Since it has become the requirement of outboard motor operators that the motors exhaust 20 under water, it has become necessary to run an exhaust pipe parallel with the drive shaft housing and spaced therefrom. Such construction makes it impossible to mount the motor so that the same may swing throughouta complete revo.- 25 lution where rotationis had about the axis of the drive shaft housing and thus be used for propulsion in either direction. The present invention provides a construction whereby a motor of such characteristics may be mounted so as to make a complete revolution whereby the desired advantages may be procured.

For the purpose of illustrating the application of my invention I have shown in Figs. 1 and 2 a portion of a boat l0. Inasmuch. as the invention does not lie in the boat only a portion of the boat has been illustrated. The part of the boat illustrated consists of a transom Il to which is attached a keel l2. A knee I3 is disposed between the transom and keel. The boat also in- 40 cludes a plankng I4 which is attached to the transom il and which forms the sides of the boat together with plankng l5 which is attached to the lowermost portion of the transom Il and to the plankng I4 to form the bottom of theyboat. 45 A seat i6 carried on stringers i1 is provided at the rear end of the boat.

The outboard motor used with my invention may be of any of the conventional types such as are now in common use and Asince the invention does not reside in the specic construction of the motor proper, the same has only been generally illustrated. The outboard motor is indicated by the reference numeral 2l and consists of a power 55 table 35.

unit 22 including one or more cylinders and pistons and corresponding connecting rods operated thereby but-not shown. The connecting rods of the motor are connected to a crank shaft not illustrated which may be directly connected to a. drive shaft-23 or which may be integral therewith. The shaft 23 is mounted for rotation with- /in a drive shaft housing 24 which is tubular in form and which is attached at its upper end to the power unit 22. The lower end of the housing 24 has secured to it a gear housing 25. Within this housing are bevel gears, not shown, one of which is driven by drive shaft-23 and the other which drives the propeller shaft 26. Shaft 26 has secured to it a propeller 21. vThe upper end of the crank shaft or the shaft 23 as the case may be has secured to it a. y wheel 28. A fuel tank 29 extends about the ily wheel. Attached to the power unit 22 is a steering lever 30 which has mounted on the end of it a handle 3| by means of which the entire outboard motor may be` rotated to steer and reverse the direction of propulsion of the boat as will presently become apparent.

The exhaust from the power unit 22 is carried through an exhaust pipe 36 which is connected at its upper end with the exhaust ports of the outboard motor and which is attached to its lower end to a muilier 31 carriedby gear housing 25 and adapted to discharge below the water level. In the housing 25 is provided a pump 38 by meansof which water is pumped through a pipe 39 and into the Water jackets of the cylinders of the power unit 22 and subsequently discharged therefrom. The two

pipes

36 and 39 lie parallel with the drive shaft housing 24 and disposed in eccentric relation thereto'and spaced therefrom.

My invention comprises aclamp 32 to which is attached a mounting 33. Mounting 33 carries a bracket 34 which rotatably supports a turn The drive shaft housing 24, the exhaust pipe 36 and water pipe 39 all pass through the turn table 35 and the entire outboard motor is supported on this turn table. 'I'hese various parts will now be described in detail.

The clamp 32 is C-shaped in form, being constructed with spaced vertical legs 4| and 42 and a connecting portion 43 therebetween. These portions are T-shaped in cross section and have flanges 44 and webs 45 extending outwardly therefrom. 'I'.he flange 44 of the leg 42 is adapted to rest against the rear surface of the upper portion of the transom of the boat I0. 'I'he lowermost portion of the leg 4| is formed with a boss 49 which is threaded to receive an adjusti`ng screw 5|. This screw carries a swivelly attached head 42 which is adapted to engage against the inner surface of the transom and when the said screw is rotated by means of handle 53 the clamp is urged into engagement with the transom. The flange 44 of leg 42 is of considerable width so that a sufficient bearing surface is provided to securely attach the clamp to the boat.

The mounting 33 is anguular in form and is constructed with two

legs

54 and 55. The leg 54 is arranged horizontallywhile the leg 55 is arranged vertically and depends` from one end of the leg 54. Bothof these legs are U-shaped in cross sections being constructed with flanges 56 and a web 51 therebetween. The mounting 33 is disposed so that-the flanges 56 thereof straddle the web 45 of the leg 4| of clamp 32. 'I'h'e mounting 33 is pivoted to the clamp 32 by means of a bolt 58 which extends jointly through the two va ball 16 which is recesses 83 and 84 flanges 56 of the mounting 33 and the web 45 of the said leg of clamp 32. This bolt is disposed at the free end of the leg 54 of mounting 33 so that when the said mounting is swung about the bolt 58 as a pivot the angular position of the mounting is varied with respect to the boat.

