My invention relates to an automatic steering mechanism for power driven toys such as toy automobiles, tractors, tanks, aeroplanes and boats.

An object of my invention is to provide a steering mechanism for a toy which may be set by a child to cause the toy to travel a predetermined desired course.

Another object of my invention is to provide an automatic steering mechanism for a toy which includes a plurality of manually operable stations or stops adapted to be selectively adjusted to cause the top to travel a predetermined desired course during its operation.

A further object of my invention is to provide an automatic steering mechanism for a toy capable of being operated by a child in the home, whereby the child may cause the toy, by proper and selective adjustment of stops, to travel a selected predetermined course around or between chairs or other obstructions, and may cause the toy, ifrdesired, to return to its original starting position.

My invention further contemplates the provision of an automatic steering mechanism for a toy whereby a child may, prior to the operation of the toy, select any desired course which may include a path of travel around and between obstructions, and by setting suitable stops cause the toy to turn at the proper points to avoid the obstructions and to thus travel the desired contemplated course.

Still another object of my invention is to provide an automatic steering mechanism for a toy wherein suitable spaced stops are provided, the distance between adjacent stops representing a predetermined portion of the travel of the toy, the stops being capable of being selectively set and being interconnected with the steering element of the toy in a manner such that the toy may be caused to make right or left-hand turns at the desired points in the travel of the toy, whereby the toy may be caused to travel a selected predetermined path.

My invention further contemplates the provision of an automatic steering mechanism for a toy whereby two children may play with the toy at opposite ends of a room or in adjacent connecting rooms and cause the toy to travel any desired course from one child, around and between obstructions, to the other child and then, upon the second child reversing the mechanism, cause the toy to reverse its direction of travel and return to the first child.

More specifically, my invention contemplates the provision of a novel automatic steering mechanism for a toy, for example, a toy automobile of the spring motor or other power driven type, the automatic steering mechanism including an element driven by the spring motor, which, in cooperation with suitable spaced selectively operable stops, causes the front wheels of the toy to be turned right or left and after each turn to automatically center themselves in accordance with the setting of the stops, whereby the toy may be set, prior to its operation, to travel a predetermined selected course.

Other objects and advantages of my invention will be more apparent from the following description when taken in connection with the accompanying drawings, in which:

While I have illustrated my novel automatic steering mechanism as being mounted in a toy automobile, it will be apparent that it is adapted to other uses such as in the various toys mentioned above. The toy automobile, shown herein, has the usual frame rear wheels l2, front wheels I3 and car body l4. As is usual in this type of toy automobile, a spring motor, adapted to be manually tensioned, is used to propel the toy. However, if desired, other types of motors may be used such as an electric motor adapted to be driven by current supplied from a battery. The spring motor consists of a flat, wound, ribbon spring l6 which has one end anchored to the frame of the toy through a stud and a suitable plate secured to the car frame, as indicated at H. The other end of the spring is anchored to a main shaft i8. The shaft i8 is suitably j ournaled in side plates I!) carried in the frame of the toy and has extending therefrom a key 2| by which, upon rotation of the key and shaft, the spring |6 may be tensioned.

Rigidly mounted on the main shaft I8 is a large gear 22 which meshes with a pinion 23 rigidly mountedonthe rear axle 24 of the automobile. The rear wheels |2 are non-rotatably mounted on the axle 24 so that rotation of the large gear 22 drives the rear wheels through the pinion 23. A releasable brake element 26, pivoted to the frame in the usual manner in toy automobiles of this character, is adapted to engage one of the rear wheels |2 so as to prevent the rear wheels from turning and retain the spring. H5 in a tensioned condition after it has been wound. After the spring has been properly tensioned and it is desired toplace the toy in operation, the brake element 26 may be released which enables the tension spring l6 to .drive the toy through the gears 22 and 23 and the rear wheels l2. As is usual in toy automobiles of this character, to prevent the toy from being propelled too rapidly whenthe spring is highly tensioned and to cause the automobile to operate at a more or less uniform rate of speed, a governor is used. This governor, generally indicated by the numeral 21, may be of any suitable type not necessary to be shown or described in detail herein since the construction and operation of a governor suitable for use are well known in the art to which this invention applies.

