The hydraulic circuit referred to in paragraph 26 also includes the tube pawl operating cylinder and the tripping cam operating cylinder (rack pawl mechanism). This portion of the circuit is arranged with semiautomatic control separate from the cradle operating valve. It includes, in addition to the two operating cylinders, a pilot valve lICf!located at the upper end adjacent to the cradle control valve, and an operatingvalve "K" located on the tube above the tripping camoperating cylinder.

246 32. The hydraulic arrangement of these elements is shown on the diagrams of figures 45 to 48, inclusive. Valve IICIIis the direction control valve. It is manually positioned from IIHoistll to IILowerllin order to set the pawl mechanisms to opera te for the reverse cycle. When in either position it is locked by a solenoid plunger which is energized by either of two switches. These are located at the two hoist controls and function to interlock lever IICIIwhenever the control is moved from neutral. (See drs. no. 234274 and 234275 and par. 38.) 33. Operating valve IIKIIis arranged to be actuated by movement of the rack (when lever "ell is in lowering position only). (See fig. 48.) This is accomplished by a cam surface (fig. 43) on a rack connecting bar (located immediately above the upper intermediate rack pawl). This cam surface contacts and lifts a roller and cam lever in the final four inches of upward rack mov.ement. At that position the rack pawls are projecting to lift projectiles supported on the tube pawls and as the load is relieved from the latter, valve IIKIIis moved (by the cam lever), pressure is ported to the tube pawl operatingcylinder, and those pawls are retracted to permit the descending projectiles to pass. Each tube pawl moves back into the hoistway as the passing projectile is lowered and thus is positioned (by spring) to receive the proj ectile from the stage above. At the bottom of the stroke the tripping cams retract the rack pawls as the load is again taken by the tube pawls. Hoist e6ntrols, Interlocks and Indicators 34. Thehoist controls, interlocks and indicator devices include the arrangements described in the cradle assembly text, paragraphs 20-c, 20-d, the cradle operating control, paragraphs 25-' 26, the pawl control devices, paragraphs 27-31, and the main circuit hoist controls and signal devices described below. 35. The main hoist control comprises dupl Lcat e installations of control handles with their respective mechanical interlock, eiectrical interlock and audi-ble and visual signals. The control stations are adjacent to the hoist loading apertures on the upper and lower projectile handling flats. Typical arrangements are as shown on drawings number 234278 and 234279. 36. Control handle station. - The control handles are mounted on shaft brackets which also function as mountings for the interlock and indicator devices and for the vertical control shaft that extends upward to the A-end. Tilting box angleof-tilt adjustments are obtained through bevel gear and spur gear train (dr. no. 234276) from the control shaft with shaft rota tion and equivalent til t as indicated in the following description of control handle limits of movement.
