Abstract
A siphon initiating device is provided having a cylinder member and slideably interactive hollow piston member, both members equipped with check valves to permit unidirectional flow. Both extremities of the device have threaded fittings for engaging garden hoses. By way of hand manipulated back-and-forth motion of the piston member within the cylinder member, a pumping action is initiated which fills the hoses with water, thereby initiating gravity flow of water through the hoses and initiating device.
Claims9
A siphon initiating device comprising:
- a) a cylinder member having a smooth internal bore elongated upon a straight axis between an open inlet extremity and an exit extremity containing means for engaging a hose;
- b) a first check valve disposed within said bore adjacent said exit extremity and adapted to enable liquid to flow from said bore unidirectionally out of said exit extremity;
- c) a hollow piston member having an open exit end and inlet end equipped with means for engaging a hose;
- d) sealing means disposed about said piston member in a manner to produce a substantially fluid-tight seal with said bore while permitting reciprocating sliding movement of said piston member within said bore;
- e) a second check valve disposed within said piston member and adapted to enable liquid to flow undirectionally through said hollow piston member, whereby
- f) said cylinder member and interactive piston member function as a pump which advances liquid through said device when said piston member is repeatedly manipulated back and forth within said cylinder member.
