Advances in the Design of Refuse Collection Vehicles.
An Assessment of the Contribution made by Shelvoke & Drewry Ltd (1922-1991)
By BRIAN CARPENTER

Introduction
When Harry Shelvoke and James Drewry set up S&D to manufacture their unique design of small lorry, they thought of it as a general purpose vehicle. But very soon it gained popularity with municipal authorities for refuse collection, and this became the major use for the company's vehicles. Unlike many of their competitors S&D manufactured both the chassis and the body. In many cases the Freighter of 1922, which is often referred to as "The Tiller", replaced horse-drawn wagons for refuse collection.

Its advantages were:

1. Its simplicity of control. Two levers, or tillers, controlled the vehicle situated to the right and left of the driver. One controlled the steering, the other the epicyclic gear box, which eliminated the need of a clutch pedal. The driver also had an accelerator and a brake pedal.

2. The diminutive 20 inch diameter solid rubber tyred wheels permitted a low loading height, and eliminated punctures from landfill sites.

3. Hydraulic tipping was provided, where most competitors relied on manual means of tipping the body.

4. Automatic lubrication was provided to all moving parts, eliminating the need for regular greasing.

5. Canvas or steel shutters were fitted, to lessen the amount of dust discharged into the atmosphere from the previous open lorries.

In practice the vehicles were found to be more economical than the use of horse-drawn vehicles.
