BoBBIN-soRTE a.

Application filed October 18,1915. Serial No. 56,542.

To all whom it may concern:

Be it known that I, HOWARD D. COLMAN, a citizen of the United States, residing at Rockford, in the county of Winnebago'and State of Illinois, have invented certain new and useful Improvements in Bobbin-Sorters, of which the following is a specification.

This invention relates to means for sorting bobbins with reference to the presence or absence of yarn upon the bobbins. While the invention is susceptible of various embodiments, and of being applied to various uses, it is herein disclosed as embodied in an apparatus for sorting the bobbins discharged from a spooler or winder.

In the accompanying drawings Figure l is a fragmental plan view of a conveyer for removing the spent bobbins from a winder or spooler, a conveyer for carrying the bobbins to the sorter, and a device for transferring the bobbins from the'first mentioned conveyer to the second mentioned conveyer. Fig. 2 is a perspective view of one of the elements ofvthe sorter. Fig. 3 is an elevation showing .the sorter-and a portion of the second mentioned conveyer. Fig. 4 is a fragmental sectional view taken in the plane of dotted line 4 of Fig. 3. Fig. 5 is a fragmental sectional view of the sorter. Fig. 6 is a fragmental, substantially top plan view of the sorter. Fig.7 is a fragmental detail view illustrating a means for supporting one of the shafts of the sorter. l

While the bobbins may be supplied to the sorter from any suitable source, and in any preferred manner, I have shown in Fig. 1

a portion of an endless bobbin conveyer 1 arranged to extend around a winder 'or spooler in position to receive the bobbinsa discharged from the bobbin-holders of the winder or spooler. The bobbins are transported by the conveyer 1 in single file with their butt ends a leading. 2 isfone of the wheels by means of which the conveyer 1 is driven and supported. 3, 4 and 5 are guards to prevent the escape of thebobbins from the conveyer. 6 is a wheel secured to a vertical shaft 7 and having a peripheral flange 8 which extends under the. conveyer 1. The wheel 6 has an annular vertically with the shaft 7.

extending flange-9 to guide the bobbins. 10 1s a stationary, curved guide'extendingconcentrically with the flange 9 to prevent the escape of the bobbins whilethe latter are passing from the conveyer 1 to the other conveyer hereinbefore referred to. A deflector 11 extends from one end of the guard 10' to a point close to the inner side of the conveyer 1 and serves to direct bobbins from the conveyer 1 to the wheel 6. One end of the guard 5 extends close to the flange 9, as shown.

The conveyervl and the transfer wheel 6 may be driven in any suitable manner. Herein is shown a drive-shaft 12 which is geared to a shaft 13, which in turn has a Patented May 22, 1917.

which the wheel 2 is connected. Shaft 13 also has a bevel-gear connection with a shaft 15, the latter having a bevel-gear connection The character and arrangement of the conveyer that receives bobbins from the transfer wheel depend upon the location of the sorter and other considerations. Herein is shown a conveyer 16 comprising an end less belt 17, said belt beingsupported upon two flanged pulleys '18 and 19v '(Figs. 1 and 3). The pulley -18'is mounted upon the shaft 15.- Pulley 19 is rotatably mounted upon a rod 20 which is supported in sockets 21 (Fig. 6) carried in the supporting frame.

The belt 17 is. provided with transverse cleats or flights 22 in order that the belt may be able to elevate. the bobbins. The upper run of the belt 17 is supported upon a'bar 23 (Figs. 1 and 3') fixed in the framework. At opposite sides of the upper run of the belt 17 are guide plates 24:, the lower ends, of which extend into operative relation to the flange 9 and the guide 10. The upper ends of the guard plates 24 extend within a curved casing 25 which incloses the upper portion of the pulley 19. The casing 25 is secured-to a frame '26,to be more fully described hereinafter.

To reduce the speed of the bobbins as they leave the casing '25, and to direct the bobbins downwardly, there is provided a gate 27 pivoted above the casing 25 at 28. A spring 29 tends to hold the gate 27 closed.

