ROTATING TOY John H. Bacon, Wellesley, Mass. Application February 12, 1949, Serial No. 76,015

Claims. 1

The present invention relates to a toy or amusement device is which animation or motion is provided by simple means in such a way that the toy has a particular attractiveness. A remarkable feature of the toy is that it requires a very little amount of energy to keep it going for a comparatively long period of time. A simple twisted rubber band can easily keep the toy in operation for a period of more than an hour. In the form in which the toy is contemplated for use, it may represent in caricature a person fishing, or other animated actions may be operated with the same principle.

The present invention does not contemplate the use of the toy for a game. However, it may be used for this purpose if the structure and animation are applied with that purpose in view. The toy of the present invention is intended to be amusing and also to illustrate principles of mechanical motion which are interesting to observers and to a great extent educational from the point of view of mechanics and mechanism.

Such features of interest will be particularly pointed out in the description of the invention contained in the specification annexed hereto when taken with the drawings illustrating the invention in its embodiment and modifications thereof as will appear in connection with the drawings in which Figure 1 shows an elevation of the invention in one form. Figure 2 is a section taken on the line 2-2 of Figure 1. Figure 3 is a section taken substantially on the line 33 of Figure 1. Figure 4 shows in section a modified form of the winding means of Figure 1. Figure 5 shows a plan view of the detail shown in Figure 4, as viewed from the bottom. Figure 6 shows a further modification of the view shown in Figure 1 with additional means of animation. Figure 7 shows a detailed section taken through the lower tower portion of Figure 6. Figure 8 shows the same section as Figure '7 but with the elements in a diflerent position. Figure 9 shows the same section as Figure 7 with the elements in a still further position. Figure 10 is a horizontal sectional view through the base of the tower just above the horizontal bar member indicated therein. Figure 11 shows a modified detail of the detail shown in Figure 5. Figure 12 shows a plan view of the detail of Figure 11 as viewed from the top of the base. Figure 13 shows a section taken substantially on a line l3-|3 of Figure 12.

In the arrangement shown in Figures 1, 2, and 3, the toy is provided with a base I which may be a rectangularpiece of cardboard, plastic, wood, metal composition or other material inlaminated or integral sheet, and while preferably a rectangular shape is employed, other shapes or forms may be used if desired.

At the center point of operation of the board i, there is positioned a tower 2. This tower 2 is preferably hollow on the inside and stands over a disk 3 which is held to the base I by a pin or rivet 4. Ehe disk 3 fits snugly within the bottom end of the tower 2 which may be tapered as indicated in Figure l and which at the top is capped by a cap 4 which is provided with downwardly extending forming a reasonably snug fit about the upper end of the tower so that the cap will. not readily come on. Resting on top of the cap is a washer B and on top of this washer is a platform I which will be presently explained. A thin rod or shaft 3 is held firmly in the platform assembly and this rod extends down through the washer and the cap into the top of the hollow cone where it is terminated in a hook 9. An elastic rubber band it is hooked over the hook 9 at the top end and at the bottom end it is passed through the slot H in the disk 3- and looped around the neck of the rivet 4 between the disk 3 and the base I. The rubber band is sufiiciently taut to hold the rod or shaft 8 in place in a vertical direction. The washer 6 may be of such a type as to minimize the friction between the platform 7 and the cap 4 so that the platform 1 may be readily rotated both in the winding and in the unwinding of the rubber band It which acts as the motor or driving device in the present toy. The platform I has centrally mounted on it two upright members It. and l3 which may be provided with lithographed prints or other decorative covering sheets if desired. The upright sheets [2 and [3 may be set in the platform 1 or they may have outwardly extending flanges by which they are held to the platform. Any suitable method of attachment that would make the uprights fairly secure is satisfactory. In fact, the uprights may be secured by means of the wire a which passes between the two upright sheets or plates as indicated at M by the dotted line over the neck of the rivet i5 and out through the end edge as indicated by the dotted line [6 from which it extends as a pole ll outwardly inclined and downwardly as shown in a curve or with a bend as indicated at the point of fiexure 58. This pole or rod 3! is preferably not of rigid material although a rigid pole may be used. The pole or rod l! is sloped downwardly and its normal inoperative position terminates in an eyelet it which. lies within the radius of the flexible or rigid pole or stem 2% when the rod is at reststhe suspended weight 22, line 2 l, and flexible rod outward, and at normal rotating velocity provides sufiicient centrifugal force so that the eyelet 19 will be forced outward and come in contactwith the upright rod 28'. Since the little weight 22 under these conditions is still proceeding in a tangential direction with reference to the circle described by the end of the cord, it will wind up about the upright pole or rod 20 until the cord 2| is entirely wound about the pole. When this has occurred, the little weight 22 will tend to drop on the pole 20 which has little friction and begin to unwind, completely unwinding and permitting the eyelet therefore, which is now not subject to centrifugal force, to assume the position shown in Figure 1 at which instance the motor Ill takes over and again begins to rotate the pole to the position of the opposite upright 24 and the same cycle of operation just described begins over again.

