ingAnchors, or" which the lollowing'is a spccif iieation.'

My invention consists of improvements in that class ofanehors known as non-fouling anchors7 and in which all projections-such,

as the stock or the unused arm or fluke of ordinary anchors, by" which the cable can lonl in swinging, or upon which a vessel can be in'- jnred when in Y shallow `\\'ater-ar'c 'dispensed with, the flakes being pivoted vand arranged to. lie Within the shank' enti rely ont of the'way when not in use. A

Saigdimp'rovexnents relate to the combina'- tion of a pivoted oatchwith the pivoted iluke of a nonfouliig anchor, to sulserve the .sn-me end asthehornupon the llukeefan ordinary anchonand operate to prevent the palm from dragging over the ground by causing itto take hold thereof, the end' attained by the stoel: of an ordinary anchor'.

Figurel of the' accompanying drawings is a plan view'of :ny improved non-fouling` anchor hung` up by a ring at the bottom thereof 5 Fig. 2, a central longitudinal section thereof in the line r of Fig. 1; Fig. 3, la side elevation ofthe anchor bent to a cable byits uppervring and en- Figs. 4 and 5 a-r'c detachedv views, illustrating` dif ferent torins of my swinging` catches; lfig, Ai, a detached viewofthe'tlnke, illustratin nl` cathes combined laterallytherewith.

` A is the shank orbody ol' niy improved an-l b an'interinediate open space, E, being lett to;

inclose a pivoted fluke. The shanlert is en'- largedor widened centrally in such 'manner as'to fmrm` projections B Bon either side or edgethereof, extending so far as to prevent 4theanehor from resting upon either vside or edge when thrownout, and insure itsV falling or turning` upon oncfof. the faces through which the pivoted iinke' swings.

, The opening E toreeeire the fluke may be l strain:

made to 'conform with the outward configura- I tion ofthe steek, thereby leaving space for a r 'wide dlaniondshaped palm upon the `fluke, ns A illustrated in the drawings, Figs. l and 6.'

(l is the linke ofthe anchor, pivoted, in the usual manner, inthe sha-nk A, so as tos`wing .freely in either direction' through the opening' therein.- v

D 'is the pivot upon which the llnke s 'ings'. its movements are arrested (see Fig. S) hy suitable shoulders, c c, Fig. 2, on the lower end thereof, which strike against the-lower end of the opening or slot ll in the shank.

F isa slot eut inthe linke C, within'which is pivotcd a pointed catch, thin such manner as that it may. suing; ont in either direction to about'an angle el' ibriylive (kleines,l when its further movement is arrested hysnitablestops, or in the manner-imlieated respect ing the linke (l. 'lhc catch. ti may 'he provided-wth.une@ two, or more points, as illust rated in the drawf ings. f

H' ll, Figs. 6 and 7, are eatehespivoted upon the sides of the lulze C and which are' freeto vibrate or swing` outward either in both directions, or else the one to the right andy the other' to 4the le't unt-il they attain an angle of about forty-tive degrees with the linke, when they are arrested from further movement in thatdireetion by suitable stops, as in the case of the catches l( is a bolt or pin inserted through a suitaf ble aperture in the shauk'granelintothe'ilulte C, to lock the same when -the anchor is not in use. This holt maybe secured hy a lanyard to the chainsor rail from whence the anchor is hung, to be ready l'or use. Then my improved anchor is thrown out, ,the peeuliardiamdnd torni of the shank causes it to fall orturn'with one ot' its faces to the ground, so that the lluke' will rest thereon. ln this position one ofthe points'otthe eatelr G will be forced into the ground, and, so soon as there is a strain upon the anchor draining;v

it tbrward, thelluke will- 'he thereby tripped, so that its point willbe forced intothe ground, and a hold thus surely and immediatelyob'- tained, obiv'iating the v.danger and risleol' a dragging of, the anchor overk and upon 'the 'ground ou hard bot-toms, incident. to anchors without horns. So soon as the fluke engages Ywith the betteln the catch is relieved from all vWhen not required in use, the anchor may' be fished or catted and hung,` up by its lower ring. (See Fig. l.) Its linke C und the catch G will then lie parallel to the shank, so that the anchor is at once compnet and ready for service, presenting no projections which can injure the bows. of the vessel; or itnnny be looked with the beltA l undy stowed in the chains or inbonrd with great convenience. If.- is peculiarly adapted for use upon 'vessels ol Win', not only because ol the ireinty with which itinziybe stowed away :unl protected from exposure to nn eneinys sheilwbut because, from its compact fmnx, Ltr-.ill noi; break in the and splinter u'hen struck by zishoi, z, ease of ordinary anchors.