Mounted on the shaft l8 and rotatable therewith is a pinion 29which meshes with a large gear' 29. The gear 29 is rigidly mounted on a shaft 3| suitably journaled in the side plates l9. As shown more clearly in Figure 5, the gear 29 is rigidly secured to the shaft through a collar 32. secured to the shaft by a pin 33. A flange 34 on the collar 32 is secured to the gear 29 through rivets 36. The collar 32 also serves to space the gear 29 from the side plate l9. Secured to the gear 29 by means of nut and bolt assemblies 31 is a disk 38. The disk is spaced from the gear 29 by washers 39. A collar'35serves to space the disk from the other side plate I91 Theratio of the teethof the pinion 28 to the gear 29 is chosen so that the large gear 29 will make a single complete rotation during the normal travel of the automobile determined by the capabilities of the spring I6. That is, when the spring |6 has been fully tensioned and the brake 26 released to cause the spring to propel the automobile, the ratio of the gears 28 and 29 to each other is chosen such that when the spring is completely untensioned the gear 29 will have rotated through one complete revolution.

Around the periphery of the gear 29 are located at spaced regular intervals, a plurality of apertures which register with corresponding apertures formed in the disk 38. Mounted in each pair of registering apertures, formed respectively in the gear 29 and in the disk 38, is a pin or push rod 4|. Each of the push rods 4| is appreciably longer than the distance between the gear 29 and the disk 38 so that when the push rods are centrally located with respect to the gear and the disk, they protrude at each end an equal distance beyond the outer faces, respectively, of the gear and the disk, as shown in the drawings. As more clearly appears from Figure 7, a spring 42 lying between the gear and the disk extends around and between the push rods, throughout the complete circumference of the gear, so as to frictionally, although releasably, retain the push rods in the centrally located position with respect to the gear 29 and the disk 38.

Mounted on a rod 43, carried in the side plates l9, are a pair of bell cranks 44 and 44, each having an arm 46 and an arm 41. Each of the bell cranks is loosely mounted on the rod 43 and has an aperture 49 near the end of arms 41 thereof adapted to receive a tie rod. The tie rods 5| and 52 are connected, respectively, at 53 and 54 to the opposite ends of a steering element 56. The steering element 56 has a hub, as shown more clearly in Figure 6, and is rigidly secured by a pin 59 to a vertical shaft 6|. The shaft 6| extends through a boss formed as a part of the frame H with respect to which the shaft may be freely rotate-d. A collar 62' serves to space the hub of the steering element from the boss of the frame. The shaft is rigidly secured to the front axle 63 of the truck, as indi cated at 64, and, at 66, is rigidly secured to a cross brace 61 which has depending arms 68 apertured to receive the front axle 63. The front wheels of the toy are loosely mounted on the front axle 63.

On the rod 43 is loosely mounted a plate 69.

The plate 69 has depending legs H and I2 through 19 for receiving the rod 43 extend. The rearward portion of the plate 69 has a depending part 13 on either side of which is provided a slot 14, forming edges 16, adapted to engage the arms 41 of the bell cranks 44 and 44. Suitable spacers 11 are provided along the rod 43 to space the legs H and 72 of the plate 69 from the side plates l9 and to space the depending legs H and 12 from the bell cranks 44 and 44'.

which the apertures The depending part 13 of the plate 69 lies between bell cranks and serves to space them from each other. An aperture 18 is provided in the forward end of the plate 69 for receiving aspring 1-9, the other end of which is secured, at 8 I, to the cross brace 61.

The bell cranks 44 and 4-4 are spaced apart a distance sufiicient that when the push rods 4| are centrally located with respect to the gear 29 and the disk 39, the gear and the disk may rotate freely without the ends of the push rods striking the bell cranks. However, this spacing is such and the position in which the arms 46 of the bell cranks extend is such that when one of the push rods lies out of its normal central position, as illustrated for example at 83 in Figure 2, the arm 46 of one of the bell cranks 44 or 44' will lie in the path of movement of the end of the displaced push rod. When the gear and disk have been rotated to a position such, for example, that the push rod 83 strikes the end 46 of the bell crank 44, the bell crank 24' will be rotated downward or in a clockwise direction about the rod 43, as viewed in Figure 3, causing the tie rod 52 to be pulled rearwardly and thereby cause the steering element 56 to rotate in a clockwise direction, as viewed in Figure 2. When the steering element 56 is rotated in a clockwise direction, the forward wheels I3 of the toy are turned so that the automobile is steered to the right. Immediately after the push rod 83 has rotated to a position such that it is out of engagement with the rearward end of the arm 46 of the bell crank 44, the spring 19, which is continually urging the plate 69 in a clockwise direction, as viewed in Figure 3, causes the plate to be moved in that direction. The edge 16 of the plate 69 then pushes on the arm 47 of the bell crank 44' and restores the bell crank 44 to its normal position. Restoration of the bell crank M to its normal position restores the bell crank 44, which has been displaced forwardly by the movement of the steering element 56, to its normal position. The above described action restores the forward wheels l3 of the toy to their normal straightened position. It will be appreciated that a left-hand turn is made when a push rod has been displaced from its centrally located position in an opposite direction from that indicated by the position of the push rod 83. With a push rod in this displaced position it will strike the bell crank M and cause the steering element to rotate in a counterclockwise direction, as viewed in Figure 2.

