This invention relates to an .anchor ofthe*- folding fluketype in whichL mea-ns is 'provided' for holding 'the flukes in their folded v and Yunfoldedpositions. n i I One of the objects is to pivot the ilukes to thesupporting stem to swing in planes at l "substantially right angles to `each other so as i 2"k pling element.

i `A further object is to taper theheelsof the flukes in such manner that contiguous lsides of the tapers Aof adjacent flukes may yform cooperative stops for limiting the opening movement of the flukes.

A further object is to provide the supporting stem and locking'collar with cooperative cam faces whereby .the fiukes may be held in their folded andunfolded positions 0,by a simple turning movement vofthe collar `relatively to the stem. .Otherv objects and uses relating to specific parts of the device will be brought 'outin the following description.

fAs illustrated, this anchor" comprises a ing andsupporting theiinner ends lof the,

` with an rin any well-'known manner 'for producing main supporting stem"'-1-, a plurality of, in this instance four, folding iiukes4-2 and a locking collar 3 slidable lengthwiseof and upon the stern -1 to cooper ate with said stem for `holding the vflukes in their folded and unfolded positions.

.The lower end of the steni1-` is provided with a substantially fiat lower face -4 and a plurality of, in this instance y four, outwardly projecting apertured lugs"5 -5 arranged in uniformly spaced relation circumferentially and, therefore, at'substantially right angles `to each other forreceivfiukes y The upper end 4of the stein isprovided v eye -6- for receivingone end of'a rope, chain or other suitable'cable havingfits other endl attached to the boat or other float. y`

the desired connection between the float and anchor.% .i

The major portion of` the length. of the stem 1 betweenthe lugs---` and eve 6- is substantially straightbut prefer-y vably corrugated transversely for strength,

the corrugations consistingofa pluralityof, 1n this instance four, lengthwise ribs b-'6- and -64 arranged in uniformly spaced re# lation about the axis of the stemfand preferably in vertical alinement with the ,lugs -5-, said ribs being preferably of uniform lradial widththroughout the major portions of their lengths to permit the col-l lar n-3- to slide and turn freely thereon when adjusting it from one extreme to its other extreme locking position. The lower ends of two ofthe diametrically opposite ribs 6-. are slightly enlarged or widened to form shoulders -8- whichv 95 are arranged in axially, spaced relation to the corresponding lugs -5, to form re.` cesses -9-, said shoulders being .adaptedto be engagedy by the cam faces of the collar -S-f for holding the flulres -2-in their 190 open or unfolded positions in a manner presently described.

The upper portions of two of the diamet` krically opposite ribs -6- are also enlarged or widened to form shoulders 10 in 105 axially spaced relation to the shoulders l -8- a distance slightly greater than the distance between thev pivots of the flukes `-2 and free ends of the `flukes andv adapted to be engaged by the cam face of 110V the collar -53- for locking the flukes in their closed or folded positions as shown in Figures l and 2.

The upper ends of the ribs -6- and -G are connected by an annular bearing -lljust below the shoulders 10;- and against which the free ends of the flnlies are adapted to rest when locked in their folded positions. r

The fiultes -2-- are coneavo-convex longitudinally froiu end te end and are arranged in uniformly spared relation cirouniferentially aboi'it the anis of the stein -1- in alineinent with their respective lugs 5-, the opposite longitudinal edges of each iiule heine substantially straight and parallel throughout the major portion of its length.

Each fluke is provided near its lower or inner end with iair of inwardly or upwardly projecting -lQ- in transversely spaced relation corresponding to the thickness of the lugs so as to engage opposite faces thereof and to which they are pivoted by pivotal bolts i3- Y The lower or inner end of each fluke Q- is tapered or beveled at llat an angle of substantially degrees to its longitudinal center and projects downwardly or in` wardly beyond their pivots l2- a distance corresponding' approxiiratelj,Iv to the distance between said pivots and the axis of the stein -lthat when the linkes are unfolded to the position shown by dotted lines in Figure Q and b v full lines in Figure 3, the contiguous beveled eoees of adjacent fiules will abut againfft each other below the lower end of the stein -las shown in Figure 5 to limit their opening; or unfolding movements in such manner that the fiukes will lie in the arcs of a spherical segment as shown by dotted lines in Fiejure 2.

Under these conditions the lower surfaces of the flukes across the lower end of the stem will be snbstantiall)v smooth and continuous permittingthe entire weie'ht of the anchor to be thrown upon the points of two or more of the fiukes when dragged upon the water bed or through other obstructions duringl which operation the two engaging; flukes will have a ,side draft from the points toward the centerwith the transversely fiat inner faces presented their full widths at an angle to the bed for greater resistance to draft when anchored in said bed.

The collar -3- is preferabli7 made in the form of an inverted cup or concavoconvex in cross section and is provided with a central opening 15H and diametrically opposite grooves -16- leadingr laterally from the central opening` which of sufficient di-i ameter to permit the collar to slide freelyi alone the main bony of the stein 1 but is of less diameter than the width of the except at the grooves -lG- which are slightly wider than the shoulders Sw and -lO- to permit the collar to pass over said shoulders when the grooves or recesses 1G-- are alined therewith.

On the other hand. when the collar turned so as to bring the groove -iG- out of registration with the shoulders and -l0- the latter will serve to retain the collar against axial displacement from the stein7 it beinl understood that the outer diameter of the eye -G is sulliciently small to permit the collar to be removed from the upper end of the stein when the recesses *16- a 'e registered with the shoulders -10-.

The upper end of the collar --lis provided with an annular iiange having end cain faces -17- between the grooves 1G- to engage the shoulders -S- and l0- for lockingthe iii-lilies in their open or unfolded positions as shown in Fie/'ure or in their folded positions as shown in Figure :2.

Operation.

For example, when the {lultes are folded with their free ends resting; against the annular bearing' -llas shown in Fienres l and 2, the collar 3W is moved dov-inwardly to surround the upper endif-f. of `the. linkes after which the collar .may he turned slightlyv in the proper direction to cause its cani faces 17- to engage the shorn- Jo-- and thereby to loci; the collar against the upper ends of the Afolded linkes for holding` the latter in their closed positions.

The turningl of the collar in a reverse direction to register its (groove -lG- with the shoulders 10W permits .said collar to be raised sutliciently to release the tlukes whereupon the latter drop by their own weight until the contiguous beveled edees of their inner ends engage each other whereupon the collar may be moved downwardly alone` the stem -lso that its upper end registers with the recesses -9- and then by turning the collar in the proper direction will brine' its cani faces -l7 into engaeement with the shoulders -S- while the lower marginal flanges of the collar will rest against the adjacent portions of the upper faces of the tlules to hold said linkes in their open positions followingl which the anchor is ready for use.

It will he observed that the outer ends of the foldingr fluhes are also tapered to form digging` points and thereby to facilitate the entrance of the lluhes into the water bed.

It will also be noted that the collar -3- is provided with laterally proiecting wines the collar about the axis of the stein.
