APPARATUS FOR DRYING AND CONDITIONING YARNS, 80C.

SPECFICATION forming part of Letters Patent NO. 710,467', dated October 7, 1902. Application filed January 14,1902. Serial No. 89;'767. (N0 model.)

To @ZZ whom t pray concern:

Beit known that we, JAMES KEITH, residing at 27 Farringdon avenue, and WILLIAM XVIN- SHTP TWARDLE, residing at 32 Someriield road, Finsbury Park, London, England, citizens of Ithe United Kingdom of Great Britain and Ireland, have invented certain new and useful Drying-Chambers and Apparatus for Drying and Conditioning Yarns, Fabrics, and other Goods, (for which application for patent has been madein Great Britain, No. 12,389, dated .lune 1S, 1901,) of which the followingr is a specification.

This invention relates to drying-chambers and apparatus for heating and circulating air therethrough for the purpose of drying and conditioning yarns, fabrics, and other goods; and it comprises improvements in the construction and arrangement of such chambers and apparatus for conveying the goods through the drying-chambers while being acted on by the circulating airand automatically delivering them, whereby the necessity for operators entering the heated chambers is obviated.

In the accompanying drawings, which illustrate the invention, Figure lis a vertical longitudinal section of a drying andconditioning chamber and accessories constructed and arranged in accordance with the invention; and Fig. 2 is a longitudinal section of the same, the section being taken on two different planes. Figs. 3 and 4 are detail views at right angles to each other of part of the conveying-band.

The apparatus hereinafter described is capable of drying and conditioning yarns and the like in hank form; but the means for conveying the goods through the drying-chambers is particularly designed for holding woven or other fabrics or garments and for sheets of paper or like flat goods to be dried.

The drying-chamber a has vertical sides and a sloping roof Z), near which a circulating-fan c is situated in a vertical Wallf, extending downward for a short distance and dividing the upper portionrot' the chamber a into two compartments. Heating apparatus, such as a coil of steam orhot-water pipes CZ, is located in proximity to the Vlan c immediately under the sloping roof l), and another series ot steampipes e near the bottom of the chamber in proximity to the fresh-air inlets g. Air is drawn, as shown by the arrows, from one side of the vertical wallf by the fan c and discharged ou rthe other side, the air passing through the heating apparatus d to and through between the goods being dried or conditioned, the air so directed, together with fresh air drawn in, being directed toward the lower heating apparatus e and thence upward again to the suction side of the fan c. The surplus or moist air is discharged by a ventilator 7L on the sloping roof, an exit-passage t' being provided in the wall of the building for carrying this surplus air to the atmosphere.

The apparatus for conveying the goods to be dried through the drying-chamber o. consist-s, as shown by the drawings, of endless bands j, passing around rollers 0, said bands being made up, as shown particularly at Figs. 8 and 4, of chain-links Zr., preferably of T shape, the chain-links 7c being formed with or having attached to them cross laths or blocks Z, to which holdingclips 'm are jointed, the under side of the bandj being steadied and guided in side rails n. The holding-clips m consist of rollers jointed to the blocks, as shown, the arms p of the joint being of such length that when the clips m are in an approximately horizontal position they rest against the forward side of the adjoining block Z. The goods are inserted between the clip m and the vadjoining block Z by pushing the goods against the rollers m, and thereby raising them, the clips on again reaching their normal position engaging and firmly holding the goods, which in the case of sheets of paper or of garments extend transversely of the chamber d, as shown at oc, Fig. 2, from a clip on one bandj to a clip on the adjacent baud j.

For convenience of inserting and deliveringV the goods' the rollers o, around which the chain-links 7o pass, are fitted in proximity to or without the end walls of the chamber CZ, so that the goods may be placed into clips m by the operator, and at the opposite end the goods are automatically delivered as the chain-links 7s ride around the roller o, owing to each lath or block Z in the turning opera tion moving away from the clip m, jointed to the lath or block Z behind, as shown at Fig. l.

IOO

The blocks Z are formed with heels q to prevent the clips m dropping below the horizontal position when the blocks Z are passing around the rollers o.

The goods are dried by the action of the heated air in their passage through the drying-chamber a, and the operator is not under the necessity of entering the chamber, but merely slips up the goods through a doorway r into the clips fm at the feeding-in end and may at the same time actuate a hand-wheel n on the spindle of the roller 0 to move forward the endless bandj, carrying the clips m, the automatically-delivered goods being periodically removed by a door at the opposite end.

Having now described the invention, what we claim, and desire to secure by Letters Patent, is-

l. Means fordrying and conditioningyarns fabrics and other goods comprising in combination a dryingchamber having vertical walls and a sloping roof a ventilator in said roof a vertical wall extending downward from the sloping roof vand acirculating-fan located in said vertical wall, heating apparatus situated in proximity to the fresh-air inlets and close to the discharge side of the fan, an endless-band conveyer passed around rollers for carrying the goods to be dried through the heating-chamber said conveyer being composed of blocks or laths fixed on the links of endless chains, and clips on these blocks adapted to engage and hold the goods and to automatically release them at the discharge end substantially as described.

2. In chambersfor dryingand conditioning yarns fabrics and other goods, a conveyer for carrying the goods through the chamber composed of an endless band of chain-links passing around roller-blocks secured to said links and rollers jointed to said blocks adapted to engage with and hold the goods while traveling through the chamber and to free the goods at the discharge end of said chamber substantially as described.

In witness whereof we have hereunto set our hands in presence of two witnesses.

JAMES KEITH. WILLIAM WINSHIP W'ARDLE.
