United States Patent 2,920,597 iioA'r Mo'oR'iNG APPARATUS Adolph A. Dick, Ciira'l Gables, Fla. Application January 7, 1958, Serial No. 707,547 9 Claims.- (Ci. 111F230 My invention relates to improvements in boat mooring apparatus for securing small boats such as launches and the like to one side of a dock.

, The primary object of my invention generally stated is' toprovide efiicient, simple apparatus for securing such boats to a side of a dock in variably spaced relation thereto as occasion may require, and which may be so fi edvw t large o -l v l 4 To the accomplishment of the foregoing and other objects presently appearing my improved apparatus comprises a pair of laterally spaced mooring arms, means piviotally jmounting the arms at oneend to the dock for vertical swinging and socket andball means on the other ends of the arms and the boat forming universal joints which together with vertical swinging of the arms comnsate for rise and fall of the boat with the tide and for pitching and rocking of the boat, the arms being extensible and contractile to variably space the boat from the dock, the socket means comprising spring closed pairs of jaws automatically opened in response to movement of the ball means into the pairs, releasable locking means for retainingthe pairs of jaws closed, and means for releasing the locking means, all as set forth in detail in the following description, defined in the appended claims, arid illustrated in the accompanying drawings in which:

I Figure 1 is a fragmentary view in plan illustrating a boat secured to a dock by the mooring apparatus of my inventiomn Figure 2 is an enlarged fragmentary view in vertical seetion taken on the line 2--2 of Figure 1;

v Figure 3 is an enlarged fragmentary plan view of one ofthe pairs of jaws, and the locking means therefor and means for, releasing the locking means;

Figure 4 is an enlarged perspective view of the same;

Figure 5 is an enlarged fragmentary view in side elevatidn of the ball means on the boat; and I Figure 6 is an enlarged view in vertical section of a modified embodiment of the invention. Referring to the drawings by numerals the apparatus "of my invention comprises a pair of like mooring arm's each designated generally by the numeral 3 and each 'of which includes a pair of side-by-side flat and rear and train Bars 5, 7, provided with longitudinally spaced openiiigs, a 'at 9, for selective insertion of bolts 11 theretli'r'ough 'to extend or eontract the arm. The arms 3 are tanned of tempered steel.

The 'rnoo'ringarms '3 are pivotally mounted on one side 13 of 'a dock "15 in laterally spaced relation for independent vertical swinging and to extend outwardly from the dock by means of pivot bolts 17 in their rear ends and in pairs of lugs 19 between which said rear ends are interposed and which are secured to the side 13 of the dock 15 by bolts 21.

The socket means comprises a pair of socket forming fixed and

movable fiat jaws

23, 25 of rectangular plate atuthe front end of each arm 3. The fixed jaws 23 extend forwardly flatwise from the front ends of the front bars 7 with reduced tail end lugs 27 bolted, as at 2,920,597 Patented Jan. 12, 1960 to one side of said front bars 7. The movable jaws 25 are hinged at rear ends thereof, as at 31, on top of the fixed jaws 23 for swinging upwardly and downwardly into and from fiat engagement with the fixed jaws 23 to open and close the pairs of

jaws

23, 25 for a purpose presently seen. I

Each pair of

jaws

23, 25 is normally maintained closed by means of an upright compression spring 33 interposed between the fixed jaw 23 and a rearwardly extending right angled lug 35 on the movable jaw. V

The fixed and

movable jaws

23, 25 of each pair are provided adjacent the front ends thereof with a pair of complemental C-

shaped openings

36, 37 mating when the pair is closed and formed by

side walls

34, 38 oppositely beveled, relatively transversely, to form a socket 39 when said jaws '23, 25 are closed. For this purpose the

walls

36, 38 are beveled to incline inwardly to the bottom of the fixed jaw 23 and inwardly to the top of the movable jaw 25.

The fixed and

movable jaws

23, 25 of each pair are formed with rearwardly converging front entrance throats 41, 43 for the

openings

36, 37 for entering ball members on the boat, presently described into the

openings

36, 37. The throats 41, 43 are formed by pairs of

side walls

46, 48 at opposite sides thereof converging to the

openings

36, 37 and which are transversely inclined oppositely on each throat with respect to the other throat to provide cam sides at opposite sides of the throats 41, 43 whereby in response to passing the previously referred ball members through said throats 41, 43 under pressure and when the pairs of

jaws

23, 25 are closed, the movable jaws 25 of the pairs will be cammed and swing upwardly of the fixed jaws 23 to open the pairs of jaws. For this purpose the throats 41, 43 are formed with

elongated side walls

46, 48, which as regards the throat 41, are inclined transversely downwardly and inwardly of the throat 41, whereas, the side walls 48 of the throat 43 are inclined upwardly and inwardly of said throat.

