BOBBIN Application filed January To all whom it may concern:
Be it known that I, Bonner SCHOFIELD, a
citizen of the United States, and a resident of South Dartmouth, in the county of Bristol and State of Massachusetts, have invented an Improvement in Bobbin Cleaners, of which the following description, in connection with the accompanying drawings, is
a specification, like characters on the drawings representing like parts.
This invention relates to bobbln cleaners or machines for removing bobbins. now the prior ejected usually to its complete or discarded filling carrier waste yarn from In filling replenishing looms it is common practice to replenish filling exhaustion and the or bobbin contains a small amount of yarn which must be stripped or cleaned from the bobbin yarn is by mechanical means,
practice prior to again placing upon the Where the stripped or cleaned from the bobbin as has been heretofore d, there is danger of injuring the bobbin itself during the stripping or cleaning operation, and
in order to overcome this objectionable action of the bobbin cleaners or strippers it has heretofore been proposed also to bobbins remove the waste yarn from the or yarn carriers by air currents which act upon the yarn on the bobbins or carriers and withdraw it therefrom.
The present invention relates to the last mention ed type of bobbin cleaners or strippers, and has for its object to provide a machine acting on the air cleaning principle which will more effectually remove the waste yarn from bobbins.
In accordance with the prevent invention, the bobbins containing waste yarn are placed upon presented to duit through which air duced by current inducing means. the air inducing means and present a holder and the yarn ends are the inlet opening of an air concurrents may be in- Between conduit, the invention provides means for sepafrom the air currents and gathering them into a receptacle from which they may be removed from time to time, while the air currents themselves may pass unimpeded under the current impulse of the inducing means.
The invention and new combination of p arts w lowi g ill best be made clear from the foldescription and the accompanying CLEANER.

drawings of one good form of a machine embodying the invention.
In the drawings:
Fig. 1 is a perspective view of a machine for cleaning waste yarn from bobbins embodying the present invention; and
Fig. 2 is an enlarged cross-sectionl view ot the yarn collecting tank and battle.
In accordance with the present invention, as shown, the air currents are induced by asuitable fan or air current inducing means, operated in the present instance bysuction, and the ends of the yarn from the bobbins to be cleaned are presented to the inlet'opening of an air conduit connected with the current inducing means, while between the air inducing means and conduit is interposed a yarn collecting and baflie tank.
In the drawings, Fig. 1, the air inducing means is shown as a pump or air suction means, indicated at 1, which may be actuated fromany suitable source of power, and as the details of such mechanism constitute no essential part of the present invention they are not herein shown and described except as to the relative position of such means and the other portions of the machine.
Mounted upon a suitable support or stand 2 is a projection or upright 3 on which is pivotally mounted at 4 a bobbin support I carrying arm 5 capable of swingi move-- ment about its pivotal mounting 1. lilach of the arms, one at each side of the pivotal support a, has mounted thereon a'bobbin holder which as shown comprises a disk 6 having a series of pins extending upwardly therefrom. Above the pins 7, which are utilized for holding individualbobbins, is another disk 8 provided with a series of yarn guides 9, and the two disks 6 and 8 are connected by a barrel 10 which may be appropriately supported for rotary movement upon its supporting arm 5, as indicated by dotted lines 11, Fig. 1. The guides 9 may be variously contrived and are herein shown as'of the pig-tail type, one of said pig-tail guides being carried by the disk 8 aboveeach of the pins 7 and preferably, though not necessarily, attached to the peripheral portion of the disk 8.
The bobbins having the waste yarn thereon may be supplied to the machine from a stand 12 which is herein shown as divided into two portions by the projection 13, onebobbins for the bobbins 14 having the waste yarn thereon, and the other for the bobbins when the Waste yarn has been removed therefrom.
Between the air current inducing means and the bobbin support or holder is a waste yarn collecting tank 15 having a door 16 at its lower portion from which the waste yarn may be removed from time to time.
The yarn collecting tank 15 is preferably formed cylindrical and has its top wall 17 formed with an opening 18 for the reception of the baiiie 19. The bafile 19 comprises a substantially cylindrical member having the top plate 20, the edgesof which at 21 rest upon the top wall 1.7, while the cylindrical portion of the balile extends through the opening 18 from which it may be removed from time to time when desired.
