PATENT OFFICE.

The bleaching machine enables the various treatments of fabrics for bleaching in one and the same vat.

In the accompanying drawing, α α represents the open vat made of wood or other suitable material. The same is provided with the perforated bottom bb , under which a pipe c with the two branch pipes ee and the drain tap d is attached in the middle of the bottom of the vat.

One branch pipe e leads to the container // with the bleach solution and at the same time to the container gg with the acid solution, while the other branch pipe leads to the closed container hh with the steam jet apparatus km . Each of these branch pipes has at the end of a faucet ii ^l.

The steam pipe kk, which is provided with the tap /, leads into the container hh at the bottom. This steam pipe ends below and inside the inverted funnel -m, which continues as a pipe outside the container hh and opens at η above the middle of the vat. Below this mouth of the Vertheiler depends ο in the form of a disc which the propagating through the pipe m supplied liquid over the entire surface to be bleached fabrics.

In addition, the water pipe ρ with the drainage tap q is located above the vat.

In the containers / and g for bleach solution and acid are the pumps rr ¹ , from which wooden channels s s lead to the vat aa .

A special tube e with cock i can be attached for each of the containers / and g , but a single tube is sufficient for the two containers if the opening t of the same is made of an elastic material, so that it can be connected to one or the other as desired can be connected to the other container.

This bleaching machine is used in the following ways:

All the taps are closed and the bleached goods are put into the vat. Now open the tap q and fill the vat with water to the required level. After q is closed again, the necessary amount of the abdominal remedy is added.

Then the steam tap /, as well as the tap ζ ' ^{1 are} opened, thus also the connection between the steam room, the container hh and the tub a a. '

The belly solution which now fills the container hh is carried away by the steam flowing out at k in the funnel m and is sprayed out through the pipe m and the mouth n, as well as distributors ο over the bleached material stored in the vat. As long as the cock i ^l remains open, there is also a constant influx _:. the belly solution over the substances to be bleached in the vat.

If the process of the abdomen has progressed far enough, the taps / and i ^{l are} closed again, while the drainage valve d is opened, whereby the abdominal solution drains out of the vat.

Now the faucet q is opened again and the bleached material is poured with water or washed, whereupon the taps q and d

closed and the cock i in the branch pipe e leading to the container ff is opened. The pump rr is then put into operation, which runs the bleach solution from the container ff in an uninterrupted flow over the material to be bleached and back into the container ff .

If this has been done long enough, the entire solution is drained from the vat through the tap i again into the container ff , whereupon the tap i is closed. Now the taps d and q are opened and the bleached material is poured with water or washed.

Now all the taps, with the exception of the one connecting the branch pipe e with the acid tank gg , are closed and the pump rr ^{1 is} put into operation. It sends an uninterrupted supply of acid solution to the material to be bleached. After this long enough place, the pump is out besides gear and the contents of the vat into the acid container gg back run.

Then the tap i is closed and the bleached material is again poured or washed with water through the tap q; Reasoning by the cock q läfst drained the water contained in the bleach goods.

Now close the drain tap d and fill the vat again through the tap q with a sufficient amount of water, to which the appropriate amount of soap is added after the tap has closed.

Now we leave again by opening the taps / and i ^1, the soap solution running hh into the vessel, from where it is distributed through the steam jet on the same kind in the tub and on the bleach goods as before the Bäuchlösung. If the soap solution has acted long enough on the substances to be bleached, close / and i ¹ pnd open d to let the soap solution out of the vat. With the help of the faucet q you can water or wash the bleached material again or, if you like, wash it out by hand.

If another bleaching is necessary, the same treatment can be repeated, and as often as one wants, without it being necessary to bleach out the substances to be bleached to take from the vat.

By using a separate container hh for the steam jet apparatus km , one has the advantage of being able to use a tub that is completely free on the inside and without pipes. However, it is not these containers hh absolutely necessary, into which you can place the steam jet apparatus in the tub itself.

The liquid as well as the soap solution are thrown up in this case from the perforated bottom bb of the vat into the mouth of an inverted funnel by the steam jet flowing out of the same, exactly as described for the container h H. This is the usual method of common iron vats; the steam pipe entering the vat and the funnel must either be made of lead or be protected against the effects of the bleach solution and acids by a wooden paneling.

Claims (1)

Patent claim: The construction of the bleaching tub α and the connection of the same with the steam jet apparatus mk, as well as the containers / and g for the bleaching agent and acid, which makes it possible to carry out the various works of bellying, bleaching, acidifying, washing, soaping and washing out without this To remove bleach from the vat or to disturb or change the position of the same in this vat in any way. For this purpose ι sheet of drawings.
