' I Letters Patent No. 109,230, dated Novemberli, 1870.
IMPROVEMENT IN DRY GAS-METERS.
The Schedule referred to in these Letters Patent and making part of the same.
We, GEORGE Lowen and SAMUEL H. common, both of Pit-tsbnrg, Allegheny county, state of Pennsylvnnia, have invented certain Improvements in Dry Gas-Meters, of which the following is a specification.
The invention relates -to providing the dinphrngms with flexible tubes at'thc lowermost part, which com-. municate with chambers or receivers outside of the meter-case, these flexible tubes to be provided,'inside Figure 2 is a, side view of themeter, with the lowersection of the euse, diziphragms h 7:, flexible tubes e e, and condensing-chambers ff; exposed;
' Figure 3 represents the bottomof the meter, showing the situation of the condensing-chambers ff and thumb-screws g g. v
lsignre 4 is a, front view of a dry gas-meter, with all the pin-ts in situ.
.Claim.
' We claim as our invention-.-
The flexible tubes 6 e, communicating between the interior of the dinphrngms h h and condensing-chemher or receivers f. j; substantially asnnd for the purposes described.
