STEAM HYDRAULIC s'rasnme APPARATUS.

BPEOIFIOATION forming part of ReilIued Letters Patent No. 9,200, dated May 18, 1880. Original No. 208,231, dated September 24, 1878. Application for reissue filed February 4, 1880.

To all whom it mag concern 1 Be it known that I, JOHN GATES, ot' Port land, in the countyof Multnomah, in the State of Oregon,-have invented new-and useful Improvements in Steam or Hydraulic Steering Apparatus; and I do, hereby declare the following to been full, clear, and exact description of the same, reference being had to the accompanying drawings, and to the letters of reference marked thereon.

This invention consists, mainly, first, in the combination, with a rope, chain, or other. line of connection uniting the steering-wheel to the rudder, of a cylinder-piston located on the line and forming a part of the same, the construction being such that either the steeringwheel or the piston may be actuated independently to move the rudder without the change of any part; and, second,.in the combination, with a rope, chain, or other lineot' connection uniting the steering-wheel to the rudder, of a cylinder having ,a 'piston which is so far independent of the line of connection as to permitthe latter to render through it-without actuating it when the steering-wheel is used to move the rudder.

-It consists, further, in certain details of construction, which, in copnection with the foregoing, will be fully described hereinafter.

In the drawings, Figure 1 represents a side elevation of one method of employing my improved apparatus; Fig. 2, a longitudinal sectional elevation of one of the hydraulic cylinders; Fig. 3, an enlarged 'view of one end of the same; Fig. 4, an enlarged view of the metal piece by means of which the ends of the tiller-ropes are secured tothe steering-wheel; Fig. 5, a plan view of the hydraulic cylinders and the system of pipes; Figs. 6, 7, 8, and 9, various views of the valve mechanism; Fig. 10, a side elevation of another method of cmploying my improved apparaius; Fig. 11, an enlarged view of the clutch mechanism of the steering-wheel Fig. 12, a side elevation of a and use my invention, I will now. proceed to describe fully its construction and manner of operation.

A, Fig. 1, represents the deck of a. steamer,

ropes, which equal in length the extreme distance moved by the tiller, and are provided at one end with a stalling-box, b,-Fig. 2, and

at the other with an opening, b Fig. 3, as shown.

'b, Fig. 3, represents a piston adapted: to move in the cylinder in the usual manner, which has a central opening, as shown. Ir, Fig. 2,

represents a hollow pistonrod attached there to, the free end of which projects outward from the cylinder through the stufling-box, as shown.

0, Fig. 1, represents an extension of the rod, either rope or chain, the rear end of which is attached to the rudder in any proper manner. D, Figs. 1 and 5, represents a valve chest or chamber located at any proper point, but essentially upon a lower planethan the cylinder, in order that the contents of the latter, when. not under pressure, may HOW to the former by the force of gravity,-and preferably, for convenience, in line below the pilot-house. d. (1, Figs. 1 and 6, represent pipes, connected at one end to the cylinder in such manner as to open thereinto between the closed end' and the piston, and at the other to the valve-chest, in such manner as to connect with the inletports d d, Fig. 7, as shown.

follows that when the valve is moved to admit water upon one side a square opening will be exposed fora passage of the same, whileon the opposite side around opening of less area will be exposed fro/permit. the exhaust.

d, Fig. 1, represents ashaft passin through a stuffing-box in the valve-chamber, which is provided" below with=apinion, as shown in Figs. 6 and 9, or other suitable device for actuating the slide-valve, and above with a for convenient manipulation.

and 5, represents same purpose for which it is employed in other places.

F, Figs. 1 and 5, represents a pipe connected at one end to the valve-chamber D and at the' other to the reservoirG near its upper end, as

' The feed-pump being shown. g f represents a throttle-valve,

, and f, Fig. 1, an actuating rod or shaft extending into the pilot-house,- by means of which the supply of water into the valve chamber can be cut ofi' whenever it is desired to stop the action ofthe H, Figs. 1 and 5, represents a pipe leading into the top of the reservoir G, which connects at its other end with the feed'pipeg near the feedpump, which supplies the boiler with water.-

The operation is substantially as follows: in operation, a supply of water will be delivered tothe reservoir and to the system of pipes leading therefrom.

When it is desired to use the apparatus the the lever .of shaft d in the By thismeans water is adpilot simply turns proper direction.

mitted from the valve-chest D, through the pipe 6!, to pressure of the entering water the piston of this cylinder is driven forward, and conseis caused to move in the When it is desired to steer-in the oppositedirection the lever-handle is so turnedas to. admit water from the valve-chest into the other pipe d, in'consequence of which its piston will be drawn forward to actuate the tiller-rope,

while the first piston will be consequently drawn backward, the water contained in its cylinder flowing out through the exhaust.

