ATTORNEYS United States Patent ANCHOR BOOM ASSEMBLY Fred C. Good, Philadelphia, Pa., assignor to Fred C. Good 8: Sons, Inc., Philadelphia, Pa., a corporation of Pennsylvania Application July 2, 1958, Serial No. 746,242

'5 Claims. (Cl. 114-210) This invention relates to anchor booms and more particularly to anchor handling devices of the type which are especially adapted for use on boats in the 20 to 50 foot class.

This invention is a further development of the anchor boom forming the subjectmatter of my co-pending application Serial No. 659,625, filed May 16, 1957, now US. Patent No. 2,870,732 and as pointed out in that application, the problem of raising or lowering the anchor of small boats in rough seas is one which has been met with disastrous results. For example, in prior anchor handling arrangements on boats of the type here involved, many accidents have occurred to persons due to an inability to maintain their balance on the forward deck of such a boat in rough seas while either taking in or lowering an anchor. Further, the probability of such accidents is enhanced by the fact that under these circumstances the deck on which the person handling the anchor must stand is usually wet, thereby presenting a slick and slippery surface on which the person must operate. It is therefore an object of the present invention to provide an anchor handling boom arrangement whereby the anchor may be loweredor raised without requiring the presence of a person on the forward deck of the boat.

It is a further object of the present invention to provide an anchor boom supporting structure mounted to the deck in such a manner that the anchor will always clear the sides of the boat during the raising and lowering operations.

It is still a further object of the present invention to provide an anchor boom of the type referred to which is pivoted about a horizontal axis to permit the boom to be automatically self-aligned with the general direction which the line to the anchor leads.

Still another object of this invention is the provision of an anchor boom of the type referred to which is detachably connected to the boom supporting structure to facilitate storage of the boom when it is not in use.

Other objects and advantages of the present invention will become apparent in the following detailed specification read in connection with the attached sheets of drawings in which:

Figure 1 is a side elevation partially in section of a preferred embodiment;

Fig. 2 is a top plan view of the device shown in Fig. 1;

Fig. 3 is a top plan view similar to Fig. 2 but showing an anchor received within the boom for storage purposes;

Fig. 4 is a rear plan view of the device shown in Fig. 1; and

Fig. 5 is a section on line 5-5 of Fig. 1.

Referring now to the attached drawings, it will be seen that the boom generally designated by the numeral is in the form of a U-shaped channel throughout the central portion of its length, the bottom portion 12 thereof being formed having a plurality of slots 14 to decrease the overall weight of the boom. Near the outboard end of the boom a pulley or sheave 16 is provided having arcuate line contacting surfaces to conform generally to ice the shape of an anchor line 17. The bottom portion of the boom immediately adjacent the sheave and outwardly therefrom is open so that the anchor line 17 may pass from the sheave 16 downwardly through the open portion and be attached at its lower end to an anchor, not shown. The inboard end of the boom is formed having a cover portion 18 which may be in the form of a plate welded or otherwise aflixed to the top of the boom or may be integrally formed in the boom. A pin 19 is positioned transversely on the lower edge of the inboard end of the boom to support the anchor line 17 above the bottom portion 12 of the boom. Thus, the anchr line 17 passes over the sheave 16, under the cover portion 18 and over the pin 19 to a winch or other power operated haulage mechanism, not shown, located inboardly from the boom and controlled from the cockpit of the boat. As will be more fully pointed out hereinafter, this arrangement functions to hold the boom in a horizontal position when the tension in the anchor line exceeds the weight of the anchor. The outboard end of the boom is provided with an upwardly inclined portion 20 comprising a bifurcated abutment to which is secured a ring 22. The ring 22 serves as a stop, against which a portion of the anchor rests when fully retrieved as shown in Fig. 3, with the shank of the anchor received within the boom and the flukes of the anchor engaging the bifurcated abutment.

The boom supporting structure is in the form of a plate 24 having apertures 26 through which bolts may be inserted to attach the supporting plate to the deck of a boat. Fixedly secured to the outboard end of the supporting plate are a pair of upstanding plate members 28, the details of which will be explained more fully hereinafter.

The boom 10 carries of pair of transversely extending

pins

30 and 32 on its lower edge. The

pins

30 and 32 are provided with

heads

34 and 36 respectively and are of such a length that the inside distance between the heads is slightly greater than the spacing between the upstanding plate members 28. Each of the plates 28 are formed having a horizontal slot 38 terminating in a downwardly curved portion 40. The slot 38 is dimensioned to receive the body portion of the pin 32. The rearward edge of the upstanding plate members 28 is arcuate, having a radius substantially equal to the distance between the outboard pin 32 and the inboard pin 30. The upper end of the arcuate edge terminates in an abutment slot 42, so that as the boom is pivoted about the pin 32, the amount of pivotal movement is limited by the engagement of pin 30 with the slot 42 in the upstanding plate members 28. Due to the particular configuration of the slots 38 and 42, the boom is detachably mounted without danger of accidental detachment, and further permitting suflicient pivotal movement to function in a highly effective manner.

As shown in Fig. 4 the pin 19 is formed having a portion of reduced diameter 44 near one of its ends for engagement by a pivoted latch member 46 on the mounting plate 24. The latch is normally disengaged during anchor raising or lowering operation and may be used to secure the boom 10 in a horizontal position if desired.

In operation, and starting with the boom in the position shown in full line in Fig. 1, the latch 46 being disengaged from the reduced diameter portion of pin 19, the operator in the cockpit merely actuates the haulage winch to permit the anchor to be lowered alongside the boat over the sheave 16. Since the latch 46 has been disengaged the boom is free to pivot about the pin 32 under the weight of the anchor and the tension in the anchor line so that the end of the boom will be automatically pointed in the general direction of the anchor. The degree of pivotal movement, however, is limited by the slot 42 in the up standing plate members 28 engaging the pin 30. The dotted line showing of Fig. 1 shows this most clearly. When it is desired to raise the anchor, the winch is again operated to establish tension in the anchor line and thus raise the anchor toward the sheave 16. At this point it becomes clear that as the anchor approaches its upper limit, -i.e,, the sheave 16,)the tension in theflanchor line functions to exerta downward force on the pin 19, pivot ing the boom about the pin 32 into a horizontal posi tion. 7 If it is desired, the latch 46 may be engaged with the pin 44 and the boom may be left inthe position substantially as shown in Fig. 1. On the other hand, if de: sired, such as when a long cruise is contemplated, the latch 46 may be disengaged and the entire boom and anchor lifted up and rearwardly such that the 'pin 32 disengages from the downwardly turnedportion '40 of the slot 38. The entire boom and anchor may then be stored inboardly on or below the deck of the boat.

Thus it is seen that by this invention there is provided a highly effective anchor boom assembly which may be easily disassembled for storage purposes and yet which is 4 pin carried transversely of said boom and engageable in the outboard end of said generally horizontal slot for pivotally supporting said boom with respect to the deck of a boat therein; and a second transverse pin carried by said boom, spaced inboardly from said first pin, and cooperable with said arcuate inboard edge and abutment slots thereon to limit the pivotal movement of said boom about said first pin. I I f 2. The combination recited in claim 1 including means carried by said boom and plate for latching fsaid boom in ahorizontal position to prevent pivotal motion.

3. The combination defined by claim 1 in which said boom comprises a channel member throughout its length highly effective to retain the anchor away from the side of a boat as it is being raised or lowered. Further, it now becomes apparent that an anchor boom assembly is provided which permits a complete lowering or raising of a' boat anchor without requiring the presence of a person on the boat deck in rough seas or under other hazardous conditions.
