# Not goggles — a patent drawing

> Steampunk's weakest register is brass accessories on a leather hat. Its strongest is the patent plate: a machine drawn as if somebody filed it, with a number and a date.

Most steampunk design is a list of objects: goggles, cogs, a top hat, a corset, more cogs. It's
the aesthetic as costume, and it's why the genre has a reputation.

The version that holds up isn't a costume at all. It's a document.

## What's a patent plate doing that a picture isn't?

Claiming the machine was real enough to register.

A patent drawing has dimension lines, section views, part numbers, an inventor's name and a filing
date. All of that is bureaucracy, and bureaucracy is what makes an invented device convincing —
somebody measured this, somebody argued about the claims, somebody paid a fee.

Same mechanism as
[a Latin name on an invented creature](/stories/monster-field-guide-illustration): the
label does the world-building, not the drawing.

## What are the conventions?

Six, and they're all functional.

- **Precise line work** with hatching for material, no shading.
- **Multiple views** — elevation, section, detail — arranged on one sheet.
- **Dimension lines** with arrowheads and figures.
- **Numbered part references** keyed to a description that isn't shown.
- **A patent number and date** in small capitals at the base.
- **Aged paper stock** as the ground, not a texture over the top.

The multiple views matter most. A single perspective drawing is an illustration; three orthogonal
views is a *filing*.

## What machine should it be?

Something with an unglamorous purpose.

The genre's instinct is airships and time machines. The better move is a device for a boring
problem, engineered absurdly: an apparatus for retrieving a hat from a river, a machine for
waking one specific person, a self-correcting umbrella.

Victorian patent archives are genuinely full of that, which is why the register works —
it's borrowing a real historical texture rather than a fictional one.

## Isn't steampunk a bit exhausted?

The costume version is. The document version has barely been used.

Which is worth separating, because the exhaustion is specific: goggles-and-cogs has been on every
market stall for fifteen years. Patent plates, technical sections, ships' plans and
[exploded assembly diagrams](/stories/mecha-instruction-manual-style) are a much larger
and less worn seam in the same world.

If a design would look at home on a stall, it's in the costume register. If it looks like a page
from an archive, it isn't.

## Is any of this someone else's?

Real patents are public documents — the drawings in patent archives are exactly the kind of thing
that ends up freely reproducible, which is why patent-print posters are an entire industry.

But **a real patent is a real invention with a real inventor's name on it**, and reproducing one
is copying a specific document rather than working in the tradition. Inventing the machine avoids
that entirely and is more interesting anyway.

The conventions themselves — dimension lines, part numbers, filing formats — are drafting
standards, not anyone's property.

## Does it print well?

Very. It's pure line at a scale that suits fabric.

One ink, no gradients, hard edges throughout, and a composition made of separated elements with
space between them. The one risk is the small type: patent numbers and part labels at real scale
drop below
[what the weave can hold](/stories/bold-shapes-survive-fabric), so they want to be larger
than a real sheet would set them.

Print it big and keep the labels few.

## What about the colour?

Sepia on cream is the obvious choice and the least interesting one.

The drawing is line, so it inverts cleanly — bone white on faded black reads as a blueprint's
cousin and looks considerably more modern. Brass on charcoal splits the difference.
[Line art is the one register that travels to any ground](/stories/line-art-single-color-prints),
so the garment colour is a free decision here.

## How do I get one made?

Describe the machine at [JustOG](/) — what boring problem it solves, and how absurdly — and say it
should be a patent plate. Pick a direction, drag the crop frame, see it composited on the real
garment, and it's made to order and shipped.

Designs other people have published are in the [shop](/shop).

Anyone can draw a machine. The filing date is what makes somebody believe it existed.
