TILE
Filed March '13 1925 INVENTOR i ARTHUR AHEEEEN 5 3417? WWI/MA ATTORNEY Patented Jan. '5, 1931 PATENT Fries ARTHUR A. HEEREN, OF CHICAGO, ILLINOIS, ASSIGNOR 'IO UNITED STATES GYPSUM COMPANY, OF CHICAGO, ILLINOIS, A CORPORATION OF ILLINOIS TILE Application and March 13, 1925. Serial No. 15,239.
This invention relates to improvements in buildin construction and more particularly to an Improved form of tile used in fireproofing steel beams and the method of manufacturing the same. a
The fire-resisting qualities of calcined gypsumhave long been recognized and rectangular tiles of this material have been in eneral use for sometime for the erection of partiw tions and for surroundingsteel beams in floor, roof and wall constructions to render them fireproof or fire-resisting.
It is an object of this invention to provide a calcined gypsum tile that is particularly adapted to fit around the base flanges of I beams used in building construction and which will act as a support for rectangular tile protecting the webs of such beams.
While the preferred form of this invention go is illustrated on the accompanying .sheet of drawing, yet it is to be understood that minor detail changes may be made without departing from the scope thereof.
In the drawing: Figure l. is-a view in perspective of a floor or roof I beam illustrating an application of the flange surrounding tile in accordance with this invention.
Figure 2 is an enlarged detail view in cross section illustrating the same. I
Figure 3 is a view in perspective of the double tile as it is moulded. v
Figure 4 is a horizontal sectional view of a tile mould with the core in place.
Figure 5 is a transverse vertical sectional view through a tile. mould, illustrating a tile therein and the core, in side elevation.
As shown in Figures 1 and 2 the tiles 1 and I 2 are each provided with similar recess to receive the opposite members of the base flange of the I beam 3, each having horizontal portions 4 parallel to the bottom of the tile to pass under the. bottom of the I beam flange and angular portions 5 to pass above the top of the said flange, with the horizontal portions beveled, as at 6, to the vertical edges and the distance between the outer and inner ver tical edges of the tile greater at the bottom than at the top, so that approximately the same amount of mortar or other binder may be applied between each upper vertical edge and the adjacent surface of the web as between the lower vertical edges of the opposite tiles, and the beveled corners forms a key for the binder on the lower side, as shown.
It will be seen that the tile embracing one flange is the reverse-of the tile embracing the opposite flange and it has been found that by making the inner adjacent vertical edges of equal length, one tile when inverted will form a rectangular block with the other and therefore can be cast in one piece, as shown in Figure 3.
Calcined gypsum when mixed with water forms a plastic mass which may be moulded or cast and having assumed a definite shape will set and in drying out will maintain that shape. This invention contemplates the casting of a pair of tiles in a mould 10, such as illustrated in Figures 4 and 5, having a stationary core 11 and a movable follower 12. The core is provided with surfaces 14, 15 and 16 corresponding to surfaces 4, 5, and 6 of the tile shown in Figure 2 and two opposite sides of the mould are provided with vertical ribs 17 on the sides adjacent the meeting edges of surfaces 15 and 16 of the core which will form grooves 18 in the cast block. 'lhe mould is filled with the plastic material and after it has set suiliciently to hold its shape the follower 12 is moved upward to eject the formed article in the form shown in Fig ure. 3, which is removed to a drying kiln or otherwise allowed to dry.
The block in this form is readily cut by a saw along the lines of the grooves 18 to form two tiles, or by lifting the block and bringing it down upon a straight edge along the groove 18 with suihcient force it will readily separate in vertical lines through the grooves to form a pair of tiles for the opposite flanges of an I beam.
A gypsum tile of this character when moulded in this manner maintains its contour and its flat surfaces do not change in drying so that a close fit can be obtained u on the fianfges of structural angle irons. 'l his form 0 tile is particularly designed to be applied to I beams, as illustrated, and while the general shape of the flanges of I beams LC) to iron flange and having opposed outer sur- ,remain the same the width of the base flange varies with the thickness of the web in different strengths of beams. By forming the tile with' its upper horizontal surface less than its lower horizontal surface, referring to end one of the sets of parallel surfaces,
"small angular inwardly projecting dinal grooves on opposite sides, wit
adapted by a blow along one of the outer grooves to separate into two tiles with the apertures forming reverse recesses in the tiles to receive the flange of structural irons.
2. A pair of shoe'tiles cast diagonally opposite in a rectangular block, each tile having a recess in one sideshaped to receive a structural iron flange; the block having longituacentral recess having two diametrically opposite surfaces parallel to thesides of the block, and two sets of diagonally opposite surfaces angularly related to said parallel surfaces,
meeting each other on the sides of the recess adjacent to the longitudinal grooves and joining at each outer end one of the said parallel surfaces.
3. A rectangular shoe tile block haying angular longitudinal grooves in opposite sides and a central recess, the diagonally opposite sides of the recess each having a portion parallel to the outer surface of the block, andv an angular extension, the apex-of which is adjacent v to the groove in the side, the notches and an ular'extensions providing means for breakmg each block into two sim- (ilar tiles each having one side longer than the other.
4. A gypsum tile having a flange recess in one side shaped to receive a structural faces parallel to the bottom. of said flange recess with the width of the surface immediately adjacent thereto, being greater than the other of the opposed surfaces and the outer edge of the bottom of'said flange recess being beveled.
5. A cast gypsum shoe tile consisting of two integrally cast portions, severable from each other, each portion when so severed comprising a longitudinally recessed tile, the
outer faces of said tile being parallel to each other, one side of said recess being parallel to the faces of the tile and the other side of the recessbeing inclined relative to the other side, one side of said tile being broader than the other side of the tile.
6. A calcined gypsum-tile having a recess in one side shaped to receive a structural iron flange and having opposite outer surfaces parallel to the bottom of said flange recess withthe width of the outer surfaces adjacent to the bottom of said flange recess being greater than the widthof the other of said opposite surfaces and a surface including a beveled portion oining the bottom of said flange recess ,to the said outer surface of greater width.
. 7. An integrally cast tile of cementitious material hav ng outer longitudinal rooves formed in two 0 posed faces thereo and a single centrally isposed opening of irregular configuration extending longitudinally of the tile, said tile being severable alon said outer grooves into two substantially s1milar portions, each having a longitudinal recess and opposed outer faces parallel to each other,"
one side of said recess being parallel to said opposed'outer faces and another side of said recess being inclined relatively to said opposed outer faces, one. of said opposed outer faces being of greater width than the other.
8. An integrally cast title of cementitious material having outer-longitudinal ooves formed in two opposed faces thero and 'a centrally disposed opening of irre ular configuration extending longitudinal y of the tile, said tile being. severable alon said outer grooves into two substantially similarv por- 'tions, each having a longitudinal recess and opposed outer faces parallel to each other, one
. side of said'rec'ess being inclined relatively to said. opposed outer faces so as to coincide substantially with the inclination of a flan e of a structural iron, and ,one of said oppose outer faces being of greater width than the other.
