BRAKE FOR MARINE VESSELS.

To all whom it may concern:

Be it known that I, EMIL E. KoL'rKo, a citizen of the United States, residing at VVaterbury, in the county of New Haven and State of Connecticut, have invented new and useful Improvements in Brakes for Marine Vessels, of which the following is a specification. 1

This invention relates to brakes for marine vessels, the object in view being to provide in connection with a pair of movable braking wings moimted on opposite sides of the vessel and adapted to turn on substantially vertical axes, simple and effective mechanism "whereby the said braking wings may be operated either to release the same and permit them to open to their operative position, or to draw the same inward to their housed or folded position.

A further object of the invention is to provide novel and eflicient means for looking said wings in their folded or inoperative positions, combined with means for tripping the locking device when it is desired to release said wings and permit them to assume their working positions.

With the above and other objects in view,

the invention consists in the novel construction,- combination and arrangement of parts, as will hereinafter be more fully described, illustrated and claimed. Q I

In the accompanying drawings :Figure 1 is a plan view of the forward portion of a marine vessel showing the mechanism of this invention applied thereto. Fig. 2 is a side elevation of the same. Fig. 3 is an inside face view of one of the wings. Fig. 4L is a detail perspective view of the keeper bar or locking device.

Referring to the drawings, 1 designates a portion of the hull of a marine vessel, the same being shown in plan view in Fig. 1 and in side elevation in Fig. 2.

In carrying out this invention I provide a pair of wings 2 located at opposite sides of the bow of the vessel and extending any suitable distance belowthe water line, the said wings being jointed at their rearedges as shown at 3 to the hull of the vessel so that said wings may swing outwardly and inwardly on substantially vertical axes. At their forward extremities the wings 2 are deflected outwardly or provided with flanges t which are adapted to lie in parallel relation to the opposite sides of the forward stem 5 of the vessel. so as to be Specification of Letters Patent.

engaged by a keeper bar 6 which is substantially U -Shaped in cross section so as to embrace and hold both of the flanges 4 of the wings when the latter are folded inwardly. The keeper bar 6 is arranged in a substantially vertical plane and is pivotally mounted intermediate its ends at 7 on a suitable bracket 8 shown for convenience as fastened to the deck of the vessel. The keeper bar 6 by reason of its shape is adapted to simultaneously embrace and hold both flanges 1 and in addition thereto said keeper bar is provided with a plurality of sets of rearwardly diverging fingers 9 adapted to bear against the outer surfaces of the wings 2 to serve as an additional safeguard against the accidental outward mcvement of said wings.

The wings 2 are provided at their rear edges with inwardly extending arms 10 which cross or intersect each other as shown in Fig. 1, the inner ends of said arms being arranged in front of a trip lever 11 which is fulcrumed about centrally at 12 on a supporting bracket 13 also shown as secured to The lower arm of the lever 11 is adapted tocoiiperate with the arms 10 for the purpose of thrusting the arms 10 in a forward direction to start the leading edges of the wings 2 outwardly. The lever 11 is operated by means of a chain 14 one end of which is connected to the upper extremity of the keeper bar 6 at the point 15 while the other end of said chain is wound upon one section 16 of a double windlass designated generally by the reference character A. This Windlass is adapted to be operated by any suitable power, either hand power or engine power as may be preferred. The chain 14 is primarily used to operate the keeper bar 6 so as to swing the same forward to the dotted line position shown in Fig. 2 for the purpose of releasing the leading edges of the wings. In order to operate the lever 11, a stop or lug 17 is fastened on the chain 1 1 and adapted to come in contact the wings. Therefore, when the sec of the windlass is revolved in one .LlUll, the keeper bar 6 is first operated and subsequently thereto the lever 11 is actuated to trip the wings by means of the arms 10. As soon as'the wings start outwardly, they are caught by the rush of water past the sides of the vessel and moved outwardly to their limit. Around another section 18 of the windlass A are wound chains or cables 22 which extend in opposite directions around guide pulleys 23, said cables or chains being terminally connected at 944: to bridles 25 on the inner faces of the wings 2 as illustrated in Fig. The chains 22 are used primarily to draw the wings 2 back against the hull of the vessel after the latter has come to a standstill and they may also serve as means for limiting the outward movement of the wings and staying said wings when they reach. their outer limit of movement.

