Irving Air Chute Co. v. Russell Parachute Co., 41 F.2d 387, 5 U.S.P.Q. (BNA) 290, 1930 U.S. Dist. LEXIS 2144 (D. Del. 1930).

Opinion

MORRIS, District Judge.

Three patents relating to parachute packs are here in issue. In each Floyd Smith is the patentee. All are owned by the Floyd Smith Aerial Equipment Company, one of the plaintiffs. The other plaintiff, Irving Air Chute Company, Inc., holds a license thereunder that is exclusive save for a nonexclusive license to the United States. Russell Parachute Company, the defendant, manufactures a parachute pack which, plaintiffs charge, infringes claims 1, 2, 3, '4, and 10 of patent No. I, 340,423 granted May 18, 1920, claims 1, II, 12, 15, and 18 of patent No. 1,462,456 granted July 17, 1923, and claims 5 and 8 of patent No. 1,403,983 granted January 17, 1922. The patents were applied for in the order in which they are here referred to. The defenses of invalidity and noninfringement with respect to the first two of these patents are both predicated largely upon the prior art constructions disclosed in patent No. 1,-192,479 granted July 25, 1916, to S. L. Van Meter, Jr., upon an application filed Mareh 27, 1911, and in French patent No. 474,0.19 to Baeque published February 4, 1915, and upon the unpatented prior art packs of Broadwick and of Stevens. Infringement of claim 8 of the third patent is denied, and claims 5 and 8 of that patent are both asserted to be invalid for want of invention, particularly in view of the old tailoring art.

In the early days of ballooning, the chute, connected by its shrouds or other suspending members to straps, coat, or harness worn by the balloonist and attached at its peak to- the basket by a light cord readily broken by the weight of the descending aeronaut when the lines of the parachute were made taut, was frequently permitted to drape uninclosed from the basket. Later the chute was packed in a hag attached at its upper or permanently closed end to the basket and having its lower end closed by cords of sufficient strength to prevent the chute’s falling out of the hag, yet light enough to he readily broken by the weight of the jumper when the shrouds or other suspending members projecting from the hag and attached to the jumper’s harness were made taut by his descent. Sometimes the peak of the chute was likewise attached by a light break cord to the inside of the hag. Still later the parachute was carried on the person of the aeronaut or aviator in an inclosing cover as a pack. [388]*388Sometimes the cover, held about the chute by light bréale cords, was removed by the cooperation of the weight of the jumper and a strong cord attaching the cover to the aircraft. Again, as disclosed by the prior art patents, there was no attachment whatever of chute or cover to the aircraft. In such cases the chute was manually released from its cover during the descent of the jumper by means of a pull cord running from the pack to the front of the harness. Chutes attached in any manner to the aircraft were and are known as the “attached,” “automatic,” or, since it was commonly used by balloonists, the “balloon” type. The unattached type was and is known as the “free jump” type. Both types were well known to the art before Smith filed on July 27, 1918, his application for the first of his patents in suit.

Referring to the attached type> Smith in his first patent said: “This type of parachute has a decided disadvantage in that it depends upon the aviator being able to jump and drop away from the airplane in order to extend the parachute and cause it to open. If the airplane is falling and the aviator cannot get away from it he may then merely fall with the plane.” A stated object of his invention was “to provide a parachute apparatus which is simple in construction, light in weight and effective and dependable in action.” A feature of his invention which he said in his specification would overcome the disadvantage of the attached type was “the use of a small automatically operating parachute - [attached to the peak of the main chute] to be used as'a means for relatively anchoring or holding the upper end of the main parachute to extend the main -parachute and thus cause it to properly open. I provide a small auxiliary parachute having ribs which are resiliency operated in some manner so as to automatically open when the parachute is released from the pack. This small parachute will catch the air and will extend the main parachute, if the, aviator is either falling through the air alone or falling- with his machine. If he is falling with his machine the main parachute will lift him off the machine when it opens.” He adds: “However in order to make sure of the large parachute catching the air I may provide its lower edge with ribs (any number may be used spaced around the lower edge). * * * ” The described preferred form of -apparatus includes the auxiliary chute with an option to use, or not,' ribs on the lower edge of the main chute. In fact, there is in the specification nothing to indicate that Smith’s device, intended, at least primarily, as a “free jump” device, could be used with safety without the auxiliary chute, yet the claims in issue asserted to be typical of those in suit neither expressly limit the invention to a “free jump” type of pack nor include as an element the auxiliary chute. These claims are:

“1. In combination, a parachute folded into a compact mass and having suspending members, a sheet of flexible material folded about said parachute and permitting, the ends of said suspending members to project, releasable fastening means between each edge of the sheet and some other portion of the sheet, a releasing device, and means connecting said fastening means to said releasing device.”

“10. In combination, a parachute folded into a compact mass and having suspending members, a sheet of flexible material folded about said parachute and permitting the ends of said flexible member (misprint for 'suspending members’) to project, releasable fastening means between each edge of the sheet and some other portion of the sheet, and means for simultaneously releasing said fastening means and drawing back portions of the sheet to expose the parachute.”

Manifestly these claims are directed more particularly to the pack cover and to the means by which it may be retained about and removed from the inclosed parachute, of whatever design, rather than to the specific form of parachute inclosed, or to the question of whether the opening of the pack is to be brought about by a manual pull upon a cord as the jumper is falling through the air or by the combined action of the weight of the falling jumper and a cord attached to the aircraft. With respect to the pack or cover the specification states: “The back of the harness carries -a pack 20 of some fabric material, the sides of which are folded over and meet along the center of the back of the pack at 21 and the ends of which may be folded over in any suitable manner under or over the folded sides as indicated at 22. The folded sides are held together by any suitable releasable means. ' For instance these folded sides, and ends, may be held together by a thread tie or loop as, indicated at 23; and then to the edges of these folded sides cords 24 may be attached, the cords being of sufficient strength to cause [the] loops to be broken when the wearer puds on these cords. These cords may be extended around to the front of the harness where they may be run together or attached to a single strap or any other member as indicated at 25 which may be extended across the wearer’s breast, with a central ring 25a or other handle easy for [389]*389the wearer to grasp. A pull upon the handle 25a will cause the thread ties of the pack to break and will allow the pack to open.”
