Abstract
A device for recording the flow rate through a flow meter over a period of time is provided for use in conjunction with a flow meter having a rotatable member, the rotational position of which is indicative of the fluid flow rate through the flow meter. The recording device comprises a housing in which a recording medium is mounted and rotatably driven at a predetermined. rate. An elongated scribe arm is pivotally secured at one end to the housing and, at its other end, has a writing instrument which engages the writing medium and produces a visible mark thereon. Similarly, an elongated actuating arm has an axle which is pivotally mounted to the housing and this axle in turn is connected to the flow meter rotatable member. The actuating arm and scribe arm are in turn connected together by a connecting arm which is pivotally connected to the actuating arm at one end and pivotally connected to the scribe arm at its other end. Moreover, the pivotal connection between the connecting arm and both the scribe arm and the actuating arm are radially spaced from their respective pivotal mounting points so that pivotal movement of the actuating arm causes a like and proportional pivotal action of the scribe arm.

Important Notes on Latency of Status data
Please note there is up to 60 days of latency in this Status indicator for certain status conditions. You can obtain up-to-date Status indicator readings by ordering PAIR for the file.
An application with the status "Published" (which means it is pending) may be recently abandoned, but not yet updated to reflect its abandoned status. However, an application filed less than one year ago is unlikely to be abandoned.
A patent with the status "Granted" may be recently expired, but not yet updated to reflect its expired status. However, it is highly unlikely a patent less than 3.5 years old would be expired.
An application with the status "Abandoned" is almost always current, but there is a small chance it was recently revived and the status not yet updated.
Important Note on Priority Date data
This priority date is an estimated earliest priority date and is purely an estimation. This date should not be taken as legal conclusion. No representations are made as to the accuracy of the date listed. Please consult a legal professional before relying on this date.
