J. .H. WEST TOY AIRPLANE Filed July 12, 1939 8 sheets sheet 8 Patented July 29, 1941 S PATNT OFFICE This invention relates to toys and more particularly to airplane models which may be constructed from sheet material and are capable of gliding. This application forms a continuationin-part of application Serial No. 250,072, filed January 9, 1939, by the present inventor.

Due to the increased interest in aviation in the past few years, a large number of model airplanes of all types and descriptions have been designed and marketed. These models have had various drawbacks, however, due to the fact that those that were capable of actually gliding were too expensive and complicated in structure for general use and assembly by the average child.

In contrast to this, simplified models have been i available but these models have not been capable of extended gliding flights and/or have been so fragile that they were readily damaged.

In view of this situation, the present invention comprises a model glider that is simple and inexpensive in construction, is capable of extended gliding performances and is sufiiciently sturdy to withstand the hard use to which it would be subjected in the hands of a child. Likewise, it is {contemplated that this toy airplane may be assembled by the average child without the use of knives, scissors, or other dangerous implements. Moreover, the various parts of the assembly may be formed from a single sheet of material and without the necessity of extra parts or materials such as metal clips, glue or the like. Furthermore, the model airplanes constructed in accordance with this invention are provided withan adjustable means for changing the balance of each model thereby regulating its gliding ability so as to obtain the maximum flight according to the circumstances of each individual performance. In addition, the sheet material from which these models may be constructed, may be subject to other original uses such as disclosed in the aforementioned parent application and may comprise shirt boards for use in laundries, packaging cartons or other commercial items so that the models may be of secondary interest as a premium.

Briefly, the present invention comprises a model airplane, the parts of which are formed of cardboard or other suitable materials. The parts may be outlinedupon a sheet of material, the outlines of the parts being perforated or sufficiently weakened so that they may be readily removed from the sheet and properly folded by evena small child. These parts are arranged so as to interlock when in position and thereby preclude the necessity of clips or adhesive materials.-

A balancing weight may be located within the fuselage of the plane, which weight may be formed by repeatedly folding some of the sheet material in the manner of an accordion pleat. When this weight is inserted within the fuselage the natural'resiliency of the sheet material provides sufficient friction with the inner walls of the fuselage so that the weight will be retained in its adjusted position to properly balance the model.

The above and other objects will appear more clearly from the following detailed description when taken in connection with the accompanying drawings which illustrate by example various means and modifications for carrying out the principles of the present invention and in which like reference characters indicate like parts throughout. 7

Referring specifically to the drawings, as shown in Figure l, the parts of a model airplane may be printed on a sheet 9 of any suitable material. This sheet preferably comprises a light-weight but relatively stiff material which is preferably inexpensive, such as ordinary cardboard, although other materials such as wood or cellulose derivatives may be used for this purpose. This sheet may be provided in a suitable shape or form so as to originally function in a separate use, such as the shirt board shown and described in the copending parent application hereinbefore mentioned. The heavy printed lines |El define the parts of a model airplane such as a fuselage portion H and stabilizer wing |2, auxiliary gear simulating parts such as the motor and/or wheel units l3, and rudder 4. The heavy lines l may be perforated or otherwise weakened so that a child may remove these portions from the sheet without the use of knives, scissors, or other dangerous implements. If desired, the doors, windows, cockpits and the like may either be printed in light lines or may be completely removed in the original preparation of the sheet thus avoiding possible injury to the cutout in the process of removing these small areas.

To assemble the particular model shown in Figures 1 through 4 of the drawings, the parts are first removed from the sheet by tearing or cutting along the heavy solid lines Ill. The fuselage portion may then be folded along the heavy dotted lines Ill to form side walls l5 and a top wall IS. The dotted lines IE3 are preferably scored or otherwise weakened so that the parts may be readily folded in the proper places by a small child. Lugs I6 extend downwardly from the fuselage side walls |5 and are adapted to be inserted through slots I! which are cut in the wing l2. The wing I2 is arranged so that the tapered face thereof is toward the front of the fuselage l I, as best shown in Figure 3.

Flaps |8, I9 and 20 on the forward part of the fuselage are all bent downwardly and the extended top wall of the fuselage is bent along lines 2|, 22 and 23 so as to form the nose of the fuselage, all of the flaps 8, l9 and 20 being fitted inside of the fuselage walls l5. When these parts are so folded the laterally extending lugs 24 are juxtaposed so as to extend through the slots 25 cut through the lugs I6 thereby locking the fuselage II in assembled position and the wings l2 to the fuselage The motor and wheel assemblies l3 are slipped onto the wings l2 so that the slots 25 fit over the wings and the slots 27 in the front of the wings fit over the assemblies l3. Lugs 29 are then folded downwardly from the front edges of the wings l2 so as to prop the assemblies I3 in an upright position and to prevent their turning sidewise when the model lands.

