MAURITZ ENGSTROM, OF GLAM FALLS, WISCONSIN.
.AIRSHIP.
To all whom it may concern:
Be it known that I, MAURITZ ENGSTROM, a citizen of the United States, residing at Clam Falls, in the county of Polk and State of WVisconsin, have invented certain new and useful Improvements in Airships, of which the following is a specification, reference being had therein to the accompanying drawlng.
This invention relates to improvements in air-ships.
The object of my invent-ion is to provide an air-ship in which the ship proper consists of an elongated cylindrically shaped vessel, being somewhat conical in form and having pivotally suspended from its under side a car for carrying the operator and a mechanism for generating the power.
Another object of my invention is to provide a ship proper with a propelling mechanism, the same being of such a shape as to convey the power fluid by means of which the said propellers are caused to rev lve.
A still further object of my invention is to provide the ship proper at its forward and at its rear ends with a drawing and pushing propeller, each adjustable on a vertical pivot, whereby the ship may be steered.
A still further object of my invention is to provide a ship of-this character having certain details of structure hereinafter more fully set forth.
In the accompanying drawingsFigure 1 is an enlarged side elevation of an improved air-shlp showing the ship proper and the car in a parallel position. Fig. 2 is a vertical transverse sectional view of the ship proper taken on the line 22, Fig. 1. Fig. 3 is an enlarged vertical sectional view through the center of one of the vertically disposed propellers, showing the means by which the blades are feathered.
Referring now tothe drawings, 1 represents a cylindrical vessel forming ,the ship slightly conical, as indicated at 1.
proper and which has its forward end The rear end has a straight Vertical wall 2', as clearly shown in Fig. 1 of the drawings. The conical-shaped forward portion of the ship is for the purpose of reducing the friction of the machine as it passes through the air.
Mounted upon the upper end of the shi proper, are series of motors 2 carrying vertically disposed shafts 3, having at their upper ends the lifting fans 1. I have shown four Specification of Letters Patent.
Application filed November 1, 1910.
Patented Dec. 19, 1911. Serial No. 590,229.
of these lifting fans, but it is understood that any desired number may be used. These motors 2 receive the ower from a pipe 6, communicating with the ship proper and having branch pipes leading to the several motors. The blades 4: of the fans 1, are made somewhat crescent-shaped in trans verse cross-section, as shown in Fig. 1, which is essential so as to catch as much air as possible and exert the greatest amount of liftin power when revolved.
ounted upon the upper end of the ship proper, between the two forward fans and between the two rear fans are two motor propelled shafts 8 carrying a propeller upon each end, and these fans are identical in structure. The motors 9 from which the shafts 8 derive their power are supplied with air through a suitable pipe connected to the main pipe 6, and said motors are adapted to revolve the shaft 8 in a clockwise direction. The shafts 8 extend out beyond the sides of the ship proper and are supported by suitable brackets 13'. Carried by the bracket 13 is a sleeve 13. upon which is mounted a fixed hub 14. The shaft 8 extends out through the sleeve 13, and through the hub 14, and has mounted thercon the hub rim 1|. This hub rim 11 has a series of propeller blades 10, rotatably mounted therein, the inner ends 12 of said propeller blades are provided with cranks 12 which extend into a spiral groove 15, in the hub 14:. From this description, it will be seen that the sleeve 13 is held against rotation and the rotation of the shaft 8 causes the rim 1 1 to revolve carrying the propeller blades. The propeller blades are caused to oscillate owing to the crank 12', traveling in the groove 15 of the hub 14. The relative arrangement of the hub 1a and the rim 11 is such that the propeller blades feather so that the propellers exert only a lifting power. These vertically arranged propellers not only exert a great lifting power, but they are also designed to thoroughly cut up and destroy as much as possible the thrust of the descending air from the vertical lifting fans and thereby prevent the downward draft caused by said fans to unbalance the machine and thus cause a better balanced machine.
Pivotally attached to the bow end of the cylinder 1, is the motor driven propeller shaft 15 which motor 15 derives its power from the reservoir 1 through the pipe 6 and passing operates the drawing or sucking propeller 16. This shaft 15 with its motor 15 being pivoted at 17 is held in position laterally by suitable steering chains or lines 18 which run through suitable sheaves 19 and 20 mounted upon the side of the cylinder 1 and lead to the operating drum in the car which will be more fully explained later.
At the stern of the cylinder 1 is pivoted the motor driven propeller shaft 21, which is identical in every respect with that of the bow propelle'nexcept that the blades of the after propeller are arranged to thrust or push instead of pull as in thecase of the bow one, and both of said,propellers unite in propelling and' steering the ship. The shaft 21 and its motor are held in position by means of the steering lines 22 pass ing through sheaves 23 and 24 to the operating drum, the steering lines on the opposite side of the ship to that in the drawings through similar sheaves to the opposite side of the steering drum as is c0mmon in such practice.
25 represents the car, which as before stated, is pivot-ally suspended from the under side of the cylinder at 26 in the bracket 27 securely fastened to the cylinder 1, the car being preferably rectangular in cross section and flat bottomed.
28 is a tilting rod pivoted in the bracket 27 just above the pivot 26, the opposite ehd of which rod is attached to the quadrant lever 29 in the car, whereby the horizontal position of the car in relation to the locomotive may be readily changed as required in ascending and descending.
The forward end of thebottorn of the car is tapered upward and slightly concaved as shown at 30, this being for the purpose of more easily surmounting the air and the lower corner of the stern is preferably slightly rounded.
Within the car and in any convenient location is the steering wheel 31 mounted upon the shaft 32, which carries the drum 33- around which the steering lines or cables from the bow and stern propellers are wound and operated, which in turn determines the position of the same and guides the ship laterally.
34 represents an electric storage battery which-furnishes power to the electric motor 35, which in turn operates the air compressor 36, whereby compressed air is supplied to the reservoir or cylinder 1, through the flexible pipe 37.
Suitable cable operated spring valves 38 are interposed between the various motors and the airsupply pipe 6 so that the motors may be governed by the operator from the car 25, and for which purpose the various cables 39 lead through suitable sheaves 40 and down through a verticaltunnel or tube 41, through the cylinder 1 to a set of the air motors which I have illustrated are of the type used for drilling and such work, and I do not wish to limit myself to details in construction, as these will doubtlessvary greatly under different circumstances.
