' SPECIFICATION forming part of Letters Patent No. 543,395, dated July 23, 1895.
Application filed November 1. 1894. Serial No. 527,663. (No model.)
To all whom it may concern.-
Be it known that I, ANTON MILL, a citizen of the United States of America, residing at Cincinnati, in the county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Drilling, Boring, and Turning Machines, of which the following is a specification.
The object ofmy invention is, first, to combine with a vertical drilling-machine mechanism for truing, turning, and like work; secnd, to provide a compact and efficient machine for all kinds of drilling, boring, and turning; third, to provide simple and etficient means whereby the movable parts may be manipulated manually or mechanically; fourth, to provide an arrangement of clutches where- I by the movable parts may be operated simultaneously or individually, and, fifth, in an arrangement and connection of the parts whereby the relative speed and direction of movement of each may be governed.
My invention consists in the mechanism andcombination and arrangement of mechanism hereinafter described and claimed.
In the drawings, Figure 1 is a side elevation of my machine; Fig. 2, an end elevation; Fig. 3, a partial end elevation showing a modificdform of feeding mechanism; Fig. 4, an en-' larged transverse section of a part of the machine online 4: 4 of Fig. 1; Fig. 5, an enlarged longitudinal section of the upper drivin shaft; Fig. 6, an enlarged section of a portion of the modified feeding mechanism; Fig. '7, a plan of the same; Fig. 8, a conventional elevation of the tapering mechanism; Fig. 9, an enlarged view of the shaft carrying the back gears; Fig. 10, a detail view; Fig. 11, asection of Fig. 10; Fig. 12, a detail section; Fig. 13, a descriptive view. 7
A represents the main frame; B, a shaft adapted to be connected to a source of power;
G, a driving-shaft adapted to be belted to the shaft B and which drives a drill-spindle D.
G is a secondary frame, adapted to move relatively to the main frame and carryingthe feeding mechanism, the lower end of the drillspindle, and a traveling tool-carriage H.
I is a shaft driven from shaft O, adapted to drive the feeding mechanism; K, an arbor adapted through connecting mechanism to raise or lower the secondary frame-relatively tothe main frame; J,an arboradapted through connecting mechanism to raise or lower the drill-spindle relatively to the secondary frame; L, a frame adapted to swing on the lower part of the main frame, carrying a revoluble faceplate M; N, a movable shaft driven from shaft 0 and by connecting-gearing adapted torotate face-plate M.
The main frame of the'machine consists of a base a, a main column a, and a secondary column a The lower extremity of the secondary column a is divided to form a fork adapted to support the shaft B, which carries a driving-pulley b and a speed-pulley b. A curved arm a extends from the column a, and carries a bearing a. On the opposite side of the column a is an arm supporting a hearing a in line with bearings of. Mounted in these hearings a a is a driving-shaft O,
upon which is loosely mounted a sleeve 0,
having secured thereto a speed-pulley c in line with the speed-pulley b. The endjof sleeve 0 nearest bearing a is provided with cluteh-teeth 0 adapted to be engaged bya clutch c feathered to the shaft 0, and capasupported in a sleeve 0 carried by the bearing a and provided at its outer extremity with a beveled pinion 0 The inner end is provided with a series of teeth adapted to be engaged by a clutch e feathered to shaft O. Bevel-pinion 0 is adapted to engage with a corresponding pinion d, supported on a hearing a andfeathered to the drill-spindle D.
