March 16, 19 4 G. L. MCCARTNEY INJECTOR-EJECTOR ATTACHMENT FOR OUTBOARD MOTORS Filed July 27, 1951 INVENTOR.

GEOFFREY L. M CARTNEY ATTORNEY w .1.. .1 My iriv'ention relates to boat "cleaners generally,; but more inparticular" to an;injectoreietor typeiboat cleanerwhich" uses thefforce of water moving through" the same either to bring water into the boat or-toremove water from theboa't Inmy oo-pending" application, Serial No; 199,439513 havedescribed-andclaimed a"devic'e similar to that of the present invention but which requires actual movement of the boat through the water for its operation. Moreover, such device is arranged for clamping to the side or gunwale of a boat, whereas that of the present application is adapted for attachment to an outboard motor used on the boat.

It is an object of the present invention to provide an injector-ejector type boat cleaner arranged for attachment to an outboard motor used on a boat, the cleaning device being operable by moving water to force water'either into or out of the boat at the will of the operator.

It is another object of the invention to provide such a boat cleaner which is operable to inject water into a boat or to remove water from the same, irrespective of whether or not the boat is actually in motion.

It is another object of the invention to provide an automatic pump and syphon, operated by the water in which the boat is placed, to draw accumulated Water from the inside bottom of the boat or to bring in other water for cleaning the boat at the will of an operator.

A further object of the invention is to provide such a pump and syphon mechanism which utilizes the force of the water moved by the motor on the boat for both injecting water into the boat and for ejecting water therefrom.

Other objects and advantages of the invention will become apparent in the course of the following detailed description of the invention when taken in connection with the accompanying drawing in which:

Fig. 1 is a cross-sectional view illustrating an embodiment of my invention in an injector-ejector boat cleaner, the same being shown as attached to an outboard motor.

Fig. 2 is an end view of the device shown in Fig. 1.

In the drawing, numeral 10 designates generally the stem end of a common fishing boat.

Clamped to the transom ll of the boat is a conventional outboard motor I 2. Attached to the drive shaft housing of the motor I2 are upper and lower brackets I 3 and M. The inner ends of both brackets encircle the housing and are clamped by means of bolts I5 and l6.

Q Q h W L i i re arranged. to, support a tubular body member designated generally; by the numeral I1. straight shank portionJl8 of the tube I7 is pro-. vided withwearbushings l9 and 26 around which the outersendsof the respective brackets l3 and M are rotatably mounted. Since the shank I8 is thus rotatably mounted with respect to the brackets, the entire tube I! may be turned to any radial setting and locked in such setting by means of a wing nut 22 which squeezes the circular end of the upper bracket I3 against its bushing I 9.

At the lower end of the shank I8, I have provided a curved portion in the tube l1 which terminates in a funnel shaped mouth 23. The upper end of the shank portion [8 is also bent as shown and adapted to receive a length of rubber hose 24. Since the tube I1 is supported by the brackets in a vertical plane with that of the motor on which it is mounted, the mouth 23 is held in alignment with the propeller 25 of the motor l2 whether the same is turned toward or away from the propeller, the reverse position of l the tube being shown in dotted lines in Fig. 1.

The simplicity of the apparatus now becomes apparent. When the mouth of the tube I1 is placed toward the propeller it is in position to receive the force of the water moved by the propeller, such force being sufiicient to move the water upwardly through the shank l8 and rubber hose 24, and into boat II]. It is also apparent that in such construction, the boat itself does not necessarily have to be moving in the water but may be anchored against such movement, allowing the motor to operate the device as described. The hose 24 may be used not only to admit water into the boat for cleaning, but may also be used to spray down the inside of the entire boat and thus lighten the job of cleaning.

As before described, and as denoted by the dotted lines of Fig. 1, the tube may be turned to the reverse position with the funnel mouth 24 thereof facing away from the propeller 25. The force of the water, moved by the propeller 25 by-passing the funnel 24, causes sufficient suction through the hose 24 and tube 11 to drain all the water previously pumped into the boat for cleaning. As in the former instance, the boat itself may be anchored against any movement in the water, while the actual operation of draining may be accomplished by means of the motor I 2.

As shown in the drawings, the diameter of the funnel-shaped mouth 24 of the tube 11 is thej'bra'ckets l3 and 14.

The

slightly less than the diameter of a circle described by the revolving propeller of the motor 12. By keeping the mouth 24 to such a restricted diameter, any submerged object which might otherwise damage the device if encountered in the water, is made to strike the propeller guard first. Moreover, since the mechanism is attached to the motor itself, it presents no installation problem when placing the motor 12 upon any boat for use.

While I have described my invention in a particular embodiment it is to be understood that this has been by way of example only and that other changes in construction may be made without departing from the scope of the invention as defined by the following claim.

I claim:

In combination with a propeller driven outboard motor boat, injector-ejector apparatus for cleaning said boat comprising, a tube disposed substantially vertically at the stern ofsaid boat, brackets attached to said motor and adjustably supporting said tube, said tube having a lower open end disposed horizontally and provided with a funnel-shaped mouth, a flexible hose attached to the upper end of said tube of sufficient length 4 to extend past said motor and into the bottom of the boat, means for locking said tube in a forwardly directed position where water moved by said propeller is directed into the open-ended mouth of said tube and through said hose and into the bottom of said boat, and means for reversing and locking said funnel-shaped mouth in a rearwardly directed position so that water moved by said propeller creates a suction in said tube to withdraw water from said boat, said tube having a U-shaped bend adjoining said funnel shaped mouth to position said mouth in substantially the same vertical plane for both the forwardly directed position and the rearwardly directed position.
