COTTER T. BRIDE, OF WASHINGTON, DISTRICT OF COLUMBIA.

REINFORCED SHIP.

To all whom it may concern:

Be it known that I, CorTER T.- BRIDE, a citizen of the United States, residing at Washington, in the District of Columbia,

have invented certain new and useful Improvements in'Reinforced Ships, of which the following is a specification, reference being had therein to the accompanying drawings.

This invention relates to the construction of ship-hulls of concrete or other material the aggregate of which is handled in a'plastic state and sets after being molded or otherwise shaped in place in association with reinforcements.

It is an object of the invention to provide reinforcement for such a structure that will afford sufiicient strength to the hull both longitudinally and transversely.

The invention also contemplates the provision of a double hull-reinforcing frame and means whereby the outer and inner portions thereof are tied together.

Further, it is an object of the invention to 5 provide a reinforcing-frame that can be assembled to a great extent by unskilled labor with standard metal elements, whereby the cost is materially less than would be the case where special shapes are requiredandrivet- '30 ing and similar work involved.

l/Vhen read in connection with the description-herein, the details of construction and arrangement of parts contemplated by the invention will be apparent from the ac-' companying drawings, forming part hereof, wherein an embodiment of the invention is disclosed, for purposes of illustration.

'While the dlsclosures herein now are considered to exemplify a preferable embodiment of the invention, it is to be understood that it is not the intention to be limited necessarily thereto in interpretation of the claims, as modifications within the limits of the claims can be made without departing from the nature and spirit of the invention.

Like reference-characters refer to corresponding parts in the views of the drawings, of which Y Figure 1 is a plan View, the filling of the upper deck being-broken away in part;

Fig. 2 is a side elevation, the filling of the hull being broken away in part;

Fig. 3 is a transverse sectional view; Fig. 4 is a perspective view of a portion of the reinforcing-frame;

Specification of Letters Patent.

Patented Aug. '6, 1918.

Application filed April 23, 1918. Serial No. 230,271.

Fig. 5 is a view of a portion of one of the, bars extending fore'a'nd aft;

' Fig. 6 is a'view of one of the tie'mem bers; and 1 Fig. 7 is a view of one of the obliquelydisposed brace members.

Having more particular reference to the drawings, 11 designates the keel, which may be of any suitable form, such as an I-beam as shown, and 12 and 13, respectively, the stem and stern-post, which are secured to the keel in any suitable manner commonly employed in ship-frame constguction.

An outer series of bars 14, preferably flat such as can be cutfrom sheet-metal stock of suitable thickness, are secured to and extend between the stem and stern-post; and an inner series of correspondingly-disposed similar bars 14 are similarly secured in substantially parallel relation to and spaced from the outer series. The bars are shaped in plan to give the desired breadth and contour to the hull between the bow and stern, the distance between their outer margins is somewhat less than the intended thickness of the hull, the bars are arranged in pairs of an outer and inner one directly opposite each other, and they are disposed at suitable intervals between the keel and gunwale.

The bars 14 and 14 are formed at suitable intervals with holes 15, and an outer series of rods 16 are disposed through, the holes of the outer series of bars and an inner series of rods 16 through those of the inner series of bars,the rods being at substantially rightangles to the bars. The rods are bent to conform to the athwart shape of the hull at their respective places of disposition, and they are'secured in their lower end portions into thekeel and ,stem and stern-post and in their upper end portions to 'a gunwale member" 17 extending from stem to stern-post on eachside of the hull.

The rods 16 and 16 may be secured in the keel and gunwale member in any suitable manner, as by having their end portions passed therethrough and then; bent to substantially right angles against the faces of those parts, as shown at a and b, Fig. 3.

- *In practice, particularly"with vessels of the larger sizes, it maynot be practicable to have bars 14 and 1 1: extending as single units from stem to stern, and, where shorter lengths are used, the parts may be connected by having end "portions overlapping and secured together by the rods 16 and 16 passing therethrough, as shown by Fig. 1.

In order to tie together the inner and outer frames formed by the bars 1 1 and 14 and rods 16 and 16, and to maintain the two frames in proper spaced relation, tie-plates 18 are embodied in the structure. Each of these plates spans the space between the two sets of bars and rests on and overlaps two opposite bars 141 and 1d, and it has a hole 19 in each end portion in which a pair of the outer and inner rods 16 and 16 are disposed. The tie-plates are disposed at substantially right angles to the bars.

For the purpose of preventing torsional movement between the outer and inner frames, apertured plates 20, similar to, but longer than, plates 18, extend brace mem bers obliquely at suitable int vals across each pair of outer and inner bars, with which they arelocked by having rods 16 and 16 disposed therethrough.

