WILLIAM SINGLETON, OF CANTON, OHIO'.

SHIP-VENTILATOR COWL.

Application led October 15,1924. Serial No. 743,752.

To all 'whom t may concern.' ,i

' Be it vknown that I, WILLIAM H. S1NGLE- ToN, a citizen `of the United States, and a resident of Canton, county of Stark, State of Ohio, have invented certain new and useful Improvements in Ship-Ventilator Cowls,

of which the following is a specification.

This invention relates to cowls and more particularly to cowls for Ventilating ships. More particularly the invention relates to mechanism for automatically moving the cowl to maintain the intake thereof toward the wind.`

. Cowls used onboard ship are of very large size and it has' heretofore been the custom to have them provided with suitable gearing by which they might be turned into *y thewind and it is the object of this invention to provide the cowl withmechanism for automatically performing this function. It

vis a further object of the invention to' provide mechanism for rotating the cowl by means of a windmill, located in the cowl and driven by the current of air passing therethrough. i

Other objects and the features of novelty will be apparent from the following descrip tion taken in connection with the acconipanying drawings, of which:

Figure 1 is a vertical section through a ships cowl, embodying my invention;

Fig. 2 is an `enlarged plan view of the rotating mechanismfor the cowl, as seen from the line' 21-2 of Fig. 1, certain parts being Fig; a.

shown in section; i Fig. 3 is a side elevation of the mechanism show n in Fig. 2; I i `Fig; 4 is a section on the lline 4--4 of Fig.V 3;

. Fig. 5 is a development of the surface of thecylindric-al cam constituting one `of the :elements of the mechanism and rig. e is an enlargement of a fragment of Referring to the drawings, indicates a cowl that is rotatable on the ring 11 which is fastened to the ship deck 12 by bolts 13. .Thelower end of the cowl is provided with .an angleJ iron 14.having a horizontal flange that rests upon thefring 11 and this ring is provided with an internal groove 15 with which a series of set screws 16 cooperate to hold the cowl in the upright position. A pipe 17 is arrangedin axial alignment with .the cowl' and is secured tov the deck 12 in any suitable manner as lby means of the'angle .shaft 20.

iron 18 which is secured to the deck by the bolts 13.

The ring 11 is provided with teeth constituting an internal gear 19 arranged coaxial with the cowl and the pipe 17. A vertical shaft 20 is arranged at the center of this internal gear and carries a windmill 21 by means of which the shaft is rotated, the windmill heilig actuated by the air passing downwardly through the cowl. The lower end of the shaft 2O is supported in a bearing 22 and this bearing is supported by the brackets 23 which are secured to the pipe 17. The upper end of the shaft 20 is supported in a bearing 24 on the bracket 25, this bracket having an upturned end portion 26 that is secured to the cowl 10 by bolts 27. A collar 28 is secured on the shaft 20, by a. set screw or in any other suitable manner, and supports the inner end of the bracket 25, the shaft 20 being, in turn, supported by the engagement of the hub of the windmill 21, with the upper end of the bearing 22.

A vertical shaft 29 is supported in the bearing 30, on the bracket 25, and carries at its lower end a pinion 31 that meshes with the internal gear 19. The gear 31 is fixed on the shaft 29 so as to rotate therewith and, on the upper end of this shaft, there is cured a worm gear 32 with which a worm 33 meshes. The worm 33 is secured to the horizontal shaft 34 that is supported in the bearings 35 and 36. A horizontal shaft 37 arranged in axial alignment with the shaft 34, but normally disconnected therefrom, is supported in the bearings 38 and 39, on the bracket 25. On one end of the shaft 37 there is a bevel gear 40 with which the bevel pinion 41, onV the upper end of the shaft 20, meshes, so that the shaft 37 is driven by the A clutch member 42 is secured on the other end of the shaft- 37 and is adapted to be disengaged by the shiftable clutch member 43 that is splined on the end of the shaft 34.

