F. MORAS. DOUBLE KNEE SIPHON. APPLICATION FILED SEPT- 8} 1920.
Patented July 4,1922.
NETEE FERDINAND lVIORAS, OF SOI'vIT/IERFELD, GEBI/JIANY.
DOUBLE-KNEE SIPHON.
Application filed September 8, 1920.
To all whom it may concern:
Be it known that I, FERDINAND l TORAS, a citizen of the German Republic, and a resident of Sommerfeld, Germany, have invented certain new and useful Improvements in Double-Since Siphons (for which I have filed an application in Germany Dec. 18, 1918) ,of which the following is a specification.
This invention relates to a double knee siphon, the operation of which is started by forcing out the air from a vent pipe, provided on the siphon, and in which the discharge of the balance of water, otherwise remaining in the siphon, is effected by a .simple auxiliary siphon.
The operation of the siphon is started:-
by means of a push button, the air pipe of which does not open into the air space of the inlet leg of the siphon, said air space being under tension, but into that part of the vent pipe, in which the seal of balance water, which is to be forced out of the vent pipe, still remains. This arrangement has the very material advantage, that the pushbutton conduit serving for starting the operation of the siphon is not under the air tension, prevailing in the siphon, and further that the push-button can have coinparatively slight dimensions, as it will have to force out only a very small quantity of water and does not need to compress, for this purpose, the quantity of air present in the siphon to force out the water.
In the accompanying drawing, in which a double knee siphon is illustrated in connection with a flushing tank, a sectional view of the whole arrangement is shown.
Within the tank w the double knee siphon m with the vent pipe at, the auxiliary siphon h and the air pressure balance pipe 1", connecting the inletand outletlegs of the siphon with each other are arranged. The water-supply pipe to the tank is indicated by i, the inlet-valve by 'v, the floater of the same by s and its auxiliary inlet by 0. The air conduit Z with the pushbutton arrangement 9 serves for starting the operation of the siphon.
The operation of the described arrangement is as follows: Before starting the operation, the vent pipe h, the lower part of which is bent in such a manner as to form a water seal is filled in said lower part with water, whereupon water is permitted Specification of Letters Patent.
Serial no. 409,028.
to enter into the tank through the inlet valve v. The water ascends within the tank and accordingly enters also into the inlet leg of the double knee siphon until it overflows at the apex of such inlet-leg and forms in the lower-middle-knee of the siphon a main water seal, producing within the siphon a closed air space. hen the water ascends in the tank beyond the double knee siphon, the air within the latter is compressed in accordance with the progressing ascension of the water, until this compression has reached such a degree, that the water seal existing in the vent pipe at is forced out, whereby the air enclosed in the siphon is permitted to escape and accordingly the operation of the latter is started. The tank is now drained or emptied and the operation ot the siphon ceases, when the water in the tank has descended to the inlet opening of the siphon, so that air may again enter into said inlet opening. During the drainage of the tank the water not only flows through the whole siphon but takes its course also through the ventpipe, sui'hcient quantity of water still re maining in the locking part of the vent pipe at the close of the draining period. In order to safely retain this water seal in the vent pipe at the close of the draining period, the outside air entering into the inlet openof the siphon must be prevented from also escaping through the vent pipe there-- by carrying-the water from said vent pipe. For this purpose the air pressure balancing pipe 1* is provided. The latter eflects a balance of pressure within the siphon in so far, that at the close of each draining period the vacuum, which is produced within the siphon by the breaking of the water column, can be balanced or neutralized immediately not only from the inlet opening but also from the outlet opening or simultaneously from both openings, as the air entering in the inlet leg of the siphon may take its course through the air pressure balance pipe 1", to the outlet leg of the siphon, so that the escape of the air does not depend on the draining of the central part of the main siphon, which requires a certain period of time. If there was no air pressure balancing-pipe the vacuum would still be produced since on breaking of the water column in the siphon the water, which is not drained 01f, drops down from inlet and outlet legs of the siphon into the tank or into the middle part of the siphon respectively. The water, dropping back in said middle part, is drained off at the close of each siphoning period by means of the auxiliary siphon h. By the cooperation of the three elements, viz: ventpipe, air-pressure balance pipe and auxiliary-siphon, the siphon is again made ready nates in a push button casing 9. As described above the operation of the siphon is automatically started, when the water in the tank has reached a certain height or the air pressure in the siphon has reached such a degree, that the water seal in the vent pipe is forced out. Until the operation of the siphon was started, said water seal formed a resistance, which opposed the draining action of the siphon. Before the automatic draining sets in, this resistance can be overcome mechanically by increasing the air tension by blowing in air or by removing the water resistance in the vent pipe. For this purpose the conduit Zis connected to the air tension space or to the vent pipe respectively; in the latter case the connection is effected at a point, in said vent pipe where the water seal, which is to be forced out by means of the push button, is present.
As the vent pipe a has a comparatively small cross-sectional area, as compared with the main siphon, a small quantity of air will be sufiicient, to remove the water seal from the vent pipe and to hereby force the breaking of the water-column in the double siphon. It may be seen herefrom, that the push button casing does not require any large dimensions and that in spite of the small dimensions of the same a safe operation is warranted.
Having thus particularly described the nature of my invention, what I claim as new and desireto secure by Letters Patent of the United States is:
l. A double acting siphon,comprising two U-shaped members and a member connecting the lower end of their adjacent legs, said siphon being adapted to be operated by forcing out the air, in combination with the push button arrangement, adapted to effect the starting of the operation of said siphon, an air pressure balance pipe connecting the air spaces of said siphon with each other and serving to balance the airpressure within the siphon and an auxiliary siphon serving to remove the balance of water, accumulating in the connecting member of the main siphon.
2. A double acting siphon comprising two U-shaped members and a member connecting the lower ends of their adjacent legs said siphon being adapted to be operated by forcing out the air, in combination with a push button arrangement, adapted to effect the starting of the operation of said siphon, a vent pipe, adapted to remove the air from said siphon, before the operation of the latter can be started, an air conduit, connecting the casing of the push button with the vent pipe at a point in which in said vent pipe the water seal to be forced out is present and which point is situated close to the con-' nection of said vent pipe with the outlet leg of said siphon, an air pressure balance pipe connecting the air spaces of said siphon with each other andserving to balance the air pressure within said siphon and an auxiliary siphon serving to remove the balance of water, accumulating in the con necting member of the main siphon.
V In testimony whereof I afiix my signature.
FERDINAND MORAS.
