It is an object of this invention to provide a yarn carrier painting apparatus in which'an improved mechanism is employed for moving a marking brush into contact with a carrier, and also in which an improved means is provided for holding the brush in contact with the carrier for a predetermined length oftime.

Specifically, the improved structure, in part, comprises a rotating spindle for supporting a yarn holder, in combination with a'cam for positively moving a paint brush toward and away from the holder, and a clutch for connecting and disconnecting the cam with a suitable driving means,

The improved structure insures that each carrier will be engaged by the brushfor the same length of time and thereby will receive a I marked.

coat of marking material substantially the same as the coat applied to each of the preceding carriers.

It is another object of thisinvention to provide a marking apparatusof the class described in which manually operable means are provided for connecting the brush advancing cam with its driving means, and automatic means for disconnecting said cam from its driving means after a coating of marking material has been applied.

Some of the objects of the invention having been stated, other objects will appear as the description proceeds, when taken in connection with the accompanying drawings, in which Figure l is an elevation of my improved coating apparatus for yarn carriers and the like;

Figure 11 is an isometric view showingthe cam means for pumping predetermined quanti-' ties of markingmaterial upon the brush, and also showing means for turning the brusha' partial: revolution each time a yarn carrier is Brush support and advancing structure Referring more specifically to the drawings, the numeral lfldenotes' a suitable base member which has extending upwardly from the central portion thereof a suitable shaft ll. Thisshaft hasintegral with its upper portion a restricted shaft portion lla around which a sleeve or pipe I2 is rotatably mounted, said sleeve havingone end of :a lever l4 secured thereto. This lever ex tends downwardly and thenlaterally, and has a suitable slot iii in the outstanding leg thereof, which is penetrated by an upstanding arm IS. The arm I6 extends upwardly from a horizontally disposed shaft ll, said shaft ll being rotatably mounted in a suitable hearing such as counter casing I8. Shaft ll has another arm l9 extending laterally therefrom, and the free end of this arm l9 rests upon the upper end of a vertically disposed plunger 20, which plunger is mounted for vertical sliding movement in a suitablecollar 2| secured in base member l0, previously de-' scribed. A suitable cam.22 is provided in such a position that the lower end of the plunger will rest upon the periphery thereof. Therefore, as the cam 22 rotates the sleeve I2 will be oscillated back and forth around portion I la by means-of members [4 to 20. Thepurpose of providing the oscillating sleeve I2 is to have means whereby a suitable paintbrush or other marking means 28 can be-moved into and out of contact with This brush and associated mechanism is mounted upon a suitable bracket 25, said bracket being secured to sleeve 12 by any suitable means such as screws 26. Rotatably mounted in the bracket 25 is a brush shaft 21 (Figure 8) said brush shaft having secured on the projecting end thereof brush 28. As the brush 28 swings laterally through an arc whose center is shaft Ha (Figures 2 and 3) the end of the brush contacts the upper end of yarn carrier 30. The carrier 3B is removably mounted on a suitable spindle 3 I.

Yarn carrier support and rotating means The spindle 3| has a whorl 32 integral with the intermediate portion thereof, and the lower portion of spindle 3| is rotatably mounted in a bolster 33 which, in turn, is secured to supporting member l0. As a means for constantly driving the whorl 32, spindle 3| and the yarn carrier 30, a suitable belt 34 is provided which belt 34 is also mounted upon a pulley 35 secured on the end of a motor shaft 35. This motor shaft is driven by a conventional motor 31 mounted on the support I0.

Since the yarn carrier is constantly rotated by the motor 31, a supply of coating material which is on the brush will be applied to the yarn carrier each time the brush 28 is advanced to contacting position. The brush 28, however, is moved into engagement with the tip of the yarn carrier 30 by means of the cam 22 previously described. As a. means for normally rotating the brush 28 away from the yarn carrier 30 and for holding plunger 30 in engagement with cam 22 at all times, a suitable torsion spring ;49 is provided (Figure 2), one end of said torsion spring being secured to shaft l1 and the other end of the torsion spring being secured to counter housing 18.

. This torsion spring normally rotates the shaft I1 and its associated arms I6 and I9 in a counterclockwise manner in Figure 1 to thereby cause the brush 28 to be normally forced away from the observer. It is only when the positive force exerted by'the rotation of cam 22 is appliedthat the force of the spring 28 is overcome and the brush 28 is moved to dotted line contacting position as shown in Figure 2.

