VALVE.

Specification of Letters Patent. y

Patented Jan. 16,1917.

. citizen of the United States, residing in the city of St. Louis and State of Missouri,

Vhave invented new and useful `Improvements in Valves, of which the following is a specitcation.

This invention relates to fluid pressure valves and has special reference to an improved valve for use in connection with pneumatic tires of vehicles.

Valves as now generally used in this connection are, relatively speaking. quitey complicated, and it is therefore one ot' the principal objects of m v invention'to provide a valve which shall be characterized by extreme simplicity in construction.

A further object of the invention is to provide a valve of they character indicated which shall be sensitive and reliable in operation, and, as an incident to its simple construction` one which will not be liable to get, out of order, and which will therefore have the maximum life.

The invention is illustrated in the accompanying drawing. in which- Figure 1 is a longitudinal sectional view through my improved valve and the casingy in which it is mounted; Fig. 2 is a view 1n elevation of my improved valve removed from the casingg'and Fig. 3 is a longitudinal sectional view of the lower portion of the valve member. showing it in open position.

Referring now to the drawing, the numeral 1 indicates a valve casing of a -wellknown type which is provided with an air duct .2 and reduced portion 3. said reduced portion 3 being provided with interior and exterior scre\vtlue:uls. and the portion of thc air duct immediately below said reduced portion of the casing being enlarged to provido a chamber l to accommodate a valve 5. This valve. is in lthe t'orm of a tubular shell and at its outer end is provided with a noncircular portion (i. and below .said non-circular portion with `a shoulder T against which is seated a .gasket S. Below said shoulder the tubular shell is provided with a screw-threaded reduced portion t). below Said screw-threiuled portion with a further reduced eylindrh 1 portion lil. and below this ortion witlii a still t'urthcr reduced cylin rical portion ll. the end of which forms the valve-scat. 'l`he numeral 12 indicates a hollow valve member which is slid ably mounted on the reduced portion 11 and receives the lower -end thereof, being closed at its outer end. The reduced portion 11 is provided with an annular shoulder 13 located Slightly above the lower end affording the valve-seat, and the upper edge portion ofthe valve member 12 is swaged or turned inward. as indicated at it, so that in the outward movement of the valve member 12 said swaged portion will engage the shoulder 13 and prevent the valve member from falling ofi1 of the valve shell. In the bottom of the valve member l2 l place a. ldisk or gasket 15 which is preferably of rubber, and against which the end 1? of theI Shell is adapted to seat to atlord a secure closure against the passage of air through said shell.

iThe. valve member 12 is provided in its side walls with apertures 16 which. when its end is in engagement with the disk or gasket 15 will be. located above. the said end. Vhen, under the pressure ot' inflation, the valveI member 12 is forced downward. the apertures 16 are carried below the shoulder 13 and preferably below the end of the valve-shell. permitting the air to pass out of said apertures into the chamber 4 and through the duct 2 to the tire. For deflating the tire l secure to the bottom ot the valve member lf2 on the' inner side thereof a stem 1T which extends upward through the bore of the tubular shell to the end thereof provided with the nut or :mn-circular portion (l. Bv the use of a suitable implement` as will be understood. the dellating stein 17 may be pressed downward. thereby moving the valve member downward to uncover the apertures lo and permit the'air to tlow in from the tire through said apertures and through the valve-shell to the outer air. [t will bc understood. of course. that the wall of the chamber t docs not closcl)Y embrace the valve member 1:2. but atl'ordsl a suilicicnt space surrounding the valve member to permit thc passage of air through the valve in either direction as abo.'c described. i

l claim:

l. ln a valve mechanism of the class described. a valve comprising a tubular shell adapted to la secured in a casing. a hollow valve member mounted to slide'on the lower end ot' said shell. and having a side wall with an aperture. and a closed end. a gasket supported on said clwcd end, the lower end of said tubular member providing;r a valve seat adapted to form a sealing Contact with said gasket, and means for limiting the opening movement of said valve member when said aperture is beyond the end of said shell to open Communication through the said Vallv of said valve. member and through the end ot' said shell.

2. In a valve mechanism ot' the class described, a valve comprising a tubular shell adapted to be secured in a easing, a hollow valve member slidably secured on the lower end of said shell and having a side wall with an aperture, and ay closed end, a gasket supported on said closed end, the lower end oli' said shell providing a valve-seat adapted to :l'orm a sealing Contact with said gasket7 a deflating stem secured to the closed end of said valve men'xber and extendingr upward through said shell, and means for limiting the opening,- movement oll the said valve member when said apertlufe is beyond the end of Said' shell to open communication through the side wall olC said valve member and through the end ol' said shell.

ln valve merhanism olil the class described, a valve comprising a tubular shell adapted to be secured in a easing and provided near its lower end with an annular shoulder, a hollow valve-member slidably mounted on the lower end oll said shell and having a side wall with an aperture, a closed outer end and a turned-in inner end for engaging said shoulder to limit the opening movement oi said valve-,member when the said aperture is below said shoulder, a gasket supported on said closed end, the lower end of said shell providing a valve-seat adapted to form sealing- Contact with said gasket, and a deflating stem secured to the. clos'cl end of said valve-member and extending upward through said shell. Y

4. 1n a valve mechanism of the class described, a tubular shell adapted to be secured in a easing, a hollow Valve member slidaloly secured on the lower end of said shell, and having a side wall with an aperture, and a closed end, a gasket supported on said Closed end, said tubular shell having an annular shoulder engaging said valve member, the lower end of' said tubular member providing a valve seat adapted t'o" form a sealing contact with said gasket, and means for limiting the opening movement of said valve member when said aperture is beyond said shoulder to open communication through the said wall of said valve member and through the end of said shell.

In testimony whereof, I have hereunto set my hand.
