6 Claims. 1

In the manufacture of yarn from cotton or other textile fabrics it is customary with each process to mark the bobbins produced in order to indicate the nature of the yarn wound on'them for easy future identification. Bobbins from a spinning frame, for instance, are marked usually by colored chalk and directly on the yarn mass itself so that the operatives in a subsequent process will know at once that the bobbin carriesa certain size of yarn, length of staple, etc. The chalking is done by the operative after the bobbins are full and the machine stopped. In a frame where all the bobbins are dofied at the ,same time, the operative just prior to dofling walks along the side of the frame and marks each bobbin with the chalk; Some mills use bobbins with tips of definite color, one color being assigned to one kind or size of yarn, thus providing foridentification, but both systems have obvious inconveniences. bobbins takes considerable time, as does also the hand chalking, especially'in machines in which the bobbins become filled and are doflfed nonconcurrently, as the case with some automatic re-winding machines, where,it is necessary to 25 transfer the bobbins from one box to another marking each of them during the transfer. This invention has special advantage in the class of machines just mentioned and maybe made in the j form of an attachment easily applied to such machines. It functions by automatically marking each bobbin as it is delivered or ejected, thus saving labor and time.

The accompanying drawing shows the invention in attachment form applied to one of the winder heads of a winding machine in which each head delivers a wound bobbin as soon as it is filled, the bobbin in such machines being thus delivered at irregular intervals. The operative mechanism of such machines is well known and of no consequence to this invention. It is pointed out that these machines are adapted to wind bobbins of different styles and sizes, and the delivery chute is therefore of adequate dimension to take the largest.

Fig. 1 is a side elevation of a delivery chute, Fig. 2 a front elevation partly in section, both with the invention applied, and Fig. 3 is a side elevation schematically indicating the relation of the invention to a conventional winding head.

The term bobbin as used herein applie to any equivalent package sometimes called cop, pirn, etc. The chute is marked I and is shaped to turn, so far as may be necessary, each bobbin released by its winding head for, or to assure, end- The separation of colored Wise delivery of the bobbin from the outlet of the -chute, as will be seen in Figs. 1 and 3 and as wiilbe understood. The device of this invention is attached to it preferably by means of a bracket 2, or. is otherwise supported so as to hold a position close to the path of the bobbins as they leave the chute and preferably so that it maybegin its action on the bobbin while still partly within the chute, as indicated by the dotted lines. The device comprises a frame including or constituting a receptacle 3 containing a pigmentary substance, such as a fugitive dye or other pigment of selected color and a means, for example a wick 4, by which such pigment or dye is conveyed to the surface of a roller 5. The wick is a satisfactory conveyor for the pigment when liquid, which is preferred. The roller turns on a horizontal axis in a posl-' tion where the bobbin descending from the chute I will ride or slide over it as it leaves the chute in its passage to the receiving box or place of deposit below (not shown). The roller is substantially as long as the width of the chute orifice and its upper surface may be said to define a path for the bobbins that continues the bobbin path from the chute I and a path that the bobbins follow in the same endwise relation as that in which the'yleave the chute (Fig. 1).. In following such path the mass of yarn wound on the bobbin acquires a smear mark or stripe picked up from its contact with the roller surface which constitutes a conspicuous identification in any appropriate color. Since the pigment is nontenacious 'or fugitive, the coloration disappears under later treatment of the yarn. It becomes sufliciently transferred to the yarn by the mere gravity pressure of the bobbin upon the roller. Also any shape or size of bobbin thus receives the marking without requiring special adjustment for the wick. The roller surface is thus prepared for that purpose.

In the present case, the roller is driven intermittently, and in phase with the delivery of the bobbins from each individual chute, by means of a ratchet wheel 6 thereon, the driving pawl of which, 'I, is carried on a swinging arm 8 which arm i connected by a, bent wire link 9 with the actuating member ill of the escape door of the chute I. This escape arm is usually carried on the chute and is operated by the mechanism of the respective winding heads in phase with its dofling mechanism. As it rises to release the bobbin its connections Just referred to turn the roller forwardly a distance suificient to bring uppermost, and directly in the path of the bobbin, a portion of the roller surface freshly wetted by her or surface,

device the mark made is in the form of a stripe running lengthwise of the wound mass of yarn; such longitudinal marking can be readily seen and is preferred on that account. Its width depends on the shape of the pigment-carrying memand to some extent also on the character of the yarn, and such member can, of course, be modified as desired to give a different eifect. So long as the marking member carries pigment'ready to be picked up by the yarn contacting or rubbing upon it, it is not of consequence whether it is rotated or not, although it is preferred that the surface move somewhat and in the direction of the bobbin movement while the latter has contact with it, because this makes a mark of good definition.

Accordingly the driving pawl system is preferably'so related to the escape arm 10 that the roller is turning as the chute door opens and while the bobbin is sliding over it. The link 9 is connected to the arm l or'other escapement member, by simply hooking it in a drilled hole, thereafter bending the link to give it the proper effective length. Further adjustment or. the action is accomplished by shifting the position of the 'carrier ll of the ratchet retainer pawl II, as will be understood from the drawing, but no limitation is intended herein to themanner of presenting the pigment to the path of the bobbin except as specified in some of the claims- As shown in Fig. 3, the bobbin I3 is released from its winding position by the withdrawal of the winding chuck I4, which is accomplished by mechanism contained within the casing l5, and not necessary to be described because well known in the art. It will be observed that the bobbin falls butt first into chute I, where it is retained (for yarn cutting) until the escape door In is raised to release it and allow it to slide over the pigmented surface of the roller'5.

I claim:

1. In a textile machine delivering wound bobbins, the combination with a bobbin escape door, of a pigment-containing receptacle, a marking member having a surface associated with such receptacle, and defining a conducting path on which the bobbin has sliding contact and means operated by said door for supplying pigment from the receptacle to the surface on which the bobbin slides.

2. In a textile machine delivering bobbins wound with yarn, the combination with the delivery chuteand the escape means thereof, of a pigment-container having an arm extending upwardly therefrom and provided with means above. said container for attachment to said chute to hold said container adjacent the path followed by the bobbins leaving said escape means. a 1'0- tary marking member associated with said container for contact with such bobbins and operat- 4? ing means for said marking member connectable to said escape means for operation thereby.

3. In a. bobbin-winding machine, means for releasing bobbins when fully wound with yarn, a. receiving chute shaped to turn the released bobbin for endwise delivery from the outlet of the chute, in combination with means for providing a continuing path for the delivery of the bobbin in the'same endwise relation, said means including a relatively stationary pigment-carrying member on' which the bobbin slides during such continuing path, thereby making a smear stripe along substantially the full length of the wound yarn mass on the bobbin. I

4. In a bobbin-winding machine, means for releasing bobbins when fully wound with yarn, a receiving chute shaped to turn the released bobbin for endwise delivery from the outlet of the delivery chute for the bobbins, means including a bobbin-supporting roller mounted on each chute for marking the bobbins delivered thereby, and an actuating means for said roller operated by the winding head to which it is appurtenant.

6. A textile machine comprising a plurality of automatic bobbin-winding heads adapted for delivering wound bobbins, each of said heads comprising a receiving chute for the bobbin, shaped and adapted to turn the same into position for endwise delivery therefrom, means mounted on each chute, including a bobbin supporting roller for making a smear stripe on the bobbins delivered thereby, and an actuating means for said roller operated by the winding-head to which it is appurtenant.
