10 Claims. (01. 46206) This invention is intended to simplify the Features include a longitudinally split body with mating portions forming axle bearings and the use of the body as a frame for the parts of a spring motor. Further objects and advantages appear in the specification and claims.

In the drawing, Fig. 1 is an exploded view of a spring motor driven toy; Fig. 2 is a front view, and Fig. 3 is a bottom view.

.In the drawing is shown a toy automobile having a body of molded plastic longitudinally split into upper and lower sections l and 2. The upper section, which has the body contour corresponding to the desired type of vehicle, has depending side walls 3, 3a which upon assembly abut and are cemented to upwardly extending side walls 4, 4a on the lower body section. The lower section has a bottom wall 5 which completely encloses the underside of the vehicle except for slots 6 through which wheels 1 project. Both sections are adapted to molding from plas- If desired, a two toned effect can be obtained by using different color plastic for the upper and lower sections.

The wheels I are carried on front and rear axles 8 and 9 each having stub shafts or journals 10 which in the assembled position bear against or are confined between bosses II on the side walls 4, 4a. On the inner surface of the bosses II are projections I2 abutting projections l3 depending from the walls 3, 3a. The abutting edges of the projections l2 and I3 have mating semicircular bearings M for the journals iii. In assembly, the journals I are .positioned in the bearings I4 in the projections l3 on either the upper or lower body'section and as the sections are secured together, the wheel axles are both located and journaled in the body. The assembly is facilitated by the fact that the outer surfaces of the projections l3 bear against and are guided on the inner surface of the bosses II.

The toymay be driven by a spring motor comprising a key shaft and an idler shaft It. The key shaft has a key IT, a gear is, and an arbor I3 to which is suitably anchored one end of a coil spring 20. The idler shaft'has a pinion 2| meshing with the gear I 8 and a gear 22 meshing with a pinion 23 on the axle 9.

The key end of the key shaft 55 projects through a slot 24 in wall 3a of the upper body section and is journaled in a semicircular bearing surface 25 at the bottom of the slot and a semicircular bearing surface 26 in the upper edge of a projection 27 on the lower body section. In

projection a. parts are now positioned in the upper body secthe assembled position, the projection 21 overlaps the inner edges of the slot 24. At the opposite end of the key shaft is a journal 28 received in mating bearing surfaces 29, 30, respectively in the edges of a projection 31 on the lower body section and on a projection 32 on a boss 33 on the inner surface of wall 3 of the upper body section. The outer surface of the projection 29 is guided on the inner surface of the boss 33 during assembly.

The free end 34 of the spring 20 is hooked over a pin 35 integral with a projection 35a depending from the upper body section. Upon assembly, the pin is received in a hole 36 in a projection 3'! extending up from the lower body section. After assembly of the body sections, the free end of the spring 20 is securely anchored to the body.

The idler shaft i6 has at its ends journals 38 received in inclined slots 39 formed by mating notches 40, 4| in projections 40a and Ma projecting from the upper and lower body sections. The spring tension urges the idler shaft to the upper ends of the slots 39 in which position the idler gear 22 meshes with the rear wheel axle pinion 23. When the spring tension is relieved, either by a winding force on the key I! or by running down, the idler shaft drops by gravity to the lower end of the slots 39 in which :position the idler gear 22 is clear of the axle pinion 23. This permits over-run or free wheeling of the toy and also eliminates the need for a ratchet =in the motor gear train. In the assembled position, the slots 39 are not visible and the idler axle is both journalled and confined between the vehicle body side walls.

In one method of assembly, the upper body section is inverted; the front and rear wheel axles are dropped into bearings M on the projections l3; the idler shaft is dropped in slot forming notches 40 in the projections 40a; the key shaft is dropped in the slot 24 and the hearing 23 on projection 32; and the free end 34 of the spring 23 is hooked over the pin 35 on All of the driving and driven tion. The lower body section is now brought into register with the upper body section and suitably secured thereto, for example by cementing the abutting edges. The toy now has all of its operating parts (except the key I?) enclosed within the body.

What I claim as new is:

- 1. Ina vehicle toy, longitudinally split upper and lower body sectionshaving respectively downwardly and upwardly extending registering side walls, an axle received between the body sections, said axle being short enough to be received within said side walls, whereby said side walls are unmarred by bearing holes for said axle, and projections on the inner surface of the side walls having mating edges forming a bearing for the axle.

2. In a vehicle toy, longitudinally split upper and lower body sections having respectively downwardly and upwardly extending registering side walls, an axle received between the body sec tions, said axle being short enough to be received within said side walls, whereby said side walls are unmarred by bearing holes for said axle, projections on the body sections having edges mating in the assembled position of the body, and notches in said edges cooperating to receive and locate an axle, said notches being within and having their ends enclosed by the body side walls.

3. In a toy, a lower body section having a bottom wall provided with wheel slots and upwardly extending side walls, an upper body section having a top wall providing the desired appearance and downwardly extending side walls registering with the side walls on the lower section, an axle over said wheel slots and having its ends ccnfined between the side walls, whereby said side walls are unmarred by bearing holes for said axle, and projections on the inner surfaces of the side walls having mating edges forming a bearing for the axle.

4. In a toy, a motor having a spring and gear shafts, a body section having side walls with shaft end' receiving notches, a complementary body section having portions cooperating with the shafts to hold the shafts in the notches, a projection on one of the body sections for receiving one end of the spring, and a cooperating projection on the other body section preventing removal of the spring.

5. In a toy, a motor having spring and gear shafts, mating parts split along the axes of the shafts, one of the parts having notches receiving the shafts and a projection receiving one end of the spring, and the other part having portions complementary with the notches and projection cooperating to journal the shafts and to anchor the spring.
