In the nomenclature of the mechanic arts, the names of animals have not been entirely overlooked e. g.: — Ass.Cricket.Hound.Rat. Bear.Crow.Jack.Seal. Bee.Dog.Jenny.Serpent. Beetle.Dolphin.Kite.Skate. Buck.Drill.Leech.Slug. Buffalo.Fish.Lizard.Snail. Bull-dog.Fly.Mole.Sole. Butterfly.Fox.Monkey.Starling. Camel.Frog.Mouse.Swift. Cat.Goose.Mule.Throstle. Cock.Hawk.Pig.Turtle. Cow.Hedgehog.Pike.Urchin. Crab.Hog.Ram.Worm. Crane.Horse. Each of these useful animals is described in its alphabetical place. Ani-mal trap. A device for catching animals. There are numerous varieties; some to set in the path of the animals, others are pulled off by a person on watch; the more common forms are those in which the animal is the cause of his own capture by meddling with the b

in each scale, or with 1/9000000 part of the weight. Coin balance To the mode of suspending the beam and the scales more attention has probably been directed than to any other part of the balance. Of some of the European balances, — Fox's beam has pivots, the conical ends of which play in hollow agate cones of larger angle. Oertling's beam is coated with platinum or palladium, the knife-edges and planes being of agate, and the instrument proof against acid fumes. The knife-edscending till the ends of the brushes touch the under side of the pan. The mode of obtaining quiescence of the pan in the periodical intermittence of the coin-weighing apparatus is by a depressed ivory point above and an agate point beneath. In Fox's balance the beam is brought to zero by the attraction of a magnet. The sensitiveness of a balance depends (after friction has been reduced to a minimum), first, on the proximity of the center of gravity to the point of suspension on which the

est motion. These strips are then covered with cotton or silk, and woven in an endless web. See caoutchouc. E-las′tic-fab′ric loom. One having mechanical devices for stretching the rubber threads or shirrs, and holding them at a positive tension while the fabric is woven. E-las′tic goods. Those having elastic cords, called shirrs, inserted in a fabric or between two thicknesses. E-las′tic mold. Elastic molds of glue for taking casts of undercut objects were invented by Douglas Fox, Derby, England. The body to be molded is oiled and secured about an inch above the surface of a board, and is then surrounded by a wall of clay rather higher than itself, and about an inch distant from its periphery. Into this, warm melted glue, just fluid enough to run, is poured, completely enveloping the object. When cold, the clay wall is removed, and the mold delivered by cutting it into as many pieces as are required, either with a sharp knife or by threads previously placed

on of many works which could hardly otherwise have been attempted. In its invention we find credits to Clements of London, who was a workman in Bramah's shop; to Fox of Derby, and to Roberts and Rennie of Manchester. Bramah, it appears, employed, in 1811, the revolving cutter to plane iron, thus adapting to metal the form foundls cut both ways. Much of the moved on rollers, and the tools cut both ways. Much of the work for Babbage's calculating-machine was planed on Clement's machines. Fox made a planing-machine, in 1821, to plane the cast and wrought iron bars used in lace-machines. It planed 10 feet 6 inches, 22 inches in width, on an object not abces of the mold; more plaster is then poured on, which, in setting, evolves sufficient heat to render the wax pliable and allow it to be removed from the cast. Mr. Fox's method of forming an elastic mold in two pieces capable of delivering undercut surfaces is, after oiling the body to be molded, to cover it completely with a th

A ball on one shaft enters a socket on the end of the other, and is held there by a key passing through a slot in the ball and retained in place by a cap, allowing a certain degree of rolling motion. k.

The end of one shaft has a screw-threaded tenon of peculiar shape, which enters a correspondingly threaded cavity in the enlarged
