HOLE-CLEANSING MECHANISM.
Application filed July 12, 1920. Serial No. 395,729.
My invention relates to hole cleansing mechanisms and more especially to improved hole cleansing mechanisms for use on rock drilling devices.
An object of my invention is to provide an improved hole cleansing mechanism. Another object of my invention is to provide an improved control mechanism for use with such devices on rock drilling machinery. A further object of my invention is to provide animproved hole cleansing mechanism for use in rock drilling machinery in which a single tube for the conveyance of the cleansing fluids to a hollow steel may be used without danger of flooding the drill. Other objects of my invention will appear hereinafter.
In the accompanying drawings, I have shown for purposes of illustration one embodiment which my invention may assume in practice.
In these drawings,
Fig. 1 is a central section through the rear end of the cylinder and rear head block of a fluid pressure motor used for rock drilling purposes.
Fig. 2 is a transverse section taken on the line 22 of Fig. 1.
V Fig. 3 is a detail view in elevation of the valve sleeve, the position of the sleeve corresponding to that shown in Fig. 1 but the parts being shown on a slightly larger scale.
Fig. & is a fragmentary view similar to that shown in Fig. 3 but with the sleeve turned through an angle of approximately 90, to show the appearance thereof from a diflerent point of view.
Fig. 5 is a view in elevation of my improved valve member, the same being shown in a position corresponding to its closed posi-- tion when in use.
Figures. 6, 7 and 8 are serial views, each showing sections taken respectively on lines corresponding to the lines aa, b-?) and 00 of Figs. 3 and 5 and showing the relative positions of the parts when the valve is in ofl position, when the valve is in a position to blow out the hole and when the valve is in such position as to provide full pressure to the motor. 7 In its illustrative form my improved con trol mechanism is shown in combination with a fluid pressure drilling motor having a cylinder member 1, a portion of which is shown in Fig. 1, the rear end of the cylinder member being closed by a head block 2 and there being reciprocable within said cylinder a piston 3 provided with a longitudinally extending bore a through which a cleansing fluid supplytube5 extends in a well-known man ner to conduct cleansing fluid to a hollow drill steel.
The head block is provided with a pair of oppositely disposed fluid pressure supply passages ;6, 6, for conducting motive fluid t0 the drill cylinder, one or more of these passages being employed as may be desired in accordance with the power which is required of the drill. The head block is likewise bored out coaxially with the cylinder as indicated at 7 to receive a gland plug 8. The gland plug is generally cylindrical in shape, and is eX- teriorly threaded on its forward end to engage threads formed in the bore 7 the threaded connections as a wholebeing designated 9. The extreme forward end of the gland plug is bored out as indicated at 10 to provide a socket for the reception of the rear end of the tube 5 and a suitable packing gasket 11 surrounds the tube and is squeezed into fluid tight engagement therewith when the gland plug is screwed into its intended position. At a point approximately midway of its length, the gland plug is traversed by a diametrically arranged port 12 which communicates at its opposite ends with an annular groove 13 formed in the periphery of the plug, and from the central portion of the passage 12, a passage 14 extends forward to communicate with the rear end of the cleansing fluid tube 5. Immediately to the rear of the passage 12 and groove 13, there is arranged an annuar collar 15 seating against the rear end of the head block 2. A second annular groove is arranged in the exterior periphery of the gland plug 8 to the rear of the collar 15, this groove being. designated 16. A second collar 17 is arranged immediately adjacent the rear end of the gland plug and consti- 100 tutes a tight fit for a bore 19 in a water connection member 18. The water connecion is provided with a passage 20 communieating with the bore 19 at a point intermediate the collars 15 and 17 lVater is sup- 105 plied to the passage 20 from a suitable supply line 21.. The bore 19 is enlarged as shown at 22 adjacent its forward end and with this enlargement, a passage 23 communicates. Disposed at the top of the head 110 block is a conical chamber 24 in which is secured a conical valve sleeve 25. The exterior periphery of the valve sleeve is provided with a longitudinal groove 26 and, at a point removed angularly therefrom, with a passage 27 passing radially through the sleeve and communicating at its outer end with a passage way 28 which connects to the passage 23. The passage 27 is arranged in the same transverse plane as the upper end of the groove 26 and a second port 29 is drilled within the outlines of the groove 26 through the remaining portion of the sleeve in the same plane as the port 27. A third port 30 is drilled through to the inside of the sleeve at the lower end of the groove 26. The valve is also traversed adjacent its larger end by a pair of ports 31 and 31. communicating respectively with the fluid pressure supply passages 6 and 6.
Itotatable within the valve sleeve is a valve member 32 likewise of generally conical form, this member being hollow as indicated at 38 and traversed by three ports, two of which are designated 34: and 34: and are adapted to communicate with the passages 31 and 31, communicating with the supply passages to the motor cylinder. The third passage, designated 35, passes through the wall of the valve at plane corresponding to-the plane of the port 30 and is adapted to communicate with the port 30 in one position of the valve. The valve is also provided with an external groove 36 arranged in a plane corresponding to the plane of the ports 27 and 29. The relative position of these parts may be noted from Fig. 6, which will disclose that the port 85 is so arranged as to come into communication with the port 30 prior to the moment when the groove 36 connects the ports 27 and 29, and that the ports 34L and 34 are not brought into communication with either of the ports 31 or 31 before the groove 36 has connected the ports 27 and 29. It will be obvious, however, from an inspection of Fig. 8, that the groove 86 is of such length as to remain in communication with both ports 27 and 29 during the entire time when air is admitted to the motor. in passage connects the groove 26 in the valve sleeve with the annular groove 13 formed in the gland plug, this passage being designated 37 and serving to conduct air and water to the cleansing fluid tube 5.
The operation out this device will be obvious from the foregoing description. Assuming that the parts are initially in the position generally indicated in Fig. 6, it will be noted that no air is supplied to either the motor or to the tube and that no water is supplied to the tube. Upon a relatively slight counter-clockwise rotation of the valve, however, the port 35 will be brought into communication with the port 30 and air will be transmitted from the interior of the valve through the ports 35 and 30 to the longitudinally extending groove 26 and will be conducted thence to the, port 37 and so by way of passages 13, 14 and tube 5, to a hollow steel. Upon slightly further rotation of the valve, the supply of air to the tube will be closed, the
a port 35 being moved out of communication with the port 30. Immediately after the closure of this communication, the groove 36 will connect ports 27 and 29 and cleansing liquid passing through port 20, groove 19, enlargement 22, port 28, passage 28- and thence by way of the groove 36 from port 27 to port 29 and to passage 37, will be conducted to the tube. Still further rotation of the valve in counter-clockwise direction will maintain the liquid supply to the tube and will open first one and then both of the air supply passages to the motor. It will be obvious that upon reverse rotation of the valve, the events will be passed through in opposite order, namely, the air to the motor will first be out oh, the water to the steel will next be discontinued, a pufi of air will pass through the steel to blow out the Water, and finally the air supply to the steel will be closed and the drill will be entirely shut down.
From the foregoing description, it will be obvious that I have provided a mechanism in which a single valve serves to supply both air and water to a single cleansing fluid supply tube in such manner that there is no possible communication between the air and water supplies, and in such manner that at the time that water is supplied, the port through which the air is normally supplied is blanked off by the surface of the valve member.
While I have in this application specifi-' cally described one form which my invention may assume in practice,.it will be un: derstood that this form of the same is shown for purposes of illustration and that the invention may be modified and embodiedin other forms without departing from its spirit or the scope of the appended claims:
