonta] plane. lires 6 are positioned to extend through the various plates 5 as shown in Figure 5 andthen' transverse wires 7 are laid' tliereover-for forming a rather 4open net work which is to act as metal reinforcementfor the ceiling. Preferably in providing this net work of wires the various plates 5 are threaded' over certainof the wires and then secured in place, 'after which some transverse and some longitudinal wires are positioned as shown in Figure 5 and se- `cured by any desired number of tie wires5. f

In the drawing a tie wire has been shown at each crossing of the `wires but this is ordinarily not necessary as an occasional tie wire will 'answer the purpose.

I-Iowevenbefore the'net work of wire has been placed in position as shown in Figure "5, a scaffolding is arranged on floor 1. as

shown in Figure 1. This scaffolding consists of any suitable number of supporting uprights 8 provided with bores 9 for receiving the ends of the respective lifting screws 10. Each of these screws is provided with a wing nut 11 whereby the screw may be moved upwardly or downwardly. Each of these screws is provided witha plate 12 on which a vchannel iron 13 is placed. On the various channel irons 13 transverse additional irons 14 are positioned, the channelv irons 14 being of sufficient number to provide a proper lfoundation for the various bars 15 which are preferably wood and square in cross section. The bars 15 as shownv in Figures 1 and 4 presentan even lfoundation onl which one or morel strips of' linoleum 16 are placed or some other suitable sheet material which will present a smooth upper surface and which will lie liatwise against the bars 15. After the linoleum 16 has been placed in position the wire net work as shown in Figure 5 is then provided as above described and when this has been properly provided, both the scaffolding and reinforcement are ready for the .pouring action. A suitable finishing coat of plaster Paris or other materiall is then poured onto the linoleum and allowed to spread out under the action of gravity. If desired, this spreading action may be assisted bv a trowel or other instrument. When this layer has been properly placed in position a backing `correspondingly positioned.

layer 18 is poured, said backing layer merging into the layer 17 and submerging the wire mesh reinforcement as indicated in Figure 1 though preferably not extending to the lower surface of the joists 3. In this way the layers 17 and 18 are supported by the wire mesh which in turn is supported by the strips or plates 5 connected to the joists 3. Aafter the layer 18 has been properly poured and distributed, if necessary the entire structure is left standing as shown in Figure 1 until these layers have properly set, after which, the scaffolding is removed including the layer of linoleum whereupon a smooth finished surface is presented.

ln case the room is very large a number of blocks or strips of linoleum is used and usually there is a slight flange or bead formed between these strips of 'linoleum which must be cut off by a trowel or other instrument after the linoleum has been re moved. The aggregate forming layer 18 may be made with a composition including hair of any desired kind or in fact may be made of any suitable composition or vmixture and When properly cast will present an extremely strong ceiling which will support the weight of workmen if necessary.

Sometimes it may be desirable to provide a cornice for a room and when this is the case a cornice fitting 19 is provided as shown in Figure 6 which is clamped to one of the posts 8 or to some other part of' the scaffolding by any suitable form of clamp 20. The

plates 5 adjacent the corners 9 are made longer to'substantially conform to the shape of the corners and the reinforcing wires are Also, if de sired, ornamentation may be made in the center of the room or a short distance from the side walls as indicated in Figure 7. In constructing the ceiling as shown in Figure 7 the ornamental member 21 is arranged in position and supported on the scaolding below the wire mesh before any of the layers of plaster material have been placed in position. The side ornament 22 is' also placed in position and supported by the scaffolding though preferably the linoleum 16 is cutaway for accommodating the ornamentation 21 as well as the ornamentation 22 and the ornaments are usually supported entirely or somewhat by the linoleum. The casting then is made in the manner above described and by reason of the adhesive qualities of the layer 17 it will readily ad here to the ornamental members 21,and 22 so as to thoroughly support the same and in turn be supported by the layer 18. l

After the two layers 17 and 18 have been deposited and allowed to set, either with or without the cornice 19 or the ornaments 21 and 22, the scaffolding is removed carefully and the linoleum 16 is finally removed carefully which may be readily done as it will usually peel ofi' when the layer 17 has set. rlllhis is possible because the linoleum is smooth on the upper surface and consequently the layer 17 will not readily adhere thereto.

This construction of ceiling is very strong and also provides an air space below the joists and above the ceiling. This air space is important for many reasons, as for instance, it consists in preventing the spread of fire and provides a dead air space which will make a sound-proof construction very desirable in apartment houses and elsewhere. 1n Figure 1 of the drawing only a small space `below the joists has been shown but it will be evident that this space may be large or small as desired.

' lVhat l claim is':-

ln a ceiling of the class described, a plurality of hangers each consisting of a strip of metal, means connecting said hangers to a support, a reticulate suspended from said hangers, said reticulate consisting of a plurality of wires each extending parallel to the other and through a series of said hangersl and a plurality of wires eX- tending across and secured to said'first mentioned wires, a plastic body embedding said reticulate, and an ornamental finish on the under surface of said plastic body.
