Description
Unite States Patent 3,078,374 Patented Feb. 19, 1963 3,073,975 WINDLASS Fraai: A. Benedict, Syracuse, NE., assigner to Bensons Anchors, line., Syracuse, NSY., a corporation of York Filed May i9, i969, Ser. No. 36,26@ l Slaan. (Cl. ZSLt-- This invention relates to and has as an object a new and improved power operated windlass for paying a line therethrough, which windlass is both simple and economical to manufacture, but yet is eiiicient and reliable.
The windlass comprising the preferred embodiment of the invention is intended to be used on small pleasure boats for paying in and out an anchor line to which the boat anchor is connected, but it is to be understood that the windlass may be used in any other desired manner.
The invention consists in the novel features and in the combinations and constructions hereinafter set forth and claimed.
In describing this invention, reference is had to the accompanying drawings in which like characters designate corresponding parts in all the views.
In the drawings- FIGURE l is a top plan View of the windlass comprising the preferred embodiment of the invention with parts omitted.
FIGURE 2 is .a fragmentary side elevational view with parts broken away and parts in section sho-wing the wind lass mounted on a boat surface and connected to a lower source.
FIGURE 3 is a cross-sectional view taken on the line 3--3 of FIGURE l, with the windlass cover shown attached to the windlass.
FIGURE 4 is a fragmentary cross-sectional view taken on line 4 4 of FIGURE l.
In the drawings, the windlass comprising the preferred embodiment of the invention, as best seen in FIGURE 1, comprises a base plate l@ which is provided along its side edges with a pair of apertures l2 to receive suitable screws, or the like i4, see FIGURE 2, for attaching the base l@ to a surface 16 of a boat such as the deck or the like.
In FIGURE 2, the base l is provided with an aperture i8 through which the shaft 2t) of a power source 22 of any suitable type extends. The power source is fastened by a bracket, or the like, 24, to the underside of the boat surface 16, and the surface i6 is provided with a clearance aperture 26 through which the shaft 2t? extends.
Mounted on the upper end of the shaft 2l) is a pulley 3d having a V-shaped groove 32 formed therein. As best seen in FIGURE 2, the groove 32 is provided with a plurality of ridges and grooves 34 and 36 so as to provide a frictional grip for an anchor line 38 threaded into the groove 32.
As will be obvious, the pulley Si! may be affixed to the shaft 20 in any suitable marmer such as by keying or the like, so that the pulley 30 will rotate with the shaft 29 when power is supplied by the power source 22 to the shaft 20.
The outer side edges of the base plate It) are provided with a pair of threaded raised portions 40, and a cover 42 is removably affixed to the base plate so as to enclose the pulley by means of threaded screws, or the like, 44, which are received in threaded apertures formed in the raised portions 4t?.
Positioned a spaced distance from the outer periphery of the pulley 3G, and pivotally mounted on a pin 46, received in the base plate 10 and an aperture formed in the cover 42, is a follower arm 4S. The opposite end of the arm i5 has a follower roller journalled thereon by means of a pin 52 received in the top and bottom surfaces of the arm 43. The arm. 48 is bifurcated so as to receive the follower roller 5t), and is provided intermediate its ends with a web portion 53 which joins the upper and lower bifurcated portions of the arm 48. The web S3 forms a rst aperture 54 extending through the arm 48 adjacent the pivotal mounting about the pin 46 and one run 56 of the anchor line 3S extends through the aperture 54, and this run is connected to the anchor, or .the like.
The webbing 53 and follower roller 50 form a second aperture 58 extending through the follower arm 45 and a second run 6d of the anchor line is threaded therethrough, and through an aperture 62 formed in the base plate It).
The aperture 62 is aligned with an aperture 64 formed in the boat surface i6 as to pay the run 63 of the anchor line 38 through the aperture 64 and into the boat to coil the line when the anchor is being raised.
A threaded boss 68 is formed on the base plate 10 a spaced distance from the follower arm 48 and a threaded shouldered stud 7@ is received in the boss 68. The reduced forward portion of the stud 7i? has a portion of a coil spring 72 mounted therearound, and the opposite end of the coil spring 72 is received about a stud 74 projecting outwardly from the web 53 formed in the follower arm LES, whereby the spring 72 serves to urge the ann 48 `about the pivot point 46 toward the pulley 30, so as to urge the roller 5o into the groove 32 to guide and retain the run 69 of the anchor line 38 in the pulley 30.
The opposite side of the web 53 is provided with a forward projecting separator member 76 which is formed at its forward end with a curved arcuate surface 78 and is received in the pulley groove 3S. The separator 76 serves to separate the runs 56 and 6h of the line 3S as the line is being payed around the p-ulley 30.
As will be obvious, the amount of force exerted by the coil spring '72 on the arm 48 may be varied by rotating the 4threaded stud 70.
As best seen in FIGURE 4, it will be seen that the aperture 62 formed in the base plate 10 is provided on the. upper surface of its inner side with a beveled portion 64, to facilitate the entrance of the run 6d, of -the line 38 into the boat through the aperture 64 formed in the surface 16. In addition, the underside of the cover 42 is provided with a boss Si?` which is provided with -a centrally located, and downwardly opening arcuate notch 82 to also guide the inward or outward movement, as the case may be, of the run 60 of the anchor line 38.
As will be obvious, I have provided by my invention, a new and improved power operated windlass which is both simple and economical to manufacture, but is at the same time safe, reliable and efcient in operation.
What I claim is:
A power operated windlass for paying a boat anchor line comprising a base adapted to be iixedly mounted on the boat deck, a pulley journalled on said base plate for rotation in a plane parallel and adjacent to said base plate, power means for rotating said pulley, said pulley being formed in its periphery with a groove for the reception of the-anchor line looped thereabout, a bifurcated arm pivotally mounted at one end to said base plate and extending from said pivotal mount in cio-planar and spaced relation to said pulley, a roller journalled in the opposite free ends of said arm, the runs of said line extending through the bifurcated arm about said pulley, the pivoted end portion of said arm guiding one run of the line tan gentially to the pulley, the other run of said line extending between said pulley and said roller, spring means yieldingly urging said arm toward the pulley to cause said roller to press said other run of the line into the pulley 2,326,670 Patterson Aug. 10, 1943 2,773,668 Robins et al Dec. 11, 1956 2,802,636 Sandford Aug. 13, 1957 2,875,981 Hunter Mar. 3, 1959 2,922,623 Simmons Jan. 26, 1960 2,947,516 Jackson Aug. 2, 1960 te u
