ordinary functions of a crane in supporting a 1 J 2 permits the spring toagain open the valve.

I I O weight.

The outer arm of the jib-crane is especiall 5 designed to resist the peculiar strains to which it is subjected by reason of the fact that it forms a part of a drilling or countersinking a aratus, having-not only to support consldbrable wei ht, but also to resist at times an' u ward t ust due to the pressure of the rill u on the work below it. For this purpose-an to preserve at all times the alinement of' the tool the bracing-irons E E are of special value and importance, and

they are also of importance in'connection with a hoisting mechanism preferably supported on the crane-arm, as shown, and by means of which the work can bepartially supported or transported.

With reference" to the drilhng apparatus proper it will be understood that the spindle G supporting the drilling or countersmking tool G at its end,-i s actuated through the worm-gear G and the connections -to the motor M and is normally held in elevated position by the action of the springs G When it is desired to bring the tool into operation, the'operator grasping'the handles it and k of the frame shifts the arms of the jib-crane so as to bring the tool into roper alinement with the work and presses the tool downward into contact with the work, the downwardmotion ofthe frame being communicated to the tool through its arms H H: and the trunnion-pins G.G The operator next draws'inward the grip-lever K, compressing the spring K and forcingthe compound rod made u of the rods K sleeve K, and fork'K outwar moving the valve K upward in the casing J 3 so as to openthe connection between the portsJ and J", permitting the ressure fluid to flow into the flexible conduit I and through it into the cylinder I, where, actin upon the piston and through the piston-r0 I itico'mmunicates its pressure to the frame comprising the levers H H and through these levers to the drill-spindle and tool. The

pressure admitted to the port J 6 of the cylinder 1s communicated through the channel ,or port J to the chamber J and acts upon the top of the valve K, and whenever this complishedby the compression-of this spring and the incidental sliding of the sleeve K on the end. of thejrodKTuntiI ort J thus cutting of! further 'ad inission 'of fluid until the pressure in-cylinder I and chamber As soon as the drilling or countersinking is is closed,

Normallyboth of the valves 0', and Q are closed .,When it is desired to admit pressure fluid to the cylinder and draw up the hoisting-chain, thespin'dle Ois turned-1n the and spin-- -dle to normal non-operative position.

- chain is released, the valve will automatically close cutting off further supplies to the hoisting-cylinder, and whenever it is desired to release the fluid in the cylinder the spindle O is turned in the direction to raise the arm 0, which lifts the valve 0 from its seat, permitting the fluid in the cylinder to ex-. haust through the chamber 0* and port 0.
