Description

UNITED STATES PATENT OFFICE.
.ARNO R. 'HUETTIGy OF ERIE, PENNSYLVANIA, ASSIG-NOR TO iAMERICAN METER COM- PANY, F NEW YORK, Y., A CORPORATION 0F DELAW'ARE.
GAS-METER DIAPHRAGM.
Application led August 6, 1926. Serial No. 127,657.
Gas meters are usually formed with operating diaphragms formed of leather. Such leather has been almost universally in use as best adapted for the purpose. With larger' meters diiculty is experienced in obtaining a sufficiently uniform quality of leather in a single hide to form a diaphragm, the leathers used varying in different portions of the hide. This variation in quality gives to the diaphragm a lack of uniformity of movement that is not desirable. I have obviated the difficulty as to lack of equality and made it possible to make the diaphragm of approximately uniform quality throughout by forming it` l5 of a plurality of segments. These segments are formed to give the diaphragm itsrinal form. This, however, has heretofore been done with a single piece for the diaphragm. Features and details of the invention will appear from the specification and claims.
The invention is illustrated in the accompanying drawings as follows Fig. 1 shows an elevation of the diaphragm, .the cover of the-meter case being removed to expose the same. v
Fig. l2 a section on the line 2-2 in Fig.1. Fig. 3 an enlarged section of a part of the diaphragm on the line 2-2 in Fig. 2.
Fig. 4 an elevation of a leather segment of the diaphragm. A
Fig. 5 an elevation of a detached diaphragm.
1 marks the meter case, 2 the covers on the case, and 3 a central partition in the case dividing the same into chambers 4 and 5. Diaphragme 6 and 6a are arranged in the chambers. The diaphragm 6 Vis connected by a `rock arm 7 with a rock arm 8 and the movement of the rock arms is communicated by a link 9 with a crank 10. The crank 10 is mounted on an operating shaft 10Ll and operates the dials 11. A link 12 connects the crank with levers 13-13 which are connected to the diaphragm 6, The upper end of one of the links 13 is connected by a link 15 with the 45 case at 16 and the lower end of the downwardly extending link connected with the case at 17. These parts form no part of the invention but merely indicate the use, or environment.
The diaphragm has a central plate 18 with a Surrounding flange 19. The diaphragm leather 2O has an opening through its center with a turned edge 21 and this is secured around the flange 19 by a Wrapping 22, these 55 parts being properly treated so as to assure a gas-tight joint. The diaphragm leather is formed of a plurality of segments 23. In a quadrilaterally shaped diaphragm, such as shown, four are preferably used and these are o'ined by seams 24 which are arranged to provide a gastight joint and these seams are preferably arranged extending to the points of greatest radial dimension of the free part 0f the diaphragm leather so that the stiffer '65 part of the diaphragm incident to the seam is given the greatest range for movement. The segn'ients are preferably fashioned so that when the diaphragm is completed is assumes the flaring shape with the leather in its natural condition. There this is done the dia` phragm will tend to retain its shape.
What I claim as new is A gas meter diaphragm comprising a central plate; and a leather member secured to the plate and formed of a plurality of segments secured together at their edges, the leather member having some radial dimensions greater than others and the union between the segments being along the radial lines of said greater dimensions.
In testimony whereof I have hereunto set m hand.
