Description

Patented June 24, 1930 THOMAS Hl wILLs, or ivIINNnA'PoILIs,` MINNESOTA ANCHORk rrorsi` Application iledseptember 26, 41928. Serial NO."308,512.

My invention relates Vto boat anchor hoists and has for its object to provide adevice by means of which theusual boat anchor rope maybe guided so as to hold the same away from the side of the boat and by means of which the rope may be locked from movement when the anchor is in raised position.

Another object of the invention resides'in providing a device whereby the-.boat anchor rope may be readily manipulated from any position within the boatproper.`

Another object of theinvention resides in construct-ing the device witha plate-like member adapted to lie along the-gunwale of the boat and having an overhanging portioneX- tending outwardly therefrom and in attachy .ing the locking device to said overhanging portion in such a manner that the same directs the anchor rope` away from the side of theV bOat. v i A still further object ofthe inventi'on'resides in forming on said plate-like member and the overhanging portion thereof spaced earings, and in journaling within said bearing, a rotatable member serving to guide the anchor rope yand hold the same frommovement. o Y Y A feature of thelinvention resides in con- I structing said rotatable Vmeymberin halves, ,30 each formed with a hub and a flange, the hubs of said halves facing one anotherand providing an annular groove and in providing the flange of one of said members with a series of `spiraled groovesy communicating with said annular groove and in further providing the other flange with a series of projections adapted to extend into said` annular groove. Y

Other features of the invention reside inthel 40 details of construction `and inthe novel coinbination and arrangement of parts described in the specification and shown in the drawings. Y In t-he drawings,` Y

l 's a perspective view of a port-Ion of a row boat illustrating the appllcatlon of my invention thereto. A

The boat forming no particular feature of the tion `has not been shown indeta'il.A

The invention proper consists of ay supporting structure 14 which comprises a platelike member l5` adapted to be placed upon the gunwale` 11,V as bestjshown in Fig. 1. This plate-like member is formed with four downwardly extending

ears

16 and 17 which are adapted to straddle the sides of the gun- 4wale.` The ears 17 be tapped to receiveV thumb screws18by means of which the". de-

proper invenvice maybe detachably secured tothe boat.

Ifdesind, the structure may be permanently mounted upon the gunwale byaneans` of' screwsadapted to be receivedwithin'screw holes r19in Atheplate-like member 15 vand :.The plate-like member 15 is constructed'4 with anfoverhanging portionr20 which forms f a -continuation thereof and Y which projects outwardly beyond the side of theboat. This overhanging vportion is of angular formation7 asbest shown in- Fig. 2,"connnencing at the rear 'of said `plate-like member fandflar- -ing outwardly towardsl the` frontof the same.

Along theouteredge 21 ofthe overhanging p'ortion`20 is'formed auf upwardly extending 90 bearing 22 which is disposed in inclined relation tothe major .portion ofthe plate-like .membeiill A similar bearing 23 is formed -ingsare connected together at, the upper Vportion thereof byl means of a-'bridgemem- `.ber 24Y which,rin addition to stili'ening the said bearings,

serves in avman'ner to assistin mn iiange 31. Flange 31 is considerablywiderv than the flange 27 and ris formed with a plurality of helical spiraled grooves"32 which commence at the surface yof the hub and extend outwardly'toward the periphery of the flange 31. The two .

halves

26 and 27 are centrally bored as indicated at 35 and 36 to receive abol-t 37, which extends through'the

bearings

22 and 23 and serves as a shaft for rotatably `supporting the said rotatable member. The two halves are arranged upon said bolt with the

hubs

28 and 30 facing one ,anothen To prevent relative rotation between the two

halves

26 and 27, the hub 31 is formed with a socket 38 which is adapted towardv the interior of the boat.

to receive a pin 3,9 issuing outwardly from the face of the hub 28. Then the two

halves

26 and 27 are disposed between the bearings 22 andi23 the same form a unitary structure adapted to guide the rope and lock the `same against movement when desired.

In 1 he use of the device the'boat anchor rope which I have showniin Fig. laat 40, is

threaded through the annular groove 41, in

rotatable member 25 and between the hubs.

28 and 430 and the bridgeLlike member 24, leaving the free end- 42 of the ro-pe extend-ing .As long as the rope remains within the groove 41, the anchor may ber-aised and lowered at will. Then the rope is shiftedftoward the flange `i1-the same becomes engaged withinone of the spiral grooves -32. Upon slightly releas-` ing the tension lof the repethe weight 4ofthe anchor causes the rotatable member `26 to rotateI-in a clockwise .direction as v viewed from Fig. 1, which brings the rope in Vcontact with .the bridge-like member 24 in a manner yto firmly clamp the rope andvhold the same from tart-hea1 movement. It will beunoted in Fig. 4 that the bridge-likemember ,24 is beveled as indicated at 43 to further aid inA locking the-rope so as to hold the anchor in desired elevated position.- When it is desired to release the rope, the free end 42 thereof is drawn sufficiently backfto disengage. the rope from 'the particular .groove 32 in whoh it may have been ylodged and the rope is'then moved alignment with the groove 41 so as to cause the same to travel along sal'ld groove.l The anchor may then be raised Aand lowered as before. Inorder -to reduce the tendency of-'the'rope to cli-mb the flange 25, the projections 34 have been provided which, upon engagement with the rope, throw the same back into the groove 41.

The advantages of my invention are manifest. An extremely simple and ositive dcvice is provided whereby the anc or rope of a boat may be readily and conveniently manipulated by the user in Vany position within the boat. The user may also remain seated while operating the device, thereby adding to the safety ofthe occupants, rhe holding device serves to firmly hold the anchor rope and the Vgreater the weight of the anchor the firmer the same is held. The device may be constructed at aV nominal cost and can be either -detachably or permanently secured to the boat structure, A The y'dev-ice 4serves to di'- rect the rope away from the .side of the boat, thereby preventing injury to `the paint or vcovering on the boat and at the same time -preventingunnecessary wear upon` the rope. Several sizes of.l rope may be used with my invention sothat different sizes ofthe device .are unnecessary for any one type of. boat.

Changes in the specific form of myinven tion, as herein disclosed, may be made within the scope of what is claimed without departing from thespirit of my invention. Having described -my Y invention, what I claim as new .and desire to protect by Letters Patent is: A y y 1.
