| Show improvement IN SHAFT MOTION an improved anine engine connection for transmitting motion to shafts shaft s has been invented by mr T doyle of new york the arran arrad arrangement ement of two beam engines in line with each 2 other that is to say with their beams in the same plane and with the cylinder ends of the engines contiguous to each other and connect connecting ln their piston rods or beams by an intermediate beam by tilis tills means the two shafts which are parallel with and at some distance from each other are caused to rotate at a uniform speed the main objector object of the invention is its application to drive two pairs of paddle wheels to propel a vessel but it ivay also be used f for or driving two parallel shaf shafts Is f for or other purposes by this of connecting the engines the tho cranks of two shafts are always kept in opposite pa positions and when one ona piston is descending the other i is s always ascending this tills mode is said sald to form a simple and effective arrangement for driving tw two shaf shafts Is to it causes the power to be transmitted equally if the resistance be equal or always in proportion to tile the relative amount of resistance |