When one of the push rods, such as the push rod 83, has been moved out of its centrally located position, the automobile is turned through a predetermined angle. This angle, for example, may be made 10 or 15 degrees, more or less, depending upon the length of time during which the arm 46 of the bell crank is in engagement with the push rod. The interval of engagement may be readily varied by varying the length of the arms 46 of the bell cranks 44 and 44. When two adjacent push rods are displaced in the same direction from their normal centrally located position, the automobile will make a turn through an angle approximately double the amount of that when only one push rod is in displaced position, so that; the toy will turn through an angle of approximately 20 to 30 degrees. It will, therefore, be apparent that the automobile may be caused to turn, within reasonable limits, through any desired angle. It will now be appreciated that the toy may be caused to travel a predetermined selected course and will make rightand left-hand turns through the desired angle all in accordance with the position at which the push rods have been set. I

In playing with the toy, the child will naturally become familiar with the approximate distance through which the toy will travel during the time when successive push rods pass the ends of the bell cranks, that is, the distance of travel represented by the spacing of adjacent push rods. The

child will then be able to set the push rods so that the toy will make rightor left-hand turns at the desired time and through the proper angle to avoid striking furniture or other obstacles adjacent the path which the child desires the toy to travel. However, in usual practice, the toy may be set more accurately by moving the toy over the desired course, while under manual control although under the power of the spring motor, and when the toy reaches an obstacle set the proper push rod or rods for causing the toy to steer to avoid the obstacle. That is, the child may tension the spring and while holding his hand on the automobile permit it to drive the toy and move it through the path he desires it to take. At each turn which he desires the toy to make, the child will push the proper push rod which, at that point in the rotation of the gear and disk, is adjacent the bell crank. After the toy has been moved through the desired course under manual control and the push rods are in the desired positions, he may retension the spring, return the toy to the starting position and cause the automobile to travel the course which has been previously mapped out.

In order to facilitate the setting of the push rods, I have provided a pair of push rod operating elements 88 and 89, each having a suitable finger piece SE. The push rod operating elements extend through apertures formed in the frame and the side plates it! into a position such that the ends thereof may be pushed into engagement with the ends of the push rods as they are successively presented to such action upon rotation of the gear. A pin 92 is rigidly secured to each of the operating elements 38 and 89 and a spring 93 is interposed between each of the pins and the side plates IE to restore the operating elements 88 and $9 'to their normal positions after they have been operated. By means of the operating elements 88 and 8 :7, the machine may be set while it is on the floor without turning it up side down each time a push rod is to be displaced. It will be observed that the push rod operating element, opposite the one which is actuated to set a push rod, is engaged by the end of the push rod being displaced so as to limit the movement of the push rod.

Suitable means are also provided for facilitating the selection of the push rods to be operated if it is desired to set the toy to travel a desired course by estimate rather than by actually moving the toy over the desired course under manual control during the setting of the push rods as described above. On one end of the shaft 3! is secured an indicating arm 96 and on the outside of the car body are provided a plurality of marks 91, indicating the position of the push rods. The marks may, if desired, be numbered to indicate feet of travel of the toy.

Assume that the position of the indicating arm 96, shown in Figure 1, is the starting position when the spring is fully tensioned. It will be appreciated that if it is desired to cause the automobile to make a turn after it has travelled a distance from the starting position measured by the spacing of, for example, four push rods, the child will lift the rear wheels off the floor and permit them, together with the gear 29 and the disk 38, to rotate until the indicating arm 96 has moved to the fourth mark 9! on the car body, after which the desired one of the operating elements 88 or 89 may be pushed in to move the desired push rod from its centrally located position. After the first push rod has been I to set, the rear wheels may again be permitted to rotate to the next position where a turn of the automobile in one direction or the other is desired, and another push rod set by pushing inward on one of the operating elements 88 and 89. In this manner, the gear 29 and the disk 38 may be rotated, while the wheels are off the floor, until the spring is completely untensioned and the push rods have been positioned as desired to cause the automobile to travel the desired course. After the push rods have been positioned, the spring may be retensioned and the automobile will travel the course for which it has been set.

