To all whom t concer/n: i

Beit known that I, DoMrNIoK FRNO- vIoH, a citizen of the United States, residing-at Venice, in the parish of Plaquemines and State of Louisianajl have yinventednew and vuseful Improvements in Dry-Docks,y of

which the following is aspecilication.-

My present invention pertains to drydocks, and it contemplates the provision ot' a dock through the medium-of Vwhich ship workers maybeenabled to work in an upstanding position atall times irrespectiveof the location of therepairs'to be-made tothe ship.

The invention provision of a dockthrough the medium of which the ship to be repaired may be quickly and easily tilted to various positions to assurev the workman obtaining access to the various parts of the hull of a'ship; to position the ship sowas the lightwill be properly thrown on the hull lthereby relieving strain on the workers eyes, and to overcome inrious parts of the ships hull.

The invention further *contemplates the provision of a dock that will enable the Work of repair on a ship being carried on 1n an;

efficient and speedy manner without attending dangerto life and limb ofthe ship-v Figure` 1 is a top plan view of myfnovel dock positioned on its complementarybase or platform.

Figure 2 is a side elevation of the dock shown in Figure l.

Figure 3 is a front elevation of the device with the cradle and ship shown in upright position.

.Figure 4 is a view showing the cradle and ship in tilted position with respect to the dock.

Figure 5 is a View showing the cradle position of the dock in 'extended position.

`Similar numerals of reference designate corresponding parts in all the views ofthe drawings.

My novel dock comprises the base portion composed of the side barskl that are secured to each other by means of the cross-bars 2 to the other ofY the'members Y A fzv ed to enterl the rods rwhereby the Imembers if.: y

4 are longitudinally adjustable with respect vfurther contemplates the Jury to workmen due to inaccessibility of va-f vation,

y My novel cradle .dockA comprises the froiitfzr and rear members 4 that are secured toeach j other bymeansof thetelescoping rodsor.

,The rods 5 are secured to"A one rails n5 -andi 6.,

of the members 4 and therods 6 arey securedV l 4to each other;

eachother after the manner ofthe members f 4` to accommodate the cradle to Avarious lengths of ships.

On the upper ends-of cradle CL Il'provide hooksy 14 to vreceive therods i14a that aref f in turn securedto thev ship A. This provisionis madeinorderto holdthe shijywvith'j respect/to thecradleIC Aduring the tilting operation.`

On thev outer .tace-of themembers provide the windlasses 15 that are provided with thev cables 1,5n that rest beneath the 'cradle C.' By manipulation of the windlass ofthe members 4-fthe cradle will be rocked or tilted with respect to the members or dock 4.

Mountedon the rear extension of the dock ot my device as shown inFigure 2 are windlasses 16 and 22 that -Operatel the cables to extend-and close the dock longitudinally.

tened to .thejear member 4 andy thence oyer Windlass 16. The cables 19 pass over pulleyl 20 fast to the front cnos'sgbarkandnis;secured to hook 21 that is arranged'on one face of member 4 to which the pulley 18 isJ secured.

The cable Q3 is securedfto one member 24- by means of the hook shown and1 passes over the windlass 22' and said ycable, 23 is fast to member't by hook/27 andfpasses from pulley 2161;@ Windlass 22.

Inv ther'practicaluse of v4the invention, the dock members 4 may away froml each other by turning the windlasse's 16 andv 22, to caus'etelescoping of the rods 5 and Gand Y12 and l13. The ship is then run into the cradle and the entire doclrelevated by any means that may suggest itself. The Vship is secured to the hooks ,14 'by the rods 14a and by manipulation ofwindlass 15 the cradle C as well as theship Amay be tilted to Aany 4desired .angle with"respect to the dock and foundation. V

The doclr described lwill permit a Workmanto gain easy accessto the hull of the ship without zfear of injury and the ship and cradle may be tilted atan angle withI a small amount- 'of effort on `the ,pai-t oftheworkfY and rear' portions of the dock longitudinally with respect to each other and onthe: sup,

port and other meanszfor rocking a portion o the dock transverselywithY respect `to the support v 2. Ina dry-dock,y the combination of a support, channels formed longitudinallyin the v`rails of the support, a ship-receiving dockmounted ,on the'support and resting in the channels thereof, members for receiving the ship and hooks and rods for holding the ship tosaid members, telescoping rods sebe positioned near or cured to themembers, a channel infwllh the members travel and ,means .for causing the rods totelescope and bring the members toward..eachY other, otherymeans for causing the members to move away from each other and; anthird means for rocking the members transversely on the ship-receiving means.

3.111 a dry-dock'-,the combination of a base, a frame mounted on the base, channels iormcd in the frame, members having a railv that enters the channel of the frame,`

means for moving the members with respect to the frame and other means secured tothe frame and members or moving each compleinentary frame and ymember with respect to its opposing member.

4:. In a device for the purpose set forth,`

the combination of f a support, a frame mounted on the support,- a rod secured to the frame, a second frame arranged in rear of the'iirst named frame and `having a rod in which the rod of the iirst named frame, telescopes, cables secured to the frames, a windl-ass securedto the support andadaptedv to move the vframes on the support to cause telescoping of the rods or vice versa,i ship receiving cradles having a rail thatlenters acliannel formedin each ofjthe frames and a series of windlasses andlcables secured Lto the frames, 'and adaptedto rock the cradle from', left to right with rsepect to the frames.

5. ln a device for the purpose set forth,A

the combination of upstandingframes, chan-p nels formed ,in the frames telescop-ing rods secured to the frames to permit ofrmovement oi the frames away from o r toward eachother, cradles having a portion that .rel

ceives a ship and provided at theinunder`` sides with a tongue that seats in thewohanfv nels of the frames and means for Vretaining the cradles with respect-to eachother andy comprising telescoping rods, means arranged on the trames for imparting a rockingmovement of lthe cradles with'y respect to lthe,y

frames and other meansior telescoping and extending, the rods.

ln testimony whereof I have hereunto setA my hand in presence of two subscribing witnesses.
