AIR-SHIP.

rBPECIFICATION forming part of Letters Patent No. 668,375, dated February 19, 1901.

Appllcation filed August 11, 1898. Serial No. 688,363. (No model.)

To a, whom it may concern.

Be it known that I, ARISTAROHUS F. HUB BARD, of Simmler, in the county of San Luis Obispo and State of California, haveinvented a new and Improved Ail-Ship, of whichthe following is a full, clear, and exact description.

My invention relates to an improvement in flying-machines, and comprises thenovel fea-.

iures hereinafter described and claimed.

Reference is to be had to the accompanying drawings, forming a part of this specification, in which similar characters of reference indicate corresponding, parts in all the figures.

Figure 1 is a side elevation and partial section of my device. Fig. 2 is a top plan view with the body partiallyin section, and Fig. 3 is a detail showing in section the pivotal connection of the frames carrying the propeller mechanisms with the body of the air-ship.

A suitable body or house is constructed, the upper portion of which forms a gas-containing chamber A, which acts as a balloon to support the major portion of the weight in the air. This chamber may be made of such a size and material as is found to be best adapted to the purpose. It mayin some cases be relied upon to supply the greater part of the lifting power and in other cases only a small part, the remainder being supplied by the mechanism installed in the lower cornpartments. Beneath this floating chamber is a chamber A, which contains the machinery for operating the airship, together with the passengers and freight. Extending through the lower chamber are two transverse and horizontal shafts B. I have herein shown only two shafts, although a greater number maybe used, if desired. These shafts project beyond the sides of the body of the ship and are adapted for connection with the propellers, by which the raising and lowering of the ship and its propelling are efiected.

Where the shafts pass through the side walls of the body, they are surrounded with sleeves O5. (Shown in detail in Fig. 3.) These sleeves are again mounted in bearings a, which are secured to the body of the ship. To the outer ends of the sleeves O are secured rings 0, within which are secured propellerwheels P. These propeller-wheels are mounted upon vertical shafts, which are secured in 'justed so as to facebackward.

suitable bearings carried by the ring 0, said bearings being supported in cross-bars P.

Upon the vertical shaft of the propellerwheel is secu red a bevel-gear H,which meshes with the bevel-gear G, secured to the horizontal shaft B. By means of this connection the propeller-wheels maybe revolved by rotating the shafts B. The shafts B are rotated by means of any suitable motor located within the body of the ship and connected with the shafts. This motor is shown at F. Upon the outer ends of its shaft are shown pulleys F, which carry belts F connecting them with pulleys F mounted upon the shafts B.

Upon the inner ends of the sleeves O are secured cranks C The cranks upon the same side of the ship are connected by means of rods or bars D, so that they will all move together. The cranks upon opposite sides of the ship are connected, so as to move together, by means of a bar 0 which rigidly connects two opposite cranks or the two cranks upon one shaft. One of the cranks C has a wormgear E secured thereto. A worm E is mounted upon a shaft E and meshes with the wormgear E. The shaft E has a hand-wheel E mounted thereon, by means of which the position of the cranks may be adjusted and the position of the propeller-wheels controlled.

. In rising from the ground the propellerwheels would be adjusted horizontally unless it was desired at the same time to progress forward or to the rear. If it is desired to progress forward, the propeller-wheels are ad- If desired to progress to the rear, the p ropeller-wheels are turned so as to face forward. The amount of turning will seldom be sufficient to throw the propellers into a vertical plane, although this might be done in some cases. Ordinarily the propellers would be adjusted in an angular posit-ion facing to the rear and downward or to the front and downward.

Upon the upper portion of the body of the ship are two masts J. A single mast might in some cases be sufficient and answer all purposes, although two masts are preferred. In the upper portion of these masts are mounted rollers J adapted to receive the guy-rope for controlling the air planes. Pivoted to the upper portion of the ship are two air planes I. These air planes are pivoted by their edges which are nearest to the center of the ship, so that they may be swung upward or downward, as indicated by the solid and dotted lines in Fig. 1. A rope J passes over the pulleys J upon the mast and is attached to the outer edges of the body of the air planes I. The ends of the rope are then conducted into the ends ofthe air-ship and pass over guiderollers J They are then cond noted to drums K, mounted within the ship and by means of which either end may be run out or drawn in, as desired. The connection of the ends of the rope to the drums is opposite, so that when one end is drawn in the other end will be run out. By this means the air plane upon one end of the ship may be thrown downward and the air plane upon the other end thrown upward, thus placing both in the same angular position. These air planes extend beyond the sides of the ship and are to be used for controlling the vertical position of the ship. When it is desired to elevate the ship while in motion, the air planes will be thrown into such a position that their forward edges are higher than their rear edges. The forward motion of the. ship will thus tend to raise it. When it is desired to descend, the

' air planes will be oppositely adjusted.

will provide for lateral steering of the ship. 40

The lower portion of the body of the ship or the lower chamber A has its bottom and side walls made water-tight for some distance upward from the bottom, so that the ship may float upon any body of Water upon which it may alight.

Having thus'fully described my invention, I claim as new and desire to secure by Letters Patent- An air-ship having an air plane adapted to transverse pivots at each end of the ship, the pivot being located at the edge nearest the center of the ship, a mast between said air planes, a rope extending over the mast and attached to the outer end edges of both air planes and then extending beneath the air planes and within the bodyof the ship, and a drum having the ends of the rope attached thereto, and provided with means for turning whereby the planes are swung oppositely and their angular directions are maintained uniform, substantially as'descri'bed.
