TO ALL WHOM IT MAY CONCERN:

Be it known that I, WILLIAM F. GOODWIN, of East New York, county of Kings, and State of New York, have invented a new and Auseful, Improvement in Mechanical Movements forA Multiplying and' Transmitting Motion vand Power,l to he used for' waters, clocks, and for all other purposes where motion is required to he multiplied for converting power into speed or speed into power; and I hereby declare the followingto be a full description of the'saine, reference being had to the accompanying drawings, which form a'part of this specification, and in whichy Figure 1 represents an outside view of one form of a 'case ordrurn in which myimproved mechanical movement may-he arranged and operated.

, Figure 2 is n.A vertical section'through the same, showing the arrangement of mechanism withinl the drum. Figure 3 is' a similar section through the same apparatus, showing the drum composed of separate apartments or sections, arranged to operate together. Y

Figure shows-a vertical and also a vtransverse section of the same -parts of the apparatus, showing two intermediate transmitting-wheels, mounted one at each end on one arm, and meshing with the same pinion.

Figure 5 shows a vertical and a transverse section of the same devices, showing the intermediate or" transmitting-wheels mounted on a toothed driving-wheel, which gears or meshes with a toothed wheel that enters the toothed drum from the outside, through a. cut or opening in the side of said drum.

Similar letters of reference denote corresponding parts in the several figures. e

This invention consists in the-novel construction andar'rangement of gear-wheels within an internallytoothed drum or case, mounted on short shafts, which are in a line and rotate on the same centre, and have their hearings in and are supported by partitions or ldiaphragms within said drum or case. The gearing may be described as follows:

Letter C is the main driving-shaft, Letters C102 O3 are short shafts or hubs, on eachof which a pinion `is mounted, and also an arm or toothed wheel, which carries an intermediate wheel or wheels onrthe end of the driving-shaft C, which terminates within the drum A, and is mounted in a tubular arm Qrbearing-sleeva. Attached thereto is an arm, D, rigidly connected toand turning with shaft-C, and provided at itsuter swing ing end with a short fixed stud or pivot, d, on whichfis mounted a transmitting-wheel, E, which gears with and receives its motion en stud d, from the toothed vdrum A. Said wheelE also gears with and communicates motionv to a pinion, F, keyed to a second shaft, C, which at one end has a. pivot hearing in the end of shaft C, and near its other end is supported in a diaphragm or partition, G, The end of shaft'C, extending through said partition G, isarlned with a fixed arm or crank, on the outer swinging end of which isa second transmitting-wheel- Ygearing with the drum A and with a second pinion, E, on a. third shaft or hub, C2. The lshaft C2 has a pivotal bearing at one end, in shaft Cl, and at its other end a bearing in as'econd 4partition or support, G1; The proj eeting end of shaft C2 has its arm and transmitting-wheel, for imparting motion from'the drum A, to a third pinion, F2, on afourth shaft, C3, the-bearings of which are arranged'in a. manner similar to those before described, and the same arrangement ofshafts and pinions may be continued to any desired extent, the last shaft or spini dle, or the series projecting through the end or head -of case A, as 4represented in the drawing. I

The drum or internal gear-case A, being supposedl to have (for the purpose of illustration) sixty teeth, and the pinons'iF vFl F2, &c.,`twelve teeth each, the operation ofthe gearing would be as follows:

The shaft C revolving, carries with it Vthe arm D, and the transmitting-wheel EA meshing with the? drum,

receives a rotary motion on its own shaft therefrom, which is communicated to the pinion F and jits shaft or huh' 10, in the same direction with the shaft C, thetwo shafts turning, together and in the same direction. Shaft Cl receives one revolution from shaft C, and the pinion F having, as stated, twelve teeth, and being driven through the transmitting-wheel E by the drum having sixty teeth, receives iive revolutions therefrom, the shaft C and pinion .F receiving, therefore, one revolution with and from the sha-ft C, and five revolutions from the druurA, 'have six revolutions to oneof'shaft O; consequently the arm D1, connected to and turning with shaft Cl, causes its transmittingfwheel E1 to traverse the cogged drum six times whilethe arm D'traverses said vdrum once. The pinion F is, consequently, acted upon six times' bythe teeth of the drum while the pinion F is operated upon once by said teeth, and the shaft Gzreeeiving one additignal revolution from and'with each revolution of the shaft C1, the pinion F1 and its shaft C2 have imparted to them six revolutions to one of shaft CZ and pinion F, and thirty-six to one revolution of main shaft. The third pinion, F2, mounted on a fourth shaft, C3, continuing in the same ratio of increase, has two hundred and sixteen revolutions to thirty-six revolutions of the third shaft, six of the second, and one of the main driving-shaft C; and so through any desired number of shafts, until the required velocity is attained, the ratio of increase of velocity of each succeeding shaft being as six to one ofthe shaft which drives it. A variation of the ratio of increase may be made by varying the relative number of teeth of drum A and the pinionsT; as, for example, if the number of teeth of the drum, as compared with the number et' teeth of the pinion, be as three to one, the ratio 'of increase will be four; if as four to one, the ratio of increase will be five.

Instead of the arms D Dl described, spur-wheels, sprocket-wheels, or pulleys may be used, and the transmitting-whecls maybe mounted upon fixed studs thereon. This may be done where it is desired to convey the motion of anT one or more of the shafts to the outside of the stationary drum A. H represents the spurwlieel to which the transmitting-wheels are applied, gearing with a corresponding spur-wheel, II', penetrating the casing through a slot formed therein, and mounted on a shaft outside of said drum or casing. The same result may be attained by sprocket-wheels or pulleys, and chains or beltis-an arrangement which will he found particularly valuable and useful in hoisting-apparatus, where, with the varying weight to be lifted, any one of a series of hoisting-ropes passing over the several pulleys thus arranged, the power may be applied with a varying speed and elfect. The partitions G may be simply diametrical arms or bars, affording a bearing for one end ofthe shaft to which it is applied, and may be secured between separate rings of teetlnas shown in fig. 3, in the end of one of the separate compartments Al A2 A3, 55e., of which the drum is formed, or inserted directly in the one main drum, A, and secured by screws passing through said drum from the outside, er in any suitable manner. The arms D may extend upon both sides of its shaft, and provided with a transmitting-wheel at each end, gearing with the drum and the same pinion in such manner as to balance and give additional strength to the structure.

What I claim as new, is-

l. The arrangement of two or 'more shafts in line with each other, one having a, pivotal bearing in and operated by the other, substantially as described.

2. The arrangement of the line-shafts within the concentric internally-coggcd drum or case, substantially as described. l

3. The internallycogged drum subdivided into separate compartments, or provided with the bearingpartitions for the line-shafts, as described.

4. The line-shafts provided with spur-wheels, or their equivalent, in combination with the internally-cogged drum, substantially as described.
