Abstract
Abstract A holder composed of rotatively adjustable sections or halves each adapted to detachably support a square, such as a framing square, and combining with the two squares to provide a protractor-like instrument capable of supporting the blades of the squares at different desired angles relative to one another for use in accurately lining up pipes preparatory to joining the pipes by welding. An outer side of each holder half is grooved to adjustably receive a blade of one of the squares which is clamped therein. The holder halves are capable of being clamped together in different rotatively adjusted positions for accurately positioning the other blades of the two squares at desired angles relative to one another.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
89 words
A square holder comprising two members, means rotatively connecting said members together in parallel relation to one another, said members having outer parallel surfaces each provided with an open ended groove therein to receive a blade of a square, means for adjustably clamping said squares in said grooves and means for adjustably securing said members together with said grooves and the blades received therein in different angularly adjusted positions relative to one another for positioning the other blades of the squares at different desired angles relative to one another.
Claim 2
Dependent Claim
89 words
A square holder comprising two members, means rotatively connecting said members together in parallel relation to one another, said members having outer parallel surfaces each provided with an open ended groove therein to receive a blade of a square, means for adjustably clamping said squares in said grooves and means for adjustably securing said members together with said grooves and the blades received therein in different angularly adjusted positions relative to one another for positioning the other blades of the squares at different desired angles relative to one another.
Claim 3
Dependent Claim
52 words
A square holder as in claim 1, said members each comprising a disc, one of said discs having a central opening, and a stud projecting perpendicularly from the center of the other disc and extending through and being turnably disposed in said opening and constituting said means for rotatively connecting the discs.
Claim 4
Dependent Claim
42 words
A square holder as in claim 2, said stud being threaded, and a nut threadedly engaging the stud and combining therewith to form said means for securing the discs together with the grooves in different angularly adjusted positions relative to one another.
Claim 5
Dependent Claim
59 words
A square holder as in claim 3, the inner face of one of said discs having a radially extending rib, and the inner face of the other disc having a plurality of radially extending grooves selectively receiving said rib for accurately positioning the blade receiving grooves of the two discs in different angularly adjusted positions relative to one another.
Claim 6
Dependent Claim
132 words
A square holder comprising two members, means rotatively connecting said members together in parallel relation to one another, said members having outer sides each provided with a groove to receive a blade of a square, means for adjustably securing said members together with said grooves and the blades received therein in different angularly adjusted positions relative to one another for positioning the other blades of the squares at different desired angles relative to one another wherein each of said members having a second blade receiving groove converging with the first mentioned groove thereof and disposed at a right angle thereto, said second grooves being of a different width than the first mentioned grooves for accommodating a square blade of a different width than the square blades accommodated in said first mentioned grooves.
Claim 7
Dependent Claim
132 words
A square holder comprising two members, means rotatively connecting said members together in parallel relation to one another, said members having outer sides each provided with a groove to receive a blade of a square, means for adjustably securing said members together with said grooves and the blades received therein in different angularly adjusted positions relative to one another for positioning the other blades of the squares at different desired angles relative to one another wherein each of said members having a second blade receiving groove converging with the first mentioned groove thereof and disposed at a right angle thereto, said second grooves being of a different width than the first mentioned grooves for accommodating a square blade of a different width than the square blades accommodated in said first mentioned grooves.
Claim 8
Dependent Claim
23 words
A square holder as in claim 5, said grooves of each member having open ends opening outwardly of marginal portions of said member.
