To all 101mm it may conc rn:

Be it known that 1, Win-LIAM 1. McConmoon, a citizen .Qfthe United States, residing zit-Chicago, in the county .of flook and State of Illinois, have invented eel-"min new and useful Improvements in Power-Transmitting Devices, of which the iollowing is a My invention relates to variable speed gearing.

' One of the objects of my invention is .to provide speed changing gearing "in which a member may be driven at variable, seleeted speeds, from a substantially .constantrspeed drivin member vvithont unmeshing the gears members. I

In carrying my invention into effect 'I provide, preierably, a. sun-andl-planetsystern of gearing, comprising .a so called sun-gear, intermeshin with a plurality nf .epicylic planetary gears and arranged that the planetary gearsintermesh with endare contained within a surrounding, .fmternal-gear member.'

'In (the specific structure, herewith illustrated, the p1anetary,..or intermediate gears, are wbodily carried by the .driven'member, while the associate sun-gear .and internal gear may, selectively, be connected to .the driving member, or held stationary, in accordance with the relative speed and torque effect to be transmittedeto :the driven member. a

In .the embodiment shown in the accompanying drawings forming a, M 1; hereof, the invention is especially iwelliadapted for a counter-shaft for machine tools, such as 1athes,.shapers, milling machines, etc zwhere aplurality of speeds ahead .andas many in reverse direction are obtainable without the shifting .of "belts.

In the accompanying drawings.
