Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
135 words
A valve comprising a housing having a chamber, said chamber having an open top, a valve member comprising an elastometric plug adapted to be positioned in the chamber and to be removed therefrom, said plug having a flow-through opening therein, a handle connected to said plug for moving the same in a predetermined direction for opening and closing the valve, a top plate and a bottom plate for said plug, means associated with the plates for expanding the plug laterally, means mounting said handle on the top plate for a separate motion in a different direction, means forming a reaction member on said top plate, means associated with said handle applying stress to the top plate and the reaction means in one position of the handle during said motion, and thereby actuating the plug-expanding means.
Claim 2
Dependent Claim
135 words
A valve comprising a housing having a chamber, said chamber having an open top, a valve member comprising an elastometric plug adapted to be positioned in the chamber and to be removed therefrom, said plug having a flow-through opening therein, a handle connected to said plug for moving the same in a predetermined direction for opening and closing the valve, a top plate and a bottom plate for said plug, means associated with the plates for expanding the plug laterally, means mounting said handle on the top plate for a separate motion in a different direction, means forming a reaction member on said top plate, means associated with said handle applying stress to the top plate and the reaction means in one position of the handle during said motion, and thereby actuating the plug-expanding means.
Claim 3
Dependent Claim
27 words
The valve of claim 1 wherein said plug-expanding means tends to cause the plates to approach each other under influence of the handle in its separate motion.
Claim 4
Dependent Claim
31 words
The valve of claim 1 wherein said handle has a position releasing said reaction means to allow said plug to relax for application and removal thereof with respect to said housing.
Claim 5
Dependent Claim
20 words
The valve of claim 1 wherein said valve housing is open at the bottom, the plug closing the open bottom.
Claim 6
Dependent Claim
33 words
The valve of claim 1 wherein said valve housing is open at the bottom, the plug closing the open bottom, said top plate having a diameter greater than the diameter of said chamber.
Claim 7
Dependent Claim
61 words
The valve of claim 1 wherein said valve housing is open at the bottom, the plug closing the open bottom, said top plate having a diameter greater than the diameter of said chamber, and the bottom plate having a diameter at least as small as the diameter of said chamber so that it can pass through it and the open bottom.
Claim 8
Dependent Claim
84 words
The valve of claim 1 wherein said valve housing is open at the bottom, the plug closing the open bottom, said top plate having a diameter greater than the diameter of said chamber, and the bottom plate having a diameter at least as small as the diameter of said chamber so that it can pass through it and the open bottom, and an annular gasket on the top plate at the undersurface thereof facing the top opening through which the valve plug is inserted.
