JOHN PENN OURRY, OF NEW YORK, N. Y.

IMPROVED CONSTRUCTION OF VESSELS.

Specification forming part of Letters Patent No. 48,795, (lated July 18, 1865.

To all whom it may concern:

Be it known that I, JOHN PENN GURRY, of the city of New York, State of New York, have invented a new and Improved Mode ot' Constructing Ships and other Vessels, adapted either to warlike purposes or our commercial marine; and I do hereby declare the following is a full, clear, and exact description of the construction and operation of the same, reference being had to the accompanying drawings, explanatory of the plan, and to the letters inscribed thereon, illustrating the various parts, making a portion ot this specification, in which- Figure l represents a side view of a vessel partially planked and partially in skeleton. Fig. 2 represents a top plan. Fig. 3 represents a side view, partially covered and partially not. Fig. 4 represents a transverse section through a vessel constructed after my plan. Figs. 5, 6, 7, 8, 9, and l0 represent detached portions, and on an enlarged scale, of some of the details ot1 the vessel.-

Similar letters and other marks of reference, where they occur in the separate gures, denote like parts in all cases.

I am aware that the frames of vessels have been made of tubular iron. This I do not lay claim to.

My invention consists in the peculiar manner in which I unite and combine the tubular frame with the wooden frame, planking, or exterior covering of the vessel, so that a combined tubular iron and wooden frame shall be made without puncturing the iron by the bolts that secure the planking or timber to each other, and by fitting and clamping them together to the iron frame, the effect of such combined framing being to allow the metal to expand and contract without straining the bolts or wood-work, while each frame takes its due proportion of the strain upon the whole. To enable others skilled in the art to make and use my invention, I will proceed to describe the same in connection with the drawings.

The material parts of the frame are designated as follows: A is a section of the plankshear; B, the stem; C, the stern-post; I), a

false stern-post; E, a section of iron plating; F, dead-wood and aprons; G, keelson; H, section of inside planking or ceiling; I, forward apron; J, thick strake or water-Way; K, section of' main deck; L, main deck and supplemen tal beams; M, forward breast-hook; N, main rail; O, timber fillings or chocks; P, the keel; R, wood timbers or riders for planking with wood; T, longitudinal or fore and aft iron pipes, crossing at intervals the vertical pipes or tubes.

Where the fore and aft tubes T meet or lie against the vertical tubes they are clamped together by straps, as shown in Figs. l, 3, 4, or by clamps, as shown at 5 9 in Figs. 6 and 8, and in all cases so that the metal tubes shall not be perforated or the fastenings pass through them, the ohjectof this loose or play fastening or clamping being to allow free eX- pansion and contraction ot' the metal without straining the tubes and breaking or loosening the fastenings. The form ot' these fastenings may be varied, but I have shown but three, which will fully explain the objects in view.

The timber fillings or chocks O are strapped to the tubular iron frame, as shown in Fig. 3, and also to the wood timbers R, and the plankingI and ceiling bolted to said timbers. The bolts passing through the timbers are so placed as that they shall not penetrate the metal portion of the frame, but closely embrace it between the timbers, so that it shall be a combined frame to resist strain, but leave the -xnetal free to expand and contract.

The spaces between the tubes may be lilled with wood, so `as to leave, in connection with the timbers,flush sides to plank or ceil to, and the frames may be double, with an intervening space, as shown in Fig. 4.

The stem-piece B, with its aprons l2 and 13, Fig. 5, is fitted to the tubular frame, as shown, and held in place, as also holding the tubes, by compression, the bolts passing through the timbers, but not through the tubes. The keel l0 and keelson 14 are here l represented as united to the stern-post. The same construction may be applied to the stern and stern-post and to the deck. Iron plating may also be used in connection with this coml expand or contract by atmospheric changes bined metallic and wooden frame. without injury to itself or to the fastenings of Having thus fully described andrepresented the Wooden frame, as herein described and my invention, What I claim therein as new, and'- represented.

desire to secure by Letters Patent is- A combined tubular iron and vood frame JOHN PENN CURRY' for Vessels, so united as to conjointly receive, In presence ofresist, or transmit the strain throughout the J. C. BABGOCK,

Whole, while the tubular iron fra-me is free to JOHN M. HARRINGTON.
