ited ttes Patent 3,028,829 WATER SKI ROPE RETRIEVING APPARATUS Jerome B. Sklenar, 6540 Johnson Ave., Long Beach 5, Calif. Filed May 25, 1959, Ser. No. 815,344

3 Claims. (Cl. 114-235)v tow rope, it must be retrievedbythe operator of the boat. Most generally the rope-is merelyafiixed-at one end to the boat, and the operator must retrieve it by hand and, if necessary, pay itout by-hand when another run is begun with the skier behind the boat. 1 Accordingly, it is an object of the present invention to provide an'apparatus for-use in combination with apower boat for retrieving a-line or rope extending from theboat. v a

It is another object of the present invention to providesuch a retrieving apparatus which utilizes the forward motion of'the boat as a source of power for pulling a line or rope toward the boat.

It is a further object of the present invention to provide such a rope-retrieving apparatus for power boats which can be easily'and quickly moved to or from the retrieving position by the operator of the boat.

Yet another object of the present invention is to pro vide a rope-retrieving apparatus for power boats which quickly and efiiciently retrieves a-rope extending from the boat together with light objects at the end of the rope.

A still further object of the present invention is to provide a rope-retrieving apparatus particularly useful in water skiing for retrievingthe toW rope used by water skiers, which apparatus is simple and economical in con struction and is sufficiently ruggedrto withstand the abusive treatment to which it may be subjected.

The present invention is a rope-retrieving apparatus for use on power driven boats which comprises a reel rotatably mounted at the after end of the boat. The tow rope is aflixed' at one end to the reel. A water driven rotatable member is affixed to the reel and is adapted to be rotated by the force of moving water when the apparatus is moved to the retrieving position with the boat in forward motion such that the water rotates the membet to in turn rotate the reel and wind the rope thereupon.

The novel features which are believed to be characteristic of the present invention both as to its organization and method of operation, together with further objects and advantages thereof, will be better understood from the following description considered in connection with ice tus in the operating or retrieving position with a phantom indication of the apparatus in the nonoperating condition;

FIGURE 4 is a partial view showing an alternative embodiment of the reel used in the apparatus;

7 FIGURE 5 is a view corresponding to FIGURE 4 showing a second alternative embodiment for use with two tow ropes; and

FIGURE 6 is a partially schematic view of an alterna tive embodiment of the present invention.

Referring now to the drawings, there is shown in FIG- URE l a perspective view of an inboard motor boat hav ing the presentlypreferredembodiment of the apparatus attached upon the transom of theboat with the water skier tow rope 10 extending rearwardly from the retrieving apparatus. -The apparatusis shown in FIGURES 1, 2 and 3 in the operating position by which it would be utilized to retrieve the rope 10 when the boat is in forward motion.

As shown in FIGURELthe apparatus is moved from an operating or retrieving position to a non-operating position by means of alever 12 mounted upon the boat at a position which is convenient for the boat operator. By operating the lever 12 from a first to a second position, theapparatus is'moved from an operating to Ca non-operating position, as described hereinafter, through a linkage or cable 14 connected between the operating lever 12 and the apparatus.

Referring now particularly to FIGURES 2 and 3, the presently preferred embodiment of the apparatus includes a base member 15 which is adapted to be mounted upon the transom 16 or after end of the boat. It can be seen that throughout the figures and the description an inboard motor boat is shown and described, and that if an outboard motor boat is used, the base 15 and the position at which the apparatus is mounted upon the boat must be varied and adapted to the position at which the outboard motor is attached to the boat. Similarly, in use with inboard motor boats the base 15 used to mount the apparatus upon the boat must be sooriented that the motor exhausts or other ports through the transom are clear. It willalso be apparent from the following discussion that in some instances the base member can be omitted and the apparatusv can be affixed directly to the boat.

Mounted upon the base member 15 are first and second spaced-

apart brackets

18 and 19 which are affixed to the base member in a stationary manner by fastening the accompanying drawing in which presently preferred embodiments of the invention are illustrated by way of example. It is to be expressly understood, however, that the drawing is for the purpose of illustration and description only and is not intended as a definition of the limits of the invention.

