Abstract
Abstract The invention relates to apparatus for use in aligning sections of pipe with respect to each other, and more particularly to aligning two sections of pipe 30 and 32 at a predetermined angle with respect to each other so that a joint between the pipe sections may be formed by welding and the like. The apparatus includes gauge devices 16 and 18 which slidably fit upon a leg 14 of a tool 10 having a second angularly oriented leg 12 such as a carpenter's square. Each gauge device includes a vertically movable gauge element 26 having gauge indicia 34 carried thereon. The gauge element 26 is advantageously in the form of a spring-loaded plunger which may be maintained within a bore 40 of the gauge device. Means for locking the gauge device in a spaced-apart relation is provided by wing nuts 22 and 24.

Claims Analysis
Total Claims: 8
Claim 1
Independent Claim
179 words
Apparatus for use with a square or like tool in angularly aligning first and second pipe sections for welding and joining of said pipe section in a desired angular orientation relative to one another, said tool being the type having a pair of angularly oriented legs, said apparatus comprising: a pair of gauge devices; means for slidably mounting said gauge devices to a first leg of said tool in a laterally spaced relation; each said gauge device including a vertically movable gauge element for engaging said first pipe section in said spaced relation while a second leg of said tool lies against said second pipe section; each said gauge element being independently movable in a vertical direction to provide a desired independent vertical displacement from the gauge device from which it extends and provides a measurement of said angular orientation; and indicia means carried on said gauge elements for indicating angular alignment of said pipe sections relative to one another so that a joint may be formed to fix said first and second pipe sections in said angular orientation.
Claim 2
Dependent Claim
179 words
Apparatus for use with a square or like tool in angularly aligning first and second pipe sections for welding and joining of said pipe section in a desired angular orientation relative to one another, said tool being the type having a pair of angularly oriented legs, said apparatus comprising: a pair of gauge devices; means for slidably mounting said gauge devices to a first leg of said tool in a laterally spaced relation; each said gauge device including a vertically movable gauge element for engaging said first pipe section in said spaced relation while a second leg of said tool lies against said second pipe section; each said gauge element being independently movable in a vertical direction to provide a desired independent vertical displacement from the gauge device from which it extends and provides a measurement of said angular orientation; and indicia means carried on said gauge elements for indicating angular alignment of said pipe sections relative to one another so that a joint may be formed to fix said first and second pipe sections in said angular orientation.
Claim 3
Dependent Claim
32 words
Apparatus as set forth in claim 1 including a bore formed in each said gauge device, each said gauge element including a spring-loaded plunger received in said bore bearing said indicia means.
Claim 4
Dependent Claim
51 words
Apparatus as set forth in claim 2 including a removable closure carried adjacent an end of said bore having an opening through which said plunger extends, said plunger being freely removable from said bore and closure for storage of said plunger in its entirety in said bore when not in use.
Claim 5
Dependent Claim
39 words
Apparatus as set forth in claim 1 wherein said gauge device includes a first member slidably carried by said leg and a second member removably attached to said first member, said gauge element being carried by said second member.
Claim 6
Dependent Claim
30 words
Apparatus as set forth in claim 4 including an extension member removably attachable between said first and second members facilitating use of said apparatus with pipe sections of different diameters.
Claim 7
Dependent Claim
23 words
The apparatus of claim 1 including lock means for locking said gauge devices in a desired position on said leg of said square.
Claim 8
Dependent Claim
24 words
The apparatus as set forth in claim 1 including lock means locking said gauge devices against lateral and longitudinal movement relative to said leg.
