fOhio Application April'l'l. 1939.seriaiNaassnm 2 Claims. (01. 29--89) Thisrinvention relates: ingeneral to floormats and more particularly to new and useful devices for manufacturing floor mats made up from transversely arranged, spaced, perforated links to a flexible mat structure. In these mats the links of fibrous or rubber-like material according to present day manufacturingimethods are mounted one by one on connecting rods orpintles,.preferably of U-shape, until all links are threaded upon the rods, and then the ends of these rods are rectangularly bent and united together to finish the thus made matstructure. However, this manufacturing method for floor mats is slow and costly and, in addition, makes production of properly 1?) sized, flexible mats rather difiicult, due to the fact that the operator controls lateral compression of the links when the ends of the connecting rods are bent after assembly of the links.

It is the primary object of the present inven- 20 tion to simplify manufacturing of floor mats of the type referred to by providing an assembly board adapted to effect proper location and alignment of perforated links prior to their assembly to a mat and permitting of connecting 25 rods being threaded through the localized and aligned perforated links in a simple and eflicient manner, so as to rapidly produce a finished mat structure.

Another object of the invention is the provision 30 of an assembly board for floor mats having a plurality of symmetrically arranged, specifically sized overlapping recesses, each of which permits of a link being placed therein, the recesses being arranged in overlapping relation with re- 5 spect to each other for effecting threading of links placed into adjoining recesses by elongated connecting rods extended through the aligned perforations of said links.

A further object of the invention is the provi- 40 sion of an assembly board for floor mats having a plurality of symmetrically arranged, equally sized, overlapping recesses in its top face permitting of proper assembly of links to a floor mat structure, said assembly board having its re- 45 cesses extended to the top of the board and including lateral plain extensions in the plane of the recesses for permitting of excessively sized floor mats being assembled and manufactured on said assembly board.

so In addition, the invention has certain other marked superiorities which radically distinguish it from presently known structures. These improvements or superiorities embodying certain novel features of construction are clearly set g5 forth in the following specification and the appended claims; and a preferred form of embodiment of the invention is hereinafter shown with reference to the accompanying drawings forming partof the specification.

In the drawings:

Fig. 1 is a plan View of the working and assembly board according to the invention.

Fig. 2 is a longitudinal sectional view through the board shown in Fig. 1, the section being taken on line 22 of said figure.

10" Figure 3 1s a cross sectional view through the board shown in Fig. 1, the section being taken on-line 3-3 of said figure.

Fig. 4 is a plan view of the board shown in Fig.

' 1 with links placed in the recesses of the board and partly assembled to a mat structure.

Fig. 5 is a perspective view of one of the links used in the mat structure.

Fig. 6 is a perspective view of one of the metal end plates of the mat.

Fig. 7 is a perspective view of a connecting rod.

Fig. 8 is a perspective view of one of the end rolls of the mat; and

Fig. 9 is a perspective view of the clip used to interlock the bent ends of the connecting rod shown in Fig. '7.

Referring more particularly to the drawings reference numeral 2 represents a working and assembly board of any suitable material such as wood,iron or plastics. This board embodies a base plate 3 having four corners mounted on blocks or legs 4, and supporting a plurality of elongated strips 5, each of which is secured to transversely base plate 3 lengthwise thereof in any suitable manner. These strips each embody a plurality of equally spaced recesses 6 having straight end walls I, which recesses are arranged in the face of said strips and form in said strips a plurality of rectangular posts or elevations 8. In addition, the recesses in adjoining strips 5 are laterally and symmetrically offset with respect to each other to effect overlapping of the recesses in adjoining strips and arrange the posts or elevations 8 of all the strips in symmetric rows, rectangularly related to the bottom edge 9 of board 2. 5

The uppermost strip 5 on base plate 3 is substantially flush with the upper edge of said base plate and all strips 5, including uppermost strip 5', abut with their opposite ends edge borders H) on base plate 3, top faces I ll of which are arranged flush with respect to recesses 6 in said strips, all as clearly shown in the drawings.

The thus constructed working and assembly board 2 permits of individual links H being properly placed and located in recesses 6 of strips 5, as the offset relation of adjoining recesses in adjoining strips permits of holding the links at all sides in proper position and simultaneously effects proper alignment of the perforated ends I2 of links I I, so that perforations I4 in said links are aligned and permit of connecting rods I5 being readily and easily threaded through the perforations I4 of said links, see Fig. 4. Preferably, connecting rods I4 are of U-shape to expedite manufacturing and permit of most simple securing of said rods in the mat structure by bending the ends I6 thereof inwardly and securing the bent edges to each other by means of clips I'I. At the side edges the thus manufactured mat includes end rolls I8 which are also threaded on rods I5 and effect a symmetrical design of the mat at its edges, a destruction or cutting in of the end links by connecting rods I5 is prohibited by metal links I9 which are placed between rods I5 and links 5.

The edge borders 9 have their upper faces arranged fiush with recesses 6 of strips 5 to permit of mats of any desired length being readily assembled on the board. Thus, when mats of excessive size are to be manufactured, the mat is made in sections, first one section of the mat is finished in the manner above described and then the finished section of the mat is moved laterally and secured in one or more rows of recesses of the board, whereupon manufacturing of the next section can readily be eifected on the board. This procedure of manufacture is also usable for mats having excessive width, as the uppermost strip 5' is arranged flush with the upper edge of base plate 2 and permits also sectional manufacturing of the mat in the direction of its width.

It will now be seen that the thus described working and assembly board permits of manufacture of floor mats of any size and width in a simple and economic manner by unskilled operators and even blind operators, as the recesses 6 and square posts 8 permit of proper assembly of mats by mere touch.

Having thus described my invention, what I claim is:

1. An assembling and working board for floor mats comprising a base plate, a row of elongated posts extending across one face of the base plate from one end thereof to the other and all elongated in the direction of the row, said posts being spaced from each other a distance greater than the said length of a post, and additional rows of similar posts parallel to said first row and situated side by side, with the posts of each row staggered in relation to the posts of adjacent rows to provide channels across the rows.

2. An assembling and working board for floor mats as described in claim 1 including at one side of said base plate an elongated plain area (without posts) to permit of assembling of excessive long floor mats on said board.

3. An assembling and working board for floor mats as described in claim 1 including at one side and the lower portion of said base plate elongated plain areas (without posts) to permit of assembling of excessive wide and long floor mats on said board.
