Definitions
- the floating dry dock is intended to raise vessels for the purpose of repair; it is composed of several rectangular sections or floating platforms; their number varying according to their size and the weight to be raised, and united together by means herein afterward described. These sections are alike in form and size.
- each section is a hollow rectangular parallelopiped or ioat, say, fifty feet long, twenty feet wide, and five feet deep, more or less, constructed of strong timbers, with all its sides, the top not excepted, impervious to water; or is composed of several hollow vessels, each water-tight, and all firmly united together, so as to form a float of the size just mentioned.
- this float is represented as consisting of two hollow rectangular vessels, each, say, twenty-live feet long, twenty feet Wide and five feet deep, more or less, similarly constructed and connected lengthwise; when reference shall be hereafter made to this part of the section the said formation will be presumed.
- This framework In order to secure the stability of the flood it is incased within a framework, to which it is firmly bolted.
- the bottom of this framework consists of cross-beams, each about one foot in breadth and depth, and upon these at right angles the hollow vessels rest.
- Figure l represents the side view of a section, a, a, a', c6', a, a., being ythe ends of the said cross-beams.
- Two of these beams, a a are at the middle o-f the section, about one foot apart, the rest being distant from each other eight feet, more or less; their extremities are secured by joints and bolts to posts, Ab, Z), Z), b, ZJ, of the same breadth, and, say, half the thickness.
- the posts are of sufiicient height as to admit of their being similarly secured to the extremities of crossbeams, c, c, c', c, c, c, laid across the top of the float at right angles to the posts.
- A, A, A is a distance sufficient to admit a longitudinal beam, B, B, say, twelve inches broad and eighteen inchesvdeep; this beam (and, be it observed, that the framework on both sides of the section is similarly and equally constructed) rests upon the crossbeams, a, a, &c., to which and also to the posts, b, Z), &c., it isjconnected by bolts.
- this beam B B, a truss C C rests, suitably fastened by joints yand bolts, and
- This truss supports another longitudinal beam or string piece E E, of ,the same breadth and depth with that of the lower B B; it is of the same length as the float A A A, and made fast with bolts to the posts andupper cross-beams, c, c, &c.; its upper surface being on a level with the upper surface of the flo-at, and thus regulating the height of the truss C C.
- the sides of 'the framework are more firmly bound together by braces Q Q Q Q, &c., laid across the float, between the cross-beams, and fastened with bolts to the longitudinal beams.
- the iooring or deck, (Z d, is formed of plank resting on the cross-beams, but isleft open over the space, e, between the two central ones, c', c. Across this space the keelblocks, F, F, F, are laid, and made fast with 'l bolts to the central cross-beamsupon which they rest. There are several keel-blocks on each section, say, one near each'end of the central cross-beams, and a third over the dinal beams, E E, B B, that lie along the sides of the float, so that their outer surfaces are, or are nearly, in the same plane with the outer surfaces of the longitudinal beams.
- ano-ther post, Z Z may be erected, of the same dimensions with the corner-posts@V g', Vand fixed to the longitudinalbeams exactlyin the sanie'manner; Vthese posts Vare for the purpose of.
- the lower braces make an angle of, say, twenty degrees'with the longitudinal beams, and are joined to the end posts at the height"of, ⁇ say, nine feet.
- the upper braces are joinedI to theA end Vposts. at the height of, say, eighteen feet, and tojthelower braces at an angle of, say, It is only meant to specify the fact that the parts'just mentioned are firmly bound together, as the manner may be varied. y
- the endfloats, ⁇ R R, R R, Fig. 2, or S, Fig. 3, are -hollow rectangular vessels built of strong timbers according to their size, and impervious to water on ⁇ all sides, the tops not excepted :r they are entirely sep'- arate, and movable vertically within the framework.
- Their breadth, measured with the breadth of the main float, is suchjthatA they rest, when lowered, upon the'low'er longitudinal beams B, B,Figs.
- Twoposts, m, a are secured within each corner of the end-float frames, close or near to the corner posts of said frames, each presenting an interior surface, twelve inches broad, more or less, at right ⁇ angles to each determined, the length ⁇ and breadth of the end-floats.
