Description
R. W. GIBB Dec. 15, 1931.
ANCHOR Filed March 21, 1931 Patented Dec. 15, 1931 UNITED STATES PATENT o1-FICE ROBERT W.'GIBB, 0F EAST DEDHAM, MASSACHUSETTS ANCHOR Application led. March 21, 1931. Serial No. 524,273.
Figure 1 a view of the anchor as it apy pears when in use with an ordinary knot in the anchor rope- Figure 2 is a top view of the anchor as it rests upon any flat surface with the weighted members folded togeth er without the attachment of the anchor rope- Figure 8 is a section at the line 3*?) of Figure 2 Figure 4t is a view similar to Figure 2 but withthe weighted members dropped down so as to assume a position parallel with the base- Figure 5 is a side elevation of the parts in the position shown at Figure 4, with rope attached in preferred manner, and Figure 6 is a view similar to Figure 2 but showing a slight modification of the base.
Similar numerals of reference denote like parts in the several figures of the drawings.
Part l. is the base of the mushroom type having rising from its center post 2 which terminates at its upper end in a stop 3 and is perforated as at 4 for the purpose presently to be explained.
The post 2 and the members 5 constitute the shank of the anchor.
The base preferably has openings 11 therethrough to facilitate the lowering Aand raising of the anchor.
"When the parts are in the position as shown at Figures 2 and 3, the perforations l0 will register', and it is possible to reeve an anchor 55 rope through these perforations and knot it in an ordinary manner and then throw the anchor overboard when it will assume the position shown at Figure l, the anchor rope being` designated by the numeral 12.
When the anchor is pulled inboard, the rope may be detached and the members 5 dropped down to the position seen at Figure 4, and the lugs 8 willV abut the post 2 and thereby prevent said members from contacting the base, thus doing away with rattling, and when the parts are in this position said members will be partly housed within the base and will be parallel therewith, thus pre- `senting a flat structure which may readily To 'be stowed away and not roll or rock.
The ball shaped assembled members 5 of the shank give the necessary weight so that when the anchor touches bottom it will be held on its side thusfacilitating its grip. Y 'T5 "If desired,'the perimeter of the base may have prongs 13 as shown at'Figure 6 to increase the grip of the anchor. There are no pins to insert, prongs to bend in place, or stock to adjust, but it is merely necessary to put a cable or rope through the perforations 10 when the Weight members are folded upwardly and knot such cable or rope, or to reeve such cable orrope through f said perforations while said members are dropped down and tie with a bowline, and as soon as said cable or rope becomes taut in the water all necessary adjustments are made. Also there are no arms, i'lukes, Shanks, or any i surfaces that would foul the cable or rope. U
The exterior' surfaces of the members 5 may be of any shape or contour, and the invention is not limited in this respect.
So far as the attachment of a rope or cable through the ears 9 of the sections 5 is concerned, my invention is not limited in this respect, and such rope or cable may be secured in any manner when the members 5 are lying flat as shown at Figure 5, and the in-` vention is not limited in this respect.
The attachment of the rope or cable to the members 9 by means of a bowline or by reeving such rope or cable through one ear 9 and tying a large knot 14 at the bottom so as to prevent slipping through the hole in such ear and then passing it downward to the other ear, as shown vat Figure .5, is preferable to thetying of the lrope tosaid earsvas shown at Figure l, since the anchor may always be stowed away without detaching the rope or cable.
That is claimed is i l. A mushroom anchor comprisng a flat cup-like base having rising from its central l5 portion a shank comprising a post, and a pair .of hemi-spherical memberspivoted to said post and perforated at their upper ends for -reeving of an anchor rope.
2. A construction as in claim l further distinguished in that said post has a stop against 'which said members abut when swung to elevated position.
3. A construction as in claim l still furtherfdistinguished in .that -w-hen the anchor is pulled inboard said members will drop dmvnwardly and be Ihoused within the base.
l. A mushroom anchorcomprising a flat cup-shaped base having ashank `consisting 'of an upright rising romits central portion 39 yandperforated at the top and havng a stop,
and a pair vof heavy members having flat vinner surfaces and suitably shaped outer sur- 'faoesj said members having holes at the top for thereeving of an anchor rope and abutting against said stop when closed and-capable of dropping within said base `and lying flat therein for vconvenient stowage.
A constructon as in claim A4f, with the addition that said members are provided with 7-9 stops at their inner ends which stops abut vagainst said upright7 whereby the members when opened do notcontact thebasethereby preventing rattling.
Intestimony whereof I affix mysignature -J hereto. l