As illustrated in Fig. 2, the wings 2 may be provided with port holes 26 to register with the port holes 27 in the vessel when the wings are folded against the sides of the vessel. 28 designates a guide pulley around. which the chain 14 passes. Channels or gutters 29 and 30 are preferably used to form run-ways for the

chains

19 and 22 and if desired these run-ways may be in the form of pipes or tubes.

From the foregoing description it will now be understood that by dperating the chain and windlass mechanism, the keeper bar 6 is first thrown out of locking position and afterward by the cooperation of the lever 11 and the arms 10, the leading edges of the braking wings are started outwardly after which they are thrust to the full limit of their outward i'i'iovement by the action of the water thereon. The parts are restored to their folded posit-ions also by means of the chain and windlass mechanism, the windlass section 1.8 being first operated to draw the wings back to their folded position, after which the windlass section 16 is operated and acts first to restore the trip lever 11 to its normal. position and subsequently to restore the keeper bar (3 to its wing-locking position.

The brake hereinabove described will bring the vessel to a standstill in a very short distance and avoid many of the accidents which so frequently occur by reason of the inability of the engines to check the forwardmovement of the vessel in time to avert such accidents.

What I claim is 1. The combination with a marine vessel, of brake mechanism comprising a pair of wings pivotally mounted at their rear edges to turn on substantially vertical axes, the forward edges of said wings lying on opposite sides of the front stem of the vessel and being adapted to swing outwardly away from said stem, a substantially vertical keeper bar pivotally supported intermediate its ears and adapted in one position to embrace the leading edges of said wings when folded inwardly, and windlass and chain mechanism connected with said keeper bar for moving said bar to wing-engaging and disengaging position.

2. The combination with a marine vessel, of brake mechanism comprising a pair of wings pivotally mounted at their rear edges to turn on substantially vertical axes, the forward edges of said wings lying on oppo site sides of the front stem of the vessel and being adapted to swing outwardly away from said stem, a substantially vertical keeper bar pivotally supported intermediate its ends and adapted in one position to embrace the leading edges of said wings when folded inwardly, and windlass and chain mechanism connected with said keeper bar both above and below the pivot thereof, for moving said bar to wing-engaging and disengaging posit-ion.

3. The combination with a marine vessel, of brake mechanism comprising a pair of wings pivotally mounted at their rear edges to turn on substantially vertical axes, the forward edges of said wings lying on opposite sides of the front stem of the vessel and being-adapted to swing outwardly away from said stem, a substantially vertical keeper bar pivotally supported intermediate its ends and adapted in one position to embrace the leading edges of said wings when folded inwardly, windlass and chain mechanism connected with said keeper bar for moving said bar to wing-engaging and disengaging position, and set-s of wingholding fingers on said bar.

t. The combination with a marine vessel, of brake mechanism comprising a pair of wings pivotally mounted at their rear edges to turn on substantially vertical axes, the forward edges of said wings lying on opposite sides of the front stem of the vessel and being adapted to swing outwardly away from said stem, a substantially vertical keeper bar pivotally supported intermediate its ends and adapted in one position to embrace the leading edges of said wings when folded inwardly, and windlass and chain mechanism connected with said keeper bar for moving said bar to wing engaging and disengaging position, arms extending inwardly from said wings, and a trip lever acting upon said arms to start the wings outwardly and acted upon by said windlass and chain mechanism.

5. The combination with a marine vessel, of'brake mechanism comprising a pair of wings pivotally mounted at their rear edges to turn on substantially vertical axes, the forward edges of said wings lying on opposite sides of the front stem of the Vessel and being adapted to swing outwardly away from said stem, a substantially vertical keeper bar pivotally supported intermediate its ends and adapted in one position toembrace the leading edges of said wings when folded inwardly, Windlass and chain mechanism connected with said keeper bar for moving said bar to wing-engaging and disengaging position, bridles on the inner faces of said wings, 10 and Windlass and chain mechanism connected with said bridles.

In testimony whereof I aflix my signature in presence of two witnesses.
