Patent number: 4841852Abstract: A mobile apparatus having utility in the construction of roof trusses at a job site. An elongate trailer frame is mounted to a wheel and axle assembly and is transportable on public highways by towing. A jig assembly supported by the frame is formed primary of uni-strut members and has a first elongate fixed position side rail and a second parallel but movable jig support rail. Plural transversely disposed jig members are slidably mounted for lateral movement along the extent of the first and second side rails of the jig assembly. A clinching device is mounted for longitudinal movement along the extent of the jig assembly by an overhead cantilevered track support structure. The jig assembly is longitudinally extendable, and the overhead track support member has a hingedly mounted auxiliary portion that may be deployed so that the clincher device can reach even the extended portion of the jig assembly.Type: GrantFiled: March 17, 1988Date of Patent: June 27, 1989Inventors: Jim Kubiak, S. R. Bliven

Patent number: 4771697Abstract: A load carrier for the carrier track of a power and free conveyor has load carrying structure comprising a front suspension member pivotally connected to a front trolley and a rear suspension member pivotally connected to a rear trolley, each suspension member having an upper portion extending transversely to one side of the track and a vertical portion extending obliquely downwardly from the upper portion through a vertical plane containing the pivotal connections. A load supporting member connects the lower ends of the suspension members and is positioned so that the center of gravity of the load carrying structure and of a load supported thereby lies in the vertical plane. A drip pan is mountable below the upper portions of the suspension members.Type: GrantFiled: September 25, 1986Date of Patent: September 20, 1988Assignee: Jervis B. Webb CompanyInventor: Clarence A.

Patent number: 4770106Abstract: The rail vehicle has four wheels, the two on one side are pivotably mounted on bogies which are themselves pivotably mounted to the frame on the vehicle. The wheels on the other side just pivot on vertical axes.Type: GrantFiled: January 8, 1987Date of Patent: September 13, 1988Assignee: Mannesmann AGInventor: Adolf Rose

Patent number: 4671186Abstract: An automatic, rail-based passenger and cargo transportation system which is particularly well suited for use as a moderate speed people mover is disclosed. The system includes a rail structure on which passive carrier cars are movably supported from opposite sides of the rail. In one aspect a plurality of drive wheels are rotatably mounted to the rail assembly and span across the width of the rail structure so as to drive the carrier cars along the rail in opposite directions on opposite sides of the rail. In another aspect of the invention, the carrier cars are cantilever supported from the sides of the rail so as to cause gravity biasing of the cars inwardly such that a shoe is forced into driving engagement with alternating toothed and smooth drive wheels mounted in the rail framework and sufficiently spaced so that only one toothed drive wheel interengages with the shoe assembly at any time.Type: GrantFiled: June 4, 1985Date of Patent: June 9, 1987Inventor: Jan K. Kunczynski

Patent number: 4664590Abstract: The transportable robot system comprising a plurality of robot working areas, an unmanned transporter for transporting a robot mounted thereon and moving between the robot working areas and a travel track for the unmanned transporter to provide a communication between the areas. The unmanned transporter provides a base to which to robot is mounted and secured, and a locating station for the base is provided near a machine tool in the working area so that the base may be put on the locating station at a predetermined position.Type: GrantFiled: May 10, 1985Date of Patent: May 12, 1987Assignee: Murata Kikai Kabushiki KaishaInventor: Hiroshi Maekawa

Patent number: 4648777Abstract: A conveyor system comprises a runway rail in the form of an extruded hollow body of oblong cross-section. The runway rail has a top portion which includes a pair of parallel surfaces including between them an angle. A similar pair of parallel surfaces is disposed at the bottom portion of the runway rail, which surfaces are parallel to respective surfaces of the top portion and include the same angle. A crab having load and guide wheels is disposed on the runway rail, the load wheels engaging the pair of surfaces at the top portion and at least one guide wheel engaging one of the surfaces at the bottom portion. A driving motor mounted to the lateral flange of the crab is adapted to drive the crab along the runway rail by engaging a stationary drive element mounted to a side rail of the runway rail. A hoist mounted to the crab serves to raise and lower work pieces.Type: GrantFiled: February 25, 1985Date of Patent: March 10, 1987Assignee: Branson Ultrasonics CorporationInventor: Karl-Friedrich Eichenauer

Patent number: 4584944Abstract: A conveyor system in which loads supported by forwardly driven carriers of an overhead power and free conveyor are automatically transferred to a second conveyor arranged below the overhead conveyor at a transfer zone and driven at the same forward speed. The vertical spacing between the overhead and second conveyors is decreased from a greater spacing at which a load is engaged and supported by downwardly extending structure of a carrier to a lesser spacing at which the load is disengaged from the carrier structure and is supported by the second conveyor. As the disengaged carrier and load move forwardly in unison on their respective overhead and second conveyors, the carrier is engaged and moved by a transfer conveyor obliquely to the second conveyor at an increased speed such that the carrier continues to move forwardly in unison with the load while simultaneously moving laterally out of alignment therewith.Type: GrantFiled: April 25, 1984Date of Patent: April 29, 1986Assignee: Jervis B. Webb CompanyInventor: Clarence A. Dehne

Patent number: 4579062Abstract: An automatic latching assembly is provided for retaining vehicle bodies upon conveyor carriers during conveyance into and out of treatment baths. The assembly includes a carrier having latches mounted thereon which selectively engage the vehicle body securing it to the carrier. The latches comprise pivoting hooks rotatably mounted upon the carrier. Generally, gravity actuates pivoting of the hooks, biasing them into latching orientations. Unlatching orientations are achieved by a stationary, upward biasing cam operating upon the hooks. A downward biasing cam aids in the gravity actutation of the hooks into the latching orientation. The assembly selectively, automatically secures the vehicle body to the conveyor carrier, or releases it therefrom, as desired during transport of the vehicle body by the conveyor.Type: GrantFiled: December 24, 1984Date of Patent: April 1, 1986Assignee: Mid-West Conveyor Company, Inc.Inventors: Robert B. Clark, Erik M. Andersen
