Abstract: The present invention involves a spark plug boot removal tool having a handle portion, an extension portion, and a grasping portion. The handle portion includes a spring-loaded trigger. The grasping portion includes a fixed grasping member and a rotatable grasping member. The extension portion includes an elongated flexible shaft enclosing a control rod that is attached to a triangular block. When the grasping portion is positioned over a spark plug boot, the trigger is compressed, causing the control rod to pull the block, causing the rotatable grasping member to join with the fixed grasping member to clamp around the spark plug boot. Both grasping members have an angular bend that allows the user to position the elongated flexible shaft outside of the engine compartment when exerting a force on the handle portion to remove the spark plug boot, thus minimizing the risk of injury.

Abstract: A pipe ring crimping tool providing significant mechanical advantage for applying force with a sufficient jaw opening and minimal external dimensions, minimal handle span and minimal handle length throughout the operational cycle. The tool is compact and lightweight to allow reach and access of the jaws into confined spaces. The tool utilizes a link and pin mechanism to translate the operator hand force exerted on the handles into a crimping force in a manner which allows for smooth application of operator hand force while increasing the crimping force as the pipe ring is compressed. The tool configuration by minimizing the handle spread, allows for single-handed operation of the tool or closely held two-handed operation. The tool includes a link mechanism designed to provide smooth crimping force and to preclude tool locking up and excess friction. The handles move laterally in opening the jaws to their maximum spread and are closed rotationally when crimping the pipe ring.

Abstract: A crimper for crimping cable terminals, cable connectors, and similar materials to electric conductors, optical conductors, etc. has two handles (2 & 7) that can be displaced toward each other and two crimping jaws (3 & 5), whereby one crimping jaw (5) is mounted so that it can move on the other (3). The moving handle (7) is mounted on an articulated support (19) on the moving crimping jaw (5). A toggle-lever drive mechanism consists of a pressure-application arm (8) and of a toggle-lever section (18) on the moving handle, whereby the ratio between lengths is at least approximately 2:1. The closing motion of the toggle-lever drive mechanism is terminated just before the extended state is attained by stops (24 & 25). At least one articulated support (19 or 20) can be displaced to vary the pressure. There is an automatic locking mechanism with a resiliently movable but stationary latch (11) that prevents the crimper from opening before crimping jaws have closed.