Brash rotating means It is preferable that the brush 28 be intermittently rotated about its axis so that all portions thereof will contact an object to be marked in a continuous operation. If only one side of the brush were to contact the yarn carriers, the bristles would become set in one position and would.

not apply a uniform coating of paint to the yarn carriers after a short period of use. By providing means for rotating the brush to different positions, all sides of the brush are permitted to contact carriers and therefore a much more satisfactory marking operation is effected. This rotation of the brush 23 is produced by a structure that will be presently described.

1 By referring to Figure .8. it will be seen that the shaft 21 has fixedly secured therearound, a pinion 48, said pinion meshing with a larger pinion 49, which, in turn, is rotatably mounted upon another shaft 50. This shaft 50 is secured in bracket 25. Integral with the pinion 49 is a ratchet wheel 5|, the teeth of which are engaged by a suitable pawl 52.

By referring to Figures 3, 4, 8 and 11 the details ofpawl 52and associated structure can be seen.- This pawl is L-shaped'and is pivoted intermediate its ends as at 53, to the lower end of a bracket 54, said bracket having a laterally disposed leg 55 in which a vertically disposed bore 56 is provided (Figure 11). This bore fits overthe upper end of shaft Ha and is rigidly secured thereto-by any suitable means such as a set screw 51. In order to normally urge the pawl 52in a counter-clockwise manner in Figures 3 and 11, at all times, a suitable compression spring EQ-is provided, one end of which is firmly pressed against the vertical leg of the pawl by any suitable means such as a headed screw 60. This screw penetrates a suitable slot 6| (Figure 9) in the vertical leg and-has the small and thereof threadably mounted in the lower end of bracket member 54.

Especial attention is calledto the fact that the parts 52 to 69 inclusive remain substantially in a stationary position except for the limitedarnount of rotation permitted pawl 52. On the other hand, the bracket 25-together with-its associated membersZG, 21,28, 48, 4Q, 50, and El are mounted for rotation as a unit around shaft Ha. In other words, the brush 28 moves laterally from the position shown in Figure 3 to the position shown in Figure 3A, during a marking operation. This lateral movement of the brush 28 along with the ratchet wheel 5| is sufficient to cause the free end of the dog 52 to engage an adjacent tooth in the-ratchet wheel 5 I, and therefore when the ratchet wheel returns to the normal position as shown in Figure 3, it will be rotated a distance of one tooth to thereby cause pinions48 and 49, shaft 2-?- and brush 28 to rotate a corresponding amount. The teeth of the ratchet wheel 5! are also engaged by a locking dog said dog having its upper and rotatably mounted in bracket 25 as at 65, and having its free end normally engaging one of the notches in the ratchet wheel. Member 65 prevents reverse rotation of the ratchet wheel 5| and its associated parts and thereby insures that the brush 28 will remain in the position to which it has been rotated while'thedog 52 is moving reversely over the ratchet teeth It will also be noted that by observing Figures 3 and 9 that the bristles of the brush 28- are flattened into a compact mass, the flattened side of which is disposed at anacute angle to a vertical position. By placing the flattened brush 28 at this angle, it is in a better position to receive the contents such as paint and the like from a dispensing pipe 10' thereabove.

' Dispensing mechanism for the marking material It is very desirable'that, a predetermined quantity of marking material may be applied to the brush 28- each time a ya fnholder is painted or .marked. Unless such a mechanism is provided,

viding this dispensing mechanism a suitable plate a ua e His secured tothe upper portion of bracket by any suitable means such as ascrew 12 This plate member H formsa baseupon which a container M is adaptedto'r emovably fit.. In order to hold the container l4 upon the platform ii a suitable spring lip 15is provided, which spring lip forms an integral portion of plate.

member 1 l. The lip 15 has a hole 76 in the ver; tical leg thereof which hole fits over a pin or'projection 71 extending from one side of container MI When the lip 75 is in the position shown in Figure 8, the oppositeside of the cam 74 pressed into hooked portions 19- to thereby hold the' container in clamped position. This con- Another bore 88 is provided in alinement with bores 83 and 87 This last-named bore 89, communicates with a vertically disposed cylinder 90 in which is slidably mounted a piston iii. Lead,-

ing from the upper side of piston 9i i is a rod 92 which slidably penetrates a cap member 94 which cap covers cylinder 90. On the'upperend of rod 92 an enlarged head 96 is providedfor confining a spring 98 around rodQZ.

It, willbenoted that the spring s3 normally tends to-iorcepiston 9i, shaft 92, and head 96 upwardly at all times. ;Of course, when.members ill, 92 and 96 move upwardly, a charge of painter marking fluid B0 is drawn. inwardly throughbores 83, 81 and 89 and into cylinder 99.

