' Application flied nay 2s, 1901. serial No. 61,497. (no man.)

To a/ZZ whom it may concern:

Be it known that 1, CHARLES F. HAeLIN, a citizen of the United States, residing at Minneapolis, in the county of Hennepin and State of Minnesota, have invented certain new and useful Improvements in Fireproof Flooring; and Ido hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

My present invention has for its especial object to improve the construction of flreproof floors wherein concrete is reinforced and supported by embeddedwires.

To the above ends the invention consists of the novel devices and combinations of devices hereinafter described, and dened in the claims.

The invention is illustrated in the accompa- Y nying drawings, wherein like characters indicate like parts throughout the several views.

Figure 1 is a View, partly in plan and partly in horizontal section, on the line x' x' of Fig. 2, some parts being broken away, showing the oor and Walls of a building, the same being connected and constructed in accordance with my invention. Fig. 2 is a vertical section on the line @c2 x2 of Fig. 1. Fig. 3 is a detail of one of the -socalled tighteninglinks. Fig. 4 is a view corresponding to Fig. 1, but illustrating a modified construction; and Fig. isavertical section on the line x5 :t5 of Fig. 4.

My present invention is directed more particularly to the means for securely connecting or anchoring the composition ioor to the walls of a building.

In the drawings the numeral 1 indicates the walls of the building, and the numeral 2l indicates the, concrete body of the floor'.

In the construction illustrated in Figs. 1 to 3, inclusive, lhorizontally-extended Z-shaped Hoor-beams 3 are partially embedded in the walls 1, with one iange of each beam projecting from the wallsand serving as ledges upon which rest the adjacent edges of the cement floor 2. The kbeams 3 on the opposite sides of the walls 1 extend in the same planes, and at intervals they are securely tied together by nutted tie-bolts 4, passed through the bodies thereof and through the Fireproof floors.

embraced wall. The projecting flanges of the said floor-beams 3 are provided at suitable intervals with headed studs or pins 5. The floor-wires 6 are stretched over the pins 5 in any one of several different ways-as, for instance,-by using a series of loops, as shown in Fig. 1, and then tightening the said loops by driving the tightening-links 7 thereon toward the said pins 5. This arrangement of the door-wires is not hereinl claimed, as the same is claimed broadly in my pending application, Serial No. 37,229, Iiled November 2l, 1900, aud allowed April 24, 1901, entitled The said wires 6 are of course embedded in the body of the concrete floor 2, and they are preferably stretched to lmore than their normal lengths, so as to resist the initial downward-springing tendency Vof the iioor.

In the construction illustrated in Figs. 4 and the floor-beams 8 are connected and clamped to the wall l by the nutted clamping-bolts 4 in the same manner as are the beams 3, previously described; but in this instance the said beams are aiorded by angleirons, the outwardlyprojecting flanges of which are perforated, as indicated at 9. The floor-wire 10 is threaded through the said perforations 9 in the manner illustrated in said Figs. 4 and 5.

The walls 1, it will of course be understood, may be either of brick, concrete, or any other ysuitable construction, and the floor-beams may be more or less embedded therein. The said door-beams may take other forms than those described, but should in all cases be iianged beams having anges which project so as to form shelves for the adjacent edges of the cement ioor and a convenient device to which4 the Hoor-wires may be anchored or secured.

In the illustration given a single section or span of the ioor is shown as extended from one wall to another. In practice very frequently intermediate floor-sectionswould be interposed between the walls.

With the above-described construction, it

y will be seen that the tension of the door-wires on the opposite sides of one of the walls pull against each other, through the tie-bolts 4, so that the floors of a series of rooms are rigidly tied together.

IOO

The above construction is extremely strong and it is quickly put together and, furthermore, is of comparatively small cost. It will of course be understood that many other modiiications (not above illustrated) may be made within the scope of my invention. It Would be Within the scope of my invention as deiined in the claims to turn the concrete body, designated as a H0013 into a vertical position, and thereby make the same serve as a wall.

Vhat I claim, and desire to secure by Letters Patent of the United States, is as follows:

l. The combination with a Walland the concrete body of a Hoor, of parallel an ged beams on the opposite sides of said Wall, bolts or rods passed through said Wall and through the bodies of said floor-beams, which floorbeams have laterally-projecting fianges, and floor-wires anchored to said projecting ian ges and embedded in the concrete loor-body,sub stantially as described.

2. The combination With a wall and the concrete body of a licor, of a flanged beam secured to said Wall, and floor-Wires bent upon themselves and threaded over and over through perforations in the iange of said beam, which Wires are embedded in the concrete body of the floor, substantially as described.

3. The combination With laterally-spaced walls and the concrete body of a floor extending between said walls, of anged beams secured to said Walls and provided with laterally-projecting flanges, and floor-Wires bent successively in one direction and then in the other and threaded over and over through perforations .in the projecting flanges of said two beams, which Wires are embedded in the said concrete floor-body, substantially as described.

In testimony whereof I affix my signature in presence of two Witnesses.

CHARLES F. HAGLIN.
