This invention relates to improvements in power steering gears lor boats, and the mvention consists in the matters hereinafter set forth and more particularly pointed out L in the appended claims.

Among the objects of my invention is to provide a steering gear for boats embracing a connection between the steering wheel, usu- C. AKERS, a citii wear between the i 1 l l l l 1 ally located at the pilot house, and the rudder, so a rranged and ellicient to promptly and with certainty as to be at all times reliable l transmit power to set in operation the rudder actuating mechanism, and of such char actcr as to unerringly indicate to the person i at the steering wheel the position of the rudder, and to maintain the relation of the rud POSSESSlllg may be reatily installed and which is economical to maintain.

My improved steering gear for boats embraces, in combination with the rudder and the wheel, the latter located at a point dis t'antfroign the rudder, a mechanism for operating therutlder to turn the same from side to srdefand a positively acting connection extending rearwardly from the steering wlieeltothe starting or controlling device of actuate said starting device.

' Iieretofore, it has been the practice to operate the. rudder actuating mechanism from.

.the steering wheel through the medium of "chains or "cables, there being two of such chains'or cables provided, one for transmitting mot-ion to swing the rudder inone other direction. A serious objection to this mode of transmitting power to control the rudder actuating mechanism is the lengthening of the chain or cable after some use, due

' to stretching, to which is added in the use of a direction and the other to swing the rudder in the l l l l l l l -Port-Huron-,--in 1 this reason the wheel actuated transmitting device is inaccurate to indicate the position of the rudder to the person at the wheel, and is ineffectual to secure a prompt response of the rudder to the steering movements of' the wheel. This defect has been emphasized in later years when a plyin the chain or cable mechanism to the owner oats, and much ingenuity has been displayed in devising means to overcome. the known existing defects. Later attempts have been made to overcome these defects by providing a device in the nature of a hydraulic appliance whereby motion is transmitted rearwardly from the wheel to control the rudder through the medium of a column of liquid. ism, while superior in point of accuracy and prom titude in transmitting motion rearward v from the wheel, has been found in practice tobe subject, in a somewhat less de-' gree, to similar defect-s found in the prior mechanism, owing to the fact of leakage of fluid from the iipes and past the moving parts of the mec anism, as actuating pistons.

of registration between the rudder and the steering wheel;

This Inechan- My im rovement consists in providing a rigid ant certain connection between the steering wheel and the rudder actuating mechanism, and its simplest and best form known to me at present is embraced in an inextensible rigid rod thatvis connected at its forward end with the steerin wheel and at its rear end with the controlling device of the rudder actuating mechanism, and is connected at its ends with said parts by means avoidin lost motion. The use of the rigid connection between the steering wheel and rudder actuating mechanism enables thelposition of the rudder, with respect to the position of the wheel, when once adjusted, to be maintained so that the man at the wheel is :able to steer the boat with absolute certainty because he knows the osition of the rudder and knows that the l\.l( der will respond accu ratelyl and promptly to the movement of the es A further object of the invention is to pro vide an improved auxiliary steering gear mechanism and means for operating said .on line 5-5 of Fig. 1.

, mechanism at a distance from the gear mechanism and rudder to connect said mechanism with the rudder.

Fig. 9 isa detail section, taken on line 9-9 of Fig. 6. Fig. 10 is an enlarged plan view of the main quadrant and the means for connecting the tiller chains therewith, and illustrating also a portion of the auxiliary gear quadrant.

Fig. 12 is a fragmentary, sectional view of the like parts at the other side of the quadrant.

