This invention relates to a machine for condi tioning textile ?bres such as packages of yarn in the form of bobbins, cops and the like. In the textile art, thread on the bobbin is treated with 5 a solution, with certain ingredients therein, in order to set the twist in the thread before it is used for other purposes. In machines heretofore used for moistening or conditioning yarn it has been necessary to employ machinery which occu 10 pied considerable floor space so that all portions of the packages would be subjected to this treat ing solution. Other machines have been provided which did not occupy a great deal of ?oor space but yet the means for turning the packages while 15 being subjected to the treating solution entailed mechanism which has not proven to be efficient and practical. It is therefore, an object of this invention to provide an apparatus which has means for turn 20 ing the packages while the same are being sub jected to a spray of the treating solution so that all portions thereof may be equally treated. This turning means comprises a pair of beveled baf fies or guards which are oppositely disposed above 25 a conveyor belt and in the path of travel of the packages. As the conveyor passes beneath these guards or ba?les the packages contact these guards and are caused to creep laterally of the conveyor (Cl. 68-—205) It is a further object of this invention to pro vide an apparatus for treating yarn comprising a conveyor upon which the bobbins are placed for treatment with means for rotating the conveyor beneath a plurality of thin sheet sprays which are 5 directed downwardly upon the packages from spaced nozzles. These nozzles are of a peculiar design which spray the liquid therefrom in a sheet formation so that at the point where the liquid strikes the top of the conveyor the longest side 10 of the sheet will be disposed at right angles to the path of travel of the conveyor. By providing this nozzle it is evident that all of the packages which’are disposed on the conveyor will be treat ed with an equal amount of solution. In the con- .15 ventional nozzles the cross sectional area of the spray at the point of contact with the conveyor is circular in shape; consequently, when the pack ages pass beneath this spray those packages which traverse the central portion of this circular 20 spray will be subjected to more liquid than those which traverse the outer edge portions of the spray. 'I have arranged a plurality of my in proved nozzles in alinement directly above the conveyor belt so that as many of the same may 25 be used as desired to vary the quantity of solu tion which is sprayed upon the packages as they pass beneath the spray nozzles. Some of the objects of the invention having been stated, other objects will appear in the de scription hereinafter following, when taken in connection with the accompanying drawings, in cause the bobbins thereon to be rotated so as to which: Figure 1 is an elevation of the invention show expose all partions of their surfaces to the down ing portions of the liquid container broken away; wardly projected treating solution. Figure 2 is an elevation looking at the oppo It is a further object of this invention to pro vide an apparatus of a class described which has site side of Figure 1; Figure 3 is a plan View of the invention; a conveyor belt formed substantially of ?at slats Figure 4 is an elevation looking at the left with the upper surfaces thereof occupying the 40 same plane. The edges of each of the slats have hand end of Figures 1 and 3; Figure 5 is a longitudinal, sectional view taken a slight rim portion integral therewith which forms a dished portion in the central portion' along the line 5-5 in Figure 3; thereof for holding some of the treating solution Figure 6 is an enlarged sectional view, showing so that the lower side of the package as it is certain portions thereof in elevation and taken 45 turned thereon will absorb the solution in this through a portion of the spray head shown in Figure 5; dished portion. At the same time the upper por tion of the package is absorbing the downwardly Figure 7 is an enlarged sectional plan view directed spray. In other words, the lower side taken along the line 1-1 in Figure 6 showing a of the package is absorbing the liquid which is detail of my improved nozzle; sprayed onto the slats while the upper portion Figure 8 is a sectional view through the by of the package is absorbing the spray which is pass check valve shown in the lower left-hand directed downwardly from the nozzles. The pack portion of Figure 5 which works in connection ages are turned by the side guards, which creep with the pump mechanism; the packages from one side of the conveyor to the Figure 9 is an inverted isometric view of a por 55 other. tion of a slightly modi?ed form of conveyor belt; simultaneously as the treating solution is being It is evident that this lateral creeping motion of the packages, ?rst from one side of the conveyor and then to the other, will 30 sprayed thereon. 