BOBBIN-STRIPPER.

Specification of Letters Patent.

Application filed April 5, 1912. Serial No. 688,667.

Patented Dee. 31,1 91".

To all whom it may concern:

Be it known that I, JOHN T. BnAznLL, a citizen of the United States, anda resident of Lanett, county of Chambers, State of Alabama, have invented certain new and useful Improvements in Bobbin-Strippers, of which the following is a full and clear specification reference being had to the accompanying drawings, in whieh- Figure l is a plan view of an apparatus embodying one form of my invention; Fig. 2 a side elevation thereof; Fig. 3 a vertical sectional view taken on the line 3% of Fig. 2; and Fig. 4 a vertical sectional view taken on a plane at right angles to the plane on which Fig. 3 is taken.

In the operation of the well known auto matic Draper loom when the filling-carrying bobbins or quills are ejected they have still remaining upon them a number of windings of yarn.

It is the purpose of the present invention to provide a simple apparatus for unwinding this yarn from the quills and winding it up on reels, from whence it may be removed, thereby cnabling this yarn to be recovered and utilized and the quills to be used again Without furthcreleaning, as more fully hereinafter set forth.

Journaled in a suitable frame is a pair o't parallel shafts a, each carrying a reel formed of side disks 7) and horizontal connecting bars 0, these two reels being arranged in the same horizontal plane and at a suitable distance from each other. .l igidly 'attached to each of the bars and pro jecting radially therefrom is a series ol? plates d which are arranged vertically edgewise and are provided along their outer edges each with a series of saw-tooth-shaped teeth facing in the direction oi rotation of the reel, this direction of rotation being indicated by the arrows, which arrows show that the zuljacent faces or sides of the reels are adapted to revolve upwardly, suitable gearing or belting being provided for this purpose.

A grating is hung on a pivot 0 above each of the reels these gratings hanging loosely so as to be capable of freely swinging toward and from each other. llach grating consists of horizontal cross bars f at the respective upper and lower ends of the grating and a series of separated guard bars The axis of the pivots e are parallel with the axes of the reels, and the guard bars 9' are curved in order to pass half around the reels, so that normally the lower cross bars f will lie approximately under-the centers of the respective reels. In operation the toothed plates or arms (Z work through the spaces between the bars g and project beyond the outer faces of the bars, as shown.

The reels and guard bars form the opposite sides of a hopper, the two other opposite sides of the hopper being formed by the two vertical boards hsupported in the frame of the machine. The quills containing the yarn are dumped into this hopper While the reels are rapidly rotated in the direction of the arrows, whereby the loose ends of the yarn are snagged by the picker teeth of the arms (I and are thereby carried around the reel. The bobbins or quills fall through the hopper into a suitable receptacle below and while in the act of falling and also after they have reached the receptacle the rotation ol the reels unwinds the yarn from the quills and winds it up upon the respective reels. As the reels fill with yarn, the guard bars will be pressed toward each other, thus narrowing the exit opening at the bottom of the hopper, and when the guard bars have been pressed toward each other sullicicntly to prevent the quillsdroppiug through, theapparatus must. be stopped and the yarn removed from the reels by cutting the yarn at a suitable point across the reel. 'lo guard the reels during the windingoperation 1 provide guanlboards [and in order that.thoseboardsmayheliltcd to expose the reels lor cutting oil 'the yarn, l hinge these boards at their upper edges. The quills are dropped into the hopper in masses.

.ll will be observed that the pickc' arms of each rocl pass up into the hopper or throat successively with respect to the pickers on the olhcr reel and that the result oi this is that the mass oi quills in the hopper is repeatedly shoved 'l'rom side to side, whereby the quills are shifted about snllicienlly to bring the loose, tree ends oi the yarn into the path ol one or the other set of picker teeth. In practice I have found that ii the reels are rotated. rapidly but a tow ol the quills get. down through the throat without having the loose ends of their yarn windings entangled in the teeth of the pickers. The low that get through the throat without being caught are separated from the stri 'iped quills and put through the machine again.

I have found in practice that the Width of the throat or passage between the outermost teeth on the respective arms of the reels may be four t) times the diameter of the quills the'machine is adapted to clean.

It Will be observed from Fig. 5 that the roW of teeth formed inthe outer edge of the picker arms or plates 62 is not on a line concentric with respect to the axis of the reel but on the contrary is arranged on a curve vthich is described from a oint eccentric-to the axis, whereby the stirrlng action of the picker arms as the arms pass up into the throat of the hopper is greatlyincreased and whereby also the possibility of the quills falling through Without having their yarnendssnagged by the teeth is reduced to a minimum.

Having thus described my invention, What I claim as new and desire to secure by Letters Patent, is

1. In a machine of the class set forth, a pair of oppositely disposed reels carrying picker teeth and means forming a hopper, means being provided for rotating the reels so that their adjacent sides shall. rotate upwardly and said reels being separated far enough to form a throat or passage-Way for the quills.

2. In a machine, of the class set forth, the combination of a pair of "reels carrying picker teeth, and means forming a hopper, said means consisting of side plates and guard bars curving around the ad acent sides of the reel.

3. In a machine of the class set forth, the combination of a pair of reels carrying picker teeth, and means forming a hopper,

roeaeoe said means consisting of side plates and guard bars curving around the adjacent sides of the reel, said guard bars being pivotally hung at their upper ends so as to be capable of swinging toward. each other.

4. In a machine of the class set fprth, the combination of a pair of reels each carrying radially projecting plates provided'yvith combination of a hopper embodying side boards and s aced uard bars a air of reels mounted behind the guard bars and having projecting arms which extend therebetween and Work in the hopper, said a ns provided With saw shaped teeth arrangedon a curve described from a point eccentric to the axis of the reel, and means for rapidly rotating thereels so that the arms shall Work up- Wardly through the hopper.

6. In a machine of the class set forth, the combination of a pair of reels carrying picker teeth, and means forming a hopper, said means consisting of side plates and guard bars curvin around the ad acent sides of the reel, the pic er teeth on one reel being arranged out of horizontal alinement With the picker teeth on the other reel so that they shall enter the hopper successively.

In testimony whereof I hereunto afiix my signature in the presence of two Witnesses.
