Abstract: An improved mechanism for securing a parison molding cone atop the plunger shaft of a glass container-moulding machine. A one piece collar is secured to the head of the shaft by a bayonet tongue-and-groove assembly. The collar has a crenulated inwardly projecting flange around its upper rim. The base of the molding cone has an outwardly projecting crenulated flange around its lower rim. The flanges of each part are shaped and dimensioned to mesh together, thus allowing the flanged part of the base to be inserted into the top section on the collar then rotated into a locking position. Two spring-loaded locking members mounted into the collar engage recesses in the flange of the molding cone in order to prevent rotation of the molding cone away from its engaged position. A locking pin located in a vertical channel in the collar when forced down by the cone engages a recess or groove in the shaft and is locked there permanently by the cone while it remains in its engaged position.

Abstract: An ornamental ceramic fitting is mounted between two spaced, confronting, axially aligned, tubular members. The distance between the confronting ends of the tubular members is less than the corresponding axial length of the ceramic fitting. The ceramic fitting includes a threaded rod extending therethrough along the axis thereof and a well in each end of the fitting surrounding the threaded rod. The depth of the well in one end exceeds the difference between the axial length of the fitting and the corresponding axial distance between the confronting ends of the tubular members. The fitting is first placed on the end of one of the spaced tubular members and twisted to a position past the normal seated position. This allows proper alignment of the end of the other tubular member, whereupon the fitting is twisted in the opposite direction to properly complete the mounting operation.

The relative heights of the work surfaces (14) may be subsequently adjusted by tightening or loosening either of the screws (56).

Set screws fix the positions of the plugs axially in the pipes and also urge the connector into each pipe, which urges the outward faces of the plugs into contact and locks the pipes together.

Abstract: A method of driving composite timber pile sections provides a pair of timber pile sections, the first of which is driven into earth a distance leaving the butt of the pile exposed. A splice element is embedded into the remaining pile section and leveling material is added to the top of the first pile section.

In the preferred embodiment the splice element is a cylindrical element having a hollow inner bore which during operation contains the leveling material. An initially displaceable but later setting, non-displaceable material such as mortar (a mixture of cement, sand and water) could be used as the leveling material.

Abstract: A flexible mechanical coupling for torque transmission is capable of being connected and disconnected by only manual manipulation. The collar of the coupling has diametrically opposed cutouts in its sidewall for loosely receiving complementally shaped resilient locking members which in turn are held in place by a sleeve telescopically disposed over the collar. Flats formed in the shaft beneath each cutout are engaged by the respective members for locking the shaft and the collar against relative rotation.

The connector includes an annular sleeve engageable about the outside of the new pole section. The sleeve projects beyond the new pole section and has push plates positioned within the sleeve to embrace the distal section to hold it socketed therein. The push plates are engaged by means of bolts anchored in the sleeve.
