Abstract: A clamping device for setting a detail which has at least one oversized throughbore to a fixture base which has at least one threaded throughbore, the clamping device has six degrees of freedom, a longitudinally adjustable body portion which has an upper threaded portion and a lower threaded portion and is fixed in space so as to form a firm point for longitudinal rotation eliminating bending of the body portion during the setting, a flange disposed on the body portion which separates the upper threaded portion from the lower threaded portion, and a clamping arrangement disposed on the upper threaded portion of the body portion which provides single load line jacking and clamping to adjust and hold the detail in position with relation to the fixture base so that lock-up of the clamping device and the detail is prevented.

Abstract: A vertically adjustable, shock-absorbing mounting device for supporting an object comprises a foundation body including a metallic cover plate, and a support plate having an underside and a supporting surface for the object. The support plate includes a ledge protruding from the support at no more than two adjoining sides of the support plate for engaging and retaining the object on the supporting surface against rotation in relation thereto. A threaded spindle has an upper end connected with the underside of the support plate and a lower end connected with the cover plate, one of the spindle ends being in threaded connection and the other spindle end being in locking connection with the respective plate whereby rotation of the threaded spindle adjusts the spacing between the foundation and the support plate while the object is held against rotation by the retaining engagement with the ledge.
Abstract: Apparatus for raising and lowering a terminal comprising a support plate having a top surface to which a terminal is secured and a bottom surface to which are secured two cross bars mounted on a threaded shaft which moves the cross bars toward and away from each other. Four pivotable legs are positioned with respect to the cross bars so that movement of the bars in one direction pivots the legs to raise the support plate and its terminal, and movement of the bars in the opposite direction pivots the legs to lower the support plate and its terminal.
Abstract: A fabric dryer is mounted in an elevated posture above a support surface and a washing machine on a support stand. The support stand includes adjustable members by which the support stand and attached fabric dryer can be leveled and adjusted for proper height with respect to the support surface. Each base member of the support stand is formed from a C-shaped channel and the rear of the washing machine cabinet includes a pair of glide plates which are engageable with the lower flanges of the support stand base members to automatically level the washing machine and locate the top of the washing machine below the fabric dryer.
Abstract: A pumping method, principally for oil, allows the sucker rod to fall under gravity for the first part of the downward stroke, then decelerates the sucker rod to a slow rate of descent, so creating a pause in the sucker rod's motion. Shock-absorbing means are provided to eliminate the impulsive loadings imposed upon the sucker rod at either extremity of its motion in conventional pumping methods. Hydraulically and mechanically-driven apparatus is disclosed for carrying out the method.
Abstract: A low-profile theodolite leveling means comprises a tribrach assembly including three separate platforms of which the second is mounted upon the first by means of a pair of pivot elements which establish a first fixed axis of tilt of the second platform, and the third is similarly mounted on the second by means of a pair of pivots which likewise establish a second fixed axis of tilt, orthogonal to the first axis, for the third platform. Located in use between a tripod head and the base of a theodolite geodetic instrument, the tribrach assembly provides means for tilting the theodolite instrument with respect to independent planes defined by the orthogonally disposed axes of tilt and respective adjustment screw members.
