The punched-card loom (Jacquard machine)
A loom in which the pattern is set by a pack of pasteboard cards with punched holes: where there is a hole the thread rises, where there is none it stays down. The skill of a drawboy lifting warp threads by hand is replaced by a changeable set of instructions.
The machine was assembled in Lyon around 1804 by the Frenchman Joseph Marie Jacquard, developing the earlier work of Vaucanson, and through it Falcon's cards. The cards were laced into an endless chain, could be taken off and put on in minutes, and could be copied from a design, so that one and the same loom wove any picture while the picture was stored apart from the machine and travelled without it.
By 1812 there were 11,000 such looms in France. The separation of an unchanging machine from a changeable set of instructions, made for the sake of silk, turned out to matter more than the silk: the same idea would underpin Babbage's calculating engines.
Why this date
Britannica: the Jacquard system was developed in 1804-05; before that, in 1801, Jacquard showed an improved drawloom and was awarded a bronze medal for it. In 1806 the device was declared public property and the inventor received a pension and a royalty on each machine (Britannica). The English Wikipedia gives a patent of 1804; the axis value is the start of Britannica's interval, and the label keeps both years. Diffusion: by 1812 there were 11,000 such looms in use in France (Britannica).
What it grew from
-
A figured-weaving loom without a drawboy (Vaucanson)
improved · Confidence: high
Britannica states in two different articles that Jacquard's system improved on the punched card technology of Vaucanson's loom and that Vaucanson's mechanism served as the foundation for the successful Jacquard attachment.
Dispute: The line is not straight in two respects. First, Vaucanson replaced the chain of cards with a cylinder, while Jacquard went back to cards, so that he took the selecting mechanism from Vaucanson and the carrier of the record from Falcon. Second, Rojas warns that the very display at the Musée des Arts et Métiers imposes an evolutionist picture leading to Jacquard as an outcome. This is a warning against reading the series as an inevitable ladder, not a denial of the link itself.

The grande tire drawloom: the design as a set of cords and the work of the drawboy
improved · Confidence: high
The Jacquard machine is an attachment to the same figured loom, replacing the drawboy: the search for such a device began, according to Britannica, precisely because of the inconvenience and errors of the second worker, while at Lyon the grande tire loom survived until Jacquard and was gradually displaced by him.
Dispute: The replacement was slow and not a single victory: the Museum of the History of Lyon writes that the grande tire loom was used with gradual improvements right up to the arrival of the Jacquard mechanism and was displaced by it gradually. Moreover the Jacquard machine has two parents, and the sources do not undertake to apportion them: the selecting device comes from the Bouchon-Falcon-Vaucanson line, while the loom itself, with its cords, heddles and harness, comes from the drawloom.

What grew out of it
-
Babbage's Analytical Engine: a design that stayed on paper
influenced · Confidence: high
Babbage carried the weaving cards over to the calculating machine openly: he explained the design through the loom and called the analogy nearly perfect, kept a woven portrait of Jacquard at home and used it to show how the cards worked, and Ada Lovelace wrote that the engine weaves algebraical patterns just as the loom weaves flowers and leaves.

These patterns are then sent to a peculiar artist, who, by means of a certain machine, punches holes in a set of pasteboard cards in such a manner that when those cards are placed in a Jacquard loom, it will then weave upon its produce the exact pattern designed by the artist.
