i s Claims:- rci. 114-4236) 'Mo'st barges, particularly those of the s c-ow type having rakeends, substantially parallel sides and a flat or substantially flat bottom, have a tend ency to yaw and sheer about whenbeing towed,

particularly when the'distance between the tug and the barge is considerable and a long tow line is therefore required, which tendency is 'fre-' quently emphasized by wind and current conditions. As a result, much difiiculty is often experienced in towing such barges throughnarrow' or sinuous channels or in the neighborhood of other vessels, piers and the like, and'strandings and collisions sometimes result. -Moreover,'any material departure 'of the barge from its proper course brings it more or less at an angle to the latter and requiresthe expenditure ofadditional power on the part'of the tug to return it thereto,

assuming it can be'brought back at all.

- Various expedients and devices have been proposed with a view to remedyingthese condi tions by constraining the'barge to properly follow the tug, at least under theusual conditions encountered when towing vessels ofthis general class, but as far as I am aware none of them has been entirely satisfactory for its intended pur pose.

It is therefore the principal object of this invention'to provide means automatically operative to cause a barge or other generally similar vessel to maintain a proper course after the tug or other vessel by which it is being towed irrespec tive of local tide and wind conditions and the like. r

A further object of the invention is'the' provis'ion of means of the character aforesaid' which are effective to cause'the barge to substantially follow the course of thetug when the latter is proceeding through sinuous channels, necessitating frequent turns to starboard or port, and thus prevent the barge from grounding on one side or the other of the channel because of inability to properly respond to thevariations in the course Of the tug.

' Still further objects of the invention are the provision of apparatus which is automatically effective to prevent the barge from yawing, or

sheering about whenbeing towed withlia long hawser by operating the rudder in the properdi-,

motion to return the barge to its truecourse whenever it tends to depart therefroinj which is simple and rugged in construction, comparative- 1y cheap, not liable toga out of order orbecome damaged under the'conditions ofuseto which such apparatus is necessarily subjected, and,

which may be readily installed on existing barges as well'as on new ones while they are being built.

' Other Object'aadVantags and novel"features of design, construction and arrangefne'nt inherent in'o'r comprehended by the invention are hereinafter more particularly: mentioned or will which Fig. 1 is a fragmentary plan view of the apparatus operatively installed adjacent-the bow of abarge of the type to which the invention is particularly applicablej Fig. 2 is a fragmentary side elevation" of the parts shown in Fig.1; Fig. 3 is a detail view of one of said parts, and Figs. 4, 5 and dare respectively diagramamtic views designed-to show the operation of the invention under various conditions. Like characters of reference are usedto designate the same parts in the several figures. v 1

Ilhe i' vention is of particular utility when-in-. stalled ona barge or generally-similar vesselhav ihg a'bow rudder, and I havetherefore shown in conventional "typeprovided'wi'th a bow rudder R which may be of any preferred shape and construction. In accordance with the usual practice, the rudder is mounted at the lower end of a rudder stool; S extending through a rudder port P to'terminate at a suitable distance above the 'deck D of the barge@ In accordance with the present invention, I fixedly though preferably removably secure to this projecting end of the rudder stock a collar 1' by means of'a pin or bolt 2 orin any other suitable way so that thecollar will turn with the stock, a plate 3 being desirably fitted beneath the collar and secured'to the deck to compensate for the sheer-of the latter and'aiford a suitable bearingfor the lower face of the collar so astop'ropp the drawing a portionof the bow of a barge B'of H Y the collar and thus lying athwartships when the rudder is parallel with the keel. At a suitable dis- .tancelastern of the rudder stock and collar, '1 sea bitt or post generally desigcure tothe deck D nated-as 6, the center of which is invertical f r alignment with the keel. The bitt comprises 'a base 7 having flanges adapted; for the reception of bolts 8 for securing it to the deck'a-nd,'preferably, a downwardly projecting shank 9 inserted in the structure of the barge to afford additional rigidity to the post as a whole. As best shown in Fig. 3, at a suitable'di'stance above the deck the 7 post is. reduced in diameter to forin a shoulder 10 anda stem 11 projecting thereabove about which is rotatably' disp'o'seda 'collar l5 the low'e'r face I the shoulder,' and for holding of whichseats on I the collar in place on the-stern suitablefmeans are provided such, for example,- as a keeper plate ldoverlying theupperfaceof thec'ollar and' rethereto by abolt 17 threaded into stern, the collar thus being niovabl secured the upper end'of the free to rotate upon the latter;

The collar 15'is provided with a'yoke 18', preferably integralwith the collar, having oppositethe yoke although preferably somewhatlonger,

and also, above this yoke, with a forwardly errk tending jaw 19 likewise preferably integral with'f' the collar adapted to receive and retainftherearji end of a tiller which projects forwardlyin the same vertical plane asthe'ruddertoterminate of thetillen'andrelieve thebitt land associated parts toga considerable extent from stresses which would otherwise be imposed thereon by the weight and downward pull of the towing vca ble or hawser Cleading to the 713-118; Orxgqtl-rer towing-vessel." cableis attached to the forward end of -the tiller many-suitable way; conveniently by e 1a hook secured=--to,.-,the i nr el ei-fh i r t having a removable latch-pin 3l fiective tospref vent the eye in the end of the cable fro m slipping out'of the hook after it is engage fihereover.

5. The combination with a barge or the like having a bow rudder and a rudder stock, of 'a ser is operative to turn the rudder through a my invention, I claim and desire to protect by Letters Patent of {the sponding arms of the yokes, an arcuate track disposed beneath the forward end of the tiller on bitt, a tiller normally extending forwardly from fore and aft position inducedby changes in the angular relation between the barge and the hawgreater angle to direct the bow of the barge in a similar direction. a

v8. The combination with a barge or the like having a bowrudder, of rudder actuating means comprising a bitt,-a tiller supported for oscillation on the bitt, extending forwardly therefrom, and i l adapted for connection to'the towing hawser, and means interconnecting the tiller with the rudder operative. when the tiller is swung to either side 3.4;;

from normal fore and aft position by a change in the angular relation between the barge and the hawser to turn the rudder in the same direction through a progressively greater angle and thereby alter the course of the barge,
