' TOY AEROPLANE Filed Feb. 26, 1930 3 Sheets-Sheet 3 ATTORNIY Patented July 14, 1931 11mm '1 worms, or eimnsiiu, IDAHO TOY AEROZPLANE This invention relates to certain new and useful improvements in toys of the rotary as-' cending and descendingaer'oplane type.

One'ofthe principal objects of the invention contemplates the provision and arrangement of a su portingapparatus designedto be secured in el eseproximity to the ceiling of a room to facilitate lon'g'er flights at higher altitudes. t I. 7 Another object of the invention consistsof an aeroplane ascending apparatus designed to be automatically released whereby the aeroplanes. may descend by their own voli More specifically stated the supporting apparatiis and aeroplane connections therefor are so constructed that the weight of the planes themselves will be suflicientto impart the rotary motion desired during the different modes of .flight.

With the above and other objects in view, the invention further consists of the follow ing novel .featuresand details of construction, to be hereinafter more fully described, illustrated in the aocompan ing drawings and pointedout in the appen ed claims.

indicates a cross arm of bowed format-ion having the extremities-thereof upwardly projected toward the ceiling of a room. A shaft 11 having a hook extremity 12 upon, its u permo'st end lockingly engaged within t e eye 13 of a screw eye or support 14, is jours naled at its lowermost end within the central portion of the bowed cross arm 10'; A channel member 15 inverted to dis we the bottom thereof flush against the un' er side of the cross arm 10 and to accommodate the adjacent nut equipped extremity of the shaft 11 carries a pulley wheel 16upon a ivot pin'l7 disposed between the side wa s thereof to one side of the vertical center thereof; It will thusbe noted from the foregoing description and accompanying drawings that the cross arm and channel member may rotate asa unit independently of and upon theshaft 11:v A

7 pin 18, carried by the bottom of the channel member 15'and embedded for an appreciable portion of its length within the immediate surface of the cross arm 10, is.v designed to prevent distortion 6f the channel member 15 whereby the pulle' wheel 16' will be constant- 1y aligned with t at of a companion pulley wheel 19 carried at an appropriate point in the length of the cross arm 10. A double pulley 20 telescopically associated with the shaft 11 and fixed thereon by a cross pin 21 is designed to receive the. wrappings' of a cord 22 upon the lower pulley section thereof as same is trained over the pulleys 17 and 19'. I p

Pulley wheels 23, constructed after the manner of the aforementioned pulley wheels and disposed within bifurcations in the extremitie's of the cross arm, train or otherwise direct cords or ropes 24 thereover having con nection at their uppermost ends with the upper pulley section of the multiple pulley 20, said cords beingwrapped in oppositely disposedrelation Miniature" aeroplanes or rep-j resentations thereof, such as indicated at 25 are carried upon the de ending ends of the cords 24 beyond thepul'leys 23 in the manner suggested in Figure I of thedrawing's;

v From the description thus far, it is understood that theKaer pIanes' 25 in andof their awe Wei-gm win descefid from the Figure 1 position as the cords 24 are unwound from the upper section of the multiple pulley 20 and swing or otherwise rotate the cross arm 10 in a clockwise direction. During the descending rotary motions of the planes 25, the cord 22 trained over the pulley wheels 16 and 19 respectively will be wound up upon the lower pulley section. The weight 26 carried adj acent the lowermost extremity of the cord 22 is not sufficient in avoirdupois to equal the combined weight of the two planes but will materially restrict progress of flight to such an extent that the rapidity of ascent or descent will be retarded to insure longer flights in both directions.

As mentioned previously, it is also my intention toprovide a form of plane ascending apparatus which will not only effect such function but which will also become automatically disengaged upon the occasion of the planes having reached the predetermined destination whereby one more flight, that is a descending one, will be effected unaided by the operator of the game. This automatic plane ascending and hook off mechanism primarily resides in the attaching of a ring of the construction shown as at 27 in Figures 1 and 3 of the drawings. The hook 01f element per se, indicated as at 28, preferably in the formation of a variety of monkey having its tail 29 curved after the manner of a hoop and its two arms extended above its head with both hands clasped together to provide a form of hook 30 for accommodation within the ring 27. The hands of the monkey are inserted within the ring and hooked thereon when the planes have landed and the cord 22 is wound upon the lower section of the multiple pulley 20. When the monkey is released of the hand of the operator and allowed to descend while the planes are ascending, it is to be noted that the tail 29 upon being brought into engagement with a floor surface or the landing field will rock the monkey and cause same to occupy the Figure 1 position'whereby the hands will be released from the ring 27 and the planes will then descend and land. The bowed form of cross arm not only facilitates disposing of the entire apparatus closer to the ceiling whereby longer flights may be made but the respective pulleys will also be aligned to such an extent that the cords may be most efiectively wound and rewound.

