CAM Apparatus Analysis
The apparatus is designed to study the cam profile and Performance of Cam and Followers system. It consists of a shaft supported in ball bearing and driven by variable speed D.C. Motor. Various types of Cam can be mounted on this shaft. A push rod Assembly is supported vertically and various types of flowers can be attached to be pushrod. A dial gauge is provided to plot the follower’s displacement with respect to rotation of Cam. Provision is also made to vary the weight or spring compression on follower assembly so that effect of follower eight or spring force on jump can be studied. With the help of stroboscope (Not include in cope of supply)

Worm & Worm Wheel Working Model
Model of Lanchashire Boiler Steel shell is about 75 cm. Long and 22 cm in diameter. Two large tubes known as fire tubes pass from end to end. At the front end of each tube a furnace fire grating is placed and a door is hinged. Brick work, seating and flues are shown in wood work. The boiler is complete with dead weight safety valve, manhole, mudhole, check valve high steam and low water safety valve, steam and water gauges, regulating draught doors, dampers with counter weights and chimney. The model is approximately one meterin length,37 cm. In breadth and 45 cm. High. It is specially made dissectible for demonstration purpose.
Model of Locomotive Boiler
The model is specially designed to understand the working of a locomotive steam boiler. The steel shell is of about 20 cm. Dia and 60 cm in length. The fire box is provided with a door and gate. The dissected barrel shows its inside view. Hot gases after passing through the fire tubes enter the smoke box with a door, nozzle and the blast pope. The model is approximately 100 cm in length, 45 cm high and 35 cm in breadth and is complete with whistle, steam dome, safety valve, check valve, steam regulator water and steam gauges.
Model of Chochran Boiler
This is the best known vertical type fire tube boiler. The shell is about 25 cm in diameter and 60 cm high. The cylindrical fire box is with a door and gate at its bottom. Hot gases pass from the fuel to the combustion chamber through a short flue pope and then to chimney through the tubes. At both ends of the tubes, covers are given and tubes can be cleaned after their removal. The model is complete with feed check valve, steam and water gauges, stop valve, safety valve and manhole.
