MAQHINE FOR DRILLING SPOKE-HOLES IN METALLIC WHEEL-FELLIES.
SPEQIFICATION forming part of Letters Patent No. 701,694, dated June 3, 1902.
Application filed May 20, 1901.
To @ZZ 'wtom/ it puny concern:
Be it known that I, GEORGE H. EVERsoN, a citizen of the United States, residing at Pittsburg, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Machines for Drilling Spoke-Holes in Metallic Wheel-Fellies, of which the following is a specification, reference being had therein to the'accompa-v` nying drawings.
This invention relates to a machine for drilling spoke-holes in wheel rims orfellies; and the primary object thereof is to provide an improved machine of the typel having a radial series of drills adapted to operate simultaneously and form all the spoke-holes at one and the Sametime. i r 1 y The invention consistsin'the novel features of construction and inthe combination and arrangement of parts hereinafter described and claimed, and illustrated by the accompanying drawings, wherein- I Figure 1 is avertical sectional view of'rny improved machine; and Fig` 2`is a` top plan; view of the same, portions thereof 'being broken away to illustrate underlying mechanisms. Fig. 3 is a detail view illustrating the adjustment of one of the ,work-holding devices. Fig. 4" is a sectional view of thev spindle-feeding wedge.
Referring to the drawings, 2 represents a dome-shaped bed-plate having at its top the hollow bearing 3, and fitting within this bearing is the depending and` hollow projectionVv 4 of the top frame portion 5. YSecured to'and extending radially outward from frame 5 are the horizontal ribs or bars 6, slotted longitudinally at 7 and at their outer ends supported on the upper ends of standards 8, rising from base 2. Formed inthe upper face of frame 5 is a series of radially-arranged depressions 9, and confined therein by cap-plate 10 are the siidingheads 11, formed, preferably, of brass. 12 denotes the longitudinally-movable drillspindles, journaled at their inner ends in heads 11, with their outer portions journaled in bearings 13 on plate 5. The spindles are heldnormally retracted by springs 14, which embrace the same in front of a ring 15', shrunk on each spindle, the springs being preferablyy secured by bolts 10', which hold cap-plate 10 in place.
'Serial No. 61,166. (No model.)
For feeding the spindles forward against the pressure of springs 14 I provide a downwardly-tapering wedge 19, which is substantially circular in cross-section and provided ,with the radial ribs l19', which fit correspondling depressions 11 in the inner inclined faces -of sliding heads 11. Wedge 19 is secured to the upper end of shaft 20, which extends downward centrally through the machine and into tubular bearing 2 1, rising from the base of bed-plate 2. Rotatably mounted on bearing 21 is the horizontal gear-wheel 22, having a threaded bore through which extends the `threaded portion of shaft 20, and meshing .with gear 22 is pinion 230m the inner end of feed-regulatin g shaft 24.' This shaft may be actuated in any suitable manner, and-by means vthereof and of thev interposed gearing shaft `20 and wedge 19V are moved as required for sliding all of heads 11 simultaneously, thereby feeding the drills forward uniformly and at the required speed. y After the drilling has been completed the movement of shaft 20 is reversed, thereby raising wedge 19, when springs 14 retract thel spindles automatically, thus disengaging the drills from the work.
For sustaining fellies of different diameters in operative position on the machine I provide a series of supports 26, which rest on the radial bars 6, withk the vertical member 27 of each support formed with a bushed opening 28, which forms an accurate guide for passing the drill 29 to the work. Supports 26 are slidable longitudinally on bars 6, and depending from each support through IOO slot 7 is projection 30, formed with a threaded aperture, and extending through the latter is the screw-shaft 3l, which is parallel with bar 6. This shaft is sustained in a bearing 32 at the upper end of standard S and is provided at its outer extremity with wrenchhold 31. At the inner end of the shaft is pinion 33, which meshes with the large gearwheel 34, the latter encircling the upper of bed-plate 2 and supported thereon by ballbearing 35. All of the radially-extending shafts 31 are thus geared together, so that rotation of any one thereof by means of a wrench applied to its outer end will simultaneously rotate all of said shafts, and thus move supports 26 uniformly either inward or outward, as may be required.
The top surface of each of supports 26 is preferably inclined and formed with a dovetailed guideway 36 to receive corresponding projection 37 on the under side of the adjustable rest 38. The under surface of this rest is inclined complementary with surface 36, but the top thereof is constantly level. By this means the supports may be adapted to receive either wide or narrow fellies and accurately center them with regard to openings 28. A further adjustment in this regard may be had by providing each of rests 38 with a removable top plate 39, which may be used or not, as circumstances may require. For adjusting rest 3S the same may be provided with a bottom projection 40, having the screw 41 extending therethrough, the screw being journaled in support 26.
The machine here shown and described is constructed with special reference to drilling the spoke-holes of the U-shaped metallic rims shown in my application for patent on metallic wheels filed April 19, 1901, Serial No. 56,575. In this form of felly the metal to be bored is comparatively thin, and for this reason a hollow drill is preferably used. It will be understood,- however, that the invention is not limited in this regard, as fellies of different forms and of varying thicknesses may be drilled with equal facility.
Vith the telly-supports 2G properly adjusted and the felly positioned thereon the drills are very accurately centered in passing through the bushed openings 2S, and hence the spoke-openings are formed at corresponding points and with the greatest possible precision.
The machine here shown is provided with eight spindles for drilling as many holes simultaneously. In my above-recited application the wheel shown is provided with sixteen spokes, and for drilling the felly thereof on an eight-spindle machine eight holes are first drilled, and then the felly is so turned as to drill the other eight holes midway between those Iirstdrilled. It will be understood, however,that the machine may be constructed with a greater or less number of spindles, as may be desired.
Having thus fully described myinvention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a drilling-machine, the combination of a frame,a circular series of heads 1l slidable` horizontally therein and formed with inclined inner ends, a tapering device movable vertically and centrally through the series of slides and adapted to impinge the inclined innerend surfaces thereof, a drill-chuck rotatably mounted in each slide, and means for rotating the chucks, substantially as shown and described.
2. In a drilling-machine, the combination of an elevated bed-plate, drills and drill rotating and feeding mechanism supported at the upper end thereof, standards 8 positioned outwardly from the bedplate, horizontal screw-shafts 31 journaled at their outer ends in said standards and at their inner ends provided with pinions, a bearing encircling the upper portion of the bed-plate, a large gearwheel sustained by said bearing and meshing with said screw-shaft pinions, and worksupportiug devices in engagement with and adapted to be adjusted by said screw-shafts, substantially as shown and described.
3. In a drilling-machine, the combination of a bed-plate having the upwardly-projecting tubular bearing 3, top frame portion 5 having the depending part 4 fitting bearing 3, drill-chucks rotatable in the frame portion 5, a pinion on each chuck, alarge gear-wheel mounted on bearing 3 and meshing with all of said pinions, and means for driving said gear, substantially as shown and described.
In testimony whereof I ailix my signature in presence of two witnesses.
GEORGE Il. EVERSON.
