Abstract: A string line box tool comprising a chalk line box and a line block integral therewith used for guiding a string line rewardly from the chalk line box through a groove in the line block in order to provide a free holding string line for carpentry or construction work. To effect this condition the hook shaped protrusion of the line block will hook onto one end of a work project while the L-shaped metal tab on the free end of the string line will hook onto the opposite end of the work project, the string line being under tension during this condition.

Abstract: A multi-purpose, positioning and fastening strap is disclosed for use in the construction of building structures. The strap is made from a flexible, durable, non-stretchable material and has a high breaking load. The strap is usable for various construction applications, such as, the fastening or holding down of tar or felt paper on a roof, the laying down of shingles on a roof, the erection of a trussing structure for a roof, the construction of a floor, etc. The durability and breaking load of the multi-purpose strap are critical physical characteristics which are necessary for its use in the aforementioned various construction applications.

Abstract: A clip for supporting, fixing or stabilizing air hoses, water hoses, electrical cords, safety ropes, cables, etc., on an unshingled pitched roof. The clip is U-shaped and made from a strip or ribbon of material. The clip has a pair of spaced reentrant arms extending from the base. A pair of aligned spaced apertures is provided in the clip to permit a nail to pass therethrough and be partially hammered into the roof in order to secure the clip thereto; the pair of apertures is offset from the center of the clip.

Abstract: A retaining adapter for a mechanical measuring tape device extends the versatility of the tape device for construction workers. The retaining adapter can be removable or fixed to the housing of the mechanical measuring tape device. The retaining adapter has a drag hook and a drop hook, either of which can be attached to the object or construction piece to be measured. The use of the retaining adapter permits the construction worker to use the conventional measuring tape device beyond his or her natural reach.

Abstract: A clip bar for supporting, fixing or stabilizing air hoses, water hoses, electrical cords, safety ropes, cables, etc. on a shingled or unshingled, pitched roof of a building or house. The clip bar has a substantially flat element with a pair of spaced, U-shaped spring clips attached thereto. One or more of the clip bars can be secured to the roof by a nail or nails and support, fix or stabilize hoses, cords, ropes and/or cables thereto, thus, preventing these elements and any attachments thereto from sliding down and off the roof as well as preventing them from interfering with workers or roofers working on the pitched or inclined roof.

Abstract: A support for holding or restraining construction or roofing articles on an inclined or pitched roof. The support prevents construction or roofing articles from sliding down or off the inclined or pitched roof of a house or building and allows the construction worker or roofer to position the articles in the immediate area where the construction worker or roofer is working. The support may also have a tray attached to a level surface of the support so that construction tools and/or materials may be located therein for ready accessibility to the construction worker or roofer.

Abstract: This invention pertains to a portable utility jack for use on an inclined roof or a flat roof. The utility jack is constructed from a mainframe which has at least one support frame which is adjustable to several positions to accommodate, for example, various roof pitches and which provides, in conjunction with a platform tray, for the level support of various construction or paint tools, materials and supplies and/or for the fixed level support of a paint tray. The utility jack is also capable of storing and transporting the various construction or paint tools, materials and supplies. The utility jack is constructed to be collapsable and portable. In one application thereof, the utility jack has a large area, non-skid, elastomeric element on one side thereof for enhanced traction and added safety for use on an inclined roof. In another application, the utility jack has four caster wheels attached thereto for use on a flat roof.

Abstract: A multipurpose cutting device for use with power drives is disclosed. Specific and different blade configurations are provided on opposite sides of an elongated bar or a disk type support for performing different cutting functions. By securing one side of the elongated bar or disk to the end of a shaft, one function can be performed. By securing the other opposite side of the elongated bar or disk to the shaft a different function can be performed. By securing or using the elongated bar or disk at an angle to the material being cut both blade configurations can be used simultaneously to perform yet another function. The blades on the one side and the blades on the other side of the elongated bar or disk may each have the blade configuration facing in one direction of rotation of one shape and the configuration facing in the other direction of another shape for different cutting characteristics when the direction of rotation is reversed.

Abstract: A sound reducing panel is provided for use in construction of barriers of varying height between sources of objectionable noise and any sensitive area adjacent thereto, such as a freeway, a highway, construction or industrial operations, motors, generators, or other noise generating activity. Each panel consists of a designated number of parallel, hollow, triangular-shaped chambers, equally spaced apart and mounted on the panels in equal spaced relation relative thereto with the triangular-shaped panels opening toward the side of the panel opposing the source of objectionable noise.
