This invention relates to an apparatus for taking out cream from milk containers. It consists of a small container of rigid or semi-rigid material with upwardly directed walls, open above and in the bottom, a valve adapted to close the bottom opening of the small container and bars or other means so connected with the container or the valvethat the container may. be manipulated and the valve opened and closed from a'placelocated outside the container; Preferably the apparatus consists of .a cylinder with bottom valve. The invention aims particularly at executing an apparatus or this kind insuch a way that the manufacture is simpleand reliable, while at the same time theoperation is satisfactory; Particular stress has been laidon producing the individual parts of the apparatus by stamping out from metal sheets. It seems then most convenient according'tothe invention to hinge the bottomvalve on the lower edge of the cylinder instead of having it fixed directly to a bar which can be moved up and down. Prefer- .ablythebottom valve is providedwi-th inclined projection which turns to the side in such a way that'it can be swung together with the valve proper by' the end of aneedle which slides along the cylinder at its outer end; The said projection is providedwith 'twoprotruding, horizontal pivotswhich get their bearing lug on the lower edge of the cylinder: The cylinder is split longitudinally and the split edges are bent outwards and backwards through about 180; The needle which serve s to open or-closethe valve is guided by a guideforming a channel which has arr-approximately circular, but open, section, and may be thread upon the split edges of the cylinder in such a way that it grips round same so a to close the cylinder along the split;

One embodiment is illustrated in the drawing, in which Fig. l shows a vertical-section through the apparatus. Fig 2 shows a cross section on the line 22 in Fig. 1, Fig. 3 an elevation of" the cylinder itself in unmounted state, Fig. 4 is a cross section onv the line .44..in Fig. 1, and Fig. 5 is a plan view of the bottom valve alone.

The cylinder is bent from a uniformly thick metal sheet, conveniently of brass, so that it assumes a cylindrical shape, split longitudinally at 2 (see Fig. 3). In this condition, the cylinder is somewhat larger than it will be when the various parts of the apparatus are assembled. The ,Split edges .of this cylinder are bent back approximately through 180, as shown at 3 in. Figs. 3

and 4, and corresponding. thereto a gu de 4 is used for the needle on rod 5', which operates. the valve. This guide 4 is also. bent together from a relatively long metal strip into an approximately cylindrical channel, as will be seen from Figs. 2 and 4. The longitudinal edges do not quite meet, and the distance between them is so "by its own weight.

In this state the. guide can be slid down along the-sides. of the. cylinder and will consequently close the cylinder-at thesplit .2, whereby theparts. assume themutual position shown in Fig. 4. The guide furthermore has a pair of members. band .I, ofwhich 6 isopen at the side, while l is perforated for the. penetration of. the needle .5. The latter is. passed by the cylinder I: and. .pro jects at 5':below the bottom-of the cylinder, where it is: adapted to act! iona tongue .8 projecting from the bottom valve 9. This is-a'lso. stamped out from sheet metal and is circular in shape so as to fit against the lower edge. of the cylinder 1 closed toward the guide 4.

This cylinder is at the bottom provided with two-bearing lugs ID for. projecting pivots i I. on the bottom valve 9. These bearing lugs: are in the unattached state-of the cylinder 1 at. such a distance from each other that it. is possible :withoutdifficulty to-pushthe pivots H into, po sition. But when the. cylinder 1- is closed by pushing down the guide t, the bearing lug l0 'wil'liibe moved so 'closely together that they will engageapproximately the-side edges: of the. proj'eotion a and thereby lock, the hinge connection between the bottom valve- 9: and: the cylinder 1 so as to preventremoval of the valve. This position :of'the bottom valve will be seen Fig. I- where the projection B- hasan inclined position downwardsrelatively to the horizontal bottom valve 9 In thev position shown in- Fig. 1', the end 5 0f the needl'epresses against the projection 82 and thereby keep the bottom valve 9 closed.

Ti on the other hand the end 5" of the needle is drawn up a little in its guide-bymeans of the ring handle at the top, the needle end 5" will release the projection 8, whereby the bottom valve 9 will swing down into a vertical position In this condition the apparatus can-be inserted into the top of" a milk bottle to a suitable depth, so that the top portion of cream enters; into the cylinder. t. Then the needle 5 is pushed down by means of the handle, so that the value is closed, whereupon the apparatu is lifted out with they cream.

The various. parts of the apparatus may also e pro uced .01" other materials than metal, viz. plastic, press material etc,

For sanita y p rp ses the apparatus is so designed. that the. individual partscan easily be taken apart for cleanin For the same. reason the use of closed pipes is avoided, which would havehad to be soldered or. welded the apparatus, whereby rests; of. milk. or cream. might easily pass up into the closed parts and get contaminated if an efiective cleansing were difficult or impossible.

the longitudinal edge portions adjacent said split,