As shown in said drawings,10 designates, as a whole, the hull of a typical boat and 11 and 12 the upper and lower decks thereof. The rudder 13 of said boat is operated by an actuating mechanism shown as consisting of a steering engine 14, of any preferred type, located preferably in the engine room abaft midships. Said engine op crates the rudder through the medium of tiller chains 15 connected to the usual quadrant 16 which is attached to the upper end of the rudder post 17. The valve mechanism rof the main steering engine is operated by 'the usual hand wheel 18 located in the pilot house 19. The steering wheel 18 is connected with the valve controlling rod or stem 20 of the main steering engine through the me dium of mechanism constituting part of my invention and made as follows:

21 designates a vertical rotary shaft ex tending downwardly from the steering wheel stand through the upper deck 11 and is operatively connected at its upper end. with the hand wheel 18 through intermcshing beveled gears. lower end by beveled gears 22 23 with the inner end of a horizontal rotary shaft 24 extending laterally towards one side or wing of the boat, and rotatively mounted in suitable hangers depending from the upper deck 11. Said horizontal shaft 24 is provided at its outer end with a gear pinion. 25 (Fig. 3) which meshes with a horizontal rack 26 car- Said shaft 21 is connected at its ease ried by or formed on the forward end of a rigid, lnextensible connecting rod 27 that ex-,

tends horizontally aft towards the main steering engine and is operatively connected at its rear end with the valve stem or rod 20 of said engine. between said connecting rod and valve rod or stem comprises a horizontal, rotative shaft 28 extending inwardly from the connecting rod to the engine andpr vided at'its outer end with a gear pinion 29 that meshes with a rack 30 carried by the rear end of said connecting rod. The inner end of said rod 28 is connected by suitable beveled gears with the upper end of said valve stem or rod 20. The said connecting rod 27 is made rigid throughout its length and is inextensible so that the, single rod transmits motion both fore and aft to operate the valve of the steering engine in both directions from its neutral position. The rod may conveniently be made of sections of pipe or tubes joined by unions 31, as shown in Fig. 3, the union in said figure indicating the connection'between the first section of the pipe and the rack bar 26. said connecting rod27 is supported'intermediate its length and guided by syitable ball bearing sheaves 32 located-in any. corl venient manner at the sides of the vessel. As herein shown,'the sheaves are mounted in brackets 33 depending from the upper deck, but may be supported in any other convenient manner.

In the operation of the mechanism described, rotation of the pilot house wheel 18 is communicated to the controlling rod or stem 20 of the main steering engine without lost motion and in both directions through the connecting rod 27, thereby contributing to the accuracy and promptitude of action of the mechanism with a simple, durable and economical mechanism. h'loreover, the connecting rod, supported as it is by the sheaves shown, may be operated with little power inasmuch as it does not sag but moves straight through or over its guide sheaves, nor is there a tendency for the connections to stretch under continued use. Moreover, said rigid incxtcnsible connection between the steering wheel and the controlling device of the rudder actuating mechanism enables the position of therudder to be accurately indicated at the wheel, after the'position of The the rudder has once been adjusted to that of ed from the rudder. Said auxiliary steering gear, when connected with the rudder in -a manner hereinafter described, is operated through the medium of an auxiliary steering gear engine or other rudder actuating mechanism 34 located at the stern of the boat on the deck 12, wherein shown, and the throttle valve ofsaid auxiliary steering gear engine is operatively connected with a manual controlling device, herein shown. as having the form of a hand wheel 35, located on thebridge-of the boat, and the wheel opcrates the auxiliary engine. valve by-connecting mechanism made like that described for operating the valve mechanism of the main steering engine.

The operative connections between file bridge controlling device 35 and the auxiliary steering gear engine embraces a vertical shaft 36 operatively connected at its upper end with said hand wheel 35 and extending through the deck 11 and connected at its lower end, near the transverse median line of the boat, by means of suitable beveled gears with a horizontal shaft 37 extending laterally towards the wing of the boat. Said shaft 37 is provided at its outer end with a gear )inion 38 which meshes with a rack 39 attached to or formed on the forward end of a connecting rod 40, like the rod 27 before referred to, that extends aft and is provided at its rear end with a rack bar 41 which meshes with a gear pinion 42 fixed to the outer end of a horizontal, rotary shaft 43 located near the auxiliary steering engine. Said shaft 43 extends inwardly towards the auxiliary steering gear engine 34 and is connected, through the medium of suitable beveled gears, with the controlling rod 44 of the valve mechanism of the auxiliary engine 34. The said connec" 'ng rod 40 is supported on and. guided by sheaves 32 carried by brackcts '33, as shown in Fig. 3, in the same manner as the connecting rod for the main steering gear engine is guided and supported. The mechanism for controlling the throttle valve of the auxiliary-steering engine from the hand wheel 35 operates in the same manner as does the .like mechanism for the main steering engine before described. That is to say, motion is transmitted from the hand wheel 35 to the auxiliary engine valve mechanism to operate the latter in both directions from a neutral position through the fore and aft movement of sa d connecting rod 4f). I I

