DRYING APPARATUS.

SFEGIFKUATION forming part of Letters Patent No. 675,606, dated June 4, 1901.

Application filed January 19, 1900r fiei'ial No. 1,967. No model.)

To all whom, it may concern:

Be it known that I, GEORGE A. MUENZEN- HATER, a citizen of the United States, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented a certain new and useful Improvement in Drying Apparatus, of which the following is a specification.

My invention relates to drying apparatus especially adapted for drying, or for drying and polishing, or for drying, polishing, and finishing cord, twine, yarn, cordage, rope, and the like.

For the sake of convenience and brevity I shall hereinafter use the term cord as embracing also twine, yarn, cordage, rope, or similar articles.

In finishing, polishing, and drying cord it is customary to pass the cord through a bath of suitable sizing material to coat the cord to admit of its being finished and polished. It has been customary heretofore after the cord leaves the sizing-bath to pass and repass the same over a pair of interiorly-steam-heated cylinders and to depend upon the heat conveyed from the cylinders to the cord for effooting the drying operation. This mode of drying results in forming a crust of the sizing material upon the outside of the cord before the inside of the cord has become properly dried and results in insufficient drying of the core of the cord. It also results in the fre quent excessive heating and scorching of the cord. The old mode also presents an apparatus in which the drying of the cord is attempted to be accomplished by the mere heating of the cord, resulting in the objections above mentioned, and which also produces a product which after it leaves the machine and is rolled into balls or upon bobbins or spools ready for storage or shipment undergoes a sweating process injurious to the cord, resulting from the ineffectual or insufficient drying of the core of the cord by the objectionable mode of drying pursued, which, as stated, forms a crustation upon the outside of the cord while the core of the cord is still damp, the mere heat from the cylinders being ineffectual to properly dry the core and the crustation serving to retain the moisture afterward gradually absorbed by the entire ball, bobbin, or spool of cord as soon as it cools or while cooling, resulting in the sweating mentioned, thereby injuring the texture and polish of the cord. I obviate these objections by means of myimproved device, in which I pass the cord through a preferably closed drying-chamber and during its passage therethrough subject the same to a current of preferably heated and dry air or other suitable drying medium, which I prefer to pass in a direction reverse to the passage of the cord through the chamber. I also subject the cord to the action of polishing-rolls while the sameisbeingsubjectedtothe action ofthedrying-current, producing an especially highlypolished finish and superior product and avoiding the sweating of the cord hereinbefore mentioned. My improved device also enables the drying operation to be accomplished Within a greatly-reduced space or within a greatly-reduced time when compared to the old modes mentioned.

In my improved device the cord is sub jected to a current of preferably heated drying medium, which acts 011 the cord more in the manner of sun-drying and prevents the crustation on the outside of the cord incident to the old modes of drying by passing the cord over heated cylinders or pipes, which acted more in the nature of baking. The p01- ishing-rolls also acting on the cord at the same time with the current of drying medium incorporate the size into the cord in a more effectual manner, because crustation is prevented, and produce a cord of stronger texture and more pliability, owing to the com bined effect of the simultaneous application of the current of drying medium and the action of the polishing-rolls.

It is a desideratum in cord-making to produce a cord of strong texture, high polish, great pliability, and soft feel, and by means of my improved device I am enabled to obtain all of these in a superior manner.

My improved device also dispenses with the disadvantage of using steam or the like in a moving cylinder or pipes for drying the cord, the use of steam and similar agencies within a moving cylinder or pipes causing corrosion, leakages, and breaks and consequent inconveniences. The cylinders or pipes are also very expensive in construction machine in which the cord to be dried is passed through a preferably closed chamber and therein subjected to a current of drying medium and simultaneously subjected to the action of the polishing means; further, in providing a machine in which the cord to be dried is passed through a preferably closed chamber and therein subjected to a current of drying medium and simultaneously subjected to the action of polishing-rolls acting on the cord while the latter is passing through the chamber and is being dried by being subjected to the current of drying medium; further, in providing a chamber of the character described with suitable guides or guides and deflectors to direct the current of drying mediumto the most desirable points for accomplishing the purpose specified, and, further, in the parts and in the construction, arrangement, and combinations of parts hereinafter more fully described and claimed.

In the-drawings, Figure l is a side elevation of my improved device shown in connection with so much of a cord-finishing machine as may be necessary to illustrate my invention, and Fig. 2 is a front elevation of the same with part of the frame broken away. Fig. 3 is a vertical transverse section taken on the line cc of Fig. 5, and Fig. 4 is a similar view taken on the line y 3 of Fig. 5. Fig. is a vertical longitudinal section taken on the line 22 of Fig. 3 looking toward the'front of the 5"',:machine, but showing the deflectors 62, 66,

and 74. Fig. 6 is a rear elevation of my improved device, partly broken away; and Fig. 7 is aperspective view of the guiding-pins.

A represents the frame of the machine, and B a casing, which may be suitably supported thereby, preferably located within the frame.

