To all whom it mag/concern.

Be 1t known that LFERNANDO Srann Y XIMIENEZ, a citizen of the United States, re- 1 siding at New York, in the county of New York and State of NewYork, have invented new and useful Improvements in Floating following is a specification. V This invention relates to floating drydocks and j has for its primaryobject'the construction of a dock of the character set forthwhich shall be comparatively inexpensive to build, eflicientof operation and particularly adaptedto the uses of such structures,

A further object of this invention is to provide a dock ofthe character set forth with means. whereby the submerging and raising thereofmay be'accomplished inthe most effective manner, preventing any side motion when submerging and securing at all times a stability. for the dock and the vessel carried thereby.

A still further object of thisinvention is to construct a floating dry dock. which can be readily transported to any desired location. I a I Another ob ect: of the construction described herein is -the provisionof a floating dry-dock with means for controlling the raising and submerging movementsthereof in such a manner as to permitj o'f Y control from specified points of thedock to enable the employment" of a minimum amount of seen, is of such a size as to accommodate afujlly equipped machine shop, as well as operation to control themovement of the [clock I a 1 V "With the foregoing and other objects in f "view, as will from time to time appear hereinafter this invention consists in }the peculiar arrangement and combination ofthe various cooperating elements of' a floating drydockas described inithe following specifi'cation and more particularly. pointed out in the appended claims.

i Specificati on of Letters Patent. Patented Ma y, 9

Fig. 4 is a longitudinal section through one of the pontoons and,

Fig. 5 is asectio'n through one of the pontoon draining valves. I

6 designates va hollow pontoon preferably cylindrical and tapered at 7'7. The base of they dry dock is formed by a plurality of longitudinally extending strips 8; spaced apart and connected by transverse strips 9 which support vertical members '10 carrymg a second set of transverse str lps 11 adapted to connect a secondseries of longitudinally extending strips 12, thus forming a plurality of rectangular skeleton frames each one of which is adapted to incase and support a plurality of the pontoons 6 placed end to end in parallel series across the enor open spaces between the tapered ends and also beverse frameworkstrips which carry the spontoons. v

At either side of the base are skeleton towers 13 extending up from bases 14 carried by the base frameworlgjthe towers 13 supporting a' machinerydeck 15 whichis reached from themaindeck 16 by astair-' way 17. This machinery deck, as will be the air compressors and pressure tanks for framework-thus relieving the pressure against the dock bottomduring thesubmerging movement. ,7 t Each of the pontoons 6 comprises'a cencompressed air for. use in operatingthe dock as will be hereinafter described. i

75 tween; the various longitudinal and transral cylindrical portion 21 to Which are riveted at 22-22 conical me1nbers23 capped by members 2 llrivetcd thereto at Near the center'of the cylindrical portion 21 a pipe 26 depends through the top thereof and extends nearly to the bottomof" the pontoon. The ipe 26 carries: on its 1 outer end a check valve 27 with which is connected one end of a pipe 28 which extends upwardly through a 'casing'29 within to which is attached one end of a pipe 3% extending through the casing 29 to the control house 80, where it is provided with a blow off val e and a pressure gage 36. Adjacent to the pipe 2G.the pontoon cylindrical section isequipped with an upper air-admitting and lower watendischarging valve device, illustrated lllClGliitll 1nF1g. 5. This dev1ce comprises a short cylinder 37 extending inside the pontoon at an opening 38 therein, which is provided with a flange 39 riveted to the pontoonshell, the rivets also passing through the flange of a collar l0 in order to fasten it to the outer surface of the pontoon shell about the opening 38 and on this collar is bolted by means of bolts i a cap 42 provided with central threaded nipple d3. At suitable intervals about the cylinder 37 near its upper end'are provided relatively large ports e l, the interior of the cylinder37 being provided witha bushing containing a circumferential series of rel: c atively small ports 45 adapted to aline with the ports 4:4. and uniformly spaced apart. A piston i6 is adapted to work within the eviinder 37 and is pro'vided with a stem 47 which extends nearly to the bottom of the cylindrical portion of the pontoon and alincs with a water outlet opening 48 formed in the pontoon shell. On the piston rod 4711821]:

its lower end there isprovided asleeve i9 confining between it and a collar 50 a spiral spring 51 adapted to'normally hold the pisto'n rod l'Tand the piston to in raised posi-- tion above the ports l i, 1:5, the sleeve be- 50 ing provided. with depending cage-forining 52"connec'ted at their lower ends by means of a ring 53 bolted to the inner surface of the pontoonishell about the opening 48 these bolts passing through a mug 55 upon the outside of the pontoon shell, the

said ring being provided with an annular valve seat 55. From the ring extend legs 68 forming a bowl-shaped member 690011- taining a central base opening 70 provided 7 60 with a guide thimb-le 71.

