AERIAL TOY I Filed April 14, 1930v 2 Sh eets-Sheet 2 I INVENTOR I 794., ATTORNEY Patented Feb. 3, 1931 UNITED STATES PATENT OFFICE I JOHN B. TEGARTY, OF LAKEWOOD, OHIO, ASSIGNOR OF ONE-HALF TO ARTHUR H. VAN HORN, 01' LAKEWOOD, OHIO AERIAL TOY Application filed April 14,

My invention is an improvement in aerial toys and the method of making the same.

I am aware that aerial toys have been made heretofore by stamping or cutting the various 6 parts, including the fuselage and wings, from sheet material as separate parts and then as sembling these parts in their properly related positions. Aerial toys such as gliders formed in this way are usually cut and sold by the manufacturer in knockdown form. So far as I am aware, however, aerial toys such as gliders have not been formed heretofore by simply printing or otherwise defining the outline of the toy on a single sheet of ma terial, whereby the user may construct his own toy by simply cutting around the outline to form a single blank, andthen folding portions of the blank to form the fuselage and able a toy of the above named character to be formed with hollow aerofoils' having a predetermined camber.

Another object of my invention is to construct a rigid, sturdy aerial toy from a single I cut out blank and to brace the aerofoils against lateral and longitudinal stresses or sudden impacts.- 4

A still further object of the invention is to construct a simple cut out toy as a unitary structure from a single sheet of material on which the outline of the toy may be defined 'on one side of the sheet only and on which directions for cutting and assembling the toy may be printed. In this manner I have provided a simple article which may be manufactured very inexpensively and which is capable of shipment in flat or rolled form.

Other objects and advantages of my 1nven-. tion will become more apparent as the follow- 1930. Serial No. 444,308.

ing description of two embodiments thereof progresses, reference being made to the accompanying drawings in which like reference characters are employed to designate like parts throughout the same.

In the drawings- Figure 1 is a plan view of the preferred embodiment of my invention, showing the sheet of material on which the outline of the aerial toy is defined.

Figure 2 is a side. elevation of the toy assembled after being cut from the sheet in Figure 1.

- Figure 3 is an end view of one of the aerofoils showing how the same is formed. In

full lines I have shown the first step of bending or folding-the foil and in dotted lines I haveillustrated how the foil sections are secured together to form a cambered aerofoil.

Fi ure 4 is an end elevation of an assembled aero oil.

Figure 5 is a plan view of the assembled toy showing the method of supporting and bracing the aerofoils. V

Figure 6 is a front elevation of the assembled toy.

' Figure 7 is a fragmentary elevation of the fuselage and an aerofoil illustrating a modification of my invention.

Referring first to Figures 1 to 6 inclusi ve, illustrating the'preferred form of my invention, and more particularly to Figure 1 in which I have illustrated the sheet of material on which the outline is defined, I prefer to employ a sheet 1 of flexible material having a suitable texture and thickness, and

which is stiff enough to impart ruggedness and rigidity to the toy formed therefrom.

On one face of the sheet an outline of an aerial toy such as a glider monoplane or the like, is defined by any suitable means, as by printing, impressing or partially cutting or otherwise marking the outline thereon. In the present embodiment I have illustrated the outline as printed on one side of the sheet, 2 representing generally the fuselage and 3 the aerofoils.

In the illustration the portions of the outline shown in solid lines indicate the lines of cut, while the portions shown in dotted lines indicate the lines along which the blank is bent or folded. If desired, indicia 4 may be applied to the blank to assist the user in applying adhesive as in assembling the fuselage or the aerofoils. The outline may be more completely applied to the sheet by printing a cabin on the fuselage and other distinguishing data that will bring out the details of a commercial machine. The printing may be confined to one side of the sheet and in this event the entire surface may be colored ormarked with the exception of the under surface of the elevators.

