Although the time may arrive for a pocket to open,it will not do so until the trip-rod lever actually sets the lower dogP, Pi, etc., against the ratchet wheel. This sequence is controlledby the setting of the crank U, on devices B and B2, and the adjust-ment of the rods T and jT, so that the ratchet wheel is placed inposition for pocket charging for each quarter revolution of thereducing gear M (Fig. 24). 58. Sharpening Device.—The sharpening device is shown atJV, Fig. 20, and in detail in Fig. 26. This device is moved across. Fig. 20. the face of the stone by means of a hydraulic cylinder, whichprojects out horizontally from between the wood burr A is fastened in the holder B, similar to the hand-fedgrinder sharpening device, except that it is in a vertical burr carriage C is supported on two ways D, and the inten-sity of pressure of the burr against the grindstone is controlledby manual adjustment device E, on top of the burr carriage. Thetravel of the carriage is controlled by levers Pi and F2, whichoperate the valve G. With the levers as shown, the piston H isat rest. By opening the port Ki to pressure-water inlet, the pistonwill move to the left, and the burr carriage with it, while waterwill be discharged through port iv2 from the cylinder. The twolevers enable the operator to stand close to the stone he is apparatus can also be applied to a single stone. Duringsharpening wi
