NEEDLE-VALVE RETAINER.
Application illed January as, 1923. Serial No. 615, t94.
To all whom it may concern:
Be it known that I, Gnonon A. Enron, a citizen of the United States, residing at 3234: Lothrop Ave, Detroit, in the county of Wayne and State of Michigan, have invented certain new and useful Improvements in Needle-Valve Retainers, of which the following is a specification.
This invention relates to bolt retainers and specifically to a needle valve retainer. The ohject of this invention is to provide a simple and inexpensive retainer tor an'adjustahle needle valve.
The devices heretofore in use have been provided only for a definite graduated adustment. That is to say they provided for th, th,'or th of a turn, and it is desirable to give much smaller adjustments than this; it a serrated surface with a large number of teeth is provided, the serrations wear down and the device thus fails to function. The device shown herewith provides an infinite number of positions and is adapted to be automatically retained in any one of them by friction.
Figure I shows a cross section through the center of the needle valve.
Figure II shows a transverse section taken on the plane XY of Figure I. I
Figure III shows the. development of the retainer and operating arms.
In Figures I, II and III, A indicates the needle valve threaded into a needle valve support B, which in its turn is threaded into the casting C. Dare the arms of the retaining device which is riveted to the end of the valve A and engages with considerable pressure on the cylindrical projection 15 of the piece ll. I! are the operating arms forming the handle of the valve A which are made integral with the arms D. G is the needle valve seat toward andaway' from which the needle valve A is adjusted.
The arms I) are inclinedltowards each other and are made concave on the inner face so as to increase the wearing surface upon the cylindrical surface E. The arms I) are sprung so that they press upon l6 with considerable pressure. The needle valve A is thus adjustahly retained in any position by'reason of the friction between thecylindrical portion 1%) and the arms 1) as shown in Figure ll. holder to get the necessary elasticity the piece formed by the arms D and I is made ot' mild steel and is stamped from sheet steel as shown in Figure III, and bent into the form shown in Figures I and II.
IVhat I claim is: a
A device of the class described, comprising a threaded needle valve, a needle valve support into which said. needle valve s threaded,-a cylindrical projection from said needle valve support, a plurality of prongs riveted to said needle valve, said prongs being adapted to 'frictionally engage with the said cylindrical project1on 'from said needle valve stipport,whereby at any fractional turn thereof said needle valve will be retained in position.
In testimony whereof I afiix my signature.
GEORGE A. EYNON.