In the drawings:

FIGURE 1 is a view in perspective of an inboard motor boat having the apparatus of the present invention mounted upon the after end thereof and showing a tow rope extending rearwardly from the boat;

FIGURE 2 is a plan view partly in section of the presently preferred embodiment of the present invention to be mounted upon the transom of the boat of FIGURE 1;

FIGURE 3 is a View in elevation partly in section taken along line 3-3 of FIGURE 2 showing the apparameans such as the bolts 20. The

brackets

18 and 19 extend outwardly from the base member 15 and include, in general, an affixing portion 22 and 2.3 respectively and a

bearing arm

26 and 27 respectively. Th atfixing

portions

22 and 23 are of sufficient width to accommodate the fastening bolts 20 and afiix the brackets to the base member at each side of the bearing portion. The altixing portions of the brackets also extend above and below the center line of the bearing arm to provide a firm base for fixing the apparatus to the base member by bolts 20 above and below the center line of the apparatus. The bearing

arms

26 and 27 respectively of the brackets extend outwardly from the affixing portions and base member a substantial distance, as, described more fully hereinafter, and define toward the outward ends thereof aligned

bearings

30 and 31 in which a shaft 32 can be rotatably mounted.

Anti-friction bearings of the type well known to the art are mounted within the bearing arm of the brackets to provide relatively free rotation of the shaft 32 therein.

A reel 34 is formed integral with the shaft or is afiixed thereto, as shown in FIGURES 2 and 3. The reel extends from a position proximate the inside surface 35 of the first bracket bearing arm '26 to a position 1 spaced a substantial distance from the inside surface 36 of the second bracket bearing arm 27. Reel 34 is adapted for Winding the rope 10, one end of which is affixed thereto at 37 as shown in FIGURE 2. A radially extending Washer 38 is positioned between the end of the reel 34 and the inside surface 35 of the bracket 18 in order to provid a low friction contact between the reel and the bracket, and to provide a radially extending flange to retain the rope upon the reel as it is wound.

At the opposite end of reel 34 a substantial space is left between the inner end 39 of the reel and the inside surface 36 of the bracket 19. The space between the inside end 39 and the bracket is sufiicient to accommodate the driving member 40. As shown particularly in FIGURES 2 and 3, the driving member for rotating the reel in response to forward motion of the boat includes a housing 41 formed in two halves which are separable along a transverse separation line. The halves of the housing are connected by means of bosses and connecting bolts 43 to form a closed housing which surrounds the shaft 32 and defines by its interior configuration a circular section 44 symmetrical with respect to the shaft and a tangential section 45 which terminates in an opening 47 through which water is admitted to the interior of the housing. Within the circular section 44 of the housing 41 there are positioned a plurality of radially extending blades 50 which are affixed at their inner end to the shaft 32. In the embodiment shown eight such blades are used and are equally circumferentially spaced about the shaft 32. In order to alfix the inner ends of the blades 50 for rotation therewith a drum 51 having an outside diameter greater than that of the shaft is afiixed to the shaft and the inner ends 52 of the blades are extended into the drum and afiixed thereto for strength in mounting. v p Thusthe shaft 32, thereel 34, the drum 51 and the blades 50 extending radially from the drum are all rotatable as as integral unit. The housing 41, however,

is mounted upon the shaft surrounding the blades in such a a manner that it is pivotal with respect to the shaft 32, and the shaft 32 is freely rotatable with respect to the housing. That is, an opening 53 is provided in the inside surface 54 of the housing, which opening 53 has a diameter substantially equal to but greater than the outside diameter of the shaft 32 to provide a rotatable bearing contact therewith. At the outer surface 55 of the housing 41 an opening substantially equal to but greater than the diameter of the shaft 32 is provided, and an outwardly extending boss 57 is coextensive with the opening 58 as a rotatable bearing surface.

A The distance by which th shaft 32 is spaced outwardly from the base member 15 is a distance sufficient to actoi'nmodate the circuit section of the housing such that it is freely rotatable about the shaft 32. Similarly, the width and diameter of the housing are determined such that the outer ends 42 of the blades 50 and the edges 56 thereof are proximate th interior surface of the circular section of the housing. The various optimum dimensions including the length and width of the blades 50 can be determined by one skilled in the art in view of this description.

Means are provided in combination with an operating member for moving the apparatus from the operative to the inoperative position. In the presently preferred embodiment an outwardly extending arm 70 is affixed to the housing and extends radially outward therefrom. The operating linkage or cable 14 is afiixed to the arm 70 and to the operating lever 12 described hereinbefore such that movement of the operating lever 12 forward will cause the housing to be pivoted counterclockwise in FIGURES l and 3 to the operating or retrieving position. Conversely, a tension spring 60 is mounted between the lever arm 70 and the base to urge the housing in the clockwise direction to a first radial position with respect to the shaft 32 which is the inoperative position shown inphantom in FIGURE 3.

It can be seen that various arrangements can be made for raising and lowering the water inlet 47 from and into the water.