A p'air of ball members 49 is mounted in horizontally spacedrelation on one side 50 of a boat 51 to seat in the sockets 39 by entering the same through the throats 41, 43 and are proportioned to fit in said sockets. The ball members 50 are provided with threaded nut equipped shanks 53 fastened in the side 50 of the boat 51 to extend outwardly thereof and also extend through and are suitably fixed in a fender plate 55 bolted, as at 57, to said side 50 and provided at opposite sides of the pair of ball members 49 with a pair of outwardly extending longitudinal fender bosses 61 for preventing the ball members 49 from catching on wharfs and other objects.

The locking means comprises an upstanding hooked locking dog 63 for locking each pair of fixed and

movable jaws

23, 25 closed,

slots

65, 67 in said

jaws

23, 25 mating when the pair of

jaws

23, 25 is closed and through which the dog 63 depends, a transverse pivot pin 69 pivoting the dog 63 in the slot 67 of the movable jaw 25 for rocking into and from locking position, and a compression spring 71 interposed between said dog 63 and the lug 35 and normally rocking said dog into lockingposition in which a hooked end 73 underlies the fixed jaw 23. A hand grip 75 on the upper end of each dog 63 provides for manually unlocking the pairs of

jaws

23, 25 from a boat for opening. Pull rods 77 pivoted, as at 79, to the dogs 63 and slidably extending rearwardly therefrom through upright guides 81 on the arms 3 provide for manually unlocking the

jaws

23, 25 from the dock 13.

Means is provided for automatically unlocking the

pairsof jaws

23, 25 in response to entering the ball members 49 in the

throats

36, 37 rearwardly under pressure and which comprises the following:

The locking "dog 63 of each pair of

jaws

23, 25 is pro vided above the movable jaw 25 with a pair of laterally extending arms 81 above the movable jaw 25. A pair of push rods 83 extend forwardly from the pair of arms 81 into the throat 43 of the movable jaw 25 to project into said throat at opposite sides thereof into a position such that when a ball member 49 is pressed'rearwardly in the throat the front ends of the rods will be engaged by the ball member and said rods 81 pushed rearwardly to move the locking dog 63 into unlocking position before the ball members 49 starts to cam the pair of

jaws

23, 25 open.

The push rods 83 are operatively connected at their rear ends to the arms 81 of the locking dog 63 by ball and socket joints 85 and are slidable in longitudinal inclined bores 87 in the movable jaw 25, larger in diameter than the rods 83 to compensate for lateral throw of said rods. As will be clear the rods normally project into the throats 43 but are pushed inwardly by the ball members sufiiciently to permit the ball members to pass between their front ends. Bores 89, 91 in the fixed and

movable jaws

23, 25 provide for padlocking said jaws closed if desired.

In actual practice the boat 51 is maneuvered up to the side 13 of the dock 15. Each'mooring arm 3 is swung upwardly by an attendant on the boat 51 or dock 15, one at a time into a position to insert one of the ball members 49 into the throats 41, 43 of the

jaws

23, 25 on the arm. An attendant may then by pulling on the arm and warping the boat force the ball members into and through the throats 41, 43. As the ball member enters the throats 41, 43 the locking dog 63 is automatically unlocked in the manner already described and the movable jaw 25 cammed open by coaction of the ball members 49 with the

cam side walls

46, 48 of the throats 41, 43 so that the ball member 49 may enter the

openings

36, 37 and then the pair of

jaws

23, 25 will be snapped closed by the spring 33 by closing of the movable jaw 25 onto the fixed jaw 23 to form the socket 39.

When it is desired to release the boat 51 the locking dogs 63 are moved into releasing position by means of the hand grip 75 or by an attendant on the dock 13 pull-ing on the pull rod 77. When the locking dogs 63 are thus unlocked pull on the ball members 49 out- *wardly by the boat 51 will cam the pairs of

jaws

23, 25 open. This occurs by camming coaction of the ball members 49 with the

inclined side walls

34, 36 of the

openings

36, 37 and the inner ends of the

side walls

46, 48 of the throats 41, 43. Obviously the pairs of jaws '23, 25 may be unlocked manually instead of automatically if desired by means of the hand grip 75 or pull rod 77 preparatory to entering the ball members 49 in the throats 41, 43.

As will be understood the mooring arms 3 when not in use hang pendant and out of the way and said arms may be extendend or contracted as desired for vertical swinging to compensate for variations in rise and fall of different tides.

In the modified embodiment shown in Figure 6, the ball members 89' are secured on top of a boat gunwale 91 by a threaded nut equipped shank 93 extended through a suitable bracket 95 bolted, as at 97, on said gunwale. Otherwise the construction is the same as in the first described embodiment.

The foregoing is considered as illustrative only of the principles of the invention. Further, since numerous modifications and changes will readily occur to those skilled in the art, it is not desired to limit the invention to the exact construction and operation shown and described, and accordingly, all suitable modifications and equivalents may be resorted to, falling within the scope of-the invention as claimed.
