UNITED STATES PATENT OFFICE JOSEPH CLAYTON, OF DRAOUT, MASSACHUSETTS.
IMPROVEMENT IN LOOM SELVAGE-GUARDS.
Specification forming part of Letters Patent No. 148,036, dated March 3, 1874; application tiled May 31, 1873.
To all whom 'it may concern:
Be it known that I, J osEPH CLAYTON, of Dracut, in the county of Middlesex and State of Massachusetts, have invented a new and Improved Selvage Guard or Regulator, to be used on looms in weaving textile fabric, of which the following is a full, clear, and exact description, reference bein g had to the accompanying drawings making part of this speciiication, in which- Figure l represents an inner side, Fig. 2 a plan or top view, and Fig. 3 an end elevation, being the forward end, of a common loom-temple with my improvements thereunto applied for practice.
This invention relates to certain new and useful improvements in selvage guards or regulators, to be used ou looms lin weaving textile fabric, and combined with and operated by the temple, as hereinafter described. This invention has for its object, first, the formation of a better, more perfect and even selvage on woven fabric, a selvage that shall be of the same thickness, tension, and elasticity, and, if desired, the same texture of the fabric, and which shall not cockie or turn over as the fabric is wound upon the cloth roll or beam; second, my invention has for its object to protect the ends or outer dents of the reed by holding the selvage-threads out when the lay and reed advance to beat up the filling, and also when the reed and lay recede third, my invention has for its object to protect the selvage-guard from injury from stopping shuttles, as hereinafter described.
When myimproved selvage-regulator is com bined with the loom-temple, as shown, and operated by or simultaneously with the temple, I generally form the arm G, about as shown in the drawings, with a center hub or bearing, j', which is fitted to and works on a stud, c4, on'the end of a slotted plate, d2, adjustably secured to a second slotted plate, d3, adjustably fastened to the yielding bar B of the temple. l then apply thevroll I) to the stationary side of the temple, as shown, and form the rear end of the arm G with a tail or guide, g1, and a cam or incline, m, to Work beneath the roll b, and depress the rear end of the arm, and raise its forward end and the points g from their place between the selvagethreads, which is ing to any part of the burr or jaw of the temple.
When the lay recedes, after beating up each filling-thread, the temple moves forward, as
usual, and the connected arm follows it. At
such times the forward end-of the arm and points g are depressed, to bring the latter between the selvage-threads, by means of acoiled spring, n, one end of which is fastened to the arm, and the other end to the stud-plate d?, the spring n encircling the stud c4.
The roll b is of suicient length to allow of any desired adjustment of the arm G transversely with the temple. The plate d carries a fender, g2, which projects downward, forward of the feed end of the temple, and outward a little beyond the points g, or the heads in which they are set. The object of lthis fender is to prevent injury to the points by shuttles, which sometimes stop in the web, opposite the temples, just as the lay advances to beat up the filling. The shuttle being struck by the reed would bend or break the points, and the fender saves them.
The object of the longitudinal adjustment of the arm is to carry the points farther from or nearer to the feed end of the temple, and thereby to catch and hold the lling at any desired distance from the fabric last formed, so as to cause a greater or less degree of slackness of the filling against or around the outer selvage threads, the points 1or prongs g passing between such selvage-threads in time to receive the strain of the filling caused by the velocity of the shuttle at each beat ofthe lay.
For the want of a selvage-regulator in ordinary weaving, I have found that the fabric is more or less affected by the tension of the filling for several inches inside of the selvage.
When the cloth is a little more forward tox'vard and at the selva-ge than in the middlethe temples, varying from two to eight inches,
according to the kind of fabric.
rlhe extra strain on the edges of the warp tends to make them longer, While the eXtra strain of the filling tends to make the fabric narrower than its natural Width, and this narrowing or drawing in of the selvage-threads causes them to cut and Wear the outer dents oi' the reed more rapidly than the middle dents are Worn.
The difficulties above enumerated are beyond the capacity of the temple to overcome, as it has nothing to prevent the illing being driven home at the instant its tension is greatest. By the use of my improved selvage guard or regulator all the labove-named difficulties are overcome; and, besides this, the outer dents of the reed, or those dents nearest the ends, will be protected by keeping the selvage-threads out, or. in line With the forming fabric, Which will shrink a little after passing the temples, and sufficiently to carry the edges clear of the upright parts of the sewage-regulator.
A Xed bar or incline may be substituted for the cam-operating roll b, and made to Work successfully by lubricating the cam.
'I claim as my inventionl. The arm Gr, constructed as described, with camion, guide g1, and prongs g, in .combination With the adjustable stud-plate d2, spring u, and slotted plate d3, and with the roll bland the temple, all arranged and operating in the manner and for the purpose specified.
2. The fender g2, in combination with the adjustable plate d3 and the'temple, and operating to protect the points g, asdescribed.
JOSEPH CLAYTON. Vitnesses:
JOHN E. CRANE, WILLIAM R. CRAFE.
