In the form of the invention illustrated in Figs. 1 to 5, inclusive, the improved boat mooring apparatus includes a dock mounted unit which preferably comprises a metal bracket generally designated by the numeral 10 having upper and lower integral clamp elements 11 and 12, respectively.

Removable clamping elements

13 and 14 are secured to the upper and lower clamping elements 11 and 12, respectively, by bolts 15. In the drawings, the clamping elements are illustrated as being of substantially complementary arcuate shape so as to receive a cylindrical spile, post or metal pipe 16 which is located adjacent a dock 17. These clamping elements may be of any contour required to fit upon a desired support and bracket and may be selectively positioned vertically upon post 16.

The upper clamping element 11 of the bracket 10 is provided with a socket po rtion 18 having a cylindrical bore 19, and the lower clamping'element 12 is provided with a socket portion Zllhaving a splined passage 21 axially aligned with the cylindrical bore 19. The

socket portions

18 and 20 are integrally connected together by a rib 19' which extends vertically between them.

As illustrated in Fig. 1, there is a pair of stationary moor-ing units each comprising abracket 10, arranged along the side of the dock 17 for mooring a boat 22.

Mounted in each bracket'lil is an inverted U-shaped' mooring arm, generally designated by the numeral 23,

formed of resilient spring steel having suitable properties for accommodating return to its original shape and condition following substantially severe deflection. Each mooring arm includes

vertical sections

24 and 25 which are connected and held in laterally spaced relation by a U-shapcd, reversely bent portion 26. The vertical section 25 of each mooring arm 23 is received in the

socket elements

18 and 20 of the respective brackets 10. The lower end portion of the vertical section 25 of each arm is provided with splines 27 which fit into the splined passage 21 of the lower socket element 20. The splines 27 and grooves of the splined passages 21 are uniformly spaced circumferentially about the lower end portion of the vertical sections 25 of the arm 23 so as to accommodate selective positioning of the mooring arms 23 relative to the brackets 10, as illustrated by the dot and dash lines 70 in Fig. 3. The mounted vertical sections 25 of each mooring arm is provided with a collar 28 which has a set screw 29) for securing it in a selected vertical position, such that the splined end of the section 25 is held in a fixed position in the splined passage 21 of its socket element 20. The vertical section 24 of the arm 10 is free to deflect in all horizontal directions in order to cushion any tendency of the boat 22 to move at its moorings. When utilizing the arms 23 to moor a large and heavy boat, defiective movement of the lower free end of the vertical section 24- of the arm 23 may be limited by a chain 30 secured at one end to the lower end portion of the section 24 and at its opposite end to the socket element 20.

Mounted on the side of the hull of the boat 22 is a pair of releaseable coupling units generally designated by the numeral 31. Each coupling unit 31 comprises a base 32 which is fixed by bolts 33 to the side of the hull of the boat 22, as illustrated in Fig. 3. The base 32 of each coupling unit 31 is of channel shape and includes vertically spaced and aligned horizontally extending flanges 34 which are provided with apertures for receiving a vertically disposed pivot element 35. The ends of the pivot element 35 are fixed in the apertures of the flanges 34 by pins 36.

Journalled on the pivot element 35 of each coupling unit is a coupling arm 37 having a forked inner end 38 adjacent the boat and a hooked outer end 39 for coupling with the section 24 of one of the mooring arms 23. The extremities 40 of the branches of the forked end of the coupling arm 37 are provided with apertures for receiving the pivot element 35. Each coupling arm 37 is yieldably held in an extended position substantially normal to the length of the boat 22 by oppositely coiled springs 41 and 42 having their outer end portions seated in apertures formed in the extremities 40 of the branches of the forked end of the coupling arm 37 and having their adjacent end portions seated in apertures formed in the pivot element 35, as illustrated in Fig. 2. A releaseable latch element 43 pivotally mounted at 44 on the coupling arm 37 serves to close the entrance to the hooked end portions 39 of the coupling arm 37. This latch element 43 is yieldably urged toward its locked or closed position by a spring 45 which bears between the latch element and the coupling arm 37 clockwise by movement of the latch element 43 about its pivot 44 to an open position and can be produced by a pull cord 46 which is attached to an car 47 on the latch element 43. The hooked outer end 39 of the arm 37 and the spring pressed latch element 43 together form a snap acting connecting element which can be automatically latched in coupled relationship with the section 34 of one of the mooring arms 23. The cord 46 may also be used as a retaining member to fasten the coupling arm 37 against the action of the springs 41 and 42, along side the hull of the boat 22, as illustrated in dot and dash lines in Fig. 3, when coupling arm 37 is not in use. When the latch is in closed position 48, its outer free end portion bears against the inner side of the hooked end portion 39 of the coupling arm 37 in such a way as to prevent counterclockwise movement of the latch element 43 about its pivot so as to hold the mooring arm 23 against unintended disengagement from the hooked end 39 of the coupling arm 37. Intended disengagement of the mooring arm 23 from the hooked end 39 of the coupling arm may be effected by rotating the latch element 43 to its open position and so maneuvering the boat while the latch element is held in open position as to separate the mooring arm 23 from the coupling arm 43. In mooring the boat 22 along side a dock 17, it is merely necessary to propel the boat forwardly in a course parallel to the dock, while the coupling arms 37 are in their extended positions. When any portion of the outer section 24 of the mooring arm 23 engages the coupling arm, it is guided into engagement with the latch element 43 which is ultimately rotated about its pivot 44 until the outer section 24 of the mooring arm 23 is finally trapped in the hooked end 39 of the coupling element. It is not necessary to simultaneously engage the outer sections 24 of both mooring arms in their respective hooked ends 39 of the coupling arms 37 for after either one of the mooring arms 23 is latched in the book of its proper coupling arm, the boat may be easily maneuvered so as to connect the other mooring arm 23 with its proper coupling arm 37.

