SPECIFICATION forming part of Letters Patent No. 728,525, dated May 19, 1903. Application filed April 13,1901. Serial No. 55,691. (No model.)

To aZZ whom it'maty concern:

Be it known that I, GEORGE W. WALTERS, of Elliott, in the county-of Allegheny and State of Pennsylvania, have invented a new and useful Metallic Mat, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specification, in which- I to Figure lis a fragmentarytop plan view showing a portion of my im proved mat. Fig. 2 is a cross-section on the line II II of Fig. 1. Fig. 3 is a view similar to Fig. 1, showing a modified form. Fig. 4 is a view of a complete mat constructed in accordance with my invention. y

Myinventlon relates to that class of'metallic mats wherein metallic strips are employed which are bent into zigzag or irregular shapes 2c and held so that the shoe contacts with the edges of the strips, and its object is to simplify, cheapen, and improve such mats and make them more resilient and elastic.

In the drawings, referring to the form of Figs. 1 and 2, I show a series of metal strips 2, each of which is bent into alternate V form. The strips are arranged so that the apices of the V-shaped bends meet or register,and these strips are held in position by wire helices 3, which extend through the line of the junctures, while their coils embrace the abutting apices of the V-shaped bends. In order to provide for the reception of the coils at the points where they grip the strips, I preferably cut 5 away the edge portions or the strips at such points, as shown at 4 in Fig. 2.

The end of the mat may be finished in any desirable manner; but I prefer to employ a two-ply strip 5, through which extend staples 4Q 6, which engage the apices of v the end strip, the legs of the staple being bent in opposite directions within thetwo-ply finishing-strip. The edge portions of this strip may be doubled in and hemmed down to give a smooth finishing-strip, as shown in Fig. 2.

In Fig. 3 I show a form similar to that of Fig. 1, except that the adjacent apices of successive strips are arranged in alternate fashion and not abutting, as in the form of Fig.

1. In this form also the strips 2" are held tosents a neat and attractive appearance.

The strips may be bent in many different shapes other than the V shape shown, and the arrangement and connection ofthe strips'and spiral springs'may' be varied' widely without departing from my invention.

I claim- 1. A metallic mat composed of strips ofsheet metal bent into a series of figures, and wire helices extending between the strips and engaging cut-away portions of said strips; substantially as described. p

2. A metallic matcontaining a series of metallic strips bent into V-shaped figures, and wire helices extendingbetween the strips and. engaging cut-away portions at the apices of said figures; substantially as described.

3. A metallic mat comprising alternate strips of metal bent into zigzag shapes, and spiral springs engaging said strips, and a finishing-strip extendingalong the end of the mat and secured to the zigzag portions of one of the metal strips; substantially as described.

In testimony whereof I have hereunto set my hand.
