paratus, and more particularly to apparatus for cooling, washing or otherwise treating the surface of a wire or other strand with a liquid medium.

Where a hot wire is to be cooled rapidly and thoroughly, orwherethe surface of a strand is to be thoroughly and rapidly washed or rinsed or pickled or otherwise subjected to some action of a liquid medium, it is desirable to cause as much as possible ofagiven quantity of the liquid in question to come into contact with the strand in order that the liquid may be efliciently effective for its purpose and not be wasted itself or require wasted energy to circulate unused liquid. For example, in the manufacture of tinned copper wire, the wire is coated with tin by being drawn through a bath of molten tin and emerges therefrom hot and with a hot coating. To cool both the coating and the wire inside of it for further manufacturing procedures or to harden the coating sufllciently to permit the coated wire to be wound on a spool or reel for stora e, requires the intimate contact of a relatively considerable quantity of cold water with the surface of the hot, coated wire.

An object of the present invention is to provide a simple, reliable and efliciently operating apparatus or device for apply n to a strand passing longitudinally therethrough a liquid in such fashion as to effectively assure contact of the surface of the strand with a maximum proporing formed with a coaxial bore to pass a strand moving axially through the channel to be subjected to the action of the helically turbulently moving liquid therein.

As herein disclosed. the, illustrative embodiment of the invention comprises an elongated tubular body and a parallelopipedal head joined thereto. The head, generally. indicated at In, for convenience of manufacture consists of two rectangular blocks II and I2, held together by screws l3, and is formed with an annularly conoidal chamber H, the inner wall of which forms on its outer surface a conical entrance IS. The tubular body,'general1y indicated at l6, comprises a main body tube ll inset at one end into the block l2 coaxially with the chamber l4. Telescoped snugly over the tube I1 is a rotatably adjustable cover tube l8. A short tube I9 is telescoped and secured in the left end of the tube H. The left ends of this tube l9 and of the tube I! are chamfered as at 20 to continue the taper of the outer wall of the chamber H to the diameter of the inside tube l9. After a short, parallel-sided throat 2| the tube I9 is chamfered out as at 22 to the diameter of the tube H. The inner wall of the chamber l4 extends as a cylindrical stem 23 into the chamfer cone 20 and is formed with a coaxial bore 24 communicating between the conical entrance l5 and the chamfer cone 20. The chamber M, the entrance IS, the bore 24, the cone 2., the throat 2| and the chamfer cone 22 are all coaxial with each other and with the tubes l1 and I8. A plurality of choke tubes 25 (three in the particular device illustrated) is mounted inside the tube II at intervals along the length thereof. Such a choke tube 25 is a short length of tubing telescoped snugly with the tube l1 and secured in place, e. g. by sweating with solder. The end toward the head is chamfered out on a relatively long taper as at 26, best shown in Fig. 4, and the bther end is squared oi! as at 21. The tube l1 and the tubes 25 are formed with a long slot it along its top, and the cover tube is is formed with a matchinsly shaped and dimensioned slot ll, ordinarily not coincident with the slot ll. The right hand end ofthetube II is secured in a T fitting 30 having a plug 8i with a smell central bore 32 therein coaxial with the tube l1. Thedownwardlydirectedstemu oftheT may be connected to any suitable waste means or liquid recovery means (not shown). Within the head II, a diaphragm it extends across the chamber ll and is provided with a ring of apertures 35, each formed by cutting free and bending out to the right flaps ll. These iisps are rigid and stand out at about a half right angle to the right (Fig. 4) from the diaphrasm. all facing the same way as shown best in Pig. 6. Two liquid inlet pipes, 31 and 31 respectively, enter the chamber it from opposite sides, preferably from above and below as shown. The upper pipe 31 is provided with a shut oi! valve 80. while the lower pipe 38 has a three-way valve 4|. These valves are connected to suitable liquid supply means (not shown). The valve ll also has a waste outlet ll by means of which the whole device may be drained when desired. The pipes 31 and SI not only enter the chamber M at opposite sides but also enter it tangentially as shown in Fig. 8.

In the particular case of tin coated wire. now under consideration, it is desired to have the coldest liquid, water in this case, meet the hot wire first to chill and set the soft tin at once. Hence the water and the wire are not run in counter-current directions. The hot wire is led into the device from a tinning means 42 and a wiping means 43, into the entrance I! and the bore 24, axially through the tube "and the chokes l9 and 25, and out through the bore 82 in the plug II to some advancing means (not shown). Water under pressure enters the chamber it through the

tangential pipes

31 and 38, whirls around and passes through the openings 3! and along the spirally directed flaps a to continue in a helically whirling course through the cone II and into contact with the hot wire in the throat 2| in a state of turbulence which causes a major portion at least of the water to make actual contact with the wire while passing through the throat 2i and over the enlarging ramp of the chamfer cone 2! and on through the tube H. The whirling effect may die out as ass-mas Asdescribed, the tinned wireto be chilled is the water and wire pass along: but at the first of the choke tubes 25 the flow of water is speeded up by the constriction and then in breaking out creasing from left to right along the dmction of liquid flow. This feature increases the crosssectional area of the liquid passage from left to night and so helps to slow down the velocity of v the liquid flow as it approaches the outlet 33.

However, the primary purpose of the slot 28 is to render it easily and conveniently possible to thread a strand through the apparatus. By turning the outer tube or sleeve 18 until the slot 29 coincides with the slot 28, the interior of the tube i1 is made accessible for threading a strand.

run through the-apparatus in the same direction that the water flows. In another case, e. g. were the wire to be pickled, for example, it might be preferred to run the strand in the opposite direction in order to have the flow counter-current to the motion of the strand. Again, if the case were of a porous strand, e. g. a textile strand, or a wire sheathed in paper pulp or served with textile threads and to be impregnated with some liquid material, the strand might be run from left to right, J. e. with the liquid flow, to lessen the scrubbing effect of the liquid on its surface;

while if the strand were to have a coating dissolved from its surface, the strand would be run against the current flow to increase the mechanical effectiveness of the liquid.

While the apparatus is shown with two liquid supply pipes 31 and II, it is not necessarily so limited. The pipe 31, for example, might be omitted, or there could be more than two entering the chamber ll tangentially.