A horizontal shaft` 44 is supported in bearings 45 and 46 on the bracket 25 and has secured thereon the gears 47 and 48. A sleeve 49 is loosely arranged on theshaft 34 and carries a gear 50 which meshes with the gear 48. A gear 51 that is secured to the shaft 37, meshes with an idler gear 52, supported on the stub shaft 53. and this idler gear meshes with the gear 7 so that the shaft 44 and sleeve 49 are driven from the shaft 37.

The sleeve 49 carries aclutchmember 54'C with which the clutch member 43v is. adapted to engage. f i

A cylindrical cam member issplined on the shaft 37 so as to be rotated therewith and yet movable axially thereon and a yoke 56 connects the member 55 with the shiftable clutch member 43 so that the axial movements of the member 55 are transmitted to the member 43 to move the latter from the neutral position shown in Figs. 2 and 3, into engagement with eitherI of the clutch members 42 or 54.

rIwo upright arms I57 are supported on the bracket 25, on opposite sides of the cam member 55 and each of these arms carries two short shafts 58. Each of the shafts 58 carries a member which cooperates with the. cam member 55 and, since the two pairs of these members are alike I will describe the pair on one side of the cam member 55, these being shown at 59 and 60, in Fig. 5. Each of the shafts 58 carries at its outer end an arm 61 and the upper ends of each pair of these arms carry pins 61l which are connected by links l62 so vthat the members 59 and 60 move together.

A'shaft 63 has its lower end journalled in a cross member v64 which connects the ment. Lugs 67 project upwardly from the cross member l64 on opposite sides ofthe yoke 65 and serve to limit the swinging movement of the latter. The shaft 63 projects through v.a bearing 68, on the cowlf10, and carries at its upper end a vane 69 that is arranged 'exteriorly of the cowl and adapted to bezturned by the wind.

. :In the operation of the mechanism, as-

suming that the vparts rare in the position shown in the drawings, with the 'cowl 10 turned into the wind, and the vane 69 standing in line with the direction of the wind, a change of the relation of the cowl, to the wind, either by a turningmovement of the ship or a' shiftingv of the wind, will cause Athe vane 69 to be turned by the wind and this turning movement will be transmitted to the yoke 65 fand, from the latter, through engagement with the pins 61', will cause the cam members 59 and 60 to be swung from the full line position shown in the lower part of-Fig. 5. f The full line position of the cam members .59 ,andl 60 is their normal positionand, since the current of air passing downwardlythrough the cowl will turn the windmill 21 and thus constantly rotate thecam member 55, the members 59 and 60 will move 1n the space between the cams 70,

71, andv 72 and 73, the direction of rotation of the member 55 being' indicated .by the arrow in Fig. 5. Assuming that the turning of the vane 69 swings the members 59 and 60 into the dotted line posit-ion, indicated at 74 in Fig. 5, the cam projection 72 will then engage with the member 60, and since the latter is stationary, the member 55 will be shifted axially to-ward the left so that the cam projection 72 will pass between the members 59 and 60 and the clutch member 43 will be shiftedto the left into engagement with the clutch member 42. The shaft 34 will then be rotated directly by the shaft member 55 continuing, the projection 73 will thenengage withthe member 6() and cause the member 55 to be shifted still further toward the right until the members 59 and 60 are inthe relation, to the member 55, indicated in full linesat the bottom of Fig. 5. Al movement of the vane 69 in the opposite direction will cause the member '55 to be .first shifted toward the rightfand engage the clutch member 43 with the clutch member 54, in which case the motion of the sha ft 37 willbe transmitted through the gears 51, 52, 47, the shaft 44, the gears 48 and 50, and the sleeve 49 so as to rotate the shaft 34 in the opposite direction from that previously described and thus shift the cowl in the opposite direction until the parts are again restored totheir normal position.'

1n the operation of the mechanism the stops 67 limit the turning of the vane 69 so that the cowl will continue to follow the movements of the vane until the latter is in lalignment with thev wind, which will also that changes in the details of construction, 25

described and illustrated, may be made without departing kfrom the spirit of the invention which is described in the appended claims.
