Abstract
Abstract Means for trimming the position of a controlled element responsive to a power-actuated controller having a rotatable shaft for causing actuation of the controlled element. A housing member is journaled on the controller shaft and includes a part which is connected to the controlled element. The housing member has a shaft journaled thereto which is spaced from the controller shaft. Meshing gears interconnect the housing member shaft and the controller shaft. A power actuated unit is carried by the housing member and serves to rotate the housing member shaft. The degree of rotation of the housing member shaft is monitored by a signal device carried by the housing member.

Claims Analysis
Total Claims: 13
Claim 1
Independent Claim
106 words
Position-trimming mEans adapted for operable connection with a controlled element responsive to a power-actuated controller having a rotatable shaft for actuating said controlled element comprising: a housing member adapted for journaling on said controller shaft and including a part connectable to said controlled element, a driven shaft journaled in said housing member, meshing gear means having one part carried by said driven shaft and having another part connectable to said controller shaft, a power-actuated unit carried by said housing member connected to said driven shaft to impart rotation thereto, and signal means responsive to the rotative position of said driven shaft relative to the housing member.
Claim 2
Dependent Claim
106 words
Position-trimming mEans adapted for operable connection with a controlled element responsive to a power-actuated controller having a rotatable shaft for actuating said controlled element comprising: a housing member adapted for journaling on said controller shaft and including a part connectable to said controlled element, a driven shaft journaled in said housing member, meshing gear means having one part carried by said driven shaft and having another part connectable to said controller shaft, a power-actuated unit carried by said housing member connected to said driven shaft to impart rotation thereto, and signal means responsive to the rotative position of said driven shaft relative to the housing member.
Claim 3
Dependent Claim
37 words
The construction of claim 1, wherein said power-actuated unit includes a drive shaft spaced from said driven shaft and operatively connected thereto by gearing, one end portion of said driven shaft having said signal means connected thereto.
Claim 4
Dependent Claim
58 words
The construction of claim 2, including limit switch means electrically connected to said power-actuated unit to cause deactivation of said unit when tripped, said switch means being mounted to said housing member adjacent said driven shaft, said driven shaft carrying a switch tripping part operatively engageable with said switch means upon selected rotational movement of said driven shaft.
Claim 5
Dependent Claim
28 words
The construction of claim 2, wherein said signal means includes an actuator member, a flexible coupling connecting said driven shaft end portion to said signal means actuator member.
Claim 6
Dependent Claim
45 words
The construction of claim 1, wherein said gear means includes a worm gear carried on said driven shaft and a pivot arm having one end adapted for attachment to said controller shaft and its other end comprising a gear sector interengaging with said worm gear.
Claim 7
Dependent Claim
24 words
The construction of claim 5, including first stop means mounted to said housing member and positioned within the path of swing of said arm.
Claim 8
Dependent Claim
38 words
The construction of claim 6, including second stop means carried by said driven shaft and positioned within the path of swing of said arm, said first and second stop means being located on opposite sides of said arm.
Claim 9
Dependent Claim
24 words
The construction of claim 7, wherein one of said stop means is shiftable so as to vary the amount of swing of said arm.
Claim 10
Dependent Claim
42 words
The construction of claim 5, wherein said arm has a bore formed therein and includes an adapter received within said bore, said adapter having a bore to receive said controller shaft and being securable to both said arm and said controller shaft.
Claim 11
Dependent Claim
30 words
The construction of claim 9, wherein said arm and adapter have registering passages formed therein, a lock pin pressed into said registering passages to secure said adapter to said arm.
Claim 12
Dependent Claim
31 words
The construction of claim 10, and including screw means threaded through said arm and adapter adapted to engage said controller shaft for securing said adapter to said arm and controller shaft.
Claim 13
Dependent Claim
27 words
The construction of claim 1, and including means mounted to said driven shaft externally of said housing for indicating the degree of rotation of said driven shaft.
