BOAT STEERING AND BEVERSING- GEAR.

Specification of Letters Patent.

Patented Sept. 9, 1919.

Application filed Mag '13, 1919. Serial No. 296,88 i.

To all whom it may concern:

Be it known that I, J one: Grnonen AuLsn- BROOK KITOHEN, of 7 Rose Bank, Scotforth, Lancaster, in the county of Lancaster, En land, a subject of the King of Great Brltaln and Ireland, have invented certain new and useful Improvements in Boat Steerln and Reversing Gears, of which the following 1s a specification.

This invention relates to boat steeringand reversing gear of the typesuch as descrlbed in prior Patent No. 1,186,210, in which two rudders are so arranged that they deflect or reverse the stream of water driven astern by the propeller in order to efiect steering and reversal of the boat without varyingthe speed or the direction of rotation of the propellers.

The object of the present invention 1s to provide a compact and simple form of gear having a minimum of joints or connections in which lost motion can occur and capable of being operated by hand or by power to suit requirements.

The invention comprises the combination with a sector or its equivalent upon each rudder stock, of chains or like flexible connections attached to such sector at the opposite ends of its circular face and in opposite directions to an operatlng pulley or its equivalent, the two flexible connections of each sector passing over separate gu de or jockey pulleys carried by a slide, with means for traversing the slides simultaneously in opposite directions, for the purpose described. j

Referring to the accompanying explanatory drawings Figure l is a plan view, Fig. 2 a sectlonal elevation, Fig. 3 a frontelevation, Flg. 4t an end view looking from left to right of Fws. 1 and 3, with certain parts omitted, and Flg. 5 an end view looking from right to left of Figs. 1 and 3 with certain parts omitted, of a rudder control gear constructed in one convenient form in accordance with my in vention. p

Fig. 6 is a diagram to illustrate the action of the gear. it

Fig. 7 is a diagrammatic perspectlve view of slides 0, p.

of rudders arranged in one convenient form for csontrol bythe gear illustrated in Figs.

to A

F igs. 8 and 9 illustrate in Ian and front elevation respectively a modi ed application of the invention. Figs. 10, 11 and 12 illustrate in diagram form a further modified application of the invention. p i

The same reference letters in the different views indicate the same or similar parts.

The rudders a, b are mounted on a concentric sleeveand spindle 0, cl forming rudder stocks, 1 and to the upper end of the spindle is fixed a sector e, while a similar sector f is mounted onthe sleeve ,0. Each sector has two grooves g, h in its circular face which serve to receive the guide chains, wire ropes or like flexible connections 71 (shown diagrammatically in Figs. 1 and 6) which are secured to each end of the circular faces of the sector so that the chains or ropes pass in opposite directions therearound. The other ends of each of the two chains or ropes, or if a single chain or rope be used for each sector, the center portion of the same, are or is secured to a drum or pulleyj which may be rotated by hand through the medium of a tiller bar or its equivalent, or by power in any convenient manner.

When two chains or ropes are used, they wind around the drum or pulley in opposite directions, that is to say while one chain or rope is being wound on the drum or pulley,

the other one is being paid out. Similarly if a single chain is attached to the drum, one end is drawn in and the other paid out.

There are two drums or pulleys j, 70 or double drum surfaces for each sector.

The two chains or ropes before referred to for each rudder stock sector 6, fpass around guide pulleys m, n, upon the opposite ends through equal distances in opposite directions by a right and left hand screwed spindle g which may be rotated by hand or by power in any convenient manner and which passes through nut-like parts 9, .9, one upon each slide. 1

The latter are traversed guide pulleys, m,n in opposite directions, re-

sulting in the sectors- 0, 7 being rotated through equal angles in opposite directlons. The drums j, k may be rotatedsimultaneously with or after the movement of the screwed spindle Q is completed, in order to effect steering of the boat while it is moving astern. r

7 By the arrangement of the guide pulleys m and 11.,it will be seen that the movement given to each sector is twice that given to its slide, so that a relatively narrow operating gear only is required to give the angular movements necessary to the rudders to control the boat in its direction of travel.

The arrangement of the slides a, p with guide pulleys m, a, provides a rapid means for moving the sectors 6, f in opposite directions for boat steering or speed variation purposes.

Instead of operating the slides 0, p by a right and left hand screwed spindle, we

may operate them by a pinion u (see Figs.

8 and 9) engaging two racks '2), w one upon each side.

In the arrangement shown in Figs. 10, 11 and 12, the pulleys m, n which serve to deflect the chains or the like '5 so as to move the sectors in opposite angular directions,

are operated by the links m from the lever y which is itself actuated by the hand lever the left hand ends of the sectors.

2. Figs. 11 and 12 show the arrangement of the two chains or the like leadin from it 4, 4 there are two superposed pulleys while the pulleys 5 are all single pulleys. A similar dispositionof parts is provided for the fchains or the like from the right hand ends of the two sectors. In this example, superposed pulleys m, a are mounted upon each "slide, instead of two single pulleys at opp0- site ends of the slides as in the previous examples. V

I may vary the details of my improved gear to suit any particular services or requirements.

Havingnow described my invention, what I claim as new and desire to secure by Letters Patent is 7 1. In boat steering and reversing gear,

two cooperatingrudders with rudder stocks, "a part upon each rudder stock,- rotatable means, two flexible connections between the 'a slide, as set forth.

tween the rotatable element and the two ends of each sector, and means deflecting simultaneously each pair of flexible connections, as set forth.

3. In boat steering and reversing gear, in combination, two cooperating rudders, concentric rudder stocks for the said rudders, a sector upon each rudder stock, a rotatable element, flexible connections between the rotatable element and the opposite ends of each sector, and means deflecting simultaneously each pair of flexible connections, as set forth.

4. In boat steering and reversing gear, in comblnation, two cooperating rudders with rudder stocks, a part upon each rudder stock, rotatable pulleys, two flexible connections between said pulleys and each part upon a rudder stock, and two pulleys deflecting simultaneously each pair of flexible connections, as set forth.

5. In boat steering and reversing gear, in comb nation, two cooperating rudders, concentric rudder stocks for the said rudders, a sector upon each rudder stock, rotatable pulleys, two flexible connections between said pulleys and the opposite ends of each sector, and two pulleys deflecting simultaneously each pair of flexible connections, as set forth.

6. In boat steering and reversing gear, in combination two cooperating rudders with rudder stocks, a part upon each rudder stock, rotatable means, two flexible connections between the rotatable means and each part upon a rudder stock, two slides, two pulleys upon each slide, means traversing the slides simultaneously in opposite directions, the two flexible connections of each part upon a rudder stock passing around and being deflected by the two pulleys upon I 7. In boat steering and reversing gear, in

combination, two cooperating rudders, concentric rudder stocks for the said rudders, a

sector upon each rudder stock, a rotatable part, flexible connections between the r0tatable part and the opposite ends of each sector, two slides, two pulleys upon each slide, means traversing the slides simultaneously in opposite directions, the two flexible connections from each sector passing around and being deflected by the two pulleys upon a slide, as set forth.

8. In boat steering and reversing gear, in combination, two cooperating rudders, concentric rudder stocks for the said rudders,

a sector upon each rudder stock, a rotatable part, flexible connections between said rotatable part and the opposite ends of each sector, two slides, nut-like parts upon each slide, a right and left hand screwed spindle passing through said nuts to traverse the slides simultaneously in opposite directions,

the two flexible connections from each sector passing around and being deflected by the two pulle s upon a slide, as set forth.

In testimony whereof I have signed my name to this specification.
