Claims Analysis
Total Claims: 5
Claim 1
Independent Claim
188 words
In a dredge having a pump; a sluice box; a distributor box having a front wall, a target plate fixedly mounted in the distributor box, said target plate substantially evenly distributing into the sluice box water and solids entrained in the water which impinge the target plate; and a flexible conduit having an inlet end and an outlet end, said conduit having an outer surface having a helical projection, said conduit being operationally connected to the pump; the improvements comprising: a flange mounted on said front wall of the distributor box, said flange having a bore sized to receive a flexible conduit within it, said bore having a helical indentation to receive the helical projection of the flexible conduit, the outlet end of said flexible conduit being threaded into the bore of the flange; a bore through the front wall of the distributor box sized and positioned so that the outlet end of the flexible coupling can project into the distributor box; whereby the distance between the outlet end of the flexible conduit and the target plate can be varied by rotating the conduit relative to the flange.
Claim 2
Dependent Claim
188 words
In a dredge having a pump; a sluice box; a distributor box having a front wall, a target plate fixedly mounted in the distributor box, said target plate substantially evenly distributing into the sluice box water and solids entrained in the water which impinge the target plate; and a flexible conduit having an inlet end and an outlet end, said conduit having an outer surface having a helical projection, said conduit being operationally connected to the pump; the improvements comprising: a flange mounted on said front wall of the distributor box, said flange having a bore sized to receive a flexible conduit within it, said bore having a helical indentation to receive the helical projection of the flexible conduit, the outlet end of said flexible conduit being threaded into the bore of the flange; a bore through the front wall of the distributor box sized and positioned so that the outlet end of the flexible coupling can project into the distributor box; whereby the distance between the outlet end of the flexible conduit and the target plate can be varied by rotating the conduit relative to the flange.
Claim 3
Dependent Claim
28 words
In the dredge as defined in claim 1, wherein the bore of the flange has an axis, and said axis forms an oblique angle with the front wall
Claim 4
Dependent Claim
35 words
In the dredge as defined in claim 1 in which the front wall of the distributor box has an inner and outer surface, said flange being mounted on the outer surface of the front wall.
Claim 5
Dependent Claim
30 words
In the dredge as defined in claim 2, in which the target plate is substantially planar and is mounted in the distributor box at an angle to the front wall.
