Abstract: A chest mounted book holder for carrying a field guide or other reading matter while hiking or observing nature attached to the chest area of an outer garment or to an adjustable upper body harness. The book holder includes page holders for holding the book open at a desired page and protects the pages from turning in the wind and is equipped with side stops so the book cannot fall out. Adjusting straps allow the book to be positioned at a comfortable distance and angle from the reader and can be folded and secured against the chest when not in use. The user is able to turn the pages of a book when the book holder is in an open position and to make notes on the book or adjacent to it.

Abstract: A non power tool for facilitating the unassisted installation of heavy doors. The tool consists of a lever assembly (FIG. 1) and a rotatable fulcrum assembly (FIG. 2). The door mounting platform (18) end of lever (10) is placed under the approximate center of the door and by applying foot pressure to the foot rest (19) or opposite end of the lever a heavy door may be lifted off the ground to the exact height necessary to engage the door fasteners while being balanced vertically by one hand of the installer. By applying side pressure to the lever (10) while maintaining lift pressure, the door may be swung into the opening by rotating the fulcrum assembly (FIG. 2) around a turntable bearing (14) intermeshing the two parts of the hinge and allowing the installer to set the hinge pins in place with his free hand. A soft cushioning material (15) separates the tool from what may be a finished floor surface thereby eliminating the possibility of damage to the floor.

Abstract: A solar heating panel utilizing an improved panel member construction to increase the strength and heat transfer capacity of the panel. The panel has upper and lower layers of individual interconnected panel members, with the panel members in the upper layer including a pair of spaced outwardly extending leg portions and a bight portion therebetween having a plurality of spaced longitudinal fins formed therein extending downwardly into the panel members of the lower layer. A sheet of transparent material overlies the upper layer of panel members. Air flowing in the channels of the lower layer of panel members absorbs heat collected from the sun in the upper layer of panel members, with the fins aiding in transferring heat from the panel members in the upper layer to the panel members in the lower layer, while rigidifying the entire panel structure.
