DESIGN FOR A RUBBER DOOR-MAT.
SPECIFICATION forming part of Design No. 11,972, dated September 28, 1880.
Application filed June 'I, 1880; Term of patent 14 years.
To all whom it may concern:
Be it known that I, AUGUSTUS 0. 130mm, of Bristol, in the county of Bristol and State of Rhode Island, have invented and produced a new and original Design for Rubber Door- Mats, of which the following is a specification, reference being had to the aecom pan yin g draw-' ings, forming part thereof.
Figure 1 is a top view, and Fig. 2 a sectional view, of a door-mat which fully illustrates my design.
My design is composed of several components, all of which are applicable to that class of rubber mats vulcanized in molds, which impart to the mats their ornamental characteristics. The utility of raised ribs orlines, affording a rubbing surface on such mats, renders it important that such raised ribs or lines be so arranged or disposed with relation to each other as to best serve the purposes intended and I have therefore employed them as essential features in developing my ornamental design.
The outline of the mat may be rectangular, round, or oval, as may be desired.
The main feature of my design consists in the border A, composed of rows of diagonallymarked squares to, the diagonal marking thereof being produced by the raised ribs or lines 1).
Another feature of my design is in the particular arrangement of the ribs of each set of four square-s, a, said ribs, at the inner corners of the four squares, forming a small square, 0, surrounded by a series of similar squares progressively enlarged, the largest of these ribformed squares having sides which are of equal length with the central diagonal line of each of the four squares to, composing the set. It will be seen that with the ornamental effect thus attained the utility of the border as a foot-scraping medium is greatly enhanced,for the reason that the spaces between the ribs join other spaces at each end at an angle, thus practically precluding the scraping of dustand dirt from the mat to the floor by the foot.
The central field, cl, of the mat is also ribbed or corrugated; and while I claim said ribbed ornamentation of the field as a feature of my design in this particular mat, Ipropose to employ with my border various systems or styles of ornamentation for the central portion of the mat. The channeled line 0, however, I deem desirable for a finishing effect between the border and the central portion, however this latter may be ornamented. The boundary-lines f are also raised ribs, and these may be varied in number without detracting from the characteristic effect of my novel border.
Having thus described the several features of my design, I claim-- 1. The ornamental border for rubber doormats consisting of squares diagonally marked in raised lines, substantially as shown and described.
2. The ornamental border for rubber doormats consisting of rows of squares diagonally marked with raised lines, which form centrally in each set of four squares a raised-line square and a series of surrounding squares, substantially as described.
3. The design for a rubber door-mat consisting of the central field longitudinally ribbed and the border composed of squares marked in raised lines, substantially as described.
