Claims.

The present invention relates-to new and useful improvementsfin adjustable bobbin'and battery holders forlooms ofa type di'slosed'in my oo-pending application-Serial No. "'744 ,362,- filed 1 April28, 1947 land more .paraticularly' to means for effectively holding bobbins in different types of batteries whereinthe height of the bobbin with respect to theholder. is not always uniform.

In some types-of batteries the-bobbins are'positioned higher than in others and accordingly it is an object of the present invention to provide a-bobbin-holding.-vplunger attached in positionto a battery and constructedto effectively hold-bobbins therein where a SllbSllnl'itiillY wide variation occurs in the height at which the bobbin is supported.

A further object is to provide an adjustable bobbin and battery holder adaptedfo'r att'achment to the usualbobbi'n battery orx'a loom for preventing movement ofthe" bobbin and battery and particularly to prevent "thelbobb'in' from turning in 'the battery, thereby reducing filling breakage on the change and which necessitates stoppage of the loom as well as're'sulting ina'n imperfect weave and loss in-production.

Another object is toprovidemeans for holding the loom battery against reverse or backward movement during operation 'of the loom and also to holdthe disk and "other parts of the battery against vibration 'tothus'reduce' wear of the moving parts.

A further object is to provide a device" of this character of simple an'dfipractical construction, which may be mounted in positionon the loom without necessitating any material 'change'sior alterations in the construction thereof, and which, at the same time, is'efficientand reliable in operation, relatively v inexpensive to' manufacture and otherwise 'well adapted for the purposes for which the sameis-intended,

Other objects and advantages reside in "the details of construction and operation as-mo're fully hereinafter described and claimed; reference being had to 'th'eaccoinpanyingdrawings forming parthereof, wherein like numerals refer to like parts throughout, and inwhioh:

Figure 1 is a transverse sectional view'df a loom battery showing the 3 bobbin holding attachment in position thereon; 1

Figure 2 is aperspective view of the detent pawl for the battery;

Figure 3 is a grouppers'pective View of the w Referring nowto thedr'awin'gs in detail-wherein for the purpose of illustration I have-disclosed a preferredembodiment of theinvention,

the numeral 5 designates .a loom battery disk 'ofconventionalconstruction and on whichflthe bobbins 6 are supported. The usual transfer hammer is-shown at 1 which is pivoted, as at 8,

ancl includes a-downwardly extending arm 9 op- -eratively conneoted to the dog 9a.

The loom also includes the battery stand I, lay

2, and a shuttle box 3 for receiving a shuttle 4 "from; the running shuttle'of'the 10o-m,-and to the stand is secured anlangle bracket H including an upwardly projecting forwardly curved fixed guide or abutment [2 for the bobbins 6, the guide (Jr-abutment [2 having a square shaped opening I3 therein formed with a'beveledcountersunk lower edge '14.

A sectional plunger composed of rear and front longitudinally aligned sections I5 andtfi is 'slidably mounted on the bracket II, the rear section iiibeing square shaped in cross section at itsrear end, and curved downwardly as shown at l 5a'and slidable in the opening l3. Thecurved .rear-end-of plunger section I5 is formed with a v-erticallgroove l-i aligning with the similar groove l8f-formed-in the-outer surface -of-the --up's'tanding abutment lZ-of the bracket H. The 'front end of the rear sectionrlfi of therplunger is threaded asat l5b. l

The front plunger section 16 is jslidably mounted in a guide 20 secured to-the other end ofthebracket I I, the frontsection 16 having a coma "2| secured in longitudinallyadjusted position thereon by a set screw.22.

abutmentWZ of'the bracket H is a relatively light coil'spring'25, A reari'relatively heavy coil spring '25 surrounds ithe'adj'acerit ends of the plunger -section's'l 5 andlfiwith one-end of the spring 28 bearingagainstthe'collar 21 and the other end of the spring 'bea'ringa'gainst the nut '24, the spring 26 holding the adjacent ends of the plungersections in'lo'ngitudinal alignment and in spaced apart relation withrespectto each other.

