Abstract: An apparatus which is useful on pitched roofs includes structural features which help keep roofing materials from sliding off the roof. The apparatus also protects roofers from heat and abrasion from the roof surface on which they are working. A substantially solid foam rubber wedge forms one component of the apparatus, and a substantially planar pad forms the other component of the apparatus. These components are placed in proximity to each other so that the roofer, when situated on the pad, can readily reach roofing materials disposed against the wedge. The wedge resiliently compresses when roofing materials are placed on its upper surface. This resilient compression, the angle of orientation of the wedge's upper surface, and the frictional engagement of the wedge with the roof surface each contribute in varying degrees to holding roofing materials in position on the roof.

Abstract: The present invention is directed to an improved tool for use in mounting a joist hanger on a header. The tool can be made to accommodate a joist hanger of a single size or can be made so as to be adjusted in size to accommodate joist hangers of different sizes. In the latter cases, a first set of bars can separate from the adjacent, second set of bars to expand the width of the space at the side of which a number of magnets are carried. This allows for greater versatility than when the bars are stationary.
Abstract: At least one scored screw is driven into the squeak area with a specialized driving bit and an alignment and depth control fixture. The alignment and depth control fixture is used to direct the scored screw to the proper point into the floor so that the scored area is at or beneath the surface of the floor. The driving bit can stop driving the screw at the desired position. After the alignment and depth control fixture is removed, a gripping tool is used to apply force to the screw and break the screw at the prescored position. The barrel of the screw being left in the floor locks the floor or the step to the desired support. One screw or series of these screws in usually an arcuate or a radial fashion around the squeak area, can eliminate the squeak.
Abstract: Squeaks in a floor or stair are eliminated by driving screws in the area. At least one scored screw to be driven into the squeak area combines with a specialized driving bit and a alignment and depth control fixture to eliminate the squeak. The alignment and depth control fixture can be used to direct the scored screw to the proper point while the driving bit can stop driving the screw at the desired position. After the alignment and depth control fixture is removed, the screw is broken at the prescored position. To minimize damage to an in place carpet, a tape is wrapped around the threads of the screw.
Abstract: A new and improved ceiling sheet installation apparatus includes a set of four ceiling-mounted sheet material support assemblies. Each sheet material support assembly includes a ceiling mounting portion and a sheet retaining portion. The ceiling mounting portion includes a channel for receiving a fastener for attaching to a fixed object in a ceiling. The sheet retaining portion includes a sloped upper surface for receiving an edge of the sheet material and for retaining the sheet material adjacent to the ceiling by supporting the edge of the sheet material. With the sloped upper surface, the edge of the sheet material is wedged between the sloped upper surface and the ceiling. The channel is oriented in the ceiling mounting portion such that the sheet material support assembly is capable of selectively rotating around the fastener to and from two positions.
Abstract: In the thin set laying of stone or ceramic tile, tiles are set by floating them over a uniformly applied screed of adhesive applied to a level substrate. In this invention combination spacing/levelling devices are used to equally space the corners of adjacent tiles and to maintain them at an equal elevation over the adhesive and substrate. The spacer/leveller device may comprise spacing fins and a guide for maintaining the corner of adjacent tiles flush while mortar is setting. The device works as a guide to facilitate level installation with uniform grout joints and it becomes part of the permanent fabric of the installation. Tiles are temporally supported by spacer/levellers at each corner (while adhesive is drying) and by virtue of the spacer/leveller design they are automatically flush to each other with equal joint spaces separating them. The invention substantially reduces the dependence on the skill of the tile layer to space tiles equally and set them on the same horizontal plane.

The trolley travels along the beam as the beam pivots on the floor of the building from vertical to diagonal position during corresponding pivotal movement of the prefabricated wall from horizontal to vertical position.
Abstract: A tool for lap siding installation includes a current board slot, a reference board slot and a lower surface, all three of which are disposed at an angle .alpha. from a reference surface at the top of the tool. The angle .alpha. corresponds to the angle between properly installed siding boards and the wall upon which they are installed. The current board slot has dimensions conforming to the dimensions of the siding being installed. The reference board slot is shorter than the current board slot by the amount of overlap that is desired between adjacent boards after the siding is installed. Optionally, a second set of these features with alternative dimensions can be disposed on the back of the tool making it suitable for use in installing a second type of siding when its orientation is reversed. To use the tool, a current board to be installed is lifted until it is close to its desired position and then fitted within the current board slot of the tool.
Abstract: A device of novel design employed as a support and guide during the installation of horizontally-disposed building siding, said device comprising principally a shelf-like component and a means incorporating a camming action for clamping the shelf-like component onto an installed length of siding. When two or more of the devices are clamped vertically at spaced intervals onto the uppermost length of installed siding, the shelf-like components provide a horizontal base on which the siding to be installed at the next higher level can be supported during installation, thereby enabling an installer to work alone. The shelf-like components further function to correctly position the siding to be installed relative to the siding already in place without the need for constant measuring and leveling. The device operates in a quick, easy and trouble-free manner, and it assures efficient, accurate and uniform siding installation.
