MOUNTING FOR YARN-FRAME CLIPS.

Application filed June 23, 1924. Serial'No. 721,778.

fo all io/mm 'it may cti/noem:

Be it known that I, Vieron Giano, ya citizen of the United States, and a resident of Philadelphia, county of Philadelphia, State of Pennsylvania, have invented certain new and useful Improvements in Mountings for Yarnlrame Clips, of which the following is a specication.

The present invention relates to tuft-yarn frames and more particularly to the clip mechanism by which the respective frames are attached to and released from'the frame conveyor chains.

Some of the objects of the present invention arc to provideaii improved means for .mounting spring clips on, the ends ofi-a yarn frame; to provide a mounting for spring clips which eliminates screws. oi other fastening devices ofthe type which hold the clip by entering the end of the frame and are objectionable because they work loose Vand back out of the frame to a position where they throw the frame outro-f alinement and more frequently cause the frame to become disconnected from the conveyer chain; to providean improved retainer for spring clips which is rigidly held against movement lengthwise of the frame;

to provide ,a holder for spring clips which can be applied to existing clip frameconfstructions quickly. economically and without any change in the relation of the clip to its associated parts; and to provide other improvements as will hereinafter appear. i

In the accompanying drawings, Fig. 1

represents aside elevation of an end of a tutt yarn frame provided with a clip hold er embodying one form ofthe .present inl vention; Fig. 2 represents an end yelevation of the saine; Fig. 3 represents a section on line 3 of Fig. Q; and Fig. d represents a perspective of lone form of clip holder.

leferringto the drawings, an 'end of a tuft yarn frame lOis shown which is of the type formed of a wooden bar 1 1 encased in a vmetal tube 12 and of a lengt-li to operate with the particular loom for which it is intended. In so far as the present invention is concerned, it seems unnecessary to illustrate both ends of the frame as it will be understood the two constructions are the same.

rihe end of the frame 10 is provided with rigid uprights 13 and 14, the former serving as the support for the yarn spool and Athe. latter being offset therefrom to engage a link of the chain by which the frame is carried. Interposed between the uprights 1) and 14 is a spring clip 15 of the usual form which extends from the end of the frame 10 upwardly and outwardly to be held by-spring tension against the end of the chain engaging upright 14. A suitable slot 1G is formed in an offset portion 17 of the upright 1d in order to pass the clip` 15 to its operative position.

For the purpose of mounting the clip 15 on the end of the frame 10 it is provided with two openings 1S which are located to register with like openings 19 in the base portion of the'upright 14 and in alinement with the end of the frame 10.L These openvings 518 and 19 may be the customary Aholes Vto receive the screws by which the clips have heretofore been secured to theupright 1d or to the end of ,the frame 10. Ink accordance wit-h the present invention a holder `QOis provided having a flat base 21erranged to seat on the bottom of t-lievfraine 110, and an extension arm 22 arrai'iged at anV angle theretoA which is preferably slight-ly greater. than a right angle. This arm 22 vin operative position extends from the base Q1 upwardly over the end ofthe frame 1() and loverlapping thatv portion ofthe lspring clip 15 which seats on the upright,

14. Laterally extending from the arm 22 towards the end of the fra-ine are two lug prongs 23 which are spaced and located to pass respectively through the two sets of openings 18 and 19 zwhere, for purposes .of

more securely` linterlocking the parts, they may be embedded in the end of the bar 11.

In order to rigidly hold the arm E22 in its interlocked position clamping the clip to the end of the frame, it is fixed to the bottom of the frame 10.by screws 2411er other suitable fastening means enteringthe bottom ofithe frame 10, the holes for fsuch fastening' means ,being sov located in the frame 10 as to position the arm 22 inrabut- 'ting relation to the spring clip .15.f vIt should Vbe noted that the length of the arm is such as to extend beyond the flatseating part of the c lip so that its end rests against the angularly disposed part of vthe clip. This construct-ion provides a clearance space Q5 between the said arm 22 and the clip 15 whereby the clip is not exed along a sharp edge but has suificient play to distribute the bending stress` vAlso the clip l is 'backed or reinforced by aseparate spring strip '26 Whichsupplements the spring action of the clip l5 and prolongs the life of the clip. n

5 It will now be apparent that a complete unitary holdingmeanshas been provided for spring clips which is simple in construction, effec-tive inoperation and serves to maintain the clip properly supported nvhile providingz a smooth contactsface posi- "tioned towards'the conveyor chain.

In `clip constructions yas heretofore used vit has been customary toeinploy machine or Wood-screws forlfastening the clip to the end offtheyarn'i'rame and as a result, when :thesescreivsWork loose, astheyvare doing Vall the time, the added .length of theirame vdue to the projectinf screws not only7 throws the iframes out of position but more `often causes them to be forced out of the conveyor vchain. As these frames `Weigh many pounds apiece it is a serious thing,- when one is `forced out and dropsffromthe-conveyor, 1 the resulting' damage requiring ina-ny hours l-lost time in the `opera-tion of the loom. -Further, theworling out of the fastening screws is so common that expert loom repairers yare yrequiredito Ybe iniconstant atitendance.

3o By the .device 'of the presentinvention the foregoing; defects o-f'yprior; constructions are rentirely eliminated Yand afteraholder .of 'jthismew type '.isin place, there is nothing to ya ry `the length of the frame 4orto obstruct ',thegjpath `offthe conveyor chain` .or its as- ;socifated parts Furthermore, 'by the provision. `of a plurality of' interttittinglugs, the clip isffirm'ly held lagainstimovement:relaf tive to either l'the upright f or f the holder.

40 Attention is: also directed to thefact that the frames to which these` clips..are.applied yare Inine ffeet; or-:more long :and tivoimen are required tothandle each frame when it is Aplaced inrthe loom, solthat itrwillwreadily "beseen that ifoneof :thefframes is displaced :onaceount .of the usual screwiastening .means Working loose,y that.. Vresulting damage iis not only; aptftof-be:heavy,'butfvvhen one AIVframe ,drops vout ofv thef chain, litiv generally .carriesseveral others-With it and the entire :loom is putout ofr commission.`

Inl connection-With: the clip holding means :of :the :present invention, -it :Will be :noted fthatxtheiholders Which carry thevintertting `prongs are interchangeable,andrea-n beused at both ends of the frame instead of having` to provide one holder asa righthand holder andthe other as a left-handholdeiz 'Vhile only a single form is shown in `Which this invention-may: be embodied, it is to be understood that the invention is not @limited to :eanyvspeciic construction, but might be applied to various forms Without Ydepa'rtingffrom'the spirit of the invention or the scope of the appended claims.
