tween them, complete the
countershaft assembly. The clutch assemblies are of Frank Duryea's
design, having internal arms, expanding outward to press leather-faced
shoes against the inner surface of the drum, thus securing the drum and
its gear to the shaft. Behind this machinery is the jackshaft with its
small differential on the right, two laminated rawhide gears[33] meshing
with the iron gears of the countershaft, and the internal-gear sprockets
hanging on the small pinions at either end. A sliding cam bar, mounted
nearly in the position of the former shipper-fork carriage, is operated
by the vertical movement of the tiller handle to engage any one of the
three clutches. With the tiller depressed, the vehicle is in reverse.
Elevating it slightly puts it into low gear, and raising it still higher
runs the machine at its highest speed.

CHARLES E. DURYEA, OF PEORIA, ILLINOIS.

ROAD-VEHICLE.

SPECIFICATION forming part of Letters Patent No. 540,648, dated
June 11, 1895.

Application filed April 30, 1894. Serial No. 509,466. (No model.)

_To all whom it may concern_:

Be it known that I, CHARLES E. DURYEA, a
citizen of the United States, residing at Peoria,
in the county of Peoria and State of Illinois,
have invented new and useful Improvements 5
in Road-Vehicles, of which the following is a
specification.

The object of this invention is to produce a
road vehicle which shall be self-propelled, not
unduly heavy, simple and easy of control and 10
comparatively inexpensive, together with
such minor objects as will become hereinafter
apparent.

The invention more particularly relates to
the construction and arrangement of parts for 15
constituting the driving gearing and to the
means for controlling the action thereof; to
an improved manner of mounting the front,
or steering, wheels upon the front axle, and
of mounting the said