0 is the cord or other article to be operated on, which is adapted to be dried and polished by means of my improved device. Before entering the drying-chamber it receives the usual treatment of being sized by passing through one or more sizing-baths, of which I have shown one, D. It proceeds to the sizing-bath in the usual way from a series of bobbins (not shown, because well known) in a series of strands side by side. The cord is v guided into the sizing bath or trough over a roller 1 and under a pair of rollers 2 2 in the trough to cause the cord to be submerged in 65 the size and thence between a pair of rollers 3 4: at the far end of the trough to have the size properly incorporated with the cord and to remove .the surplus size therefrom. It then passes, preferably, over a smoothing-roll 5, suitably driven, adapted to help lay the fibers projecting from the cord and help remove the surplus size and to more evenly spread the size remaining on the cord. The cord then passes a series of guiding-pins G, the latter in one or more rows, and through an opening 7 into the casing or drying-chamber and over a roller 8. Up to the point where the cord is guided by the guiding-pins 6 the mode of operation and treatment of the cord is similar to the modes of operation and treatment now in use, andI make no claim to that part of the apparatus herein shown and described. In the old constructions, however, after leaving the guiding-pins it has been the custom to pass the cord over a pair of interiorly-steam-heated cylinders, the contact of the cord with the steam-heated cylinders being depended upon to dry the cord, which resulted in the objections I have heretofore described, and which objections I obviate by means of my improved device. After the cord leaves the guiding-pins, therefore, I pass the same into a drying-chamber, in which I cause a current of preferably heated air or other drying medium to circulate, as by means of pressure-blower B, preferably in a direction substantially reverse to the general direction in which the cord travels through the chamber. The circulation of the drying medium may also be caused by an exhaustfan. An inlet-opening 9 and outlet-opening 10 are provided for the drying medium.

To support the cord and to cause it to travel properly and to provide as little obstruction as possible to the circulation of the heating-currents, I provide two drums, cylinders, or reels E E, preferably for-med of suitable webs 11, supported by shafts 12 13 and having their peripheries or outer edges preferably provided with suitable slats 14, having spaces 15 between the same to allow a circulation of the drying medium and to provide as little contact as possible between the drums, cylinders or reels, and the cord. The slats thus form the outer edges or peripheries of a drum, cylinder, or reel. It is obvious that true cylinders closed at their peripheries may also be employed without departing from the spirit of my invention.

7 For convenience and brevity I shall here inafter refer to the cord-supporting agency namely, the drum, cylinder, or reel as a drum.

The shafts 12 and 13 are mounted in bearings 16 and 17, supported by the frame, and may, if desired, be made adjustable to provide track for the cord as in a manner similar to the adjustment for the polishingroll bearings hereinafter described. The strands of cord after they pass from the bobbins and through the sizing-baths pass, as stated, through an opening 7 and thence under the drum E, upwardly over the drum E, downwardly under the drum E, and again upwardly, so as to pass and repass the drums the desired number of times, until after their last downward passage they pass about the under side of the drum E once more, thence over a roller 18, thence over the upper side of the drum E, and through an egress-opening 19 in the drying-chamber, from whence they are fed past guiding pins 6 and onto bobbins in the usual way. The roller 18 is preferably a short roller at the egress end of the frame of about the length of the egress-opening 19 and may be supported in suitable bearings 20. The drum E is preferably driven by a suitable pulley or gear, and the drum E preferably receives its motion from the cord itself taking about the two drums. The cord is caused to pass progressively diagonally from the receiving end of the cylinders to the discharge end thereof. Suitable polishing-rolls, as shown at 22, 23, 24C, and 25, are provided for polishing the cord, removing or rubbing any slivers on the cord into the same, so that the slivers will either be removed or become united with the bodyof the cord by being embedded in the sizing material thereon and for giving the cord a high polish. The polishingrolls are rotated in directions reverse to the direction of passage of the cord past the same. Shafts 26, 27, 28, and 29 are provided for the rolls, respectively, journaled in bearings 81, 32, 33, and 34:. The rolls are rotated from anysuitable source of power, as by means of a belt taking about a pulley 35 on the shaft A twist-belt 36 passes from a pulley 37 on the shaft 26 to a pulley 38 011 the shaft 27. At the opposite end of shaft 27 a pulley 39 is located, having a belt 40 pass thereover to a pulley All on a shaft 28. The other end of shaft 28 also carries a pulley 42, from which motion is transmitted to a pulley 43 on shaft 29 by means of a twist-belt It. The polishing- rolls 22, 23, 2%, and 25 are preferably covered by so-called coir-rope spirally wound thereon, which coir rope is a hard rough-surfaced rope having abrading and polishing properties. The polishing-rolls may be given an adjustment transverse to the travel of the cord in order to contact with greater or less force against the cord, as by having bolts 45 take through slots 16 in the bearings. The adjustment of the drums for the track of the cord hereinbefore mentioned may be made by having similar bolts 47 take through slots $8 in the drum-bearings.

