DAVIT-SUPPORTING MEANS FOR SHARP-STERN BOATS.

Application filed. February 10, 1908.

To all whom it may concern:

Be it known that I, JOSEPH EDWARD ROB- BINS, a citizen of the United States, residing at Cambridge, in the county of Dorchester and State of Maryland, have invented certain new and useful Improvements in Davit- Supporting Means for Sharp-Stern Boats, of which the following is a specification, reference being had therein to the accompanying drawing.

My invention relates to improvements in davit supporting means for sharp stern boats.

The object of my invention is to provide a supporting means whereby the davits may be arranged at the stern of a sharp stern vessel for supporting the yawl boat, which has not been accomplished in boats of this character.

Another object of my invention is to provide a more simple, cheap and effective supporting means for accomplishing the above results.

In the accompanying drawings, Figure 1, is a top plan view of a sharp stern boat showing my davits attached thereto. Fig. 2, is a side elevation of Fig. 1, and Fig. 3, is an enlarged sectional view showing the connection of the davits with the deck of the vessel.

Referring now to the drawings, 1 represents the sharp stern of a vessel, which is provided with the usual gunwale 2, and it will be seen that it is impossible to secure davits directly to said sharp stern to support the yawl boat out beyond the stern of the boat. In order to be able to support the davits at the sharp stern of the vessel, as in broad stern vessels, I provide my improved frame whereby the davits may be secured and the yawl boat supported in the same manner as in a broad stern boat.

The reference numerals 3 and 4 represent two parallel beams which are secured to the outside of the gunwale of the boat, as indicated at 5. The said beams extend rearwardly and upwardly, and have secured on their upper faces at their outer ends a transverse beam 6 which extends across the sharp stern resting thereupon, thus aiding in supporting the beams in the position shown in Fig. 2. The beam 6 is further braced and secured to the beams 3 and 4 by angle irons or wooden brackets 7 and 8, thus preventing any twisting of any of the beams. The transverse beam 6 may or may not be secured to the sharp stern of the boat. Secured to the inside of the gunwale of the boat adjacent the point where the beams 3 Specification of Letters Patent.

and 4 are secured are brackets 9 through which the davits 10 and 11 pass. The deck 12 below said brackets is provided with sockets 13 in which are secured the lower end of the davits. The said davits, as shown extend upwardly at 14 and are bent outwardly at 15, having the outwardly and upwardly inclined portions 16 and 17 parallel with the beams 3 and 4. The said portions 16 and 17 extend a considerable distance beyond the beams, and also a distance beyond the extreme end of the vessel.

The cross-beam 6 has at its end the upwardly-extending braces or brackets 18 and 19 which have their upper ends secured to the lower faces of the davits, and whereby the weight and strain on the davits is directly upon the said brackets, thus relieving the davits of the great strain that would otherwise be on them owing to their great length necessary to carry them beyond the end of the sharp stern.

Secured to the upper faces of the extreme outer ends of the davits is a transverse beam 20 made of wood, which further braces the davits and prevents any twisting etc. thereof. Secured either to the lower face of the outer end of said davit, or to the ower face of the beam 20 adjacent the davits are the eyebolts 21 into which are hooked or otherwise secured the blocks 22. The cables 23 pass over the blocks 22 and are detachablysecured to the yawl boat 24 in any desired manner. The inner end of the cables are fastened to cleats 25 carried by the gunwale or any other part of the vessel, or if desired, could be secured to davits.

By the construction herein set forth, it will be seen that applicant has produced a simple, cheap and effective means for attaching davits to sharp stern vessels, so that the yawl boat may be supported at the stern of the boat, the same as in broad stern vessels, and in which there is no undue strain upon the davits. Heretofore, in vessels of this character, it has been found almost impossible to support a yawl boat by means of davits, and it had to be held by davits at the side or carried upon the deck, both of which are in the way.

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

1. The combination with a sharp stern vessel, of a davit-support carried by the said sharp stern, and projecting beyond the sides thereof, and davits attached to the said support and extending rearwardly from the suppolrt, and beyond the sharp stern of the vesse 2. The combination with a sharp stern vessel, of a frame secured to the vessel and extending rearwardly beyond the sides of the vessel, a transverse beam forming a portion of the frame resting upon the upper face of the sharp stern, and davits supported by said frame and extending beyond the stern of the vessel.

3. The combination with a sharp stern vessel, of beams secured to the outside of the gunwale and extending rearwardly, a transverse beam connecting the outer ends of said beams and resting upon the stern of the vessel, and davits secured to the vessel and supported by the frame intermediate the ends.

4. The combination with a sharp stern vessel, of beams secured to the gunwale and extending rearwardly parallel with each other, a transverse beam connecting the outer ends of the said beams, and resting upon the stern of the vessel, davits having their inner ends secured to the vessel, and brackets carried by the transverse beam and connected to the davits intermediate their ends.

5. The combination with a sharp stern vessel, of beams connected to the gunwale and extending rearwardly parallel with each other, a transverse beam connecting the outer ends of the side beams and resting upon the stern of the vessel, davits having their inner ends connected to the vessel, a bar connecting the outer ends of the davits, and brackets carried by the transverse beam and extending upwardly and connected to the davits interme-; diate their ends.

6. The combination with a sharp stern vessel, of beams connected to the outside of the gunwale and extending rearwardly parallel with each other, a transv erse beam connecting the outer ends of said side beams and resting upon the stern of the vessel, davits having downwardly extending portions passing through brackets on the inside of the gunwale, and secured within sockets carried by the deck, said davits extending rearwardly parallel with the side beams, a beam connecting the outer end of said davits, and brackets carried by the transverse beam and extending upwardly and connected to the under side of the davits.

7. The combination with a sharp stern vessel, of beams secured to the vessel and extending rearwardly beyond the sides of the vessel, a transverse beam connecting the outer ends of said beams and resting upon the stern of the vessel, and davits supported by the side beams.

8. The combination with a sharp stern vessel, of beams secured to the vessel and extending rearwardly parallel with each other,

a transverse beam connecting the outer ends of the beams and resting upon the stern of the vessel, and davits supported by said beams.

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