EPPA H. RYON, OF WALTHAM, MASSACHUSETTS, ASSIGNOR TO CROMPTON 8a KN OWILES LOOM WORKS, A CORPORATION OF MASSACHUSETTS. I

WEFT-REPLENISHING LOO'M.

To all whom it may concern:

Be it known that I, EPPA H. RYON, a citizen of the United States, residing at Waltham, in the county of -Midc nesex and State of Massachusetts, have invented cercarry'a new group of tain new and useful Improvements in Weft- Replenishing Looms, of which the following is'a specification.

My invention relates to weft replenishing looms of the type shown and described in U S. Letters Patent, No. 939,326,'and No. 951,659, and more particularly to improvements in the weft replenishing, or transferring mechanism, combined with looms of the typ referred to. 2

In the weft replenishing looms above referred to, a magazine'of a rotary type is used, in which the bobbins or filling carriers are arranged in. groups. The dilferent groups contain filling carriers of different colors or characters, which correspond to the colors or characters of the filling on the bob.- bins in the shuttles used in the loom. In this instance my improvements are shown in connection with aloom havin four shuttles, and the magazine is moved positively, and in unison with the shifting shuttle boxes at the .opposite' end of the loom, at each change of position of the shuttle boxes, preparatory to supplying the active shuttle with a fresh bobbin or filling carrier, on. the substantial exhaustion of filling thereon. After a bobbin or fillin carrier hasbeen removed from one groug in the magazine, the: magazine is moved to bobbins or Lfilling 'carriers into operative osition.

The object ,of my invention is to improve upon the operating mechanism of the rotary magazine, by means of which the magazine is-moved'from onegroup of bobbins or filling carriers to the next group, which movement, through my improved mechanism, takes place only after a predetermined bobbin of each group has been removed from the magazine by-the transferrer, and does not take place onthe transfer of anyother bobbin of a group.

Myinvention consists in certain novel features of construction of my improvements as will be hereinafter fully described.

I have only shown in the drawing a detached portion of a weft replenishing loom of the type above referred to, with myimprovemcnts combined therewith, sufiicient Specification of Letters Patent. Application filed march 25, 1912. Serial No. 685,917.

Referring to the drawing:Figure 1 is an end view of a detached portion of a weft replenishing loom of the type referred to, with the rotary magazine shown in section, and my. improvements combined therewith, and, Fig. 2 corresponds to vFig. 1, but shows some of the parts shown in Fig. 1, in a different position; some of the parts shown in Fig. 1 are left off in this figure. a

In the accompanying drawing, 1, Fig. 1, frame, 2 is the lay, and 3 the stationary shuttle box, having a shuttle 4 therein, carrying-afilling' carrier .or bobbin 6, Fig. 1, is a stand rigidly secured to the. loom side 1. The stand 6 has the cylindrical portion 6, with a centrally located and hori-n zontal ly extending bolt 7, to loosely receive the sleeve hub 8 of an outer ring, not shown. for the tips of the bobbins 5.- The heads of the bobbins or filling carriers 5 are mounted in pockets 9 on the inner ring 9, which ring is rigidly connected with the outer ring by the transverse rods 10, in the usual way.

A worm gear 1 l is mounted in this in stance on the sleeve 8,-and meshes with and is driven' by aworm 12, secured on the upper end of a vertically extending shaft-13. The lower end of the shaft 13 extends loosely through a bracket or hearing 14, attached totheloom side'1,'s'ee Fig. 1. 4

The transferrer 15 has the downwardly extending arm 15,..which is adapted to be operated by a dagger or hunter-on the'lay,

not shown, or otherwise. 1A horizontally extending arm 16, see Fig. 1, pivotally mounted on a stud 1G, is adaptedto engage with its forked end two collars 17, see Fig.

:2, on the vertically extending shaft 13, to move said shaft up and down, according to the position of the shiftingshuttle boxes, not shown, onthe opposite end ofthe loom.

A rod head 18, Fig. 1, is pivotally con nected to the lever 16, and a rod 19 extends upwardly from said rod head 18. and through :1 lug 20 on a stand.20, secured to the loo1n sidc,.see Fig. 1.. A helically coiled expansion spring 21 encircles the rod 1%), and acts to more downwardly the lever 16. The upper end of the rod 19 has connected there'- to one end of a chain 2'2, which passes over a i guide sheave 23, mounted on the stand 20,

- "shaped portion 13 thereon, which moves lon- 'and'to ,a pattern mechanism, notshown, on -theoppos1te end of the loom.

- The vertically moving shaft113 has a square 'gitudinally in an elongated hubof the bevel pinion 24,- which pinion meshes with and is driven by thetoothed portion, not shown, of.

the bevel: gear .25,1wh ich'has its hub loosely mounted on a'stud 25. Thebevel gear 25 has four notches25 therein, in which is adapted to'extenda projec'tion'26 on a pawl 26, see ig. 2. The hub of the pawl 26 is, loosely mounted-on a stud-27, on a stand, not

. 'shown' The stud 27 has also mounted there:

on the hub 28' ofia downwardly extending latch or pawl 28, which has a projection 28'.

pawl-26, and acts to yieldingly hold either one of the pawls 26 and 28 in their lockingthereon; which is adapted toextend into 'atending projection 28 on the latch 28, and-- at its other end against ,a lug 26 on the position, as shown in Fig.2.

