It will be understood that the valve I3 is weighted sufficiently to cause a gravitating closing movement thereof.

It is believed the details of construction and manner of operation of the device will be readily understood from the foregoing without further detailed explanation.

Having thus described the invention,V what I claim is:

'1. A valve for ilush tanks comprising a. gravity actuated valve member adapted to control discharge of water from the tank and a dash-pot mechanism provided with a confined fluid and operatively connected to the valve for retarding movement of the valve.

2. A valve for ush tanks comprising a gravity actuated valve member adapted to control discharge of water from the tank and a dash-pot mechanism operatively connected to the valve for retarding movement of the valve, said dashpot mechanism comprising a cylinder, a confined fluid therein and a valved piston working in the cylinder.

3. A valvefor flushtanks comprising a gravity actuated rvalve member adapted to control discharge of water from the tank and a dash-pot mechanism operatively connected to the valve for retarding movement of the valve, said dash-pot mechanism comprising a cylinder having a confined iiuid therein, a by-pass connecting the upper and lower ends of the cylinder and a valved piston working in the cylinder adapted for free upward movement and retarded in its downward movement to delay closing of the valve member.

4. A valve for flush tanks comprising a, gravity actuated valve member, a stem rising therefrom, a cylinder having a piston working therein, a stem rising from the piston, a cross head connecting the valve stem and piston stem for uni- 'form movement, a by-pass connecting the upper and lower ends of the cylinder, a conned fluid in the cylinder, a passage through the piston and a valve in the piston adapted to close the passage upon a downward movement of the piston and vproviding free communication between the upper and lower portions of the cylinder upon upward movement thereof.

il 5. Alvalve for flush tanks comprising a gravity actuated valve member, a stem rising therefrom, a cylinder having a piston working therein, a stem rising from the piston, a cross head connecting the valve stem and piston stem for uniform movement, a by-pass connecting the upper and lower ends of the cylinder, a confined uld in the cylinder, a passage through the piston and Va valve in the piston adapted to close the pas- "sag'e upon a downward movement of the piston .and providing free communication between the upper and lower portions of the cylinder upon upward movement thereof and a manually adjustable valve controlling the by-pass.
