Abstract
A wedge-shaped gate valve element (12) is held by a portable apparatus (10) in proximity to a tool (14) for refinishing sloped surfaces (16) of the element (12). The element (12) is gripped by a vise (92) which, in turn, is rigidly mounted to a vise support (86). The vise support (86) is mounted on a frame (17) of the apparatus. A support surface (90) of the vise support (86) is suitably inclined to give an upper sloped surface (16a) of element (12) a desired orientation with respect to the refinishing tool (14) which is also held in position on the apparatus (10).
Claims8
A portable apparatus for refinishing a sloped surface of a wedge-shaped gate valve element, said apparatus comprising:
- a tool having a working surface mounted thereon by a swivel joint;
- frame means, said frame means comprising a first frame member lying substantially in a first plane and a second frame member lying substantially in a second plane, said second plane being substantially orthogonal to said first plane;
- carriage means for holding said tool, said carriage means being selectively positionable in said first plane of said frame means so that the position of said tool is selectively adjustable with respect to said second plane, said tool being held by said carriage so that said tool may be selectively pivoted about an axis parallel to a line formed by the intersection of said first plane and said second plane;
- vise means for holding said gate valve element so that said sloped surface thereof faces said tool;
- and,
- support means mounted on said second frame member and upon which said vise member is rigidly mounted, said support member having a support surface inclined at an angle with respect to said second frame member upon which it is mounted so that said sloped surface of said wedge-shaped gate valve element held in said vise means acquires a desired orientation with respect to said tool.
A portable apparatus for refinishing a sloped surface of a wedge-shaped gate valve element, said apparatus comprising:
- a tool having a working surface mounted thereon by a swivel joint;
- frame means, said frame means comprising a first frame member lying substantially in a first plane and a second frame member lying substantially in a second plane, said second plane being substantially orthogonal to said first plane;
- carriage means adapted to travel in said first plane of said frame means and to hold said tool so that the position of said tool is selectively adjustable:
- (1) with respect to said second plane;
- (2) with respect to a first axis, said first axis being parallel to a line formed by the intersection of said first plane and said second plane, said tool being pivotable about said first axis;
- (3) with respect to a second axis, said second axis being perpendicular to said first plane, said tool being rotatable about said second axis;
- and,
- (4) with respect to said first plane;
- and,
- vise means for holding said gate valve element so that said sloped surface thereof faces said tool, said vise means being mounted on said second frame member so that said wedge-shaped gate valve element held in said vise member acquires a desired orientation with respect to said tool.
