To @ZZ whom t 'may concern:

Be it known that I, ALBERT A. GORDON, Jn., a citizenof the United States, residing at Worcester, in the county of Worcester and State of Massachusetts, have inventedL a new and useful Veft-Replenishin'g Loom, of which the following is a specification.

This inventionrelat'es to 'a weft replenishing loom of the so-called terrytype in which a looped uncut pile is' formed by.

varying the forward positionofthe reed as different picks" of weft or filling are beaten'into the fabric.

More specifically,'l my invention relates to a loom of this typein which thereed is fixed in the lay and the forwardv position ofthe entireassembly of lay and reed is variedV on different beats Vof the lay.y

It is the Vobject of myinvention toprovide a weft replenishing mechanism for a loom of this type so mounted and'actuated that it' will always maintain its operative relation in respect tol the layy and' to 'the shuttle`and shuttle boxes thereon. i

For the attainment of this object, my improved magazine is movably `mounted on. the loom frame andV ris vso connected with the terry motionthat the position of the 1 magazine is changed to correspond to the forward or rearward adjustment of the lo# cus of the lay movement.

In the 'preferred form of my invention not only the magazinev but certain other A parts of the weft replenishing mechanism such. as the weft detector l'and the thread holder are also mounted to move as a unit with the magazine as the latter is vaiably positioned.

My invention further relates to arrangements and combinations of'parts which will beherelnafter described and more particularly pointed out in the appended claims.

A. preferred form of' my invention is shown in the drawings, in which- Fig. 1 isa sideelevation'of parts of a loom embodying my improvements;

Fig. 2 is a detail 4sectional view taken along the line 2-2'in.Fig. 4'1;

Fig. 3 is a front elevation of my improved magazine and the supports therefor;

Fig. 4 is a detail rear elevation looking in the direction of the arrow 4 in Fig. 1; and

Fig. 5 is a detail side elevation looking in the direction of the arrow 5 in Fig. 3.

Referring to the drawings, I have shown parts of a loom which are in general of the usual terry type comprising a loom frame 10, an'arfoh 11, and a lay 12 mounted on swords 13 which swing about fixed pivots, not shown. The lay is Imoved forward and rearwar'din the usual .manner by conn'ectin pins 15in a crankshaft 16.l

The bearing :for the 'shaft 16 are eccentri-y callyfpositioiied fin`y cylindrical bearing blocks 17 rotatablymou-nted.` in 4journal boxes 18. n arm' 19 is fixed to each bearing block 17 and is connected by 'a 'link 20 to an arm 21 fixed on a cross shaft 22. An actuatingiarm 23 also fast: on the'shaft v22 is 'connected'by g 'rods 14 actuated fromv "crank a tlink 24 to -a'stud 25 in a lever 26. *The lever "26 is pivotedat 27 to across girt 28 and is periodically moved downwardby engagementf'w'ith'a `roller 29 on an arm 30.

" The arinBO. rotates with la gear -31 driven by-'a pinion 32 on the usual bottom or cam shaft 33 of the loom.l `As shown in 'the drawings, the gear 31 and pinion 32` are inthe size relation o'f threey to two. yAs the bottom shaft ,3-3 rotates onceJ for every two beats of the lay, the lever 26 will v.be depressed once for 'everythree'beatsof the `'It will-be. understood, however, that. the gearing. ratio. maybeA varied to produce` a movement of the lever 26l once yinany desired number of beats of the lay. The-parts are shown in Fgl with therleverf' depressed and thel'ay. in its extreme forward position,` the parts assuming this position o1revery'thrd-beatfof ,the lay.

y"The parts .thus far described, are of the usual type and-formino part of my present 5 nventQm which relates particularly tothe, weft replenishing mechanism and to the provision 'of means by which it may be maintained in' operative' relation to the .n lay,

whether the. samey is forwardly or rearwardly positioned. f

f A weft carrier 'magazine y85 of the usual type for'multi-color ,work is shown in the '.f

drawings, the magazine eomprisinga maga'- zine frame 36, an outerbobbin support 37," a thread holder 38, a transferrer 39 and other usual parts associated therewith. A link 4) (Fig. l) is connected to a bell crank 41 pivoted at 42 on the magazine frame and connecting the bobbin releasing devices with the usual drop box mechanism. not shown.`

For a detailed description of the magazine and its connection to the drop box mechanism, reference is made to the prior patent to Wyman No. 970,591 issued September 20, 1910.

