MAT.

Specification of Letters Patent.

Patented Aug. 4, 190s.

Application mea May 22, 190s. serial No. 318,202.

To all whom it may concern:

Y Be it known that I, THOMAS C. MOPHER- soN, a citizen of the United States, residing at Beaver Falls, in the county of Beaver and State of Pennsylvania, have invented a new and useful Mat, of which the following is a specification.

This invention relates more particularly to metallic mats, and is in the natureof an improvement on the mat disclosed in application, Serial No. 303,507, filed Feb. 21, 1906. The principal object in the present case is to provide novel reinforcing devices that will secure rigidity in the mat, and prevent its becoming misshapen, said devices being so formed that they may be readily placed in position, will accommodate themselves to in-y accuracies due to the formation of the mat strips, and will produce a more ornamental effect.

In the accompanying drawings z-Figure 1 is a plan view o a portion of a mat, showing the improved reinforcements forming 4a part of the same. Fig. 2 is a detail horizontal sectional view therethrough. Fig. 3 is a lan view of a slightly different form of mat avinthe reinforcements therein.

imilar reference numerals designate corresponding parts vin all the figures of the drawings.

In the embodiment Villustrated in the first two figures, the mat is composed of sections 4, each section comprising a tortuously formed sectional strip, the said sectional strip being bent into oppositely dis osed open loops 5, forming longitudinal side web elements 6 and cross webs. The closed ends of the loo s 5 of one section enter the open ends,

of the oops of the adjacent section. Pivot .rods 7 connect the adjacent sections, said againstthe adjacent longitudinal Web elements 6 of the mat section. The end webs in like manner abut against the end Webs of the evices consist` loops in which they are placed. One ofthe pivot rods 7 passes through the outer ends of said portions 10. The doubled end 11 of the through the doubled end, as shown so that the cross web of the reinforcement is located between the pivot rod and the cross web of the loop in which said reinforcement is located.

The same reinforcements are shown in a slightly different form of mat in Fig. 3. In this structure the oppositely disposed loops 5a of the mat sections 4a are formed from a continuous strip instead of a sectional strip, and the free ends 'of the end loops are separated by coiled springs otherwise the structure is substantially the same.

There are several distinct advantages for the peculiarly shaped reinforcing devices. In the first place, they can be much more quickly placed in position than the devices shown in the application to which reference has been made. In forming the loops 5 and 5a' of the mat sections, the dies in time become worn, and consequently the width of the doubled ends will vary. With the plain U-shaped devices, such as are shown in the From the foregoing, it is thought that the construction, operation, and many advantages of the herein described invention, will be apparent to those skilled in the art, Without further description, and it will be understood that various changes in the size, shape, proportion, and minor details of construction, may be resorted to without departing from the spirit or sacrificing any of the advantages of the invention.

I-Iaving thus fully described my invention, What I- claim as new, and desire to secure by Letters Patent, is

1. In a mat, a plurality of sections comprising reversely disposed loops, certain of the doubled ends of the loops of one section being located in the open ends of the adjacent section, pivots passing through said doubled ends and being spaced from the doubled portions thereof, and reinforcements located inthe end loops of each section and having side portions located against the sides of the same, said reinforcements having doubled portions engaged with the pivots and disposed in spaced relation to the sides of the section loops, in which they are located being furthermore located in the spaces between the pivots and the doubled ends of the section loops,

2. A mat comprising a plurality of sections, each section consisting of a strip formed into oppositely disposed loops having open and closed ends, reinforcing loops located in the terminal loops of each section and having open ends, the open ends of the section loops in which they are located being furthermore provided with closed ends of less width than the closed ends of the section loops in which they' are located and. abutted against said closed ends while spaced from the sides of said section loops, the closed ends of the loops of one section entering the open ends of the loops of the adjacent sections, the closed ends of the terminal loops in like inanner entering the open ends of the reinforcing loops of the adjacent sections, and pivots passing through said ends and constituting connections between the various sections.

In testimony, that I claim the foregoing as my own, I have hereto ailixed my signature in the presence of two witnesses.