At the lower end of is provided a boss 59 the leg 55 of mounting 33 which is threaded to receive a screw 6|. This screw engages the web 45 of the leg 42 of clamp 32 and serves to shift the angular position of the mounting. A handle 62 carried by this screw permits of readily adjusting the same.

Issuing outwardly from the leg 55 of mounting 33 is a bracket 63. 'I'his bracket is in the shape of a plate and is constructed annular in form being provided with a circular opening 64 extending completely through the same. By 'means of this opening two

annular shoulders

65 and 66 are formed on the said bracket 63 which are at right angles to the axis of the opening 64 and which form a track extending circularly about the said opening. The bracket 63 is attached to the leg 55 at a locality above the screw 6| so as not to interfere with the operation thereof.

Rotatably mounted on the track formed by the

shoulders

65 and 66 is a turn table 61 which comprises a disc 68 rotatably mounted within the circular opening 64. This disc is constructed with a ange 69 extending outwardly therefrom and which rests upon the shoulder 65. The disc 68 is of such thickness that the lowermost surface 1| thereof lies flush with the shoulder 66. Attached to the disc 68 is a plate 12 which is of substantially the same size as the flange 69 of said disc and which engages the lowermost shoulder 66 of the bracket 63. 'I'he plate 12 is attached to the disc 68 by means of screws 13 which extend through the said disc and are threaded into the plate. It will readily be comprehended that the turn table 61 becomes rotatably mounted for movement along the track of the bracket 63 and may make a complete revolution with respect thereto.

For the purpose of arresting the turn table 61 in certain positions the following construction is employed. Formed in the bracket 63 is a bore 18. A screw 15 is threaded into the outer end o-f this bore. Within this bore is mounted urged into engagement with a number of sockets 11 in the disc 68. A compression coil spring 14 seated at one end against the ball 16 and at its other end against the screw 15 holds the ball in operative position. The sockets 11 are of such shape that the turn table 61 is held in proper position but may be released upon the exercise of sufficient force to the handle 3|.

The outboard motor of the invention is carried by the turn table 61 and is attached thereto in the following manner: 'Formed in the disc 68 and in the plate 12 is `an opening 8| of such dimensions as to snugly receive the drive shaft housing 24, the exhaust pipe 36 and the water pipe 39. In the particular type of outboard motor shown, the air intake 82 of the motor extended to a position in proximity to the locality where' it was desired to attach the turn table to the motor. To accommodate this intake, the opening 8| was constructed accordingly as shown in Fig. 3. The opening 8| is formed with two in which the housing 24 and the pipe 36 t;

Sleeves

81 and 88 mounted upon the housing 2l and the pipe 36 engage the power unit 22 and support the entire structure through the disc 68. Two collars 89 and 9|. provided with set screws 92, are mounted on the housing 24 and pipe 36 and engage the under side of the plate 12 and hold the parts rigidly attached to the turn table 61.

In assembling the motor on the support the gear case 25 is removed whereupon the

sleeves

81 and 88 may be assembled upon the housing 24 and pipe 36. Thereafter the parts may be inserted in the proper position within the hole 8| of.disc 68 and plate 12 and the collars 89 and 9| applied to said housing and pipe. After these collars are secured in place .through the set screws 92 the gear case 25 is again applied and the outboard motor is ready for use.

The use of my invention is as follows: After the clamp 32 has been applied, screw 6| is used for adjusting the angularity of the propeller 21 with respect to the surface of the water. The outboard motor is then steered in the customary manner through the' handle 3| by rotating the entire motor through the turn table 61 and the track formed in the mounting 33. Whenever it becomes desired to reverse the travel of the boat the entire outboard motor is completely turned around through an angle of 180 degrees until the same occupies the position shown .in Fig. 2. This may b e accomplished without stopping the motor. When it is desired to run the motor continuously, in a directly forward direction, the motor is shifted until the ball 16 engages the proper socket 11 which affords suiiicient frictions to maintain the motor in the desired adjusted position.

The advantages of my invention are manifest. An extremely simple and practical construction is provided wherebyvan outboard motor having an under water exhaust may be turned throughout a complete revolution so that the motor may be used to propel the boat either in a forward or rearward direction without reversing the motor. My device operates in an exceedingly effective manner. My invention can'be used with various types of outboard motors and without reconstruction thereof. With my invention adjustment of the angularity of the propeller with respect to the surface of the water can readily be made while the motor is in operation.

Changes in the specific form of my invention, as herein disclosed, may be made within the scope of what is claimed without departing from the spirit of my invention.
