GEORGE H. EVERSON, OF PITTSBURG, PENNSYLVANIA.
MACHINE FOR DRILLING 'RIVET-HOLES IN WHEEL-HUBS.
SPECIFIGATION forming part of Letters Patent No. 706,811, dated August 12, 1902.
Application filed m 18,1901.
To all 111710117, it may concern:
Be it known that I, GEORGE H. EVERSON, a citizen of the United States, residingat Pittsburg, in dhe county of Allegheny and Stateof Pennsylvania, have invented certain new and useful Improvements in Machines for Drilling RivetHoles in WVheel-Ilubs, of which thefollowing is a specification, reference being had therein to the accompanying drawings.
This invention relates to machines for driIl-. ing rivet-holes in metallic hubs, and has par-, ticular reference to a machine adapted for, use in the manufacture of the improved wheel shown in my application for Letters Patent filed April 19, 1901, Serial No. 56,575.
The primary object of the invention is to provide a multiple drilling-machine which may be readily adjusted for operating on hubs of different sizes and with which all of the rivet-holes are drilled by a single operation.
A further object is to provide a double machine wherein the alternate drills operate and are fed in reverse directions, whereby the hub being operated upon is held by the drills themselves, working in opposing relation, against lateral displacement.
Still a further object is toprovide improved adjustable mechanism for sustaining wheels of different sizes. I
The invention consists in the novel features of construction and in the combination and arrangement of parts hereinafter fully described and claimed, and illustrated by the accompanying drawings, wherein Figure 1 is a View, partly in elevation and partly in vertical section, of a machine constructed in accordance with my invention. Fig. 2 is a vertical cross-sectional view on line 2 2 of Fig.1. Fig. 3-is an elevation of the wheel-holding mechanism.
As the machine is double, with both portions thereof identical in-construction for the purpose of drilling adjacent holes simultaneouslyin opposite directions, the following description applies to either portion of the machine.
Referring to the drawings, 2 represents the bed-plate, having the longitudinal ways 3, upon which is adapted to travel the carriage 4. For feeding the carriage longitudinally a rack 5 is secured to the under side thereof,
slots with guideways 12. .in.theseguideways are the yoke-shaped heads Serial No. 68,904.. (No model) the separated supports 9, and secured therein are the separated circular frames 10, which are united at their peripheries by heads 11.
just described the diameter of the circle of v drills may be increased or diminished, as required.
At the rear end of carriage 4: is the vertical bifu rcatedpost 19,"andjournaled therein is a circular series .of pinions 20, from which project the flexible shafts 21, which connect with the several drill-chucks 17; All of pinions 2O mesh'with the centrally-arranged gear 22, having an elongated spline connection with the fixed drive-shafts25, whereby carriage 4 may be adjusted longitudinally ofthe driveshaft without aifectingthe operation of the mechanism. The flexible shafts 21 permit the drill-chucks to be adjusted radially, as described, without affecting their operation.
Prior to drilling the rivet-holes with my improved mechanism-the wheel, including its hub 24:, spokes 25, and rim 26, is fully assembled, and the wheel isseeured within one portion of a double upright frame 27 This frame is movable transversely of the 'machine, with its base 28 resting on rollers 29, projecting from adjacent ends of beds 2. The wheel is placed in upright position in a cradle 30, provided on its under side with a screw 31 and vertical guides 32, and operating on this screw to raise or lower the cradle for holding the wheel in the desired elevation is feed wheel or nut 33. A clamp 34, having stem Movable radially IOO 35, is vertically adjustable in the upper portion of frame 27 for engaging and confining the upper portion of the wheel. With the frame 27 double, as described, one wheel may be operated upon while a wheel previously operated upon is being removed and a fresh one inserted, thereby keeping the machine in practically continuous operation.
With the several adjustments above described the wheel may be positioned and its hub accurately centered in the machine with great facility, and when in proper position the opposing sets of drills are set in motion and operated to drill adjacent rivet-holes 36 in opposite directions in the continuous peripheral flange 24' of hub 24, which contains the spoke-sockets. With the spokes in position the latter are drilled at the same time, so that when the wheel is removed from the machineitis all ready to receive the rivets which confine the spokes in the hub. As adjacent drills operate in opposing relation, it is only necessary to provide a vertical support for the wheel, as the drills by their own action serve to hold the wheel against lateral displacement. With the drills radially adjustable, as described, and with the wheel-holding mechanism capable of expansion and contraction it will be apparent that the machine may be readily adjusted for operating on wheels of various sizes.
Having thus fully described my invention, what I claim as new, and desire to secure by Letters Patent, is-
1. In a drilling-machine, the combination of separated parallel side members formed on adjacent faces with corresponding radial guideways and radial slots, heads slidable in the guideways, drill-actuating shafts extending through said radial slots and journaled in said heads, shaft-actuating means, and means for radially adjusting said heads, substantially as shown and described.
2. In a drilling-machine, the combination of drilling mechanism, an upright work-holding frame, wheel-supporting cradle 30, screw 31 and guides 32 depending from the cradle into the lower portion of the frame, means for vertically adjusting said screw, and an adjustable wheel-clamping device in the upper portion of the frame, substantially as shown and described.
In testimony whereof I affix my signature in presence of two witnesses.
