BOAT-ANCHOR HGIST.

Application filed June 11, 1925.

Our invention has tor its object to provide a boat anchor hoist and to this endi it coir sists of the novel devices and combinations of devices hereinafter described and defined in the claims.

in the accompanying drawings which illustrate the invention, like characters indicate like parts throughout the several views.

Referring to the drawings:

Fig. 1 is a view of a row boat having the invention applied thereto and resting on a body of water;

Fig. 2 is a plan view of a boat and hoist;

Fig. 3 is a detail view principally in vertical section, taken on the line 33 of 1, on an enlarged scale;

Fig. 41 is a view partly in inside elevation and partly in vertical section, taken on the irregular line 4l-4i of Fig. 3

Fig. 5 is a perspective view ot' the hoist attaching bracket;

Fig. 6 is a detail view prineipall y in trans verse section, taken on the line 6-6 of Fig.

Fig. 7 is a fragmentary detail View prin cipally in section, taken on the line 7-7 of Fig. 4t; and

Fig. 8 is a perspective view showing an other form of a hoist attaching bracket.

The numeral 9 indicates a body of water on which is resting a row'boat 10 having the invention applied thereto.

The numeral 11 indicates an anchor in the form of a weight resting on the bottom of th body of water and holding the boat, and to which anchor is attached one end of a hoisting rope 12. The other end of the hoisting rope 12 is attached to and arranged to be wound upon a windlass drum 13 having at its ends disc-like heads 1st. This windlass drum 13 is loosely journaled on a spindle 15 carried by a hoist-attaching bracket 16 applicable to the gunwale of the boat 10. Said attaching bracket 16 comprises a pair of horizontally spaced bars 17 rigidly connected by a pair of yokes 18 arranged to span the gunwale of the boat 10 with said bars on opposite sides thereof, as best shown in Fig. 3. The attaching bracket 16 also includes a pair of thumb screws 19 having screw-threaded engagement with the inner bracket bar 17 and arranged to impinge against the gunwale of the boat 10 and clamp the outer bracket bar 17 thereagainst.

The spindle 15 on which the windlass drum 13 is journaled is attached to the inner bracket Serial No. 36,436.

bar 17 and projects horizontally inward theretrom. Said Windlass drum 13 is held on the spindle 15 by a washer 20 and a cotter pin 21 inserted through a bore in said spindle. A hand crank 22. for operating the Windlass drum 13, is attached to the inner head 14- of said Windlass drum.

To prevent backward rotation of the windlass drum 13, which would unwind the hoisting rope 12 therefrom, there is provided a ratchet wheel 23 carried by the outer end of said Windlass drum and a co-operating gravity-actuated pawl 21 pivoted at 25 to the inner bracket bar 17. The movement of the Windlass drum 13 is controlled during the unwinding of the twisting rope 12 therefrom by a brake drum 26 and co-operating brake band 27. Said brake drum 26 is interposed between the. ratchet wheel 23 and the adjacent windlass drum head 1-1 which, together with said ratchet wheel, are rigidly secured to the windlass drum 13 by a plurality of screws 28. The ends of the brake band 27 are pivotally attached to a brake lever 29 at diametrically opposite sides of its fulcrum 30 which intermediately secures said lever to the inner bracket bar 17.

Formed with the rear end of the pawl 24 is a tripping lug 31 arranged to be engaged by the brake lever 29 during the brake-setting action to lift the pawl 24 out of engagement with the ratchet wheel 23 and thereby permit the movement of the windlass drum 13 during the unwinding oi the hoisting rope 12 therefrom to be controlled by the brake band 27 and co-operating brake drum 26. Vi hen the brake lever 29 is moved to release the brake band 27 from the brake drum 26 the pawl 2 1 will, at the same time, be released from the brake lever and automatically re-engage the ratchet wheel 23.

As illustrated in the drawings, the hoisting rope 12 is arranged to run over a guide sheave 32 at the prow of the boat 10 and is also arranged to run over a plurality of guide sheaves 83 secured to the gunwale of the boat 10 between the windlass drum 13 and guide sheave 32.

Obviously, the attaching bracket 17 may be secured to the gunwale of the boat 10 at any desired point so that the windlass drum 13 may be operated by an occupant of the boat when sitting on any one of the seats thereof to raise or lower the anchor 11. As the Windlass drum 13 is mounted so as to extend into the boat 10 the said anchor may be easily lowered and the movement thereof controlled by manipulating the brake lever 29. By operating the crank 22 the anchor 11 may be quickly raised and held raised outside of the boat 10 by the ratchet wheel 23 and co-operating pawl 24:. From the above description it is evident that the anchor 11 may be raised and lowered without danger of tipping the boat, Without getting any water in the boat and with very little effort on the part of the operator, and without having to stand up or change his seat. Furthermore, the anchor hoist may be very quickly attached to a boat and removed therefrom.

Referring now to the modification shown in Fi 8, there is illustrated an attaching bracket 34 in the "form of a flat bar having in its lower edge notches 35 adapted to receive thumb nut-equipped bolts secured in the gunwale of a boat for clamping said bracket thereon. A spindle 36 is secured to the bracket 34 for a- Windlass drum.

lVhat we claim is:

1. A boat anchor hoist comprising a bracket applicable to a boat, a Windlass drum journaled on the bracket, a hoisting rope arranged to he wound on the Windlass drum, an anchor attached to the hoisting rope, a ratchet wheel, on the b 'ake drum and a Jew] on the bracket, a manually operated rake for the windlass drum imlependently mounted in respect to the pawl and having a part arranged to engage the pawl and re lease the same from the ratchet wheel during the brake-setting action, said pawl being arranged to automatically reengage the ratchet wheel during the releasing oi? the brake.

2. A boat anchor hoist comprising a bracket applicable to the gunwale ot' a boat and having an inwardly projecting spindle, a hand-crank-equipped windlass drum journaled on the spindle and having on its ends disc-like heads, a hoisting rope arranged to be wound on the Windlass drum, an anchor attached to the hoisting rope, a brake drum on the Windlass drum, a brake lever intermediately fulcrumed to the bracket, a brake band applied to the brake drum and having its ends pivoted to the brake lever at diametrically opposite sides 01 its fulcram, a ratchet wheel on the bake drum, a pawl pivoted to the bracket for eo-operation with the ratchet wheel, and a tripping lug on the pawl arranged to be engaged by the brake lever during the brake-setting action to release the pawl from the ratchet wheel.

8. The structure defined in claim :2 in which said pawl is arranged to automatically reengage the ratchet wheel when released by the brake lever.

4:. A boat anchor hoist comprising a bracket applicable to the gunwale of a boat and having an inwardly projecting spindle, a hand-crank-equipped windlase drum journaled on the spindle and having on its ends disclike heads, a hoisting rope arranged to be wound on the Windlass drum, an anchor attached to the hoisting rope, a brake drum on the Windlass drum at its outer head, a ratchet wheel on the outer end of the brake drum, a brake lever intermediatcly lulcrumed to the bracket, a brake band applied to the brake drum and having its ends pivoted to the brakelever at diamct rically opposite sides ol' its Yule-rum, said brake hand being held by the ratchet wheel and adjacent head of the Windlass: drum against axial drifting movement, and a pawl pivoted to the bracket for cooperation with the ratchet wheel and a tripping lug on the pawl arranged to be engaged by the l.)l':ll{l lever during the brake-setting action to release the pawl from the ratchet wheel, said pawl being arranged to automatically reengage the ratchet wheel when released by the brake lever.

In testimony whereof we allix our signatures.
