Specification of Letters Patent.
Patented Mar. *7, 1911.
Application filed April 7, 1910. Serial No. 553,917.
T 0 all whom it may concern.
Be it known that I, HENRY MITCHELL, a citizen of the United States, and a resident of St. Paul, in the county of Ramsey and State of Minnesota, have invented a new and Improved Flying-Machine, of which the following is a full, clear, and exact description.
This invention relates to an improvement; in flying machines, and particularly to means for automatically maintaining the equilibrium of the machine, without the necessity of any physical or mental effort on the part of the operator.
An object of this invention is to provide a device which will be simple in construc tion, inexpensive to manufacture, light in wei ht and ositive and nick in its 0 eration.
A further object of this invention is to provide 'an automatic equilibrium control, for manipulating planes or portions of planes operated by a pendulum member.
These and further objects, together with the construction and combination of parts, will be more fully described hereinafter and particularly set forth in the claims.
Reference is to be had to the accompanying drawings formmg apart of this specification, in which similar characters of reference indicate-corresponding parts in all the views, and in which- Figure 1 is a front view in elevation, showing the flying machine in a normal, horizontal position; Fig. 2 is a view similar to Fig. 1, showing the flying machine tilted to one side, with the equilibrium planes warped or swung to regain the normal, horizontal position; Fig. 3 is a vertical section through one form of the controlling mechanism; Fig. 4 is a detail view of the pendulum seat, which may be applied to cit-her form of the device; Fig. 5 is a top plan view of the pendulum-seat as applied to the form illustrated in Figs. 1, 2 and- 3; Fig. 6 is a detail view in elevation; showing another form of the controlling mechanism; Fig. 7 is a horizontal section. on the line 7- of Fig. 6; and Fig; 8 is a vertical section disclosing details of the. form shown in Figs. 6 and 7.
Referring more particularly to the separate parts of the device, 1 illustrates a suitable frame, on which are provided one or more supporting planes 2 of any suitable light structure adapted to support the flying machine in air. The sides of any or all of these supporting-planes. 2 may be extended to form equilibrium-controlling planes 3 and 3, or these planes may be formed separately and pivoted in any well known manner to the frame 1. For the purpose of manipulating the planes 3 and 3- in an automatic manner without the necessity of the operator exerting any mental or physical effort to control the same, there is provided a pendulum member 4, which, while it may be actuated solely by its own weight, preferably is provided with a seat 5, so as to support the operator and utilize his weight toobtain thecontrolling force necessary to manipulate the planes 8 and 3. The memher, 1 is pivotally connected in any well known manner to an intermediate frame 6, which may form part. of the frame 1, and is preferably rigidly connected to the flying machine, as by means of a pin 7.
Extending from each side of the pendulum member 4, beyond the frame 6, there are V 4, dueto the pitching and tossing of the fly-- ing machine in the direction of its flight, and to very slight side tilting.
For the purpose of correcting the-larger tiltings of the flying machine to one side'or the other by manipulating the planes 3 and 3, the relative movement of the pendulum member 4 with respect to the flying machine as a whole, or the frame which represents a part of the flying machine, there are provided connections between the pendulum member 4 and the planes 3 and 3. These connections may be of any suitable form, andtwo forms are here illustrated. In the form illustrated in Figs. 1 to 5, the-bar 9 is arcuate in shape, and formed with rack teeth 10on its upper surface, which are enis provided a pair of flexible connections 13' and 14, which extend over suitable guide pulleys, indicated at 15, to the lower and upper sides of the planes 3 and 3 respectively. From the opposite of the drum 12, there also extends a pair of flexible connections 16 and 17, which also extend. over suitable guide pulleys, indicated at 18, to
the upper and lower sides of .the planes 3 and 3', respectively. It will thus be seen that when the flying machine, as a whole, tilts to one side or the other, the pendulum member or seat 4 will tend-to maintain a normal vertical position, so that there will be a movement of the pendulum member and the flying machine which will shift the rack 10 so as to rotate the pinionor gear 11 and the drum 12, thereby tilting up the plane 3 or 3 on the side of the flying machine which is lowered, tending to raise this side to its normal position on a level with the opposite side, and depress the equilibrium plane 3 0r 3 on the side whichhas been abnormally raised, so as to bring it down to a level with the'opposite side.
In the form illustrated in Figs. 6 to 8, the parts are the same as those in the form just described, and are indicated by the same characters, with theexception that theme'ans for operating the'flexible connections 13, 14, 16 and 17,. from the pendulum member 4, is somewhat different. In this case, the bar 9 is not provided with the rack formed with the teeth 10, but engages the frame 6 as a clamp, for-the same purpose as in the other form; The flexible connections 13 and 14 in this case extend'over suitable guide pulleys 19'and 20, through. an opening 21 in the frame 6, where. they are connectedto the farther side of the pendulum member 4 at 22,-asis more cle'arly'illus'tra'ted in'Fig. 7. The flexible connections 16 and'17 also e'xtend over suitable guide pulleys 23 and 24 through the. o ening 21, where they are also connected to t e opposite side of the pendulum' member 4 at 25. It will again be seen in this case that the relative swinging movement of the frame of theflying machine and the pendulum member 4, due to'the abnormal tilting of the flying machine to one side or the other,- will manipulate the planes} and 3 to raise the equilibrium planeon the depressed side, and also the equilibrium planeon the raised side, soas' to counteract each side. of
the effect of the tilting and bring the flying machine to a normal horizontal position.
The operation of the machine will be' readily understood from the above description.
