SPECIFICATION forming part of Letters Patent No. 629,337, dated. July 25, 1899. Application filed April 20,1899. Serial No. 713,728. (No model.)
To all whom it may concern:
- Be it known that LWALTER OARTWRIGHT,. a citizen of the United States, residing at- New York, (Brooklyn,) in the county of Kings and State of NewYork, have invented cer-' tain new and useful Improvements in Tiles,
of which the following is a specification.
This invention relates generally to tiles and specifically to that form of tiles known technically as the angle-beadsthat is,the tiles used in finishing the corners where angles are formed by the flat tiles terminating. The object of this invention is to obviate the present dificnlties encountered in tiling corners, which is principally the tendency of said tiles to fall off when subjected to excessive heat or moisture. When the ordinary angle-bead is placed in position, it rarely presents its entire inner surface to perfect con: tact with the cement and will in consequence be easily loosened and either fall off or shift its position and destroy the symmetry of the tiled surface. 7
This invention discloses an angle-bead provided on its back with ananchor or formation 7 adapted to be buried in the cement in such several figures.
In the construction and application of my invention 1 is a rough brick or stud partition having a scratch-coat of cement 2, secured to lathing of any desired kind.
-3 is a backing or'body of cement in which the flat tiles 4 are laid and by means of which they are held in position.
r 5 is the an gle-bead,'presentii1g rounded outer and inner surfaces Band 7 5 respectively. The surfaces 8 of the angle-bead abut the flat tiles when said angle-bead is placed in its proper position, as indicated in Fig. 1. The anglebead is preferably made thicker than the flat tiles,so that fiat tiles of varying thickness can be employedand the outer-surface alinement of thetiles be preserved. The angle-bead is always forced intothe cement 3 until the outer surface 6 thereof is flush with the fiat 'tiles 4. Bymaking the angle-bead of greater thickness than the fiat tile the cement 3 is allowed to come in contact with the surfaces 8, and thereby form a more positive anchor.
Extendingoutwardly from the surfaces 8, are longitudinal ribs 10, which are embedded in the cement 3 and are designed to form the anchor proper for the angle-bead. The cement 3 will be squeezed in between the ribs --moved or loosenedby the varying conditions of the atmosphere or in cleaning or in the settling of the walls."
In Fig. 3 I have shown a modifiedform of anchor for the angle-bead; wherein a central longitudinal rib 12 is used in addition to the longitudinal ribs 10. I This central rib 12 is narrowest transversely where it connects with the angle-bead, so that when the anglebead is forced into the cement said cement will bear against the surfaces 13 on the cenand the flat tiles, so that after the cement has set the angle-bead will be securely antral rib, thereby making an additional anchor.
In Fig. 4 a further modified form of the anglebead is shown, whereina series of formations 14 are used that arev similar in cross-section'to the central rib 12, Fig. 3, and are held by the cement 3in the same manner as said central rib.
Having thus described my invention, what I claim as new therein, and desire to secure by Letters Patent, is-
An angle-bead of greater thickness than the flat tile and having curved inner and outer surfaces, longitudinal ribs on the inner surface and the fiat surfaces of said angle-bead adapted to abut the terminating ends of the flat tiles as explained.
