sLPECIFICATION forming part of Letters Patent No. 741,289, dated October 13, 1903.

Application filed August 9,1902. Serial No. 119.082. (No model.) I

method of constructing floors, while it par-' ticularly relates to so-called fireproof flooring and to the construction thereof. Its object is to provide efiective, comparatively light weight, and economical flooring of asplastic composition which shall whenset pos-' phalt, of cement, or of substantially similar sess great vertical strength.

Referringto the accompanying drawings, wherein like reference-letters indicate the same or corresponding parts, Figures 1, 3, 4, 5, '6, 7,8, and 9 are in part sectional views and in part elevations, andFig. 2 is a broken plan view.

Heretofore in the construction of doors of cement, of asphalt, or of other composition a plank platform or centerfis erected or a swing suspended beneath the place to be filled in such' manner as to close the lower end of the opening between the floor-beams,

' thereof. Owing to the weight of floors so and upon it cement, asphalt, or other composition is deposited and tamped down until the space between the floorbeams is com pletely filled. When this filling has become set, the center isremoved. :Floors so con-' structed are objectionable, because of the excessive quantity of filling composition necessitated andthe consequent costand weight constructed it has been necessary tosecure the floor-beams one to another by tie-bolts or. brace-beams at frequentintervals to prevent them from spreading and to relieve the walls by said weight...

of the building from the pressure occasioned By employing the device and method of constru'ctionof my iuventiona large saving in materials, cost, and weight is effected I without impairing the vertical strength of the cement or other filling; To these ends my invention consists in the features of construction and. combination 'of the'I-beams A hereinafter more fully described, and pointed out in the claims hereto annexed. fReferring particularly to Figs. 1, 2, and 3:

of the drawings, A, A', and Marc I-beams,

A and support the members B in upiii'ght position, as shown in Figs. 1 and 3, and f lie substantially parallel to and separated I "a comparatively slight distance from each other, as shown in Fig. 2.

The filling D is thereafter deposited betweenand tamped about the members B in such manner as to firmly embed them therein. When thefill ing has become sufficiently set, the center may be removed. Where the distance so arating the I-beam A'from the'Ibeain A is considerable-say ten feet-the members B should possess suflicient strength to'sustaiu themselves and also to assist in sustaining the weight of the filling,- This may be offectedby forming said member of stitfer and stronger or of heavier material than where the distance separating said I-beams is, say, three or four feet or by suitably corrugating the tubular part b. Again, auxiliary supporting meansmay be employed-as, for exa-mple,-the bars E (see Figs. Sand 9 )-pref- .erably laid in adirection substantially at right-angles, to the longitudinal direction of the members B and supported at their extremities, respectively, by thelower flanges In Fig. 4 I have illustrated the member B in five different forms. In; the form. shown at the extreme left of said figure the memberb is elliptical in cross-section. "In the form shown next to the riglit of the one last referred to; the member I) is also elliptical in cross-section andprovided with peripheral tal, whereas in the form first referred to it is vertical. In the form shown in the center of the drawing the member bis substantially of two pieces of sheet metal or other suitable square in cross-section. In the form'shown immediately to the right of the one last referred' tobthe' member 11 is of diamond form in cross-section, and in the .form shown at the extreme right of the drawing the mem v pieces permitting the hollow members to be ber b' is spirally corrugated. 1

In Fig. 5 the member B is shown formed material secured to each other by screws, bolts, or other suitable securing means F.

In Fig. 6 the member B is also shown formed of two pieces of sheetmetal or other suitable material, which may or may not be secured the one to the other, as preferred.

In Fig. -7 the construction shown is substantially that illustratedin Fig. 5, the two however, being secured together by means of flanges G of any suitable si'ze, form, and

number on the one piece, which enter suitable apertures or slots in the other piece.

In Figs. 8 and 9 the member B is not provided with a web and foot, 'but rests upon the bars E, ashereinbefore described.

It is obvious that the space between the beams A, A, and A may be partially filled with cement, the member B be laid upon the top thereof, and thereafter the unoccupied space between the beams be filled to the desired level and tamped down into proper place, that the member B may be constructed in sections, and that the number, size,

and form of the various parts of my device may be greatly varied without departing from the principle of the invention.

In the forms of the member B, which have a web b and foot 11 I havedescribed them as being supported by the flanges of I-beams. It

will be understood ,thatthese members, of

whatsoever form they may be, may enter suit-.

able apertures inthe walls of a building or be otherwise suitably supported, while it will be further understood that, if desired, said fI-beams disposed transverse to said hollow members may be secured one to another, it being only essential that a space occur between them'. The flanged foot-pieces b serve -5o as supports for the hollow members B by rest-'- ing on the flanges of the'I-beams or in the. apertures in the walls of the buildings,;so that said members will stand properly inplace' when the concrete or cement is being filled in between them, said flanged footproperly separated from each other, so that the concrete can be properly tamped about and beneath them, and thus form a cement 6o ceiling to which plaster may readily be appliedwithout requiring special plaster holding or attachingmeans. Again, it will be understood' that the word cement. wherever, employed herein shall signify any suitable floor-filling composition, such as asphalt, concrete, cement, &c.

f Having thus descrlbed my invention, what I claim as new, and desire to secure by Letter Patent is- V r 1. In the fireproof construction 0t floors,

ceilings, &c.',- the combination with a cement ,or concrete filling, of a series of separated hollow members embedded in said filling and provided with flanged foot-pieces, as 12 and suitable supports transverse to saidhollow members on which said foot-pieces can rest while thecement or concrete is being filled in to form the body of the floor or ceiling. 2. In-the fireproof construction of floors, ceilings, &c., the combination with a cement or concrete filling, of a series of'separated' hollow membersembedded-in said filling and provided with fiangedfoot-pieces, as b and 8 5 members and against the flanges of which I- ,beams the said foot-pieces can rest while the cement or concrete is being filled in to form the body of the floor or ceiling.-
