FOOT-POWER.

BPECIFICATION forming part of Letters Patent No. 298,566, dated May 13, 1884.

Application filed February 21, 1884.

To aZZ whom. it may concern.-

Be it known that I, HENRY FIELD, J r., of New Bedford, in the county of Bristol and State of Massachusetts, have invented a new and Improved Foot-Power, of which the 'following is a full, clear, and exact description.

The object of my invention is to provide a new and improved foot-power to be used in place of the usual treadle-erank and connect ing-rod for operating machinery by foot.

The invention consists of the combinations of parts and their construction, substantially as hereinafter fully set forth, and pointed out in the claims.

Reference is to be had to the accompanying drawings, forming part of this specification, in which similar letters of reference indicate corresponding parts in all the figures.

Figure 1 is a side view of my improved footpower. Fig. 2 is a sectional elevation of the same on the line a: m, Fig. 1. Fig. 3 is a detail side view of the elbow-lover, the pintles being shown in section.

The standard A, united by top rods, A, and a bottom central shaft or rod, 13, form a frame. A foot-plate, G, is pivoted centrally to rock on and above the shaft or rod 13, and its ends are pressed upward by spiral springs D, held between the under side of the foot-plate O and the upper surface of a cross-bar, E, held on and below the shaft 13 by means of a bindingscrew, a, which permits of adjusting the bar E so as to be inclined more or less, according to the inclination of the foot-plate in its normal position. A11 upwardly-projecting bar, F, is loosely mounted at its lower end on the shaft B, and has a fork, F, formed on its upper end, from the outer edge of each prong of which fork apertured lugs or eyes (I 9 project, through which rods G pass, which project downward from the bottom of a curved longitudinal frame, I, in the opening of which a friction-wheel, H, is located, and mounted on the driving-shaft J, on which shaft a belt-pulley, K, or a combined belt-pulley and flywheel, is mounted. The wheel H is provided with a rubber rim, H. The diameter of the wheel H, including its rim H, is slightly less than the width of the opening in the frame I. Spiral springs L, surrounding the rods G, are

i held between the bottom lugs, 51, and nuts M, screwed on the rods, and press the frame I upward. The frame I is provided at the center of its bottom bar with a downwardly-projecting arm, IT, on the lower end of which the angle-pivot h of an elbow-lever, O, is held, the end of the upper arm of the said lever 0 being pivoted to one of the prongs of the fork F. The downward-projecting arm of the lever 0 is provided with a longitudinal slot, P, through which a pintle, Q, passes, which also passes through a longitudinal slot, R, formed in a standard, S, of the foot-plate G, the said pintle being provided with a nut, T, for locking it in place. The springs 0 press up the ends of the foot-plate O, and bring the same back to the normal position. The pressure of the rim of the wheel H can be regulated by adjusting the pintle Q higher or lower.

The operation is as follows: If the lower end of the foot-plate Gthat is, the end toward the operator-is depressed, the swinging part of the device is moved in the direction of the arrow a, and the standard S, which is independent of the arm F, swings the lower, end of the elbow-lever O slightly in the direction of the arrow a, thereby moving the anglepivot lb of the angle-lever O upward, thereby raising the frame I and bringing the contact with the rim of the wheel H, which is thus revolved by friction in the direction of the arrow 1). If the opposite or inner end of the foot-plate G is depressed, the swinging part of the device is moved in the inverse direction of the arrow a, and the upper end of the standard S moves the lower end of the anglelevcr O in the inverse direction of the arrow a, thereby moving the angle-pivot h of the angle-lever O and the frame I, connected therewith, downward, and bringing the bottom of the top bar of the frame I in contact with the rim of the wheel H, thus revolving the wheel H in the direction of the arrow 1). If the angle-lever O is pivoted to the other prong of the fork F, the motion is reversed.

claim as new, and desire to secure by Letters Patent, is

1. The combination, with a pulley or wheel,

inner edge of the bottom bar of the same in' Having thus described my invention, what I IOO of a rocking frame surrounding it, an elbowlever connected with the frame, and with a rocking standard, and of a rocking arm for holding the frame surrounding the wheel, substantially as herein shown and described.

2. The combination, with a pulley or wheel, of a rocking frame surrounding it, a rocking arm on which the frame is held in such a manner that it can have a slight vertical movement, and an elbow-lever pivoted to the frame, to the arm holding the frame, and to a rocking standard, substantially as herein shown and described.

3. The combination, with the wheel H, of the rocking frame I, surrounding it, and provid ed with downward]y-projecting rods G, the rocking arm F on the shaft B. the fork F, formed on the upper end of the arm F, in the prongs of which fork the rods G are held, the standard S on the rocking foot-plate G, and of the angle-lever O, pivoted to the lower end of an arm, N, vof the frame I, to the fork F, and to the standard S, substantially as herein shown and described.

4 The combination, with the wheel H, of 25 the frame I, having the downwardly-projecting rods G, and the arm N, the rocking arm F on the shaft B, the fork F on the upper end of the arm F, the springs L, the nuts M on the rods G, the angle-lever O, and the standard S on a rocking foot-plate, substantially as herein shown and described.

5. The combination, with the rocking footplate 0, of the cross-bar E, held on the shaft B and below the plate 0, and of the springs D, interposed between the foot-plate G and the bar E, substantially as herein shown and described.
