This invention relates to boat-anchors, and more particularly to an improved boa't anchor hoist mechanism.

A main object of the invention is to provide a novel and improved boat anchor unit provided with an anchor and a hoist mechanism therefor, the unit being very simple in construction, being easy to mount on a boat, and being very easy to operate.

A further object of the invention is to provide an improved beat a'nchor hoist device which is relatively inexpensive to manufacture, which is rugged in construction, which enables the operator to hoist anchor in a short period of time and with a minimum amount of effort, and which enables the anchor to be released instantaneously, whenever desired, bya'very sinfple operation,

Further objects and'advantages of the invention will become apparent from the following description and claims, and from the accompanying drawings, wherein: V

Referring to the drawings, the anchor unit is generally designated at The anchor unit comprises a generally rectangular housing |2 having side walls l3 and M, a top wall |'5, and a rear wall IS. The bottom of the housing is open, and the side walls of the housing are notched at H, H, allowing the forward portion of the housing to be fitted over the stern por-:- tion, shown at |8, of a boat in the manner illustrated in Figure 1. Designated at I9 is a transverse partition wall secured in the housing at the rear margins of the notches Threaded through the forward wall of the housing, designated at 20, are the-respective screw clamps 2|, 2|, each screw clamp beingprovided at its inner end with a clamping foot 22, and at its outer end with a knob 23. As shown in Figure-*1, the

"a claims. (01. 254-187) 2 housing l2 *may be rigidly seeur'ed on the stern portion |8 ora boat by tightening the clamping screws 2| so as to provide "clamping pressure between the foot elements 22 and the transverse partition wall 19. The foot elements .22 are rotatably mounted on the ends o'f the clamping screws 2|, whereby said "clamping 'screws' may be freely rotated relative to saldfoot elements.

Designated at His a first transverse shaft which is rotatably and 'slidabl-y *meimte'd in the side walls It and 4'of the housing 12. -As shown in Figures 1 and '6, said side walls are formed with inclined slots 25 in which the ends of the shaft 24 are rotatably and slidabl-y received. Shaft 24 has secured "thereon the discs '26, 2B which define therebetween 'a reel on which is wound the anchor hoist c'able 2l. One end of the cable is secured to the shaft 24 and the other end is secured to'th'e anchor, shown at 28. Secured on shaft "-2 4 is a relatively small second gear 29. Designated at 30 is a second transverse shaft rotatably mounted in the side walls I3, I4 of the housing -|'2. Botatably mounted on the shaft 30 is a relatively large first gear 3| which normally is 'in mesh with the gear 29, as shown in Figure 4. Fivotedto the side wall l3 or the housing 12 "at'33 is a second pawl or dog '32 which engages the periphery'o'f the gear 3| and prevents rotation of said gear'iin a counterclockwise direction, as "viewed in Fig'ure '4, but allows the gear 3| to *be'rotaited clockwise, Secured rigidly on shaft 30 is a third gear 34 dis- "posed adjacent to the gear 3|. Pivoted 'to the gear 3| at 35 is a first fpawlor'dog 36 which is engaged with theperiph'e'ry'of the gear 34 and which is biased into engagement 'with said periphery by a 'spring31 connecting the dog 36 to a pin 33 carried by the gear 3|. As shown in Figure 4, the dog 36 is arranged to allow the gear 34 to-be rotated counterclockwise relative to the gear 3|, but lo'cks the gear 34 to the gear 3| for clockwise rotation, 'asviewed in Figure 4. Secured on the shaft 30 is a'second reel 39, and encircling the shaft 30 between the reel 39 and the housing sidewall I4 is a helically coiled spring 40, one-end of the spring being secured to the side wall l4 and the other end of the spring being secured to-the reel 39. The spring 40 is wound up when the reel39 is rotated counterclockwise, as viewed from the right side of the hou'sing'lZ in Figure 5. Wound'on the reel 39 is a, cable 4| which extends 'slidably through the front wall 20 of the housing 12 and which has secured on its ends a knob 4-2. It will be seen that by pulling on *the k1'iob 42, the "reel 39 and shaft will be rotated counterclockwise, as viewed in Figure 4, causing the spring to be wound up. During this operation the dog 32 locks the gear 3|, but the dog 36 allows the gear 34 to be rotated counterclockwise relative to the gear 3|. After the knob 42 has been thus pulled outwardly, said knob is released and the spring 40 unwinds, causing the gear 3| to be rotated clockwise, as viewed in Figure 4, since the dog 36 looks the gear 3| to the gear 34 for this direction of rotation. As above explained, the dog 32 is arranged to allow gear 3| to rotate clockwise relative to the housing. Clockwise rotation of the gear 3| is transmitted to the gear 29 and to the shaft 24, causing the cable 21' to be wound up on the shaft, the winding up of the shaft 24 being more rapid than the rotation of the gear 3| because of the relatively large gear ratio between gear 3| and gear 29.

