DRIVING MECHANISM FOR THE WINDLASSES AND CAPSTA NS OI VESSELS.

. 7 Application filed February 8, 1927. Serial No. 166,628.

This invention relates to novel and ingenious power mechanism for driving windlasses, capstans, and the like on board of vessels, particularly warships; and more especially the invention applies to novel and simplified gearing and other transmission means between the prime movers or power appliances. consisting for example of variable speed driven pumps actuated by variable speed driving pumps, and the wlndlass, capstan, or other instrumentality to which the power is to be applied for the purpose intended. which in.the case of the Windlass is to liftor drop the anchor, and irfiithe case of a capstan is usually to warp s 1 I -Ieretofore the connections between the pumping mechanism and the windlass or capstan have consisted of a multiplicity of shafts and gears'arranged in a complicated and expensive manner, requiring much space and utilizing many mechanical elements. The object of my invention is to simplify the mechanism by using asv few shafts and gears and pinions as possible, thus economizing in space and in the cost of machine construction, besides concentrating in a small area and compacting thus particular transmission machinery, so as to secure greater strength, easier and quicker manipulation, surer and more-accurate results, and numerous additional advantages over the complicated mechanisms now in use.

With these and numerous other objects in View the invention may be said to consist essentially in the construction, combination, and arrangement of parts, substantially as will be hereinafter more fully described, and then pointed out in the ensuing clauses of claims.

In the accompanying drawing illustrating my invention:

Figure 1 is an incomplete top plan view in partial irregular section on the line 1, 1, of Figure 2 of my improved mechanism for operating a ships Windlass and similar ma chines.

Figure 2 is a vertical sectional elevation of the same on the hue 2, 2, of Figure 1.

Figure 3 is a top. plan of a pair of windlasses and capstans,"as they are arranged in Figure 2.

, Figure 4 1s an enlarged detailview of the simplified gear and shaft combination for First, however, 'I will describe the powerappliances for actuating the gearing. For th1s purpose I have selected the appliances in use to-day on many battleships, cruisers and other vessels, not because my invention restricts me to a combination of my simplified gear transmission with such power machinery, but because it will commonly be used with such machinery, though it will be obvious that it may be used with other classes of driving machines. As I do not claim thepower machines as my invention, and as they are already in extensive and efiicient use, I- do not consider. it necessary to describe or to show the same in great detail, but only in general outlines, in order to indicate an operative combination.

It may be said that these power mechanisms include essentially variable speed driving pumps, as A and A, and variable speed driven pumps, as B and B, with connections whereby the drivin pumps drive the driven pumps, the dup icate arrange ment being set forth to correspond with the duplicate windlasses and duplicate capstans, which I have preferably illustrated in order to better explain the invention.

In the sectional plan view of Figure 1 I have shown, in outline only, a bedplate 1, in which are arranged the two driving pumps A and A, whichare operated by an electric motor 2, deriving its power from some suitable source of energy, and having a shaft 3 which runs from motor 2 to the two-pumps A and A, said shaft 3 being carried in bearings 4, 4, and being provided with a coupling or clutch 6, a brake'5, and

any other customary accessories for assisting in the operatlon thereof and its control. The pump-A is controlled by a hand-wheel a on a shaft or connection a that leads to the pump A, and the pump A is controlled by a hand-wheel a on a shaft or connection a that leads to the pump A, said shafts a and a, being associated with interior mechanism in the pumps which controls their action in starting, stopping, reversing, etc.

