AIRCRAFT Filed Nov. 2, 1927 5%a/s wk ATTO R N EY Patented May 6, 193% STAT CHARLES J. MULZER, OF EVANSTON, INDIANA AIRCRAFT Application filed November 2, 1927.

This invention relates to certain novel improvements in air crafts and more particularly to a buoyanting equipment for an air craft, and has for its principal object the pro- 5 vision of an improved construction of this character which will be highly efficient in use and economical in manufacture.

Among the several objects of this invention is to equip an air craft with buoyanting elemerits whereby should the air craft find it necessary to land upon a body of water the elements will function to retain the air craft in floating position and to accomplish the many objects of this invention particular attention has been directed to the location of said elements whereby by reason of heavy seas the elements will function to not only keep the air craft floating but also neutralize the same.

Other objects will appear hereinafter.

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by 5 reference to the accompanying drawings,

showing the preferred form of construction and in which:

Fig. 1 is a plan view of an air craft embodied in the invention;

Fig.2 is a front elevational view of the same; and

Fig. 3 is a side elevational view of the same.

Referring more particularly to the drawing, an air craft is indicated at 10. This air craft includes a body 11 and the usual planes 12 and 13. The body 11 in the present instance is provided with a buoyanting element. This buoyanting element is indicated at 14; and is preferably formed of such material as will not sink when placed upon a body of water and this element may be and is preferably treated with an agent which will prevent deterioration by water.

This element is in the form of a collar and 5 is mounted to embrace the body 11 to the rear of the pit 15. It is obvious that this element 14 may be forwardly of the pit 15 should conditions permit such positioning of said element. To the plane 13 which in the present instance is the lower plane of the air craft Serial No. 230,600.

there is mounted on the under side thereof a second buoyanting element 16. This element 16 is formed of substantially the same material as the element 14 and extends completely across the under surface of the plane 13 and is secured thereto by means of bands or strips 17. The edges 18 of this element 16 are beveled as shown in the drawing whereby to eliminate square edges which would interfere with the movement of the air craft by action against the wind. The edges 19 of the ele ment 14 are likewise beveled for substantially the same purpose. By extending the element 16 completely over the under surface of the plane 13 it will be manifest that the buoyanting action of the element 16 is equally distributed and thereby will function to retain the plane substantially neutralized when in rough seas. The element 14 functions primarily to buoy the tail end of the plane and this element may be of such thickness as to sufficiently dispose this tail end above the water.

The rudders of the plane are indicated at 20 and the under surface of these rudders have likewise mounted thereagainst buoyanting elements 22 formed in substantially the same manner as the elements 14 and 16. These elements are secured to the rudders by means of bands or strips 23 and likewise have their edges 24 beveled so as not to interfere with strong winds.

From the description herein taken in connection with the accompanying drawing it will be manifest that by providing the water engaging portion of an air craft with solid buoyanting elements that an air craft is provided which will assure substantial safety to the operators thereof when traveling over a body of water and when finding it necessary to land upon the water.

WVhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departing from the spirit of the invention. 1, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come Within the scope of the appended claim.

Having thus described my invention what I claim as new and desire to protect by Letters Patent is In an air craft, a fuselage, Wings arranged adjacent the forward end of said fuselage, tail Wings at the rear end of said fuselage, sections of buoyant material adapted to be dis posed on the under side of said Wings to substantially cover the area thereof, means for securing said sections of buoyant material to the under side of the Wings, and a collar of buoyant material arranged on said fuselage adjacent and to the rear of the cock-pit in said fuselage.

In testimony whereof I aflix my signature.

CHARLES J. MULZER.
