.l Be itknownithatlglLEWIs C. -BAv'LEs, a citizen of the UnitedStates, and aI resident of Easton, in the`c0unty ,of Northamptonlv and State 'otlPennsylvanim have invented a certain SteeringA Apparatus, of which the following isa specificationv accompanied by drawings. i

.This invention relates to steering appara--v tus,"and although the features Yof the invention are capablejof general applicationthey possess special advantages when applied to the steering apparatus of boats or ships.

, The objects of the inventOn are to render steering apparatus of boats easily operrdolel and controllable; to enable the rudderto be operated by motive fluid ,by relatively inexpensive apparatus; andl to, enable, the helmsman toooutrol the rudder sothat it will. assume any desired predetermined position. The invention willbe more clearly under stood. byreference to the'following description' taken inaconjunotion with. the dra-Wing vvhich includes, p u .Y v

The construction: olf the motor L A and its Leont-rollingfthrottle valve isshoWn i'nfdetail in Figures 2, 3 land 4i.

Motive u id for actuating the gears' U andV .is supplied through one of a pairy of passages c and (i depending upon the direction Vin Whichv itiis desired to rotate/the' gears U and V.` The gear V is in this instance theidrivinggear andiv is provided with a shaftfu'p'on which the spiral gear vv P is vmounted'. It is un ion derstoodthat when the passagemc isfproavided with motive fluid fordrivingthe gears VU yand V'the passage v ai is disconnectedffromg ,the Supply of. motiv/@fluid arid Veeversai A throttlefvalve yfor 'controlling `the supv ply zof fmotivejiluid; to either the` passage 'c f "orthe .passage df c'oiriprss, the. mtaiyplug 11.0

valve f provided with a relatively long shank g extending upwardly from the motor to a convenient position to be turned by the operator and is provided at the en'd of the shank g with a manually opera-ble handle it. A sleeve j is also provided and is adapted to cooperate with the valve in Control-ling the supply of' motive fluid to the motor L.

^ The sleeve 7' is rotatable Within the outer cas passage c and likewise the passage g' is oo n-` stantl'y connected with the' passageja. Assuming that the rotary sleevey' remainssta-V tionary .and in its straight forward position as shown in Figure 2 a turning of the throttlevalve f to the left permits motive fluid to enter from the supply pipe 0 tlirougha Areduced vportion w on the periphery of the sleeve through a port m into the interior of the sleeve, through a reduced portion g/ on the peripheryof the throttle valve f and a port e to the passage p, and vthence to the passage 0 to actuate the gears U and V. This causes rotation ofthe drum B and a swinging of the rudder Ato the left which it will be noted is the direction in which the handle t is turned. Likewise a'turning Y of the handle 7L to the right causesmotive fluidto enter the reduced portion 2 andV through a port 3 to the passages' Q and d,

causing rotation of the gears U and V inV a direction opposite to that before described, and turns the drum Bin a direction causing the rudder to swing to the right, which it will be-A noted is the direction in which the handlelL has in this casebeen turned.

Means are provided to stop themotor L, land consequently the swinging of the rudder A at any predetermined or desired position Without manipulation of thevhandle 72, be-

y yond a first setting thereof. To this end the sleeveV j isrotated in accordance with the movement of the rudder A andby means of a sprocket 4 driving a length of chain attached at `its ends to llexible cords t'w'hich in turn are' attached to a length of chain 7 passing over' a sprocket 8 suitably mounted on the end'of the rotatable sleeve y' as by means of a key 9.

Thus whenthe rudder A swings. in either` Y direction as'the case may be by being actue atedby thedrumB the sprocket llthrough its above described connections rotates the sprocket` borne by theV sleeve j` so that the sleeve j follows the movement of the rudder A. The motor L therefore continues to run until the port ofthe sleeve j is cut ou' or moved out of communication with the re duced portions-y or 2' depending uponl the direction of swinging of the rudder A.

This operation is more clearly illustrated in' Figures 5, 6 and. In Figure 5 the handle 71, is in the position corresponding to the straight forward position of the rudder A. Assuming that it is desired to turn Vthe rudder A to the left as for instance approXimately 45 the handle 71, is turned that amount toward the left' which opens the throttle valve permitting the supply of ino-V tive fluid from the pipe 0 through thev port m in the sleeve j into the reduced portion y. of the throttle valve f and thencel into the passage gnwhereupon the motive fluid causes the motor L tooperate turning the druin B and swinging the rudder A to the left. The'r motor L continues/to operate until the turning of the drum B and thesvvinging of the rudder A, through the connections associf ated with the sprockets tV and 8, turn the sleeve to the position shownfinFigure 7 at which the port m is closed by the valve f. In this position the rudderA is substantially parallel to the handle 7i. It is assumed that in this case the proportions of the cross arm F to the diameter of' the drum B Will pro Vduce theV requisite turning of the sleeve to cause the handle h" and the rudder A to assume parallel "positions, Inl any case a given degree of turning of the handle will resultin aproportionate movement of the rudder A. Itis not necessary 'that Athe relative displacement of the two bel the same. To prevent the leakage of motive-fluid along the shank g'of the throttle'valve 165 a stuffing gland` 10is provided.Y about. the shank g in thefendof thesleeve j# Iclaim: "A, Y
