GEORGE THOMAS GREEN, 0]? HAILSI-IAM, ENGLAND.

Application filed April 15, 1914.

To all whom it may concern Be it known that I, Gnonon THOMAS (hm-EN, gentleman, a subject of the King of Great Britain, residing at Jesmond Dene, Summerheath Road, Hailsham, in the county of Sussex, England, have invented new and useful Improvements in or Relating to Machines for the'M'anufacture of Mats and the like; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

The invention has reference to certain improvements in or relating to machines for the manufacture of mats and the like.

A machine constructed in accordance with this invention is adapted to manufacture mats with coco or coir yarn, New Zealand flax, hemp, aloe, jute, tow, sisal, and ramie.

The yarn is composed ofthree sections. One

of these sections which consists of the required number of hempen cords and may be termed the foundation warp is passed from the yarn beam through the machine in one continuous sheet. The two remaining sections of warp may be composed of jute and coir threads respectively or other suitable fiber the respective sections being wound on separate supplementary yarn beams or spools the jute and coir leaving the beams or spools in such a manner correlatively as to effect the intersection of the yarn as hereinafter explained. The shedding or interweaving of the two latter sections with the main hempen or foundation warp is effected by means of a series of needles fixed in a reciprocatory frame adapted to move vertically and be depressed by a suitable treadle actuated by pressure of the operatives foot, the needle frame when released being raised by means of springs or other elastic medium. In the upper part of each of the series of needles is formed a large eye and in the lower part thereof is a long narrow eye. The coco or coir passes through the large eyes and the jute through the elongated eyes. The shuttle when the needles are down passes under the foundation warp and over the coco and jute but when the needles are raised it passes over the warp threads and under the coco and jute. Then the frame containing the needles is raised the jute is at the bottom of the elongated eyes so leaving a clear space between the two sets of threads for the passage of a grooved rod.

Specification of Letters Patent.

Patented Feb. 29, 19MB.

Serial No. 832,000.

The shuttle is picked through the shed by hand and a shot of weft from the shuttle is beaten up by a suitable reed or batten which is adapted to oscillate by hand when beating up the'weft. After a few succeeding shots of weft are woven into the material the coir threads are out along the groove in the rod to form the usual tufts constituting the upper surface of the mat when the grooved rod is removed. The woven material 'is drawn forward through the machine by suitable taking up mechanism and when a mat length has been woven it is cut from the piece. Suitable let-off mechanism is also provided to regulate the tension on the yarn in the process of weaving.

In order that my invention may be fully understood I will now proceed to describe the same with reference to the accompanying drawings in which- Figure 1 is a diagrammatic view of a machine with my invention applied thereto. Fig. 2 is a front elevation of the needle frame. Fig. 3 is an enlarged view of a needle constructed in accordance with my invention.

In Fig. 1, a, b, and 0, is the yarn composed of the foundation, pile, and jute threads respectively which pass through the needles in the frame (Z which is reciprocated within the guides e by suitable treadle motion f and from thence to the usual heater 9 which beats up the weft, not shown, after each shot. The mat or the like h when completed is wound upon a suitable roller 71 by the take-up mechanism The needles shown in Figs. 2 and 3, are formed, in their upper part, with a large eye 76 and in their lower part with a long narrow eye Z. The coco, coir, or pile passes through the large eyes and the ute 0 through the elongated eyes.

What I do claim as my invention and desire to secure by Letters Patent is 1. In a machine as set forth; a shedder comprising a reciprocating heddle frame; a plurality of needles, each being provided with an eye, and having an elongated slot with one of its ends adjacent to and spaced from the eye; said needles being mounted in said heddle frame in alined parallelism, whereby three sets of warps or threads respectively pass through the needles, one of which warps being stationary and passing between the needles, the other two being movable, the eye and slot being so arranged and designed to respectively receive the movable warps or threads, which are crossed through the operation of the eye and slot; and means to reciprocate said heddle frame to cause the eye and slot to so operate, as to cross the movable warps with relation to the stationary warp in weaving mats.

2. In a machine as set forth; a shedder comprising a reciprocating heddle frame; a plurality of needles, each of which having a substantially central fiat portion, provided with an eye at one end, and having an elongated slot shorter than the fiat portion with one of its ends adjacent to and spaced from the eye; said needles being alined in parallelism and mounted in said heddle frame, whereby three sets of warps or threads respectively pass through the needles, one of which warps being stationary and passing between the needles, the eye and slot designed to respectively receive the other two warps, which are crossed through the operation of the eye and slot.

In testimony whereof I have signed my name to this specification in the presence of two subscribing witnesses.
