CLOTH-SHRINKING MACHINE.

SPECIFICATION forming part of Letters Patent No. 459,021, dated September 8, 1891.

Application led .Tune 17, 1891. Serial No. 396,589. (No model.)

T0 @ZZ whom t may concern;

Be it known thatLCHARLEs W. SCHAEFER, of Cleveland, in the county of Cuyahoga and State of Ohio, have invented certain new and useful Improvements in Clotli-Slirinking Machines; and I do hereby declare the following to be a full, clear, and exact description of the invention, such will enable others skilled in the art to which .it pertains to make and use the same.

My invention relates to improvements in apparatus for steaming cloth; and it consists in certain features of construction and in combination of parts, hereinafter described, and pointed out in the claims.

The accompanying drawing presents an elevation in central section of a device embodying` my invention.

A represents an upright hollow cylinder closed at the ends by means of heads a a. The cylinder between the heads has numerous small perforations to allow the steam to escape from the cylinder into the cloth that is supposed to be wound around the cylinder. The lower head d has a drip hole a2 for the escape of condensed steam, and the cylinder has a depending rim A at the bottom, that the cylinder stands on. This rim sets in a vessel. B, and as soon as a little condensed steam passes beneath the rim AA and accumulates in the vessel a water seal is formed around the lower edge of the rim of the cylinder, that prevents the escape of steam at this point.

C is a steam-pipe that enters the cylinder from above through a central hole in head cz, a stufiing-box being provided, as at C2. This pipe C is supposed normally to extend to near the Abottom of the cylinder, from whence the steam on entering the cylinder rises and fills the cylinder, and from thence passes out through the perforations of the cylinder into the cloth. The cylinder is supposed t0 be long enough to accommodate the widest cloth to be steamed-that is to say, the narrow or single goods are wound singly on the cylinder,while the wide or double-width goods are wound double on the cylinder, so that usually there will be but a few inches in width variation in the different kinds of goods as applied to the cylinder. In case the cloth is narrow, if wound next to the bottom of the cylin'derthe perforations would not be covered by the cloth near the upper end of the cylinder, in which case the steam would mostly es cape thro ugh these unobstructed perforations, so that but little steam would enter the cloth. To prevent this I provide a disk D, mounted on and rigidly secured to pipe C inside the cylinder, The periphery of the disk is provided with a groove and packing,v as at d, so as to make a steam-tight joint with the inside of the cylinder. The packing' of the disk and of the. stuffing-box causes sufficient friction to hold the pipe and disk in place without other fastening, but these members can be moved up and down the cylinder by hand. It' the cloth is wide enough to cover the entire perforated section of the cylinder, the disk by means of the pipe is d rawn up against the upper cylinder-head. On the other hand, if the cloth is narrow it is wound on the cylinder, so as to cover the perforations at the bottom of the cylinder, and then the disk is depressed by means of the pipe,so as to conne the steam to that portion of the cylinder that is covered by the cloth.

Gr is a steam-generator, that may set, for instance, on a stove or over a gas jet or burner, and 'from this generator leads a small steampipe C', connecting with the upright pipe C aforesaid. Only a slight pressure of steam is required, and dry or superheated steam is not desirable for the purpose, but, on the contrary, the wetter the steam is on entering the cylinder the better, and pipe C is preferably of considerable length, in which case this pipe will readily bend to accommodate the limited movement up and down of pipe C. If for want of room pipe C was necessarily short, an elastic tube could be subtituted for a metal pipe, or a joint could be had in the metal pipe. Then the steam is discharged into the top of the cylinder, the most ofthe steamwill escape at or near the top end of the cylinder, and hence the lower portion of the cloth will receive little or no steam, especially as the supply of steam is likely to be quite limited. lith the construction shown, while the steam discharges near the bottom of the cylinder, the tendency of the steam being to rise, the cylinder becomes filled with steam, and the discharge through the perforations is more nearly equal throughout the length of the cylinder, by rea- IOO son of which the cloth is treated substantially the same throughout its width.

The union between pipes C and Cy comprises, preferably, a female sanember c', having a conical bore adapted to iit the corresponding conical male member c, the latter being secured to pipe C, whereby pipe C may be raised by hand to separate the pipes, so that the cylinder can be disconnected foi-con- Venience of winding the cloth thereon, it being found more convenient to roll the cloth on the cylinder by rolling the latter on the table. The friction, as between members c c', is sufficient to hold the parts in contact as against the slight pressure of steam employed, and of course the gravity of pipe C also aids in holding the parts together.

That I claim is- 1. In cloth-steaming apparatus, an upright hollow perforated cylinder closed top and bottom and provided with an induction steampipe discharging downward into the cylinder near the bottom of the latter, substantially as set forth.

2. In clothsteaming apparatus, an upright hollow perforated cylinder having an induction steam-pipe discharging downward into the cylinder near the bottom thereof, a disk mounted on the steam-pipe inside the cylinder, the disk and pipe being adjustable length' 3o wise of the cylinder, substantially as set forth.

3. In cloth-steaming apparatus, an upright hollow perforated cylinder and a steam-pipe, arranged substantially as indicated, the cylinder having a depending rim with a drip-hole 35 discharging inside the rim, the rim serving as a supporting-base for the cylinder, the rim being seated in a vessel, vwhereby the condensed steam forms a water seal around the bottom of the rim, substantially as set forth. 4o

4. In cloth-steaming apparatus, an upright hollow perforated cylinder and a steam-pipe, the latter entering the cylinder through a hole in the top head thereof, this pipe connecting with a steam-pipe leading from the 45 generator by means of a conical union held in place by friction or gravity, or both, substantially as set forth.

p In testimony whereof I sign this specification,in the presence of two witnesses, this 1st 5o day of May, 189i.
