TO ALL WHOM IT MAY CON CERN 4 Beit known that I, ARTHUR W. BROWNE, of the city of Brooklyn, in the county of Kings, and State of New York, have invented `a. new and useful Mechanical Movement for Converting Speed into Power, to be employed for hoisting, drawing, and driving purposes, and fo'r all purposes when such movement, apparatus, and power are required undl can beappliedj and I declare the following to be a full and exact description of the same, re`er` ence being had to the accompanying drawings, which form a part of this specification, and in which- Figure 1 represents -a sideviewof a hoisting-machine embodying my invention, showing the relative positions ofseveral parts of the apparatuswhen -put'together and ready for use, the positions of the cams C being indicated by dotted lines. l I

Figure 2 is a sectional view'of parts of the same apparatus, the section being cut through the centresof I the plate A1, cams C C, and shafts S and Sl Si, showing the manner in which the several parts are attached to each other.

igure 3 is a detached view of the' toothed plate or disk Al andsections through the cams C C and shafts Sl Sl and S, also showing the enlarged hole in the centre of the plate through which passes the shaft S.

Figure 4 is a detached sectional View4 of the shaft SL, cam C, and gear-wheel B. The section being through the centre of the pieces-shows the manner in whichA the'samc are put together.

Figure 5 represeuts a side view of a machine embodying the same principles of my invention, in which the external ilangedplato A2 is the driving-plate in which thcinternal wheel A? is made to revolve. The positions of the crank B2 andcam C1 are indicated by dotted lines. I

Figure 6 is a. section through the same machine shown in fig. 5, showing the manner of its construction.

Similar letters indicate corresponding parts inthe several figures. t

My invention consistsin a new mechanical movement, the mechanical arrangement of the apparatus vo. which makes asimple and powerful machine for convertingspeed into power, which machine can be applied for hoisting, drawing, and 'driving-purposes, and for all other pur-poses where such movement and machine can be y applied and used. I will-now proceed to describe the construction and operation of my invention,.refcrring tothe accompanying drawings.

Letter A represents a. hanged wheel, the flange of which projects on one side, and forms a recess, in which the plate Al is secured and operated. The inner surface of the flange on vthe wheel A is provided 'with teeth or A cogs, which mesh or gear with the corresponding teeth or cogs on the outer surface or periphery'of theplate A, making an internal gear. l

Letter Al is a disk or plate having teeth or cogs on the outer surface or periphery made to correspond and mesh with the internal cogs of 'the wheel A, and having holes arranged on a line drawn through thevcentre of plate, oneon each side of the centre, into which the vcams C C are fitted, and one in the centre, through which the main shaft S passes. v

Letters B are gear-wheels on the outer ends of the short shafts Sl Sl, which, being drivenby the gearwheel Bl onthe shaft-S, serves to impart motion through the-shafts Sl Sl and. cams C C to the 4plate A.

Letter F is journal-boxes on the frame which serve as bearings for the shafts.

Letter D is a drum attached'to 'the revolving wheel A, on which a rope or chain may be used.-

Letters P and Iarc pins and ribs shown in Egs. 5 and 6, which serve to hold the external anged gearA plate from turning. l

Letterl's the driving-plate anclA3 the revolving wheel. The same principle may be applied byplacing the cams or .cam C in the external plate A2, and thus changing it to the driving-power and attaching the drum or shaft to the wheel A3, which arrangement causes the internal instead of the external wheel to revolve, as seen in figs. 5 and 6.

Having thus described and shown 'by drawings the manner of constructing my machine, I'wll proceed to describe its operation, referring to the drawings.

The shaft S, having its journal-bearings in the b oxes Fon the frame, forms the .pivot and means of support for the revolving wheel and drum, and having one end projecting out throughv the hoi: F on `the outside of the frame, forms a receptacle and means of support forthe wheel Bl, to. which the cranl': or driving-pulley is attached. Thewheel B1 being mounted on and having its journal-bearings o n theprojecting end of l.the shaft S, rotates around and to the reverse of the shaft. The wheelsvB B being in gear with the .wheel Bl, are rotated by the same, and being mounted on the outer-ends of the short shafts Sl Sl, on t'heinnerv ends of which aire mounted the cams C C, serve to rotate the cams, revolviug'themin the same direction with the wheels B B. The cams C C being fitted into corresponding holes in the plate A.as seen in figs. 1, 2, 'and 3serve 'to operate the plate Af, theV revolving of the cams giving lto the driving-plate an eccentric movement, causing it to move about in the cirelel of and in gear with the wheel A, and by means of'the two cams', varranged one on each side of the centre, the plete is held from turning, and a uniformmovement to both the driving-plate and revolving wheel is obtained.

The external revolving wheel A, as arranged in figs. 1 and '2, has'seventy-two teeth or cogs, and the plate A1 has seventy corresponding teeth or eogs, which mesh with the cogs in the wheel'A, the dierenee in the number of teeth beingtwo, and the diiference in the diameters of thevwheel A and plate Al being precisely the same as the throw of the eams'C, which cams are so arranged on -the shafts S Shoud in the plate A1, and in relation to the circle of the wheel A, that the plate A. is always held in gear with the wheel'A on the side towards which the cams project, and at the same timedrawn out-of gear on the opposite side from which the cams are thrown. The plateAl is supported and operated 4by the cams C C. The rotating of the cams causes the plate `Al tomove about in'the wheel A, The plate A1 having a less number of teeth, and being smaller in diameter .than the wheel A, draws-out ofand enters into gear with the wheel A, causing it to move around, One revolution yof the cams C C moves the plate'A1 vabout in the wheel A one time,- gainng the difference in the number of teeth, which in this case is two, as shown in gs.'1 and 2, moving the wheel A and drum D the distance or space of two teeth for every'revolutioniof the eams. IThus when the number of teeth is'seventy-two in the wheel A and seventy on the plate Al, thirty-ve revolutions of the cams are required to produce one revolution of the' wheel A5101, if one tooth should be added tothe plate A1, making the difl'erenceof but one tooth, thenthe number of revolutions-of the cams would be doubled, requiring seventy revolutions of thecarus 'to produce one revolution ofthe wheel A; or ifV the differ-ence in the number of teeth were three, then twenty-three revolutions of. the cams would be required te produce one revolution of the whcelA. If the difference in the number of teeth contained in the wheel and plateis but one, the eam's'have but little'thro\v,only suiicient to hold the plate in `gear on one side and disengageit from the other, which movement causes the 'plate' to gain the one tooth, by which means great power is obtained, v l

- The drivingplate being mounted on andbperated bythe cams, docs not revolve or roll into gear like a Jmmon gear-wheel, but, having an eccentrieqnovement imparted te it by the rotating ot' the cams, whichl tauses its teeth to slide into gear with the teeth of the revolving wheel on one side, while the same movement disengages them from the other, this movement continues all around the revolving wheel, heaving or pushing it around, thus revolving the wheel and drum or shaft or otheappliances attached to it.

Having .thus desribed myA invention, what I claim as new, and desire to secure by Letters Patent, is

1. The wheel A, plate A, shafts S S', and cams C C, or their equivalent, arranged to operate together in' the manner and `for the purpose substantially asvdescribed.

' 2. The plate A, wheel A3, pins P P P P, and ribs I I, arranged to operate together in the manner and for the purp'ose4 substantially as'described.
