A valve stem has a thickness of hardfaced material on its outer diameter in the area contacting the stem packing where the seal is formed which prevents corrosion, erosion and/or scratching of the valve stem, thereby preventing formation of leak paths. A valve packing comprises a vertically stacked array comprising alternating metal pressure rings and graphite seals.

A valve stem button comprises a vertically elongated hollow body having a lateral face disposed between the top and bottom thereof, the face having a recess, the recess having an outlet port. A valve stem receiving socket is disposed in the bottom of the body and extends upwardly to a position intermediate the top and bottom of the body. A vertical cylindrical chamber having a closed cylindrical inner wall is disposed in the body intermediate the top of the socket and the top of the body, the wa...

An elongated sleeve surrounds and threadedly engages the depending end portion of a faucet stem having a nut securing it to a sink or basin. A thrust bearing, having a bore loosely surrounding the faucet stem, is secured to the end of the sleeve, adjacent the faucet nut, and is provided with radially disposed cutting blades projecting toward the faucet nut. The cutting blades are moved into splitting engagement with the faucet nut by manual angular rotation of the sleeve relative to the faucet s...

Means for affixing the scapular component of a shoulder prosthesis to the bony structure of the shoulder includes a T-shaped stem extending from a flange on the device. The stem has a substantially narrow or thin web having one side longer than the other, which disposes the base at an acute angle relative to the flange, such as approximately 15.degree.. The elongated base and the web are inserted through the bony structure with the flange in contact with outer regions. The base and web are cemen...

A valve stem cleaner and positioner for threaded valve stems. The cleaner and positioner is designed for use with threaded valve stems in which the portion of the valve stem to be cleaned is inaccessible from the ends of the stem as for example, in an open yoke of a valve and also for use in valve stems where an end is accessible as above the valve hand wheel. For the inaccessible portion of the valve stem the cleaner and positioner is made in hinged half portions with semi-circular members whic...

Apparatus for bending valve stems of inner tubes used primarily in truck tires which facilitates locating the area of bending contemporeous with readily controlling the bend angle of the stems. An apertured clevis is pivotally mounted on a housing that is grooved to receive a valve stem, with a cylinder and piston connected to the clevis for actuating same with respect to the housing to effect a bending of the valve stem. The housing contains a cylinder and piston for actuating rack and pinion m...

A seal for the valve stem of a poppet valve in an engine includes an elongated outer tubular body and a concentric inner tubular body with both bodies being connected at one end by a radial flexible web. The inner body is provided with an annular sealing lip for sealing engagement with the stem of the valve while the free end of the outer body has an internal diameter whereby it can sealingly encircle a cylindrical valve guide on the engine for the valve. Preferably a spring is positioned to enc...

A valve stem lubricating device. The lubricating device is designed for employment for use with valve stem valves that are difficultly accessible as in the interior of the valve yoke where the stem ends are protected and access is not available to the interior portion of the valve. The device is comprised of two hinged half sections or circular portions provided with lubricating material such that when the hinged sections are closed around the valve stem the lubricating material contacts the val...

A die stem for an extrusion press connected at its one end to a die holder including a first connecting construction such as a screw or a bayonet provided in the inner bore of the end portion of a sleeve received by the inner bore of the die stem, and a second connecting construction such as a screw or a bayonet provided at the rear end projection of the die holder, the second connecting construction being adapted to cooperate with the first connecting construction, whereby the compression stres...

A retaining device to hold a butterfly valve stem (26) in the valve body upon a shearing or breaking of the stem. The retaining device is mounted within a bore (38) in the valve body (12) beneath the stem packing and includes pins (44) extending from the stem (26) which engage in abutting relation a support ring (64) mounted in a groove (56) in the bore to restrain any outward movement of the stem.
