Hart, St. Paul, Minn, assignor to McCulloch (Jorporation, Los Angeies, Qalih, a corporation of Wisconsin Filed Aug. 28, 1962, Ser. No. 219,854 s Claims. (Cl. 248-4) This invention relates generally to the mounting of an outboard motor on a boat transom and more particularly concerns a motor mounting structure for positioning the motor at various elevations and various angles of tilt relative to the transom.
To obtain optimum performance from an outboard motor under all operational conditions, where speed and power requirements might vary considerably, it is desirable that the motor or at least the propeller thereof be adjustable between various elevations and various angles of tilt. In the past where such adjustment means have been used, vertical and tilt adjustment have been accomplished by separate devices. In other words, there are many well known mechanisms for raising and lowering the motor relative to the transom on which it is mounted. By the same token, there are many known constructions for adjusting the tilt or trim of the motor relative to the transom for maximum performance. Moreover, both such lift devices and tilt devices have lent themselves to control or operation from a remote point.
It is an object of the present invention to combine the advantages of such devices by providing a mounting system for an outboard motor which when operated to raise or lower the motor will, without further effort, automatically adjust the motor to the proper tilt angle for maximum performance at the selected elevation.
Another object of the invention is to provide a new and improved combination power lifting and tilting mounting system for an outboard motor which can be utilized with only minor modifications in the conventional outboard motor construction and which does not in any way interfere with normal operation of the standard motor reverse lock or with free upward swinging of the motor in the event the lower unit thereof engages an underwater obstacle.
With these objects in view the invention broadly comprises a bracket means adapted to be permanently mounted on the boat transom, a pair of trunnion members pivoted on the bracket means on a common axis parallel with the transom, a motor support frame adapted l to support the motor and having portions slidable in said trunnions for up and down movement of the frame and motor, selectively extendable and contractible power means extending between the frame and transom for effecting said up and down movement, and a guide means slidably interconnecting the frame and transom below said axis for tilting the frame and motor carried thereby forwardly about said axis as it is raised and rearwardly about said axis as it is lowered to thus obtain maximum efficiency from the motor propeller at any selected motor elevation.
The above mentioned and still additional objects of the invention will be brought to light during the course of the following specification, reference being made to the accompanying drawings, in which- FIG. 1 is a side elevation of the motor mount with the motor in a lowered operative position.
FIG. 2 is a side elevation of the mount with the motor in a raised operative position.
FIG. 3 is an enlarged rear elevation of the mount with the motor removed taken along line 33 of FIG. 1 and looking forwardly.
FIG. 4 is a plan view of the mount with the motor removed and with the tilt pin partially broken away to show the mount lower structure.
Referring now more particularly to the drawings, reference characters will be used to denote like parts and structural features in the different views. The letter T denotes the transom which extends transversely across the rear end of boat B. A conventional outboard motor 10 having a lower unit 11 carrying the motor driven propeller 12 is mounted on the transom T by a structure forming the subject of this invention and now to be described.
The mounting frame, designated generally at 16, can best be understood by reference to FIG. 13. A pair of transversely spaced vertical frame members 17 have forward extensions 18 at their upper ends extending over the transom T, and downwardly converging extensions 19 at their lower ends which are integrally joined by a cross plate 26*. The forward ends of the members 18 are joined by a cross bar 21. A pair of parallel slide rods 22 are integrally mounted one on each side of the frame 16, the rods being connected to the members 17 by upper and lower projecting elements denoted at 24 and 25 respectively.
A pair of brackets 26 are secured in transversely spaced positions to the transom T as by bolts 27. Each of these brackets carries a sleeve or trunnion 28 which is pivoted as by trunnion pins 29 between ears 3t) mounted in spaced relation on the bracket. The slide rods 22 at each side of frame 16 are respectively slidably disposed within the sleeves 28. Accordingly, the entire frame 16 is mounted in the sleeves 28 for up and down sliding movement and limited fore and aft tilting movement with the sleeves about the axis of the pins 29 which are in transverse alignment.
