MARINE PROPULSION APPARATUS.
To all whom it may concern.-
Be it known that I, Emma F. Been, a c1t1zen of the Unlted States, residing at Chicago, in the county of Cook and State others skilled in the art to which it apper-' tains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.
This invention relates to new and useful improvements in propulsion apparatus for ships and the object in view is to produce a simple and eiiicient device of this nature so arranged that great speed may be obtained with the expenditure of a minimum of power and comprises various details of construction and combinations and arrangements of parts which will be hereinafter fully described, shown in the accompanying drawings and then specifically defined in the appended claims.
I illustrate my invention in the accompanying drawings, in which Figure l is a side elevation of a portion of a ship showing the application of my invention thereto. Fig. 2 is an enlarged detail view of the propelling apparatus. Fig. 3 is a top plan view of the same and a portion of the ship to which the apparatus is applied. Fig. 4 is a detail sectional view on line 4ld of Fig. 2, parts being in elevation. Fig. 5 is a detail sectional view through a buffer member, and Fig. 6 is an enlarged detail perspective of one of the propelling blades.
'Reference now being had to the details of the drawings by letter, A designates the hull of a ship which is broken away to show the application of two sets of the propelling apparatus, it being understood that any number of similarly constructed sets may be employed when desired and positioned at different locations along the sides of the vessel.
In Fig. 3 of the drawings, I have shown a driving shaft B mounted in the bearings B and to which shaft a disk C is fixed, carrying an eccentrically mounted pin D to which one end of the pitman E is pivoted, the other end being fastened to a crank shaft F which is bent at a right angle. Said Specification of Letters Patent.
Application filed August 25, 1913.
Patented Apr. *2, 1914. Serial No. 786,513.
shaft F has a reciprocating movement in the curved slot H formed in the side of the ship, as shown clearly in Figs. 1 and 2 of the drawings. The shaft F extends downwardly outside of the ship and is provided with two elongated slots, designated by letter F, and the shaft has pivotal connection with a pin K projecting from the side of the ship and is suitably reinforced by the truss rods I.
Mounted to have reciprocating movements in the guide members N, secured to the side of the ship, are the rods 0 which are fas tened to the opposite ends of a rack Q, a top plan view of which is shown clearly in F 8, and which rack has a series of blades It, details of which are shown clearly in Figs. l and 6, each being provided with integral eyes R, pivotally mounted upon the rod R which in turn is journaled in the opposite sides of said rack. An anti-friction roller R is journaled upon a pin R carried by the rack and is adapted to engage and have a play in the slot F as the shaft rocks upon the pivot K. Projecting from the opposite sides of said rack are the bent bars J, which are connected at their lower ends by means of the cross bars J, against which the blades are adapted to contact to limit their movements in one direction. Each blade has an integral lug R projecting centrally from the upper edge thereof and said lugs are pivotally connected through the medium of the pins S with a bar S. F'astened to the side of the vessel are the casings T, one of which is shown in longitudinal section in Fig. 5, which have open ends T and a coiled spring T is mounted within each casing and bears one end against the inner end of the casing, while its other end is fastened to a plunger T positioned in the path of the end S of the bar S and against which plunger said end S is adapted to contact when the rack has nearly approached its forward limit, the purpose of said springpressed plunger and bar S being to throw the propelling blades back to their normal vertical positions after the blades have feathered in their forward movement and to throw the same in position to impinge against the water as the series of blades are thrown back as the rock shaft tilts upon its pivot K.
It will be noted that the propelling blades are arranged in series, one series piv otally connected upon either side of the pivotal connection of the shaft F with the side of the ship and that, when one series goes forward in the rocking of said shaft, the other series will move in the opposite direction, one series of blades feathering as they move forward while the other series is exerting a propelling action against the water.
While I have shown two sets of propelling blades upon one side of the boat, it will be understood that as many sets may be employed as may be desired and distributed at intervals along the opposite sides of the ship and connected in any suitable manner to the source of power within the latter.
By the provision of a propelling apparatus made in accordance wlth my lnvention, it will be noted that a powerful propelling agency is alforded which will cause the ship to be driven through the water at a great speed and with a minimum of friction,
What I claim to be new is:
1. A marine propulsion apparatus for boats comprising series of rock shafts pivotally mounted upon the sides of the boat, racks having sliding pivotal connection with said shaft upon either side of its pivotal point, feathering blades pivotally mounted upon said racks, means for rocking the shaft, and means for returning the feathering blades to their normal positions as they approach their limit in one direction, as set forth.
2. A marine propulsion apparatus for boats comprising series of rock shafts pivot-- ally mounted upon the sides of the boat, racks having sliding pivotal connection with said shaft upon either side of its pivotal point, feathering blades pivotally mounted upon said racks, means for rocking the shaft, a longitudinally movable bar with pivotal connections between the same and said blades, and a buffer against which said rod is adapted to contact, as set forth.
3. A marine propulsion apparatus for boats comprising series of rock shafts pivotally mounted upon the sides of the boat, racks having sliding pivotal connection with said shaft upon either side of its pivotal point, feathering blades pivotally mounted upon said rack, means upon the latter for limiting the movement of said blades in one direction, a bar having pivotal connection with the blades, and a buffer against which said bar is adapted to contact to return the blades to normal positions as the rack approaches its limit in one direction, as set forth.
4. A marine propulsion apparatus for boats comprising series of rock shafts pivotally mounted upon the sides of the boat,
' racks having sliding pivotal connection with said shaft upon either side of its pivotal point, feathering blades pivotally mounted slots in the side thereof, a rock shaft movable through and guided by said slots, a pivotal pin upon the side of the ship upon which said shaft ispivoted, racks having sliding pivotal connection with said shaft, a series of blades pivotally mounted upon the rack, means for limiting the movements of the blades in one direction, a bar pivotally connected to said blades, and a buffer against which the bar is adapted to contact to cause tions after they have been feathered, as set forth.
6. A marine propulsion apparatus comprising, in combination with a boat having slots in the side thereof, a rock shaft movthe blades to return to their normal posiable through and guided by said slots, a
pivotal pin upon the side of the ship upon which said shaft is pivoted, racks having sliding pivotal connection with said shaft, a series of blades pivotally mounted upon the rack, means for limiting the movements of the blades in one direction, a bar pivotally connected to said blades, said bar haw ing elongated slots, and anti-friction rollers carried by the racks and movable within said slots, as set forth.
7. A marine propulsion apparatus comprising, in combination with a boat having slots in the side thereof, a rock shaft movable through and guided by said slots, a
pivotal pin upon the side of the ship upon which said shaft is pivoted, racks having sliding pivotal connections with said shaft, a series of braces fastened to said racks and having each a cross-piece forming a stop, a series of blades pivotally mounted uponthe racks and having integral lugs, a bar to which said lugs are pivoted, a spring-pressed plunger and a casing in which the same is mounted and against which plunger said bar is adapted to contact as the rack approaches its limit in one direction, as set forth. r
In testimony whereof I'hereunto affix my signature in presence of two witnesses.