The rudder I4 is then positioned by respective-- ly inserting the lugs 30 and 3| in the slots 32 and 33 cut in the rear of the top fuselage wall l5 and stabilizer H, the slot 34 in the rudder I4 adjacent the lug 3| fitting over the stabilizer II to lock the rudder l4 in position. In addition to cooperating and locking the rudder M in position, the lug 3| also acts as a tail skid. When the parts are finally assembled to form the model shown in Figures 2 and 3, the surplus portions of the sheet 9 or other strips of material may be folded several times to form a pleated member 35, best shown in Figure 4, which may be inserted within the fuselage to form a balancing weight. This balancing member 35 may be loosely fitted within the fuselage so that it may be readily moved to adjust the balance of the plane to increase its gliding ability.

As shown in Figure 5 the sheet 9 may be printed with heavy lines H] and scored or dotted lines ID to define parts which are adapted to form a modification of the hereinbefore described model. The modification as shown in Figures 5 through 9, inclusive, comprises a fuselage 40 comprising side walls 4|, a top Wall 42, a front Wall 43 and an under-wall 44. Other parts include a Wing 45, tall piece 46, and a stabilizer 41. When these parts are removed from the sheet 9, the side walls 4| of the fuselage 46 are bent downwardly along the scored lines If). The flaps 48 which extend forwardly from the side walls 4| are folded inwardly along lines 49 to overlie each other. Maps 58 extending downwardly from the side walls 4| are then folded inwardly along lines 5| so as to overlie each other and fiaps 52 extending from fiaps 48 are folded along lines 53 so as to overlie each other and also overlie flaps 50.

The front wall 43 of the fuselage 4D is then folded downwardly along line 54 to overlie fiaps 48 and the under-wall 44 is folded rearwardly along line 55 to overlie flaps 50 and 52, after which fiap 56 extending from the under-wall 44 may be folded around the rear edges of fiaps 50 and 52 and forwardly into the nose of the fuselage 46 to lock these portions together. Due to the fact that flap 56 is slightly wider than the interior of the fuselage 40, it will be firmly held in locked position. The side walls 4| of the fuselage 4B are provided with slots 51 which are adapted to receive the main wing 45. This front wing may be slightly wider than the length of the slots 5'! and may have slots 58 extending into its edges which are adapted to fit over the walls 4| of the fuselage adjacent the ends of the slots 57 whereby the wing 45 is locked in position, and the walls 4| of the fuselage 40 are definitely spaced.

The rudder 46 is then positioned within the slot 59 in the rear end of the fuselage top wall 42, the slot 60 in the rudder 4B fitting around said top wall 42. When the rudder 46 is so positioned, the slot 5| thereof coincides in position with the slots 62 in the rear portions of the fuselage side walls 4| so that the rear stabilizer wing 41 may be inserted through the slots 6| and 62, th stabilizer 41 being provided with slots 63 adapted to fit around the walls 4| of the fuselage and thereby lock the whole assembly in position. Wheel portions 64 may be integrally formed with the side Walls 4| and extend downwardly therefrom. The various flaps and tabs of the parts may be identified and the assembly may be described in printed directions upon one portion of the sheet 9. After assembly, this portion containing the directions may be folded to provide a balancing weight 35 to be inserted within the fuselage 40.

Still another modification is shown in Figures 10 through 15. This arrangement is such that two sheets are required to supply the various portions of the model as shown in Figures 10 and 11. The fuselage 10 and balancing weight 1| may be printed upon one sheet 9:2 as shown in Figure 10, and the wing 12, stabilizer I3 and rudder 14 may be printed upon a second sheet 919 as shown in Figure 11. Other portions such as wheels 83, hatches 81 and the like, and the directions for assembly may beprinted upon the sheets in suitable places, In this modification the fuselage I comprises side walls I and a top wall I6, the structure being somewhat simplified in that it does not include front and bottom walls. The side walls I5 of the fuselage I0 are provided with slots I! through which the wings '12 may extend.

