SPRAY PRODUCING SCOOP FOR WATER-BORNE OBJECTS Filed June 4, 1957 /9 Q /N|/ENTOR:

THOMAS B. MODINE ,4 TTOR/VEV United States SPRAY PRODUCING SCOOP FOR WATER-BORNE OBJECTS This invention relates to a novelty item for use with boats or like water-borne objects to create a streamof water. 1 7

It is an object of this invention to provide a means whereby a stream of water can be created when said means is attached and properly disposed with regard to a water-home object moving through Water.

Another object of this invention is to provide a means of the novelty type which can be readily and easily attached to the rear of a motor boat, the motor, water skis, or the like object, and which is inexpensive but yet'adjustable, and all for the purpose of creating a stream or spray of water directed high above and behind the object when the latter moves through the waters Another object of this invention is to provide a novelty which accomplishes the foregoing objects with said means being readily movable out of an operating position and into an inoperative position. I

Other objects and. advantages will become apparent 'upon reading the following description in light of the accompanying drawings, wherein:

Fig. 1 is a perspective view of a motor boat with the device of this invention attached to the rear thereof and showing the water stream created by said device.

Fig. 2 is an enlarged top view of the device shown-in Fig. 1 and viewed along the plane indicated by the line 22 of Fig. 3, and showing a fragment of the boat motor.

. is the device, generally designated 12, which constitutes the embodiment of this invention," and it will be noted that the device is attached by means of a bracket 13 to the boat motor 11 on the boat transom 14. The bracket 13 is shown attached to the motor 11 by means of the four bolts 15 to secure the bracket in a fixed-position. It should be further understood that the view assumes that the boat is moving forward through the water, and the device 12, therefore, creates the water stream or spray depicted to begoing upwardly and rearwardly of the boat. Of course, this device is of a novelty type, and it will be appreciated that such a stream or spray of water creates an extremely interesting, aswell as pleasant, view in addition to creating'the effect of high speed of the boat since, heretofore, only the boats of the hydroplane type have created a rear stream or spray due to their extreme high speed. It should be further understood that a pair of the devices or items 12 could be attached, one to each side 2,983,508 I Patented May 9, 1961,

Also, the device could be attached to water skis, surf boards, and other water-borne objects.

Fig. 2 shows a fragment of the motor 11, and it further shows'a mounting plate 16 to be provided with an arcuate .slot 17 and two spaced apart and rearwardly projecting pieces 18. It will also be noted that the extreme rear ends of the pieces 18 are each provided with a semi-circular opening 19, and Fig. 3 shows the opening 19 to extend the length of the pieces 18 such that the screw 21 can pass through the opening 19 and through the plate 16 to attach into the bracket 13. 'As will be more apparent hereinafter, the screw 21 is utilized as a retaining screw for mountingthet item onto the boat transom, and

it is also utilized as a pivot screw for the item. Similarly,

a thumb screw 22 passes through the arcuate slot 17 to thread into the bracket 13 such that the two screws 21 and 22 secure the plate 16 to the bracket 13, and it will now be apparent that loosening of the screw 22 will per- .mit the plate 16 to be pivoted about the lower screw 21 by virtue of the slot 17, and thus the plate 16 and the entire item 12 can be disposed in any selected tipped or pivoted position with respect to the longitudinal direction of the boat 10.

As mentioned, the pieces 18 are spaced apart, and the therefore, receive a flat piece or connecting arm 23 which extends to a position adjacent the bracket plate 16, at which pointa pivot bolt 24 passes through the pieces 18 and; of course, through the plate 23 to secure the latter to the mounting bracket and provide the pivot axis for the plate 23.v Another thumb screw 26 threads into one of the pieces 18 to abut the near side of the plate 23, as shown in Fig. 2, and to thereby retain the plate 23 in a fixed pivoted position by virtue of the abutting or clamping force of thenut onto the side of the plate 23. A member or scoop 27 is attached to the rear end of the plate 23 to move therewith, and it will be noticed that the scoop 27 includes a rear portion 28 and side portions 29 and afront portion or cross bar 31. The side portions 29 are shown to converge toward the upper end thereof and, of course,.there is no bottom portion, or it may be stated that the bottom of the scoop is open.

In the full line position shown in Fig. 3 the rear portion 28 presents an upwardly and rearwardly inclined surface, the lower end of which extends down intothe water andfbelow the surface line indicated Sfand shown by a dotdash line in Fig. 3. When it is desired to raise the scoop 27 out of the water, the thumb screw 26 can be loosened and the scoop with the plate 23 can be pivoted to the raised position with front edge of the plate 23 engaginga lower hole in the pieces 18, such as shown in Fig, 3, so that the net result is that the scoop 27 will be placed in the dot-dash line position shown in Fig. 3. In, the latter mentioned position, of course, the scoop 27 willnot create the stream or spray of water, such as indicated in Fig. 1, and the device is, therefore, in an inoperative position. Since the lower ends of the sides 29 are farther apartthan the upper ends of the sides, the

the scoop and will be formed into a stream of a shape indicated by the bottom 28 and the sides 29.

By virtue of the thumb screw 26, the scoop 27 can be placed in selective pivoted positions such that the bottom 28 will be inclined at an angle which will present a desired spray of the water and, of course, by virtue of the thumb screw 22, the spray can be directed to one side or the other with respect to the longitudinal direction of the boat. Therefore, the two adjustments provide adjustment in the longitudinal, as well as the transverse, direction of the boat, and they are hand manipulable adjustments which do not require special tools, so the user can readily make the angular changes while on the water.

Also, the optimum angle of forty-five degrees for the scoop bottom 28 with the water surface "S" can be gaged by the top edge of the plate 23 being aligned with the pieces 18, as shown in solid lines in Fig. 3. V

To, further affect the water entering the. scoop 27,

means such as the shown compression coil spring 32 are provided between the scoop sides 29 to be disposed in the stream of water coming up through the scoop, 27. The means or spring 32 thus intercepts the stream of water and disintegrates it to where a fine spray is created as the stream flows around and through the spring coils. In the shown arrangement, each of the scoop sides 29 has a trunnion or a boss 33 attached to the inside surface thereof to project inwardly and present a mounting. boss which is received by the inside diameter of the spring 32, and thereby the bosses retain the spring 32 in its shown position. The spring would actually vibrate or flexunder the pressure of the water stream, and this would further disintegrate the stream into a desired spray at the outlet side of the scoop 27. Obviously, othermeans could be used in place of the spring 32' such that the means disintegrates the stream of water in the scoop.

While a specific embodiment of this invention has been shown and described, it should be obvious that certain 1.
