GAS-METER FRAME.

SPECIFICATION forming part of Letters Patent No. 490,149, dated January 17, 1893. Application tiled .Tune 15, 1892. Serial No. 436,819. (No model.)

To all whom, it 'may connerie:

Be it known that I, HUGH LOGUE, a citizen of the United States, and a resident of Philadelphia, Pennsylvania, have invented certain Improvements in Meter-Frames,ot which the following is a speciiication.

The object of my invention is to make the diaphragm frame of gas meters of a single sheet of metal properly stamped up, thus avoiding the corner joints of the ordinary frame.

In the accompany-ing drawings:-Irigure l, is a perspective view of the two trames detached, between which is clamped the leather diaphragm; Fig. 2, illustrates the top frame prior to being bent up and flanged; Fig. 3 is a plan View of the top frame flanged; Fig. 4, is a plan View of the lower frame out prior to being flanged; Fig. 5, is a view of the lower frame flanged; and Fig. 6, is a sectional perspeetive view through both frames with the' leather between them.

The usual method of making the trames for meter diaphragme has been to make each f rame of four stri ps of metal, soldered together at the ends so as to form a quadrangular trame, but these are not only costly to manufacture owing to the time and care required in soldering the joints, but also on account of the difficulty of making a gas-proof joint between the frames and the leather, as the overlapping corners necessitate careful filling and packing in order to prevent leakage, but by stamping the frames out of a single sheet of metal, the overlapping joints are dispensed with, and when the leather is once clamped down upon the frame, it will be perfectly even and gas-proof avoiding the necessity of packing.

The underframe A has adeep outside ilange af, and a shallow inside llange b. This inner llange is turned outward and lapped over the outer face of the frame A so as to present a smooth edge for the leather. The outside flange is of a sufficient height to lap over the -frame B and the leather so as to hold the trame I3 firmly upon the leather making a gas-proof joint. The frame B is also provided with an internal ilange CZ which is turned over upon theoutside ot' the frame B presenting a smooth edge for the leather, the same as the flange b of the frame A.

The plates cut from the interior of a flat diaphragm meter are preferably cut and the frames used as shields for the leather, as

shown in Figs. 3 and 5, thus all the metal is utilized in the manufacture.

The shields are cut and the edges folded over as shown in the ligures, the shields being placed on both sides of the leather and secured thereto in any suitable manner, as shown in Fig. 6.

I claim as my inventionzm l. The combination in a meter diaphragm, of the quadrangular open frame A made from a single sheet of metal, having an external clamping tiange, and an internal flange, a quadrangular frame B also made from a single piece of metal, and having an internal flange, with leather or equivalent material mounted between the two frames, the clamping ange of the frame A being turned down over the frame B, substantially as described.

2. The combination in a meter diaphragm, of the quadrangular internally flanged frames A and B each made from a single sheet "t metal, one frame having an external clamping flange adapted to pass over the other, two sets of triangular ilanged shields made from the metal out from the frames A and B, with leather clamped between the two sets of quadrangular shields, the internal flanges of the frames A and B, and the ilanges of the triangular shields being bent outward so as to form smooth edges for the leather, thus preventing the cutting of the said leather, substantiallv as described.

In testimony whereof I have signed my name to this specification in the presence of two subscribing Witnesses.

HUGH LOGUE.
