Application led November 27, 1911. Serial No. 662,537.

To all 'whom z't may concern.' y

Be it .known that I, EPPA H. RYoN, a

citizen of the United States, residing at.

Waltham, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in Weft- Replenishing Looms, of which the following is a specicat-ion.

My invention relates to weftreplenish'- ing looms ofl the type shown and described particularly to the stationary magazine for weft replenishing looms, shown and described in my pending applicatiom No. 581,387, in which two or more guide-ways for superposed bobbins or filling carriers are used, and in which each set of bobbins is supported in its compartment, and at the desired time, the lowest bobbinofl one set is automatically released and drops down by gravity to the lower discharging end of the magazine, which end is common to all ofthe compartments. The selected bobbin is -yieldingly supported at said discharging end by retainlng means, comprising a spring actuated lever or supportat the head of the bobbin, on one side of the hea-d,v and a second spring actuated lever or support at the tip end of the bobbin, on the, opposite side of the bobbin; said levers are supported at the lower end of the magazine, in the usual and well known way.

The object'of my invention is to provide a second or supplemental yielding support for the tip end of the bobbin which comprises a plvota'lly mounted swinging lever, which yieldingly holds the tip of the bobbin, in addition to the ordinary yielding support. My supplemental support is intended to normally act as a stationary support, but incase of an improper transference of a bobbin, if the shuttle is not in hea of the bobbin is pushed too far through the shuttle; the tip end may project above the topof the shuttle, and catch in the magazine. In such case or cases, as the lay moves` back the bobbin or magazine may be broken; but by means of my supplemental yielding support in such case or cases,'said' Yfeatures of construction of `ments as will be hereinafter fully described. I have only shown in the l tached portion of a magazine for weft re! proper position, or for any otl1er cause,.the

prevent any injury- My nvention.consists in certain novel my 'improvedrawing a deplenfishinglooms, of the type above referred to, with my lmprovements combined therewith, suiic'ient to enable those skilled in the art to understand the construction and operation thereof.

AReferring to the drawingz-Figure 1 is an end View of a stationary magazinewith my improvements combined therewith. Fig'. l

2 is asection, on line 2, 2, Fig. 1, looking in the dlrectlon of arrow'a, same figure, and, Fig. 3 1s a detached View of a part of the frame, and the supplementallever or supv port, shown at the ferent position.

In the accompanying drawing, 1 is the inner end of a stationary magazine, which right in Fig. l, in a difsupports, by means of transverse rods 2, the

outer end- 3. The magazine is provided inV this instance with four guide-ways or verti- `cally extending compartments for the heads and tips of the bobbins 4,`which drop down by gravity to the lower discharging end 5 of the magazine. Each compartment or guideway is provided at its lower end with mechanism for sup orting a set of bobbins, and also for releaslng the lowest bobbinin each set. The hol 'ing and releasing mechanism consists of i. rocking support or cradle 6, pivotally Vmounted at the lower part of each compartment, and operated by upright bars 7, all as shown and described 1n pending application, Serial No.V

581,387, above referred to.

At the lower inner part of the magazine is a yielding lever or support 8 on one 'side of the head, for the head of a-bobbin 4, see Fig. 2; said lever-8 has its hub 8 loose on a rod 2. A helically coiled torsion spring 9 encircles the rod 2, and is secured at one end to a collar 1'0, fast on said rod 2, and is connected at its other'end with the hub 8 of the lever 8,

and acts to yieldingly hold the( lever 8 in its' raised position, with its free end in the path of the head of the bobbin, as shown in Fig. 2. At thc front end f the magazine is a corresponding yielding lever or support 11, for the tip end of the bobbins 4, see Fig. 1

but on the opposite sideof the bobbin 4 fromA the support 8.

