Patent number: 4796737Abstract: A clutch and lock mechanism adapted for use with a double shuttle table utilizing two individual drive shafts wherein a first shaft ring assembly is fixedly coupled to a first shaft and a second shaft ring assembly is coupled to the second shaft. The first and second shafts and shaft ring assemblies are spaced from one another along the common axis of rotation of the first and second shafts and an engaging mechanism is positioned between the two shaft ring assemblies and movable therebetween. When the engaging mechanism, at least a portion of which is rotationally locked to the second shaft, is moved to a first position, it is rotationally locked to the first shaft and rotation of the first shaft thereby results in the rotation of the second shaft. When the engaging mechanism is moved to a second position, opposed to the first position, it is disengaged from the first shaft and prevents the rotation of the second shaft.Type: GrantFiled: March 13, 1987Date of Patent: January 10, 1989Assignee: Litton Industrial Automation Systems, Inc.Inventor: D.

Patent number: 4345524Abstract: A structure for a load carrying vehicle and the track therefor. The load carrying vehicle includes a load carrying platform and a pair of side plates, one plate located adjacent to each of the platform sides. The side plates are structurally weakened, that is, the rigidity of the side plates is controlled by, for example, fabricating them to include grooves, apertures, etc., so that the vehicle may deflect longitudinally. This is done so that all the wheels of the vehicle will be in contact with the track, and thereby serve to support at least part of the load being carried, thus improving the weight distribution of the vehicle load on the wheels and on the track. The track provided for supporting the load carrying vehicle, which track may be fabricated by roll forming a sheet of steel, includes four sections, two of which sections join the other two at an obtuse angle thereby providing a pivot point or flexure.Type: GrantFiled: February 26, 1980Date of Patent: August 24, 1982Assignee: Litton Systems, Inc.Inventor: Weston R.
