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. 511. STEAM SOUNDING MACHINE. Sigsbee type. Its prin-cipal parts are the drum, A, on which is wound the wire, the auxiliary pulley, B, used while heaving into relieve drum of the strain, thejockey wheel, C, the swivel pulley,D, the accumulator contained inthe tube, H, and the brake E. The drum is made light, inorder to have as little inertia andmomentum to overcome as pos-sible. Its circumference is onefathom. An indicator is attachedto the axle, which registers thenumber of revolutions. The auxil-iary pulley, B, is composed ofthree pulleys : one for the wire,one for the belt going to the drum,and the other for the belt from thedriving engine. The jockey wheel,C, is an ordinary gun metal onewire passes over this both inpaying out and reeling in. Its circumference is 3 feet, and an odometer. with a V-shaped score, and the 202 NAVIGATION, VESSELS, MARINE APPLIANCES, ETC. being attached to its axle, the amount of wire paid out can thus beobtained. A very important feature in this machine is the accumu-lator, which is composed of spiral springs contained in two verticaltubes, one of which is shown at H. These springs are connected withthe crosshead of the jockey wheel by means of chains passing over thepulley K. The crosshead moves in steel slides, and rises and falls asthe weight on the wire varies, indicating on a scale the strain in pounds. 512. THE DRAG STEERING GEAR. Different rigs for con-structing and operating a temporary steering gear when the rudder is disabled. The float isa strong plank, so fast-ened bythe rope harnessas to keep it in a verti-cal position in the sea. 513. Tackle rig froma projecting spar andcross tree. 514. Rope hitc
