LOOK FOR WEAVING WIRE-CLOTH.

Specification of Letters Eatent.

To 0/! whom it may concern Be it known that l, Cannon L. Horn, a citizen of the United States, residing at York. county of York, and State of Pennsvlvania, have invented certain new and useful improvements in Looms for Weav ing lVire-(lothg and I do hereby declare the following to be a fulLwlear, and exact. description of the same, reference being had to the accompanying drawings, forming a part of this specification, and to the figures and letters of reference marked thereon.

This invention relates to looms primarily intended for weaving wire cloth, the objects of the invention being to provide a means whereby a plurality of-narrow widths of cloth may be simultaneously woven in a single loomwith an expenditure of power and time no greater than heretofore consumed in weaving a single width.

A further object of the invention is to simplify the construction and arrangement of the parts whereby the operation of the machine is improved and the necessity for imparting a variable movement to the shuttle carriers is obviated.

The invention consists in certain novel details of construction and combinations and arrangements of parts. all as will be now described and pointed out particularly in the appended claims.

in the accompanying drawingsl igure 1 is a front elevation of a wire bloth weaving loom, with portions broken away, and omitted in order to illustrate the present inven tion more clearly. Fig. 2 is a section in a vertical planefrom front to rear through a portion of the machine. Fig. 3 is an elevation of one end of the lathe or lay frame with parts in section and broken away. Fig. 4.- is a detail perspective view of the shuttle carrier :atch controller. Fig. 5 is an elevation partly in section of the shuttle catch operating cams and parts associated therewith. Fig. (5 is a sectional plan of the central portion of the lathe frame showin the shuttle catches. Fig. 7 is a longitudinal section through one of the shuttle carriers.

Similar letters of reference in the various figures indicate the same parts.

The present invention is illustrated in connwtion with a type of wire cloth weaving loom which is now in extensiv'euse and Well known. unnecessary to illustrate more than time For reason it is deemedadditional parts woulo.

parts of the loom which are directly associated with the mechanism forming the present invention, especially as illustration only tend to cont the drawings. v

In said drawings the reference letter A indicates the frame of an ordinary wire cloth weaving loom, the cloth beam being located the side of the machine facing the observer in Fig. 1, and at the left handside of the machine as illustrated in Fig. 2. B indicates the harness comprising the usual pedals and ope 'ating mechanism such as the levers B adapted to be depressed by cams (dotted lines, Fig. 3) on the shaft G. The lathe or swinging frame-is indicated'by the letter D and is adapted'to be swung or oscillated by the crank arms D mounted on a shaft D, said shaft D and the shaft- C being connected by 2 to 1 gearing D The reeds (not shown) are mounted in the transversely extending portion (Z of the lathe D and at the ends of said transversely extending portion Z slide ways or bearings d are provided for shuttle carriers or rods E. These shuttle carriers or rods are. recipro fated longitudinally by a central oscillator F connected with the outer ends of the carriers E by crank arms f and rods or links f, suitable springs f being in terposed in the connections, as is usual in this class of machine. The oscillator F is journaled on the lathe frames so as to swing therewith and its operating or oscillating mechanism comprises flexible connections F, rock shafts F (Fig. 1), flexible connections and links F and crank arms F, shown in dotted lines in Fig. 2 as projecting from the ends of the shaft C. The construction and operation of all these parts being well known no further description is needed.

The inclines Q. Figs. 2 and 4', are preterahly formed by the under faces of a head. on a block Q adjustahly moun ed on a slid inn rod Q The rod Q? slides in bearing-s held at one end 01'? the rod hy the fixed sheit and by the frame A at the opposite end 'z'l spring: serves to force the rod inwa dly or toward the rear and the rear end o rod is provided with or nnthtriction roller 1 adapted to cooperate with an adjustable cam ll mmintcd on the shaft (1 Cor (we ienl'ly the cams l: and R lllll he ad nst ably mounted on opposite sides a. i ll on said shal-"t and said cams are so positioned with relation to each other nor end of the rod or slide in engga ment with the cam ll, with the result t the slmttles are released fror'i the ccntr" fixed holder at the same time that they a ci'igag'ed by the latches in the carriers. 'lhe lest mentioned latches are released by the cams (3 only when the bell crank lovers t are not moved to draw the cams inwardly.

To retain the catches in the central holders released iroin' the shuttles during the initial forward movement. of the lathe the cam preferably made with an inclined have automatically engaged the catches in crank lever His caused to follow the movement oat? the. lathe for a short distance, thus givingthc carriers ample time to withdraw the shuttle; from'the holders. The cams O are held in inoperative position a sutticient length of time to allow the shuttle carriers to retreat or move outwardly beyond a osition where it would be possible for the bell c'ank levers N to engage said cams, the period during which they are held being determined by the length of the cam R.

By connecting shafts D and (l by 2 to 1 gearing, it will be seen that the lathe caused to make two oscillations during, each revolution of the shaft (7 and the shuttle carriers are reciprocated in and out during each movement of the lathe. During one movement or excursion of the shuttle carrier the bell crank lever H or movable release stop for the shuttle holder catches is out of operative position and the incline Q also out of its operative position so that the cams O are in position to engage the bell crank levers N to thereby releasethc shuttles from the carriers. This release 00 curs at the moment when the said shuttles the holder;

From the tioregoing, it will be readily understood that during one excursion of the lathe the shuttles are held in the central holders and during the next excurison of the lathe the shuttles are held in the carriers and during each excursion or at such period when the warp threads have been properly decussated the shuttles are transferred from the holder to the carrier or from the carrier to the holder and carried through the shed.

in the particular embodiment of the invention illustrated it will be noted that the shuttle carrier catch release cams are normally held in position to release the carrier catches, but are moved out of their operative position by the cam R on the drive shaft, but the catches ll of the shuttle holders will normally engage the shuttle and retain the same, unless the release stop or hell. crank lever H is advanced to movethem out .of operative position. Through the mechanism described, the two sets of catches are caused to alternate in action; that is to say, the holder catches release the shuttles wlnn the carrier catches engage the same and the carrier catches release the shuttles when the holder catches engage the same,

"thereby etfectinc a positive transfer of the the carriers, and shuttle catches in the carriers and holders, respectively, of releasing devices for said catches embodying cams timed to move into operative position durinn alternate excursions of the lathe, and connections controlled by said came for conmum;- the releasee'of the carrier and holder catches alternateiy.
