Portable outdoor shower device
BACKGROUND OF THE INVENTION 
     This invention relates to a portable outdoor shower and, more specifically, to a portable outdoor shower which may be filled initially with water, heated to a desired temperature, and suspended in a desired position for use without having to transfer heated water from one container to another. 
     The concept of a portable bathing shower suspended from a selected object is known. U.S. Pat. No. 4,151,616, issued to Larson, discloses a combination poncho and camping shower, comprised of water resistent fabric and water dispensing means. U.S. Pat. No. 3,675,251, issued to Ruscher, Jr., discloses a portable shower comprising, in part, a reservoir container, suspended above a showerhead container. U.S. Pat. No. 3,431,565, issued to Nelson, discloses a portable shower in which water is pumped into the shower container through a heat source. U.S. Pat. No. 2,052,420, issued to Peterson, discloses a portable shower bath suspended from a wall bracket, which suspension is adjustable in height. U.S. Pat. No. 1,577,038, issued to Kvitle, discloses a portable shower apparatus having a bucket-type container, having apertures in a spring release device centrally located on the underside of the bucket. U.S. Pat. No. 1,241,764, issued to Pritchett, discloses a suspended portable shower device wherein the primary container is collapsible. U.S. Pat. No. 1,167,190, issued to Lippincott, discloses a portable shower device in which water is heated by an electric heater. U.S. Pat. No. 1,011,113, issued to Button, discloses a shower having a reservoir divided into upper and lower compartments. 
     While all of the referenced prior art discloses shower devices which are, to some extent, portable or adjustable, all of said devices require that the water utilized be separately heated and then transferred into the device or, alternatively, heated by a device incorporated within the portable shower. 
     Accordingly, with the above cited prior art, the heat source itself, or a separate container for heating the shower water must additionally be transported, a situation not feasible in many outdoor camping or hunting situations. Additionally, the requirement of heating water in a separate container applicable to many prior devices creates potential hazard in transporting and pouring hot water from one container to another. 
     Further, in many hunting and camping situations, the only heat source available may be an open fire. 
     Accordingly, a need exists for a portable outdoor shower device capable of being filled with water, heated from a primitive heat source such as an open fire and suspended in an appropriate location for utilization, without requiring an exchange of water between different containers. Specifically, an optimal portable outdoor shower device must permit water to be heated within the device itself so as to obviate the necessity of transferring heated water from one container to another. 
     An optimal portable outdoor shower device must permit the water to be heated from a primitive heat source, such as an open fire or campfire, without damage to the device. 
     In many instances, the need for use of a portable outdoor shower device arises in situations where a separate or internal heat source is impractical, where transporting an additional container for heating water separately would create an undue hardship and where the only satisfactory heat source is primitive in nature, in the way of a campfire or other open fire. As noted, existing portable shower devices do not satisfy the above requirements. 
     SUMMARY OF THE INVENTION 
     This invention is directed to provision of a portable outdoor shower device which will permit utilization in remote areas not dependant on self-contained heat sources, or upon the necessity of separately heating water in a different container to be then placed in the device. 
     More specifically, this invention is directed to the provision of a portable outdoor shower device that is especially designed to be filled with water and heated, and utilized as a shower device, without the necessity of transfer of heated water. A more specific object is to provide a portable outdoor shower device not dependant upon an internal heat source. 
     An additional specific object of the invention is to provide a portable outdoor shower device which may be heated directly from a primitive heat source such as an open fire or campfire. 
     According to an important feature of the invention, the device consists primarily of a container for liquid comprised of an inflammable material, such as metal, which may be heated in direct contact with fire. 
     According to a further feature of the invention, the primary container has a generally flat, horizontally disposed underside, which permits the device to stand upright while being heated, whether placed above a fire on a grid or grill, on the ground directly adjacent to a fire, or within the fire itself. 
     According to a further feature of the invention, fluid flow, allowing water to pass from the invention into and through a showerhead is provided by a hollow cylinder horizontally aligned with the bottom of the container and extending through the vertical wall of the container. In order to provide as uniform a temperature as possible in the water flowing through the showerhead, the hollow cylinder portion of the within the container extends to a point approximately central to the bottom area of the container. This placement prevents initial delivery of water that is either too hot or too cold, which might be occasioned otherwise when the device is heated by setting it at the edge of a fire or other heat source where the heat is applied directly to only a portion of the container. 
     According to a further feature of the invention, flow of water from the container through the showerhead is regulated by a fluid flow control valve which is affixed to the hollow cylinder on the exterior of the primary container. This fluid control valve is placed in a shut position when the device is being heated and, after heating, while being suspended, and is opened by the person utilizing it, at the time desired. 
     According to a further feature of the invention, the primary container is fitted with a cover which is further secured by a cross member extending across the diameter of the primary container and holding the cover firmly against the primary container. The advantages of such a cover include allowing the water contained in the container to be heated more rapidly, and the prevention of spills when the container is being removed from the heat source and suspended, and during shower operations. 
     According to a further feature of the invention, the cover of the container has an aperture, through which a thermometer is inserted into the container in order to monitor the temperature of the water being heated for future shower use. The thermometer is of a type which allows it to be read externally of the container, while in monitoring position, and a further feature of the invention allows the thermometer to either be kept permanently in place during all operations, or to be removed and inserted only for monitoring purposes as may be, from time to time, desired. 
     According to a further feature of the invention, a means of suspending the invention is provided through an eye-bolt or &#34;padeye&#34; mounted on a cross member attached over the top of the primary container having a duel purpose of holding the cover to the primary container in place. The eye-bolt or padeye is positioned so that its opening is in a vertical plane permitting simple insertion of a rod, stick, hook, rope or other device for use in placing the device on the heat source, removing it therefrom, and suspending the device from a point vertically above the position of the shower recipient. 
     The above and additional features of the invention may be considered and will become apparent in conjunction with the drawings in particular, and the detailed description which follow.
