To /r/ZZ m/mm/ t 711,614/ conce/v1,.-

Be it known that I, OSCAR HERMANN STAKE- MANN, a subject of the King of Denmark, and a resident of Ohristiansted, St. Croix Island, 5 Danish West Indies, have invented a new and Improved Apparatus for Raising Liquids, of which the following is a full, clear, and exact description.

My invention relates to a device for raising Io liquids, and is especially designed for use in raising water from wells or other sources where ordinary pumps cannot be worked by windmills and other power not available at the particular point at which the wells are situated. It will be especially valuable where other power is already located at some distance from the source of water. as that can be used for compressing the air employed in my apparatus. zo The main object of the invention is to provide for raising water by the use of compressed air.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding parts in all the figures.

Figure l is a longitudinal sectional view of a water-receptacle provided with a preferred embodiment of my invention. Fig. 2 is a 3o view similar to Fig'. 1 with the parts shown in different position. Fig. 3 is a sectional view on the line 3 3 of Fig. 1. Figs. 1 and 5 are sectional views similar to Fig. 1, showing the parts in two dierent positions; and Fig. 6 is a sectional view on the line 6 6 of Fig. 5.

10 represents a receptacle for water provided with an inlet 11 and an outlet 12, the latter being preferably provided with a pipe 13, by means of which the water is discharged from the receptacle and forcedh to any desired point. The inlet and outlet are provided with valves 14 and 15, respectively, which may be of any ordinary type, but are shown as flapvalves. They are so constructed as to be automatically opened and closed, according to the pressure upon their opposite sides. A guard 16 is provided for the valve l5 to cause the water to enter at the bottom thereof and protect the valve, as in ordinary cases.

The receptacle 10 is designed to be located at such 5o a position with reference to the source of water as to permit the water to readily flow into the receptacle through the inlet 11 and completely Iill it. In other words, the top of the receptacle should be below the level of the water in the well or the like from which the water is supplied. The receptacle is also provided with an inlet 17 and an outlet 18 for compressed air. The air is preferably supplied from a compressor operated from any desired source of power and is alternately introduced and discharged for the purpose of forcing the water from the receptacle through the discharge pipe 18 and' permitting the water to enter the receptacle through the inlet 11. Within the receptacle is located a tank 19. This is constructed of material having greater specific gravity than that of water, preferably metal, so that when the tank is filled with Water it will sink in the water of 7C the receptacle. Its sides and bottom, however, being constructed with water-tight joints it Will when not containing water iioat upon the water in the receptacle. This tank is provided with spacing devices 2O to keep its up- 75 per edge from coming into close contact with the roof of the receptacle when it is ioated by the water therein and to permit the Water to overflow its top edges and enter the tank when in this position. For the purpose of 30 emptying the tank after it is filled a siphon is provided. This comprises two vertical pipes 2l and 22, the latter extending through the bottom of the tank and below it, as shown at 23. The siphon is completed by a chamber 85 24, connecting the tops of the two vertical pipes and having an air-valve 25, which opens upwardly automatically when the pressure within is suflicient in order to permit the air to escape and closes by gravity or in any other ordinary manner under all other circumstances to prevent the admission of air to the siphon. Pivoted to the tank are a pair of levers 26. These levers are pivoted at their opposite ends to the wall of the receptacle, and acrossbar 27 connects them at a point between their ends. Upon this cross-bar is pivoted a bar 28, extending upwardly from the cross-bar in a general vertical direction. A second bar 29 is pivotally mounted on levers 33, substantially parallel to the bar 28, and isprovided with a projection 30 near its top. An arm 31 is pivoted to the bar 28 and normally rests against the bar 29 with its end 32 directly under the projection 30, so as to support the bar 29 and hold it in elevated position, as shown in Fig. 2. It will be readily observed that the vertical movement ofthe tank 19, to which the levers 26 are pivoted, will cause the reciprocation of the bars 28 and 29. However, I provide means for modifying the motion of these bars so that the bar 29 will not follow exactly the movements of the tank 19. The" bar 29 is pivotally mounted upon a pair of levers 33, which extend across the receptacle and are adapted to be engaged at the end by short levers 34, pivoted to the opposite wall of the receptacle. The levers 33 are themselves pivoted to the wall of the receptacle upon which the levers 26 are pivoted, so that the two pairs of levers at certain times are arranged parallel to each other. The short levers 34 are connected by links 35 to a lever 36, pivoted to the receptacle and having a depending arm 37,supportingacollar38,through which slides a rod 39, provided with two stops 40 and 41. Upon the lower end of this rod is a float 42, located-in the tank 19. 1t will be readily understood that the movements of the oat 42 will operate the short levers 34 so as to cause them to be placed in a horizontal position, as shown in Fig. 2, where they will engage the ends of the levers 33 when the latter are brought down upon them or to cause them to assume van inclined position where the levers 33 will miss them upon being lowered. The control of the bar 29 is also aided by other mechanism, which will now be described.

When the parts 28 and 29 are brought to their most elevated position, means is provided for holding them there, comprising a spring 43, having a projection 44 engaging' a head 45 upon the bar 29 and a curved eXtension 46 engaging a similarly-shaped extension 47 upon the upper part of the bar 28. It will be seen by reference to Fig. 2 that the coperation of the parts 45 and 47 and the spring 43 will cause the bar 29 to be locked in elevated position after it is once forced into such position by the arm 31 until the bar 28 is pulled downward sufficiently to tilt the spring 43 and force the projection 44 out of engagement with the head 45. n A lever 48 is pivoted to the receptacle, and its end is designed to be engaged by the lower portion of the head 45 for a purpose to be described. This lever is connected by a link 49 with another lever, 50, pivoted on a rod 51 and having links 52 and 53, connecting it with valves 54 and 55, which control the air inlet and outlet openings, respectively.

