SPECIFICATION forming pari; of Letters Patent No.. 312,106, dated February 10, 182..

Appficaticn tiled March 18,1884. (No model.)

To all whom, it may concern.:

Be it known that I, Gi's'rav FAJEN, ot' Milwaukee, in the county of h/Iilwaukee, and in the State of Viseonsin, have invented certain new and uselul Improvements in Gas-Meters; and I do hereby declare that the following` is a full, clear, and exact description thereof.

My invention relates to water and gas meters, and will be fully described hereinafter.

In the drawings, Figure l is an elevation of l my device with one side of the casing removed. Fig. 2 is a vertical section ot'the same on line x x, Fig. 8; and Fig. 3 is a vertical section on line y y, Fig. l. i

A is the casing ot my meter, which is preferably square.

B is a grooved plate or way that forms a half-ellipse and extends from one edge of the case to the other onits inside. To the edges and ends of the groovcd side of this plate or way B is secured a strip of leather or other ends being hermetically sealed, and into the plate or way, between it and the stri p C, a pipe, D, leads at one end, and" rather pipe, D', at the other, so that air or futher. iluid to get from one of these pipes tsltthe other must pass under the strip C.

E is a wheel that is provided with spokes E E E E', the endsof which are bifnrcated to receive rollers F, the peripheries of which correspond in contourite 'the contour ot' the plate or way B. The arms or spokes of the wheel may be screw-threaded to receive nuts a, by which the wheel is balanced to give it an even rotation, and the shaft l of this wheel is connected in any manner with a registering device.

The operation of my meter is as follows: When gas or water is let in through one of the pipes, it infiates the strip C, and causes it to bulge and revolve the wheel E by wedging upon the nearest roller of the arm that rests upon it, and each of the rollers is acted upon in succession as the gas passes through, giving the wheel a constant rotation while the'gas is being consumed, and as the strip :is collapsed as often as it is inflated, and vice versa. there is no chance for it to either stretch or shrink.

Having thus fully described my invention,

what I claim as new, and desire to secure by Let-ters Patent, is-

l. In. a meter, the combination, with a grooved semicircular plate and a flexible strip, the two forming together a curved passageway the outer wall of which is inflexible, while the inner wall-is yielding, of a' wheel, the spokes ot' which carry at their free ends rollers the contour ot' which is convex, corresponding to the concave contour of the inflexible wall ot' the passage-way, substantially as set forth.

2. In a meter, the combination ot the case A, pipes D D', curved and grooved rigid plate B, iiexlble strip G, secured to plate B, and forming therewith a huid-tight passage, and the wheel E, having arms E and rollers F, substantially as set forth.

3. In a meter, the combination, with the Huid-passage B C, ot' the wheel E, having shalt d, screwthreaded arms E', and rollers F, and balancing-nuts (1, adjustable upon the screw-threaded arms, substantially as set forth.

In testimony that I claim the foregoing I have hereunto set my hand, at Milwaukee, in the county of Milwaukee and State of /Viscousin, in the presence ot' two witnesses.
