Specification of Letters Patent.

Patented Oct. 17, 1916.

Application filed January 8, 1915. Serial No. 1,217. 7

To all whom it may concern:

Be it known that I, FREDERICK A. Pronn'r'r, a citizen of the United States, residing at Baltimore, State of Maryland, have'invented certain new and useful Improvements in Toys; and I do hereby declare the following to be a full, clear, and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

This invention relates to toys and more particularly to an aerial toy of that type which includes a propeller wheel detachably connected with one end of a rotatable shaft mounted in a starting or launching device.

This invention has for its object to'provide an improved and simplified starting or launching device for a toy of this character embodying a screw or shaft element composed of two pieces of wire twisted to provide screw-threads and having the ends of the wires extended in alinement with the screw elements and rotatably mounted in a suitable frame.

Another object is the provision of a novel type of propeller wheel and means for detachably securing the wheel to the upper end of the screw element or shaft.

With these and other objects in view, the invention consists in the novel construction, arrangement and formation of parts as will be hereinafter specifically described, claimed and illustrated in the accompanying drawing, in which:

Figure 1 represents a side elevation of the toy, partly in section. Fig. 2 represents a top plan View of the propeller wheel removed. Fig. 3 represents a top plan view of the slightly modified form of propeller wheel. Fig. 4 represents an enlarged detail sectional view on the line 4-4 of Fig. 1, and Fig. 5 represents a transverse sectional view through one of the blades or wings of the propeller wheel illustrated in Fig. 8.

Referring to the drawing in detail, wherein similar reference numerals designate corresponding parts throughout the several views, the numeral 5 indicates the body of the frame of the launching or starting device which may be formed of wood, metal or any other suitable material and is provided at one end with an extension 6 providing a handle. A pair of angular bearing members 7 are secured in spaced relation to the body 5 and are formed with alined opening 15 having internal screwthreads fitting the screw 10,'whereby when the sleeve 13 is held against rotation and moved longitudinally of the screw 10 the latter is rotated.

The propeller wheel is preferably stamped from a piece of sheet material and includes a central or hub portion 16. in which: is secured an axially elongated sleeve or bushing 17 for receiving the upper extremity 8 of one of the wires comprising the screw 10. A plurality of wings or blades 18 are formed integral with the central or hub portion 16 of the wheel and are suitably feathered with relation to the axis of the wheel to cause the latter to mount into: the air when rotated at an adequate speed. The longitudinal edges 19 of the blades 18 are bent back so as to brace and reinforce the blades. A tongue 20 is struck out from the hub portion 16 and is adaptedto receive a pin 21 secured in the end 8 of the screw 10 to cause the propeller wheel to rotate in one direction with said screw, as will be understood, and also to permit the pin to freely disengage from under the tongue 20 when the screw 10 is abruptly stopped and the propeller wheel continues to rotate by the momentum imparted by the initial rotational movement of the screw.

Referring to Fig. 8 wherein is shown a slightly modified form of the propeller wheel, the numeral 30 indicates a strip of material stamped from a piece of sheet metal and having the longitudinal edges 31 turned back to reinforce and brace the wheel In this type of propeller wheel only two wings or blades are provided and the hub or central portion thereof is apertured to receive the relatively stationary sleeve or bushing 32 to receive the end 8 of the screw 10. The central or hub portion of the wheel 30 is further provided with a slit elongated on a line extending obliquely to a radial plane of the wheel and having the outer'edge of the In operation, the launching device is held in one hand of the operator by the handle 6 and the propeller wheel is positioned upon the end 8 of the screw and the pin 21 is en gaged with either the tongue 20 or the slot in the type of propeller wheel illustrated in Fig. 3. The sleeve or hand grip 13 is subse quently graspedby the otherhand of the operator and moved swiftly toward the 7 lower end of-the screw 10, thus rotating the latter together with the propeller wheel. When the hand grip or sleeve 13 engages the lower bearing member 7 the rotational movement of the screw 10 is abruptly stopped,but the propeller wheel continues to rotate, thus disengaging the pin 21 therefrom and per mitting the propeller'wheel to mount into the air.

The blades of both types of propeller wheels illustrated in Figs. 2 and 8 are cupped 1 or curved transversely so as to present an upper convex surface and a lower concave surface. When the propellerwheel is launched, the action of the several blades causes it to travel in an. upwardly inclined direction away from the operator. As soon as the speed of rotation is reduced to such an extent as to-no longer cause the wheel to a travel, said wheel descends. During its descent the resistance ofiered by the air causes the wheel to rotate, and the peculiar efiect of the cupped or curved blades changes the course of the wheel and causes it to float or travel back to the starting point or operator.

ing members secured to said frame, a pair of wlres twisted together forming a screw,

means securing the end portions of said wires together, the ends of one of said wires extending beyond the ends of the other wire and being rotatably mounted in said bearing members, a propeller wheel removably engaged with one of the extended ends of the relatively long wire, and means to rotate said screw.

2. An aerial toy comprising a frame, a

handle carried by said frame, a pair of bearing members secured tosaid frame, a pair of wires twisted together forming a screw, the ends of one of said wires extending beyond the ends of the other wire and being rotatably mounted in said bearing members, a propeller wheel removably engaged on one end of the relatively long wire, an internally .screw threaded bushing fitted upon the twisted portions of the wires, and a sleeve or hand grip secured to and inclosing said bushing.

In testimony whereof I affix my signature in presence of two witnesses.
