Pattern-Making Explained to Children. (Steve Smith-Silk Mill Workshop Supervisor)

At the recent prototyping session held at the Silk Mill, participants from local Derby school, Dale Primary, one year 5 group chose to design a cardboard prototype display system for a selection of wooden foundry patterns from the Derby museum industrial collection.

The display case was to be in the form of an over-scoped two-part ‘cope and drag’ moulding box; the box split open to reveal the casting processes involving the wooden angled-gear patterns they had to work with. Team leader Yun Wing - an architect assistant for Bauman Lyons – and, me – Silk Mill Workshop Leader and a time-served industrial pattern-maker - were impressed young students grasped basically what the patterns did and how the colours represented important information after only a short explanation of how foundry equipment is used. And, as a consequence, they made a credible interpretation of how the patterns and pattern-making techniques used still today in the foundry industry could be displayed in the Museum of Making.

Consistently, pattern-making and foundry pattern equipment – actual patterns, core boxes, pattern-boards and associated running systems -   fascinate and puzzle foundry-industry outsiders simultaneously. Put another way, the colours, shapes and geometric profiles of patterns - their total form, exhibits a certain mysterious sculptural artistic attraction whilst, presented with these strange abstract objects, it seems hard for aesthetic admirers to understand the positive and negative aspects of sand or resin mould-making, the technical use of internal cores, core prints, loose pieces, shell patterns and other residual foundry models of production - their functions. To cite ‘Captain Veneer’, the alter ego of the under-known furniture designer Fred Baier, it as if patterns - taken out of their industrial context -  that “Form Swallows Function”. (Have a look at www.fredbaier.com)  

 A first-principle strategy for deconstructing the grammar of pattern-making is to explain the primary colour codes pattern-shops deploy to coat patterns with wear & moisture-prevention lacquers.

Fitting within a notional e20c modernist ‘archetypal’ aesthetic practice – I’m thinking the Dutch school of De Stijl and Piet Mondrian paintings, in particular, the well-known ‘Red-Blue Chair’ designed by Gerrit Rietveld (colour buttons on a black TV remote control, Channel 4 logo) - modern foundry patterns have traditionally been painted red, yellow, black, blue, with the occasional, rare, use of green.  

Pattern colours are not arbitrary, simply decorated in the individual creative style of the patternmaker, as was suggested during the Art of Artefacts workshops ran in 2016. They are standardised signs of a foundry industry colour code, which inform the moulders or other foundry professionals about the final details of the pattern (and final cast-product) they mould in sand, then cast in specified metals or alloys: Steel, cast iron, aluminium, bronze, or gun metal, say.

Red (all pattern-shops use differing industry brands with shade variations from scarlet to light orange hues) signifies an ‘as cast surface’. As-cast basically means that the parts of the pattern in red describe and represent the actual form and parts of the metal casting which will be left ‘as-they-are’. So, for example, they will not receive further machining and, as such, often texturaly reflect the pitted surface of the sand mould the metal was cast into. To provide an example from the Derby Museum collection you can compare this pattern for an angled gear wheel, made by Leicester crane makers Taylor & Hubbard.

On this pattern the red cog teeth (unlike perhaps contemporary CNC’d gear teeth) have the exact form - cut from hardwood by the pattern-maker from set calculations and geometry – to match another as-cast gear wheel. 

Such an un-machined angled gear wheel can be found outside the workshop, rusting away by the space-age looking Cochran Boiler; well worth a look.

A second example of how red denotes as-cast is this simple ‘shell’ pattern (a stand-alone pattern without core boxes or set on a mechanised moulding board).

The yellow areas paint-signified on a pattern, by contrast, indicate to the moulder or foundry foreman that this section of the pattern is a visual alert that the finished casting will be machined further – turned, milled, threaded, shaped or ground – to a fine mechanical tolerance. Acting on this special specification the moulder will make orientation decisions as to what part of the two-part moulding box the machined part of the component will be best sited: cope (top) or drag (base) – sometimes in a third mid box.

When fluid metal is cast the impurities – slag, gas holes, and sand inclusions – float up through the flowing hot material and embed in the top surface skin of the casting. To avoid this, key machined areas may be placed in the lower drag box, protecting the possibility of the casting being scrapped (“scrapper”) because the crucial bearing and jointing surfaces cannot be machined true, i.e. functionally perfect. Of course there are exceptions to this rule, when, perhaps in the case of the gear teeth, as-cast parts take priority - and the patternmaker adds a sufficient machining allowance onto extant drawing dimensions (2-10mm), anyway as an extra safeguard.

