JOHN NORTH, OF NEW YORK, N. Y., ASSIGNOB TO THE AMERICAN DIAMOND- DRILL COMPANY.
IMPROVEMENT IN MAGHiNES FQR DRiLLlNG ROCK.
N Specification forming part of Letters Patent No. 1341,305 dated December 24, 1872.
To all whom it may concern:
Be it known that I, JOHN NORTH, of New York, in the county of New York and State of New York, have invented certain new and useful Improvements in Diamond Rock-Drills, of which the following is a specification:
This invention relates to that class of machines for boring or drilling rock in which diamond drills are employed as a boring medium. The first feature of my invention relates to a nove1 method of imparting aprogressive and rotary movement to the drill-spindle; and it consists in the employment, in connection with an externally screw-threaded drill-spindle, of a revolving sleeve for imparting a progressive or sliding movement to the spindle for advancing or retracting it from its work, and of a second-- ary sleeve for rotating the spindle. The second feature of my invention consists in the provision of a clutch device'for connecting the drill-spindle to the sleeve, for imparting a rotary movement to the same and for disconnecting the spindle from the sleeve for the purpose of enabling the spindle to be retracted at the end of its stroke. The third feature of my invention consists in the employment of difi'erential bevel-gearing for revolving the feedingsleeve, said gearing being so arranged that the feeding-sleeve will revolve at a diminished speed from the sleeve, imparting a rotarymovement to the drill-spindle, thus effecting the advance of the latter. The fourth feature of my invention consists in attaching the differential bevel-gear operating the feedin g-sleeve to the driving-shaft by means of a friction nut or clamp, so that the latter will automatically disconnect itself in the event of a too great resistance to the drill-point, causing the loosening of the bevel-wheel and a diminished progressive movement of the spindle. The lifth feature of my invention consists in providing the feedingsleeve with screw nuts or collars for counteracting or taking up the wear resultin g from the end thrust of the drill and spindle. In the drawing, Figure 1 is a perspective view of the entire diamond drilling-machine. Fig. 2 is a vertical section of the same. Fig. 3 is a top view of the same. Fig. 4 represents a vertical central section of the driving and feeding gear, the pump, clutch mechanism, 820.
The carriage on. which the drill is mounted consists of a wheeled platform or base, on which is arranged a turn-table, A possessing vertical pillars or standards A, which, in connection with transverse beams A applied to their upper ends, constitute supporting-frame. The turn-table A vcarries oscillating engines B, which are intended to be operated either through the medium of steam or compressed air for transmitting motion, through the me-' dium of cranks and connectingrods, to the primary vertical shaft G, which has its bear ings in the movable base A and upper portion of the main frame. Vertical screws Z are provided for securing the drill-carriage in position when, the drill is in operation by causing said screws to bear against the roof and floor of the tunnel or mine. The main or power shaft 0 communicates motion to an intermediate horizontal driving-shaft, D, by means of bevel-gear wheels at b applied to their respective shafts.
Said shaft D and the entire drill mechanism is mounted in a secondary frame, E, which is located within the stationary or main frame A.
.shafts by bevel-gearin g. The adjustable frame E carries also a force or suction pump, P, which is actuated through the medium of connecting rod 0 applied to a crank or wrist-pin on a spurwheel, j, which meshes into a spur-wheel, g, on the primary shaft 0. The gear-wheels a b on said shaft are so connected with the same, by splines and feathers, that they may receive a vertical adjustment corresponding with that of the frame E, thus always preserving their proper positions in relation to each other. A movable head or disk, G, susceptible of being rotated on a horizontal axis, which generally is formed by the horizontal driving-shaft D passing through a tubular extension formedon the head, carries the drilling devices, which are thus enabled to be directed at any desired angle in respect to the walls of the tunnel or shaft. The head G is formed with bearings G G at its opposite ends for the journals cf the drill-spindle or shaft F, which is made tubular and provided with a continuous ex-. ternal screw-thread, as shown. A sleeve, I I, cast or formed with a bevel-gear wheel, h, 1s inserted loosely in the bearing G and through it extends the drill-spindle F, which also passes through the bushing H in the opposite bearing G The gear-wheel h, on the sleeve H, meshes into a corresponding bevel-wheel, i, on the end of the driving-shaft D for imparting a rotary movement to the drill-spindle when the sleeve is connected with the latter by means of a coupling collar or clutch, K. Said clutch surrounds the screw-spindle and is connected with the same by a spline and feather, and with the sleeve H by means of interlocking projections or other