Specification of Letters Patent. Patented May 27, 1919.
Application filed June 17, 1918. Serial No. 240,554.
To'all whom it may concern Be it known that we, SILAs J. MoCAUGH- BIN and EILERSLIE W. BULLARD, citizens of the United States of America, respectively residing at Birmingham, Jefferson county, Ala, and Anniston, in the county of Calhoun and State of Alabama, have invented certain new and useful Improvements in Calendering-Machines for Spinning-Rolls, of which the following is a specification.
Our invention relates to mechanism for producing a smooth and even surface on spinning rolls which are covered with leather cots or the like.
Our object is to produce a smooth, even polished surface for the roll which will enable it to produce yarn of even size and strength and of uniformsmoothness, and which will prevent it from licking up.
The general practice in this art is to smooth the cloth covering of the iron roll by rolling the same between evening rolls,
' after which the leather cot is pulled on.
The rolls as thus produced are subject to defects which result from the surface thereof lacking in the smooth contour and polished surface which is necessary for the bestresults. These imperfections in the rolls result from various causes such as rough handling in covering the rolls; unevenness resulting from the stretching of the leather. cot in pulling it on the roll; the presence of foreign substances beneath the cot such as lumps of glue, small particles of lint, etc.; irregular lap joints, an underlap or overlap of the scarfed ends of the cot which will give it a tendency in stretching to draw the lapped ends apart and produce a corruga tion; the cup-like indentations formed by the stretching of porous flank leather, and unevenness from burning down the ends of the cot. These imperfections generally ocour in the present method of manufacture after the roll has been passed through the evening rolls, and as a result the imperfections exist when the roll is placed in the spinning frames as they are generally too slight to be detected by touch.
The object of our machine is to calender the finished spinning roll by pressing the same between rolls, part of which are heated, in such manner as to produce the desired smoothness and polish to the leather surface of the roll.
A further object of our invention is to simplify the construction of the calendering machine especially with reference to the manner of heating the rolls to the end that the machine may be produced economically and operated without appreciable maintenance charges.
Our invention further comprises the novel details of construction and arrangements of parts, which in their preferred embodiment only are illustrated in the accompanying drawings which form a part'of this. specification, and in which Figure 1 is a plan view of our calendering machinevwith the rolls partly broken away to illustrate their internal construction.
Fig. 2 is a sectional View taken on the line A-A of Fig. 1; and
Fig. 3 is an elevation of one end of the machine. V Y 1 7 Similar referencenumerals refer to. simi lar parts throughout the drawings.
In the embodiment of our invention illustrated in the drawings, we show three rollers 1, 2 and 3 running in separate bearings and mounted in triangular relationship, the upper r0113 being solid and the'lower rolls 1 and 2 being cylindrical in form and all having their outsides turned to true cylindrical surfaces. The rolls 1 and 2 have their ends reduced and mounted in bearings 4 in end bearing frames 5 which are bolted to a bed or base 6 and are cross connected by a pair of bottom bolts.7 to hold them in rigid relationship. Twin pulleys 8 are mounted on the corresponding ends of the hollow rollers 1 and 2 and a belt 9 is passed over both of these pulleys so as to cause them to travel in the same direction. The top roller 3 has its ends reduced to form trunnions 10 which turn in bearings at the free ends of rocker arms 11, which arms are keyed to a rocker shaft 12 mounted in rear bearing extensions 13 of the bearing frames 5. As shown the bearings for the rolls 1, 2, and for the rocker shaft 12, all have a common cap plate 14: which is screwed to the bearing frame. In the center of the rocker shaft I provide a crank arm 15 to which any suitable operating connection may be provided, such as a handle, treadle or the like, whereby the up per roll 3 may be raised or forced downwardly toward the hollow rolls '1 and 2. In Fig. 2 we show a spinning roll in position in the calendering machine having its central metal core 17 with a cloth covering 18 and a leather cot l9 stretched over the cloth.
In order that the hollow rolls 1 and 2 may be heated so as to produce the proper surface on the spinning roll, we employ a steam heating arrangement comprising a supply pipe 20 having a valve 21 therein under control of which steam or a like heating agency is admitted to a heating pipe 22 which passes longitudinally and centrally through the roll 2 and beyond its pulley, this pipe being mounted in a ring bearing 23, beyond which its threaded end projects and has screwed thereon an elbow 24: which is connected by a nipple 25 with a similar elbow 24 screwed on the end of a heating pipe 26 which passes centrally and longitudinally through the hollow roller 1 and is supported in'the ring bearing 27, similar to 23. These bearings 23 and 27' are mounted by pipe supports 28 on socket bases 29. The heating pipe 26 connects to any suitable return pipe or exhaust. By this arrangement the heating coils are independent of the surrounding hollow rollers l and 2 so that no packed joints are required and yet an even heat will be maintained by radiation from the pipes 22 and 26 to the calendering surface of their respective rolls 1 and 2.
In operation, after the cloth covering has been smoothed by the evening rolls and the cot 19 drawn thereon the spinning roll is inserted between the rolls 1, 2 and 3, the top roller being raised to permit its introduction. The weight of the said top roll 3 serves to force the spinning roll against the rotating calendering rolls 1 and 2 and is sufficient to produce by the pressure and heat of the calendering rolls a smooth and polished surface on the leather covered spinning roll. The arrangement of the rolls shown is the simplest and least expensive for accomplishing the ends in view but the same may be varied so long as the principle of action is maintained.
This invention is not intended to be restricted in scope to the specific embodiments shown, but contemplates such modifications as c0me..w1th1n the splrit and scope of the claims;
1. An apparatus for smoothing and polishing the surfaces of spinning rolls, which comprises, in combination, heated calendering rolls, means to drive the rolls in the same direction, and a presser roll adapted to press a spinning roll against the calendering rolls substantially as described.
2. An apparatus for smoothing and polish ing the surfaces of spinning rolls, which comprises, in combination, hollow calendering rolls, heating pipes extending through said rolls, means to drive said rolls in the same direction, and a presser roll adapted to press a spinning roll against the calendering rolls.
3. An apparatus for smoothing and polishing the surfaces of spinning rolls, which comprises, in combination, three rolls, bearings supporting said rolls in triangular relationship, two of the rollers being hollow, a Ushaped steam pipe having itssidespassing freely through said hollow rolls, and means to move the unheated roll relatively to the heated rolls, substantially as described.
4. An apparatus for smoothing and polishing the surfaces of spinning rolls, which comprises, in combination, a pair of hollow rolls, bearings therefor, a steam. pipe passing freely through one of the rolls and returning by a reverse bend through the other roll, supports for the pipe, a swinging frame, a solid presser journaled in the frame and movable therewith by gravity into position to press a spinning roll against the hollow rolls, driving pulleys on the adjacent ends of the hollow rolls, and belt means to drive said pulleys in the same direction.
In testimony whereof We afiix our signatures.
