Be it known that I, FRIEDRICH WENDLER, acitizen of the United States,residing at New York, in the borough'of Brooklyn and State of New York, have invented certain new and useful Improvements in Drag-Brakes forMarine Vessels, of which the following is a speci' ication. v l p The p resent invention relates to a dragbrake for marine vessels; and its object is to" provide a simple, convenient', and eiiicient means for instantaneously applying the brake by dropping it astern the vessel `behind the propeller.
The invention consists in a scoop-like drag whichis connected with each side ofthe stern of a vessel by means of pivoted links'or arms, and is provided with Suitable raising and lowering means,so that the drag can be swung .'JO.
up onto the doek when out of use or be permitted tolswing down aft of thevessel by `its own weight,as will be hereinafter described in A detail and then particularized in the claims.
In the accompanyingdrawings, Figure lis an elevation of the port side of a vessel, showing my improvement.. Fig. 2 is an enlarged n side viewparts being insection, of the stern v`of a vessel, showing my improvement in po-` sition of rest.
Fig.` 3 is a similar side view showing the drag in lowered using position,
andFig. 4 is a perspective detail of the drag and its arms or links.
Similar letters of reference indi-cate corre-` i spending parts.
Referring to the drawings,\A indicates a vessel provided with a raisedstern-seat B on which the helmsman may sit, while below the seat, on the deck of the vessel, is iixed a pair of side cheeks or guides b,only one of which is shown, the other on the starboard side be- Gnided upon and resting onl ing apparent. the guidecheeks 7J is a scoop-shaped drag C, which is provided at each side with rigid arms or linl-:s D, that are pivoted at d to the opposite sides of the stern of the vessel A, the
pivots being preferably applied to metallic` The sides ofI the drag G are formed with guide `grooves or side strips orcleats, such as e.
ways C', so as `to `facilitate upon the cheeks l).
its being gulided The drag is operated by `means of a wind lassl l?, mounted in suitablefbrackets g` on the deck of the vessel, said windlass being connected by means of a rope or cable f, which passes through an openingpb' in the riser of the' seat, with an eye f at the `back of the drag, said windlass being turned by means of a hand-wheel H, so as to wind the rope f upon it and to raise or lower the drag.V The shaft of the 'Windlass carries a ratchet-wheel 7i, which is engaged bythe tooth'h' of a pivoted handle-ver h2, arranged in front of seat B.
i `The downward movement of the drag is liinitedby means of a limit rope or cable i', so that the drag will sink into the water just behind the propeller j.
4 The operation is as follows: When out of use, the drag is supportedout ofA sight upon the guide b under the seat B, and the cable or rope f imwound tightly upon lthe windlass, the parts being retained in position shown in Fig. 2 by the toothedhand-'lever h2 and ratchet-wheel h. If the vessel is to be suddenly stopped,the helmsman grasps the handlever h2 and disengages it from the ratchetwheel 71., so that the weight of the drag will cause it to drop immediately aft in braking position, and in doing so to unwind the rope or cable f from the windlass. limiting'rope or cable provided so that the shock from the release and falling of the `drag will not injure the windlass, else the, rope f could be used to limit the downward movement of the drag. lThe braking action or resistance furnished by the drag and the .-actionof the propeller (if it has not been itself stopped) in throwing the water against the drag nowbring the vessel quickly to a standstill. The dragcan now be shipped by the helmsman 'by turning thc hand-wheel of the windlass and winding up therope or cable f until the drag rests in normal position under the seat B and upon the guide therefor.
The drag-brake described is comparatively simple and may be quickly applied, so as to stop the vessel provided therewith.
Having thus described my invention, I claim as new and desire to secure by Letters Patentb I l. The combination, with av marine vessel, of a swinging sccop-like drag-brake extending transversely across the stern, and means for raising and lowering the said dragbrake, substantially as set forth.