Leading from the lowerportion of the cylinder 90 is another bore 99 over which alballlfiil is adapted to fit, which ball is disposed inside of an e nlarged bore lfll. This enlarged bore IOI has accompression spring Hi2 therein fornormally pressing the ball lilii over the openingior bore As a means for confining spring 102 within the bore lill, one endof a, suitable L-shaped dispensing pipe 78, previously, described, is threadably secured in the end of bore Iiil. Ball serves as a check valve as piston 91 moves downwardlyv to discharge the contents from cylinder whereas ball Nil) serves as a check valve While piston 9|; moves upwardly to draw a supply of marking material into the cylinder Bil.

When the brush 28, together with container l4, fitting 82, and dispensing pipe 70, is moved 1 from the position shown in Figure'3 to the position shown in Figure 3A, the upper end of head portion is not depressed by any mechanism,

and therefore, is moved upwardly the maximum amount by spring 98, where a full charge of marking material will be drawn into cylinder 90.

When the parts justnamed return to normal position as shown in Figure 3, the head portion 96 is automatically depressed to lower the piston Si and to discharge a predetermined portion of marking material from the cylinder 99 through I boresiiii and iii! and 28;

Thi s'means for engaging and depressing the head portion 96 comprises a suitable T-shaped bariiiE, the upperportion of said bar being piv-r oted'as at W6 to the bracket member 54. One of the laterally disposed legs of this bar 95 has through pipe 18 onto brush a'cam-surface I01 formed on the lower side thereof which serves asa base against whichthe head portion '96 slidably contacts when it moves,

from the position shown in Figure 3A to the position shown in Figure 3.

In order to insure that the lower portion of the lower cam surface l 0 1 will properly engage'thej headv portion 96, a suitable spring I I0 is provided. This spring is disposed between the vertical legs of the T-shaped member 15 and the face of bracket 54. A pin or screw III has one one thereof-threadably secured in the vertical leg of T\-shaped bar 185, said pin penetrating a slot H2 inthe bracket 54, and supporting the compression spring lllltherearound, This compres sion normally tends; to rotatethe T-shaped bar; 35 in a clockwise manner to the position shown in Figure 3A, when the brush 28 is in contacting position iwith;holder 30. I As; thebrush returns to normalposition as shown in Figure 3, along with the containerlfl and fitting 82,-the, head portion 96 will move beneath thecamsurface, I 9'! and the farther it moves to the right in Figure 3, the more the head portion 36, together with cylinder 9! will be depressed. ,In other words, the piston 9| is depressedby cam surface It]? as a result of therotation of member I05- when itsv vertical leg is" engaged bythe moving bracket 25 durin the return of the parts to normal positionas shoWn-in Figure 3.

Clutch mechanism From the foregoing description, it is seen that as cam 22 (Figures 4, 5 and 6) rotates, the brush 28 is moved to painting position. Also as the brush moves from painting positionback to norme] position, ajpredetermined amount, of markiri'g material is'disc harged upon the brush for the next'succeeding marking operation.

whereby the movement of the cam 22 can be properly controlled to produce the marking and dispensing operations. heretofore. described. The

cam 22 is freelyrotatablymounted upon a suitand 5),, said shaft; H5, in turn, being rotatably mounted-in a-suit- I able bracket I i6,'secured to the lower portion of able shaft H5.(Figures 2, 4,

support Ill. Theshaft H5 has a worm gear II! secured on the end remote from thecam 22,;and meshing with this worm geanis'a suitable worm v H8 which is f xedly secured upon motorshaft die-3.1 and the associated yarn carrier 30 will be constantly rotated. At the same time, the shaft H5 will be rotated but since the cam 22 is loose- 1y mounted therearound', the cam will normally remain stationary. Asa meansfor connecting a shaft l I5 to the cam 22, a suitable disk i 25 is fixedly secured around the shaft il5. Said disk has a plurality of radially disposed spokes or prongs I26 which are adapted to engage a suitable plunger I21 extending from plunger [30in the cam 22.- Especial attention is called to the fact that each of the spokes I23 has abeveled 1 facel26a adjacent the plunger 52'! tothereby insure that the plunger I27 will move betweenthe spokes when it is desired to connect the cam 22 tothe shaft H5. This cam surface i260, is

disposed on the back side of the spokes from the side which engages the plunger I21, and serves 'to permit the plunger to move laterally inward between the spokes instead of being stopped before entering, When the plunger I21 is disposed betweentwo adjacentspokes I25, it forms a tie between'memberlZS and cam member 22 and It is desirable to provide a suitable clutch mechanism When the motor 31 is in operation, the spin- 7 therefore causes the cam 22 to" rotate along'with shaft H5.

