Definitions

  • This invention relates to an adjustable machine head of the kind adapted to slide along a horizontal arm.
  • An object of the invention is the provision of a construction in which the head rides freely along the arm to permit a translatory movement of the head during a working operation, or permit moving the head from one operative position to another.
  • the invention also furnishes locking means to hold the head in any desired position along the horizontal arm. This is accomplished by cam-operated means which provide a firm and rigid lock yet can be 5 quickly and easily operated.
  • Fig. 1 is a side elevation of a machine involving the invention.
  • Fig. 2 is a side elevation of a carriage, 30 showing a method of mounting the carriage on the arm.
  • Fig. 3 is a section on line 33, of Fig. 2.
  • Fig. 4 is a section on line 44, of Fig. 2.
  • Fig. 5 is a section corresponding to Fig.
  • Fig. 6 is a fragmentary section taken at right angles to Fig. 5.
  • reference numeral 10 indicates a table or other support which carries the upright housing 11.
  • a post 12 is mounted in the housing in a manner permitting vertical but preventing rotary movement of the post.
  • the post carries a table 13 upon which the horizontal arm 14 is pivoted to permit adjustment in a horizontal plane.
  • the horizontal arm is formed so as to provide an interior trackway for the adjustable 60 head, and comprises an upper wall 15 and depending side walls.
  • the upper part 16 of each side wall descends vertically, the intermediate part slopes outwardly as at 17, while the lower part 18 descends vertically.
  • the lower end of part 18 carries an inwardl directed flange 19, which forms part of the trackway for the adjustable head.
  • the carriage includes a post 23 which extends upwardly between the flanges 19 and connects with an elongated member 24 which has side portions 25 overlying the flanges 19, the upper surfaces of the carriage being sloped as at 25a to conform to the angular portions 17 of the horizontal arm 14.
  • the carriage may be supported in the manner disclosed in the above mentioned parent application, or on small Wheels 34, Figs. 2 and 4, these wheels being mounted on studs and accommodated in recesses 33 in the sides of the carriage.
  • the wheels run on the flange or rail portions 19 of the arm.
  • the principal feature ofthe invention is any operadjustably means for securely and quickly locking the carriage at any point along the horizontal arm.
  • One structure or arrangement for this purpose is shown in Figs. 2 to 4.
  • a plurality of horizontally sliding lugs 36 and 37 project through the side walls of the member 24 for engagement with the walls 18 of the horizontal arm 14.
  • a shaft 38, extending longitudinally of the member 24, has square poretions 39 which rotate cams 40 between lugs 36 and 37 to spread them into engagement with Walls 18.
  • the shaft has at its outward end an operating handle 38a.
  • a plurality of bolts 41 extend through the arm 14 and prevent lateral spreading of the side walls of the arm.
  • a modified locking arrangement is shown in Figs. 5 and 6 in which case the locking lugs 42 slide vertically into engagement with the flanges 19.
  • a shaft 43 is mounted transversely of the member 24 and has cams 44 formed on its ends in cooperative engagement with the lugs 42.
  • An operating shaft 45 runs longitudinally through member 24 at right angles to shaft 43 and has a threaded portion 46 enga ⁇ g gear teeth 47 carried on shaft 43.
  • the Si 45 has an operating handle 45a. In this case rotation of shaft 45 causes cams 44 to depre$ 5 lugs 42, thereby wedging the inclined faces of member 24 into engagement with the inclined side walls 48 of the horizontal arm.
  • the upper rectangular part of the cross arm to ether with the bolts 41, Figs. 2 and 3, may
  • An adjustable machine head structure comprising an arm having spaced side walls with divergent guide-faces and supporting and guiding flanges projecting inwardly below said faces, and a head mounted for longitudinal adjustment within the arm and including outwardly projecting flanges located between said arm guide-faces and flanges, and having angular uide faces cooperating with said arm guideaces and pairs of locking bolts mounted for reciprocation in the head at right angles to the len h thereof, the
  • An adjustable machine head structure comprising an arm having spaced side walls with divergent guide faces and supporting and guiding flanges projecting inwardly below said faces, and a head mounted for longitudinal adjustment within the arm and including outwardly projecting flanges located between said arm guide faces and flanges, and having angular guide faces cooperating with said arm guide-faces and pairs of locking bolts mounted for reciprocation in the head at right angles to the length thereof, the respective pairs being located near opposite ends of the head and the bolts of each pair being arranged for contact of their outer ends with inner faces of the opposite arm side walls, a cam device for sim taneously and directly operating the two bolts of each pair, and a revoluble shaft longitudially mounted in the head and connected to simultaneously and directly operate the cam devices.
