JOHN II. HOSLEY, OF ST. LOUIS, MISSOURI.
PROPULSION OF VESSELS.
SPECIFICATION forming part of Letters Patent No. 571,127, dated November 10, 1896.
Application filed May 18, 1896. Serial No. 592,035. (No model.)
To all whom, it may concern:
Be it known that I, JOHN H. MOSLEY, a citizen of the United States, and a resident of the city of St. Louis and State of Missouri, have made new and useful Improvements in the Propulsion of Vessels, of which the following is a specification.
My invention relates to the propulsion and steering of vessels, and has for its object t0 utilize a screw-propeller in aid of the rudder; and it consists in arranging the screw-propellers so that their axes can swing horizontally, the connecting devices being inclosed in a water-tight casing, as hereinafter described and claimed.
` In the accompanying drawings, which form part of this specication, Figure 1 is a side elevation of a rudder with a screw-propeller mounted therein. Fig. 2 is a vertical section thereof on the line 2 2 of Fig. 1. Fig. 3 is a side elevation, and Fig. 4. is an end elevation,
showing, in addition to the construction of Figs. 1 and 2, a pair of twin screws whose journals oscillate horizontally. Fig. 5 is a vertical side view of the steering mechanism, showing the propelling mechanism in section, such propelling mechanism being the same as in Figs. 3 and 4. with the rudder-screw omitted. Fig. 6 is a horizontal section on the line 6 6 of Fig. 5. Fig. 7 is an enlarged horizontal section of the propelling mechanism and rudder of Figs. 5 and 6 on the line '7 7 of Fig. S, and said Fig. 8 is an end elevation of the rudder and twin propellers.
The rudder 1 is hinged on the hull of the vessel in the ordinary manner and is controlled by the ordinary steering mechanism.
In the form of my invention shown in Figs. 1, 2, 3, and 4. an opening 2 is made in the rudder large enough to accommodate a screw-propeller 3, whose shaft turns in journal-bearings 4, provided therefor on the rudder 1. The propeller-shaft has a bevel-gear 5, which meshes with a like bevel-gear 6 on a collar 7, loosely j ournaled on the rudder-shaft 8. The other end of this loose collar 7 also has a bevel-gear 0, which meshes with a bevel-gear 10 on the engine-shaft or operatively connected therewith.
The operation of the above-described construction is as follows: The motion of the engine-shaft is transmitted to the collar and from the collar to the propeller-shaft- The rudder, and with it the propeller, is controlled by the ordinary steering mechanism independently of the propelling mechanism, as the bevel-gears of the collar permit the propeller-shaft to shift horizontally to any desired angle without affecting the connection with the engine-shaft. As a screw-propeller exerts its force in the direction of its axis, when the axis is inclined to the keel, the tendency is to move the stern of the vessel sidewise' and thus change the direction of the vessels motion. By mounting the propeller on the rudder the steering effect of the propeller is utilized in aid of the rudder and both are controlled by a single ordinary steering mechanism.
The triple screw construction shown in Figs. 3 and 4 consists of the screw on the rudder, as above described, and twin screws whose shafts are mounted in a rotary framework 11, supported preferably on the keel 12. The mounting of the twin screws is best shown in Figs. 5 and 7. Said twin screws 13 are mounted on parallel horizontal shafts journaled in the pivotal framework 11, xed to a vertical shaft 14, adapted to be turned by the steering mechanism, as shown in Fig. 5. The framework 1l, fixed to the shaft 14, turns therewith, and thus the' axes of the propeller-screws change their direction along with the rudder.
A suitable arrangement of the devices for driving the twin screws isl shown in Figs. 5, 6, and 7. The vertical shaft 14 has a loose collar 15 thereon, provided with two bevelgears 16 17, meshing, respectively, with a bevel-gear 18 on the engine-shaft 19 and with a bevel-gear 20 on a shaft 21, journaled in the movable framework 11. This shaft 21 has a gear-wheel 22 fixed thereon, which meshes with gears 23 24. on the shafts of the twin propellers. In order that the dri vin g and connecting mechanism may meet with less resistance, it is inclosed in a water-tight casing. The lower section of this casing is fixed to the keel or otherwise and has its top edge of cir cular form. The upper section is fixed t0 the vertical shaft 11, to move therewith, itslower edge being of circular form to it the top edge of the lower section. The joint between the sections is made water-tight by means of a IOO suitable packing 2G, fitting in annular grooves in the meeting faces of said sections, as shown in Fig. 5. It is obvious that divers changes may be made in the driving and connecting devices, and I do not Wish to restrict' cal shaft having a loose collar thereon provided with two bevel-gears, a bevel-gear on the engine-shaft meshing with one of said gears and a pivotally-mounted framework having one or more horizontal shafts journaled thereon and each carrying a screw-propeller and being connected to and driven by said vertical shaft, and a casing inclosing such connecting mechanism and consisting of two horizontal sections, one of said sections being fixed and the other section being fastened to the vertical shaft and comprising the pivotal framework above mentioned, substantially as and for the purpose set forth.
