dotted Letters Patent No. 97,837,-Zatel December 14, 1869.

IMPROVED vnnocmnnn. 4

The schedule referred to in these Letters Patent and making part0! the same.

-To all whom it may concern Be'it known that I, WILLiAMTOL bf Bulfalo, Erie county, New York, now temporarily residing at Toronto, Canada, have invented a new and iniproved Velocipedc; and I do hereby declare that the following is a full, clear, and exact descriptionthereof,

which will cnable others skilled in the art to'make and use the same, reference" being had to the accompanying drawing,ibrming part of this specifica -tion, in which- .liigurel'represents a vertical longitudinal section ofm y improved velocipcdc.

Figure .Z'is a plan-or top view of the same. Figure Sis a detail side view of the connected axles. .Siinilar letters of reference indicate corresponding parts. t

This invention relates to a new three-wheeled velocipcdc, which is so arranged tliat'thc driving-wheels, although mounted on separate axles, will make equal numbers of revolutions as long 4 be kept in a straight direction, while they can be disconnected when the device isto be turned in a circle. Theinvention consists in theapplication of a toothed wheel, which meshes int o pinion's on the separated axles, to connect the same, and which is hung on a pivoted lever, so that it can be readily thrown outv of gear when the axles are to be disconnected.

The invention also consists in the general combination of parts for imparting motion to the vehicle.

A, in the drawing, represents the frame of iny improved velocipedc. I v

B is the, drivers seatsupported thereon.

O O are the front driving-wheels, mounted on separate axles 1) D, that haveit-heir hearings in the frame 'A in front of the seat.

The axles I) I) are in line with'each other, and their inner ends are brought close together within the inner supporting-box a of the frame.

as the machine is to' Piuions b I) are mounted upon the contiguous inner ends-of the axles D.

E is a lever, pivoted to the frame A under the seat, and extending over the contiguous ends of the axles D.

A pinion, c, is hung on the end of the lever E, and 1 is, by a spring, (I, held in contact with both pinions b which it connects.

\Vhen the two axles I) are revolved by means of foot-levers F, or hand-levers G, or both, their motion will be equalized by the pinion c, which will-cause both wheels to make equal revolutions.

\Vhen the velocipede is to beturned ona curve, the lever E is, at its rear end, depresscdby' the foot of the driver, to raise the pinion c outof gear. Then one wheel, 0, can be kept stationary, while the other revolves.

The rear end of the frame A is supported on a caster-wheel, H, as shown.

The hand-levers G are pivoted to the frame, and

connect with rods 0, which embrace eccentrics f of the axles, as shown.

The foot-levers may be connected directly with cranks g of the axles.

Having thnsdescribed my invention,

What I claim as new, and desire to secure by Let-- ters'P-atent,is

1. The lever E, carrying the pinion o, and acted upon by the spring (I, when arranged to connect the pinions b on the ends of the axles D, substantially as herein shown and described, for the purposespecified.

2. The combination of the separate driving-axles D D, which carry the pinions I), eccentrics j, and

cranks g, with the lover ll, pinions c, levers F and G,

and rods c, all arranged and opera-ting substantially as herein shown and described.