A continuation 7 2 of the piston rod 4L7 is provided with ahead 73which is coi'ifined in a recess formed in the bottom of the rod 47 by a flanged sleeve 73 bolted thereto at c5 74. 'This n1e1nber72 terminatesat its lower any suitable source."

end in avalve head 75 adapted to normally close upwardly against the seatao and provided with a depending cylindrical skirt 76 having radially disposed ports 77' and an extension 78- guidingly engaged within the thimlole 70. f. V

Fromthe nipple L3 extends a vpipe-TE) which-passes upwardly through the casing '29 to the control house 30, where said pipe is provided with a cut-off valve 80 connecting'it with a connpressedair supply pipe 83., which is supplied with compressed air from Adjacent the vent the pontoon is pro vided with a valve device represented as a whole by the numeral 82 andbeing in every detail of construction similar to the one from which the pipe 'Tllextends with the single exception that the cylinder 34 thereoi is not provided with any ports 4%, do, so that no furth r description of this valve mechanism is necessary, it forming a water inlet and pressure equalizing valve as hereinafter explained. From thevalve S2 tends a pipe 83 which extends upwardly through the casing 29 to the control house 30, where it is provided with a out ell valve Set which connects it with a compre sed' air supplying pipe line Sfisupplied by: any-suitable source of compressed air. V

The construction as abovedescribed is the same for each pontoom each control house receiving the. piping from a certain set of pontoons, as diagraininatically' indicated in Fig. 3, the pipe lines 81. and 85 being provided. with. cut-oil valves 86 and "87 respectivelv, in order to cntirelycut off the supply of compressed air to the plurality of valves 80 211M184, v The'operation of the construction above described is as follows When it is desired to submerge the base deck, of a dock in orderto receive the vessel, the operators in the control houses 30 open the valves 84" which. permits air from the compressed air supply pipe 85 to'flow into the various pipes 83 to the respective valves 82, whereupon action of the compressed air upon the piston 46 will cause the valve 75 to be forced from its seat 55 against-the pressure of the wat s. and permit water to flow upwardly and into the pontoon, through the opening 48, the pipes 26 with their correspondmg gages 32--serv1ngto amdlcatc 1n the control houses the pressure of the water i within the pontoon. Whcn'the dock has been submerged to the desired. level each valve 84: will be closed toprevent any further flow of compressed air, thuspermitting the valve- 82 to close under the pressure of the water, and the action of their springs 51, thus reseatingeaoh valve 7 5 against its seat 55 and preventing any further entrance Of the water. V

The dock is now in position toreceive a vessel. I When is desired to raise the shown in detail in Fig' 5 and cause the piston to move downwardly within the casing 45, which permits the compressed airto flow into thepontoon through the apertures 45 and 44, and at the same time unseats the valve '7 5 from its seat 55, as in the action described for the other. valve 82. The pressure of the compressed air which is flowing into the pontoon through the openings 45 and 44 will cause the water therein to be forced downwardly and outwardly through the opening 48, the pressure valve in the pipe 26 indicating the pressure within the pontoon. When the desired level of the, dock has been reached the flow of air into the pontoon may be stopped by operat ing thevalves 80, whereupon the dock will float at the desired level. The air vents 33 with their corresponding pipes 34 are controlled by means of valves 35 and are sup plied with gages 36 in order to indicate the air pressure within the pontoon.

By the method of control above described the series of pontoons may be operated simultaneously and submerge or lift the dock to any desired level, the device indicating at all times the exact pressure of air and water within the pontoons, so that a proper raising and lowering of the dock may be effected. In will'be further understood that upon the emptying actionof the pontoon the the water out.

watervwill also flow out through the valve device 82 in addition when the pressure overcomes the closing tendency of the spring 51, thereby expediting the evacuation;

Having thus described my invention what I claim as new and desire to secure by Letters Patent is i 1. In a floatingdry dock, in combina tion, a main deck comprising a plurality of members spaced apart,separate pontoons carried in fixed position by said members in the spaces formed therebetw'een, valves at the top and bottom of said pontoons, a

source of compressed air connected with the upper valves, and controlling means for opening the lower valves by means of com" pressed air to allow water toenter. the pontoon or to open both the upper and lower valves to force the water out of the pontoons by means of the air pressure.

2. Inna floating dry dock, in combination, a main deck comprising a plurality of members spaced apart to form a cratelike stru'cture, a plurality of separate pontoons carried in fixed position by said structure, a

machinery deck having a controllingtmeans, a main source of compressedalr controlled thereat, pipes leading therefrom to said pontoons, and valves associated with each pontoon whereby on actuatlng said control ling means one valve in each pontoon is opened to permit an inflow of water or if filled with Water to admit compressed air to the pontoon through another valve to force FERNANDO swim) Y XIMENEa
