FERRY-MOORING DEVICE.

Patented sept. is, 1911.

Application led February 1, 1911. Serial No. 605,956.

To all whom 'it may concern.-

Be it known that I, GEORGE W. I-IARNEY, a citizen of the United States, residing at Portsmouth, in the county of Norfolk and State of Virginia, have invented certain new and useful Improvements in Ferry- Mooi-ing Ievices, of which the following is a specification, reference being had therein to the accompanying drawing.

rI`his invention relates to ferry mooring devices, the object in view being to provide simple, effective and reliable mechanism under the control of the pilot in the pilot house or other convenient place on the ferry boat, whereby, upon the ferry boat entering its dock or slip, the mooring mechanism may be thrown into operation at the proper moment to retain and fasten the boat securely in place and in proper relation to the bridge or dock, the entire mechanism being under the immediate control of the pilot.

A further object of the invention is to provide simple and reliable means for releasing the mechanism and moving the same 5 out of the way when not in use.

Vfith the above and other objects in view, the nature of which will more fully appear as the description proceeds, the invention consists in the novel construction, combination and arrangement of parts herein fully illustrated and described.

In the accompanying drawings, Figure 1 is a diagrammatic plan view of a suiiicient portion of a ferry boat and dock and bridge to show the application of the present in vention. Fig. 2 is a vertical cross section through the same on the line 2 2 of Fig. 1. Fig. 3 is a side elevation of one end of the boat illustrating by full and dotted lines some of the operating connections.

Similar reference characters are employed to designate corresponding parts throughout the views.

Referring to the drawing, 1 designates a ferry boat which has a pilot house 2 from which the mooring mechanism is controlled, the ferry boat being shown moored in its slip that includes the fender racks 3 at opposite sides of the slip and the usual bridge 1 that is shaped to correspond to the end of the ferry boat. It will be noted that the fender racks are spaced from the bridge l so as to provide recesses or openings 3a into which the mooring devices are adapted to enter and engage the ends of the fender racks to lock the ferry boat in its moored position, as clearly shown in Fig. 1.

Mounted on the ferry boat 1 at opposite sides of the bow are mooring devices in the form of hooks 5 that are projectable outwardly in a lateral direction to enter the recesses 3a and engage the ends of the fender racks 3, said hooks being fulcrumed in suitable bearing brackets on the deck or other suitable part of the ferry boat. rIhese hooks are normally retracted and are adapted to be thrown to locking position by any suitable mechanism that is under the control of the pilot of the boat from the pilot house 2.

In the present instance, the hook-operating mechanism includes an endless cable 8 that is connected with arms 7 with which the hooks 5 are provided. The cable 8 runs around suitable guide pulleys 9, 10 and 11 and between the pulleys 11, a take-up weight 12 is attached to the cables preferably by means of a pulley block 13 which will insure the easy operation of the device, said weight serving, by drawing on the cables, to swing the lever arms 7 and the hooks 5 from the full line position of Fig. 1 to the dotted line or retracted position shown in the same figure.

The double cable is provided with a rearwardly-extending bight or loopvll which passes around a pulley 15 on the forward end of a piston rod 16 which extends longitudinally of the boat and is provided with a piston 17 working in a steam cylinder 18 to which steam is admitted through a steam supply pipe 19 for the purpose of forcing the piston 17 rearward and drawing on the cables in a direction which will cause the hooks to be projected into engagement with the fender racks. The steam supply pipe 19, which may be fed from the boiler or other suitable supply, is provided adjacent to the cylinder 18 with a three-'way valve 20 controlled by a rod 21 which extends upward into the pilot house 2,l where it is provided with an operating lever 22. Although the mooring hooks are shown as operated by a single motor, it is obvious that the hooks can be independently operated by each hav ing its own mechanism controlled from the pilotI house.

As soon as the vessel enters the dock and is in proper relation to the bridge thereof, the pilot by means of the lever 22 allows steam to enter the cylinder 18, thereby drawing backward the pulley 15 and throwing the hooks 5 outward into engagement with,

rions heights. The mechanism as a whole is also under the direction and immediate control of the man in the pilot house.

F rom the foregoing description, taken in connection with the accompanying drawing,

the advantages of the construction and of themethod of operation will be readily apparent to those skilled in the artto which the invention appertains, and while I have described the principle of operation of the invention, together with the device which I now consider to be the best embodiment thereof, I desire to have it understood that t-he device shown is merely illustrative, and that such changes may be made when desired as are within the scope of the claims appended hereto.

Having thus described the invention, what I claim asnew, is

1. A boat provided with normally retracted mooring devices movably mounted to be projected laterally from the sides of the boat, yielding means for normally holding the devices retracted and operating to return the 4devices from projected to retracted position,

and a motor operatively related to the devices and capable of acting in opposition to the said means for proj ect-ing the devices to mooring position. p 2. A ferry boat provided with mooring hooks, a motor mechanism connected with the hooks for throwing the same outwardly to mooring position, a pilots controller for the motor, and means cooperating with the motor mechanism to retract the mooring hooks.

3. A ferry boat provided with a mooring hook mounted to swing outwardly and rearwardly to mooring position, a mechanism I, for operating the hook including a motor for moving the hook to mooring position, and means connected with the hook for retracting the same when the motor is released.

4. A ferry boat provided with a mooring hook, a motor operatively connected with the hook for throwing the same to mooring position, and separate means for retracting the hook when the motor ceases operating.

5. A ferry boat provided with a mooring hook, a cable connected therewith, and coaetiiig motor devices bot-li connected with the cable for projecting and retracting the hook.

6. A ferry boat provided with a mooring device adapted to be projected laterally from the boat to mooring position, a motor for moving the hook to mooring position, and a weight connected with the hook for retracting the same .when the motor ceases operating.

7. A ferry boat provided with a mooring hook projectable laterally therefrom, a cable connected with the hook, a weight attached to the cable for yieldingly holding the hook retracted, and a motor connected with the cable for projecting the hook against the pull of the said weight.

S. Aferry boat provided with laterallyprojectable mooring hooks,a cable connected with both hooks, means for guiding the cable, a weight attached to the cable and acting on both hooks to hold the same retracted, and a controllable motor operative through the cable to project the hooks to mooring position against the pull of the said weight.

9. A ferry boat provided with mooring devices adapted to engage a` ferry slip, an endless cable connected with the devices, means attached to the cable and normally operated on the devices to hold the same in inoperative position, and a controllable motor operating through the cable to throw the devices to and hold them in operative position against the effect of the means.

l0. The combination o-f a ferry boat, mooring devices disposed at opposite sides thereof, an endless cable extending transversely to the ferry boat and connected with the devices, and alternately acting means connected with the cable for throwing the devices to and from operative position.

ll. The combination of a fei'ry boat, mooring devices disposed at opposite sides thereof, an endless cable extending transversely to the ferry boat and connected with the devices, means connected to the cable for yieldingly holding the devices in retracted positio-n, and a controllable motor connected with another portion of the cable for moving the devices to operative projected position against the eifect of the said means.

In testimony whereof I aiiix my signature in presence of two witnesses.

GEORGE WALTER HARNEY.
