HARMON DE LEON MOlfSE, 0F SUMTER, SOUTH CAROLINA.

FLUSHING APPARATUS.

Specification of Letters Patent.

Patented Nov. 18, 1913.

Application filed August 6,-1912. Serial No. 713,668.

To all whom it may concern Be it known that l, HARMON DE LEON Moisn, a citizen of the United States, re-

siding at Sumter, in the county of Sumter and State of South Carolina, have invented certain new and useful Improvements in Flushing Apparatus, of which the follow ing is a specification, reference'being had to the accompanying drawing.

My invention relates to flushing apparatus such as commonlyemployed for flushing sewers and has for its object the elimination of the float heretofore employed together with the rubberball controlled outlet valve together with the usual by-pass for rescaling the stool when one is used.

My invention also consists more specifically of means whereby the inlet valve is controlled by the movement of the bell which forms an element of any of the well known forms of air bound siphons.

My invention further results in a greatly simplified structure of few parts, easy to manufacture in which all parts requiring renewal are eliminated.

The accompanying figure is a sectional view through a flush tank embodying my 7 invention.

While I show but one embodiment it is obvious that same may be constructed in a different manner without departing from the principle of construction herein claimed as new by me.

1 denotes tank of any suitable structure.

2 is the upper end of the discharge pipe, the lower end of which, not shown in the drawing, being any of the well known siphon forms, the lower end being returned upward to form a liquid trap.

3 is a movable bell attached in any suitable manner to the movable arm 4: which is pivoted at 5 to a suitable support 6. The upper extension of this arm forms the operating lever 7.

8 is the inlet pipe which enters the valve casing 9 at 10. r

11 is the outlet from the valve communicating with the tank, this being normally closed by the valve member 12.

13 is a space over valve 12 and it will be seen that the pressure from the supply pipe is always in this space normally thereby keeping valve 12 on its seat and preventing the entrance of liquid into the tank provided the space 14 is also filled with liquid this being accomplished by providing the bypass hole 15 and channel 16, said channel being in an adjusting screw 17 whereby its area may be varied.

18 is a release valve carried by stem 19 and so arranged that when pushed downward the liquid in the chamber 14 finds an 7 outlet through the opening 20. Stem 19 is suitably connected to the member 1 by means of a slot 21 or in any other manner whereby it may partake of the motion of member 4. 22 is a small hole in the air bound siphon on aoline with the bottom of the tank for V vthe purpose of permitting the liquid remaining in the tank below the level of the bell, discharging to form an after flow. If this hole were not provided water would always remain in the tank below the level 28 of the bell.

In operation, the tank being empty, the inlet pipe 8 and chambers 13 and 14 are all at the same pressure consequently valve 12 is closed. Handle 7 is moved to the dotted position 24 where it is held by spring 25 which slips over projection 26. This imparts a downward motion to stem 19 thereby opening valve 18 and releasing the pressure in chamber 14:. The pressure of the incoming liquid in 8 and 13 now acts upon the valve member 27, raises valve 12 from its seat thereby permitting the liquid to enter the tank. When the liquid reaches a height in the tank greater than the height of the trapped liquid in the air bound siphon, the tank discharges. During and especially at the end of the discharge period, a strong downward pull or pressure is exerted on the bell which accordingly moves from the position shown in the dotted lines which it occupies during the filling of the tank, to the position shown in the solid lines, this downward motion pulling the projection 26 from under spring 25 and at the same time restoring valve 18 to its seat, this closing chamber 14. The liquid now passing through the hole 15 reaches chamber 1 1 by way of the passage 16 and when the pressure in 14 is sufiicient the valve member 27 is forced downward and the incoming liquid shut off. The liquid remaining in the tank will gradually drain out through the hole 22, the tank remaining entirely empty until again put in operation.

While I have shown but one form of valve, it is obvious that any valve operating by the release of pressure on one side of the movable valve member may be employed. It is also obvious that any means of regulating the capacity of the by-pass may be employed, also that any form of actuating mechanism for the bell and valve and any means of interconnecting the two may be used.

Having thus described my invention I clai'mz- 1. In a flush tank, a liquid supply, a valve therefor, an auxiliary valve for causing said valve to operate, manual means for opening said auxiliary valve, detent means engaging said manual means to hold said valve open and means for automatically releasing said detent and reseating said auxili'ary valve.

2. In a flush tank, a liquid supply, a valve therefor, an auxiliary valve for causing said valve to operate, means for opening said auxiliary valve, detent means for holding said valve open and means, actuated by the discharge of water from the tank, for antomatically releasing said detent and closing said auxiliary valve.

3. In a flush tank, a liquid supply, a valve therefor, means for unseating' said valve to fill the tank, a detent engaging said means to retain the same in a tank filling position and mechanism, operated by the discharge of'water rom the tank, for releasing said detent and closing the supply.

In testimony whereof I hereunto affix my signature in the presence of two witnesses.
