JOHN CHARLES. SNELLING, or WANDSWORTH, ENGLAND.

sTowING, LOADING, AND LAUNGHING or. BOATS neon: SHIPS.

Application filed June 12, 1913 Serial No. 773,268.

To all whom it may concern Be it known that 1, JOHN CHARLES SNEL- LING, a subject of His Majesty the King of England, residing at VVandsworth, in the county of Surrey, Kingdom of England, have invented certain new and useful Improvements in or Relating to the Stowing, Loading, and Launching of Boats from Ships, of which the following is a specification.

This invention relates to improvements in the stowing, loading and launching of boats from ships or vessels at sea.

One objectof the invention is to provide improved means for launching the boats from'either side of the ship at will, so that they will reach the water at a safe distance from the side of the ship.

' Another object is to provide an arrangement whereby more boats may be stored in such a manner that they will require fewer men to attend to them while being launched.

Further by my invention a more effective control is obtainable over the launching of the said boats; and in addition allthe boats are available for launching irrespective of the'inclination of the ship.

[Referring to the accompanying drawings which show one method of carrying this invention into practice, Figure 1 is a longitudinal elevation of a sliip,,partly in section; Fig. 2 is a plan view thereof, showing two boats in position and two removed. Fig. 3 shows the lower end of the derrick drawn to an enlarged scale and partly in section with a threaded double drum reeiving a pair of ropes. Fig. 4 is a pro posed plan view, of a control station with the crane removed. Fig. 5 shows an enlarged view of the yoke piece, and Fig. 6 shows a means of strengthening or guying the crane against wind and other pressures, or rolling.

In carrying out my invention the required number of boats a may be stored in any part of the ship within range of the launching gear but preferably in a well or wells 6 in the upper decks of the shipthus giving a clear View from the side thereof and the well is shown as so arranged that the boats when stored therein extend crosswise of the ship. They are stored alongside and above one another and as shown rest on swivel or removable racks or beams 0 across the well 11 in the, deck. These racks arev pref- Specification of Letters Patent.

erably mounted upon a column or columns d and are capable of being swung around clear of the path of the lower boats as shown in Fig. 2 so that these can be filled with pas sengers and launched in turn; thus, by enabling all. to get readily seated, much confusion is avoided.

The boats are raised and lowered intur by a derrick e, the arm ofwhich is preferably of tubular construction and, as shown in Fig. 3, could be mounted upon a table 1 operated by a suitable motor 2, (Fig. 4). While only one derrick would generally be employed in launching the boats successively, more may be provided if desired. The derrick or derricks are placed midway of the width of the ship so as to swing to either side thereof, thus bringing the life boats lengthwise-of the ship because in the stored position they extend crosswise of the ship.

The derricks 6 would be mounted on the highest part of the deck adjacent to the funnels or masts f and each derrick,where more thanone is employed would then form a separate launching gear although operated by the same engine or dynamo 9. Means may be provided for manually operating the gear in case ofan accident, or the standby engine It could'be used.

By the use of derricks instead of the usual launching gear larger boats ranging from forty to sixty feet can be used with convenience The boats are preferably provided with detachable wheels at at each end working in vertical grooves a to prevent end movement in storage and serve as guides when launching. The operating gear for the derrick 6 consists of a wire rope 7' preferably attached to the funnel or mast f in the manner shown in Fig.1; its lower end passing into the control box on a high part of the deck where it is attached to a drum 7a which is controlled by a suitable motor Z. The gear for'one or more derricks may be controlled from the control boX by one or more'of the competent members of the crew who is thus out of reach of all possible excitement and therefore in a position to handle the boats in themost expeditious manner. The raising'and lowering gear for the boats consists of a pair of ropes m, 11, preferably passing through the tubular derrick arm and operated by an internal combustion engine or motor 0 placed in a raised position so as to be entirely independent of the other machinery and capable of running until the last possible moment.

The derricks are provided with crossheads or arms 79 g at their tops' for worl ci 'n g the pair of lines or ropes m 92. These lines or ropes are connected at their ends to a yoke piece 1" and in the control box j they are wound on to a common drum or on to av pair of drums 8 divided in their center and preferably provided with opposed threads to insure that they are simultane ously wound thus the yoke piece is kept horizontal during operation. The yoke pieces 1" are provided with sliding bolts or hooks t preferably controlled by a rack it formed on the bolt, and acting in conjunction. with a. quadrant v on a common operative lever w so that the boats which are held thereby near each end may be released from. both ends. at once.

If desired, electrical apparatus. can be at tached. to the ends. of. the bolts, so that. a.

signal. light could be operated automatically in the control station onthe release ofa boat from the yoke piece.

Affixed to the. head of the derricks and operated. by dynamos connected to the launching engines are powerful lights pro-- vided in such a way that they illuminate the operationswhen used at night. By the removal of the yoke pieces the derricksmay be. used for other operations such as loading the ship, thereby insuring their maintenance in working order.

hen not in use the derricks may stand vertical with the funnel or mast, or in a lowered position as shown in Fig. 1. In each case they are preferably provided with crutches m for extra support and the yoke piece with chains attached rest on a rack or may be attached to an emergency boat, which can, by the above described method, be launched while. the vessel is still under way with the crew aboard the small boat. It will therefore be understood that the boats could be launched fordrilling purposes whileat sea.

To provide for the extra strain of the derricks 0n the funnels the stays of same. are strengthened so that some can be removed to allow sufficient room for the swing of the boats. Extra support for the derrick is also derived from an. endless guy rope y attached to the upper part of the derrick and passing under the deck from side to side of the ship as shown at z in Fig. 6.

It is intended that all the boats should be of the high powered motor type; should this not be so'it would be advantageous thatthe first to be launched should be high powered boats so that when the other boats are launched they could takethem in tow. This arrangement has in view the. efficient man.-

6 agement of the greater number of lifeboats which would require more seamen than are now carried. Therefore as this invention provides that many I'nore lifeboats can be carried than formerly by the employment of the motor boats, fewer men are required in the lifeboats thus making the invention a complete method or system of saving life at sea.

What I claim as my invention and desire to secure by Letters Patent of the United States is l. A. ship provided with. a well for the storage of life. boats, said well having superposedv racks therein for the; support of life boats and each rack being constructed forv movementout of the-path of a life boat supported on the next lower rack or racks, and. means for. lifting the life boats from the well.

2. A ship provided with a well for the storage of. life. boats, said well having superposed racks therein for the support of life boats and eachrack; being constructed for movement outlof the. path. of a life boat supported on the next: lower rack or racks, and means. for. lifting the; lifeboats from the well, said means. comprising a derrick mounted on the. ship adjacent to the well and having! boat engaging, lifting and releasing. devices, andso' related to the width ofthe. shipas to. move the. boats from the well and lower them from either side of the ship.

3'. A ship provided withv a boat well having superposed racks-each. adapted for the support of a life boatand each rack being mounted for movement out of the path of life boats supported upon lower racks in the well.

4. A ship provided witha storage well in the upper deck, said well having columns therein. with racks thereon each mounted to be swung out of the path of boatssupported by lower racks on the same columns.
