FIREPROOF FLOORING.
SPECIFICATION forming part of Letters Patent N o. 775,516, dated November 22, 1904. Application led February 20, 1904l Serial No. 194,468. (No model.)
To all whom it may concern.-
Be it known that I, DUNCAN W. BOYD, a citizen of the United States of America, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvements in Fireproof Flooring, of which the following is a specification.
My invention relates to certain new and useful improvements in fireproof flooring; and its object is to produce a device of this class which shall have certain advantages, which will appear more fully and at large in the course of this specification.
To this end my invention consists in certain novel features of construction, which are clearly illustrated in the accompanying drawings and described in this specification.
In the aforesaid drawings, Figure lis a sectional perspective through my improved floor, the line of the section being indicated by the line l 1 in Fig. 2; and Fig. 2 is asectional perspective of the same oor, the line of the section being' indicated by the line 2 2 in Fig. l.
In the drawings, A A indicate the steel beams upon which the floor is built. A false iioor is ordinarily built below the level of the steel beams to give a surface upon which the floor material may be laid. -A series of tiles B C are then laid upon this false floor, the same being laid in alternate parallel rows. Each tile B, it will be seen, is hollow and provided with suitable transverse partitions to give it the necessary strength, and each has rectangular upper and lower surfaces and is trapezoidal in cross-section. The tiles B are laid with their larger end at the top, as indicated. The tiles C are of much less height than the tiles B, but, like the tiles B, are.
trapezoidal in cross-section, these tiles, however, being laid with their smaller surfaces at the top. Each tile C has iny the preferred form of construction a suitable anchor c, eX-
Vtending upward. After these tiles are laid in place the spaces between the upper parts of the tiles B are entirely filled with concrete or the like, and preferably with armored concrete-vl. e., concrete in which is embedded a metallic strengthening device, supporting and strengthening the concrete itself. In the form herein illustrated the device consists of tierods, Which are indicated by d, the concrete being indicated by D. After the concrete has readily apparent.
set the false work below the Hoor can be removed and the floor is ready for use.
The advantages of this structure will be In the first place the entire lower surface of the oor is composed of hollow tiling, which is the best possible fireproof material and which is also practically sound-proof. The floor is also exceedingly strong. The armored concrete itself being anchored by steel tie-rods possesses very great strength and can for all practical purposes be considered immovable. Each tile B bears to the two adjacent concrete sections D the relation of a keystone to an arch, and consequently is firmly held in position. The tiles C of course never receive any strain and may be held by the section of the concrete orby the upwardly-projecting anchors.
I realize that considerable variation is possible in the details of this construction without departing from the spirit of the invention, and I therefore do not intend to limit myself to the specific forni herein shown and described.
I claim as new and desire to secure by Letters Patent- 1. In adevice of the class described, the combination with suitable tiles, trapezoidal in cross-section and having theirlargerportion l at the top, of a plurality of sections of armored concrete in the spaces between the tiles, and a pluralityof smaller hollow tiles below the concrete and having their lower faces level with the bottoms of said first-named tiles.
2. In a device of the class described, the combination with suitable tiles, trapezoidal in cross-section, and having theirl larger portion at the top, of a plurality of sections of armored concrete in the spaces between the tiles,
la plurality of smaller hollow tiles below the concrete extending to the bottoms of said firstnamed tiles, and suitable anchors securing said smaller tiles to the concrete sections.
In witness whereof I have signed the above application for Letters Patent, at Chicago, in the county of Cook and State of Illinois, this 16th day of February, A. D. 1904.
DUNCAN W. BOYD.
