SPECIFICATION forming part of Letters Patent No. 742,918, dated November 3, 1903.

Application filed February 28. 1903. Serial No. 145,457- (No model.) l

To all whom t may concern:

Be it known that I, PETER J. sHRUM, of'

Pittsburg, Allegheny county, Pennsylvania, have invented a new and useful Mat, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings, forming part of this specication, in which- Figure 1 is a top plan view of a mat constructed in accordance with my invention. Fig. 2 is a perspective view showing one of the bent units. Fig. 3 is a single view of the doufble hinge-rod. Fig. 4 is a top plan view showing a portion of a modified form of the mat. Fig. 5 is a perspective view of one of the bent units of the form of Fig. 4. Fig. 6 is a top plan view showing a portion of another form of mat, andFig. 7 is a perspective view showing one of the bent units of Fig. 6.

My invention relates to the class of flexible mats formed of metal strips, and is designed to provide a simple, cheap, and strong construction which may be rolled or folded toward eitherface and which shall be 'attractive in appearance and efficient in action.

In the drawings, referring to the form of Figs. 1, 2, and 3,1 showa mat built up of sections hinged together, each section 2 consisting of a iiat metal strip bent into zigzag or alternate V-shaped form, the apices of the zigzags or Vs being twisted to form loops 3,

' the plane of the loops being at an angle, preferably a right angle, to the plane of any one of the legs. The sections are hinged together by means of the double hinge-rod 4 of Fig. 3, the two legs of which are threaded through the registering apices of the adjacent sections. The projecting ends of the hinge-wire are -then bent back to give a rounded end, and the spiral spacers 5 are coiled about the hinge-rods between the pairs of eyes or loops to hold them apart and keep them in proper position. These spiral spacers are preferably iiattened, and the wires are threaded through them as they are threaded through the eyes or loops of the adjacent sections.

At the ends of the mat the hinge-rods are preferably-arranged the same as between the sections, though the double hinge-rod may or may not be used at the end, as desired.

In Figs. 6 and 7 I show a further form wherein each section is built up of two strips 2b. Each of these strips is bent into zigzag form, preferably with wider angles than in previous forms, and midway of each leg the strip is twisted into a horizontal portion 7. When the two strips of the section are put together, their portions 7 engage or overlie each other, the eyes of one strip alternating with those of the other, as shown in Fig. 6. The double hinge-rod and the spacers may be used in the same manner as in the first form.

The advantages of my invention result from the simplicity and lightness of the mat, its capability of being folded toward either the upper or the lower face, and its attractive appearance.

Manychanges may be made in the form and arrangement of the parts without departing from my invention.

I claim- 1. A metallic mat formed of sections, hinge members to which the sections are hinged to form a exible mat, each section having meshes formed of bent metal strips provided with twisted eyes engaging the hinge members; substantiallyT as described.

2. A metallic 1nat having sections, hinge members to which the sections are hinged to form a iiexible mat, each section containing a continuous metal strip bent alternately in opposite directions, the apices of the bent portions being provided with eyes engaging the hinge members; substantially as described.

3. Ametallic mat having sections hinged to each other to form a flexible mat, each section containing a bent metal strip with twisted eye, and a double hinge-rod engaging the registering eyes of adjacent sections; substantially as described.

4. A metallic mat having sections hinged to each other to form a flexible mat, the sec tions having bent metal strips with twisted eyes, hinge-rods extending through the eyes,

and spacers surrounding the hinge-rod between the eyes; substantially as described.

5. A metallic mat formed of sections hinged together to form a flexible mat, each section containing a continuous metal strip bent 2Liternateiy in opposite directions, with twisted eyes at the apices, a double hinge-rod extending through the registering eyes of adjacent sections, and spacers around the hinge-rod between the eyes; substantially as described. In testimony whereof I have hereunto set my hand.
