| 20120174421 | STRAIGHT EDGE CLAMPING DEVICE HAVING CONNECTION LOCK - A straight edge clamping device includes front and rear sections and first and second connection locks. The connection lock is configured to be fit into the connecting ends of the elongated hollow portions of the front and rear sections. The first and second connection locks fit into the connecting ends of the first and second elongated hollow portions of the front and rear sections so as to connect and lock the front section with the rear section securely. Each of the first and second connection locks comprises: an outer surface fitting substantially tightly to at least a part of inner surface of the elongated hollow portion and an inner groove recessed inward from the outer surface, so as to provide rigidity against bending, shearing, or straining force on the straight edge clamping device. | 07-12-2012 |
| 20130160313 | OFFSET MEASURER - A measurement apparatus for measuring levels and plumb of items with offset dimensions comprises a base, a cross member, and a slide bracket. The cross member may have a shaft and a slide. The shaft may be rotatable around the base. The slide may move along on the shaft. The slide bracket may be connected to the base and the shaft. The cross member and the slide bracket may be slidable inside the slot of the base. | 06-27-2013 |
| 20150298299 | STRAIGHT EDGE BAR CLAMP - A straight edge bar clamp comprises an elongated channeled bar, a threaded base, first and second movable jaw bodies, bosses or divots, a catching device, and a threaded shaft. The elongated channeled bar having an inner channel portion. The threaded base is installed fixedly in the elongated channeled bar. The first movable jaw body is installed movably and partially in the elongated channeled bar between the second movable jaw body and the end of the bar furthest from the threaded base. The bosses or divots are provided on an inner surface of the inner channel portion and configured to define the predetermined stopping positions of the first movable jaw body. The catching device is provided in the first movable jaw body. The second movable jaw body is installed partially in the elongated channeled base movably between the threaded base and the first movable jaw body along the elongated channeled bar. | 10-22-2015 |
| 033431000 | Navigation | 1 |
| 20120110865 | CHART SPECIFIC NAVIGATION PLOTTER AND METHOD FOR INEXPENSIVE PRODUCTION THEREOF - A navigational plotter for use with a selected navigational chart and its method for production include providing a generally transparent elongated planar straight edge member having each of a first and a second straight edges parallelly disposed opposite one another bounding a generally rectangular interior surface. A printed central axis bisecting the rectangular interior surface and at least one compass rose arranged to have its North/South ordinal points to lie upon the printed central axis thus to allow the user to maintain orientation of the plotter on the chart. A first distance scale is calibrated in accord with the scale of the selected chart along a selected line of latitude. The first distance scale is printed to span the East/West ordinal points on the compass rose and along the first straight edge. A second distance scale is calibrated in accord with longitude according to a Mercator projection. | 05-10-2012 |
| 033436000 | Linear counter rule | 1 |
| 20090188122 | MEASURING APPARATUS - A scale base is fixed to a base in a plurality of locations which are aligned in a measuring direction (a Y direction) in which measurement by a scale is carried out, slits are provided in the scale base in positions lying between the locations where the scale base is fixed to the base, the scale is supported by the scale base in two or more of the locations where the scale base is fixed to the base, and the scale base has gaps between the base and the scale base in positions other than the locations where the scale base is fixed to the base and between the scale and the scale base in the positions other than the locations where the scale base is fixed to the base. | 07-30-2009 |

| 20130067757 | Straightedge Guide - The present invention is a straightedge guide which is to accommodate a carpenter in performing accurate linear cuts. The present invention has a straightedge and a carriage, which rides along the rails of the straightedge. During operation, a cutting tool such as a circular saw is attached to plate of the carriage. Subsequently, the carriage and the attached circular saw are transported along the rails of the straightedge while the circular saw is cutting through the material beneath both the circular saw and the straightedge. The present invention is also useful in performing vertical straight cuts as the present invention has a vertical holder, which helps stabilize the straightedge upon a vertical flat surface. Attached to each rail of the straightedge is a ruler, which provides accurate measurements in woodcutting. Along with straight cuts, the present invention is also useful in performing circular cuts as the present invention is rotatable. | 03-21-2013 |
| 20130152415 | MEASURING DEVICE - A measuring device includes a bracket, a sliding ruler, a securing assembly, and a driving assembly. The bracket includes a first set of scale lines. The sliding ruler is slidably attached to the bracket and includes a second set of scale lines. The securing assembly includes a securing member and a resilient member mounted to the securing member. The driving assembly is rotatably attached to the bracket and includes a handle and a gear secured to the handle. The gear is rotatable to slide the sliding ruler relative to the bracket; the securing member is secured to the bracket, and the resilient member is secured between the sliding ruler and the bracket, to prevent the sliding ruler from sliding relative to the bracket. | 06-20-2013 |
