IMPROVEMENT III MECHANICAL MOVEMENT.

To ALL `WHOM 1T MAY ooNCnnN;

Bc it. known that we, ARTHUR W. Bnownn, of Brooklyn, and WILLIAM F. GOODWIN, of East `New York, both in the countyof Kings, and State of New York, have invented a new and useful Improvement in Mechanical Movements, for multiplying and transmitting motion or power; and we do hereby declare the following to bea full, clear, and exact description ofv the same, reference being hadtothe accompanying drawings, which' are made a part of this-specification.. l p Y' v l Figure 1 represents a transverse section at :c x, iig. 2, of a movement illustrating our invention.

Figure 2 is a sectional elevation of the same, at y y, iig. 1.

We employ a shaft, which may or may not be a `driving-shaft, having keyed to it a series of cog-wheels, and running loosely upon it, between the'said cog-wheels, a series oflpinions, carrying arms, on the extremities of which are a pair of geared pinions, one of which mesheswith the driving-cog wheel, around which vthey irre carried by the arm, while thc other is cast, or rigidly and concentrically attached toa'cog-wheel of larger diameter than itself, which gears with the next loose pinion on the shaft, as will be hereinafter explained.

In the drawingsy A may represent a driving-wheel or pulley, of any suitable construction, which may be rotatedbyany power. C may represent a driving-shaft, mounted in bearings, of which one, B, is shown, and rotated by wheel or pulley A. D D1 D2 represent cog-wheels, keyed to the shaft C, so as to berotated-therewith. E E1 E2 are pinions, running loosely on theV shaft C, betweenI the cog-wheels D D1 D2. The pinons E El each carrjT an arm, F1 F3. Mounted on stud-shafts are a pair of geared pinions, G H, one of which, G, meshes with the cog-wheel'D, and communicates to the pinion H rotation in the samefdirection as that of the wheel D. Attached rigidly and concentrically to the pinion H is a cog-wheel, I, which gears with the looseA pinion E, on the main shaft, rotates'it around Lthe shaft in an opposite'directiom Mounted upon the outer end of the arm F are a second pail` of geared pinions Grl H, similar to the pinions G- H, the pinionG1 gearing with the cogwheel D, and the pinion H1 carrying a concentric gearwhecl, Il, ot' larger size, which is thus rotated in y the same direction as the shaft C, and meshes with the second loose pinion El, while all the wheels, G1 I-Il Il, are, by the arm Fl, carried inda'n orbit around the shaft C, in a direction opposite to the rotation ofthe latter.`

It will thus appear thatth'c orbital revolution of the wheel I around the shaft, communicates rotation to it through the wheels DI, G1, and-H1, at a high speed, which is further increased by the rotation of the wheel` D, in the opposite direction, and the axial rotation and or-bitairevolution of the wheel Il combine to impart a very rapid'rotationito the loose4 pinion El, which, carrying the arm F2, on\the extremity of which is mounted a third train of \\|'hecls,-Gr2v H2 I2, drives the third loose pinion E2 at a still multiplied speed, and this multiplication may he continued in the sameway to any extent desired, by adding other revolving arms, `with their accessory trains of gearing, and the motion ofthe last pinion in theseries being communicated toapulley,` to drive a belt, a crank-wrist to work a pitman, or to any instrument to which it is desircdto'impart a rapid motion, whether reciprocating or rota-ry.- I

It', on the other hand, it is desired to multiplypowcr, the power may be appliedfthrough'a crank or pulley, or otherwise, to the last pinion of the series, (represented by E2 in the presentilluistratiom) and the eii'ect will be to communicate rotation to the wheel or drum A at a low speed with very greatpower.

By making each of thc revolving arms Fl F2, Src., u. part of adrum, which may enclose the respective trains of gearing, as illustrated by red outline in fig. 2, we propose to provide a set or succession o f pulleys or wheels, whichmay rotate at different speeds upon the same shaft. Beltsv or gearing may convey this motion, at whatever speed dsired, to thc place where it ispto be used, or a single belt, by being shifted from one such pulley to another, may be employed to drive machinerylat variable speeds.

We have thus for described our invention-with the shaft C as a driving-shaft. It will be'lmanifest that if the said shaft, with its wheels D Dl D2, be stationary, and the sleeve B be driven around it, which may `be eected by mounting the wheel A on the said sleeve, instead of keeping it on to the shaft itself, the arm F, on which lthe wheels G H I are mounted, will carry them around the shaft in the same way as the arms Fl F2, with their trains of wheels,andl the eleet will be the same.

Thearrangement last' named is good for hoisting purposes, and by applying the power to either of the 'different pulleys, indicated by red lines, the hoisting-drum muy be. rotated with greater speed or power, as

circumstances require. v A

A keyfseat may be eut throughout the length of theshaft C, so that any number of sections f gearing can be secured thereon, or any of them removed at will.` v ,x

' We dounot herein claim anything Vdescribed in William F. Goodwins'patent of December 31, 1867.4 Our present invention vconsists in a dierent means for aecomplishing the same result, the dilerencc being in the use of the fixed'whels instead of the internal gear.

HaringthusV described our invention, 'the following is what we claim as new therein, and desire to secure 1..We claimany number ofsrovolving arms F I"l F2, caehcarrying n. train of wheels, rotated by the wheels D D D2, in the manner herein described, to communicate motion with multiplied speed or power.

Y 2. Werelaim the intermediate pinions G Grl G2, employed in combination with the wheels D H I, substantially as and, for the purposes explained. l
