APPARATUS FOR ELEVATING- WATER.

Specification of Letters Patent.

Patented May 16, 1911.

Application led June 4, 1908. Serial No. 436,587.

To all whom it may concern.:

Be it known that I, NAT H. FREEMAN, a citizen of the United States, residin at Boulder, in the county of Boulder and tate of Colorado, have invented certain new and useful Improvements in Apparatus for Elevating Water; and I do declare the followin to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which 1t appert-ains to make and use the same, reference being had lo the accompanying drawings, and to the letters and figures of reference marked thereon, which igorm a part ot this specification.

My invention relates to improvements 1n apparatus for elevating water through the instrumentality of a series of tanks or receptacles arranged one above another, the said tanks being connected with an air pump whereby the air may be exhausted and the water caused to rise in the tanks in response to the vacuum pull until the tanks are full in which event a valve is automatically operated in connection with each tank whereby communication with the air pump is cut ofie and the tank opened to the atmosphere, in which eventl the air pressure within the tank forces the water out and causes it to rise into the neXt tank, the lat-ter beinO' in communication with the air pump and so on, the water being raised from one tank to another, the dist-ance of the tanks above one another being properly regulated to take advantage of the principle that the weight of the atmosphere will cause the water to rise a certain distance the latter depending to some eXtentupon the elevation.

My present invention so far as its general features are concerned is substantially similar to the construction disclosed in my prior application Serial No. 419,558, tiled March 6th, 1908, but differs therefrom in the means employed for opening and closing the valves connected with the tanks or water receptacles whereby the said tanks are alternately open to the atmosphere and connected with the air pump for exhaust purposes according as it is required to cause the water to enter or pass out of the tank.

In my present construction I employ elec'- tro-magnetic means for operating the valves of the various tanks, provision being made in connection with each tank for closing one magnet circuit when the water has reached a predetermined level in the tank or when the latter is full, and another circuit closed when the Water has been driven outl of the tank through the weight' of the atmosphere. In one case the valve is operated to cut of communication with the air pump or suction pipe, and in the other case the valve is operated to open communication with the suction pipe and cut olf communication between the tank and the atmosphere.,I

Having briefly outlined my improved construction, I will proceed to describegthe same in detail reference being made to the accompanying drawing in which is illustrated an embodiment thereof.

In this drawing, Figure l is a side elevation of my improved apparatus illustrating two tanks and their attachment-s. Fig. 2 is a view of the construction showing two tanks in section and on a larger scale. Fig. 3 is a sectional View of an insulating box attached to the top of each tank and in which t-he contacts are located, whereby the circuits for operating the valve of each tank is controlled. In this view the parts are shown on a larger scale than in Figs. 1 and 2. Fig. 4 is a similar view showing the rod through whose instrumentality the circuits are controlled, in a dilferentrelative position from that shown in Fig. 3. Fig. 5 is a detail view showing the electro-magnetic means for operating the valves of the tanks, the valve mechanism being shown in section and the parts on a larger scale. Fig. 6 is a similar view showing the various parts of the mechanism in a different relative posit-ion from that shown in Fig.

The same reference characters indicate the same parts in all the views.

Let the numerals 5 and 6 designate two tanks arranged one above another. It must be understood that there may be any desired number of these tanks depending pipe and a pipe for introducing atmospheric air to thetmtank. When the valve is in the position lshown 1n Fig. 5, the passage 10 registers with an opening 14'formed in the valve casing and into which is screwed a short open-ended pipe 15 whereby air is allowed to pass into the tank; while when the valve 9 is in the position shown in' Fig. 6, the pipe 7 is cut off from communication with the atmosphere and placed in communication with a suction pipe 16 which is threaded into an opening 17A formed in the valve casing which opening re isters with the passage l2, the passage 10 eing closed or cut ott from communication with the atmosphere. These valves are operated through the instrumentality of a pair of electro-magnets designated 17 and 18 respectively. These magnets are of the solenoid type and their cores or reciprocating bars are designated 19 and 20 respectively. These bars are connected with the opposite extremities of a lever or rock arm 21 whose central portion is made fast to the stem 22 of the valve 9. As these magnets are alternately energized in the manner hereinafter explained, the valve is operated to bring the corresponding tank into communication with the atmosphere or the suction pipe as may be desired. The valve casing -as well as the electro-magnets, is mounted upon a stationary frame work 23 having a depending part 24 upon which is fulcrumed as shown at 25, a lever 26 whose opposite extremities are provided with projections 27 and 28. When the magnet 18 is energized, its bar 20 is moved downwardly and acts on the arm 29 of the lever 26 to cause its opposite arm 30 to move upwardly whereby the projection 28 is caused to engage two contacts 31 and 32, thus bridging the space between the said contacts and closing the circuit between two conductors 33 and 34, the latter leading to one terminal of the magnet 17 and the former leading to a contact screw 35 threadedy into the insulating box 46 mounted upon a tank 5 or 6 as the case may be. To the inner extremity of the screw 35 is attached a contact 36.

From the op osite terminalof the magnet 17 leads a conductor 37 to a pole 38 of an electric source 39, from whose opposite pole leads a conductor 40 to a conductor 41, one extremity of which is connected with a contact 42 threaded into an insulating box 46. To the inner extremity of this screw is attached a contact 43.

