Abstract: A compression tool (10) crimps both cylindrical (12) and "H" type (75) connectors. The jaws (22) of the compression tool have a first part which is defined by a nib area in which there is a nib (44) on either jaw and a base nib (46) which is moved into the nib area by a yoke (36) which is in turn moved by a manually operated hydraulic section (18) of the tool. Operation of the hydraulic section causes the nibs to converge upon a connector placed therebetween to effect the crimp. Alternatively, a connector, e.g., an "H" type connector, may be placed in a second part of the jaws. The second part includes opposing "C" shaped sections which also effect a crimp in response to the hydraulic operation. Additionally, the tool is adaptable to receive dies (76 and 78) which allow customized crimping and cutting.

Abstract: A compression tool head assembly for compressing a metal connector about a conductor. The assembly includes a head section having two, opposing arms moveably connected thereto, each of the arms having a compression point thereon; a rigid column disposed between the opposing arms and having a die mounted therein, the die having a compression point at one end and a mechanism for centering the cylindrical connector over the compression point at approximately a central location between the arms prior to compressing the connector; a hydraulic pump section is connected to the head section and operates to move the head section towards the rigid column; the arms have cammed surfaces which interact with rollers fixed to the rigid column to cause the arms to move towards each other as the head is moved towards the rigid column; as the arms move towards each other the compression points on the arms will compress an article disposed therebetween.

Abstract: A hydraulic apparatus for converting hydraulic pressure into mechanical movement for operating a tool or other device, operated by a pump block having a bore therein and a moveable plunger disposed within said bore. A cylinder is disposed over the pump block. The cylinder is captively held over the pump block and is moveable with respect thereto along the common axis. A fluid reservoir is defined between the cylinder and the pump block, and contains the hydraulic fluid. The plunger is operated by a pair of moveable arms secured to the apparatus and causes pressure to build in the fluid in an inlet chamber which communicates between the pump block and the cylinder. A pressure control valve is mounted adjacent the pump block and limits the hydraulic pressure which may be applied in the system. A release valve and apparatus is provided for releasing the hydraulic pressure and returning it to the reservoir.
