Friedrich Emil many Halver, Germany, asaignor to Krauss, Schwarzenberg, Ger- Application April 28, 1932, Serial No. 007,625 In Germany May 2, 1931 2 Claim.
This invention relates to linen wringing machines of the type in which the linen is received I in a compressible flexible bag located in an inflexible outer casing provided with a partly or 5 wholly perforated and removable cover and communicating with means for filling the space between the bag and the casing with a fluid under pressure, for instance water under pressure, this pressure being then used as agent for wringing m the wet linen enclosed in the said bag.
While in the original form of linen wringing machines of the before-mentioned type the compressible bag has at its top, where it is continually open, a circumferential exterior collar resting upon a circumferential interior shoulder of the casing, and the pressure acting not only between the casing and the bag, but also upon said collar, tends, therefore, to lift the collar and, by the intermediary of the same, also the cover of the casing, the packing formed by the said collar and the members between which it is enclosed is thereby detrimentally affected and may, under circumstances become leaky. The object of the present improvement of linen wringing machines of the kind stated is to obviate that possibility, and I attain this object by providing the compressible bag around its top with an everted gutter forming a downwardly open cuff, the outer circumferential portion of which is also subjected to the pressure of the fluid under pressure used for the wringing purpose, and which is, therefore, pressed against the oppositely located top portion of the casing wherebythe tendency of said fluid to lift the uppermost portion of the bag and with it the cover is practically reduced to zero. The invention is' illustrated diagrammatically and by way of example on the accompanying drawing on which Figure 1 is a vertical axial section. through a linen wringing machine improved according to my invention. Figure 2 is a vertical section through *a modification solely of the compressible bag. Figure 3 is a view similar to Fig. 1, showing another constructional form, and Figure 4 is also a view similar to Fig. l and shows still another constructional form of the machine. Figure 5 is a plan view showing a form of bayonet lock for the cover.
, Referring to Fig. 1, a denotes the casing and b is the compressible bag enclosed therein. It is a matter of course, that the outer diameter of the bag is smaller than the inner diameter of the casing, so that a tubular space q of a certain width remains which receives the fluid under pressure that is to act on the bag. The width of that space may be comparatively large, as in Fig. 1, or comparatively small, as in Figs. 3 and 4. In either case the rim of the bag is averted or rebent outwardly, as at b, b" in Fig. 1, these portions of the bag forming an inverted gutter, or so a downwardly open end respectively, the outer rim b" of which contacts closely with the opposite rim of the casing, and the uppermost portion 12' of which contacts intimately with the cover it which is provided with perforations for the escape of the liquid pressed out of the linen containedin the bag. It is suited to the purpose in view to provide for a separate support for the gutter or cuff, preferably in this way that the casing is provided with a circmnferential shoulder 8, as in Fig. 1.
fI'he cover may be held in position by a type of bayonet lock shown in Figure 5, wherein the cover d is provided at its circumference with regularly spaced notches d and the collar t is pro- 76 vided with correspondingly spaced lugs t. In order to place the cover on the casing, the cover is positioned to permit the lugs t' to pass upwardly through the notches cl and the cover is then rotated so that the lugs are out of registry with 80 the notches.
The rim 1)" of the inverted gutter or downwardly open cuff may be reinforced, as shown in Fig. 2.
In the example shown in Fig. l the casing 11 is extended upwardly beyond the cover 41 and forms there a receiver I for the liquid leaving the bag.
At one side of this receiver is a spout 1 through which the liquid flows away. In the modification shown in Fig. 3 the receiver t forms a separate member which overlaps with a downwardly directed socket d the rim of the vessel a and is connected therewith by bayonet-closures, as shown. The compressible bag b is of the same design as that in Fig. 1, but the cover d which in this constructional form is made integral with the receiver t is provided with a downwardly and inwardly directed flange d", the outer circumferential surface of which corresponds with the curvature of the uppermost portion 12' of the bag so that the surface of contact between the bag and the cover is enlarged and the tightness therefore still more improved.
In the further modification shown in Fig. 4 the cover is designed as a hood d having apertures u only where there is the spout i. There is in this constructional form no socket like d in Fig. 3, but the rim of the hood engages an enlargement at the top of the vessel and is coupled therewith by bayonet closures, as shown. In all other respects matters are the same as in Fig. 3, also as regards the flange d".
For the introduction of fluid under pressure into the tubular space q the vessel a may be provided with a valve 0 to connect it with a pressure pipe line w, as in Figures 3 and 4; a valve c is provided for draining ofi the pressure fluid. Or a special valve 0' of known manner may be arranged as in Figure 1, adapted to connect the pressure pipe line w to the tubular space q by means of the opening a or with the interior of the bag b by means of a hose w, or to connect the interior of the bag b by means of the hose w to the drain pipe w".
I claim:
1. In a linen wringing machine, the combination with an inflexible outer casing and a removable cover therefor, said casing being internally and abruptly enlarged at its upper end to form with the cover an annular channel; of a flexible bag within said casing and free therefrom except at its upper edge, said bag being open at the top nd the material of the bag at its upper edge being everted and forming an annular cufl spaced from the body of the bag and resting against the bottom wall of the channel, the space between the body of said bag and the cuff forming a pressure channel closed at its upper end whereby when fluid under pressure is admitted to the casing around the bag said cuff is forced outwardly to prevent leakage between the cuff and casing, and means to admit fluid under pressure to the casing.
2. In a linen wringing machine, the combination with an inflexible outer casing and a. removable cover therefor, said casing being internally and abruptly enlarged at its upper end to form with the cover an annular channel; of a flexible bag within said casing and free therefrom except at its upper edge, said bag being open at the top and the material of the bag at its upper edge being everted and forming an annular cufi' spaced from the body of the bag and resting against the bottom wall of the channel, said cuff being thickened on the side next the body of the bag to form a reinforcement, the space between the body of said bag and the cufi forming a pressure channel closed at its upper end whereby when fluid under pressure is admitted to the casing around the bag said cuff is forced outwardly to prevent leakage between the cuff and casing, and means to admit fluid under pressure to the casing.