The sorter is arranged in position to receive bobbins discharged from the casing 25,

a side plate 30 (Fig. 4) and a top plate 31 tion, the sorter comprises a series of travel- I ing bobbin-receiving elements 32 arranged in an inclined position so that empty bobbins shall slide off the elements; said elements being provided with surfaces to which yarn will cling, in order that bobbins having yarn thereon shall not slide off said elements, but shall be carried by the elements to a point of discharge. Each of the elements 32 is in the form of a trough V-shaped in crosssection, and its inner surface is of such character as to prevent or retard the sliding of a bobbin having yarn thereon. Herein the troughs are shown as lined with a suitable material to which yarn will cling, as, for example, felt. To the lower end of each element 32 is secured a guide portion 33, also in trough form.

The elements 32 and guides 33 are secured to the lugs 34 of two endless chains 35, said chains runningover

sprocket wheels

36 and 37 The wheels 36 are fixed upon a shaft 38 which is mounted in bearings 39 on the frame 26. Said frame comprises the end 1nembers 40 and 41, which members are connected together by

channel bars

42 and 43.

The frame 26 is provided with alined bearings 44, 45 and 46 which are mounted upon the rod 20. The opposite side of the frame 26 is supported by a rod 47, which rod may be raised and lowered to change the angle of inclination of the frame 26' and consequently of the shorter elements 32. Herein is shown a screw-threaded rod 48 connected at its upper end to the rod 47 and having a nut 49; said nut has studs 50 that rest in sockets 51 carried by the supporting frame. By means of the screw 48 and nut 49, the angle of inclination of the sorter elements 32 may be changed as required by variations in the coefiicient of friction, due to changes in humidity and other causes.

The shaft 38 is driven from the pulley 19 through bevel gears 52 and 53, the pinion 52 being fixed to said pulley.

The sprocket wheels 37 are mounted upon a shaft 54 (Fig. 7), which shaft is supported in bearings which are adjustably mounted, as indicated in said figure, in order that slackness may be taken out of the chains 35. The upper runs of the chains 35 are supportedupon angle-iron rails 55.

The bobbin-receiving elements 32 extend in vertical planes parallel with the plane of l the conveyor 16, and travel at right angles to the plane of movement ofsaid conveyer. As hereinbefore stated, the series of elements 32 is arranged in position so that said tend beyondsaid element so that the entire I length of the body of the bobbin (or the yarn thereon) shall lie in contact withthe friction surface of the element 32. It will be seen that if the butt of the bobbin rested upon the friction surface of the element 32,

all of the body except the tip thereof would be spaced away from the friction surface, and unless the bobbin carried a considerable amount of yarn, the yarn would not be in contact with the friction surface. As, however, the body of the bobbin lies in contact with the friction surface, even a small amount of yarn is sufficient to prevent the bobbin from sliding. The guide 33 is sufficiently below the felt surface of the element 32 so that the butt of the bobbin shall i not space the body of the bobbin away from the felt. The plate 56 (Figs. 3 and 4) forms an end wall to limit any rebounding of the bobbin after the bobbin strikes the stop 57. The stop 57 is extended'in the direction of movement of the series of elements 32 and is beveled or inclined to permit bobbins carrying yarn to slide under restraint until the yarn has'effectively engaged the felt. Below the sorter is a hop per 58 located imposition to receive bobbins which slide off the elements 32 and guides 33. Beneath the discharge end of the sorter is a hopper 59 (Fig. 6) to receive bobbins discharged from the elements 32 as the latter pass around the sprocket wheels 37. lhe bobbins deposited in the hopper 58 may be sent directly to the spinning room; those that are received in the hopper 59 are subsequently freed from yarn, either by a stripping or clearing operation, or by unwinding the yarn in a special winder.

It will be seen that because of the troughlike form of theelements 32, and the position of the elements with reference to the line of discharge of the bobbins, said elements control the bobbins and prevent them from jumping and turning out of alinement with said elements.

at least two sorter elements shall pass the.

casing 25 for each flight 22 passing through said casing.

It'will be apparent that variouschanges may be made in the construction of the sorter without departing from the spirit and scope of the invention as set forth in the appended claims.

One embodiment of the invention herein claimed is shown in my copending application, Serial No. 450,523, filed October 31, 1908.
