摘要： A hydraulically actuated tool comprising a frame; a hydraulic fluid pump connected to the frame; a ram movably connected to the frame and adapted to be moved relative to the frame by hydraulic fluid pumped by the pump; and a hydraulic fluid reservoir connected to the pump. The reservoir is located proximate an exterior portion of the frame along a path of at least about 180°0 relative to a longitudinal axis of the tool. The reservoir does not extend beyond a rear end of the frame.

摘要： A hydraulic spike puller comprising a frame with a chute, a hydraulic drive section connected to the frame, and a spike contacting section connected to the hydraulic drive section and movably located in the chute. The improvement comprises the spike contacting section comprising two jaws pivotably connected to each other and a friction system extending from the jaws and contacting opposite interior sides of the chute. The jaws each have a spike contacting claw section which, when the jaws are in an open position, have a back surface adjacent an interior side of the chute to block an area between the chute and the back surface. The claw sections have substantially non-curved bottom faces which, when the jaws are in the open position, can push a spike out of the chute. The claw sections are shaped to prevent a spike from being caught between the chute and the back surfaces of the claw sections.

摘要： An operating handle system for a hand-held power tool comprises an operating handle including first and second courses enabling it to be gripped in first and second orientations, respectively. A trigger is movably attached to the operating handle for movement between an operative position for energizing a motor for driving an operating element such as a grinding wheel and an inoperative position at which the motor is de-energized. The trigger includes a first portion associated with the first course and spaced therefrom when the trigger is in the inoperative position and contiguous therewith when in the operative position. The trigger includes a second portion associated with the second course when the trigger is in the inoperative position and contiguous therewith when in the operative position. The first and second courses are mutually perpendicular as are the first and second portions. The trigger is pivotally attached to the operating handle such that when the trigger is in the inoperative position, the first portion and the first course are angularly disposed and the second portion and the second course are angularly disposed, and such that when the trigger is in the operative position, the first portion and the first course are contiguous, and the second portion and the second course are contiguous. The operating handle is generally U-shaped including a third course projecting from the second course at a location distant from the first course and being generally parallel to the first course.

摘要： An electrical terminal connector comprising a connector body and a set screw. The connector body has a block section with a conductor receiving passageway. The set screw is connected to the block section to intersect the conductor receiving passageway. The block section further defines a porthole extending therethrough. The porthole intersects the conductor receiving passageway forming a lower recess therein. When a conductor is inserted into the conductor receiving passageway, the recess receives a portion of the conductor which is clamped down upon by the set screw.

摘要： A removal tool is operable for separating components of an assembled electrical connector used for connecting electrical conductors together. The electrical connector includes a tapered connector sleeve having a general "C" cross section with a slot defining a stop ledge and a wedge having a latching ledge which engages the stop ledge when inserted into the slot preventing removal of the wedge. The removal tool with a first block member includes outwardly projecting ears for selective insertion into the slot for engagement with the stop ledge. A second block member includes outwardly projecting slide pins. The first block member is slidably received on the slide pins for movement toward and away from the second block member, a removal blade on the second block member having a tapered nose member projecting toward the first block member and an integral shoulder on the second block member facing the first block member and spaced from the removal blade in a direction away from the first block member. When the assembled electrical connector is positioned on the removal tool with the ears projecting into the slot of the connector sleeve and the tapered nose member is inserted between the wedge and the connector sleeve, movement of the first block member toward the second block member causes the latching ledge of the wedge to disengage from the stop ledge. With continued movement of the first block member toward the second block member the shoulder engages the wedge and forces its removal from the connector sleeve.
摘要翻译：拆卸工具可操作用于将用于将电导体连接在一起的组装的电连接器的部件分离。电连接器包括具有一般“C”横截面的锥形连接器套管，其具有限定止动凸缘的槽，以及具有闩锁凸缘的楔形件，当插入到槽中时接合止动凸缘，防止楔形件移除。具有第一块构件的移除工具包括用于选择性地插入槽中的向外突出的耳，用于与止动突起接合。第二块构件包括向外突出的滑动销。第一块构件可滑动地容纳在滑动销上以朝向和远离第二块构件移动;第二块构件上的移除刀片具有朝向第一块构件突出的锥形鼻构件和在第二块构件上的整体肩部面向第一块构件并且沿远离第一块构件的方向与移除刀片间隔开。当组装的电连接器定位在拆卸工具上，其中耳朵突出到连接器套筒的槽中并且锥形鼻部件插入在楔形件和连接器套筒之间时，第一块构件向第二块构件的运动导致楔形件的闩锁凸缘与止动凸缘分离。随着第一块构件朝向第二块构件的继续移动，肩部接合楔并迫使其从连接器套筒移除。
