RICHARD POWELL, OF VASI-IINGTON, DISTRICT OF COLUMBIA.
iMPRovEMEN-r IN IRON vEssELs.
Specification` forming part of' Letters Patent N0.V 153,375, dated July 2l, 1874; application lih d October 23, 1873.
To all whomy 'if may concern Be it known that 1l', liienAnD PownLL, of the city of lfashington, District of" Columbia, have invented certain Improvements in the Manner of' Building I ron Vessels, of which the following is a specification, reference being had to the accompanying' drawing and the letters of reference thereon.
The drawing shows sections of the side of a ship and details of' the mode of'V building', herein described, with designs f'or tools.
The letters of reference in the specification will fully explain the drawing. l
The objects of my invention are, first, an improved plan of' constructing the hulls of' iron vessels, so as to have a f'air and smooth outside surface; second, to secure wood backing or filling, for the reception of wood planking to be covered with copper sheathing, so that none of' the fastenings will pass through or penetrate the outer iron plating or skin of' the vessel, particularly in the portion to be immersed; third, to lessen the rollin motion of iron vessels, with advantage to their speed, steering, &c.
To secure the first object (a fair outer surface) I attach to the timbers seam-straps, running fore and aft, for the reception of' the outside platin 0. rIhese seam-straps are `rolled with a tongue in the center for the plating to seam against. The thickness of the tongue should be about the same as that of` the plating, and its depth, in and out,about one-tenth of' an inch more. Where the plating is heavy, the edge ofthe tongue is to be rolled hollow that is, the edges should project an eighth or a tenth of' an inch beyond the surface of' the plating, and the hollow or center of' the tongue be on a line with the surface of' lthe platine'. (See Fie'. 6, A.) These projecting edges are dressed down into the seams with a roundf'aced hammer, thus filling and calking both seams at the same time, leaving little if any trimming. The outside plating is riveted to the seam-straps in the usual manner. Where light plating is used, the tongue ofl the seamstrap maybe square on its outer edge, projecting, say, a tenth of an inch, as it can be dressed down with a hammer, calking the seams without bruising the plating, making smooth work with little or no trimming. The
seams can also be calked by setting a sharp cold-chisel into the center of the tongue, opening it sufficient to fill the sea-ms, after which the score, Fig. 6, B, will be filled with putty, when painting. It calked in this way, the
tongue of the seam-strap must be rolled full the depth of the outside platino'. This will require no trimming. When the plating and tongue are heavy, two scores, Fig. 6, B, will be necessary in calking, in which ease the After calking, angle-irons are riveted to both q sides ofl this projecting tongue, (see Figs. l, 2, and 6,0,) which must project sufficiently to receive half the thickness of the wood filling within the angle-irons. The wood filling or backing between the tongue-stringers is to lie close against the outside plating of' the hull, the ends being grooved to fit over and within the angle-irons on the tongued seamstrap. (See Figs. l, 2, and 3, D.) of' this filling reverse their angle, bracing each course, as shown in the dra-wing, Fig. l, I), the angle to be not less than the width ofthe widest timber used in the filling. set off on a square on the opening to be filled. An angle of' not less than this is necessary to insure good work in fitting and getting the timber into place; but it should not exceed forty-five degrees. Every third piece of' filling should have a short bolt, d, driven through the angleironsinto each end, the upper ends of the upper course finishing under the double angleiron, shown at E, Figs. 1, 2, and 3, the bolts to be driven through its outer face. The purpose of' these fastenings is to resist the calking. To facilitate the driving of' these bolts all the courses mustbe filled at the same time. The upper edge of' the double angle-iron must be riveted to the outside plating of the vessel. The calking of' the filling should commence The pieces at both ends of the courses at the same time, and all of the seams in -the courses be calked before the butt seams running fore and aft over the seam-straps.
After being calked and pla-ned oii' fair, if desired, the sheathingcopper can be put on the filling; but for first-class Work, the filling should be covered with sheathing` boards or plank, and this also calked and planed oir' before putting on the sheathing-copper. (See Fig. l, F.) A
This system of sheathing can be applied to vessels already built. For such vessels a double angle-iron (see Fig. 2, G) must first be riveted to the plating and frame of the hull. A single angle-iron is then riveted to this double an gle-iron, and the wood filling or backing is iitted and Worked, as before described.
The mode of casing the keels with Wood and securing the filling or backing thereto is illustrated at .T and K of Figs. 2 and 3 of the drawing.
To secure the third object of my invention, to lessen the rolling motion of iron vessels, I use a seam-strap with ton gue-Stringer, as a1- readydescribed. (SeeFig. 5, H.) The stringer here shown projects outside the plating, forming keels on each seam from the main keel to near the Water-line. These sidekeels may be formed on the alternate seams only, as may be advisable, according to the form and Width of the plating of the vessel. These stringers, by their depth' and number, will keep the vessel steady, and prevent the rolling motion. Their projection, clear of the outside plating, must vary according to the size and form of the vessel, say, from six to twelve inches. They form bilge-keels, and there is no danger of their carrying away or straining the plating, the number of them giving little or no opportunity to roll, and consequently there is but little strain on the stringers. Oscillation being prevented, the propelling power can be used to its full extent. These outside stringers or keels are 4to run along the main body ot' the vessel, for, say, three-iifths of the length of the vessel on the water-line, and be rounded oi'l' at the ends. They will thus make but little if any resistance to the free passage of the vessel through the water, While, by keeping her steady, there will be a marked clicct 011 the steering' and speed, the strong transverse friction of rapid rollin g being avoided. The number and position of these strin gers, also serve to strengthen the main body ofthe vessel Where strength is most needed, and protect the outside skin should she touch the ground. The edges of the plating having their bearing against the stringerare moresubstantially seA cured than when they seam against each other. The Stringer, giving a fair iirm base for either side, acts also as a stiii'ener betweenthe frames for calking. On this account the stringers usually placed on the inside ofthe hullcan be reduced in size, so that the outside stringcrs need not be Wholly an additional Weight to the hull. This T-iron strin ger can be applied to vessels already built. In this case it must be laid on the outside and riveted through every frame it passes over, in the manner shown at I, Fig. 4.
In building with the seamstrap tonguestrin ger, the frames can be spaced farther asunder than is usual, reducing the weight almost as much as the seamstrap will increase it, and make a much stronger vessel in very nearly the same Weight ot' material.
In using the seam-straps and tongues, the plating is increased in width by the amount of the laps and tongues, and the number oi' streaks of `platin g is thereby reduced.
What l claim as of my invention, and desire to secure by Letters Patent, is-
1. A tongued seam-strap, the tongue being rolled hollow on its outer edge, and adapted to be lcombinedin the manner herein described with the plating of iron vessels, so as, when dressed down with a round-faced tool, to calk the seams and give a smooth surface, substantially as set forth.
2. The method described of calking the seams in iron vessels by scoring the tongue ot' the seam-strap, substantially as shown and specified. f
3. The combination of angle-irons and sea1nstraps, for the purpose of securing Wood backing, in the mannerset forth and shown.
4. The Wood backing applied in a diagonal position, for the purpose of strengthening and bracing vessels, in combination With the an gleirons, substantially as shown and described.
5. In iron vessels, the T-iron, constituting strin gers and seam-straps applied in the manner described, for the purposes set forth.
In testimony that I claim the above I have hereunto set my nainein presence ot' two witnesses.
RICHARD POWELL.