A bracket 34- having a pair of transversely spaced cars 35 is mounted on the front side of transom T at the lower central portion thereof. An extensible jack 36 extends between bracket 34 and a coupling 37 mounted on the cross bar 21 with the jack cylinder .38 pivoted as by pin 39 to the coupling and with the jack piston rod 40 pivoted as by pin 41 to the bracket. Fluid lines 42 and 44 lead to opposite ends of the cylinder from suitable pump and drain sources to selectively extend or retract the jackin a well known manner. It will be readily understood that the entire frame 16 will slide upwardly in sleeves 223 as the jack is extended and will. move downwardly as the jack is contracted.
An upright guide member 46 is mounted in transversely centered position on the lower back side of the transom T. This guide has a rearwardly extending center web 47 which has a cam track 48 extending along the rear edge which follows an arcuate path converging toward the transom in its downward extension.
At the lower end of the frame 16 a U-shaped thrust socket 50 is mounted on plate 20. This socket opens rearwardly to receive and seat the leading edge of the motor lower unit. A pair of ears 51 are mounted on frame 16 forwardly opposite from the socket th to extend forwardly on either side of track 48. Each of these ears pivotally carries a cam member 52 which engages the front and rear side of the track.
A reverse lock pin 54 extends crosswise between the parallel upright portions 17 of the frame 16 and a motor pivot pin 55 extends crosswise between frame portion 18 just above the cross bar 21. The motor it) is provided with a conventional upright steering pintle (not shown) which extends through and is journaled for rotary movement in the sleeve 57 with the upper and lower ends of the pintle being secured to vertically spaced brackets on the motor 10, the lower being denoted at 55$. Sleeve 57 is integrally connected to a motor support bracket 59 which extends forwardly from the sleeve with the forward portion thereof journaled on the pin 55.
The motor is accordingly in conventional manner turnable about the axis of sleeve 57 with the motor mounted pintle rotatable therein. Also the motor can be tilted forwardly to an inoperative position about the axis of pin 55. A manually releasable reverse lock hook 6th is pivoted to tube 57 as at 61 for engagement over the cross pin 54 to hold the lower unit against the seat 59 when the motor is operated in reverse.
Operation of the invention will now be understood. When it is desirable to operate the propeller deep for general purpose boating or for pulling relatively heavy loads such as a water skier or to gain speed quickly, the jack 36 is contracted to lower the frame 16 and the motor carried thereby to the position shown in FiG. 1. Here the motor is literally tucked under the boat using the thrust angle which tends to lift the boat toward a planing position on the water.
When a planing position has been reached maximum speed can be attained by extending the jack 36 raising the mounting frame and motor to the position shown in FIG. 2 or to some intermediate position. As frame 16 is elevated the members 52 will follow along the track 48 swinging the lower portion of the frame and motor gradually rearward away from the transom about the axis of the trunnion pins 29. Accordingly, the angle of the propeller thrust against the transom automatically decreases as the propeller is raised in the water. The cam track 48 is designed to diverge gradually from the transom in its upward extension and is preferably curved so that the tilting movement diminishes or actually terminates during the upper reach of the motor elevating movement.
The construction can be used without substantial modification of the motor as the frame 16 merely takes the place of the conventional boat bracket. The motor support bracket 59 and steering pintle tube 57 remain unmodified and the reverse lock need not be changed. It is also significant that the motor engagement with the thrust socket 50 distributes the motor thrust pressures against the transom.
While a hydraulic lift jack is here shown for moving the frame, it will be understood that other mechanically or electrically operated extension devices might be used with equal effectiveness. It is believed to be of considerable importance that the construction disclosed makes possible the disposition of the power means, for raising and tilting the motor, entirely within the boat thus saving it from water damage and making it easily accessible for operation or repair.
The motor mounting means disclosed accordingly economically and effectively carries out the aforementioned objectives.
It is understood that suitable modifications may be made in the structure as disclosed, provided such modifications come within the spirit and scope of the appended 4 claims.
