To all 'whom it may concern:
Beit known that I, GEORGE BUENsiDE, a
' subject of the King of Great Britain, residing at Milburn Terrace, Shiney Row, Fence Houses, county of Durham, England, have 'invented a new and useful Safety Boring provements in boring apparatusV designed or the purpose of making long bore holes either'in rock or coal without danger to life and loss of property which frequently results from accidents in operations of this class', and my invention is particularly designed to yrender work of this class saferand more exppditious than heretofore. f 'y invention is also designed particularly for use in connection with old mine workings,
which frequently contain dangerous accumulations of water and gas under pressure, and my said invention is fully disclosed in the following specification of which the accompanying drawings form a part, in which the separate parts of my improvement are designated by suitable reference characters in each of the views, and in whicht Figure 1 is a longitudinal side view of the complete apparatus which I employ and showing the method of operating the same, part of the construction being in section;
1g. 2 a view similar to Fig. 1, but showing all the parts' of theapparatus in horizontal section; Fig. 3 a cross section onthe line 4 a longitudinal section of a compound dri which I employ; Fig. 5 a side elevation of the compound Idrill complete, and Fig. 6 a view similar to Fig.l 1 but showing the initial step in the use of my improved apparatus, in which my com'pound drill is employed.
When beginning old mine workings orborings, l first provide a machine stand or support2, and feed screw 4, provided with a handle 1,. and coupling box 5, all of well known construction, and employ inconnection therewith a compound drill 6, comprismg a main tubular member 6a and a drilll point member 7 of less diameter than the main d rill member, and the main drill member 6% 1s provided with spiral wings Orblades 51, whlch are staggered and overlapped so as to revent clogging in the operation\ of thej dri as l ereinafter described.
The drill point member 7 is of the same construction as the main part, 6L of the compound drill and is provided with similar wings or blades 51, and is screwed into the main member 6a, and is also provided at its outer end with a hole or support 8. The drill point member 7, which is tubular in form as shown in Fig. 4 is also provided with a longitudinal movable tubular valve device 10, which is designed to close the communication between the parts 6a and 7 of the compound drill, and is provided with a spiral spring 9, which normally holds said valve seated, and the said drill point member 7 is provided with interior grooves or ribs 7a whereby water or other liquid is free Y to flow around the'valve 10.
In' ractice the compound drill 6 is connecte with the parts 2 and 4 by means of coupling box 5 as shown in Fi 6, and a drill hole 45 is bored part of whic is of greater diameter than the other whereby an annular shoulder 45a is formed in said drill hole. My invention also involves the details of construction shown in Fi s. 1 to 3 whereby safety boring to any e'sired depth of the bore hole-45 is accomplished. "These details involve a borin tube 41, provided with two metal wedge p ates 17, provided at their outer ends with hooks50, and two su porting plates 18 also referably provi ed at their outer ends with) hooks 50, said wedge plates and supportin plates being ada ted to be placed on the oring tube 41 an 1nserted into the larger part 45b -of' the bore hole. Connected with the outer end of the boring tube 41, isa cross head coupling 13, provided-in its op osite sides with recesses' 14, through whic are passed screws l5, connected with the hooks 50, of the wedge plates 17, and provided with nuts 38,I and by turning the nuts 38 the plates 18 are eX- panded until the apparatus is securely locked in the bore hole 45 f v The inner end of the bore tube 4l, is ro-v vided with a rigid collar 19, and two ac 'ng collars 20, of rubber or other suita le ma'- terial, Vbetween which is placed a loose collar ,n
21, preferably of brass, and before the apparatus is clamped in the bore hole 451 as hereinbefore described the boring tube" 41,l is forced into the bore hole so that thev inner packing ring or collarwill press firmly on thev shoulder 45a, while the packing ring or collar 20 between the stationary' metal collar 19 and brass collar 21, will be expanded outy35 for the casing26a wardly against the walls of the bore 45b and thus make a gas and water ti ht'conneetion. Passing through the tubular oring tube 41, is a boring rod 46, which is connected with 5 the compound drill 6, and is of less diameter than the boring tube 41, and which may be made up of separate sections, connected by couplings 47, and the boring rod 46 is connected with the feed screw 4, by means of a 1UA tubular pump spindle 28, which is connected with the feed screw by means of the coupling box 5, and the pump spindle 28, forms in effect, an eXtension'of the boring rod 4 6, and mounted thereon is a pump 26, comprising a casing 26Et through which the spindle 28 passes and in which is a gland 26h, and the casing 26a is provided with a downwardly directed arm 26c which carries a pump cylinder 26g with the lower end of which is connected a water lpipe 26e, and the arm 26C is provided with a passage 26f, which communicates with the lower end of the cylinder 26d. The cylinder 26dis provided with the usual piston, with which is connected a rod 26g which is connected with a band 26h Inounted'on an eccentric sheave 261, through which the Jpump spindle 28 passes and the said pump spindle is provided with ports or' assages 26j which communicate with the 30 interior of the casing 26a with which the passages 26C in the arm 26e also communicates, and