Specification of Letters Patent. Application filed December 11, 1912. Serial No. 736,070. To all whom it may concern: 2'728 are pinions at the ends of said propeller shaft adapted to mesh with: the p1nions 29-430 mounted upon the propellers til-39. which are in turn mounted in the brackets 33--34 upon the upper casing of the a nqaratus. These propellers are adaptedto drive the air downwardly when the motors are in operation. p The beveled pinion 35 upon the engine shaft it will be observed meshes with the beveled pinion 36 upon the shaft 37 which also has a beveled pinion 38 at the opposite extremity, meshing with the beveled pinion 39 upon the propeller shaft 40 carrying the propeller 41 which is adapted to give forward movement to the apparatus. From this it will be seen that the propulsive propeller may be connected up separately and independently controlled from the lifting propellers and may be operated from an engine entirely separate therefrom.
42 is the steering rudder of the apparatus connected by the cable 43 which passes over the pulley 44 controlled by rotating the 0p- Be it known tlratl, AooLr Donner-1, a subject of the Emperor of Austria-Hungary, re siding at the city of New York, in the county of New York and State of New York, have invented certain new and-useful Improvements in Aeronautical Apparatus, of which the following is a specification. reference being had therein to the accompanying dravw ing.
My invention relates to improvements in aeronautical apparatus and has particular reference to a type of aircraft adapted to be lifted as a whole or in part by a lighter than air gas such as hydrogen, and propellers mounted so as to drive the air downwardly.
In the accompanying drawings 1 have illustrated in Figure 1 a vertical longitudinal section of an apparatus illustrating one application of my invention. Fig. 2 is a plan view looking downwardly upon the same. Fin. 3 an end view, partly broken away. Fig. 4 is an enlarged view of some of the details of transmission, and Fig. 5 is a similar view at right angles to Fig. 4 with erators wheel 45. parts broken away. 46 is the elevating rudder connected by G is the outer shell of the vessel provided the cable 47 whlch it will be seen passes beneatlr the operators seat 49 and is attached to the standard 48 of the controlling wheel so that by throwing said wheel away from or in the direction of the operator said elevatinc, rudder is actuated.
In cross section the apparatus presents a substantially triangular appearance with a convex bottom portion of greater area than the upper part. That is to say, when rising, the bottom of the apparatus presents an enlarged surface which serves to ride upon the air as the machine is advanced by the propeller 41, thus assisting the rising tendency of the machine. The air cast down by the propellers iii- 32 is also thrown clear of the body of the machine and rushes beneath the same addinp; to the rising tendency while the with a series of skids such as 7 to give the same resilient support in landing.
8 is an interior deck or flooring provided with suitable accommodations such as the seat 9 for the operator immediately in front of the port or window 10.
lL- il are suitable engines for driving, the propellers.
12 to 15 inclusive are reservoirs, tanks or bags adapted to carry the lighter than air gas such as hydrogen, and as it will be observed are constructed so as to fit within the outer shell or casing (i of the apparatus.
16 is an. interior lining or insulating material beneath the outer casing to insulate the heat of the sun from the gas within the bags or tanks 12 to 15 inclusive, and 17 to 20 in-- elusive indicate suitable partitions for sepaback or top of the machine points upward. .1.'atinp the bags or tanks and whlch, together Of course 1t Wlll be observed that various with the flooring 21 of the upper chamber modifications maybe made without departing from the spirit of the invention as claimed.
1. In an apparatus of the class described, a body portion comprising an outer casing, separate gas containers within the upper portion of said outer casing, a power plant located centrally within the lower part of said outer casing and controlling means and the upper outer casing form hermetically closed chambers for the gas bags.
Referring now more particularly to Figs. 4 and 5 it will be observed that upon the driving shaft 22 of the engine the sprocket 23 is carried provided with the sprocket chain 24 which passes over the sprocket 25 upon the propeller shaft 26 at the top of the within reach of the operator at the forward part of the lower portion of said outer casing, said outer casing of substantially triangular cross section, and propellers at the top of said apparatus upon axes substantially parallel with the outer walls thereof, and means in combination with said power plant for driving said propellers.
2. In an apparatus of the class described, a body portion comprising an outer casing, separate gas containers within the upper portion of said outer casing, a power plant located centrally within the lower part of said outer casing and controlling means within reach of the operator at the forward part Washington,
of the lower portion of said outer casing, said outer casing of substantially triangular cross section, propellers at the top of said apparatus upon axes substantially parallel with the outer walls thereof, means in combination with said power plant for driving said propellers, and a propeller at the stern of said apparatus in combination with steering and elevating means therefor.
In testimony whereof I ailiX my signature in presence of two witnesses.