- metal racks To each ofthe four posts, a, e, a, a, on whichthe end rollers run, and p to the sides onV which they run, metal racks,
- pawls, 2, 2, 2, 2 are fastened, but'so as not to interfere with the rollers; pawls, 2, 2, 2, 2, are ,fixed on the tops of the end-fioats, opposite Vtothe racksgand by means of these pawls the 'end-floats, when 4depressed into the water, are retained at any desirable depth.
- the length of the end-floats isfless than theobreadth, but their length is indefinite, and the greater it is, the greater will be the buoyant power of the section.
- the length of their side framework varies with the length of the end-floats.
- teeth of these racks are, or are nearly, in a line ⁇ equidistant fromV the two nearest corner-posts, g g, f f; andtheir surface is, likethe surfaces of theracks already mentioned, parallel to the ends of the section.
- a lwinchis xed On or near the central part of the top of each end-float, a lwinchis xed, at a ⁇ convenient height and ofany suitable gearing.
- U consists of two -'cov"g ⁇ wheels,'the smallerv givingl motion tothe larger.
- the axis, 5, 5, of the larger cog-wheel is extended and supported Vbygudgeons,.6," ⁇ 6, fastened tothe topo-fthe end-float. .On the ends of this axis smallIcog-wheels, 4, 4,. areiixed, and
- YA stoutV rect' ngular frame or stand the corner'posts'v of which, K, K', K, ⁇ K, are, say, each twelve inches in breadth and thickends of these stands are parallel to the ends of the deck, at the distance of twelve inches, more or less; and their sides are distant from the sides of the deck, four feet, more or less.
- Their height is, say, live feet, and should not be less than the depth of water drawn by the vessels which are proposed to be raised upon the dock.
- the length of the stands is nine feet, more or less, but this length is indeterminate, and in no fixed proportion to their breadth.
- These stands are for the support of retangular reservoirs, J, J, the corners of which rest upon, or are near to, the corner-posts of said stands. Should the said cornerposts not rest upon the cross-beams on which the deck is laid, additional cross-beams P, P, should be laid on the float, in a line with and directly under the said corner-posts; and to these cross-beams the stands are firmly bolted.
- the reservoirs, J, J are built of strong timbers2 and secured to their stands with dogs or bolts, u, u. Their height is, say, seventeen feet, or such that the capacity of each shall be equal to, say, from one-fourth to one-third the capacity of the main-float, A A A.
- the reservoirs, J, J are filled by means of pumps fixed Within them, and worked by perso-ns standing on the yboards that cover the said reservoirs.
- there are two pumps, a', z, Fig. in each reservoir the diameters of which are, say, four feet apart, and equidistant from, or close to, one end of the reservoirsayJ the end of the reservoir farthest distant from the center of the sect-ion, as in Fig. 4,-or they may be thus situated at any side of the reservoir, so that the pipes, e', a, which feed the pumps, do not interfere with the lever, B B, Fig. 2, which moves the coupling-timbers, as afterward explained.
- a heavy pendulum, r, Figs. 1, 3 and 4 is attached, which moves as near as may be to the end of the reservoir, and serves to aid and regulate the action of the pumps.
- the pumps are fed by pipes, e e, Fig. 3, which are led perpendicularly through the bottom of the reservoir, the deckv and the' top of the main-float, into a small cistern, that is xed within the main-float, directly under the pumps; all its sides, the top not excepted, beingimpervious to water.
- a small cistern that is xed within the main-float, directly under the pumps; all its sides, the top not excepted, beingimpervious to water.
- an-air-pipe, s is led in any manner to the top of the reservoir.
- Another pipe, t, Figs. l and 3, which feeds the cistern is led fromits interior through the side of the main float at any convenient point, say, aboveand close to the lower longitudinal beam, B.