Mounted in eccentric rings 6 in standards a is a shaft E, adapted to be actuated by lever e and carrying gears e e adapted to mesh with gears c 0 By partially rotating the eccentric-rings the gears c 6 may be thrown in or out of engagement with gears 0 0 When the clutch c is in engagement with sleeve 0 the speed-pulley c' and shaft 0 will rotate together. When clutch c is disengaged from sleeve 0 the sleeve is free to rotate on the shaft. By throwing the gears e a into engagement with gears c c the speed of the shaft, relatively to the speed of the sleeve, will be varied in accordance with the arrangement of the differential gearings e e c 0 The drill-spindle D passes through bearing (1 and its lower end is journaled in a sleeve F carried bythe secondary frame G and movable relatively thereto. The sleeve F is provided with a rack-barf, which engages with a pinion j, secured to an arbor J, mounted in suitable bearings on the secondary frame. By revolving the arbor the rack-bar is made to travel on the pinion j, and the sleeve F is raised or lowered. Loosely mounted on the arbor J is a gearj secured to a worm-wheel 7' also loosely mounted on arbor J, and provided on its outer side with clutch-teeth j. livotally secured to the outer end of arbor J is a leverj provided at one end with clutchteeth j, adapted to engage with clutch-teeth j. The opposite end is provided with an operating-handlef. By moving the handle toward the secondary frame the clutch-teeth 3' are disengaged from clutch-teeth 7' and the arbor J and worm-wheel j are free to rotate independently of each other, but when the teeth are in engagement the two rotate together. An arbor K passes through suitable bearings in the secondary frame, adjacent to the main column a, and carries a pinion 7c adapted to engage with a rack-bar a secured to the column a. By rotating the arbor K the pinion 7a is made to travel on the rack-bar, and the secondary frame is raised or lowered on the main column. The outer end of the arbor is provided with a friction-clutch adapted to engage with a gear 70 loosely mounted on the arbor K and in line with the gear 7 By throwing the clutch 70' into engagement with the gear 70 the two will rotate together, but are free to rotate independently of each other when the clutch is disengaged. Gears g are mounted on an arm 9, pivotally secured to the secondary frame and adapted to connect gearsj and 70 By mounting the gears g on a pivoted arm it is possible to throw them into a position such that they connect with gears 7' and 70 or to throw them into a position out of engagement with these gears. The arbor K may thus be operated from arbor J, if required, or may be operated independently. A clamping-bolt 9 passes through a slot in the arm gand into the secondary frame and holds the arm in any required position.
Mounted in a bracket 0, secured to the main frame, is a shaft 0, carrying a speed pulley 0', in line with the speed-pulley c and a bevel-pinion 0 adapted to mesh with bevelpinions t t", loosely mounted on shaft I, one above and one below the axis of shaft 0. The shaft I passes through suitable hearings in the bracket 0. A clutch d is feathered to theshaft I between the bevel-pinions 2' 2' and is adapted to engage with teeth on the inner faces of the bevel-pinions. When the clutch is moved longitudinally on the shaft I, so as to engage with the bevel-gear 2', the shaft Z will be rotated in one direction by rotating the shaft 0, and by throwing the clutch into engagement with the bevel-pinion 2' the shaft I will be rotated in the opposite direction. Alever o is connected with the clutch t by means of the ordinary loose yoke. The lower end of the shaft I is provided with a bevel-pinion i adapted to engage with a similar pinion p, loosely mounted on a shaft 1', provided with a worm p, adapted to engage with worm-wheelj The outer end of shaft P is provided with a hand-wheel Q33. The hub of pinion p is provided with clutch-teeth 19, adapted to engage with clutch 19 secured to the shaft P. By disengaging the clutch from-the bevel-gear the shaft andbevel-pinion are free to rotate independently of each other, but will rotate together when the clutch is in engagement with the beveled pinion. By rotating shaft I shaft P will be rotated, and through worm p worm-wheel j will be rotated. If clutch-teethj are in engagement with clutch j the arbor J will rotate with the worm-wheel, and the sleeve F may be lowered or raised relatively to the secondary frame G by means of pinionjand rack-bar f. The speed-pulley 0' is belted to speed-pulley c and by rotating shaft 0 the spindle D may be raised or lowered, as the case may require. If gears g are thrown into engagement with gears j and 70 the arbor K may be rotated from shaft 0 and the'secondaryframe raised or lowered on the main column, as the case may be. By throwing the clutch-teeth 3' out of engagement with clutch-teeth 7' the sec ondary frame will be raised or lowered without moving the spindle relatively thereto.