In Figures 8 and 9, which are views looking at the bottom of the toy, I have shown a means by which, if desired, the push rods may be all returned to their centrally located position automatically. Secured in the side plates I9 is a rod 98 upon which are pivotally mounted arms 99 and 99. The arms 99 and 99' have cam portions I9I and a crosspiece I92 connecting the arms. A pin I93 is secured in the side plates I9 and normally supports the arms 99 and 99 in the position shown in Figure 3, in which position the pin I93 is in engagement with notches I94 formed in the arms 99 and 99. When the toy is inverted, the arms 99 and 99 pivot about the rod 98 so that the arms lie in the position indicated in Figure 9, with the cross piece I92 resting on the disk 38 which, it will be noted, is slightly larger indiameter than the gear 29. When the spring is tensioned while the toy is right side up and permitted to unwind while the toy is off the floor and in an inverted position, the push rods will strike the cam portions I9l of the arms 99 and 99 as the gear 29 and the disk 38 rotate and be automatically centered.

In Figure 10, I have illustrated how my automatic steering mechanism may be applied to a toy boat, generally indicated by the numeral I96. The tie rods I 91 and I98 correspond to the tie rods 5| and 52 and are connected to a steering element I 99 whcih is rigidly connected to a shaft III. The shaft III is adapted to be rotated by the tie rods I91 and I98 through the steering element I99 and is'rigidly connected to the rudder I I2 of the toy boat. It will, of course, be understood that the boat is equipped with propelling means of any suitable character and that the tie rods are operated in a manner similar to that described above.

In Figures 11 to 15, inclusive, I have shown a modification of my invention wherein the spring motor I6 drives the gear 22 which, in turn, drives a; pinion mounted on the rear axle I I3. The rear axle II3 has a bevel gear II4 mounted thereon which meshes with a bevel gear H6 rigidly mounted on a shaft III. A saddle II8 has depending arms II9 and I29 in which the shaft II! is suitably journaled'so that it may be rotated by means of bevel gears H4 and H6. The shaft II! is threaded throughout its length to receive a driven cam element I2I. The cam element has projections I22 which are in engagement with and ride along the lower surface of the saddle I I8. When the shaft II! is rotated, the cam element -I2I is caused to advance along the shaft 'III. It will be understood that the travel of the'cam element is such that the spring is completely untensioned when the cam element has moved from one end of the shaft II I to the other.

Plvoted or cradled in the lower end of the dep'ending arms H9 and I29 of' the saddle I18 is a plate I23. A plurality of push rods or stops I24 are mounted on the plate I23 and are retained in position by a 'T-shaped retaining plate I23 held in position by means of screws I21 which extend into the plate I23. A piece of friction material I39 is interposed between the retaining plate and the bottom surfaces of the stops I24 so that when the stops are placed in the desired position, they will not accidentally slide out of position. Each of the stops I24, at the ends thereof, has upwardly extending arms I28 and I2! which, at their upper extremities, may be slightly rounded. The driven cam element has cam portions I3I and I32 which lie above the plate I23 and extend beyond the'side edges thereof, as shown more-clearly in Figure 12.

-The stops I24 are capable of being moved, as indicated in Figure 12, so that the upper extremities of the arms I28 and I29 lie in the path of movement of the driven cam element I2I. When either the cam portion I3I or the cam portion I32 strikes, respectively, either the extremity of the arm I28 or the extremity of the arm I29, the plate I23, together with the entire stop assembly, pivots or cradles in the depending arms H9 and I29 of the saddle II8, as shown more clearly in Figure I3. Pivotal movement of the plate I23 causes operation of the steering mechanism now to be described.

While the steering mechanism per se may be similar to that shown in the first form of my invention, I have shown a modified form of steering mechanism adapted to be operated by the cradling movements of the plate I23 in the saddle IIB. Rigidly secured to and depending from the forward end of the plate I 23 are a pair of arms I33. A rod I34 extends through the arms, as more clearly shown in Figure 13, and protrudes beyond the arms an equal distance on opposite sides of a center line through the axis of theplate I23. Secured to the opposite ends of the rod I34 are a pair of cables I36 and I3! which extend upwardly from their points of attachment to the rod I34 and are then passed over pulleys I38 suspended from the lower side of a portion ofthe frame of the toy. The other ends of the cables extend forwardly and are secured to a depending portion I39 of a cross member I4I which is similar to the cross member 61 of the structure shown in Figures 1 to 9', inclusive. The cross member has depending portions which are secured to the front axle 93 of the toy.