As a contribution to the maintenance of the two sides of the hull in proper relation and shape and to the integrity of the entire structure, bars or rods 21, disposed at suitable intervals beti een the stem and sternpost, extend from one side to the other, except at the hatchways, and they are locked in the frame at their ends by having rods 16 and 16 disposed therethrough. At places where the members 21 are locked into the frame, it is not necessary to use tie-plates 18, as the members there perform the function of those plates. At the hatchways, the members 21 are secured to hatchwayframes 22.

These athwart men'ibers 21 may be employed advantageously as parts and supporting elements of the decks of the vessel, on which planking can be laid, if desired.

If, however, it is desired that the decks shall have a filling of concrete or other initially plastic material, the members 21 also may serve advantageously reinforcing elements thereof, In such a case, it usually will be advisable, particularly in vessels of the larger sizes, to provide each deck with upper and lower transverse members 21.

here the decks extend between substantially vertical sides of the hull, as in the case of the upper ones, the upper set of members extend substantially straight across and in each side of the hull-frame rest on a pair of bars 1-4: and 14:, and the lower set of mem bers in their end portions rest on the neXt below pair of such bars. However, as the pairs of bars usually are agreater distance apart than the thickness of deck ordinarily required, the lower set of members are bent andeXtend upwardly adjacent to the inner side of the hull, as shown at a, in order to bring them'closer to the upper set, in parallel relation to which set they thence eX- t nd across the deck.

In the case of the "lower decks, of which one is shown in the present exempliiication of the invention, which extend between slanting portions of the hull, the two sets of bars usually are brought sufficiently close together in the decks as a result of the fact that their end portions are bent in order that they may be disposed at substantially right angles with respect to, and in, the hull structure.

' t usually will be advisable, particularly in vessels of the larger sizes, to employ lon gitudinally and obliquely disposed reinforcing-rods 23 and 21-, which extend into the frame and are locked thereto by having rods 16 or 16" disposed tl'ierethrough, and at places where necessary these rods are connected into the hatchway-frames.

A reinforcing hull-frame, such as a described, can be put together largely by unskilled labor, as it is composed for the most part of stock material that does not have to be specially shaped before being incorporated into the structure, and as no riveting or similar special work is involved in the assembly.

After the frame has been assembled, a filling of concrete or other suitable plastic material may be applied thereto and incorporated therewith in any suitable manner, such as by the use of molds placed on each side. of the frame or by the use of trowels or other tools, the plastic material being made to fill the spaces between the outer and inner frames and between the elements thereof and being smoothed 01f on the outer and inner sides, and preferably it covers the reinforcen'ient and thus makes the hull slightly thicker than the double frame.

It will be seen that the rods extending be tween the keel and gunwale members and the transverse, longitudinal, and oblique members of the decks give the. structure strength and rigidity in a transverse direction, that the longitudinally-extending bars of the hull-frame and the longitudinal and oblique deck members insure integrity of the structure in a fore and aft direction, and that the means of tying the two frames together add to the strength of the hull as a whole.

Having thus described my invention, wha I claim as new, and desire to secure by Letters Patent, is V 1. In a hullrein-forcing frame, an outer and an inner set of longitudinally-disposed bars arranged in separated relation, and upright rods disposed through each set of bars.

7. In a hull-reinforcing frame, an outer and an inner set of longitudinally-disposed bars arranged in separated relation, deck members extending from one side of the hull to the other and having their end portions spanning the space between said sets of bars, and upright rods disposed through each set of bars and through said deck members.

8. In a hull-reinforcing frame, longitudinally-extending bars arranged in pairs each of an outer and inner bar and the pairs beingdisposed in separated relation, a set of deck members extending from one side of the hull to the other and having their end portions overlapping a pair of bars on each side, another set of similarly-disposed deck members having their end portions overlapping the next-below pairs of bars, and upright sets of rods disposed through said bars and through said deck members.

' 9. A hull-reinforcing frame comprising the combination of a keel and gunwale members, an outer and an inner set of bars extending longitudinally of the hull in separated relation between the keel and gunwale member on each side tie members spanning the space between said sets of bars and disposed at substantially right angles thereto, brace members extending obliquely from one set of bars to the other, deck members ex- 3i tending from one side of the hull to the other and having their end portions spans ning the space between said sets of bars, and on each side of the keel an outer and an inner set of rods extending from the keel to a gunwale member through the outer and inner sets of bars, respectively, and through said tie and brace'and deck members;

10. In a vessel, a keel member, a stem, a stern-post, an outer and an inner set of bars shaped to define the fore and aft contour of the hull and extending from the stem to stern-post, tie members, upright rods disposed through each set of bars and through said tie members, shaped to conform to the transverse section of the hull at their respective locations, and connected to the keel member, and a filling of initially plastic -material in which said bars, tie members,

and rods are embedded and constituting therewith the sides and bottom of the hull of-the vessel.

In testimony whereof I aflix my signature.
