Improved Automatic Discharging and Flushing Siphon I John Merrill 4 Manchester Rd. Sheffield, Engineer, do hereby declare the nature of this invention to be as follows: — My object is to provide an automatic flushing siphon that will work with either sewage or water and more particularly in the discharge of bacteria beds and the like. To do so I construct a trapper siphon one- part of which is con¬ nected to an air chamber placed in or in connection with an automatic flushing cistern the discharge of which will cause the mam siphon to discharge. Dated this 21st day of July 1903. JOHN MERRILL. COMPLETE SPECIFICATION. Improved Automatic Discharging and Flushing Siphon I John Merrill 4 Manchester Rd. Sheffield, Engineer, do hereby declare the nature of this invention and in what manner the same is to be performed, to be particularly described and ascertained in and by the following statement : — My object is to produce an automatic discharging and hushing siphon that will work with either sewage or water and more particularly in the discharge of bacteria beds and the like. To do so I construct a trapped siphon one part of which is connected to an air chamber placed in or in connection with ail automatic hushing cistern, the discharge of which will cause the main siphon to discharge. The accompanying drawing shews two chambers or beds A and 13 with the siphon 0. C11. in A and the discharging cistern E in 13. Before putting into work, the siphon and discharging cistern require to be trapped as shewn at T and T11. This having been done, if the bed A be now filled, when the liquid reaches the foot of the bell or dome C air is locked up in C and C1 1 and this air becoming compressed by the incoming liquid in A serves to carry a head proportioned to the depth of the two traps T and T11. The bed A being filled & the flow shut off it can be discharged when required by filling the bed B. The top of the discharging cistern E is fixed at the level to which 13 is to be filled. When B is full the liquid flows into the cistern E which contains an air- chamber F and an automatic flushing arrangement D which operates when E is quite full. The liquid rising in E also rises in F & drives the air above the line T1 1 by means of the pipe P through the trap T. The cistern E being full the apparatus D, which may be any efficient automatic apparatus, discharges the l Price 8d.]
