3 Claims. 1

This invention relates to an airplane toy and more particularly to a structure for causing the propulsion of the airplane about a circular path so that it can be aimed at by a toy anti-aircraft gun.

It is an object of the present invention to provide a structure for causing an airplane to take a circular path automatically when a spring device has been released to set the structure in motion and wherein the airplane not only may be driven through a circular path but also may be caused to dip while in its movement to resemble a dive bomber.

It is another object of the present invention to provide a simple arrangement for causing an airplane to move in a circular path and to dip while moving in this path, which can be easily constructed and which is efiicient in operation.

For other objects and for a better understanding of the invention reference may be had to the following detailed description taken in connection with the accompanying drawing, in which:

Figure 1 is an elevational view partly in section showing the operating structure to which an airplane is connected and by which the airplane is given a circular and dipping movement when the structure is released and showing an antiaircraft gun on a common base with the operating structure whereby shots may be taken at the airplane as it passes over the gun.

Figure 2 is a top plan view of the operating structure and of the airplane.

Referring now to the figures, Ill represents an operating structure, H is the airplane adapted to be operated by the operating structure and caused to be given a circular and dipping movement, and I2 is an anti-aircraft gun by which shots can be made at the airplane H as it passes by. The operating structure ll] comprises a sleeve l3 having a laterally extending bracket arm I4 near its upper end. This sleeve l3 has a coil spring [5 anchored to its lower end. Extending upwardly through the sleeve is a stationary member l6 fixed to a bottom face I! on which the operating structure I is supported and also upon which is supported the toy gun l2. The spring I is held within a housing l8 and its outer end is anchored by an angle member l9 secured to the bottom of the housing by a screw 2|. If the spring is to be wound the sleeve I3 is rotated or turned upon the vertically extending fixed support It. Thereafter the sleeve can be released and the airplane will be moved in a circular and downward dipping path automatically as the spring I5 is unwound from its wound up position.

On the outer end of the bracket arm Hi there is pivoted as indicated at 22 a balance arm 23 to the outer end of which, as indicated at 24, the airplane II is connected. The bracket arm [4 is supported by a brace 25 extending between the arm and the side of the sleeve I3. The upper end of the pivot arm 23 is connected, as indicated at 21, to a flexible cord 28 which is secured at its outer end, as indicated at 29, to a laterally extending portion 3| on the upper end of the vertically extending fixed member l6 lyin within the sleeve l3.

The cor-d 28 is of less length than the laterally extending portion 3|. As the sleeve I3 is released the arm I4 is carried around and with it the pivot arm 23 containing the airplane II will be swung about the fixed support 16 and about the laterally extending portion 3i thereof. When the arm l4 becomes at a station below the laterally extending portion 3|, the tension upon the cord 28 lessens and the pivot arm 23 to which the airplane or bomber II is attached will dip and the airplane will swing at its lowest point. When the pivot arm 23 is diagonally opposite to the laterally extending portion 3| the cord 28 is drawn tight causing the upper end of the pivot arm to be pulled down and thus causing the bomber to be rotated at its highest point of travel. It will thus be apparent that not only does the bomber travel in a circular path but there is a dipping motion to resemble that of a dive bomber. The bomber will dip down and then will come upwardly to its high point. All the while the child can be taking shots with the toy anti-aircraft gun to see if he may hit the airplane II. The toy gun l2 can be located at any position upon the base l'l.

Having thus described the invention, what is claimed is:

l. A toy airplane operating device for giving to the airplane a circular motion or travel in a circular path comprising a vertically extending sleeve having a laterally extending arm thereon, a pivot arm attached to the outer end of the laterally extending arm for movement therewith, an airplane connected to the outer end of the pivot arm, a central member extending upwardly through the sleeve, a base for retaining the central member in its vertically extended position, and means for connecting the upper end of the central vertically extending member to the inner end of the pivot arm, and means for causing the rotation of the sleeve about the fixed vertical central member, whereby the airplane will be extended through a circular path.

2. A toy airplane-operating device for giving to the airplane a circular motion or travel in a circular path comprising a vertically-extending sleeve having a laterally-extending arm thereon, a pivot arm attached to the outer end of the laterally-extending arm for movement therewith, an airplane connected to the outer end of the pivot arm, a central member provided with a laterally-extendedportion on its upper end extending upwardly through the sleeve, .said pivot arm extending to a point over the laterally-extending portion of said central member, means embodying a flexible cord for connecting the inner end of the pivot arm and the outer end of the laterallyextended portion of said central member, and means for causing the rotation of the sleeve about the central member, whereby the airplane will be extended through a circular path, said cord being of a less length than the laterallyextending portion of the central member, wherebyas the airp ane is, rotated not only will! itlhe givena circular path, but a. dippingzzmomement o;f --t:h e airplane 'liesembling that ofz-a diveiwil lbeeifieoted; thalaterallyextending-arm oi? the sleeve- Whe pa sin under the.laterallyeextendine-portion of the central; member penmitting the cord" to, b loosened-and-thereby allow the :outerend of the, pivot arm to, diprdownwardly as. it passes under th 1aterally-ex endme porti n- A toy airplane-operating- .dev-iceior givin to he. r ane a circularamotion or-itravel' in a circular path comprising a ventica-llyeextend-ingsleeve-,;hav.'mg a laterally-extending armthereon,
