STEERING MECHANISM.

Specification of Letters Patent.

Patented Mar. 11, 1913.

Application led January 22, 1910, Serial No. 539,534. Renewed January 4, 1913. Serial No. 740,237.

To all whom t may concern:

Be it known that I, JOHN A. SEELY, a citizen of the United States, residing at Ogdensburg, in the county of St. Lawrence and State of New York, have invented new and useful Improvements in Steering Mechanism, of which the following is a specification.

My invention relates to certain new and useful improvements in steering mechanism, and relates more particularly to a steering mechanism for motor boats.

The object of the invention is to provide a steering mechanism of this character in which the steering wheel will embody a spark control and a gas control or throttle.

A further object of the invention is to generally improve and simplify, and at the same time to lessen the cost of manufacture and increase the efficiency of mechanisms of this type, and to provide an improved type of holding means for the steering mechanism itself.

Further and other objects will be later set forth and of themselves evidenced.v

In the drawings: Figure 1 is a sidelelevation, showing some of the parts broken away and in section, of the improved device, Fig. 2 is a fragmentary section taken longitudinally through the lower end of the device as shown in Fig. 1, Fig. 3 is a section taken on line 3-3 of Fig. 2, Fig. 4 is a perspective view of one of the brackets which support the steering device in position, Fig. 5 is a front elevation of one of the brackets, Fig. 6 is a view similar to Fig. 3 of a modified form of the invention,

Fig. 7 is a front elevation of the modified form showing the upper part of the steering mechanism removed, Fig. 8 is a sect-ion on line 8 8 of Fig. 6, and Fig. 9 is a frag mentary top plan view of the steering wheel proper showing the spark and gas control levers. Fig. 10 is a sectional view of a modified form of one of the brackets for supporting the modified form of steering device. Y

The invention as at present contemplated includes a base plate 1, on each end of which is mounted curved guiding blocks 2, the latter being adapted to engage chain 27. Preferably formed integral with the base plate 1, and depending therefrom is a collar 3, the collar being interiorly threaded so as to be in threaded engagement with thev 'arbor tube 4. A bearing sleeve 5 is secured in the lower end of the arbor tube 4 by means of a screw 6 which passes through collar 3, arbor tube 4, and extends partly into the sleeve 5, as shown in Fig. 2, whereby the arborI tube 4 is held rigid, with the bearing sleeve 5, which latter forms a bearing for the lower end of the longitudinal control handle tube 7. Fitted to rotate within the tube 7 is a second longitudinal control handle rod 8. A control foot 9 is secured to the tube 7 so as to rotate therewith, and a similar control foot 10 is secured to the rod 8 so as to partake of the movements thereof, it being understood that these control feet govern the spark, that is to say, one of the feet controls the spark and the other controls the gas, the spark control being for the purpose of advancing and retarding the spark and the gas control or throttle that of the gas, as is understood by those versed in the art of gas engines. p

A sprocket wheel 11 surrounds the stationary arbor tube 4, and is rotatable with respect thereto, the sprocket wheel being formed with an upwardly extending externally threaded annular flange 12, which is in threaded engagement with the outside tube 13, the upper end of tube 13 rigidly carrying the steering wheel 14. A common sector 15 is rigidly carried by the steering wheel 14 and is provided on its opposite sides with depressed seats 16 as seen in Fig. 9. A lever 17 is rigidly secured to the upper end of rod 8 and is formed in its outer end with a hollowed out portion in which a small coil spring 18 is mounted, the outer end of the `coil spring exerting pressure against a ball 19,`which latter is adapted to engage in one of the seats 16, it being understood that the pressure of the spring 18 can be readily overcome by manual movement imparted to the lever 17. Similarly a second lever 20 is rigidly secured to the upper end of thel tube 7, leverr20 being equipped with a similar spring pressed ball which latter however engages the seats 16 formed in the periphery of the sector 15, as distinguished from the spring pressed ball of the lever 17 which engages the seats in the inner surface of the sector 15. By reference to Fig. 2 it will be observed that the base plate 1 is formed with downwardly extending perforated ears 21, which latter are adapted Vto-'be received in thebifurcated end carried by the arm 23 of the bracket member 24. As shown in Fignllofthe drawings bracket 24 is suitably 'secured to' the front board of the boat in any approvedv manner, and the bifurcated end 25 is formed with a perforation adaptedto aline with the perforation in ear" 21, a securing thumb screw 26 being p'assedthrough the aliningy perfo# rat-ions whereby the furcations may be clamped into engagementwith the ears 21 to thereby hold the steering mechanism in any desired angular position', one of the positions being lllustratedl in Fig. 1 of the drawings.A l

A chain 27 engages with 'sprocket 11- and between the flanges of the guide' rollers 2, thechain having its ends connected with the rudder in a manner well known and familiar lto those versed in the art.` i I A modification is illustrated in Figs. 6, 7, 8 and 10, in which the base plate 1 is provided with curved bearing blocks 2 and lugs 2 vwhich together serve as a means to 'support the cover plate 4.V In this form of the invention the base plate is cast or otherwise formed with hollow turnnions 3 through which the ends of the sprocket chain pass. In cases where the trunnions 3 are employed, the ears 21 may be dispensed with or entirely omitted from the' base plate land the trunnions held' in bracket ineinbers 26 shown in Fig. 1Cor the drawings, the bracket 26 being bifurcated and formed with an annular seat 2'53 in which the trinnions are held byniea'n'sr of a thumb It will thus be observed that the spark control and the throttle ar'enbdied in the steering wheel proper, confining allv the to a small sphere within convenientand ready reach of the operator.

' What I claim is' i 1. A steering mechanism `for', motor boats, including a. base plate formed with downprojectinglr perforated ears, a steering wheel supported from the basepla'te,
