I Application filed March 13. 1907. Serial No. 362236.
To all 'whom it may concern:
Be it known that we, THOMAS HENNrNG, a subject of the King of the United Kingdom of Great Britain and Ireland, and CHARLES E. HENNING and WILLIAM J. HENNING, citizens of the United States, residing at Pasadena, in the county of Los Angeles and State of California, have invented new and useful Improvements in Gas-Meters, of which the following is a specification.
This invention relates to type wherein a plurality o diaphragms actuated by the gas pressure operate sequentially on crank means to producemotion of the dial and valve means are provided controlled by such motion to give the successive operation of the dia hragms.
An object o this invention is to improve the general construction of such meters with a view to facilitating the construction7 assemblage and adjustment thereof.
A further object of the invention is to r0- vide improved means for seeming in p ace the movable'. diaphragm of the pressure chambers. Y
Another object of the invention is to providef'niproved means for adjusting the operating connection to the crank shaft.
' Another object of the invention is to -provide means for laccurately adjusting the crank or tangent devices for connecting-motion tothe valve means.
Another object of the invention is to provide improved-means for securing the dial mechanism in place in such manner that it can readily be removed and replaced.
' In the accompanying drawings :'#Figure 1 is a horizontal section of the meter on the line :c1-acl in Fig. 3. Fig. 2 is a horizontal section on line 2-ac2 in Fig. 3. vertical section on line ac3-? in Fig. 1. Fig. 4 is a verticalsection on line, L-* in Fig. 1. Fig.
with the dialin place. lihg. 6 is a section of an adjustable crank or tangent means for operating the valve for the pressure operated means. Fig. 7 is an axial section of the valve.
The meter comprises a case 1 formed preferably as a cylindrical shell of sheet metal having itsA ends closed by removable cap-i "`ks or plates 2. The space within the shell '.s divided into three pressure chambers by two diaphragm members 3, 4, which are conas meters of the 5 is a front elevation of the dial receivingl prtion of the case,
nected to the walls of the case by flexible fabric means indicated at 5 fastened to said dialphragms and detachably secured to the wa the peripheral portions of said iiexible means into grooves 7 inthe case. Said expansion -rings are split so that, when they are brought into osition, they can be expandedl to bmd the liexible means firmly in place and can then be secured by solder indicated at 8.
A bail or swinging member 11 is pivoted at each side of the ease and engages within slotted lugs 13 on the diaphragm to guide the diaphragm in its movement, so that it will have a parallel in and out motion. f
A shaft 9 is journaled in bearing 10 in the case and is connectedto the respective dia-v phragms 3, 4 by connecting means herein-y after described.' An arm 12 is pivoted at each side of the case and extends inwardly to the mid width of the case and then upwardly-to form a pivot portion whichr is pivoted iii brackets 14 on the outer side of the corresponding diaphragm. A link 15 is piv- Otegi. on" such pivot portion of one of said arms and is ivotally connected at its other end to a cran 16 on the shaft9 aforesaid. A link 17 is similarly pivoted on the pivot portion of the other arm 12 and is pivoted at its other end to a block 18 slidably mounted in a guide 19 formed inan arm 2O rigidly connected tothe said crank 16. A screw 21 working in said arm 2Q serves to adjust said block in either direction in said guide. The end of said screw is provided with operating means such as a iiattened portion 22, and holes 23 are provided in opposite sides of the case, saifd holes being normally closed -by plugs 24, and being so located 'that when the said plugs are removed the said adjusting meansis directly in the line of vision between the two holes and can be both inspected and /adjusted from the outside of the case without o ening up the case 'or removing the dia'- p rag-ms, a tool indicated in dotted lines at -25 being inserted to turn the screw 2l..
A sheet metal tubular case portion 27 eX- tends upwardly from the top of the case 1 and is formed with a flat floor 28 and with a central valve seat portion 29 on the upper surface of which travels the valve 30, -said valve being formed as a disk. An inlet pipe' 26 leads downwardly alongsidethesefextension 27, and communicates with a riser of the case by expansion rings 6 pressingv entende np above-.the door end openn'into theehamher above the valve, so ftnnt'tlic gas passing in through this inlet impimms downwardly on the verve. Said valve t neet portion ."Qie formed with a central por #tion 3 1 andfwith' three` outer openings 32,
'f3- arranged eroun'd the central'opening. "lllefccntral opening communicates-by a 'duct 735 to an outlet pipeortnbe 36 and'jtwo of the Iter openings communicate bydnct, 37 .with

A glass plate 70 is placed in 75 box- 39 being-su ported by corner-pms ,71 end heldin by t cover box 67.' 1 Thegas enters through passage 26v and posses upward through vthe-pasea e 38. into the valve chamber, beingthus de ivered to the upper part'of thechamber in an upward direction so that it cornes down on top of the valve and there is no tendencvto lift the valve by the gcs iiow. From this valve, it passes down through one ofthe ports, say-34, to say the middle pressure chamber in the meter, thecrank connections to the shaft 9 being such that in .this position in Fig. 1
`there is a differential action. on the shaft,
tending to rotatethe shaft, and suchrota 90 tion the valve is shifted successively to the dtlerent ports, opening communication to .the successive pressure chambers so as to :always produce a rotative force,l on the shaft.
The resulting rotation is communicated to the dial through the meml'oersA 54,; 57, etc. lt will be noted that the' fastening screw 69 for the dial cover is ori/the inside of the case, so that it is protected or sealed against tamthe top of the case. 'Saidclosure plate being' generally soldered. in placeit is therefore 1possible for anyone to tamper with the .l ..105 1.
