GLIDER Filed Jan. 29, 194.;
Patente'd Mar. 7, 1944 `UNITED STATESf PATENT OFFICE GLIDER Richard D. Russell, Toronto, Ontario, Canada Application January 29, 1943, Serial No. 473,991
(Cl. lifi- 79) 9 Claims.
The invention relates to improvements in gliders as described in the present specication and shown in the accompanying drawing that forms a part of the same.
The main objects of the invention are to provide a simple, inexpensive and instructive toy which can be made entirely of cardboard or other material readily obtainable under war conditions; which can be prepared and sold in knock-down condition, thus facilitating packing and transportation and also providing interesting and instructive occupation for the person assembling same, and in which is incorporated adjustable means for varying the angle and distance of flight to meet different conditions.
The invention consists in the novel features of construction, arrangements and combinations of parts described in the present specication and more particularly pointed out in the claims for novelty following.
In describing the invention reference will be made to the accompanying drawing, in which:
Figure l is a plan view of my improved glider, with an alternate position of the adjustable nose clip shown in dotted lines.
Figure 2 is a side elevation of the glider.
Figure 3 is a plan View of the blank from which the body of the glider is formed.
Figure 4 is a plan detail of the adjustable clip.
Figure 5 is a side elevation of the weighting member.
Like numerals of reference indicate corresponding parts in the various iigures.
Referring to the drawing the body of the glider is formed from a single piece of cardboard, or other suitable material, shaped to provide an elongated main body portion I having at one end thereof opposed laterally extending parts 2 and 3 curved along their inner edges, as at 4, and cut away square at their ends, as at 5.
The blank just described is scored longitudinally in its transverse centre, as shown at E, and is adapted to be folded along this score line and when thus folded provides an elongated troughlike member 'I from which extend upwardly the projecting parts 2 and 3 to provide the tail member.
The blank before being folded is substantially ovate in plan from the front end to the lateral projections 2 and 3 so that when folded the depth of the body of the glider will be greatest at a point substantially midway between the front end and the tail member and will decrease forwardly to its nose and rearwardly to the tail.
The blank is cut away at each side midway of the length of the body to provide opposed recesses I0, which in the folded condition of the blank register with each other and provide a cross opening adapted to permit of counter-sinking the wing II.
The wing II is of considerably greater width than the cross opening in the body and to provide proper interlocking engagement between the said wing and the body of the glider the material at each end of each of the recesses I0 is undercut, as at I2, for the reception of the opposing side edges of said wing and said wing is provided with opposed lateral projections I3 adapted to fit between the opposing side walls of the glider at opposite ends of the wing opening for the purpose of preventing longitudinal displacement of the wing and for the further purpose of spreading the side walls of the glider apart to give the desired shape to the body.
If desired the wing II may be given a slightly arcuate shape in cross section by making the total distance between the extreme ends of the longitudinallyr opposed undercuts I2 less than the width of the wing so that the said wing will be held curved.
The blank of which the body is formed is cut away at each side in advance of the tail member, as at I4, and the recesses thus formed register with cross slots I5 which extend into the material at each side of the respective recesses. These slots register when the body is formed by folding the blank and are adapted to receive the tail wing I6, which latter is slotted from its rear edge inwardly to receive the tail member and hold the sections thereof tightly together, and at its forward edge is provided with substantially parallel slots Il and I8 adapted to receive the opposing side walls of the body, with the portion I9 between said slots I1 and I8 lying between said walls and preferably turned down slightly to prevent longitudinal movement of the wing I6.
The body blank is cut away centrally at its forward end and is provided with spaced rearwardly extending parallel slots 20 whereby to provide a tongue 2| `terminating short of the nose of the glider so that when the blank is folded to formV the glider the lower portions of the side walls will be somewhat shorter than the upper portions of said walls and the slots 20 will extend rearwardly in aligned relation to one another.
22 is a Weighting member consisting of a sheet of heavy cardboard, or other suitable material, adapted to be inserted between the side walls of the body and extending from the nose to substantially the front edge of the wing Il and being movable forwardly and rearwardly to the position necessary to give the proper balance to the glider, the weighting member being shaped to fit the contour of the side walls and being inclined at its inner end, as at 23, to extend upwardly over the front projection l?. of the said wing to hold said projection, or flap, down. The member 22 is also provided with a slot 25 extending inwardly from its front end and adapted to register with the -aligned slots in the body of the glider.
25 is a clip preferably consisting of a flat piece of relatively thick and heavy cardboard having a central elongated slot 25 extending inwardly from one end thereof whereby `it can be `slipped inwardly over the nose of the glider, in register with the slots 20 in the b'o'dy andthe slot '24 in tre weighting member and thus hold the side walls and said weighting member firmly locked together in any of 'their relatively adjusted positions. n
The nose clip 25 is 'preferably reduced in width towards each of its ends for streamlining -purposes.
The slot 26 in the clip 2:5 is of such length as to permit of adjustment ofthe clip longitudinally of the gliderwhe'reby to transfer the weight forwardly or rearwardly as may be required to give proper balance under different conditions. When the glider is being assembled the clip, and the weighting member 22, can be adjusted to the proper positions that when the glider is held by the wing tips it 'will be in true'balance, preferably with the nose pointing downwardly slightly. Under certain conditions, however, itmay be desirable to alter the point of lift rearwardly or forwardly. For instance, when the glider is being flown in 'a restricted area, such as in a room, and itis desired to Vrestrict the distance o'f fiight'the clip canbe moved backwardly to transfer the weight to apoint nearer the main wing and thus put the glider out of balance Ato the extent that it`will stall 'and `drop 'to the ground within a shorter distance than it would were the weightfuther forward.
While I have -illustrated and described the present preferred "form vof construction for carrying out my invention, this is capable of variation and 'modification without departing "from the spirit of lthe invention. I, therefore, do not wish to be limited to fthe 'precise detailsof 'construction set forth, 'but desire to avail myself of such lvariations Tand modifications as 'come within the fsco'pe of the appended claims.
