Definitions

  • the invention relates to outboard motors. More particularly, the invention relates to outboard motors including propulsion units which are principally located rearwardly of a boat transom and which are dirigible or horizontally swingable to afford steering and which are vertically swingable to afford passage over underwater obstacles.
  • An outboard motor in ⁇ accordance with the invention includes means for supporting a propulsion unit from a boat transom comprising a bracket assembly adapted to be attached to the boat transom, a yoke or dirigible bracket, pivot means connecting the bracket assembly and the yoke for horizontal swinging movement therebetween when the bracket assembly is attached to the boat transom, and pivot means connecting the propulsion unit and the yoke for vertical swinging movement therebetween when the bracket assembly is attached to the boat transom.
  • the steering axis is stationary and the propulsion unit is tiltable relative thereto.
  • means are provided for adjusting the angle between a transom bracket or tting and the vertical steering axis in order to accommodate it to boat hulls having transoms extending ⁇ at different angles.
  • the steering axis passes through the gear box in the lower unit when the propulsion unit is in its normal operating position.
  • the horizontal pivot between the propulsion unit and the dirigible yoke or bracket is located above the center of gravity of the propulsion unit. This arrangement results in the weight of the motor acting in opposition t-o vertical swinging of the outboard motor occurring in response to the hitting of an underwater obstacle.
  • the horizontal pivot is also located with respect to the center of gravity so as to be located at least as far forwardly as the center of gravity.
  • the vertical pivot is located aft of the Iboat transom to which the outboard motor is attached, and the horizontal pivot is connected to the power head, above the top of the vertical pivot, and aft of the front of the power head at a horizontal distance which is less than the vertical distance between the top of the vertical Ipivot and the horizontal pivot.
  • the horizontal pivot is provided on a pair of horizontally spaced legs on the dirigible yoke and is located at a vertical distance above the top of the vertical pivot which is greater than the horizontal distance from the front of the power head to the horizontal pivot.
  • the outboard motor As the outboard motor is principally located aft of the transom, and the vertical swinging movement of the outboard motor does not involve substantial displacement forwardly of the boat transom, the outboard motor will not fall into the boat if the outboard motor breaks away from the transom after hitting an underwater obstacle.
  • the steering connection to the outboard motor has little or no vertical swinging movement, thereby simplifying boat construction and control connection.
  • FIGURE l is an elevational view, partially in section, of an outboard motor which embodies various of the features of the invention and which is shown mounted on ⁇ a boat transom in a generally upright operating posltlon;
  • FIGURE 2 i-s a view similar to FIGURE 1, showing the outboard motor in an elevated position;
  • FIGURE 3 is a fragmentary rear elevational view of the outboard motor shown in FIGURE l;
  • FIGURE 4 is a view, partially broken away and in section, taken generally along line 4-4 of FIGURE 1;

  • the propulsion unit 13 is generally of conventional construction and includes a
  • Supported within the power head is a prime mover (not shown) which is commonly in the form of an internal combustion engine.
  • the lower unit supports a gear case 20, a propeller 21 or other thrust producing element, and a drive train which connects the propeller 21 to the engine and which commonly includes, in the lower unit 19, a driveshaft 22 (see FIGURE 4), and clutch means (not shown) affording neutral, forward drive, and rearward drive operation.
  • the means 15 for supporting the propulsion unit comprises generally a transom bracket assembly 23 adapted for connection to the boat transom 16, a dirigi'ble yoke, member, or bracket 25, pivot means connecting the yoke 25 and the transom bracket assembly 23 for swinging movement about a generally vertical axis, and pivot means connecting the propulsion unit 13 to the yoke 23 for swinging movement of the propulsion unit 13 about a generally horizontal axis.
  • the transom bracket assembly 23 can be adapted to be connected to the boat transom 16 in various ways and includes a member or support 27 mounting one or more vertical bearings 29, together with means affording adjustment of the member 27 to locate the propulsion unit 13 at its optimum position for boat propulsion, notwithstanding variation in transom angles of different boats.
  • the transom bracket assembly 23 includes a pair of fittings 31 and 33 which can be constrncted in general accordance with the fittings identified by numerals 8 and 9 in the United States Conover Patent 3,061,250, issued October 30, 1962.
  • Telescopically receivable in the fittings 31 and 33 is a member or bracket 35 which can be constructed in general accordance with the construction of the transom bracket 20 identified in the Conover Patent 3,061,250.
  • the bracket 35 comprises a pair of laterally spaced portions 37 each including, in the upper part thereof, an upper transverse bore 39 and, adjacent the lower part thereof, an arcuate series of apertures 41 located at common radii from the transverse bore 39.
  • the member or support 27 can be constructed in various ways to provide the aforementioned vertical bearings and to afford angular adjustment of the upright bearing axis with respect to the boat transom 16 to which the bracket assembly 23 is attached.
