Abstract
Abstract A machine for use in placing of a wall or ceiling panel in position which holds the panel firmly in place as it is nailed into the structure of a building. The machine is mounted on wheeled base and fitted with a support platform mounted by compression springs to fixed arms. The fixed arms are oriented perpendicular to the plane of the support platform, and are pivotably mounted to an extendable arm linkage joined to the base. The extendable arm linkage consists of a plurality of pivotable arms, rotatably linked by a first set of chain drives driven by a first gear motor for rotation of the arms of the linkage to extend or withdraw the platform in relation to the base, and a second set of chain drives driven by a second gear motor which serves to rotate the plane of the support platform with respect to the base plane.

Claim 1
Independent Claim
297 words
Apparatus for supporting a building panel in place against a horizontal ceiling or vertical wall support comprising, a base unit jointed to, a pivotable linkage of support members joined to a platform, said support members comprising three pairs of spaced parallel arm members, with said base unit pivotably mounted to a first pair of said parallel arm members, at the lower extremity of each said arm member, said platform mounted in non-rotatable engagement to a second pair of said parallel arm members at the upper extremity of each of said arm members, with a third pair of said arm members pivotably linking the said first pair of arm members to the said second pair of arm members, in which the upper extremity of each of the first pair of arm members is pivotably linked to the lower extremity of each of the third pair of arm members, and the upper extremity of each of the third pair of arm members is pivotably linked to the lower extremity of the second pair of arm members, with a first motorized means mounted in the base unit, said first motorized means joined to first drive means for simultaneously rotating the first pair of arm members with respect to both the said base unit and with respect to the said pair of third arm members, and a second motorized means mounted in the base unit, said second motorized means joined to second drive means for rotating the said second pair of arm member with respect to the said third pair of arm members, such that said second motor means may rotate the platform, attached to the said second pair of arm members, with respect to the base unit, independently of the positions of the first and third pair of arm members.

Apparatus for supporting a building panel in place against a horizontal ceiling or vertical wall support comprising, a base unit jointed to, a pivotable linkage of support members joined to a platform, said support members comprising three pairs of spaced parallel arm members, with said base unit pivotably mounted to a first pair of said parallel arm members, at the lower extremity of each said arm member, said platform mounted in non-rotatable engagement to a second pair of said parallel arm members at the upper extremity of each of said arm members, with a third pair of said arm members pivotably linking the said first pair of arm members to the said second pair of arm members, in which the upper extremity of each of the first pair of arm members is pivotably linked to the lower extremity of each of the third pair of arm members, and the upper extremity of each of the third pair of arm members is pivotably linked to the lower extremity of the second pair of arm members, with a first motorized means mounted in the base unit, said first motorized means joined to first drive means for simultaneously rotating the first pair of arm members with respect to both the said base unit and with respect to the said pair of third arm members, and a second motorized means mounted in the base unit, said second motorized means joined to second drive means for rotating the said second pair of arm member with respect to the said third pair of arm members, such that said second motor means may rotate the platform, attached to the said second pair of arm members, with respect to the base unit, independently of the positions of the first and third pair of arm members.
Claim 3
Dependent Claim
268 words
The combination as recited in claim 1 in which each of the arm members of the first pair of arm members is of hollow construction, with each of the said arm members enclosing a chain drive, and with a first chain drive in one of the arm members linked to the first motorized means in the base unit and with a second chain drive in the other of the arm members linked to the second motorized means in the base unit, with each of the arm members of the third pair of arm members being of hollow construction, with each of the said arm members enclosing a chain drive, and with a first chain drive in one of the arm members linked to the first chain drive of the first pair of arm members, and with the second chain drive in the other of said arm members linked to the second chain drive of the first pair of arm members, with one of the arm members of the second pair of arm members being of hollow construction and enclosing a chain drive linked to the second chain drive of the third pair of arm members, with said first chain drives mounted to first means to rotate the linkage of the first pair of arm members to the base unit and to second means to rotate the linkage of the first pair of arm members to the third pair of arm members, with said second chain drives mounted to third means to rotate the linkage of the second pair of arm members to the third pair of arm members.
Claim 4
Dependent Claim
27 words
The combination as recited in claim 1, in which the arm members may be rotated so as to fold within the base unit, in the retracted position.
Claim 5
Dependent Claim
60 words
The combination as recited in claim 1 in which the platform is fitted on a first end with a rotatable bar which in a first position may be manually rotated to project above the surface of the platform and in a second position manually rotated to lie flush with or below the surface of the platform about the platform end.
Claim 6
Dependent Claim
67 words
The combination as recited in claim 4 in which the platform is fitted on a second end with a rotatable bar which, in the first position, may be manually rotated to project above the surface of the platform and to clamp a sheet of material to the platform, and rotated to a second position, flush with or below the surface of the platform, about the platform end.
Claim 7
Dependent Claim
27 words
The combination as recited in claim 1 in which the platform is mounted to each of the second parallel pair of arm members by compression spring means.