In order that the pumps A and A may respectively drive the driven pumps B and B, certain piping leads from pump A to pump B, and other piping from pump A to pump B. From pump A to pump B run two pipes 7 and 8, and from pipe? a connecting pipe 10 leads into one side of pump B, while from pipe 8 a connecting pipe 9 leads into the other side of pump B. Pipe 7 has hand valve 11, and pipe 8 has hand valve 12; while pipe 10 has hand valve 14 and pipe 9 has hand valve 13. Similarly from pump A to pump B run two pipes 7 and 8, and from pipe 7 a a connecting pipe 10 leads into one side of pump B, while from pipe 8 aconnectingpipe 9 leads into the other side Pipe 7 has hand valve 11 of pump B. and pipe 8 has hand valve 12; while pipe l0 has hand valve 14 and pipe 9 has hand valve 13*. Thus here are two pipe systems for conveying fluid, as oil, to drive the two pumps, one for each of the two windlasses. To enable the prime mover pumps A and A to operate the pumps B and B respectively, in case of breakdowns, instead of pumps B and B, as normally, the pipe 7, is connected with the pipe 7 by a pipe 17 provided with a hand valve 15, and the pipe '8 is connected with the pipe 8 by a. pipe 18 provided with a hand wheel 16.

Normally the pum A is to drive the pump B, and in so doing tie valves 11, 14, 13, and 12 will be open, While the valves 15 and 16' will be closed. And normally the pump A will drive the pump B, and in so doing the valves 11, 14 13, and 12" will be open, while the valves 15 and-16 will be closed as before.

It will be evident however that the pump B may be driven from the pump A, in case the pump A is out of order and for the time being inoperative. In order to do this open valves 11, 15, 14, 12, 16, and 13, and close valves 13, 14, 11, and 12. Or to drive pump B from pump A, close valves 13, 14, 11 and 12 and open the others.

Obviously the pumping through pipes 7 and 7. will drive the pumps in one direction and pumping through pipes 8 and 8 will drive them in the opposite direction.

I will next explain the general arrangement of the windlasses and capstans or other equivalent machines, and their location in relation to the mechanism which drives them. In Figure 2 I show a cross section of the hull of a ship, S being the so-called skin of the vessel, E being one deck on which the windlasses and capstans are supported, and F being a lower deck (21 which the malass and capstanwill be located far forward in the bow. Of course there may beone or several of each of them. In the drawing I show two windlasses D and D, and nearing secured to the vertical shaft 45, by means of which it is rotated. Shaft has a hearing 46 provided with a suitable bushing, said bearing being integral with frame 47 which is fitted into or secured to deck E. Similarly. the windlass D has teeth (2! that are engageable by the anchor chain, and this wildcat part of the Windlass is keyed to the vertical shaft 45, which is bushed in bear-v ing 46 made integral with frame 47 that rests on or in deck E. In Figure 3 I show in dotted lines an anchor chain X running around Windlass D and dropping down through the opening Y, and a chain X running around Windlass D and dropping down through opening Y, the same being only a conventional method of showing the disposal of the anchor chains. Likewise the capstan 0 adjacent to the Windlass has its drum keyed to the vertical shaft 40 which'is hushed in a bearing 41 supported on deck E. Shaft 40 carries at its lower end a gear wheel 42, that meshes with another gear 43 secured on a vertical shaft 44 that is rotatable in suitable bearings. And in the same manner the capstan C is adjacent to the Windlass D and has its drum keyed firmly on a vertical shaft 35 revolvable in a hushed bearing 36 that is carried on deck E. Saidshaft 35 carries at its lower end a gear-wheel37 which meshes with another gear wheel 38 on a shaft 39 which-is supported in suitable bearings'so as'to'revolve easily as required.

I come now to the essential part of my invention which consists in simplified transmission gearing connecting the driving mechanism, or prime mover, consisting in the special example given, of pumps,- and the driven means, consisting ofwindlasses,

lil..

Ill)

capstans and the like devices,-the latter being operated together or independently, all

as I shall set forth in detail Heretofore this transmission mechanism has been com plicated and multifarious, but I have re duced the same to a very simple and com pact form. i

