STEERING APPARATUS FOR BOATS.

SPECIFICATION forming part of Letters Patent No. 714:,035, dated November 18,1902.

Application filed August 12,1901- Serial No. 71,732. (No model.)

To all whom, it may concern:

Beit known that I, CHARLES ROGERS, a citizen of the United States, residing at Allegheny,in the county of Allegheny and State of Pennsylvania, have invented a new and useful Improvement in Steering Apparatus for Boats, of which improvement the following is a specification.

This invention relates particularly to innprovements in steam steering apparatuses for boats.

In apparatuses heretofore used for steering in the class of steamboats the steamactuated piston employed to operate the tiller required an unusually long stroke to give the proper tiller movement in both direction. Consequently the cylinder required proportionatelygreater length to accommodate such movements, thereby occupying considerable valuable space. Again, piston-rods of great length being at all times more or less exposed to variations of atmospheric temperatures become chilled and when in action cause the steam in the cylinder to condense by contact therewith. Further, in the above-mentioned class of apparatuses the usual arrangement of operating the tiller-rope was such that considerable slack was occasioned therein during movements thereof, which prevented perfect control of the tiller and caused considerable annoyance. Furthermore, the use of the foot-brake in connection with the pilotwheel is slow of action and at times is not in convenient position for the pilot to operate when necessity demands its use. Attempts have also been made to provide steering apparatuses with steam-actuated pistons of short stroke; but the mechanism for transmitting motion therefrom to the filler is complicated,easily disarranged, and therefore unsatisfactory.

The object of my invention is to provide a steering apparatus which will efiectually overcome the above andother defects exististing in the present form of apparatus.

The invention consists, first, in a steering mechanism comprehending a means for actuating the tiller, which includes a rod operated to control the action of the same, in combination with a braking mechanism having means constantly exerting a tendency to operate the same in one direction, and devices acting in opposition to said means and operated to overcome the power thereof, said opposing devices being controlled by said rod. Preferably the parts which tend constantly to operate the braking mechanism in one direction are such as automatically to release the same and the parts which act in opposition thereto are such as to set the brakes.

Secondly, the invention consists in certain peculiarities in the construction of parts and in certain novel combinations of elements, substantially as hereinafter described, and particularly pointed out in the subjoined claims.

In the accompanying drawings I have by different views shown means whereby my objects are accomplished, in which views Figure 1 is a pian View showing the outlines of a boat-body and the general arrangement of the steering apparatus thereon. Fig. 2 is an enlarged sectional side view through the pilot-house and engine-room at the fore part of the boat, showing part of the apparatus therein. Fig. 3 is a front View of the same. Fig. 4 is a sectional side view of the rear portion of the engine-room, showing the tiller. Fig. 5 is a front view of the brake mechanism enlarged and removed from the boat. Fig. 6 is a side view of the same. Fig. 7 is a side View of a portion of the same. Fig. 8 is a side view of the brake suspension-link. Fig. 9 is a front View of said link, partly in section. Fig. 10 is a vertical side view of the four-way-valve cock employed to control the steam at the cylinder, partly in section. Fig. 11 is a side view of the valve-casing in section. Fig. 12 is a plan View of the tillersaddle. Fig. 13 is a longitudinal side view of the same.

Further reference to the drawings for a description of the detail parts of said Views and their operative arrangement, the numeral 1 represents the first deck of the boat, and 2 the second deck, which second deck has upon its forward part the pilot-house 3. In said pilot-house is secured the bearings 4, in which is mounted a shaft 5, carrying the pilot-wheel 6 and drum 7.

The numeral 8 represents the tiller, which is arranged at the rear of the boat on the first deck. This tiller at its under side is provided with a small wheel 9, which is adapted to travel upon the elevated radial track 10, and a rod 11, to which is attached the ends of the ropes 12. These ropes pass in opposite directions over the pulleys 13 at the forward end of the tiller, thence over the pulleys 14, 15, 16, and 17, and around the drum of the pilot-wheel.

The pilot-wheel brake consists of a pair of brake-beams 18 and 19, pivotally suspended at their upper ends from the under side of the pilot-house floor 20 or other suitable support, each of which is provided at its lower end with a shoe 21 to engage the sides of the pilot-wheel rim. To an upright beam 22 is pivoted a crank-lever 23, which is connected at its crank end to the said brake-beams by the rods 24 and 25 and is provided at its op posite end with an adjustable weight 26. Another lever 27 is pivoted to an upright beam 28 and is connected at one end to the aforesaid lever 23 by a rod 29 and at its opposite end to a vertical foot-plunger 30, extending down through the pilot-house floor. The weight 26 tends to release the brakeshoes 21 from the pilot-wheel, which tendency is normally resisted by the lever mechanism hereinafter described, which acts in opposition to said weight.

