Abstract: An adjustable square assembly has a framing square with orthogonal limbs, slide fittings for mounting on the respective limbs with an adjustable angle blade therebetween and a tri-square blade and body for adjustable mounting on one of the limbs so that the tri-square blade is in parallel with the other limb of the framing square. One limb of the framing square has a single groove which cooperates with one of the slide carriers as a means whereby the carrier can be adjustably clamped in place through a locking screw on the carrier. The other limb is wider and has a pair of grooves so that the other limb can take the slide carrier in one of the grooves and the framing square body in the other groove. All the parts are reversible so that the slide carriers can be mounted on either limb of the framing square and can operate either along the inner and outer edges of the respective limbs.

Abstract: A pipe fitter's tape measuring strip of 25 foot length is marked on one surface thereof with cumulative inch markings along one edge, with information providing take-off charts along the other edge at a leading end of the strip and with cumulative foot and inch markings following the charts along the remainder of the strip length. The opposite surface of the strip is marked with charts providing information of flange sizes related to different pipe sizes.

Abstract: A switch device for swatting insects or for use as a brush and the like has a tubular handle, a switch in the handle formed from nylon strands which are folded double about a fold line, a cord having one end tied around the fold line to secure the switch and another end secured to the inner end of the handle. The switch can be fully retracted into the handle for storage or it can be pulled from the handle by different amounts to suit its different modes of use. The switch is retained in the handle by friction.

Abstract: Travel of a printing head between ink-receiving and marking positions is guided along an arcuate path by a fluid power piston device having a cylinder pivotally mounted at its forward end on the frame of the printing apparatus. The longitudinal axis of the ink storing cartridge engaged by the printing head in the ink-receiving positions, is inclined downwardly and is tangent to the travel path at the adjacent terminal end thereof.
