Abstract
Abstract An enclosed, substantially bulletproof shooting booth for an individual shooter has a front shooting opening communicating with the interior of an elongated, substantially bulletproof firing tube extending from the booth. The end of the firing tube remote from the shooting booth is closed by a bullet backstop which deflects bullets fired from the booth and collects them in a trough of liquid. The booth, tube and backstop are of double-wall construction with a bulletproofing and noise-suppressing layer of sand between inner and outer walls. Each of the booth, tube and backstop can be at least partially prefabricated at a remote location and transported to a desired range site where they are installed above ground so as to form a space-saving, quiet, enclosed shooting range for an individual shooter.

Claims Analysis
Total Claims: 15
Claim 1
Independent Claim
100 words
A firing tube for use in a shooting range comprising a generally tubular liner of metal sheet material, and panels for forming an outer sleeve completely encircling said liner, said liner having stiffeners projecting outward therefrom for supporting said panels spaced from the tube of said liner leaving room for filler material between said sleeve and said tube, and said liner including laterally spaced, upright sidewalls, integral flanges bent inward from the upper portions of said sidewalls, respectively, and interconnected so as to form a ceiling and a floor plate for extending generally between the lower portions of said sidewalls.
Claim 2
Dependent Claim
100 words
A firing tube for use in a shooting range comprising a generally tubular liner of metal sheet material, and panels for forming an outer sleeve completely encircling said liner, said liner having stiffeners projecting outward therefrom for supporting said panels spaced from the tube of said liner leaving room for filler material between said sleeve and said tube, and said liner including laterally spaced, upright sidewalls, integral flanges bent inward from the upper portions of said sidewalls, respectively, and interconnected so as to form a ceiling and a floor plate for extending generally between the lower portions of said sidewalls.
Claim 3
Dependent Claim
98 words
A firing tube for use in a shooting range comprising a generally tubular liner of metal sheet material, and panels for forming an outer sleeve completely encircling said liner, said liner having stiffeners projecting outward therefrom for supporting said panels spaced from the tube of said liner leaving room for filler material between said sleeve and said tube, and said liner including laterally spaced, upright sidewalls, integral flanges bent inward from the lower portions of said sidewalls, respectively, a floor plate for resting on said flanges and a ceiling extending generally between the upper portions of said sidewalls.
Claim 4
Dependent Claim
98 words
A firing tube for use in a shooting range comprising a generally tubular liner of metal sheet material, and panels for forming an outer sleeve completely encircling said liner, said liner having stiffeners projecting outward therefrom for supporting said panels spaced from the tube of said liner leaving room for filler material between said sleeve and said tube, and said liner including laterally spaced, upright sidewalls, integral flanges bent inward from the lower portions of said sidewalls, respectively, a floor plate for resting on said flanges and a ceiling extending generally between the upper portions of said sidewalls.
Claim 5
Dependent Claim
118 words
A firing tube for use in a shooting range comprising an elongated, generally tubular inner liner, a plurality of stiffening frames spaced longitudinally of said liner and each closely encircling said liner, an outer sleeve having panels supporting on said frames so as to be spaced outward from said liner, and a layer of filler material between said sleeve and said liner and encircling said liner, and including a panel supporting plate attached to an edge of one of said stiffening frames remote from said liner so as to form a flange projecting longitudinally of said liner and spaced outward therefrom, a panel of said sleeve having an end margin engaged against the inner side of said flange.
Claim 6
Dependent Claim
118 words
A firing tube for use in a shooting range comprising an elongated, generally tubular inner liner, a plurality of stiffening frames spaced longitudinally of said liner and each closely encircling said liner, an outer sleeve having panels supporting on said frames so as to be spaced outward from said liner, and a layer of filler material between said sleeve and said liner and encircling said liner, and including a panel supporting plate attached to an edge of one of said stiffening frames remote from said liner so as to form a flange projecting longitudinally of said liner and spaced outward therefrom, a panel of said sleeve having an end margin engaged against the inner side of said flange.
Claim 7
Dependent Claim
101 words
A firing tube for use in a shooting range comprising an elongated, generally tubular inner liner, a plurality of stiffening frames spaced longitudinally of said liner and each closely encircling said liner, an outer sleeve having panels supported on said frame so as to be spaced outward from said liner, a layer of filler material between said sleeve and said liner and encircling said liner, and means for supporting said liner and said sleeve spaced above the ground, said liner and said sleeve having registered apertures through the bottoms thereof for forming a vent opening through the bottom of the tube.
Claim 8
Dependent Claim
101 words
A firing tube for use in a shooting range comprising an elongated, generally tubular inner liner, a plurality of stiffening frames spaced longitudinally of said liner and each closely encircling said liner, an outer sleeve having panels supported on said frame so as to be spaced outward from said liner, a layer of filler material between said sleeve and said liner and encircling said liner, and means for supporting said liner and said sleeve spaced above the ground, said liner and said sleeve having registered apertures through the bottoms thereof for forming a vent opening through the bottom of the tube.
Claim 9
Dependent Claim
38 words
The firing tube defined in claim 4, including a bullet deflector plate inclined upward generally from an edge of the aperture through the liner and extending laterally inside the liner throughout the entire lateral width of such aperture.
Claim 10
Dependent Claim
27 words
The firing tube defined in claim 4, including means mounted to the bottom of the sleeve adjacent to its aperture for drawing air from inside the liner.
Claim 11
Dependent Claim
21 words
A shooting range comprising a range master station and several elongated firing tubes extending generally radially from the range master station.
Claim 12
Dependent Claim
21 words
A shooting range comprising a range master station and several elongated firing tubes extending generally radially from the range master station.
Claim 13
Dependent Claim
65 words
The shooting range defined in claim 7, including a separate enclosed, substantially bulletproof shooting booth for each of the firing tubes, said shooting booths being connected, respectively, to the ends of the firing tubes adjacent to the range master station, each of said shooting booths having a rear window enabling a person at the range master station to see into each booth through said windows.
Claim 14
Dependent Claim

A firing tube for use in a shooting range comprising a generally tubular liner of metal sheet material and panels for forming an outer sleeve completely encircling said liner, said liner having stiffeners projecting outward therefrom for supporting said panels spaced from the tube of said liner leaving room for filler material between said sleeve and said tube, said liner including at least one longitudinally-extending welded seam and said stiffeners including corresponding stiffener plates each extending transversely of the length of said liner continuously and unbrokenly over said seam.
Claim 15
Dependent Claim
89 words
A firing tube for use in a shooting range comprising a generally tubular liner of metal sheet material and panels for forming an outer sleeve completely encircling said liner, said liner having stiffeners projecting outward therefrom for supporting said panels spaced from the tube of said liner leaving room for filler material between said sleeve and said tube, said liner including at least one longitudinally-extending welded seam and said stiffeners including corresponding stiffener plates each extending transversely of the length of said liner continuously and unbrokenly over said seam.
