APRON MECHANISM IN LATHE

APRON MECHANISM IN LATHE Apron Mechanism: Apron is attached to the carriage and hangs over the front side of the lathe bed. It is useful in providing power and hand feed to both carriage and cross-slide. It is also used to provide power feed to the carriage during thread cutting through two half nuts. The construction of apron is shown in Fig. Fig - Apron Mechanism Construction Power is transmitted from the spindle to the lead screw and feed rod through the spindle gear and tumbler gear arrangement. A worm is mounted on the feed rod by a sliding key. The worm meshes with a worm gear on whose axis another gear G1 is attached. Gear G1 is attached to a small gear G2 by a bracket as shown in the diagram. Gear G4 is positioned to be in mesh with the rack gear always. Another gear G3 is mounted on the same axis of gear G4. The carriage hand wheel meant for longitudinal feed is attached to the gear G5 on the same axis. The gears G3 and G5 are always in mesh. The gear G...

Boiler Mounting - Water Level Indicator

WATER LEVEL INDICATOR Function: It is indicates the water level inside the boiler to an observer. Working: The water of the boiler comes into the glass tube through the lower tube and the steam through the upper tube. The water then stands in the glass tube at the same level as in the boiler. Two cocks are used to control the passage of between the boiler and the glass tube while the third cock is in used to discharge some of the water from inside the boiler to see whether the gauge is in proper order or not. The glass tube is protected by means of a cover, made of specially toughened glass, which will prevent any accident that may happen due to breaking of glass tube. It is used for ordinary boilers.