The cut out blank outlined on the sheet 1 comprises the essential parts of a toy aero plane or glider, including the fuselage 2, the aerofoils 3, the elevators 5 and the rudder 6. The toy is developed along a center folding line 7 so that the sheet may be folded along this line and both sides of theblank cut in one operation. I prefer, however, to out along the solid lines with the sheet flat since this lessens the tendency to cut blindly and, of course, eliminatesslipping of the folded sections which would otherwise result in inaccurate cutting.

Assuming now that the blank has been cut from the sheet along the general outline as shown, the next step consists in cutting along the

lines

8 and 9 to separate the inner edges of the forward aerofoil sections 10 from the forward end 11 of the fuselage, thus permitting these sections to be folded back along the broken lines 12 to overlap the rear aerofoil sections 13. It will be noted that by cutting along the

lines

8 and 9 straps or tabs 14 are formed, the purposes and advantages of which will be described more fully hereinafter.

It will also be noted that by cutting along the lines 15 a lateral brace 16 is formed between the aerofoils and the fuselage, thus materially increasing the rigidity and ruggedness of the toy at a point where strength is required.

The elevators and rudder are formed as outlined, it being only necessary to sever the blank along the lines 17 to separate these elements.

Assuming that the blank has been cut from the sheet as indicated and described, the next step in-the construction of my aerial toy consists in folding the various parts along the broken lines. The blank is first folded down along the line 7 and a drop of adhesive placed approximately at 4 and 4a on the inner walls of the complementary fuselage section to secure them together. The aerofoil sections are then bent downwardly along the lines 18 to a position approximately at right angles to the folded fuselage. The aerofoil sections 10 are then bent back along the lines 12 until the front edges overlie the rear edges ofthe sections 13, as shown in solid lines in Fig. 3.

The aerofoils are formed to simulate as nearlyras possible the aerofoils used in present day 'flying craft, that is, they are formed with a camber of the upper and lower. surfaces are secured together to form a eambered aerofoil, possessin" a higher degree of rigidity than could be 0 tained by merely forming a eambered aerofoil of a single section from the same material. After one of the aerofoils is formed the strap 14: extending therefrom is inserted between the sections l0-and 13' of the other aerofoil, which is formed in a'similar manner. The strap of the latter aerofoil extends out over the upper surface of the first aerofoil and may be secured thereto by applying adhesive and pressing the parts together.

It will be observed that the aerofoils may be set or disposed at predetermined angles to the fuselage by securing the strap 14 at predetermined 01nts along an imaginary line extending longitudinally of the aerofoil. If desired, indicia may be applied to the surface of one of the sectionslO as at 20 to register with the edge or indicia 20a. on the strap. The strap of the aerofoil first formed may be secured within the second wing-by adhesive without applying pressure, it being sufficient to secure the latter strap and allow the former obvious t at the rudder may be bent about a vertical axis, if desired, to control the horizontal line of flight.

In Fig. 2 I have illustrated means for shifting the center of gravity of the toy,

which consists of applying a metal clip or the like 25 to the fuselage. The clip may be removably attached and adjustedalong the fuselage to shift the center of gravity.

It will be seen that by my invention an aerial toy such as a glider, may be constructed as a unitary, structure from a single sheet of material. My invention provides considerable' entertainment for children as well as grown ups, is highly educational, since it embodies many of the fundamental principles of aeronautics, and enables the user to study these principles in actual practice. Furthen more, the invention is extremely simple of construction, requiring only that the outline of a complete aerial toy be defined on a single sheet of material to be cut out and assembled by merely folding certain portions of the cut out blankand applying adhesive thereto at indicated points.

In Fig. 7 I have illustrated a modification of my invention in which a portion 30 of the lower aerofoil sections may be cut and folded back and secured at their ends 31 to the fuselage to form an additional brace for the aerofoils. In this mannerthe assembled aerofoils may be braced as a unit against wobbling on the fuselage.

Instead of using a clip as a means of weighting the nose of the toy, I may insert a longitudinal member between the folded sides of the nose of the fuselage, securing the same in an adjusted position by any suitable means,

thereby reinforcing the nose against dist0r-' of the. claims.
