Abstract: A floral wrapper comprises a body of a flat board stock material having four score lines. These score lines extend longitudinally, and are spaced angularly about a center located beyond the lower end of the body. Four contiguous segments are thus defined. Notches extending inwardly from the sides of the outer segments extend at least to the outer score lines whereby the outer segments are divided into upper wings and lower wings independently foldable about their score lines. The lower wings may be folded one over the other and about the stems of flowers to form a holder therefor as well as a grip for the wrapper. The upper wings can assume a substantially flat or trough like orientation for display of a relatively wide floral presentation, or the upper wings can assume an orientation in which they, along with the lower wings are overlapped to form a three sided box configuration for enclosing a floral presentation. The notches form a seat for a tie or ribbon.

Abstract: A ball joint comprises companion inner and outer hollow ball sections each comprising a major segment of a sphere. Spring means within the ball sections urges a friction pad into engagement with the interior surface of one of the sections. Screws within the ball sections adjusts the spring force, the screws being accessible for movement through a series of openings in one of the ball sections.

Abstract: The center locator utilizes a probe mounted for limited universal movement by a ball and socket arrangement. The center locator is affixed to the machine tool spindle so that the center of the ball coincides with the axis of the machine tool spindle. One end of the probe, provided, for example, with a sharp point, is placed in registry with a punch mark or pilot hole. The other end of the probe cooperates with two orthogonally located sensors. Each sensor includes a plunger confined for rectilinear movement by a hollow calibration nut, the plunger of one sensor being movable in the X direction in a plane at right angles to the spindle axis, and the plunger of the other sensor being movable in the Y direction in said plane. Springs cause the plungers to maintain contact with the probe end to follow the probe end along the X and Y axes respectively. The ends of the plungers are flat and move inwardly and outwardly of correspondingly flat tactile ends of the calibration nuts as the probe tilts in its mounting.
