​​​​H. R.  Scientific Works

Metalic model with section cut of metal cylinder which is enclosed in a glass box, with working parts like piston, slide valve clearly visible so that link motion and reversing method can be observed. The movement of the wheel is light enough to demonstrate working even by blowing with mouth.

HERO'S ENGINE

Constructed of light and strong metal. section cut model showing air intake, axial flow, two stage, compressor, fuel supply, combustion chamber rotary turbine, thrust jet and exhaust, Printed diagram shows the working.

This model is made out of original parts, suitably sectioned and to demonstrate the working of Steering wheel worms, Steering arm, etc., The Arrangement of Wheels And Axle Connecting To steering system will be done so the movement of the wheels when rotating the steering wheels can be displayed . The model will be mounted on to a tubular frame, powder coated paint for  gloss and shine.  All the hardware's and gears will be suitably electroplated.

Operation of commercial steam engine fuel operated is well illustrated with this working model. The extra large size unit is provided with a horizontal boiler with a whistle, safety valve, on heavy aluminium metal base. 

Steam engine FUEL OPERATED (MEDIUM SIZE)


STEYRING MODEL

DIFFERENTIAL GEAR MODEL

Locomotive design, sectional, the valve and piston mechanism clearly visible through a glass plate with forward and reverse motions, demonstrates working with an air blower or even with mouth blowing.

Designed for comprehensive study of differential gear box components &  their operation. Automotive paints used for painting sectioned gear box assemblies. Handle to drive the bear box manualy.
The working cut section model designed to enable students to study different components of a Automotive Differential Gear Box & demonstrate its working. The setup uses an actual automobile differential gear box used in commercial vehicles, sectioned at suitable locations to display internal meshing gears. In order to visualize operation of the gear box , a handle is provided to rotate the gear box from input shaft. Optionally an electric motor can be provided to run the gear box.

Steam engine sectionaL

A functional model in metal. Comprises of a hollow bulb fixed at the center of a hollow shaft. Two arms bent at right angles at the end are fixed on to the shaft in opposite directions. The bulb along with this shaft rests on two stands at the two ends and rotates around it axis. Water introduced in the bulb is heated to boiling point to produce steam which comes out of the bent arms.
