SPECIFICATION forming part of Letters Patent No. 397,074, dated January 29, 1889.

Application filed February 20, 1888. Serial No. 264,653. (No model.)

To @ZZ whom it' may concern.'

Be it known that I, JOHN R. EITTON, a citizen of the United States, residing at Vorcester, in the countyof \Vorcester and State of Massachusetts, have invented certain new and useful Improvements in Looms; and I do hereby declare that the following is a full, clear, and exact description thereof, which, in connection with the drawings making a part of this specification, will enable others skilled in the art to which my invention belongs to make and use the same.

My invention relates to looms for weaving, and more particularly to an improved mechanism to be applied to' looms having two or more drop shuttle boxes, to prevent the iilling from the shuttles which are not in use being drawn into the cloth or becoming entangled with each other.

The object of my invention is to provide a simple and effective mechanism to be applied toloonis of ordinary construction for the purpose above stated, and I carry out my invention by arranging at the end of the lay a system of lilling-feelers adapted to raise and hold the different iillings above the raceway while the shuttles from the lower boxes are thrown back and forth, said f eelers being operated automatically to rise and fall, as the different shuttle-boxes are called, by cams and connecting mechanism operated by the ordinary shuttle-box motion of a loom, in the manner to be hereinafter fully described.

Referring to the drawings, Figure 1 is a side elevation of one end of the lay of a loom to which my invention is applied, some of the parts being shown broken away for a more clear illustration. Fig. 2 is a section taken at line af fc, Eig. 1, looking in the direction of arrow a, same figure', the shuttle-boxes and other parts bein g left oft' in this figure. Fig. 3 is an end view looking in the direction of arrow l), Fig. 1, the shuttle-box lifter-rod,the lifter-rod arm, and other parts being not shown for the sake ot' clearness.

In the accompanying drawings, 1 is a portion of the loom side; 2, the arch; 3, the lay; 4, the lay end casting; 5, a tier of four dropshuttle boxes; (i, the laysword connected at its lower end with the rocker-shaft 7 S, the

rocker-iron secured to thc end of the rocker- 'shaft '7; 9, the shuttle-box lifterrod supported at its lower end in the rocker-iron S, and provided with a coiled spring, 10, and carrying at its upper end the lifter-fork I1 extending down from the tier of shuttleboxes 5, all in the usual way.

The box-chain 12, secured at its lower end to the box-lifter rod 9, passes over a sheave, 13, supported on the lay end casting 4 and over another sheave, (not shown,) and forms a connection to the ordinary mechanism for automatically operating the shuttle-boxes, as fully illustrated and described in United States Patent No. 134,992, of January 21, 1873.

I will now describe my improved mechanism to prevent the iillings from being drawn into the cloth applied to the loom of ordinary construction shown in the drawings.

Bolted to the i'ront side of the lay 3, at the end thereof and just at the open end of the tier of shuttle-boxes 5, is a casting or stand, 14, extending above the lay, with its upper end, 14', turned inward at right angles and extending over the raceway a sufficient height above the same to allow of the shuttles, as they are thrown from the boxes, passing freely under the turned end 14. The end 14 may be made separate from and adjustably secured to the casting 14, if desired. From the lower part of the casting or stand 14 an arm, 142, extends down and under the lay 3 and furnishes a. bearing for a stud, 15, upon which are pivoted the inner ends of three levers, 16. The lower end of the arm 142 of the casting or stand 14 furnishes a bearing for one end of the cam-shaft 17, upon 'which is secured a cam, 18, having three camsurfaces adapted to operate the three levers 16 by means of projections 16', which extend down from the lower edge of said levers and rest upon the cam-surfaces- To the front end of the three levers 16 are pivoted the three vertical sliding parallel rods 19, which tit into grooves made in the inner face of the stand 14. The upper ends, 19 of the rods 19 are in this instance bent in at right angles and extend inwardly over the raceway and under the turned-down end 14 of the stand 14, forming the feelers to engage the iilling-threads. When the three turnediin ends liV-that is, the'l'eelel's Alol' the tillingihreads-are raised to their ll ighest positions, as sllowll in the drawings, by means of the eanl-sul.'faees on the ealn 1S, through the illtervention ot the levers 1G, they will press up against. the under suriaee ol' the elld ll of the stand il, or against a yielding surl'aee, 20, preferably secured tllel'eon, and extend a sui'ieient height above the raeeway, holding the lillng-threads up with them, to allow of a shuttle troni the lowest box passing i'reely undel' illem. lVhen the upper shutiiflellox is at the raeeway, the feelers lil are ill their lowest. position and extend illto grooves ill the raeewa'y to allow of the shutile l'roln the iop box passing freely over them.

