LooM FOR CROSS-WEAVING.

SPECIFICATION forming part of Letters Patent No. 352,258, dated November 9, 1886.

Application filed March 9; 1886. Serial No. 194,709. No model.)

To all whom it may concern:

Be it known that we, GEORGE OLDHAM and WILLIAM DIXON, both of Frankford, Philadelphia, in the county of Philadelphia and State of Pennsylvania, have invented a new and useful Improvement in Looms for Cross- Weaving, of which the following is a full, clear, and exact description.

Our invention relates to looms for weaving warp into filling-threads for making chenille, rugs, mosquito-netting, or any other crosswoven fabric; and the invention consists, principally, of means for giving the heddles lateral horizontal movement for crossing the warp-threads between the strands of filling.

The invention also consists of the special construction of the harness or plates that carry the warp-threads;and the invention finally consists of the construction, arrangement, and combination of parts, all as hereinafter described and claimed. 7

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a front elevation of a simple form of our improvement formaking narrow fabric with two sets of harness-plates, Without warp-beam, lay, or shuttle movement. Fig. 2 is a transverse sectional elevation of the same, taken on the linear w of Fig. 1. Fig. 3 is a sectional plan view taken on the line 3/ y of Fig. 1. Fig. 4.. is a similar view taken on the line 2 z of Fig. 1. Fig. 5 is an venlarged perspective view of two of the harnessplates and warp-threads passing through the eyes of the same. Fig. 6 is an end view of the cam-shaft for laterally reciprocating the heddies.

The frame shown is composed of the two side pieces, a a, base 12, and top cross-piece, c, on the under surface of which latter are attached brackets for the roller (1, over which the cords or straps e 6 pass, to the ends of which cords or straps the heddles ff are attached. The heddles are guided at each end by staples g g, passing around the upright rods hit, and are adapted to be alternately reciprocated by the levers t z, pivoted at j to the base I), and connected to the heddles by the cords or connecting-rods his. The upright rods h h at each end of the heddles are connected together at their upperand lower ends by plates or cross-pieces H, and these plates or cross-pieces] l are centrally pivoted to the horizontal supports or arms m m, forming in this instance a part of the upright plates 12 n, secured to the inner surface of the side pieces, a a, of the main frame. In a cross-brace, 0, is jonrnaled the horizontal shaft 10, contiguous to one of the plates Z, which shaft is formed with opposite cams, 10 p at its ends, so that the shalt when revolved will cause the cams p p to act alternately against the ends of the plate Z and vibrate it, and through it and the rods-h h and theother plates, Z, reciprocatethe heddles ff laterally and. horizontally at the same time they are reciprocated vertically, which causes the harness-plates q q to cross the warp-threads r r over the filling-threads and to twist them together or cross them between the filling-threads. I

The cam-shaft p is revolved intermittently by the ratchet-wheel s, secured to one end of the shaft, and the pawl s, pivoted to the plate 8 which is pivoted at one end upon the shaft 10 near the ratchet-wheel s, and connected at its other end to the plate t, attached to the front heddle, so the up-and-down movement of the heddle vibrates the plates and causes the pawl to turn the shaft 1) at each upward movement of the heddle. The plate s is connected to the plate It, in this instance, by the pin it entering a slot, 11*, made in the plate t, to accommodate the lateral movement of the heddle.

The harness-plates q are made of thin pieces of metal, each formed with an eye, q, through it for the warpthread, and each beveled at its end near the eye, as shown at g to form an angle to bring the passing points as near together as possible, as shown in Fig. 5. The

eyes q are formed by making an orifice through the harness-plates and bending the stock on each side of the orifice in opposite directions, as shown at q, to permit the warp-thread to pass in a straight line through the eye, and so there will be little or no friction of the warp in the eyes.

Having thus fully described our invention,

' the heddles are loosely attached, the plates 1,

- trally to said supports, and the frame to which '1, that hold the said rods, the supports m for we claim as new and desire to secure by Letters Patent 1. Theheddlesf, the vertical rods h, to which in which the rods h are held, the supports m for the plates 1, the latter being pivoted centhe supports are attached, in combination with the cam-shaft p and means, substantially as described, intermediate of said cam-shaft and one of the heddles, for actuating the cam-shaft, substantially as set forth.

2. The heddlesf, the vertical rods h, on which they are placed. the centrally-pivoted plates the plates Z, and the main frame, to which the supports m are attached, in combination with l GEORGE OLDHAM. WILLIAM DIXON.
