Apparatus for the high speed automatic cutting of measured lengths of a multiplicity of materials in which the material is guidingly fed from a supply source centrally of a feed path by a pair of adjustable feed rollers driven by a stepping motor that measures the length of material to be cut in terms of the cumulative steps of the stepping motor, and in which a reciprocable cutter knife is actuated in each cutting operation by a controlled single revolution of a connected drive shaft. A presser member supported for movement with the cutter knife engages the material in advance of the cutting blade and holds the material during cutting. The feed rollers are adjustable to a preset operative position and are spring urged to this position, but are arranged for independent manual movement to a wider separation of the rollers than in the preset position. The urging spring is also adjustable to vary its effective urging force. A unique gear train drivingly interconnects the rollers and is arranged to maintain their teeth in meshed driving relation during and at the adjusted positions of the spaced rollers.

Multiple purpose cutter apparatus

Apparatus for successively receiving and transporting long cut lengths of wire from a wire cutting mechanism and stacking the cut lengths in a receiver, a pair of long looped belts being supported with confronting surface faces coacting to form a longitudinally moving V-trough having an inlet and coupled with the wire delivery end of the cutting mechanism. One of the belts is supported on a fixed frame structure, and the other belt is supported upon a pivoted frame structure, a power actuator being selectively energizable to swing the pivoted frame structure in a direction to separate the converging belts and form an elongate discharge opening along the bottom of the trough through which the delivered cut wire length in the trough may be discharged by gravity into a receiver, and thereafter swing the pivoted frame in an opposite direction to close the discharge opening. Controls are provided for manually delaying the opening and closing operations of the converged belts in response to a signal from the cutting mechanism at the conclusion of each of its wire cutting operations.

Automatic wire stacker apparatus

An automatic tool changing apparatus incorporated in a drilling machine or the like comprises a plurality of collets, each for supporting and selectively grasping a tool holder mechanism. Each of the collets is slotted in its upper and central portions to divide the collet into a plurality of arcuate sections. The central portion of each collet is of generally truncated cone-shaped configuration, and rests in a generally truncated cone-shaped bore in a collet support block. A pneumatic piston arrangement is connected to the collets for selectively pulling the collets downwardly in their respective collet support blocks to move the generally arcuate sections of each collet radially inwardly to grasp a tool holder mechanism. Spring return means are provided for moving the collets into their normal positions wherein they will support, but will not grasp the tool holder mechanisms.
