Claims Analysis
Total Claims: 4
Claim 1
Independent Claim
138 words
A spray head for washing body fluids from the surfaces of spring guides comprising a cylindrical spray head body portion, a guide plug fixed within said body portion and having an axial bore and a frusto-conic surface adjacent one end of said bore, a liquid distributing manifold within said body portion and surrounding said guide plug, a plurality of jet nozzles in communication with said manifold and disposed with their axes intersecting at a point in space outside of a plane containing said nozzles, said point being on the axis of said bore, the diameter of said bore being substantially smaller than the diameter of a circle passing through said nozzles and of a size to permit free passage of a spring guide, and a fitting in said body portion adapted to engage a source of washing liquid.
Claim 2
Dependent Claim
138 words
