FASTENER FOR SHEET FABRICS.

Specification of Letters Patent.

Patented Apr. 11, 1916.

Application filed May 14, 1915. Serial No. 28,013.

To all whom it may concern Be it known that I, MOREE GREEN, a citizen of the United States, residing in St. Louis and State of Missouri, have invented certain new and useful Improvements in Fasteners for Sheet Fabrics, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in fasteners for sheet fabrics, and has for its object to provide means for securing the edge of a sheet of fabric to a suitable support.

In the drawings Figure 1 is a plan View of the fastener of my invention applied to a rectangular frame to hold in place therein a rectangular sheet of fabric. Fig. 2 is a transverse sectional view of the fastening device of my invention in place. Fig. 3 is a perspective view of the fastening device of my invention.

As shown in the drawings, I employ the base or support 4 having the channel 5, a bearing face 6 and a rear face 7 whose plane is parallel with the plane of the face 6, these planes being so related that the outer wall 8 of the channel 5 is deeper than the inner wall 9 of said channel 5 (see Fig. 2).

The fastening strip 10 is formed of a single sheet of resilient material whose outer edge is folded over upon itself to form the lap 11. To the rear of the lap 11 the sheet is formed into the arch 12. To the rear of the arch 12 the metallic sheet is bent upwardly and then downwardly to form the hump 13. Beneath the hump 13 the metallic sheet is again bent upon itself to form the spring 14, and its lower edge is curled to form the roll 15. The structure of the strip member 10 is shown in detail in Figs. 2 and 3, and its application to hold the fabric 16 in place upon the base 7 is specifically illustrated in Fig. 2. The inner edge of the Copies of this patent may be obtained for fabric 16 is held at the bottom of the channel 5 by the roll 15, the spring 14 is of such dimensions that its apex impacts against the fabric 16 to hold it in place against the front wall 9 of the channel 5, the hump 13 abuts against the rear wall 8 of the channel 5 to form a substantially waterproofed joint or closure for the channel 5, while the lap 11 bears downwardly upon the fabric 16 to hold it firmly against the face 6 of the base or support 7.

When the strip 10 is applied to a frame, it is used as illustrated in Fig. 1, a triangular section being cut and removed from the lap 11 and arch 12 so that the strip 10 may be bent upon itself to form the joint indicated in Fig. 1 by the numeral 17 The uses of my invention are various; it may be used to secure window shades to their rollers, to secure wire mesh in place within a frame, or it may be used to hold relatively inflexible sheet material, such as glass, in place within a frame. By the use of my invention the use of nails, screws or other securing elements is dispensed with, no cutting edge is presented to the fabric, and the strip 10 may readily be removed from the seat for the purpose of replacing the sheet fabric with new material.

Having thus described my invention,

what I claim as new and desire to have secured to me by the grant of Letters Patent, is

The fabric fastener comprising a base having a channel whose outer wall is deeper than its inner wall; in combination with a strip formed from a single sheet of resilient material bent to form an outer lap, a rear hump, an arch connecting said lap and hump, a spring depending from said hump, and a roll formed upon the lower edge of said spring.
