SIGNALING APPARATUS.

Specification of Letters Patent. Patented Sept; 4,1917.

Application fue@ February 2e, 1910.l serial No. 546,093..

To ally/whom t may concern.'

Be it known that I, HENRY R. WORTHING- TON, a citizen of the United States, residing at Dunnfield, in the county of Warren and lState of New Jersey, have invented certain new and useful Improvements in Signaling Apparatus, of which the following is a specification. d,

. My invention relates to that class rof apparatus which is employed at sea and at signaling stations and light houses for the purpose of communicating information to others in the vicinity. y

One of the objects of my invention is to providemeans which in times of fog, rain or snow, will enable officers in command of ships to give definite information to every one in their vicinity as to the position of their ships and the direction in which they are moving. Although my invention is adapted to such use, it is equally as well adapted for use in connection with light houses and signaling stations and at all places where, in times of fog and under conditions when the ordinary signal light cannot be distinguished, it is important to communicate information to others in the vicinity. y

At such times it is theusual practice on board of vessels, toblow stationary steam whistles and fog horns at frequent intervals for the purpose of advising approaching ships as far as possible of their location. But in the absence of Vany knowledge of the direction in which the approaching ships are proceeding, collisions frequently ensue.

By means of my inventiony these difficulties are overcome and the officers of the two ships equipped with apparatus embodying the principles of my invention may be promptly advised, if the two ships approach within signaling distance of each other, as to the relative directions in which the respective ships are moving and where they are located with respect to each other, thus enabling the courses to be changed to avoid collision. And under similar conditions of weather, a light house equipped with a signaling device embodying my invention can communicate its exact location with respect to that ships location.

Another object of the inventionl will appear hereinafter, the novel combinationsof elements being set forth in the appended claims.

Referring to the accompanying drawing,

The ligure is a plan view,`partly diagrammatical, of apparatus embodying ymy invention.

I prefer to mount in the bow of each ship a transmitting device comprising a whistle in a megaphone, and comprising also mechanism for oscillating the megaphone-across the bow of the ship through about 180 degrees and intermittently operating `the whistle. It should be understood that the megaphone, if desired, could be arranged to revolve on a given axis instead of to oscillate. In the form of transmitting' apparatus shown in the drawing, onabase plate or support 1 are mounted alliof the parts except the battery 2 and the manual switch 3 which may be .located wherever desired.

For instance, theswitch 3 may be placed in the pilot house or on the bridge.

1A smallrelectric motor 4 which in this instance is controlled by the switch 5 and the rheostat 6. is connected by the shaft 7 and lthe worm 8 to the gear wheel 9 which is rotatably connected to the base plate in a hori- Zontal position. At 10, near the periphery of the gear 9, is connected a pitman or link 11, the other end lof which is connected at 12 to the gear 13, which in turn meshes with the gear 14. Connected with the gear 14 so as to move therewith, is a megaphone 15 containing at its inner end a whistle 16` which lmay be an electrically-operated air whistle,

trolled 'by an electro-magnet 22.V .1

Connected to the gear. 9 so4 astorrotate therewith, is a pinion 30, whichl meshes with a comparatively large gear 29. At 27` is an electric switch which is normally open but may be closed by the cam 28 when the gear 29 moves to a predetermined position. The speed of the motor 4 and the proportions of the worm 8 and the gears 9, 30 and 29may be such that the gear`29 will rotate once in approximately one minute, and the cam f28 may be of such length that the switch 27 will or a steam whistle,the valve of which is`conbe closed for about five seconds invevery mins ute. The number of times these signals should be blown in any unit of time would be a matter of maritime regulation.

It should be noted that in this instance the circuits and connections controlled` bythe switch 27 are such that when the lever 19 is on contact 31 and theswitchQ? is closed by the cam 28, the circuit will be completed through the electrically-'operated `whistle or through the magnetQQ controllingthe valve of a stea'niori'air whistle.` This circuit .may

'In' 'such case, the whistle would 'be blown each vtime the megaphoiie moved. across the.
