Abstract
Abstract A high pressure water gun has a main conduit through which the high pressure water is directed which ends in a restricted nozzle for increasing the velocity of the water exiting therefrom. A cross-channel connects the main water conduit and a water dumping conduit which has a relatively low pressure outlet. The crosschannel has a floating valve positioned therein which is actuable between a seated and unseated position in a response to the movement of a pin valve. In turn, the pin valve is moved by a pivotably mounted lever under the influence of a force supplied by the cam surface of the handle lever.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
125 words
In a safety release for a high pressure water gun having a high pressure main water channel with a high pressure, high velocity blasting nozzle at the end, a water dumping channel with a low pressure outlet, a cross-channel connecting said main channel to said water dumping channel, a valve means disposed in said cross-channel having an open and a closed position for controlling the flow therethrough, a handle lever actuable by an operator to actuate said valve means and open the cross-channel, the improvement comprising that said valve means is a floating valve having means for rotating said valve means about its axis when the valve means is in its open position and thus under the influence of water issuing from the cross channel.
Claim 2
Dependent Claim
125 words
In a safety release for a high pressure water gun having a high pressure main water channel with a high pressure, high velocity blasting nozzle at the end, a water dumping channel with a low pressure outlet, a cross-channel connecting said main channel to said water dumping channel, a valve means disposed in said cross-channel having an open and a closed position for controlling the flow therethrough, a handle lever actuable by an operator to actuate said valve means and open the cross-channel, the improvement comprising that said valve means is a floating valve having means for rotating said valve means about its axis when the valve means is in its open position and thus under the influence of water issuing from the cross channel.
Claim 3
Dependent Claim
26 words
The safety release as claimed in claim 1 wherein said floating valve has a shoulder and said rotating means comprises a knurled pattern upon the shoulder.
Claim 4
Dependent Claim
46 words
The safety release as claimed in claim 1 further including means actuable by said handle lever for amplifying the force applied to said handle lever by a factor of at least 100 and applying this force to urge said floating valve means to its closed position.
Claim 5
Dependent Claim
103 words
The safety release as claimed in claim 3 wherein said actuable means includes a pivotally mounted lever which contacts said pin valve at its first end portion and cam means on said handle lever for engaging said pivotally mounted lever in point contact near its second end portion, wherein the handle lever and pivotally mounted lever are so dimensioned that a force applied to the gripping portion of said handle lever is amPlified and transferred by said cam means to said pivotally mounted lever and by said pivotally mounted lever to said pin with a total force amplification of at least 100 times.
Claim 6
Dependent Claim
136 words
A high pressure water gun having a high pressure main channel with a high pressure, high velocity blasting nozzle at the end, a water dumping channel with a low pressure outlet, a cross-channel connecting said main channel to said water dumping channel, a floating valve means disposed within said cross-channel having an open and a closed position for controlling the flow therethrough, means for rotating said valve means about its axis when said valve means is in its open position and, thus, under the influence of water issuing from said cross channel, a handle lever actuable by an operator and means actuable by said handle lever for amplifying the force applied to said handle lever by a factor of at least 100 and applying this force to urge said floating valve means to its closed position.
Claim 7
Dependent Claim
136 words
A high pressure water gun having a high pressure main channel with a high pressure, high velocity blasting nozzle at the end, a water dumping channel with a low pressure outlet, a cross-channel connecting said main channel to said water dumping channel, a floating valve means disposed within said cross-channel having an open and a closed position for controlling the flow therethrough, means for rotating said valve means about its axis when said valve means is in its open position and, thus, under the influence of water issuing from said cross channel, a handle lever actuable by an operator and means actuable by said handle lever for amplifying the force applied to said handle lever by a factor of at least 100 and applying this force to urge said floating valve means to its closed position.
