DRIER AND STEAMER FOR 13113111.1112.'rninrczstl Application filed November 21, 1927'. Serial No. $234371.

Tubular knitted or woven fabrics, if made ot silk, libre, cotton or wool7 or mixtures of` these, are in most cases dyed, bleached or washed. `After the operations referred to the abric is put 1n an extractor to extract the liquid. Although the liquid is extracted to a considerable extent the fabric still remains moist and requires drying. Alter the fabric is dried it is necessary to subject it toa steaming process to make it sott and to give the fabric the right linish.

My invention relates more particularly to drying means and to the relation ot the` drying means to a steaming device, the purpose in view being to effect the drying and steam ing of the fabric in one operation and the eftesting of a saving in time and labor.

The nature of my invention and its distinguishing features `and advantages will clearly appear as the description proceeds.

Reference is to be had to the accompanying drawings forming part otthis specitication, it being understood that the drawings are merely illustrative of one example of the invention. y i

I have shown in the illustrated example of y my invention the adaptation of the drying means constitutinof the present invention to a steaming assemblage forming part of the subject matter of an application for patent tiled by me November 4, 1927 Serial No.

231,124.' In the steaming assemblage referred to a steam bowl 10 is provided openY at` the top for theescape of the steam. Said bowl is closed by asolid disc 11 having a central bore and a nipple 12`on saiddisc which nipple extends into a steam pipe 13 mounted on a suitable base 14 and supplied with steam through au inlet pipe 113.` The `pipe `lrisesftrom the d1sc"11 or bottom of the bowl 10 at the nipple .131 so that the" steam "flowing from said nipple 12 will pass into` the pipe 15` which isformed with aseriesof apertures he upperl endof the pipe 15 is reduced las at 17 and ex-` ternally threaded to receivefthe bottom 18 of` a steam dome or drum`19 which is screwedto 1G tor the escape of thesteam.` 1

said reduced terminal "17.` f Steam dome 19 is filled with steam passing into the samefroin pipe 15.

The bottom 18 oft the steam dome ondrum` 19 is spaced from the open vupper end of` the steam bowl 10 by an` outlet space 2() `thercbetween for the ample flow ot steam outwardly to contact with the tubular 'fabric A, indicated in dot-and-dash lines, `as said 'labricis drawn upwardly overtlie bowl 10,

dome 19and overa stretcher'21.

The stretching frame 21 isfan `open trame thefsides ofvvhich risefrom the bottom bar 22 y A threaded #bolt 24 passes u through bottom barV 22 `atthe `center and of said frame.

through a disc `25.011 the plug 119orming a closure at thetenter` at the top ofthe dome 19.`

Screw bolts 27 1pass through disc 25 and into,"

the plug or block 119 as fully disclosedin my Vabovementioned application. Y i

1A stretching ring 30 is providedon'tlle` dome 19 `and removably held seatedfupon washer 4L Forthe removable holdingof` collar 3() the same is formedwith notches 31 at its inneiI periphery` and onthe dome 19 are f i outwardlyprojecting pins 32`fsot-hat the col-` lar may be passed downwardly beneath the y horizontal planeet pins 32 and tbe collar then f given a partial turn for the pins to hold said collar in place. The collar 41 rests upon the upwardlydirected annular llange 39 en dome 19 and the bottom `18`is`clamped by screws 42:

between said `flange 39and ring `l0 on the under side o1. said "bottom `18. Drip pipe 35 leadsrfrom the bottom ofdome `19 into `steam bowl 10`t `direct to said bowl the Water of i condensationfrom the dome `19. Similarly `a drain pipe 36 leads fromlsteam bowl 10 to carry off the water of condensation. The numeral 37 indicates {iange or collar on the steam pipe 13 which is suitably secured to the solid bottom 11 of dome 10.

