Claims Analysis
Total Claims: 10
Claim 1
Independent Claim
76 words
An apparatus for supporting sporting guns having a gun barrel following test-firing intervals to effect a cooling of said gun barrel, comprising a frame and support means for supporting said sporting gun, said frame including a conduit extending in an inclined relationship to the ground for receiving at least said gun barrel and means for effecting a conducting of a gaseous cooling medium through said conduit and around said gun barrel to effect a cooling thereof.
Claim 2
Independent Claim
76 words
An apparatus for supporting sporting guns having a gun barrel following test-firing intervals to effect a cooling of said gun barrel, comprising a frame and support means for supporting said sporting gun, said frame including a conduit extending in an inclined relationship to the ground for receiving at least said gun barrel and means for effecting a conducting of a gaseous cooling medium through said conduit and around said gun barrel to effect a cooling thereof.
Claim 3
Dependent Claim
41 words
The apparatus according to claim 1, wherein said means for effecting a conducting of a gaseous cooling medium includes a blower driven by an electric motor connected to the lower end of said conduit for feeding said gaseous cooling medium thereto.
Claim 4
Dependent Claim
29 words
The apparatus according to claim 1, wherein said conduit gradually widens towards its upper end and has its inner side insulated by means of a heat-resistant, resiliently flexible material.
Claim 5
Dependent Claim
111 words
The apparatus according to claim 1, wherein said conduit is supported on a tubular frame member extending in an inclined relationship to the ground and supporting a support member for said sporting gun, said tubular frame member comprising a telescopically extensible and lockable tubular profiled rod carrying at its projecting upper end a pair of support members in the form of forks disposed at an angular spacing of 90°, one of said forks serving as a support member for a gun stock extending substantially in the direction of said gun barrel, and the other fork serving as a support for a gun stock extending at an angle to said gun barrel.
Claim 6
Dependent Claim
76 words
The apparatus according to claim 1, wherein said conduit contains a support for centering said gun barrel, said support comprising a U-shaped yoke having the ends of its legs secured to a pivot axle extending transversely of the longitudinal axis of said conduit, an intermediate portion of said yoke extending into said conduit and being bent into a V-shape for centering said gun barrel, with an apex of said V-shape being directed towards said pivot axle.
Claim 7
Dependent Claim
66 words
The apparatus according to claim 5, wherein said pivot axle of said centering yoke is connected to an adjusting lever adapted for pivotal movement between two limit positions, said adjusting lever having a cam, wherein a cam follower limit switch is provided having a cam follower engaged by said cam for energizing a blower in a limit position corresponding to the centering position of said yoke.
Claim 8
Dependent Claim
26 words
The apparatus according to claim 2, wherein said electric motor driving said blower is adapted to be energized selectively by ac current and dc battery current.
Claim 9
Dependent Claim
18 words
The apparatus according to claim 7, wherein said frame has an accumulator thereon of adequate capacity and voltage.
Claim 10
Dependent Claim
50 words
The apparatus according to claim 1, wherein said frame is movably supported on the ground by means of ground-engaging rollers and, in an open-air embodiment, by means of rubber-tired cross-country wheels of larger diameter, and is in addition configured as a tripod adapted to be stationarily supported on rubber pads.
