Abstract

Abstract An alignment apparatus to be used with a light beam generator for alignment measurements in tunnel and pipeline construction and the like. The apparatus includes an adjustable support base for positioning the apparatus in an aligned position in the construction site. A support is provided on this base for the light beam generator equipment. The portion of the base to which the beam generator support is affixed is capable of pivoting about a first axis generally perpendicular to the intended beam path. A lateral offset is provided which is fixed on one end to pivot with the support base about the axis of the support base and is capable of supporting a rod at a displaced position from the support base wherein the longitudinal axis of the rod is parallel to the pivot axis of the base. A telescope may be mounted to the rod at a convenient position above the construction in order that the entire system may be aligned by visually aligning the telescope.

Claims Analysis

Total Claims: 12
Claim 1
Independent Claim 95 words
An alignment apparatus for a light beam generator used for construction measurement, comprising a rod; sight means for aligning said rod relative to a distant selected point, said sight means being rigidly positionable on said rod; a pivotal support defining a pivot axis, said pivotal support being positionable relative to the ground, said pivotal support including means for fixing the light beam generator relative to said sight means; and a lateral offset means for fixing said rod relative to said pivotal support at a laterally displaced position from the pivot axis of said pivotal support.
Claim 2
Dependent Claim 95 words
An alignment apparatus for a light beam generator used for construction measurement, comprising a rod; sight means for aligning said rod relative to a distant selected point, said sight means being rigidly positionable on said rod; a pivotal support defining a pivot axis, said pivotal support being positionable relative to the ground, said pivotal support including means for fixing the light beam generator relative to said sight means; and a lateral offset means for fixing said rod relative to said pivotal support at a laterally displaced position from the pivot axis of said pivotal support.
Claim 3
Dependent Claim 95 words
An alignment apparatus for a light beam generator used for construction measurement, comprising a rod; sight means for aligning said rod relative to a distant selected point, said sight means being rigidly positionable on said rod; a pivotal support defining a pivot axis, said pivotal support being positionable relative to the ground, said pivotal support including means for fixing the light beam generator relative to said sight means; and a lateral offset means for fixing said rod relative to said pivotal support at a laterally displaced position from the pivot axis of said pivotal support.
Claim 4
Dependent Claim 95 words
An alignment apparatus for a light beam generator used for construction measurement, comprising a rod; sight means for aligning said rod relative to a distant selected point, said sight means being rigidly positionable on said rod; a pivotal support defining a pivot axis, said pivotal support being positionable relative to the ground, said pivotal support including means for fixing the light beam generator relative to said sight means; and a lateral offset means for fixing said rod relative to said pivotal support at a laterally displaced position from the pivot axis of said pivotal support.
Claim 5
Dependent Claim 33 words
The apparatus of claim 1 wherein said sight means is a telescope, said telescope having a line of sight in a vertical plane common to the beam path of the light beam generator.
Claim 6
Dependent Claim 54 words
The apparatus of claim 1 wherein said pivotal support includes a cross brace, a journal operably attached to said cross brace, and a base support rod capable of being slidably positioned within said journal, said pivotal support thereby allowing pivotal movement of said base support rod about the axis of said base support rod.
Claim 7
Dependent Claim 23 words
The apparatus of claim 3 wherein the beam generator is capable of being rigidly attached to said base support rod to pivot therewith.
Claim 8
Dependent Claim 30 words
The apparatus of claim 1 wherein said lateral offset means includes a first socket capable of coupling with said pivotal support and a second socket capable of accepting said rod.
Claim 9
Dependent Claim 25 words
The apparatus of claim 1 wherein said lateral offset means is capable of positioning said rod parallel to the pivot axis of said pivotal support.
Claim 10
Dependent Claim 42 words
The apparatus of claim 1 wherein said lateral offset means is capable of positioning said rod relative to said pivotal support so that the lower end of said rod and the top of said pivotal support are in the same horizontal plane.
Claim 11
Dependent Claim 164 words
An alignment apparatus for a light beam generator used for construction measurement, comprising a rod; sight means for aligning said rod relative to a distant selected point, said sight means being rigidly positionable on said rod; a structural support member, said structural support member being rigidly positionable relative to the ground; a journal capable of being locked to said structural support member, said journal defining a vertical pivot axis when positioned to said structural support member; a base support rod capable of being slidably mounted vertically in said journal, said base support rod being capable of accepting the light beam generator; and a lateral offset including a first socket for fixing said lateral offset to the top of said base support rod and a second socket for accepting said rod, said lateral offset being capable of positioning said rod parallel to said base support rod whereby the bottom of said rod lIes in a plane common with the top of said base support rod.
Claim 12
Dependent Claim 164 words
An alignment apparatus for a light beam generator used for construction measurement, comprising a rod; sight means for aligning said rod relative to a distant selected point, said sight means being rigidly positionable on said rod; a structural support member, said structural support member being rigidly positionable relative to the ground; a journal capable of being locked to said structural support member, said journal defining a vertical pivot axis when positioned to said structural support member; a base support rod capable of being slidably mounted vertically in said journal, said base support rod being capable of accepting the light beam generator; and a lateral offset including a first socket for fixing said lateral offset to the top of said base support rod and a second socket for accepting said rod, said lateral offset being capable of positioning said rod parallel to said base support rod whereby the bottom of said rod lIes in a plane common with the top of said base support rod.
