摘要： A boring machine includes a power unit having a housing, a drive member for engaging a boring bar, and a motor for driving the drive member to rotate relative to the housing. The boring machine also includes a bearing assembly comprising an inner bearing member defining a passage through which the boring bar extends, and an outer bearing member in which the inner bearing member is fitted in a manner permitting angular movement of the inner bearing member relative to the outer bearing member about axes perpendicular to the axis of the passage defined by the inner bearing member. In use, the bearing assembly is attached to a workpiece in a manner preventing movement of the outer bearing member relative to the workpiece, and a collapsible torque transmission linkage connects the housing of the power unit to the outer bearing member, whereby the housing unit is held against rotation relative to the outer bearing member.

摘要： A portable machine tool comprises a main spindle and a machine body that is rotatable relative to the main spindle. A take-off shaft is mounted in the machine body and is rotatable relative to the machine body, and a rocker arm is rotatable about the axis of the take-off shaft. A cam and follower mechanism converts rotation of the machine body to reciprocating rotation of the rocker arm, and a releasable clutch mechanism that is effective between the rocker arm and the take-off shaft can be switched between a first state in which it converts reciprocating rotation of the rocker arm to unidirectional rotation of the take-off shaft and a second state in which reciprocating rotation of the rocker arm has no effect on the take-off shaft.

摘要： A machine tool comprises a mounting member for attachment to a workpiece. The mounting member includes a bearing portion that has an external surface of circular cross section and is formed with an aperture in its external surface. A utility device has an internal peripheral surface that defines a cylindrical cavity for receiving the bearing portion of the mounting member in a manner that allows the utility device to move axially and rotationally relative to the mounting member. A clamp is actuable when the utility device is fitted to the bearing portion of the mounting member for releasably retaining the utility device against axial and rotational movement relative to the bearing portion. A spring-loaded detent member projects into the cylindrical cavity from the peripheral surface and is receivable in the aperture of the bearing portion for retaining the operating assembly against axial and rotational movement relative to the bearing portion in the event that the clamp is not actuated.

摘要： An improved portable milling machine adapted to grip a work piece and to cut a keyway through a clamping area. This is accomplished without releasing the grip of the milling machine on the work piece by forming an elongated slot in a bed plate with lands lying at opposite sides of the elongated slot. A clamp plate is arranged in stacked alignment with said lands and a work piece is gripped between the clamp plate and the lands of the bed plate. This structure permits a cutting element to pass through the elongated slot to cut a keyway upon the work piece while said work piece is gripped, the cutting action being performed through the clamped area. Improvements include interchangeable spindle construction allowing the use of a variety of cutter elements.
摘要翻译：一种改进的便携式铣床，其适于夹紧工件并通过夹紧区域切割键槽。这是通过在床板上形成细长的槽而将铣床的工具释放在工件上而实现的，其中平台位于细长槽的相对侧。夹板布置成与所述平台对齐，并且工件被夹持在夹板和床板的平台之间。这种结构允许切割元件穿过细长槽以在工件被夹持时切割工件上的键槽，切割动作通过夹紧区域进行。改进包括可互换的主轴结构，允许使用各种刀具元件。
