Latest Patents

One of Jollie's notable inventions is a hacksaw featuring a cam-actuated blade tensioning mechanism. This innovative hacksaw utilizes an elongated blade that is maintained under tension between the respective legs of the saw frame. One leg of the saw frame includes a fixed blade pin that receives a mounting hole defined at one end of the elongated blade. The other leg features a pin carrier with a blade pin that fits through the mounting hole at the opposite end of the blade. The pin carrier is pivotal, allowing it to switch between a blade release position and a blade securement position. In preferred embodiments, the pin carrier acts as a cam follower that engages an elliptically arcuate cam surface on a pivotal actuator member. This actuator member may include a lever portion that provides mechanical advantage during its pivotal movement. Additionally, a releasable lock mechanism is integrated to maintain the actuator member, and thus the pin carrier, in the blade securement position during use. This mechanism is designed to require the simultaneous occurrence of two events to permit the release of the blade, ensuring safety and reliability.
