摘要： This disclosure relates to a sliding element on a machine, particularly a machine tool, and more particularly, a tailstock for supporting a workpiece during a machining operation. During such a machining operation, the tailstock is subjected to momentary forces in excess and in opposition to the force normally required to hold the tailstock center in contact with the workpiece. The means for holding the tailstock positively against such forces is a body of hydraulic fluid applied to the tailstock center by means of a piston and cylinder. The pressure in the cylinder is only sufficient to hold the piston in contact with the tailstock center, but not sufficient to resist the momentary excessive forces. Such resistance is provided by locking the body of fluid against movement. This is accomplished by one check valve in a line through which fluid is suppled to the head end of the cylinder. Another connection is provided to the head end of the cylinder which includes a pilot-type check valve for preventing movement of the fluid out of the cylinder during the machining operation, but which may be opened when the tailstock center is retracted to discharge fluid from the head end of the cylinder direct to a reservoir without passing through a reversing or other control valve when the tailstock center is retracted. The pilot-type check valve is located as close as possible to the head end of the cylinder so that practically all of the fluid in the cylinder is discharged direct to the reservoir along with any accumulation of air.

摘要： This disclosure relates to work gaging devices for machine tools in which gas under pressure maintains a sensing member in contact with a workpiece. It also includes a container for the gas having a volume substantially greater than the displacement of the sensing member of the gage so that gas pressure is not affected by movement of the sensing member. The container serves as a junction box for electrical components such as a gage signal amplifier and conductors, as well as the gas. The connection between the junction box and the gaging device is a single conduit for both the electrical conductors and the gas. In order to prevent escape of gas through the electrical conductors and conduits connecting the junction box and an associated machine control panel, the electrical conduits, at this point, include gas-tight plug connections.