'.lhe eanl-shat't l? is supported at its outer end ill a braehei; or arm, 2l, and has a pinion, 2;?, l'ast thereon. In thelowel.' end. ot' the braeket )l is suppori ed a stud, 2S, on whieh is a seiftolsgear, il, which meshes witll the pinion 22 to operate the ealn-shat't 17 and parts eonneeted therewith. To the outer end oi. the arln 25, secured to the hub of ille seei'or-geal.' 2-1, is pivoted the upper end of the rod 2U. The lowel' end of said rod 2G :is pivoiied upon a stud, 27, extending ont from the Collar 2e on the lower end of the box-litter rod il. It will be seen that whatever motion is eonnnunieated to the shuttle-box litter-rod i) and ille shuttle-boxes by the shuttle-box motion (not shown) will also be eonln'lunieai'ed to the l'od 2li, alld through arm 25, seetorgear 2l, pinion 22, shaft 17,(:am i8, levers l (i, and rods lil to the ifeelers l il', thus Causing said ieelers lil to operate to l'aise and hold the i i l] ing-thread s above the race way, aeeording` as the different slli'ltifle-boxes are called.

rlhe operation ot' the mechanism above deseribed, alld illustrzli'ed in the drawings, will be readily understood by those skilled in the art.

There will be one less tilling-leelerlfl than tllel'e are shuttle-boxes, and when the lowest box is at the raeeway ille three teelers 19 will be ill their highest [losiiioll, when the seeond lowest box is at the raeeway two feelers will be ill their highest position and one in its lowest, when the third box is at the raeeway f one of the ieelers will be ill its highest posi tioll alld two in their lowest position, and when the top box is at the raeeway the three l'eelers will be ill their lowest position. The oanl-suriaees on the eanl 18 tor operating, through the levers lo alld rods l il, the ii'eelers lil are so iliade that aeoording as eaeh box is ealled by ille box-lllotion ille teelers lil are operated to aet upon the il'lling-thremls from the other boxes.

It will be understood that the details ol' eonsii-rl'letion ot' ille several parts oi` lnynleellanisln may be val'ied sonlmvhat i'ronl what I have above desel'ibed, it desired.

Instead ot' having a sillgle eanl, la, with three ealn-suri'aees tor operating the three levers l il, three staflaraie ealns may be seeured upon the shalt l7.

llaving thus described my in vent-ion, what l elailn as new, alld desire io seeure by Lei ters Patent, is-

l.. The Combination, wiill the lay, the iilling iieelers at the elld oi? the raeeway, rods li), and levers 1U, for operating the feelers, ot a shalt earryin cam-surfaces tor operating said levers lij, and meehz'n'lisnl eonneeting Said shaft with the box-littel.' rod to cause the same to be operated therewith, and the box-litter rod, substalltially as sllowll and described.

The eonlbin ation, with the lay, the iilling feelel's lil, supported oni-he layat the end ot the raeeway, rods lil, eollneeted with said teelers, and levers iii, tol.' operating` said rods, ot' a shai't, lT, having eanl-surii'aees i8 thereon, a pinion, 22, sector-gear Q11-, arm 25, and rod 2h, iiornling a eonlleetion between said shaft 17 and the shuttle-box motion, alld said shuttlebox motion, substantially as shown and de seribed.
