WALL-TAPE.

Specification of Letters Patent.

Patented Nov. 2, 1920.

Application filed March 17, 1920. Serial No. 366,550.

To all whom it may concern:

Be it known that I, JOHN SoHUMAcnnn, a citizen of the United States, residing at Los Angeles, in the county of Los 'Angeles and State of California, have invented new and useful Improvements in \Vall-Tape, of

which the following is a specification.

The invention relates to a flexible tape, and is especially adapted for covering joints, fissures, or cracks in flat surfaces. The tape embodying this invention is especially suitable for use with wall board, on plastered surfaces, and the like. Wall board is delivered in the form of plates for installation by attaching it to the wall of a rooni orbuilding to form The joints between the sections may be filled with a cement putty to present a smooth surface, or strips of paper may be pasted over the joints, fissures or cracks. Fissures or cracks in plastered surfaces and the like may also be covered with strips to conceal the same. Such strips are commonly of uniform thickness and when placed in position, the strips project beyond the surface, shoulders being formed at the sides thereof. This makes. the strips visible and unsightly. It is the primary object of this invention to provide a tape or strip, which may be placed upon and will adhere to a surface, and which has a thickness so distributed that no shoulders will be formed at thejunction of the tape with the surface, the two merging. .It is another object of this invention to provide an adhesive tape of the character described.

I accomplish these objects by means of the embodiment of my invention illustrated in the accompanying drawing, in which:

Figure 1 is a perspective view showing fragments of wall board sections with a joint covered by my improved tape; F ig. 2

is a ers )ective view showin In improved tape applied to an otherwise exposed edge of a plaster board unit; Fig. 3 1s a perspective view of the tape.

Referring more particularly to Fig. 1,'A

and B indicate units or sections of plaster board; preferablygmade ofplaster placed between fibrous covering. This kind of plaster board is well known in the art. A joints is formed between th units A and B. In order to present 'a finlshed surface, the joint should be filled or covered. For this purpose, I have sho'wn-myyimproved tape 5 placed This tape is preferably, of fibrous material such as paper of the character used in the covering for the plaster 1 which form in plastered walls.

board. j The tape preferably has a flat undersurface wlth an adhesiveapplied thereto.- The upper surface is preferably convexed intersecting the lower surface, so that knife ed es are. formed on the tape.

It is obvious that when the tape is placed in. position, the upper surface thereof merges with the surface of the plaster board. A finished surface i thus produced wh ch has no shoulders or irregularities.

When the surface is tinted, or papered, it

appears smooth and continuous.

In Fig. 2, the tapeis shown applied to an otherwise ex osed edge of the plaster board. Units of plaster board commonly are produced with exposed edges. There is an-u peer and a lower coverin of paper; but tl fe edges present exposed plaster It would be advantageous to cover the edgesto present a surface with less asperities, and also as a protection against chipping and the absorption of moisture. 0 indicates the plaster board and 8 an edge. The tape 9 is pasted over the edge and the ends 10 and 11 thereof folded over the covering sheets 12 and 13. The junction of the tape with the covering sheets is such that no irregularities in the surface are apparent.

In the drawing, sizesare exa gerated to All of the exposed edges may be covered in this manner, if desired. The tape is also suitable for covering cracks and fissures As the tape is preferably formed of fibrous material having some resiliencyand being flexible, any'change, such is likely to occur. in the fissures or cracks will not disturb the tape in a way to make such changes visible.

It'is within the scope of my invention to taper the surfaces and form a knife edge on either or both edges of the tape.

What I claim is:

l. A tape for walls comprising a strip of flexible fibrous material having an upper surface and a lower surface tapering and A intersecting in a knife edge.