When the magnet 17 is energized, the bar 19 is moved downwardly (see Fig. 6) and caused to act on the arm 30 of the lever 26 whereby the projection 28 is disengaged from the contacts 31 and 32 and the contact 27 upon the opposite arm of the lever caused to engage two contacts 44 and 45 bridging the space between these two contacts and closing the circuit between a conductor 47 and a conductor 48. The conductor 47, leads to a contact screw 49 threaded into an insulating box 46. At the inner extremity of this screw is attached a contact 50.

Connected by the opposite terminal of a magnet 18, is a conductor 51, which leads to the conductor 37 connected with the pole 38 of a source of electricity 39 as heretofore explained.

Each tank is connected by means of a branch pipe 52 with a standpipe 53. Below each branch pipe 52, is a casing 54 in which is located a ball check valve 55.

In each tank is mounted a rod 56 whose lower extremity is slidably mounted in a hollow plug 57 while its upper extremity passes through an opening 58 formed in the central part 59 of a spider with which the top 60 of the tank is provided. Upon this rod is slidably mounted a hollow tioat 61. Made fast to the rod near the upper and lower extremitiesA thereof are two stops 62 and 63. As the water rises in the tank the ioat moves upwardly and when the water has reached a predetermined level in the tank, the float engages the upper stop 62 and as the water continues to rise, the ioat lifts the rod to the position shown in full lines in Fig. 4 and in dotted lines in Fig. 3 whereby its upper ball-shaped extremity' 64 is brought into engagement with the contact 50 and the upper extremity of the contact 43 within the insulating box 46 of the tank. When this occurs the space between the contacts -43 and 50 is bridged and the electric circuit is completed through the coils of the magnet 18. In this event thc path of the current may be traced as follows beginning with the contact 50: From the last named contact the current may be said to pass through the screw 49, the conductor 47, the contact 44 Aand thence through the projection 27, a contact 45, thence through a conductor 48 to one terminal of the magnet coil, and thence through a conductor 51 to a conductor 37, thence to the pole 38 of the electrical source 39 and thence from the opposite pole of the source through a conductor 40 to a conductor 41 and thence to the contact screw 42, to the contact 43 and through the ball extremity 64 of the rod to the contact 50 completing the circuit. As the magnet 18 is energized it acts to draw the bar 20 downwardly and this downward movement, acting on the arm 29 of the llever 26 depresses the last named arm and disengages the projection 27 from the con! tacts 44 and 45 thus breaking the magnet circuit. |This movement of the bar 20, however, due to the energizing of the magnet 18, acts to shift the valve 9 whereby its passage 12 is thrown out of communication with a branch suction pipe 16, while thc passage l0 is brought into communication with the atmosphere since the said passage is brought intol alinement with the short open-ended pipe 15. The water in the tank is caused to rise by virtue of the exhaustion of the air therefrom due to the tanks communication with a main suction pipe 65 through the branch suction pipe 16. As soon, however, as the water rises to the desired level in the tank as indicated in tank 5 (see Fig. 2), the valve is operated tovcut oli' communication with the suction pipe and open communication with the atmosphere, with the result that the pressure of the atmosphere upon the liquid 66 within the tank, forces the liquid out of the tank through the branch pipe 52 into the standpipe 53 and thence upwardly through the casing 54 opening a valve 55 and causing it to enter the tank 6 above through a branch pipe 52, and hence it will be understood that as the water is driven out of the tank 5 it rises in the tank 6 and when it has become lowered to the desired level in the tank 5, the float 61, engages the stop 63 on the rod 56, and causes the rod to move downwardly disengaging the ball 64 from the contacts 50 and 43 and bringing the said ball into engagement with' the contact 36 and the lower extremity of the contact 43. When this occurs the magnet 17 is energized and the path of the current may be traced as follows: From the Contact 36 through a screw 35, aconductor 33, to contact 31, thence through the projection 28 to the contact 32 and thence through a conductor 34 to one terminal of the coil of the magnet 17 and thence from the other terminal of the coil through a conductor 37' to the pole 38 of the electric source 39 and' thence through a conductor 40 to a contact screw 42 and thence` through the contact 43 and the ball 64 to the contact 36 completing the circuit. When this magnet 17 is energized, it acts to move the bar 19 downwardly whereby the lever 26 is actuated to disengage the projection 28 from the contacts 31 and 32 whereby the magnet circuit is broken. The downward movement of the bar 19, however, has been suficient by virtue of its action upon the lever 21, to shift the valve 9 whereby the passage 10 is cut oi from communication with the atmosphere and the passage 12 brought into communication with the branch suction pipe 16 whereby the water is again caused to rise in the tank 5 or 6 as the case may be.

It will be understood that as the water is expelled from the tank 5 it rises in the tank 6 and the float in the last named tank acting upon its rod 56, lifts the same to bring the ball 64 at the upper extremity of the rod into engagement with the contacts 43 and 50 of the tank 6 inthe same manner and with the same result heretofore described. In other words the tank 6 will by the operation of its corresponding valve 9 be open to the atmosphere and communication with the suc? tion pipe cut oli'. As the atmosphere enters the tank 6, the water will be expelled and caused to enter the tank next above and 4so on through the entire series of tanks until the water is raised to the desired height.