In my improved construction the cylinders and polishing-rolls are preferably inclosed in the drying-chamber or arranged in such manner that the polishing-rolls act on the cord after passing into the chamber and while being subjected to the drying-currents, thereby producing a high finish. It is obvious that these drying-currents may pass through the chamber in any desired manner to effect the desired result; but I prefer to cause them to circulate in a direction opposite to the general direction of passage of the cord, and I also prefer to divide the chamber into compartments, so that the drying operation may be more effectively, quickly, and economically performed. For this reason I have shown (see Fig. 5) the drying-chamber divided into two general compartments F F by a partition 51, having two inlet and two outlet openings for the drying medium. Each of the compartments is also provided with a partition 52, forming two passages for each compartment forthe guidance of the drying medium. In order to provide for the proper passage of the cord, however, I find it desirable to divide each of the partitions into two portions 51 and 52 and 51 and 52", the former taking about the outside of the line of travel of the cord and the latter taking within the inside of that line of travel and also avoiding the drums and rolls, with the strands of cord passing slightly diagonally between the outside and inside portion of the partitions. In this way I provide unobstructed passage for the cord, while causing the currents to follow predetermined paths.

The outside portion of the partitions may be secured to the casing or frame in any suitable manner, and the inside portion of the partitions may be hung on rods 54, projecting longitudinally of the casing from the ends of the casing or frame,the rods passing through apertures in the partitions, which latter may, if desired, be also secured from the rods against sidewise displacement or may be secured against similar displacement by the deflectors hereinafter mentioned.

In order to direct the currents of the drying medium in directions to produce the best results and to cause the circulation of the drying medium in directions that will produce the least obstruction from the parts in the interior of the casing and directing it in the most effective way against the cord to be dried and to provide for the circulation of the drying medium from the inlet past the strands of cord to the outlet-opening, I provide a series of deflectors, which I will now describe. These deflectors also serve the purpose of preventing.cross-currents in the interior of the casing. At the inlet-opening for the drying medium I provide two deflectors 61 62, converging toward the opening to direct the currents of the drying medium toward the side of the lower drum. On either side of the drum I provide a deflector (marked, respectively, 63 and 64) converging away from the inlet-opening to direct the currents of the drying medium against the strands taking about the drums. ielow the upper drum I provide other deflectors 65 66, converging toward the inlet-opening located between the strands taking about the drums to again direct the currents of the drying medium toward the strands and toward either side of the upper drum. It will be noticed that I also provide the upper end of the casing with deflectors in the shape of a dome (57, the current-s of the drying medium striking the in ner curved sides of the dome and being directed thereby to the second passage communicating with the outlet-opening. At the upper end of the latter passage and preferably just below the dome to either side of the drum I provide a deflector, (marked, respec- I tively, 71 72,) the deflectors being arranged to converge toward the outlet-opening of the drying medium and directing the current of the latter toward the strands of cord. Prefer ablyjust above the lower drum on the inside of the strands of cord I provide other deflectors 73 74, converging away from the outlet-open ing and directing the current of drying medium toward the strands and toward either side of the lower drum The lower part of the drying-chamber is also curved or provided with deflectors to direct the current of drying medium toward the outlet-opening. It will thus be seen that the current of drying medium is caused to pass and repass the cord while it is circulating through the chamber and in a direction opposite to that in which the cord passes through the dryingchamber. Thus the ingress-opening for the cord is at the same end of the chamber at which the outlet-opening for the drying medium is located, and the egress-opening for the cord is at the same end of the dryingchamber that the inlet-opening for the drying medium is located.

As will be noticed from Fig. 5, I divide the drying-chamber into two general compartments, with two inlet and two outlet openings for the drying mediums, the top of the casing being provided with two domes, one for each compartment. It is obvious, however, that the drying-chamber may consist of only one compartment, with one inlet and one outlet Opening for the drying medium; also, that the inlet and outlet openings for the drying medium may be located at other points than at the bottom, at which I have preferred to show them, and that any suitable number of partitions may be employed.

In the constructions heretofore in general use it has been the custom to pass the twine over interiorly steam heated cylinders.

These cylinders are expensive to make and have the added disadvantage that more or less of the steam is therein converted into water, which it is found difficult to remove and is a source of annoyance and expense. I obviate the objections to steam or otherwise heated cylinders in my improved device and provide a device economical in construction and operation and producing a superior product and one capable of imparting to the cord a superior finish and high polish and of economically and thoroughly drying the cord throughout.

The deflectors I have described may be secured in any suitable manner, as by being provided with flanges 75 and secured to the casing and partitions by means of bolts or rivets.

The drying-chamber may be provided with suitable openings, as shown at 7 7 for examination of the cord or other purposes, and the openings are adapted to be closed by suitable doors 78, which may slide in ways 7 9 and be provided with grips 80.

I do not limit myself to the particular construction herein shown and described, as alterations and changes may be made without departing from the spirit of my invention.
