WILLIAM D. MONAULL, OF RONOEVERTE, WVES'I VIRGINIA.
RADIAL-DRILLING MACHINE.
SPECIFICATION forming part of Letters Patent No. 472,546, dated April 12, 1892.
Application filed June 2'7, 1891. Serial No. 397,734. (No model.) I
To all whom it may concern.-
Be it known that 1, WILLIAM D. MCNAULL, residing atRonceverte, in the countyof Greenbrier and State of West Virginia, have invented certain new and useful Improvements in Radial-Drilling Machines, of which the following is a specification, reference being had therein to the accompanying drawings.
This invention relates to drilling-machines.
The object of the invention is to produce a drilling-machine in which the drill may be adjusted to bore at an incline and may be advanced with its support from the main standard and be quickly adjusted and firmly held in working position.
Figure 1 is a broken vertical section of so much of a drilling-machine as is necessary to illustrate my invention. Fig. 2 is a broken elevation and partial section of the upper part of the frame or standard and the drillhead. Fig. 3 is an enlarged front elevation of the face-plate or bracket.
The numeral 1 denotes the base of a drilling-machine or, as commonly called, metalboring drill.
2 denotes an upright standard which supports a bracket or arm 3, on which the bed or boring-table 4 is supported. The bracket and bed are preferably vertically adjustable on the standard by any suitable means, as by rack 5 and pinion 6. The arm 7 passes through a mortise 17 'in the standard 2, so as to have its face-plate 8 above the bed 4, and the plate 8 is preferablyadisk, which may have curved slots 9 9 therein. 7
The drill-head 10 has a plate 11, which fits against the plate 8 and is preferably countersunk to receive said plate. The plate 11 may be turned on the plate 8 and secured in any adjusted position by bolts passing through holes in said plate 11 and through the slot 9 in plate 8, the bolts having nuts 13.
The edge of the plate 11 is preferably graduated, so that the head may be readily adjusted to any angle and the angle indicated. It is manifest that the position of the slots and bolts is not important, and any other suitable clamping mechanism'by which the drill-head plate may be held when adjusted 011 the bracket will answer the purpose of the slots and bolts and nuts; also that it is immaterial which of the plates 8 and 11 embraces the other. By inclosing a disk face-plate on one member in a recessin the other member, however, the strains are taken off from the fastening devices, as it would not be if two faceplates were simply clamped together face to face, as is common.
An arm or guide 15 projects radially from the swivel-plate 11 and may be integral therewith or firmly secured thereto. The guidearm 15 can thus be adjusted to various angles in a circular plane, the center of which is the center of plate 8.
The driving-shaft extends lengthwise through the hollow arm 7. Shaft 20 may be driven by means of a bevel-gear 21, engaging a bevel-gear on a counter-shaft supported on standard 2, arm 7 being slotted to admit the engagement of such driving-gear, or the'shaft 20 may be driven by other suitable driving means. 7 I
The arm 7 is adjustable through the mortise 17, as by means of rack 23 on the arm, and pinion 24:, supported on the standard and engaging said rack on arm, or the arm may be adjusted with screw and hand wheel or crank.
p The arm 7 is held from rotation in the mortise in the machine illustrated by the rack 23, fitting closely in a slot or recess at one side of the mortise 17.
Shaft 20 passes through the face-plates 8 and 11 and has a bearing 80, attached to the plate 8 and preferably extending through a hole in the plate 11. A bevel-gear on the gear 31 on the drill-shaft or boring-bar.
A bracket 25 extends from the lower end of arm 15 and is perforated to form a guideway for the drill-rod sleeve 33. Abracket 27 extends from the upper end of plate 11 and forms a bearing from the hub 32 or bevelgear 31 in line with the guide-bracket 25.
The drill-rod or boringshaft 35 passes through the sleeve 33 and the driving-gear 31 and is splined or otherwise constructed in usual manner to be free to move lengthwise through the. driving-gear, but to turn with the gear. Thus the rotation of shaft 20 causes the drill-shaft to rotate at Whatever angle it may be held by the brackets 25 and 27.
