' to provide reasonable piston speed with a fairly high-speed motor. The described construction .also provides for the proper maintenance of the yoke in proper position parallel to the gear wheel without any elabora-te devices for that purpose, this alignment being maintained by the ample bearing faces of washers 47 and 4S at opposite sides of the yokes in .all positions ot' the crank pin.
One or more whistles may be provided, and they may be arranged in any suitable position and properly connected with the cylinders, but conveniently, and preferably in most cases, as in the present embodiment of the invention, the whistles 50 are arranged as units on bases 51 which are connected directly with the outer parts of the cylinders. Speciiically, as here shown, the whistle bases are in the form of hollow nuts with threaded extensions 52, which are screwed into .suitably threaded hol-es 53 in outward portions of the cylinders near the outer ends thereof. The whistle units are of any known or suitable type, and each includes a stein 54 supporting the whistle tube 55 and air nozzles 56 are arranged to direct air jets against the open edge of the tube.
At every inward piston stroke air is drawn passage in the whistle base, or both, and on each outward stroke the valve 15 closes and air is compressed and driven forcibly out, producing a sharp whistle blast which is readily audible in the midst of the other noises, including the noise of battle, and these blasts are rapidly repeated, two blasts occuring with each rotation of gear 40 when two whistles are provided.
The whistle bases may be unscrewed and the whistles enclosed as units within the casing tor shipment, and may be easily reinounted in an obvious way when the apparatus isset up for use.
One or more of the complete appliances may be included in one circuit or a plurality of the appliances mav be play-ed in different circuits, and however, the circuits may be arranged, the alarm is sounded merely by closing the circuit at a suitable switch, which may, if desired, be arranged so that the mot-or runs to sound the alarm for any designated time and is then automatically cut ott; or any other desired control arrangement may be provided.
claim:
A unitary, self-contained signal or alarm comprising a. housing including base and cover portions, an electric motor secured to the base within the housing, opposite cyliir ders on a common axis formed as parts ot the base section oit the casing, heads secured on outward ends of the cylinders, check valves cooperating with valve holes in the heads, a piston in each cylinder, a gear rotatably mounted in the casing, a pinion on the motor shaft engaging the gear, means including a crank connecting the gear to the piston, and a whistle unit mounted on each cylinder and in communication with the interior thereof.
Signed at New York city, in the county of New York and State of New York this 21st day of June A. D. 1923.
