Patented July 26, 1938 UNITEDL STATES DRILL CLEANSING DEVICE Ernest H. Dickenson, New York, N. Y., assignor to Ingersoll-Rand Company, Jersey City, N. J., a corporation of New Jersey Application March 11, 1937, Serial No. 130,312
3 Claims.
This invention relates to cleansing devices, and more particularly to a cleansing device for removing detritus in a dry state, from a drill hole.
One object of the invention is to prevent the passage or expulsion of rock cuttings or dust to the atmosphere.
Another object is to eliminate the need of encumbering dust collecting devices adjacent the drill hole in order to maintain a lclean working surface and to prevent the intermingling of dust with the atmosphere.
Other objects will be in part obvio-us and in part pointed out hereinafter.
In the drawing accompanying this specification and in which similar reference numerals refer to similar parts,
Figure 1 is a side elevation of a rockdrill having the invention applied thereto,
Figure 2 is an elevation, in section, of a rock drill constructed in accordance with the practice of the invention,
Figure 3 is a transverse view taken through Figure 2 on the line 3-3, and
Figure 4 is an elevation, partly broken away, of a modified form of the invention.
Referring more particularly to the drawing, the invention is shown applied toI a rock drilling mechanism 20 illustrated as being of the stoper type commonly used for drilling holes above the horizontal, as in the roof of a drift. 'I'he rock drill 20 accordingly comprises a percussive motor 2| and an extensible pressure actuated feeding motor 22,comprising a cylinder I8 and apiston I 9, which supports and advances the percussive motor in a well understood manner. The feeding motor may be provided with a suitable throttle valve I 1 for controlling the iiow of pressure fluid into and from the cylinder I8.
The rock drill is further provided with a handle 23 which may be grasped b-y the operator to rotate the rock drill and thus also a reciprocable working implement 24 which the rock drill is intended to actuate.
'I'he percussive motor 2|, shown for illustrative purposes, comprises a cylinder 25 which may be suitably secured to a head 26 constituting also a head for the feeding motor and a support for the handle 23. Within the cylinder is a piston chamber 21 containing a reciprocatory hammer piston 28, and in the wall of the cylinder 25 is a free exhaust port 29 which is controlled by the piston 28.
In the front end of the cylinder and in direct communication with the piston chamber 21 is an enlarged bore or recess 30 to accommodate an (Cl. Z55-50) anvil block 3| against which the blows of the hammer piston are delivered. y
The periphery of the anvil block 3| may, as illustrated, be in slidable engagement with the wall of the recess 30, and on the front end of the anvil block is an extension 32 which extends slidably througha head 33 forming a closure for the front end of the cylinder. In the vstructure shown the portion of the extension 32 lying in the planeof the closure 33 is of polygonal shape and the bore in the closure 33 through which the extension extends is of corresponding shape so thatthe two will'be suitably interlocked to prevent rotary movement of the anvil block with respect to the cylinder.
Secured to the free end of the extension 32, as by threaded engagement, is a sleeve or chuck 34 to receive slidably the shank 35 of the working implement 24, and arranged within the front end of the chuck 34 is a packing member 36 which bears against the surface of the working implement to prevent the entrance of abrasive materialv between the surfaces of the chuck 34 and the f and through the anvil block 3| and the extension 32 is a passage 39 which, in the assembled and operative positions of the parts, registers with the passage 40 in the working implement 24.
The passages 39 and 40 may, if desired, be of the same cross sectional area so that cuttings entering the passage 4I) may pass directly into and through the passage l39, it being understood that in the operative position of the parts the front end of the extension 32 will seat against the adjacent surface of the working implement to providea direct path for the transmission of the blows of the hammer piston to the cutting end of the working implement. Thus the working implement and the anvil block and its extensions may serve as a conduit for conveying the cuttings from the drill hole.
Any suitable means, as for example a centrifugal pump 4I driven by a motor I6, may be employed for drawing the cuttings through the drilling mechanism. The pump is connected With the rear or free end of the stem 31 by a hose 42, and a separating device 43 may be interposed in the hose to eiect the removal of solid matter from the air stream.
The distribution of pressure fluid to the pisto-n chamber 21 is eifected, in the present instance, by an oscillatory plate valve 44 arranged on the side of the cylinder 2|. The valve 44 controls front and rear inlet passages 45 and 46, respectively, and is encased by a valve chest 41 into which the pressure fluid intended to be distributed is introduced by a conduit 48 threaded to the valve chest.
In the modified form of the invention, illustrated in Figure 4 the drilling and feeding motors and, therefore, the anvil block and its ezi tensions, are arranged coaxially with each other. In order, therefore, to enable the conduit 42 to be conveniently connected to the stem 31"and permit its free reciprocation with the anvil blockv the cylinder I8 of the feeding motor is provided with a hollow extension 49 which is connectedto In the side of the extension 49 is 4 an aperture 50 through which the conduit 42 may the head 2B.
extend for connection with the stem 31.
In view of the foregoing description it is believed that the operation of the device will be obvious. It may be briefly stated, however,.that
Y when the drilling mechanism and the pump are in operation the suction created by the latter will carry the detritus from the drill hole through the drilling mechanism and thereby prevent the dissemination of dust in thevatmosphere.
I claim:
1. In a hole cleansing device, the combination of a reciprocable working implement having a bore extending entirely therethrough and a motor having a reciprocatory hammer piston for actuating the working implement, means extending through the motor for transmitting the blows of the hammer piston to the working implement and having a bore to register with the first said bore, and evacuating means attached to the first mentioned means for withdrawing cuttings from a drill hole through the bores.
2. yIn *a holecleansing device, the combination of a reciprocable working implement having an axial passage extending entirely therethrough `1vand a. motor having a reciprocatory hammer piston, means in the motor for transmitting the blows of the hammer piston tol the working imp'lement having a passage to communicate with the'interior of the working implement, and evac- -uating means for withdrawing cutting from a drill hole through the Working implement and lthe passage.
