March 1944- M. CASTRICUM DRIER FOR YARNS QR CORDS Filed June 1'7, 1943 ATTORNEY Patente d Mar. 28, 1944 UNITED STATES PATENT OFFICE DRIER FOR YARNS OR CORDS Martin Castricum, Grosse Pointe, Mich, assignor to United States Rubber Company, New York, N. Y., a corporation of New Jersey Application June 17, 1943, Serial No. 491,158

4 Claims.

This invention relates to a drier for yarns or cords and more particularly to an extremely simple tube construction for rapidlydrying yarns or cords which are being advanced under tension.

The drier f the present invention may be employed in various fields todry strands under tension before they are wound into a package, but has been developed more particularly for use in connection with the apparatus of the Hansen and Benson U. S. application, Serial No. 491,160, filed June 1'7, 1943, Method of and apparatus for treating yarn or cord.

In treating yarns or cords in accordance with the application just mentioned; it is important to dry the wet and highly stretched yarns or cords under tension as they are advanced towards the winding or packaging mechanism so that they will be dry by the time they reach the package forming position, and it is important to dry such yarns or cords as rapidly as can be done without scorchin them since the speed with which the yarns or cords can be treated upon such apparatus depends upon the speed of the drying operation.

The primary feature of the present invention resides in a long heated tube having a hard smooth outer surface over which yarns or cords to be dried may slide freely in direct contact with th surface of the tube as they travel lengthwise thereof. Direct contact of the yarns or cords with the heated surface of the tube throughout its length is secured by causing such yarns or cords to travel in a long spiral path about the tube so that their tension will "hold the spirals in contact with the tube surface.

One important advantage of the present type of drier resides in the construction whereby it is free from operating parts, and another advantage resides in the fact that the tube may be many feet long so that each yarn or cord will travel in direct contact with its hot surface throughout a distance of many feet to dry it rapidly. Another advantage of the present construction resides in the fact that it is relatively easy to maintain the tube at any desired temperature and to control the tension of the yarns or cords during the drying operation.

The above and other features of the present invention will be more fully understood from the [following description when read in connection with the accompanying drawing wherein:

Fig. l. is a side elevation of a drier for yarns or cords, constructed in accordance with the present invention.

Fig. 2 is a similar view on a larger scale with parts in section and with the central portion of the tube broken away, and;

Fig. 3 is a section taken on the line 3-3 of Fig. 2.

'The drying tube In may vary in diameter from several inches to many inches depending largely upon the number of yarns or cords that are to be advanced simultaneously along is surface and the length of the tube may be ten, twenty or more feet depending upon the speed at which it is desired to dry the yarns or cords. It is apparent that the greater the length of the tube the quicker the yarns or cords traveling lengthwise thereof in contact with its surface can be dried without subjecting them to such high temperatures that they are likely to be charred or otherwise injured by the heat of the tube.

The tube i0 is preferably made of metal such as steel having a ground surface which is plated and polished so that the yarns or cords will slide smoothly upon its surface, and so that the surface will not rust or corrode from the moisture 0 the wet strands.

The tube Ill may be heated by various mean but is preferably heated by steam, for tempera tures above the boiling point, and by hot wate for temperatures below the boiling point. In mo: cases it will be desirable to heat the tube to temperature well above the boiling point by th use of super-heated steam,jand in this case th tube Ill will need to be strongly constructed an capable of confining steam under considerabl. pressure. The tube i0 may therefore be given the construction illustrated in Fig. 2 wherein i will be seen that the long tube proper II has it ends closed with the metal heads l2 and I3 whiclare fitted within the ends of the tube II and welded in place. The tube I0 is shown as provided with the steam inletpipe l4 threaded centrally through the head l2, and with the outlet pipe I5 leading from the lower wall of the tube I l adjacent the head [3 and through which steam and water that condenses out of the steam may escape.

In order that water which condenses inside the tube may drain therefrom, it is desirable to support the tube III in aslightly inclined position as shown in Fig. 1 so that the outlet pipe l5 will extend downwardly from the lowest portion of the tube. The tube I0 is therefore provided at its opposite ends with the supporting rods IS, the lower ends of which are bent laterally to extend into drill holes formed in the heads l2 and I3 and are preferably welded therein, and the upper ends of these rods are threaded as shown to recelve the turn buckles II which cooperate with the rods N to suspend the tube II at the desired inclination from the overhead structureor supporting frame I! having the transverse bars 20 to which the rods II are secured.

The yamsor cords 2| to be dried may be supplied to the tube In in a wet condition from any yarn or cord treating mechanism, not shown, and

advanced lengthwise of the tube in the direction.

indicated by the arrow. These yarns or cords may be advanced under controlled tension by any suitable means.

It is desirable to maintain the yarns or cords in spaced relation to each other throughout the drying operation and to cause them to press firmly against the smooth outer surface of the the axis of the drum III as best shown in Fig. 3.

A similar disc 22 is provided at the opposite end of the tube Ill and is mounted upon the steam inlet pipe I.

The arrangement is such that the concentrically disposed apertures 25 serve to hold the yarns or cords 2| in spaced relation to each other as they approach the tube II and are delivered thereto, and the desired long spiral movement is imparted to these yarns or cords as they travel along the tube by winding them around the tube, say for one complete revolution as shown, from one guide disc 22 to the other. construction without moving parts the yarns or cords 2| are maintained in spaced relation to each other and in direction contact with the surface of the tube lflthroughout their travel along the tube, and due to their contact with the hot surface of the tube throughout its length they will be By this simple Having thus described my invention, what I claim and desire to protect by Letters Patent is:

1. A drier comprising a long heated tube having a hard smooth outer surface over which yarns or 5 cords will slide freely, guide means at one end of the tube for guiding yams or cords to the tube v and at the opposite end of the tube for guiding them therefrom so that when the yarns or cords are drawn forward under tension they will contact the outer surface of the tube and travel lengthwise thereof in long spiral paths in drying engagement with the tube.

2. A drier comprising a tube having a hard smooth outer surface over which yarns or cords will slide, means for supplyin a heating fluid to the interior of the tube, guide means at one end of the tube for guiding yarns or cords to the tube and at the opposite end of the tube for guiding the yarns or cords therefrom so that when they are drawn forward under tension they will contact the outer surface of the tubeand travel lengthwise thereof in long spiral paths in drying engagement with the tube.

3. A drier comprising a heated tube having a hard smooth outer surface over which yarns or cords will slide, guides at the opposite ends of the tube disposed concentrically about the tube axis and adapted to guide a number of spaced yarns or cords to one end of the tube and from its other end so that when they are advanced under tension lengthwise of the tube they will contact its outer surface and travel in long spiral paths in drying engagement with the tube.

4. A drier comprising a metal tube adapted to have a heating medium circulated therethrough, and formed with a smooth outer surface over which yarns or cords will slide, guide means supported by the tube at its ends in concentric relation about the tube axis and adapted to guide a 40 number of spaced yarns or cords to one end of the.

tube and from its other end so that when they are advanced under tension lengthwise of the tube they will contact its outer surface and travel in long spiral paths in drying. engagement with the dried rapidly so that upon leaving the discharge tube.

end of the tube they will be practically free of moisture.
