The invention provides a stem for a watering nipple for use in supplying water to poultry. The stem is hollow and formed of coiled material in a manner similar to that of a coiled spring such that the stem has a number of turns and minuscule gaps provided between adjacent turns. Upon actuation of the nipple, a water-tight seal is broken such that a majority of the water is directed to flow within the stem and directly into the mouth of the poultry. Some water, though, will flow along the outer s...

A stem regulator for direct mounting on the valve of a high pressure gas cylinder to provide a reduced delivery pressure for components or circuits of lesser pressure rating. The main body of the regulator, which contains its working parts, is adapted to serve, for example, as an inlet nipple for connecting the cylinder valve to a conventional adjustable pressure regulator. At one end, the body has a cylinder valve coupling face and nut and at the opposite end has an adaptor threaded to mate wit...

A clamping stem is provided for concurrently securing a bicycle fork frame steering tube and a bicycle handlebar together. The clamping stem has a mounting bracket formed as a U-shaped structure with a pair of opposing mutually parallel legs with coaxial openings defined through the legs near the free ends thereof. A steering tube saddle block having a vertically oriented concave surface is disposed between the mounting bracket legs facing the steering tube openings therein. A handlebar saddle b...

A stem for a watering nipple for use in supplying water to poultry is provided. At least a portion of the stem is hollow and formed of coiled material in a manner similar to that of a coiled spring such that the stem has a number of turns and minuscule gaps provided between adjacent turns. Upon actuation of the nipple, a water-tight seal is broken such that a portion of the water is directed to flow through the hollow interior of the stem, and preferably directly into the mouth of the poultry. S...

An improved stem for a bicycle comprises a column member having a top end, a first pivot mechanism and a second pivot mechanism which are provided on the two sides of the top end respectively; a sleeve member for fixing a handlebar, having a rod therefrom which defines a third pivot mechanism and a fourth pivot mechanisms on the two sides thereof; respectively and a lateral member including a left connecting part and a right connecting part wherein each of the left and right connecting part has ...

An improved stem for a bicycle comprises a pivot member having a lateral member and a locking member attached to the underside of the lateral member, wherein the pivot member has two free ends each having a pivot portion and the locking member has two free ends as well; a column member having a first connecting mechanism at the top thereof for pivotally connecting to the pivot portion; and a sleeve member securing a handlebar, and being provided with a second connecting mechanism at the free end...

A valve stem formed by evaporative pattern (or lost foam) casting a hollow or solid rod member inside of the elongated outer member. Since the stem is thereby cast to near net shape, little machining is required to finish it. The elongated member can have on its outer surface coarse square threads, a thrust ring, a flattened transition and a retaining nut threaded end. The rod member can advantageously be made of a material that is stronger and less expensive than that of the copper base alloy o...

This invention relates to a valve stem for a gas-lighter refill pack, the stem having a bore extending lengthwise therethrough for directing gas from the pack to a lighter, wherein the stem at its free end is shaped to enable the refill of both a lighter having a ball-type of valve and a lighter having a pin-type of valve with a central passage therethrough for the passage of gas.

The disclosure comprises an artificial stem for a short stem cut flower such as a cymbidium orchid, which includes a stiff, relatively large exterior tube of a suitable length to support the flower from a base which may be a reservoir consisting of a moistened cake of florist's foam, and a flocked wire centrally disposed within the tube and loosely wrapped along its length with a strip of absorbent cotton. The flocked wire is somewhat longer than the exterior tube to extend at its upper end into...
