Description

May 18, 1965 R. c. HEIDNER SPEED CONTROL nEvI cE Filed Feb. 23, 1962 INVENTOR.
United States Patent 3,183,879 SPEED CONTROL DEVICE Richard C. Heidner, Libertyville, Ill., assignor to Outboard Marine Corporation, Waukegan, BL, 21 corporation of Delaware Filed Feb. 23, 1962, Ser. No. 175,087 8 Claims. (Cl. 115-18) The invention relates generally to engine speed or throttle controls and, more particularly, the invention relates to arrangements for controlling the speed or throttle setting of an engine, such as for example, an internal combustion engine or an electric motor, driving a maneuverable vehicle.
With respect to vehicles such as boats driven by internal combustion engines, and with particular respect to boats driven by outboard motors, certain of such boats can be capsized by sudden advancement of the throttle when the steering mechnaism is set for a relatively sharp turn. The control disclosed herein avoids this hazard by preventing advancement of the engine throttle from below to above a predetermined setting when the steering mechanism is disposedto effect turning of the boat at a rate above a preselected amount. The disclosed embodiment is incorporated in an outboard motor and includes a cam track on the swivel bracket in position to displace a follower which is carried by a dirgible propulsion unit and which is adapted to effect control of the throttle setting mechanism.
Because the danger of capsizing is not generally present if a boat is turned sharply after the engine has been advanced to full speed, the disclosed embodiment includes a linkage, between the follower and the throttle control member, incorporating an arrangement affording, when the throttle is advanced beyond the predetermined setting, movement of the linkage components relative to each other without affecting steering of the boat or the throttle setting of the engine.
Other advantages of the invention will become apparent by reference to the following description and the accompanying drawings of one embodiment in which:
FIGURE 1 is an elevational view, partially broken away and in section, of an outboard motor embodying various of the features of the invention; and
FIGURE 2 is an enlarged, somewhat diagrammatic view, partially in section, illustrating the throttle control arrangement embodied in the outboard motor shown in FIGURE 1.
The throttle control arrangement 11 shown in the drawings limits the setting of an engine throttle when an associated steering arrangement is in a turning disposition. Although the arrangement 11 is embodied in an outboard motor 13 mounted on the transom 15 ofa boat 17, the principles of the invention are not restricted to control of the setting of an outboard motor throttle.
The outboard motor 13 conventionally includes a transom bracket 19 which is releasably fixable to the transom 15, a swivel bracket 20 which is carried by the transom bracket 19 for pivotal movement about a horizontal axis or pivot 22, and a propulsion unit 21 which is carried by the swivel bracket 20 for pivotal movement relative thereto about a generally upright axis or swivel 24 in order to steer the boat. The propulsion unit 21 conventionally incorporates a powerhead or engine 23 which may be either an internal combustion engine or an electric motor, which engine is connected through power transmission means (not shown) to a propeller 26. The engine 23 includes a throttle (not shown) which is adjustable by a throttle control member 25 (see FIGURE 2) to control the speed of the engine.
Limitation of the throttle setting, incident to shifting of the propulsion unit 21 from a position affording straight-ahead movement of the boat, is provided by linkage means 27 including a cam track 29 on the swivel bracket 29. Engaged by the cam track 29 is a follower 31 which is carried by the propulsion unit 21. Also included in the linkage means 27 is a cam 33 mounted on the throttle controlling member 25 which, in the disclosed construction, is axially rotatable, to control the throttle, and a sub-linkage 35 connected to the follower 31. Included in the sub-linkage is a portion 37 which is normally disposed by the follower 31 in position for interfering engagement with the cam 33 to prevent subsequent increasing of the throttle setting from below to above a predetermined value when the propulsion unit 21 has been shifted from its position affording straightahead movement of the boat.
More particularly, the cam track 29 extends along an arc defined by the follower 31 incident to shifting of the propulsion unit 21 about its upright axis. The cam track 29 includes a central portion 39 which affords shifting of the propulsion unit through a limited central range extending on both sides of its straightahead position without disabling setting of the throttle through a full range of speeds. Also included in the cam track are relatively raised portions 41 extending from each side of the central portion, which raised portions 41 serve to actuate the follower 31 to limit increasing of the throttle setting beyond a predetermined level. The follower 31 is vertically slidably carried for engagement with the cam track 29 in a guideway 43 in the engine cover 45 of the propulsion unit 21.
The throttle control member 25 is rotatable, in the disclosed construction, in a counterclockwise direction to advance the throttle setting and the cam 33 carried thereon includes a radially projecting lug or lobe 47 having an abutment surface 48 which is horizontally disposable incident to rotation of the cam 33 for engagement by the sub-linkage portion 37 to prevent counterclockwise rotation of the control member beyond a predetermined throttle setting. More specifically, the sub-linkage 35 includes a bell crank lever 4-9 which has one arm connected to the follower 31 through a horizontal lost motion connection, indicated at 50, and is biased by a spring 51 to retain the follower 31 in engagement with the cam track 29. Connected to the other arm of the lever 49 is a bar or rod 53 which is supported at 55 and 57 by the engine cover 45 and is shiftable by the lever 49 to position the portion 37 relative to the cam 33. Thus, when the throttle is initially set below said predetermined value and the follower 31 is then engaged with either of the raised portions 41 of the cam track 29, the sublinkage portion 37 is positioned for interference with the abutment surface 48 of the cam lobe 47 to prevent increasing the throttle setting beyond said predetermined value. I
The sub-linkage 35 is also arranged to permit shifting of the propulsion unit 21 from its central range of positions when the throttle setting is above said predetermined value. In this regard, the rod 53 includes two telescopic sections 59 and 61 which are movable relative to each other to afford movement of the sub-linkage portion 37 relative to the cam 33 on the throttle control member. The connection of the telescopic sections 59 and 61 includes means in the form of a spring 63 biasing the sections 59 and 61 away from each other. Accordingly, the spring permits movement of the telescopic sectended condition for interfering engagement with the cam lobe 47.
