Abstract
Abstract Apparatus is provided to move a fitting relative to a hole provided through the wall of a water main or the like. The apparatus includes a housing provided with an internal chamber communicating with the atmosphere through two openings. The housing is mounted on the water main such that a marginal portion of the housing about the first opening surrounds a fitting positioned in such hole. A pivotal member is sealingly mounted in the second housing opening for pivotal movement relative to the housing. A rod slidably penetrates a throughbore provided through the pivotal member, and has one end arranged to move toward and away from the hole. This rod end carries an adapter which may be engaged with a fitting. Thereafter, the rod may be selectively manipulated to move the fitting relative to the hole.

Claims Analysis
Total Claims: 6
Claim 1
Independent Claim
223 words
Apparatus for moving a fitting relative to a hole provided in a wall, comprising: a housing provided with a chamber therewithin and having a first opening and a second opening, each of said openings communicating said chamber with the atmosphere, a marginal portion of said housing about said second opening having a concave surface configured as a segment of a surface of revolution; mounting means adapted to secure said housing to said wall such that a marginal portion of said housing about said first opening will sealingly surround said hole; a pivotal member having a convex outer surface configured as a segment of a surface of revolution and provided with a through-bore, said pivotal member being sealingly mounted in said second opening such that said convex surface is arranged to face said concave surface to enable pivotal movement of said member relative to said housing about an axis normal to the axis of said through-bore; a rod sealingly and slidably mounted in said throughbore and having one marginal end portion arranged for selective movement toward and away from said first opening; and engagement means carried by said rod marginal end portion and adapted to engage a fitting; whereby when said engagement means is engaged with a fitting, said rod may be pivotally and axially manipulated to move said fitting relative to said hole.

Claim 3
Dependent Claim
52 words
The apparatus as set forth in claim 1 wherein said housing concave surface is configured as a segment of a spherical surface, and wherein said pivotal member convex surface is configured as a segment of a spherical surface, thereby to enable omnidirectional pivotal movement of said pivotal member relative to said housing.
Claim 4
Dependent Claim
37 words
The apparatus as set forth in claim 1 wherein said housing is provided a third such opening, and further comprising a transparent window mounted in said third opening to enable an operator to see into said chamber.
Claim 5
Dependent Claim
55 words
The apparatus as set forth in claim 1 and further comprising a cap mounted on said housing and having an opening aligned with said through-bore and said hole, and wherein a portion of said rod is arranged to penetrate said cap opening to position said rod in an aligned relationship with respect to said hole.
Claim 6
Dependent Claim
33 words
The apparatus as set forth in claim 1 wherein a plurality of recesses extend into said housing from a surface facing into said chamber, said recesses being adapted to receive and store fittings.
