Specification of Letters Patent.

To all whom it may concern:

Be it known that I, SIGMUND senses manager, a subject of the Emperor of Austria-Hungary, residing at Boryslaw, in the Province of Galicia, in the Austro'Hungarian Empire, have invented certain new and useful Improvements in Apparatus for liaising Sunken Ships, of which the following is a specification, reference being had therein to the accompanying drawing.

This invention relates to apparatus for engaging with the decks of sunken ships, whereby the ships may be raised, and if desired conveyed to shallower water.

The apparatus is used in connection with a platform supported over the sunken ship from two other vessels. On the platform a drilling tower is erected ca Jable of move ment to all points of the plat orm and adapted to be fixed. in any position. From the drilling tower which 15 preferably constructed on the well known system of Parker or Raki, tubes are let down through openings in the platform of the sunken ship, and the ships deck or the sides of the hull are drilled accordingto one of the said systems. The employment of the Raki drilling system has the advantage of producing a core which shows the nature of the construction of the ships deck or hull and also shows that the ship has been actually reached.

On the completion or" the drilling operation, a gripper is let down through the tubes. This gripper forms the subject matter of the present invention.

An example of the construction of a gripper according to the present invention is illustrated in the accompanyin drawings, in which:

Figure 1 is a view or the gripperduring its descent. Fig. 2 is a view of the gripper showing its parts in their operative position under the deck of the ship engaged thereby, and Fig. 3 is a plan thereof.

According to this invention the gripper consists of the rod -a having an ernargement against which the gripper is to bear by means disk. -r:.

.e. ...l hearing may be interposed between the disk. Struts --cislr ---cby means of .ihe other ends-of these H7 means of joints -fed by means of joint-pins /tto a disklike head -v'rwhich engages by means of an internal screw'thread with the rod athat is formed at this part with a screw thread '7c. This gripper is passed through the tube Z until its upper edge has moved under the lower edge of the hole previously drilled in the deck of the ship, and in this position its parts are in the positions shown in Fig. 1.

On now rotating the rod --a which is prevented from vertical movement for this purpose the action of the screw thread 7a will cause the head -?I to move down, while the outer ends of the arms -g-- will move against the sides of the tube --Z, and since these ends are formed as cutting edges, or are provided with cutting wheels -0- they will cut through the sides of the tube. As a result oi the continued rotation of the the position shown in Fig. 2, carrying with them a strip -mof the side of the tube.

In order to prevent the gripper from shar ing in the rotation of the rod -'-c-, the low est guide tube may be formed with a corrugated inner surface, so that the largest di ameter will correspond tothe diameter of the upper tubes. The rod acan now be raised together with the gripper by screw ing or the like. The arm g bears against the under surface of the drilled part of the ship and will thus act to raise the ship. In order to utilize the guide tubes L also for carrying the load, therod amay be provided at intervals with grippers of known construction which jam themselves fast against the inside of the tube and thus cause the rod and the tube to constitute a common supporting device. lli desired a number of grippers may be arranged on one and the same red at such distances apart as to enable a number of superposed parts of the deck of the sunken ship to be engaged thereby.

By making the parts of the apparatus of suitable strength, and by providing a sufficiently large number of points o f engage ment with the sunken ship, the latter may be raised from the bottom and then while thus suspended be conveyed a any desired point together with the ve supporting the same which are connected by the platform.

bar a-, the arms will move gradually into through both Having fully described my invention,

, what I claim as new, and desire to secure by Letters Patent, is

In a gripping device for a hoisting i {IP- paratus, the combination with a rod, of

relatlvely movable members mounted thereon, a

plurality of pairs of gripping members, the members of each pair bearing pivotally against said relatively movable members at their outer ends and being pivotally connected at their inner ends by a pin passing members.

2. 'In a gripping device for a hoisting apparatus, the combination with a rod, of relatively movable members mountedthereon', means carried by said rod to cause relative movementbetween' said relatively movable nembers upon rotation of said rod, pivotallv ointed gripping members bearing pivotally' -ed to be moved relatively movable disks on said rod, adapted to move relatively upon rotation of said rod, and jointed rods bearing pivotally against said disks adapted to be moved outwardly without rotating when said disks are moved toward each other.

5. In a hoisting apparatus, the combination with a tube of a gripping device adapted to be lowered therein, comprising a rod, relatively movable disks on said rod, and jointed rods pivoted to said disks, carrying cutting means adapted to cut through said tube, move outwardly and carry sections of said tube therewith, when said disks are mbved toward each other.

(3. In a hoisting apparatus, the combination with a tube of a gripping device adapted to be lowered therein, comprising a rod, relatively movable disks on said rod, adaptrelatively upon rotation of said rod, and jointed rods carrying cutting means bearingpivotally a ainst said disks adapted to cut through said tube, move outwardly and carry sections of said tube therewith, without rotating when said disks are moved toward each other upon rotation of said rod.

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