S SMITH AIR WHISTLE.

UNITED STATES PATENT OFFICE.
SINCLAIR SMI'III, OF LONG ISLAND CITY, NElV YORK.
AI R-WHISTLE.
SPECIFICATION forming part of Letters Patent No. 414,336, dated November 5, 1889.
Application tiled December 20, 1888. Serial No. 294,168. (No model.)
.T0 all whom it may concern:
Be it known that I, SINCLAIR SMITH, of LongIsland City, county of Queens, and State of New York, have invented a new and useful Improvement in Air-IVhistles, of which the following is a specification.
My invention consists in interposing a cylinder fitted with an air-tight piston between the whistle and a motive force-such as steam, gas, air, or other compressed vapor--whereby the lat-ter serves to operate the piston and force air contained in thc cylinder through the whistle to sound it, while the vapor may be returned to a suitable receptacle and again utilized, instead of being discharged into the atmosphere and thereby wasted. In other constructions the motive force passes directly to and through the whistle. Various disadvantages arise from this method of applying the motive force, and among them may be mentioned that of steam condensing in the branch pipe leading to the whistle, and which has to be blown through the same before it can be properly sounded, besides being the cause of much inconvenience7 more particularly when used in small boats and yachts.
In the drawings, Figure 1 is a side elevation, partly in section, of a whistle and its appurtenances constructed according to my invention. Fig. 2 is na transverse section through the line :c Fig. 1; and Fig 3 is a plan of certain parts.
A designates a whistle, which may be of the usual form and construction.
B is a cylinder tted with a piston C,which normally will rest on the bottom thereof. This cylinder is made sufficiently large to furnish the requisite quantity of air to operate the whistle, to which it is connected by a pipe D. The piston O is accurately ground to t the cylinder, and is provided with suitable packing-grooves c c c', which may be packed, if found necessary.
E E are valves of ordinary construction to regulate the iiow of steam or other vapor motive force to and from the cylinder. These valves are respectively connected to the main pipe by two pipes e e', which are coupled to the main pipe by a Y-coupling ci.
F is a supply-pipe connected to the lvalve E, and extends to a source of motive force, such as the steam-chamber of a boiler.
F is an exhaust-pipe connected to the valve E', to convey the mot-ive force after use to a suitable receptacle-such as the condenser of a steam-engine-whereby it may be again utilized.
The valves E l are operated by means of a rock-lever G, mounted on a standard g, secured .to the valve-chests. The extremities of this lever rest loosely on the stems of the valves and are provided with an arm g', to which a wire g2, or other suitable means for rocking the said lever G by hand, is connected.
I'I is a spring which automatically closes the supply-valve E and opens the exhaustvalve E.
The operation of my invention is as fol-- lows: On pulling the wire g2 the supply-valve E is opened and the exhaust-valve E closed, when the motive force enters the cylinder B, raising the piston and forcing the air contained therein through the whistle and sounding it. On releasing the wire g2 the spring H closes the valve E and opens the exhaustvalve E', when the weight of the piston will force the contents of the cylinder below it into a condenser or other suitable receptacle, from which they may be again utilized, and simultaneously therewith the cylinder above the piston will again be filled with air.
My invention is peculiarly adapted for application to naphtha boilers or retorts, as it prevents the escape through the whistle of any explosive gas.
Having now described my invention, what I claim as new, and desire to secure by Letters Patent, is-a 1. The combination of the air-whistle A, supply-pipe F, exhaust-pipe F', valves E E', mechanism, substantially as described, for opening one valve and closing the other simultaneously, and the cylinder B, having an air-tight piston C fitted to slide freely therein, said cylinder being interposed vertically between pipes, the upper one of which communicates with the whistle and the lower one with a coupling c2, uniting pipes c e,which extend from the valves E E', substantially as described.
2. The combination of the air-whistle A and cylinder B, interposed vertically between pipes, the upper one of which communicates IOO with the Whistle and the lower one With a coupling e2, uniting pipes e e', which eXtend from the Valves E E', interposed, respectively, between the pipes F e and F e', each of said Valves Working in separate chests provided?, with inlet and outlet pipes, and each chest Containing a spring tending to Close said valves, the latter being` operated by a roek-4 lever G, fulcrumed between its` ends to a standard g, secured to the Valveeehests and having its extremities resting loosely on the stems of said Valves, the said lever also having an arm g', to which a cord g2 is attached, by which the supply-Valve E is opened and the exhaust-valve E allowed to close, the latter valve being held normally open and the former closed by a spring H, substantially as described.
