Fig. 16 is a plan view of end of the crank, while lateral movement of the piston-rod is prevented by guides 69. 7 is a pump or suitable machine for the compression of air. This is connected by a dischargepipe 8 to an air-reservoir 9. 10 is the controller-valve, or, to be exact, is the chamber inclosing the valve, provided with an operating-lever 11 11. A pipe 12 leads from the reservoir 9 to the valve-chamber 10. Also connected to the valve-chamber are two pipes 14, which lead to the motor-cylinder 5 and are connected to opposite ends thereof. An exhaust-pipe 15 is connected to the valve-chamber 10.

Referring now to Figs. 3 and 4, 16 is the piston of the motor. 17 17 are ports which connect the pipes 14 to the opposite ends of the cylinder. These ports act alternately as inlet and exhaust ports. The ends of the cylinder may be provided with drip-cocks 18 for draining any accumulated water from the interior of the cylinder. The bearing under the cylinder may be of any suitable or preferred construction. Fixed on the ruddershaft above the motor-crank 4 is a sheave 19, adjacent to which are two pairs of pulleys 20, around which passes an indicator cable or wire 21, which leads to the indicator 56. (Shown in Figs. 5 and 6%.) This indicator will be described hereinafter.

The controller-valve will now be described, reference being had to Figs. 5, 6, 6 1-, and 7. 10 is the main valve-chamber, to the bottom of which is secured a casting 25, provided with four nipples 26 27 28 29, to which the air-pipes 12 14 14 15 are respectively connected. 24 represents bolts by which the above-named parts may be secured together. The four nipples register with four ports 12' 14 14 15 through the valve-seat, said ports being shown in plan in Figs. 8 to 14, inclusive. Port 12 may be termed the live port, as it is connected to the compressed-airsupply pipe 12, Fig. 1. The two ports 14 may be termed the motor-ports, they be-.

ing connected to the pipes 14, which lead to the motor cylinder. 15 is the exhaustport, as it communicates with the atmosphere at all times and may be connected to both or either of the motor-ports by turning the controller-valve 30 to certain positions, as hereinafter described. 30 is the controller-valve, which is provided with a three-way port 31 31 31. Crossing under one branch of said port is a port 32, which connects two recesses 33 in the valve. At diametrically opposite points of the face of the valve are openings 34 34 of two ports which intersect each other at 35, Fig. 5, and emerge at 36 and 36, Fig. 6.

Figs. 8 to 14 are diagrams of the valve-seat 23, showing or indicating the operations of the valve 30 in seven different positions thereof. The radial lines in Fig. 6 indicate these positions of the valve as determined by the center line of the valve handle or lever 11.

Substantially duplicate cut-off or auxiliary valves are provided for the motor air-pipes 14. Preferably said valves are seated in the valve-seat 23, as shown in Figs. 15 and 16. By means of these valves the communication between the motor-ports 14 is closed at all times during which it is desired to hold the rudder stationary, or substantially so, asmore fullyreferred to hereinafter. The preferred means for operating the controller-valve and said auxiliary valves is constructed as follows: The controller-wilve is provided with a stem 38, Fig. 5, on the upper end of which is suitably secured a hand-lever 11 11. An expansion-spring 39 may be housed within the stem 38 for providing a suitable pressure between the valve and its seat when the live port is closed. On the bottom of the valve is formed a concentric boss or journal 40, which fits a central opening 41 in the seat 23. The valve may be provided with a spring-pressed friction-shoe 42, which bears against the annular flange 43 at the top of the valve-chamber for the purpose of increasing the force necessary to move the valve or preventing the valve from moving too easily.

In order that the auxiliary valves 37 may be simultaneously operated by the movement of lever 11 11, 1 preferably employ the device shown in Figs. 15 and 16 with rockerarms 44 or equivalent means fixed upon the valve-stems 45, a lever 46 fulcrumed on a bracket 47, and rods 48 connecting the rockerarms to said lever. The outer end of said lever is bent upwardly and provided with a hori- Zontal extension 49, which is adapted to be engaged by the aforesaid hand-lever 11 11, which is jointed at 50 to permit its being broken at that point and turned either up or down. Its downward movement actuateslever 46, draws up rods 48, and thereby rocks the valves 37. These valves are normally open; but when the hand-lever section 11 is fully depressed they are closed, thereby cutting off the air in pipes 14 from the connecting-port 32 for the purpose of preventing the escape of air from either-end of the motor-cylinder at times when the rudder is to beheld. Means, such as one or more springs 51, are provided to automatically open the valves 37 when lever-section 11 is lifted out of engagement with lever 46;

