licite/rs Patent No. 106,487, elated .August 16, 1870.

The Schedule referred tqn these Letters Patentrandvnraking part'of the same.

To all persons to whom these presents shall come: l

'Be it known that I, WILLIAM CARLTON' IRELAND, of Boston, in the countygof Suffolk and State of Massachusetts, have invented a certain new and useful improved Elastic Connection or Coupling for Standing Rigging to Ships, 85e., and that the following is a full and 4exact description of the saine, referencebeing had to the accompanying*drawing;

The object of this invention is to connect the bowsprit, futtocks, and nnist-sln'onds or stays, or, in a word, -the standing rigging of ships, more especially to the ships sides, in such manner lthat, whilepermanently fastened, the shrouds or ropes can yield or give to heavy strains or tensions ou them, preventing breaking. Y

For this purpose the invention consists of a coupling between a dead-eye, in which -one end of the rope or shroud is secured, and the ships side, which coupling is an extension of the dead-eye, and, in its lengt'lnis` so constructed between the dead-eye and the eye, loop, or bolt, by which it is hung or fastened t0 the ships side, as to yield or give in such direction to heavy strainsor tensions on the shrouds or ropes.

In theaccompanying drawing my improved elast-ic crmnection or coupling for standing rigging.; of "ships, Sie., is illustrated, Y

Figurel being, a side view of the saine, and

Figure 2 central longitudinal section.

Ain the drawing represents one end of a rope or shroudand v B, a dead-eye, in and to which the rope end A is secured.

This dead-eye B I prefer to have constructed according to an invention described in schedule annexed to Letters Patent N o. 100,976, dated March 22, 1870, and issued to Dexter H. Chamberlain, that is; in two parts, O and D, thc `one O a receiving-part, and the l other D a fastening part, with a hole through the center of the receiving part and the fastening part arranged to hold the cable in a line outside of said center hole,'bindingtl1e same on the receiving-block in a direction transverse to the receiving plane.

E and F, cross-bars, the one placed across the end G. of receiving-part C of 'dead-eye, the cable passing through a hole, H, in its'center, and the other placed across-the end Lof lfastening Vpart D, with the two joined together or connected by and through two boltrods,-K K, on which are screw-nuts, L L, by the proper turning of which the cross-bars E and F are forced `toward each other or allowed to separate, as the .case

may be, in the one instance binding. the two part-s of the dead-eye irmlytog'ether, and in the other allowing them to separate or beopened.

M M, extension of the bolts K K from the crossbar F.

N, a series of India-rubber or other elastic cushions, cylindrical in shape, and, inthe present instance two in number.

The rubber cushions N are placed over the extensionM of bolt-rods K, with a plate, O, placedrbe.- tween the two, separating them, and with a plate, P, against eachend of the Vwhole series, through all of which plat-es the said bolt extensions M pass.

Q, nuts on the extreme ends of the bolts K, holdv ing the said series of cushionsand plates on the bolts.

above described is to be securedto the ships side,

and, for vthis purpose, as is obvious, it may be'constructed as an eye or a screw-bolt, or in many other forms.- l

IVith a shroud fastened in the dead-eye B, the end T of rod R secured to the ships side as the shroud strains, the rubber cushions on the dead-eye extension-rods'Kare compressed, when the strain, beconiing released more or less, or ceasing, the cushions iminediately react, and so on; the connect-ion or coupling described yielding and giving to strains on the shroud, and` therebypreventing their breaking or the giving away of the attachment to the ships side.

By constructing the rubber cushions or yielding portions of the coupling in sections, separated by a plate, O,"as`describefd, a lnore perfect action issecured, and thebulging of the rubber by compression greatly reduced fronrwhat would occur with 'rubber cushions made in one entire piece or length, and a con.- sequent better confinement of the rubber to its-work, and an` increased durability thereof secured.

In conclusion, it maybe well to here observe that l the coupling, substantially constructed and combined as he'rein described, maybe used for other purposes than the standing rigging of ships, and, therefore, it is not intended by me to limit myself to any one or more purposes of its applicatin.,

Having thus dcscrifbed my invention,

What I claim, anduiesire to secure by Letters Patent, s

The rods'K K, connecting together the plates E and F of the dead-eye, when combined and arranged with the plates, P, and rubber N, sliding upon the extensions M M of the bolts E. K, and operating in relation tothe cable A, and rod R, substantially in the man ner and for the purpose described.