All of the above mentioned partsimay be of the usual and well known construction in w -that is the central portion intermediate the upper end and the lower end, has pivotally mounted thereon the hub 13 of a downwardly extending arm` or leverv 13; the lower portion of the lever 13 is formed into a plate 13, which has an offset at 13', and is adapted to extend inwardly of the magazine, and into the athof and engage the tip end .of the bobblns 4. A lug 3 on the outer end of the magazine, limits the inward movement of said lever, 13, see Fig. '1.

An arm 13 on the lever 13, has pivotally connected thereto, the lower` end of a rod 14, which extends' upwardly and through a lug 3 on the magazine. A helically coiled expansion spring 15` encircles the rod 14, and bears at one end against the lug 3,'and

at its other end against the head of the rod` 14, and acts to yieldingly hold the lever 13 in its inward position, as shown. The plate 13 has in this-instance pivotally mounted. thereon, at its forward end 13 the front end 16', see Fig. 2, of a wire 16, which extends rearwardly under the plate 13", and then upwardly, with its other l end 16" preferably bent inwardly, and extending over the upper' edge of the extension 13" on the lever 13, but not attached thereto, so as toallow the wire 16 to move upwardly, and form a yielding surface for .the filling thread leading from thel shuttle.

The operation of my improved supplemental supporting lever will be readily understood by those skilled in the art from the above description in connection with the drawing, and briefly is as ollows:-In the normal operation of the loom, the bobbins are released, and dropped by gravity to the discharging end of the magazine, as shown in Fi s. 1 and 2, preparatory to being transferred into the active shuttle. The transferrer engages the bobbin at the proper time and pushes it downward, the yielding support 8 for the head of the bobbin, and thev support 11 for the tip of the bobbin, at the discharging end of the magazine, moving outwardly to allow the release of the bobbin in the usual Vway, and by supplemental support, through theA action of the spring 15 remainingFin its normal inward position, as shown in transference of the bobbin for any reason as the lay moves back, the supplemental support at the lower end of the lever 13 will move outwardly, against the action of ig. 1.. `In case of an improper` the spring 15. to the position shoiwn in Fig. 3, 'or to any intermediate position, and in. t-h1s vway prevent any injury to the bobbin,

or to the ma azine, as will be readily understood by t ose skilled in the art.

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

yI preferably have the pivot point for the downwardly extending lever 13 near the central portion of the magazine, that is the central portion between the up er end and the llower end, but if preferre the pivot point may be above said central portion, in which case a'longer lever 13 Awould be employed. By using a longer lever there 'would `be less movement at the lower-end of said lever.

Having thus described my invention, what I claim as new and desire' to secure by Letters Patent is i 1. The combination with a stationary magazine fora weft re lenishing loom having a plurality of guide-ways or' compartments for bobbins, of a yielding su port for the head of the bobbin, and a yiel ing sup. port for the tip of the bobbin, comprising a pivoted arm having its ulcrum adjacent the central part ofthe magazine, and hav- .ing an extension on its. lowerend adapted to extend under the' tip of the bobbin, 'and a spring for actuating said arm, to yieldingly hold it in normalposition.

2. The combination with a stationary magazine for a weft replenishing loom, having a plurality of .guide-.ways or compartments for bobbins, of a yielding support for the head of the bobbin, and a yielding support for the tip of the bobbin, said last mentioned support, comprising 'a pivoted arm having its ulcrum adjacent to or above the central part of the magazine,v

and normally held stationary by -a spring on the normal transfer of a bobbin. Y

3. The combination with a -stationary magazine for a weft replenishing loom, having a plurality of guide-ways or compartments for bobbins, of .a yielding support for the head of the bobbin, and ayield-v ing support for the tip of the bobbin, and a second yielding support for the tip of the bobbin, saidl last mentioned support2 comprlsing a pivotally mounted arm having its l fulcrum adjacent to or above the central part of the magazine, and normally held stationary by a spring on the normal transfer of a bobbin, and a guide-wire for -the filling thread,- .pivotally mounted on the lower end of said last .mentioned support,

and adapted to move back with said supi port, against the action of said spring.
