TOY.

APPLICATION FILED MAR. 22. I920.

Patented Nov. 28, 1922 Ema DAVID HEYMAN, F BBOOKLYN, NEW YORK.

Application filed March 22,

To all whom it may concern:

Be it known that 1, DAVID HEYMAN, a citizen of the United States, residing at '3rooklyn, in the county of Kings and State of New York, have invented certain new and useful Improvements in Toys, of which the following is a specification.

My present invention relates particularly to what are commonly known as wheeled toys and the special objects of the invention are to provide simple, inexpensive and etficient gearing for operating such toys.

The invention involves certain novel fea tures of construction and combinations of parts, as described in the following specification and broadly claimed in the appended claims.

A. structure embodying the invention is illustrated in the accompanying drawing, but as this embodiment is primarily for illustrative purposes, it will be understood. that the same is subject to modification and change without departure from the true spirit and scope of the invention.

I would also have it understood that the terms employed herein are used in a descriptive rather than in a limiting sense, except, however, for such limitations as may be imposed by the prior art.

In the drawing referred to, Figure 1 a perspective view of a miniature tank i n1 two gears is also provided for, by means of which the invention is incorporated.

Figure 2 is a bottom plan View of the same.

Figure 3 is a broken cross sectional view illustrating the gearing on a somewhat out larged scale.

Figltlre 4: is a detached perspective view of the bearing bracket.

The body 5 of the toy illustrated is made in simulation oi? the well known tank and is propelled by a pair of road wheels 6 carried by an axle 7 journaled in the side walls of the tank body near the forward end of the toy. The rearward end. oi the toy may be supported by suitable rollers 8 carried. by an axle 9 which, may be inclined. relative to the propelling axle, as shown, so as to cause the toy to travel in a circle.

Engaged on the axle 7 is a pinion 10 which is shown in this instance as niade iast to one of the road wheels. Both. the road wheels in this instance are fast on the axle, which is shown as of square or angular cross section, so that the rotation of the pinion will efiect the driving of both road wheels.

TOY.

1920. Serial No. 367,634.

The pinion is driven, in the construction illustrated, by a crown gear 11 mounted on a shaft 12 disposed substantially at right angles to the axle. This shaft is rotatably supported at its rear end in a bearing 13 provided in the rear wall of the tank body and is rotatably engaged at its forward end in a cup shaped bearing 14 provided inthe bearing plate 15. This bearing plate is in the form of a bracket loosely supported on the axle, it having for that purpose a pair oi rearwardly

bent lugs

16 and 17 perlo rated as indicated at 18 and 19 to loosely fit over the axle. This bearing bracket is held against such lateral displacement as would result in the disengagement oi. the teeth of the crown gear from the teeth of of the pinion by the engagement of the supporting

lugs

16 and 17 between the hub portion 20 of the one wheel and the pinion 10 of the other wheel.

Disengagement of the crown gear from the pinion in a direction at right angles thereto is prevented by a guard or stop overstanding the back of the crown gear. this guard is shown in the form of an arch 21 projecting to the opposite side of the bearing plate from the supporting lugs, having a rounded bearing lug 22 arranged to bear upon the back of the crown gear. 7

Positive engagement of the teeth of the an upstanding guard flange projecting toward the bearing lug 22 of the arch and arranged to engage inside the rim of the crown gear. The crown gear is thus in ct feet guided and held against the guard flange 23 at the front thereof and the hearing lug at the back thereof. This bracing and guiding of the parts, which are usually made of sheet metal. results in the mainte nance of the proper relation of such parts and enables the toy to withstand, hardv usage.

The bracket 15 also is usually constructed of sheet metal, in. which event, the bearing lug 16 may be turned up from one edge thereof and the guard arch 21. be turned. up from the opposite edge thereof and projecting in the opposite direction, the second.

bearing lug being cut out of the plate at the base of the arch and bent to one side, while the curved guard flange 23 is cut from within the arch and bent out toward the intermediate span of the arch.

In the construction shown, the crown gear has attached to it a drum or barrel about which there is coiled a spring 26 attached at its forward end at 27 to the drum and attached at its rearward end at 28 to a bracket 29 fast on the shaft. On the'forward end of the shaft there is provided a stop member 30 in the form of a ratchet disk arranged to engage with a holding tooth or pawl 31 struck from the face of the bracket 15. The rearward end of shaft 12 is shown provided with asuitable winding key.

From this construction it results that when the winding key is turned and the road wheels are held against rotation, the spring 26 will be placed under tension and the key shaft 12 will be held against. backward rotation by the engagement of the stop on the forward end thereof with the holding stop on the bracket. When the road wheels are released, the spring will assert its power to turn the barrel and crown gear attached thereto, which latter is in mesh with and operates the pinion on the axle.

My construction, it will be apparent, enables the parts to be assembled with accuracy and holds the parts in proper relation despite rough treatment. The teeth of the crown gear may ride over the face of the supporting bracket 15, this engagement further serving to maintain the parts in proper relation.

The cupping of the bearing 14 for the forward end of the key shaft prevents said shaft from contacting with the axle, as indicated in Figure 3.