Arranged Within the engine-room is a bedplate 31, upon which is rigidly secured a cylinder 32. A piston-rod 33 extends through said cylinder and has secured thereto within the cylinder a single piston. To the ends of said piston-rod are secured the carriages 34, which are provided at each side with brasses 35 to slide upon the bed-plate. A small shaft extends across each of these carriages, and upon each of said shafts are secured the grooved pulleys 36. At each end of the bedplate is secured a frame 37, having a shaft 38 mounted therein, upon which are secured grooved pulleys 39.

Upon the tiller is secured a saddle 40, having thereabout the rope-engaging grooves 41. Two cables 42 and 42 are each secured at one end to an adjustable rod 43, which is arranged on the top of said tiller. These cables each pass around the saddle-grooves in opposite directions and are prevented from chafing each other where they cross by the spaced grooves 41, within which they are respectively located. Thence the ropes pass over the overhead pulleys 44, which are secured in position slightly rearward of the saddle, along and over the pulleys 45, thence down and under one of the pulleys 29 on the bedplate ends, up and over one of the outer pulleys 36 of the piston-rod, thence up and over the same to the central piston-pulley, down over the remaining fixed pulley 39 of the bedplate, thence up and over the remaining piston-pulley, and extend along to the ends of the bed-plate, where they are secured at 46.

A steam-pipe 47 extends downward from a supply-pipe at about the center of the bed plate and has connected to the lower end thereof the four-way valve 48, from which lead the branch pipes 49 to each. end of the cylinder and the exhaust-pipe 50. At the point where the said pipes 49 branch from the valve a cock 85 is attached.

The four-way valve, which I prefer to use, but do not claim per se herein, consists of a casing 48, having a tapered interior, into which extends the two transverse steam-supply ports 49, from which extend the branch pipes to each end of the cylinder, the main supply-pipe port 27, and the port 50for connections with the exhaust-pipe. Upon the interior of this valve-casing, near the upper and lower ends thereof, are formed the annular grooves 51 and 52, which are connected by a by-pass or port 53, and at the lower end of said casing, communicating with the said lower annular groove, is formed an exhaustport 54. Rotatably fitted within said valvecasing is the tapered plug-valve 55, provided with two side ports 55, which ports are capable of registering or non-registering, as desired, with any two ports in-the casing when rotated. Across the lower end of this valvecasing is secured a bar 56, which is provided with a setscrew 57. This set-screw is adapted to centrally engage the lower end of the valve and hold the same in operative position and when desired adjusted to take up the wear of the valve. The upper end of the valve is connected to a vertical rod 58 by a coupling 59, which rod is provided at its upper end with a crank 60, to which is connected a rod 61, which rod extends forward to a point beneath the pilot-house.

Extending down through the pilot-house floor and upper deck are the axially-movable vertical rods 63 and 64, each of which is at their upper ends provided with a handle 65, which rods are mounted to a frame 66 in the pilot-house. The rod 64 terminates beneath the pilot-house and is provided with a crank 67, which is connected to a similar crank 68 upon the rod 63 bya rod 69. Another crank 70 is secured to the lower end of the aforesaid rod 63 and is connected to the aforesaid rod 61. Connected with one of said rods, so as to be actuated by movement of either of the same simultaneously with the action of the tilleractuating mechanism, is the means, hereinabove referred to, which acts in opposition to the Weight 26 and causes the brakeshoes 21 to be applied to the pilot-wheel and held there against the tendency of said weight. to release them when the tiller is in its normal or inactive position, said means preferably being as follows: To the said rod 63 is secured another crank 71, upon the end of which is loosely secureda strap 72. Pivoted to this strap is the small rod 73, which is provided at its lower end with a vertical opening, into which is loosely fitted a rod or pin 74, said pin having an eye formed within its lower end, to which is pivoted another strap 75. A lever 76 is loosely suspended upon the lower end of the foot-plunger 30 and retained in such po sition bya nut 30 onsaid plunger. This lemg in the strap 75, and when in its normal positionit holds the foot-plunger downward and prevents the weight from releasing the brake-shoes, being itself held down by the shortening of the connection formed by the members 73 and 74, which members when the parts are in the position stated are telescoped one within the other. The end of lever 76 remote from the strap 75 is pivotally connected to an upright beam 78 by means of a link which is composed of the two members 79 and 80, which are hingedly connected one to the other, each of said members having a shoulder thereon to engage one another and form a knuckle-joint. One of these members is connected to the lever by a spring 81 and rod 82, and the other member is connected to a small rope 83, which extends up through the fioor of the pilot-house to a convenient point in reach of the pilot.

