VALVE.
Application'flled June- 29, 1926, Serial m5. 119,480, and in Germany. July 7, 1925. i
This invention relates to valves, and more particularly to that type of valve, employed in conjunction with dry gas meters.
It is sometimes usual, for example in the case of gas meters, to employ valves of the flat type, which consist of a gastight .material drawn over a resilient wire ring (spring ring). Such valves, particularly iflight materials are employed 'in their construction, show a great tendency to warp or become deformed, i. 9., do not remain flat and therefore give rise to leakage, the force provided not being sufficient to press the same tightly on to the seating.
The object ofthe present invention is to overcome thissaid drawback, and to this end the material is stretched over ashort metal cylinder, and is held by a spring ring of the type already in use. lVhilst the metal cylinder provides for rigidity or stiffness of the valve and prevents the same from warping, the spring ring causes .thematerial 'to be quite evenly tensioned even if,
after a relatively long period of use, the tensioned material, due to the frequent striking of the valve against the seating, should become stretched or wrinkles be formed in the same.
According to' one form of embodiment two layers of material are laid over the cylinder, the one at the top and the other at the bottom, and sewn togetherv along their "peripheri'es, an expansible and contractible spring ring having previously been intermetal cylinder.-
' metal cylinder, and an expansibl'e and con'. 40
1 cylinder in such manner that the breaks in posed between this I According to a ment, a transverse strip is cut away from the tractlble spring ring inserted into-the metal the cylinder 'and the spring ring come to rest at different points. The gastight'mw terial, with the" metal cylinder pressed against it is then sewn as in the; case of the first form of embodiment, or is drawn over the metal cylinder from the o'ne'side' and held on the other side by means-of threads.
The latter method is applicable only ,to simple valves, whilst double or twin valves puckers or peripheral seam and the furtherform "of embodithe cylinder and ring.
[cylinder and ring,
requireto have the material sewn along the periphery.
' The invention is illustrated by way of v example in the accompanying drawing, in which Fig. 1 shows in plan and section the first form of embodiment referred to.
Fig. 2'isa similar View of the second form x of embodiment.
lVith reference to the drawing, 1 is the gastight'material and 3 the hollow metal! cylinder, the latter in the one case having an inwardly disposed annular groove and in the othercase an outwardly disposed annular groove 2. 4 shows the point where the two layers of material arejoined along their periphery, and 5 is the spring ring, which in the one case encircles the metal cylinder,
7 and in the other case is disposed within the 1n position.
' 2. A valve comprising a hollow metal cylinder having an annular groove, an expanslble and contractible sprlng ring circumferentially of said cylinder and disposed in saidgroove, a layer of gasti ht material covering the top of the cylin er, and a layer of gast-ight material covering the bottom of the cylinder, said layers joined together along their peripheries to 'completelyenclo se r 3. A'valve comprising a hollow metal c'ylinder, said cylinder having a transverse strip cut therefrom, a split expansibl e and con-.
tractible spring ring disposed within the said cylinder in such manner that the break in' the said cylinder and the break in the ring aredisposed at'diiferent points, and
gastight material completely enclosing the In testimony whereof I have afli'xed my signature.
