ERNST M. VON KRUSENSTJERNA, 0F ST. PAUL, MINNESOTA.
DETACHABLE DIAPI-IRAGM FOR GAS-METERS.
Specification of Letters Patent.
Patented Aug. 2d, 1917.
Application led September 25, 1915. Serial No. 52,749.
To all 'whom t may concern:
Be it known that I, ERNST M. von KRU- snNsTJnRNA, a citizen of the United States, residing at St. Paul, in the county of Ramsey, State of Minnesota, have invented certain new and useful Improvements in Detachable Diaphragme for Gras-Meters; and I do hereby declare the following to be a full, clear, and exact description oi. the invention, such as will enable others skilled in the art to which it appertains to make and use the same.
This invention relates to a detachable diaphragm for a gas meter.
An object of the invention resides in the provision of a device which may be readily installed in a meter without necessitating the use of solder at a plurality of points.
A further object of the invention resides in so constructing the device that it may be installed in a very short time and by an inexperienced person.
A further object of the invention resides in so constructing the device that it will be adjustable and consequently will give a more steady flow of gas.
A still further obj ect of the invention resides in the provision of a device of the character described which may be installed in gas meters of the types used at the present time.
With these and other objects in view such as will appear as my description progresses, my invention comprises the combination and arrangement of parts as set forth in and falling within the scope of the appended claim.
In the drawing Figure 1 is a front elevation of my device showing the same placed in a meter, the meter being shown in section.
Fig. 2 is an enlarged sectional view of the device taken at right angles to the planes of the disks.
Fig. 3 is a plan view,
Fig. 4 is a detail showing the manner of securing the leather strip to the disks, and
Fig. 5 is a Jragmental detail.
Referring to the drawings by reference characters', like parts are indicated by like characters throughout the several views.
I have illustrated a portion of the casing 1 of a gas meter which is provided with a partition 2, the meter being of the usual type. Secured to the partition 2 by means of solder is a channel member 3 which is provided with an externally threaded shank 1. Detachably mounted on this externally threaded shank L.tot the channel member is a metallic disk 5 which has an internally threaded socket 6 with which the shank i is engaged. The joint between the disk 5 and the channel member 3 is made gas-tight by a gasket 7. Secured to the periphery of the disk 5 is a strip of flexible material 8 which is secured to a second disk 9. The edges of these disks are bent over to form channels 10 while the edges of the strip 8 are turned back upon themselves and stitched. Draw strings 11 are mounted in the turned back portions of the strip 8 and are pulled so that the said strip is slightly gathered at its edges. These turned back portions of the strip are located in the channels 10 of the disks and these channels are crimped to maintain the strip in place and form a gas-tight joint. The turned back portions of the strip also act to reinforce the strip at the points of connection to the disks.
Secured to the disk 9 is a stud 12 on which is rotatably mounted a pair of arms 13 on which guide eyes 14: are formed. These eyes are adapted to receive the guide wires 15 and are adjustable so as to be accommodated to wires of various lengths. A pair of brackets 16 is mounted on the stud 12 and said brackets are adjustable toward and away from each other, this adjustment being possible because of the fact that the brackets are provided with slots 17 through which the stud 12 extends. The end of the stud 12 is threaded and a nut 18 is engaged with this threaded end to clamp the arms 13 and the brackets 16 in their proper positions. Mounted in the brackets 16 is a rock shaft 19 on which the flag 20 is mounted, which Hag is supported on the usual flag wire 21. The brackets 16 are adjustable so as to accommodate flags of various widths.
It will thus be seen that after the channel 3 has once been soldered in place in the casing of the meter, the diaphragm may be readily put in place without necessitating any Jfurther soldering since the diaphragm is secured to the channel by screw threads and the brackets and guide eyes are secured to one of the disks by a nut.
It will thus be seen that I have provided a diaphragm which may be very readily installed and one which may be installed by a person other than an expert. Furthermore, I have so constructed the device that it may be installed in meters of various sizes and types as the parts are adjustable.
While I have illustrated and described a particular embodiment 'of my invention it has merely been for the sake of convenience and I do not Wish to be limited to that particular embodiment as it is obvious that numerous changes may be made in the details of construction Without departing from the spirit of the invention or exceeding the scope of the claim.
Vhat I claim is In a diaphragm construction for gas meters, the combination with a channel member, of a disk removably carried by the channel member, a second disk, a strip of eXible material uniting said disks along their edges,
and freely suspending the second disk, a stud projecting from the outer face of the second disk, oppositely extending guide arms mounted upon the stud, a pair of radially adjustable brackets also mounted upon the stud and adapted to removably 'receive the rock shaft of the usual meter flag, and a head threaded on the stud for securing said guide arms and said brackets in their relatively adjusted positions. i
In testimony whereof, Iv am); my signature, in the presence of two Witnesses.
