HELICOPTER TOY Filed April 50, 1951 Patented Feb. 2, 1932 VNLHTE STATES ALBERT VOELLMEGKE, or LITTLE nocx, ARKANSAS HELICOPTER TOY Application filed April 30,

The invention relates to toys of the type employing a spiral rod and a spinning or propeller device mounted onthe spiral rod and given a twisting motion when moved axially of the rod so that when released from the rod the spinning device will fiy into the air, and has for its object the provision of improvements in this type of toy whereby the spinning of the spinner or propeller is more efiectively accomplished by reducing to a minimum drag on the propellingdevice, and also an improved construction of operating or propelling member whereby the spinning of the propeller is more effectively accomplished as stated, and also whereby danger of injury to the operator is reduced to a minimum.

The invention will be described in detail hereinafter and will be found illustrated in the accompanying drawings, in which Figure 1 is a side view of the helicopter toy involving improvements,

Figure 2 is a fragmentary view on an enlarged scale showing some of the parts in section,

L Figure 3 is a side view in elevation of the operating or propelling member,

Figure 4 is an end view,

Figure 5 is a top plan view,

Figures 6, 7, and 8 are transverse sectional 3U views taken on planes indicated by the lines 66, 77, and 88 of Figure 3,

Figure 9 is a transverse sectional view of the propeller on a plane indicated by the line 99 of Figure 1, and V Figure 10 is a view of the blank from which the hand engaging portion of the propelling member is formed.

Similar reference characters are used to designate corresponding parts in all the views.

The invention relates to that type of toy employing a spiral rod and a spinning device or propeller mounted thereon and given a y spinning action by axial movement on the rod, and in the drawings the spiral rod is indicated at 1 and as shown is of a type that is originally Hat and twisted to form the spiral, 2 indicating a hand hold at the lower I end of said rod that is shown in the drawings as a hook, but may be of any other suitable 1931.

shape. 3 designates the spinning device that is preferably made of a piece of sheet metal and has its ends 4: tilted or canted to form a propeller. The metal of the spinning device intermediate of its ends has a pressed downwardly rib 5 that serves to reinforce the spinning device and also serves to lift it from the propelling member that will be hereinafter described to reduce friction in the act of operating the toy.- 6 designates an elone0 gated opening intermediate of the ends of the rib 5 and in the middle of the spinning device to receive the spiral rod 1 to provide for rotation of the spinning device on the rod when propelled by upward movement of the op'erating device.

The propelling member or operating device for the spinning member 3 consists of two partsdesignated 7 and 8, both parts being preferably made of sheet metal, and the part 7 is formed from a blank as shown in Figure 10. In shaping the member 7 from the blank shown in Figure 10, it is first bent intermediate of its ends into a U-shape substantially on the lines 7 The two ends of the member 7 are then bent laterally substantially on the line 7 to form inclined sides 9 as best shown in Figures 6, 7, and 8, and the side 10 intermediate of the inclined side 9, said side 10 being concaved slightly as best shown in Figures 7 and 8. 11 indicates an opening in the member 7 to receive the rod 1 when in position thereon. 12 designates tongues extending outwardly from the I end edges of the member 7 that engage in elongated slots 13 in the member 8 to secure the member 8 to the member 7 in assembling the device. The member 8 is pressed to provide an upturned flange 14: around its outer edge that not only rigidifies the member 8, but also serves to prevent the operators fingers from being engaged by the spinning device 3 when in operation. Centrally of the member 8 is a dome-shaped projection that extends slightly above the edge of the flange 14, and is provided with an opening 16 to receive the rod 1, said opening being obviously alined with the opening 11. In operating the device the dome-shaped projection 15 engages the rib 5, and this is the only art of the spinning device 3 that is engaged by the operating device consisting of the

members

7 and 8, so that friction between the operating member and the spinning device 5 is reduced to a minimum, and the effectiveness of the toy is thereby obviously enhanced.

What is claimed is In an aerial toy of the type employing a spiral rod and a spinning device for mount- 10 ing on the rod, a propelling member for the spinning device adapted to slidably engage said rod, comprising a U-shaped member of sheet metal having an opening to receive the rod, the edges of the legs of said U-shaped 15 member inbent toprovide a convenient hand held, tongues on the endsof said inbent portions, a plate provided With, openings to receive'sai'd tongues and secured to said U- shaped member, and a dome-shaped exten- 20 sion on said plate having opening therein alined With the opening in the U-shaped member and to also receive the spiral rod,'

said dome-shaped extension being adapted to engage the spinning device for propelling it.
