PROPELLER.
SPECIFICATION forming part of Letters Patent No. 534,518, dated February 19, 1895.
Application filed December 30,1892. Serial nt45 fl82- No m d l- To all whom it may concern.-.
Be it known that I, LORENZO J ULIA Y Pure,
a subject of the. King of Spain, residing at. Guayaquil, Ecuador, have invented a new and for its object to provide a propeller of simple and durable construction and which may be .located almost entirely within the hull of a vessel, thereby rendering it readily accessible if repairs are to be made.
Another object of the invention is to pro-.
vide a cylindrical propeller adapted to propel a vessel by displacement of the water at the stern thereof.
A further object of the invention is to provide a cylindrical propeller having the same weight as the water-to be displaced, thus requiring applied power to drive it in one direction only, an outward direction, it being returned when pressure is removed from its rearward path, by the action of the water in the rear, and thus great economy in applied power is obtained.
The invention consists in the novel construction and combination of the several parts, as will be hereinafter fullyset'forth, and pointed out in the claims.
Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar letters of reference indicate corresponding parts in all the views.
Figure 1 is a partial side elevation of a vessels hull, a portion being broken away illus- In carrying out the invention two propel lers A, are ordinarily employed,and they are of the rudder. both ends, and is considerably shorter than rical area may be obtained with the least possible weight.
Each propeller is adapted to move in a stuffing box B, located around an opening made in the counter of the vessel. The openings are so placed at each side of the rudder G that when the propellers are forced outward they will not in the least interfere with the action The stuffing box is open at the propeller, so that the major portion of the latter will be exposed and accessible from the interior of the vessel when the propeller is in the inner position (Fig. 2) while during the outward movement the propeller will project approximately to the same extent into the water at the rear of the stuffing box.
In front of each stuffing box B a cylinder D is properly supported within the vessels hull,
the cylinders being of any desired size, and
in each cylinder a piston head D, is held to travc1,,the piston head and the propeller being connected by a rod 01, or its equivalent. The length of each cylinder and the length of its piston rod .is preferably,substantially the same, and the distance between the-outer ends of the cylinders and the outer edges of the openings surround ed by the stuffing boxes '13 is approximately of the same length as that of the propeller. .Steam is employed to move the piston head, and is admitted only in front the vessel ahead, whilewhen the steam is discharged from the cylinder D, the hydrostatic pressure exerted by the water will force the propeller to travel forward within its casing until the piston head reaches a point where it is to be again acted upon by the steam.
Owing to the fact that the propeller is of the same weight as the water it displaces, it will have a very easy motion, as it will practically have no tendency either to rise or to lower. The friction between the propeller and the stufiiing box will thus be reduced to a minimum, as the stuffing box will not be required to act as a support for the propeller, and the wear of the stuffing box will be uniform.
It will be observed that the steam is used only to force the propeller outward, the water upon which the propeller acts serving to properly return the propeller. By reference to Fig. 2 it will be seen that the front head of the piston D forms a stop to limit the forward movement of the propeller, when its rear end is essentially flush with the rear face of the stuffin g box.
Stay plates or bars E and E are placed around the outer edges of the openings through which the propellers move, as shown in Fig. 3, in order to strengthen them; and face plates may also be employed for the same purpose.
It will be observed that all of the propelling mechanism is located within the hull, and is therefore readily accessible in the event that repairs are needed.
The length of stroke of the piston will be calculated with relation to the displacement of the boat and the motive power employed.
A propeller constructed as above described is not only simple, durable and effective, but it is likewise economic in its construction and provides for economy of steam,while the action of the propeller is powerful and direct.
Having thus described my invention, I claim as new and desire to secure by Letters Patent 1. In a propelling mechanism for vessels, the combination with the hull having an opening provided with a stuffingbox open at both ends and having a bore of uni orm di ameter, and a steam cylinder disposed within the hull a predetermined distance from the box, of a propeller member held to snugly fit the aforesaid stuifing box andhaving a piston rod connected therewith operating in the cylinder, said rod earryinga piston, such piston cylinder, the hull stuifing box and the propeller member being arranged relatively, whereby the piston will form a stop to limit the outward thrust of the propeller member, and the major part of the sliding surface of such member will be exposed within the hull when the said member is forced to its innermost position.
2. The combination with the hull having an opening, and a stuffing box therein, said stuffing box being open at both ends, of a propeller of uniform cross section fitting tightly into said stuffing box, but of greater length than the same, said propeller being adapted to reciprocate in the stufling box in such .3 mmner as to alternately project from the outer end of the stuffing box to propel the vessel, and then project inwardly beyond the inner end of the stuffing box to expose the sliding surface of the propeller, whereby the said surface is rendered readily accessible from the interior of the vessel, substantially as described.
