t. While there is some variation in the trains of clocks and watches, and in other particulars, they are generally named according to the form of their escapement; as, — Anchor-escapement.Detached escapement. Chronometer-escapement.Duplex-escapement. Crown-wheel escapement.Electric-clock escapement. Cylinder-escapement.Horizontal escapement. Dead-beat escapement.Lever-escapement. Recoil-escapement.Vertical escapement. Remontoire-escapement.(Which see.) Verge-escapement. Goodrich, in 1799, substituted a crank for an escapement in clocks, and received a bounty of £ 65 from the London Society of Arts. Its advantage was silence. A number of curious and ingenious escapements may be found in works on horology, in Denison's volume in Weale's series; Brown's Five hundred and seven mechanical movements ; and Piaget's The watch; its history and manufacture. Es-cape — valve. （Steam-engine.) a. A loaded valve fitted to the end of the cylinder for the escape of the

After selecting the width of the folder required, fold the goods where you want the first tuck; then introduce the folded edge under the folder and up against the gage. Stitch the first tuck and press it flat, then make a fold in the goods just wide enough to fill the whole space in the folder when the tuck just made is placed in the front edge or hook portion, which serves the purpose of a guide to keep the tuck just made parallel to the next tuck. Keep the space between the two gagelines full of cloth, and the tucks and spaces will be even. Tuck′ing-ga
