TRANSMITTINGMOT'ION.

SPECIFICATION forming 'part of Letters Patent No. 273,982, dated March 13, 1883.

Application led February 1, 1883. (Model.)

To all 'whom it may concern:

Beit known thatl, LOUIS D. GOODWIN, a citizen ofthe United States, residing at Manchester, in the county of Hillsborough and State of New Hampshire, have invented certain new and useful Improvements in Devices for Transmitting Motion and Increasing the Power of Motors; and I do hereby declare the following to be a full, clear,and exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same.

`This invention relates to an improved machine or apparatus for converting motion; and it has for its object to increase the power derived from any motor, as more fully hereinafter specified. This object I attain by the means illustrated in the accompanying drawing, in which is represented a perspective View of my apparatus, a portion ofthe frame of which rock-shaft, near each end, are secured the me-y tallic segments 0,011 other equivalent devices, which are provided with apertures 1,),preferably screw-threaded, by means of which the connecting-rods for operating machinery may be attached to them. In the present instance two of such rods (indicated by the letter E) are employed, which are loosely connected to said segments by means ot the wrist-pins F. The

said rods at their lower ends are connected to i the wrist-pins Gon lthe cranks H of the shaft I, which is jonrnaled in pillow-blocks K, suitably supported. The said shaft has mounted upon it a fly-wheel, L,'and driving-wheeLM,

for the purposes hereinafter specified.

The letter N indicates two parallel bars, secured to the rock-shaft by means of the metallic straps P, or in any otherconvenient manner, and thesaid bars are braced by means of a transverse bar, R, secured at its ends to the segments above mentioned.

To the lower ends of the bars N is secured a crossbeam, S,and to the said beam is se cured a connection, T, which has loosely coni nected to it a pitman, U, which receives a rep p wrist-pins on the cranks of the shaftI beyond the dead-center, thus aiding in securing a uniformity of motion and in making' the machine yield a greater amount of power, this result arising from the well-known fact that a heavily-weighted pendulum will require more power to halt it in its oscillation than one less heavily weighted.

The amount or degree of power exerted by my improved apparatus over and in excess of the amount received from the operating motion is regulated to a more or less extent by changing the distance between the center of the rock-shaft and the point of attachment of the connecting bars or rods to the segment. This change, which is equivalent to a change of the length `of the shorter arm of a lever, necessarily effects or causes a change in the length of the swing or travel of the oscillating bars. curedat theirnpper ends to the segments, at a point to either side of the rock-shaft, the shaft I will be found to make butone revolution during the travel of the oscillating bars from a vertical position to one extreme of the arc of their oscillation to the other extreme of said arc, and back again to a vertical position; but when the connecting bars or rods (which are shorter or longer, as the case may be, than those above alluded to) are secured at their upper ends to the segments or their equivalents, at a point either above or below the cen ter of the rock-shaft, the shaft Iwill be found to make a revolution during the travel of the oscillating bars through one-half only of the arc of their oscillation, or, in other words, during their travel from a vertical position to one extreme of said arc and back again to a vertical line.

Having thus fully described my invention, what I claim, and' desire to secure by Letters Patent, is-

1. In a machine for converting and increasing power, the combination, with one or more oscillating bars, of a `revolving shaft, and means for connecting the saidbars and shaft,

When the connecting-rodsiare se whereby the oscillating motion of the former is converted into rotary motion and transmitted to the latter in increased degree, substantially as specified.

2. In a machine for converting and increasing power, the combination, with one or more oscillating bars having means which constitute a shorter arm extending from said bars, of arevol vin gshaft and connectingrods,where by the oscillating motion of the said bars is converted into rotary motion and transmitted to the shaft in an increased degree, substantially as specified.

3. The combination', in a machine for transmitting and increasing power received from a suitable motor to various machinery, of a roel;- shaftjournaled in bearings mounted upon a suitable frame, the segments mounted on said shaft, the oscillating bars attached to said rockshaft, and provided with a cross-beam at their lower ends, which may be connected to the pitman of a suitable motor, andthe connectingrods, connecting with the cranks of a drivingshaft, the Whole arranged to operate substan-4 tially as specified. 4. The combination, with the oscillating bars secured to the rock-shaft, of the Weights adapted to be attached to the cross-beam to thelower ends of said bars, substantially as and for the purposes specified.

In testimony whereof l affix my signature in presence of two Witnesses.

LOUIS DAVID GOODWIN. Titnessesz FRED. G. HALL, F. D. Rioux.