In the form of the invention shown in Figs. 6 and 7 the dock mounted mooring unit is generally similar to that shown in Figs. 1 to 5, inclusive, except that the re silient metal U-shaped mooring arm 23 is disposed in an upright position, as shown in Fig. 6 and the free side section 24 of the U-shaped arm extends upwardly beyond its other side section 25'. The bracket 10" of the dock mounted mooring unit shown in Figs. 6 and 7 is also similar to the bracket 10 of the form of the invention shown in Figs. 1 to 5, inclusive. In this form the bracket is secured to a post or spile 16 by clamping elements 11', 12', 13, and 14' with which bolts 15 cooperate. The lower socket element 20' of the bracket 10 is provided with a cylindrical bore 19' in which the side section 25' is received. The upper socket element 18 is provided with a splined passage 21' coaxial with the bore 19' of the lower socket element 20'. Feathered splines 27' are provided on the upper end portion of the side section 25' of the U-shaped mooring arm 23'. The splines 27' and the ways of the splined passage 21' are uniformly arranged so that the outer side section 24 of the mooring arm 23' may be selectively positioned angularly about the axis of its side section 25' by merely lifting the mooring arm 23' in its

socket elements

18 and 20 and tuming it to a desired position and thus allowing the mooring arm to descend so as to engage the splines 27' in the selected Ways of the splined passage 21'. A nut 28' threaded on the end of the side section 25' holds the arm 23' against downward separatory movement from the bracket 10. In this form of the invention, the coupling arm 37 connects with the outer side sections 24 of the mooring arms in exactly the same manner as set forth in the description of Figs. 1 to 5, inclusive. A chain similar to the chain 30 shown in Fig. 2, may be used to limit deflection of the upwardly extending side section 24' of the mooring arm 23', if desired.

In the form of the invention shown in Figs. 8 to 10, inclusive, my improved mooring apparatus includes an elongated steel bar 50 of rectangular cross section, as illustrated in Fig. 10, which is extended horizontally along a clock 51, or other equivalent structure. The bar 50 is preferably secured by bolts 52 to the outer side of posts or spiles 53, which are located along the front side of the dock 51. The bar 50 may be continuous and integral throu hout its entire length or it may be made up of sections arranged in end to end relationship in which case the ends of the adiacent sections may be secured to the same spile or post 53 by respective bolts 52, as illustrated at the left end of Fig. 8. The spiles or posts 53 may be driven into the bed of the body of water adjacent which the dock 51 is located, or they may be mounted directly on the dock.

Spaced pairs of dock mountedrnooring units, generally designated by the numeral 54; are provided. along the dock 51 and rail 50 in an arrangement to accommodate mooring of a' plurality of boats .of different sizes. Each mooring unit 54 include a bracket 55, having a main body portion 56 provided with vertically spaced upper and lower socket elements57 and 58, respectively. The upper socket element 57 has a cylindrical bore 59 and the lower socket element 58 has a splined passage 60. An inverted U-shaped mooring arm 61 is mounted in the socket elements of each bracket 55 and is provided with a splined end 62 which may be selective-1y fitted in the splined passage 60 in the same manner as set forth in the description of Figs. 1 to 5, inclusive. The mooring arm 61 may be held against inward movement relative to the bracket 55 by a collar 63.

The main body portions 56 of the brackets 55 may be releasably clamped to the bar 50 at selected positions by a clamping bar 64, disposed on the side of the bar 50 opposite from each bracket '55, respectively. Bolts 65 firmly, releasably clamp the bar 50 between opposite brackets and clamping bars 55 and 64, respectively. By releasing the bolts 65 and shifting the brackets 55 a ong the bar 59 and then retightening the bolts, the mooring units 54 may be selectively fixed in diverse postions for accommodating mooring of boats of different lengths along a dock.

If desired, the brackets 55 may be constructed as shown in Figs. 6 and 7 and upright mooring arms corresponding to'those shown in Figs. 6 and'7 may be employed in the mooring assembly shown in Figs. 8 to 10, inclusive.

In all forms of the invention the mooring arms are made of resilient steel, such as spring steel, and they are conditioned by suitable treatment to withstand substantial deflection in all horizontal directions without taking a set. The free ends of the arms with which the boat mounted coupling elements connect are free to undergo substantial deflection without taking a permanent set and thus the mooring apparatus cushions all tendency of the boat to move at its mooring. The arms, in all forms of the invention, with which the boat mounted coupling elements connect are of such lengths and so positioned with respect to the maximum and minimum water level or tide level as to register with the coupling elements under all normal conditions of water level. The boat mounted coupling elements are free to shift up and down with the water level at the dock. In all forms of the invention the boat mounted coupling elements can be connected with and disconnected from the dock mounted mooring arms as described in connection with Figs. 1 to 5, inclusive.

While I have illustrated and described several embodiments of my invention, it is to be understood that such is for the purpose of illustration only, and it is contemplated that those skil ed in the art may modify certain details without departing from the spirit or scope of the invention as defined in the claims appended'hereto.