  • the member 27 comprises a sleeve 43 having therein the vertical bearing 29. Adjacent its upper end, the sleeve 43 is integrally connected with an upper transverse part 47 having therein a bore 49 receiving a shaft or pintle 51 which also passes through the upper bores 39 in the bracket portions 37. This connection of the member 27 to the bracket 35 by the pintle 51 affords angular movement of the member 27 relative to the bracket 35 in a Vertical plane.
  • the sleeve 43 Adjacent its lower end, the sleeve 43 is integrally connected to a second or lower transverse part 53 which also includes a bore 55 therein.
  • the bore 55 is spaced from the bore 49 at a distance which corresponds to the spacing between the apertures 41 and the bore 39 in the bracket portions 37. Accordingly, the bore 55 is alignable with the apertures 41.
  • vertical swinging of the member 27 relative to the bracket 35 is releasably prevented by a removable locking bolt 57 which passes through an aligned pair of apertures 41 and through the bore 55.
  • Suitable means can be provided to prevent accidental displacement of the locking bolt 57 from its position releasably preventing relative angular movement between the bracket 35 and the member 27.
  • the previously mentioned means for vertically adjusting the angular relationship of the member 27 to the bracket 35 comprises the pintle 51 and its associated bores 39 and 49, and the locking pin 57 and its associated bore 55 and apertures 41.
  • the yoke 25 which is shown best in FIGURE 6, can be constructed in various ways and includes one or more vertical bearings and a pair of horizontal bearings.
  • the yoke 25 comprises a U-shaped upper portion 61 including a generally horizontal web 63 and a pair of vertically extending legs 65. At their upper ends, the legs 65 each respectively include the horizontal bearings 67.
  • a stem portion 69 which, in horizontal cross section, is of generally U-shaped formation. Extending forwardly from the bottom of the base of the U-shaped formation is an arm 71. Located respectively adjacent the forward end of the arm '71 and in the web 63 are :aligned vertical bearings 73 and 75. Carried at the forwardmost part of the web 63 in spaced relation to the bearings is a fitting 77 adapted to be connected to a steering control.
  • the pivot means for connecting the yoke 25 and the transom bracket assembly 23 for swinging movement of the yoke 25 relative to the bracket assembly 23 about a generally vertical axis comprises, in addition to the before described bearings 29, 73, and 75, a kingpin 79 (see FIG- URE 4) extending through said bearings.
  • the pivot means connecting the yoke 25 and the propulsion unit 13 comprises, in addition to the horizontal bearings 67, a pair of pivot pins 81 which respectively project through the horizontal bearings 67 :and extend from respective supports 83 on the power head 17.
  • the supports 83 are located on the power head 17 above the center of gravity of the propulsion unit 13 and either in a vertical plane containing the center of gravity or forwardly of the center of gravity.
  • the center of gravity is identified by the numeral 85 in FIGURE l.
  • This arrangement has the advantage of employing the weight of the engine in opposition to vertical swinging of the propulsion unit 13 in response to the striking of an underwater obstacle.
  • the center of the supports 83 is also preferably located substantially rearwardly of the forward end of the power head 17, but at a distance from the forward end of the power head which is less thanthe distance between the web 63 and the horizontal axis defined by the bearings 67.
  • Locating the supports 83 thusly permits the forward end of the power head 17 to swing downwardly and between the legs 65 of the yoke 25 and not through a path extending substantially forwardly of the boat transom 14, as has commonly been the practice in the past.
  • the horizontal axis defined by the bearings 67 - is spaced from the top of the kingpin 79 at a vertical distance which is greater than the horizontal distance therebetween.
  • Such means connects the yoke 25 and the lower 'unit 19 and can be arranged in a manner similar to that disclosed in the United States Patent Re. 25,048, issued October 3, 1961. More specifically, such means is shown fragmentarily in the drawings as including a forwardly and downwardly projecting portion 87 which extends from the yoke arm 71 and includes a transverse shaft 89 corresponding to the bar 30 disclosed in said Hulsebus patent. Extending from the propulsion lower unit 19 are a pair of hooks 91 which correspond to the hooks 50 disclosed in said Hulsebus patent.
  • shock absorbing means connected between the yoke 25 and the propulsion unit 13 for cushioning vertical swinging movement of the propulsion unit 13 in response to the striking of an underwater obstacle.
  • such means is in the form of one or more hydraulic shock absorbers 93 which are pivotally connected, at one end, to the inside of the yoke legs 65, at a point adjacent to the web 63.
  • the shock absorbers 93 are pivotally connected to the power head 17 at points below the pivot pins 181 and so that the shock absorbers 93 will not contract during any part of the upward swinging movement of the lower unit 19 in response to the striking of an underwater obstacle.
  • the connection of the shock absorbers 93 to the power head 17 is located vertically below the horizontal pivots 81.
