Abstract: Safety shield apparatus for a bottled gas tank valve includes a cover which fits over the valve and an internal flange or plate within the cover that fits underneath the valve handle. A tail portion secured to the cover extends outwardly beyond the vertically extending flange which is disposed arcuately about the valve handle and which comprises also a handle for the bottle. The tail portion includes holes which receive a lock to prevent the shield apparatus from being removed from the bottled gas tank.

Abstract: V-block apparatus for holding around object being worked on includes a base element which may be appropriately secured to a work bench or to a table of a drill press. The V-block includes a pair of angularly oriented sides or wings which define a trough for receiving a round object. At the juncture of the sides or wings is a bottom slot which may receive the tip of a drill after the round object has been drilled through to provide a pair of diametrically aligned holes. The V-block apparatus also includes friction enhancing elements to aid in holding the round object while the round object is being worked on.

Abstract: Sweep apparatus may be easily secured to and removed from a tine by a pair of flex pins. The sweep includes a plate and a pair of side flanges extending downwardly from the plate through which the flex pins extend. An adapter shoe is used to secure the sweep to a tine, or a tine may directly include a pair of laterally extending bores against which the flanges of the sweep are disposed and through which the flex pins extend to secure the sweep to the tine without the adapter shoe.

Abstract: Pin insertion and removal tool includes a main block and a holder cup or socket for holding a pin to be inserted to secure a tooth onto a shank of a bucket. The holder cup or socket is secured to a holder block which is in turn secured to the main block. An extractor pin is secured to an extractor block, and the extractor block is secured to the main block. Both the extractor pin and the holder cup or socket are spaced apart from the main block by predetermined distances. The main block includes impact portions which receive hammer blows to set the pin and to remove the pin, as required. Adjacent to the holder cup or socket is a pin setting face that is used to completely insert the pin after it has been started and is sufficiently into the tooth and shank to remove the socket and tool from the pin and to move the tool slightly to provide direct force against the pin for setting the pin by hammer blows on the pin setting impact portion of the main block.
