  • the main shaft or spindle of the drilling machine is provided in accordance with my invention with an intermediate spindle or 'shaft e which may be mounted thereon by conical fitting or the like.
  • This intermediate spindle e of suitable material carries at its free extremity the drill or borer h.
  • a sleeve or collar a is slidingly disposed which is provided at each end thereof with a ball bearying b.
  • An outer sleeve or bearing casing c encloses the sleeve'a and the bearings andv is adapted to connect the ball bearings to each other and carries at one of its lower ends a detachable funnel shaped chip receptacle f which surroundsthe drill h and is rovidedv at its frontend with the detac able ⁇ exchangeable centering collar or bushing4 g.
  • the diameter of the bore of this collar g is larger than that ofthe drill, so as 'to prevent contact thereof with the 'inner'walll ofthe collar and'allow the chips to freelyprass up into the receptacle f.
  • the cover d isf provided at the other, upper end of the'sleeves a and c and constitutes a closing cap for the device, and it is provided with any suitablen suspending or supporting or locking device.
  • Such supporting, locking and releasing means are shown by way of exempliiication in F ig. 2 of the drawing.
  • the entire device is suspended or supported in any suitable manner, as indicated at p, and carries a collar or head Z upon which the spring- Aactuated levers ⁇ or gripping claws m are pivoted at o the free and preferably in- ,yvardlydirected' .or hook-shaped ends of whichare'adapted to become engaged with therecesses s of the cover d.
  • the grippers ⁇ m areiinder the action of the springs n and may be manually operated by pressure upon their outer ends t, so as to engage with or release the cover d and thereby the entire system of collars and sleeves.
  • the mode of operation of the device is substantially as follows
  • the stencil sheet z' carries the drilling apertures.
  • the entire desleeve g is introduced into the particular hole of the stencil plate z'.
  • the drill shaft may be advanced into the operative positionwith its intermediate spindle e and the spiral drill It.
  • the system -a is again raised by being, for instance, suspended from the spring-actuating hooks m, whilethe drill is now freely exposed and centered and the chips are thereby readily discharged.
  • the releasing and suspension device which is connected to the main spindle is free to rotate with the same.
  • the intermediate spindle e is of such a size that different conical iittings may be employed for connecting the same to themain spindle or to the drill.
  • the collar g may be outwardly conical.
  • a rotatable spindle Ina boring or drilling tool, a rotatable spindle, a drill bit carried by the spindle, a housing slidably mounted on the spindle and in which the spindle is rotatably mounted, a chip receptacle detachably connected with the lower end of the housing, and a centering bushing at the outer end ot said receptacle through which the drill bit projects, the bore of said bushing being of greater diameter than the bit for the free feed of the chips upwardly between the bit and bushing and into said receptacle.
  • a rotatable spindle a sleeve slidably engaging the spindle and in which said spindle is rotatably mounted, a housing enclosing the sleeve, anti-friction bearings interposed between the sleeve and housing above and below the horizontal center of the housing, a drill bit carried by the spindle, a chip receptacle detachably connected with the housing, and a centering bushing connected with the outer end of the receptacle, through which receptacle and bushing the drill bit extends, the bore ot the bushing being of greater diameter than the bitfor the free passage of the chips between the same and the bit and upwardly into said receptacle.
  • a rotary spindle In a boring or drilling device, a rotary spindle, a housing slidably engaging the spindle and in which the spindle is revolubly mounted, a conical chip receptacle detachably connected with the outer end-of the housing, a drill bit carried by the spindle and extending through the housing, and a conical centering bushing detachably engag ing the outer reduced end of the receptacle and through which the drill bit extends, the bore of said bushing being of greater diameter than the drill bit to permit the chips to pass upwardly'between the same and into the receptacle.
  • a rotary spindle In a boring or drilling device, a rotary spindle, a suspending device carried by the spindle, a collar caried by the spindle, a housing slidably mounted on the spindle for movement toward and from said collar and in which housing the spindle is rotatably mounted, a chip collecting chamber detachably connected with the lower end of the housing, and provided at its outer end with a centering bushing, a drill bit carried by the spindle and extending outwardly through the chamber and bushing, a closure at the top of the housing provided with an annularly grooved head, and spring fastening members on the collar engageable with the annular groove of the closure when the housing is slid u wardly on the spindle.
