Abstract A suction strainer, preferably for use in a dump and go tank such as used in firefighting, which, during liquid withdrawal, rests continually on the bottom of the tank so as to eliminate whirlpool and suction loss and which, when in place, has its intake immediately adjacent the bottom of the tank so that water can be withdrawn to a very low level in the tank. In one embodiment, a unitary coupling member rests in a shallow tray on the bottom of the tank and liquid in the tank is pulled past the tray, into the member via a mesh screen which removes foreign objects, and out the coupling member to a conventional firefighting hose which is connected to the coupling at a preset angle. In another embodiment of the invention, the member coupled to the hose is pivotably mounted to a guide plate which rests on the shallow tray and is fixed with respect to it, so that any antiswirl plates in the strainer always remain in parallel with the tank bottom regardless of the angle at which the dump and go tank is set.

Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
130 words
A suction strainer comprising: a shallow tray for resting on the bottom of a tank, a coupling member adapted to rest on said tray and having an opening in the bottom thereof adjacent said tray for withdrawing fluid from said tank so that said fluid can be withdrawn to a low level, means for coupling said member to a hose so that said hose receives said fluid from said member, and an interior passage for directing said fluid from said opening to said coupling means, and a stationary member pivotable connected to said coupling member so that said coupling member is pivotable about an axis substantially parallel with the bottom of said tank and substantially perpendicular to the direction which said fluid flows into said hose from said coupling means.
Claim 2
Dependent Claim
130 words
A suction strainer comprising: a shallow tray for resting on the bottom of a tank, a coupling member adapted to rest on said tray and having an opening in the bottom thereof adjacent said tray for withdrawing fluid from said tank so that said fluid can be withdrawn to a low level, means for coupling said member to a hose so that said hose receives said fluid from said member, and an interior passage for directing said fluid from said opening to said coupling means, and a stationary member pivotable connected to said coupling member so that said coupling member is pivotable about an axis substantially parallel with the bottom of said tank and substantially perpendicular to the direction which said fluid flows into said hose from said coupling means.
Claim 3
Dependent Claim
18 words
A strainer as in claim 1 further including a mesh screen covering said opening for filtering said fluid.
Claim 4
Dependent Claim
41 words
A strainer as in claim 1 wherein said coupling means is at one end of said coupling member, the height of said coupling member is greatest adjacent said coupling means and decreases continuously toward the other end of said coupling member.
Claim 5
Dependent Claim
19 words
A strainer as in claim 1 wherein said coupling means is a threaded tubular extension of said coupling member.