30 35 40 45 55 2 2,158,046 Referring more speci?cally to the drawings, the numeral l9 denotes the back end frame support which has resting on the upper portion thereof baffles 4'! and 48 are placed in a staggered relation to each other so that all of the bobbins will be al lowed to creep and roll transversely of the con veyor until the center line of the spray head has been reached and then the other ba?le 41 will horizontally disposed angle‘ members II and i2, move these same bobbins transversely in the op Figure 10 is an isometric view showing the top portion of one of the slats used in Figure 9. the front end of said angle members being secured to the upper portion of inclined angle supports !3 and I4 respectively. Secured to the inclined 10 members I3 and I4 and near the lowermost por tion thereof are angle struts 15 which project rearwardly of the machine and are secured to the lowermost portion of 7 support It). Also se cured to- the lowermost portion of inclined mem 15 bers l3 and I4 are shoes l6, said shoes having solts l8 therein into» which bearings 19 are adapted to slide. These bearings house the ends of shaft 20 upon which sprockets 2| are ?xedly secured. The positions of bearings l9 are adjusted by 20 means of set screws 22 which are threadably se cured in outstanding lugs 22a in the upper end of brackets 16 with the lower ends of said screws contacting the upper‘ side of the bearings l9. Suitable sprocket chains 24 are adapted to be 25 mounted upon the sprockets 2| and 2B, and upon these sprocket chains cross bars 25 and 25a. are secured for supporting bobbins 26 and conveying them to the position where they are to be treated. The conveyor is broadly indicated by reference 30 character 21. The cross pieces 25a are higher than the pieces 25 so that a predetermined amount ofpackages will be collected and con veyed upwardly. The sprockets 28 are ?xedly secured on cross shaft 29, said shaft having its 35 ends rotatably mounted in the inclined members l3 and I4. These inclined members l3 and 14 are spaced apart from each other by means of struts 39. ‘ In order to provide means for holding a supply 4.0 of'bobbins or packages 26, a suitable hopper 3!‘ has been mounted upon the top of inclined mem bers l3 and H!‘ with its sides surrounding the top side of the conveyor. When the bobbins are placed in the hopper 3| as shown in Figure 45 5, the high cross pieces 25a will collect a portion thereof and convey them towards the top of the conveyor where they will be delivered-to a hori zontally disposed conveyor 33. This conveyor comprises a plurality of horizon tally disposed rods 34 which are secured between‘ 50 sprocket chains 35. These chains, in turn, are rotatably mounted upon sprockets 31 and 38 which are ?xedly secured upon shafts 39 and 40 respectively. posite direction until they have passed out from beneath the spray. This creeping or shuffling of the bobbins causes all portions thereof to be 10 turned and exposed to the spray. The conveyor belt 33 is held in taut position by means of the bearings 50 whichare secured to the outside of angle members II and I2. The ends of the shaft 49 are rotatably mounted in blocks 5! which blocks are slidably mounted in 15 slots 5lla.in these bearings. Set screws 52 nor Vmally contact these blocks to hold the shaft 49 in the desired position so that the belt will re main taut. In order to provide means for driving the con 20 veyor belts 2‘! and 33, a suitable motor 55 has been mounted upon bracket 56 which extends out from the framework of the apparatus. This mo tor has a motor shaft 51 and a pulley 58 upon which a. belt 59 is mounted. This belt is also 25 mounted upon a larger pulley 5|! which is secured to the end of a shaft 6!. The shaft 6| is rotat~ ably mounted in inclined angle members i3 and I4 and has secured on the other end thereof a pinion 62 which meshes with a larger gear 63, 30 said gear 63 being ?xedly secured on shaft 29. Upon rotation of the motor shaft 51, counter clockwise motion is imparted to the shaft 29 through the members just described, to cause the conveyor belt 21 to deliver predetermined quan titles of bobbins 25 to the conveyor 33. The shaft 29 also has a sprocket 64 secured thereon upon which is mounted a sprocket chain 65. This chain is also mounted upon a second sprocket 65 which is ?xedly mounted upon the 40 shaft 39. The counter-clockwise motion of shaft 29 will therefore be imparted to the shaft 39 which in turn will cause the conveyor belt 33 to transport the bobbins toward the rear of the machine. 4:5 Secured between the upper sidewall portions 46 and 45 is a pair of rods 19 upon which is se cured a bracket ‘II which supports a T-shaped pipe ?tting 12, into which liquid is delivered from hose 13. Leading from opposed ends of member 50 12 are suitable short. pipes 15 which have the other ends thereof connected to through valves 16. (Figures 5 and 6.) Nozzles 11 are connected The ends of the shafts 39 and 49 . to the lower portion of the valves 16 and these 55 are rotatably mounted‘ in suitable bearings se~ cured to the horizontal angle members I l and [2, The sides of the conveyor 33 are enclosed by side walls 45 and 46 mounted upon the angle members II and I2 respectively. These sides 60 have beveled baf?es 41 and 48 secured thereto with the lower end of the baffles extending over the top of the conveyor belt 33. When the in clined conveyor 21 delivers the packages to the horizontal conveyor 33 as shown in Figure 3, the 65 movement of conveyor 33 will