Abstract: A portable linear fastener driving tool is provided that drives staples, nails, pins, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston further compresses the gas above the piston, thereby preparing the tool for another driving stroke. In an illustrated embodiment, the tool exhibits an inverted U-shape tri-chamber design for the central cylinder, a left-side pressure chamber, and a right-side pressure chamber. In one illustrated embodiment, the lifter motor is configured to have its longitudinal axis substantially parallel to the longitudinal axis of the working cylinder, thereby making this tool more compact. Other embodiments show the angle to be between 0-90 degrees.

Abstract: A frac plug with lower slips and a lower cone. In embodiments, a lower cone ramp angle is greater than or equal to a cone bevel angle and a slip inner cut angle. This geometry enables the fins of the cone to not interact with the lower slips, which may not break the lower slips as the lower slips move over the cone. Instead, the lower slips may break due to stresses caused by the tendency of the lower slips to expand as they lower slips interact with the ramp of the lower cone.

Abstract: A portable linear fastener driving tool is provided that drive staples, nails, or other linearly driven fasteners. The tool uses a gas spring principle, in which a cylinder filled with compressed gas is used to quickly force a piston through a driving stroke movement, while a driver also drives a fastener into a workpiece. The piston/driver is then moved back to its starting position by use of a rotary-to-linear lifter, and the piston again compresses the gas above the piston, thereby preparing the tool for another driving stroke. The driver has protrusions along its edges that contact the lifter, which lifts the driver during a return stroke. A pivotable latch is controlled to move into either an interfering position or a non-interfering position with respect to the driver protrusions, and acts as a safety device, by preventing the driver from making a full driving stroke at an improper time.

Abstract: A battery adapter can be used with an off-brand battery manufacturer to energize a power tool. The battery adapter is configured to monitor the voltage, temperature, and power level of the battery. Monitoring these levels helps prevent the tool from overdischarging the battery, as well as to prevent overheating. The battery adapter has a visible battery power level indicator, actuated by a switch, which visibly displays to a user a general indication of power left in the battery. The battery adapter is able to electrically disconnect the battery if the monitored temperature reaches a certain threshold. The battery adapter is also able to electrically disconnect if the battery adapter and off-brand battery are connected to a recharge station.
