    Abstract: Cutter suitable for artificial flower stems. Typically, plastic coated wire stems are cut with hand cutters to various lengths in preparing artificial floral arrangements. The invention requires far less physical effort by the operator than is required when using conventional wire cutters. In the preferred use of the preferred embodiment of the invention, an uncut stem is inserted crosswise through two elongated holes in the guard housing. When the cutter jaws open, the stem is pushed into the open jaws and is cut to a desired length from the flower end when the jaws close. In the preferred embodiment of the invention a gear reduction motor drives an arm and cam roller assembly. That cam roller forces the top handle of the cutter downward causing the jaws to close. As the cycle continues, the cam roller raises and a spring causes the jaws to open.

The switch is operable by the thumb or the finger, such that left and right handed users have operational parity regardless of blade orientation, which hand is holding the saw, or whether the thumb or finger is operating the switch. Parallel receding blade guard edges form a forward notch enabling forward cutting. The blade is interchangeable and a carrying case, belt holster attachment, and special battery charger are provided. The battery charger charges the battery while the battery is in the saw or when it is removed.

  • Patent number: 6082420
    Abstract: A flip top housing apparatus for side saw and topping saws used with a tree processing apparatus. The apparatus comprises a bottom section which attaches to one side of a plurality of hinges and a top section which pivotally attaches to the opposite sides of the hinges such that the top section is selectively moveable between a processing position atop the bottom section, shielding the saw blade from the surrounding environment during tree processing, and the transport position adjacent the bottom section, for allowing the housing to avoid low clearances during the transporting of the tree processing device. A lock comprising a handle portion, which fixedly attaches to the top section, and a receiving portion, which fixedly attaches to the bottom section, allows one to fasten the top and bottom section together during the processing position.

  • Patent number: 5647260
    Abstract: A roller die cutting machine includes a base having a drive roller assembly generally centered thereon between opposing side edges. A first table is located between the drive roller assembly and the first side edge to support a die assembly, and a second table is supported on the base opposite the first table to support a die assembly. A crank is connected through a set of gears to the pressure roller to rotate the pressure roller and to draw a die assembly through the drive roller assembly, to thereby cut stock positioned on the die assembly. A cover on the drive roller assembly includes a pair of inwardly projecting lips which will contact the pressure roller and produce an audible sound as a consumer's hand approaches the cutting location of the pressure roller.

  • Patent number: 5435218
    Abstract: A tobacco bale slicing machine having a support structure with an inlet opening for the insertion of a bale, and with an outlet portal. A conveyor transfers a bale from the inlet opening to the outlet portal in which there is a guillotine-like cutting device. A thrust device bears against the rear end surface of the bale to urge it towards and through the outlet portal in a controlled manner. The thrust device includes a motor-driven carriage disposed above the conveyor and has a thrust member mounted on an arm which moves between a raised and lowered position. When in a lowered, working position the thrust member can be brought to bear against the rear end surface of a bale carried by the conveyor in order to urge it toward the outlet portal in a controlled manner.

  • Patent number: 5317944
    Abstract: An adjustable protecting guard apparatus for a table saw having a guard positionable over the saw blade. The adjustable protection guard apparatus has a telescoping arm extending from one end of the saw table which supports a guard superstructure. A hinged connection on an edge of the guard superstructure permits the guard superstructure and the attached guard to pivot up and away from the saw blade. A control module simultaneously deactivates the motor rotating the saw blade with the pivoting of the guard superstructure. The control module has a multi-position key switch having a by-pass position permitting pivoting of the guard without de-energizing the motor. This permits difficult cuts to be made which would not be feasible with the guard in place. An anti-kickback pawl is also provided within the guard and prevents the saw from rejecting a workpiece in a direction opposite to its feed direction.
