Abstract: A distance-transferring device comprising a plurality of interconnected rails. Each rail, when extended, is self-supporting. Once the rails are extended and locked in place between two points, two planes, or one point and one plane, an accurate representation of a distance between the two points, two planes or one point and one plane is obtained. This distance can be transferred to another location without having to memorize a numerical measurement. Opposing abutting angled ends provide for both easy access into corners and a clear visual for when the abutting angled end contacts a plane or mark. A rotating component allows for operating the invention in more than one plane. A movable catch hooks onto an object such as wood moldings to facilitate the measurement transfer without adding any error to the distance being transferred. Extension stops prevent the rails from longitudinal separation. Bubble vials are provided for leveling both horizontally and vertically.

The second housing includes a groove corresponding to the perforation of the first housing, wherein the groove has an inner thread formed on a portion of inner wall thereof. The fastening device includes a head portion and a shaft portion, wherein the shaft portion has an external thread engaged with the inner thread of the groove and the head portion is sustained against the ring-shape member, thereby coupling the first housing with the second housing. The shielding element is inserted into the perforation of the first housing for shielding the head portion of the fastening device.

Abstract: A construction level with modular detachable sections is herein disclosed. In its detached state, the level resembles a conventional two-foot level with the typical three bubble vials indicating levelness at angles of zero degrees (0°), forty-five degrees (45°), and ninety degrees (90°). If levelness over a larger distance is required, one (1) or both detachable end portions of the level are attached using sliding joints thus allowing the device to extend to a four (4) foot length. The attaching joints allow for the extension without a loss of accuracy. Each end piece has its own bubble vial to verify levelness at any point along the device. In such a manner, the device may also be used as a one-foot torpedo level. The use of the modular construction level allows for the accuracy and precision of a long level with the convenience and usability of a shorter level.

Abstract: A compass includes two legs having upper ends interconnected in a leg joint and lower ends with holders for refills or styluses. An adjusting spindle penetrates the legs, in particular, in vicinity of the leg joint. The legs have carrier zones in the form of widenings serving in a region between the leg joint and the free leg ends as a base of an information bearing surface surpassing the width of the legs in their spreading plane.

If the compass is closed, two mounting disks of the information bearing surfaces lie congruently above one another and only two outer information bearing surfaces and can be seen. All four information bearing surfaces can be seen in the open state of the compass.
