annouann.

To all whom it may concern:

Be it known that I, J GABRIEL Rncmmo, citizen of the Re ublic of Panama, residing at the city of anama, in the county of Panama and State of Panama, have invented new and. useful Iin rovements in Aeroplanes, of which the 0 lowing is a specification.

This invention relates to improvements in aeroplanes, and its object is to provide an aeroplane which embodies a plurality, preferably a pair, of superposed aeroplane units, each comprising a complete gliding structure with its power plant, which units are rigidly-connected for conjoint operation to provide a double-decked machine, whereby great speed and radius of travel may be obtained, while'in the event of the stoppage of the power plant of either unit the power plant of the other unit will maintain the machine in flight.

A further object of the invention is to provide a novel arrangement of'tlie superposed units whereby increased driving power and carrying capacity, together with a reater stabi ity, will be obtained.

still further object of the invention is to provide a double-decked aeroplane of thecharacter described in which the power plants 1 may be separately controlled, while the steering elements "of the units will oper ate in unison for uniform control in steering and balanclng actions. 7

The inventlon consists of the features of construction, combination and arrangemepit of parts herein fully described andclain e reference being had to the accompanying drawings in which gear.

In carrying my invention into pr'actice,I

provide a pair of superposed aeroplane units 1 and 2, each of which is complete in itself with the exception of the use of launching and alighting gear upon the upper unit 2 the lower unit 1 being shown as provide in the present instance with launching and alighting gear in the form of cushioned wheels 2 work, may be employed.

, but it is to'be'understood that any Specification of Letters Patent. Patented July 16, 1918,

Application filed-Hay 13, 1916. Serial No. 97,898.

suitable type of launching and alighting gear or any suitable type of hydroplane surface, or a combination for land and water Each unit land 2 disclosed in the present instance is of the monoplane type and comprises a gliding structure composed of abody 3, which may beveither in the form of a fuselage or a naoelle, but which is shown in the present instance as of nacelle type and provided with-a cock pit or compartment 4 for the reception of the pilot or aviator and passenger or passengers, if any. This part may be, and preferably is, of dream line form and is provided at the rear end of its tail portion with a combination vertical rudder 5 and horizontal rudder or elevator 6.

The bodies 20f the respective aeroplane units are rigidly connected and held in superposed relation by intervening connecting elements of any suitable construction, which are herein shown in the form of a framing 7 of suitable vertical bars, cross bars and reinforcing wiring. The units are coextensive in dimensions, but the lower unit preferably has its forward end extended to a point sufficiently in advanceof the forward end of the upper unit to provide free tractor propeller clearance without the necessity of spacing the units to an objectionable de gree. This arrangement also gives the machine two centers of gravity and pressure,

one in rear of the other, and a mean center of gravity and premure at a point between the two, by means of which the balancing efiiciency or stability of the machine is greatly increased.

The supporting surface of each aeroplane unit consists as usual in laterally extending wings 8,. which as set forth are of the monoplane type, and may have any suitable lifting curvature. For the'purpose of afl'ordin communication between the two cock pits o the machine, I preferably form a part of the framework 7 so that it provides a ladder 9, for convenient ascent or descent, 'so, that in 1 the event ofdamage-to the power plant or controls of the Ulllt directly carrying the e other pilot, he may pass therefrom to t unit in aquick and safe manner. Sets of control wires or cables 10 and- 11 lead from unison, so that both horizontal rudders or both vertical rudders may be simultaneously erated from either of the cock pits or ilots compartments.

Each unit is provided with its own power plant including a motor 14 and a tractor propeller 15, the propellers of the respectiye units being arranged to operate one above and in rear of the other, so that proper clearance will be obtained and any interference or workin resistance in the operation of the propel ers avoided, The operation of the propellers in diflerent yertlcal planes provides for the lifting portions of their thrust being at like distances from the centers of gravity and pressure of the re spective uints, by means of wh ch an eflicrent balance of the machine upon its supporting bank of air will be obtained. It will be evident from the foregoing de: scription that by providin the connected units, arranged as describe a machine of great speed and lifting power is obtained, since multiplied driving ower will be ob tained. *Eor reasons state a machine ofsuperior stability is also roduced, and, as the cock pit and other portlons of the body of one of the units may be employed strictlyfor the carriage of fuel or su plies, the cruising radius of the craft wil be greatlyincrease'd over the machine of ordinary construction.

Inasmuch as the steering gear of both units ifiay be controlled in unison, it willbe understood that the machine may be steered, balanced and maneuvered wit great ease and facility. Furthermore, in the event of the derangement of either power plant or set of steering controls, the remaining power plant or steerin controls may be employed to maintain flig t and stability. 'o

I claim:

1. A flying machine including a pair of rigidly connected, superposed aeroplane units, eachhaving its own power plant, a companion way connecting said units, and means for controlling and steering the machine from either unit.

2, A flying machine including a pair of rigidly connected superposed aeroplane units, each comprising a gliding structure units, each comprising a own power plant and steering gear, an duplicate controlling devices u on. the respective units for operating sai steering gear.

5. A flying machine comprising a pair 'of rigidly connected units, eachhavin its own power plant and steerin gear, eac power plant including a forwari i tractor propeller, said units havlng their bow portions arranged one in rear of the other.

A flying machine comprising a pair of superposed aeroplane units, each having a pilots compartment, a framing rigidly conhecting said units and including a companionway connecting said compartments, prolling mechanism upon each unit steering evices upon each unit, connected tor movement in unison, and controlling devices in the respective pilots compartments for controlling said steering devices.

7:. A flying machine including apair of rigidly v connected, superposed aeroplane units, each having its own power plant, sets of steering and stabilizing devices upon the respective units, and means for controlling the same from either unit.

8. A flying machine including a pair of rigidly connected superposed aeroplane liding structure of the monoplane type, and each having its own power plant, steering and stabilizin elements upon the respective units, and means for controlling the same from either unit.

In testimony whereof I, affix my signature in presence of two witnesses.
