1 tes This device relates generally to attachments for water wells, and more particularly to a novel type of water lifting device for a shallow well or bored well.
The primary object of this invention is to provide a water lifting device for use in conjunction with wells, which does not require the constant running of a motor when water is being drawn therefrom.
A further object of this invention is to provide a water lifting device wherein water is elevated from a well to a water storage tank, and means are provided for constantly applying pressure within this tank, so that at any time water may be withdrawn from the tank, such as by means of pipes, without the necessity for a motor to be running while water is being so withdrawn, as is the case with conventional types of well pumps.
A further object of this invention is to provide a water lifting device which is completely automatic, so that a constant level of water will be maintained between minimum and maximum points, so that ordinarily no manual intervention is necessitated.
An even further object of this invention is to provide a water lifting device which may be used with both dug wells and bored wells.
Yet a further object of the invention is to produce a simple and inexpensive device and yet one which will be exceedingly effective for the purpose for which it is designed.
These together with other objects and advantages which will become subsequently apparent reside in the details of construction and operation as more fully hereinafter described and claimed, reference being had to the accompanying drawings forming a part hereof, wherein like numerals refer to like parts throughout, and in which:
Figure 1 is a vertical sectional view taken through the device, illustrating the use of my invention in conjunction with a shallow or dug well;
Figure 2 is a perspective view of the spider to be used in conjunction with my device for constantly urging the piston downwardly;
Figure 3 is a horizontal view of the bottom of the storage tank, taken substantially along the plane defined by reference line 33 of Figure 1;
Figure 4 is a side elevational view of my device, as it would be used in conjunction with a bored well; and
Figure 5 is an exploded perspective view of the piston and Water storage tank comprising a basic part of the present invention.
Referring now more specifically to the drawings, the numeral generally designates the storage tank comprising the present invention, illustrating the same mounted in or on top of a well 12, in Figures 1 and 4 respectively. A piston 14 is inserted into tank 10, to vary the air pressure within the tank. The piston 14 is elevated by drive means 16, and is urged downwardly by resilient means 18. A frame 20 supports the whole assembly.
aren't Patented Oct. 18, 1960 The water storage tank 10 is constructed of an open cylinder 22, having a water inlet pipe 24 connected to the bottom thereof, and a water outlet pipe 26, is connected to the lower end of the side wall of the tank. A foot valve 28 interrupts inlet pipe 24, and a check valve 30 interrupts outlet pipe 26.
Looking now more particularly at Figure 1, it may be seen that water storage tank 10 is located internally of a shallow dug well 12. The water tank is maintained in this position by means of inwardly extending brackets 32, upon which the tank rests and is bolted, and hangers 34, which extend upwardly from angle irons 36 connected about the upper end of tank 10. A pair of channel members 37 constitute a base for frame members 38. Extending inwardly from. the upper end of the members 37 are brackets 40, to which hangers 34 are adjustably connected, so that it may now be seen that tank 10 is firmly held in position within the upper portion of the well. A plate 41 is connected to the upper ends of frame members 38, and has a centrally located vertical opening 42 formed therethrough, into which is fitted a bearing 44 having a projecting collar 46 about the upper end. A shaft 48 is vertically, slidably journalled in bearing 44, and extends upwardly through plate 41, as well as downwardly itno water storage tank 10. At the lower end of shaft 48 is connected a piston which is constructed of a cylindrical-like member 50 having a circular side wall and flat top and bottom walls. A flexible gasket 52 having a downwardly bent flange portion is connected to the lower end of cylinder 50, and another gasket 47 is connected to the upper end thereof. Gasket 52 is connected by means of a plate 54 locking the flexible member 52 to the cylinder by means of bolt 56. The lower end of shaft 48 is threaded as at 49 and has a washer 53 connected near the end, so as to abut against a plate 55. Threaded portion 49 is connected to the upper end of cylinder 50' and, by means of plate 55 the flexible member 53 is connected to the cylinder.
An upwardly projecting post 58, see Figure 4, is connected to plate 41, and has a horizontal beam 60 connected at the upper end thereof. A grooved pulley 62 is rotatably mounted on beam 60. A strand 64 of wire or other strong material is disposed about grooved pulley 62, and has a stirrup 66 located at one end thereof, which stirrup is connected to the upper end of shaft 48. The other end of wire 64 is driven by means of winch 68, which is in turn driven by motor 70. Thus, it may be seen that when winch 68 is activated the wire 64 will be wound upon the winch, and thus shaft 48 will be elevated, elevating piston 14 therewith and causing a suction within tank 10 which will draw water 72 into the tank 12 upwardly through inlet pipe 24, and this water will be held in the tank by means of foot valve 28. The motor and winch 70 and 68 respectively may be supported by any suitable means, but are shown supported upon a table 74 which is mounted upon angle iron 76 which is attached to one of frame members 38, and a base member 78, which is also attached to one of frame members 37, and supports the outer end of the table 74 through the medium of a channel beam 80.
In Figure 2 is illustrated a spider 82. which is con structed of a sleeve 84 having radial arms 86 extending outwardly from the upper end thereof. The sleeve 84 is fixed upon shaft 48 by means of setscrew 88. At the outer ends of each arm 86 a longitudinally extending slot 90 is formed vertically through the arms. Strong springs 92 are adjustably fastened in slots 90 of arms 86 by any suitable means, such as by hooks 94 having a threaded shank passing upwardly through slot 90, which is fixed in place by a nut 96. The lower end of spring 92 is connected to loops or eyes 98 which are fastened to top plate 41.
The piston 14 is provided with any suitable type of limiting means which will automatically limit the uppermost and lowermost position of the piston, so that the piston will always be between a predetermined range, and the water storage tank will always have a predetermined amount of Water in the tank ranging between a set maximum and minimum. For instance, illustrated diagrammatically in Figure 4 of the drawings, may be seen an upper contact 102 and a lower contact 104, which are in such a position as to be contacted by projection 100 on shaft 48, upon upward or downward movement of the shaft. Wires from contacts 102 and 104 lead into control box 106 which is provided with suitable switches to control the operation of the motor 70, the switches being well known in the art.
In use, the machine when first set up, will be manually started, so that as piston 14 rises in the water storage tank, a suction is created which will tend to force water 72 in the well up into the storage tank. When the piston reaches a position near the top of the tank 10, the projection 100 will touch contact 102, and shut of]? motor 70, thus stopping the actuation of the winch 68. Then, as water is withdrawn by means of pipe 26, the water level in tank 10 will go down, and the piston will move downwardly accordingly, both because of its own weight, and because of strong springs 92 urging it downwardly. When the piston reaches a position close to the bottom of tank 10, projection 100 will touch contact 104 and the motor will be actuated which will drive winch 68 and serve to raise piston 14, until projection 100 again contacts element 102. Thus, the cycling will continue and the operation will be automatic. In this way, a motor 70 does not have to be constantly actuated in order for water to be withdrawn from pipe 26, as the case in conventional type of water lifting units. For instance, if water storage tank 10 were made to hold 150 gallons, and this amount were enough for a familys needs, for one day, it would be seen that the motor 70 would be actuated automatically once each day.
The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly all suitable modifications and equivalents may be resorted to, falling within the scope of the invention as claimed.
