ROCK-DRILL.
Specification of Letters Patent.
Application filed November 16, 1907. Serial No. 402,535.
,To ill whom il may concern.'
lie .it known that l, AnnisoN AVERY, citizen of the United States, residing at (Thicago, in the county of Cook and State of illinois, have invented certain new and useful Improvements in Rock-Drills, of which the following is a specification.
My invention is an im )rovement in rock drills, and the objects o my improvement are, first, to increase the etliciency of existing devices; and, second, toprcvide electrical means for applying'heat in the locality of the cutter-head.
An important` feature of .my improvenient consists in a fluid deflector at one end of the engine to deflect the fluid outwardly.
With the above andother objects in view, this invention consists in the novel features and in the combination and arrangement of parts hereinafter more specifically described, illustrated `in the drawings, and particularly pointed out in the claims hereunto appended.
In describing the invention in detail reference is had to the accompanying drawings forming a part of th1s specification wherein like numerals of reference indicate corresponding arts throughout the several lviews, and in W ich Figure 1 is a vertical central section partlyin elevation. Fig. 2 is a cross section 011 line 2 2 of F1 l. Fig. 3 is a section on line 3 3 of ig. 1. Fig. 4t is a section on line 4 4 of Fig. 1.' Fig. 5is an elevation partly broken away of the upper portion of the device shown in Fig. 1, and Fig. G is a section on line 6 6 of Fior. 5. i
n embodiment yof my invention will now be described.
'The reference numeral 5 denotes a supply pipe or drill rod made of pipe which serves as a [luid inlet to conduct the power Iiuid to the fluid-pressure lmotor through fluid passage G into the interjacent passage T, situated between the'` exhaust chamber 8, and the dustpassage i). A rotary motor is secured to the lower end of the casing 10 with its piston drum preferably disposed axially of the casing. The 'motor shown consists of a shell 11, with a cylinder 12 eccentric therein. -'1`he`piston,drum`13 is mounted in bearings in the upper head 14, and the lower head 15, axially of the shell. The piston drum is fitted with a plurality of piston blades 1'6, in slotslG (shown in 'desired construction.
Fig. 2). By disposing the slots 16 on opposite sides of the longitudinal axis of the piston drum and extending them past the axis of the drum a greater exposure of blade to the power fluid is possible. This construction gives a greater power than is otherwise obtainable from an engine of small diameter. 'lhe upper and lower cylinder heads are secured to the cylinder h v screw threaded connection. The upperiieadA 14 is secured to the lower end of the supply pipe 5 by means of screw threads. A segment of the upper head is cut away to provide a continuation upward or outward of the dust chamber, and the lower head is correspondingly cut away to permit' the fluid to pass out at thelower end of theI Patented J au. 4, 1910.
cave upper surface to turn the iiuid outwardly. The' detlector is secured .to the casing preferably b means of a screw, shownin Fig. 1.. ln the region of the cutter-head 20 'there is provided a hea-ting element 21 which may be of any` suitable or The fori shown in Fig. 1 is a coil of high-resistance wire connected at each end with a suitable conductor of electricity 22 and 23, thus giving anall lnetallic circuit for the current of electricity. Should the material at'the drill head become frozen byl the expansion of coinpresed air or otherwise, it is desirable to have means available to thaw the saine.
Anti-friction balls 24 are placed between recessed 'bearing Q5 of the upper head 14 and the upper end of the pistou drum. The cutter-head is provided with a plurality of openings 2G longitudinally therethrough for the purpose of withdrawing the dust. and cuttings from the path of the head. This is effected by the suction of the outrushing fluid through the dust passage. As indicated, the cutter-head is tubular and is actuated by the 'fluid pressure motor. The cutting surfaceearries earhorundum points or other material of a sufiicient degree of hard; ness. The piston bladesare yurged out'- wardly by a length of wire curved length'- wise and placed 1n the radial slot before the blade is inserted, shown at 27 (Fig. 2).
The` reference character 19 indicates the cut away portion ofthe deliector to permit the dust to pass back through. the dust y passage.
In operation, the fluid, underipressure, is delivered into the pipe 5 passing to the motor, and effects the rapid rotation of the cutter-head in a manner well known. VThe dust and cuttings are withdrawn by the outward current induced by the outrushing' Huid through the dust passage of the motor.
vThe casing may be fed downwardly as required by the progress of the work.
Manifestly, changes 1in the form and arrangement of parts may be resorted to without departing from the spirit and sco e of my invention. Therefore, I do not imit myself to the exact construction shown and described in the preferred form of my improvement.
Havingthus fully described my invention, what I'claim as new, and desire to secure by Letters-Patent, is;
1. In an engine of the class described, the
apertured cutter-head rotated by the motor,
in combination with an electrical heat element in the region of the cutter-head.
motor, in combination with an electrical heat element in the region ofthecutterhead.
4. In a rock drill, a fluid ressure motor, a fiuid defiector near one end of the motor,
and an apertured cutter-head rotated by the` motor, inl combination with anv electrical heat element in the region ofthe cutter` head.
In testimony whereof I aix my signature in presence of two witnesses.
