Description

UNITED STATES PATENT OFFICE PIERRE A. GHAMBEAUX; OF PARIS; FRANCE.
IMPFlCVEMENT IN APPARATUS OR COCKS WITH SAFETY-PLUGS.
Specication forming part of Letters Patent No. 146,045, dated December 30, 1873; application tiled February 28, 1873.
To all whom fit may concern:
\ Be it known thatl, PIERRE AUGUSTE CHAM- BEAUX, of Paris, in the Department ofthe Seine and Republic of France have invented an Improvedv Apparatus or (lock with Safetyllug for Preventing Fraud in the Consumption of L'ightingras7 of which the following is a specification:
My invention relates to the combination of the plug with the body of a oook in such a manner that While the plug may be Withdrawn from its seat for inspection and cleaning, it cannot be Wholly removed and another plug substituted Without destroying some portion of the apparatus; the object of my invention being to prevent the fraud of obtaining gas before it has passed through the meter by means of a union With plug in the oook on the pipe leading to the meter and another in the cook on the pipe leading from the meter.
Figure 1 is a front elevation of an arrangement by which the above-mentioned fraud may be practiced. Fig. 2 is a side elevation of a cock embodying my invention, and Fig. 3 is a side elevation of another cock also embodying my invention.
A, Fig. 1, is the cock tted by gas company; B; the cock fitted by the consumer; C, the union with plugs c c, substituted in lieu of the ordinary plugs. By this arrangement no gas is passed through the meter; and it will be evident that the consumer can Withdrawr these plugs7 which divert the gas from its proper course, and at a moments notice replace the original ones, permitting the gas to follow its proper course through the meter. By adopt ing this plan a fraudulent consumer need only pay the company for such quantity of gas as he may think sufficient to prevent his fraud becoming manifest.
D7 Figs. 2 and 3, is a plug embodyingwmy invention; E,.rod or screw, of one piece with the plug, and having a shoulder, F7 riveted or brazed to its end7 to serve as a stop. As this rod or screw E might be, in some cases, inconvenient, I substitute the ring G, Fig. 2, havin g a chain or link7 H, permanently fixed to it, this chain carr yin gaknob or button, I, to form a stop. It will be evident that this plug D can be easily Withdrawn from its seat until the shoulder F on the knob I comes against the body of the cock, but cannot be Wholly removed Without breaking off the shoulder'or knob.
I give preference to the combination illustrat-ed in Fig. 2; but the modication thereof (shown in Fig. 3) may be found more suitable; but
I claim as my invention- The combination, with the plug D, of the ring Gr, chain H; and knob I, substantially as described7 and for the purposes set forth.
lA. CHAMBEAUX.