In the arrangement just described, the cycle of operation as far as time is concerned remains quite uniform and if the rubber band is given about 100 twists by rotating the pole in one direction, it will take about one hours time for t way and rotating the pole about the central axis by driving it with the finger. For this purpose, a small hook 25 may be mounted on the upper end of the pole in which the line 2! may temporarily be held while the motor is wound. lhe motor lil however, may be wound through the base and such a system is shown in Figures 4, 5, 13, 14, and 15.

In Figure 4, the rubber band it is threaded through a hollow rivet 2G in the base I and is looped about the right angle crank 21, one side of which 28 lies flat against a recess 29 in the bottom of the base I. The arm 23 is positioned diametrically across the hollow rivet 26 and serves to prevent the rubber band from pulling back th'roughthe rivet and also. serves as a winding. means. The crank arm 3n may be. turned downward as indicated in Figure 4 and held in the fingers to wind the motor. When not in use, the crank arm 30 is turned downward as shown in Figure 5 and will resist unwinding by engaging the side wall of the recess 29, since the hollow rivet is not stationed in the center of the recess 29, but is placed eccentric with respect to it so as to'prevent the motor from unwinding.

In the arrangement indicated in Figures 11, 12, and 13, a slight modification of this structure is shown. In the construction shown in these figures, the base 3! corresponding to the base I is punched out with a hole 32 which is generally oval or diamond in shape. symmetrically centered in this hole is a base disk 34 over which is placed a very much larger disk 35 covering the 'entire hole 3-2 and on top of this, centered with the'disk 3'4, is'the disk 33 corresponding to the disk 3, of Figure These three flat disks or plate ar r vete .toeethe it e lo ive 3,6.

through which the rubber band I0 is passed. The rubber band loops over the right angle crank 31 which has one arm diametrically positioned across the hollow rivet and the other arm at right angles thereto. As indicated in Figure 11, the motor is wound in the direction of the arrow 38 so that the tendency for the crank to unwind will bring the handle 39 of the crank when laid down fiat in the hole against the wall of the recess 32 as indicated in Figure 1.3. The disk 35 which covers the hole 32 may be cemented to the base 3| around its edges which will hold the whole assembly in proper position. The disk 34 lies well within the lower surface of the base 3| and so also the crank arm 39 when laid over on the side.

is shown as finished off with a cup-shaped plat-= form it provided with an upright railing 41 in which stands a fisherman, figure 48, on the outside of the housing 4.! which may simulate a lighthouse, and in fact, if desired, may contain a battery and light shining through transparent or open walls in the housing 43. The pole 4| extends from the fisherman in the top. of the lighthouse and similarly as described in Figure 1 in a position at rest the eyelet an lies within-the radius of the upright poles 43 and 44; When, however, centrifugal action of motion throws the pole or weight 5| outward, the eyelet 5G will hit the pole 44 or may even lie. beyond it.

The chief distinction between the modificationof Figure 6 and that of Figure 1 lies in the additional animation provided by the bar 52 sup-- ported in a horizontal position above the base 40. This rod or bar 52 may be straight or slightly curved as shown and is made to oscillate somewhat like a seesaw as will be presently described.

The top cup platform 46 of the lighthouse is the member which is rotated. This is supported on the end of the stationary cylinder 45 over the end surface of which the base of the platform i'a turns or spins. The platform is provided with a shoulder 53 at its base from which a cylindrical boss, short neck,- or plug 54 extends from which the hook 55 is suspendedcarrying the top end of a rubber band 56. The band 55 is positioned in the axis'of the plug or neck 54 and is surrounded by a hollow cylindrical tube 5'! which is concen-' trically positioned with respect to the outer cylinder 45 and which is firmly attached to the plug 54 so that the cylinder 5'! turns with the turning of the platformv 45.- The lower end of the cylinder 51 terminates. at a. point above the:

bar 52. At the end of the cylinder 5? thereis' formed two projecting

prongs

58 and 59"posi-" The lighthouse Figures '7, 8, and 9 show successive positions of the hollow cylinder 51 in its rotation. First the prong 58 engages one of the springs 6| and the prong 59 the other, and then in the next rotation of 180 the downwardly extending prongs each engage the other springs. As indicated in Figure 9, the bar 52 will be tilted or oscillated through an are about the spring 6| as a point of suspension. On one side this oscillation will tip the bar initially in one direction of rotation while the opposite bar will be initially tipped in the other direction of rotation. As the prongs 5t and 59 leave the spring projection 62, the rods will oscillate back and forth in a seesaw fashion for a considerable period depending upon the damping of the system. The engagement of the prongs with the spring is made at the time of maximum velocity of rotation of the cylinder 6'! which is in a position substantially at right angles to the line through the axis of the cylinder and the poles 43 and 44.

The bar 52 may carry light scenery such as waves for instance so that the animation or motion provided by the oscillation of the bar will give the effect of a moving ocean while the fisherman is fishing. As in the construction indicated in Figure 1, the rubber band 56 is attached to a hook 63 which corresponds in general to the rivets or means for holding the lower end of the rubber band indicated in the other figures.

The device in accordance with the Figures 6 to 10 inclusive operates quite similarly with the additions which have already been described to that of the device of Figure 1.

Various other modifications and arrangement of parts may be obtained and while it is of considerable advantage for simplicity of operation, cheapness of manufacture to use a rubber band as a source of prime mover, it is nevertheless possible to use electrical power to provide longer or continuous operation or mechanical power in the form of watch springs or other similar devices.