Any suitable means may be employed for maintaining the rack bars 26, 30, 39 and 4] in mesh with theirrespecti 'e gear wheels, as for instance, by means of grooved guide wheels 45 hearing or. the upper faces of said bars and carried in suitable brackets 46 depending from the superjacent deck structure, as shown in Figs. 3, 6 and 9.

A further important advantage of the stock, not requiring special tools or mnchinery for the-manufacture thereof may be built at relatively small expense.

A further advantage of the apparatus is the ease and facility with which it may be adjusted to secure proper and accurate registration of the wheel to the position of the rudder.. p.

The auxiliary steering gear herein shown comprises a geared quadrant 46 fixed to and extending forwardly from the rudder post. and a gear pinion 4 7 in constant mesh therewith and mountedon a vertical shaft 48 that is given a backward and forward rotary movement from the, auxiliary steering en gine 34. Said shaft-48 is geared to the auxiliary engine 34 inahy suitable manner, as by means of a worm car 49 at its lower end which meshes wit a worm on the crank shaft 50 of said engine. The gear pinion 47 is loosely mounted on the shaft 48 so as to turn frcelythereon when the main steering gear is in service. It is desi ned to be locked to said shaft by means of a c lutch embracing,

as a part thereof, a sleeve 51 which is splined leased to drop into its clutching position,,

when the auxiliary gear is to be brought into operation, by the lollowing mechanism:

- 55 designates a lever which is pivoted at one end to a bracket 56 depending from the up er deck structure, and is formed to provlce between its ends a yoke 57 which fits loosely over the upper end of the clutch sleeve. The yoke. is pivotally connected with the clutch sleeve through the medium of a collar J58 fitting loosely in an annular grom'e in the upper end of said clutch sleeve. Said yoke is pivoted to the collar by means of short pins 5'2) extending through the side members thereof into the collar. This construction permits the clutch sleeve to rotate within the yoke while effecting an attachment thcrebetween which permits the sleeve to be raised by the lover. The lever extends beyond or forward of said clutch sleeve and is'normally held in its raised position through the medium of a latch 60 that is suspended from the upper deck structure in any suitable manner. Said latch consists essentially of a suspended releasing hook, one side memher 61 of which is provided with a suspending loop 62, and the other side member 63 of which is hinged to the lower end of the member 61 and is designed to swing or drop away therefrom to release the clutch lever 55. The hinged member of thelatch is held in its closed position by means of a retaining ring 64 which encircles the two members of the latch when the hinged member is in its closed position, in a manner to hold the same closed; and the hook is released by raising said retaining ring. The free end of the hook 62 is turned laterally outwardly to prevent the ring 64 from sliding too far downwardly on said latch. Said retaining ring'is raised, in the present instance, by a cord or cable 65 which extends aft from the bridge through I suitable guide sheaves 66 located beneath the deck ll'centrally of the boat (Figs. 2, 5

and 6) and is threaded through the latch beneath the retaining ring and attached at its rear end to a part located in rear of the latch. The latch 60 is located beneath the general level of the sheaves for said cord and tension on said cord, effected by a forward pull thereon, acts to raise the ring and release the hinged part of the hook, thereby releasing the lever and allowing the clutch sleeve to drop into itsoperative position.

Means are provided for disconnecting the tiller chains from the rudder when the auxiliary gear is brought into service, which is effected in the present instance by releasing the tiller chains 15 fromthe quadrant of the main steering gear. While the auxiliary steering gear would be operative to steer the boat without casting off the tiller chains from the quadrant yet such release of said chains is desirable in order to avoid injury to the parts and also to relieve the auxiliary gear of the .work of unnecessarily carrying and shifting the'chains when the latter are not in use.

