Abstract: An improved handpiece for a meat-cutting tool of the type having a cutting blade rotatably mounted on a blade holder which is mounted on one end of the handpiece. A flexible drive cable enters the opposite end of the handpiece and is drivingly engaged with the blade by a pinion gear. The handpiece has a hollow handle formed of lightweight plastic which is removably mounted on the blade holder attachment portion of the handpiece by an externally threaded coupler. An O-ring is mounted within the bore of the coupler and is in sealing engagement with a tubular-shaped sleeve or ferrule mounted on the end of the drive cable casing. The O-ring prevents contaminants from flowing through the handpiece and along the casing and onto the meat product being cut by the blade.

Abstract: A portable knife sharpener comprising two duplicate bar or narrow plate-like clamp members connected together adjacent to but spaced from their one ends for pivotal movement about axes generally parallel with the planes thereof and having facing planar surfaces with linear edges at their ends closest to their pivotal connection. A thumb screw is threaded in one of the clamp members intermediate its end opposite to said one end and its pivotal connection with the other clamp member the end of which clamp screw abutts the other clamp member. A discrete flange or angle-like member is pivotally connected by one flange part thereof to the side of each of the clamp members not facing the other clamp member with the other flange part of the member extending normal to the planar surface of the clamp member to which it is connected. Each of said angle-like members has a plurality of apertures therein spaced like distances from the planar surface of the clamp member to which it is connected.

Abstract: A coring machine particularly designed for coring frankfurters or other similar food substances. The corer as utilized herein contemplates a housing for receiving the frankfurters, a cylindrical guide and a cutting tool. The guide is attached to the housing in a fixed relationship and in operation, the cutting tool is inserted into the cylindrical guide and in and through the frankfurter for coring out a center portion of the frankfurter. The same housing may then be utilized for filling the frankfurter with a suitable filling material.

Abstract: A portable, motor-operated cleaning device for removing leaves and other debris from rain gutters on buildings. An electric motor is pivotally mounted on the end of a telescoping rigid tubular handle with the electric cord for the motor extending along the interior of the handle to a switch mounted on the opposite handle end. A plurality of short sections of flexible line are mounted on the motor shaft for rotation with a high velocity by the motor. Each of the sections of line have a preformed configuration having a portion which extends in a generally radially outwardly direction from the shaft and an integrally connected portion which then extends in a generally concavely curved direction toward the direction of shaft rotation. A bracket is mounted on the motor housing and has a pair of rollers which are mounted at right angles with respect to a third roller to provide for rolling engagement with the horizontal and vertical outer edges of a rain gutter.

Abstract: An anti-theft door lock comprised generally of two sections, an outer spring loaded section and an inner section connected to the door locking mechanism in which the outer section is pushed downwardly exposing the inner section which can then be manipulated like a conventional door lock to either lock or unlock the car door.The anti-theft device is used as a replacement unit for the one originally supplied with the vehicle. It can be placed in the door sill without the need of any tools and is designed to be screwed onto the existing locking rod which actuates the door lock. Because of the inherent design features, the door lock cannot be actuated by the use of wire type devices, such as coat hangers by would-be car thieves.

Abstract: A system for supplying steam to equipment which uses the heat of the steam and not the pressure for performing work such as commercial laundry equipment. The system is a closed loop having a steam boiler which supplies steam directly to the equipment. A control valve regulates the amount of steam flowing through the equipment which determines the heat imparted to the equipment. The equipment is free of heat traps or other components which retard the flow of steam therethrough. The used steam flows into an improved condenser having a plurality of compartments which slows down the velocity of the steam to help facilitate the condensing process and to enable harmful air trapped in the condenser to be removed. Pumps remove the air from the condenser and maintain a vacuum within the condenser and steam return line from the equipment to maintain the steam flowing through the equipment at a desired rate.
