Abstract
Abstract Bomb recovery and shield apparatus includes a cage shaped to slip over a bomb, and a clip in the cage adapted to engage the bomb and retain it inside the cage. The apparatus also includes and explosion-resistant tubular shell having an upwardly opening end and a post extending above the open end. The post supports a pulley, and a line reeved over the pulley is secured to the cage. A workman standing a safe distance from the bomb pulls the line to slip the cage over the bomb and thereafter guide the bomb into the shell. A remote-controlled lid with an open mesh screen can be closed over the open end of the shell after the bomb is safely inside.

Claims Analysis
Total Claims: 18
Claim 1
Independent Claim
96 words
Apparatus for moving a bomb and shielding its explosion, the apparatus comprising a shell having an explosion-resistant body with a hollow interior and at least one open end, a cage shaped to fit around the bomb and adapted to retain the bomb inside it, a support extending over the open end of the shell, guide means secured to the cage and coupled with the support for moving the cage around the bomb and cooperating with the support to provide guided movement of the cage and bomb through the open end of the shell to its interior.
Claim 2
Dependent Claim
96 words
Apparatus for moving a bomb and shielding its explosion, the apparatus comprising a shell having an explosion-resistant body with a hollow interior and at least one open end, a cage shaped to fit around the bomb and adapted to retain the bomb inside it, a support extending over the open end of the shell, guide means secured to the cage and coupled with the support for moving the cage around the bomb and cooperating with the support to provide guided movement of the cage and bomb through the open end of the shell to its interior.
Claim 3
Dependent Claim
20 words
Apparatus according to claim 1 in which the support comprises an elongated post secured to the body of the shell.
Claim 4
Dependent Claim
105 words
Apparatus according to claim 1 in which the guide means comprises an elongated tension line for releasably securing a first end of the line to the cage, and a sheave secured to the portion of the support over the open end of the shell, the line being reeved over the sheave with its second end extending to a point remotE from the shell and cage, whereby the line can be shortened by drawing it over the sheave to raise the cage and bomb over the open end of the shell, the line being paid out thereafter to lower the cage and bomb into the shell.
Claim 5
Dependent Claim
14 words
Apparatus according to claim 1 in which the shell is an open-ended tubular body.
Claim 6
Dependent Claim
19 words
Apparatus according to claim 1 including an openable and closeable lid for covering the open end of the shell.
Claim 7
Dependent Claim
14 words
Apparatus according to claim 5 in which the lid includes an open mesh screen.
Claim 8
Dependent Claim
35 words
Apparatus according to claim 4 including an openable and closeable lid for covering the open end of the shell, and in which the end of the shell opposite the lid includes an open mesh screen.
Claim 9
Dependent Claim
36 words
Apparatus according to claim 5 in which the lid pivots between its open and closed positions, and including a line secured to the lid for pulling the lid from its open position to its closed position.
Claim 10
Dependent Claim
30 words
Apparatus according to claim 8 in which the shell includes dogs under which the lid is moved to hold the lid in place over the open end of the shell.
Claim 11
Dependent Claim
15 words
Apparatus according to claim 1 including mounting feet secured to one end of the shell.
Claim 12
Dependent Claim
29 words
Apparatus according to claim 1 in which the cage includes a spring biased retaining clip in its interior adapted to engage the bomb and retain it inside the cage.
Claim 13
Dependent Claim
18 words
Apparatus according to claim 1 including a carriage, and means for releasably mounting the shell to the carriage.
Claim 14
Dependent Claim
28 words
Apparatus according to claim 1 including a source of a temperature-reducing medium, and means for delivering the temperature-reducing medium from said source to the interior of the shell.
Claim 15
Dependent Claim
13 words
Apparatus according to claim 13 in which the temperature-reducing medium is liquid nitrogen.
Claim 16
Independent Claim
210 words
A device for picking up a bomb having a substantially cylindrical shape, the device including an enclosure having an elongated outwardly opening slot formed in its bottom, the slot being bounded on opposite sides by substantially parallel walls, the enclosure also having an exterior retaining wall portion above the slot bounded at the bottom by the parallel walls which form the sides of the slot, the retaining wall portion having a hollow interior shaped to enclose the bomb and a bomb-receiving opening to the hollow interior above the open end of the slot, the bomb-receiving opening being shaped to pass over the bomb to contain the bomb in the hollow interior, the walls at the side of the slot being laterally spaced apart by a distance sufficient to allow the walls to slide lengthwise adjacent to the sides of the bomb as the enclosure passes over the bomb, the walls of the slot being spaced apart by a distance less than the diameter of the bomb so that the walls are closely spaced from the side of the bomb when the bomb is contained inside the hollow interior, and an elongated retaining member projecting into the hollow interior and adapted to engage the bomb and retain it inside the enclosure.
Claim 17
Independent Claim
210 words
