To all whone it may concern:

Be it known that I, BERNARD LOND- KOWSKI, a citizen of the United States, residing at Milwaukee, in the county of Milwaukee and State of Wisconsin, have invented certain new and useful Im rovements in Metallic Mats, of which the fo lowing is a specification, reference being had to the accompanying drawings, forming a part thereof.

My invention relates to mats, and particularly to that class known as metallic floor or door mats Its main object is to provide a durable and efficient mat which is adapted to be compactly folded either lengthwise or crosswise.

A further object of the invention is to pro- Vide a large amount of scrapingesurface in a small area of matting with the use of a comparatively small number of joints, thus requiring fewer rivets and reducing the cost of manufacture accordingly.

It consists in certain novel features of construction and in the peculiar arrangement of parts hereinafter particularly described, and pointed out in the claims.

In the accompanying drawings like letters designate the same parts in all the figures.

Figure 1 is a planview of a portion of a mat constructed in accordance with my invention. Fig. 2 is a section view taken on line 2 2, Fig. 1. Fig. 3 is a View similar to Fig. 1 of another form of my invention, and Fig. 4 is an end view of the latter.

The body portion of the form of mat shown in Figs. 1 and 2 consists of a number of links or sections a, b, and 0, preferably made of flat narrow metal bands which may be galvan ized, joined together to form meshes d, which are in turn pivoted to adjoining meshes by means of suitable pivots or rivets e. The links a and b consist of bands or strips of metal of suitable Width bent into any desired shape, preferably angular, as shown, and having apertured ends f and g, one of which on each link is made somewhat longer than the other. The object of making the ends f longer than the ends 9- is to prevent cramping the joints when the links forming the meshes are connected. Hence the long end of each link is placed and riveted adjacent to the short end of the adjoining link in the same mesh throughout the series. Links a and 1) form one half of each mesh d and links 0 the other half. Link 0 is similar in size and shape to links a and I), placed end to end, as shown in the drawings, and is similarly provided with two a ertured ends h and i, one of which is longer t an the other for the reason stated. An additional reasonfor this method of construction is that it admits of somewhat more play between the joints when the mat is folded, permitting closer or more compact foldin of the same than would otherwise be possib e. The border of the mat is composed of meshes j, k, and Z, the first one of which is formed of the same number of links and in the same manner as meshes d and alternates with meshes k on two opposite sides of the mat until a corner-mesh Z is reached. Meshes k comprise two similar links 0, joined in the same manner, and the corner mesh Z, of

which only one is shown, is formed of a link 4 a and a linkmof any desired or suitable shape, but preferably of the angular form shown in Fig. 1 of the drawings, having one long aper tured attaching end it and one short end 0 joined to the link a and the adjoining meshes in a manner similar to the balance of the construction.

Although the form of mat shown in Figs. 1 and 2 and just described will serve its pur pose satisfactorily, the form shown in Figs.

3 and 4 is somewhat more simple in construc.

tion, requiring but two links to each mesh throughout instead of three, as used in the body portion of the other form shown. Four forms of meshes a, b, c, and d are shown, of which mesh a is composed of links 6 and f, the former being similar to link 0 in the other form of mat and link f more like links a and b, but looped or bent back upon itself where the two ends of links a and I) join. Thus it will be seen that the shape or form of meshes d and a are ractically alike. Meshes 1) are composed of inks f and border-links g, which latter, however, may be formed like the link 6, if desired, to lessen the number of dies required in the construction of this form of mat. The links forming the meshes are joined together by means of rivets j. Mesh c, of which but one is shown, is composed of links 6 and a border-link g, and corner-mesh d, of which only one is shown, comprises link h, similar to links a. and b in Fig. 1, and a special form of corner-link a", which, however, may be made in any suitable form or in the shape of the corner-link m. (Shown in Fig. 1.)

The mat shown in Figs. 3 and 4 is assembled'with the long and short ends of the various links in the same relative positions shown in Fig. 1, and the same advantages of non-cramping joints, closer and more compact folding, small number of riveted joints,

and an edge or wearing surface composed of a large number of angles adapted to catch 5 and remove the mud and dirt from the soles of foot-gear Worn by persons using the mat pertain to this as well as to the other form of mat.

Although in the foregoing both forms of 10 mats have been described as consisting of galvanized metal, it is obvious that it is quite practicable to cast or otherwise form the links where amat of extraordinary durability and strength is required. In short, various I 5 modifications in the details of construction meshes which are pivotally connected with each other at three points only, substantially as described.

3. A metallic mat composed of a series of meshes formed of links each of which is bent into angular form and is provided with one short and one long perforated attaching end, the short end of each link being adjacent to the long end of the adjoining link in the same mesh, and the links of each mesh being pivotally connected with links of adjoining meshes at three points only, substantially as described.

4. In a metallic mat a number of links joined together and forming meshes, each mesh of the body portion of the mat being pivoted to adjoining meshes at three points only, and a border in which every other mesh on two opposite sides of the mat and the corner-meshes are pivoted to adjoining meshes at two points only, substantially as described.

In witness whereof I hereto afliX my signature in presence of two witnesses.
