SUSPENSION TACKLE FOR BOATS.

Application filed remar 10, 1922. Serial No. 535,563.

TQflZZ whom it may concern.

Be it known that I, WALTER J. FARLEY, a citizen of the United States, and resident of Manitowoc, in the county of Manitowoc and State of Wisconsin, have invented certain new and useful Improvements in Suspension Tackles for Boats; and I do hereby declare that the following is a full, clear, and exact description thereof.

The invention relates to devices for safely landing men from a ship. I

It comprises a boom adapted to swing out wardly by force of gravity under the control of a man and a boatswain chair adapted to be manually controlled for the depositing of a passenger.

Important objects are the utilizing of the force of gravity to swing the boom outwardly, the movement being free and the only place of friction being at the pivot for the boom. Consequently, the chair may be drawn inwardly readily, the inward move ment being opposed solely by the force of gravity and the travel being along a slight incline.

An important feature is the provision of a boom which may be shifted from one side of the ship to another, only one guy llne being necessary though a plurality of clevises, in which the boom is pivoted, are provided. Thus passengers may be discharged from either side of the vessel.

Another advantage of the construction is the utilization of the structure of the ship to limit the outward movement of the pole in such a manner that its final position is substantially at right angles to the boat. The device is of such a nature that it may be readily stored out of the way when its functions are not required.

With the above and other objects in view, which will appear as the description proceeds, my invention resides in the novel construction, combination and arrangement of parts substantially as hereinafter described and more particularly defined by the appended claims, it being understood that such changes in the precise embodiment of the herein disclosed invention may be made as come within the scope of the claims.

In the accompanying drawing, I have illustrated one complete example of the physical embodiment of the present invention constructed according to the best mode I have so far devised for the practical application of the principles thereof, and in which Figure 1 is a side elevation of the invention in out-board position.

Figure 2 is a plan thereof.

The boom 10 is rotatable on pivot 11 by which it is secured to clevis 12 and at its other end is provided with eyes 13v and 14, guy cable 15 extending from eye 13 to eye 16. Pivot 11 is at an angle to the line of gravity and eye 16' is alined therewith so that boom 10 will swing outwardly, gradually descending in its travel, guy cable 15 not operating to exert a lifting action on the end of the boom.

From eye 14 block 17 is suspended from which a rope 18 secured to eye 19 extends downwardly and is roved through block 20 and directed upwardly through block 17 and then extends to the deck where it is adapted to be controlled by an operator for the raising or lowering of a passenger in boatswain chair 21 secured to block 20. A pair of oppositely disposed eyes 22 and 22' are secured to boom 10 intermediate its ends and a guy line 23 is detachably secured to eye 22 by hook 24.

When the device is used in landing, a passenger is positioned in boatswain chair 21 when the boom is in in-board position, a man tensioning rope 18 and being enabled by the disposition of the blocks 17 and 20 to sustain the weight of the occupant of the chair. The weight of the passenger tends to swing boom 10 outwardly under the control of an operator manipulating guy line 23. Deck house 25 operates, as shown in Figure 2, to limit the rotary movement of boom 10 so that its final position is as shown, substantially at right angles to the side of the vessel.

If it is desired to use the boom on the other side of the ship, pivot 11 may be removed and the boom placed in a clevis provided for the reception of boom 11 and hook 24 may be secured to eye 22. Thus, in order to discharge passengers from both sides, a duplication of the elements is unnecessary.

It will be apparent that considerable looseness of parts may be provided at the pivotal point of the boom for facilitating the movement of the boom to various positions.

I claim 1. The combination of a boom, a pivot therefor inward of the gunwale of the ship, a guy cable secured to said boom and fixed ment thereof, means secured to the outer end of said boom for landing a load, and means for limiting the movement of said boom to an out-Ward position substantially at right ngl t said hip-v a In testimony that I claim the foregoing I have hereunto set my hand at Manitowoc, in the county of Manitowoc and State of lVisconSin.
