MooRING DnvIcE.

Application filed February 26, 1925. Serial No. 11,684.

This invention relates to devices for mooring boats to bridges such as that illustrated in Reissue Patent No. 14,313, to Du Bosque, granted June 5, 1917.

The invention relates more particularly to the connection or hitch between the lifting and counterbalancing mechanism and the bridge and boat.

The invention has for its salient object to provide a practical and simplified connection or hitch between the lifting or counter'- weighting mechanism and the boat. and bridge whereby the bridge and boat will be securely connected together'.

Another object of the invention is to provide a hitch that can be readily attached to and detached from the bridge and boat.

Further objects of the' invention will appear from the following specification taken in connection with the drawings, which form' a part of this application, and in which- Fig. 1 is an elevational view somewhat diagrammatic showing the lifting and counterbalancing mechanismand the connection between the bridge and boat.

Fig. 2 is a side elevational view of the connection or hitchv shown in Fig. 1.

Fig. 3 is a view similar to Fig. 2 but illustrating a slightly modified form of the invention.

Fig. 4 is a view similar to Figs. 2 and 3, but illustrates another form of the invention.

Fig. 5 is a sectional elevation on an enlarged scale illustrating the swivel connection between the hitch and the bridge, and

Fig. 6 is a viewv similar to Fig. 2, but illustrates a further form of the invention.

The invention briefly described consists of the combination of a boat, and a bridge preferably hinged and over which passengers and freight can pass to and from the boat, and lifting mechanism so connected to the bridge and to the boat that the bridge and boat will be firmly anchored together. The hitch or connection between the lifting mechanism and the boat is so constructed that the lifting force is divided into horizontal and vertical components whereby the boat and bridge will be drawn together' and whereby the interengagng parte' at the bridge and boat will be vertically supported. Further details of the invention will appear from the following description.

In the embodiment of the invention illustrated in Figs. 1 and 2, one end V10. of a bridge is shown, the bridge preferably being hinged in the usual manner. Stationary parts of the dock are shown at 11 and cross beams 12 extend between upright portions 13 of the dock. The greater portion of the weight of thebridge is balanced by counter-` weights 14 which are connected to the outer or free end of the bridge by chains or cables 15 which in turn pass over sheaves 16 mounted on the beams 12. The counterweights 14 exert a lifting force of constant magnitude on the bridge.

In order to exert the necessary lifting effect on the bridge and boat to securely anchor these parts together, an auxiliary weight 2O is supported on cables 21. A yole 22 is Vsecured to the cables 21 and supports a plurality of sheaves 23 and the weight 20 is also connected to a frame 24 having a plurality of sheaves 25 secured therein. The sheaves 23 and 25 correspond 1n number and a cable 30 is secured at one endI 31 to the yoke 22 and passes around the sheaves 25 and 23,t'he opposite end ofthe cable being connected to a drum 2G which is shown as driven by a motor 27. A platform 28 supported by springs 29 is disposed beneath the weight 2O and ,is adapted' to support the weight when the cable 30 is suiiiciently slack to permit the weight to rest thereon.

Each of the cables 21 passes over sheaves andv has its free end connected to a link 36.

In the embodiment of the invention particularly illustrated in Figs. 1, 2 and 5, the free end 37' of the bridge has swiveled therein an anchor bolt 38, the bolt being mounted in bearings 39. rlhe bolt 38 has lugs 40 eX- .tending upwardly therefrom and a lever 41 is pivoted to the lugs 40. An eye 42 is also pivotally connected to the lugs and is connected by a chain 43 to a link comprising a pair of sections 44 and 45 adjustably connected by a turnbuckle 46aA llhe upper end of the section of the link is connected 47 the linie 345i The lever 41 is connected intermediate its ends at to a chain 51 which in turn is connected to a hook 52 carried by the boat 53.

The end of the boat adjacent the bridge may be undercut as shown at 54 to receive an overhanging portion 55 of the bridge. The free end of the leveil 4l is connected by a link 5G to the link 3G.

In operation, the cable 30 is slacked to a sufficient extent to allow the oif'erhanging portion 55 of the bridge to seat in 'the undercut portion 54 of the boat. rllhe chain 5l 1s then passed over the hook and the cable 30 is tightened thereby lifting weight 20 and tightening the cabl s 21. s the cables 21 are drawn taut, the lever 41 will exert a lifting and drawing force on the boat, thereby drawing the boat into engagement wit-h the end of the bridge and securely locking` the boat and bridge together. In other words, the force exerted on the cable 2l will be divided into vertical and horizontal components.

In the embodiment of the invention illustrated in Fig. 3, the hitch illustrated is designed on the same principle as that shown in Fig. 2. In this form of the invention, however, the lever 4l is connected by a link to the hook 52 and the swivel bolt 48 is connected by a link 6l to a link G2. A turnbuckle 63 adjustably connects one end of the link 62 to the pivotal connection 64 of the link 6l.

In the embodiment of the invention shown in Fig. 4, the cable 2l is connected at 70 to the free end of the lever 4l and there is no direct connection between the cable and the bridge. In this case, the bridge is raised and lowered through the intervention of the connection of lever 4l to the swivel bolt 38 carried by the bridge and after the bridge rests on the end of the boat, the cable is slacked to permit the link 60 to be secured over the hook 52.

In Fig. 6, a simpler form of the invention is shown in which the cable 2l has secured to its free end an eye which in turn is connected to an eye 76 on the bridge by a cable or chain 77 and to the hook 52 on the boat by a cable or chain 78. In this form of the invention, the vertical lifting force on the cable 2l is divided into vertical and horizontal components tending to vertically support the bridge and boat and to draw these parts into firm engagement with each other.

From the foregoing description it will be seen that simple and practical means has been provided for firmly and securely anchoring or mooring a boat such as a ferry boat to a bridge.

Although certain specific embodiments of the invention have been particularly shown and described, it will be understood that the invention is capable of modification and that changes in the construction and in the arrangement of the various cooperating parts may be made without departing from the spirit or scope of the invention, as expressed in the following claims.
