IMPROVEMENT IN MECHANISMS FOR WEAVING MATS.

Specification forming part of Letters Patent N o. IGLGSI, dated April 6, 1875; application filed February 15, 1875.

To all whom it may concern.:

Beit known that I, DANIEL M. HARMAN, of Baltimore, Maryland, have invented a new and useful Improvement in the Manufacture of Cocoa and other similar Mats, of which the following is a full, clear, and exact description, reference being had to the accompanying drawings making a part of this specification, in which- Figure lrepresents a portion of a loom with a partially-woven mat thereon. Fig. 2 represents the filling-bar. Fig. 3 represents the under side ot' a mat.

My invention relates to making of door and other mats from cocoa and other similar materials; and it consists essentially in the devices which enable me to weave a mat on a loom, as herein described and claimed.

To enable others skilled in the art to make and use my invention, I will proceed to describe the exact manner in which I have carried it out.

In the drawings, A represents the foundation warp-threads secured in a loom, and B the tufting warp-threads, to be fed forward as required in the construction of the mat. C is the weft-thread to be introduced by a shuttle or any other desirable means. D D are filling-bars, which are introduced between the foundation-warp and the tufting-strands, whereby the latter are forced up and bent into the proper position and size to be out and form the tufts, the tui'ting-warp being raised by the shedding mechanism. These filling-bars are laid iat on the foundationwarp and below the tufting-strands, when, by a second movement of the shedding-treadle the tufting-strands are carried down over the lling-bars and below the foundation-warp, and the weft is then passed through the shed thus formed. As the reed swings forward to press up the weft, the lay strikes the bent arm ol of the filling-bar l), and turns it up upon one edge, thus forcing up the tuftingstrands into loops and securing them in position at the same time that the weft is driven tightly home. By another movement of the shedding-treadle the tufting-strands are again raised above the foundation-warp, and after the loops are cut the filling-bar is withdrawn and advanced for another operation. This is continued until the mat is of any desired length. In Fig. l the filling-bar is seen in its two positions, and two bars may be used, being alternately inserted and withdrawn. The tufting-strands, like the foundation-warp, are arranged on a roller so as to be easily fed forward, and in order that the material may be the more readily bent or tufted I usually arrange a trough of water in some convenient positiony so that the strands be thoroughly wetted before reaching the lilling-bars. This in a great measure overcomes the brash unyieldin g character of the tufting material and enables me to make a compact fabric.

Having thus explained my invention, what I claim as new, and desire to secure by Letters Patent, is-

Theflat filling-bar D, provided with an arm, d, and adapted to be operated in such a manner as to raise the tufting-warps into loops, as and for the purpose set forth.
