Letters Patent No..107,474,

'dated September 20, 1870.

IMPROVEMEN'I'.l IN MECHANICAL HAND-MOTORS.

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

I, HARVEY FOWLER, of the city ot' Washington, District ot' Columbia, have invented an Improved Mechanical Handb-Toter, of which the following is a specification.

rlhis invention consists in the use of weighted levers or pendulums, in connection with elastic suspensory cords, made of coiled springs or otherwise,

machinery.

lu the accompanying drawing- Figure 1 is an isometrical perspective view, and

Figure 2, a side view of the -several parts in an- A is an oscillating vertical standard, pivoted at or near its foot, and supported upon a plattbrm, or otherwise.

B is a swinging weighted lever or pendulum, sup-` ported on the pivot b, near the top of the standard A, Of such or similar weighted levers there may be two, one on each side of the standard A.

From the weighted part W of the lever B an elastic cord, c, (which may be substituted with 'a coiled spring, having a rod or rope running through it, protected with a sheath, if necessary, 13)' passes up to a point of support, P, above the point upon which the pendulum swings.

Pivoted t0 the shaukof said pendulum, near the weight 'W, at d, is a handle, D, extending horizontally, and having a claw, a, for grasping the suspensory cord, if desired, for the purpose of communicating, by the hand of an operator, a swinging motion to said pendulum.

Also pivoted or hinged to said standard A, either at its foot, below' the pivot upon which it stands, or at some point abovesaid pivot, is a shaft or pitman, E, extending to and connected with a crank, H, for the purpose of g driving-wheels o f acar or carriage. v

To lessen the force necessary to be applied to the handle D, the weighted arm V may be attached to the clawv a, as shown in tig. 1.

Vhat I claim as my invent-iemand desire to secure by Letters Patent, is

l. The combination of a weighted swinging lever orvpendulum (supported upon an ,oscillating standard or arm of the same) with an elastic suspeusory cord,

said cord being attached to a support above the axis of the said pendulum, and connecting the weighted portion thereof with said point of support, thus constitut-ing 'a second support for said Ipendulum, substantially as and for the purpose described.

2. The elastic coil-spring, or equivc lent device, in combination with the pendulum, substantially as and for the purpose described.

'3. The combination of a vertical weight with a hinged handle, said handle having a claw, to take holdy of the suspensory cord connected with the pendulum, substantially as and for the purpose described. f
