Description
G. P. EVANS ANCHOR DAVIT Dec. 8, 1953 2 Sheets-Sheet 1 Filed 001:. 26, 1951 Geo/- 2 1? Evans INVENTOR ATTORNEYS G. P. EVANS ANCHOR Dec. 8, 1953 DAVIT 2 Sheets-Sheet 2 Filed Oct. 26, 1951 extend beyond the edges of the pulley 24 to act as a guard to prevent the rope which is indicated by the reference character 25, and which passes thereover, from running off of the pulley when I the rope is operated to raise or lower the anchor which in the present showing is indicated by the reference character 26'.
Secured to one of the bars 23 of the outer section, is the rope jamb 21 which is formed of a length of strap metal bent upon itself providing a wedge-shaped opening 26, the rope jamb being bolted or otherwise secured to the outer section of the arm in such a way that it will overlie the space between the bars of the sections of the arm in direct line with the rope 25 which is used in connection with the davit.
It might be further stated that the supporting block I is provided with securing pins 28 which fit in openings formed in the davit base 5 so that the supporting block may be readily rei moved when desired.
From the foregoing it will be seen that due to the construction shown and described, I have provided an anchor davit which may be conveniently operated by a single person to raise or H of the rope to elevate the anchor or swing it to its inactive position on the deck of the ship, will result in the arm 8 being swung vertically over the deck of the ship without further movement of the rope over the pulley 24.
The chain 30 connects with the davit base 8 and arm 8, to regulate or restrict the vertical swinging movement of the arm beyond a predetermined point.
It will be noted that when the anchor has been properly located on the deck of the vessel, the arm 8 may be readily removed by removing the bolt iii, and the davit arm readily stowed where it will be out of the way.
By arranging the davit bases around the vessel at various locations, it will be obvious that the davit may be used or shifted from place to place to facilitate the handling of the anchor.
Having thus described the invention, what is claimed is:
'1. In an anchor davit, a base swivelled to the deck of a vessel, a davit arm pivotally connected to said base, said arm embodying an outer and inner section adjustable longitudinally with respect to each other, a pulley mounted at the outer end of the outer section, an anchor rope to which an anchor is secured, operating over thep-ulley, and a rope jamb mounted on the arm into which said rope is wedged connecting the rope directly to said arm for efiecting vertical swinging movement of the arm as said rope is pulled, and a chain secured between the base and arm limiting vertical swinging movement of said arm.
2. In an anchor davit, a base mounted on the deck of a vessel for horizontal swivel movement, a davit arm pivotally connected to said base for vertical swinging movement, a, pulley mounted at the outer end of the arm, an anchor rope operating over the pulley and to which an anchor is secured, a rope jamb mounted on the arm adjacent to said pulley into which said rope is removably wedged directly connecting the rope with the armthereby eifecting swinging movement of the arm when the rope is pulled, and a chain restricting vertical swinging movement of said arm.
3. In an anchor davit, a base, a davit arm pivotally mounted on said base and removably connected thereto, a pulley mounted at the outer end of said arm over which a rope operates and to which an anchor is secured, a member connected to said arm having a wedge-shaped opening into which the rope is wedged removably connecting the rope directly to said arm whereby vertical swinging movement is effected when the rope is pulled, and means for restricting vertical swinging movement of said arm.
4. In an anchor davit, a base swivelled to the deck of a vessel, a davit arm pivotally connected to said base, said base having a plurality of spaced openings formed therein, a block having a pin, adapted to be positioned in said openings adjusting and securing the block with respect to the base, said arm engaging said block restricte ing downward movement of said arn a pulley mounted at the outer end of the arm, a rope movable over said pulley and to which an anchor is connected, an open ended rope jamb secured to the arm adjacent to the pulley into which the rope is wedged securing the rope directly to the arm whereby vertical swinging movement of the arm is efiected when the rope is pulled, and means for restricting vertical swinging movement of said arm.
5. In an anchor davit, a base swivelled to the deck of a vessel, a davit arm comprising outer and inner sections adjustably connected for longitudinal adjustment with respect to each other lengthening and shortening said arm, a pulley mounted at the outer end of the arm, said pulley operating within the confines of the outer ends of said arm, an anchor rope movable over said pulley and to which an anchor is connected, a rope jamb secured to and extending upwardly from the upper surface of the arm, said rope adapted to be moved into said wedge jamb directly connecting the rope to the arm against movement with respect to said arm whereby vertical swinging movement of the arm is effected when the rope is pulled, and a chain connected between the arm and base adapted to limit vertical swinging movement of said arm.
