HORACE WYMAN, OF WORCESTER, MASSACHUSETTS, ASSIGNOR TO CROMITON & KNOWLES' LOOM WORKS, vA CORPORATION OF MASSACHUSETTS.

LOOM-FILLING-CARRIER MAGAZINE.

To aZZfwhom 'it may concern:

1 3e 1t`known` that I, HORACE WYMAN, a citizen of the United States, residing at v I-Vorcester, in the county of Worcester and Y lguidej ,way or compartment, and are retained therein by a device or mechanism at the lower end thereof, which is moved at the desired time, to'release the lowest' bobbin andfallow it to drop down to .the discharg ing end of the magazine, pre aratory to being transferred into the shtt e, and also acts to retain the bobbinswabove -thelowest bobbin, inthe compartment.

My invention particularly relates tothe device or mechanism for holding the bobbins intheir compartments in the .magazine, and for releasing the lowest bobbin, and for retaining the other bobbins in the compartment.

It has been found in practice that in the classof magazines referred to, that 'the head of the lowest bobbin, and the tip of said bobbin, are-notsimultaneously moved by the movable bobbin support or retainin device, and that the head of the bobbin an the vtip of the bobbindo not move down to the dis- -charging end of the v`magazine in proper.

alinement; the tip of threbobbin` is liable to move ahead of the head of the bobbin, and

`vice versa, so that when the bobbin reaches the discharging end of the-magazine, pre.- paratory to beingengaged by the transferrer and transferred into the shuttle, it is in an inclined position and will not properly enter the shuttleand will often arrest the movement vof the t-ransferrer and may` cause breakage. Y The object of my invention is torovide" a movable deviceor mechanism, for olding the bobbins in" their guide-ways or compartments, and for releasing the lowest bobbin and retaining the other bobbins, of improved construction, and which 4.will engage and hold the Ahead. of the bobbin, and also engage Specification of Letters Patent.

land hold the tip end of the bobbin, and when the device is operated to release the lowest bobbin, thehead and tip of the bobbin will be simultaneously moved, .and 4the bobbin will move down to the discharging end of the magazine in proper alinement, to extend under the transferrer' in proper position to be transferred in to the shuttle.

In my improvements, I preferably have a rocking support or holder, for the'lowest bobbin in the compartment, which'holder is pivotally mounted at each end to have a rocking movement, and the pivot supports are in axial alinement. Said support or holder preferably has two pins or extensions thereon for the head of the bobbin, and a separate support for the tip end of the bobbin, which also acts to engage thetip end of th'e bobbin next to the owest bobbin in the compartment, to retain it in position, when the lowest bobbin is released. Likewise one of the pins for the head of the bobbin engages the head of the bobbin next to the lowest bobbin to retain it in position, when the lowest bobbin is released.

' I havejonly shown in the drawin a detached part of a magazine of the c ass referred to, with my improvements combined therewith, suicient to enable those skilled inthe art .to understand `the construction and o yeration thereof..

Re erring to the drawing Figure l 1s an outside end view of the lower part of a magazine, having one guide-way or compartment, with my improvements combined therewith, and showing four bobbins or filling carriers. Fig. 2 is a section, on line 2, 2, Fig. l, looking in the direction vof arrow a, same figure. Fi 3 is a section, on line, 3, Fig. 1, looking 1n the direction of arrow a, `ig. 4 isan inner end view of the parts shown in Fig. 1, looking in the v'direction of arrow b, same figure. F ig. 5 vcorresponds to Fig. 2, but shows the bobbin head support in its opposite position. Fig. 6 corresponds to Fig. 3, but shows the oppo# site position of the bobbin tip support, and Fig. 7 is a perspective vView of the bobbin support, detached. y v In the accompanyingdrawing, 1 is the `inner end of a magazine, having in this instance a singleguide-.w'a for the heads 2 of the ,bins 2. .y 3v is the outer end of the magazine, having in this instance a single guide-way or comor compartment partment for the tips 2 of the bobbins 2. The inner end l and the outer end 3 of the magazine are preferably connected by transverse rods, not shown, in the ordinary way, and each has a discharging end 1 and 3', respectively, for the bobbins. The bobbins 2 are superposed and A.drop down by gravity in the magazine.

