Multiple purpose cutter apparatus

Apparatus for cutting lengths of elongated materials, comprising:

• a main frame structure;
• a pair of rotatable feed rollers positioned in a material feeding path, one of said rollers being mounted on said main frame for rotation about a fixed axis;
• a yoke member rotatably supporting the other of said rollers;
• means guidingly supporting said yoke member with respect to said main frame for adjusting movements to vary the spacing between said other roller and said one roller;
• a head frame member supported on said main frame for rectilinear movements towards and away from said feed path;
• cutting means including a cutting blade rigidly connected with said head frame member;
• means for moving the head frame member towards the feeding path to effect a cutting operation of material on the discharge side of said feed rollers;
• means for holding the material during a cutting operation;
• and
• means for adjusting the operative position of said yoke, comprising:
• a bushing having external threaded engagement with a top frame member and an inner end head portion adapted to operably receive an adjusting tool;
• a lock nut having threaded engagement with the outer end of said bushing;
• an elongate stem member slidably mounted in a bore of said bushing, said stem having an inner end in threaded engagement with said yoke and an outer end providing a head portion adapted for manual manipulation of the stem;
• and
• a compression spring surrounding said stem with one end engaging said yoke and the other end engaging the inner head portion of said bushing, said spring being operative to urge said stem head portion into a position of engagement with the outer end of said bushing whereupon stem rotation will adjust the yoke to a predetermined operative position, and rotation of the bushing will independently adjust the urging force of the spring at said operative adjusted position of said yoke.
