`lune 3, 1952v A. E. ROGERS ANCHOR RAISING AND LOWERING MEANS 2 SHEETS- SHEET 2 Fig. 4

Filed Dec. 15, 1950 Figa ` Andrew E. Rogers I IN V EN TOR.

BY wwmm Patented June 3, 1952 UNITED STATES TENT oFFi-cE 41laims.

This invention relates generally to means for anchoring boats and more particularlyto -an anchor assembly wherein an anchor'israisedfand` lowered by power means and wherein the anchorl by hydraulic and electric means;,and the power for the weighing of the anchorgbei-ngautomatically interruptedy when the anchorv has been fullyraised.

Another object of this invention isy to; facilitate the use of one or two largeanchors, equal tothe weight of possibly twice that'number off anchors otherwise required* when the weight ofi the anchors must be limiteddueto the difficulty-y of handling the same on the deck, the, mushroomtype of anchor used in this invention/being ordi'- narily larger and more eiiicient than; those; ordinarily employed on equal size boats.

Another object of this invention is-to facilitate the streamlining of decl: portions of-boats,-, and it is believed that this invention is adaptable for use with vessels of all-types andl tonnage, including submarines and hydro-planes.

A last object to be mentioned' specifically;y is to provide anv anchor assembly whichisl relatively inexpensive andf practicable to manufacture, which is safe aswell asv convenient to operate, easy to install, and' generally eicient in operation.

With these objects denitelyv in view,4 together with other objects which willdappear hereinafter as this description proceedsvthis invention consists in the novellcombination, and arrangement of elements and portions as will/ be hereinafter described in detail'v in the speciicatiomwparticularly pointed out in they appended claimajand illustrated in the accompanyingdrawings, which form a material part off this,l application,l and wherein:

Figure 1 is a side. elevational'view of a boat with this invention operatively mounted, thereon.. portions f the` boat .tei-ne broken aware-11d the underlying portions being shown in elevation and vertical section in order to more perfectly disclose the general arrangement of the elements in this invention;

Figure 2 is a fragmentary bottom plan view of a portion of the hull of the boat, showing the 2 mushroom anchor in place on the keel of theV boat;

Figure 3 is a vertical sectional view of what will be hereinafterreferred to as tlfie-anchorvvayy and adjacent structure, this viewr being on an enlarged scale;

Figure 4 is an other vertical-` sectional viewf ofV the same structurezas'that shown in Fig-ure 3.;

Figure 5 visalower plan view-f otY the anchor-- wa-y, with the anchor and anchor chain removed;

Figure 6 is an enlarged fragmentary-view, rep-f resenting a vertical cross-section of a part: of the anclf-iorway;` and Figure '7A is adiagrammatic-view showing the electrical and hydraulic systems used inthis invent-ion.

Similar characters of reference designate similar or identical elements and portions throughout the specification and' throughoutfthe:differentviewsin the drawings.

The environment wherewith this invention williY bel used will ordinarily includedeck structurey i0, a keel I2, and. an instrumenti board lliy in the cabin of the boat whereon thed'evice is installed. The anchorused preferablyincludes-a shank I6 anda mushroom head i8. Theanchorway 2li-s ordinarily vertical and' is tubular, the lowerKV end portion of the anchorway being reduced:y asindicated at2| to pass through-the keel l2; A casingl 22, shown as integral with the upper-end-*portion of theanchorway 2D, will-fbe'securedfto the deckv structure l0" or other fixed' membersv in the; boat. It shouldbe noted here that the casing 22 Ywill ordinarily be abovethe water linewhe-n the boat with this invention thereon ,isf in use.

Thek lower endY portion of` the anchorway 2D.,

including the? reduced portion 2|; thereofL is provided witharr. axial recess-24 to receive the shank l of; the anchor,V while the major. portion` of the tubular anchorway has: achannel 2t of, cruciform character, as best illustrated. in Figure 5, the ends of thev arms of the cross in this cruciform channel being` rounded, asindicated` at 21, to fit the edge portions. of links of the anchor chain A28,. The maximum. transverse dimensions of this cruciform channel 2,6 is substantially equalv to the transverse dimensions of one ofthe links, of the chain. 28,1 so that this anchorway is self-sealing against entry of sea water into the hull. It should be noted that fair-leaders 30 and 32 are provided at the lower and upper ends'of the cruciform channel 26.