When it is desired to hold the rudder in any desired position the lever-handle is turned into acentral position,-by which means-the ports are closed, the valve having a halt inch lap, and the columns of water contained in the cylinderslocked therein. The pistons may be, of course, in difl'erent positions in the cylin- 7, in consequence servesas an exhaust,

the movement of the rudder the rope in the usual well-known made to the lower part throttle-valve is ders relatively to each other, and the watercolumns consequently be of diflerent lengths; but, nevertheless, the rudder will be rigidly held, because no movement of the non-elastic columns can take place until the ports are again opened.

The port, which for the time being serves as an inlet-port, is opened upon the side which is straight, while the corresponding port, which is opened upon the side which is curved, fromwhich it follows that a larger area is furnished for the inflowing stream than for the outflowing. By means of this construction of parts the rudder is always desired position under ordinary circumstances.

When moving in either direction itis, of course, rigidly held, because the piston attached thereto is positively acted upon by a moving column of water, which drives it in one direction against the resistance of 7 another column flowing through a contracted orifice.

When the position of the valve is suddenly changed the rudder is still rigidly held, because the pressure on each side is still retained, but the excess thereof is transferred from one side to the other. If, however, it any time that the rudder should come in contact with an immovable obstacle and pressure be exerted thereonexceeding that of the pressure in the boiler, the rudder would then move the pistons and force the water orsteam back-through the valve-chest (the valved, if covering the openings, being lifted from its seat) into the res-' ervoir, or even means of relief the breakage of any part is prevented under such circumstances.

The cylinders, it will be observed, are single-actiug, a positive action being exerted only when the piston-is moving in a forward directhe return movement of each being effected by the forward movement of its fellow, the rods being united by the tiller-ropes, as

- described.

In order that the apparatus may continue to work, even if the feed-pump is stopped for a short .period,'a hole of proper size may be placed in the check-valve at the boiler, by which means steam or water will be admitted to the reservoirto create the proper pressure. If desired, a larger connection might be of the boiler.

If desired, the piston may directly by the steam but water is preferred, gecause it is less elastic and does not conense position of the rudder will be indicated by the-steering-wheel, which then serves as an index.

When it is desired to steer by hand the employed to cut oft the flow into the boiler itself. By this,

How therefrom by permit the pistons to rear end of the cylinders,in' which position they will remain until mitted.

The tiller-ropes, when the wheel is operated by hand, render freely through the hollow piston-rods and operate the well kno'wu manner. y

The change from hand'to power-steering, it will be understood, may be readily made at any time, when desired, of any part, the piston in one case, being em-. ployed'to actuate the rudder, and the wheel in the other case.

The hollow double rudder in the usual purpose: first,--by means of this constructiou an instantaneous change may be made from steering with the with the power of water of the boiler to steering wheel by hand in the usual manner; and, second, by means of this construction the water is permitted to run out of the cylinders, which draws the pistons back to the after end of the same and forces out therefrom the, rods, in consequence of'which the cylinders are not liable to injury from rust or frost, and the rods are permitted to. dry.

By means of the special construction, the use of cocks and valves in the pipes is dispensed with, the throttle-valve and slide being alone employ to obtain the desired results.

A modification of the foregoing is shown in El 10 and 11. In this two single-acting cyliu ers, I, Fig. 10, system of pipes and valves; but the cylinders am located away from the 'line of the tillerropes, as shown. These pistons are connected to the steering-wheel by means of .a chain, 1", Figs. 10 and 11, and pulley i, the latter being connected to the steering-wheel by means of any proper clutch device having a proper shifting-lever,- as shown.

The tiller-ropes are connected to the whee and tiller in the usual manner.

The operation is substantially as follows: The wheel may be used in the ordinary way by simply throwing the pulley P out of gear, as shown in Fig. 11. When it is-desired to use the hydraulic apparatus the pulley is thrown under the pressure .move backward to the the wa'teris again adwithout the change 13 and 14. -J,

Another modification is shown in Fig. 12.

This is substantially likethemodification just described, with the exception that one doubleactihg cylinder is employed in the place of two single 'acting cylinders. The arrangement of the supply pipes must be modified, of course,. for this cylinder pistons and piston-rods serve a in themanner well underst od.

A modified form of valve is shown in Figs.

Fig; 13, represents a shaft, which is connected at the-proper point to the valve j by means of shoulders j. represents a threaded bearing, through which passes the threaded ends of the shaft, as shown. The operation is substantially as follows: When the shaft is revolved it is necessarily caused to move in a longitudinal direction in the threaded bearing, and to carry with it the valve attached thereto.

By means of this construction the valve may be adjusted with great nicety and be securely, held in any position in which it may be placed.
