Abstract: An apparatus for feeding a plurality of associated screws to an associated power screwdriver having a chuck. The apparatus includes a main body that includes a shaft dimensioned and configured to engage the chuck of the associated power screwdriver. The main body also includes a bit and apparatus for holding the bit and transmitting rotational energy from the shaft to the bit. The apparatus also includes a magazine dimensioned and configured to receive a plurality of associated screws disposed with the respective axes thereof in substantially coplanar relationship. The apparatus also includes apparatus for detachably connecting the magazine to the main body and a pickup assembly including a spring apparatus for gripping associated screws on opposed sides of the associated screws and apparatus for pivoting the spring apparatus between a first position proximate to the magazine and a second position proximate to the bit.

Abstract: A wall board lifting and positioning apparatus which includes an elongated boom having first and second ends and apparatus for holding an associated individual panel. The apparatus for holding is carried on the elongated boom proximate to the first end thereof and apparatus for moving the boom through a plurality of substantially coplanar positions. The apparatus includes apparatus for pivoting and rotating the apparatus for holding to position the apparatus for holding. In some forms of the invention the apparatus for moving includes a first elongated control link and a second elongated control link. The boom may be supported on a head member. The first control link and the second control link may be each pivotally connected to the head member and may also be pivotally connected to the boom.

Abstract: A portable folding crane which includes an elongated base member having first and second axial extremities and first and second elongated telescoping legs. Each of the legs has first and second axial extremities and each of the first axial extremities is pivotally connected proximate to respective axial extremities of the base member. A telescoping column member has first and second axial extremities and the first axial extremity of the telescoping column member is pivotally connected to the base member. A boom member has first and second axial extremities and the second axially extremity of the telescoping column member being the first axial extremity of the boom member are pivotally connected. Apparatus for urging the boom member to pivot with respect to the column member is also provided.
