IMPROVEMENT IN ANCHOR-TRIPPERS.

Specification forming part of Letters Patent No. 179,731, dated July 11, 1 876; application tiled March 3, 1875.

To all whom it may conccrn: v

Be it known that I, RALPH G. SANDES, ot' the city ot" Chicago, in the countyv of Cook and State of Illinois, have invented a new and useful lmprovementin Ship-Building,of which the following is a specification:

This invention relates to a new and important device for safely and expeditiously dropping the anchor ot' a ship or other craft or vesselcarrying an anchor; and consistsV in the device ofthe double bolt, and in the combination and adaptation thereof with and to the catches and connecting-chains, as hereinafter described. y

The accompanying drawing represents a horizontal View of my invention as permanently attached to the rail and cat-head of a shin.

Similar letters ot` reference indicate corresponding parts.

A A A is a metal bolt, shooting double. B B is a metal plate, fixed permanently to the rail and cat-head, upon which plate the double bolt is fixed and slides. G is the rail, and D is the cat-head, ot the ship. E is a catch, at. tached to the end of the ring-stopper K. F is a catch, attached to the end oi' the shankpainter L. These catches E and F are links suttlciently elongated to pass up through suitable ways cnt through the rail and cat-head, respectively, and through the bolt-plate, and when the ends of the-doublebolt are shot through them, respectively, they are so held in place, and, in connection with the ringstopper K and the shank-painter L, hold the anchor in position, clear ot' the rail, as represented by I. G is a knob on the bolt A A A,

position'clear ot' the rail, this pin H is withdrawn, and then the respective ends of the double bolt are withdrawn from the catches E and F at once and together, by a blow of a maul on the knob G, sufficient to move the bolt, so that its ends are driven from and release the catches, and the catches E and F, being so released, pass instantly and simultaneouly through their respective ways in the rail and cat-head, and the anchor, being thus` at the same instant freed from the ring-stopper K and the shank-painter L, drops instantly, in a nearly horizontal position, into the water, free (except of its chain or cable) and without a possibility of fouling.

Having thus described my invention, I cla-im as new and desire to secure by Letters Patent- The combination, with the rail C and cathead D, each provided with a lnortise to admit the catches E and F ofthe anchor-snpporting chains, ot' the double bolt A A, provided with the knob G, and secured to the plates B B, so as to admit of a longitudinal movement, whereby the ends ot' said bolts are adjusted within the said catches or disengaged therefrom, substantially as specitled.

' RALPH G. SANDES.
