NAVIGABLE BALLOON.
P tented Oct. 15, 1895'.
UNITED STATES PATENT OFFICE.
WILLIAM NELSON HUTOHINSON, OF EASTBOURNE, ENGLAND.
NAVIGABLE BALLOON.
SPECIFICATION forming part of Letters Patent No. 548,053, dated October 15, 1895'.
Application filed May 1, 1895. Serial No. 547,787. (No model.) Patented in England November 23; 1893, No. 22,483, and June 1, 1894., No. 10,610.
2'0 aZZ whom it may concern.-
Be it known that I, WILLIAM NELSON HUTOHINSON, a citizen of Great Britain, residing at Eastbourne, in the county of Sussex, England, have invented certain new and usef ul Improvements in Navigable Balloons, (patented to me in Great Britain November 23, 1893, No. 22,483, and June 1, 1894, No. 10,610,) and I do declare the following to be a full, clear, and exact description of the invention, such as will enable 'others'skilled in the art to which it appertains to make and use the same,reference being had to the accompanying drawings, and to the letters of reference marked thereon, which form a part of this specification.
My invention relates to navigable balloons, and its objects are to aid the steering by making end propelling-screws turn in a horizontal plane and to keep the skin expanded automatically by means of a loose inner skin or lining at the bottom of the balloon acted upon by springs.
In the accompanying drawings, Figure 1 is a side elevation of a balloon embodying my improvements. Fig. 2 is a detail plan view, on a larger scale, of one of the end propellingscrews. Fig. 3 is a sectional elevation of the same. Fig. 4: shows a modification. Fig. 5 shows the gearing for driving the intermediate screws. Fig. 6 is a cross-section of the balloon, and Fig. 7 is a detail.
The balloon A is of cylindrical shape, since this is the best for carrying the Volumes of gas necessary to float the weight of efficient far-traveling balloons with their indispensable accessories. Even in this form there is a limit to the diameter, but practically none to the length, provided all waving motion in flight be prevented.
Lying within the balloon and lengthwise of it is a tube B, preferably of tough aluminium alloy and about one foot in diameter. It is virtually a backbone and gives the required firmness. The front end of the balloon is covered by a pointed conical prow B, also of aluminium alloy and supported by braces. 17 running from the tube B. This cone pierces the air and prevents the balloon from caving in.
The cars 0, of which there may be any convenient number, are hung below the balloon by means of cords of from the net 0 encircling the balloon. Upright rods D are connected to the backbone B and to the cars by ball'and-socket joints (:1. The sockets are of unusual depth, so that the balls may have a little free play. The cars lie preferably in line, as shown, and on the sides of one or more are horizontal rudders E, by means of which the balloon is made to rise and sink without change of horizontality.
A driving-shaft F runs lengthwise through all the cars and imparts motion to the propelling-screws. Since there is a limit to the diameter of these screws, it is necessary to employ a number of them in a large balloon. The cylindrical shape of the balloon is well adapted to a multiplicity of screws, because they can be arranged one before another along the entire length of the balloon.
The screws G between the cars are provided with short tubular shafts g, sleeved upon the main shaft F. The adjacent ends of cars 0 are held in position by their attachment to the extremities of this tubular shaft g, as shown in Fig. 5. On the main shaft is a bevelgear f, which, by means of an idle-gear 0, drives the screw G. By varying the proportions of these gears the speed of the sc r'ew can be regulated. I
The longer the balloon the greater the difficulty in steering it. Vertical rudders H are provided at front and rear, but they have little influence unless the speed be good, and their tendency is to check the speed. I therefore provide for steering by the leading and rear screws G, which are so connected with the driving-shaft as to be capable of turning to one side or the other in a horizontal plane. This may be accomplished in a Variety of ways. I prefer the construction shown in Figs. 2 and 3, in which the roof and floor of the end cars are extended to form an open chamber or balcony, in the upper part of which is a stationary frame work of bars I,
supporting a set of coned antifriction-wheels K, on which rests a circular platform or turntable L, held in position by flanges on the rollers. A counter-shaft g, carrying the screw G, is journaled diametrically on the turntable and has secured to it a pulley located the belt runs.
increases as the table is turned by the aero nauts, the belt is made elastic, or instead of an elastic belt I may use a slack drivingchain running over sprocket-wheels, for the journal-block f Fig. 3, of the main shaft may be held loosely by upright bolts 3, was
to be capable of slight vertical movement. A link-rod N is then attached by arball-andsocket jOlHCftO IhG under side of the turntable adjacent to the openingthrough which The lower end of the rod is attached bya similar ball-aud-socket joint tothe journal-block f When the table is turned,it raises the journal-block and 'Wlthili] the end of the main shaft, so that the belt always travels in uniform tension.
lo prevent the turn-table fromtilting under the weight of the screw@, HQFOOVB Zis made inthe edge of the rear half of the table, with which engages :a fixed transverse horizontal bar I.
tlt is verydesirable to keep the skin-of a navigable balloon, whether cylindricalor of other shape-constantly extended, however great and sudden may .be alternationsin the bulk of the confined gas. I accomplish this automatically by the following means: {Immediatelyabove the'backbone B, which acts as acondenser, lies horizontally a light Ibasket-workframeO the length of thebaclibone and of a width most suitable for the spring P to push the frame upward bymeans ofthe fork R straddling the backbone B. The
springs are supported and adjusted bynuts s on the lower ends of bolts S, springingfrom the floors of the cars. Inside the bottomof the balloon is a loose lining T, the central part of which rests on a framework 0. The springs keep the lining pushed up against the tension of the gas, soas to yield to any increase in its volume or take up any decrease and thus preserve the shape of the -whilethc space for the propelling-screws is doubled.
