Opinion

REED, District Judge.

Interchangeable right and left stop and waste cocks were well known in the plumber’s trade and in common use long before the patent in suit was applied for. In the beginning of the specifications of this patent it is stated:

“This invention relates to interchangeable right and left stop and waste cocks, and it is intended to protect the adjustable stops of said cocks, and to make the connection of the same much more secure.”

After describing the invention and its operation, the specifications continue:

“The operation and the general result above described is substantially the same as in other interchangeable stop and waste cocks, but there is in my device a specific peculiarity which 1 wrill now explain. In other cocks of like character the adjustable stop bearings are held in position by a screw, and in consequence thereof such connections are somewhat insecure. Moreover, the stops are exposed to the accumulation of dirt, and, on account of the customary location of such cocks, such exposure is liable to interfere with the corred: action of the stops. In my device the stops are inclosed by the stop cap itself, and the square hole of the cap fits over the square end of the plug and forms a practically rigid connection. The adjustment of the stops is to an extent of ninety degrees, so that the square bearings of the cap and plug are peculiarly fitted to (.lie purpose. It is obvious, however, that octagon bearings, for instance, would enable the same result to be effected in nearly as [992] desirable manner, so that, in using the word ‘square’ throughout the specification and claim, it is intended to be typical of prismatic as opposed to circular.”

There is but a single claim, and that is for—

“an interchangeable stop and waste cock consisting of a shell haying a waste hole, and a rectangular stop projection 11 formed on its side, a plug having a waste hole and a projecting end square in cross-section, a cap having a square hole in its end adapted to engage the square end of the plug, stop bearings in the cap adapted to entirely inclose and strike the stop projections of the shell, and a handle on the plug outside the cap substantially as set forth.”

Tor convenience of reference a copy of the patent is attached hereto.