Black sections of patterns show something entirely different.  Known as core prints, these ‘positive’ pattern parts are not parts of a casting at all. They locate or support suspended or seated cores of sand that hollow out a casting and form the internal- ‘negative’ profile of a casting - as in an iron pipe or aluminium engine water pump.

(DM collection right-angled-pipe core box with pattern outline)

This has consequences for the production process, because black is also an alert to the worker on the foundry floor. It tells the moulder that accompanying this pattern is either one or more core boxes and that the mould should be set with certain cores pre-casting. Looking at the reverse side of the Taylor Hubbard pattern above then, a core box would exist that produced a cylindrical positive core of sand that is located top and bottom in the mould by the corresponding impressions left by the black core prints.

In other words the gear wheel is ‘cored out’ to take a spindle-drive shaft (see casting image and corebox right). It is also machined on three surfaces on this side and one bearing area on the teeth side - marked by yellow varnish. 

To see the machined and as cast sections of a casting, and how different castings fit together to make a machine, take a look inside any engine, machine shop or factory and examine the castings all around you. In the Silk Mill workshop a fine example is our  mortice jointer. The rougher sand cast sections are painted green - the fine milled or turned areas are the clean perfectly flat reworked parts of the moving components.

Certain patterns utilise loose pieces. Loose pieces are  sometimes located on dovetails or dowel pins – to aid the moulding of ‘un-mouldable’ parts such as ribs, bosses and overhanging rims or trims which are removed at 90° or 180° to the direction the pattern is withdrawn, usually extracted via the cavity left by the larger pattern body. The position of the loose piece is demarcated against the red of the as-cast area by contrasting green paint. In the case of a loose piece for a round boss, without the boss in place a green seating spot-circle on the red background of a pattern would once again alert the moulder to the incompleteness of the pattern kit and that the missing forming piece must be found and added to the pattern before moulding, certainly casting.

Blue patterns – and the code for blue - are something of a mystery to me. I was a pattern-maker for nearly a decade in a foundry and a master pattern shop: Butterley Foundry and Premier Patterns in Derby. But  never came to use/see blue paint. When the first stage of co-production was near completion I inserted the RE:Make RE: logo in the wheely-kitchen birch plywood bar. It seemed a fitting gesture to paint the industrial- De Stijl style – colours: red, yellow, and green on the lettering, using the black-for-core-print varnish for the blackboard core-print-style extrusion. 

To source this trade product, I went to Datum Patterns Derby. The foreman was helpful. We chatted about old days in Derby pattern shops and how things had changed and not changed (I ripped of the machined ply shapes I saw at Datum for the turned shell legs on the two seascape tables in the Nature Gallery at MAG – see clear competition pattern below). He said, after filling coffee jars with red, black, yellow and green,  “do you want some blue, too?” I said “what’s blue for...youth?” and he explained. Some patternshops paint their as-cast pattern parts this semi-light primary blue so that, on a visit to a foundry or works they are supplying, they can clearly spot their patterns from those being made in-house or by competitors painted variant hues of red. 

That is, a supplier calculates visually “how much work is coming his way- and not” by the presence/lack of blue. So the Datum foreman maintained. There are logical and practical faults with this coded system. But if you want to see a blue-painted pattern look to the ceiling of the ground floor in the Sowter Mill and there is a strut pattern made for clockmaker Smiths of Derby to form a casting for St Pauls Cathedral (I think) - the ‘ finger’ core prints which cored out bolt holes are over-painted, it is worth noting-spotting: have a look up-----

A final pattern coating worth explaining is clear varnish. Although sometimes used on the inside of split patterns, outside of core boxes, to protect the soft or hardwood formed body of the pattern/box from moisture ingress, clear varnish was normally only used as a standard application onto competition patterns. National or regional – I won the East Midlands Junior pattern-making competition in 1979 – contest regulations stipulated apprentices apply clear lacquer so that judges could spot overuse of fillers, mistakes, and lack of jointing techniques and incorrect use of grain directions in pattern constructions - all concealable with red, yellow and black varnish. Below is a competition pattern from the DM collection.

(the front darker mahogany three-boss removable section is a typical loose component - the concealed back of the piece and its dovetailed seating area would be painted the above-cited green)

Endnotes: 

1) At the April 2017 Furniture Jam I experimented again with pattern varnishes and foundry codes in making this bamboo plywood cabinet with thin painted shelves, seen here stacked together to reveal the range of foundry pattern colours explained above.

2) Images below the shelves display some of Fred Baier’s design and making work: Baier worked for a time as a patternmaker and often references industrial patternmaking in his work; The split pipe coffee table is two shell patterns assembled. Baier they say makes ‘techno-folk’ -- quirky  industrial geometric products. Crafted  by Baier, furniture often - paradoxically in relation to say Rietveld - get categorised as postmodern > ‘POMO’.
