Abstract
Abstract A mechanical shaker mechanism used in the laboratory for imparting oscillry motions to a military tank turret. The mechanism can be programmed to duplicate test track conditions at lesser cost then would be required to operate a complete tank on a proving ground. The mechanism is designed to include special link mechanisms between the power devices and the turret-support ring. Other stabilizer link mechanisms are provided between the turret-support ring and stationary anchorage points.

Claims Analysis
Total Claims: 11
Claim 1
Independent Claim
234 words
A tank turret shaker mechanism comprising an annular platform sized to receive a turret; said platform having an opening therein to accommodate a circular basket depending from the turret; said platform occupying a horizontal plane when the turret has a level attitude; a first anchorage structure spaced laterally from said platform; a second anchorage structure spaced laterally from said platform; said platform and anchorage structures occupying a common horizontal plane when the turret has a level attitude; a first elongated stabilizer link extending from the platform to the first anchorage structure; a second elongated stabilizer link extending from the platform to the second anchorage structure; said stabilizer links being oriented at right angles to each other in a common horizontal plane when the turret has a level attitude; said first stabilizer link being located on an imaginary line representing the longitudinal axis of the tank designed to receive the turret; said second-stabilizer link being located on an imaginary line representing a pitch axis for the tank; three platform support structures spaced equidistantly around the platform; one of said platform support structures being located on the aforementioned longitudinal tank axis; each platform support structure comprising an upright fluid cylinder means located substantially directly below a section of the platform, and a support link extending upwardly from the fluid cylinder to the platform; each support link being oriented vertically when the turret has a level attitude.
Claim 2
Dependent Claim
234 words
A tank turret shaker mechanism comprising an annular platform sized to receive a turret; said platform having an opening therein to accommodate a circular basket depending from the turret; said platform occupying a horizontal plane when the turret has a level attitude; a first anchorage structure spaced laterally from said platform; a second anchorage structure spaced laterally from said platform; said platform and anchorage structures occupying a common horizontal plane when the turret has a level attitude; a first elongated stabilizer link extending from the platform to the first anchorage structure; a second elongated stabilizer link extending from the platform to the second anchorage structure; said stabilizer links being oriented at right angles to each other in a common horizontal plane when the turret has a level attitude; said first stabilizer link being located on an imaginary line representing the longitudinal axis of the tank designed to receive the turret; said second-stabilizer link being located on an imaginary line representing a pitch axis for the tank; three platform support structures spaced equidistantly around the platform; one of said platform support structures being located on the aforementioned longitudinal tank axis; each platform support structure comprising an upright fluid cylinder means located substantially directly below a section of the platform, and a support link extending upwardly from the fluid cylinder to the platform; each support link being oriented vertically when the turret has a level attitude.
Claim 3
Dependent Claim
31 words
The tank turret shaker mechanism of claim 1, each support link having a first universal joint connection with the fluid cylinder means and a second universal joint connection with the platform.
Claim 4
Dependent Claim
53 words
The tank turret shaker mechanism of claim 2 wherein the turret basket includes a floor occupying a horizontal plane when the turret is in a level attitude; the support links having their second universal joint connections located slightly below the plane of the basket floor when the turret is in a level attitude.
Claim 5
Dependent Claim
46 words
The tank turret shaker mechanism of claim 1, said first stabilizer link having an A-frame configuration in the horizontal plan dimension, the wide end of the A-frame being located at the platform, and the narrow end of the A-frame being located at the first anchorage structure.
Claim 6
Dependent Claim
29 words
The tank turret shaker mechanism of claim 4, said first stabilizer link having a universal joint configuration with the first anchorage structure, and spaced pivotal connections with the platform.
Claim 7
Dependent Claim
32 words
The tank turret shaker mechanism of claim 1, said second stabilizer link having a first universal joint connection with the platform, and a second universal joint connection with said second anchorage structure.
Claim 8
Dependent Claim
30 words
The tank turret shaker mechanism of claim 1 wherein said first stabilizer link has a pivotal connection with the platform, and a universal joint connection with said first anchorage structure.
Claim 9
Dependent Claim
34 words
The tank turret shaker mechanism of claim 1, said one platform support structure being connected to the platform at a point thereon diammetrically opposed to the platform connection point for the first stabilizer link.
Claim 10
Dependent Claim
27 words
The tank turret shaker mechanism of claim 1, each stabilizer link having a length that is approximately the same as the outside diameter of the annular platform.
Claim 11
Dependent Claim
64 words
The tank turret shaker mechanism of claim 1, said annular platform comprising a flat upper plate normally occupying a horizontal plane, a flat lower plate normally occupying a horizontal plane, and a connector plate joining the upper and lower plates; said connector plate having an arcuate annular configuration in horizontal plan, and a vertical configuration in radial planes generated from the platform central axis.
