Brief Patent Description - Full Patent Description - Patent Application Claims
[0001] The invention relates primarily to the need for potable water for human consumption. Since severe weather conditions create circumstances beyond human control, we find ourselves denied the use of such necessities as potable water. For example: during the time of severe weather conditions such as hurricanes, tornados, snowstorms and ice storms, there could be a disruption of electrical power. The lack of electrical power causes the water pump, a domestic water distribution system, to shut down and cease to function. When the water pump stops, there will not be any water available from the system. Since water is essential to life, the lack of water can cause serious threats to human and animal life. When a device is available to solve this problem, the device could be a life saving device for humans and animals, such as pets and farm animals. [0002] The invention was developed and used to extract water from a dysfunctional domestic water distribution system. The invention is simple and easy to use. The invention is lightweight and can be used by anyone capable of reading and following the instructions. [0003] The invention has many applications in different areas, such as marine, recreational, agriculture, and more specific plumbing. The invention is usable in most circumstances that require the evacuation or siphoning of free flowing liquids. The marine industry may use it for bilging. The agriculture industry could use it for evacuation, siphoning or filling liquid tanks from lakes or ponds. The invention could be used to supply emergency water for livestock animals. The invention can be used as a water pump for recreational vehicles and particularly any campsite near a stream or lake by attaching a hose of any length. [0004] Plumbers will surely use the invention to restore the prime to dysfunctional domestic water pumps that have lost their prime. Plumbers will find the invention to be very useful, since no wrenches or reserve water are needed to restore an electrical water pump that has lost its prime. The plumber simply attaches the invention to the appropriate hose bib outlet and pull the handle and enough water will be siphoned into the pump to restore the prime. SUMMARY [0005] This invention is a hand operated water pump that can be attached directly to any standard domestic water distribution system hose bib outlet connection. The invention is used to siphon free flowing liquids from their source. Free flowing liquids can be water from a potable source such as a deep or shallow well, water and liquids not restrained under pressure. The invention is not recommended for use on municipal water systems. The invention is not recommended for liquids that may damage the pump. The invention is also capable of pumping air needed to inflate basket balls, soccer balls, car and bicycle tubes and any other devices containing an air bladder. Such an invention is a necessity when there is an emergency situation that demands water. [0006] The invention may be constructed of any length and diameter using suitable material such as PVC or metal. The invention is a cylindrical tube capped on both ends. One end of the cylinder has a pumping handle installed. The end of the tube opposite the handle has one inlet side and one outlet side. The handle end of the cylinder has a metal rod, with a handle attached, and the rod is inserted through the end cap into the cavity of the cylinder. The end of the rod that has been inserted into the cylinder has been attached with a piston and a sealing ring embedded in the piston to help create suction or vacuum. A pull of the handle creates a vacuum inside the cylinder while a push of the handle creates a pressure in side the cylinder. To coordinate and relieve the pressures inside the cylinder that have been created during the pumping action, backflow check valves are installed to the inlet side and outlet side of the cylinder. Pulling handle out of the pump will close the outlet side backflow valve and open the inlets side backflow. Pulling the handle out creates a vacuum inside the cylinder and the vacuum is filled with a siphoned liquid until the handle is fully extended. When the cylinder is full of liquid it is time to discharge the liquid. Pushing the handle into the cylinder will close the inlet backflow valve and open the outlet backflow valve which allows the liquid to be discharged as the handle is pushed into the cylinder. Repeating the push and pull of the handle will continue the siphoning and discharging until the needed amount of liquid is accumulated. DISCLOSURES [0007] This document is to assert and make records of an idea for a device that may result in a patent from the United States Patent Office. [0008] This idea is solely mine. This idea has not been the result of a conversation with another person. There has not been any material or financial support or input from another person under any circumstances. I have never seen such a device nor have I ever read any description of such device. I have never sold the device nor attempted to sell the device to another person. [0009] This device has been shown in part to employees of the local hardware. The purpose for the showing this device was to demonstrate what parts I needed to purchase from that store. The two local hardware stores are the ACE Hardware and the Fairhope Hardware, both store are located in Fairhope, Ala. I