JOSEPH H. RUSBY, OF NUTLEY, NEW JERSEY.
EXTENSION-DRILL.
Specification of Letters Patent. Application filed September 18, 1909.
Patented Apr. la, i914. Serial No. 518,308.
To all whom it may concern Be it known that I, JosnPi-I H. RUsBY, a citizen of the United States, residing at Nutley, in the county of Essex and State of New Jersey, have invented new and useful Improvements in Extension-Drills, of which the following is a specification.
This invention relates to a drill. The same can be driven by hand or by motor or in any suitable way. The drill is made extensible to a greater or less extent as required for varying kinds of work.
This invention is set forth in the following specication and claim and illustrated in the annexed drawing in which;-
Figure l shows an elevation partly in section of a drill embodying this invention.
ig. 2 is a section along the line a: fr Fig. l.
ig. 3 is a sectional elevation of a modification. Fig. 4c is a section along the line y y Fi 3.
Fn this drawing the letter a indicates a frame which can be of suitable perforated work if desired. A shaft Zi is rotatable in the frame. On the shaft is a rotating piece 0 having a gear connection UZ with shaft e carrying crank arm f with handle or crank g by which rotation can be communicated to the shaft.
The shaft b has a feather connection with the rotating piece so that the shaft and rotating piece will turn together but the shaft can be extended or set in or out as presently explained. In the rotating piece is a latch /z normally engaging the shaft a by means o-f one or another of its stop depressions A spring normally holds the latch to the shaft but said latch can be pressed to releasing position by a pressure on its end which is formed as a thumb button.
When the latch is pressed clear uncoupling the shaft the latter can be set or slid one way or another. A holding handle is shown screwed through the wall of frame a and a breast plate m has a stem inserted into the end of the tubular frame a. By screwing the handle 7c home to clamp or engage the stem or breast plate m the latter is held against pulling out.
A chuck carried by the shaft enables a: tool or drill to be connected to the shaft as required. An externally threaded rotatable adjusting piece n is placed about the shaft. A yoke piece 0 is threaded onto this tubular piece and by means of a chain or connecting means 29 looped about the work (not shown) the drill can be held to contact with the work as the operation of drilling progresses. By suitably rotating or adjusting the tubular piece a slack of the connection p can be taken up as required by the progress of the work, as the rotation of adjusting' piece n will set the yoke 0 to tighten the connection 29.
In the modication shown in Fig. 3 the speed of shaft can be varied. Two gears d are shown both of which are loose on the rotating piece c and one or the other gear can be coupled to turn with the rotating piece o. A coupling slide g can be set back and forth to couple one gear d or the other by lifting the latch r out of one pit and allowing it to snap into another pit of the rotating piece c. Antifriction balls s can be suitably applied to take up the thrust of shaft ZJ during operation. As the gear wheels (Z engage gears placed at different distances from the center of driving shaft e the speed communicated to shaft will be varied.
As shown in the drawing the shaft o may be entirely withdrawn or detached from the frame a and various shafts provided with different types of chuck can be interchangeably employed.
It will be seen that by means of the feathered splineway the shaft will at all times rotate in unison with its driving pinion (Z, and the depressions in the shaft will be maintained in line with the spring latch, so that when a depression z' is opposite the hook portion of the latch the hook will automatically engage a depression and lock the shaft to the gear.
I claim In an extension drill, the combination with a frame, of a shaft rotatably and telescopically mounted in said frame and having a longitudinal series of :dined depres- In testimony whereof I have hereunto set sions, a driving gear mounted 1n the frame my hand 1n the presence of tWo subscribing and a gear driven thereby sphned on sind Witnesses.
shaft, and a retractle spring Catch carried JOSEPH H. RUSBY. 5 by said driven gear and adapted to engage Witnesses:
any one of Said depressions to secure the W. C. HAUFF,
sha-ft n adjusted positions n said frame. CHRIS. OLMSTAEDT.
