Abstract
Abstract A support base has an attachment device for being secured in a predetermined position on a frame. A first coupler is mounted on the support base for movement in two mutually perpendicular directions and a first elongate member, is mounted in the first coupler and extends in a direction normal to the plane defined by the directions in which the the first coupler is movable. A universal coupling is disposed at the remote end of the first member and includes a second coupling and a clamp for securing the second coupling in any angular orientation relative to the remote end of the first member. A second elongate member is longitudinally adjustable and is fixed to the second coupling so that the remote end of the second member may be three-dimensionally adjusted relative to the remote end of the first member. A datum point is located in space relative to a stationary base by fixing the remote end of the second elongate member to a fixed element defining the point, clamping the other end of the second member to the upper end of the first member by means of the universal coupling, two-dimensionally adjusting the lower end of the first member relative to reference points on the base, and clamping the lower end of the first member relative to the base.

Claims Analysis
Total Claims: 12
Claim 1
Independent Claim
177 words
Apparatus for locating and securing a datum point in space relative to a support frame, the combination including: a support base having coupling means for securing the support base in various discrete positions on said support frame, first coupling means adjustably mounted on said base for movement in two mutually perpendicular directions, means for locking said first coupling means in discrete positions on said support base, first elongate means secured to said coupling means and extending in a direction perpendicular to the plane defined by said first and second directions, universal coupling means mounted at the remote end of said first elongate means and including a second coupling means and means for securing the second coupling means in any vertical and horizontal angular orientation relative to the remote end of the first elongate means, a second elongate means fixed at one end to said second coupling means and being extendably adjustable longitudinally whereby the remote end of the second elongate means may be positioned at a predetermined point in space relative to a point on said base.
Claim 2
Dependent Claim
177 words
Apparatus for locating and securing a datum point in space relative to a support frame, the combination including: a support base having coupling means for securing the support base in various discrete positions on said support frame, first coupling means adjustably mounted on said base for movement in two mutually perpendicular directions, means for locking said first coupling means in discrete positions on said support base, first elongate means secured to said coupling means and extending in a direction perpendicular to the plane defined by said first and second directions, universal coupling means mounted at the remote end of said first elongate means and including a second coupling means and means for securing the second coupling means in any vertical and horizontal angular orientation relative to the remote end of the first elongate means, a second elongate means fixed at one end to said second coupling means and being extendably adjustable longitudinally whereby the remote end of the second elongate means may be positioned at a predetermined point in space relative to a point on said base.
Claim 3
Dependent Claim
36 words
The apparatus set forth in claim 1 wherein said universal coupling means comprises a universal joint, said universal joint being mounted at the upper end of said first elongate means for rotation about the axis thereof.
Claim 4
Dependent Claim
64 words
The apparatus set forth in claim 2 wherein said universal joint includes first and second pins extending in mutually perpendicular directions, a first yoke means coupled to one of said pins and mounted on the upper end of said first elongate means and second yoke means engaging the second pair of pins and being mounted at the lower end of said second elongate means.
Claim 5
Dependent Claim
68 words
The apparatus set forth in claim 1 wherein said base includes first and second slide means, said first slide means being mounted on said base for movement in a first direction and said second slide means being mounted on said first slide means for movement in a second direction perpendicular to said first direction, said first coupling means being mounted on said second slide means for movement therewith.
Claim 6
Dependent Claim
36 words
The apparatus set forth in claim 4 wherein said universal coupling means comprises a universal joint, said universal joint being mounted at the upper end of said first elongate means for rotation about the axis thereof.
Claim 7
Dependent Claim
64 words
The apparatus set forth in claim 5 wherein said universal joint includes first and second pins extending in mutually perpendicular directions, a first yoke means coupled to one of said pins and mounted on the upper end of said first elongate means and second yoke means engaging the second pair of pins and being mounted at the lower end of said second elongate means.
Claim 8
Independent Claim
143 words
A method of locating a point in space relative to a fixed base point, comprising the steps of: vertically and horizontally adjusting the angle of a first elongate member relative to a second generally vertically extending elongate member, fixing the remote end of said first elongate member to a fixed element defining the point in space, adjusting the length of said first elongate member to bridge the gap between the fixed base point and the upper end of said second elongate member whereby said members have an angular orientation, securing the first and second members to prevent movement out of said angular orientation and two dimensionally adjusting the lower end of said second vertical member in a generally horizontal plane, and clamping the lower end of the second vertical member relative to a fixed support base after the two dimensional horizontal adjustment thereof.
Claim 9
Independent Claim
143 words
A method of locating a point in space relative to a fixed base point, comprising the steps of: vertically and horizontally adjusting the angle of a first elongate member relative to a second generally vertically extending elongate member, fixing the remote end of said first elongate member to a fixed element defining the point in space, adjusting the length of said first elongate member to bridge the gap between the fixed base point and the upper end of said second elongate member whereby said members have an angular orientation, securing the first and second members to prevent movement out of said angular orientation and two dimensionally adjusting the lower end of said second vertical member in a generally horizontal plane, and clamping the lower end of the second vertical member relative to a fixed support base after the two dimensional horizontal adjustment thereof.
Claim 10
Dependent Claim
84 words
The method set forth in claim 7 wherein the fixed point in space comprises a vehicle datum point, and including the steps of locating said vehicle on a frame, positioning said support base at a predetermined location on said frame, positioning the remote end of the first elongate member adjacent said datum point prior to securing said elongate members in said angular orientation whereby the position of said datum point in space will be located relative to a fixed point on said support frame.
Claim 11
Dependent Claim
76 words
The method set forth in claim 8 including steps of positioning said base in a predetermined location relative to a welding jig, and locking an element of said jig in engagement with the remote end of said first member to provide on said welding jig a mirror image of the point in space defined by the remote end of said first member whereby said first and second members and the angular orientation thereof can be duplicated.
Claim 12
Dependent Claim
68 words
The method set forth in claim 7 including steps of positioning said base in a predetermined location relative to a welding jig, and locking an element of said jig in engagement with the remote end of said first member to provide on said welding jig a mirror image of the point in space defined by the remote end of said first member whereby said fixture can be duplicated.