The magazine frame 36 is in part supported upon a slide 43 (Fig. 3) mounted in a block or guide-way 44 bolted to the front of the loom frame lO. The slide 43 is preferably lofthe dove-tailed section shown in Fig. 3

and suitable provision is made for maintaining a close sliding t between the parts. A second slide 45 (Figs. 1 and 2) is mounted to slide in a guide-way or block 46 irmly secured to the loom arch 11.

An actuating lever 48 (Figs. 3 and 5) is mounted on a fixed pivot 49 and the forked upper end of the lever 48 engages the elongated end of the shaft or stud 50 upon which the transferrer 39 is pivoted. The lever 48 is connected by an adjustable link 51 to an arm 52 secured to one of the cylindrical bearing blocks 1T which support the crankshaft 16.

Through these connections, the lever 48 will be swung on its pivot 49 whenever the bearing of the crankshaft 16 is moved forward or rearward, and a corresponding forward or rearward movement of the magazine 35 will occur. The magazine 35 is thus always positioned in co-operative relation with the shuttle S in the shuttle boX 53 (Fig. l), the magazine moving-forward or rearward whenever the locus of movement of the lay is shifted forward or rearward. A weft carrier transfer may thus occur on any beat of the lay provided the desired shuttle S is in the box 53.

I have also-provided weft detecting mechanism of a usualv type, mounted upon' a bracket 54 secured by bolts 55 to the magazine frame and movable forward and rearward therewith. The weft detecting member 56 (Fig. 1)- is thus maintained in operative relation with the shuttle in either the forward or rearward adjustment of the lay.

I have thus provided simple and reliable mechanism for maintaining operative relations between the lay and thevmagazine and parts associated therewith, regardless of changes in the locus of movement of the lay, so that weft carrier transfer will not be subject to interference from such changes in adjustment.

In the specification and claims the term locus of movement is used to indicate the limits of movement of the lay when the lay is oscillated and the bearings remain in some fixed position. When the bearings are tions can be made therein by those skilled in the art within the spirit and scope of my invention as set forth in the claims, and I do not wish to be otherwise limited to the details herein disclosed. but what I claim is 1. In a loom, a lay, means `to shift the locus of movement of said lay forward and rearward, a loom frame, a weft replenishing mechanism movably Lmounted thereon, and means to move said mechanism forward and rearward to maintain the same in operative relation to said lay.

2. In a loom, a lay, meansv to shift the loc-us of movement of said lay forward and rearward, a loom frame, a weft replenishinff mechanism mounted to slide thereon, an means to slide said mechanism forwarder rearward as the locus of movement of the lay is shifted.

3.v In a loom, a lay, means to shift the locus of movement of said lay, a loom frame, a weft replenishing mechanism movably mounted thereon, and connections from said magazine to said lay-shifting means by which said magazine may be shifted forward or rearward to correspond with a change in the locus of movement of the lay.

y4. In a loom, a lay, means to shift the locus of movement of said lay forward or rearward, a weft .detecting device, and means to maintain said detecting device in operative relation to said lay in all positions ofthe locus of movement thereof.

5. In a loom, a lay, means to shift the locus of ymovement of said lay forward or rearward, a weft carrier magazine, a thread end holder thereon, and means to maintain said thread end holder in operative position for all changes in lay movement.

6. In a loom, a lay, a crankshaft connect ed thereto, bearings for said crankshaft, 'automatie means to shift said bearings forward and rearward at predetermined intervals, ya weft carrier magazine, and connec-v tions between said bearings and said maga- ALBERT sonnen, JR.
