This invention relates toa new and improved device for transmitting motion or power from a spring to machinery to be driven or operated, and is more especially designed for operating portable or light Vmachines---such, for instance, as washing machines, churns, sewing machines, Svc.

The object of the invention is to obtain a compact, simple, and efficient device for the purpose specified-one which will not be liable to get out of repair or become deranged by use.

A represents a rectangular framing, which may be constructed in any proper manner to support the working parts, and B is a shaft,

which is placed transversely in the framing,

and has a toothed wheel, O, keyed upon it, into which wheel a pinion, D, gears, the latter having aratchet, a, at one side of it, with which a pawl, E, engages. On this shaft B there is placed loosely a toothed wheel, F, having a drum, G, attached, through which the shaft B passes loosely, and within this drum Gr there is a coil-sprin g, H, the inner end of which is attached toB and the outer end attached to the drum.

The drum Gr protects the spring H from dampness, and consequently from oxidation or rust, which would soon render it inefficient.

The wheel F gears into a pinion, I, on a shaft, J, which has a toothed wheel, N, upon it, the wheel N gearing into a pinion, O, 0n a shaft, P, which has a fly-wheel, Q, at one end and a crank, It, at the opposite end. The crank R has a pitman, S, attached to it, to which two levers, T T', are connected-one, T, by an arm, U-as shown clearlyin Fig. l. Either of these levers rmay be used as may be most convenient for transmitting the power of the spring to the machineryl to be driven.

The spring H is wound up by a crank, V, applied to the shaft of the pinion D, the latter, in connection with the wheel O, turning the shaft B and winding up the spring H.

The power of the spring H is controlled by a regulator constructed as follows: W is a rocking or oscillating frame, which works at its lower part on a center, b, and has an oblong slot, c, at its upper part, in which a wrist, d, at the end of a crank, M', on the shaft M works, and communicates motion to frame 4W. The outer ends of the lower part of the frame W have pendants X X attached to them by pivots e e, and said pendants work loosely through a plate, Y, which may be raised and lowered through the medium of a lever, Z, and retained at any desired height by means of a piu on said lever engaging withany of a series of holes in the framing A. (See Fig. l.) The pendants X X have spiral springs A' on them, and by adjusting the plate Y higher or lower the frame W may, through the medium of the spring A', be made to offer a greater or less resistanceto the shaft M. Thus by this simple means the power of the spring H is placed under the most perfect control.

The framing A, when being drawn from place to place, rests upon casters f; but when the device is in use it is raised, so that said casters will be free, or above the oorin g or ground, and the device rest upon feet g, which are at the ends of shafts h h, placed transversely under the framing. One of these shafts has a lever, B', attached. Said lever, near its lower end, is connected, by a rod, C', with an arm,

D', which is a continuation of the foot g at the.

opposite end of the device, but at the same side thereof as the lever B'.

In order to raise 'the device, so that the casters f will be off from or free from the licoring or ground, the lever B' is drawn backward, so that the lower end of thel feet g will movement of lever B. At an57 time when it is required to move the device from place to place the device is let down, so as to rest 011 the casters, by shoving the lever. B forward, as shown in red in Fig. 3.

Around the base of the framing1 A there is attached a molding, F, the upper surface of which is beveled, as shown at LX in Fig. 2, in order that oil or grease which may dropfrom the gearing Will be caught by said inclined surface ax and caused to run on the base instead of upon the floor, the surface ax inclinin g downward from its outer to its inner edge.

Having thus described myin ven tion, I claim as new and desire to secure by Letters Pat ent- 1. The combination of the oscillating frame YV, pendants X X, and spring A with the crank M', all arranged to operate as and for the purposes specified.

2. In combination with the parts above specified, the adjustable or rising-and-falling plate Y, for the purpose explained.

JOHN BRIZEE.