The tiller chains 15 pass through the grooved rim of the quadrant and, as herein shown, are attached to the quadrant by means 01 turn buckles 67, each attached to one of the tiller chains in rear ofthe quadrant, at one side thereof, and extending transversely in rear of the quadrant in crossed relation (Figs. 2 and 10) and attached to the quadrant at the other side thereof. The turn buckles are attached to the. quadrant through the medium of releasing hooks 68 fastened to the opposite wings of the quadrant. As herein shown, said turn buckles are provided on their free ends with shackles 69 which engage the hinged or releasing members 70 of said hooks, whereby, when said hinged members are released, the loops fallaway from said hooks to release the tiller chaifis. In the form of quadrant herein shown, the turn buckles 67 cross each other in rear of the quadrant, so that one of said releasing hooks 68 is attached to the upper and the other to the lower sideof the quadrant, I as shown in Figs. 11 and 12. The swinging members of said releasing hooks are locked in eheir closed positions with the turn buckle shackles engaged therewith by locking devices made as follows:

72 72 designate latches made of inverted U-form and pivoted to the shanks'of the hooks in a manner to swing over and away from the hinged members of the hooks. Pivoted to the upper ends of said latches are links 73 (each herein shown as made of two parallel bars fastened on opposite sides of the latch) and said links are pivoted at their rear ends in like manner to vertically swinging levers 7 4 which are pivoted at their lower ends between the arms of U-shaped stand.- ards 75 fixed to and rising from the wings of the uadrant. The said levers extend 0blique y rearwardly from the standards 75 and are locked to the upper or closed ends of the standards by .means of pivoted L-shaped detents 76 hinged to the lever 74. One arm of eachv L-shaped detent is provided with a lug or tooth 78 that enters a socket in the upper end of the associated standard 76 and tothe other arm thereof is attached one end, of a looped cable or bridle 79. Said bridle 7 9 extends from one side to the other of the quadrant and is trained through guide pulleys 80,,one at each side of the quadrant, and extends at its ends through openings in the upper ends of the levers 7 4, and said ends are attached to the. swinging detents 76 as stated. The detents 76 are yieldingly held 76 attached at their upper ends to the arms of the detent and at their lower ends to the standards 75. It is desirable that the tiller chains be released or cast ofi from the'quadrant simultaneously with the connection of in their locking positions by means of springs the auxiliary gear with the rudder post in the manner stated. To this end the clutch releasing cable 65 is connected with the bridle. This is effected in the present instance by providing. the rear end of said cable with an eye 81 through which thebridle 79 passes. This construction ermits the bridle to swing freely with the rudder as the rudder is moved from one side to the other without inter fering with the connection between said bridle 79 and cable 65. From this construction it will be obvious that when the cable 65 is mounted in the stand of the bridge wheel 35, or by other suitable means, it acts not only to release the auxiliary gear clutch; lever latch and to bring said clutch into operation t'o'l.

i make the gear 47 fast to the auxiliary 0st 48, but acts also, through said bridle an its connection with the detents 76, to release the releasing hooks 68 and therebycast off the tiller chains from the mainquadrant.

' The 0 eration of the steering mechanism,

I as a whole, will be obvious from the foregoing lbut may be briefly stated'as iollows: The

drawn forwardly as by means of a Windlass 82 boat is normally steered through the action of the main steering mechanism, embracing the steering engine 14, connected with the main quadrant by the tiller chains 15, and the valve mechanism of said engine is operated from the wheel through the medium of any 7 1 suitable transmitting connections, as the con-- 'necting rod 27, and its connected rack. and pinion mechanism in the construction herein shown. In case the steering gear should become derangecha predetermined signal will be given to the man on the bridge, who will, at once, through the o eration ofthe cable 65 and the Windlass in t e upper wheel stand, release the tiller chains from the main nadrant and at the same time trip the c utch sleeve suspending the lever to bring the auxiliary steering mechanism into operation. Thereafter the steering will be controlled from the brid e wheel 35 and its associated connecting rod .40 in the manner before de= scribed.
