JOHN T. COWLES,OF CHICAGO, ILLINOIS;

SHIP-RAISING MECHANISM.

Specification of Letters Patent.

- Patented Dec. 2, 1919.

Application filed February 17, 1919. Serial No. 277,534. i

adapted to be operable from the surface of water in which a ship is sunk for raising such ship.

Other objects will appear hereinafter. An embodiment of my invention is illustrated in the accompanying drawing, form ing a ipart of this speclfication, and in which Figure 1 is a vertical section takenthrough a device embodying my invention. Fig. 2 is a side elevation of my device showing derlying parts; and

ig. 3 is an enlarged section taken on line 3-3 of Fig. 1.

Referring more particularly to the draw- 7 ing, I have indicated an elongatedharpoon or piercing member; which may be formed of a single integral part or made up, as indicatechof a number of parts. In the form shown a body member-5 has a hardened point 6 secured thereto at its bottom'end and a shank 7 secured to its upper end by means ofa-sleeve 8 and rivets 9. By making the piercing member up of a numberof parts, as indicated, the point can be made of harder. material thanis necessary for theremainder of the piercing member. :Also, making the shank separate and securing it to the body portion 5 enables the shank to be renewed without renewing the body portion, and also makes the shank more cheaply manufactured than if it were made integral with the body 5.

At the top of theshank 7 I provide an opening 10 through which a cable 11, or its equivalent, passes. The cable 11 serves to suspend and lift the piercing member. A pulley '12. may be provided in the opening 10 to reducefriction on-the cable 11.

The body portion 5 of the piercing member is preferably provided with grooves 13 in which are pivoted prongs 14, asat 15. Each of'the prongs 14 is provided with .2.

portions cut away to disclose un-v locked on the shank 7,

also permits the useot' point 16 whichengages a shoulder 17 on the body 5 at the'inner side of one of said 7 grooves 13. In the bottom of each'groove is a sprlng member '18 which is adapted to swing the prong 14 laterally from the slot when such prong has-beenreleased. The prongs '14 are normally held in the grooves 13 by a ring 19 which is slidably mounted on the body 5. I

A sliding member 20 is provided with an slidable over the shank 7 of the piercing member.

The member 20 is provided with looking members 21 which are adapted to engage recesses or roughened places 22 on opening and mounted on the cable 11 and" theshank 7. Any form of lockingmeans 21 may be provided, the form shown s1l1ent springs whioh'are adapted into the notches 22 as the member over such notches.

At-one side of the member 20ris alug 23 having a chain or cable 24: connected there being re- 20. passes to. The chain 24 is connected to a pontoon I .25. The arrangement is such that the chain 2 1 is connected near one edge of the'pontoon 25 so that when the member2O is the pontoon 25 will lie substantially shank .7 and cable 11. This arrangement a number of ponto spring vertically close to the toons 25 and locking members 20. on the shank 7 wvlien. such a thing is desirable. The lug 23 1s also provided wlth a lvertically extending opening 26, and infthis,

opening is a hook 27. The hook hasa cable 28 connected thereto and through a slot 29 in thebodyr5 and from thence upwardly tothe top of thewater in which the device s immersed. In the slot 29 I preferably provide a duce friction onthecable 28 as through the body 5. The device, is operable without the pulley 30..v Thehook 27 is provided with an eye 31,

it passes that an upward movementof the cable 32 In operation, the cable 11Yis attached to an operating device, not shown, and the cable l1 allowed to pass over the pulley 12 to lower the piercing member into. the water said cable passes T pulley 30 to rehowever,

and a-cable32 is connected to the eye 31 so will draw thehook 27 out of the opening26.

in which. a boat, or the like, isto be raised.

When the device is being loweredthe prongs 1 1 are disposed in the slots 13 and held the piercing member has been'lowered un- .iio thereineby the ring 19, see Fig. 2. When I of such boat, the ring 19 is moved on the body 5 which releases the prongs 1%. The latter is moved to the position shown in Fig. 1 by the springs 18 and gravity. When the piercing member is brought into engagement with the boat side 35 substantiall as indicated in Fig. 1, the weighted member 83 is raised by means of the cables 3-4; up to the top of the water and taken off or cable 11.

Before the piercing member has been lowered into the water at all the cable 28 must be threaded through the opening 29 and the book 27 held at the top of the water. Then after the piercing member is aflixed to the boat side, the member 20 is placed around the. cable 11 and the hook 27 engaged in the opening 26. The cable 28 is then tightened drawing the member 20 and pontoon 25, which is connected to tl e member 20 by the chain 2%.

snap into the notches 22 as the member 20 passes over them, and when the member 20 is brought down as low as it is desired on the shank 7, the locking springs 21 engage the notches 22 and prevent upward move ment of the pontoon and member 20. The cable 32 is then tightened which raises the hook 27 out of the opening 26, and upon loosening the cable 28 sufficiently, the cable 32 will bring the hook 27 back up to the top of the water where it can be engaged in another similar member 20 to pull down another pontoon 25. It will thus be seen that asmany pontoons may be brought down and secured to the shank as there are sets of notches 22 in the shank. The pontoon 25 is preferably formed conical at its top and bottom ends so that there is no danger of one pontoon locking against another.

When the desired pontoons have been secured to the shank 7, the cable 28 is loosened and by means of the cable 32 pulled through the opening 29-and brought up to the top of the waterwhere it can be attached to another piercing member, not shown similar to the one shown. The cable 11 may also be removed from the-shank 7 by loosening one end and drawing it by the other end. It will therefore be seen that the piercin her is secured to the boat side and i ber of pontoons afiixed on the shank of piercing member and all of the cables used down over the cable 11 and. onto the sham; '7. -The spring members 21' pivoted insaid recess and adapted to swing out of the latter; a member slidably mounted on the piercing member; a cable'attached to sand slidable member and passmg laterally through the piercing member adjacent said prong for moving the slidable member toward said prong; means for detaching the 7 cable from the slidable member; and means for holding said slidable member against movement away from said prong.