"." T-lie pawl 26 has a side extension 26 there din-which engages with the end'of a shield.

- 3.0,t(;i hold saidshield in its inoperative po- "s'itiof1. 'The hub of said shield 30 is loosely mounted onthe elongated hub of the bevel gear 25. Extending downwardly from the hub of the shield 30 is an arm 30, which carries at its. 'end \30, a spring actuated- '-plunger 31, which extendso'ut from its cy- .ljiulrical holder 30 to engage the ratchet portion on the bevel gear 25, to move said ear, through the movement of the rod connected with the arm 30, one-fourth -ofsits revolution, when the awl 26 is raised,

to'frevol've the'upright slPa 1 8, and toturn the magazine from one group of bobbins to another group. All ofthe above mentioned parts may be of the usualand well known construction, and as shown and described in U. S. Letters Patent, No. 939,326, andNo. 951,659, above referred 'to.,

I will now describe my improvements, which consist of means to raise the hold fast pawl 26, .at the time when the'vertically moving shaft 13' is in its upper position, which may be when the upper box of the shifting shuttle boxes is on a -level with the race-way of the lay. 5

The vertically moving;rod- 13'has adjustably secured thereon a. collar;- 32, by a set screw 32. The collar "32 "is provided with a circular disk 32", which is adapted, on the upward movement of the rod or shaft 13, to engage the end of a lever 33.;The lever 33 is pivotally mounted on astud 34, at the npperforked end 35 of a fvertica'lly extend- .1. shield 3.0,,to allow said shield 30- to be operside 1,.see Fig, 1.

1.2 The lower end of the bolt 35 has an eye:

35?, which has connected thereto the upper end of a chain 37.- The lower end of the ja bracl'retor bearing 36, secured to the loom chain 37 isconnected to the pawl 26. A sec-' From the above description in connection with the drawing, the, operation of my im p ovell'lents be readily those skilled in the art, and briefly is as follows :On the indication of the substantialexhaustion of filling on a bobbin in the active shuttle, the transferr'er arm 15 is operated in the usual way, to transfer a bobbin 5 from the magazine into the active .ShllttlB 4, and as the vertically moving rod 13, according-to the position of the shifting shuttle boxes, has been moved to its highest position, as shown, in Fig. 1, the lever 33 will engage with its end the circular disk 7 32 on the c'ollar32, and through the operation of the transferrerarm l5, and intermediate connections to the lever 33, the

pivot point 34 of said lever 33 is raised, and also the pawl 26. is raised, as shown in Fig. The,.pawl 26 is disengaged from the atedthrough the rod 30" connectedjto a team lever, not shown, and through the spring actuated plunger 31 engaging a ratchet portion 25 on the bevel gear 25, the

bevel gear 25 is moved, and through its rotation, turns the pinion 24, and also the upright shaft 13, and as the worm 12.0n said shaft 13 is in mesh with the worm gear 11 of the magazine, the magazine will be rotated one-eighth of its circumference, to carry a new group of bobbins or filling carriers 5 under the transferrer. arm 15,- after the transfer of a bobbin.

' On thetransfer of another bobbin in the same group, as shown in Fig. 2, the circular disk 32" on the uprightshaft 13, hasnot been moved high enough to engage and move the end of the lever 33, and the transferrer arm 15 will, through its connection to said lever 33, rock said lever, without raising its pivot point 34, see Fig. 2, thus leaving the pawl 26 at rest, to hold the shield 30 in its inoperative position, and not move the magazine to another group of bobbins.

It'will be .understood that the' details of construction of my improvement-s may be varied if desired, and=that the magazine may be moved to another group of bobbins, at the lowest,position of the vertically moving rod 13, instead of at the highest position. Having thusdescribed my invention, what I claim as new anddesire to secure by Let ters Patent is 1. In a Weftreplenishing loom, a movable magazine, having bobbins or filling carriers of different color or character arranged in groups, a transferrer, and means to move the magazine to bring a fresh group of bobbins under thetransferrer only on the transfer of a predetermined bobbin of a group into the active shuttle. i

2. In a Weft replenishing 100111, a movable magazine, having bobbins 0r filling carriers of different color or character arranged in groups, a transferrer, and means to move the magazine to bring a fresh group of bob bins under the t-ransferrer only on the transfer of'a predetermined bobbin of a group into the active shuttle, and eoni'iectiens iii-- terinediate said transferrer and said means 3, In a Weir replenishing loom, a movable magazine, having bobbins or filling carriers of diiierent color or character arranged in groups, mechanism to more said magazine to bring fresh group of filling carriers in position raider tie tra-nsferrer and said transife 1'61, to cause an one of the filling carriof a group to be transferred into the active shuttle at the proper time, means to cause the op" tion of said mechanism, said means operating on the transfer of one or more of the predetermined bobbins of a group, and not operative on the transfer of the other bobbins of a group.
