CONTINUOUS MACHINE FOR TREATING FABRICS.

Application :tiled September 16, 1927. Serial No. 220,033.

This invention relates to a washing or scouring machine for cloth in the cut and is also applicable to bleaching and dyemg machines for treating fabrics continuously 1n 5 long lengths. i

The principal object of the inventlon 1s to provide an arrangement in the case of washing or scouring machines by whlch the cloth, as it comes from a crabbing machine l with several cuts of cloth in a single length,

can be taken therefrom and threaded into the scouring machine, without ripping apart saving in the process of dyeing and bleaching. The invention also involves the provision of means located back of the rolls for guiding the clothalong the machine from one' end to the other in order to provide for the continuous operation and other features of construction and combinations of parts.

Other objects and advantages of the invention will appear hereinafter.

Reference is to be had to the accompanyindrawings in which e ig. 1 is a front view of a scouring machine with a preferred embodiment of this invention applied thereto;

Fig. 2 is a sectional view of the same on' the line 2-2 of Fig. 1;

o Fig. 3 is .an end view of the ladder and associated parts extending along the back of the machine; and' Fig. 4 is a view like Fig. 2 on a small scale showing the invention as applied to a reel machine for dyeing or bleac ing.

Ordinarily, cloth comes from the loom in cuts which are about fifty yards long and ordinarily is taken through a fulling or crabbing machine. The cloth goes through the fulllng machine in fifty yard lengths and together. In the ordinary machine' it is' stopped eight times. After Washing, the cloth goes to the vacuum extractor, before it enters which, it is sewedtogether to form a single length of eight of these cuts.

When a crabbing machine is used, the eight cuts of cloth are sewed together .in one long length While it is going through the machine. When it comes out, these seams are ripped apart to put it through the ordinary scouring machine and then they are sewed together again to go through the extractor and folding machine in one length.

This machine is designedto save all but two -of the ripping and sewing operations and, not merely to save these operations but, to save the delay occasioned by their taking place while the machine is stopped oncev for each seam. In this machine, the `cloth coming in one long length from the crabbing machine does not have to beripped into eight lengths and then sewed eight times, but is simply ripped once and then strung intothis present machine and sewed once 80 to make an endless strand. On coming out, it is simply ripped once kand put into the extractor, through which` it goes in one long length to the folding machine.

I have shown the invention as applied `to well known types of scouring and dyeing machines. Referring to Figs. 1 and 2, the cloth comesthrough a series of eyes 10.

" Instead of each length passing through a separate eye, the whole length of'eght pieces 90 is strung through the several eyes 10 one after the other in the manner indicated.

process is repeated over `and over..`

Asesl At the end the fabric goes up from the bottom past the last eye over a guide-roll 16 mounted on the shaft with the roll 11 under a roll 17 which is hung on a lever 18 and weighted Iwith a weight 19 so as to squeeze some of the liquor out, then up over a guide-roll 20 which is mounted on another ladder or convenient support 21. The cloth -vis drawn through here to another guide-roll 22 through a wicket or loop 23 to guide the cloth so that it will necessarily pass-over -this roll 22 and not run 0H the ends thereof and then goes down under a guide-roll 24 and. either out of the machine or back to the base through the liquor several more times. The three guide-rolls 20,

`'22 and'24 are ofthe same size preferably.

The upper ladder merely supports the cloth in case there is any slack between the rolls 20 and 23. It will be noticed that the fabric comes up to the eyes at an inclination instead of vertically as heretofore and that has an advantage inthat the cloth is prevented from being rumpled up just before 1t enters the eye but, on account of the inclination, is allowed to spread by gravity. The roll 16 is made larger than the roll 11 to take up the slack and feed it forwardl more rapidly.

lhe showing of the invention in Fig. 4 as. applied' to a bleaching or dyeing machme is to illustrate another way in which the invention can be carried out, in which a reel 30 is employed over which the clothv gloss time after time in a progressive manner omI one end to the other as it goes through the machine. Here the liquor drains out between the' operations. The