- a perpendicular rod, u accessible with the hand from the top of the reservo-ir, lies along the outside of the reservoir, passing through the deck and ⁇ top of the float, in the direction of the inletpipe, t, and serves as the handle ofav cock or sluice-gate that is fixed in the said pipe ⁇ at this point; this cock or sluice-gate is used to stop the ingress of the water and enable all the water to be pumped out of the cis-y tern; it is called the cistern-cock or sluicegate.
- Another pipe, e, Fig. l leads from the interior of the cistern to the interior of .as the rod or handle, u, already described.
- the cisterns are'each as small as may be; but of a size sufficient to admit the pipes described, and to admit a volume of water sufficient to feed the pipes connected with the pumps. All the aforesaid pipes, where they pass through the timbers of the main float, the reservoirs, or the cisterns, are to be fitted into the said timbers so tightly that the said 'reservoirsJ cisterns, or main-float, may be each separately still impervious to water as hitherto described, excepting through the said pipes as already explained. No water, leakage excepted, is ever inside J[he main-float. To let the water out of the reservoirs, there is an opening, n, Fig.
- valve or gate at the bottom of each, at any convenient point, covered by a valve or gate.; and to the said valve or gate there is a rod or ropeJ d, el, fixed, stretching to a point accessible with the hand from the top of the reservoir, and serving to open the said valve or gate.
- stanchions are above the longitudinal beams, E E, B B, of the float frame work, mortised through both, and through the truss timber, C vC, if necessary,V and secured with At the ⁇ height'of, say, eightinches above the deck, they are'bound together by l a timber or tiet-piece, secured byjoints and v deck and between the stanchions and tie-V Y a horizontal joint fixed to the deck.
- coupling-timbers are at right angles to thev plane of contact, and extendfrom the stanchions to an equal distance on the deck of each adjacent section, say, eightfeet, more or less; at the .distance of, say, two feet from each end, the said coupling timbers being secured Vin a direction atright angles to the side of the deck by iron bands or by bolts, y, y, y, y, Fig.
- each may be moved by a lever of the secondv order B B, theffulcrum of which is There is a lever of'thiskind at both ends of each coupling-timber; one on one section, and the other on the section adjacent.
- the lever is not jointed tothe couplingftimber, but passes through an iron band or between two bolts, casserole, fastened to its end.
- the handle of the lever projects toward the nearest end-fioat, but does not touchit; to its endv two ropes are attached which run separately through tackle-blocks just xed to the extreme cornerposts of the reservoir-stand, or to the deck, asfmay be judged most convenient.
- These ropes may be pulled, and, consequently, the sections 4may be farther separated or ⁇ brought nearerjjeach other, byV per ⁇ sons standing on the topof theend-float:
- the vessel is then floated over the keel-blocks, and the bilgeblocksl brought tobear, as much water ⁇ being allowed to escape from the reservoirs or end-floats, as may be necessary in order to eect anequal pressure of thebottom of:
- the vessel upon all the keel-blocks and bilge- The reservoir-cocks or sluice-gates, which are all ofjan equalaperture, are then simultaneously opened, andthe water allowed to escape.
- the endefloats are emptied in the same manner, and at the same time; as soon as empty, their cocks are shut, and they are forced downward into the water, simultaneously and equally, by the machinery already described, as far as the said ma- Y chinery willpermit. ⁇
- thevessel may be then shored ⁇ in the usual way. ⁇ From this description it is plan that the distance between the reservoirs of each section, ⁇ limits the size of the vessels to be raised bythe dock, as far as the breadth of the vessels is concerned.
- adock may be con- ⁇ structed to receive vesselsof the largest size.
- the power and buoyancy of each seotion may be illimitably increased by increasing the length of the end-floats; the increased weight of the timbers comprising the said end-floats, and the increased weight of the water within them, at the same time materially helping to sink the dock, whenever it may be required.
- the size of the end-floats may be such that the weight of them alone, and of the water Within them, would be sufficient to sink the dock, Without the aid of the reservoirs.
- the size of the reservoirs may be diminished in proportion to the increased capacity of the endloats.
- a variation of the manner may be necessary in constructing the end-float framework, but this variation any carpenter will readily determine.
- two or more end-floats may be advantageously constructed at each end of thesection.
