| 20100077625 | Professional Layout Tool - An all-in-one combination layout tool is provided for marking center lines for spacing studs, marking rip lines, marking cut lines for roof rafters and staircase stringers, and other purposes. The tool comprises a rectangular base plate, an elongate locator bar with a rounded pivot corner, and two connectors to connect the locator bar to the base plate in a variety of configurations. The base plate includes multiple “pivot” points for pivotally connecting the locator bar, two strategically-placed arcuate slots for marking or making angle cuts, and two strategically placed parallel slots for configuring the tool to mark or make rip cuts. Angle markings are provided on two adjacent edges of the base plate, and 1/16-inch markings are provided on the opposite adjacent edges. The base plate is planar and has no enlarged flange or lip that would hinder its use in laying out staircase stringers. | 04-01-2010 |
| 20110078913 | SCALE COUPLING SYSTEM - A collection of couplers and a corresponding coupling method that removably connect existing forensic scales to create a coupled scale, wherein a ruler arm of each scale is slidingly engaged in a track of the coupler that provides and maintains arm-to-arm angular accuracy for scales coupled in a fixed angle, co-planar joint, and measurement accuracy of scale markings across the joint. The track includes a lower surface; two laterally opposed parallel edge walls extending up from the lower surface and spaced apart by a dimension suitable for slidingly engaging a ruler arm width; holding tabs that extend laterally inward from both edge walls spaced above the lower surface by a dimension suitable for slidingly engaging a ruler arm thickness; an open end; and preferably a longitudinally distal registration stop. Two coupler tracks are joined with co-planar lower surfaces; and an edge wall of each joined at a fixed angle vertex. | 04-07-2011 |

| 20090139104 | MULTI-PIECE FRAMING SQUARE - In some embodiments, a multi-piece frame square may include one or more of the following features: (a) a first arm, (b) a second arm, (c) a lever capable of being received by a slot within the second arm, (d) a retention portion releasably coupled to receiver slots on the first arm and receiver slots on the lever, (e) a receiver notch at a proximal end of the first arm, (f) catch portions on the second arm for receiving the lever, and (g) receiver holes on the first arm to receive alignment pins located on the second arm. | 06-04-2009 |
| 20120266471 | Square and Ruler - A combination ruler and square has first and second elongated straight ruler members with first and second recesses in the upper surface near opposite ends of the first ruler member that receive a tongue extending from an end of the second ruler member to form first and second configurations of the combination that respectively create a square and an elongated ruler. Magnets and detents in the tongue and recesses retain the tongue in a respective recess in the first and second configurations and an extra pair of alignable magnets in the first and second ruler members cause the rule members to be attracted to each other in an aligned storage configuration of the combination where the second ruler member overlays the first ruler member. | 10-25-2012 |
| 033479000 | T-square | 3 |
| 20090119939 | T-SQUARE WITH FINGER GUARD - A finger guard for use with a T-square having a head and a blade includes an elongated body, two finger-shielding surfaces extending along a longitudinal axis of said body for accommodating an installer's thumb, a lower edge on the body that is attachable to the blade of the T-square, and a peak edge opposite the lower edge and separating upper ends of the surfaces. | 05-14-2009 |
| 20130160314 | T-plotter: tool for plotting celestial lines of position - The T-plotter is a T-shaped transparent plotting utensil consisting of two mutually perpendicular arms and equipped with a rotatable compass rose mounted on a shuttle sliding along its arm of symmetry. This device allows a simplified plotting of celestial lines of position according to the intercept method of Marcq St. Hilaire. The compass rose is used to dial in the required azimuth. The intercept distance is marked by sliding the shuttle to the appropriate distance from the top of the main body based on the latitude scale of the employed nautical chart. | 06-27-2013 |
| 20150047214 | T-SQUARE - A T-square for measuring and marking a panel comprises a housing; a rule mounted to the housing and arranged to engage a flat surface of a panel; a blade guide for receiving a blade, the blade guide mounted on the rule; and two moveable arms coupled to the housing and arranged to engage an edge of the panel. | 02-19-2015 |
| 033480000 | Try square | 2 |
| 20100281703 | Try square - A try square with a blade extending perpendicularly from the stock and a pivotal tab housed at the end of the stock opposite the blade, the purpose of the tab being to lie within the stock when the square is put against surfaces to check if they lie at 90° and to project from the stock and lie coplanar with the blade during scribing. The projecting tab supports the stock during this operation. | 11-11-2010 |
| 20130111772 | Squaring Tool with Offset Blades - A framing tool, namely framing square, is provided with an offset at the proximal ends of the two blades, so that the blades lie in parallel planes. This tool facilitates measuring and marking tubular beams, i.e., beams of generally square or rectangular cross section, but which may have rounded or radiused edges. | 05-09-2013 |