The tail assembly is similar to that shown in the last described modification in that the rudder I4 is inserted in the slot 78 in the rear of the top wall I6, the slot I9 of the rudder I4 fitting around said top wall I6. The slot 80 of the rudder It is then aligned with the slots 8! located in the side walls I5 of the fuselage l6, whereupon the rear stabilizer wing "I3 may be inserted through the slots 86 and BI to lock the assembly in position. A rear skid member 82 may be carried by the rudder piece It so that it is rigidly held in upright position by the tail assembly. Front wheels or skid members 83 may be folded along lines 84 to form V-shaped members and the tabs 85 carried thereby may be inserted through the slots 86 located in the wing 72 on either side of the fuselage. The tabs 85 are folded flat against the top of the wing as best shown in Figure 14 so that the supporting members 83 are rigidly secured in position.

A hatch 81 may be folded centrally thereof along line 38 and the tabs 89 carried thereby inserted through slots 90 located in the lines Ill'Iil along the top corners of the fuselage "Ill. The weight member I! is provided with notches SI so that when it is folded along lines I0 the corner is bevelled so as to not project beyond the side walls of the fuselage as best shovwo in Figure 13. This weight II is inserted within the side walls I5 of the fuselage Iii and between the top wall I6 of the fuselage I0 and the wing I2. the fuselage and is provided with sufiicient friction to retain it in any preferred position. If desired, an ordinary rubber band or elastic 93 may be wrapped around the nose of the fuselage to form a more compact assembly.

Still another modification is shown in Figures 16 through 20. The parts for forming this modified model are all arranged on one sheet 9 as shown in Figure 16. This modification is also provided with a simplified fuselage 108 which comprises merely side walls It! and a horizontal wall I02, that forms the bottom wall of the fuselage I09 which is open at the top. Slots I63 are located near the top edges of the side walls I0! and are adapted to receive a wing I94. The tail assembly is slightly different in that the rear skid member I65 carried by the rudder IE6 is adapted to be inserted through a slot I01 located near the rear end of the bottom wall IE2.

When the skid IE5 is inserted through the slot It], the slot Hi8 out in the rudder i6 is then arranged in juxtaposition with the slots I09 located in the rear portions of the side walls IEJI. The rear stabilizer wing Ill] may be inserted through these slots I93 and I09 to lock the tail assembly in position. Front skid members III are provided with tabs II2 which are adapted to extend through slots II3 located in the lower front portions of the side walls IiII of the fuselage me, A balancing weight H4 is provided to be folded and inserted between the side walls WI. The front skids III may be positioned by the tabs H2 which are held between the balancing weight H4 and th sid walls iIlI as best shown in Figure 18.

In this position it is held within at The balancing weight I I4 is provided with a plurality of slots H5 which areadapted to coincide, when the weight is folded, and fit around the wing IE4 when the weight H4 is positioned within the fuselage I00, as best shown in Figure 18. The slots H5 are open at one end and are considerably longer than the width of th wing I04 so as to permit adjustment of the weight II4 to secure the proper balance of the plane. It will be understood that these slots do not have to be opened at one end, just so they are long enough to permit adjustment of the weight and thereby regulate the balance of the model. In this manner the balancing weight is retained in position within the fuselage when the fuselage is not large enough to completely house the weight.

It has been found that by forming the herein described model planes from a light-weight but substantially rigid material, that these models are capable of prolonged gliding flights provided they are properly balanced. As it is desired to provide these models as cheaply as possible it would be impractical, and virtually impossible, to provide a prearranged weight that would be suitable for all models to obtain the maximum performance. Accordingly, by providing a weight formed of folded material comprising the same sheet as the parts of the plane, no extra parts are required. Moreover, the weight may be adjusted and frictionally maintained in adjusted position so as to secure the maximum performance from each individual model or to regulate each individual performance, according to the surrounding circumstances. Actual tests have proven that these models are capable of unusually long flights ranging from 50 to 200- feet and that the planes make a proper landing so that they are not damaged. These planes are reasonably indestructible so that they are not too readily damaged or demolished due totheir use by small children. It should be noted that these models are complete in themselves in that all the necessary parts may be provided upon a single sheet and that the parts may be arranged and interlocked so that no additional means such as clips, glue or the like is necessary to the assembly to form a capable flying model airplane,

Although certain specific embodiments of the present invention have been shown and described, many modifications thereof are possible according to the specific need of each case. The individual features of the several models hereinbefore described may be variously combined within any one model. The invention, therefore, is not to be restricted except insofar as is necessitated by the prior art and by the spirit of the appended claims.
