Cast-Iron Grating

Where required, typically in larger structures or where aesthetics were important, heating pipes were frequently laid in trenches below ground level, sometimes along a pathway. To allow air to circulate, heat to escape, hide unsightly pipes and provide, where necessary, a sound walking surface, cast-iron grating was normally used to cover the trench. From a heating perspective, this was a sub-optimal solution as it has been estimated that the effectiveness of underground pipes could be as low as 50 per cent when compared with their above ground equivalent. In addition, the initial installation costs were higher because of the additional excavations and cost of the iron grating.

Patterns

In the first three decades of the twentieth century the firm were offering 26 different patterns, ranging from the purely functional through to the very ornate. Most were available in varying widths, lengths or thicknesses and a few could be provided in any size to order.

Kerbs

In order to support the grating iron kerbs were often used. These were fixed typically placed on brick supports and carried the iron grates. This allowed the grates to be lifted and removed when access was required the heating pipes.

Pattern No. 1

This was a strong grate, typically used in vineries.

 

No. 1 Pattern

In the early 1890s the firm was offering the borderless option (8in. wide, 3ft. 6in. long and ¾in. thick) together with three bordered width variants: 2ft. 4in., 1ft. 6in. and 1ft. 4½in. – all 3ft. 6in. long and ¾in. thick.

By 1897 three different size border variants were available:

  1. 2ft. 4in. wide; 3ft. 5¾in. long; ¾in. thick.
  2. 1ft. 6in. wide; 3ft. 5in. long; ⅝in. thick.
  3. 1ft. 4in. wide; 3ft. 5½in. long; ⅝in. thick.

The borderless variant was also available, although slightly smaller measuring 7¾in. wide, 3ft. 5in. long and ¾ in. thick.

 

In both 1913 and 1915, the firm had added an additional size variant, although the borderless offering was not available:

  1. 2ft. wide; 3ft. 5¼in. long; ¾in. thick.

By 1925 the borderless variant had returned; the same size as in 1897.

In 1937 and 1938 an additional variant had been added to the list – a heavy pattern grating with small mesh measuring 2ft. 4in. wide, 3ft. 5¾in. long and ¾in. thick. The borderless option was still available in the same size as 1897.

Pattern No. 2

A strong grate, suitable for narrow walks, it had been discontinued by 1913.

 

No. 2 Pattern

In the early 1890s it was available in two size variants:

  1. 1ft. 4½in. wide; 3ft. 6in. long; ⅝in. thick.
  2. 1ft. 2½in. wide; 3ft. 6in. long; ⅝in. thick.

In 1897 it was still available in two sizes, although fractionally thicker and shorter:

  1. 1ft. 4½in. wide; 3ft. 4in. long; 9/16in. thick.
  2. 1ft. 2½in. wide; 3ft. 5½in. long; 9/16in. thick.

Pattern No. 3

No. 3 Pattern
  1. 1ft. 10in. wide; 3ft. 10in. long; 9/16in. thick.
  2. 1ft. 1½in. wide; 3ft. 6in. long; 9/16in. thick.

It was still available in two sizes in 1897, although one was fractionally narrower and the other fractionally longer.

  1. 1ft. 9¾in. wide; 3ft. 10in. long; 9/16in. thick.
  2. 1ft. 1½in. wide; 3ft. 5½in. long; 9/16in. thick.

In 1913, 1915, 1925 and 1938 it was still available two size variants, again the sizes had changed very slightly:

  1. 1ft. 9½in. wide; 3ft. 8in. long; 9/16in. thick.
  2. 1ft. 1½in. wide; 3ft. 5⅜in. long; 9/16in. thick.

  1. 1ft. 2in. wide; 3ft. 4in. long; ½in. thick.
  2. 8in. wide; 3ft. 4in. long; ½in. thick

In 1897 it was offered in two size variants, one slight shorter and the other slightly longer:

  1. 1ft. 2in. wide; 3ft. 3½in. long; ½in. thick.
  2. 8in. wide; 3ft. 5½in. long; ½in. thick.

 

 

Pattern No. 5

A light grate.

 

No. 5 Pattern

In 1897, whilst very similar to the pattern available later, it appears to have slightly different border, although this could simply be due to a poor drawing: at the time it was offered in two size variants:

  1. 1ft. 5in. wide; 2ft. 6¾in. long; ⅝in. thick.
  2. 1ft. 3½in. wide; 2ft. 7in. long; ⅝in. thick.

Pattern No. 19

This was similar to Pattern No. 1 without the border and in 1897 only available in one size measuring 11½in., 3ft. 5in. long and ⅝in. thick.

However, by 1925 this had been reduced to nine with the removal of the 7¾in. wide, 3ft. 5in. long and ¾in. thick variant.

By 1938 this range had been reduced further with the removal of 2ft. 2½in. wide size.

 

 

Pattern No. 20

In 1897 it was available in a single size, measuring 1ft. 4½in. wide; 3ft. 10¼in. long; ½in. thick.

 

No. 20 Pattern

By 1913 this single size had altered slightly measuring 1ft. 4¾in. wide, 3ft. 9⅜in. long and 9/16in. thick.

  4. 2ft. 5¾in. wide; 3ft. 7½in. long; ¾in. thick.

These four sizes were still available in 1938.

No. 21 Pattern

In 1913, the thickness had been increased to 9/16in., although this had been reduced to back to ¾in. by 1915 where it remained until after 1938.

Pattern No. 22

Introduced prior to 1913, this was a solid chequer plate rather than a grate and often used at entrances.

It was initially available in three size variants: 12in., 14in. and 15in. wide, 1ft. 10¼in. and 2ft. 6in. long and either ⅜ or ¾in. thick.

 

No. 22 Pattern

In 1915, the firm offered five size variants ranging from 6½ in. to 15in. in width, 1ft. 10¾in. to 4ft. in length and in four thicknesses from ⅜in. to ¾in. in ⅛in. intervals.

By 1925 the number of sizes had increased to fourteen. Widths varied from 5½in. to 20in.; lengths varied from 1ft. 10¼in. to 4ft.; there were three thicknesses, ½in., ⅜in. and 7/16in.

The same 14 sizes were available in 1937 and 1938.

From its introduction the firm could, to order, provide any size the customer required.

Pattern No. 23

In 1897 pattern No. 23 was a circular grate, measuring 2ft. 11in. in diameter and ¾in. thick.

 

No. 23 Pattern available in 1897

By 1913 the circular grate had been dropped to be replaced by an extra heavy, non-slip variant of pattern No. 9.

 

No. 23 Pattern introduced prior to 1913

Whilst it was offered seven size variants, similar to pattern No. 22, it was available to order in any size. As standard, it came in three thicknesses – ½in., ¾in., and 1in. and seven widths from 6in. upto 23¼in. It was still available in these size variants in 1938.

 

 

Pattern No. 24

Available by 1915, there were six size variants on offer ranging from 8¾in. to 19½in. in width, 18½in. to 36in. in length and ¾in. or 1in. thick, although any size could be made to order.

 

No. 24 Pattern

By 1925 this had increased to nineteen size variants, ranging in width from 8¾in. to 37in.; in length from 15in. to 60in.; in five thicknesses from ¾in. to 1⅜in.