The driven pumps B and B, which in turn become driving means for the Windlasses and capstans, have respectively shafts 19 and 19; and the windlassD has shaft 45, the Windlass D has shaft 45, the capstan C shaft 40 and the capstan C shaft 35. The

problem therefore is for shaft 19 to drive shafts 45 and 40, and the shaft 19 to drive shafts 45 and 35. The gearing for doing this is shown in Figure 2 and in enlarged detail in Figure 4, in so far as it connect shaft 19 with shafts 45 and 40, and obviously the gearing connecting shaft 19 with shafts hub on a pinion 22 loose on the section 30 of the vertical shaft 29 which is coupled by coupling 48 to the wildcat shaft 45 of windlass D. Shaft 29 has the aforesaid section 30 of reduced diameter and below it another section 31 of still further reduced diameter, the section 31 being carried in hearing 32 having a suitable bushing and 'resting on the base 33 mounted on deck F. The shoulder .between shaft sections 30 and 31 rests on suitable packing on the top of bearing Further the shaft section 30 is surrounded within the loose pinion 22 with suitable packing or bushing, a section of which packing also lies on top of the pinion 22 below the shoulder on shaft 29 between it and shaft section'30. Thus the pinion 20 drives the gear 21 and its connected pinion 22, and rotates same-loosely around shaft 1 section 30. The pinion 22 meshes with and drives a gear wheel 23 which" forms part of the train for driving the capstan and -windlass, and surrounds and is keyed to the hub of a wide toothed pinion 26 which is loose on shaft 27, parallel to shaft 29.

Further the shaft 29 has loose thereon a large gear wheel 24, with which the pinion 26 engages and drives, proper bushings and packing pieces being within the bearing of gear wheel 24 and on top of same, in order to' facilitate the operation. The lower end of shaft 27 revolves in bearing 28,- that is mounted on base 34 on deck F, and a suit able bushing surrounr's shaft 27 in bearing.

28, and within pinion 26, and there is packing between the lower end of pinion 26 and top ofbearing 28. Thus pinioni20 drives gear21 and pinion 22, which drives gear 23 and pinion 26, which drives gear wheel '24. The shaft 27 is the lower end of the shaft 44 which transmits motion through gears 43 and 42 to the capstan shaft 40.

In quite a similar manner, see Figure 2,

the shaft 19 of pump B has a pinion 20" thereon which meshes with and drives a gear wheel 21 secured to pinion 22 that is loose on a part of shaft 29, and pinion 22 engages and drives gear wheel 23 secured to wide pinion 26 loose on shaft that forms lower end of shaft 39, and pinion 26 meshes with and drives large gear wheel 24 loose on shaft 29. The gears 24 and 26 may be locked to their shafts as in the case of gears 24 andSQ... The shaft- 39 drives gear 38 that engagesgear 37 on shaft 35 of cap- 7 Stlll C. Shaft 29 is coupled to shaft 45 by coupling 48 to drive the Windlass D.

I will now explain the devices for locking the Windlass shaft 29 to the gearing so that pump B will drive same and the Windlass; 7 and the means for locking shaft 44 to the gearing so that the capstan shaft may be driven or may be disconnected and *thrown 1 out of action. Windlass and capstan may be driven together or separately.

Keyed to shaft 29 above the loose gear wheel 24 is a horizontal locking head'or Wheel 25.. The upper surface of the outer periphery of gear 24 is-provided with a series of rectangular notches 49, adapted to 35 be entered by a pair of locking block keys 50. These keys are raised and lowered so as to be caused to engage with or be disengagedfrom twoor more of the'notches 49 by means of a ring 51, see Figure 5, which. loosely surrounds a flange 52 on wheel 25 and is kept in place by small plates 53tha't members 24 and 25.- It is also necessary to provide means for locking the shaft 44 and its extension 27 to the loose wide pinion .26. The top of'the pinion is provided with teeth of any desired kind at 57. Vertically adjustable on shaft 44 above teeth 57 is a block 58 that is splined or feathered to the shaft, and has teeth 59'to clutch teeth 57 when block 58 is depressed. A. hand wheel 60 has an internally-threaded hub 61 that screws on a screwthreaded section 62 of shaft 44. The hub 61 connects with block 58 by a ring-63 which enters a groove in the hub but is rigidly screwed .or attached to block 58. Thus by turning handwheel' 60 the block 58 may be raised or lowered and put'into or out of clutch, so as to' connect pinion 26 to the shaft or disconnect it therefrom, and obviously when connection is made the gearing will drive the capstan.
