Definitions

  • a primary object of the present invention is to provide a wood working lathe having horizontal ways upon which is slidably mounted a tool rest assembly so constructed as to permit a tool rest, included in the assembly,
  • Fig. 1 is a side elevation of a lathe embodying the concepts of the present invention.
  • Fig. 2 is a section taken along the line 2-2 of Fig. 1.
  • the lathe includes a head end pedestal and a tail end pedestal 11, both of which are suitably secured to a bench or table 12 by bolts 13 or the like. Extending between and supported by the pedestals is a pair of parallel longitudinal tubular ways 14. To the left-hand end of the ways is secured a bracket 16 by screws 17, said bracket being secured to pedestal 10 by fitting over a lock screw '19, the latter being threaded into a boss 20 formed in said pedestal. Screw 19 has a head or knob 21 bearing against pedestal 10, to clamp the bracket against said pedestal.
  • the other or tail ends of ways 14 extend through bosses 22 formed on a bracket 23, to which they are secured by set screws 24 or the like.
  • the lower end of bracket 23 is mounted upon a hinge bolt 25 extending through pedestal 11, this construction permitting the ways 14 and a bracket 23 to be swung (for a purpose of no importance to the present invention) between horizontal and vertical positions when the opposite ends of the ways are released from pedestal 10.
  • Ways 14 can be swung from the horizontal position shown in Fig. 1 until the outer face 27 of bracket 23 engages a supporting arm 28 extending upwardly from the base 29 of tail end pedestal 11.
  • tubular ways 14 are disposed in a vertical position, being held in the latter location by a lock screw or stud 30 which extends into an outer groove or channel 31 in bracket 23, when the latter has been United States Patent 0 disposed against supporting arm 28. Stud 30 is threaded into arm 28, withits tapered head 32 engaging a companion countersunk or tapered portion 33 in groove 31, to lock bracket 23 with the ways 14 disposed in such vertical position.
  • Tubular ways 14 slidably extend through the base 34 of a head stock 35, having a housing 36 at its upper portion receiving a quill (not shown) in which a spindle 38 is rotatably mounted.
  • Spindle 38 is rotated by an electric motor 43, or other suitable prime mover, secured to a mounting place or bracket 44 by bolts 45.
  • Upwardly extending studs 46, threaded into bracket 44, project into the headstock base 34 and are secured in any desired position of adjustment by cap screws 48 threaded into said base against said studs.
  • a stepped driving pulley 49 is secured to the motor shaft 50, transmitting its motion through a belt 51 to a driven stepped pulley 52 slidably keyed to the rear splined portion 53 of the headstock spindle 38.
  • belt 51 can be tightened to the desired extent.
  • Headstock spindle 38 and its supporting quill are movable longitudinally and parallel to ways 14 within housing 36, and may be clampedv in any desired lengthwise position by operation of a clamping mechanism shown and described in detail in my copending application previously identified.
  • the clamping mechanism is actuated by a clamping lever 62, see Fig. l.
  • the quill and the spindle may be moved longitudinally in either direction within housing 36 by the operation of a rack and pinion-type feed mechanism, also shown in my copending application previously identified.
  • a rack and pinion-type feed mechanism is operated by a feed lever 66, see Fig. 1.
  • tailstock secured to bracket 23 by studs 76 and cooperating nuts 77.
  • a spindle 78 extends through the upper portion of the tailstock, and is secured thereto by a nut 79 mounted on the outer threaded end of the spindle.
  • Headstock spindle 38 may have a suitable member mounted on its threaded end (see Fig. 1), such as a face plate or chuck (neither of which is shown).
  • a suitable member mounted on its threaded end (see Fig. 1), such as a face plate or chuck (neither of which is shown).
  • the work is mounted and held between the tailstock and headstock spindles 78, 38 through the manipulation of feed lever 66, which causes movement of spindle 38 toward tailstock 75.
  • clamping lever 62 can be actuated to prevent further axial movement of the quill or the spindle.
  • a tool rest assembly or device mounted on ways 14 is a tool rest assembly or device.
  • said device including a tool rest 80 having depending therefrom a post 81 slidably received by a tool holder 82 and secured thereto in anv desired position by adjusting a clamp screw 83.
  • a rod or post 84 Offset from but parallel to post 81 and depending from holder 82 is a rod or post 84 slidably extending through a boss 85 at one side of a carriage 86, the latter being slidably mounted on tubular ways 14.
  • Post 84 may be moved vertically within the carriage and held in any suitable position by a lock screw 87 threaded into the outer end of the carriage and adapted to bear against post 84.
  • a suitable clamping screw 89 is provided for releasably securing carriage 86 to ways 14 in any position of adjustment of the carriage along the ways.
  • tool rest 80 may be moved toward or away from the work mounted in the lathe by loosening screw 87 and swiveling the work holder to dispose the tool rest in the de sired position. Further, the tool rest may be readily angularly adjusted relative to the work by loosening screw 83 and again tightening the screw after obtaining the desired angular disposition of the tool rest. Upon loosening of either of screws 83 or 87, the tool rest can be adjusted to the desired height for convenient operation. After these adjustments are made, the screw 89 can be loosened to permit the carriage to e longitudinally positioned along the ways. It is an important feature of the present invention that all the tool rest adjustments are accurately maintained even though the tool rest device or assembly is moved longitudinally of the ways. This feature enables many operations to be successfully carried out, such as repetitive pattern cutting operations and the like.
  • the height of the tool rest 80 can be adjusted without any possibility of changing the inward or outward position of the tool rest relative to the work.
  • a woodworking lathe having horizontal ways; a carriage movable along the ways; a tool rest holder mounted on the carriage for rectilinear movement along and pivotal movement about a first vertical axis; a tool rest mounted on the tool rest holder for pivotal movement about a second vertical axis offset from the first vertical axis, whereby the tool rest can be adjusted angularly, vertically and inwardly or outwardly with respect to work mounted in the lathe; and means for releasably securing the tool rest holder against pivotal and vertical movement and the tool rest against pivotal movement, whereby the tool rest can be fixed in any position of adjustment and maintained in such position while the carriage is variously positioned along the ways.
  • a woodworking lathe having horizontal ways; a carriage movable along the ways; a tool rest holder mounted on the carriage for rectilinear movement along and pivotal movement about a first vertical axis; a tool rest mounted on the tool rest holder for rectilinear movement along and pivotal movement about a second vertical axis offset from the first vertical axis, whereby the tool rest can be adjusted angularly, vertically, and inwardly or outwardly with respect to work mounted in the lathe; means for releasably securing the tool rest and the tool rest holder against pivotal and vertical movement, whereby the tool rest can be fixed in any position of adjustment and maintained in such position while the carriage is variously positioned along the ways; and means for releasably securing the carriage to the ways.
  • a carriage movable along said ways; a first vertical shaft mounted on said carriage for rotation on its own axis and for linear movement along its own axis; an outwardly extending arm mounted on the upper end of said first vertical shaft; a second vertical shaft mounted on an end of said arm for rotation on its own axis and for linear movement along its own axis; a tool rest fixed to the upper end of said second vertical shaft; means for securing said carriage to said ways; means for securing said first vertical shaft to said carriage; and means for securing said second vertical shaft to said arm.