A shaft I42, which may take the form of a headed bolt, extends through the under side of the crOss member MI and the cross member pivots with respect to this bolt. A U-shaped plate I43 has its upwardly extending portions I44 riveted to the lower side of a portion of the frame of the toy, as indicated at I49, and has its central portion I41 facing upon the upper side of cross member MI. The bolt I42 passes through the U- shaped plate and a nut I48, threaded on the end of the bolt, retains the assembly so that the cross member I4I may pivot with respect to the U- shaped plate I43. A spring I49 is coiled around the lower end of the bolt I42 below the cross member I4I, as indicated at I5I, and has its ends extending across the front of the toy beneath the cross member. The extremities of the spring I49 are turned upwardly, as indicated at I52, and these upwardly turned portions normally engage the rearward side edge of the cross member and downwardly turned portions I53 which are part 'of the frame II of the toy. The downwardly turned portions I53 of the frame constitutestops for limiting the movement of the spring.

When one of the cables I36 or I31 is pulled rearward by reason of the cradling movement of the plate I 23 in its saddle, the cross member Isl is pivoted about the bolt H12 in a clockwise or counterclockwise direction depending upon the direction of the cradling action of the plate I23. When the cross member pivots, for example, in a clockwise direction to cause the toy to make a right turn, as indicated in dotted lines in Figure 14, the upper end of the spring, as viewed in Figure 14, is carried by the cross member away from the depending portion I53 of the frame. As soon as the cam member I2! has ridden past the displaced stop which has caused the plate 123 to cradle, the spring I419 will restore the cross member MI to its normal centered position, in which position the front wheels of the car are straight and will restore the plate I23 to its normal centered position in its saddle through the cables.

It will now be understood that although the structure of the toy described in this modification is somewhat different than that of the structure shown in Figures 1 to 9, inclusive, the mechanism is adapted to accomplish the same general result. The stops I2 3 are shifted either right or left from their normal centered position with respect to the axis of the plate I23 in accordance with the path of movement which it is desired that the toy shall travel. As the driven cam element I2 I moves along the shaft IE1, the cam portions I3! and I32 thereof engage, one by one, the upstanding arms I23 and I29 of the stops 12 i, and the plate I 23 is thereby successively rocked in its saddle 1 i8. Depending upon whether the stop which engages the driven cam element I2I is in a right turning position or a left turning position, the front wheels of the toy will be turned by the pull exerted on either of the cables 135 or I31 to cause the toy to turn right or left in accordance with the setting of the stops. As soon as the desired turn has been made, the spring its will restore the front wheels to a straightened condition until the driven cam element, in the course of its travel along the shaft I18, strikes the next displaced stop.

It will be understood that the stops may be set either by causing the toy to travel over the desired course under manual control and setting the stops as the turns are reached in accordance with the position of the cam driven element, or they may be set by estimate as described in connection with the structure of Figures 1 to 9, inclusive. It will be particularly noted that the stops in this modification are more accessible than in the first structure described because they are located in a horizontal plane below the car body. It is, therefore, possible to set the stops while the driven cam element is stationary, that is, when setting the stops by estimate, the child may invert the toy and when he wishes the toy to turn right at approximately the distance from the starting point which he estimates will be about reached when the cam driven element is over the fourth stop, that stop is readily accessible without untensioning the spring motor as is necessary when setting the stops in the case of the first modification. It will further be understood that the toy may be caused to make a small or large angle turn. or two or more adjacent stops are displaced in the same direction fron their normal centered position, the toy will be caused to make a sharp turn and, if desired, by displacing a number of successive stops in the same direction, it is possible to cause the toy to travel in a circle.

