JOHN A. SLOAN, OF TRENTON, NEW JERSEY.

MANUFACTURE OF TILING.

Specification of Letters Patent.

Patented Sept. 19, 1905.

Application filed August 9, 1904. Serial No- 220,071.

To all 1077,0771, it may concern.-

Be it known that I, JOHN A. SLOAN, a citizen of the United States, residing at Trenton, in the county of Mercer and State of New Jersey, have invented certain Improvements in the Manufacture of Tiling, of which the following is a specification.

This invention relates more particularly to tiles for covering floors or the like of such character that they can be cut from sheeted material without waste and joined together in interlocking relation to form a covering that will not separate at the joints under longitudinal strains.

Particularly in the manufacture of rubber tiles the operation of punching elfects a Wedging result, due to stretching the material, producingtiles that do not join properly, and there is considerable waste, which it is desirable to avoid. In molding tiles the operations are slow and expensive, and variations desired in the thickness of the product, as well as in the configuration, require new sets of molds.

In the present improvements, through the peculiar configuration of the tiles and the peculiar mode of operation employed in producing the same, sheeted material may be cut rapidly and inexpensively into shapes that will interlock, of any desired thickness, without waste, and the several shapes may be joined together so as to firmly resist the tendency to separate laterally in whatever direction.

In the accompanying drawings, Figure 1 is a plan view representing a tiling made in accordance with my improvements. Fig. 2 is a plan view representing the contour of the edge of the knife employed and the sheet cut thereby. Fig. 3 is a plan view representing a sheet similar to that shown in Fig. 2 after subjection to the succeeding cut of the knife by which a row of tiles is produced,

and Fig. i represents a perspective View of one of the series of tiles shown in Figs. 1 and 3.

As shown in the drawings, each of the several tiles is symmetrical with reference to axes at right angles with each other, being composed of a body 1, having the oppositely extending projections 2 defined, respectively,

by intersecting reverse curves 3 and the opwhose respective centers are the intersections of the revolved curves with lines joining the axial points 6 and 7 The fluke-like projections 8 thus formed have between them and the body portion the rentrant portions 9, fluke-like in outline and. duplicate of the form of the projections 8. The rentrant portions 9 of each tile are adapted to receive projections 8 of duplicate tiles, the body contours 3 of the respective tiles fitting end contours 5 of others joined thereto. Each tile is thus adapted for directly engaging in interlocking relation with four others surrounding it, producing a fabric composed of shapes connected together so that their joints cannot separate along any line or lines, as illustrated in Fig. 1.

In the operation of cutting the tiles the blade employed, having an edge corresponding in outline to the repeated curves 3 and 5, effects an initial cut, as shown in Fig. 2. The

succeeding cut, which strikes off a row of tiles of the character described, as shown in Fig. 3, is effected by shifting laterally and longitudinally (or diagonally) through a half-length and half-width of a tile either the knife or the goods, bringing the points of the knife that have formed the points at the intersections of the lines 3 in the first cut to position for registration with the points of intersection of the lines 5 thereof. It will now be understood that tiles may thus be cut inexpensively, rapidly, and without waste from sheeted material, each tile being adapted for interlocking with others surrounding it to form a covering of pleasing, nicely-joined, and not readily separable character, the several tiles having the symmetrical form permitting them to be reversed in position on account of wear, defect, or other reason therefor.

Having described my invention, I claim- 1. In the manufacture of tiling, a tile defined by reverse curves intersecting on axes at right angles to each other, said tile being symmetrical with reference to each of said axes, substantially as specified.

2. In the manufacture of tiling, a tile having lateral projections defined by intersecting curves symmetrically arranged with respect to an axis and ends having reentrant curves continuant of the curves of said projections, substantially as specified.

3. In the manufacture of tiling, a tile having lateral projections defined by intersecting curves and ends having rentrant and projecting portions whose curves are continuant of the curves of said lateral projections and symmetrically arranged With respect to-anaxis, substantially as specified.

4. In the manufacture of tiling, a tile having body projections defined by intersecting curves, reentrant portions defined by curves continuant .of said intersecting curves, and end projections defined by curves similar to and continuant of the curves ofsaid reentrant portions, said tile being symmetrical with.

respect to two axes, substantially as specified.

5. In the manufacture of tiling, a tile having body projections defined by intersecting reverse curves and ends having projections defined by curves continuant of said reverse curves, the curves of the ends duplicating the curves of the body, substantially as specified.

6. In the manufacture of tiling, the combination of a series of similar interlocking shapes having" curved outlines, each symmet- JOHN A. SLOAN.
