UNTTED STATES PATENT IMPROVEMENT IN HAWSE-PlPES.

Specification formirg part of Letters Patent No. 176,562, dated April 25, 1876; application filed April 17, 1876.

To all whom it mag concern Be it known that I, PIERRE OELEsTIN-ST.

MARIE, of the city and district of hilontreal,

in the province of'Quebec and Dominion of Canada, engineer, have invented certain new" this specification. I

My invention relates to improvements in ships and vessels, the nature of which. will be fully understood by reference to the accompanying drawings, in which' Figure 1 represents a front view of so much of a vessel as will illustrate m'y invention. Figs. 2, 3, 4, 5, 6, 7 and 8 show detail views of parts separately.

In each of the viewssimilar letters of reference are employed to denote corresponding parts wherever they occur.

A represents a portion of the maindeck of a ship or vessel, upon which is erected a windlass, B, and the various devices for controlling and operating the same, and the necessary chains, cables, or ropes, as will be well understood by persons acquainted with nautical matters. 0 represents part of the forecastle-deck, upon which is mounted the capstan D, and also the davits E, which are provided with anchor-hanger chain-levers E pivoted to their heads. (Shown in detail by Figs. 2 and 3.) These levers E are formed with lugs or catches E adapted .to pass through the end link F of the anchoehanging chains F, when such chains F are passed through the ring g of the anchor G and inserted in the hole or aperture E as shown at Fig. 1, and also shown by Figs. 2 and 3. The levers E are held in position and prevented from accidentallyletting go of V the anchor G by means of safety-pins I, which are connected to the deck B by chains 1', as shown.

J J represent the chainstoppers, which are provided with hinged plates J 1 J pivoted to the bearings J,.forrned on each side of the front end of the stoppers J. The stoppers J are provided with grooves or channels J for the reception of the alternate linksof the chain G, for the purpose, of keeping the same formed, for the reception of the cross-links of the" chain G1 when sliding in the groove J L L are the chain hawser-pipes, which are formed with grooves or channels I, corre sponding with the grooves J in the chainstoppers J, for the purposepf guiding the chains through the hawser-pipes and preventing twisting of the same. The hawser-pipes L are also provided with guiding-faces L, for the purpose of keeping the alternate links of the chain K perfectly flat or horizontal, while the grooves l serve to keep the alternate links vertical, thereby avoiding all possibility of twisting or kinking in passing through the chain-stopper when heaving the anchor.

J are levers, pivoted to lugs J and provided with cam-surfaces J adapted to press the plates J of the chain-stoppers J upon the anchor-chains, in order more effectually to stop the same.

When the chains are being paid out, the plates J are held up out of position by means of chains M, attached to the forecastledeck G, or any other suitable point.

The operation of my invention will be so readily understood it will be unnecessary for me further to describe the same.

Having thus described my invention, what I claim, and desire to secure by Letters Patent,

1. The combination, with a chain-stopper, J, of the'plate J provided with a notch or recess, j, and a pivoted lever, J provided with a cam-surface, J substantially as and for the purpose described.

2. The combination, with a chain-stopper, J, provided with a groove or channel, J and a pivoted locking-plate, J formed with a notch or recess, j, in its forward end, of the pivoted lever J provided with a camsurface, J substantially as and for the purpose specified.

3. A chain hawser-pipe, L, havinga groove or channel, I, for the purpose of guiding the alteinate links of the chain, substantially as In testimony that I claim the foregoing as and for the purpose described. my own I aflix my signature in presence of 4. The combination, with the anchor G and two witnesses.