In all views the tiller is shown as in its normal or inactive position and the brake set to lock the wheel in such position.

The operation of the steering apparatus and brake, with my improvements thereon, would be as follows: The pilot standing in front of the wheel finds it necessary to operate the tiller in either direction duringthe course of the boat or in turning grasps one of the handles and moves the same in the desired direction and to whatever degree required. Moving said handle causes the rod 63 to turn correspondingly, thus swinging the crank 71 and strap 72 in a horizontal are and carrying with the same the upper end of the connection, composed of the telescopic members 73 and 74, causing said connection to assume an inclined position or a position of greater inclination than that previously occupied by it and withdrawing the member 73 from said member 74, thus relieving the pressure on the strap 75 and lever '76 and enabling the weight 26 to act to force said end of the lever upwardly, as shown in dotted lines in Fig. 5, and simultaneously to force the rods 24 and 25 in opposite directions, so as to carry the brakes away from the pilot-wheel. At the same instant that the said handle 65 is turned a corresponding movement is transmitted to the valve 55 through the medium of the connections 58, 60, 61, and 70, admitting steam to the desired end of the cylinder, which steam acts upon the piston, forcing the same outwardly in a direction opposite to the movement of the tiller, causing the distance between the wheels carried by the piston-carriage and those secured to that end of the bed-plate to be shortened and the distance between those at the opposite end of the piston-carriage and bed plate to be proportionately increased. The movement of the said piston and wheels causes the cable 42, which is attached to or extends from that side of the tiller engaging the wheels 36 and 39, to be let out, and the other cable 42, which leads from the opposite side of the tiller around the other wheels 36 and 39, to be proportionately taken up, thereby operating the tiller in the desired direction. Reversing the movement of the said handle 65 causes the steam to cutoff and exhaust from that end of the cylinder and be admitted to the opposite end, and when the handle 65 has been returned to its normal position the steam will again be shut off and exhausted and the brakes applied.

In the absence of steam, as in emergency the pilot-wheel is rotated by hand to operate the tiller through the medium of the drum 7. and cables 12, in which case an instant release of the brakes is had by pulling upon the rope 83. The pulling of this rope causes the suspension- link members 79 and 80 to move outwardly at their hinged connections in the direction of the pull, thereby shortening the distance between its end connections, permitting the lever 76 to ascend sufficient distance to cause the weight 26 to act in releasing the brakes. When said rope 83 is released, the spring 81 overcomes the action of the weight, restoring the suspension-link to its normal position and setting the brake.

When the pilot-wheel and brake are operated in cases of emergency, as above set forth, the piston and mechanism connecting the same with the tiller would perform the same movements as in the case of steam-supply,and in such case the imprisoned air in the cylinder would be compressed, retarding the movement of the piston, and to avoid such compression the cocks 85 on the steam-supply pipes are opened, permitting the air to freely exhaust.

One important feature of this invention is the means employed to prevent slack in the cables 12 during the movements of the tiller, embracing an advantageous arrangement of saddle 40, cables 42, and pulleys, the system of pulleys including two,44, which are slightly rearward or out of line with the saddle 40 (in accordance to the radius described or limit in the tiller movement) and the parts being so combined that when said tiller is in its normal or inactive position the cables 42 will both engage the entire length of the saddle, and when the said tiller has moved, as indicated by dotted lines at Fig. 1, in either direction one of said cables will bear upon and extend out at an angle from the corner of the saddle and the other bear upon the entire length thereof and extend at a different angle.

Another important feature of my invention is theprovision of the annular groovesin the valve-casing and the by-pass and port connected therewith. These grooves being stationed at a point immediately above and below the valve-ports arrest leakage of steam and conduct the same therefrom. By arrestl ing the steam-leakage at this point and con- &

ducting the same therefrom the valve may be adjusted to permit a free and easy movement thereof.

Anotherimportant feature of my invention is that by the use of a short-stroke piston I am enabled to greatly multiply the movement of the tiller through the medium of the traveling and stationary pulleys and ropes, which in this case is six to one, and by the use of more or less pulleys a proportionately greater or lesser movement may be obtained.

Further features of importance reside in the means of quickly releasing and applying the wheel-brake during steam service and non-service, the means of preventing air compression in the cylinder during emergency or absence of steam service, and means of arresting steam-leakage and conducting the same from the valve, aspreviously described.

As I have shown and described my improvements in connection with parts which are old in the art of steamboating, only such parts as are contained in my invention will be claimed.

, Variation of detail parts or substitution of equivalents therefor combined to effect the same results or change of position would be within the scope of my invention.
