Abstract

Abstract Eye wash fountain apparatus which can be attached to a sink faucet without disturbing its normal use. When the need arises for irrigating the eyes and face of a worker due to an accident, the apparatus is quickly and easily swiveled into an eye-flushing position in which a valving arrangement diverts water from the sink faucet through the spray heads of the fountain.

Claims Analysis

Total Claims: 6
Claim 1
Independent Claim 297 words
An eye wash fountain for mounting on a sink faucet comprising: a valve body having a normally fixed portion and a swivel portion pivotally attached to said fixed portion, said fixed and swivel body portions having major flat abutting surfaces in a plane perpendicular to the axis along which said body portions are pivotally attached, and a pair of spray heads rigidly connected to said swivel portion of said valve body by two conduit means adapted to position said spray heads in a forward eye-flushing position or a back out-of-use position, said fixed body portion having an inlet channel connectable to a sink faucet and passing straight through said fixed body portion with the outlet end of said inlet channel lying in said abutting surface of said fixed body portion, and said swivel body portion having first and second outlet channels, said first outlet channel passing straight through said swivel body portion with the inlet end of said first outlet channel lying in said abutting surface of said swivel body portion, said first outlet channel being alignable with said inlet channel when said spray heads are in said out-of-use position and thus aligned directed to pass water straight through said valve body for normal faucet use, and said second outlet channel passing through said swivel body portion in a Y-shape with the inlet end of said second outlet channel lying in said abutting surface of said swivel body portion and the two outlet ends of said second outlet channel being connected to said conduit means of said spray heads, said second outlet channel being alignable with said inlet channel when said spray heads are swiveled into said forward eyeflushing position and thus aligned directed to divert water from said inlet channel to each of said conduit means.

Claim 3
Dependent Claim 43 words
Apparatus according to claim 1 wherein the inlet end of said inlet channel is threaded to receive and connect to the threaded nipple of a sink faucet, and the outlet end of said first outlet channel is threaded for connecting to an aerator.
Claim 4
Dependent Claim 29 words
Apparatus according to claim 1 comprising an O-ring retained in a groove in said abutting surface of said fixed body portion surrounding said outlet end of said inlet channel.
Claim 5
Dependent Claim 69 words
Apparatus according to claim 1 wherein said fixed and swivel body portions are each a flat symmetrical member with two parallel major flat surfaces, said fixed and swivel body portions having alike, symmetrical, non-circular perimeters defining the edges of said members bounding said surfaces so that said edges are in true alignment only in said out-of-use and eye-flushing positions which are spaced 180 degrees apart around said pivotal axis.
Claim 6
Dependent Claim 39 words
Apparatus according to claim 4 wherein said inlet and first outlet channels are along axes parallel to said pivotal axis and said two outlet ends of said second outlet channel lie in an edge of said swivel body portion.