Secured to the secondary frame G are Ways g adapted to support the traveling tool-carriage H. A T-slot h in the tool-carriage is adapted to support a tool-post and cuttingtool. A screw it, parallel with the ways, supports a nut k secured to the traveling toolcarriage. The outer end of screws 7?. is provided with a gear h Rigidly secured toshaft P is a spiral gear 19 adapted to engage with a spiral gear h, secured to a shaft 71 parallel with screw 7t. The opposite end of shaft h is provided with a gear h, adapted to engage with gear 72. By rotating the shaft P power will be transmitted through the spiral gears, shaft 71 and gears h 7L3 to screw h, and the carriage II moved along the ways by means of the nut 72 For turning an inclined surface I provide mechanism consisting of an angular guide Q, pivotally mounted in a bracket a secured to the main frame, a lever 9 pivotally mounted in a bracket g secured to the secondary frame G and slotted link 9 pivotally secured to one arm of lever g and adapted to be clamped to the traveling tool-carriage H by means of a bolt h The opposite end of lever q carries a roller 9, adapted to travel in the angular guide Q. Aslotted are a is secured to bracket a and carries a series of graduations. The upper end of guide Q, is provided with an index adapted to register with these graduations. The guide may be tilted at any required angle and locked in position by means of a clamp-bearing a.
To feed the secondary frame downward and the tool-carriage at right angles thereto the nut h2 is removed from the tool-carriage H and the link clamped thereto. The machine is started, and, by the mechanism hereinbefore described, the secondary frame is moved relatively to the main frame, the lever 9 moves with the secondary frame, and the roller g follows'the angular guide, and the lever is moved on its pivot, thus sliding the tool-carriage on the ways. The faceplate M is pivoted on the frame L and is provided with a gear m on its under face, adapted to mesh I with a gear a, mounted on the main column. The shaft N is mounted in a movable bear-' ing a and carries a bevel-gear n, adapted to mesh with bevel-pinion c and a gear n onits lower end, adapted to mesh with gear a.
l By revolving shaft'O power istransmitted to the face-plate through the gearing and shaft N. By lowering the bearing a. the bevelgear at will be disengaged from bevel-pinion c and the shaft 0 may be rotated without rotatingthe face-plate.
To clamp the face-plate into a position concentric with the axis of the spindle I provide a bracket Z, extending from the frame L, having an aperture adapted to register with an aperture in the base of the main frame when the face-plate is concentric with the spindle. A bolt or pin Z passes through these apertures and prevents the frame from moving.
To explain the operation, assume that a pulley is to be drilled, bored, turned, and crowned. The pulley is clamped to the face-. plate and a drill placed in the spindle D. The
shaft N is lowered and the pinion n disengaged from c. The clutch 0 is thrown into engagement with the sleeve 0 and the machine started. The spindle D will be revolved, and, by manipulating the feeding mechanism as described, the drill may be fed downward while rotating and the shaft-hole of the pulley drilled. If it is necessary to make a large shaft-hole, a boring-tool may be clamped either in the spindle or tool-carriage, the clutch c disengaged from sleeve 0 the shaft N raised until bevel-pinion n engages bored to the required size.
bevel-pinion c and the machine is started.
The spindle does not rotate, but the face-plate a reverse direction.
the clamping-bolt h tightenedlupon the link 9 The gears g are thrown into a position so as to connect gears 7' and 10 the frictionclutch is is closed, and the machine started. The face-plate will rotate, the secondary frame fed downward and the tool-carriage slightly moved at right angles to the path of -movement of the secondary frame, and the face of the pulley turned at the required angle, thus crowning the pulley-face. By throwing the clutch 11 into engagement with the beveled pinion (not used in these described operations) the movable parts will be fed in When it is necessary to drill big Work, the frame L may be swung on column a and the face-plate .removed from beneath the spindle.
In Figs. 3, 6, and 7 amodifiedform of feed-- ing mechanism is shown. The speed-pulleys c .0, shaft I, and gearing o I I are supplemented by a gear 01, secured to the beveled gear d, a vertical shaft R passing through a suitable bearing on the main frame and having a gear r feathered thereto adapted to mesh with gear d. The lower end of the shaft carries a crown-wheel 0", having several series of cog-teeth r at difierent radial dis tances from the center of shaft R. Mounted in suitable bearings, at right angles to the shaft R, 'is a shaft S, carrying at its free end. a. bevel-pinion 8, adapted to engage with a bevel-pinion s, mounted on a shaft corre sponding to the lower end of the shaft. I. A gear 3 is feathered to the shaft S beneath the crown-wheel. A forked arm 8 takes around the gear 3 and is adapted to slide the gear along the shaft and hold it inengagement with any required series of teeth on the crownwheel 1". The speed of the shaft S, relatively to the speed of shaft R, will be varied according as the gear 5 is in engagement with a series of crown-teeth nearer to or farther from the center of shaft R.
