W'EFT-REPLENISHING LOOM.

To all whom it may concern:

.Be it known that I, Framers E.- Asrrron, a citizen of the United States, residing at Exeter, in, the county of Rockingham and State of New Hampshire, have invented certaln new and useful Improvements in Weftlteplenishing Looms, of which the following 1s a spec1fication.

My invention relates to weft replenishing looms, and more particularly to the magazine'of a weft rgplenishing loom for holding the bobbins or lin carriers.

Magazines for we 't replenishing looms, as ordinarily made, are of the stationary type, or the movable type. Magazines of t e movable type ordinarily have a rotary motion in the arc of a circle, the axis of which is in a horizontal plane.

The object of my invention is to improve upon the construction of rotary magazines, and more articularly to provide a rotary ma azine "or two or more sets of bobbins or 'lling carriers, which has a rotary movement in the arc of a circle, the axis of which is in a vertical plane, and the bobbins are moved in a horizontal plane, at predeterand each set of bobbins carried over the shuttle at the stationary end of the loom, preparatory to supplying a fresh bobbin for the substantially exhausted bobbin in the running shuttle.

My invention consists in certain novel feamy improvementsa-s will be'hereinatter fully described. I have only shown in the drawings a detached portion of a weft replenishing loom, and particularly the magazine portion of the loom, embodying my nnprovements, sufficient to enable those skilled in the art to un derstand the construction and operation thereof.

Referring to the drawings :--Figure 1 is a ortion of the right hand end of a weft replenishing loom, and my improved magazine combined therewith; the magazine is shown in section, on

on an enlarged scale, the front view for the tip of the bobbins, holder detached, looking in d, Fig. 6 corresponds to Fig. 1, but shows a modified construction of the magazine, with the trans ferrer arm' located within the central part of the magazine.

see Fig. 2, when through-arm 9, link 9, and arm 10 connected with the filling detectin ractical or substantia ing on the bobbin in the running shuttle, the hunter 7 is raised into the path of the dagger 6, to operate the transferrer arm 8, in the usual and well known way.

I will now describe my improvements in the revolving magazine.

A stand 11 is secured to the loom side 1, and to the arch 2, and has in this instance fastened thereon a bracket or stand 12, on which is a boss .12, in which is secured the upper end of a vertically extending rod 13. Loosely mounted on the rod 13, and held thereon by a nut 14, is a vertically extending sleeve 15.

in this which extend out therefrom, and to the ends lly extendof said arms are secured vertica ing compartments 16', having guide-ways 16 for thebutts, and 16" forthe tips of the bobbins 17. Combined with the gnide-ways 16' for the butts of the bobbins, near the lower discharging end thereof, is a, movable bobbin holder or support 19, shown on an enlarged scale in Figs. 3 and 4, having a hub 19, which is pivotally mounted on a stud 20 secured to a boss 20 The inner end of the support 19 carries in this instance two outward 21, see Figs. 8, length'to supp and 4-, which are of sufiicient art a bobbin on the compartments 16.

if the bobbins in a compartment to retain all I during thenormal operat on of in position, the loom.

An arm 19" extends outwardly from the hub 19 and is adapted to be engaged by the .transferrer arm 10 upon its upward move.- ment, to rock said arm 19", against the ac- 5 tion of a torsion s ring 22 encircling the stud 20 andsecure .to it at one end, and engaging the arm 19 at its other end,- to

release the lowest bobbing and allow it to.

drop 'to' the dischar en The n er pin 21 will be moved position to ii ld the next bobbin, in its descent by gravity in the compartment, as'shown in Fig. 3, until the transferrer arm moves downwardl to transfer the bobbin at the lower end 0 the. compartment. The lowest bobbin in a series, which is, dropped to the discharging end,- rests upon extensions 23 on two vertically extending levers 23, which are pivotally mounted on studs 24 on the enlarged head 25'- on the vertically moving rod 25. The rod 25 is suitably guided m a ide-way 1 16' on the inner part of the gui e way 16 for the butt of the bobbin and is provided with a collar 25". A helically coiled expansion spring 26 encircles the rod 25, and engages at one end the collar 25",-and at its other end the lower end of the guide-way 16" in the guide-'way 16, and acts to move upwardly said rod 25 and the levers 23 thereon. The upwardly extending arms of the levers 23 are rounded, at 23", and engage the. enlarged portion 16 on the guide-way 16' in the normal operation of the loom, tohold the lower ends of the supports 23 in their closed position to supporta bobbin 17, as

shown in Fi 3. 1 The en agement of the transferrer 8 with the b0 bin, as shown in Fig. 4, will move down thesupports 23 carlied on the vertically moving rod 25, against ends 23 on the supports 23 pass on to the reduced end portion on.the part 16' to allow the supports 23 to move apart at their lower ends, ,to release the bobbin, as shown in Fig. 4. a

The devices for holding the tips of the bobbin, are the'same as the devices for holding the butts of the bobbins, above described. I I p The holder for the .ends of the filling threads from the bobbins, in this instance consists of u wardly extending wires, suitably attache to each compartment 16, as

shown in Fig. 5 extending in asubstantially vertical direction. One wire 27 is preferably covered with felt or other friction material, and the other wire 28 is attached'to' the first mentioned wire, leaving a space. between them to receive and hold the filling threads, preferably in bunches, see Fig. 1, .which Work downwardly, as the bobbins drop into their compartments. If one of the compartments in t e magazine is emptied,

the operator turns the magazine by hand to the action of the spring 26, until the rounded the next compartment, and to hold the ma gazine in position, while the loom is inoperation, I provide in this instance a pivotal lever 29, see Fig. 2, which carries a roll 30, which enters a recess 31' in a disk 31 secured to the sleeve 15; A helically coiled contraction spring32 is attached at one end to said lever 29, and at its other end to the stand 12, and acts to yieldingly hold the roll 30 in engagement with the recess 31' in the rer arm 10 has its hub pivotally mounted on- V stud 35, carried on the downwardly extendin arms 34 onthe bracket 34.

Iy improved rotary magazine, as Shown in the drawings, maybe turned by the operator to bring each set of bobbins over theshuttle at the magazine end of the loom, in

whichfca'se all of the bobbins would preferably have filling thereon of the same color.

In case it was desired to use bobbins having different colored filling thereon, then the magazine could be connected with the shifting shuttle boxes at the other end of the loom, to be. operated automatically in the usual way-by. the shifting of the shuttle boxes, or could be connected with a supplemental patternv surface, to be'moved at redeterminedintervals by said pattern sur ace, as will be well understood by those skilled .in the art.

It will be understood that the ,details ofconstruction of my Having thus described my invention, what I I claim as new and (lGSlIGf iO secure bye-Letlers Patent 1s:- p
