JOHN SGHATT, OF PHILADELPHIA, PENNSYLVANIA, ASSIGNOR TO HIMSELF AN D SAMUEL P. MERVINE, JR, OF SAME PLACE.
Letters Patent No. 66,256, dated July 2, 1867.
IMPROVEMENT IN DRY GAS-METERS.
J "digs fizlgcmrlc taunt tu in flgcse Litters new ant mating part at figs time,
TO ALL WHOM IT MAY cononnn:
Be it known that I, JOHN SCHATT, of the city of Philadelphia, in the State.of Pennsylvania, have invented a new and useful Improvement in the Dry Gas-Meter; and I do hereby declare that the following is a full,
clear, and exact description of the construction and operation of the same, reference being bad to the accompanying drawings, and to the letters of reference marked thereon.
My invention relates to the manner of connecting the leather to the rings of the disks and the diaphragm, which together with the said leather form the measuring-chamber of a dry gas-meter, and consists in attaching the edges of the said leather to the rings respectively by applying and securing a single cord in combination with the side edge of;the leather within a groove, subsequentlyclosed around the edge of the ring, substantially as, hereinafter described. Referring to the drawings- Figural is a vertical diametrical section, and
Figure 2 a transverse section of the rings and the' connecting leather of a'mecsuring-chamber.
Figure 3 being an enlarged section of part of the same.
, Like letters of reference indicating the same parts when in the different figures.
A A are the two rings of a chamber, B the connecting leather, and C the cord; the disks and diaphragm to which the rings are to be soldered, not being necessary to explain the invention, are not shown in the drawing. The rings A each consists of a narrow strip of sheet metal connected together at its ends so as to form a band. One edge a" is then turned outward so as'to form a narrow flange or face for soldering the ring to either the usual disk or diaphragm, as the case may be. Along near theopposite edge of the said ring I thenindent a semicircular groove a', and taking a piece of twine or other cord suitable for the purpose, I confine thereby the edge side'of the usual leather B'firmly down in the said groove 81/, securing the two ends of the said cord 0 together by a hitch or tie, and adjust the wrinkles, of the confined edge side of the leather uniformly around the ring, so as to remove any laps intthe leather under the cord, (see the left-hand side of fig. 1.) I now close the groove 11' over the cord and surrounding leather by running it between the rolling-dies of the well-known closing machine used by tin-workers, and thus producea perfectly gas-tight connection between the edge of the leather B andthe ring A, as represented at a in figs 1, 2, and 3.
Heretofore in the manufacture of dry gas-meters requiring this form of chamber, the leather has been secured to the rings by winding a cord several times tightly around the flat surface of the latter with the side edge of the leather between, but such mode is not only difiicult of execution, but the tension of the cord varies during the service of the meter from hydrometric causes, and consequently the chambers leak or cease to be gas-tight, and are therefore not reliable as measurers of the gas passing through the meter; whereas in my described mode of securing the leather to the rings it will be readily seen that as the cord O and the portionof the leather B around it are enclosed tightly and closely within the metallic case or bead a", moisture cannot reach the interior of the latter, and therefore the juncture will remain perfectly gas1tight and reliable.
Having thus fully described my' improvement in the manufacture of dry gas-meters, what I claim as'my invention, and desire to secnre by Letters Patent, is confined to the following, viz:
I-claim the attaching leather B and the ring A together by means of the single cord C and the groove closed tightly over the said cord and leather, substantially in the manner described and for the purpose specified.
' JOHN SOHATT.
