July 6, 1937. .1. CHAPMAN ECGENTRICALLY PROPELLED SKOOTER Filed July 9, 1936 GUM 1 Patented July 6, 1937 UNITED STATES PATENT OFFIQE ECCENTRICALLY PROPELLED SKOOTER Application July 9, 1936, Serial No. 89,861

1 Claim.

This invention relates to a skooter and it aims to provide a novel construction wherein a perthe body or board thereof and the propelling wheel.

The more specific objects and advantages will become apparent from a consideration of the description following taken in connection with accompanying drawing illustrating an operative embodiment.

In said drawing:-

Figure 1 is a view of the improved skooter in side elevation;

Figure 2 is an inverted plan view thereof;

Figure 3 is a front elevation, and

Figure 4 is a detail section taken on the line 44 of Figure 1.

Referring specifically to the drawing wherein like reference characters designate like or similar parts, the skooter is provided with a body at IU, of any suitable material, preferably somewhat elongated as shown. Adjacent the front of the skooter and beneath the same, an axle H is secured to an upright steering post I2 and equipped with a pair of ground wheels l3, suitably journaled on the axle. The upper end of steering post I2 is provided with a handle bar IF.

A ground wheel I4 is provided at the rear of the board being the propelling wheel which has a central disc or body structure l5 through which an axle or bolt l6 loosely passes and is journaled. It will be noted that the bolt I6 is disposed eccentrically of the rear wheel l4 and that it is detachably connected in arms I! by means of nuts IS on the axle. The arms I1 are preferably angle iron, disposed in spaced apart parallel relation and bolted as at 20 to the rear end portion of the board H).

A fender 2| may be disposed over the rear wheel I4, having its forward end fastened as at 22 to the board I!) and having its rear position supported by a U-shaped bracket 23 straddling the wheel and bolted as at 24 to the arms IT.

The previously mentioned connection l2 comprises a handle bar, rigid with the axle and journaled at 25 in the board l0, extending to any suitable height for operation. Undue swing movement of the axle II is prevented by abutment thereof with stops as at 26 and to permit maximum movement of the wheels [3, the body is preferably notched at its sides as at 21.

A suitable bracket 28 is bolted at 29 to the body or board l0 and fastened to the top thereof as at 30 is a fender or shield 3| preferably extending over the front wheels [3, it being clear that the shield 3| has an opening therethrough through which the steering post l2 passes.

The wheels l3 and I4 are preferably of the pneumatic tired type.

In operating the vehicle the rider starts the device and stands on the forward end of the board or body l0, grasping the ends of the handle bar I 2 The weight of the rider will cause the wheel M to rotate because of the eccentric connection of the bolt at IS with the arms ll, the rider shifting his weight to his toes during the upward and forward movement of the eccentric connection, and back on his heels during the downward and rearward movement thereof. It has been found in practice that this action of shifting the weight of the body forwardly and rearwardly will tilt the board It) at one end and then the other, causing the eccentric means to operate the wheel I4 and thus propel the skooter.

Movement or propulsion of the skooter is readily braked by shifting the body rearwardly a distance sufiicient to prevent rising of the body at the rear end under the load of the occupant, thereby arresting motion.

Various changes may be resorted to provided they fall within the spirit and scope of the invention.

I claim as my invention:

A skooter of the class described having a body, ground wheel means therefor, arms extending rearwardly from the body, a second ground wheel means, an axle eccentrically connecting the arms and second ground wheel means, said first mentioned ground wheel means comprising two wheels and an axle, and a handle bar rising from the axle and pivotally mounted in the body, a bracket on the body, a shield mounted by the bracket extending across the said wheels and through which the handle bar rises, a U-shaped bracket secured to said arms, and a fender secured to the last mentioned bracket and disposed over the second ground wheel means.

JOHN CHAPMAN.
