Abstract: Improved serviceability of cold metal cutting machines is accomplished in a modified gearbox structure enabling several annular components that are conventionally attached by press-fit to be attached instead by slide-fit for easy removal and replacement, eliminating hammering and/or heating required conventionally to release press-fit components. Press-fitting of a motor shaft coupling is eliminated by introduction of clamping slide-fit structure. Press-fits of two thrust bearings to the housing are eliminated by introduction of slide-fit adaptors. Instead of the conventional practice of making the saw rotor integral with the low speed shaft, a separate saw rotor bolted to the shaft enables easy replacement of the oil seal.

Abstract: A storage unit/workstation is described which allows efficient storage and use of several rolls of package wrapping material in conjunction with the tools needed to perform such wrapping. The storage unit/workstation includes a cabinet wherein the rolls of wrapping material are mounted to allow the wrapping material to be dispensed by unspooling it from the rolls. A working platform is situated below the cabinet so that the user may place a package on the platform and wrap it with wrapping material pulled from the cabinet. The platform may be stowed when not in use.

Abstract: A scissors for cutting, holding, and then releasing an elongated piece of string. The scissors includes a pair of conventional scissors with a spring-clip attachment. The spring-clip has a long leg, a short leg, and a semi-circular bottom portion attaching the legs together. The short leg is rigidly mounted to a first blade arm of the conventional scissors. While the blade arms pivot toward one another, a portion of the string is retained within the attachment after it is cut and then released from the attachment upon opening of the blade arms.

Abstract: Apparatus for supporting a coaxial cable, or the like, and effecting cutting and stripping operations to remove a portion of one or more layers which concentrically cover a central conductor. A single blade, having a circular cutting edge, is moved in an orbital path about the cable with rotary motion of a motor translated to orbital motion of the blade through a plurality of plates relatively movable on crossed, linear, roller bearings and a shaft eccentrically affixed to the motor with the shaft and motor axes at an acute angle to one another. The shaft extends through a spherical bearing mounted in one of the plates, thereby translating nutational motion of the shaft to orbiting motion of the plate which is directly attached to the blade. A unique clamping assembly includes a pair of jaws having respective gear racks engaging a single pinion gear on a motor output shaft for linear movement of the jaws by equal distances in opposite directions.

Abstract: A method for segregating and transferring a product from a web of material includes the steps of conveying the web of material between a punching roll and a counter pressure roll, the punching roll having at least one cutting edge and at least one suction orifice; punching-out the product from the web with the cutting edge; adhering the punched-out product on the punching roll under a vacuum connected to the at least one suction orifice; rotating the punching roll to position the punched-out product proximate to a conveyor belt; detaching the punched-out product from the punching roll; and transferring the punched-out product onto the conveyor belt. In certain embodiments, the suction orifice of the punching roll is ventilated with a gas stream to facilitate detachment of the punched-out product; and a vacuum is applied to the conveyor belt to draw the detached product thereto and hold it thereon under suction.

Abstract: A machine for slitting a metal sheet has a number of knife holder assemblies each containing a rotary knife. The knife holder assemblies are mounted for movement along upper and lower rotating shafts which rotate the knives during a slitting operation. The position of the knife holder assemblies is programmably controlled for efficient and accurate positioning and adjustment of the knives along the rotating shafts for a variety of slitting configurations. Additionally, each of the upper and lower drive shafts contains a pair of drive shaft sections that are normally connected together during operation and can be disconnected for servicing of the knife holder assemblies on the shafts. The slitting machine includes upper and lower frames that are movable relative to each other by adjustment of a pair of jack screws to slit metal sheets of differing thicknesses without labor intensive adjustment or reconfiguration of the machine.

Abstract: A “spring powered toggle joint lock” for a folding knife; comprising a blade lock of three primary elements. A rotating toggle link at the rear of the knife handle connected by a pivoting knee joint to a traveling toggle, which is in turn pivotally joined to the tang of the opening and closing blade. A spring configured so as to constantly urge the pivot points of the rotating toggle and traveling toggle into a straight line, generating an over-center action. The effect of the spring and toggle combination is to propel the opening blade towards open and the closing blade towards closed. Control pins attached to the traveling toggle and protruding to the surface of the handle, on both sides of the handle, provides the means to collapse the toggle lockup by thumb pressure, thereby allowing ambidextrous, one handed manipulation of a toggle locking folding knife.

Abstract: A rotating cutting apparatus comprising a cutting blade holder with at least one hole on the outside diameter of the cutting blade holder into which cutting blades are inserted and bonded to the cutting blade holder. The cutting blade holder encloses a center hole, so that the rotating cutting apparatus can be mounted to a drive shaft of machinery or secured to a cup that can be mounted to the drive shaft of machinery and driven by the machinery. The cutting blade holder can be made of a less expensive material, with only the cutting blade being made of higher-grade materials that maintains its cutting edge well. Additionally, in some arrangements of the present invention, the cutting blade may be sharpened on two sides so that the rotating cutting apparatus can be used for longer periods of time.

Abstract: A head for a line trimming apparatus includes a body member and a detachable cover that may include a replaceable insert for connecting the head to a drive shaft of a line trimming apparatus. The body member includes opposed openings and a filament-receiving channel for inserting an elongated flexible cutting filament into the head for retention thereon. A spring-biased clamp is supported on the body member and is engageable with the filament portion residing in the channel to releasably retain the filament connected to the head. An actuator button projects through an opening in the body member and is operable to be pressed to cause the clamp to release forcible engagement with a filament so that the filament may be removed and replaced. In one embodiment the clamp and actuator are an integrally formed part and the filament projects through openings formed in spaced apart arms of the clamp member.
