Portsmouth Block Mills

Brunel presents the Admiralty with his proposal to mechanise the production of ships' pulley blocks for the Royal Navy.

Brunel works with Henry Maudslay to produce models and machinery for the manufacture of ships' pulley blocks.

Brunel obtains a patent covering machinery for manufacturing ships' pulley blocks.

Brunel develops a linked sequence of specialised machines so pulley blocks can be produced repeatedly to standard dimensions.

Brunel proposed a system for manufacturing rigging blocks using specialised machine tools. The installation demonstrates the adaptation of existing dock infrastructure.

Samuel Bentham supports installing Brunel's block machinery at Portsmouth Dockyard, moving the system toward large-scale naval use.

Samuel Bentham recommends installation of Brunel's block-making machinery at Portsmouth Dockyard.

Brunel's machinery mechanises the sawing and preparation of timber blanks used to make Royal Navy pulley blocks.

Powered sawing equipment produced wooden blanks for the cases of naval pulley blocks. The design reduced manual operations between manufacturing stages.

The machinery was arranged to move workpieces between successive operations with reduced manual handling. The machinery required unusually accurate metalworking and maintenance.

The first series of Brunel's machines is installed to manufacture medium-sized pulley blocks.

A second series of Brunel's machines is installed to manufacture smaller pulley blocks.

Specialised machinery cuts repeated mortises and openings in block components with greater consistency than hand production.

Specially designed machines formed repeated openings and slots in block shells with consistent geometry. It provided an early model for integrated industrial manufacture.

Brunel's Portsmouth system shapes pulley-block shells by machine as part of an integrated production sequence.

A third series completed much of the mechanised equipment needed for larger ships' rigging blocks. The process reduced dependence on traditional individually shaped components.

A third series of machines for large pulley blocks completes the main block-making installation.

Isambard Kingdom Brunel is born in Portsea, Portsmouth, the son of engineer Marc Isambard Brunel and Sophia Kingdom.

The block-making plant is judged capable of meeting the Royal Navy's full requirement for pulley blocks.

The Portsmouth Block Mills produce about one hundred and thirty thousand pulley blocks using Brunel's mechanised system.

The block-making system demonstrates that a small mechanised workforce can replace much larger numbers of skilled manual workers.

The mechanised installation produced roughly one hundred and thirty thousand rigging blocks within the year. The installation demonstrates the adaptation of existing dock infrastructure.