The lever 50 is controlled by a catch 56, pivoted to the bar 29 at the point 57, and having' a counterweigiht 58, which will float on the water in the receptacle.

The various parts of the embodiment of my invention which I have chosen for illustrating the principle thereof having been described in detail, I will now proceed to describe the operation of the device. Assuming the parts to be in the position shown in Fig. 1, it will be observed that the valves 14 and 55 are open and the valves 15 and 54 are closed. Consequently water from the supply can freely enter the receptacle, the air therein freely escaping through the pipe 18. As the water rises in the receptacle it will soon reach a point where the tank 19 will float upon it, and the tank will consequently be carried up with the level of the water until the spacing' devices 2() strike the roof of the receptacle, as shown in Fig. 2. As the tank rises it carries with it the bars 28 and 29, and when it strikes the roof the locking device 43 is brought into operation to lock the bar 29 in raised position. This operation will have no eiect upon the parts 48, 49, 50, 52, and 53, but as the counterweight 58 floats on and rises with the water the catch 56 will be brought up to the top of the lever 50, so that any downward motion of the rod 29 will force down the outer end of the lever 50. The rise of the tank, taking with it the oat 42,'will cause the short levers 34 to be brought out into horizontal position, but not until after the ends of the levers 33 have passed them in their upward motion caused by the motion of the bar 29. This description of the parts applies to the positions shown in Fig. 2. The water in the receptacle when the parts rst assume these positions will be atacertain level with respect to the tank 19, both upon the outside of the tank and in the tube 22. There is nothing so far to prevent'the entrance of water into the receptacle, and consequently the water will continue to enter and the air to escape until the water reaches the level of the top of the tube 22, when it will flow over through the tube 21 into the bottom of the tank. This provision for-the escape of the water from the receptacle into the tank, however', will not be sufficient to provide for all the water entering the tank at the inlet 11, and consequently the level of the water will continue to rise until it pours over the top edges of the tank. After this the water will continue to flow into the tank from above until sucient weight is provided to sink the tank in the receptacle, and whether this occurs before the water in the tank reaches its top or not is immaterial. When the water reaches the top of the tank both inside and outside, the air contained in the tubes 21 and 22 will have been compressed in the chamber 24 and the valve 25 will have opened automatically to let this air out, and consequently this chamber will be completely filled with IOO than that of the water in the tank.

lwater-and there will be a continuous body ofl water from the lower end of the tube 21 to the point 23, and consequently this structure can from this point act as a siphon after the water outside the tank recedes to a lower level When the tank 19 starts to sink, it will of course rlhe descent of the bar cause the locking device 44 to become disengaged from the head 45, and this will permit the bar 29 to descend after the bar 28 has dropped a certain distance. This descent, however, will soon be checked by the ends of the levers 33 coming into contact with the horizontal short lever 34, which are held in horizontal position by the float 42. The float is compelled to remain in an elevated position on account of the water in the tank 19. The pressure of the Water in the receptacle is not sufficient at this point to open the valve 15 or to close the valve 14, but it requires the introduction of air-pressure into the receptacle to change the position of the water-valves in this manner. This is accomplished by the descent by gravity of the bar 29, which descent may be assisted in any desired manner. 1t will be seen that the catch 56 bears down upon the end oi' the lever 50, and consequently forces up its opposite end, so as to force the valves 54 and 55 upwardly. This opens the former and closes the latter, so that air-pressure is now brought to bear upon the water in the tank, and the How of water into the tank is stopped by the shutting of the valve 14, while the water is permitted to flow out on account oi' the opening of the valve 15. The parts will now be in the position shown in Fig. 4. l/Vhether the tank 19 is resting on the bottom or not is immaterial, as further motion of this tank downward will only pull down the bar 28 and arm 31 without aifecting the position of the bar 29, and the amount of water in this tank is at the same time suliicient to keep the iioat 42 in its highest position irrespective of the position of the tank and to keep the short levers 34 in horizontal position, where they hold the levers 33, so as to prevent them from further downward motion. The parts will remain in this position while the water is running out or" the receptacle, and it will be readily understood that the level of Water in the receptacle will be lowered until it reaches the top of the tank without disturbing the condition of things in the tank. As the level of water outside the tank recedes from this position the Siphon formed by the parts 21, 22, and 24 will operate to maintain the same level in the receptacle and tank, the valve 25 being kept closed by the pressure above it, aided by gravity. When the level in the tank reaches such a point as to permit the float 42 to descend so as to bring the stop 40 into contact with the collar 38, the

short levers 34 will be caused to assume an inclined position and permit the levers 33 to descend in the position shown in Fig. 1. The fall ot the level of the water will lower the counterweight 58 and will cause the catch 56 to become disengaged from the end of the lever 50 and bring all the parts back to the position shown in Fig. 1, the head 45 acting upon the end of the lever 48 to close the valve 54 and open the valve 55 through the instrumentality of the parts 49, 50, 52, and 53. The high pressure in the receptacle will then be freely diminished on account of the opening of the valve 55. The excess of pressure behind the valve 14 will open it, and the valve 15 will be caused to close by the pressure in the pipe 13. The parts are now in their original position, as shown in Fig. 1, and the operation will be automatically repeated as long as compressed air is supplied to the pipe 17. rlhe catch 56 may also be operated by the rise and fall of the rod 28 and its connections with the rod 29, as will be readily apparent.

It will be readily understood that many of the connections and details which I have described and illustrated will be capable of modification and that such modifications fall within the scope of my invention.
