Application mea December 16,v 191a. semi No. 266,945.

To all whom t may concern Be it known that I, STEPHEN A DoUG- LAss, a citizen of the United States, and` resident of Kirkwood, county of St. Louis, and State of Missouri, havevinvented certain new 'and useful Improvements in Toy Aerof planes, of which the followingis a spec1i\ cation containing 'a full, clear, and exact description, references being had to accompanying drawings, forming a part thereof.

My invention relates to improvements 1n toy aeroplanes and has for its speclal obJect the construction ofv a small aeroplane at minimum cost, which may be used for amusement purposes and may also be used for automobileradiator cap ornaments, and a further'object is the construction of a ltoy aeroplane having the wings or supporting planes formed of wood veneer.

In the drawings: p

Figure 1 is a side View of the complete` plane. i

2 is a top plan view.

Fig. 3 isa front elevation. Fig. 4 is a section taken on thel line 44 of Fig. 2.'

Referring to the drawings, 5 indicates the body portionA of the plane, and 6 the tail portion, the same being, formed integral, the former being provided on its under surtace with an inclined surface 7, againstwhich the lower plane is positioned, and the latter is provided with inclined surface 8.

rlFhe tail portion 6 is provided with a horizontal rudder o'r elevating plane 9 and withV a vertical rudder 10. The horizontal rudder is secured to the tail piece 6 by means of tacks or nails 11. Formed in the rear end of thetail piece 6 is a slot in which the vertical rudder 10 is inserted and `fastened by means of a tack or nail 12.

The body portion 5 is provided with a bore 13 representing the cock pit and with a counter bore 14 in which is located the handle 15, by means of which, if desired, the

` plane may be carried. lf desired, `this handle 15 may be removed and the plane may be placed upon a suitable stud applied to an automobile radiator cap. i

16 indicates the tail support which is formed by a piece of bent wire and driven, into-thetail piece 6.

17 and 18 indicate the mountings forthe wheels 19. llhese supports are lsecured to the body portion 5 by. means 4of tacks or rivets 20.

21 indicates the propeller, whichv is preferably stamped by a suitable die from a piece of sheet metal. 22 indicates the pro peller shaft or pin on which the propeller 1s loosely mounted to rotate when the aero vplane is moved through the air.

23 indicates the lower plane which is formed of wood veneer and is secured to the body portion 5 on the inclined surface -7 so as to give the same, the desired inclination. rllhis plane is straightthroughout its length as illustrated in Fig. 3, but is" inclined slightly upward as illustrated in Figs. 1 and 3.

In the -uppersuri'ace of the body portion 5, I provide two

nails

24 and 25, their heads 26 securing the upper plane 27 midway its4 length, the nail being driven into the body portion 5, deeper` than the nail 24, so as to give the same inclination to theplane 27 as that of the plane 23. The plane 27 is slightly. langer and Wider than'the plane l 23. Near each end of the plane 23, Ipro? vide a pair of openings or bores' 28 into which the ends 29 of the struts 30 are insert ed. The` other ends 31 of the struts 30 fit into openings 32 in the plane 27, these open4 ings being vertically opposite each other. The struts 30 have a tendency to bend the plane 27 upwardly so as to make a longitudinal curve in the same which will be clearly seen -in Figs. 1 and 3.

In the cock pit 13, I may, if desired, place 4 a manikin. On the top surface of the plane 27` and the under surface of the plane 23, I may place the insignia which is used by the various aviation corps.

fiflhe lower plane 23 is rigid or formed of astifer material than the upper plane 27 so vthat when the struts 30 are posltioned be- The strutsar'e of. equal length and'may be l either tapered, or provided with shoulders,

as shown; 'so-as t0 fit within the openings i ,formed in' each vend of .theplanes. These plane, however, resting on' thebody por-- Container for shipping pur #struts maybe readily inserted place by bending the .upper plane and may also bey removed byv the same operation for conven' ience in packing and assembling, the upper tion 5 when thestruts are removed, s o that a Inumber of planes can be packed in one By varying the depths t may be regulated, butalso its curvature, if

c desired. A .v

Having fully described .my invention, what I claim is: v l

1. A toy aeroplane' comprising a body and tail portion ,formed Aout of a single piece of material, a horizontal rudder secured to the tail portion, a vertical'rudder recessed into' the tail portion, a lower plane formed lof relatively sti' material secured4 in anin' clined position to the lower surface of the body-portion, a flexibleupper plane carried by the body portion, means carried by the e t the

nails

24 and 25 are 'driven into the body portion 5,

Vnot only the inclination of the 'upper plane material, a horizontal rudder secured to the tail portion, a vertical rudder recessed into the tail portion, a lower plane formed of relatively stiff material' secured in an in- 4 clinedpositionto thelower surface of the body portion, a flexible upper plane carried [by the body "portion, ins provided with heads secured to the y portion and passing through the plane, and struts located on each side of .the body portion and between the planes for bending or curving the upper plane tothe desired curvature.

3, A toy aeroplane comprising a body' and tail portion formed, out of a single piece of material, a horizontal rudder secured to the tail portion, a vertical ruddersecured to the tail portion, a lower` plane formed of relatively stiff Wood veneer secured in an inclined position'tol the lower 'surface of the body portion, a flexible upper plane formed of wood veneer mounted above the body portion, pins provided with heads secured tothe body portion and passing througli' the plane, and removable struts located on eachside of the body portion and ,between the planes cooperating .with the pins for bending and curving the upper plane to the desired curvature and inclination.

- In testimony whereof I 'have signed my name :to this specification. in presence of two subscribing witnesses.
