THE “QUICK AS WINK” COUPLING.
Anything that will help to get water on a fire in its incipiency is a boon to fire departments, and the victims of fires, and if that “first aid” can be made not only to operate quickly, but also to withstand the rough usage and severe strains to which it is necessarily subjected, the boon is still further enhanced. Such double service is rendered by the coupling invented by Joseph S. Blackburn—the “Quick as Wink,” among whose characteristics are the following: It is easily operated by one man; no spanner or other tool is required except a small pocket key for disconnecting: connections and disconnections are made without any loss of time; and there is no delay on account of crossed threads,nor is there any leak,since, the greater the pressure, the greater is the certainty of watertightness. The connection will not let go until opened by the key, and though absolutely watertight, the two parts, as illustrated, swivel upon one another. A quarter turn with the key opens and breaks the connection, and this can be done while the water pressure is on. The coupling is attached to the hose by expanded rings in the usual way and the water-way is smooth and unobstructed. If flattened by any accident, it still works all right—unlike the screw coupling in this respect, and avoids all those delays from battered threads or missing gaskets which are common to screw couplings. Mud, slush, frost, or snow do not affect its action, and even inexperienced persons can operate it quickly and successfully. An illustrated catalogue of The W. J. Clark Company of Salem, Ohio, sole manufacturers of the ‘ Quick as Wink” coupling, just issued, gives full particulars as to prices, etc., together with a long list of testimonials as to its merits—all founded upon three years’ experience of the coupling.