By observing Figure 7, itwillbe seen that th'e" plunger I2? is slidably mounted in a second plunger I30, saidplunger I3llin-turn;-being'slid- 5= ably mounted in the cam 22. -A- suitablecom pression spring lSI norm ally forces the plunger" I 2 Plateral-ly from theplunger I Swat all times; but when the plunger= I ZI'isddextended position" it"will not normally project into the-path of the spoke s I ZG-unless the plunger-I3fihasbeenmoved laterally from its normalpositionas'sh'ownin- Figure '7. The plungers I21 and lBEl-are held in normal position, that is in the'position-where-the endof plunger I21 will not contact spokesIZt-bw any suitable means such as compression spring- I35 disposed around the plunger I30v Theplungers I21 and' I3ilare' pushed to-theleft in Figures 4 and '7 by means-of-a suitable-L-- shaped lever I36. This lever'I36 'hasits-upper'-' end pivotally mounted as at- I31 in a-brack'et- I38, said bracket I3B-"being;securedto the lower portion of support H]; Fixedly-secured to lever l36 as at I3! is an L-shapedrod I39? said rod I39-having its free endpivotally seemed as at" 25 I40 to a lower end of vertically disposed shaft I4I. This shaft I 4| is slidably mounted in=the supporting stand Ill and projects -vertically'up-'- wardly therethrough; On the upper end of shaft- MI is a button or hand rest M4 upon which downward pressure is applied when it is desired to rotatethe lower end of lever I36 to the left in Figure 4 and thereby push the plunger-"I21 between two adjacent spokes I26, thereby" connecting the cam 22 to the driving shaftllfi: A"

mit the plunger IE! to remain out of the pathof spokes I26.

When the hand rest I44 is depressed, however, the lower end of-lever I36' (Figurei) i will be pushed inwardl to push plungers I21 and.l30' farther into the cam 22. If the spoke I2B'ha'pe 45 pens to be disposed in the path of the plunger I27 when such pressure is-applied to thefh'and rest, the spring 21o will be depressedwhile' the plunger I 39 continues to move inwardly. Since. the rotation of the wheel I25'is relatively fast it is only necessary for pressure to be appliedvto the hand rest I44 for a veryshort period of time until th spoke I26 will pass by the engaging; plunger I27 sufficiently to permit spring IZTd to force the same to dotted line positionbetween the spokes.

Upon the engagement of' theplunger IZT'by. one of the spokes I25, the cam 22 "together with. the plungers I27 and 'I30will bebodilyjrotated'l about shaft I55. As this plunger I30"rotates a slight amount from the position shown infig e ures 4, 5 and 7, the head of said plunger-will." engage a suitable camsurface I50 which surface is cut the face of bracket I38. In other words,

by exerting manual pressure on' the 'hand'rest' for a very short interval of time,:the plunger I30 1' will be bodily rotated about shaft H5 until *tlie. head of the plunger moves into engagement with. the cam surface I50; and this cam suriace'will." positively hold the plunger in advanced position for almost a complete revolution of shaft'll'li.

When a complete revolution of cam 2'2"has been made, "the head of plunger I36 willagain slide into a notch I5I out inthe vertical face of bracket lifat The handpressure'willhave been reissue-e4 relieved from the handrest during. the rotation ofthe cam and therefore the lower' end' 1 of the" lever I3 6*wil1 be'ret'racted to normal position by the force of spring "-I 35; consequently plunger I11 will 'be disposed in anon-obstructing" position relative--11; wheel I 25 whenthe plunger" I30 *com: ple'tes this revolution and again enters the notch" It istherefore seen' that this improved clutch:

' mechanism makes itpossible for avery. slight pressure' on the' hand rest to connect the 'cam 22 to "its driving shaftIIBl" The hand rest may" be almost immediately "released-because the 'cam' surface- I 50 will -maintain-the-plungers- I'2Iand" I 30 '-'=in ran extendedposi-tion for the-remainder of the revolution-L Upon completionof'a revolu= tion the =plilngers will automatically free themselvesnf-r'om spokes I 2fii byvirtue of' 'thespri'ng" l35 whieh forees the head of plunger I30 back" ito-normalposition within notch I5I when arev olution' has been completed; and thereby discon== nect c'an zz rrom its driving' shaft I I 5:
