Abstract
Abstract In an environment wherein a pair of basic structures are interrelated for limited relative movement and wherein one structure carries a controllable part and the other carries a controlling part, the linkage and mounting means between and for the parts includes provision compensating for such relative movement in such manner that the control mechanism is not affected by such relative movement.

Claims Analysis
Total Claims: 9
Claim 1
Independent Claim
151 words
In combination: a first structure, a controllable member carried by said first structure for back-and-forth movement along a defined path, a second structure associated with the first structure for limited relative movement, a control shaft spaced from the controllable member and disposed crosswise of the aforesaid path, an arm fixed to the shaft, a first support mounted on the first structure and extending to the shaft adjacent to the arm, a second support fixed to the second structure and extending to the shaft relatively axially remote from the arm, a first self-aligning bearing journaling the shaft on the first support adjacent to the arm, a second self-aligning bearing journaling the shaft on the second support relatively axially remote from the arm, and link means eXtending between and connected at opposite ends respectively to the arm and member for transmitting motion to move the member in response to rocking of the shaft.
Claim 2
Dependent Claim
151 words
In combination: a first structure, a controllable member carried by said first structure for back-and-forth movement along a defined path, a second structure associated with the first structure for limited relative movement, a control shaft spaced from the controllable member and disposed crosswise of the aforesaid path, an arm fixed to the shaft, a first support mounted on the first structure and extending to the shaft adjacent to the arm, a second support fixed to the second structure and extending to the shaft relatively axially remote from the arm, a first self-aligning bearing journaling the shaft on the first support adjacent to the arm, a second self-aligning bearing journaling the shaft on the second support relatively axially remote from the arm, and link means eXtending between and connected at opposite ends respectively to the arm and member for transmitting motion to move the member in response to rocking of the shaft.
Claim 3
Dependent Claim
22 words
The invention defined in claim 1 in which the first support extends generally along the line of movement of the link means.
Claim 4
Dependent Claim
55 words
The invention defined in claim 1 in which the second support includes first and second legs spaced apart axially of the shaft, one leg carries the second self-aligning bearing and the second leg has a slot through which the shaft passes, said slot being generally parallel to the line of movement of the link means.
Claim 5
Dependent Claim
35 words
The invention defined in claim 3 in which the second support is in the form of a U having a bight fixed to the second structure and including the aforesaid legs as integral parts thereof.
Claim 6
Dependent Claim
68 words
The invention defined in claim 1 in which the first support extends generally along the line of movement of the link means and the second support includes a leg part extending from the second structure to the shaft adjacent to the arm and the leg part has a slot through which the shaft passes, said slot being elongated generally along the line of movement of the link means.
Claim 7
Dependent Claim
36 words
The invention defined in claim 5 in which the first support is so mounted on the first structure as to enable axial shifting of the shaft as the second structure moves relative to the first structure.
Claim 8
Dependent Claim
34 words
The invention defined in claim 1 in which the first support is so mounted on the first structure as to accommodate axial shifting of the shaft as the structures move relative to each other.
Claim 9
Dependent Claim
17 words
The invention defined in claim 1 in which the shaft is axially slidably carried in the bearings.
