Abstract: 1,014,909. Valves; fluid pressure brakes; controlling; clutch-brake combinations. HAMILTON CONTROLLERS Ltd. Nov. 18, 1964 [Oct. 28, 1963], No. 42412/63. Headings F2F, F2L and F2V. A two-position spool valve actuated by pneumatic pressure comprises a four-part housing 1-4 within which is mounted a spool 8 having one end 9 working in a chamber 15 and the other end 11 co-operating with a piston 18- 20 slidable in a cylinder 17 and biased away from the spool by a spring 22, the piston having a larger effective area than the end 9. The housing is provided with an inlet 26, outlets 25, 27, exhaust openings 31, 32, a passage 33 connectable to a port 16 leading to chamber 15 and a port 24 to the cylinder. When air is admitted to the cylinder, the spool moves to the left, and on exhausting the cylinder the piston returns under the action of the spring so that air subsequently admitted to the chamber to return the spool does not have to overcome the inertia of the piston, consequently the spool returns rapidly. In Fig. 5, the valve is shown controlling the supply of air to and from a brake 44 and a clutch 45 of a loom, the brake being connected to outlet 25 and the clutch to outlet 27. A manually operated valve 50 controls the supply to and from the cylinder and a solenoid actuated three-way valve 53 controls alternately the connection between ports 35 and 16 and the connection between port 35 and a manually operated valve 55. The sources of air are shown at 51. In operation, with the valve positioned as in Fig.2, the brake is engaged and the clutch disengaged, the solenoid valve is de-energized to shut off the connection between ports 35 and 16 and open the chamber to exhaust via valve 55. To start the loom, valve 50 is actuated to admit air to the cylinder to move the spool to the left thereby connecting the brake operating cylinder 46 to exhaust and the clutch operating cylinder 45 to the supply port 26; on releasing the valve 50 the cylinder 17 exhausts and the piston returns. To stop the loom, the solenoid valve is actuated to admit air to the chamber via port 35. If it is required to " inch " the loom, the solenoid valve is deenergized, valve 55 is adjusted to supply air to the chamber and by actuating valve 50 the loom can be started, the air in the chamber serving to return the spool as soon as the cylinder 17 is exhausted.