All of the above mentioned parts may be of the usual and well known construction.

I will now describe my improvements. Combined with the inner'end 1 of the magazine and the outer end 3, near the lower dischar ing end thereof, is a movable bobbin holder or support 4, which ispreferably made as shown in Fig. 7 The inner end of said support 4 in this instance has a hub 4, which is pivotally mounted.on a stud 5 secured to the inner end 1 of-themagazine,

and forming the axis or fulcrum of the inner end of the support 4. The inner end of the support 4 also carries a pin 6, which is.

connected to a rod or connector, not shown, through which a rocking movement is communicated to the support 4 in any usual way. The inner end of the support 4 also carries in this instance two outwardly extending pins or extensions 7, and 7 which are preferably of a length corresponding to the length of the head of the bobbin. The lowest pin 7 is adapted to extend under tbe lead of the lowest bobbin, as shown in Fig. 2, to retain the bobbins in position in the normal operation of the loom. The in 7 is adapted to extend under the bobbin above the lowest bobbin, as shown in Fig. 5, 'when the support 4 is moved orrocked to release the lowest bobbin. y

The bobbin support 4 extends across the magazine, as shown in Fig. l, in a position parallel to the lowest bobbin. The outer end of the support 4 is provided with a pivot or fulcrum pin 8, which is loosely mounted in a boss or bearing 9 on the inner edge of the outer end 3 of the magazine. The pivot or fulcrum pin 8 is in horizontal alinement with the pivot or fulcrum pin 5. In this instance the fulcru'm in 8 is carried on the support 10 for the tlp ends of the bobbins. The support 10 is preferably made separate from the support 4, and consists of a plate, pref erably of the shape shown in Fig. 7, having an elongated curved opening 10 therein, through which extends a screw 11, which is screwed into a threaded hole in a lip or extension 4" on the support 4, and acts to vadjustably secure the support 10 in position on the-support 4.

The support 10 for the tip ends of the bobbins, extends in a Vplane 1n vertical aline: ment with the tip ends of the bobbins, as shown in Fig. 1, and is preferably of curved shape on its engaging edge 10, as shown; the lower part of said ed e is adapted toextend under the tip end o the lowest .bobbin,

as shown in Fig. 3, when the loom is operating normally, and on the movement or rocking of the support 4 to release the lowest bobbin, the upper end of the support 10 is moved under the bobbin next to the lowest bobbin to retain it in position, as shown in Fig. 6.

The operation of my improvedv bobbin support or holder will be readily understood by those skilled in the art; 'When the holder or support 4 is rocked to release the be readily appreciated by those skilled in the art; they are of simple construct-ion and can be readily applied to magazines for filling carriers, having one or more guide-ways or compartments, of usual construction. By means of my improvements the head and tip end of the lowest bobbin is supported independently, and the head and the tip end are simultaneously released to allow the lowest bobbin to drop down to the discharging end of thejmagazine, and the head and tip end of the bobbin next to the lowest bobbin are simultaneously engaged and retained in position, preparatory to the return movement of the bobbin support or holder, when all the bobbins move down by gravity in the magazine in the usual way. A

It will be understood that the details of construction of my improvements may be varied if desired.

I prefer to use two pins or extensions '7, and 7 for the heads of the bobbins, but if preferred a single support or plate similar to the support l0, may be used.

Having thus described my invention, what I claim as new and desire to secure by Letters -Patent is 1. In a magazine for a weft replenishing loom, having a guide-Way or compartment for the yheads of bobbins, and a guide-way or compartment for the tips of bobbins, al

tip in properv rocking support or holder for the lowest'- bln.