in the casing 26a at the end of the gland 26h is placed a grooved and perforated sleeve 26k which forms an additional packing and around and through which the water flows into the spindle 28. I also provide a coupling tube adapted to vbe connected with the cross head coupling 13 and provided with oppositely directed plug or valve easings 35a having caps through which yare passed screws 37, provided with`hand wheels 34, and with the inner ends of which are connected valve plugs 36, of rubber or other suitable material by means of which Ythe passage through the tubular coupling 35 around the bore rod 46 which passes therethrough may be closed, and connected with the tubular coupling 35, is a valve casing 12 through which the boring rod also passes, 50 and which, isl provided with a valve 12EL lthrough which-said boring rod also passes, and connected with the valve casing 12 `is a stufiing box 22, through which the boring rod 46 passes, and it will be observed that the bores or passages through the boring tube 41, the cross head coupling 13, the tubular coupling 35, the valve easing 12, and the valve 12a are all of the same size and much larger in diameter tha-n the boring rod 46. A drain pipe 11 is connected with the coupling tube 35, adjacent to the cross head coupling 13, and provided with a valve 11a, and a pressure gage 16 is connected with the cross head coupling 13; In practice the compound drill 6 is rst ated either by the handle 1 or in an other g used as shown in Fig. 6 to bore the holes45 and 45') to a predetermined depth thus forme ing the shoulder 45u. Iii'this operation, the machine stand or support 2 is mounted at the desired point in the mine chamber and is- ,'i rigidly held in place by means of a screw device 2? adapted to bear on or enter the roof wall of the mine. After the boring holes 45 and 45b are bored to a suitable depth the compound drill 6 is detached from the feed screw 4, and the boring tube 41 having the expansion plates 18 and wedge plates 1.7 mounted therein is inserted so that the packing rings 20 will form a tight joint around the inner end of said boring tube as herein before described, and all the parts oi the apparatus are assembled as shown in Figs. 1 and 2, and the nuts 38 are turned so as to pull the wedge plates 17 outwardly and eX- paiid the plates 18 and hold the apparatus iirmly in position. In assembling the parts as shown in Figs. 1 and 2, the part 6u of the compound drill is left out and the part 7 only emp oyed and this may be made of any desired length by connecting separate parts. 9@ In connection with the machine stand or i support 2 a tapped feed nut 42 is also enh ployed through which the feed screw passes,
and inY practice the feed screw may be opersuitable way, or by means of a power c evice if desired. When the feed screw 4 is turned as. described the drill 7 is fed forwardly and the hole 45 is bored to the desired depth and in this operation water is pumped up through the pump 26 and through the drill rod 46- and through the drill 7, and asses out through the aperture 8 where it mingles with the debris produced by the drill point, flows ,back through the bore tube 41 to the dis- 155 charge pipe 11. In this operation the ump is preventedfrom turning on the s in e 28 by. means of `a rod 3 connected wit the machine stand or support 2 and with the valve casing 12 at 32, and passing through a guide 11@ 3a connected with the'casing 26a of the pump and through which the rod 3 passes. The drill or drill point 7, as shown in Figs. 1 and 2, may be made either with double or single wings or blades 51, and to avoid clogging, 11.5; parts of the wings or blades are cut away I so that the parts remaining will overlap in such manner as to permit the liquid and debris to pass back throu h the boring tube 41.
It -will be. understoo that the valve 10 120 and spring 9 is used in the part of the drill` as shown in Figs. 1 and 2,' and the object thereof is to avoid the inside of the boring rod 46 fnom becoming clo ged when being inserted into, the bore ho e 8. Whenever necessary theboring rod may be disconnected from y the pump spindle 28 which forms a continuation thereof, and a new sec-. tion of boring rod inserted so as to enable the boring to continue, and this may be 13e beindicated by the gage 16.
done Without interfering in any Way with the other parts of the apparatus, and this operation may be continued until the desired depth of boring is reached,l or until old workings or mine chambers are bored into, and in this case the pressure of gases or air in such old workings or mine chambers will Should there be an outrush of gas or water at any time While the stuiiing box 22 is disconnected for any pur ose, the valve plugs 36 may be manipulate for closing the passage through the bore tube al, `and the valve l2a may be used lfor closing the passage through the bore tube 4l and parts connected therewith when -the boring rod 46 is withdrawn for 'any purose. Having fully described my invention, what ll claim as new and desire to secure by Letters Patent, is :f-
lf. In a boring `apparatus of vthe class described, a tubular boring rod, a screw for feeding the same forwardly, a pump mounted on a movable spindle connected with saidv rod and said feed screw, means whereby the pump is operated by the operation of said feed screWLspindle and boring rod, andl means to prevent the pump from turning with said parts.
2. ln a boring apparatus of the class de- 30 scribed a tubular drill provided at one end with a point and at the other end with an inner annular shoulder, and a valve movable 'in said drill and provided with a spring it is normally held seated on said 35 eccentric disk bywhich the piston of the 40 pump is operated, and the cylinder of the. pump being in communication with the interior of said spindle.
