This inventionreiates to bollards or mooringposts and more particularly to bollards or jetty or the like, the improved bollardor mooring post accordin to the invention being, however, also applicable for use upon a ship, yacht or pontoon or the likei a The present invention has'among its jects to provide. an improved construction of bollard or mooring post whereby certain disadvantages dueto the ropes orliawsers slipping-up or down the post are ObVlEttSCl, and by the use of, which one or more'of the ropes or hawsers may be effectively secured with the minimum of turns.

VAccording to the invention a bollard or mooring post comprises verticallydisposed pillar or base'of-substantial cross section having at itsfupperpart a pair or-a plurality of upwardly extending splayedarms orposts, and having outwardly and rearwardly projecting parts aroundtwo angles of thebase and wat or adjacent the junction ofthelower ends of the respective arms or posts with the pillar or base, which projecting parts; are preferably somewhat "undercut or otherwise formed sothat their under-faces are'inclined downwardly fromlthe root to the extremity thereof; The pillar orbase and the arms or posts may be of any suitable cross-sectional shape and the laterally projecting parts may be also of any suitable shape, the bollardor mooring post being preferably in theiorm of I the term of a pair oi posts 6 which preferably divergeslightly upwardly away from one ana hollow casting integrallyprovided. with the arms or posts and with the laterally projecting parts. The pillar or base may be provided with a laterally extending flange at its lower end by which it may be bolted in position, and'ii desiredmay have a downward extension integrally or otherwise secured thereto, which extension is adapted to be embedded in the concrete or other material of which the dock is constructed, or to be bolted to additional supports at a lower level,

as when the bollard or mooring post isused reference to the accompanying drawings,

which v r V i Figure 1 1s a'rear elevation of a bollard or to Figure 1'; p v v g i Figure Bis a front elevation corresponding to Figures 1 and 2; i a ti Figure 4 is a corresponding vplan, anuthe invention, the bollard or mooringvpost coniprlsesx'a pillar or base a which isconvcni-ently hollow and of substantially rectangular Figure 5 is a section on the line5'5, Fig urel. .7. According to the illustrated embodiment of I laterallyeiitending flange 0;" at its lower end by which it may be bolted: to the docl: or the.

like or to the deck of a-ship orother foundatlon, and if necessary or desirable, may also be provided with a downwardly extending part a which may be integral with the pillar or base or; may be "constructed separately and bolted thereto, and whichis preferably in the form of a downwardly tapering hollow rectangular pillar. The downwardly extending part 2 may be provided at its lower end with a laterallv extending flange atby which it may be bolted to an additional support, or by so 7 which it may be'lzeycd into a concrete or other 4 foundation. 1

The pillar or basea iseictended upwardly in other, and may be of circular,v elliptical or other "suitable cross-section, for example, somewhat as' lndicated in Figures. Th-eupformed integral with the pillar or base a and jecting arms 0 which extend from positions at or adjacent the junction of the posts bwith the pillar or base a, the projecting arms 0 prefer bly diverging ontwardlyjfrom one another. The arms 0 may be of any sultable wardly extending posts I) are preferably, 7

the latter is provided with a pair of integral' t outwardly and substantially rearwardly protheprojecting arm 0, round the underface thereof, through the space between the posts in a comparatively sharp cornerat their junction with the under faces thereof, somewhat as indicated. in the drawings. The under faces of the arms c are practically inclined slightly downwardly from the root to the outer edge. as indicated at c in Figure 3, and adjacent their junction with the pillar or base a are curved and suitably shaped, as at 0 to accommodate a rope'or hawser.

The pillar or base a,-th e posts I) and the projecting arms 0 are preferably formed in one piece by casting and are preferably hollow as shown.-

It will be understood that by the use ofa bollard or mooring post according to the invention, it is immaterial whether the rope or hawser attached to the ship is substantially above or below the level of the. dock, inasmuch by carrying the rope or hawser beneath or above one of the arms 0 and around the respective post (2, the rope or hawser cannot slip'up or down upon the bollard or mooring post and is, moreover, very easily 'manipulated, as when checking and warping. For example, where the ship to which the rope or havser is attached is very high above the dock, the rope or hawser may be passed round the bollard as indicated on the left hand side of Figure 1, or alternatively, the rope or hawser may be passed downwardly from the ship underneath the left hand arm 0, through the space between the two posts Z), and around the rear of the right hand post 7), this arrangement being especially useful when checking or warping. Where the rope or hawser is attachei'to a ship be low the lev l of the docl-i, the rope or hawser may be disposed,-for example, as indicated on the right hand side of Figure 1, the rope or hawser being passed from the ship over,

' 6. round the rear of the respecti ve post I) and then back round the projecting arm 0 in the reverse direction. Alternatively, two

ships may be moored to the same bollard or mooring post by passing the looped ends of the mooring ropes through the space between the posts I) and round the projecting arms 0, somewhat as indicated in Figure 8. It will be appreciated that two separate mooring ropes or hawsers may be secured to the bollard without, however, jamming one upon the other so that the ropes or hawsers are 7 capable of being manipulated independently. The bollard or mooring post according to the invention is applicable for a variety of purposes. Thus, it may be employed on yachts where a vertical or horizontal lead is required, such as for the peakhalyards Itv will be notedthat it is unnecessary to take more than one complete turnof the rope around any part of the bollard, so that thus the formation of kinks in the ropeo'r h'a'wser may be avoided, and wear and tear thereon reduced and'the life of the rope accordingly increased with resultant economy.

It will be understood that the invention is not limited to the constr ction hereinbefore described. For example, the projecting arms 0 may be of any other suitable form, as in the form of thick rods projecting outwardly and rearwardly and somewhat downwardly from the junction of posts I) with the pillar 'or base a. "Furthermore, the bollard may be made in two or more parts which may be bolted or otherwisesecured together in any suitable manner, while the downwardly extending part a where such part is provided, so

may be of any other suitable form. The device mayalso be made of any other metal or material for instance wood or reinforced con- 7 crete. Ina slightly modified construct-ion the post a may be provided with three or more upstandingarms b as will be readily understood.

hat I claim is 1. A'bollard or mooring post comprising a vertically disposed pillar, a plurality of splayed posts rising from the upper end of the pillar, and laterally projecting arms adjacent the junction of the lower ends of the posts with the pillar, the arms having their under faces inclined downwardly from the pillar to their extremities. 2. A bollard or mooring post comprising a vertically disposed pillar, a plurality of splayed posts rising-from the upper end of the pillar, lateraldiverging arms projecting from one side of the'pillar at the junction of the posts therewith, the upper surfaces of said arms being curved downwardly and meeting the under surfaces thereof in a sharp corner, and a laterally extendingan- .0 choring flange on the pillar below said arms.

In testimony whereof I have hereunto signed my name.