In Figures 16 to 19, inclusive, I have shown another modification of my invention. The spring It, through gears 22 and 23, drives the rear axle 25 upon which the rear wheels I2 are mounted. On the shaft I8 is mounted a sprocket I61 which is connected by a suitable chain I62 to a sprocket mounted on a shaft I63 journaled in the frame of the toy. A pinion I6 1 rigidly mounted on the shaft I63 engages the teeth I65 of a rack I61. The lower face of the rack I 61 has a longitudinally extending projecting guide I68 which fits in a groove I69 formed in a track member MI. The track IN is carried by brackets I12 suspended from the frame of the toy. The rack is made of a length such that it moves substantially its entire length during the unwinding of the spring. Suitable pins or push rods I13 extend through apertures formed in the sides of the rack I61 and project, when in their centrally located position, an equal distance on each side of the rack. Loosely pivoted on a cross rod 11%, secured in the frame of the toy, are a pair of pivot arms I18 and I11. To the upper ends of the pivot arms are secured a pair of cables I18 and I19 which are secured to the front cross member of the toy in the same manner as in the modification shown in Figures 11 to 15, inclusive. The steering mechanism per se of this modification is the same as that described in connection with the structure shown in Figures 11 to 15.

The operation of the toy above described is essentially the same as that of the structures described in the first two forms of my invention. It will be understood that the spring motor, in addition to propelling the vehicle, drives the chain I 62 which, in turn, through the pinion 1B4, drives the rack I61. When the rack is moved and certain of the push rods I13 are displaced from their normal centrally located position, the displaced push rods will strike either the pivot arm I15 or the pivot arm E11, depending upon whether they are in a right or left-hand turning position. The pivot arms I15 and I1, through the cables, will then cause the toy to be turned in accordance with the setting of the push rods. The spring I49, after the toy has completed its turn, will straighten up the wheels and restore the pivot arms I15 and I11 to their normal positions.

In this modification of my invention, I have shown a means whereby, after the toy has travelled through a previously set course, the mechanism. may be reversed, the spring retensioned and the toy caused to retrace its course and return to its starting position. This is accomplished by providing means for enabling the rack I61 to be readily removed from the toy and reversed end for end. When thus reversed and the toy starts to retrace its course where it made a right-hand turn due to the displacement of, for example, the third push rod I8! from the end of the rack it will, when retracing its course, make a left hand turn, the push rod I8! then being the third push rod from the beginning of the rack. It will be appreciated that removal of the rack and the reversal of it end for end causes a complete reversal of the location of the displaced push rods so that the toy will retrace its course and return toits starting position.

To facilitate removal of the rack from the track Hi, the ends of the rack are provided with pivoted stops I82. When it is desired to remove the rack from the toy, the stops may be readily pivoted to the dotted line position shown in Figure 19 after which the rack may be slid rearwardly out of its track, reversed and slid back into position. After .the rack has been replaced, the stops I82 may be returned to their normal vertical positions shown in Figure 19.

With the reversing mechanism thus described, it is possible for two childrento play with the toy at opposite ends of the room or even in a position Where they cannot see each other, such as in adjacent or connecting rooms. The children may set the push rods to cause the toy to travel the desired contemplated course between them, around and between obstacles. After the course has been completely mapped out, one child at the beginning of the course, upon tensioning the spring motor, may cause the toy totravel the predetermined course to the second child. The second child may then reverse the rack end for end, as above described, retension the spring motor and cause the toy to retrace its course and return to the first child. It will be appreciated that, if desired, means may be provided in the first two forms of my invention for reversing the push rod carrying elements to enable the above described action.

While I have shown and described various modifications of my invention, it will be apparent that there are a number of ways by which the described result may be accomplished. I have merely shown and described the modifications shown herein by way of illustration and as being probably the most practical ways, from a commercial standpoint, of accomplishing the desired result. It will, however, be apparent that if an electric motor, operated by current supplied from a battery, is substituted for the spring motor shown and described in this application, the steering mechanism for the toy may be operated by current supplied from the battery. For example, a travelling unit may be driven from the rear wheels of the toy in a manner similar to that of the driven cam element or travelling unit of the second form of my invention. The travelling unit would be provided with two contacts elect ically connected to the battery which would be adapted to engage, respectively, a series of right and left-hand turning displaceable contacts, movable into and out of the pathof movement of the contacts of the travelling unit. Therighthand turning contacts would be electrically connected to an electro-magnet adapted to turn the front wheels right while the left-hand turning contacts would be electrically connected to a second electro-magnet adapted to turn the front wheels left. As the travelling unit passed over the displaced contacts it would; in succession, engage the displaced contacts and complete the circuits from the battery'to the electro-magnets, thus causing the toy to travel the course for which the displaceablecontacts have been set.

Since various'modificationsand changes may be made in the structure of my invention without departing from the principle thereof and in the form and relation of parts, I do not desire to be limited to the specific forms shown and described in this application, but include within my invention equivalents of the structure shown and described herein which are within the scope of the appended claims.
