DEVICE FOR SUPPORTING FLUID-CONTROL AIPARATUS.

i Specification of Letters Patent.

Patented Jury a, 1916.

Original application led January 21, 1913, Serial No. 743,347. Divided and this application led July 7, 191.4.. Serial No. 849,439.

To all whom it may Concern Be it known that I, Hennen Crimean-iu, a citizen of the United States, residing at Edgewood Park, in the county of Allegheny and State of Pennsylvania, have invented certain new and useful Improvements in Devices for Supporting Fluid-Control Apparatus, of which the following is a specification.

This invention is a division of my `copending application` Serial No. A33-t7, filed January 21, 1913, and relates to an improved device for removably supporting check valves and similar control apparatus for controlling the flow of fluid through conduits, etc.; and it has for its primary ohject the provision of an improved supporting means which is det'achably mounted so that it can be readily removed together with the fluid control device.

The foregoing, together with such other objects as may hereinafter appear or are incident to my invention, I obtain by means of a construction illustrated in preferred form in the accompanying drawings wherein I have shown my improvement applied to a metering device.

Of the drawings, Figure 1 is a longitudinal section through a casing in which my invention is embodied; Fig. 2 is a similar section with the parts shown in a different position; and Fig. 3 is a plan view of Fig. 1 with the top plate and the positive, or normal flow meter, removed.

Referring to the drawings, 3 is a casing in which the fluid control device is mounted. The casing is provided with an inlet opening 4 and an outlet opening 5, the casing being placed in the main (not shown) so that the ports are in the line of iow through the main. Adjacent to the inlet opening, the casing 3 is provided with a seat 6a on which a sleeve 6 is mounted, said sleeve being detachably held in position by means of screws 6b or other suitable means. The upper part of the casing is enlarged to form a chamber C, this chamber being closed by means of a removable cover plate 3a. The sleeve 6, at its inner end, is provided with a sloping valve seat 7 against which the disk 7a of the swinging flow control device A `(which in the present showing is a normal flow meter) is adapted to take. The disk 7a is pivotally leading to the normal flow meter is held in open positionrso that the iow takes place through the normal flow meter. When there is a heavy draft-as that, for example, which takes place in cases of fire-the valve disk 7iL is unseated and assumes the position ;indicated in Fig. 2, the normal flow meter then lying in the chamber C of the casing 3. The valve disk 16 automatically closes when the disk is unseated, and no flow takes pla-ce through the normal flow meter. In cases of back pressure, the disk 7a acts as a check valve. Y

For measuring abnormal or heavy flows, I have provided a proportional flow meter B which is mounted in the apertured portion 9 formed in the upper part of the sleeve 6, said proportional flow meter being detachably fastened in any preferred manner to the flanges 10. The proportional flow meter communicates with a port 30 which is formed in the casing 6, and which opens in the face of the valve seat 7 in position to be covered by the valve disk 7a. A tongue or nose 33 is detachably secured to the valve disk 7 a and normally lies in the port 30, said nose being tapered so as to automatically proportion the opening of the port 30 to the main opening which is formed when the valve disk 7 a unseats.

The indicators for the normal flow and proportional flow meters, respectively numbered 20 and 31, are arranged on the exterior of the casing 3, said indicators being operated by any preferredform of` actuating means D and E connected to the meters. When it is desired to remove, inspect, repair or replace the fluid control devices, the only steps necessary are to remove the cap or cover plate 3a, disconnect the actuating means D and E, and take out the screws 6b; and when thishas been done, the sleeve 6 and all of the parts that it carries can be removed intact. It will also be seen that this arrangement makes it possible to assemble all the partsvand insert them bodily in the casing. The construction is also such that if desired, either' the normal flow meter or the proportional flow meter can be removed independently of one another'. In case it is desired to detach the normal flow meter, the plates 2l are removed; and in case it is'desired to detach the proportional flow meter, the screws 29 are removed.

It will be clear that the arrangement is applicable to a variety of different forms of fluid control apparatus, and I do not intend to limit the invention to the application to metering devices which are shown in the drawings.

A particular advantage incident to my invention resides in the fact that the sleeve offers no obstruction to the passage of fluid, while at the same time ready detachment is possible.

l. In a device of the character described the combination of a casing provided with a seat, a sleeve resting in said seat, said sleeve having' an attaching flange and being Copies of this patent may be obtained'for ive cents each, by addressing the Commissioner of Patents,

provided with a fluid control device adapted to control the flow therethrough, and fastoning screws passing through saidflange and into the ca sing, whereby the sleeve and the fluid control device may be bodily removed from said casing.

2. In a device of the character described the combination of an open-ended casing havinga seat adjacent to one opening, a sleeve resting.,r onl said seat andprovided with a fluid control device, and means fordetachably securing the sleeve in position, said casing being provided with a detachable cover for the withdrawal of the sleeve together with its fluid. control device, there being substantially no obstruction inthe chamber of the casing between the sleeve andthe cover whereby the sleeve may he lifted substantially directly out of the casingn In testimony' whereof I have hereunto signed my name in the presence of the two subscribed witnesses.
