Abstract: A single cycle/multiple cycle dual mode pneumatically driven fastener driving tool utilizes a resettable valve, trigger apparatus, work contact element (WCE) and a mode selecting trigger blocking pin. With the pin in place, the trigger must be released then depressed for each tool actuation. The tool is actuated only when the WCE is also depressed but without regard to the sequence of trigger and WCE depression. In a multiple cycle mode, the pin is removed and the actuation valve is reset either by trigger extension, or by WCE extension for "bottom contact" operation. The tool can be activated by full trigger release and depression while the WCE is held against a work surface. No particular sequence of WCE and trigger depression is required in this second mode. Apparatus and methods are disclosed.

Abstract: The fishing rod alarm apparatus is designed to provide the user indications of pressure on the line caused by the bite of a fish. The apparatus has a molded housing that contains an alarm system and a power source. The alarm is attached to a primary pin. A metal rod controlled by a magnet is held away from the primary pin when no pressure is maintained on the fishing rod. The metal rod is in normal contact with a secondary pin via a second magnet, and the secondary pin is attached to the power source. When pressure on the fishing line causes the metal rod to come into contact with the primary pin, the circuit is completed and the alarm will sound. As the pressure is increased the metal rod will be pulled away from the secondary pin and magnet which will result in the alarm being silenced. The magnet is positioned on a moveable slide to allow for changes in wind or water conditions such as current. When pressure is released from the line the magnets will return the metal rod to its original position.

When it is desired to remove the staple, the bight is gripped and rotated until it breaks away from the legs.

Abstract: This invention is a tool for either inserting the stem of a flag or marker in soil or rocky terrain or providing a hole therein of sufficient size to receive the stem of a flag. The tool is made up of three main components, these being an inner rod, an outer pipe and a pair of collars attached near the ends of the inner rod. The outer pipe is positioned between the two collars. The inner rod is notched on one end to facilitate inserting the tool. To insert the flag, the user places a bend in the flag stem and then places the stem inside the notch. By pounding down on the lower collar (which is attached to the inner rod) with the outer pipe the notched end and flag stem are driven into the ground. When the flag has been inserted to a desired depth, the tool is extracted leaving the flag inserted in the ground. Alternatively, to insert the flag the tool is used to create a hole of sufficient size wherein the flag is then inserted.
