Definitions

  • ABSTRACT Apparatus consists of a differentially threaded sleeve surrounding and in threaded engagement with an adjustment rod which in turn is connected with an axially adjustable side trimmer knife-mounting in a side trimmer housing.
  • An elongated nut which is restrained from axial movement, is circumferentially mounted around the sleeve in threaded engagement therewith. Means are provided for selectively restraining the sleeve from axial movement relative to the adjustment rod during rotation of the sleeve.
  • FIG 5 AIPARATUS FOR ADJUSTMENT OF SIDE TRIMMER KNIFE BACKGROUND OF THE INVENTION
  • the invention relates generally to side trimmers and more particularly to an improved apparatus for axially adjusting one side trimmer knife relative to another.
  • the primary object of our invention to provide an improved apparatus for easily and quickly making adjustments of side trimmer knives during operation of a side trimmer.
  • apparatus as set forth in the above object which includes an adjustment rod connected with the mounting structure of a side trimmer knife in a side trimmer housing, a differentially internally and externally threaded sleeve rotatably disposed around the adjustment rod in threaded engagement therewith, means for rotating the sleeve, a nut fixed against axial movement surrounding the sleeve in threaded engagement therewith, and means for selectively restraining the sleeve from axial movement when rotating relative to the rod so that coarse adjustment of the trimmer knife is obtained; when the sleeve is rotated free of axial restraint, fine adjustment of the knife is obtained when the sleeve is rotated.
  • FIG. 1 is a side elevational view of a portion of a side trimmer shear, the adjustable side trimmer knife of which is mounted with the apparatus of our invention;
  • FIG. 2 is a vertical sectional view of the apparatus of our invention
  • FIG. 3 is an elevational view looking at the right side of FIG. 2;
  • FIG. 4 is a plan view
  • FIG. 5 is a sectional view taken substantially along the line VV of FIG. 4.
  • reference numeral 2 designates generally a side trimmer housing having an adjustable side trimmer LII knife 4 and a fixed side trimmer knife 6 rotatably mounted therein.
  • Side trimmer knife 4 is carried by a stub shaft 8 which is rotatably mounted in bearings (not shown) which are in turn mounted in an axially adjustable bearing box 10 within the housing 2.
  • Fixed side trimmer knife 6 is mounted on a stub shaft 12 which may be rotatably mounted in any conventional suitable manner.
  • a yoke 14 is secured to the side of the housing 2 opposite the adjustable knife 4 by means of bolts 16.
  • An adjustment rod 18 having a flange 20 at one end is attached to the bearing box 10 by means of bolts 22.
  • the flange 20 may be sealed by an O-ring 24 made of rubber or similar material.
  • the adjustment rod 18 is formed with circumferential threads 26 intermediate its ends which are in engagement with the internal threads 28 of a differential screw which is in the form of a differentially externally and internally threaded sleeve 30. Internal threads 28 of the sleeve 30 differ in size from the external threads 32 on the sleeve.
  • internal threads 28 are 18 size, i.e., 18 threads per inch and threads 32 are 16 size, i.e., 16 threads per inch. It will be understood that the internal and external threads may be of any desired size so long as the sizes are different. The reason for the differential threading will become apparent hereinafter.
  • An elongated nut 34 having a circumferential flange 36 at one end surrounds and is in threaded engagement with the sleeve 30.
  • the assembly of nut 34, sleeve 30 and adjustment rod 18 pass through an opening 38 in the yoke 14.
  • Needle bearing 40 and hardened washers 41 are located on the inside and outside of the yoke 14 ad jacent the opening 38 and the nut 34.
  • Nut 34 is normally rotatable in the bearings 40.
  • Three nylon set screws 42 are disposed in the flange 36 on the end of the nut 34 to provide a locking connection between the nut 34 and the sleeve 30.
  • a nut 44 is threaded on the outwardly projecting end of the nut 34 seated againstthe outer hardened washers 41 on the outside of the yoke 14.
  • the nut 44 on the outer end and the flange 36 on the inner end of nut 34 prevent lateral movement of the nut 34.
  • Nut 44 may be locked in position by means of a nylon set screw 45.
  • a locking pin support 46 is attached to the yoke 14 by means of bolts 48.
  • the pin support 46 is a housing for a threaded locking pin 50 which is adapted to engage any one of a plurality of holes 52 in flange 36 on the end of the nut 34 to prevent rotation of the nut 34 relative to the sleeve 30 during fine adjustment of the knife 4, as will be more fully explained hereinafter.
  • Lubricating holes 54 may be provided in the yoke 14, nut 34, and sleeve 30, as best shown in FIG. 2.
  • a hand wheel generally designated by reference numeral 56, having a flanged hub 58 is secured to the-projecting end of the sleeve 30 by means of a square key 60 secured in place by a set screw 62 located in the hub 58 of the wheel 56.
  • An index dial 64 whose face may be divided into seven major divisions and each major division divided into five minor divisions, is attached circumferentially to the hub 58 of the wheel 56 and is secured by means of a half dog set screw 66, the end of which is received in a circumferential groove 68 extending around the hub 58.
  • An indicator pointer 70 which extends over the index dial 64 is attached by means of a set screw 72 in a half-split locking collar 74 which is normally clamped on the end 76 of adjustment rod 18 which projects outwardly of the outward end of the sleeve 30.
  • the collar 74 is disposed adjacent the end of the sleeve 30.
  • a bolt 78 secures the locking collar 74 around the adjustment rod 18.
  • the sleeve 30 may be provided with an internally disposed ring bearing 80 of bronze or similar material which slides along rod 18 to provide support.
  • the locking pin 50 is threaded out of the hole 52 in the flange 36 and the sleeve 30 is rotated by means of the hand wheel 56.
  • the adjustment rod 18 together with bearing 'box can move laterally relative to the sleeve 30 either to the right or the: left, depending on the direction of rotation of sleeve 30, when the sleeve is rotated.
  • the hand wheel 56 is backed-off until locking pin 50 is aligned with the nearest hole 52 in the flange 36 and the locking pin is inserted in the hole to prevent rotation of the nut 34 relative to the sleeve 30. Since the nut 34 is now fixed against rotation and the adjustment rod 18 cannot rotate but only translate, rotation of the sleeve 30 by means of wheel 56 produces a relative axial motion between the sleeve 30 and the adjustment rod 18.
  • the sleeve Since the external threads on sleeve 30 are size 16, the sleeve translates one-sixteenth or 0.062 inch in one direction "with each complete revolution of the wheel 56 while adjustment rod 18, which is in threaded engagement with the size 18 internal threads of the sleeve 30, will move one-eighteenth or 0.05 5 inch in the opposite direction at the same time. Therefore, the resultant rate of travel of the adjustment rod 18 is the difference between 0.062 and 0.055 or 0.007 inch per complete revolution of the hand wheel 56. This provides fine adjustment of the adjustable knife 4 relative to the fixed knife 6.
  • the hand wheel 56 is then rotated until there is again zero clearance between the two knives.
  • the locking collar 74 is then clamped into position abutting the end of the sleeve 30.
  • the set screw 66 is now loosened and theindex dial 64 is set so that the zero marking is under the indicator pointer 70. Fine adjustment is then continued until the desired clearance between the two knives is achieved. The operator can make the adjustment any time necessary without shutting down the side trimmer. He can also determine the amount of clearance by reading the index dial.