suitable devices. The drill-spindle receives a progressive movement when in operation through the medium of a revolving sleeve, I, which is provided with an internal screw-thread corresponding with the thread of the screw-shaft. Said sleeve I carries a bevel-gear wheel, L, arranged concentrically with the drivinggear 70 on the sleeve H, and meshing with a bevel-wheel, M, on the driving-shaft D. The gear-wheel M is held in frictional contact with the wheel 6, and is clamped. against the*face of the same by means of a nut, S, applied to the screw-threaded end of the shaft D, a friction-washer being interposed between the bevel-wheel and nut. The advance of the drill-spindle simultaneously with the rotation of the same is effected by forming the bevel-wheel M with a less number of teeth (one or more) than the sleeve-gear L, while the wheels h t have even-numbered teeth, thus causing the feeding-sleeve to revolve slower than the screw spindle. The drill-spindle carries at its end a diamond point or drill, R, which is usually of a tubular form, so that when in operation it will cut around the circumference of the hole, leaving a core within the bore of the drill, which is extracted when the drill is withdrawn. \Vater is conducted to the drill for washing away the fragments of rock and dust removed by the drill through the tubular spindle and a suitable pipe or hose connected with the pump 1?. The
direction of the drill to its work is determined by the rotating head or disk G, which is capable of being adjusted for boring at any desired angle in a vertical plane, while the neoesssary adjustment for operation in a lateral direction is accomplished by revolving the turn-table A, the desired elevation of the drilling mechanism being in all cases effected by the adjustable frame E. The turn-table is provided with sockets for the insertion of levers for revolving the same, and with clamps O for holding the same in a stationary position. Similar clamps are combined with the revolving head G for the same purpose.
The carriage and the drill mechanism having been properly adjusted, the operation of boring is commenced by imparting a rotary movement to the horizontal shaft D, through the medium of the engines and power-transmitting devices, which will cause the revolution of the sleeve H, and a corresponding movement of the drill-spindle, if the clutch K is connected with the former. Simultaneously with the revolution of the spindle a progressive movement is imparted to the same for feeding it up to its work, as the boring operation progresses, by means of the revolving screwthreaded sleeve I and differential bevel-gearing L M. It the drill should encounter an obstacle of too great hardness to be easily penetrated, the resistance ofi'ered to the drill will cause the nut S on the shaft D to partially disengage itself, thus removing the frictional contact between the bevel-wheels M t, causing the wheel M to slip, and thus diminish the progressive movement of the spindle. The drill is retracted at the end of each stroke for a repetition of the same, by disengaging the clutch or cap K from the sleeve H. For this purpose a collar, screw-threaded, is fixed to the bearing G and receives a screw-cap,W, which is provided with an internal stud or pin, Q, projecting into a continuous circumferentia-l groove in the clutch K. A single turn of the cap disengages the clutch or coupling K from the sleeve H, and the latter from the drill-spindle, thus arresting the rotation of the same. The drill-spindle is now grasped in the hand of the operator for preventing its casuat rotation, and by means of the feedingsleeve I the drill-spindle is withdrawn with the rapidity naturally due to the screw-thread on the spindle.
The .drill may thus be retracted without incurring the loss of the core and endangering the safety of the diamonds, results certain to ensue if the rotation of the drill be not then arrested, When the drill is to be moved up again to its work, it is only necessary to turn the clutch to its normal position for coupling the driving-sleeve to the drill-spindle. ,The feeding gear M is then temporarily unclamped from the driving-gear, and the sleeve held from revolving while the drill is run up to its work, after which the feeding-gear is again clamped to the driving-gear, and the drilling operation repeated. 7
In order to take up the wear resulting from the end thrust of the drill and spindle, I pro vide the feeding-sleeve with a nut or nuts, X Y, encircling and fitted on an exterior thread on the sleeve.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a rock-drill, the arrangement of the sleeves H and I, for imparting a simultaneous rotary and progressive movement to the drillspindle, when the sleeve H is constructed substantially as described, so that the rotation of the spindle can be arrested as the same is re tracted.
2. In a rock-drill, the clutch K and sleeve H, in combination with the drill-spindle F and driving-wheels h 1 substantially as and for the purpose specified. 4 s
, r eases acting the effects of wear, substantially as set forth.
In testimony that I claim the foregoing I have hereunto set my hand this 16th day of December, 1872.
