Io ple, eiiicient and cheaply manufactured hoist permitting the raising of the anchor in a minimum of time so that the operator may be enabled to control the boat'and obviate any possibility of its grounding regardless of f, Weather and water conditions;

. Among other objects are the provision of a compact, readily demountable hoist which may be removed and .stored on the boat so as not to detract from the appearanceof the i boat when not inuse and require a minimum of storage space therefor.

' In the accompanying drawings forming a part ofthis specification, there is shown by way of illustration a construction embodying L.) all the features of the invention, which will now be described in detail and the features forming the invention then specifically pointed out in the claims.

I Inthe drawings: :1) Figure 1 is a top plan view of the hoist I partly broken away;

Figure 2'is a side elevation partly broken away;

end of the 'davit, the lower end of which is shown in Figure 2, and c Figure 4 is a side elevation of that side ofithe hoist opposite to that which is shown in Figure 2, showing the hoist in process of de- Bef'erring to the drawings, the hoist comprises three separable or demo'untable eleinents, viz, a base, a hoist proper and a davit, respectively, denoted generally as A, B and -l C1 The base or supporting member A, pref-v Figure 8 is a side elevation of the upper erably in the form ofa bollard or mooring post, is firmly secured to the boat at any convenient point as on the bow deck. The base or mooring post A may be hollow as shown and is provided with a central open- 50 ing 10 in its head and an inner boss 11 formed on its bottom plate and in alignment with the opening 10. A suitable series of circularly arranged spaced openings 12 are provided in the head of base A for a purpose to be described later.

'The hoist proper B comprises a suitable housing 13 having spaced arms 14, 15, between which is mounted a suitable reel 16 carried by a shaft 17 which extends through the arms 14 and and has secured thereto, outside arm 15, a capstan or gipsy 18 and, outside theopposite arm 14, agear 1,9. The gear 19 meshes with a smaller gear 20 carried by a stubshaft 21, the inner end of 65 which is housed within a boss 22 and is pref erably removably secured therein by a pin 23 carried by the boss 22 and cooperating with an annular depression 24 in the stub shaft 21. The gear 20 meshes,-also, with a 7 smaller gear 25 carried by a stub shaft 26 supported bya boss 27 on the housing 13 and is removably secured thereto by a set-screw 28 on the boss 27 which cooperates with an annular depression 29 formed in the shaft 26. 75 The ends of the shafts 17, 21 and 26 are extended outside theirrespective gears and are suitably squared or otherwise formed for the reception of acrank handle, not shown, and A the gears 19, 20 and 25 may be protected by a cover plate 30 for the protection of the operator, The bottom of the housing 13 is provided with a vertical shaft 31 which is adapted to pass through the opening 10 in the head of the base or mooring post A and is of suitable length to engage the boss 11 thereof for support of the hoist B. The hoist B may be rotatedupon the mooring post A and is secured in position thereon by a pin 32 which passes through the housing 13 into one of the openings 12in the top of the mooring post A to secure hoist B against rotation and in its adjusted position. There is a single Opening through the bottom of the housing which may be brought into line with any of the openings 12, and pin 32 then passed through the openings, the upper end of the pin being bent to form a handle, as shown in Fig. 1. 1 r

The reel 16 may be provided with a suitable'ratchet device by forming teeth 33 in one end plate thereof, with which cooperate/ea dog 34 secured to thearm 15 of the housing 13 by a suitable bolt 35, and with a hook or pin 1 for securing the end of a rope 50 to the reel. The unwinding or lowering opera ation of the reel and capstan may be controlled by a braking device as shown, com prising a brake drum 36 formed on the inner end of the capstan and a lined brake-band 37,

, .one end .of which is secured at 38 toa bracket ,ative to its housing 41.

39. carried by the housing 13 and the other end connected to ahand lever 40 pivoted at 40 to the bracket 39.

'The davit C, which is removably secured to the housing 13 by a housing 41, is suitably bent to'project forwardly of the hoist and carries at its upper-end an open faced block 42, having a pulley wheel 43, and is pivoted at 44 to a connecting member 45 pivotally secured at 46 to the davit C, the pivots 44 and 46 being preferably at right angles tocach other to provide. substantially universal movement for the block 42. The davit C maybe adjusted vertically within the housing 41- and is securedagainst rotation there in. For this purpose a collar 47 is secured in adjusted position upon the davit C by one or moreset-screws 48 and the forward face of the "collar 47 is squared at, 49 and received within-a similarly shaped recess in the housing 13 to prevent rotation of the davitC rel- The hoist operates as follows: The anchor rope 50 may be'secured tothe pin 1 on reel 16 for winding thereon, or'coiled about the capstan 18,and passed to the rope storage compartment as taken in. In taking up the anchor rope 50 the reel 16 or capstan 18 may be driven at full speed, at half speed, or at quarter speed by applying the crank handle respectively to the squared ends of either shaft 17,21, or 26,'but, preferably,c;dlirect drive is used until it is necessary tofbreak away the anchor. Then either half or quarter speed-will be utilized,dependinglupon weather conditions and howwell the anchor is caught. .The power required to break away the anchor may be considerably reducedby passing the anchor rope 50 through the open block 42 on the end of davit (l, so

that a substantially vertical'pull is exerted upon the anchor. A further advantage is securedby using the davitC in that it is unnecessary totake the anchor aboard immediately as it will be suspended clear of the boat by the davit C, so that the operator is free to operate the boat until under way or such time and, when the boat is at anchor, its upper end,

which is provided with an eye, is secured to a snap catch carried by the large anchor rope.

Under these conditions, when taking up the anchor, the heavy anchor rope is taken up by the capstan 18 until the upper end of the smaller hard layed rope is reached' Then the smaller rope is detached from the large anchor rope, passed through the open block '42 and secured to pin 1 on the reel 16 for winding thereon. vWhen the anchor is aboard, the smaller rope is unhooked from the anchor and remains reeled upon the hoist while the anchor and the large rope are stowed away.

In lowering the anchor, gear 20 may be disengaged from gears 19 and 25'by raising pin 23 out of groove 24 in shaft 21 and drawingit out of mesh with the other gears so that reel 16 and capstan 18 may run' free under control of the braking device.

WVhat is claimed is v '1. In ahoist for motor driven cruisers and the like, the combination with a mooring post, of a housing mounted on'the mooring post and freely removable therefrom, a shaft rotatably secured in said housing, a reel secured to said shaft withinthe housing, a capstan secured to the shaft outside the housing, and means for driving the shaft at difierent speeds. I

2; In a hoist for motor driven cruisers and the like, the combination with a mooring post, of a-housing mounted-0n the mooring post and freely removable therefrom, a shaft rotatably secured in said housing, a reel secured to said shaft, a gear secured to said shaft, a stub shaft removably secured in said housing and carrying a smaller gear meshing with the first mentioned gear, a shaft secured in the housing carrying a still smaller gear meshing with the second mentioned gear, and means on said shafts whereby a crank handle may be applied to any of said shafts for rotatingthe reel. V

3. In a hoist for motor-driven cruisers and the like, the combination'with a mooring post, of a housing mounted on the mooring post and freely removable therefrom, a davit removably and adjustably mounted in said housing, a shaftrotatably secured in said housing, a reel secured to said shaft a train of gears for driving said shaft, means on the shafts of a plurality of said gears whereby a crank handle may be applied to any of said shafts to rotate the reel under difi'erent'powers, and means for removably securing gears of the train in said housing for change of the gearlng.

In testimony whereof, I have hereunto set my hand.
