IMPROVEMENT IN SEnTTlNG UP SHIPS RIGGING.

Specification forming part of Letters Patent No. 29,204, datedV July 17, 1860.

To all whom, it may concern:

Be it known that I, EPHRAIM U. THOMP- soN, of Bristol, in the county of Lincoln and State of Maine, have invented a certain new and useful Apparatus for Setting Up Ships Rigging; and I do hereby declare the following to be a full, clear, and exact description thereof, reference being had to the accompanying drawings, making part of this speeltication.

My invention consists, first, in a device for grasping the ends of the shrouds, so that when the shrouds are set up every tiber bears its proportionate share of the strain. At the ,same time the ends of the shrouds are sheathed and protected from the weather, thus preventing their decay.

Second, in a peculiar construction and coinbination of lanyard andjack, for'tlie purposes hereinafter explained.

In the accompanying drawings` Figure l represents a front elevation ofthe lanyard and jack. or setting-up device. Fig. 2 is a side elevation of the same. Fig. 3 is a longitudinal section of the thimble, showing the end of the shroud and lid partly in section.

A represents the shroud.

B is a thimble attached to the end of the shroud.

a is a f'errule fitting the end of the thimble.

C is a iid formed of' hard wood.

D is a cap fitting the end of the thimble.

F is a screw-bolt passing through the cap D into the end of the tid C.

b represents ears or lugs cast upon the periphery of the thinible B.

e are metal straps fitting over the ears b, and attached to theupper end of the lanyard E by an eyebolt, c. The straps are prevented from spreading, and thereby slipping ott the ears, by a ring, d, fitting over their ends. The lanyard is formed of two pieces of metal, E E', tting one within the other, of which the upper portion, E, is attached to the shroud and the lower portion, E', to the ship. The portion E is a solid bar of iron flaring downward on two sides. The portion E is formed ot' two elastic bars fitting over the portion E, as represented, and united below it in a solid bar, f, adapted to be fastened either to the chain or to replace the chain and be attached directly to the ships side.

g are loose collars which fit over the two parts of the lanyard, and serve the purpose of locking them together in any position in which they may be set.

H is an iron bar constructed with a yoke, h, forming at its lower end a nut with a lefthand thread.

I is a yoke attached at its lower end to the partf ot' the lanyard by means of a bolt, z',

and forming at its upper end a nut with a right-hand thread.

J is a right and left hand screw fitting the nuts in the yokes H and I, and rotated by a lever, L, so as to cause the said yokes to approach or recede from each other, as desired.

K is a dog hooking over the top of the upper portion, E, of the lanyard, and attached to the bar H by any one of the holes li.

The operation is as follows: The thimble is first passed over the end of the rope. The latter is then opened and the lid inserted and the rope end hawsed down onto it, being careful to keep the strands in proper relative position. NVhen fitted snug onto the ftd, worm and parcel and serve as in case of other fitting. A compress, M,ofthin sheet metal is then y passed around, as seen in Fig. 3, its ends overlapping to permit its contraction upon the rope. Heave such turns as are needful in the rigging by means of the projecting end of the tid, and haul down the thimble to the position shown 4in the drawings, drive the tid home. and saw off the projecting end flush with the lower edge of the thimble. Next bore into the end ot' the iid and apply the cap D and screw F. Then dx the straps e to the thimble, as previously explained, attach the dog K and yoke I to the respective ends of the lanyard, rotate the screw J until the shroud is drawn thoroughly taut, and then drive down to collars g, so as to hold the two portions of the lanyard firmly in position. The jack H I J K may then be removed and the shroud will remain securely fixed.

I claim asnew and of my invention here- 11il. rIhe combination of the fid C and thimble B, constructed, applied, and operating substantially as and for the purposes set forth.

2. The lanyard E E', constructed and operating substantially as described.

3. The described combination of the jack H I J K and lanyard E E', operating as set forth.

In testimony of which invention I hereunto set my hand.