From the vertical sectional view shown in Figure 3 of the drawings, the especial construction of the multiple pulley 20 is ex hibited. The characteristic of beads 31 formed upon the inner sides of each of the end flanges of the respective spool sections will serve to prevent the winding ofthe cords in such manner that same will bind or restrict flight of the aeroplanes.

The modified form of my invention disclosed in Figure 4 of the drawings comprises essentially the general characteristics of the preferred form and closely follow same in every respect save for the channel member 15. Instead of employing the channel member 15, I make use of the pulley wheel 16 and dispose same within the bowed cross piece in a manner similar to that of the mounting of the pulley wheel 19. A bar, such as indicated at 32, having attaching rings 33 upon its ends and secured to the adjacent extremities of cords 34 oppositely wound upon the lower section of the multiple pulley 20, is also provided with a ring 35 at an intermediate point in the length thereof to facilitate accommodation of the clasped hands of the monkey. The bar 32 is obviously theequivalent in weight to the ball 26 and ring 27 employed in the preferred form.

It may be also desirous to provide a form of stand for the apparatus as shown in Figure 5 of the drawings where chandeliers and other lighting fixtures might interfere with the proper functioning of the aeroplanes. Said stand is preferably in the nature of a tube, indicated as at 35, having a floor flange or base 36 secured upon the lowermost end thereof. A pipe section or standard 37 slidably and adjustably mounted within the tube 35 and retained at any desired height by a stop collar 38, including a set screw for the purpose, and seated upon the upper end of the tube 35. A shaft member 39 constructed after the manner of the shaft 11, employed in the other forms of my invention and carrying a similar shape and type of hook 40 upon the uppermost end thereof is rigidly fitted or otherwise connected with the uppermost end of the standard or pipe section 37 through the employment of a bushing 41. The standard 37, bushing and shaft are held as a unitary structure through the employment of a set screw 42 threadedly engaging horizontally of and within the immediate portion of the aforementioned standard.

Independent or separate pulleys 43 are arranged and fixedly secured at intervals upon the outer exposed portion of the shaft 39 and upon opposite sides of a cross arm, generally designated asat 45. Bearing or spacing washers 46 loosely connected with the shaft 39 and bearing against the immediate oppositely disposed surfaces of the cross arm and the adjacent ends of the respective pulleys 43 and 44 are designed to permit freedom ,of movement to the latter mentioned arm.

The intermediate portion of the cross arms 45 is upwardly bowed whereby longitudinal passageways 47 in the arm proper may be lined up upon opposite sides of the lowermost pulley 44. Vertical passageways 48 also included in the cross arm have. their uppermost ends disposed adjacent the outermost ends of the horizontal passages 47 for purposes to be better understood in the foland it is therefore necessary to provide a semi-circular portion 52 adjacent the middle of the weight supporting bar to skip or otherwise free the tube 35 during the reciprocating actions of the weight supporting bar. A weight member 53, of annular formation, encircling the tube 35 carries hook members 54 of the configuration shown designed for detachable connection within the eyes of loops 55 formed adjacent the points of intersection between the horizontal portions of the weight supporting bar 51 and the extremities of the semi-circular portion 52.

The uppermost pulley 43 has the innermost ends of cords or cables 56 oppositely wound thereabout and guided in alignment therewith, incident to the formation of guide recesses 17 within the outermost upwardly and obliquely inclined extremities of the cross arm. Aeroplanes, Zeppelins, gliders and other representations of air craft are to be attached or otherwise suspended from the outermost depending ends of the cords or cables 56 after the manner employed in the previously described forms of my invention.

The invention is susceptible of various changes in its form, proportions and minor details of construction, and the right is herein reserved to make such chagnes as properly fall within the scope of the appended claims.
