Enovmm 1H; LAGILLARDIS 1 1 7 5 mwowfnen m Am; 8 1871 lSufcfmnsr -SnHUNS Ddu/a/r-QZ M550 IRUN??? J NITED STATES EDOUARD DE LAGILLARDAIE, OF LORIENT, FRANCE.
IMPROVEMENT IN SUCTION-SIPHONS.
Specification forming part of Letters Patent No. 117,750, dated August 8, 1871.
To all whom it may concern:
Be it known that I, EDOUARD DE LAGILLAR- DME, of Lorient, in the Empire of France, have invented certain Improvements in Suction -Siphons, of which the following is a speeiiication:
My invention relates to the combination, with a siphon-pipe, of a small reservoir and pipe, provided with a cock for the regulation of the admission of air put in communication with the water to be drawn off, the reservoir and siphonpipe con'imunicatiug with an air-tube; the object of the invention being to produce a sufficient suction to enable the siphon to draw off or raise large bodies of water.
Figure l is a side elevation of an apparatus em'- bodying my invention.
s is a siphon-pipe, and a is the reservoir or filler. rlhe ends of the two arms of the siphonpipe are immersed, the descending 011e being arranged vertically. The reservoir a communicates by the pipe b, provided with a cock, with the liquid to bc drawn oli'. The lower part of the reservoir a is fixed on a horizontal plane on a level with the highest part of the siphon. The tube e, for the passage of air, reaches from the upper part of the reservoir to the top of the siphon.
In making use of the apparatus, the reservoir a is first filled up, having' previously sluit the cock of the pipey 1), and the communication between the apparatus and the atmosphere is then cut ofi. The suction-siphon is then ready for working, and acts as soon as the cock is opened and a suction at each end of the siphon is produced, and, the liquid rising and passing over the bend of the siphon, a regular downward tlow is established. During the first phase the air in the siphon expands and enters the reservoir a, and a sudden lowering of the liquid level is occasioned, but as soon as it rises the air returns to the siphon and iningles with the liquid current and is impellcd downward. At the'other end of the siphon the liquid d rises in the reservoir a and the loss occasioned by the filling is replaced in a short time. By this means the suction-siphon is not emptied, and can even bear the introduction of a certain quantity of air. By shutting the descending-tube b of the reservoir, when the siphon is stopped working, it is always ready for afresh operation. In filling the siphon it is merel ya, necessary to determine a pressure in the appara-l tus sufiiciently ,Denit-le to enable the liquid to be y drawn off to rise to the top of theshort branch of the siphon. The flow ofthe liquid previously introduced in'to the reservoir a induces a state of pressure, which it retains as long as any liquid remains therein, since the summit of the siphon and the lower part of the reservoir are established on the same horizontal plane, bntfthereisinthe siphowndat the. opening of thetube communicating /ivitwthe' reservoir. a lower pressure than `that.: necessary to cause the iillin g. It is the difference between these pressures which regulates the current of air from the reservoir into the current of fluid and the limits of action of the siphon, which f latter is ldeterminedby the height ofthe fall, awnd that ofthe short arm ofthe siphon over the liquid d. The siphon acts like a water-machine and effects a direct suction, producing the same effects as a vacuum.
In place of a cock for regulating the admission of air into the apparatus, an automatic valve is to be preferred, set in motion by a iioat placed in the reservoir.
I claim as my inventionrlhe combination, with a siphon-pipe, s, of a small reservoir, a, and pipe I), provided with a cock for the regulation of the admission of air, the reservoir and siphon-pipe communicating by an air-tube, c, in the manner and for the purposes herein set forth.