The tangential portion 45 of the housing 41 together with the opening 47 at the end thereof forms a water inlet and path to the coextensive circular section of the housing such that water taken in at the opening 47 is caused to flow through the tangential portion 45 and to impinge upon the radially extending blades 50 to impart a rotational force thereto. An exhaust opening 59 is provided through the housing 41 circumferentially spaced from the tangential inlet such that water flowing into the housing must make a circuit through the housing to the exhaust.

Thus, it can b seen that the apparatus is mounted upon the boat in such a position that the water intake opening 47 will extend below the water line of the boat when it is in the operating position. When the apparatus is in the non-operating position it is pivoted to the position shown in phantom in FIGURE 2 by pushing the operating lever 12 rearward to allow the water opening 47 to raise above the water line.

Accordingly, in operation, in order to retrieve a tow rope 10 which extends outwardly from the boat and the reel 34 of the apparatus, the operator of the boat 12 will pull the operating lever forward, causing the cable 14 to pull upward on the arm 70 until the housing is rotated clockwise a sufiicient distance to place the water inlet opening 47 beneath the water line. Forward motion of the boat will then cause water to flow into the opening 47, through the tangential portion 45 of the housing and into the circular section into contact with the radially extending blades 50 in a tangential direction, such that the blades are forced to rotate clockwise in FIGURE 3. Water forced into the housing will push the blades in its path until exhausted through the opening 59. Rotation of the blades 50 thus causes rotation of the shaft 32 and the reel 34. Rotation of the reel in turn causes the rope 10 to be wound upon the reel between the flange 38 and the inside surface 54 of the housing 41. So long as the boat continues its forward motion, the rope will be wound upon the reel by rotation of the blades 50. After the rope has been fully retrieved the operator will release the operating lever 12 to the rearward position thereof to allow the force of the spring 60 to rotate the apparatus counterclockwise a sufiicient distance to remove the water inlet 47 from the water. The blades 50 and reel 34 are then no longer caused to rotate and the apparatus is inoperative.

An alternative embodiment of the reel of the apparatus is shown in FIGURE 4. This embodiment is so constructed to cause the rope to be wound from side to side upon the reel as the reel is rotated. That is, the surface of the reel is longitudinally concave such that its diameter at the center is substantially less than the diameter at each end. Accordingly, as the reel 74 is rotated to wind the rope thereupon, the slope of the concave surface causes the rope to be moved from side to side to cause a more uniform winding upon the reel.

Referring now to FIGURE 5, a second alternative embodiment is shown which utilizes two reels similar to that shown and described in FIGURE 4. In this embodiment both reels are again afiixed to the shaft 32 for rotation therewith. However, a separating flange 75 is atfixed at the mid-point of the reel and the reel is formed with a double concavity to, in effect, provide two concave reels which operate in unison. Thus, two ropes can be retrieved simultaneously by affixing the end of one rope to the reel at one side of the divider 75, while affixing the end of the second rope to the reel in the opposite side of the divider.

In connection with both FIGURES 4 and 5, the remaining construction of the apparatus and its operation are as described hereinbefore.

Referring now to FIGURE 6, a modified form of the present invention is shown in which the driving member is not contained within a housing and is directly subjected to the force of moving water by placing the radial blades beneath the water line. An indirect drive, such as a belt and pulley arrangement, is'used in this embodiment. That is, as shown in FIGURE 6, a reel i again rotatably mounted between brackets at the after end of the boat but the driving member an is positioned at a distance removed from the shaft 81 of the reel 82.

The driving member 80 again comprises a plurality of radially extending blades which extend from a hub or drum 84 which is rotatably mounted upon a mounting arm 85. The mounting arm is pivoted at its second end 86 upon the bracket 37 which carries the shaft of the reel 82. A pulley 38 is connected to the shaft 89 and a pulley 90 is affixed to the shaft of the driving member 81 A belt 91 is connected between the two pulleys such that rotation of the driving member dd causes rotation of the pulley S3 and the reel 82 to retrieve the rope.

Thus, in this embodiment the driving member is mounted upon the arm 85 for pivotal movement and is placed into the operative or retrieving position by lowering the driving member 8ft beneath the water line, and is moved from the operative position by pulling the driving member 8t) above the water line by means of a cable 92..

Thus, what has been described is a water skiing apparatus which is eificient and economical in construction. The rope retrieving apparatus is particularly useful in retrieving tow lines used in water skiing and can be easily and quickly moved to or from the retrieving position by the operator of a boat.

Although my invention is fully capable of achieving the results and providing the advantages hereinbefore mentioned, it is to be understood that it is merely the presently preferred embodiments thereof, and that I do not mean to be limited to the details of construction above described other than as defined in the appended claims.
