- phra'gms have self tensions which had to be subdued by the gas pressure saidgas meters gave-rise to undesirable loss of pressure in the gas conduits leading to burners or' other gas apparatus to be controlled by the metal. The object of the invention, therefore, is to construct a dry gas meter with metallic diaphragms the self tensions of which is compensated, so that any loss of gas pressure is eliminated. With this object in view the invention consists in a dry said chambers being controlled gas meter having three gas measuring chambers formed by the casing of the meter and two bellows therein Eonstructed of metallic diaphragms, the gas inlet and gas outlet to y a suitable valve operated by the intermediary of a crank gear with link'motion connected with the bellows to be inflated by the gas. The bellows are connected by means of said gearing in such a way that the self tensions of the diaphragms of the one bellows in its return stroke into its position of rest are used to subdue the self tensions of the other bellows in its forward stroke, the gas pressure, therefore, having only to surmount the friction of the gearmg. Said gearingconsists of a crank shaft havin \two cranks dislaced to one another a put 90 and two s carried by the bellows. and in connection with the said crank. When the bellows are inflated they rotate the shaft of the gearing in a known. manner so that the control-' ing valve for the, gas distribution into the measuring chambers is set into operation and the counter is rotated. a
In the accompanyingdrawings- Fig. 1 is a vertical section through meter,

' the inner side of the casin 1.
The new meter consists of a casin 1 carvrying the known counter 2, a gas in et nipple 3, a gas outlet nip le 4 and a, distributing valve 5 adapted to e operated by means of a shaft 6 having two cranks 7 and 8 displaced to one anotherabout 90: The cranks are provided with rollers 9 and 10, respectively, adapted to engage slots 11 and 120i Each bellows consists of a series.7
closed by means of a bottom and on the other end it is fastened to a ring 18 fixed to he rings 18 may also be integral wit the casing constructed in two halves connected to one another by means of an outer ring 1, as shown in Fig. 1. The two bellows are placed with their open ends towards one another so that they form anexpansible and collapsible chamber 19. The inner space of the casing 1 is divided by the bellows into two measuring chambers 20 and 21, while the third chamber (19) for the gas to be measured by the meter is formed by the two bellows.
The valve 5 is arranged in a casing 25, which is in open connection with the outlet nipple 4 of the meter. The inlet nipple I communicates with a valve chamber 24 which is located in the inner part of the valve 5. Leading to the gas measuring chambers of the meter conduits 22 are arranged in the valve 5 having a cap 23 by means of which each measuring chamber may beput into communication with the known, so that the operation of the, crank shaft needs not to be described.
As to the movement of the bellows it may be presumed that they take the position shown in Fig. 1, in which the bellows 15 in the chamber 20 is at rest and in which the metallic diaphragms have nose-1f tensions. When gas is admitted to the meter and the crank shaft 6 is rotated about 90 the bellows 15 in returning to its state of rest presses the bellows 16 together. In rotating the shaft further about 90 the bellows 15 is pressed together by the intermediary of the self tensions of the bellows 16 returning in its state of rest. By the next movement of the shaft of about 90 the self tensions of the bellows 15 are used to bring the bellows 16 hits inflated position, and after a further rotation of about 90 of the shaft the inflated bellows 16 returns to its state of rest whereby its self tensions cause the bel- 1. In a dry gas meter, the combination with a casing, of two bellows within said casing, each of said bellows being open at one end and closed at its other end, they two bellows being arranged with their open ends opposite each other and attached to the casing so as to divide the space within the easing into three measuring chambers,
means of said measuring chambers.
2. A dry gas meter as set forth in claim 1, the crank and llnk mechanism comprising two cranks arranged at an angle to each other of substantially ninety de ees, each crank being connected to the be lows by a" slot and link connection.
3. A dry gas meter as set forth in claim 1, the crank and link mechanism comprising two cranks arranged at an angle to each other of substantially ninety degrees, slotted members fixed to the bellows, and rollers carried by the cranks and working in the slots, whereby to reduce the friction between the slotted members and the crank.
4. In a dry gas meter, the combination with a casing, of two metallic bellows within said casing, each of said bellows being open at one end and closed at its other end, the two bellows being arranged with their open ends opposite each other and attached to the easing so as to divide the space within the casing into three measuring chambers, one of said chambers being formed by'the bellows and the portion of the casing walls com-v prised betweensaid open ends, a crank and link mechanism operably interconnecting said bellows so as to transmit the tensions of one bellows to the other as the bellows are alternately expanded and contracted, a distributing valve, and means operablyconnecting the valve to the mechanism for per- 1 mitting the mechanism to rotate the valve.
