CODE SIGNALING DEVICE.

SPECIFICATION forming part of Letters Patent N o. 541,505, dated June 25, 1895.

Application filed July 2, 1894. Serial No. 516,261. (No model.)

To a/ZZ whom t may concern:

Be it known that I, WILLIAM RYMER, a citizen of the United States, residing at Detroit, county of Vayne, State of Michigan, have invented a certain new and useful Improvement in Gode Signaling Devices; and I declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to whichit appertains to make and use the same, reference being had to the accompanying drawings, which form a part of this specification.

My invention has for its object -a code4 signaling device for various uses, as for a fog signal, for example, and it cons-ists of the construction, combination and arrangement ot devices hereinafter specified and claimed, and illustrated in the accompanying drawings, in which- Figure lis aplan and diagram view illustrating my invention. Fig. 2 is a section on the lineV 2 2, Fig. 1. l Fig. 3 is a side elevation.Y Fig. 4 is a section on the line 44, Fig. 2. a detail view in perspective of one of the contact-plates. Fig. 6 is a view of such a plate in plan, showing also the contact-spring.

My signaling device is more particularly designed for use in connection with a steam or similar whistle, the signals to be given being controlled by electricity, to give the signals required by any given code, automatically, while at the same time the device may be operated by hand if desired.

Hitherto it has been considered a very desirable thing to accomplish, to provide means 'whereby a code of marine signals could be adopted and carried into effect, for example, by vessel men, by which boats approaching one another in a fog, could indicate in what direction they were steering. At present, in a fog the signals given in passing do not indicate in which direction a boat giving its signal may be going.

My invention is adapted among other uses to which it may be applied to enable a given code to be followed which shall indicate the direction of the course of any given vessel sounding a signal. By my improved device any code of signals by a steam or similar Whistle can be sounded, as may be required. I carry out my invention as follows: A represents any steam whistle apparatus.

'controlling valve A2.

Fig. 5 is A is the steam pipe leading to the whistle mechanism, and A2 is the whistle controlling valve provided with an operating lever. This mechanism may be constructed in any ordinary manner.

To control the valve A2, my invention contemplates the provision of a cylinder B provided With a piston, shown in dotted lines at B Fig. 3, the piston rod B2 being connected with the operating lever of the valve A2.

B3 is a steam inlet pipe leading into the cylinder B above the piston, and B4 is an exhaust pipe communicating with the base of said cylinder. It will ,be lapparent that the movement of the piston B operates the whistle To control the inlet ot' steam through the pipe B3 into the cylinder B, I provide a differential piston C in a cylinder C', the lower head c of the piston vbeing of smaller dimensions than the upper head c. C2 is a steam inlet pipe openinginto the cylinder O between the heads of the'difterential piston, the pipe C2 admitting steam at boiler pressure between said heads. Obviously the upper head being larger, the steam admitted through the pipe C2 will exert an increased pressure upon the head c over that exerted upon the head 0.

The heads of the piston C may be so dierentiatedas to provide for any desired increase of pressure upon the upper head. We will suppose, for example, that an increased pressure of five pounds is thus exerted upon the upper head.

C3 is an exhaust pipe leading from the base of the cylinder C with which, for convenience, the exhaust pipe B4 may communicate.

C4 is the rod of the differential piston C. C5 is a spring engaged therewith.

Adjacent to the dierential piston C is a balanced piston D provided with piston heads (1, d', d2, ot similar dimensions." The balanced piston is located in a cylinder D. Steam at boiler pressure is lead into the balanced piston cylinder between its cylinder heads in any suitable manner as through an opening cl3v communicating with the cylinder C between the heads 0, c', of the differential piston and with the cylinder D between the heads of the balanced piston. The two cylinders C', D', also communicate, as through IOS) an orifice c2 above the head cof the difieren tial piston, the orifice c2 being controlled by the balanced piston D.

D2 is an exhaust channel communicating with the top and bottom of the cylinderD and with the exhaust pipe C3. A single jacket D3 may inclose the cylinders C', D.

Ddt is the rod of the balanced piston D.

It will be perceived by reference more particularly to Fig. 4 that when the balanced piston D is raised, steam is admitted at boiler pressure through the orifice c2 upon the top of the head c of the differential piston, and that when the balanced piston is at. its downward stroke, the steam is cut olf from the top of the diierential piston head c'. Obviously by letting the steam above the pistonheadc', the differential piston is caused to descend allowing the steam to pass through the pipe B3 upon the top of the piston B to open the .whistle valve. Then the differential piston is raised, steamis cutoff from passing through the pipe B3 and the whistle valve" is closed.

The movement of the differential piston is thus governed by the movement of the balanced piston. To control the balanced piston, Iconnect the rod of the balanced piston with an armature E, controlled by an electrical magnet E.

F denotes an electrical battery, and G and G the electrical conductors leading to and from the said battery., the conductor G leading directly to the magnet E. G2 is an additional electrical conductor leading to said magnet. The conductors G and G? are arranged to be thrown into and out of circuit the one with the other.

Into the circuit through the conductor G, G2, is interposed any suitable clock work, indicated in the diagram Fig. l at H, H indicating the frame of the clock work with which frame the conductors G', G? are connected.

