The radial feed which applies the pressure is applied by a power train which includes a worm-worm gear combination driving a screw shaft-nut combination. After maximum pressure has been applied, the center distance is reduced by limited predetermined axial movement of the worm, without rotation, in which the worm acts as a rack to provide a predetermined limited rotation of the worm gear, and hence of the screw-nut combination.

Tools, machining devices or the like can be attached to the yoke. The nuts are driven simultaneously by a drive motor through a drive shaft extending therefrom.

Abstract: Various forms of tools are disclosed for effecting reciprocal movements between jaw members to be located between and exerting opposing thrusts on the flange and bolt head of a hollow wall anchor. For such an anchor driven through a plaster wall or wallboard with the flange brought flush against the inner surface thereof, the threaded bolt is unthreaded sufficiently to position the jaws as described. Operation of the tool to thrust the jaws apart causes the bolt to be drawn out axially, carrying the inner end of the anchor so as to decrease the distance between flange and inner end and deforming the anchor body for interlocking it with the wall material. Where such an anchor is initially only partly driven through the wall, due to its inner end being obstructed, the bolt is unthreaded and the jaws located between the thus spaced head and flange in the same manner.

Abstract: The ram of a hot-stamping press is driven by means of a movable rack that can be allowed to change position with respect to the ram. The rack engages gears on the end of the ram opposite its head, but during the initial portion of its stroke an air cylinder interior to the ram prevents relative motion between the movable rack and the ram. As a consequence, the ram moves at the same velocity as that of the rack during the initial portion of the stroke. Stationary racks are also provided, and additional gears mechanically linked to the gears engaged by the movable rack begin to engage the stationary rack toward the end of the stroke. This requires relative motion of the movable rack relative to the ram despite the force applied by the air cylinder inside the ram, and the velocity of the ram is thereby reduced to a fraction of that of the rack. This results in force multiplication toward the end of the ram stroke.

Abstract: A horizontally reciprocal ram is movably supported on a can bodymaker for forward and rearward movement of a ram forward end through a die assembly by stationary, spaced, hydrostatic oil bearing sleeves located rearwardly of the die assembly thereby isolating at least a major portion of the ram for support and alignment for remainder of the bodymaker. Drive mechanism supplying horizontal ram drive to a ram rearward end may include a movable hydrostatic oil bearing slide connected to the ram through various optional forms of drive connection means supplying varying degrees of relative flexibility between the ram and slide to thereby determine the degree of ram isolation by the bearing sleeves with an optimum of substantially full ram isolation. Included in certain of the drive connection means providing greater flexibility for greater ram isolation are variously located hydrostatic oil bearing pad assemblies.
