HYDRAULIC PUMP.
Specification of Letters Patent.
Patented June 30, 1908.
Application filed October 9, 1907. Serial No. 396,681.
To all whom it may concern:
Be it known that I, DON J. JARVIS, citizen of the United States, residing at Bissell, in the county of Stevens and State of Washington, have invented certain new and useful Improvements in Hydraulic Pumps, of which the following is a specification.
The present invention relates to an improved device for pumping or elevating water and is in the nature of a novel form of hy draulic pump designed to be submerged in a running stream so as to utilize the current of the stream to lift the water.
The object of the invention is to design a pump of this character which is of simple and durable construction and will utilize the energy of the stream to the fullest possible extent. 4
A further object of the invention is to pro vide novel means for mounting the pump whereby the same can be readily lifted to the surface of the stream when desired for the purpose of making repairs.
For a full description of the invention and the merits thereof and also to aquire a knowledge of the details of construction and the 1 means for effecting the result, reference is to be had to the following description and ac companying drawings, in which: a
Figure 1 is a perspective view of a hydraulic pump embodying the invention. Fi 2 is a longitudinal sectional view through the same. Fig. 3 is a detail view of the hood. Fig. 4 is an end view showing a modification. Fig. 5 is a top plan view of the modification shown in Fig. 4. Fig. 6 is a detail view of the device for causing the wings to operate alternately in the modified form of the invention shown in Figs. 4. and 5.
Corresponding and like parts are referred to in the following description and indicated in all the views of the drawings by the same reference characters.
Referring to the drawings the numeral 1 designates the casing which is designed to be submerged in a running stream and in the present instance is shown as supported upon a frame 2 by means of which it is held spaced from'the bed of the stream. An inlet opening 3 and an outlet opening 4 are formed in opposite sides of the casing, the inlet opening 3 communicating with a feed pipe 5 which extends up stream and terminates in a flared mouth 6. The upper portion ,of the casing 1 is ta ered and communicates with a chamber whic in the present instance is in the nature of an air dome 7, the communication between the casing and air dome being controlled by an upwardly opening check valve 8. In the preferred embodiment of the invention this air dome 7 is formed in two sections and is separated into an upper compartment and a lower compartment by means of a diaphragm 9 of some material such as rubber, the compartment above the diaphragm being filled entirely with air and operating in a well known manner to cause an even flow of water through the service pipe 10 which communicates with the lower compartment of the air dome.
The flow of water through the outlet opening 4 of the casing which faces down stream is controlled by an inwardly swinging door 11, the said door being hinged below the opening and being provided at its hinged end with a laterally extending arm 12 having a weight 13 applied thereto.
This weight normally operates to swing the door 11 down against the bottom of the easing so as to leave the outlet opening 4 unobstructed, and is adjustable upon the arm to permit proper adjustment to be made according to the velocity of the current. Pivoted at an intermediate point to the bottom of the casing 1 is a trip lever 14c, one end of which extends beyond the down stream face of the casing and carries an upwardly extending wing 15 adapted to partially close the outlet opening 4, while the opposite end of the said lever has a weight 16 adjustably mounted thereon, the said weight normally tending to swing the wing over the outlet opening. A vertically reciprocating plunger 17 is mounted in the bottom of the casing 1, the lower end of the plunger projecting under the casing so as to engage the trip lever 14 while the upper end extends within the casing and is adapted to engage the door 11 when the latter is swung downwardly against the bottom of the casing.
The current of the stream tends to produce a constant flow of water into the casing 1 through the pipe 5 and when the door 11 is in an open position the water flowing through the casing acts upon the wing 15 partially closing the outlet opening 4 and moves the said wing outwardly and away from the casing. This movement of the wing swings the up stream endof the trip lever 14 upwardly and operates through the plunger 17 to lift the door 11 until the same is caught by the current and swung upwardly so as to close the outlet opening 4..
the water transformed into pressure which.
lifts the check valve 8 and causes a portion of the water within the casing to enter the chamber constituted by the air dome 7. The internal pressure due to the momentum of the water within the pipe is thereby reduced until the weight 13 is sufficient to swing the door 11 downwardly and open the outlet 1. It will be readily apparent that the weight 16 of the trip lever will previously have lifted the wing into normal position over the outlet opening 4 and that the above described operation will be continuously repeated. It may be mentioned here that the plunger 17 is longitudinally adjustable, being formed of two telescoping sections and can be varied in length to obtain the best results according to the velocity of the current.
The up stream end of the feed pipe 5 is clamped between two strips constituting a cross beam 18, the ends of the cross beam being journaled in standards 19 anchored upon the bed of the stream. It will also be observed that the opposite end portions of the cross beam 18 are connected to corre-' sponding sides of the casing 1 by cables 20 extending along the opposite sides of the feed pipe. A cable 21 is also secured to the cross beam 18 and extends upwardly to a float upon the surface of the stream. The service pipe 10 is loosely connected by means of an elbow 22 to a lateral branch 23 extending to one of the standards 19. A
A slight modification of the invention is shown in Fig. 5 in which the casing 1 is shown as subdivided into a pair of compartments by means of a transverse partition 25, each of the said compartments being provided with an inlet opening communicating with a feed pipe 5 and with an outlet opening 4*. It will also be observed that the said casing 1 is provided at its upper end with a common air dome 7 communication between the air dome and compartments of the casing being controlled by the check valves. Each of these compartments is provided with a door 11 and trip mechanism therefor identical with that previously described, and the said mechanisms in the two compartments are designed to operate alternately. A pair of transversely disposed rock shafts 27 are ournaled upon the casing 1 between the upwardly extended ends of the trip leversl l". One end of each of the shafts 27 is extended laterally and curved as indicated at 28 so as to enter the corresponding opening 4* of the casing, while the opposite end of each of the shafts is provided with a crank portion 29. A spring catch 30 is provided for locking each of the upturned ends of the trip levers 14 in a raised position and the said spring catches are designed to be released through the medium of the cranks 29 when the shafts 27 are rotated. More specifically describing these spring catches it will be observed that the same are provided with beveled noses adapted to engage laterally projecting lugs upon the levers to'lock the forward ends of the said levers in araised position until released by the cranks 29. The various mem bers are so arranged that each of the trip levers 14: is locked in position until the door 11 of the opposite compartment closes and engages the laterally extending arm 28 of the respective rock shaft 27 and rotates the same to cause the crank 29 of the said shaft to release the catch. In this manner it will be readily apparent that the trip mechanisms within the two frames are caused to operate alternately. The up stream ends of the two feed pipes 5 are secured to a cross beam 18 having the ends thereof journaled between standards 19 similar to the previously described standards 19. It will thus be apparent that the casing 1 of the modification can be swung upwardly to the surface of the stream for making repairs or the like in a manner identical with that mentioned in connection with the previous form of the in vention. Should the stream carry much drift wood or like material it may be found desirable to provide the mouth of the feed pipe with a screen such as indicated at 26.
