IMPROVEMENT m HOMOMOTIV'E.

The Schedule referred to in these Letters Patent and making part of the same.

The gear-wheel m is fixed to, or preferably forms a direct part of a pawl, or pawl-driven wheel 0, having To all whom it may concern:

Be it known that I, WILLIAM SMITH HALL, of Quincy, in the county of- N o'rfolk, and State of Massachusetts, have invented a Homomotive; and I do hereby declare that the following, taken in connection with the drawings, which accompany and form part of this specification, is a description of myinvention sulficient toenable those skilled in the art to practise it.

United States Letters Patent, No. 65,665, dated sides, with which flanges engage two clutch or frictionpawls, or gripes q.

Each of these pawls is hung at the end of a pawllever, r, fulcrumed and rocking freely on the shaft n, the opposite arm of the lever being attached to one end of a spring, z, whose other end is attached to the frame a, the stress of each spring returningits lever to normal position when released.

I Each pawl, or gripe is composed of two pins j,

projecting from an arm, 8, said arm having an oblong slot near its outer end, through which passes the screwpin t, by which it is hung to the pawl-lever, and the pins j j embrace the adjacent flange of the drivingwheel.

Each arm s is pressed in a direction opposite to that in which it moves in driving the wheel, by a slight spring, u, theslot enabling the arm to assume a position in direct line with the pawl-lever, or a position angularthereto.

When the spring u throws the arm into inclined position, the two clutch-pinsj hug the flange of the wheel,

covers a peculiar system of springpawl levers, ratchetand-pawl mechanism, and double set of treadle-levers, pawl-levers, 850., so arranged that the actuated wheel or shaft may be driven by either or by both treadles, and by any extent of movement of either or both, and my second patent (86,833) relates particularly to, and covers the combination of the invention shown in the ism, and the peculiar arrangement of a momentumwheel, and other details of the mechanism.

These inventions were designed for driving any light mechanisms capable of being advantageously operated by foot-power, and the peculiar organization shown in the last patent was designed by me with particular reference to the adaptation of the inventions to driving light vehicles by hand or by foot-power, or by both combined.

My present invention relates to this adaptatiom'and consists primarily in a carriage having this mechanism arm so inclined, the pins will carry the wheel with movement, while, if the movement of the lever be reversed, friction of the pins against the flange will bring will slip upon the flange, or the flange will run between the pinsavithout movement being imparted by them to the wheel, and without the pins impeding the free rotative movement of the wheel.

The mechanism thus described, for driving the shaft, is identical, in its general arrangement and method of operation, with that shown in my patent, 86,833, the upper arm of each pawl-lever in said patent being connected with a treadle, by means of which either pawl may be actuated singl or both together, the momentumwheel, on a shaft auxiliary to the pawl-driven shaft, actingas an accumulator of the power exerted in driving the treadles.

In the carriage, I joiht to the upper arm of each pawl-lever the rear end of a horizontal connecting-rod, '21, whose front end is jointed to a rocker-arm, w, hung on a cross-rod, x, in front of the dasher of the carriage. The arm swings freely on this rod.

To the endof each rocker-arm w is fixed a pedalbar, 3 which projects through a hole in the dashcrboard, and has, at its top, a pedal, z, preferably jointed ment;