Designated at 43 is a third transverse shaft rotatably and slidably mounted in the side walls [3 and M of the housing l2, the ends of the shaft 43 being rotatably and slidably supported in slots 44 formed in the side walls 13 and I4. Rigidly secured on shaft 43 is a gear 45 which is in mesh with the gear 29, as shown in Figure 4. Shaft 43 is formed with the reversed helical grooves 46, and engaged on the shaft is a follower lolock 41 engaged in a conventional manner with the reverse grooves 46, so as to be moved longitudinally first in one direction on the shaft 43, and then to be reversed in direction after reaching the end of the shaft, so that it traverses the shaft inan opposite direction. The follower block 41 is provided with an eye member 48 engaging; around the cable 21 so as to guide said cablelongitudinally along the reel defined between the discs 26, 23 so that the cable will be evenly wound on the reel in one direction of rotation of the shaft 24, and will be smoothly unwound from the reel in the opposite direction of rotation. The block member 41 is' slidably supported in a transversely extending channeled track member 49 secured to the rear wall N5 of the housing [2. Hinged to the rear wall l6 above the track member 49 is an arm 59 which has secured to its free end a transversely extending bar member 5| carrying a rubber pressure strip 52. The bar member 59 is biased counterclockwise, as viewed in Figure 7, by a coil spring 53 bearing atone end on the arm 50 and bearing at the other end on the. upper marginal portion of the rear wall I 6 in the manner shown in Figure 7, thereby biasing the pressure strip 52 into engagement with the cable 21 wound up on the reel carried by shaft 24. V

Designated at 5 4is an arm pivoted at 55 to the side wall I3 of the housing. The shaft 24 extends rotatablythrough the intermediate portion of the arm 54. Pivotally secured at 55 to the top end of. the arm 54 is a rod member 51 which extendsEslidably through the front wall 20 of the housing 12 and has a knob 58 secured on its forward end.

Threadedjonthejrod member 51 is a" nut 59 limiting movement of the rod member 51 to the left, as viewedlin Figure 4. Designated at 69 is an angle bracket secured to the side wall [3 of the'housing'through which the rod member 51 slidably passes. Designated at 6| is a washer mountedon the rod member adjacent the nut 59, and encircling the ,rod member between the washer 6i and the angle bracket 60 is a coil spring 62 which .eXerts biasing; force on the washer (ii, biasin'g'the' rod member 51 to the left, as viewed in Figure 4, and thereby biasing the gear 29 into meshing engagement with the gear 3|. By exerting pressure on the knob- 58, however, the rod member 51 may be moved to the right, as viewed in Figure 4, causing the arm 54 to be swung clockwise, thereby disengaging the gear 29 from the gear 3|. The gear 45 and the shaft .43 are simultaneously moved rearwardly, along with the shaft 24, since such movement is permitted by the slots 44 supporting shaft 43. Normally, the gear 29 is locked against clockwise rotation, as viewed in Figure 4, because the gear 3| is locked against counterclockwise rotation relative to the housing by the dog 32. However, when the gear 29 is moved out of meshing relationship with the gear 3|, as above described, the gear 29 becomes unlocked and the cable 21 is therefore allowed to freely unwind by the weight exerted thereon by anchor 28.

It will therefore be apparent that to wind up the cable 21 and therefore to elevate the anchor, it is merely necessary to pull the knob 42- outwardly and then release the knob 42, allowing the spring 40 to unwind, thereby causing gear 34 to transmit torque to gear 3! through the dog 36, which causes gear 3| to transmit torque to gear 29 and shaft 24. This winds the cable 21 on the reel carried by the shaft 24. The above process is repeated as many times as is necessary to wind up the cable 21. When it is desired to release the anchor, the operator merely presses inwardly on the knob 58, thereby freeing the shaft 24 and allowing the cable 21 to unwind by the weight exerted thereon by the anchor 28. The slots 25, supporting the shaft 24, and the slots 44, supporting the shaft 43, allow said shafts to be moved rearwardly, to enable the gear 29 to be disengaged from the gear 3|. When pressure on the knob 58 is released, the spring 62 and the spring 53 move the elements back to their normal positions wherein the gear 29 meshes with the gear 3|. Since the gear 3| is normally locked against counterclockwise rotation, as viewed in Figure 4, the gear 29 is also normally locked.