Supported upon the frameH is a` contact plate J, made rotatable by the clock Work as required. J' is a spring arrangedto contact with said plate. The frame is provided with abinding postfh with which the` spring J is adjustably engaged, the spring being held` in position by means of a screw 72.', which may be provided with a spring h? to exert a proper `tension upon the spring J.

G3 is an additional conductor in electrical contact with the spring J and leading to a switch boardK governingthe circuit through the conductors G', G3.

K is the switch lever.

The switchl board may be provided4 with suitable contact points whereby theL current may be either directed througlrthe conductor G tothe frame of the clock wo,rk,or through the conductor Gr3 to the spring J.' in electrical contactwith the contact` plate J, or by which the clock Work and the` contact platewmay be directlycut out of circuit,.as indicated in the diagramFig. l. rPhe clock Work,`withiits contact plate J and contact spring J', when in circuit is arranged to automatically govern the current leading to the magnet E', and thereby automatically operate the armature E and, in consequence, the balanced piston D, thereby governing, as already explained, the whistle actuating valve. The contact plate J may be of any desired construction for sounding the signals required or a code of signals required. The contact plate might be made removable and interchangeable, so that a plate constructed to sound any desired code of signals may be engaged with the clock work.

l In Fig. 5, a contact plate is shown provided with a journal j upon which the plate is rotated, the plate being formed with, for example, four contact armsj, jjj These arms are offset one` from another laterally, so that the spring J may contact with any one or more of said contact arms in the rotation of the plate J, While the spring J is made adjustable laterally so that it may be moved to contact With any arm or arms upon the plate J as may be desired. The outer edge of each of the contact arms may be made to rotate in a different plane if desired or any multiple of them in the same plane if dcsired. We will suppose for illustration, that the outer edges of each. of the contact arms, shown in Fig. 5, rotates in a dierent plane. Then by setting the spring J to contact with any` given arm in the rotation of the plate J, the circuitwill be completed when the spring J contacts with the given contact arm, and the whistle mechanism will` be actuated automatically in accordance therewith.

WeWill suppose that the plate J, shown in Fig. 5, makes a complete revolution each moment of time, and that the spring is arranged to contact with the arm j. Obviously,.whenever the arm j strikesthc spring the electrical circuit will be completed, the armature actuated, and the whistle mechanismsouuded once every moment. Should it be desired to sound the whistle every thirty seconds, two of the contact arms would be arranged to havetheir edges rotatein the same plane,Y and consequently the circuit would be completed every thirty seconds through the contact spring J, and the whistle mechanism sounded accordingly. To sound a given code of signals, as many contact armsmay be provided as may be required and each of the contact arms may be variously formed to suit the code of signals. Should itbe required, for example, to sound four blastsof the Whistle every` moment, one of thearms, as the arm j?, maybe formedwith four contact points, as illustrated in Fig. 5, so that` whenever the` arm` 7'3 rotates under the spring` J', four blasts of the Whistle will be successively sounded every moment.

In Fig. 6, a contact plateof modified form is shown, each of the, contact arms being provided with a seriesof contact points, and as the spring J is set to contact with one or the other of the contact arms, the signal will IOO IZO

be sounded accordingly. It will thus be seen that a contact plate may readily be formed, or interchangeable plates may be located upon the clock work to automatically sound any code of signals desired, and the contact plates may be changed readily to suit any given circumstances.

I have alluded above to the desirability of a code of signals to ,indicate the direction of thecourse ofthe vessels in passing one another. We will suppose a code to be established whereby upon such an occasion a single short blast of a Whistle occurring a given number of times in a moment would indicate that a vessel was taking a northerly course; two short blasts occurringa given number of times in a moment, that a vessel was taking an easterly course; three short blasts occurring a given number of times in a moment, that the vessel was taking a southerly course; and four short blasts occurring a given number of times in a moment, that the vessel was piston to be operated by hand, which for this purpose may be provided with an operating lever L and a pull-cord L.

L2 is a support for the extremity of the lever L.

I do not confine myself to the use of the differential piston, as a spring might be used to unbalance the piston. 1

In a device constructed as hereinbefore described, when the circuit is broken, the balanced valve will drop to its place; but I would have it understood that I may use the balanced valve either with a closed or open circuit.

If the device were worked by a closed circuit, the teeth of the contact plate would form a circuit breaker.

The balanced valve might be dispensed with and the armature E be engaged with the piston rod C4 within the scope of my invention, but by using the balanced valve I am enabled to give to the piston C a longer stroke, and it would take more power to operate the piston C if the balance valve were not einployed. By using the balanced valve I make the steam actuate the piston C, where otherwise sufficient electrical power would be required to operate the diferential piston.

M denotes a spring engaging the armature Ev to retract the armature when the circuit is broken, and cause the balanced valve to fall to its normal position.

I prefer to locate in the exhaust pipe C3 a valve N which may be partially closed to contract the exhaust passage and thereby force a desired amount of steam pressure under the piston B to aid in raising it quickly to its normal position.

It Will be evident that the cylinder B ou the up stroke of its piston exhausts through the pipe B3 into the base of the cylinder C below the unbalanced valve therein, and thence through the pipe C3.