cause the bobbins to ?rst contact the ba?ie 48. Upon further move ment of the conveyor the bobbins will be caused to creep and roll towards the observer in Figure 3 at the same time the spray will be projected downwardly thereon from the nozzles. The baffle 41, which is secured on the opposed side of the conveyor, will then be contacted by the bobbins on this side of the conveyor thereby causing the whole batch to creep and roll away from the ob server in Figure 3. It will be noted that the nozzles have an ori?ce 18 in the lower portion thereof through which the spray is forced. (Fig ure '7.) It will be noted that the lower portion of the nozzles have an elongated groove 19 which is diametrically disposed relative to the ori?ce 18. Also, on the inside of the nozzle are diamet 60 rically disposed grooves 80 which intersect the upper portion of the ori?ce. The liquid moves downwardly through the ori?ce ‘l8 and due to the grooves 19 and 80 the spray is caused to assume substantially a rectangular shape at the con 65 veyor thereby maintaining an even width of spray across the conveyor. ‘This will insure that all portions of the conveyor as it passes beneath this spray will be subjected to an equal amount 70 of treating solution. As heretofore stated, if the spray were circular in shape at the point where it contacted the conveyor then the portions of the conveyor which pass beneath the central por tion of this circular area will be subjected to 75 3 2,163,046 more treating solution than those portions which pass through the outer edges thereof. Each of the valves ‘I6 has leading therefrom another pipe 85 which is connected to a spray head 86, said head being identical in all respects to the spray head 'I'I recently described. All of the spray heads such as 11 and 86 are placed in alinement with each other substantially over the center line of the conveyor so that variable quan 10 tities of liquid may be delivered to the bobbins on the conveyor. If desired, by means of the wheels 8'! of the valves ‘I6 the ports 98 which lead to the nozzles 11 may be closed and only the outer spray heads 89 used. The T-?tting ‘I2 has a gauge 99 secured thereto 15 which registers the amount of pressure set up in spray heads and the delivery hose 13. This de livery hose has its lower end connected to the outlet pipe 9| of pump 92, said pump being driven 20 by the motor shaft 51 simultaneously with the driving of the conveyors. The pump has an inlet pipe 93 leading thereto, to which is secured a hose 94. This hose leads to the lower portion of container‘ 95 in which the treating solution is 25 placed. When the motor is in operation the pump draws the solution from the container 95 through the pump 92, hose ‘I3, and forces it out through the spray heads ‘I1 and 89 onto the bob bins 26 which are disposed upon the conveyor 33. 30 If for any reason, it is desired to use only the outer spray heads 86 then the ports 88 are closed. Due to the closing of the ports 88, but at the same time maintaining the same speed of the motor and pumps, a pressure will naturally be 35 built up in the hose 13. In order to neutralize this excess pressure and prevent more solution from passing through the nozzles which are then in use, a suitable by-pass pipe 91 has been pro vided which has one end thereof connected to 40 the outlet pipe 9| and its other end connected to the inlet pipe 93. Disposed in this by-pass is a spring check valve 98 which has a ball 99 there in‘ normally closing a port I99. A spring I9I normally presses the ball to a closed position, 45 (Figure 8) , but due to the adjustment of the pres sure on spring I9I liquid will be allowed to ?ow through the port I99 and into the intake side of the pipe line when an excessive pressure is built up in the hose ‘I3. The point at which liquid will be caused to ?ow through the port I99, is varied by means of cap 98a which is threadably secured on the end of the check valve casing 98 to vary the amount of pressure exerted upon the spring I 9| and ball 99. The eXcess liquid which is sprayed upon the 55 bobbins and the conveyor is caught by a suitable inclined pan I93 which is disposed directly be 50 neath the conveyor belt 33. This pan has an out let I94 in the side portion thereof at a point 60 where the excess liquid will be delivered to the opening I95 in the top of container 95. This opening has a strainer I96 disposed therein for removing any objectionable matter from the liquid. Figures 9 and 10 show a slightly modi?ed 65 form of conveyor belt which may be used to re place conveyor 33. This conveyor comprises a plurality of slats I98 which have raised ribs I98a on the top surface thereof thereby forming a dished channel I98b‘ for holding a limited supply of the treating fluid from the nozzles. The pack ages of yarn which rest upon these slats will ab sorb the treating ?uid in these channels. These slats are secured to suitable links I99 of a sprocket chain in the manner shown in Figure 9. In the drawings and speci?cation there has been set forth a preferred embodiment of the invention, and although speci?c terms are em ployed, they are used in a generic and descriptive sense only, and not for purposes of limitation, the scope of the invention being set forth in the appended claims.
