Abstract: A square device for use by steel fabricators including a blade member and a beam member attached adjacent one end of the blade member whereby the adjacent inner surfaces of the blade member and beam member are at right angles to each other, and an elongated notch defined by the inner surface of the beam member extending from one end of the inner surface of the beam member to the other end of the beam member and which is of sufficient width whereby a portion of the notch extends above and below the blade member. In a preferred embodiment, the inner corner of the beam member is provided with a vertical groove.

Abstract: A carpenter's square is disclosed which is capable of simplifying common woodworking layouts by means of various ports and a reference point used to appropriately orientate the square. The square can also advantageously be used as a dividing tool for longitudinally dividing a piece of wood.

Abstract: A receptacle (74) in the shoe (12) of a circular saw (14) holds an accessory tool (10) which combines the functions of blade wrench and square. The base (18) of the L-shaped tool (10) is bent to provide an offset bearing surface (52) to facilitate its use as a square. The base (18) also includes a hexagonal wrench opening (46) sized to fit the saw blade retaining nut (48). An interrupted longitudinal groove (26) in the "upright" portion (16) of the L helps guide the tool (10) into the receptacle (74) and hold it there.

Abstract: An attachment for a framer's square which permits the framer's square to be self supporting on a flat, horizontal surface. The attachment has an elongated support bar with two clips which may be inserted over a blade of a framer's square. This attachment, when inserted on the inner edge of the framer's square, facilitates the scribing of a right-angle line to a rounded edge and when placed on an outer edge, permits the square to be free standing.

Abstract: A guide for guiding wallpaper knife includes a planar member with a right-angled lip formed at a forward end portion of the planar member. The right-angled lip and the planar member form a press for pushing an overlapping sheet of wallpaper into a corner, while a flat linear edge of the right-angled lip provides a guide surface for guiding the wallpaper knife along a linear path substantially parallel to the corner of a room.

Abstract: A measuring rule employs a casing which permits marking of lines perpendicular to an edge of the workpiece, as well as serving to enable measuring and marking of lines at each of a range of angles thereto.

Abstract: This marking template is preferably made from die-cut uncorrugated cardboard with slots and holes adapted to position a marking tool to define the positions of cuts and holes to be made in a piece of material. Provision is made for cuts to be made at compound angles by forming the slots to intersect a fold line in the template, or extend on opposite sides of it, the slots forming an angle other than perpendicular to the fold line at one or both sides of the fold line. The slot portions for each cut are coplanar. The portions at opposite sides of the slot thus form the traces of a cutting plane disposed at an angle to either of the faces of the template. The template is adapted to be provided in a plurality of sections with respect to length through the use of interengageable slots and tabs, or by nails engaging aligned holes, that assure longitudinal and transverse alignment of the template sections.

Abstract: A fixture for holding workpieces at predetermined angles while they are being interconnected includes a pair of legs and a hypotenuse forming a right triangle, whose three vertices are truncated to enable the fixture to function as a jig, as a template, or as a bending tool. Workpieces may easily be attached to the fixture, obviating the need for special clamps.

Abstract: A floor square for use in squaring and marking a ledger notch in the end of a floor joist and for use in marking the intended position of a ledger on a girder.

Abstract: The disclosed guide has an elongated planar body and a planar cross bar, angled normal to the body off one end edge thereof, somewhat in the configuration of a "T". One end of the cross bar projects away from the elongated body only a short distance, 1/4 to 5/8 of an inch; while the other end of the cross bar projects 11/8 to 11/4 of an inch away from the elongated body, corresponding to the width of the narrow side of a standard "metal stud" framing member. With the elongated body positioned against the wide side of the stud and the extended cross bar end squared against one narrow side of the stud, someone can consecutively mark both stud sides with this single guide setting; requiring the guide to be repositioned only once to mark the remaining narrow stud side.

Abstract: A carpenter's template useful particularly for residential framing construction has an L-shaped crosssection formed by a faceplate having a width of about 4" and a flange having a width of about 15/8". The faceplate has three series of slots for marking rafter cuts for common rafters, hip and valley rafters, and jack rafters, respectively. The flange is configured at its ends into angled edges useful for cheek cuts and dub cuts. The faceplate is marked with indicia related to roof pitch to permit the carpenter to select the appropriate slots.

Abstract: What is disclosed are novel tools for facilitating the laying of roof shingles so that shingles can be aligned on a roof to give regular and even courses. The tools provide an alignment and spacing of the shingles without the need of utilizing gauges or tools that require adjustments, and the lightweightness and small size of the tools provide easy storage at the worksite on the roof so that the workman need not make repeated trips to the ground to recover tools not having the advantages herein for storage, that have been dropped or dislodged.

Abstract: A combination device including a layout tool having a rectangular plate and a rectangular endpiece; and a square adaptor having an attachment plate and a ruler assembly. The layout tool is provided with a number of slots and apertures which allow a construction worker to make quick, standard measurements. The square adaptor includes a pivotable ruler which can be aligned parallel to or perpendicular to the longitudinal edges of the layout tool.

Abstract: A tool guide for directing hand tools over a workpiece at an angle perpendicular to one edge of the workpiece is disclosed. The guide has two perpendicular legs equipped with flanges for aligning the guide and directing a hand tool along the guide. Measuring units are provided along surfaces of the guide to allow it to be used alternately as a carpenter's square and to facilitate carpentry operations without premeasuring. The flanges are shorter than the legs to provide cutouts for clamp removal and a cross brace enables the guide to be optionally stabilized without clamps.

Abstract: A sharpening guide for dental curets. A base member is provided having thereon a positioning point, sighting sections and stone guide lines. A dental curet is aligned with the guide and a sharpening stone applied thereto to correctly sharpen the blade of the instrument.

Abstract: The invention relates to rotating saw blade adjustment devices in general, and more specifically to a very simple apparatus, comprising two metal brackets, which when used in conjunction with an adjustable triangle and/or framing square, can provide precision adjustments for either a radial arm saw or a table saw.

Abstract: This invention relates to a lay out square which can be folded from a flat position for storage to a position wherein the legs are substantially perpendicular to each other. A body comprising first and second legs spaced apart equal distances form a U-shaped member which is joined to a face marking portion formed by third and fourth legs aligned where first and second legs and having hinge means to pivotally secure the body portion to the body at substantially right angles.

Abstract: A layout tool is movable along a structural beam or girder and includes measuring scales adapted to facilitate accurate location of holes to be formed at selected places on the beam. The tool is adapted for manual use at the construction site.
