WATER-CONVE Y ER.
SPECIFICATION forming part of Letters Patent No. 431,542, dated July 8, 1890.
I Application filed May 1, 1890. Serial No. 350,126. (No model.)
To all whom it may concern:
Be it known that I, GEORGE W. BAILEY, of Brooklyn, county of Kings, and State of New York, have invented a new and useful Improvement in Water-Conveyors, of which the following is a specification.
In the drawings I have shown in Figure 1 a diagram of the arrangement of the various parts as preferably employed in carrying out my invention, and in Figs. 2 and 3 diagrams of modified arrangements.
The object of the invention is to convey water from a river or reservoir to a lower level without the necessity of cutting or tunneling the bank; and it consists in combining, with a siphon-pipe, certain mechanisms hereinafter more particularly referred to, whereby the air is kept exhausted from the bend of the siphon by means of power obtained from the falling water.
a is a body of water.
b is the bank of the river or reservoir containing the same.
0 is the level to which it is desired to convey the water.
(Z is a siphon-pipe dipping at one end into the water a and extending thence upward over the bank and downward to the lower level 0. By exhausting the air from this pipe the water will flow through it on the prin ciple of a siphon, but continued operation will cause the accumulation of air at the bend of the siphon to such an extent that finally it will fail to operate; and it is to provide for the removal of this air as fast as it accumulates which is the'object of my invention, as I will now proceed to describe, referring first to the arrangement shown in Fig. 1.
e is a hole connecting the interior of the pipe at the top of the bend with chamber f. \Vithin this chamber is placed a float g, which is connected by the stem 9', (passing through a stuffing-box in the wall of the chamber f), or in any other suitable manner with one of two electrical contact-points h 72/, so that when the float g falls the contact will be made between said points, and when the float g is raised the contact will be broken.
a is an air-pump adapted to exhaust air from the bend of the siphon-pipe.
j is an electric motor arranged to drive the air-pump.
by a turbine wheel at.
Z0 is a storage-battery which is connected with the electric motor by the wires Z Z Z so that when the current is closedin those wires the electric motor j will be operated to drive the air-pump so as to exhaust the air from the bend of the siphon. The wires Zand Z are connected, respectively, with the contactpoints h and h.
Electricity is stored in the storage-battery k by means of a dynamo machine m, driven The water for driving this turbine wheel is taken near the lower end of the siphon-pipe from the stream of water falling-within, the siphon-pipe cZ being tapped by a branch pipe 0, leading to the turbine for that purpose. 7
It is unnecessary to illustrate in detail the construction of the turbine or the dynamo or the storage-battery or the electric motor or the air-pump, because it will be understood that any ordinary construction of those mechanisms will answer the purpose.
The operation is as follows: When the siphon-pipe is in perfect operation, the water will rise up in the chamber f sufliciently to raise the float g and break the current of electricity by separating the contact-points h Under these circumstances there will be no current to drive the electric motor j, and consequently the air-pump will not opcrate. As fast as any air accumulates in the bend of the siphon-pipe, it will rise up into the chamber f, and the level of the water will fall therein until the float has descended far enough to bring the contact-points h and 72/ together, so as to close the current. This will start the electric motor j in operation 50 as to drive the air-pump and exhaust the air from the chamber f.. This operationwill continue until the air has been exhausted sufficiently to raise the level of the water and with it the float, so as to separate the contactpoints h and h. In this manner the airpump and electric motor will be required to operate only to a very slight degree, in order to keep the bend of the siphon free from the accumulationof air. At the same time an ample accumulation of electricitywill be maintained in the storage-battery k by the continuous operation of the turbine n and dynamo m.
In Fig. 3 I have shown a modified arrange ment to be substituted for the chamber f and mechanism for controlling the contact-points of Fig. 1, whereby the contact-points are located within the chamber f. f is a supplemental chamber connected with the top of chamber f. The float 9 is mounted on alever 9 which is provided with an arm 9 projecting up into the supplemental chamber f. An electrical conducting cross-head h is mounted on this arm, and the inside contactpoints h and h are electrically connected with the outside wires Z and Z. The pipe 2' connects the supplemental chamber f with the air-pump. When the air accumulates inthe chamber f, the float will fall and the current will be closed by contact between crosshead k and contact-points h h. This will start the electric motor and air-pump in operation. When the air is exhausted sufficiently from chamber f, the float will be raised by the water and lift the cross-headit off of the contact-points h 71., so as to break the current and allow the electric motor'and air-pump to stop.
In the modification of Fig. 2 the electrical apparatus is entirely dispensed with. The air-pump is placednear the turbine, as at 2", and exhausts the air from the chamber f through the air-tube p. The height of the water in the chamber f at the bend of thesiphon is made to control the air-exhaust as follows; q is a three-way cock arranged .to connect the air-pipepeitheP with the chamber f or with, the open air. The position of this cock is controlledby the stem 7', to which it is pivoted, and which is secured to the float g within the chamber f. When the float falls, it turns the cock so as to connect the tube 19 with the chamber f. When the float is raised-by thewater, it turns the cock so as to connect the pipe 19 with the open air, under which conditionsthe air-pump simply exhausts fromthe open air.
InFig. 2 I'have shown the siphon-pipe 'as discharging into alfunnel s,'by which it is de-- livered to the turbine. By this arrangement the turbine will receive the power of the whole stream, and from the turbine this power may be divided up and applied in any way required, only a'small fraction of it being required to operate the air-pump.
I do not desire to limit myself to the details of construction or arrangement so far as the the contact-points controlled by said float, the
air-pump, the electric motor, and the electric connections, substantially as described.
2. In combination, the siphon-pipe, the floatchamber, the float, the electric connections, means connected with the floatfor controlling the current, the air-pump, the electricmotor, the storage-battery, the dynamo-machine, and mechanism for communicating power from the flow, of water in the siphon to the operation of the dynamo-machine, substantially as described.
3. In combination, the siphon-pipe, an airpump arranged to exhaust air from the bend of the siphon, means for driving the air-pump by power obtained from. the flow of water in the siphon, and means whereby the operation of exhausting the air is controlledby the level of water at the bend of the siphon, substantially as described.
4. In combination, the siphon-pipe, the airpump, the electric motor, the electric circuit,-
contact-points in said circuit, and means whereby the contactof said points-is controlled by the level of water at the bend of the siphon, substantially. as described.
