. Mechanical appliances, mechanical movements and novelties of construction; a complete work and a continuation, as a second volume, of the author's book entitled "Mechanical movements, powers and devices" ... including an explanatory chapter on the leading conceptions of perpetual motion existing during the past three centuries. 927. PERPETUAL MOTION. Revolving tubes and balls. Theballs, A and B, are in equilibrium because they are at an equal distance from the vertical line that passes throughthe center E. By the construction of themachine, the ball, D, being, on the con-trary, more distant from the point of sup-port than the ball, C, must prevail over thelatter and break the equilibrium. It mustthen descend to the point, B, and causethe apparatus to make a quarter revolu-tion. Now the latter can not take placewithout the rod, A, B, which was situatedvertically, assuming a horizontal position, and then the balls, A and B,are to each other as were the balls D, C. One must overcome theother and cause the apparatus to make another quarter second quarter revolution can not take place without being fol-lowed by a third, through the new position assumed by the balls A, B,Specious argument oj the PERPETUAL MOTION. 371 928. PERPETUAL MOTION. Geared motive power, a is theaxis or shaft on which the wheels are all mounted ; each wheel consists of two parallel rims, h, b, eachof which is connected by radialarms, c, to a boss, d, keyed onthe axis, a; the working partsof each wheel are mounted be-t w e e n the rims and arms^J thereof, but the outer rim,boss, and radial arms are re-moved in the figure in orderthat the working may be fullyshown. It must be understoodthat the pivots or axis, /, j, n, t,hereinafter referred to, on whichcertain parts are mounted, aresupported by and extend between the two parallel rims, radial arms,and bosses of the wheel, b, c, d. e, e are curved arms working on axes orpivots, /, fixed in the rims; each arm carries weight