The connections efi'ected by different positions of the controller -valve 30 are as follows, reference being had to Figs. 8 to 14, inclusive, and to Fig. 6: When the valve is in its middle position, (shown in full lines in Fig. 6,) the motor-ports 14 are open, the live port 12 is open and connected to the ports 14, and the exhaust-port 15 is closed, as indicated in Fig. 11. In Figs. 8 to 14 the shaded areas of the ports indicate closure thereof and the dotted lines indicate connections. In this position, a, of the valve the rudder is free to be operated by the steeringwheel in the pilothouse or by other suitable means, as the air which is expelled by motion of the rudder from either end of the motor-cylinder will in this position of the valve pass into the other end of the cylinder through pipes 14: and connecting-port 83 32 33, Fig. 6. Supposing next that the valve has been turned to the left to position I), the connections formed thereby are shown in Fig. 10. One of the motorports remains connected to the live port; but the other motor-port has been closed and the exhaust-port remains closed. This is preparatory to forming an atmospheric connection with the motor-port that'is now closed. The next position, 9, of the valve forms the connections shown in Fig. 9. The port that was closed at I) is now partially connected to the exhaust-port or atmosphere, thus decreasing the air-pressure upon one side of the motorpiston, and the excess of pressure upon the other side thereof causes the pistonto actuate the rudder-say in the port direction. The next position shown (marked 6 in Fig. 6) forms the connections shown in Fig. 8. The live port is now closed and both of the motor ports are connected to atmosphere through the three-way port 31 in the valve.

This permits the air-pressure in the motorcylinder to fall to normal, and in this position also the rudder may be controlled by hand or by electric or hydraulic steering-gear independently. Moreover, this pneumatic gear may be operated simultaneously and in connection with any other form of steering-gear. The reservoir is cut ofi' from the atmosphere, preventingescape of air therefrom. The three right-hand positionsof the valve marked '0, f, and (Z in Fig. 6 correspond to the left-hand positions 6, g, and c, and the efiect upon the rudder is the same except that its movement is reversed, as from port to starboard, or vice versa.

A dial-plate 52 is mounted upon the valvechamber 10, (see Fig. 6% for a plan view thereof,) and the valve-lever is provided with an index 53, which in its operation will register with indicating-marks on the dial-plate corresponding to the principal positions of the valve-lever. Beyond its joint the leversection 11' may be provided with another joint 63,-(see dotted lines in Fig. 5,) whereby the outer section thereof may be laid back upon the indicator-box when not in use.

To hold the rudder in any desired position, it is only necessary to push down the section 11 of the main lever. This Will close the auxiliary valves 37, as already described, and the ends of the motor-cylinder will thus be cut ofi from the atmosphere, the reservoir, and from each other. The air in the cylinder and in pipes 14 being at a high pressure is practically incompressible or is compressihle to such a slight extent that the piston will be held practically immovable so long as the valves 37-are closed.

The air-compressor may be provided with an automatic device for starting and stopping the same, starting it when the air-pressure falls below the required degree and stopping it when the pressure reaches or exceeds that point.

Figs. 5 and 15, in connection with Figs. 3 and 4, illustrate a novel apparatus for keeping the movements of the rudder before the eyes of the pilot or steersman. My preferred arrangement is to mount a supporting-casing 55 upon the valve-chamber 10, as shown in Fig. 5. This supports a casing 56, which contains a gear and pinion 57 and 58, to the latter being secured a pointer 59, which plays above a segmental index 60. The pinion 58 is actuated through bevel-gears 61 from a sheave 62,

around which are wound one or more turns of a small wire or cable 21. This wire or cable is conducted, by means of suitable antifrictionguides, to the aforesaid sheave 19 upon the rudder-shaft 2. I prefer to pass the cable over pulleys 20 and under pulleys 20, as shown in Fig. 3, before it passes around sheave 19. By this means every movement of the rudder will be transmitted to the pointer 59, which is distinctly visible to the steers= man. The diameters of the sheave and gear wheels might be so proportioned that the pointer 59 would follow the movements of the valve-pointer 53, above mentioned.

Having thus described my invention,what I claim as new, and'desire to secure by Letters Patent, is
