Abstract

Abstract Apparatus for applying weld metal to the interior surface of a housing for a dredge pump or the like at least a portion of which is noncircularly curved comprising a guideway extending substantially parallel to the surface and welding means movable along the guideway and adapted during such movement to apply weld metal to the surface. Adjustable brackets are preferably provided for mounting the guideway whereby all increments of the length of the guideway may be disposed substantially equidistant from the respective corresponding increments of the length of the surface. The guideway is preferably flexible enabling it to be bent or sprung into position substantially parallel to the surface. The guideway preferably has spaced apart means such as openings therein for attachment of the brackets thereto. The brackets may be adjustable in a direction toward and away from the surface and also transversely of that direction. The housing has a side opening and the brackets are preferably mounted on the housing at the edge of the side opening. The housing has bolt holes at the edge of the side opening and the brackets are preferably bolted to the housing through the bolt holes. When weld metal is being applied to the interior surface of the housing the housing is preferably disposed in position lying on its side with the side facing upwardly open and with the welder stationed within the housing. The structure is such that the space over the welder''s station is unobstructed affording the welder rapid and easy egress in the event of an emergency.

Claims Analysis

Total Claims: 7
Claim 1
Independent Claim 176 words
Apparatus for applying weld metal to the interior surface of a housing for a dredge pump or the like while the housing is lying on its side with an upwardly facing side opening, at least a portion of which interior surface is noncircularly curved in the horizontal direction, and which housing affords no homologous surface or edge suitable for guidance and control of welding means, the apparatus comprising a welding means support shaped homologously in the horizontal direction to said interior surface of the housing mounted over the exterior of the housing and welding means supported and located entirely by said support, the welding means having a supporting portion exterior of the housing and horizontally propellable along said support and having another portion extending through the upwardly facing side opening the housing to the interior thereof and adapted during movement of the welding means along said support to closely traverse said interior surface of the housing and apply weld metal thereto without the necessity of a welder working inside the housing continuously adjusting the welding means.
Claim 2
Dependent Claim 176 words
Apparatus for applying weld metal to the interior surface of a housing for a dredge pump or the like while the housing is lying on its side with an upwardly facing side opening, at least a portion of which interior surface is noncircularly curved in the horizontal direction, and which housing affords no homologous surface or edge suitable for guidance and control of welding means, the apparatus comprising a welding means support shaped homologously in the horizontal direction to said interior surface of the housing mounted over the exterior of the housing and welding means supported and located entirely by said support, the welding means having a supporting portion exterior of the housing and horizontally propellable along said support and having another portion extending through the upwardly facing side opening the housing to the interior thereof and adapted during movement of the welding means along said support to closely traverse said interior surface of the housing and apply weld metal thereto without the necessity of a welder working inside the housing continuously adjusting the welding means.
Claim 3
Dependent Claim 49 words
Apparatus as claimed in claim 1 in which adjustable brackets are provided for mounting the welding means support whereby all increments of the length of the welding means support may be disposed substantially equidistant from the respective corresponding increments of the length of said interior surface of the housing.
Claim 4
Dependent Claim 36 words
Apparatus as claimed in claim 2 in which the brackets have separate elements which are relatively adjustable in a direction toward and away from said interior surface of the housing and also transversely of that direction.
Claim 5
Dependent Claim 43 words
Apparatus as claimed in claim 1 in which the welding means support is flexible enabling it to be bent or sprung into position substantially parallel to said interior surface of the housing and has spaced apart means for attachment of the brackets thereto.
Claim 6
Dependent Claim 45 words
Apparatus as claimed in claim 3 in which the brackets are attached to the housing through bolt holes at the edge of the upwardly facing side opening of the housing and the welding means support has spaced apart openings for attachment of the brackets thereto.
Claim 7
Dependent Claim 38 words
Apparatus as claimed in claim 1 in which the space over the upwardly facing side opening of the housing is unobstructed affording a welder working in the housing rapid and easy egress in the event of an emergency.
