Abstract: A fishing worm threader which includes a handle having a threading needle projecting therefrom with the threading needle having in its sharpened tip end a pocket to receive the point of a fish hook. The needle is threaded through a worm either alive or artificial and the point of a fish hook is placed in the socket of the needle so that the worm can be moved from the needle onto the fish hook so as to be threaded onto the hook.

Abstract: An adjustable volume measuring cup in which the body of the cup is formed of clear plastic having a threaded opening in the axial center of the bottom thereof closed with a removable screw. A handle is threaded into the side of the cup and can be removed. A movable bottom of the cup is of cylindrical form and fits the internal diameter of the cup snugly so as to stay in position vertically in the cup when moved. The movable bottom has an axial threaded bore and the handle can be threaded into the threaded bore of the movable bottom by extending the handle through the opening left after removing the screw in the bottom of the cup so that the handle can then be used to move the movable bottom to a desired position within the cup in accordance with an external scale on the cup.The handle is provided with a screwdriver blade on its outer end for engaging the screw closing the opening in the bottom of the cup.

Abstract: An enclosure mountable on a rotary type lawn mower for completely isolating the rotating blade so that it cannot be accidentally contacted by a person's hands or feet, nor the blade be readily hit against upward projecting rocks; the enclosure consisting of a circular metal shield from the periphery of which steel fingers extend radially and downwardly so to form a cage within which the blade swings, the shield having a central opening for fitting on and rotating with respect to the motor shaft housing and positioned above the blade so to rotate and spread the cut grass as it moves outwardly from the blade and rotate on engaging an object as well as rotate due to the reaction of the uncut grass on the fingers during a grass cutting operation.

Abstract: A method of decorating a fabric in which an elongate strip of fabric is sewed to a base fabric along a line spaced inwardly from the edge of the strip of fabric. The base fabric with strips sewed thereto is then washed in a washing machine so as to cause the edges of the strips of fabric outside of the line of stitching to fray and to thus take on a decorative appearance. The invention also includes the fabric produced by this method with the strips of material being arranged in any desired decorative pattern on the base material.

Abstract: A plow cutter assembly to be used in the strip mining of coal, the assembly comprising a container having a plurality of steel spikes mounted at an angle on its lower face. A hoist pulls the assembly along the face of a coal vein and the spikes shave off layers of coal.

Abstract: A means to monitor the depth of water in a well and to prevent a pump from operating if the water level falls to a predetermined level, consisting of float and weight means operating a depth indicator and cutoff switch.

Abstract: A locking load binder having a conical lock tongue mounted on the handle and a keeper link secured to the yoke on one side of the handle and adapted to cooperate with the lock tongue to secure the handle thereto. The lock tongue includes cam driven locking balls which cooperate with the keeper link.

Abstract: An electric generating system in which oppositely rotating wind driven wheels are used, one to drive the rotor and one to drive the stator of an electric generator.

Abstract: The form fitting of shoes and boots of the instant invention includes the heating of the area of the foot gear which needs to be enlarged to accommodate the foot and simultaneously applying pressure from the inside of the foot gear to cause the heated portion of the foot gear to expand the desired amount. Pneumatically or hydraulically actuated cylinders are used within the foot gear to provide the required pressure and a number of different shoe contacting members are interchangeable to assist in shaping the expanded portion of the foot gear.

Abstract: An engine de-compression mechanism in which the valves to one or more of the cylinders are locked in open position to prevent fuel from being drawn into the engine cylinder during the normal intake stroke and to prevent compression back pressure on the piston during the compression stroke. The function of the de-compression mechanism is to put one or more of the cylinders of the engine out of operation to conserve fuel when driving at high speeds.

Abstract: A rack for guns or other sporting equipment to be mounted on the wheel well in the interior of pick-up trucks or other vehicles so that the guns or other equipment will be held securely in a protected position for easy access but not easily seen by persons outside of the vehicle.

Abstract: A control handle for saber saws for turning the saw about the axis of reciprocation of the saw using a rotating handle having its axis parallel to the work surface and perpendicular to the axis of reciprocation of the saw blade. The control handle is the main handle for manipulating the saw and is mechanically linked to the saber saw blade to permit the saw blade to be guided by rotation of the handle. A transversely extending shaft parallel to the work surface is also linked to the saber saw blade and has knobs on its opposite ends so that the blade may be guided therewith.
