Excerpts from the Patent: " . . . Describing in detail what is shown in the drawing, within the fuselage 10,  is placed any desired number of chairs each including a seat or bottom, 11, with sides, 12, and back, 13, the seat on the underside being engageable by an upward and outward expelling device against the action of which the chair is normally held by a releasable latch device, which remains in chair-locking position until the emergency arises for the expulsion of the chair with its occupant from the machine. Such expelling device may consist as shown, of one or more spring or elastic bands or straps, 14, which extend transversely of the fuselage beneath the seat and with their opposite ends secured to the frame work at a sufficiently high point that when the chair is in normal position, the bands are stretched and placed under tension extending beneath the seat and upwards along the sides of the chair. Upon opposite sides the seat engages vertically extending guide bars, 15, over which the seat slides when the expelling device acts and which serves to position the  seat when in normal position for use. Said vertical bars preferably inclined upward and rearward so that when the chair is acted upon by the expelling device, the chair will move not only upward but rearward for the purpose of contributing to the clearance of the airplane by the chair when expelled therefrom . . .

The chair as has been explained is equipped with a parachute 31, the suspending cords, 32, of which are suitably attached to the side and rear edges of the chair seat, 11 and which is so associated with the chair in a folded or collapsed state that when the chair is projected out into the air and begins to descend, the parachute will automatically open. As a convenient way of storing the parachute ready for use, I make the side and back walls of the chair hollow or double to provide a storage space, 33, in which the parachute may be stored. I preferably equip the parachute with a supplemental or auxiliary small parachute, 34, which initiates the removal of the main or supporting parachute. Said auxiliary small parachute, 34, is stored in the upper part of the chamber in the side and back walls of the chair and the outer section of the double wall is provided with perforations, 35, to allow the free and ample flow of air into contact with the auxiliary parachute when the chair begins to descend, to at once force the auxiliary parachute out of the chamber and to initiate the opening thereof. . . ."