An anchor chain drum 34 is rigidly secured to a shaft 36, and this shaft is journaled in simple bearings provided in the casing 22. Gear wheels 3B are rigidly mounted on the drum 34 and pinion gears 40 drive these gear wheels 38, the pinion gears being i'lxed to the drive shaft 42 of an electric motor 44, the latter being mounted exteriorly of the casing 22, as clearly illustrated in Figure 3. In order to arrest the anchor when desired, a brake drum 46 is secured to an end of the shaft 42. An expanding brake band 48 is operatively associated with the brake drum 46 and is controlled by a hydraulic cylinder 50. A hydraulic line 52 leads from the cylinder 50 to a manually operated valve 54, preferably mounted on the instrument board 14. The valve 54 controls iow of hydraulic fluid to a conduit 56 connected with a hydraulic pump 58,

the latter being operated by an electric motor f 60, and a reservoir 62 is also operatively connected with the hydraulic system. Manually operated switches 64 and 66 control power lines leading to the electric motors 60 and 44, respectively, and the electric motor 44 is further controlled by a switch diagrammatically indicated at 68, this switch having an actuating push bar 'i0 normally extending beneath the lower level of the keel I2, adjacent to the lower end of the anchorway 20, so that the head I8 of the anchor will engage the bar 18 to open the switch 68 and interrupt current to the electric motor 44 when the anchor has been completely weighed and is in position on the bottom of the boat.

In order that the helmsman may know the depth of the anchor at all times, a fathometer 12 will be mounted on the instrument board 14 and operatively connected with the drum 34.

except the portion 16 of the anchor chain, on`

that side of the drum 34 remote from the channel 26. This chain guide 14 is also, of course, generally tubular and the channel therein is also cruciform and is provided with upper and lower fair-leaders 18 and 80.

An auxiliary brake is provided on the anchorway 20, this brake comprising a screw threaded radially in the anchorway 2D, as indicated at 82, and the screw 82 has a hand wheel 84, or some analogous structure, whereby the screw 82 can be made to enter the channel 26 and engage the anchor chain 28 in cases of emergency when it is desired to halt the movement of the anchor.

The operation of this invention will be clearly understood from a consideration of the foregoing description of the mechanical details thereof, taken in connection with the drawings and with the above recited objects. It will be clear that the motor 44 will operate the drum 34 in the weighing of the anchor, when the hydraulic brake system 4 6--64 is inoperative, the weighing action being stopped by interruption of current to the motor 44 when the anchor has been fully retracted and the switch 68 opened. The anchor is ordinarily heavy and will lower under the influence of gravity, when released. The anchorway is self-sealing and the small amount of moisture raised by the chain 28 will be drained from the casing 22 through the outlet 86.

Having described the claimed as new is:

1. An anchor assembly comprising an anchorway having an upper and lower end, a casing integral with said upper end and a reduced portion on said lower end, a chain drum rotatably journaled in said casing, gear wheels secured to the ends of said drum, a drive shaft rotatably journaled in said casing, pinion gears on said drive shaft operatively engaging said drum gear wheels, means to brake said drum mounted on said drive shaft, the lower end of said anchorway being further provided with a recess therein, said upper end having a guide channel therein of cruciform shape communieating with said recess, an anchor head abutting said lower end, an anchor shank disposed in said recess, an anchor chain extending from said anchor shank through said guide channel and around said drum and power means to operate said drive shaft.

2. The combination of claim l, wherein said chain links comprise a sliding closure for said guide channel.

3. An anchor assembly comprising an anchorway having an upper and lower end, a casing integral with said upper end and a reduced portion on said lower end, a chain drum rotatably journaled in said casing, gear wheels secured to the ends of said drum, a drive shaft rotatably journaled in said casing, pinion gears on said drive shaft operatively engaging said drum gear wheels, means to brake said drum mounted on said drive shaft, the lower end of said anchorway being further provided with a recess therein, said upper end having a guide channel therein of cruciform shape communicating with said recess, an anchor head abutting said lower end, an anchor shank disposed in said recess, an anchor chain extending from said anchor shank through said guide channel and around said drum and power means to operate said drive shaft, said anchorway includes an auxiliary brake comprising a screw threaded radially into said anchorway and having one end extending into said guide channel and engaging said chain, the other end of said screw having control means thereon.
