Patent GB-222837-A (GB)
Abstract: 222,837. K÷ster, E. W. Oct. 3, 1923, [Convention date]. Clutches, friction; controlling clutches. - A compressor is coupled to and uncoupled from its driving mechanism by a clutch controlled by the compressed medium, the compressor shaft carrying a piston on which slides a cylinder fixed to the axially moving clutch member. Fig. 1 shows a compressor driven by a continuously rotated pulley &c. 3 loose on the compressor shaft and integral with one member 4 of the clutch. The end of the shaft forms a piston 7 on which slides a cylinder 6 fixed to the hub of the other clutch member 5 which is keyed to the shaft. A spring 8 thrusts the clutch parts together, but at a certain pressure is overcome by the pressure of the medium delivered to the end of the cylinder through a pipe 9. According to the Specification as open to inspection under Sect. 91 (3) (a), Fig. 2 (Cancelled) shows a clutch in which the part 5 slides on a shaft 10 in line with the compressor shaft 1 and is acted upon by a spring 11 and a lever 12, 13, the arm 13 being linked to a piston within a cylinder to which pressure medium is admitted by a spring-pressed valve 17 when a certain pressure is reached, the valve allowing relief of the cylinder to atmosphere through a port 21 at lower pressures. The lever 12, 13 may be moved by hand, or locked in position. An electromagnetic clutch may be used, controlled by a contact manometer. This subject-matter does not appear in the Specification as accepted.