demonstrated the function of this device as a prototype model at the home of William D. Fearno near the Christmas Tree farm located on state road #9 in Fairhope, Ala. I demonstrated the function of this device to a neighbor next door to Marthanne Meyers at 7541 Ridgeline Ct West, Mobile, Ala. I do not know the name of this person but I can describe him as large, gray hair suffering spinal surgery. The date of these two demonstrations was 4 Jan. 2003. I demonstrated the device to an employee at Olde Tyme Seeds on Greeno Rd. Fairhope, Ala. [0010] While I was attempting to purchase parts at Rubber Hose of Mobile a representative of Irish & Associates overheard and listen to my conversation with a young tall employee of Rubber Hose of Mobile. The man was stocky build, blonde hair and wore kakki pants and green sweater. He asked a few questions about the device and the term "pd" which means "positive displacement" and I said I worked for a pump company and the date was 5 or 6 Jan. 2003. I could tell immediately he had knowledge about pumping devices. [0011] The device is a hand operated pump. The pump is used to evacuate or siphon liquids using a hand operated pump. The basic principle is to create a vacuum sufficient to siphon a liquid from its source. The ideal use is for homeowners and plumbers to use when there is a dysfunctional water distribution pump, usually due to the lack of electricity. The device is best used for free flowing liquids such as free flowing water sources and shallow or deep wells that with dysfunctional water pumps. The device is not recommended for use with municipal water systems. [0012] The operation of the device is simple. Attach the hose bib connector of the device to any standard plumbing hose bib outlet on a domestic water distribution system or free flowing water supply. A simple push and pull stroke of the device will create a siphon within the device to siphon water from its source and force it out through the outlet to any desire location. A garden hose may be connected to the outlet side to direct the liquid to a designated container any distance away from the device. [0013] This is a description of flowing liquids through the device and explain the operation of the parts. After the device has been attached to a hose bib outlet connection of a water system you simply push or pull the handle of the device. A pull stroke of the device will open the back flow valve on the inlet side of the device and at the same time close the back flow valve on the outlet side. As the handle is pull out it will created a vacuum inside the device sufficient to pull enough water into the pump and equalized the negative pressure inside the pump. When the pressure is neutralized the inlet back flow valve will close. When the pump full of water it is time to discharge the water by pushing the handle inward. Pushing the handle inward will create a pressure inside the pump that will close the inlet back flow valve and open the outlet back flow valve. When the outlet back flow valve is open it allows the water to be discharged through the outlet side of the pump as the pump handle is pushed inward to a complete discharged. A continued push and pull of the handle will allow the pump to discharge as much water as is desired. DESCRIPTION [0014] A hand operated water pump comprised of an elongated tube body tube body with a plunger shaft inserted through a hole in the end cap that encloses the end thereof. The said plunger shaft has a piston attached with a slightly smaller outside diameter than the inside diameter of said tube body to enable easy movement of said piston within the said elongated tube body. The said tube body is elongated sufficient to hold water. The said plunger shaft has a handle attached to one end of said plunger shaft while the end opposite the said handle has a piston attached with an annular groove cut into said piston to receive an annular sealing ring. The use of said annular sealing ring creates an airtight seal between the said piston and inside wall surface of the said tube body. The said plunger shaft with said handle and said annular ring attached is inserted into said tube body through a hole in the said end cap. The end of said tube body opposite the enclosed end cap is equipped with two diametrically opposed laterally extended open ports. Each of the said open ports has a backflow valve that is inserted directly inside the flow path of water as the water passes through the said water pump. The first of the said open ports is the inlet side of said tube body. The said inlet side of said tube body is equipped with a standard thread female garden hose attachment means that is complete with a moveable locking mechanism to facilitate the physical attachment of said pump to a standard thread male garden hose bib outlet or spigot of a dysfunctional domestic water distribution system and other liquid sources. The said standard thread female garden hose attachment means is an integral part of the said tube body lateral open port. The second of said open ports of the said tube body is the said outlet side of said tube body. The said outlet side of said tube body is equipped with a standard male thread garden hose outlet that is an integral part of said tube body to facilitate the attachment of a garden hose to said tube body outlet when a garden hose is needed to direct the flow of the discharge water and liquids away from the said pump. [0015] The said backflow valves are