COHESIVE CEILING-FLOOR.

SPECIFICATION forming part of Letters Patent No. 464,563, dated December 8, 1891., Application filed March 11, 1891. Serial No. 384,567, (No model.)

the finished. structure, which provides spaces To aZZ whom it may concern.-

Be it known that I, RAFAEL GUASTAVINO, a. citizen of the United States, and a resident of New York, in the county of New Yorkand State of New York, have invented certain new and useful Improvements in Cohesive (Jeilingl loors, of which the following is a specification.

My invention has reference to the construction of buildings, particularly fire-proof buildings, and the improvements which I seek to protect in this instance relate to the floors and ceilings of such buildings.

The invention is applicable to buildings of all descriptions, such as dwellings, factories, school-houses, warehouses, the.

The object of my invention is to devise a cohesive ceiling floor which shall possess great strength conjointly with lightness and which shall also be absolutely fire-proof and indestructible when subjected to the incidents of'a [i re, and the peculiar construction of which will give to the finished structure the quality of self-deafening, whereby noises originating in any one story of a building in which my invention is embodied are prevent 'ed from being communicated to the stories sustains and gives strength to the other. In

above or below.

In fire-proofing it is desirable to have the structure of as little weight as possible; but this condition must not be carried to the extentot' sacrificingstrength and stability. By my construction, in which Ientirely dispense with the use of concrete or large bodies of cement and the like, I attain the condition of maximum strength with minimum weight, no similar fire-proof structure of which I have knowledge being of solittle weight with thesame degree of strength, the structure being also absolutely indestructible when subjectedto a fire and its incidents; and in my construction I so combine the iron and clay together that the former will be entirely enveloped and protected by the latter, so that none of the iron will be exposed to. view or to any unfavorable influences in any part of the structure, this being an important condition of my invention.

The floor and ceiling form one completehomog'eneous organization, in which each part between the floor and ceiling, both floor and ceiling are exteriorly fiat, intermediate arches of tiles working to sustain the weight of the floor. Said arches are maintained in place by their pressure being taken up by iron tierods extending between and fixed to iron beams of small section, on which the arches are supported, said tie-rods serving, also, to

support the tiles forming the ceiling element of the organization. As before stated, this peculiar organization imparts to the structure the quality of deafening sounds, which explains the term self-deafening made use of herein by me. p

The features of novelty for which I desire protection by Letters Patent are set out in the claims at the end hereof.

In the accompanying drawings, forming part of this specification and wherein like features are indicated by like letters of reference in the several views, Figure l at its .left hand shows a plan view of a structure embodying my invention'and at the right hand a plan, partly in section, of the iron.- work employed therein. Fig. 2 isa sectional elevation on the line 2 2 of Fig. 1. Fig. 3 is a central sectional elevation on the line 3 3 of Fig. l midway-between'two of the main supportingbeams. Fig. 4: is a view similar to the left-hand part of Fig. :2, showing some additions to the construction illustrated in the latter view; and Fig. 5 is a detail section along the crown of the arch, embodyingthe features of Fig. 4:. j

Referring to the drawings, a a indicate iron beams of small section. (Shown hereinthe form of rolled Zi-beams.) generally extend between the side wallsor end walls of the building. Where the. dis- These beams will tances between such walls are considerable,

the beams a may have intermediate supports between such walls in the form of ironposts or shafts constructed. in a fire prooff manner. b b are iron tie-rodsqlikewise of small section,

resting on the bottom flanges-of, the vertical E-beams c and bolted to bentplates or angle irons c, which in turn are bolted to the vertical I-beams a. The tie-reds I) extend histween beams and are inckosed in boxes or jackets f, of clay material, preferably made in short sections for convenience of manufacture andhandling. These boxes or jackets cover thertie-rods substantially from end to end, as shown, and when they are placed over the tie-rodsthe' intervening. space is filled with cement b in order to permanently secure the tie-rods and boxes or jackets together in their proper relative positions. The outer configuration of the cross-section of boxes or jackets f is substantially that of a triangle with its horizontal base depending beneath the bottom flanges of beam a. The inner surfaces of said box or jacket may be made to conform as nearly as practicable to the configuration of the tie-rod b. The boxes or jackets f when in position extend down below the under surface of the vertical beams 11, as-shown, so that the tiles of the ceiling 9 between the tie-rods b can be laid across, under, or beneath said beams a, thus completely concealing all iron by the clay, the exposed surface of the completed ceiling being flush with the lower surface of said clay boxes or jackets f, which cover the tie-rods, as seen in Fig. 3, for example.

