STEAM STEERING APPARATUS.

with the dial which indicates the position of the rudder, as hereinafter set forth.

In the accompanying drawings, Figure 1 is a sectional view showing the arrangement of the several parts of the apparatus. Fig. 2 represents a top view of the engine. Fig. 3represents an enlarged detail sectional view of the screw and not for changing the relative position of the reversing-valve. Fig. 4 represents an enlarged detail view of the connection between the eccentrics and the main valves of the engine-cylinders. Fig. 5 represents an enlarged vertical section of the standard which supports the trick-wheel. Fig. 6 represents a detail section taken at right angles to that of Fig. 5. Fig. 7 represents a top view of the trick-wheel standard, showing the dial which indicates the position of the rudder.

In the drawings, A represents the handoperated barrel or drum of the steerer, said barrel being mounted in suitable bearingsat the top of the standards B B, which are secured to the deck 0. The pair of engines D D are arranged to operate upon the shaft E, upon which is secured a worm F, (shown by dotted line in Fig. 1,) the said worm engaging with the teeth of the worm-gear 9, secured upon the drum-shaft H, mounted in the bearings a a. The drum I is secured to the shaft H, and the ropes or chains J J pass from the drum I tothe hand-operated barrel A, the said ropes or chains passing around the sheaves of the sliding pulley-blocks A, from which connection is made by chains or ropes B to the rudder, as usual in steam steering apparatus. The trick-wheel N is attached to the shaft 0, which is mounted in suitable bearings at the top of the hollow in conjunction with the nut h upon the shaft f will serve as a stop for the movement of the trick-wheel by hand when the proper limit of movement in either direction has been reached, the said vnut h being guided in its up-and-down movement by means of the fixed guide-rod 2','which passes loosely through a perforation in the arm 11"0f the nut.

Upon the shaft 0 is placed the worm j, which engages with the worm-gear k, secured upon the upright shaft-Z, at the upper end of which is secured the spur-gear m, engaging with the pinion n upon the shaft 0, to the upper end of which is secured the pointer 0, which in conjunction with the graduations q upon the covering-plate 1" will serve to indicate the angular position of the rudder relatively to the axis of the ship, andupon the shaft 0 above the pinion n are secured the arms 8 and t, which by engagement with the pins to and 'v serve to ring the bell w to attract the attention of the helmsman when the extreme point of steering movement in either direction is being reached, and thus preventing damage to the rudder-head.

The shaft f extends downward to the standard an, attached to the engine-bed, and upon the said shaft is secured the spiral gear a, engaging with the spiral gear of, which is provided with a screw-thread b, fitting the thread of the screw 0, which at its rearward end'is held in the bore (1 of the shaft H of the drum I and is held in the bearings e e of the standard at, and to the forward end of the screw 0' is secured the valve-rod f by means of the swivel-joint g, whereby the screw '0 will be allowed to revolve without imparting rotary movement to the valve-rod f. The screw 0 is secured to the shaft H for rotation therewith and for endwise movement by means of the pin h in the side of the screw and the slot 41 in the side of the shaft H. The spiral-gear nut a which serves to transmit the opening movement to the steam-valve of the engine D, is prevented from endwise movement by means of the bearing sides j j of the standard :25. Upon the movement of the trick-wheel in either direction the steamport will be opened and the valve be immediately brought back to its closed position by the resulting movement of the drum-shaft II. The preferable form of connection between the eccentric k and the main valve of the steam-cylinder D is shown in Fig. 4, in which the eccentric-rod Z is jointed to the sliding rack m, and connection is made with the rack n upon the valve-rod 0 by means of the intermediate gear I claim as my invention- 1. In a steam steering apparatus, the combination of the drum I, and shaft H, with the screw 0, having a sliding connection with the shaft II, the valve-rod f, connected with the screw, the spiral-gear nut a held against endwise movement upon the screw, and the spiral gear a for operating the spiral-gear nut to cause the movement of the valve-rod, substantially as described.

2. In a steam steering apparatus, the combination of the trick-wheel N, and bevelgears 61 and e, with the upright shaft f provided with the screw-thread g, the nut h provided with the perforated arm L, the fixed guide-rod & for the perforated arm of the nut, and the clamped screw-threaded stops it, h, arranged uponthe screw-thread of the shaft f at opposite sides of the nut, substantially as described.
