Dec. 4, 1951 J. DUNGLER DYE PADDER HAVING VERTICALLY OR HORIZONTALLY DISPOSED SQUEEZE ROLLS 2 SHEETS--SHEET 2 Filed Oct. '7, 1947 Patented Dec. 4, 1951 UNITED STATES PATENT OFFICE DYE PAYDDER, HAVING VERTICALLY R HORIZONTALLY DISPOSED SQUEEZE ROLLS Julien Dungler, Basel, Switzerland Application October 7, 1947, Serial No. 778,371 In France October 9, 1946 either in the form of a vertical padder, or in that` of a horizontal padder, and `which can thus be adapted to the most varied uses, in particular as a padder for wringing, or as a padder for impregnating (dyeing, dressing, etc).

This universal padder is essentially characterised in that it comprises one or a plurality of rollers mounted in a support which can be made to swing about the axis of a stationary roller in such a manner as to obtain at will a vertical arrangement or a horizontal arrangement of the padder.

An embodiment of such a padder is described hereinafter and diagrammatically illustrated, merely by way of a non-limitative example. in the accompanying drawings in which:

Figs. 1 and 2 are vrespectively views in front and side elevation of a universal padder with two rollers, in its position for use as a vertical padder.

, Figs. 3 and 4 being corresponding views showing it in its position for use as a horizontal padder.

On a stationary framework I is mounted `a roller 2 forming a lower roller in the vertical roller arrangement (Figs. 1 and 2) and the shaft 3 of which is given a rotary movement by means of

gears

4, 5, the latter gear being mounted on a shaft 6 driven by an electric motor 'I by means of a pulley drive 8, 9 and belt Ill. A portion of said roller 2 is located inside an open tank I I supported'by angle irons 23 of the framework I.

A roller I2, forming the upper roller in the vertical roller arrangement, has a shaft I4, which is mounted by means of each of the bushings I3 in a support I5 in which the bushing can slide by the action ci a hydraulic device I6 away from roller 2 and in opposite direction by the action of a spring VI when the pressure exerted by the aforesaid device is eliminated. According to the invention, the assembly formed by the two supports I5 braced by the upper cross member I8 is so mounted that it can be madek to effect a pivoting movement about the axis of the roller 2. For this purpose, the lower part of each of the supports I5 is provided with a head I9 which is adapted to rotate with corresponding end of the I shaft 3, said head I9 being provided with a It will therefore be readily understood that bylf'l actuating the handwheel 20, it is possible to move M or'swing the whole arrangement supporting the roller I2 from the position shown in Figs. 1 and 2 downwards into the position of Figs. 3 and 4, thereby converting the vertical padder into a horizontal padder.

Rollers

24 and 25 mounted on the supports I5 act as guides for the cloth to be treated, and rollers 2t and 2l provided inside the tank I I also serve for this purpose.

The universal padder operating as a vertical padder (Figs. 1 and 21), can be used, for example, as a squeezing padder by passing the cloth directly into the horizontal plane forming thetangential plane common to the two rollers 2 and' I2, and the tank II serving to collect the liquid expelled, or as a padder for impregnating processes (dyeing, dressing, etc.) by causing the cloth to follow the path shown in the drawing, the tank II in that case containing the treating liquid.

The universal padder operating as a horizontal padder (Figs. 3 and 4) can be used, for example, as al squeezing padder, or again also as an impregnating padder, the tank I I in this case containing the treating liquid and the cloth passing rst of all through the tank I I, then between the rollers 2 and I2 which are accommodated with open tank I I, as seen in Fig. 4.

Other possibilities are offered by arranging the pair of rollers 2 and I2 so as to form a troughreservoir, in particular in the manner described by the applicant in his U. S. Patent No. 2,511,625, dated June 13, 1950.

For this purpose, the roller 2 is provided, on either side, with a sealing plate 29 which is resiliently pressed against the corresponding end surfaces of the rollers 2 and I2, and which is of sufficient size for it to form a flat end surface for the trough formed between the horizontally arranged rollers 2 and I2. This trough can thus be used as a reservoir for a uid, semi-uid or pasty product 39`intended for dyeing, dressing, or other treatment. For dressing, for example, it is Dossible to apply the product both sides of the cloth by causing said cloth to travel in the manner shown at 28', or again only to one side by causing it to travel in the manner shown at 28".

It is of course understood that it is possible, without exceeding the scope of the invention, to devise modications, improvements of detail and uses of equivalent means.

Having thus described the invention, what is claimed as new and desired to be secured by Letters Patent, is:

1. A universal padder comprising a pair of engaging pressure rollers, driving means operatively connected to one of said pressure rollers whereby rotation may be imparted to said pair of pressure rollers, an open tank into which said one pressure roller extends in one position oi said pair of pressure rollers, said open tank being of such dimension as to accommodate therein said pair of pressure rollers when the latter are shifted to another position, a shaft for said one pressure roller, sealing means on said shaft and abutting against said one pressure roller, said sealing means extending` beyondsaid one pressure roller for contact with said other pres sure roller, and means positioned adjacent said one pressure roller and adapted to move the lat` ter about the axis of said shaft for shifting said other pressure roller` from said one position to said other position in Which said pressure rollers are disposed in side-by-side relation in saidrtank.

2. A universal padder comprising a pair of engaging pressure rollers, driving meansl operatively connectedL to one or"A said pressure rollers.

whereby rotation may beiinparted to, said pairy of pressure rollers, a shaft for said one pressure roller, sealing means on said shaft andabutting againstv said one roller, said sealing means extending beyond said one pressure rolier for contact With said other pressure roller, and means positioned adjacent said one pressure roller and adaptedf to move the latter' about the axis of saidY shaft for shifting said other pressure roller from one position in which said rollers are engaged in superposed relation to each other. to another position inwhich said pressure. rollers are disposed in side-by-side relation to. each.

other,`

3,. A universal pad'der` comprising a pair of' engaging pressure rollerseach havingiend faces,

driving means operatively, connected to one of' said pressure rollers'wherebyrotation may be imparted to, said pair of pressure rollers, a shaft forn said one pressure roller, a frame support for said otherpressure roller-and journalled on said shaft to swing thereaboutfrom one position of said pair of pressure rollers to another position of said pair of pressure rollers, sealing means on 4 i said shaft and abutting against the end faces of said one roller, said sealing means extending beyond said one pressure roller for contact With the end faces of said other pressure roller, and means positioned adjacent said one pressure roller and adapted to rotate the latter about the axis of said shaft and to swing about said axis said other pressure roller together with its frame support from said one position in which said rollers are engaged in superposed relation to each other to another position in which said pressure rollers are disposed in side-by-side relation to each other.

4. In a universal padder, the combination of engaging pressure roller means with an open tank into which one of said pressure roller means extends in one position of said pressure roller means in Whichl said roller means are disposed in superposed position to each other, said open tank being of such dimension as to accommodate thereinsaid pressure roller. means When. the lattery are shifted to another position, sealing means abutting laterally against the ends ofv said one pressure roller means and extending. therebeyond in contact -withthe adjacent pressure roller means andrmeans operatively connected to said pressure roller means, for moving the one roller` means about its axis and for moving the remaining pressure roller means about. said one roller means from said oneposition to. said other position inY Whichsaid pressure roller means are disposed in side-by-side relation in said. tank.
