Abstract
Abstract A governor control mechanism includes a shaft rotatably mounted in a casing, and to which is connected linkage means for controlling a governor upon rotation of the shaft. A control lever is situated outside the casing and is connected to the shaft by means which are removable, along with the control lever, to allow a sound-suppressive casing to be installed about the first-mentioned casing without removal of the shaft.

Claims Analysis
Total Claims: 7
Claim 1
Independent Claim
198 words
A mechanism for controlling an engine apparatus comprising: a first casing; shaft means rotatably supported in the first casing; means interconnecting the shaft means and engine apparatus so that the engine apparatus is responsive to movement of the shaft means; a second casing positionable about the first casing; a control lever positioned outward of the first casing; and means interconnecting the control lever with the shaft means, meanwhile allowing disconnection of the control lever from the shaft means so that, upon disconnection of the control lever from the shaft means, the second casing may be positioned about the first casing freely and without interference from the shaft means, and so that, upon innterconnection of the control lever with the shaft means, the control lever is outward of the first and second casings; wherein the means interconnecting the control lever with the shaft means comprise a removable member interconnecting the control lever and the Shaft means, wherein, with the interconnecting member interconnecting the shaft means and the control lever, and with the second casing so positioned about the first casing, the interconnecting member is disposed through a wall of the first casing and a wall of the second casing.
Claim 2
Dependent Claim
198 words
A mechanism for controlling an engine apparatus comprising: a first casing; shaft means rotatably supported in the first casing; means interconnecting the shaft means and engine apparatus so that the engine apparatus is responsive to movement of the shaft means; a second casing positionable about the first casing; a control lever positioned outward of the first casing; and means interconnecting the control lever with the shaft means, meanwhile allowing disconnection of the control lever from the shaft means so that, upon disconnection of the control lever from the shaft means, the second casing may be positioned about the first casing freely and without interference from the shaft means, and so that, upon innterconnection of the control lever with the shaft means, the control lever is outward of the first and second casings; wherein the means interconnecting the control lever with the shaft means comprise a removable member interconnecting the control lever and the Shaft means, wherein, with the interconnecting member interconnecting the shaft means and the control lever, and with the second casing so positioned about the first casing, the interconnecting member is disposed through a wall of the first casing and a wall of the second casing.