The front plunger-f5 isipositio'ned for engaging the'arrn 9 of'the transfer hammer"? 'andwith the *curvedreairerid "I5a of the rear plunger [5 in 'position'for engaging the'bobbins '5. The inner ends of the bobbins are usually provided with a'nnularribs '(notshown) adapted to seat'in the "grooves ll'an'd It, ahdth'e coil spring 2 exer'ts its influence on the plung'er It "to project the same rearwaral ortnenpturnee abutment [2 of "the -bracket tofirmlyholdthe bobbin, asshown in Fig-ure '1" of the drawings;

I Retrograde frm'we'm'ent of j'the' hopper is prevented by the" usual deteiit pawl "2 T 'pro'videdwith a lateral lug-29" carried "by "extension '32 *for engaging the inner iperiphery 'of thehang'e 31 of the ratchet wheel 3 l. The usual dog 33is pivoted to ha'mfnr *1 i and is provided with at lu'g #35 Efor enga'ging the teeth of ratchet 3! and coac'ts'with 1 this art.

detent pawl 2'! during the operation of the transfer mechanism.

In the operation of the device, when hammer I starts its downward motion, its downwardly extending arm 9 releases pressure against plunger section I6, allowing spring 25 to withdraw curved lower side of the bobbin in a position to exert end I50, from bobbin 6 and to position end l5a abutment l2 and with the grooves l'l a nd l8 aligned to receive the usual ring on the bobbin in opening l3 substantially flush with guide or H but (not shown) to guide the bobbin during its into position for engagement by the plunger.

hammer comes into contact with plunger I6 simultaneously compresses spring 26 allowing latch 2'! to drop in place to engage gear 3|, and the recoil of spring 26 moves plunger l5 forwardly against the bobbin to prevent the bobbin from turning. Also the pressure of plunger it:

against the bobbin in turn causes gear 3| to press tightly against detent pawl 21. This steadies and braces the disk 5 and prevents excessive wear of the moving parts due to loom vibration.

The detent pawl 21 also prevents reverse or backward rotation of the gear 3| and disk 5 when plunger l 5 moves rearwardly and thus holds the bobbin in proper position in line with the hammer for inserting the bobbin into the shuttle. The downwardly curved rear end [So of rear plunger l5, in its rearwardly projected position i will ride under the bobbin below its center to force the bobbin upwardly to more effectively hold the bobbin in the battery.

The curvature of the plunger also enables the same to effectively hold the bobbins which may not be carried at uniform height in batteries of diiferent types and without necessitating a change in the holder.

.To further compensate for variations in the height of the bobbins the head 15a of the rear plunger I5 is especially designed and formed with a downward extension l 50, as shown in Figure 5,

for use with low bobbins or with an upward extension I5d, as shown in Figure 6, for use with higher bobbins.

The face of each head is also formed. with a horizontal groove Ha intersecting vertical groove "end engageable with a bobbin carried by a battery at a point below the center of the bobbin to partially extend under the rounded lower side of the bobbin in a position to exert an upward pressure on thebobbin and a rearward pressure on the battery, means projecting the plunger into bobbin engaging position, and spring means retracting the plunger, said curved end of the plunger seating in the countersink of the opening when retracted.

3. A bobbin holding device for loom batteries comprising a bracket carried by a battery stand and having an upwardly projecting forwardly curved rear end provided with a non-circular opening, and a spring projected plunger conformably received in the opening, the rear end of the plunger engaging a bobbin as it approaches its position for delivery from the battery to the shuttle, said bobbin engaging end of the plunger having a vertical bobbin ring engaging groove and a l horizontal groove intersecting the vertical groove, said horizontal groove forming an antislipping serrated face on the plunger for gripping the bobbin.

4. A bobbin holding device for loom batteries comprising a bracket carried by a battery stand and having an upwardly projecting forwardly curved rear end provided with a non-circular opening, a spring projected plunger conformably received in the opening for sliding movement into and out of engagement with a bobbin as it approaches its position for delivery from the battery to the shuttle, and a downwardly projecting extension on the rear end of the plunger engag- 1 ing a bobbin below its center.

I! to afford greater traction against the bobbin between the usual bobbin rings.

In view of the foregoing description taken in conjunction with the accompanying drawings it is believed that a clear understanding of the construction, operation and advantages of the device will be quite apparent to those skilled in A more detailed description is accordingly deemed unnecessary.

It is to be understood, however, that even though there is herein shown and described a preferred embodiment of the invention the same is susceptible to certain changes fully compreas new is:

1. A bobbin holding device for loom batteries comprising a bracket mounted on a loom and 5. A bobbin holding device for loom batteries comprising a bracket carried by a battery stand and having an upwardly projecting forwardly curved rear end provided with a non-circular opening, a spring projected plunger conformably received in the opening for sliding movement into and out of engagement with a bobbin as it approaches its position for delivery from the battery to the shuttle, and an upwardly projecting extension on the rear end of the plunger engaging a 'bobbinbelow its center front, said plunger exerting an upward pressure on the bobbin at one side thereof. 1 I