sensitive to pressure changes within the said tube body and the pressure changes will make said backflow valve either open or close alternately. The said inlet backflow valve is inserted directly within the inlet flow path of water while the said outlet backflow valve inserted directly within the outflow path of water. The said backflow valves will open and close alternately as pressure changes inside the said tube body. The pressure change inside said tube body is created by the movement of said plunger shaft in or out of said tube body. The out stroke of said plunger shaft will close the said outflow valve and decreasing the inside pressure of said tube body will open said inflow backflow valve devise and continue decreasing the pressure inside said tube body sufficient to siphon water from a dysfunctional domestic water distribution system or other liquids from their sources into the said tube body. The in stroke of said plunger shaft will increase pressure inside said tube body sufficient to close the said inlet backflow valve and increase the pressure inside the said tube body sufficient to open the said outflow valve device. The continued in stroke of said plunger shaft will discharge water or liquid from said pump. Repeating the in and out stroke of said plunger shaft will continue to discharge water or liquid until the desired amount of accumulation is acquired. The pump is equipped with a foot rest attached on the second end of the pump opposite the handle end to stabilize the pump during remote use. BACKGROUND [0016] The prior art in pumps is prolific in patents that disclose various types of air and fluid pumps that claim numerous unique features and configurations. Some of the most pertinent researched patents of prior art are patent numbers U.S. Pat. No. 6,497,560 B2 issued Dec. 24, 2002; U.S. Pat. No. 6,499,974 issued Dec. 31, 2002; U.S. Pat. No. 1,414,463 issued May 2, 1922; U.S. Pat. No. 2,557,139 issued Jun. 19, 1951; U.S. Pat. No. 5,230,611 issued Jul. 7, 1993; U.S. Pat. No. 4,975,028 issued Dec. 4, 1990; and U.S. Pat. No. 2,462,980 issued Mar. 1,1949. [0017] The use of hand pumps of various designs and configuration for pumping air into or out of inflatable objects are well established in prior art. Despite numerous designs and configurations that have been developed by prior art the basic principal remains constant, useful and limitless for developing new ideas. New technologies and present day materials make possible new methods of development, construction and manufacturing new pumping apparatus for present day use. This proposed pump is the result of these new technologies, materials and manufacturing processes based on new ideas. While many patents disclose pumps for evacuating and inflating air into objects, most of the prior art pumps are based on the familiar bicycle type pump. The fluid pump configuration patented by P. M. Grant, U.S. Pat. No. 1,414,463 issued May 2, 1922, is made to Grants idea to make it more useful, easier to use and more diverse in an emergency situation. These improvements are embodied in the proposed pump making the pump more useful and diverse in an emergency situation. Grants pump has one side port slip joint fitting making the joint generic at best. The side port opposite the slip joint fitting is a smooth open port making the smooth open port useless for attachments. The proposed pump is significant improvement over Grants pump in that it has a mechanical attachment means on both the inlet side open port and outlet side open port which makes the pump better suited for the intended purpose of the pump and that purpose is to be able to attach the proposed pump directly to a hose bib or spigot of a domestic water distribution system without the use of hand tools and makes the proposed pump an integral part of the water distribution system. The improvements to Grants pump are embodied in the proposed pump making the proposed pump more useful and easier to use in an emergency situation. [0018] The proposed pump is simplicity in design, constructed of non-corrosive materials and functionality are significant improvements over prior art. The most novel feature of the proposed pump, which is the primary claim for a patent, is that it has a hand operated moveable female attachment means which allows the pump to be directly attached to the hose bib or faucet of a disabled domestic water distribution system without the use of hand tools and the pump becomes an integral part of the domestic water distribution system. [0019] Another prior art pump is U.S. Pat. No. 4,975,028 issued Dec. 4, 1990 to Glen R. Shultz. The Shultz pump does have an attachment means that may be considered mechanical attachment; even though it is a slip joint fitting. However, this attachment means also is not specific enough in its method of attachment and is generic in use and does not have a true specific mechanical threaded attachment means for inlet or outlet purposes as in the proposed pump. [0020] U.S. Pat. No. 2,462,980 issued to S. W. Litt on Mar. 1, 1949 is a prior art fluid pump. The pumps patented to Grant and Litt are difficult to use because of their design using to many parts interiorly and exteriorly and do not mechanically attach directly to the object to be inflated, deflated or pump water. The Litt and Grant pumps are mechanically elaborate in their use and functionality while the proposed pump is the simplest form of mechanical use and functionality. Continue reading...
