BRAKE MECHANISM
Document Type and Number:
Japanese Patent JPS5846418
Kind Code:
A
Abstract:
A brake mechanism (10) operable to maintain an air operable control drive mechanism (12) in position in the event of failure of the air supply is disclosed. A first rack section (22) is attached to a control lever (16) of the control drive mechanism (12) and is engagable in any operable position of the control lever (16) by a second arcuate rack section (24). A compression spring (62) acting on a toggle mechanism (28) biases the racks into engagement, and an air cylinder assembly (26) acting on the toggle mechanism (28) against the compression spring (62) maintains the second rack section (24) out of engagement with the first rack section (22) so long as the air supply to the air cylinder assembly (26) is maintained.
