Sept. 13, 193 c. A. MCPHERSON TOY Filed May 24, 1932 INVENTOR ATTORNEY Patented Sept. 13, 1932 CHARLES A. MCPHERSON, OF EDGAR, MONTANA TOY Application filed Kay 24, 1932. Serial No. 618,279.

The object the provision the fly wheel of this, my present invention, is of'a gyroscopic toy which, when is turned rapidly with a str ng will balance itself on a cord track which is stretched between two points, and whereby the toy will travel toward one of such points, and when such point is elevated, the toy will travel in an oppos te direction toward the other point, so that by raising and lowering the ends of the track the toy will continue in a backward and forward movement for a long period of time, the toy being also provided with means to prevent the same from falling off of the track when the fly wheel thereof ceases to rotate.

To the attainment of the foregoing the invention consists in the improvement as hereinafter described and definitely claimed.

In the drawing:

Figure 1 is a side elevation of a gyroscopic toy in accordance with this invention.

Figure 2 is a top plan view thereof.

Figure 3 is a transverse sectional view approximately on the line 3'-3 of Figure 2.

Figure 4 is an elevation of the guard.

My improved toy contemplates the employment of a carriage. The carriage in the showing of the drawing is made up of two metal strips which at points adjacent to its center and adjacent to its ends are riveted or otherwise connected together. The body 1 of the carriage, at the center thereof, has the strips comprising the same bent outwardly and extended longitudinally in a plane with the body 1, thus providing the frame with a substantially rectangular open portion 2. The plates constituting the frame, adjacent the ends are also bent outwardly and are continued longitudinally in parallelism so that each end of the body is forked, as the parallel arms at the forked ends of the body there are the short shafts or trunnions for peripherally grooved wheels 4.

The longitudinal and parallel portions at the central part 2 of the body 1 are provided with alining openings to receive therein trunnions 5 on the ends of a shaft 6 which is fixed on and depending from the vertical ring member 7 for the gyroscope. The lower end of the ring has V-shaped depression conical end of the through the its inner face provided with a to receive therein the shaft 8 that extends hub of the fly wheel 9.

The second end of the shaft 8 is also cone-shaped and received in the conical depression 1n bolt member 10 which is of the ring 7. The 7 has centrally connected thereto or may end of a short screwed through the top ring the outer be formed with a horizontalor rightangularly arranged ring 11.

The frame, adjacent one of its ends, has

fixed thereon the upper and reduced portion 12. The guard may of a metal guard wire or may be in strip and the nature be of of a thin metal from its connected portion the guard is provided with downwardly extending outwardly inclined arms 13, and the lower ends of these arms are rounded inwardly, as at 14, and the outer faces of the said rounded portions 14 are in but the extremities thereof flared away from each other shaped mouth 15 between the contact with'each other,

are tapered or to afford a V rounded or jaw ends 14 of the guard. The purpose of this wig presently be apparent.

pull cord 16 is guided around the upper portion of the shaft 8 and has one of its ends xed to the said shaft, and cord 16 will cause a pull upon the the rotation of the shaft 8 and the fly wheel which is fixedthereto.

.T he peripherally grooved wheels 4 of the carriage are designed to travel upon a track 17. The tracl; is in element, such as a cord and length so that the ends there the nature of a flexible is, of suflicient of ma be held between the fingers of the outstretc ed arms of a person or the track may be of such length that the ends thereof are gripped between the fingers andthumbs of two persons.

track may be initially sustained in a horizontal position and started from one end toy reaches the second end the traveling toy may be of the track. 7 When the of the track the op- 95 erator slightly elevates such end, causing the toy to travel along the track t ing point oint will travel on the track in an tion, and thus by raising an and when the toy the track is elevated so that the toy oward its startreaches such opposite direcd lowering the ends of the track when the traveling toy is in close proximity to the ends of the track the toy will travel on the track for a comparatively great length of time. When the fly wheel and shaft cease to rotate the toy cannot fall off of the track because of the guard 12. The guard 12 permits of the device being inserted on the track by forcing the said track between the jaws 14 of the guard and the said guard permits of the toy assuming differentlateral angles on the track without stopping the travel of the toy on such track by virtue of either of the side arms 13 contacting with the track.

y improvement is of an extremely simple nature but will afford amusement to both young and old, and while it is thought that the foregoing description, when read in connection with t e accompanying drawing will fully set forth my improved toy, it is to be understood that I do not wish to be restricted to details of construction and, therefore, hold myself entitled to make such changes therefrom as fairly fall within the scope of what I claim.

aving described the invention, I claim:

gyroscopic toy designed for travel on a track Whose ends are held and are susceptible to alternate vertical movement to tilt and incline the track, said toy including a wheeled includes a ring frame journaled on the center freely journaled between the bottom and top of the ring frame, and a fly wheel centrally fixed on said shaft and a guard comprising a member which is fixed adjacent one end of the frame and having depending outwardly inclined arms which merge into inwardly rounded portions that afford jaws and which jaws are in spring contact with each other and said guard receiving the track therethrough.

In testimon whereof-I affix my signature 0 ARLES A. MCPHERSON.
