"The drum armature differs from the shuttle armature chiefly in that it employs many coils instead of one. The cylindrical iron core is made of thin disks of soft iron in insulated from each other, thus minimizing the 'local currents' and the heating effects thereof." — Avery, 1895

"The chain-pump consists of a tube or cylinder, the lower part of which is immersed in a well or reservoir, and the upper part enters the bottom of a cistern into which the water is to be raised. A chain is carried round a wheel at the top, and is furnished at equal distances with movable bottoms, which fit water-tight in the tube. As the wheel revolves, they successively enter the tube, and carry the water up before them, which is discharged into the cistern at the top of the tube." — Wells, 1857

"This machine consists essentially of a horizontal piston and cylinder engine fixed upon a platform carried upon four wheels, which are coupled together by side rods, so that on motion being communicated by means of a mitre wheel in the hind axle, it can be moved forward by hand. On the forward end of the frame are two bosses forming the centres for a pair of bell cranks or bent levers places close to the ground, and facing in opposite directions, either one of which can be connected with the piston rod. The outer arm of each lever carries a square socket, into which is fixed the pick, which has two cutting heads, one placed a little in front of the other so as to cut to the whole depth at one operation." — Encyclopedia Britanica, 1893
