( Cl.V 68;2( 6) lllaims- 1 rIrhis. invention relates to improvements for impregnating packages of lamentary `material, particularly annular wound packages of` artificial or. natural lamentary. material which are ob tained by' means of centrifugal spinning f and twisting. potsfsuch packagesl being. generally .re-1 ferred to as cakes whichterm will be used. here.- inafter.

I i-,hfis' an objectv of the rinvention to provide a novel andimproved form ofv liquid treating apparatus capable of treating a plurality of cakes of, articial iilarnentaryA material at once, of applying'th liquid simultaneouslyto both the inside and the outside of the cakesand ofv yielding rapid and uniformv impregnation thereof. IFur-v ther objects. ofthe invention will be apparent from the, drawing. and the. description thereof hereinafter. l t Y Y "In the. drawing, illustrative of` the invention, Figure l is a side elevationwith parts cut away, ofthe device, ofthe invention,

Figures. 1 and 2 show. thel device without the cakesof lamentary material in position thereon.` Essentially, the devicelcomprises an vupright standard 2r for supporting two horizontal tubes 3, and 4, preferably superimposed in a vertical plane. The upper tube Il. is provided with a plurality of-` spray headsr` along. its-under surface, each spray. head conmrising a single, or preferably, af pluralityA of orices, The., lower tube is also provided witha corresponding set of spray heads 5, preferably. alongits lower surface and; aiiange @is secured to the lower tube 3 just beyond the spray. heads 5 in orderv to position;Y the l cakes totbe placed thereonv adjacentv the Sprays A single wnduitmay. serve t Connect thesupplyof liquid tothe several spraysin each of the rods.

drives a large sprocket I6 which is. rotatably niounted. upon a cylindrical portion ofthe lower. tube 3 Yjust back of the 'flange B securedl thereto'. This large sprocket I Ais provided with a lsocket I1 which is adapted toreceive onek end of a rod I8- byQmeansof which an operator may insert the ucakes to be. treated into operativel position within the device. The lowertube 3 has its"upv perfsurface indented't'o provide, a longitudinal guideway I3. for the rod `18.130 lighten the. burden ofthe operatorinloading and unloading. the del vice with the cakes to Abe treated.l A trough 2l),

Theoperatorthereupon pushes all ofthe cakes, which now-embrace. both thelower spray tube'3 and the rod I8, up against the flangef, opens the valves l0 controlling the liquidfsu'pply line, andswitches on the motor. l I. Uponlconipletion of one cir-.more rotations ofthe rod 'f8 aboutlthe tube 3, the operator.. closes the valve I0 and switches the motor Il 01T, unloads the cakes andrepeats. the cycle for. subsequent batches.

Figures 4 and 5.v show a modiedjforin of lower spray tubeA 22 in which the flange 2,3 (analogous to ange 64 of Figures 1 and 2)Y secured thereto is slotted at 24 and a sloping trough like guideway 25 isA secured to the tube to form a substantially continuous guiding surface from the grooved upper surface 26A of the spraytube to the socket I7 whenV it is ina position directly above the lower tube. Byy such a modication, theoperator may simply. stop the socket in its uppermost position and both unloading and reloading are greatly facilitated by 'means of the guideway 25 fromY the socket` to the lower tube.

In a preferred embodiment, the device is pro-v vided with electrical connections for automatically rstopping 'rotation of they motor and closing the valve tothe liquid supply when they socket `I'l dfinies' its @Perma position- TO. accbmplish this result, the valve ID in the fluid supply line may be a solenoidor thrustor-operated valve and a solenoid-operated brake may be provided upon the shaft of the motor. In addition, a switch 21 is provided whose two terminals 28 and 29 are adapted to be closed by contact with the outer periphery of the socket l1 at its uppermost position (see Figure l). The arrangement is diagrammatically represented in Figure 3, Thel closing of this switch 21 by the socket I1 causes mentary material comprising a longitudinal memthe main switch 30 connecting the motor and valve circuit to the power supply 3| to be opened, such as by the action of a solenoid 33 in the circuit with the socket switch 21 which retracts a core 34 and thereby permits the main switch 30 to spring open to the position shown in Figure 3. Assuming that the main switch 30 has thus been opened and a fresh batch of cakes has been loaded into the device, the operator starts the machine by closing the main switch 3G by hand or by a foot-operated lever and holding it closed until the socket I1 has passed out of contact with the terminals of the auxiliary switch 21. Closing of the main switch effects opening of the valve l0, operation of the motor H, and a release of the brake 35 such as by operating a solenoid to retract suitable brake shoes from a brake drum on the shaft of the motor in opposition to springs normally tending to cause breaking. Upon completion of a single rotation of the socket l1, the auxiliary switch 21 is closed automatically by socket l1, thereby opening the main switch 30 which causes closing of the valve lll, and braking of the motor shaft.

1f desired, the valve I0. may be replaced by a measuring pump which may be operated by an electric motor automatically controlled in the same manner as the valve lll to start delivery of the liquid upon starting rotation of the cake supporting rod and to stop delivery upon each complete rotation of the rod.

While the device of the invention may be employed to apply any liquid to wound lamentary cakes, such as for bleaching, dyeing, etc., it is particularly adapted to the application of lubricating, softening, and conditioning media or solutions thereof, especially in organic solvents having low surface tension. The device has provision for applying the medium simultaneously from both inside and outside the cakes while moving the cakes relative to the liquid sprays. The result is an efjcient, rapid and uniform impregnation of the cakes with a minimum of labor expenditure, power consumption and loss of materiaL While preferred embodiments of the invention have been disclosed, the description is intended to be illustrative only, and it is to be understood that changes and variations may be made without departing from the spirit and scope of the invention as defined by the appended claims.
