OTHO P 5A #70 A rromvs s 6% United tates TILTABLE OUTBOARD MOTOR MOUNT ATTACHMENT FOR BOATS The present invention relates to outboard motor mount attachments for boats, and particularly to such devices for elevating the outboard motor with respect to the boat.
The primary object of the invention is to provide an outboard motor mount attachment for boats by means of which the outboard motor can be elevated with respect to the boat by means of a remote actuator.
Another object of the invention is to provide in an outboard motor mount attachment for boats of the class described above means to counterbalance the weight of the outboard motor to assist in elevating the motor with respect to the boat.
A further object of the invention is to provide an outboard motor mount of the class described above which is pivotally secured to the boat and is swung to an inboard position while elevating the outboard motor.
A still further object of the invention is to provide an outboard motor mount attachment for boats of the class described above having a remotely controlled lock securing the motor in lowered position to retain the mount in lowered position during reverse movement of the outboard motor.
Another object of the invention is to provide an outboard motor mount attachment of the class described above which is inexpensive to manufacture, simple to attach to a boat, and which is efiicient in providing means for elevating the motor with respect to the boat.
Other objects and advantages will become apparent in the following specification when considered in the light of the attached drawings, in which:
Figure l is a top plan view of the invention attached to a boat shown broken away for convenience of illustration.
Figure 2 is a side elevation of the structure shown in Figure 1., with an elevated position of the outboard motor illustrated in dotted lines.
Figure 3 is a fragmentary perspective view of the lifting mechanism.
Figure 4 is an enlarged fragmentary longitudinal vertical cross-section taken along the line 4-4 of Figure 1, looking in the direction of the arrows.
Figure 5 is a fragmentary transverse vertical section taken along the line 5-5 of Figure 4, looking in the direction of the arrows.
Figure 6 is a fragmentary exploded rear perspective view of the mount showing the motor support plate and wear plate therefor.
Referring now to the drawings in detail wherein like reference characters indicate like parts throughout the several figures, the reference numeral 10 indicates generally an outboard motor mount attachment for a boat generally indicated at 11.
The boat 11 is of conventional design including a keel 12, bottom 13, seats 14, opposite sides 15, 16, and a transom 17.
The attachment 10 is secured to the transom 17 and includes a generally rectangular plate 18 reverted at its upper end to form a hook 19 which engages over the atent O w 2,916,009 Patented Dec. 8, 1959 iCfi upper end of the transom 17. The plate 18 is secured to the transom 17 by a plurality of bolts 20. The hook 19 on the plate 18 has a pair of spacedapart' ears 21 secured thereto and extending forwardly therefrom.
A pair of frame members generally indicated at 22 are arranged in laterally spaced parallel relation and each are formed of channel iron. The frame members 22 each have an upper horizontal portion 23, a rear vertical portion 24, a lower horizontal portion 25 arranged parallel to the horizontal portion 23, and a relatively short forward vertical portion 26 depending from the forward end of the upper horizontal portion 23.
The frame members 22 are connected by a generally rectangular mounting plate 27 extending between and secured to the rear vertical portion 24 of the frames 22 and by a transverse angle iron 28 connecting the forward ends of the lower horizontal portions 25. A channel plate 29 is secured to the rear of the mounting plate 27 by means of fastening elements 30 to provide means for spreading the thrust when in use.
The lower ends of the relatively short forward vertical members 26 are positioned on oppositesides of the ears 21 and are pivotally connected thereto by an elongated shaft 31 which is held in position by cotter keys 32.
A coil tension spring 33 has its rear lower end connected at 34 to the lower edge of the mounting plate 27 intermediate the opposite sides thereof. The upper forward end of the coil spring 33 is secured at 35 to the upper edge of the transom plate 18.
A cable 36 has its rear end connected to one of the rear vertical members 24 at 37 adjacent the lower end thereof. A pulley 38 is secured to the hook 119 of the transom plate 18 at the horizontal portion thereof adjacent one side edge thereof. The cable 36 is trained over the pulley 38.
A second pulley 39, see Figure 3, is secured to the bottom 13 of the boat 11 adjacent the transom 17 and the cable 36 is trained thereunder. A pair of pulleys 40 are journalled on the side 15 of the boat 11 and the cable 36 is trained under the lower one and over the upper one, as best shown in Figure 3.
A lever 41 is secured to the bottom 13 of the boat 11 for pivotal movement between a pair of ears 42. The cable 36 is connected at 43 to the lever 41 to permit the cable 36 to be moved longitudinally over the pulleys 38, 39 and 40 on movement of the lever 41. A conventional pawl and rack mechanism 44 is arranged to secure the lever 41 in adjusted position, and a hand release member 45 is pivoted on the lever 41 to release the pawl and rack mechanism 44 when it is desired to move the hand lever 41.
A vertical slide bolt 46 is arranged for vertical sliding movement on the transom plate 18 adjacent the lower end thereof and is secured thereto by a cleat 47. The lower end of the bolt 46 is shaped to engage over the transverse angle iron member 28, as seen in Figures 4 and 5, to secure the frame members 22 in the position illustrated in Figure 4 and to prevent accidental elevation thereof. A release cable 48 extends into the boat 11 to provide means whereby the bolt 46 may be released when it is desired to elevate the frame members 22. v
Referring now to Figure 1, diagonal braces 49 and 50 are illustrated extending from the forward end portion of each of the horizontal members 23 diagonally across to the rear end portions of the opposite horizontal member 23.
An outboard motor, generally indicated at 51, is mounted on the attachment 10 with the conventional clamp 52 thereof engaged over the mounting plate 27. The connection of the outboard motor 51 with the mounting plate 27 is identical to the connection of the outboard motor 51 with a conventional transom 17 in an ordinary boat.
In the use and operation of the invention, the motor 51 is secured to the mounting plate 27 as noted above, and the motor is used in the coventional manner to drive the boat 11. On reaching particularly shallow water, the motor 51 can be lifted to any desired amount so that the propeller 53 is raised to a point making it impossible to contact the bottom it the boat 11 has sufficient clearance to float thereover.
The cable 36 can be pulled a suflicient amount to cause the motor 51 to come to a horizontal position with the upper portion of the motor 51 inboard of the boat 11 to permit service to be performed on the motor 51 without necessitating its detachment from the mounting plate 27.
Obviously, the hand lever 41 can be, locked in any desired position so that the motor 51 can be used for driving the boat 11 so long as the propeller 53 is at least partially submerged. t
It should be understood, of course, that the bolt 46 is utilized to prevent the elevation of the motor 51 during reverse operation or backing of the boat.
Having thus described the preferred embodiment of the invention, it should be understood that numerous structural modifications and adaptations may be resorted to without departing from the scope of the appended claims. 7 7
