HOLLOW TIL.

To all whom t may concern lle it known that'l., VILLIAM H. Bunn, a citizen of the lUnited States, and a resident of the city of St. vLouis and State of Mis.

souri, have invented a new and useful Improvement in Hollow Tiles, of which the followingfis a specification. 4

My invention relates to hollow tiling for use in floors, walls and other parts of structures, and consists in` anew and improved form of tile `unit adapted to be used with plastic material to' form an improvedstructure.

The objects of my invention are, to lighten the structure without sacrificing strength, to lessen the 'cost of construction by eliminating m-uch expensive false work or centering and by enabling thewcrk to be done by unskilled labor, and to make the structure damp and cold-proof.

My invention comprises a hollow tileunit formed in two sections so as to be completely linclosed on all sides, and provided with lat-4 eral flanges. Such aunit is practically impervious to moisture, and is an excellent non-conductor of heat, and may be used vfor floors, walls, ceilings, furring, ireproong and analogous uses in buildings, for paving, for cisterns, wells, bulkheads, chimneys and similar masonry structures. v

My invention further consists in the herein described novel arrangement of hollow tile units to form improved heat-insulating and moisture-proof building or masonry structures.

My invention also comprises otherV improvements as more fully hereinafter set forth in connection with the accompanying drawings, in which like numerals are used to designate like pants. throughout the several views,l and in'which- Figure 1 is'an isometric view of one form,v

my improved tile illustrated in Figs. 1 andI 2. Fig. tis a 4partialplan view. of a Hoor panel embodying' my improved tile units with reinforced concrete placed in thespaces between adjacent units; Fig. 5 is a section on line 5--5 of Fig. 4, and Figl isa section on the lined-Gef' Fig. 4;

upper section 11, a lower section 12, and a y stiffening member 15, heldtogether by thin'- webs at 16. The stili'ening member may be omitted, andis not necessary with small tiles. -Such shape lends itself ,readily to manufacture in a pug mill or tile forming machine of ordinarytype. `The webs are thin enough that the baked tile may be cracked in pieces, the piece l5 being discarded. The pieces 11 and 12, when arranged atj right angles to each other as shown in Figa@J and the part 11 brought down to embrace the part 12, form a hollow tile unit completely closed on all six sides. The sections 11 and 1Q are provided with lateral flanges 13 and 14C, adapted to form a flange extending substantially all the way around the lower edge of the assembled hollow tile unit as shown in Fig. 3. The form and arrangement of the tiles are such that in assembled relation the side walls of each tile making up a unit snugly embrace the web of the other tile of the same unit, thereby interlocking and securing each other in assembled position.

When the tiles. are arranged in rows on flat surface `adjacent one another withf y anges in juxtaposition, square spaces at the corners of the tiles between the flanges are left unfilled, and. small flat tiles 17 are placed therein in order to completely cover the surface on which the tiles rest. Plastic material may then be placed between the tiles, andsuch materia-l willneither penetrate to the interior of the tiles, as would be the case if the sidesvwereperforated, nor will l it pass through between the tiles onto the suplporting surface. Such tilesmay `be used 1n floor panels, for example, supported only on skeleton centering, and concreteor other plastic, or binding materialv placed in the spaces between the tiles over the flanges thereof, these vflanges and the small square tiles 17, serving to .supportthe plastic material until such time as it shall harden suflif Vciently togive it strength enough to carry the floor load, after which .time the centering may be removed. As the extremities of Athe-'side `walls ofeach tile snugly embrace thel web of the mating tile and are prevented `thereby from being thrust inward, the holv low units may be safely exposed to heavy pressure on their exterior, suoli as is incidental to the placing and tamping of plastic concrete, for example, without danger of cracking ott' their side walls. Much less lumber'tor centering need be used with my improved tile units than with tiles not provided with means for supporting the plastic material, vbut where the centering itself is relied ou for this purpose.

Reinforcing rods may be inserted in the spaces between the units before the concrete is placed, and arranged to extend crosswise in both direct-ions through the panel from the margins thereof, thus providing a twoway reinforcement. Such an arrangement is shown in Figs. 4, 5 and 6, in which the hollow tiles formed by assembling the parts l1 and 12 to embrace each other are arranged with the flanges 13 in juxtaposition throughout the panel in one direction and the anges 14 in juxtaposition in a direction at right angles thereto. Reinforcing rods 18 and 19 are positioned near the bottoms of the spaces or channels thus formed between the tiles, and above the lateral flanges thereof, and these spaces are then tilled with concrete. These o erations can all be per- Itormed by unskilled labor as there is no necessity for pointing the tile with mortar or cement as is necessary with the ordinary tile having openings therethrough, for there being no openings in the side walls of thev tiles, the concrete can be poured into the intervening spaces without danger of filling up the hollow spaces within the tiles. The lateral flanges 13 and 14; and lling tiles 17 provide an unbroken surface upon which the concrete is supported without the use of the usual w ter tight forms. f

' The ollow tile being lighter than the ordinary' forms of tile, a lighterv centering can be used to support it. The 'centering usedv with my improved tile concrete construction may be made of strips of rough or lnotty lumber, the only requisite being that it shall present a substantially uniform surface upon which the tile may be positioned. The continuous smooth surface necessary when lconcrete is to 'be used with tile not having" the lateral ,flanges is unnecessary with m'y tile.

It is evident that my improved hollow tile unit can be used in other ways than those above shown and described, for exam le, in hollow walls o'r for furring, and I db not wish to limit myself to the precise forms of tile herein shown nor to the arrangement above described.

What I claim and desire to secure by Letters Patent is :l

1. A hollow tile unit composed of two tile sections comprising side portions and a connecting web portlon, the distance between the opposite sides of each section being as great as the length ot' the 'sides and web oi the 'other section, said sections being arranged with the sides of each embracing the web of the other, whereby one section constitutes the bottom'and two sides ofr the unit andthe other section constitutes the top and the. two remaining` sides of said unit.

2. A hollow tile unit composed of two tile channel sections of equal height, one of said sections being arranged to constitute the bottom and two sides of the unit and the other being arranged to constitute the top and two remaining sides of the unit, both the length and the distance between the opposite sides of the top section being equal to each other and also being equal to the length and the distance between the opposite sides ofthe bottom section, said sections interlocking with their sides straddling the top and bottom of the unit.'

3. A11-open end box tile having its side walls scored midway between itsv top and bottom, the clear distance between said side walls being as great as the length of theV tile, and a bridge wall connecting said side walls at points adjacent to said scores.

4."An open end box tile having its side walls scored midway between its top and bottom, the clear distance between said side walls being as great as the length of the tile, a bridge wall connecting said side walls at points adjacent. to said scores, and laterally extending' flanges on said sides along the lower edges thereof andV immediately above said scores.

5. A' hollow unit composed of two tiles of equal height arranged with their axes transverse to yeach other, each tile comprising a web and two oppositely arranged side walls, the side walls of each tile being spaced apart a distance equal to the length of the other tile and arranged to embrace the webof the other tile.

6. A hollow unit for composite structures, said unit being composed of two U-shaped tiles, one of which is inverted and placed at right angles to the other`between the upper edges of the side walls thereof, and the sidey walls of said inverted tile embracing the bottom of the other and terminating flush with the bottom surface of theunit.

7.,A hollow unit composed of two tiles arranged with their axes transverse to each other, each tile comprising a web and two op ositely arranged side walls, the side wa ys of each tile being spaced apart to embrace the web of, the other tile, -and the side walls of each tile terminating beyond the inside faceof the web of the other tile.
