APPARATUS FOR EVACUATING FLUID FROM A CHAMBER BACKGROUND OF THE INVENTION I OBJECTS OF THE INVENTION It is, therefore, an object of the present invention to provide apparatus wherein a plurality of liquid containing chambers may be evacuated simultaneously by means of a pressure differential. Another object is to provide a method wherein a plurality of liquid containing chambers may be evacuated simultaneously by means of a pressure differential. These and other objects will be apparent from the following description.
BRIEF DESCRIPTION OF THE DRAWINGS FIG. 1 is a side elevation of the apparatus of the invention.
FIG. 2 is a plan view.
FIG. 3 is a cross section taken along the line 33 of FIG. 2.
DETAILED DESCRIPTION As shown in the drawings, the apparatus of the present invention comprises a chassis having a top 10a, bottom 10b, sides 10c and 10d, front 10e and back 10f, and provided with a plurality of recesses 11. A conduit 12 extends from within the chassis and terminates at or beyond the exterior surface thereof. The conduit passes through at least some of the recesses 11, preferably near the bottom of the recesses. The top of each recess through which the conduit passes is fitted with receiving means 13. The receiving means 13 comprises a flexible tubing having an annular flange 14 which extends beyond the circumference of the recess and rests upon the top 10a of the chassis 10. The receiving means 13 is also provided with a second annular flange 15 which contacts the interior wall 16 of the recess. The receiving means 13 is adapted to receive valve means 17 having member 18. When member 18 is in a vertical position, valve means 17 is open, and when member 18 is in a horizontal position, valve means 17 is shut. Adapter 19 comprising a hollow stem 20 connected to an open top cylinder 21 fits into the conduit 22 in member 18. Cylinder 21 is adapted to receive a cylindrical projection 23 at the bottom of chamber 24. When the cylindrical projection 23 of chamber 24 is inserted in cylinder 2], liquid in chamber 24 may be evacuated by applying vacuum to the exterior terminus 12a of conduit 12 or by applying pressure to chamber 24.
Alternatively, receiving means 13 may be eliminated and the valve means 17 made of such size as to be maintained in the recess by a press-fit or by adhesive means, e.g., glue.