The assemblage above described provides for the free flow of steam to the fabric and in order that the space 20 forl the outflow of the steam may be Varied, I provide collars r washers34 on the reduced end 17 of pipe 15, said collars being employed in suitable number according to the size to be given to space 20. Y

With steam-dome 19 filled with steam the `said dome serves to dry tlie fabric passing over thesame when drying isrequired. The steam escaping through the space does not actually wetthe fabric, and in some instances when the fabric is moist. from too much steam the dome 19 has the desired drying effect. lVheii vdrying is not desired the dome 19 is closed against the entrance of steam by einvploying a plug in the reduced end 17. A plug 135 is also employed to close the lower end of drip pipe 35 when the steam dome 19 is closed against the entrance of steam in order to prevent steam passing into said `dome through pipe 35 from the bowl 10. Y

In accordance with iny present invention the drying means includes a cylindrical shell which surrounds the steam supply pipe 13 as well as the drain pipe 36. An air inlet pipe 51 leads laterally into shell 50 and is sup plied with air under pressure. Said shell 50 is closed by any suitable means at the top and bottom, there being shown a plug formed of half sections 52, see more particularly Figure G. The shell 50 terminates at the top short of the bottom of the steam bowl 10, the pipes 13 and 36 extending beyond the upper closure elements 52 to a connection with, said bowl `10. y Surroundingthe shell 50 at any desired point in its height is a perforated drying drum 53, in which shell 50 there are perforations 54 for theescape of heated air to the drum 53. The airescaping from the perforated druni into contact with "and passing through the fabric effects the drying ofthe fabric. The drying drum 53 may rest on a fired collar 55 on the air tube or shell 50. At

the top of said drum 53 is a set screw A56 to bind the drum on the shell 50 at any desired height. thereon that will permit air to pass' into drum 53 from perforations 54. By loosening the screw 56 the drum 53 may be slipped upwardly and entirely removed from the shell 5() after steam bowl 10 and steam drum 19 have been removed from the upper end of the pipes 13, 36.

Vlfith the steam. bowl 10, steam `drum 19 and drying drum 53 removed from the assemblage, the fabric may beslipped downwardly a drying shell having an inlet for drying over the shell 50. In order to facilitate the placingof the tubular fabric over` the pipes 13, 36 and shell 50, I provide,` as in Figures 7 and 8, a dome 57 depending from which is a plug 58 adapted to fit in the upper end of the steam pipe 13, as shown clearly ni Figure 3.

In the use of the above described device the fabric having been placed in posi tion, as in dicated in dot-and-dasli lines in Figures 2 and 3, any remaining moisture in the fabric will be driven off and the fabric made dry bytlie drying air escaping from the perforations 5a of shell 5t) and through the perforations in drum The drying will thus be effected as the fabric drawn upward over the drum 53. As the fabric passes from the upper end ofthe shell 50 it is drawn over the bowl l() and drying druni 19 and is steamed to give it the proper finish. The drying of the fabric and the steainiiigthereof to produce the desired finish is effected in succession as the fabric is drawn continuously over the drum 53,'shell 10 and steam drum 19. The drying action is materially promoted by the described assemblage since the steam pipe 13 and to a lesser degree the drain pipe 36 serve to heat the air passing to shell 50 and drum 53.

The numeral 60 indicates a. platform or table on which `fabric A rests.

I would state furthermore that while the illustrated example constitutes a practical embodiment of my invention, I do not limit myself strictly to the exact details herein il lustiated, since, manifestly, the samecan be considerably 'varied without departure from y the spirit of the invention as defined in the surrounding the shell below the upper `end thereof and adapted to permit an outfiow of air to a fabric -diawn over the drum, and steaming means communicatnig with said pipe and located `for the fabric to be drawn over the saine after drum.

3. In an assemblage of the class described, a drying shell having an inlet for drying air and means on the drying shell over which the fabric may be drawn, and a drying drum surrounding the shell, said means permitting the outflow of air to the fabric passing over the drum. i V

4. In an assemblage of the class described,

passing over the drying air, a collar on said shell, a drum resting on said collar, and means detachably holding said drum against displacement on said shell affording an outfiow of air for the drying of lili) the tubular fabric being drawn over the drum.

5. In an assemblage of the class described, steriining means, a steam pipe, a perforated shell surrounding said steam pipe and llaving un .inlet for drying air, and a perforated drying drinn on seid shell adapted to receive drying'l nir therefrom, said drum being vertically adjustable, and means for holding the drum in dierent positions on the shell.

Signed at New York, in the county of New 10 York, and Stute of New York, this 18th day of November A. D. 1927.
