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. laid in an ellipse on an inclined framework extending from near the topof the central framework to the level of the roadway of the cables connect the counterbalance weights with the free end of thedraw, the cable passing once around the pulleys at the top of the frame-work. The pulleys are mounted upon a 3-inch shaft which extends ENGINEERING AND CONSTRUCTION, ETC. 333 along the top of the central cross beam, and which is provided at its right-hand extremity with a pinion 2§ feet in diameter. This engages witha small pinion that is mounted on the shaft that is rotated by the endlesschain from below. The draw is almost balanced by the weight of therollers. 86i.