Between the baiiie 19 and the air inducing means 1 is the suction pipe 22, the end of said pipe extending through an opening 23 in the top wall 20 of the battle and forming therewith a substantially air-tight joint.
The baffle 19 has an o ien lower portion 2a which is covered by a screen which may be secured about the edges of the opening 24 at 26, as shown, the construction being such that upon operation of the air inducing means 1, air currents wil be created through the bafiie 19 and passed, as indicated by the arrows in Fig. 2, into the pipe 22 connected with the current creating means. Connected with the yarn collecting tank 15 is the air conduit 27 which communicates with the tank 15 at a point opposite the solid walls of the baffle which extend downwardly into the yarn collecting tank, as indicated in Fig. 2 the result being that as the air currents are induced through the conduit 27, in the directionl indicated by the arrows, Fig. 2, and carry with them the waste yarn ends a, such induced currents will strike the solid wall of the battle presented to the open ing 28 of the conduit 27 and will take a downward direction, as indicated by the arrows, thereby permitting the waste ends ato travel downwardly into the yarn collecting tank 15, while the air currents themselves will pass about the bottom of the baffle 19 through the screen 25 to the air inducing means. This method of separating the waste yarn ends from the air currents is found to be efiicient and practical, in that the traveling yarn ends a as they enter the yarn collecting tank will by their momentum pass downwardly in the tank, as indicated in Fig. 2, while the air currents themselves will pass about the solid portion of the baffle and enter through the screen 25 freed from waste yarn. This characteristic operation of the machine is also emphasized from the fact that during the cleaning of a series of bobbins, a plurality of the yarn ends are collected together and withdrawn from the as the ends are carried by the induced air currents through the conduit 27, such mass of yarn having s'ufiicient momentum to carry them as hereinbefore described, downwardly in the yarn collecting tank, thus freeing them from the air currents which pass through the bottom of the baflie.
The inlet opening 29 of the air conduit is preferably formed flaring or trumpet-like, as indicated in Fig. l, and is arranged adjacent to or above the bobbin holder. Between the inlet opening 29 of the air conduit and the bobbin. holder is a yarn end gathering guide for gathering the ends of the yarn leading from the bobbins and presenting them in bunched relation at the entrance of the air conduit. As shown, the yarn gathering guide 30 has a gathering portion 31 disposed opposite the flan ing opening 29 of the air conduit, and may be conveniently supported, as shown, by the collar 32 which may be clamped about the conduit 27 at the base of the flaring end portion 29 thereof.
When a series of bobbins containing waste yarn are to be cleaned or stripped of the yarn thereon, they are placed upon the supporting pins '3 when the bobbin holder itself is in its idle or non-stripping position, as indicated at the right of Fig. 1. The bobbin holder supporting arm 5 is then swung around its pivotal support l to place the bobbin holder adjacent the inlet opening of the conduit, as indicated at the left, Fig. 1, and thereupon the attendant pulls a small length of yarn from each bobbin, passes it through its appropriate guide above each bobbin, gathers the several ends of the yarn together and places them over the yarn gatherer at the mouth of the conduit, as indicated in Fig. l, whereupon the induced air currents passing into the conduit 27 withdraw the yarn endwise from the bobbins in gathered relation and carry them along with the induced air currents into the yarn gathering tank 15, and since the air conduit 27 has its delivery opening 28 opposite the solid walls of the baflie, the gathered ends of the yarn take a downward course in the yarn collect ing tank, while the induced air currents freed of their yarn load, pass about the baflle and upwardly through the screened lower end thereof.
Should it be desirable at any time 'to clean the baffle it is only necessary to lift the baffle bodily from the yarn collecting tank, remove the accumulation of lint, if there be any, and return the parts into their working relation, as indicated in Fig. 2.
From the construction described it will be apparent that during the stripping or clean ing of a series of bobbins from the bobbin holder opposite or adjacent the inlet of the conduit, the attendant may be placing another series of bobbins on the companion lit) bobbin holder, and when one series of bobbins has been cleaned the attendant may then turn the supporting arm to carry the cleaned bobbins into their removing position and the bobbins hav ng waste yarn into from bobbins, the combination of a holder,
for supporting a series of bobbins, an air conduit having an inlet opening adjacent the bobbin holder, a series of guides for directing the yarn from said bobbins towards the inlet opening of the air conduit and a gathering guide for gathering the series of yarns opposite the entrance to the air conduit.