The letters (Z (1 indicate arches made of tiles, preferably two courses, laid in cement and breaking joints, as shown. These arches, there beinga series of them, are built between and rest on the beams a, and, as indicated in Fig. 3, the tie-rods b are placed centrally beneath the arches (I, so as to counteract as nearly as may be the outward thrust of the arches. Ribs It, made of tiles laid in cement, are built, on top of the arches (l to fill outthe spaces between said arches and the contiguous parts of the beams (t. The arches d, as well as the ribs it, are carried to the same elevation as the tops of the beams a, in orderthat the first course of the floor-tilesi may rest directly upon the. top flanges of the beams a, the tops of ribs 71, and the centers of the arches (I. The tie-rods b, which tie the beams it together, serve, as stated, to make up the thrust exerted upon'the beams by the arches (Z, and to further assist in this direction the arches springing from one side of a beam a should be placed as nearly as" practi-.

cable in line with such arches as spring from the opposite side thereof, this arrangement permitting those arches springing from one side of the beam to counteract the lateral thrust exerted upon said beam by'thc arches springing from the opposite side of said beam.

The ceiling g is shown composed of two courses of tiles laid in cement and breaking joints. These tiles are joined together in panels, which extend between the flanges of the beams a and the sides of the boxes or ackelsf, the sloping sides of said boxes or seen that the under surface of the boxes or jackets j", by the construction described, are in the same horizontal plane as the exposed surface of the fin shing course of tiles of the oeili ng g, thus producing a fiat ceiling in which none of the iron on the structure is exposed and which can be lreadily'decorated or otherwise finished.

In the construction of Figs. 4 and 5 the arches (Z have abutments made of terra-cotta shoes (2, which have sloping outer sides corresponding as nearly as may be to the inclinations of the ends of those tiles of the arches which are made to rest upon such shoes. The shoes 6 receive immediate support from the lower flanges of beams a and are made of such configuration as to adapt them to [it closely over said flanges, and thus transfer the thrust brought to bear upon them to as large a surface of the beams as possible. The clay boxes or jackets f, inclosing the tie-rods b and which extend between beams a a, may be arranged to abut against the shoes e, covering the flanges of said beams when the shoes are made use of, and in such case the ends of said boxes or jackets may be made sloping to conform to the slope of the outer surface of the shoes e. The tile panels. of the ceiling g, where they come in contact with the shoes e, will also be made with sloping edges to increase the support for the ceiling.

The structure will be cheaper when the shoes 6 are omitted therefrom, and they are not at all indispensable. \Vhether omitted or not the construction serves to completely inclose' all the iron employed, so that the clay alone will be exposed to view, the iron being so enveloped by the clay that it will not be subj eeted to any unfavorable influences, such as moisture, flame, the.

The clay elements of my cohesive ceilingfloor are joined together and as far as practicable to the iron of the structure by cement,

thus uniting all of the material of the structure into a homogeneous mass or body, which wilLbe tlre-proof and ofgreat strength, though comparatively of little weight. The weight of the loads resting on the floor of the structure will be transferred to the beams a through arches (Z, which are well adapted for supporting heavy loads, while the weight of the celling is taken up and transferredto the beams and on the ceiling side with concealed spaces under the Iloor and above the ceiling, which construction acts to effectually prevent sounds in one room from being heard in the rooms below or above. As the ceiling and floor-are ICC practically finished in the construction, it is plain that my system has the merit, also, of much economy.

In Figs. 2 andii I have represented aseries 5 of wooden sleepers 7e arranged at the top of the structure, running parallel with the beams a and about two feet apart. These sleepers, which may have sloping sides, rest on the top flanges of the beams a and (between beams) 10 on the ribs h and arches d, as shown. When the sleepers are made use of, the tiles i of the floor are laid between the same close to their sides, as indicated in Fig. 3, and said sleepers extend about one inch above the upper layer of the floor-tiling.

The sleepers k are made. use of when it is desired to lay a wooden floor over the tile floor, and in doing this I place a layer of mineral wool l, of about one inch thickness, on top 2': of the upper layer of'the floor-tiling, and on top of this mineral wool the wooden floor m, about one inch thick, is laid and secured to the sleepers k by nailing or otherwise. This construction, with the mineral wool between the upper layer of tiling and the wooden floor, further serves to .deadcn sound, and thus has a tendency to increase the eli'ectiveness of the structure in that respect.

Having thus described my invention, what 3': I claim as new, and desire to secure by Let- .ent and crossing over the upper flanges of ,said beams, and a thin independent ceiling, also built of flat tiles laid in cement and cross ing under the lower flanges of said beams, 40 thus providing spaces between beams under the floor, and over the ceiling, substantially as set forth.
