T 0 on whom 1' I? may concern:

Be it known that- I, HAMILTON LINDSAY, a citizen of the United Statesa-residing at Clevela1id,.in thec'ouiity of Cuyahoga and State of Ohio. have invented a certain new anduseful Improvement in Vire-Looms, of which the folljowing is a full, clear, and exact description; reference being had to the accompanying drawings;

The invention broadly relates to the class of loom's, and moreparticularly to those for weaving wire cloth, as set forth in my prior PatentsXo-= 73 1,1 12, granted June16, 1903,

andXo. 8 tet.8l8, granted February 19, 1907.

Moreparticularly, the invention relates to certain improvements upon the construction set forth in theabove mentioned patents, and has reference to the mechanism for'stretch ing the wire weft after it has been laid in the shed andibefore-ithas been followed up by the reed upon the batten.

The invention may be briefly summarized as consist ng 1n the construction and combinationof partshereinafter described, referencebeing had to the ,following description,

drawing and claims.

referring to the drawings, Figure 1 is a sideieleyatlon of the machine; Fig. 2 1s a "vertical cross slection; ,Fig. 3 is a front elevation brokenaway at. its center; Fig. 4 is a.

adjacent parts.'

perspective view of "the shuttle box and the This invention may be applied to any suitable construction of 100111, preferably the type 0f.1 l1t1hll1 illustrated in the patents referred'to, wherein- A- represents the frame provided with suitable bearings afor supporting the warp beam B, having suitable grooves for receiving the warp threads. On the forward part ofthe frame. is theguide roller C andthe cloth beam C for" guiding and winding up the cloth after it has been Woven. Suitable "gears and mechanism are provided between the warp beam. and the-cloth beam C for giving'ofi' the warp threads from the former and for winding up the finished cloth upon the-latter; This mechanism is covered'by thesaid prior Patent No. 731,112, and forms no part of this cas'e,"it being only necessary that there besuch a device in order. that there will be a tension upon the warp threads. and that the clot-h will bewound up "after it is finished E The heddle frames are represented at D and These heddles are moved up and down through the inst-ruinentality of the cams e and 6 upon the shaft E, by suitable connecting mechanism. The movementof the heddles causes the ranks X and X of the warp threads to cross each other and thus form the shed.

Pivote d to the upper part of the frame is the batten frame F, which carries the picker,

arms F and F lay G, and shuttle boxes H and H'. Suitable mechanism is provided "for imparting a strong and quick movement to the lower ends of'the picker staff so that when in turn each picker staff engages the shuttle, the same will be shot across the race to the opposite shuttle box. In the embodiment shown, this mechanism includes springs f and f", cables f levers f and cams e Carried by the lay G is the reed g secured in any well known manner, with the ranks X and -X of the warp threads passing therethrough. Secured in the lay, and preferably at the rear thereof, is a rock shafti'gfl provided with forwardly projecting arms 9 rigid with said shaft and carrying at their free ends the shuttle race 9 A spring 9 so f normally tends to hold the shuttle race in its lowermost positionthat is, out of engagement with the warps and the finished cloth. This shuttle race, however, is arranged to be moved into its uppermost position ,or under "the lower rank X of the'warp threads when the lower end of the batten is in its rearward position.

Secured to the batten F, at each end of the lay, are the shuttle boxes H, H. These boxes are of substantially the construction shown in the drawings, having a bottom.

plate 72., front plate h, and a rear plate 72?,- the front plated! and the rear plate b being provided with inwardly projecting lips or flanges 7L and b which serveto keep the picker block H? in the shuttle box. All of these parts are of ordinaryconstruction and are well known in the art.

A rock shaft K carried -by"the. shuttle boxes has an arm k at each end adapted, in v case the shuttle fails to enter the boxes, to swing to position to engage block-Z carried by trigger L and so release rod M which is then shot downward by spring m and caused. to rotate shaft N and shutoff the power. This shut-ofi' mechanism can be reset by means of the lever T.

The mechanism for creating a tension upon the weft or shoot, after it has been laid in the shed, consists of apair of rigid arms P and P arranged just above the entrance to each shuttle box and spaced a short distance apart. One of these arms I? is secured to the rear of the shuttle box at one end, passing across the entrance to the shuttle i'jiox with a straight portion 72' and down at the side and down in front, to a clip secured to the front of the shuttle box. The other arm extends out with a prong substantiallyparallel to the straight portion p- ,of the clip P, and is left free at its end so that the weft may be readily kicked thereffrom. Pivoted to a bracket 19 upon the lay of the batten is a lever arm p v which has a block loosely mounted upon the pin 72 secured in said bracket p, A spring 79 is arranged between the head of the pin and vthe block 7) for giving the lever arm anornial downward tendency. Upon the free end of the lever armp 'is secured a block 9' carrying a downwardly] projecting finger p which has a'turned end portion adapted, when raised, to pass between the straight portion pf and the prong P, but to normally rest in a recess h" in the projected bottom plate h of the shuttle box, whereby, as the shuttle is shotfrom one'box to the other, the

weft will be laid across the end portion of i said finger'in a position to be engaged thereby when raised. The means for raising these fingers consists, on the lefthand side ofthe machine, of a link 9 connected to a spring q secured to the end of a lever Q, loosely mounted upon a rock-shaft Q, and connected at-its opposite end to a long link 9 extending down and connectedto an operating lever 9 which-has a friction roller 9 for engagement one of thecams g and g. Theselevers are provided with openings at their forward ends which are engaged by standards 9" provided with adjusting blocks 'g'i to limit the upward movement ofsaid letiers. The ,pair of rigid arms P P, and the finger, 12?, together with its lever p and spring 39 is provided at each end of the lay, I and the mechanismfor operating the one at the left has been described; The mechanism ,fOr operating these; same parts at the other side. of the machine consists of an arm 9 keyed to the rock shaft Q and rocked by an ii -m q? connected by a link to'a lever simi to thele'ver q and operating in a like .manner; It will be seen from the mechajust described, that as the shuttle enters box, ,it leaves the weft wire lying across the fin 'er 7 just as the batten is about to move orward to follow up the weft and press it toward the finished fabric. At this particular time the cam g shifts the lever g and, through thetrain of connections just described, raises the lever arm 0 and its fin gel 12 whereby the weft is drawn slightly within the shed and up between the arms P and P. Means are provided for further stretching and. kicking off the weft from the end of the finger p and or the arm I, and

by a sleeve t loosely mounted upon a pin r and having a spring 7* between it ahd the pin, whereby the prong R is normally kept in its rearward position when the batten is also in its rearward position. Extending upward from the sleeve R is an arm 1' connected by a flexible connection 1? with the frame work A, whereby upon the forward movement of the batten the prong R moves forward and gives a further stretch to the weft and kicks it from the end of the arm P and from the end of the finger p Having described my invention.
