This invention relatesto devices that apply a coloring agent to alength of thread,`and has for itsmain feature-and object means whereby the device will cease to lbe operative l a predetermined time after it hasbeen set in operation. y i f ,n n

In the accompanying drawings the invention is disclosed in a concrete and preferred form in which: A y

Fig. 3 is a top plan view of the coloring device shown in Fig. 1, but shownmore in d etail and with kparts broken away and omit- Fig. 4 is a view in front elevation, with parts omitted and in section, looking substantially in the direction of arrow 4 of Fig. 3;

Fig. 7 is a more or less diagrammatic view i of the circuit arrangements employed to control the device; an l Fig. 8 is a diagrammatic View showing a wound thread having its inner convolutions impermanently colored or bleached. v 1

l indicates a support for a sourceof supply of thread, here shown as spools 2, from which spools the thread is drawn and wound on bobbins 3. .When bobbins 3 have been supplied with sufficient thread from the spools, said bobbins become in turn a source of supply for a lace-making or other machine. To notify the operator of the lace-making machine when the supply of thread on bob'- bins 3 is about to become exhausted it is kdesired to impermanently color the innermost convolutions of the thread wound on the bobbins, and such impermanent coloring may of course be produced by means of a wash able dye or by bleaching. In order to color the innermost convolutions of the thread of Fig-2 is a vertical sectional view substan- 1931'. serial No. 527,432.

bobbins 3 (see Fig. 8), a device is interposed between the spools and the bobbins located out of the path (indicated in full lines in Fig. 2) whichthe thread normally takesin passing from one to the other, and means'are provided to deflect the thread (indicated in dotted lines in Fig. 2) into engagement with the device. Y

l Inr the form of the invention here disclosed, 4f indicates a fountain and 5 is a fountain roll rotatably'mount'ed in the fountain and actuated by any suitable means such as pulley 6;, 7 is a drying roll mountedoutside of the fountain and in such position that the thread after engaging the fountain roll will engage thedrying'roll before it passes tothe bobbin'. The dryingroll may have a surface of absorbent material such as blotting paper, if desired.v 8 is a guide in the' form of a rod carried by arms 9 pivoted at 10. A spring 11 anchored on the frame at 12 normally urges the guideinto its upper or inactive position. 1,3 indicates a latch taking the form of a bar slidably mounted in brackets 14 and normally moved into latching position (to the right in Fig. 4) by means of a spring 15. Said latch carries two upright latching members 16 to engage arms 9, and it will be understood that when the operator desires to render the device operative to color the thread, he simply depresses guide 8, thereby bringing thethread into engagement with the rolls, and as said guide descends, the arms thereof engage the upright latching members and force'the latching bar to the left in Fig. Ll against the tension of spring 15, after which said latching bar clicks back and retains guide 8 in its operative position against the tension of spring 11. When it is desired to release the guide, the operator will press button 17 onthe end of the latching bar, there` by moving the latter to the left in Fig. 4 thus permittingspring y11 to move the guide into its upper or inactive position. f

The foregoing constitutes a complete, operative device, but if desired this device may be rendered semi-autoinatic in action, -for eX- ample by the following means. 18 indicates an electro-magneticdevice, here a solenoid, mounted on the framework, the core 19 lof which solenoid is connected by means of arm to latching bar 13, the parts being so arranged that, when the solenoid is energized, the latching bar will be moved to the left in Figs. 3 and 4 against the tension of spring 15. 21 indicates an auxiliary solenoid also mounted on the framework, the core 22 of which auxiliary solenoid is connected to switch arm 23 pivoted at 241 and adapted, when 21 is energized, to move contact spring 25 against contact spring 2G. Arm 23 also carries a projection 27 to be engaged by member 28 of arm 2() to separate springs 25 and 26 by turning 23 on its pivot when solenoid 18 is energized and latch bar 13 is moved to the left (Fig. 7). 29 and 30 indicate two contact springs laced in the path of revoluble contact mem er 31, here shown as bein operated by a timing device or stop cloci 32. This stop clock is so mounted on the framework (in brac Yet 33) that its stem 34 is beneath a projection 35 ot guide 8. It will now be understood that when the operator depresses guide 8 to bring the thread against the rolls, he likewise depresses stem 34 and starts the timing element. lf springs 25 and 26 are in contact, the movement of the latching bar (13) to the left (caused by the downward movement of guide 8) will separate the Springs. Contact member 31 now starts rotation and eventually encounters contact 29, thereby closing a circuit through solenoid 21 over wires 3G, 37 and battery 38 to member 31. This energizes 2l and closes contacts 25-26- Member 31 continues its rotation and eventually reaches contact 30, thereby closing a circuit through solenoid 18 over wire 30, contacts 25 and 26, wire 40, solenoid 18, wire 41, battery 38 to member 31. This energizes solenoid 18 and moves latching bar 13 to the left (Fig. 7) thereby releasing guide 8 (the latter moving upward under the compulsion of spring 11). The effect of this is to stop timing element 3l (stem 34 being permitted to rise), to break the circuit at 25-26 by the left-hand releasing movement of latching bar 13, and to permit the thread to resume its normal path out of contact with the rolls. It. will be evident therefore that, after a predetermined period or after a given length of thread has been colored, the device is automatically released.
