application filed liiCCillbGi o v2. ii iiifl (20 i m th t i, l ihuyrnn H. Viburni oi. the United Sta-es, residi the count of ll orc cit-ate oi ssachnsetts, have in- I a new and useful Bobbin Antirolling ishing liliechanisin, of which the fola specification. invention relates to nnilti-color well i anisn'i and more parti-cto to means Ior preventing the rolling of the llfiljblllfl due to the vibation of the looin as the latter 1 operation.
in the type of replenishing mechanism shown in Patent l lo. .l OStlJ lS, the bobbins are arranged in stac it one stack for each l'nliii', and lie in substantially vertical guidewavs at the lower end oi which are provided readies orother do ices for delivering one )bin at a time transfer position. The sis of the yarn on the spare bobbins enlend to the thread holder atone side ot the J ilenishing mechanism and when the yarn is line the bobl ins remain in the stacks tor a considerable length of time during; which the ends Q); ending to the thread holder become entann'h l. 'llhis condition is brought about largely o the rolling or rotation of the bobbins on their own axes due to the vibration of the eplenishing n'iechanisni as the loom operates.
in ollori to prevent this rolling was made in a reph-znishing mechanism inade accordan application liled May 2?, 1922, Serial No. 584 187, wherein the are composed of a series H disposed runs each run mronnnooat .15.: but one bobbin. lVith such an arrangement it has been found that as the bobbins niove downwardly they rotate in a manner similar to meshing gears, alternate lmbbins moving); in the same direction down their associated inclined runs while the intervening bobbins niove oppositely and are given an opposite rotation.
it is the object of my present invention to Iitilire the general principle dicslosed in said application but to arrange the bobbins and angular runs in such a way that all rolation oi": the bobbins will be prevented Accordingly l have constructed the short ann nlarly disposed runs of uiiicient length to t its at least two bobbins so that as a number of bobbins having frictional conea, Serial No. ceases.
tact with each other move down each run lie tendency to rotate in the same direction will be prevented by their frictional conract, the result of which is that the bobbins will more down the guideway without roost are; on their own axes.
ll ith this general object in view, my inv ntion resides in the combination and arclaimed.
in the drawings wherein two forms oil any invention are disclosed,
F l an end elevation of an inner portion of a weft replenishing mechanism with the bobbins shown in dotted lines,
Fig. 2 is a vertical section taken along the 2- 2 of Fig. 1, and 'g. 3 is a fragmentary view similar to l but showing the bobbins arranged in a d 1 .rent manner.
Referring to the drawin 's, it will be seen that the n'nigazine is provided with stand '10 formed as part of a foot 11 which may be attached in any way to the loom side. A 'lraine 12 is preferably formed as part of the stand and is provided with a plurality of substantially vertical guideways l3, 1%. l5 and 16, defined between ribs 1.7, 18, 19. and 21, formed as part of the frame 12 and projecting laterally therefrom. In the wer portion 01" each guideway provision is made for cradles or other bobbin controlling devices 22, indicated more particularly in Fig. having slots 23 and 24 which may l made as shown in Patent No. 1 005 321, sued October 10, 1911. While this pan ticnlar form of bobbin control is shown, yet it is to be understood that any form of control may be employed such, for instance, as that shown in the patent to Wynian No. 941,179.
My invention relates more particularly to the :torrnation of the gaideways and it will be seen from Fig. 1 that each gnideway is provided with a series of relatively short runs angrilarly disposed with respect to each other. The runs 24: and 25 are shown as extending downwardly to the left while the runs 26 and 27 connected therewith are shown as running downwardly to the right. These runs are made of sutlicient length to accommodate at least two bobbins.
in the operation of the replenishing niechanisni when a Weli't change is about to occur, the slots 23 and undergo a relative motion, the result of which is to open the cradle for the reception of the lowest bobbin in the associated stack. When this occurs, the bobbins will move down the guideway in which they are contained and because of the fact that each run a'ceon'nnodates a pair of bobbins which are held in contact with each other by the weight of the superimposed bobbins, it is apparent that any tendency to rotate because of movement down an inclined surface will be counteracted. When the bobbins are arranged as shown herein, it has been found that the uppermost bobbin will move to the bottom of the guideway without undergoing any appreciable rotation. In providing an even number of bobbins for each of the angular runs, the tendency of half the bobbins to rotate in a right hand direction under influence of the incline will be counteracted by the opposite tendency of the other bobbins to rotate in the same direction, the frictional contact of the bobbins preventing rotation.
In Fig. 1 I have shown the-bobbins so disposed that a bobbin is located in each angle of the guideway but it is possible to have the guideways so arranged with respect to the cradles that the bobbins will be arranged as shown in Fig. 3 wherein the bobbins are located in that portion of the run intermediate the angles of the guideways.
Having thus described my invention, it will be evident that changes and modifications may be made by those skilled in the art without departing from the spirit and scope of the invention as set forth in the appended claims, and I do not wish to be otherwise limited to the details herein disclosed.
lVhat I claim is:
1. In a weft replenishing mechanism, a guide-way adapted to receive a stack of bobbins therein,means to lower said stack of bobbins progressively in said guide-way, said guide-way being made of a plurality of alternately inclined connecting runs and each run being of suflicient length to accommodate a plurality out bobbins.
2. I11 a weft replenishing mechanism, a guide-Way adapted to receive a stack of bobbins therein, means to lower said stack 01": bobbins progressively in said guide-way, said guide-Way being made of a plurality of alternately inclined connected runs and each run being of sufficient length to acconn'nodate an even number of bobbins.
3. In a weft replenishing mechanism, a guide-way adapted to receive a stack of bobbins therein, means to lower said stack of bobbins progressively in said guide-way, said guide-way being made oi. a plurality of al ternately inclined connected runs and each run being of suiticient length to accommodate a pair of bobbins.
In testimony whereof I have hereunto atfixed my signature.
