CHARLES PERLEY AND JOSHUA TERRY, OF NEW YORK, N. Y.

IMPROVED SHANK-PAINTER STOPPER.

- Specification forming part of Letters Patent No. 6,509, dated June 5, 1849.

greater security to a ships anchor when either stowed at the bows or when cast off from the shank-painter and hanging by the cat-head for use, as ourimprovements are equally available to both these positions of the anchor, and in both these cases combining greater safety to the ships crew with increased facility for detaching or what is nautically termed letting go the anchor at a proper time, for

which improvements we seek Letters Patent of the United States; and we do hereby declare that the said improvements are fully and substantially set forth and shown in the following description and in the drawings annexed to and vmaking part of this speciication wherein- Figure l is a plan. Fig. 2 is an elevation, and Fig. a section, as through the line A B of Figs. 1 and 2, showing collectively a cathead stopper as in place and in use, oonstructed with our improvements. The application of the same as a shank-painter stopper, being only to the side of the bows instead of on the cat-head, need not be shown, as it is well understood.

The same letters and numbers, as marks of reference, apply to the same parts in each of the several figures.

In the drawings, C is the oat-head fitted with a side plate a, having a flange b partly overlying' the cat-head and partly projecting in front of and above the plate a.

1 1 are bolts going through the cat-head to secure the plate a.

o c are projecting lugs or ears to carry the pin 2, forming the center for the dog d between the lugs c c. On the iiange b is a lug 3 to form a jointe with the lock-piece e, which is made with a mortise 5 to receive the point of the dog d, which passing up through the mortise has a hole G to receive a padlock. (Not shownin the drawings, but fora use hereinafter noted.) On the iiange b are two fillets 7 7, the back ends of which are in Contact with shoulders or ears S S on each side the lock-piece e to take all strain from the joint 4. On the -lock-piece c is a lug 9, taking a chain 10, carrying a pin 11, which goes through a tongue 12, descending from the lock-piece e. The ends of the pin 11 take into hollows in the upper part of the bracket-lugs ff, under the iiange b.

g is a bolt going through the flange b and the cat-head, with an eye beneath to take the fixed end of the stopper-chain h, which goes through the ring 'L' of the anchor and finishes with a ring 13, to lie between the dog d and the plate a, but so as that the weight of the anchor, when catted, is borne principally by the lugs c c, the dog d merely preventing the ring 13 from slipping od the lugs. When thus made and in place, on removing the pin l1 from the tongue 12 and using the chain 10 and lug 9 to lift the lock-piece e, the dog CZ will fall outward and downward, the anchor being hoisted by the cat-tackles, as-uSual, until the chain h can be passed through the ring z' for the stopper-ring 13 to pass the dog d through it, which at this time will bein the position shown by dotted lines in Fig. When the ring i is so in place and passed up onto the lugs o c, the dog d is to be turned up and the lock-piece e turned over it for the point of the dog to pass through the mortise 5 in the locking-piece e. In this situation the dog and locking-piece will hold the anchor under nearly all or ordinary circumstances;

, but to guard against accident the pin 11 is put through the tongue 12, and to guard against willful mischief, particularly when a ship is laid by at a wharf, a padlock may be put through the hole 6 in the point of the dog, which will render the let go of the anchor impossible, exceptby a violence that shall t'ract-u re the parts. The contrary of this takes place when the anchor is to be let go shipshape, as a sea-man or boy can detach the pin 11 from the tongue 12, and standing ready with the pin 11 and'chain 10 in his hand can snatch up the lock-piece e at the moment the order is given, and the anchor is instantly gone to its proper duty, and al1 these operations are performed with less personal risk or bodily labor than by any other means we are acquainted with that are now in use for such purposes.

The chain 7L may be either lengthened 01:

the crown end of the anchor and serve as a shank-painter and stopper.

these purposes are publicly known, such as the one known as Burtons cat-head stopper, in which the eye of the stopper is suspended on one end of a pin that moves on a center, with the other end held by a clamp or Species of trigger held by a pin. In that apparatus the pull of the stopper on the bolt throws the strain of the weight back on the pin holding the clamp or trigger, so that a handspike is needed, by which one man takes off the strain by nipping: the clamp, while the pin is withdrawn to let go 'the anchor, making two operations, probably requiring two men to effect them, and in any case riskpainter apparatus, known as Spences, we' consider the same inconveniences to be manifest, as the end of the shank-painter is taken by a pin and joint that is held by a hooked lever, which is kept in place by a pin, andi the strain of the weight on the lever causes i the need for a bar or handspike to berentered in a hollow end of the lever 'to cant that be fore the holding-pin can be detached and 'the anchor let go. This, again, apparently requires two men, and is liable toall the same@ risk and inconvenience with Burtons,before referred to, and particulaly so to the men holding the lever. Ve do' not know that either of these inventions is now in usey; but we use a public description of them to show wherein we consider our apparatus as essentially differing with both of these, and, in fact, with all other apparatus for the same purposes that we know oftirst, in the factl that the places, shapes, and substances of the parts, as we believe, completely protect them vfrom accidental injury, so that the anchor cannot be let go by -such causes; secondly, that if by any motion of the ship or by the flukes of the anchor fouling another vessel or object the strain is thrown from the lugs c c to the dog d, this cannot cant the lockpiece e upward and release the nanchor, even if the pin l2 is not in place; thirdly, through the construction and by the facility of locking the dog e by the hole 6, no interference.

short of breaking the parts can release the anchor improperly; fourthly, in all cases, We are aware that many contrivances for whether of intended use or positive accident, the ultimate strains are not borne by movable and easily-detached parts, as all such strains fall on the fixed fillets 7 7, through the lugs vor ears 8 S, lindependently of any wear or looseness'in the joints formed by the parts 3 and 4,and, finally, the fact that either asa cat-'head stopper or shank-painter stopperthe-action of the apparatus can in almost all cases be fully controlled by one man, does,

Jas we believe, distinguish and separate this our invention lfrom all others that have either preceded it or are no` in use.

Ve do not claim to have invented any of the foregoing parts irrespective of the manner in which `we have arranged and applied them for 'these purposes; but

Vevdo claim as new and of our own invention, and desire to secure by Letters Patent of the vUnited States- The application, arrangement. and combination of 'the parts described and shown, by which the lock-'piece e, with ears or shoulders 8 8, places any ultimate strain upon the fixed llets 7 7 and through the lug l2 and pin 1l secures all the operative parts from moving by accidental causes, at the same time providi-ng means, through the attached'chain 10, by which one man lcan release or let go the anchor without other manual help and without other mechanical aid than that furnished by the parts attached and employed, when constructed and 'combined substantially in the manner described and shown.

In witness whereof we have hereunto set our signatures this 3d day of April, 1848.
