Aug. 27, 1935. L. G. FISCHER TOY AUTOGYRO -File d May 11, 1954 INVENTOR v 400/6 6. Each E ATTORN EY Patented Aug. 27, 1935 UNITED STATES PATENT OFFICE Claims. mus-41) This invention relates to a toy, and more particularly to a toy autogyro or helicopter.

One object of the invention is to provide a toy.

having a body formed to simulate an autoay 'o 5 and having a horizontal air-screw propeller which is adapted to be rotated rapidly by manually operated means so as to cause the toy to rise ver-' "tically in the air a considerable height.

, Another object is to provide a device of this character which is composed of few and simple parts so that the device may be inexpensively manufactured in large quantities on a high productlon basis;

A further object is to provide a toy of this type of knock-down construction which will permit of its being easily put together or taken apart by a child of ordinary intelligence, and which will permit of its being shipped and stored in flat condition.

Other objects and advantages of the invention will appear from the following description thereof, it being understood that various modifications in the details of construction and arrangement of parts hereinafter described may be'made without departing from the spirit or scopeoi the invention as defined in the claims.

The accompanying drawing illustrates a preferred embodiment of the invention, in which:-

Figure 1 is a side view, partly broken of my toy autogyro held in the handle member, in position to be operated, and showing, in dash-and-dot lines, the body member raised from the handle member;

Fig. 2 is a vertical cross-section taken on the line 2-2 of Figure 1;,

'Fig. 3 is a horizontal cross-section taken on the line 4-4 of Plane 1;

Fig. 5 is' avertical cross-section taken on the line 5-5 ofl igure 1; and

Fig. 6 is a fragmentary plan view of the horizontah propellers.

Referring tothe drawing, the device comprises a body member indicated generally by the refer-' ence character i, which body member may be made of any suitable material, preferably stamped sheet metal, shaped to simulate the appearance ofthe fuselage and appurtenant parts of an autogyro. The body as shown consists of two parallel side members 2-2 spaced slightly apart by spacers 3, to form a longitudinal slot 4 between said members, and fastened together by i or other'fasteners An imitation tractorair spindle l 5.

screw 6 is suitably mounted. atthe front end of the bodytospin idly. Near the front end,,and projecting outwardly.

from opposite sidesof the body, are apair of wingsI-l which'may be conveniently made of 5 sheet .metal stamplngs. Each wing is formed wLth an upwardly bent portion 8 at its inner endl The upwardly bent portions of the two wings are inserted in the slot 4, from the bottom, and are detachably fastened in place by means of a-metal l0 clip 9 or other fastener which passes through registered openings in the body and the wings and If desired, the wings may have tongues iii stamped therein of such shape that when bent downwardly 1g has its ends bent'upwardly as best seen in Fig. 4.

tion l2 at its inner end. These horizontal rudder members are detachably secured to the body, as best seen in Fig. 1, by a metal clip or fastener II, in a manner similar to the fastening of the wings I. This provides a knock-down construction so that the parts may be easily put together or taken 35 apart.

- Extending vertically through, and clamped to the body I, ate. point intermediate its ends, is a sleeve Hfwhich houses a vertical rotary spindle IS. The spindle end i6 and has a plate I! amxed to its'lower end.

Horizontal lifting screw-propeller members it and I9 are fastened by nuts." to the upper threaded end of the spindle ll. Each propeller is screw-threaded at its upper member has two blades and may be conveniently the desired shape. The two propeller members cram each other in the center and are pivoted Fig. 4 is a vertical cross-section taken on the.

together, of! center, by a headed pin 2], as seen made of a single piece of sheet metal stamped to in Fig. 6. This pivotpin permits one member to 40 be turned towards the other so that they may be folded compactly for shipping but holds them at an angle of ninety degrees to each other when they are fastened in operative position on the rivets moperation, the body I rises from the handle, it

will not be raised completely offthe pins until- I to rise from the handle and project itself upthe horizontal propellers have been rotated to full speed. The handle has twoforks- 21 which may be formed integral or of separate parts. Each fork has a longitudinal slot 20, best seen in Fig. 5, for receiving and supporting the body member l. I

' In the operation of the device, a cord or string 29 is wound on the spool 24.

When the cord is rapidly'withdrawn from the spool a rotary motion will be given to the latter which motion, transmitted through the pins 25 to the driving plate 11 and spindle I, will cause the horizontal propeller assembly lt-l! to spin on its vertical axis. y

Spinning of the propellers will cause the body wardly in the air as indicated by the dash-anddot lines in Fig. 1. 3

What I claim is: 1. A toy autogyro comprising a body member,

a vertical rotary spindle carried-by the body member, a horizontal screw-propeller secured to the upper end of the spindle, a driving plate on the lower end of the spindle, a forked handle memberhaving slots in the forks for receiving and supporting the body member at rest, a rotary spool mounted on the handle member intermediate the forks, and pins projecting upwardly from the spool through holes in the driving plate whereby rotation of said spool will impart rotary motion to the horizontal propellers and cause the body member to rise clear of the handle member,

2. A toy autogyro of knock-down construction comprising a body member having two parallel 'side piecesfastened together in spaced relation to provide a longitudinal slot therebetween, a

pair of planes, one projecting outwardly from each side of the body, each plane havingits innet end bent upward, the upwardly bent portions of the two planes being inserted in juxtaposition in the slot and being detachably secured 'to the body member by a removable fastener, a

vertical rotary spindle carried-by the body member, and a horizontal screw-propeller detachably secured to the upper end of the spindle.

3: A toy autogyro oi knock-down construction comprising a body member having two parallel side pieces fastened together in spaced relation to provide a longitudinal slot therebetween, a

' pair of imitation wings, one projecting outwardly from each side of the body adjacent the front end thereof, each wing having its inner end bent upward and detachably secured in the slot, a pair of imitation horizontal rudders, one projecting outwardly from each side of the rear end of the body, each of said imitation rudder members having its inner end bent upward and detachably secured in the slot, 9. vertical rotary spindle carried by the body member, and a horizontal screwpropeller detachably secured to theupper end of the spindle.

4. A toy autogyro comprising abody member,

planes projecting from the sides thereof and depeller comprising two members crossing each other at the center and extending at right angles to each, other when mounted on the spindle, and means pivotally connecting said members together at a point oif center to permit of compactly folding said members when demounted from the spindie. n v v LOUIS G. ,FISCHER.
