Serial No. 661,293 . (No model . )To whom it may concern Azz . -Know that , ROBERT HUGH - sythe FINLAY , soap and candle maker and HENRY ARGHIBALD FINLAY , electrical engineer, Victoria Square , in the city of Belfast , County Antrim , Ireland, have invented certain new and useful improvements in Transformationof speed gears , and we hereby declare that the following is a full, clear and accurate of the invention , in a way that others skilled in the art to which it belongs to make and use the same , the reference is had to the accompanying drawing , and letters of reference marked thereon , which form a part of this specification .Our invention relates to transmission power of a rotating shaft to another which is desired to drive at a different speed in the same or the opposite direction.To carry out our invention employing gearing systems substantially as described hereinafter and as illustrated in the accompanying drawing , wherein the figure is a longitudinal section of a gear system for carrying out our invention in eifect .Referring to the drawing , a is the high-speed shaft carrying the pinion bb . Freely mounted on a shaft outside the sprocket 19 b are two disks 9 g , which is supported by a plurality of axes of f , uniformly spaced . After each shaft is mounted a series of gears d, e , c, d , cl gears 01 and meshing with the pinions and 1 b ), respectively. Gears d , e, c , and d on each axis must be connected to move together , and this can be done by typing the f axis and assembly of the last turn in their audiences , or those gears - can be placed or secured in some way to each other and rotate around the axis - . The low speed shaft is indicated by 7c, and disc Z is rigidly connected to the axis and carries an internally toothed ring h , with which all the gears 01 mesh. Z other disk is provided with a sleeve 7e rotatably mounted on the shaft 70 , and this disk has a ring internallytoothed h , with the gears all mesh mail . Z other disk is provided with a sleeve is , in turn mounted on the sleeve and this disc bears h internally toothed ring , with which all the gears mesh c . tothe shafts and sleeves 7c and 7c ' , respectively , are secured the pulleys c' , i , t ' .Note that the rings h , h, h are of different diameters , the ring 72 . being the smallest and the ring h , the largest, and also the gears ( Z , E , and C also are of different diameters , 61 being the smallest and the largest c . pinion b dy The gears are provided for give strength and stability to the gear system .However, if the shaft is rotated one byb pinions rotate in the same direction , but the gears d , e, and 0 is rotated in the opposite direction , its axis is supposed to is stationary, and if the rings h , h and h ' are free to move and that the pulleys c' , i , i and all move in the same direction as the gear is, in a direction opposite the axis - = but the speed of all the pulleys greatly reduced shaft speed but not to the same extent . pulley 2 ' run slower, the pulley 2 " side , and the pulley i" the fastest of the three.Whether the brake of the pulleyi be tightened enough to hold the ring and against ro h - station 1 , then the gears 01 will travel within the fixed ring h in the same direction as the shaft (1 moves and impart same movement gear ey C , disks g and f axes . eyc gear peripheries are , however , travel faster than the gear d and thus still exerting pressure on the rings to hyh move in a direction opposite to the movement of the shaft , but at a much slower rate than when all the rings are free to rotate .If 2 applies a brake to the pulley c " , the i pulley and cause the ring to be moving in the same direction as the axis , while the pulley c ' and ring h still move in the opposite direction di - ' direction , but further reduced speed , and if a brake 2 is applied to the pulley 71 , both pulleys 2' and 2 " will move in the same direction as an axis , but at different speeds.We illustrate three pulleys and three ring gears meshing with three gears , pulleys being arranged in close proximity on the same side of the machine. It is , however obvious that the pulleys can be widely separated from each other by simply lengthening the sleeves, and also that one or more of the pulleys may be mounted on the opposite side of the machine and the number of pulleys , gears - rings, and gears can be increased and still be within the scope of our regard, one or more shafts supported for rotation about the high speed shaft , the gears of different diameters made by said axle and revoluble mobile together different diameters internallytoothed rings meshing with said gears , and one of said gears meshing with the pinion on the high speed shaft , the pulleys connected rigidly to the respective rings , and the means for holding any one of sheaves against rotation , substantially as disclosed .
In witness whereof we subscribe in the presence of two witnesses.ROBERT HUGH FORSY'llIE Finlay. HENRY ARCHIBALD Finlay. \ Vitnesses :I'IYNDMAN HUGH , HUGH Roddy .
