To all whom may concern:
Be it known that l, GAn) H. Peon, a cltizen of the United States, residing at Waverly, in the county of 'llioga and State of New York, have invented a certain new and useful Improvement in Drill-Steelflurning Devices for Percussive Fluid- Operate Drills, of which thefollowing is a specification.
This invention relates to percussive fluid operated drills and more particularly to a mechanism for giving the drill steel an oscillating movement so that its cutting edges strike difierent portions of the drilled surface in successive blows, resulting in increased drilling efiiciency, and freedom from becoming wedged in the hole.
The object of the invention is to provide a fluid operatedmechanism which enables the drill steel to be automatically oscillated preterahly at aspeed less than the reciprocation of the drill piston. This object is accomplished by mechanism, a practical embodiment of which is shown-in the accompanying drawings in which Figure l showsan exterior view of an air feed stoping drill provided with this mechanism, Fig. 2 shows a longitudinal section through the forward end of the drill inside the oscillating mechanism, Fig. 3 shows a transverse section on a larger scale taken on the line 3-3 of Fig. 2, Fig. t
shows a transverse section taken on the line part of the present invention. in Fig. is own the forward end 2 of the drill cylor the front portion 3 of the piston, drill, here shown, losing of the valveless e, live air entering the front end cl nder through the ports ft. The pisstrilres anvil hloclr 5 theshanlr oil which. projects back into the cylinder and th nvil loloclr in turn actuates by its inn drill steel 6 which lits into a polygo' l in a sleeve 8. 'ihis sleeve 8 is .tahly mounted in a front head casing a 1 J3 J widen secured to the leeward drill cylinder by bolts 10. The rearward portion of the cylinder head casing is of larger diameter and. is bored out to form opposite partially annular cylinder chambers 11 and 12 surrounding the sleeve 8. Keyed t0 the sleeve 8 is a cylindrical piston 13 from which project two diametrically opposite wings 14: and 15 which are adapted to have an oscillating movement in the cylinder chambers 11 and 12. The valve mechanism for oscillating these Wings is as follows: Fluid pressure is admitted and exhausted from the cylinders Hand 12 by means of passages 16 and 17 which lead into the lower part of each of the cylinders. 'lo double the effect of the fluid pressure cross passages 18 and 19ers provided through the piston 13 aflording connection in each direction between the correspondingly operating faces oi. the wings 1d and 15, the wings thus each becoming a double acting piston. The passages 16 and 17 extend inwardly to the rear, and open into a valve chest 20 in which slides a spool valve 2i which has a central depression 22 adapted to connect the passages 16 and 17 alternately with the central fluid inlet passage the valve Ell also havingdepressions 2i and 25 on either side of the depression 22 adapted to alternately connect the passages 16 and 17 with the exhaust passages 26 and 27. To move the valve, smaller live iluid leak ports 28 and 29 are provided which lead from the depression 22 to the opposite ends of the valve chest. These ail'ord a constant pressure in both ends of the valve chest serving" move the valve, which movement is e cted at each end oi the piston stroke by of outlet ports 30 and ill which run to face of the piston 13 are al rnately connected to Ski exhaust passages 3% and 33, which lead to.
the atmosphere, by means of elongated depressions 3stand 35 the lace the ton l3.
The size of the inlet and exhaur the cylinders of this drill stee motor is so calculated tl 13 will oscillate or recipro considerably slower speed than To prevent ler mot-or cylinders oscillating to each trot: the
i enter other-annular pac' W 1 and 3? provided in the ir l the piston lil Paclrin .7 provided in inders and are pressed against the bodv of The operation of the mechanism will be evident from the above description. As the drill steel 6 is struck by the piston it will be given a comparatively slow to and fro oscillation by means of the piston 13 of the oscillating motor. The movement of the piston 13, although, slow, is powerful and prevents any possibility of the drill steel-being caught in the hole. Furthermore, by reason of the fact that the oscillatory movement of the piston is considerably slower than the movement of the drill piston the cutting edges of the drill will strike a new rock surface at every blow of the piston. The slower movement of the oscillating piston also works an economy in the consumption of fluid used in oscillating the steel.
It is to be understood that the present showing and description discloses only one ton, a drill steel actuated by said piston, a
sleeve for holding said steel, a partially annular cylinder surrounding said sleeve, a piston attached to said sleeve and oscillating in said cylinder, and valve mechanism for oscillating said piston and said drill steel at a speed less than said drill piston.
2. In a percussive tool, a cylinder, its piston, a drill steel actuated by said piston, a sleeve for the reception of said drill steel, 9. partially annular cylinder surrounding said sleeve, a wing attached to said sleeve and adapted to oscillate in' said cylinder, and fluid connections for operating said oscillating piston.
3. In a percussive tool, a cylinder, its piston, a drill steel actuated by said piston, a sleeve for the reception of said drill steel, a partially annular cylinder surrounding said sleeve, a wing attached to said sleeve and adapted to oscillate in said cylinder, and a valve for admitting pressure alternately to opposite faces of the Wing to oscillate said wing. sleeve and steel.
4. In a percussive tool, a cylinder, its piston, a drill steel actuated by said piston, a sleeve for the reception of said drill steel, a casing around said sleeve having a pair of opposed partially annular cylinders, a piston attached to said sleeve having oppositely projecting wings, cross passages leading from the cylinder portion on each side of said wings to the portion of the cylinder on the corresponding side of the other wing and fluid passages for admitting fluid to and exhausting it from opposed sides of said wings.
In testimony whereof, I have hereunto set my hand.