The face-plate 11 and arm 15 form the drillcarrier, and also carry supporting-brackets end of. said shaft is in position to engage a 28 and 29, in which the counter-shaft 40 has its bearings, said shaft extending parallel with the drill-rod, or nearly so. The shaft 40 has driving-pulleys ll attached thereto and the drill-rod or gear 31 carries a corresponding set of pulleys 36, which pulleys rotate with the drill-rod. Thus by belting from pulley 36 to pulley 41 the counter-shaft 40 may be driven.
iSihaft 40 has a bevel-gear42,-which engages a similar gear 43 on a transverse worm-shaft t-l. Said shaft 44: is supported in suitable bearings near the lower end of bar 15. A worm t6 on shaft M engages a worm-gear 4-7 on shaft 48, which shaft extends in proximity to the sleeve Shaft 48 carries a pinion 49, which engages a rack 50, fixed to one side of sleeve By this train of gearing the sleeve can be caused to raise or lower the drill-rod 35 and feed the drill to its work or raise it from the same, the drill-rod being free to turn in the sleeve 33, but made to move lengthwise with said sleeve by a collar or similar engagement, as usual in machines of this class.
The shaft 18 and pinion 49 can be thrown out of engagement byaclutch 51, so that the worm l6 will not drive pinion 4:9), and thus stop the feeding of the drill. By hand wheel or lever Set 011 the end of shaft T8 the drillshaft may be moved independently of the wornrgear when said gear is out of engagement.
It is apparentthat the location of the clutch is not material. It can be at any convenient place to throw the train of feeding-gears into or out of operation.
The shaft 44 and worm 46 may be actuated by the hand-wheel 52 to feed the drill-sleeve forward.
Numerous modifications in the construction will suggest themselves. The important feature of the invention is the radial adjustment of the drill-bar and its guiding and feeding mechanism without interfering with the driving connection between the drill-rod and the main driving-shaft.
What I claim is- 1. In adrillirig-machine, a vertical standard having a transverse mortise and a drivingshaft carried by said standard, an extensible transverse non-rotatable bracket or arm pass ing through said mortise,a drill-carrier radially adjustable on said arm, and a drivingshaft carried by the extensible arm and having gears engaging the driving-gear of the main standard and the driving-gear of the drill-spindle in all positions of the bracket or arm, all combined substantially as described.
2. In a drilling-machine, the combination of the vertical standard having a transverse mortise near the top, a driving-shaft, the extensible non-rotatable hollow arm passing through the mortise and having a radially-adjustable drill-carrier at its outer end, the shaft in said arm having gears engaging the drilldriving gears and a gear on the main shaft in all positions of the arm, and a rack on said arm engaging a pinion carried by the main standard, whereby the arm may be extended or withdrawn and the driving-gear maintained in constant engagement, substantially as described.
3. The combination, with the standard havingatransverse mortiseandadriving-shaft, an extensiblenon-rotatable arm passingthrough said mortise, a faceplate at the outer end of said arm, a drill-carrier radially adjustable on said faceplate, a driving-shaft extending through and adjustable with the extensible arm, and gears on said shaft engaging gears 011 the main driving-shaft and on the drillearrier, substantially as described.
4-. The standard and extensible non-rotatable arm having a circular face-plate, the drillcarrier having a circular recess to receive said faee-plate, clamping mechanism to retain said drill-carrier in radial adjustment on the arm, and the driving shafts and gears carried by the arm and drill-carrier, all in combination substantially as described.
5. The eombinatiomwith the uprightstandard having a transx'erse mortise, the extensible non-rotatable arm passing through said mortise, the circular face-plate at' the end of said arm, the drill-carrier having a recess which receives said face-plate, and clampingbolts passing through the carrier and through slots in the face-plate, all substantially as described.
In testimony whereof I atlix my signature in presence of two witnesses.
